text: "We consider the problem of computing the maximal probability of satisfying
an \r\n-regular specification for stochastic, continuous-state, nonlinear systems
evolving in discrete time. The problem reduces, after automata-theoretic constructions,
to finding the maximal probability of satisfying a parity condition on a (possibly
hybrid) state space. While characterizing the exact satisfaction probability is
open, we show that a lower bound on this probability can be obtained by (I) computing
an under-approximation of the qualitative winning region, i.e., states from which
the parity condition can be enforced almost surely, and (II) computing the maximal
probability of reaching this qualitative winning region.\r\nThe heart of our approach
is a technique to symbolically compute the under-approximation of the qualitative
winning region in step (I) via a finite-state abstraction of the original system
as a \r\n-player parity game. Our abstraction procedure uses only the support
of the probabilistic evolution; it does not use precise numerical transition probabilities.
We prove that the winning set in the abstract -player game induces an under-approximation
of the qualitative winning region in the original synthesis problem, along with
a policy to solve it. By combining these contributions with (a) a symbolic fixpoint
algorithm to solve \r\n-player games and (b) existing techniques for reachability
policy synthesis in stochastic nonlinear systems, we get an abstraction-based
algorithm for finding a lower bound on the maximal satisfaction probability.\r\nWe
have implemented the abstraction-based algorithm in Mascot-SDS, where we combined
the outlined abstraction step with our tool Genie (Majumdar et al., 2023) that
solves \r\n-player parity games (through a reduction to Rabin games) more efficiently
than existing algorithms. We evaluated our implementation on the nonlinear model
of a perturbed bistable switch from the literature. We show empirically that the
lower bound on the winning region computed by our approach is precise, by comparing
against an over-approximation of the qualitative winning region. Moreover, our
implementation outperforms a recently proposed tool for solving this problem by
a large margin."
acknowledgement: "We thank Daniel Hausmann and Nir Piterman for their valuable comments
on an earlier version of the manuscript of our other paper [22] where we present,
among other things, the parity fixpoint for 2 1/2-player games (for a slightly more
general class of games) with a different and indirect proof of correctness. Based
on their comments we observed that, unlike the other fixpoints that we present in
[22], the parity fixpoint does not follow the exact same structure as its counterpart
for 2-player games, which we also use int his paper.\r\nWe also thank Thejaswini
Raghavan for observing that our symbolic parity fixpoint algorithm can be solved
in quasi-polynomial time using recent improved algorithms for solving \r\n-calculus
expressions. This significantly improved the complexity bounds of our algorithm
in this paper.\r\nThe work of R. Majumdar and A.-K. Schmuck are partially supported

text: Low‐cost, safe, and environmental‐friendly rechargeable aqueous zinc‐ion batteries
(ZIBs) are promising as next‐generation energy storage devices for wearable electronics
among other applications. However, sluggish ionic transport kinetics and the unstable
electrode structure during ionic insertion/extraction hampers their deployment.
Herein, we propose a new cathode material based on a layered metal chalcogenide
(LMC), bismuth telluride (Bi2Te3), coated
with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi2Te3@PPy
composite presents strong ionic absorption affinity, high oxidation resistance,
and high structural stability. The ZIBs based on Bi2Te3@PPy
cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles.
They also present outstanding stability even under bending. In addition, we analyze
here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron
spectroscopy, and computational tools and demonstrate that, in the aqueous system,
Zn2+ is not inserted into the cathode as previously assumed.
In contrast, proton charge storage dominates the process. Overall, this work not
only shows the great potential of LMCs as ZIBs cathode materials and the advantages
of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable
ZIBs based on LMCs.

text: "Auxin belongs among major phytohormones and governs multiple aspects of plant
growth and development. The establishment of auxin concentration gradients, determines,
among other processes, plant organ positioning and growth responses to environmental
stimuli.\r\nHerein we report the synthesis of new NBD- or DNS-labelled IAA derivatives
and the elucidation of their biological activity, fluorescence properties and
subcellular accumulation patterns in planta. These novel compounds did not show
auxin-like activity, but instead antagonized physiological auxin effects. The
DNS-labelled derivatives FL5 and FL6 showed strong anti-auxin activity in roots
and hypocotyls, which also occurred at the level of gene transcription as confirmed
by quantitative PCR analysis. The auxin antagonism of our derivatives was further
demonstrated in vitro using an SPR-based binding assay. The NBD-labelled compound
FL4 with the best fluorescence properties proved to be unsuitable to study auxin
accumulation patterns in planta. On the other hand, the strongest anti-auxin activity
possessing compounds FL5 and FL6 could be useful to study binding mechanisms to
auxin receptors and for manipulations of auxin-regulated processes."

text: 'We investigate the potential of Multi-Objective, Deep Reinforcement Learning
for stock and cryptocurrency single-asset trading: in particular, we consider
a Multi-Objective algorithm which generalizes the reward functions and discount
factor (i.e., these components are not specified a priori, but incorporated in
the learning process). Firstly, using several important assets (BTCUSD, ETHUSDT,
XRPUSDT, AAPL, SPY, NIFTY50), we verify the reward generalization property of
the proposed Multi-Objective algorithm, and provide preliminary statistical evidence
showing increased predictive stability over the corresponding Single-Objective
strategy. Secondly, we show that the Multi-Objective algorithm has a clear edge
over the corresponding Single-Objective strategy when the reward mechanism is
sparse (i.e., when non-null feedback is infrequent over time). Finally, we discuss
the generalization properties with respect to the discount factor. The entirety
of our code is provided in open-source format.'

text: Inversions are thought to play a key role in adaptation and speciation, suppressing
recombination between diverging populations. Genes influencing adaptive traits
cluster in inversions, and changes in inversion frequencies are associated with
environmental differences. However, in many organisms, it is unclear if inversions
are geographically and taxonomically widespread. The intertidal snail, Littorina
saxatilis, is one such example. Strong associations between putative polymorphic
inversions and phenotypic differences have been demonstrated between two ecotypes
of L. saxatilis in Sweden and inferred elsewhere, but no direct evidence for inversion
polymorphism currently exists across the species range. Using whole genome data
from 107 snails, most inversion polymorphisms were found to be widespread across
the species range. The frequencies of some inversion arrangements were significantly
different among ecotypes, suggesting a parallel adaptive role. Many inversions
were also polymorphic in the sister species, L. arcana, hinting at an ancient
origin.

text: Entire chromosomes are typically only transmitted vertically from one generation
to the next. The horizontal transfer of such chromosomes has long been considered
improbable, yet gained recent support in several pathogenic fungi where it may
affect the fitness or host specificity. To date, it is unknown how these transfers
occur, how common they are and whether they can occur between different species.
In this study, we show multiple independent instances of horizontal transfers
of the same accessory chromosome between two distinct strains of the asexual entomopathogenic
fungusMetarhizium robertsiiduring experimental co-infection
of its insect host, the Argentine ant. Notably, only the one chromosome – but
no other – was transferred from the donor to the recipient strain. The recipient
strain, now harboring the accessory chromosome, exhibited a competitive advantage
under certain host conditions. By phylogenetic analysis we further demonstrate
that the same accessory chromosome was horizontally transferred in a natural environment
betweenM. robertsiiand another congeneric insect pathogen,M.
guizhouense. Hence horizontal chromosome transfer is not limited
to the observed frequent events within species during experimental infections
but also occurs naturally across species. The transferred accessory chromosome
contains genes that might be involved in its preferential horizontal transfer,
encoding putative histones and histone-modifying enzymes, but also putative virulence
factors that may support its establishment. Our study reveals that both intra-
and interspecies horizontal transfer of entire chromosomes is more frequent than
previously assumed, likely representing a not uncommon mechanism for gene exchange.Significance
StatementThe enormous success of bacterial pathogens has
been attributed to their ability to exchange genetic material between one another.
Similarly, in eukaryotes, horizontal transfer of genetic material allowed the
spread of virulence factors across species. The horizontal transfer of whole chromosomes
could be an important pathway for such exchange of genetic material, but little
is known about the origin of transferable chromosomes and how frequently they
are exchanged. Here, we show that the transfer of accessory chromosomes - chromosomes
that are non-essential but may provide fitness benefits - is common during fungal
co-infections and is even possible between distant pathogenic species, highlighting
the importance of horizontal gene transfer via chromosome transfer also for the
evolution and function of eukaryotic pathogens.

text: 'In animals, parasitic infections impose significant fitness costs.1,2,3,4,5,6
Infected animals can alter their feeding behavior to resist infection,7,8,9,10,11,12
but parasites can manipulate animal foraging behavior to their own benefits.13,14,15,16
How nutrition influences host-parasite interactions is not well understood, as
studies have mainly focused on the host and less on the parasite.9,12,17,18,19,20,21,22,23
We used the nutritional geometry framework24 to investigate the role of amino
acids (AA) and carbohydrates (C) in a host-parasite system: the Argentine ant,
Linepithema humile, and the entomopathogenic fungus, Metarhizium brunneum. First,
using 18 diets varying in AA:C composition, we established that the fungus performed
best on the high-amino-acid diet 1:4. Second, we found that the fungus reached
this optimal diet when given various diet pairings, revealing its ability to cope
with nutritional challenges. Third, we showed that the optimal fungal diet reduced
the lifespan of healthy ants when compared with a high-carbohydrate diet but had
no effect on infected ants. Fourth, we revealed that infected ant colonies, given
a choice between the optimal fungal diet and a high-carbohydrate diet, chose the
optimal fungal diet, whereas healthy colonies avoided it. Lastly, by disentangling
fungal infection from host immune response, we demonstrated that infected ants
foraged on the optimal fungal diet in response to immune activation and not as
a result of parasite manipulation. Therefore, we revealed that infected ant colonies
chose a diet that is costly for survival in the long term but beneficial in the
short term—a form of collective self-medication.'

text: 'Portrait viewpoint and illumination editing is an important problem with
several applications in VR/AR, movies, and photography. Comprehensive knowledge
of geometry and illumination is critical for obtaining photorealistic results.
Current methods are unable to explicitly model in 3D while handling both viewpoint
and illumination editing from a single image. In this paper, we propose VoRF,
a novel approach that can take even a single portrait image as input and relight
human heads under novel illuminations that can be viewed from arbitrary viewpoints.
VoRF represents a human head as a continuous volumetric field and learns a prior
model of human heads using a coordinate-based MLP with individual latent spaces
for identity and illumination. The prior model is learned in an auto-decoder manner
over a diverse class of head shapes and appearances, allowing VoRF to generalize
to novel test identities from a single input image. Additionally, VoRF has a reflectance
MLP that uses the intermediate features of the prior model for rendering One-Light-at-A-Time
(OLAT) images under novel views. We synthesize novel illuminations by combining
these OLAT images with target environment maps. Qualitative and quantitative evaluations
demonstrate the effectiveness of VoRF for relighting and novel view synthesis,
even when applied to unseen subjects under uncontrolled illumination. This work
is an extension of Rao et al. (VoRF: Volumetric Relightable Faces 2022). We provide
extensive evaluation and ablative studies of our model and also provide an application,
where any face can be relighted using textual input.'

text: In order to demonstrate the stability of newly proposed iridium-based Ir2Cr(In,Sn)
and IrRhCr(In,Sn) heusler alloys, we present ab-initio analysis of these alloys
by examining various properties to prove their stability. The stability of these
alloys can be inferred from different cohesive and formation energies as well
as positive phonon frequencies. Their electronic structure results indicate that
they are semi-metals in nature. The magnetic moments are computed using the Slater-Pauling
formula and exhibit a high value, with the Cr atom contributing the most in all
alloys. Mulliken’s charge analysis results show that our alloys contain a range
of linkages, mainly ionic and covalent ones. The ductility and mechanical stability
of these alloys are confirmed by elastic constants viz. Poisson’s ratio, Pugh’s
ratio, and many different types of elastic moduli.

text: 'Mass spectrometry imaging (MSI) is a powerful analytical technique for the
two-dimensional (2D) localization of chemicals on surfaces. Conventional MSI experiments
require to predefine the surface of interest based on photographic or microscopic
images. Typically, these boundaries can no longer be changed or adjusted once
the experiment has been started. In terms of a more interactive approach we recently
developed a pen-like ionization interface which is directly connected to the mass
spectrometer. The device allows the user to ionize chemicals by desorption electrospray
ionization (DESI) and to freely move the interface over a surface of interest.
A mini camera, which is mounted on the tip of the pen, magnifies the desorption
area and enables a simple positioning of the pen. The combination of optical data
from the camera module and chemical data obtained by mass analysis facilitates
a novel type of imaging experiment: interactive mass spectrometry imaging (IMSI).
For this application, we present a novel approach for a robust, optical flow-based
motion detection. While the live video stream from the camera is used to track
the pen''s motion across the surface a post-acquisition algorithm correlates the
coordinates of the pen trajectory with respective mass spectra obtained from a
simultaneous mass spectrometric data acquisition. This algorithm is no longer
dependent on a single, manually applied optical marker on the sample surface,
which has to be visible on all video frames throughout the analysis. The advanced
DESI-IMSI method was successfully tested on inkjet-printed letters as well as
mouse brain tissue samples. Validation of the results was done by comparing DESI-IMSI
with standard DESI-MSI data.'

text: "The classical Steinitz theorem states that if the origin belongs to the interior
of the convex hull of a set \U0001D446⊂ℝ\U0001D451, then there are at most 2\U0001D451
points of \U0001D446 whose convex hull contains the origin in the interior. Bárány,
Katchalski,and Pach proved the following quantitative version of Steinitz’s theorem.
Let \U0001D444 be a convex polytope in ℝ\U0001D451 containing the standard Euclidean
unit ball \U0001D401\U0001D451. Then there exist at most 2\U0001D451 vertices
of \U0001D444 whose convex hull \U0001D444′ satisfies \U0001D45F\U0001D401\U0001D451⊂\U0001D444′
with \U0001D45F⩾\U0001D451−2\U0001D451. They conjectured that \U0001D45F⩾\U0001D450\U0001D451−1∕2
holds with a universal constant \U0001D450>0. We prove \U0001D45F⩾15\U0001D4512,
the first polynomial lower bound on \U0001D45F. Furthermore, we show that \U0001D45F
is not greater than 2/√\U0001D451."

text: We derive lower bounds on the maximal rates for multiple packings in high-dimensional
Euclidean spaces. For any N > 0 and L ∈ Z ≥2 , a multiple packing is a set C of
points in R n such that any point in R n lies in the intersection of at most L
- 1 balls of radius √ nN around points in C . This is a natural generalization
of the sphere packing problem. We study the multiple packing problem for both
bounded point sets whose points have norm at most √ nP for some constant P > 0,
and unbounded point sets whose points are allowed to be anywhere in R n . Given
a well-known connection with coding theory, multiple packings can be viewed as
the Euclidean analog of list-decodable codes, which are well-studied over finite
fields. We derive the best known lower bounds on the optimal multiple packing
density. This is accomplished by establishing an inequality which relates the
list-decoding error exponent for additive white Gaussian noise channels, a quantity
of average-case nature, to the list-decoding radius, a quantity of worst-case
nature. We also derive novel bounds on the list-decoding error exponent for infinite
constellations and closed-form expressions for the list-decoding error exponents
for the power-constrained AWGN channel, which may be of independent interest beyond
multiple packing.

text: "Mosaic analysis with double markers (MADM) technology enables the generation
of genetic mosaic tissue in mice and high-resolution phenotyping at the individual
cell level. Here, we present a protocol for isolating MADM-labeled cells with
high yield for downstream molecular analyses using fluorescence-activated cell
sorting (FACS). We describe steps for generating MADM-labeled mice, perfusion,
single-cell suspension, and debris removal. We then detail procedures for cell
sorting by FACS and downstream analysis. This protocol is suitable for embryonic
to adult mice.\r\nFor complete details on the use and execution of this protocol,

text: Since the commercialization of brine shrimp (genus Artemia) in the 1950s,
this lineage, and in particular the model species Artemia franciscana, has been
the subject of extensive research. However, our understanding of the genetic mechanisms
underlying various aspects of their reproductive biology, including sex determination,
are still lacking. This is partly due to the scarcity of genomic resources for
Artemia species and crustaceans in general. Here, we present a chromosome-level
genome assembly of Artemia franciscana (Kellogg 1906), from the Great Salt Lake,
USA. The genome is 1GB, and the majority of the genome (81%) is scaffolded into
21 linkage groups using a previously published high-density linkage map. We performed
coverage and FST analyses using male and female genomic and transcriptomic reads
to quantify the extent of differentiation between the Z and W chromosomes. Additionally,
we quantified the expression levels in male and female heads and gonads and found
further evidence for dosage compensation in this species.

text: "In nature, different species find their niche in a range of environments,
each with its unique characteristics. While some thrive in uniform (homogeneous)
landscapes where environmental conditions stay relatively consistent across space,
others traverse the complexities of spatially heterogeneous terrains. Comprehending
how species are distributed and how they interact within these landscapes holds
the key to gaining insights into their evolutionary dynamics while also informing
conservation and management strategies.\r\n\r\nFor species inhabiting heterogeneous
landscapes, when the rate of dispersal is low compared to spatial fluctuations
in selection pressure, localized adaptations may emerge. Such adaptation in response
to varying selection strengths plays an important role in the persistence of populations
in our rapidly changing world. Hence, species in nature are continuously in a
struggle to adapt to local environmental conditions, to ensure their continued
survival. Natural populations can often adapt in time scales short enough for
evolutionary changes to influence ecological dynamics and vice versa, thereby
creating a feedback between evolution and demography. The analysis of this feedback
and the relative contributions of gene flow, demography, drift, and natural selection
to genetic variation and differentiation has remained a recurring theme in evolutionary
biology. Nevertheless, the effective role of these forces in maintaining variation
and shaping patterns of diversity is not fully understood. Even in homogeneous
environments devoid of local adaptations, such understanding remains elusive.
Understanding this feedback is crucial, for example in determining the conditions
under which extinction risk can be mitigated in peripheral populations subject
to deleterious mutation accumulation at the edges of species’ ranges\r\nas well
as in highly fragmented populations.\r\n\r\nIn this thesis we explore both uniform
and spatially heterogeneous metapopulations, investigating and providing theoretical
insights into the dynamics of local adaptation in the latter and examining the
dynamics of load and extinction as well as the impact of joint ecological and
evolutionary (eco-evolutionary) dynamics in the former. The thesis is divided
into 5 chapters.\r\n\r\nChapter 1 provides a general introduction into the subject
matter, clarifying concepts and ideas used throughout the thesis. In chapter 2,
we explore how fast a species distributed across a heterogeneous landscape adapts
to changing conditions marked by alterations in carrying capacity, selection pressure,
and migration rate.\r\n\r\nIn chapter 3, we investigate how migration selection
and drift influences adaptation and the maintenance of variation in a metapopulation
with three habitats, an extension of previous models of adaptation in two habitats.
We further develop analytical approximations for the critical threshold required
for polymorphism to persist.\r\n\r\nThe focus of chapter 4 of the thesis is on
understanding the interplay between ecology and evolution as coupled processes.
We investigate how eco-evolutionary feedback between migration, selection, drift,
and demography influences eco-evolutionary outcomes in marginal populations subject
to deleterious mutation accumulation. Using simulations as well as theoretical
approximations of the coupled dynamics of population size and allele frequency,
we analyze how gene flow from a large mainland source influences genetic load
and population size on an island (i.e., in a marginal population) under genetically
realistic assumptions. Analyses of this sort are important because small isolated
populations, are repeatedly affected by complex interactions between ecological
and evolutionary processes, which can lead to their death. Understanding these
interactions can therefore provide an insight into the conditions under which
extinction risk can be mitigated in peripheral populations thus, contributing
to conservation and restoration efforts.\r\n\r\nChapter 5 extends the analysis
in chapter 4 to consider the dynamics of load (due to deleterious mutation accumulation)
and extinction risk in a metapopulation. We explore the role of gene flow, selection,
and dominance on load and extinction risk and further pinpoint critical thresholds
required for metapopulation persistence.\r\n\r\nOverall this research contributes
to our understanding of ecological and evolutionary mechanisms that shape species’
persistence in fragmented landscapes, a crucial foundation for successful conservation
efforts and biodiversity management."

text: Redox flow batteries (RFBs) rely on the development of cheap, highly soluble,
and high-energy-density electrolytes. Several candidate quinones have already
been investigated in the literature as two-electron anolytes or catholytes, benefiting
from fast kinetics, high tunability, and low cost. Here, an investigation of nitrogen-rich
fused heteroaromatic quinones was carried out to explore avenues for electrolyte
development. These quinones were synthesized and screened by using electrochemical
techniques. The most promising candidate, 4,8-dioxo-4,8-dihydrobenzo[1,2-d:4,5-d′]bis([1,2,3]triazole)-1,5-diide
(−0.68 V(SHE)), was tested in both an asymmetric and symmetric full-cell setup
resulting in capacity fade rates of 0.35% per cycle and 0.0124% per cycle, respectively.
In situ ultraviolet-visible spectroscopy (UV–Vis), nuclear magnetic resonance
(NMR), and electron paramagnetic resonance (EPR) spectroscopies were used to investigate
the electrochemical stability of the charged species during operation. UV–Vis
spectroscopy, supported by density functional theory (DFT) modeling, reaffirmed
that the two-step charging mechanism observed during battery operation consisted
of two, single-electron transfers. The radical concentration during battery operation
and the degree of delocalization of the unpaired electron were quantified with
NMR and EPR spectroscopy.

text: Developing cost-effective and high-performance thermoelectric (TE) materials
to assemble efficient TE devices presents a multitude of challenges and opportunities.
Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant
elements. However, the challenge lies in its poor electrical conductivity. Herein,
an efficient and scalable solution-based approach is developed to synthesize high-quality
Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement
and annealing treatments, the dried powders are consolidated into dense pellets,
and their TE properties are investigated. Pb doping effectively increases the
charge carrier concentration, resulting in a significant increase in electrical
conductivity, while the Seebeck coefficients remain consistently high. The calculated
band structure shows that Pb doping induces band convergence, thereby increasing
the effective mass. Furthermore, the large ionic radius of Pb2+ results in the
generation of additional point and plane defects and interphases, dramatically
enhancing phonon scattering, which significantly decreases the lattice thermal
conductivity at high temperatures. Overall, a maximum figure of merit (zTmax)
≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold
increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based
materials produced by solid-state, demonstrating advantages of versatility and
cost-effectiveness using a solution-based technology.
