text: Composite materials offer numerous advantages in a wide range of applications,
including thermoelectrics. Here, semiconductor–metal composites are produced by
just blending nanoparticles of a sulfide semiconductor obtained in aqueous solution
and at room temperature with a metallic Cu powder. The obtained blend is annealed
in a reducing atmosphere and afterward consolidated into dense polycrystalline
pellets through spark plasma sintering (SPS). We observe that, during the annealing
process, the presence of metallic copper activates a partial reduction of the
PbS, resulting in the formation of PbS–Pb–CuxS composites. The presence of metallic
lead during the SPS process habilitates the liquid-phase sintering of the composite.
Besides, by comparing the transport properties of PbS, the PbS–Pb–CuxS composites,
and PbS–CuxS composites obtained by blending PbS and CuxS nanoparticles, we demonstrate
that the presence of metallic lead decisively contributes to a strong increase
of the charge carrier concentration through spillover of charge carriers enabled
by the low work function of lead. The increase in charge carrier concentration
translates into much higher electrical conductivities and moderately lower Seebeck
coefficients. These properties translate into power factors up to 2.1 mW m–1 K–2
at ambient temperature, well above those of PbS and PbS + CuxS. Additionally,
the presence of multiple phases in the final composite results in a notable decrease
in the lattice thermal conductivity. Overall, the introduction of metallic copper
in the initial blend results in a significant improvement of the thermoelectric
performance of PbS, reaching a dimensionless thermoelectric figure of merit ZT
= 1.1 at 750 K, which represents about a 400% increase over bare PbS. Besides,
an average ZTave = 0.72 in the temperature range 320–773 K is demonstrated.

text: Cu2–xS has become one of the most promising thermoelectric materials for application
in the middle-high temperature range. Its advantages include the abundance, low
cost, and safety of its elements and a high performance at relatively elevated
temperatures. However, stability issues limit its operation current and temperature,
thus calling for the optimization of the material performance in the middle temperature
range. Here, we present a synthetic protocol for large scale production of covellite
CuS nanoparticles at ambient temperature and atmosphere, and using water as a
solvent. The crystal phase and stoichiometry of the particles are afterward tuned
through an annealing process at a moderate temperature under inert or reducing
atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral
crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal
Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed
in argon to transform to the cubic phase at ca. 400 K, while the material annealed
in the presence of hydrogen undergoes two phase transitions, first to hexagonal
and then to the cubic structure. The annealing atmosphere, temperature, and time
allow adjustment of the density of copper vacancies and thus tuning of the charge
carrier concentration and material transport properties. In this direction, the
material annealed under Ar is characterized by higher electrical conductivities
but lower Seebeck coefficients than the material annealed in the presence of hydrogen.
By optimizing the charge carrier concentration through the annealing time, Cu2–xS
with record figures of merit in the middle temperature range, up to 1.41 at 710
K, is obtained. We finally demonstrate that this strategy, based on a low-cost
and scalable solution synthesis process, is also suitable for the production of
high performance Cu2–xS layers using high throughput and cost-effective printing
technologies.

text: We investigate the effect of coupling between translational and internal degrees
of freedom of composite quantum particles on their localization in a random potential.
We show that entanglement between the two degrees of freedom weakens localization
due to the upper bound imposed on the inverse participation ratio by purity of
a quantum state. We perform numerical calculations for a two-particle system bound
by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered
lattice. We illustrate that the coupling has a dramatic effect on localization
properties, even with a small number of internal states participating in quantum
dynamics.

text: Phenomenological relations such as Ohm’s or Fourier’s law have a venerable
history in physics but are still scarce in biology. This situation restrains predictive
theory. Here, we build on bacterial “growth laws,” which capture physiological
feedback between translation and cell growth, to construct a minimal biophysical
model for the combined action of ribosome-targeting antibiotics. Our model predicts
drug interactions like antagonism or synergy solely from responses to individual
drugs. We provide analytical results for limiting cases, which agree well with
numerical results. We systematically refine the model by including direct physical
interactions of different antibiotics on the ribosome. In a limiting case, our
model provides a mechanistic underpinning for recent predictions of higher-order
interactions that were derived using entropy maximization. We further refine the
model to include the effects of antibiotics that mimic starvation and the presence
of resistance genes. We describe the impact of a starvation-mimicking antibiotic
on drug interactions analytically and verify it experimentally. Our extended model
suggests a change in the type of drug interaction that depends on the strength
of resistance, which challenges established rescaling paradigms. We experimentally
show that the presence of unregulated resistance genes can lead to altered drug
interaction, which agrees with the prediction of the model. While minimal, the
model is readily adaptable and opens the door to predicting interactions of second
and higher-order in a broad range of biological systems.

text: Acquired mutations are sufficiently frequent such that the genome of a single
cell offers a record of its history of cell divisions. Among more common somatic
genomic alterations are loss of heterozygosity (LOH). Large LOH events are potentially
detectable in single cell RNA sequencing (scRNA-seq) datasets as tracts of monoallelic
expression for constitutionally heterozygous single nucleotide variants (SNVs)
located among contiguous genes. We identified runs of monoallelic expression,
consistent with LOH, uniquely distributed throughout the genome in single cell
brain cortex transcriptomes of F1 hybrids involving different inbred mouse strains.
We then phylogenetically reconstructed single cell lineages and simultaneously
identified cell types by corresponding gene expression patterns. Our results are
consistent with progenitor cells giving rise to multiple cortical cell types through
stereotyped expansion and distinct waves of neurogenesis. Compared to engineered
recording systems, LOH events accumulate throughout the genome and across the
lifetime of an organism, affording tremendous capacity for encoding lineage information
and increasing resolution for later cell divisions. This approach can conceivably
be computationally incorporated into scRNA-seq analysis and may be useful for
organisms where genetic engineering is prohibitive, such as humans.

text: A precise quantitative description of the ultrastructural characteristics
underlying biological mechanisms is often key to their understanding. This is
particularly true for dynamic extra- and intracellular filamentous assemblies,
playing a role in cell motility, cell integrity, cytokinesis, tissue formation
and maintenance. For example, genetic manipulation or modulation of actin regulatory
proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural
architecture of actin filament-rich cell peripheral structures, such as lamellipodia
or filopodia. However, the observed ultrastructural effects often remain subtle
and require sufficiently large datasets for appropriate quantitative analysis.
The acquisition of such large datasets has been enabled by recent advances in
high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates
the development of complementary approaches to maximize the extraction of relevant
biological information. We have developed a computational toolbox for the semi-automatic
quantification of segmented and vectorized filamentous networks from pre-processed
cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple
experimental conditions. GUI-based components simplify the processing of data
and allow users to obtain a large number of ultrastructural parameters describing
filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing
cryo-ET data of untreated and chemically perturbed branched actin filament networks
and that of parallel actin filament arrays. In principle, the computational toolbox
presented here is applicable for data analysis comprising any type of filaments
in regular (i.e. parallel) or random arrangement. We show that it can ease the
identification of key differences between experimental groups and facilitate the
in-depth analysis of ultrastructural data in a time-efficient manner.

text: We report the complete analysis of a deterministic model of deleterious mutations
and negative selection against them at two haploid loci without recombination.
As long as mutation is a weaker force than selection, mutant alleles remain rare
at the only stable equilibrium, and otherwise, a variety of dynamics are possible.
If the mutation-free genotype is absent, generally the only stable equilibrium
is the one that corresponds to fixation of the mutant allele at the locus where
it is less deleterious. This result suggests that fixation of a deleterious allele
that follows a click of the Muller’s ratchet is governed by natural selection,
instead of random drift.

text: Solution synthesis of particles emerged as an alternative to prepare thermoelectric
materials with less demanding processing conditions than conventional solid-state
synthetic methods. However, solution synthesis generally involves the presence
of additional molecules or ions belonging to the precursors or added to enable
solubility and/or regulate nucleation and growth. These molecules or ions can
end up in the particles as surface adsorbates and interfere in the material properties.
This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically
adsorbed in SnSe particles synthesized in water and play a crucial role not only
in directing the material nano/microstructure but also in determining the transport
properties of the consolidated material. In dense pellets prepared by sintering
SnSe particles, Na remains within the crystal lattice as dopant, in dislocations,
precipitates, and forming grain boundary complexions. These results highlight
the importance of considering all the possible unintentional impurities to establish
proper structure-property relationships and control material properties in solution-processed
thermoelectric materials.

text: Tissue morphogenesis is driven by mechanical forces triggering cell movements
and shape changes. Quantitatively measuring tension within tissues is of great
importance for understanding the role of mechanical signals acting on the cell
and tissue level during morphogenesis. Here we introduce laser ablation as a useful
tool to probe tissue tension within the granulosa layer, an epithelial monolayer
of somatic cells that surround the zebrafish female gamete during folliculogenesis.
We describe in detail how to isolate follicles, mount samples, perform laser surgery,
and analyze the data.

text: The security of cryptographic primitives and protocols against adversaries
that are allowed to make adaptive choices (e.g., which parties to corrupt or which
queries to make) is notoriously difficult to establish. A broad theoretical framework
was introduced by Jafargholi et al. [Crypto’17] for this purpose. In this paper
we initiate the study of lower bounds on loss in adaptive security for certain
cryptographic protocols considered in the framework. We prove lower bounds that
almost match the upper bounds (proven using the framework) for proxy re-encryption,
prefix-constrained PRFs and generalized selective decryption, a security game
that captures the security of certain group messaging and broadcast encryption
schemes. Those primitives have in common that their security game involves an
underlying graph that can be adaptively built by the adversary. Some of our lower
bounds only apply to a restricted class of black-box reductions which we term
“oblivious” (the existing upper bounds are of this restricted type), some apply
to the broader but still restricted class of non-rewinding reductions, while our
lower bound for proxy re-encryption applies to all black-box reductions. The fact
that some of our lower bounds seem to crucially rely on obliviousness or at least
a non-rewinding reduction hints to the exciting possibility that the existing
upper bounds can be improved by using more sophisticated reductions. Our main
conceptual contribution is a two-player multi-stage game called the Builder-Pebbler
Game. We can translate bounds on the winning probabilities for various instantiations
of this game into cryptographic lower bounds for the above-mentioned primitives
using oracle separation techniques.

text: We show that Yao’s garbling scheme is adaptively indistinguishable for the
class of Boolean circuits of size S and treewidth w with only a SO(w) loss
in security. For instance, circuits with constant treewidth are as a result adaptively
indistinguishable with only a polynomial loss. This (partially) complements a
negative result of Applebaum et al. (Crypto 2013), which showed (assuming one-way
functions) that Yao’s garbling scheme cannot be adaptively simulatable. As main
technical contributions, we introduce a new pebble game that abstracts out our
security reduction and then present a pebbling strategy for this game where the
number of pebbles used is roughly O(δwlog(S)) , δ being the fan-out of the
circuit. The design of the strategy relies on separators, a graph-theoretic notion
with connections to circuit complexity. with only a SO(w) loss in security.

text: "The security of cryptographic primitives and protocols against adversaries
that are allowed to make adaptive choices (e.g., which parties to corrupt or which
queries to make) is notoriously difficult to establish. A broad theoretical\r\nframework
was introduced by Jafargholi et al. [Crypto’17] for this purpose. In this paper
we initiate the study of lower bounds on loss in adaptive security for certain
cryptographic protocols considered in the framework. We prove lower\r\nbounds
that almost match the upper bounds (proven using the framework) for proxy re-encryption,
prefix-constrained PRFs and generalized selective decryption, a security game
that captures the security of certain group messaging and\r\nbroadcast encryption
schemes. Those primitives have in common that their security game involves an
underlying graph that can be adaptively built by the adversary. Some of our lower
bounds only apply to a restricted class of black-box reductions which we term
“oblivious” (the existing upper bounds are of this restricted type), some apply
to the broader but still restricted class of non-rewinding reductions, while our
lower bound for proxy re-encryption applies to all black-box reductions. The fact
that some of our lower bounds seem to crucially rely on obliviousness or at least
a non-rewinding reduction hints to the exciting possibility that the existing
upper bounds can be improved by using more sophisticated reductions. Our main
conceptual contribution is a two-player multi-stage game called the Builder-Pebbler
Game. We can translate bounds on the winning probabilities for various instantiations
of this game into cryptographic lower bounds for the above-mentioned primitives
using oracle separation techniques.\r\n"

text: We show that Yao’s garbling scheme is adaptively indistinguishable for the
class of Boolean circuits of size S and treewidth w with only a S^O(w) loss in
security. For instance, circuits with constant treewidth are as a result adaptively
indistinguishable with only a polynomial loss. This (partially) complements a
negative result of Applebaum et al. (Crypto 2013), which showed (assuming one-way
functions) that Yao’s garbling scheme cannot be adaptively simulatable. As main
technical contributions, we introduce a new pebble game that abstracts out our
security reduction and then present a pebbling strategy for this game where the
number of pebbles used is roughly O(d w log(S)), d being the fan-out of the circuit.
The design of the strategy relies on separators, a graph-theoretic notion with
connections to circuit complexity.

landscape of adaptive security of Yao’s garbling. '

text: 'In two-player games on graphs, the players move a token through a graph to
produce an infinite path, which determines the winner of the game. Such games
are central in formal methods since they model the interaction between a non-terminating
system and its environment. In bidding games the players bid for the right to
move the token: in each round, the players simultaneously submit bids, and the
higher bidder moves the token and pays the other player. Bidding games are known
to have a clean and elegant mathematical structure that relies on the ability
of the players to submit arbitrarily small bids. Many applications, however, require
a fixed granularity for the bids, which can represent, for example, the monetary
value expressed in cents. We study, for the first time, the combination of discrete-bidding
and infinite-duration games. Our most important result proves that these games
form a large determined subclass of concurrent games, where determinacy is the
strong property that there always exists exactly one player who can guarantee
winning the game. In particular, we show that, in contrast to non-discrete bidding
games, the mechanism with which tied bids are resolved plays an important role
in discrete-bidding games. We study several natural tie-breaking mechanisms and
show that, while some do not admit determinacy, most natural mechanisms imply
determinacy for every pair of initial budgets.'

text: We study the temporal dissipation of variance and relative entropy for ergodic
Markov Chains in continuous time, and compute explicitly the corresponding dissipation
rates. These are identified, as is well known, in the case of the variance in
terms of an appropriate Hilbertian norm; and in the case of the relative entropy,
in terms of a Dirichlet form which morphs into a version of the familiar Fisher
information under conditions of detailed balance. Here we obtain trajectorial
versions of these results, valid along almost every path of the random motion
and most transparent in the backwards direction of time. Martingale arguments
and time reversal play crucial roles, as in the recent work of Karatzas, Schachermayer
and Tschiderer for conservative diffusions. Extensions are developed to general
“convex divergences” and to countable state-spaces. The steepest descent and gradient
flow properties for the variance, the relative entropy, and appropriate generalizations,
are studied along with their respective geometries under conditions of detailed
balance, leading to a very direct proof for the HWI inequality of Otto and Villani
in the present context.

text: Two common representations of close packings of identical spheres consisting
of hexagonal layers, called Barlow stackings, appear abundantly in minerals and
metals. These motifs, however, occupy an identical portion of space and bear identical
first-order topological signatures as measured by persistent homology. Here we
present a novel method based on k-fold covers that unambiguously distinguishes
between these patterns. Moreover, our approach provides topological evidence that
the FCC motif is the more stable of the two in the context of evolving experimental
sphere packings during the transition from disordered to an ordered state. We
conclude that our approach can be generalised to distinguish between various Barlow
stackings manifested in minerals and metals.

text: This thesis is the result of the research carried out by the author during
his PhD at IST Austria between 2017 and 2021. It mainly focuses on the Fröhlich
polaron model, specifically to its regime of strong coupling. This model, which
is rigorously introduced and discussed in the introduction, has been of great
interest in condensed matter physics and field theory for more than eighty years.
It is used to describe an electron interacting with the atoms of a solid material
(the strength of this interaction is modeled by the presence of a coupling constant
α in the Hamiltonian of the system). The particular regime examined here, which
is mathematically described by considering the limit α →∞, displays many interesting
features related to the emergence of classical behavior, which allows for a simplified
effective description of the system under analysis. The properties, the range
of validity and a quantitative analysis of the precision of such classical approximations
are the main object of the present work. We specify our investigation to the study
of the ground state energy of the system, its dynamics and its effective mass.
For each of these problems, we provide in the introduction an overview of the
previously known results and a detailed account of the original contributions
by the author.

text: Consider a random set of points on the unit sphere in ℝd, which can be either
uniformly sampled or a Poisson point process. Its convex hull is a random inscribed
polytope, whose boundary approximates the sphere. We focus on the case d = 3,
for which there are elementary proofs and fascinating formulas for metric properties.
In particular, we study the fraction of acute facets, the expected intrinsic volumes,
the total edge length, and the distance to a fixed point. Finally we generalize
the results to the ellipsoid with homeoid density.

text: 'Volumetric light transport is a pervasive physical phenomenon, and therefore
its accurate simulation is important for a broad array of disciplines. While suitable
mathematical models for computing the transport are now available, obtaining the
necessary material parameters needed to drive such simulations is a challenging
task: direct measurements of these parameters from material samples are seldom
possible. Building on the inverse scattering paradigm, we present a novel measurement
approach which indirectly infers the transport parameters from extrinsic observations
of multiple-scattered radiance. The novelty of the proposed approach lies in replacing
structured illumination with a structured reflector bonded to the sample, and
a robust fitting procedure that largely compensates for potential systematic errors
in the calibration of the setup. We show the feasibility of our approach by validating
simulations of complex 3D compositions of the measured materials against physical
prints, using photo-polymer resins. As presented in this paper, our technique
yields colorspace data suitable for accurate appearance reproduction in the area
of 3D printing. Beyond that, and without fundamental changes to the basic measurement
methodology, it could equally well be used to obtain spectral measurements that
are useful for other application areas.'
