text: 'We resolve several longstanding problems concerning the stability and the
absence of multi-particle binding for N≥2 polarons. Fröhlich''s 1937 polaron model
describes non-relativistic particles interacting with a scalar quantized field
with coupling √α, and with each other by Coulomb repulsion of strength U. We prove
the following: (i) While there is a known thermodynamic instability for U<2α,
stability of matter does hold for U>2α, that is, the ground state energy per
particle has a finite limit as N→∞. (ii) There is no binding of any kind if U
exceeds a critical value that depends on α but not on N. The same results are
shown to hold for the Pekar-Tomasevich model.'

text: The change in energy of an ideal Fermi gas when a local one-body potential
is inserted into the system, or when the density is changed locally, are important
quantities in condensed matter physics. We show that they can be rigorously bounded
from below by a universal constant times the value given by the semiclassical
approximation.

text: This article refers to algorithms based on finite difference schemes for computing
mean and affine curvature evolutions of digital images, introduced by Alvarez
and Morel [L. Alvarez, J.M. Morel, “Formalization and computational aspects of
image analysis”, Acta Numerica, pp. 159, 1994]. We discuss consistency, stability
and convergence. Our analysis focuses on some possible choices of the parameters,
choices that generate multiple variants in the implementations. Meaningful visual
examples on how the algorithms actually work are provided.

text: "In the present paper we give a thorough analysis of two finite difference
schemes for the Mean Curvature Motion and its affine variant, the Affine Morphological
Scale Space, schemes introduced in the Image Processing framework. This analysis
brings in a series of parameters that allow us to compute an accurate discrete
evolution of curvature motions.\r\nThe choice of these parameters is based on
intrinsic geometric properties of the evolution equations for linear, radial and
elliptical functions. In the last part we present several examples, underlining
the main advantages of the algorithms (the removal of pixelization effects and
JPEG artifacts) as well as their major drawbacks (absence of contrast invariance
and grid dependence). A detailed explanatory report, the ANSI C implementations
and an on-line demo can be found at http://www.ipol.im/."

text: Iron is a ubiquitous impurity in metamict (radiation-damaged and partially
amorphized) materials such as titanite (CaSiTiO5). Using 57Fe Mössbauer spectroscopy
we find that iron in metamict titanite is partitioned between amorphous and crystalline
regions based on valence. Trivalent iron exists in the crystalline titanite matrix
whereas divalent iron exists almost exclusively in radiation-amorphized regions.
We find that the relative abundances of the oxidation states correlate with the
volume fraction of amorphous and crystalline regions. Our data also show that
oxidation of iron proceeds along with the recrystallization of the amorphized
regions. Recrystallization is confirmed to occur over the range 700 °C < T < 925 °C,
and no further structural changes are observed at higher temperatures. It is surprising
that our Mössbauer measurements show divalent iron to be surrounded by titanite
with a high degree of short-range structural order in the amorphized regions.
This observation is fundamentally different from other metamict materials such
as zircon (ZrSiO4), where amorphized regions show no short-range order.

text: Pb, Te, Ag and Se, when reacted in a 1:1:x:1 (x = 1.9, 2.0, 2.01) molar ratio,
form a two phase composite which consists of a phase which crystallizes in the
fcc cubic PbSe structure and a phase that crystallizes in the Ag2Te structure.
In this article, we demonstrate that by varying the Ag concentration, we can manipulate
which variant of the Ag2Te structure stabilizes at room temperature (monoclinic
α-Ag2Te or cubic β-Ag1.9Te) and can consequently manipulate the electrical and
thermal transport behavior of the composite and hence the thermoelectric performance.
Additionally, we show that Cu-doping results in an overall improvement in thermoelectric
performance. Our results suggest that formation of composites is a viable path
for achieving a phonon-glass-electron-crystal (PGEC) alloy.

text: 'Li-ion batteries have transformed portable electronics and will play a key
role in the electrification of transport. However, the highest energy storage
possible for Li-ion batteries is insufficient for the long-term needs of society,
for example, extended-range electric vehicles. To go beyond the horizon of Li-ion
batteries is a formidable challenge; there are few options. Here we consider two:
Li–air (O2) and Li–S. The energy that can be stored in Li–air (based on aqueous
or non-aqueous electrolytes) and Li–S cells is compared with Li-ion; the operation
of the cells is discussed, as are the significant hurdles that will have to be
overcome if such batteries are to succeed. Fundamental scientific advances in
understanding the reactions occurring in the cells as well as new materials are
key to overcoming these obstacles. The potential benefits of Li–air and Li–S justify
the continued research effort that will be needed.'

of the non‐aqueous Li–O2 battery. Although ether‐based electrolytes do from Li2O2

text: The nonaqueous rechargeable lithium–O2 battery containing an alkyl carbonate
electrolyte discharges by formation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li,
CO2, and H2O at the cathode, due to electrolyte decomposition. Charging involves
oxidation of C3H6(OCO2Li)2, Li2CO3, HCO2Li, CH3CO2Li accompanied by CO2 and H2O
evolution. Mechanisms are proposed for the reactions on discharge and charge.
The different pathways for discharge and charge are consistent with the widely
observed voltage gap in Li–O2 cells. Oxidation of C3H6(OCO2Li)2 involves terminal
carbonate groups leaving behind the OC3H6O moiety that reacts to form a thick
gel on the Li anode. Li2CO3, HCO2Li, CH3CO2Li, and C3H6(OCO2Li)2 accumulate in
the cathode on cycling correlating with capacity fading and cell failure. The
latter is compounded by continuous consumption of the electrolyte on each discharge.

text: Lithium-metal oxides with a high formal Li2O content, such as Li5FeO4 (5Li2O•Fe2O3)
and a Li2MnO3•LiFeO2 composite ({Li2O•MnO2}•{Li2O•Fe2O3}) have been explored as
electrocatalysts for primary and rechargeable Li-O2 cells. Activation occurs predominantly
by Li2O removal, either electrochemically or chemically by acid-treatment. Superior
electrochemical behavior is obtained if activation occurs by acid-treatment; Li2MnO3•LiFeO2
catalysts provide 2516 mAh/g (carbon) corresponding to 931 mAh/g (electrocatalyst
+ carbon) during the initial discharge. The reaction is reasonably reversible
during the early cycles. The approach has implications for designing electrocatalysts
that participate through electrochemical Li2O extraction/reformation reactions,
offering exceptionally high capacities.

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 synchronization into
an algorithm that tolerates asynchronous executions. We introduce a transformation
technique from synchronous algorithms to indulgent algorithms [1], 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 a large class of colorless 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: 'We study the complexity of renaming, a fundamental problem in distributed
computing in which a set of processes need to pick distinct names from a given
namespace. We prove an individual lower bound of Ω(k) process steps for deterministic
renaming into any namespace of size sub-exponential in k, where k is the number
of participants. This bound is tight: it draws an exponential separation between
deterministic and randomized solutions, and implies new tight bounds for deterministic
fetch-and-increment registers, queues and stacks. The proof of the bound is interesting
in its own right, for it relies on the first reduction from renaming to another
fundamental problem in distributed computing: mutual exclusion. We complement
our individual bound with a global lower bound of Ω(k log (k/c)) on the total
step complexity of renaming into a namespace of size ck, for any c ≥ 1. This applies
to randomized algorithms against a strong adversary, and helps derive new global
lower bounds for randomized approximate counter and fetch-and-increment implementations,
all tight within logarithmic factors.'

text: We give two new randomized algorithms for strong renaming, both of which work
against an adaptive adversary in asynchronous shared memory. The first uses repeated
sampling over a sequence of arrays of decreasing size to assign unique names to
each of n processes with step complexity O(log3 n). The second transforms any
sorting network into a strong adaptive renaming protocol, with an expected cost
equal to the depth of the sorting network. Using an AKS sorting network, this
gives a strong adaptive renaming algorithm with step complexity O(log k), where
k is the contention in the current execution. We show this to be optimal based
on a classic lower bound of Jayanti. We also show that any such strong renaming
protocol can be used to build a monotone-consistent counter with logarithmic step
complexity (at the cost of adding a max register) or a linearizable fetch-and-increment
register (at the cost of increasing the step complexity by a logarithmic factor).

text: During assembly of the Drosophila olfactory circuit, projection neuron (PN)
dendrites prepattern the developing antennal lobe before the arrival of axons
from their presynaptic partners, the adult olfactory receptor neurons (ORNs).
We previously found that levels of transmembrane Semaphorin-1a, which acts as
a receptor, instruct PN dendrite targeting along the dorsolateral-ventromedial
axis. Here we show that two secreted semaphorins, Sema-2a and Sema-2b, provide
spatial cues for PN dendrite targeting. Sema-2a and Sema-2b proteins are distributed
in gradients opposing the Sema-1a protein gradient, and Sema-1a binds to Sema-2a-expressing
cells. In Sema-2a and Sema-2b double mutants, PN dendrites that normally target
dorsolaterally in the antennal lobe mistarget ventromedially, phenocopying cell-autonomous
Sema-1a removal from these PNs. Cell ablation, cell-specific knockdown, and rescue
experiments indicate that secreted semaphorins from degenerating larval ORN axons
direct dendrite targeting. Thus, a degenerating brain structure instructs the
wiring of a developing circuit through the repulsive action of secreted semaphorins.
