text: Correlative microscopy incorporates the specificity of fluorescent protein
labeling into high-resolution electron micrographs. Several approaches exist for
correlative microscopy, most of which have used the green fluorescent protein
(GFP) as the label for light microscopy. Here we use chemical tagging and synthetic
fluorophores instead, in order to achieve protein-specific labeling, and to perform
multicolor imaging. We show that synthetic fluorophores preserve their post-embedding
fluorescence in the presence of uranyl acetate. Post-embedding fluorescence is
of such quality that the specimen can be prepared with identical protocols for
scanning electron microscopy (SEM) and transmission electron microscopy (TEM);
this is particularly valuable when singular or otherwise difficult samples are
examined. We show that synthetic fluorophores give bright, well-resolved signals
in super-resolution light microscopy, enabling us to superimpose light microscopic
images with a precision of up to 25 nm in the x–y plane on electron micrographs.
To exemplify the preservation quality of our new method we visualize the molecular
arrangement of cadherins in adherens junctions of mouse epithelial cells.

text: Fractionation of isotopes among distinct molecules or phases is a quantum
effect which is often exploited to obtain insights on reaction mechanisms, biochemical,
geochemical, and atmospheric phenomena. Accurate evaluation of isotope ratios
in atomistic simulations is challenging, because one needs to perform a thermodynamic
integration with respect to the isotope mass, along with time-consuming path integral
calculations. By re-formulating the problem as a particle exchange in the ring
polymer partition function, we derive new estimators giving direct access to the
differential partitioning of isotopes, which can simplify the calculations by
avoiding thermodynamic integration. We demonstrate the efficiency of these estimators
by applying them to investigate the isotope fractionation ratios in the gas-phase
Zundel cation, and in a few simple hydrocarbons.

text: It is well known that ultrasonic vibration can soften metals, and this phenomenon
has been widely exploited in industrial applications concerning metal forming
and bonding. Recent experiments show that the simultaneous application of oscillatory
stresses from audible to ultrasonic frequency ranges can lead to not only softening
but also significant dislocation annihilation and subgrain formation in metal
samples from the nano- to macro-size range. These findings indicate that the existing
understanding of ultrasound softening – that the vibrations either impose additional
stress waves to augment the quasi-static applied load, or cause heating of the
metal, whereas the metal’s intrinsic deformation resistance or mechanism remains
unaltered – is far from complete. To understand the softening and the associated
enhanced subgrain formation and dislocation annihilation, a new simulator based
on the dynamics of dislocation-density functions is employed. This new simulator
considers the flux, production and annihilation, as well as the Taylor and elastic
interactions between dislocation densities. Softening during vibrations as well
as enhanced cell formation is predicted. The simulations reveal the main mechanism
for subcell formation under oscillatory loadings to be the enhanced elimination
of statistically stored dislocations (SSDs) by the oscillatory stress, leaving
behind geometrically necessary dislocations with low Schmid factors which then
form the subgrain walls. The oscillatory stress helps the depletion of the SSDs,
because the chance for them to meet up and annihilate is increased with reversals
of dislocation motions. This is the first simulation effort to successfully predict
the cell formation phenomenon under vibratory loadings.

text: The distribution of Coulomb blockade peak heights as a function of magnetic
field is investigated experimentally in a Ge-Si nanowire quantum dot. Strong spin-orbit
coupling in this hole-gas system leads to antilocalization of Coulomb blockade
peaks, consistent with theory. In particular, the peak height distribution has
its maximum away from zero at zero magnetic field, with an average that decreases
with increasing field. Magnetoconductance in the open-wire regime places a bound
on the spin-orbit length (lso < 20 nm), consistent with values extracted in the
Coulomb blockade regime (lso < 25 nm).

text: The fitness effects of symbionts on their hosts can be context-dependent,
with usually benign symbionts causing detrimental effects when their hosts are
stressed, or typically parasitic symbionts providing protection towards their
hosts (e.g. against pathogen infection). Here, we studied the novel association
between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
formicarum for potential costs and benefits. We tested ants with different Laboulbenia
levels for their survival and immunity under resource limitation and exposure
to the obligate killing entomopathogen Metarhizium brunneum. While survival of
L. neglectus workers under starvation was significantly decreased with increasing
Laboulbenia levels, host survival under Metarhizium exposure increased with higher
levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
which seems to be driven mechanistically by both improved sanitary behaviours
and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
longer self-grooming and elevated expression of immune genes relevant for wound
repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
Laboulbenia formicarum weakens its ant host by either direct resource exploitation
or the costs of an upregulated behavioural and immunological response, which,
however, provides a prophylactic protection upon later exposure to pathogens.

text: Understanding the effects of sex and migration on adaptation to novel environments
remains a key problem in evolutionary biology. Using a single-cell alga Chlamydomonas
reinhardtii, we investigated how sex and migration affected rates of evolutionary
rescue in a sink environment, and subsequent changes in fitness following evolutionary
rescue. We show that sex and migration affect both the rate of evolutionary rescue
and subsequent adaptation. However, their combined effects change as the populations
adapt to a sink habitat. Both sex and migration independently increased rates
of evolutionary rescue, but the effect of sex on subsequent fitness improvements,
following initial rescue, changed with migration, as sex was beneficial in the
absence of migration but constraining adaptation when combined with migration.
These results suggest that sex and migration are beneficial during the initial
stages of adaptation, but can become detrimental as the population adapts to its
environment.

text: Redundancies and correlations in the responses of sensory neurons may seem
to waste neural resources, but they can also carry cues about structured stimuli
and may help the brain to correct for response errors. To investigate the effect
of stimulus structure on redundancy in retina, we measured simultaneous responses
from populations of retinal ganglion cells presented with natural and artificial
stimuli that varied greatly in correlation structure; these stimuli and recordings
are publicly available online. Responding to spatio-temporally structured stimuli
such as natural movies, pairs of ganglion cells were modestly more correlated
than in response to white noise checkerboards, but they were much less correlated
than predicted by a non-adapting functional model of retinal response. Meanwhile,
responding to stimuli with purely spatial correlations, pairs of ganglion cells
showed increased correlations consistent with a static, non-adapting receptive
field and nonlinearity. We found that in response to spatio-temporally correlated
stimuli, ganglion cells had faster temporal kernels and tended to have stronger
surrounds. These properties of individual cells, along with gain changes that
opposed changes in effective contrast at the ganglion cell input, largely explained
the pattern of pairwise correlations across stimuli where receptive field measurements
were possible.

text: Relaxation and dephasing of hole spins are measured in a gate-defined Ge/Si
nanowire double quantum dot using a fast pulsed-gate method and dispersive readout.
An inhomogeneous dephasing time T2* ∼ 0.18 μs exceeds corresponding measurements
in III-V semiconductors by more than an order of magnitude, as expected for predominately
nuclear-spin-free materials. Dephasing is observed to be exponential in time,
indicating the presence of a broadband noise source, rather than Gaussian, previously
seen in systems with nuclear-spin-dominated dephasing.

text: 'We explore the relationship between polar and RM codes and we describe a
coding scheme which improves upon the performance of the standard polar code at
practical block lengths. Our starting point is the experimental observation that
RM codes have a smaller error probability than polar codes under MAP decoding.
This motivates us to introduce a family of codes that “interpolates” between RM
and polar codes, call this family C inter = {C α : α ∈ [0, 1j}, where C α|α=1
is the original polar code, and C α|α=0 is an RM code. Based on numerical observations,
we remark that the error probability under MAP decoding is an increasing function
of α. MAP decoding has in general exponential complexity, but empirically the
performance of polar codes at finite block lengths is boosted by moving along
the family Cinter even under low-complexity decoding schemes such as, for instance,
belief propagation or successive cancellation list decoder. We demonstrate the
performance gain via numerical simulations for transmission over the erasure channel
as well as the Gaussian channel.'

text: We describe coding techniques that achieve the capacity of a discrete memoryless
asymmetric channel. To do so, we discuss how recent advances in coding for symmetric
channels yield more efficient solutions also for the asymmetric case. In more
detail, we consider three basic approaches. The first one is Gallager's scheme
that concatenates a linear code with a non-linear mapper, in order to bias the
input distribution. We explicitly show that both polar codes and spatially coupled
codes can be employed in this scenario. Further, we derive a scaling law between
the gap to capacity, the cardinality of channel input and output alphabets, and
the required size of the mapper. The second one is an integrated approach in which
the coding scheme is used both for source coding, in order to create codewords
with the capacity-achieving distribution, and for channel coding, in order to
provide error protection. Such a technique has been recently introduced by Honda
and Yamamoto in the context of polar codes, and we show how to apply it also to
the design of sparse graph codes. The third approach is based on an idea due to
Böcherer and Mathar and separates completely the two tasks of source coding and
channel coding by “chaining” together several codewords. We prove that we can
combine any suitable source code with any suitable channel code in order to provide
optimal schemes for asymmetric channels. In particular, polar codes and spatially
coupled codes fulfill the required conditions.

text: With the aim of extending the coverage and improving the performance of impulse
radio ultra-wideband (UWB) systems, this paper focuses on developing a novel single
differential encoded decode and forward (DF) non-cooperative relaying scheme (NCR).
To favor simple receiver structures, differential noncoherent detection is employed
which enables effective energy capture without any channel estimation. Putting
emphasis on the general case of multi-hop relaying, we illustrate an original
algorithm for the joint power allocation and path selection (JPAPS), minimizing
an approximate expression of the overall bit error rate (BER). In particular,
after deriving a closed-form power allocation strategy, the optimal path selection
is reduced to a shortest path problem on a connected graph, which can be solved
without any topology information with complexity O(N 3 ), N being the number of
available relays of the network. An approximate scheme is also presented, which
reduces the complexity to O(N 2 ) while showing a negligible performance loss,
and for benchmarking purposes, an exhaustive-search based multi-hop DF cooperative
strategy is derived. Simulation results for various network setups corroborate
the effectiveness of the proposed low-complexity JPAPS algorithm, which favorably
compares to existing AF and DF relaying methods.

text: This monograph presents a short course in computational geometry and topology.
In the first part the book covers Voronoi diagrams and Delaunay triangulations,
then it presents the theory of alpha complexes which play a crucial role in biology.
The central part of the book is the homology theory and their computation, including
the theory of persistence which is indispensable for applications, e.g. shape
reconstruction. The target audience comprises researchers and practitioners in
mathematics, biology, neuroscience and computer science, but the book may also
be beneficial to graduate students of these fields.

text: Spin and orbital quantum numbers play a key role in the physics of Mott insulators,
but in most systems they are connected only indirectly—via the Pauli exclusion
principle and the Coulomb interaction. Iridium-based oxides (iridates) introduce
strong spin–orbit coupling directly, such that these numbers become entwined together
and the Mott physics attains a strong orbital character. In the layered honeycomb
iridates this is thought to generate highly spin–anisotropic magnetic interactions,
coupling the spin to a given spatial direction of exchange and leading to strongly
frustrated magnetism. Here we report a new iridate structure that has the same
local connectivity as the layered honeycomb and exhibits striking evidence for
highly spin–anisotropic exchange. The basic structural units of this material
suggest that a new family of three-dimensional structures could exist, the ‘harmonic
honeycomb’ iridates, of which the present compound is the first example.

text: We investigate the structural and magnetic properties of two molecule-based
magnets synthesized from the same starting components. Their different structural
motifs promote contrasting exchange pathways and consequently lead to markedly
different magnetic ground states. Through examination of their structural and
magnetic properties we show that [Cu(pyz)(H2O)(gly)2](ClO4)2 may be considered
a quasi-one-dimensional quantum Heisenberg antiferromagnet whereas the related
compound [Cu(pyz)(gly)](ClO4), which is formed from dimers of antiferromagnetically
interacting Cu2+ spins, remains disordered down to at least 0.03 K in zero field
but shows a field-temperature phase diagram reminiscent of that seen in materials
showing a Bose-Einstein condensation of magnons.

text: Photoinduced electron transfer (PET), which causes pH-dependent quenching
of fluorescent dyes, is more effectively introduced by phenolic groups than by
amino groups which have been much more commonly used so far. That is demonstrated
by fluorescence measurements involving several classes of fluorophores. Electrochemical
measurements show that PET in several amino-modified dyes is thermodynamically
favorable, even though it was not experimentally found, underlining the importance
of kinetic aspects to the process. Consequently, the attachment of phenolic groups
allows for fast and simple preparation of a wide selection of fluorescent pH-probes
with tailor-made spectral properties, sensitive ranges, and individual advantages,
so that a large number of applications can be realized. Fluorophores carrying
phenolic groups may also be used for sensing analytes other than pH or molecular
switching and signaling.

text: Several problems arise at the O2 (positive) electrode in the Li-air battery,
including solvent/electrode decomposition and electrode passivation by insulating
Li2O2. Progress partially depends on exploring the basic electrochemistry of O2
reduction. Here we describe the effect of complexing-cations on the electrochemical
reduction of O2 in DMSO in the presence and absence of a Li salt. The solubility
of alkaline peroxides in DMSO is enhanced by the complexing-cations, consistent
with their strong interaction with reduced O2. The complexing-cations also increase
the rate of the 1-electron O2 reduction to O2•– by up to six-fold (k° = 2.4 ×10–3
to 1.5 × 10–2 cm s–1) whether or not Li+ ions are present. In the absence of Li+,
the complexing-cations also promote the reduction of O2•– to O22–. In the presence
of Li+ and complexing-cations, and despite the interaction of the reduced O2 with
the latter, SERS confirms that the product is still Li2O2.

text: Understanding charge carrier transport in Li2O2, the storage material in the
non-aqueous Li-O2 battery, is key to the development of this high-energy battery.
Here, we studied ionic transport properties and Li self-diffusion in nanocrystalline
Li2O2 by conductivity and temperature variable 7Li NMR spectroscopy. Nanostructured
Li2O2, characterized by a mean crystallite size of less than 50 nm as estimated
from X-ray diffraction peak broadening, was prepared by high-energy ball milling
of microcrystalline lithium peroxide with μm sized crystallites. At room temperature
the overall conductivity σ of the microcrystalline reference sample turned out
to be very low (3.4 × 10−13 S cm−1) which is in agreement with results from temperature-variable
7Li NMR line shape measurements. Ball-milling, however, leads to an increase of
σ by approximately two orders of magnitude (1.1 × 10−10 S cm−1); correspondingly,
the activation energy decreases from 0.89 eV to 0.82 eV. The electronic contribution
σeon, however, is in the order of 9 × 10−12 S cm−1 which makes less than 10% of
the total value. Interestingly, 7Li NMR lines of nano-Li2O2 undergo pronounced
heterogeneous motional narrowing which manifests in a two-component line shape
emerging with increasing temperatures. Most likely, the enhancement in σ can be
traced back to the generation of a spin reservoir with highly mobile Li ions;
these are expected to reside in the nearest neighbourhood of defects generated
or near the structurally disordered and defect-rich interfacial regions formed
during mechanical treatment.
