text: The short history of research on Li-O2 batteries has seen a remarkable number
of mechanistic U-turns over the years. From the initial use of carbonate electrolytes,
that were then found to be entirely unsuitable, to the belief that (su)peroxide
was solely responsible for degradation, before the more reactive singlet oxygen
was found to form, to the hypothesis that capacity depends on a competing surface/solution
mechanism before a practically exclusive solution mechanism was identified. Herein,
we argue for an ever-fresh look at the reported data without bias towards supposedly
established explanations. We explain how the latest findings on rate and capacity
limits, as well as the origin of side reactions, are connected via the disproportionation
(DISP) step in the (dis)charge mechanism. Therefrom, directions emerge for the
design of electrolytes and mediators on how to suppress side reactions and to
enable high rate and high reversible capacity.

text: We present a discretization of the dynamic optimal transport problem for which
we can obtain the convergence rate for the value of the transport cost to its
continuous value when the temporal and spatial stepsize vanish. This convergence
result does not require any regularity assumption on the measures, though experiments
suggest that the rate is not sharp. Via an analysis of the duality gap we also
obtain the convergence rates for the gradient of the optimal potentials and the
velocity field under mild regularity assumptions. To obtain such rates we discretize
the dual formulation of the dynamic optimal transport problem and use the mature
literature related to the error due to discretizing the Hamilton-Jacobi equation.

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.

text: "Understanding the relationship between a given phenotype and its underlying
genotype or genotypes is one of the most pressing challenges of biology, as it
lies at the heart of not only basic understanding of evolutionary theory, but
also of practical applications in medicine and bioengineering. Understanding this
relationship is complicated by the ubiquitous phenomenon of epistasis, wherein
mutation effects are dependent on their genetic context. Fitness landscapes —
representations of phenotype as a function of genotype — are being increasingly
used as a tool to study the effects and interactions of thousands of mutations,
but are experimentally limited to exploring a small fraction of a protein’s theoretical
sequence space. Furthermore, not all regions of said sequence space are necessarily
equally informative. Thus, gene selection for landscape surveys should be carefully
considered in order to maximize the usable output of necessarily limited data.\r\n\r\nIn
this work, we analyzed the fitness landscapes of orthologous green fluorescent
proteins from four different species, by systematically measuring the phenotype,
fluorescence, of tens of thousands of mutant genotypes from each protein. These
landscapes were highly heterogeneous, with some genes being mutationally robust
and displaying epistasis only rarely, and others being highly epistatic and mutationally
fragile. We used this data to train machine learning models to predict fluorescence
from genotype. Although the training data contained almost exclusively genotypes
with less than 3% sequence divergence from the original wild-type sequences, we
were able to create novel, functional genotypes with up to 20% sequence divergence.
Counterintuitively however, genes with high mutational robustness and rare epistasis
were more difficult to introduce large numbers of mutations into, not less. This
represents the first study of large-scale fitness landscapes of a protein family,
and provides insights into how to approach future landscape surveys and their
applications in novel protein design."

text: 'The formation of new ribosomes is tightly coordinated with cell growth and
proliferation. In eukaryotes, the correct assembly of all ribosomal proteins and
RNAs follows an intricate scheme of maturation and rearrangement steps across
three cellular compartments: the nucleolus, nucleoplasm, and cytoplasm. We demonstrate
that usnic acid, a lichen secondary metabolite, inhibits the maturation of the
large ribosomal subunit in yeast. We combine biochemical characterization of pre-ribosomal
particles with a quantitative single-particle cryo-EM approach to monitor changes
in nucleolar particle populations upon drug treatment. Usnic acid rapidly blocks
the transition from nucleolar state B to C of Nsa1-associated pre-ribosomes, depleting
key maturation factors such as Dbp10 and hindering pre-rRNA processing. This primary
nucleolar block rapidly rebounds on earlier stages of the pathway which highlights
the regulatory linkages between different steps. In summary, we provide an in-depth
characterization of the effect of usnic acid on ribosome biogenesis, which may
have implications for its reported anti-cancer activities.'

text: 'Thin pancake-like neuronal networks cultured on top of a planar microelectrode
array have been extensively tried out in neuroengineering, as a substrate for
the mobile robot’s control unit, i.e., as a cyborg’s brain. Most of these attempts
failed due to intricate self-organizing dynamics in the neuronal systems. In particular,
the networks may exhibit an emergent spatial map of steady nucleation sites (“n-sites”)
of spontaneous population spikes. Being unpredictable and independent of the surface
electrode locations, the n-sites drastically change local ability of the network
to generate spikes. Here, using a spiking neuronal network model with generative
spatially-embedded connectome, we systematically show in simulations that the
number, location, and relative activity of spontaneously formed n-sites (“the
vitals”) crucially depend on the samplings of three distributions: (1) the network
distribution of neuronal excitability, (2) the distribution of connections between
neurons of the network, and (3) the distribution of maximal amplitudes of a single
synaptic current pulse. Moreover, blocking the dynamics of a small fraction (about
4%) of non-pacemaker neurons having the highest excitability was enough to completely
suppress the occurrence of population spikes and their n-sites. This key result
is explained theoretically. Remarkably, the n-sites occur taking into account
only short-term synaptic plasticity, i.e., without a Hebbian-type plasticity.
As the spiking network model used in this study is strictly deterministic, all
simulation results can be accurately reproduced. The model, which has already
demonstrated a very high richness-to-complexity ratio, can also be directly extended
into the three-dimensional case, e.g., for targeting peculiarities of spiking
dynamics in cerebral (or brain) organoids. We recommend the model as an excellent
illustrative tool for teaching network-level computational neuroscience, complementing
a few benchmark models.'

text: We show convergence of the Navier-Stokes/Allen-Cahn system to a classical
sharp interface model for the two-phase flow of two viscous incompressible fluids
with same viscosities in a smooth bounded domain in two and three space dimensions
as long as a smooth solution of the limit system exists. Moreover, we obtain error
estimates with the aid of a relative entropy method. Our results hold provided
that the mobility mε>0 in the Allen-Cahn equation tends to zero in a subcritical
way, i.e., mε=m0εβ for some β∈(0,2) and m0>0 . The proof proceeds by showing
via a relative entropy argument that the solution to the Navier-Stokes/Allen-Cahn
system remains close to the solution of a perturbed version of the two-phase flow
problem, augmented by an extra mean curvature flow term mεHΓt in the interface
motion. In a second step, it is easy to see that the solution to the perturbed
problem is close to the original two-phase flow.

text: "Context: Biotic resource exploitation is a critical determinant of species’
distributions. However, quantifying resource exploitation patterns through space
and time can be difficult, complicating their incorporation in spatial ecology
studies. Therefore, understanding the local drivers of spatial patterns of resource
exploitation may contribute to better large-scale species distribution models.\r\nObjectives:
We investigated (1) how the resource exploitation patterns of two trophic interactions
(plant–insect) are explained by insect behaviour, resource aggregation, and potential
insect-insect interactions. We also analyzed how (2) resource patch size and (3)
resource accessibility in a heterogeneous landscape affected host exploitation
patterns.\r\nMethods: We quantified nectar robbing by insects in the genus Bombus
(bumblebees) and seed predation by Brachypterolus vestitus larvae (Antirrhinum
beetle) on Antirrhinum majus L. (wild snapdragons) in the Pyrenees Mountains,
Catalonia, Spain. We tested hypotheses about resource exploitation by integrating
spatial analyses at multiple scales.\r\nResults: Both trophic interactions were
aggregated, explained by the aggregation of their resource. At some scales, nectar
robbing is more aggregated than the resource. Trophic interaction abundance is
proportional to resource patch size, following the ideal free distribution model.
Landscape features do not explain the locations exploited. Nectar robbing and
seed predation occur together more often than expected.\r\nConclusions: Our findings
suggest that multiple biotic and ecological spatial factors may simultaneously
affect resource exploitation at a local scale. These findings should be considered
when developing agricultural projects, management plans and conservation policies."

text: The increasingly neutral intergalactic gas at z > 6 impacts the Lyman-α (Lyα)
flux observed from galaxies. One luminous galaxy, COLA1, stands out because of
its unique double-peaked Lyα line at z = 6.6, unseen in any simulation of reionization.
Here, we present JWST/NIRCam wide-field slitless spectroscopy in a 21 arcmin2
field centered on COLA1. We find 141 galaxies spectroscopically selected through
the [O III] doublet at 5.35 < z < 6.95, with 40 of these sources showing Hβ. For
COLA1, we additionally detect [O III]4363 as well as Hγ. We measure a systemic
redshift of z = 6.5917 for COLA1, confirming the classical double-peak nature
of the Lyα profile. This implies that it resides in a highly ionized bubble and
that it is leaking ionizing photons with a high escape fraction of fesc(LyC) = 20–50%,
making it a prime laboratory to study Lyman continuum escape in the Epoch of Reionization.
COLA1 shows all the signs of a prolific ionizer with a Lyα escape fraction of
81 ± 5%, Balmer decrement indicating no dust, a steep UV slope (βUV = −3.2 ± 0.4),
and a star-formation surface density ≳10× that of typical galaxies at similar
redshift. We detect five galaxies in COLA1’s close environment (Δz < 0.02). Exploiting
the high spectroscopic completeness inherent to grism surveys, and using mock
simulations that fully mimic the selection function, we show that the number of
detected companions is very typical for a normal similarly UV-bright (MUV ∼ −21.3)
galaxy – that is, the ionized bubble around COLA1 is unlikely to be due to an
excessively large over-density. Instead, the measured ionizing properties suggest
that COLA1 by itself might be powering the bubble required to explain its double-peaked
Lyα profile (Rion ≈ 0.7 pMpc), with only minor contributions from detected neighbors
(−19.5 ≲ MUV ≲ −17.5).

text: "Abstract\r\nMethods used in topological data analysis naturally capture higher-order
interactions in point cloud data embedded in a metric space. This methodology
was recently extended to data living in an information space, by which we mean
a space measured with an information theoretical distance. One such setting is
a finite collection of discrete probability distributions embedded in the probability
simplex measured with the relative entropy (Kullback–Leibler divergence). More
generally, one can work with a Bregman divergence parameterized by a different
notion of entropy. While theoretical algorithms exist for this setup, there is
a paucity of implementations for exploring and comparing geometric-topological
properties of various information spaces. The interest of this work is therefore
twofold. First, we propose the first robust algorithms and software for geometric
and topological data analysis in information space. Perhaps surprisingly, despite
working with Bregman divergences, our design reuses robust libraries for the Euclidean
case. Second, using the new software, we take the first steps towards understanding
the geometric-topological structure of these spaces. In particular, we compare
them with the more familiar spaces equipped with the Euclidean and Fisher metrics."

text: "Enzyme-substrate kinetics form the basis of many biomolecular processes.
The interplay between substrate binding and substrate geometry can give rise to
long-range interactions between enzyme binding events. Here we study a general
model of enzyme-substrate kinetics with restricted long-range interactions described
by an exponent −\U0001D6FE. We employ a coherent-state path integral and renormalization
group approach to calculate the first moment and two-point correlation function
of the enzyme-binding profile. We show that starting from an empty substrate the
average occupancy follows a power law with an exponent 1/(1−\U0001D6FE) over time.
The correlation function decays algebraically with two distinct spatial regimes
characterized by exponents −\U0001D6FE on short distances and −(2/3)(2−\U0001D6FE)
on long distances. The crossover between both regimes scales inversely with the
average substrate occupancy. Our work allows associating experimental measurements
of bound enzyme locations with their binding kinetics and the spatial conformation
of the substrate."

text: Strong data processing inequalities (SDPI) are an important object of study
in Information Theory and have been well studied for f -divergences. Universal
upper and lower bounds have been provided along with several applications, connecting
them to impossibility (converse) results, concentration of measure, hypercontractivity,
and so on. In this paper, we study Renyi divergence and the corresponding SDPI
constant whose behavior seems to deviate from that of ordinary <1>-divergences.
In particular, one can find examples showing that the universal upper bound relating
its SDPI constant to the one of Total Variation does not hold in general. In this
work, we prove, however, that the universal lower bound involving the SDPI constant
of the Chi-square divergence does indeed hold. Furthermore, we also provide a
characterization of the distribution that achieves the supremum when is equal
to 2 and consequently compute the SDPI constant for Renyi divergence of the general
binary channel.

text: 'Sibson''s α -mutual information has received renewed attention recently in
several contexts: concentration of measure under dependence, statistical learning,
hypothesis testing, and estimation theory. In this work, we introduce several
variational representations of Sibson''s α -mutual information: 1) as a supremum
over joint distributions of (a combination of) KL divergences; and 2) as a supremum
over functions of opportune expected values. Leveraging them, we produce a variety
of novel and known results, including a generalization of transportation-cost
inequalities and Fano''s inequality.'

text: We propose a concatenated code construction for a class of discrete-alphabet
oblivious arbitrarily varying channels (AVCs) with cost constraints. The code
has time and space complexity polynomial in the blocklength n . It uses a Reed-Solomon
outer code, logarithmic blocklength random inner codes, and stochastic encoding
by permuting the codeword before transmission. When the channel satisfies a condition
called strong DS-nonsymmetrizability (a modified version of nonsymmetrizability
originally due to Dobrushin and Stambler), we show that the code achieves a rate
that for a variety of oblivious AVCs (such as classically studied error/erasure
channels) match the known capacities.

text: Broadband photodetectors that can decipher the wavelength (λ) and intensity
(I) of an unknown incident light are urgently demanded. Photothermoelectric (PTE)
detectors can achieve ultrabroadband photodetection surpassing the bandgap limitation;
however, their practical application is severely hampered by the lack of deciphering
strategy. In this work, we report a variable elimination method to decipher λ
and I of the incident lights based on an integrated Ag2Se film-based PTE detector.
Nanostructured Ag2Se films with controlled thickness are synthesized using an
ion sputtering of Ag and a room-temperature selenization method and then assembled
into a detector. Under identical illumination, Ag2Se films of different thicknesses
produce varying output photothermal voltages, influenced by factors including
λ. By establishing a direct relationship between the photothermal voltage and
the absorption of Ag2Se films of varied thickness, we successfully eliminate variables
independent of λ, thus determining λ. Subsequently, I is determined by the calibrated
responsivity relationship using obtained λ. Our PTE detector achieves a broadband
spectrum from 400 to 950 nm and high accuracy, with deviations as low as ∼2.63
and ∼0.53% for deciphered λ and I, respectively. This method allows for self-powered
broadband decipherable photodetection without a complex device architecture or
computational assistance, which could boost the research enthusiasm and promote
the commercialization of PTE broadband detectors.
