text: This paper proposes a novel cooperative approach for two-hop amplify-and-forward
(A&F) relaying that exploits both the signal forwarded by the relay and the one
directly transmitted by the source in impulse-radio ultra-wideband (IR-UWB) systems.
Specifically, we focus on a non-coherent setup employing a double-differential
encoding scheme at the source node and a single differential demodulation at the
relay and destination. The log-likelihood ratio based decision rule is derived
at the destination node. A semi-analytical power allocation strategy is presented
by evaluating a closed-form expression for the effective signal to noise ratio
(SNR) at the destination, which is maximized by exhaustive search. Numerical simulations
show that the proposed system outperforms both the direct transmission with single
differential encoding and the non-cooperative multi-hop approach in different
scenarios.

text: The Seebeck coefficients, electrical resistivities, total thermal conductivities,
and magnetization are reported for temperatures between 5 and 350 K for n-type
Bi0.88Sb0.12 nano-composite alloys made by Ho-doping at the 0, 1, and 3 % atomic
levels. The alloys were prepared using a dc hot-pressing method, and are shown
to be single phase for both Ho contents with grain sizes on the average of 900
nm. We find the parent compound has a maximum of ZT = 0.28 at 231 K, while doping
1 % Ho increases the maximum ZT to 0.31 at 221 K and the 3 % doped sample suppresses
the maximum ZT = 0.24 at a temperature of 260 K.

text: 'Carbon has been used widely as the basis of porous cathodes for nonaqueous
Li–O2 cells. However, the stability of carbon and the effect of carbon on electrolyte
decomposition in such cells are complex and depend on the hydrophobicity/hydrophilicity
of the carbon surface. Analyzing carbon cathodes, cycled in Li–O2 cells between
2 and 4 V, using acid treatment and Fenton’s reagent, and combined with differential
electrochemical mass spectrometry and FTIR, demonstrates the following: Carbon
is relatively stable below 3.5 V (vs Li/Li+) on discharge or charge, especially
so for hydrophobic carbon, but is unstable on charging above 3.5 V (in the presence
of Li2O2), oxidatively decomposing to form Li2CO3. Direct chemical reaction with
Li2O2 accounts for only a small proportion of the total carbon decomposition on
cycling. Carbon promotes electrolyte decomposition during discharge and charge
in a Li–O2 cell, giving rise to Li2CO3 and Li carboxylates (DMSO and tetraglyme
electrolytes). The Li2CO3 and Li carboxylates present at the end of discharge
and those that form on charge result in polarization on the subsequent charge.
Li2CO3 (derived from carbon and from the electrolyte) as well as the Li carboxylates
(derived from the electrolyte) decompose and form on charging. Oxidation of Li2CO3
on charging to ∼4 V is incomplete; Li2CO3 accumulates on cycling resulting in
electrode passivation and capacity fading. Hydrophilic carbon is less stable and
more catalytically active toward electrolyte decomposition than carbon with a
hydrophobic surface. If the Li–O2 cell could be charged at or below 3.5 V, then
carbon may be relatively stable, however, its ability to promote electrolyte decomposition,
presenting problems for its use in a practical Li–O2 battery. The results emphasize
that stable cycling of Li2O2 at the cathode in a Li–O2 cell depends on the synergy
between electrolyte and electrode; the stability of the electrode and the electrolyte
cannot be considered in isolation.'

text: Energy‐storage technologies, including electrical double‐layer capacitors
and rechargeable batteries, have attracted significant attention for applications
in portable electronic devices, electric vehicles, bulk electricity storage at
power stations, and “load leveling” of renewable sources, such as solar energy
and wind power. Transforming lithium batteries and electric double‐layer capacitors
requires a step change in the science underpinning these devices, including the
discovery of new materials, new electrochemistry, and an increased understanding
of the processes on which the devices depend. The Review will consider some of
the current scientific issues underpinning lithium batteries and electric double‐layer
capacitors.

text: The rechargeable nonaqueous lithium-air (Li-O2) battery is receiving a great
deal of interest because, theoretically, its specific energy far exceeds the best
that can be achieved with lithium-ion cells. Operation of the rechargeable Li-O2
battery depends critically on repeated and highly reversible formation/decomposition
of lithium peroxide (Li2O2) at the cathode upon cycling. Here, we show that this
process is possible with the use of a dimethyl sulfoxide electrolyte and a porous
gold electrode (95% capacity retention from cycles 1 to 100), whereas previously
only partial Li2O2 formation/decomposition and limited cycling could occur. Furthermore,
we present data indicating that the kinetics of Li2O2 oxidation on charge is approximately
10 times faster than on carbon electrodes.

text: Stability of the electrolyte toward reduced oxygen species generated at the
cathode is a crucial challenge for the rechargeable nonaqueous Li–O2 battery.
Here, we investigate dimethylformamide as the basis of an electrolyte. Although
reactions at the O2 cathode on the first discharge–charge cycle are dominated
by reversible Li2O2 formation/decomposition, there is also electrolyte decomposition,
which increases on cycling. The products of decomposition at the cathode on discharge
are Li2O2, Li2CO3, HCO2Li, CH3CO2Li, NO, H2O, and CO2. Li2CO3 accumulates in the
electrode with cycling. The stability of dimethylformamide toward reduced oxygen
species is insufficient for its use in the rechargeable nonaqueous Li–O2 battery.

text: Decades of research in distributed computing have led to a variety of perspectives
on what it means for a concurrent algorithm to be efficient, depending on model
assumptions, progress guarantees, and complexity metrics. It is therefore natural
to ask whether one could compose algorithms that perform efficiently under different
conditions, so that the composition preserves the performance of the original
components when their conditions are met. In this paper, we evaluate the cost
of composing shared-memory algorithms. First, we formally define the notion of
safely composable algorithms and we show that every sequential type has a safely
composable implementation, as long as enough state is transferred between modules.
Since such generic implementations are inherently expensive, we present a more
general light-weight specification that allows the designer to transfer very little
state between modules, by taking advantage of the semantics of the implemented
object. Using this framework, we implement a composed longlived test-and-set object,
with the property that each of its modules is asymptotically optimal with respect
to the progress condition it ensures, while the entire implementation only uses
objects with consensus number at most two. Thus, we show that the overhead of
composition can be negligible in the case of some important shared-memory abstractions.

text: Renaming is a fundamental problem in distributed computing, in which a set
of n processes need to pick unique names from a namespace of limited size. In
this paper, we present the first early-deciding upper bounds for synchronous renaming,
in which the running time adapts to the actual number of failures f in the execution.
We show that, surprisingly, renaming can be solved in constant time if the number
of failures f is limited to O(√n), while for general f ≤ n - 1 renaming can always
be solved in O(log f) communication rounds. In the wait-free case, i.e. for f
= n - 1, our upper bounds match the Ω(log n) lower bound of Chaudhuri et al. [13].

text: Set agreement is a fundamental problem in distributed computing in which processes
collectively choose a small subset of values from a larger set of proposals. The
impossibility of fault-tolerant set agreement in asynchronous networks is one
of the seminal results in distributed computing. In synchronous networks, too,
the complexity of set agreement has been a significant research challenge that
has now been resolved. Real systems, however, are neither purely synchronous nor
purely asynchronous. Rather, they tend to alternate between periods of synchrony
and periods of asynchrony. Nothing specific is known about the complexity of set
agreement in such a "partially synchronous" setting. In this paper,
we address this challenge, presenting the first (asymptotically) tight bound on
the complexity of set agreement in such systems. We introduce a novel technique
for simulating, in a fault-prone asynchronous shared memory, executions of an
asynchronous and failure-prone message-passing system in which some fragments
appear synchronous to some processes. We use this simulation technique to derive
a lower bound on the round complexity of set agreement in a partially synchronous
system by a reduction from asynchronous wait-free set agreement. Specifically,
we show that every set agreement protocol requires at least $\lfloor\frac t k
\rfloor + 2$ synchronous rounds to decide. We present an (asymptotically) matching
algorithm that relies on a distributed asynchrony detection mechanism to decide
as soon as possible during periods of synchrony. From these two results, we derive
the size of the minimal window of synchrony needed to solve set agreement. By
relating synchronous, asynchronous and partially synchronous environments, our
simulation technique is of independent interest. In particular, it allows us to
obtain a new lower bound on the complexity of early deciding k-set agreement complementary
to that of Gafni et al. (in SIAM J. Comput. 40(1):63-78, 2011), and to re-derive
the combinatorial topology lower bound of Guerraoui et al. (in Theor. Comput.
Sci. 410(6-7):570-580, 2009) in an algorithmic way.

text: 'Asynchronous task allocation is a fundamental problem in distributed computing
in which p asynchronous processes must execute a set of m tasks. Also known as
write-all or do-all, this problem been studied extensively, both independently
and as a key building block for various distributed algorithms. In this paper,
we break new ground on this classic problem: we introduce the To-Do Tree concurrent
data structure, which improves on the best known randomized and deterministic
upper bounds. In the presence of an adaptive adversary, the randomized To-Do Tree
algorithm has O(m + p log p log2 m) work complexity. We then show that there exists
a deterministic variant of the To-Do Tree algorithm with work complexity O(m +
p log5 m log2 max(m, p)). For all values of m and p, our algorithms are within
log factors of the Ω(m + p log p) lower bound for this problem. The key technical
ingredient in our results is a new approach for analyzing concurrent executions
against a strong adaptive scheduler. This technique allows us to handle the complex
dependencies between the processes'' coin flips and their scheduling, and to tightly
bound the work needed to perform subsets of the tasks.'

text: Synchronous distributed algorithms are easier to design and prove correct
than algorithms that tolerate asynchrony. Yet, in the real world, networks experience
asynchrony and other timing anomalies. In this paper, we address the question
of how to efficiently transform an algorithm that relies on synchronous timing
into an algorithm that tolerates asynchronous executions. We introduce a transformation
technique from synchronous algorithms to indulgent algorithms (Guerraoui, in PODC,
pp. 289-297, 2000), which induces only a constant overhead in terms of time complexity
in well-behaved executions. Our technique is based on a new abstraction we call
an asynchrony detector, which the participating processes implement collectively.
The resulting transformation works for the class of colorless distributed tasks,
including consensus and set agreement. Interestingly, we also show that our technique
is relevant for colored tasks, by applying it to the renaming problem, to obtain
the first indulgent renaming algorithm.

text: Although studies on laboratory species and natural populations of vertebrates
have shown reproduction to impair later performance, little is known of the age‐specific
associations between reproduction and survival, and how such findings apply to
the ageing of large, long‐lived species. Herein we develop a framework to examine
population‐level patterns of reproduction and survival across lifespan in long‐lived
organisms, and decompose those changes into individual‐level effects, and the
effects of age‐specific trade‐offs between fitness components. We apply this to
an extensive longitudinal dataset on female semi‐captive Asian timber elephants
(Elephas maximus) and report the first evidence of age‐specific fitness declines
that are driven by age‐specific associations between fitness components in a long‐lived
mammal. Associations between reproduction and survival are positive in early life,
but negative in later life with up to 71% of later‐life survival declines associated
with investing in the production of offspring within this population of this critically
endangered species.

text: Female mate choice acts as an important evolutionary force, yet the influence
of the environment on both its expression and the selective pressures acting upon
it remains unknown. We found consistent heritable differences between females
in their choice of mate based on ornament size during a 25‐year study of a population
of collared flycatchers. However, the fitness consequences of mate choice were
dependent on environmental conditions experienced whilst breeding. Females breeding
with highly ornamented males experienced high relative fitness during dry summer
conditions, but low relative fitness during wetter years. Our results imply that
sexual selection within a population can be highly variable and dependent upon
the prevailing weather conditions experienced by individuals.

text: We present an analysis of finite-size effects in jammed packings of N soft,
frictionless spheres at zero temperature. There is a 1/N correction to the discrete
jump in the contact number at the transition so that jammed packings exist only
above isostaticity. As a result, the canonical power-law scalings of the contact
number and elastic moduli break down at low pressure. These quantities exhibit
scaling collapse with a nontrivial scaling function, demonstrating that the jamming
transition can be considered a phase transition. Scaling is achieved as a function
of N in both two and three dimensions, indicating an upper critical dimension
of 2.

text: Fungal cell walls frequently contain a polymer of mannose and galactose called
galactomannan. In the pathogenic filamentous fungus Aspergillus fumigatus, this
polysaccharide is made of a linear mannan backbone with side chains of galactofuran
and is anchored to the plasma membrane via a glycosylphosphatidylinositol or is
covalently linked to the cell wall. To date, the biosynthesis and significance
of this polysaccharide are unknown. The present data demonstrate that deletion
of the Golgi UDP-galactofuranose transporter GlfB or the GDP-mannose transporter
GmtA leads to the absence of galactofuran or galactomannan, respectively. This
indicates that the biosynthesis of galactomannan probably occurs in the lumen
of the Golgi apparatus and thus contrasts with the biosynthesis of other fungal
cell wall polysaccharides studied to date that takes place at the plasma membrane.
Transglycosylation of galactomannan from the membrane to the cell wall is hypothesized
because both the cell wall-bound and membrane-bound polysaccharide forms are affected
in the generated mutants. Considering the severe growth defect of the A. fumigatus
GmtA-deficient mutant, proving this paradigm might provide new targets for antifungal
therapy.

text: In dynamical models of cortical networks, the recurrent connectivity can amplify
the input given to the network in two distinct ways. One is induced by the presence
of near-critical eigenvalues in the connectivity matrix W, producing large but
slow activity fluctuations along the corresponding eigenvectors (dynamical slowing).
The other relies on W not being normal, which allows the network activity to make
large but fast excursions along specific directions. Here we investigate the trade-off
between non-normal amplification and dynamical slowing in the spontaneous activity
of large random neuronal networks composed of excitatory and inhibitory neurons.
We use a Schur decomposition of W to separate the two amplification mechanisms.
Assuming linear stochastic dynamics, we derive an exact expression for the expected
amount of purely non-normal amplification. We find that amplification is very
limited if dynamical slowing must be kept weak. We conclude that, to achieve strong
transient amplification with little slowing, the connectivity must be structured.
We show that unidirectional connections between neurons of the same type together
with reciprocal connections between neurons of different types, allow for amplification
already in the fast dynamical regime. Finally, our results also shed light on
the differences between balanced networks in which inhibition exactly cancels
excitation and those where inhibition dominates.

text: Using correlated live-cell imaging and electron tomography we found that actin
branch junctions in protruding and treadmilling lamellipodia are not concentrated
at the front as previously supposed, but link actin filament subsets in which
there is a continuum of distances from a junction to the filament plus ends, for
up to at least 1 mm. When branch sites were observed closely spaced on the same
filament their separation was commonly a multiple of the actin helical repeat
of 36 nm. Image averaging of branch junctions in the tomograms yielded a model
for the in vivo branch at 2.9 nm resolution, which was comparable with that derived
for the in vitro actin- Arp2/3 complex. Lamellipodium initiation was monitored
in an intracellular wound-healing model and was found to involve branching from
the sides of actin filaments oriented parallel to the plasmalemma. Many filament
plus ends, presumably capped, terminated behind the lamellipodium tip and localized
on the dorsal and ventral surfaces of the actin network. These findings reveal
how branching events initiate and maintain a network of actin filaments of variable
length, and provide the first structural model of the branch junction in vivo.
A possible role of filament capping in generating the lamellipodium leaflet is
discussed and a mathematical model of protrusion is also presented.

text: The Staphylococcus aureus cell wall stress stimulon (CWSS) is activated by
cell envelope-targeting antibiotics or depletion of essential cell wall biosynthesis
enzymes. The functionally uncharacterized S. aureus LytR-CpsA-Psr (LCP) proteins,
MsrR, SA0908 and SA2103, all belong to the CWSS. Although not essential, deletion
of all three LCP proteins severely impairs cell division. We show here that VraSR-dependent
CWSS expression was up to 250-fold higher in single, double and triple LCP mutants
than in wild type S. aureus in the absence of external stress. The LCP triple
mutant was virtually depleted of wall teichoic acids (WTA), which could be restored
to different degrees by any of the single LCP proteins. Subinhibitory concentrations
of tunicamycin, which inhibits the first WTA synthesis enzyme TarO (TagO), could
partially complement the severe growth defect of the LCP triple mutant. Both of
the latter findings support a role for S. aureus LCP proteins in late WTA synthesis,
as in Bacillus subtilis where LCP proteins were recently proposed to transfer
WTA from lipid carriers to the cell wall peptidoglycan. Intrinsic activation of
the CWSS upon LCP deletion and the fact that LCP proteins were essential for WTA-loading
of the cell wall, highlight their important role(s) in S. aureus cell envelope
biogenesis.

text: Plants exhibit a unique developmental flexibility to ever-changing environmental
conditions. To achieve their profound adaptability, plants are able to maintain
permanent stem cell populations and form new organs during the entire plant life
cycle. Signaling substances, called plant hormones, such as auxin, cytokinin,
abscisic acid, brassinosteroid, ethylene, gibberellin, jasmonic acid, and strigolactone,
govern and coordinate these developmental processes. Physiological and genetic
studies have dissected the molecular components of signal perception and transduction
of the individual hormonal pathways. However, over recent years it has become
evident that hormones do not act only in a linear pathway. Hormonal pathways are
interconnected by a complex network of interactions and feedback circuits that
determines the final outcome of the individual hormone actions. This raises questions
about the molecular mechanisms underlying hormonal cross talk and about how these
hormonal networks are established, maintained, and modulated throughout plant
development.

text: The architecture of a plant's root system, established postembryonically,
results from both coordinated root growth and lateral root branching. The plant
hormones auxin and cytokinin are central endogenous signaling molecules that regulate
lateral root organogenesis positively and negatively, respectively. Tight control
and mutual balance of their antagonistic activities are particularly important
during the early phases of lateral root organogenesis to ensure continuous lateral
root initiation (LRI) and proper development of lateral root primordia (LRP).
Here, we show that the early phases of lateral root organogenesis, including priming
and initiation, take place in root zones with a repressed cytokinin response.
Accordingly, ectopic overproduction of cytokinin in the root basal meristem most
efficiently inhibits LRI. Enhanced cytokinin responses in pericycle cells between
existing LRP might restrict LRI near existing LRP and, when compromised, ectopic
LRI occurs. Furthermore, our results demonstrate that young LRP are more sensitive
to perturbations in the cytokinin activity than are developmentally more advanced
primordia. We hypothesize that the effect of cytokinin on the development of primordia
possibly depends on the robustness and stability of the auxin gradient.

text: Whether or not evolutionary change is inherently irreversible remains a controversial
topic. Some examples of evolutionary irreversibility are known; however, this
question has not been comprehensively addressed at the molecular level. Here,
we use data from 221 human genes with known pathogenic mutations to estimate the
rate of irreversibility in protein evolution. For these genes, we reconstruct
ancestral amino acid sequences along the mammalian phylogeny and identify ancestral
amino acid states that match known pathogenic mutations. Such cases represent
inherent evolutionary irreversibility because, at the present moment, reversals
to these ancestral amino acid states are impossible for the human lineage. We
estimate that approximately 10% of all amino acid substitutions along the mammalian
phylogeny are irreversible, such that a return to the ancestral amino acid state
would lead to a pathogenic phenotype. For a subset of 51 genes with high rates
of irreversibility, as much as 40% of all amino acid evolution was estimated to
be irreversible. Because pathogenic phenotypes do not resemble ancestral phenotypes,
the molecular nature of the high rate of irreversibility in proteins is best explained
by evolution with a high prevalence of compensatory, epistatic interactions between
amino acid sites. Under such mode of protein evolution, once an amino acid substitution
is fixed, the probability of its reversal declines as the protein sequence accumulates
changes that affect the phenotypic manifestation of the ancestral state. The prevalence
of epistasis in evolution indicates that the observed high rate of irreversibility
in protein evolution is an inherent property of protein structure and function.

text: The 1H dipolar network, which is the major obstacle for applying proton detection
in the solid-state, can be reduced by deuteration, employing the RAP (Reduced
Adjoining Protonation) labeling scheme, which yields random protonation at non-exchangeable
sites. We present here a systematic study on the optimal degree of random sidechain
protonation in RAP samples as a function of the MAS (magic angle spinning) frequency.
In particular, we compare 1H sensitivity and linewidth of a microcrystalline protein,
the SH3 domain of chicken α-spectrin, for samples, prepared with 5–25 % H2O in
the E. coli growth medium, in the MAS frequency range of 20–60 kHz. At an external
field of 19.96 T (850 MHz), we find that using a proton concentration between
15 and 25 % in the M9 medium yields the best compromise in terms of sensitivity
and resolution, with an achievable average 1H linewidth on the order of 40–50
Hz. Comparing sensitivities at a MAS frequency of 60 versus 20 kHz, a gain in
sensitivity by a factor of 4–4.5 is observed in INEPT-based 1H detected 1D 1H,13C
correlation experiments. In total, we find that spectra recorded with a 1.3 mm
rotor at 60 kHz have almost the same sensitivity as spectra recorded with a fully
packed 3.2 mm rotor at 20 kHz, even though ~20× less material is employed. The
improved sensitivity is attributed to 1H line narrowing due to fast MAS and to
the increased efficiency of the 1.3 mm coil.

time scales can be detected and quantified by solid-state NMR spectroscopy. We
show two independent approaches that measure the effect of conformational exchange
on transverse relaxation parameters, namely Carr–Purcell–Meiboom–Gill relaxation-dispersion
experiments and measurement of differential multiple-quantum coherence decay.
Long coherence lifetimes, as required for these experiments, are achieved by the
use of highly deuterated samples and fast magic-angle spinning. The usefulness
of the approaches is demonstrated by application to microcrystalline ubiquitin.
We detect a conformational exchange process in a region of the protein for which
dynamics have also been observed in solution. Interestingly, quantitative analysis
of the data reveals that the exchange process is more than 1 order of magnitude
slower than in solution, and this points to the impact of the crystalline environment
on free energy barriers.

text: Recent advances in NMR spectroscopy and the availability of high magnetic
field strengths now offer the possibility to record real-time 3D NMR spectra of
short-lived protein states, e.g., states that become transiently populated during
protein folding. Here we present a strategy for obtaining sequential NMR assignments
as well as atom-resolved information on structural and dynamic features within
a folding intermediate of the amyloidogenic protein β2-microglobulin that has
a half-lifetime of only 20 min.

text: Partial deuteration is a powerful tool to increase coherence life times and
spectral resolution in proton solid-state NMR. The J coupling to deuterium needs,
however, to be decoupled to maintain the good resolution in the (usually indirect)
13C dimension(s). We present a simple and reversible way to expand a commercial
1.3 mm HCN MAS probe with a 2H channel with sufficient field strength for J-decoupling
of deuterium, namely 2–3 kHz. The coil is placed at the outside of the stator
and requires no significant modifications to the probe. The performance and the
realizable gains in sensitivity and resolution are demonstrated using perdeuterated
ubiquitin, with selectively CHD2-labeled methyl groups.

text: 'ackground: The evolution and genomic stop codon frequencies have not been
rigorously studied with the exception of coding of non-canonical amino acids.
Here we study the rate of evolution and frequency distribution of stop codons
in bacterial genomes.Results: We show that in bacteria stop codons evolve slower
than synonymous sites, suggesting the action of weak negative selection. However,
the frequency of stop codons relative to genomic nucleotide content indicated
that this selection regime is not straightforward. The frequency of TAA and TGA
stop codons is GC-content dependent, with TAA decreasing and TGA increasing with
GC-content, while TAG frequency is independent of GC-content. Applying a formal,
analytical model to these data we found that the relationship between stop codon
frequencies and nucleotide content cannot be explained by mutational biases or
selection on nucleotide content. However, with weak nucleotide content-dependent
selection on TAG, -0.5 < Nes < 1.5, the model fits all of the data and recapitulates
the relationship between TAG and nucleotide content. For biologically plausible
rates of mutations we show that, in bacteria, TAG stop codon is universally associated
with lower fitness, with TAA being the optimal for G-content < 16% while for G-content
> 16% TGA has a higher fitness than TAG.Conclusions: Our data indicate that TAG
codon is universally suboptimal in the bacterial lineage, such that TAA is likely
to be the preferred stop codon for low GC content while the TGA is the preferred
stop codon for high GC content. The optimization of stop codon usage may therefore
be useful in genome engineering or gene expression optimization applications.Reviewers:

text: 'The main forces directing long-term molecular evolution remain obscure. A
sizable fraction of amino-acid substitutions seem to be fixed by positive selection,
but it is unclear to what degree long-term protein evolution is constrained by
epistasis, that is, instances when substitutions that are accepted in one genotype
are deleterious in another. Here we obtain a quantitative estimate of the prevalence
of epistasis in long-term protein evolution by relating data on amino-acid usage
in 14 organelle proteins and 2 nuclear-encoded proteins to their rates of short-term
evolution. We studied multiple alignments of at least 1,000 orthologues for each
of these 16 proteins from species from a diverse phylogenetic background and found
that an average site contained approximately eight different amino acids. Thus,
without epistasis an average site should accept two-fifths of all possible amino
acids, and the average rate of amino-acid substitutions should therefore be about
three-fifths lower than the rate of neutral evolution. However, we found that
the measured rate of amino-acid substitution in recent evolution is 20 times lower
than the rate of neutral evolution and an order of magnitude lower than that expected
in the absence of epistasis. These data indicate that epistasis is pervasive throughout
protein evolution: about 90 per cent of all amino-acid substitutions have a neutral
or beneficial impact only in the genetic backgrounds in which they occur, and
must therefore be deleterious in a different background of other species. Our
findings show that most amino-acid substitutions have different fitness effects
in different species and that epistasis provides the primary conceptual framework
to describe the tempo and mode of long-term protein evolution.'

text: In this Letter, we explore experimentally the phase behavior of a dense active
suspension of self-propelled colloids. In addition to a solidlike and gaslike
phase observed for high and low densities, a novel cluster phase is reported at
intermediate densities. This takes the form of a stationary assembly of dense
aggregates—resulting from a permanent dynamical merging and separation of active
colloids—whose average size grows with activity as a linear function of the self-propelling
velocity. While different possible scenarios can be considered to account for
these observations—such as a generic velocity weakening instability recently put
forward—we show that the experimental results are reproduced mathematically by
a chemotactic aggregation mechanism, originally introduced to account for bacterial
aggregation and accounting here for diffusiophoretic chemical interaction between
colloidal swimmers.

text: 'We demonstrate how to appropriately estimate the zero-frequency (static)
hyperpolarizability of an organic molecule from its charge distribution, and we
explore applications of these estimates for identifying and evaluating new organic
nonlinear optical (NLO) materials. First, we calculate hyperpolarizabilities from
Hartree-Fock-derived charge distributions and find order-of-magnitude agreement
with experimental values. We show that these simple arithmetic calculations will
enable systematic searches for new organic NLO molecules. Second, we derive hyperpolarizabilities
from crystallographic data using a multipolar charge-density analysis and find
good agreement with empirical calculations. This demonstrates an experimental
determination of the full static hyperpolarizability tensor in a solid-state sample. '

text: "In models of radiative–convective equilibrium it is known that convection
can spontaneously aggregate into one single localized moist region if the domain
is large enough. The large changes in the mean climate state and radiative fluxes
accompanying this self-aggregation raise questions as to what simulations at lower
resolutions with parameterized convection, in similar homogeneous geometries,
should be expected to produce to be considered successful in mimicking a cloud-resolving
model.\r\nThe authors investigate this self-aggregation in a nonrotating, three-dimensional
cloud-resolving model on a square domain without large-scale forcing. It is found
that self-aggregation is sensitive not only to the domain size, but also to the
horizontal resolution. With horizontally homogeneous initial conditions, convective
aggregation only occurs on domains larger than about 200km and with resolutions
coarser than about 2km in the model examined. The system exhibits hysteresis,
so that with aggregated initial conditions, convection remains aggregated even
at our finest resolution, 500m, as long as the domain is greater than 200–300km.\r\nThe
sensitivity of self-aggregation to resolution and domain size in this model is
due to the sensitivity of the distribution of low clouds to these two parameters.
Indeed, the mechanism responsible for the aggregation of convection is the dynamical
response to the longwave radiative cooling from low clouds. Strong longwave cooling
near cloud top in dry regions forces downward motion, which by continuity generates
inflow near cloud top and near-surface outflow from dry regions. This circulation
results in the net export of moist static energy from regions with low moist static
energy, yielding a positive feedback."

text: The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes
DNA demethylation before fertilization, but the targeting preferences, mechanism,
and biological significance of this process remain unclear. Here, we show that
active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for
all of the demethylation in the central cell and preferentially targets small,
AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative
cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation
of similar sequences, and lack of DEMETER in vegetative cells causes reduced small
RNA–directed DNA methylation of transposons in sperm. Our results demonstrate
that demethylation in companion cells reinforces transposon methylation in plant
gametes and likely contributes to stable silencing of transposable elements across
generations.

text: The most well-studied function of DNA methylation in eukaryotic cells is the
transcriptional silencing of genes and transposons. More recent results showed
that many eukaryotes methylate the bodies of genes as well and that this methylation
correlates with transcriptional activity rather than repression. The purpose of
gene body methylation remains mysterious, but is potentially related to the histone
variant H2A.Z. Studies in plants and animals have shown that the genome-wide distributions
of H2A.Z and DNA methylation are strikingly anticorrelated. Furthermore, we and
other investigators have shown that this relationship is likely to be the result
of an ancient but unknown mechanism by which DNA methylation prevents the incorporation
of H2A.Z. Recently, we discovered strong correlations between the presence of
H2A.Z within gene bodies, the degree to which a gene's expression varies across
tissue types or environmental conditions, and transcriptional misregulation in
an h2a.z mutant. We propose that one basal function of gene body methylation is
the establishment of constitutive expression patterns within housekeeping genes
by excluding H2A.Z from their bodies.

text: Due to the omnipresent risk of epidemics, insect societies have evolved sophisticated
disease defences at the individual and colony level. An intriguing yet little
understood phenomenon is that social contact to pathogen-exposed individuals reduces
susceptibility of previously naive nestmates to this pathogen. We tested whether
such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium
anisopliae is based on active upregulation of the immune system of nestmates following
contact to an infectious individual or passive protection via transfer of immune
effectors among group members—that is, active versus passive immunisation. We
found no evidence for involvement of passive immunisation via transfer of antimicrobials
among colony members. Instead, intensive allogrooming behaviour between naive
and pathogen-exposed ants before fungal conidia firmly attached to their cuticle
suggested passage of the pathogen from the exposed individuals to their nestmates.
By tracing fluorescence-labelled conidia we indeed detected frequent pathogen
transfer to the nestmates, where they caused low-level infections as revealed
by growth of small numbers of fungal colony forming units from their dissected
body content. These infections rarely led to death, but instead promoted an enhanced
ability to inhibit fungal growth and an active upregulation of immune genes involved
in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there
was no upregulation of the gene cathepsin L, which is associated with antibacterial
and antiviral defences, and we found no increased antibacterial activity of nestmates
of fungus-exposed ants. This indicates that social immunisation after fungal exposure
is specific, similar to recent findings for individual-level immune priming in
invertebrates. Epidemiological modeling further suggests that active social immunisation
is adaptive, as it leads to faster elimination of the disease and lower death
rates than passive immunisation. Interestingly, humans have also utilised the
protective effect of low-level infections to fight smallpox by intentional transfer
of low pathogen doses (“variolation” or “inoculation”).

text: Due to the omnipresent risk of epidemics, insect societies have evolved sophisticated
disease defences at the individual and colony level. An intriguing yet little
understood phenomenon is that social contact to pathogen-exposed individuals reduces
susceptibility of previously naive nestmates to this pathogen. We tested whether
such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium
anisopliae is based on active upregulation of the immune system of nestmates following
contact to an infectious individual or passive protection via transfer of immune
effectors among group members—that is, active versus passive immunisation. We
found no evidence for involvement of passive immunisation via transfer of antimicrobials
among colony members. Instead, intensive allogrooming behaviour between naive
and pathogen-exposed ants before fungal conidia firmly attached to their cuticle
suggested passage of the pathogen from the exposed individuals to their nestmates.
By tracing fluorescence-labelled conidia we indeed detected frequent pathogen
transfer to the nestmates, where they caused low-level infections as revealed
by growth of small numbers of fungal colony forming units from their dissected
body content. These infections rarely led to death, but instead promoted an enhanced
ability to inhibit fungal growth and an active upregulation of immune genes involved
in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there
was no upregulation of the gene cathepsin L, which is associated with antibacterial
and antiviral defences, and we found no increased antibacterial activity of nestmates
of fungus-exposed ants. This indicates that social immunisation after fungal exposure
is specific, similar to recent findings for individual-level immune priming in
invertebrates. Epidemiological modeling further suggests that active social immunisation
is adaptive, as it leads to faster elimination of the disease and lower death
rates than passive immunisation. Interestingly, humans have also utilised the
protective effect of low-level infections to fight smallpox by intentional transfer
of low pathogen doses (“variolation” or “inoculation”).

text: 'We propose a two-step procedure for estimating multiple migration rates in
an approximate Bayesian computation (ABC) framework, accounting for global nuisance
parameters. The approach is not limited to migration, but generally of interest
for inference problems with multiple parameters and a modular structure (e.g.
independent sets of demes or loci). We condition on a known, but complex demographic
model of a spatially subdivided population, motivated by the reintroduction of
Alpine ibex (Capra ibex) into Switzerland. In the first step, the global parameters
ancestral mutation rate and male mating skew have been estimated for the whole
population in Aeschbacher et al. (Genetics 2012; 192: 1027). In the second step,
we estimate in this study the migration rates independently for clusters of demes
putatively connected by migration. For large clusters (many migration rates),
ABC faces the problem of too many summary statistics. We therefore assess by simulation
if estimation per pair of demes is a valid alternative. We find that the trade-off
between reduced dimensionality for the pairwise estimation on the one hand and
lower accuracy due to the assumption of pairwise independence on the other depends
on the number of migration rates to be inferred: the accuracy of the pairwise
approach increases with the number of parameters, relative to the joint estimation
approach. To distinguish between low and zero migration, we perform ABC-type model
comparison between a model with migration and one without. Applying the approach
to microsatellite data from Alpine ibex, we find no evidence for substantial gene
flow via migration, except for one pair of demes in one direction.'

text: To fight infectious diseases, host immune defences are employed at multiple
levels. Sanitary behaviour, such as pathogen avoidance and removal, acts as a
first line of defence to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care towards pathogen-exposed group members [2].
One of the most common behaviours is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores as it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behaviour extends current understanding of grooming and the establishment of social
immunity in insect societies.

f:I→I whose number of periodic points Pn(f)=∣{x∈I:fnx=x}∣ grows faster than any
ahead given sequence along a subsequence nk=3k. This example also shows that ‘non-flatness’
of critical points is necessary for the Martens–de Melo–van Strien theorem [M.

text: A subject of extensive study in evolutionary theory has been the issue of
how neutral, redundant copies can be maintained in the genome for long periods
of time. Concurrently, examples of adaptive gene duplications to various environmental
conditions in different species have been described. At this point, it is too
early to tell whether or not a substantial fraction of gene copies have initially
achieved fixation by positive selection for increased dosage. Nevertheless, enough
examples have accumulated in the literature that such a possibility should be
considered. Here, I review the recent examples of adaptive gene duplications and
make an attempt to draw generalizations on what types of genes may be particularly
prone to be selected for under certain environmental conditions. The identification
of copy-number variation in ecological field studies of species adapting to stressful
or novel environmental conditions may improve our understanding of gene duplications
as a mechanism of adaptation and its relevance to the long-term persistence of
gene duplications.

text: 'Diffusiophoretic motion of colloids and macromolecules under salt gradients
exhibits a logarithmic-sensing, i.e. the particle velocity is proportional to
the spatial gradient of the logarithm of the salt concentration, as VDP = DDP∇logc.
Here we explore experimentally the implications of this log-sensing behavior,
on the basis of a hydrogel microfluidic device allowing to build spatially and
temporally controlled gradients. We first demonstrate that the non-linearity of
the salt-taxis leads to a trapping of particles under concentration gradient oscillations
via a rectification of the motion. As an alternative, we make use of the high
sensitivity of diffusiophoretic migration to vanishing salt concentration due
to the log-sensing: in a counter-intuitive way, a vanishing gradient can lead
to measurable velocity provided that the solute concentration is low enough, thus
keeping ∇c/c finite. We show that this leads to a strong segregation of particles
in osmotic shock configuration, resulting from a step change of the salt concentration
at the boundaries. These various phenomena are rationalized on the basis of a
theoretical description for the time-dependent Smoluchowski equation for the colloidal
density.'

text: 'We study theoretically the morphologies of biological tubes affected by various
pathologies. When epithelial cells grow, the negative tension produced by their
division provokes a buckling instability. Several shapes are investigated: varicose,
dilated, sinuous, or sausagelike. They are all found in pathologies of tracheal,
renal tubes, or arteries. The final shape depends crucially on the mechanical
parameters of the tissues: Young''s modulus, wall-to-lumen ratio, homeostatic
pressure. We argue that since tissues must be in quasistatic mechanical equilibrium,
abnormal shapes convey information as to what causes the pathology. We calculate
a phase diagram of tubular instabilities which could be a helpful guide for investigating
the underlying genetic regulation.'

text: EMBRYONIC FLOWER1 (EMF1) is a plant-specific gene crucial to Arabidopsis vegetative
development. Loss of function mutants in the EMF1 gene mimic the phenotype caused
by mutations in Polycomb Group protein (PcG) genes, which encode epigenetic repressors
that regulate many aspects of eukaryotic development. In Arabidopsis, Polycomb
Repressor Complex 2 (PRC2), made of PcG proteins, catalyzes trimethylation of
lysine 27 on histone H3 (H3K27me3) and PRC1-like proteins catalyze H2AK119 ubiquitination.
Despite functional similarity to PcG proteins, EMF1 lacks sequence homology with
known PcG proteins; thus, its role in the PcG mechanism is unclear. To study the
EMF1 functions and its mechanism of action, we performed genome-wide mapping of
EMF1 binding and H3K27me3 modification sites in Arabidopsis seedlings. The EMF1
binding pattern is similar to that of H3K27me3 modification on the chromosomal
and genic level. ChIPOTLe peak finding and clustering analyses both show that
the highly trimethylated genes also have high enrichment levels of EMF1 binding,
termed EMF1_K27 genes. EMF1 interacts with regulatory genes, which are silenced
to allow vegetative growth, and with genes specifying cell fates during growth
and differentiation. H3K27me3 marks not only these genes but also some genes that
are involved in endosperm development and maternal effects. Transcriptome analysis,
coupled with the H3K27me3 pattern, of EMF1_K27 genes in emf1 and PRC2 mutants
showed that EMF1 represses gene activities via diverse mechanisms and plays a
novel role in the PcG mechanism.

text: The regulation of eukaryotic chromatin relies on interactions between many
epigenetic factors, including histone modifications, DNA methylation, and the
incorporation of histone variants. H2A.Z, one of the most conserved but enigmatic
histone variants that is enriched at the transcriptional start sites of genes,
has been implicated in a variety of chromosomal processes. Recently, we reported
a genome-wide anticorrelation between H2A.Z and DNA methylation, an epigenetic
hallmark of heterochromatin that has also been found in the bodies of active genes
in plants and animals. Here, we investigate the basis of this anticorrelation
using a novel h2a.z loss-of-function line in Arabidopsis thaliana. Through genome-wide
bisulfite sequencing, we demonstrate that loss of H2A.Z in Arabidopsis has only
a minor effect on the level or profile of DNA methylation in genes, and we propose
that the global anticorrelation between DNA methylation and H2A.Z is primarily
caused by the exclusion of H2A.Z from methylated DNA. RNA sequencing and genomic
mapping of H2A.Z show that H2A.Z enrichment across gene bodies, rather than at
the TSS, is correlated with lower transcription levels and higher measures of
gene responsiveness. Loss of H2A.Z causes misregulation of many genes that are
disproportionately associated with response to environmental and developmental
stimuli. We propose that H2A.Z deposition in gene bodies promotes variability
in levels and patterns of gene expression, and that a major function of genic
DNA methylation is to exclude H2A.Z from constitutively expressed genes.

text: Accumulating evidence points toward diverse functions for plant chromatin.
Remarkable progress has been made over the last few years in elucidating the mechanisms
for a number of these functions. Activity of the histone demethylase IBM1 accurately
targets DNA methylation to silent repeats and transposable elements, not to genes.
A genetic screen uncovered the surprising role of H2A.Z-containing nucleosomes
in sensing precise differences in ambient temperature and consequent gene regulation.
Precise maintenance of chromosome number is assured by a histone modification
that suppresses inappropriate DNA replication and by centromeric histone H3 regulation
of chromosome segregation. Histones and noncoding RNAs regulate FLOWERING LOCUS
C, the expression of which quantitatively measures the duration of cold exposure,
functioning as memory of winter. These findings are a testament to the power of
using plants to research chromatin organization, and demonstrate examples of how
chromatin functions to achieve biological accuracy, precision, and memory.

text: Motivated by recent experiments on Ba3NiSb2O 9, we investigate possible quantum
spin liquid ground states for spin S=1 Heisenberg models on the triangular lattice.
We use variational Monte Carlo techniques to calculate the energies of microscopic
spin liquid wave functions where spin is represented by three flavors of fermionic
spinon operators. These energies are compared with the energies of various competing
three-sublattice ordered states. Our approach shows that the antiferromagnetic
Heisenberg model with biquadratic term and single-ion anisotropy does not have
a low-temperature spin liquid phase. However, for an SU(3)-invariant model with
sufficiently strong ring-exchange terms, we find a paired chiral quantum spin
liquid with a Fermi surface of deconfined spinons that is stable against all types
of ordering patterns we considered. We discuss the physics of this exotic spin
liquid state in relation to the recent experiment and suggest new ways to test
this scenario.

text: Little is known about the stability of trophic relationships in complex natural
communities over evolutionary timescales. Here, we use sequence data from 18 nuclear
loci to reconstruct and compare the intraspecific histories of major Pleistocene
refugial populations in the Middle East, the Balkans and Iberia in a guild of
four Chalcid parasitoids (Cecidostiba fungosa, Cecidostiba semifascia, Hobbya
stenonota and Mesopolobus amaenus) all attacking Cynipid oak galls. We develop
a likelihood method to numerically estimate models of divergence between three
populations from multilocus data. We investigate the power of this framework on
simulated data, and-using triplet alignments of intronic loci-quantify the support
for all possible divergence relationships between refugial populations in the
four parasitoids. Although an East to West order of population divergence has
highest support in all but one species, we cannot rule out alternative population
tree topologies. Comparing the estimated times of population splits between species,
we find that one species, M. amaenus, has a significantly older history than the
rest of the guild and must have arrived in central Europe at least one glacial
cycle prior to other guild members. This suggests that although all four species
may share a common origin in the East, they expanded westwards into Europe at
different times. © 2012 Blackwell Publishing Ltd.

text: We show that diamagnetic particles can be remotely manipulated by a magnet
by the reversible adsorption of dual-responsive, light-switchable/superparamagnetic
nanoparticles down to their surface. Adsorption occurs upon exposure to UV light,
and can be reversed thermally or by ambient light. The dynamic self-assembly of
thin films of the dual-responsive nanoparticles induces attractive interactions
between diamagnetic particles. We demonstrate that catalytic amounts of the dual-responsive
nanoparticles are sufficient to magnetically guide and deliver the diamagnetic
particles to desired locations, where they can then be released by disassembling
the dynamic layers of superparamagnetic nanoparticles with visible light.

text: Well-defined metallic nanobowls can be prepared by extending the concept of
a protecting group to colloidal synthesis. Magnetic nanoparticles are employed
as “protecting groups” during the galvanic replacement of silver with gold. The
replacement reaction is accompanied by spontantous dissociation of the protecting
groups, leaving behind metallic nanobowls.

text: We propose a logic-based framework for automated reasoning about sequential
programs manipulating singly-linked lists and arrays with unbounded data. We introduce
the logic SLAD, which allows combining shape constraints, written in a fragment
of Separation Logic, with data and size constraints. We address the problem of
checking the entailment between SLAD formulas, which is crucial in performing
pre-post condition reasoning. Although this problem is undecidable in general
for SLAD, we propose a sound and powerful procedure that is able to solve this
problem for a large class of formulas, beyond the capabilities of existing techniques
and tools. We prove that this procedure is complete, i.e., it is actually a decision
procedure for this problem, for an important fragment of SLAD including known
decidable logics. We implemented this procedure and shown its preciseness and
its efficiency on a significant benchmark of formulas.

text: "Energy games belong to a class of turn-based two-player infinite-duration
games played on a weighted directed graph. It is one of the rare and intriguing
combinatorial problems that lie in NP ∩ co−NP, but are not known to be in P. While
the existence of polynomial-time algorithms has been a major open problem for
decades, there is no algorithm that solves any non-trivial subclass in polynomial
time.\r\nIn this paper, we give several results based on the weight structures
of the graph. First, we identify a notion of penalty and present a polynomial-time
algorithm when the penalty is large. Our algorithm is the first polynomial-time
algorithm on a large class of weighted graphs. It includes several counter examples
that show that many previous algorithms, such as value iteration and random facet
algorithms, require at least sub-exponential time. Our main technique is developing
the first non-trivial approximation algorithm and showing how to convert it to
an exact algorithm. Moreover, we show that in a practical case in verification
where weights are clustered around a constant number of values, the energy game
problem can be solved in polynomial time. We also show that the problem is still
as hard as in general when the clique-width is bounded or the graph is strongly
ergodic, suggesting that restricting graph structures need not help."

text: Many infinite state systems can be seen as well-structured transition systems
(WSTS), i.e., systems equipped with a well-quasi-ordering on states that is also
a simulation relation. WSTS are an attractive target for formal analysis because
there exist generic algorithms that decide interesting verification problems for
this class. Among the most popular algorithms are acceleration-based forward analyses
for computing the covering set. Termination of these algorithms can only be guaranteed
for flattable WSTS. Yet, many WSTS of practical interest are not flattable and
the question whether any given WSTS is flattable is itself undecidable. We therefore
propose an analysis that computes the covering set and captures the essence of
acceleration-based algorithms, but sacrifices precision for guaranteed termination.
Our analysis is an abstract interpretation whose abstract domain builds on the
ideal completion of the well-quasi-ordered state space, and a widening operator
that mimics acceleration and controls the loss of precision of the analysis. We
present instances of our framework for various classes of WSTS. Our experience
with a prototype implementation indicates that, despite the inherent precision
loss, our analysis often computes the precise covering set of the analyzed system.

text: Colorectal tumours that are wild type for KRAS are often sensitive to EGFR
blockade, but almost always develop resistance within several months of initiating
therapy. The mechanisms underlying this acquired resistance to anti-EGFR antibodies
are largely unknown. This situation is in marked contrast to that of small-molecule
targeted agents, such as inhibitors of ABL, EGFR, BRAF and MEK, in which mutations
in the genes encoding the protein targets render the tumours resistant to the
effects of the drugs. The simplest hypothesis to account for the development of
resistance to EGFR blockade is that rare cells with KRAS mutations pre-exist at
low levels in tumours with ostensibly wild-type KRAS genes. Although this hypothesis
would seem readily testable, there is no evidence in pre-clinical models to support
it, nor is there data from patients. To test this hypothesis, we determined whether
mutant KRAS DNA could be detected in the circulation of 28 patients receiving
monotherapy with panitumumab, a therapeutic anti-EGFR antibody. We found that
9 out of 24 (38%) patients whose tumours were initially KRAS wild type developed
detectable mutations in KRAS in their sera, three of which developed multiple
different KRAS mutations. The appearance of these mutations was very consistent,
generally occurring between 5 and 6months following treatment. Mathematical modelling
indicated that the mutations were present in expanded subclones before the initiation
of panitumumab treatment. These results suggest that the emergence of KRAS mutations
is a mediator of acquired resistance to EGFR blockade and that these mutations
can be detected in a non-invasive manner. They explain why solid tumours develop
resistance to targeted therapies in a highly reproducible fashion.

text: "Many scenarios in the living world, where individual organisms compete for
winning positions (or resources), have properties of auctions. Here we study the
evolution of bids in biological auctions. For each auction, n individuals are
drawn at random from a population of size N. Each individual makes a bid which
entails a cost. The winner obtains a benefit of a certain value. Costs and benefits
are translated into reproductive success (fitness). Therefore, successful bidding
strategies spread in the population. We compare two types of auctions. In “biological
all-pay auctions”, the costs are the bid for every participating individual. In
“biological second price all-pay auctions”, the cost for everyone other than the
winner is the bid, but the cost for the winner is the second highest bid. Second
price all-pay auctions are generalizations of the “war of attrition” introduced
by Maynard Smith. We study evolutionary dynamics in both types of auctions. We
calculate pairwise invasion plots and evolutionarily stable distributions over
the continuous strategy space. We find that the average bid in second price all-pay
auctions is higher than in all-pay auctions, but the average cost for the winner
is similar in both auctions. In both cases, the average bid is a declining function
of the number of participants, n. The more individuals participate in an auction
the smaller is the chance of winning, and thus expensive bids must be avoided.\r\n"

text: CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. It is generally thought that proximal synapses from
the mossy fibers activate these neurons most efficiently, whereas distal inputs
from the perforant path have a weaker modulatory influence. We used confocally
targeted patch-clamp recording from dendrites and axons to map the activation
of rat CA3 pyramidal neurons at the subcellular level. Our results reveal two
distinct dendritic domains. In the proximal domain, action potentials initiated
in the axon backpropagate actively with large amplitude and fast time course.
In the distal domain, Na+ channel–mediated dendritic spikes are efficiently initiated
by waveforms mimicking synaptic events. CA3 pyramidal neuron dendrites showed
a high Na+-to-K+ conductance density ratio, providing ideal conditions for active
backpropagation and dendritic spike initiation. Dendritic spikes may enhance the
computational power of CA3 pyramidal neurons in the hippocampal network.

text: 'CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. These neurons receive multiple excitatory inputs from
numerous sources. Therefore, the rules of spatiotemporal integration of multiple
synaptic inputs and propagation of action potentials are important to understand
how CA3 neurons contribute to higher brain functions at cellular level. By using
confocally targeted patch-clamp recording techniques, we investigated the biophysical
properties of rat CA3 pyramidal neuron dendrites. We found two distinct dendritic
domains critical for action potential initiation and propagation: In the proximal
domain, action potentials initiated in the axon backpropagate actively with large
amplitude and fast time course. In the distal domain, Na+-channel mediated dendritic
spikes are efficiently evoked by local dendritic depolarization or waveforms mimicking
synaptic events. These findings can be explained by a high Na+-to-K+ conductance
density ratio of CA3 pyramidal neuron dendrites. The results challenge the prevailing
view that proximal mossy fiber inputs activate CA3 pyramidal neurons more efficiently
than distal perforant inputs by showing that the distal synapses trigger a different
form of activity represented by dendritic spikes. The high probability of dendritic
spike initiation in the distal area may enhance the computational power of CA3
pyramidal neurons in the hippocampal network. '

text: Visualizing and analyzing shape changes at various scales, ranging from single
molecules to whole organisms, are essential for understanding complex morphogenetic
processes, such as early embryonic development. Embryo morphogenesis relies on
the interplay between different tissues, the properties of which are again determined
by the interaction between their constituent cells. Cell interactions, on the
other hand, are controlled by various molecules, such as signaling and adhesion
molecules, which in order to exert their functions need to be spatiotemporally
organized within and between the interacting cells. In this review, we will focus
on the role of cell adhesion functioning at different scales to organize cell,
tissue and embryo morphogenesis. We will specifically ask how the subcellular
distribution of adhesion molecules controls the formation of cell-cell contacts,
how cell-cell contacts determine tissue shape, and how tissue interactions regulate
embryo morphogenesis.

text: The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes
DNA demethylation before fertilization, but the targeting preferences, mechanism,
and biological significance of this process remain unclear. Here, we show that
active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for
all of the demethylation in the central cell and preferentially targets small,
AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative
cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation
of similar sequences, and lack of DEMETER in vegetative cells causes reduced small
RNA–directed DNA methylation of transposons in sperm. Our results demonstrate
that demethylation in companion cells reinforces transposon methylation in plant
gametes and likely contributes to stable silencing of transposable elements across
generations.

text: First we note that the best polynomial approximation to vertical bar x vertical
bar on the set, which consists of an interval on the positive half-axis and a
point on the negative half-axis, can be given by means of the classical Chebyshev
polynomials. Then we explore the cases when a solution of the related problem
on two intervals can be given in elementary functions.

text: We introduce the idea of using an explicit triangle mesh to track the air/fluid
interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial
surface mesh is created, this mesh is carried forward in time using nearby particle
velocities to advect the mesh vertices. The mesh connectivity remains mostly unchanged
across time-steps; it is only modified locally for topology change events or for
the improvement of triangle quality. In order to ensure that the surface mesh
does not diverge from the underlying particle simulation, we periodically project
the mesh surface onto an implicit surface defined by the physics simulation. The
mesh surface gives us several advantages over previous SPH surface tracking techniques.
We demonstrate a new method for surface tension calculations that clearly outperforms
the state of the art in SPH surface tension for computer graphics. We also demonstrate
a method for tracking detailed surface information (like colors) that is less
susceptible to numerical diffusion than competing techniques. Finally, our temporally-coherent
surface mesh allows us to simulate high-resolution surface wave dynamics without
being limited by the particle resolution of the SPH simulation.

text: "When searching for characteristic subpatterns in potentially noisy graph
data, it appears self-evident that having multiple observations would be better
than having just one. However, it turns out that the inconsistencies introduced
when different graph instances have different edge sets pose a serious challenge.
In this work we address this challenge for the problem of finding maximum weighted
cliques.\r\n We introduce the concept of most persistent soft-clique. This
is subset of vertices, that 1) is almost fully or at least densely connected,
2) occurs in all or almost all graph instances, and 3) has the maximum weight.
We present a measure of clique-ness, that essentially counts the number of edge
missing to make a subset of vertices into a clique. With this measure, we show
that the problem of finding the most persistent soft-clique problem can be cast
either as: a) a max-min two person game optimization problem, or b) a min-min
soft margin optimization problem. Both formulations lead to the same solution
when using a partial Lagrangian method to solve the optimization problems. By
experiments on synthetic data and on real social network data, we show that the
proposed method is able to reliably find soft cliques in graph data, even if that
is distorted by random noise or unreliable observations."

text: Generalized van der Corput sequences are onedimensional, infinite sequences
in the unit interval. They are generated from permutations in integer base b and
are the building blocks of the multi-dimensional Halton sequences. Motivated by
recent progress of Atanassov on the uniform distribution behavior of Halton sequences,
we study, among others, permutations of the form P(i) = ai (mod b) for coprime
integers a and b. We show that multipliers a that either divide b - 1 or b + 1
generate van der Corput sequences with weak distribution properties. We give explicit
lower bounds for the asymptotic distribution behavior of these sequences and relate
them to sequences generated from the identity permutation in smaller bases, which
are, due to Faure, the weakest distributed generalized van der Corput sequences.

text: We perform numerical simulations to study self-assembly of nanoparticles mediated
by an elastic planar surface. We show how the nontrivial elastic response to deformations
of these surfaces leads to anisotropic interactions between the particles resulting
in aggregates having different geometrical features. The morphology of the patterns
can be controlled by the mechanical properties of the surface and the strength
of the particle adhesion. We use simple scaling arguments to understand the formation
of the different structures, and we show how the adhering particles can cause
the underlying elastic substrate to wrinkle if two of its opposite edges are clamped.
Finally, we discuss the implications of our results and suggest how elastic surfaces
could be used in nanofabrication.

text: We present experimentally derived potential curves 1?and spin-orbit interaction
functions for the strongly perturbed AΣu+ 3?and bΠu states of the cesium dimer.
The results are based on data from several sources. Laser-induced fluorescence
Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire
Aimé Cotton primarily to study the XΣg+ state. More recent work at Tsinghua University
provides information from moderate 3?resolution spectroscopy on the lowest levels
of the bΠ0u± state as well as additional high-resolution data. From Innsbruck
University, we have precision data obtained with cold Cs2 molecules. Recent data
from Temple University was obtained using the optical-optical double resonance
polarization spectroscopy technique, and finally, a group at the University of
Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used
analytic potentials (the expanded Morse oscillator form) with both finite-difference
(FD) coupled-channel and discrete variable representation (DVR) calculations of
the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained
and compared with ab initio results from Temple and Moscow State universities.

text: We produce an ultracold and dense sample of rovibronic ground state Cs 2 molecules
close to the regime of quantum degeneracy, in a single hyperfine level, in the
presence of an optical lattice. The molecules are individually trapped, in the
motional ground state of an optical lattice well, with a lifetime of 8 s. For
preparation, we start with a zero-temperature atomic Mott-insulator state with
optimized double-site occupancy and efficiently associate weakly-bound dimer molecules
on a Feshbach resonance. Despite extremely weak Franck-Condon wavefunction overlap,
the molecules are subsequently transferred with >50% efficiency to the rovibronic
ground state by a stimulated four-photon process. Our results present a crucial
step towards the generation of Bose-Einstein condensates of ground-state molecules
and, when suitably generalized to polar heteronuclear molecules such as RbCs,
the realization of dipolar many-body quantum-gas phases in periodic potentials.

text: The present paper aims at finding optimal parameters for trapping of Cs 2
molecules in optical lattices, with the perspective of creating a quantum degenerate
gas of ground-state molecules. We have calculated dynamic polarizabilities of
Cs 2 molecules subject to an oscillating electric field, using accurate potential
curves and electronic transition dipole moments. We show that for some particular
wavelengths of the optical lattice, called "magic wavelengths", the
polarizability of the ground-state molecules is equal to the one of a Feshbach
molecule. As the creation of the sample of ground-state molecules relies on an
adiabatic population transfer from weakly-bound molecules created on a Feshbach
resonance, such a coincidence ensures that both the initial and final states are
favorably trapped by the lattice light, allowing optimized transfer in agreement
with the experimental observation.

text: We demonstrate the temporal Talbot effect for trapped matter waves using ultracold
atoms in an optical lattice. We investigate the phase evolution of an array of
essentially non-interacting matter waves and observe matter-wave collapse and
revival in the form of a Talbot interference pattern. By using long expansion
times, we image momentum space with sub-recoil resolution, allowing us to observe
fractional Talbot fringes up to tenth order.

text: We investigate local three-body correlations for bosonic particles in three
dimensions and one dimension as a function of the interaction strength. The three-body
correlation function g(3) is determined by measuring the three-body recombination
rate in an ultracold gas of Cs atoms. In three dimensions, we measure the dependence
of g(3) on the gas parameter in a BEC, finding good agreement with the theoretical
prediction accounting for beyond-mean-field effects. In one dimension, we observe
a reduction of g( 3) by several orders of magnitude upon increasing interactions
from the weakly interacting BEC to the strongly interacting Tonks-Girardeau regime,
in good agreement with predictions from the Lieb-Liniger model for all strengths
of interaction.

text: Nuclear pore complexes (NPCs) assemble at the end of mitosis during nuclear
envelope (NE) reformation and into an intact NE as cells progress through interphase.
Although recent studies have shown that NPC formation occurs by two different
molecular mechanisms at two distinct cell cycle stages, little is known about
the molecular players that mediate the fusion of the outer and inner nuclear membranes
to form pores. In this paper, we provide evidence that the transmembrane nucleoporin
(Nup), POM121, but not the Nup107–160 complex, is present at new pore assembly
sites at a time that coincides with inner nuclear membrane (INM) and outer nuclear
membrane (ONM) fusion. Overexpression of POM121 resulted in juxtaposition of the
INM and ONM. Additionally, Sun1, an INM protein that is known to interact with
the cytoskeleton, was specifically required for interphase assembly and localized
with POM121 at forming pores. We propose a model in which POM121 and Sun1 interact
transiently to promote early steps of interphase NPC assembly.

text: As the gatekeepers of the eukaryotic cell nucleus, nuclear pore complexes
(NPCs) mediate all molecular trafficking between the nucleoplasm and the cytoplasm.
In recent years, transport-independent functions of NPC components, nucleoporins,
have been identified including roles in chromatin organization and gene regulation.
Here, we summarize our current view of the NPC as a dynamic hub for the integration
of chromatin regulation and nuclear trafficking and discuss the functional interplay
between nucleoporins and the nuclear genome.

text: Eukaryotic cell function depends on the physical separation of nucleoplasmic
and cytoplasmic components by the nuclear envelope (NE). Molecular communication
between the two compartments involves active, signal-mediated trafficking, a function
that is exclusively performed by nuclear pore complexes (NPCs). The individual
NPC components and the mechanisms that are involved in nuclear trafficking are
well documented and have become textbook knowledge. However, in addition to their
roles as nuclear gatekeepers, NPC components-nucleoporins-have been shown to have
critical roles in chromatin organization and gene regulation. These findings have
sparked new enthusiasm to study the roles of this multiprotein complex in nuclear
organization and explore novel functions that in some cases appear to go beyond
a role in transport. Here, we discuss our present view of NPC biogenesis, which
is tightly linked to proper cell cycle progression and cell differentiation. In
addition, we summarize new data suggesting that NPCs represent dynamic hubs for
the integration of gene regulation and nuclear transport processes.

text: Particle beams are important tools for probing atomic and molecular interactions.
Here we demonstrate that particle beams also offer a unique opportunity to investigate
interactions in macroscopic systems, such as granular media. Motivated by recent
experiments on streams of grains that exhibit liquid-like breakup into droplets,
we use molecular dynamics simulations to investigate the evolution of a dense
stream of macroscopic spheres accelerating out of an opening at the bottom of
a reservoir. We show how nanoscale details associated with energy dissipation
during collisions modify the stream\'s macroscopic behavior. We find that inelastic
collisions collimate the stream, while the presence of short-range attractive
interactions drives structure formation. Parameterizing the collision dynamics
by the coefficient of restitution (i.e., the ratio of relative velocities before
and after impact) and the strength of the cohesive interaction, we map out a spectrum
of behaviors that ranges from gaslike jets in which all grains drift apart to
liquid-like streams that break into large droplets containing hundreds of grains.
We also find a new, intermediate regime in which small aggregates form by capture
from the gas phase, similar to what can be observed in molecular beams. Our results
show that nearly all aspects of stream behavior are closely related to the velocity
gradient associated with vertical free fall. Led by this observation, we propose
a simple energy balance model to explain the droplet formation process. The qualitative
as well as many quantitative features of the simulations and the model compare
well with available experimental data and provide a first quantitative measure
of the role of attractions in freely cooling granular streams.

text: Given only the URL of a Web page, can we identify its topic? We study this
problem in detail by exploring a large number of different feature sets and algorithms
on several datasets. We also show that the inherent overlap between topics and
the sparsity of the information in URLs makes this a very challenging problem.
Web page classification without a page’s content is desirable when the content
is not available at all, when a classification is needed before obtaining the
content, or when classification speed is of utmost importance. For our experiments
we used five different corpora comprising a total of about 3 million (URL, classification)
pairs. We evaluated several techniques for feature generation and classification
algorithms. The individual binary classifiers were then combined via boosting
into metabinary classifiers. We achieve typical F-measure values between 80 and
85, and a typical precision of around 86. The precision can be pushed further
over 90 while maintaining a typical level of recall between 30 and 40.

text: "The design of truthful auctions that approximate the optimal expected revenue
is a central problem in algorithmic mechanism design. 30 years after Myerson’s
characterization of Bayesian optimal auctions in single-parameter domains [8],
characterizing but also providing efficient mechanisms for multi-parameter domains
still remains a very important unsolved problem. Our work improves upon recent
results in this area, introducing new techniques for tackling the problem, while
also combining and extending recently introduced tools.\r\n\r\nIn particular we
give the first approximation algorithms for Bayesian auctions with multiple heterogeneous
items when bidders have additive valuations, budget constraints and general matroid
feasibility constraints."

text: Auctions are widely used on the Web. Applications range from internet advertising
to platforms such as eBay. In most of these applications the auctions in use are
single/multi-item auctions with unit demand. The main drawback of standard mechanisms
for this type of auctions, such as VCG and GSP, is the limited expressiveness
that they offer to the bidders. The General Auction Mechanism (GAM) of [1] is
taking a first step towards addressing the problem of limited expressiveness by
computing a bidder optimal, envy free outcome for linear utility functions with
identical slopes and a single discontinuity per bidder-item pair. We show that
in many practical situations this does not suffice to adequately model the preferences
of the bidders, and we overcome this problem by presenting the first mechanism
for piece-wise linear utility functions with non-identical slopes and multiple
discontinuities. Our mechanism runs in polynomial time. Like GAM it is incentive
compatible for inputs that fulfill a certain non-degeneracy requirement, but our
requirement is more general than the requirement of GAM. For discontinuous utility
functions that are non-degenerate as well as for continuous utility functions
the outcome of our mechanism is a competitive equilibrium. We also show how our
mechanism can be used to compute approximately bidder optimal, envy free outcomes
for a general class of continuous utility functions via piece-wise linear approximation.
Finally, we prove hardness results for even more expressive settings.

text: Temperature data from three Automatic Weather Stations and twelve Temperature
Loggers are used to investigate the spatiotemporal variability of temperature
over a glacier, its main atmospheric controls, the suitability of extrapolation
techniques and their effect on melt modeling. We use data collected on Juncal
Norte Glacier, central Chile, during one ablation season. We examine temporal
and spatial variability in lapse rates (LRs), together with alternative statistical
interpolation methods. The main control over the glacier thermal regime is the
development of a katabatic boundary layer (KBL). Katabatic wind occurs at night
and in the morning and is eroded in the afternoon. LRs reveal strong diurnal variability,
with steeper LRs during the day when the katabatic wind weakens and shallower
LRs during the night and morning. We suggest that temporally variable LRs should
be used to account for the observed change. They tend to be steeper than equivalent
constant LRs, and therefore result in a reduction in simulated melt compared to
use of constant LRs when extrapolating from lower to higher elevations. In addition
to the temporal variability, the temperature-elevation relationship varies also
in space. Differences are evident between local LRs and including such variability
in melt modeling affects melt simulations. Extrapolation methods based on the
spatial variability of the observations after removal of the elevation trend,
such as Inverse Distance Weighting or Kriging, do not seem necessary for simulations
of gridded temperature data over a glacier.

text: Physically based hydrological models describe natural processes more accurately
than conceptual models but require extensive data sets to produce accurate results.
To identify the value of different data sets for improving the performance of
the distributed hydrological model TOPKAPI we combine a multivariable validation
technique with Monte Carlo simulations. The study is carried out in the snow and
ice-dominated Rhonegletscher basin, as these types of mountainous basins are generally
the most critical with respect to data availability and sensitivity to climate
fluctuations. Each observational data set is used individually and in combination
with the other data sets to determine a subset of best parameter combinations
out of 10,000 Monte Carlos runs performed with randomly generated parameter sets.
We validate model results against discharge, glacier mass balance, and satellite
snow cover images for a 14 year time period (1994–2007). While the use of all
data sets combined provides the best overall model performance (defined by the
concurrent best agreement of simulated discharge, snow cover and mass balance
with their respective measurements), the use of one or two variables for constraining
the model results in poorer performance. Using only one data set for constraining
the model glacier mass balance proved to be the most efficient observation leading
to the best overall model performance. Our main result is that a combination of
discharge and satellite snow cover images is best for improving model performance,
since the volumetric information of discharge data and the spatial information
of snow cover images are complementary.

text: We explore the robustness and transferability of parameterizations of cloud
radiative forcing used in glacier melt models at two sites in the Swiss Alps.
We also look at the rationale behind some of the most commonly used approaches,
and explore the relationship between cloud transmittance and several standard
meteorological variables. The 2 m air-temperature diurnal range is the best predictor
of variations in cloud transmittance. However, linear and exponential parameterizations
can only explain 30–50% of the observed variance in computed cloud transmittance
factors. We examine the impact of modelled cloud transmittance factors on both
solar radiation and ablation rates computed with an enhanced temperature-index
model. The melt model performance decreases when modelled radiation is used, the
reduction being due to an underestimation of incoming solar radiation on clear-sky
days. The model works well under overcast conditions. We also seek alternatives
to the use of in situ ground data. However, outputs from an atmospheric model
(2.2 km horizontal resolution) do not seem to provide an alternative to the parameterizations
of cloud radiative forcing based on observations of air temperature at glacier
automatic weather stations. Conversely, the correct definition of overcast conditions
is important.

text: Streamflow is a hydrological variable measured at a defined river cross-section;
it spatially integrates the runoff generating processes in the contributing watershed,
including precipitation and air temperature. Trends in streamflow are progressive
changes in the time series of streamflow that can be detected with statistical
methods and their statistical significance can be assessed. Mountainous regions
are particularly vulnerable to streamflow change because of their high specific
runoff and the sensitivity to the distribution of precipitation and air temperature,
and the processes of snow accumulation and melt.

text: Recent experiments have shown that motion detection in Drosophila starts with
splitting the visual input into two parallel channels encoding brightness increments
(ON) or decrements (OFF). This suggests the existence of either two (ON-ON, OFF-OFF)
or four (for all pairwise interactions) separate motion detectors. To decide between
these possibilities, we stimulated flies using sequences of ON and OFF brightness
pulses while recording from motion-sensitive tangential cells. We found direction-selective
responses to sequences of same sign (ON-ON, OFF-OFF), but not of opposite sign
(ON-OFF, OFF-ON), refuting the existence of four separate detectors. Based on
further measurements, we propose a model that reproduces a variety of additional
experimental data sets, including ones that were previously interpreted as support
for four separate detectors. Our experiments and the derived model mark an important
step in guiding further dissection of the fly motion detection circuit.

text: We propose a general conjecture for the mixed Hodge polynomial of the generic
character varieties of representations of the fundamental group of a Riemann surface
of genus g to GLn(C) with fixed generic semisimple conjugacy classes at k punctures.
This conjecture generalizes the Cauchy identity for Macdonald polynomials and
is a common generalization of two formulas that we prove in this paper. The first
is a formula for the E-polynomial of these character varieties which we obtain
using the character table of GLn(Fq). We use this formula to compute the Euler
characteristic of character varieties. The second formula gives the Poincaré polynomial
of certain associated quiver varieties which we obtain using the character table
of gln(Fq). In the last main result we prove that the Poincaré polynomials of
the quiver varieties equal certain multiplicities in the tensor product of irreducible
characters of GLn(Fq). As a consequence we find a curious connection between Kac-Moody
algebras associated with comet-shaped, and typically wild, quivers and the representation
theory of GLn(Fq).

text: The emergence of differences in the arrangement of cells is the first step
towards the establishment of many organs. Understanding this process is limited
by the lack of systematic characterization of epithelial organisation. Here we
apply network theory at the scale of individual cells to uncover patterns in cell-to-cell
contacts that govern epithelial organisation. We provide an objective characterisation
of epithelia using network representation, where cells are nodes and cell contacts
are links. The features of individual cells, together with attributes of the cellular
network, produce a defining signature that distinguishes epithelia from different
organs, species, developmental stages and genetic conditions. The approach permits
characterization, quantification and classification of normal and perturbed epithelia,
and establishes a framework for understanding molecular mechanisms that underpin
the architecture of complex tissues.

text: Morphogens, such as Decapentaplegic (Dpp) in the fly imaginal discs, form
graded concentration profiles that control patterning and growth of developing
organs. In the imaginal discs, proliferative growth is homogeneous in space, posing
the conundrum of how morphogen concentration gradients could control position-independent
growth. To understand the mechanism of proliferation control by the Dpp gradient,
we quantified Dpp concentration and signaling levels during wing disc growth.
Both Dpp concentration and signaling gradients scale with tissue size during development.
On average, cells divide when Dpp signaling levels have increased by 50%. Our
observations are consistent with a growth control mechanism based on temporal
changes of cellular morphogen signaling levels. For a scaling gradient, this mechanism
generates position-independent growth rates.

text: Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal
leads is reported. The spin selectivity arises from an interplay of the orbital
effect of the magnetic field with the strong spin-orbit interaction present in
the valence band of the semiconductor. We demonstrate both experimentally and
theoretically that spin-selective tunneling in semiconductor nanostructures can
be achieved without the use of ferromagnetic contacts. The reported effect, which
relies on mixing the light and heavy holes, should be observable in a broad class
of quantum-dot systems formed in semiconductors with a degenerate valence band.

text: Superconducting circuits have been successfully established as systems to
prepare and investigate microwave light fields at the quantum level. In contrast
to optical experiments where light is detected using photon counters, microwaves
are usually measured with well developed linear amplifiers. This makes measurements
of correlation functions - one of the important tools in optics - harder to achieve
because they traditionally rely on photon counters and beam splitters. Here, we
demonstrate a system where we can prepare on demand single microwave photons in
a cavity and detect them at the two outputs of the cavity using linear amplifiers.
Together with efficient data processing, this allows us to measure different observables
of the cavity photons, including the first-order correlation function. Using these
techniques we demonstrate cooling of a thermal background field in the cavity.

text: A wide range of experiments studying microwave photons localized in superconducting
cavities have made important contributions to our understanding of the quantum
properties of radiation. Propagating microwave photons, however, have so far been
studied much less intensely. Here we present measurements in which we reconstruct
the quantum state of itinerant single photon Fock states and their superposition
with the vacuum by analyzing moments of the measured amplitude distribution up
to fourth order. Using linear amplifiers and quadrature amplitude detectors, we
have developed efficient methods to separate the detected single photon signal
from the noise added by the amplifier. From our measurement data we have also
reconstructed the corresponding Wigner function.

text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

text: At optical frequencies the radiation produced by a source, such as a laser,
a black body or a single-photon emitter, is frequently characterized by analysing
the temporal correlations of emitted photons using single-photon counters. At
microwave frequencies, however, there are no efficient single-photon counters
yet. Instead, well-developed linear amplifiers allow for efficient measurement
of the amplitude of an electromagnetic field. Here, we demonstrate first- and
second-order correlation function measurements of a pulsed microwave-frequency
single-photon source integrated on the same chip with a 50/50 beam splitter followed
by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon
coherence in first-order and photon antibunching in second-order correlation function
measurements of the propagating fields.
