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: 'Nanocomposites are highly promising materials to enhance the efficiency of
current thermoelectric devices. A straightforward and at the same time highly
versatile and controllable approach to produce nanocomposites is the assembly
of solution-processed nanocrystal building blocks. The convenience of this bottom-up
approach to produce nanocomposites with homogeneous phase distributions and adjustable
composition is demonstrated here by blending Ag2Te and PbTe colloidal nanocrystals
to form Ag2Te–PbTe bulk nanocomposites. The thermoelectric properties of these
nanocomposites are analyzed in the temperature range from 300 to 700 K. The evolution
of their electrical conductivity and Seebeck coefficient is discussed in terms
of the blend composition and the characteristics of the constituent materials. '

text: Arrays of vertically aligned ZnO : Cl/TiO2 and ZnO : Cl/ZnxTiOy/TiO2 core–shell
nanowires (NWs) were prepared by means of the combination of two solution-growth
processes. First, single-crystal ZnO NWs with controlled n-type doping were grown
on conducting substrates by a low-cost, high-yield and seed-free electrochemical
route. These NWs were covered by a titanium oxide shell of tunable thickness mediating
successive adsorption-hydrolysis-condensation steps. Using this atomic-layer growth
procedure, titania shells with controlled thickness and the anatase TiO2 phase
were obtained after sintering at 450 °C. Higher sintering temperatures resulted
in the formation of ZnO : Cl/ZnxTiOy/TiO2 core–shell NWs by the interdiffusion
of Zn and Ti ions at the ZnO–TiO2 interface. The performance of ZnO : Cl/TiO2
and ZnO : Cl/ZnxTiOy/TiO2 core–shell NWs towards photoelectrochemical (PEC) water
splitting was investigated as a function of the titania shell thickness. Furthermore,
the performance of such core–shell NWs as photoelectrodes in dye-sensitized solar
cells was also characterized. The TiO2 presence at the ZnO : Cl surface promoted
a two-fold increase on the produced photocurrent densities, probing their potential
for PEC and optoelectronic applications. Electrochemical impedance spectroscopy
was used to corroborate the lower resistance for charge transfer between the NWs
and the electrolyte in the presence of the TiO2 shell.

text: 'A synthetic route for producing Cu 2ZnGeSe 4 nanocrystals with narrow size
distributions and controlled composition is presented. These nanocrystals were
used to produce densely packed nanomaterials by hot-pressing. From the characterization
of the thermoelectric properties of these nanomaterials, Cu 2ZnGeSe 4 is demonstrated
to show excellent thermoelectric properties. A very preliminary adjustment of
the nanocrystal composition has already resulted in a figure of merit of up to
0.55 at 450°C. '

text: The potential to control the composition and crystal phase at the nanometer
scale enable the production of nanocrystalline materials with enhanced functionalities
and new applications. In the present work, we detail a novel colloidal synthesis
route to prepare nanoparticles of the ternary semiconductor Cu2GeSe3 (CGSe) with
nanometer-scale control over their crystal phases. We also demonstrate the structural
effect on the thermoelectric properties of bottom-up-prepared CGSe nanomaterials.
By careful adjustment of the nucleation and growth temperatures, pure orthorhombic
CGSe nanoparticles with cationic order or polytypic CGSe nanoparticles with disordered
cation positions can be produced. In this second type of nanoparticle, a high
density of twins can be created to periodically change the atomic plane stacking,
forming a hexagonal wurtzite CGSe phase. The high yield of the synthetic routes
reported here allows the production of single-phase and multiphase CGSe nanoparticles
in the gram scale, which permits characterization of the thermoelectric properties
of these materials. Reduced thermal conductivities and a related 2.5-fold increase
of the thermoelectric figure of merit for multiphase nanomaterials compared to
pure-phase CGSe are systematically obtained. These results are discussed in terms
of the density and efficiency of phonon scattering centers in both types of materials.

text: Hierarchical Timing Language (HTL) is a coordination language for distributed,
hard real-time applications. HTL is a hierarchical extension of Giotto and, like
its predecessor, based on the logical execution time (LET) paradigm of real-time
programming. Giotto is compiled into code for a virtual machine, called the EmbeddedMachine
(or E machine). If HTL is targeted to the E machine, then the hierarchicalprogram
structure needs to be flattened; the flattening makes separatecompilation difficult,
and may result in E machinecode of exponential size. In this paper, we propose
a generalization of the E machine, which supports a hierarchicalprogram structure
at runtime through real-time trigger mechanisms that are arranged in a tree. We
present the generalized E machine, and a modular compiler for HTL that generates
code of linear size. The compiler may generate code for any part of a given HTL
program separately in any order.

text: We summarize classical and recent results about two-player games played on
graphs with ω-regular objectives. These games have applications in the verification
and synthesis of reactive systems. Important distinctions are whether a graph
game is turn-based or concurrent; deterministic or stochastic; zero-sum or not.
We cluster known results and open problems according to these classifications.

text: In this Letter we present detailed study of the density of states near defects
in Bi 2Se 3. In particular, we present data on the commonly found triangular defects
in this system. While we do not find any measurable quasiparticle scattering interference
effects, we do find localized resonances, which can be well fitted by theory once
the potential is taken to be extended to properly account for the observed defects.
The data together with the fits confirm that while the local density of states
around the Dirac point of the electronic spectrum at the surface is significantly
disrupted near the impurity by the creation of low-energy resonance state, the
Dirac point is not locally destroyed. We discuss our results in terms of the expected
protected surface state of topological insulators. © 2012 American Physical Society.

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: 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: 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: 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. '
