text: 'Markov decision processes (MDPs) provide a standard framework for sequential
decision making under uncertainty. However, MDPs do not take uncertainty in transition
probabilities into account. Robust Markov decision processes (RMDPs) address this
shortcoming of MDPs by assigning to each transition an uncertainty set rather
than a single probability value. In this work, we consider polytopic RMDPs in
which all uncertainty sets are polytopes and study the problem of solving long-run
average reward polytopic RMDPs. We present a novel perspective on this problem
and show that it can be reduced to solving long-run average reward turn-based
stochastic games with finite state and action spaces. This reduction allows us
to derive several important consequences that were hitherto not known to hold
for polytopic RMDPs. First, we derive new computational complexity bounds for
solving long-run average reward polytopic RMDPs, showing for the first time that
the threshold decision problem for them is in NP∩CONP and that they admit a randomized
algorithm with sub-exponential expected runtime. Second, we present Robust Polytopic
Policy Iteration (RPPI), a novel policy iteration algorithm for solving long-run
average reward polytopic RMDPs. Our experimental evaluation shows that RPPI is
much more efficient in solving long-run average reward polytopic RMDPs compared
to state-of-the-art methods based on value iteration. '

text: 'Holdase chaperones are essential in the mitochondrial membrane-protein biogenesis
as they stabilize preproteins and keep them in an import-competent state as they
travel through the aqueous cytosol and intermembrane space. The small TIM chaperones
of the mitochondrial intermembrane space function within a fine balance of client
promiscuity and high affinity binding, while being also able to release their
client proteins without significant energy barrier to the downstream insertases/translocases.
The tendency of the preproteins to aggregate and the dynamic nature of the preprotein—chaperone
complexes makes the preparation of these complexes challenging. Here we present
two optimized methods for complex formation of highly hydrophobic precursor proteins
and chaperones: a pull-down approach and an in-vitro translation strategy. In
the former, attaching the client protein to an affinity resin keeps the individual
client protein copies apart from each other and decreases the client self-aggregation
probability, thereby favouring complex formation. In the latter approach, a purified
chaperone, added to the cell-free protein synthesis, captures the nascent precursor
protein. The choice of method will depend on the desired client-chaperone complex
amount, or the need for specific labeling scheme.'

text: 'Despite the considerable interest in the recombinant production of synthetic
spider silk fibers that possess mechanical properties similar to those of native
spider silks, such as the cost-effectiveness, tunability, and scalability realization,
is still lacking. To address this long-standing challenge, we have constructed
an artificial spider silk gene using Golden Gate assembly for the recombinant
bacterial production of dragline-mimicking silk, incorporating all the essential
components: the N-terminal domain, a 33-residue-long major-ampullate-spidroin-inspired
segment repeated 16 times, and the C-terminal domain (N16C). This designed silk-like
protein was successfully expressed in Escherichia coli, purified, and cast into
films from formic acid. We produced uniformly 13C–15N-labeled N16C films and employed
solid-state magic-angle spinning nuclear magnetic resonance (NMR) for characterization.
Thus, we could demonstrate that our bioengineered silk-like protein self-assembles
into a film where, when hydrated, the solvent-exposed layer of the rigid, β-nanocrystalline
polyalanine core undergoes a transition to an α-helical structure, gaining mobility
to the extent that it fully dissolves in water and transforms into a highly dynamic
random coil. This hydration-induced behavior induces chain dynamics in the glycine-rich
amorphous soft segments on the microsecond time scale, contributing to the elasticity
of the solid material. Our findings not only reveal the presence of structurally
and dynamically distinct segments within the film’s superstructure but also highlight
the complexity of the self-organization responsible for the exceptional mechanical
properties observed in proteins that mimic dragline silk.'

text: Defense against pathogens and parasites requires substantial investment of
energy and resources on part of the host. This makes the host immune function
dependent on availability and accessibility of resources. A resource deprived
host is therefore expected to be more susceptible to infections, although empirical
results do not always align with this prediction. Limiting host access to resources
can additionally impact within-host pathogen numbers, either directly by altering
the amount of resources available to the pathogens for proliferation or indirectly
by altering the efficiency of the host immune system. We tested for the effects
of host starvation (complete deprivation of resources) on susceptibility to bacterial
pathogens, and within-host pathogen proliferation, in Drosophila melanogaster
females. Our results show that starvation increases post-infection mortality of
the host, but in a pathogen-specific manner. This increase in mortality is always
accompanied by increased within-host pathogen proliferation. We therefore propose
that starvation compromises host resistance to bacterial infections in Drosophila
melanogaster females thereby increasing susceptibility to infections.

text: Red Giant stars host solar-like oscillations which have mixed character, being
sensitive to conditions both in the outer convection zone and deep within the
interior. The properties of these modes are sensitive to both core rotation and
magnetic fields. While asteroseismic studies of the former have been done on a
large scale, studies of the latter are currently limited to tens of stars. We
aim to produce the first large catalogue of both magnetic and rotational perturbations.
We jointly constrain these parameters by devising an automated method for fitting
the power spectra directly. We successfully apply the method to 302 low-luminosity
red giants. We find a clear bimodality in core rotation rate. The primary peak
is at δνrot = 0.32 μHz, and the secondary at δνrot = 0.47 μHz. Combining our results
with literature values, we find that the percentage of stars rotating much more
rapidly than the population average increases with evolutionary state. We measure
magnetic splittings of 2σ significance in 23 stars. While the most extreme magnetic
splitting values appear in stars with masses > 1.1M⊙, implying they formerly hosted
a convective core, a small but statistically significant magnetic splitting is
measured at lower masses. Asymmetry between the frequencies of a rotationally
split multiplet has previously been used to diagnose the presence of a magnetic
perturbation. We find that of the stars with a significant detection of magnetic
perturbation, 43\% do not show strong asymmetry. We find no strong evidence of
correlation between the rotation and magnetic parameters.

text: We investigate the phase ordering (pattern formation) of systems of two-dimensional
core–shell particles using Monte Carlo (MC) computer simulations and classical
density functional theory (DFT). The particles interact via a pair potential having
a hard core and a repulsive square shoulder. Our simulations show that on cooling,
the liquid state structure becomes increasingly characterized by long wavelength
density modulations and on further cooling forms a variety of other phases, including
clustered, striped, and other patterned phases. In DFT, the hard core part of
the potential is treated using either fundamental measure theory or a simple local
density approximation, whereas the soft shoulder is treated using the random phase
approximation. The different DFTs are benchmarked using large-scale grand-canonical-MC
and Gibbs-ensemble-MC simulations, demonstrating their predictive capabilities
and shortcomings. We find that having the liquid state static structure factor
S(k) for wavenumber k is sufficient to identify the Fourier modes governing both
the liquid and solid phases. This allows us to identify from easier-to-obtain
liquid state data the wavenumbers relevant to the periodic phases and to predict
roughly where in the phase diagram these patterned phases arise.

text: Large-scale software repositories are a source of insights for software engineering.
They offer an unmatched window into the software development process at scale.
Their sheer number and size holds the promise of broadly applicable results. At
the same time, that very size presents practical challenges for scaling tools
and algorithms to millions of projects. A reasonable approach is to limit studies
to representative samples of the population of interest. Broadly applicable conclusions
can then be obtained by generalizing to the entire population. The contribution
of this paper is a standardized experimental design methodology for choosing the
inputs of studies working with large-scale repositories. We advocate for a methodology
that clearly lays out what the population of interest is, how to sample it, and
that fosters reproducibility. Along the way, we discourage researchers from using
extrinsic attributes of projects such as stars, that measure some unclear notion
of popularity.

text: Introducing a class of SU(2) invariant quantum unitary circuits generating
chiral transport, we examine the role of broken space-reflection and time-reversal
symmetries on spin-transport properties. Upon adjusting parameters of local unitary
gates, the dynamics can be either chaotic or integrable. The latter corresponds
to a generalization of the space-time discretized (Trotterized) higher-spin quantum
Heisenberg chain. We demonstrate that breaking of space-reflection symmetry results
in a drift in the dynamical spin susceptibility. Remarkably, we find a universal
drift velocity given by a simple formula, which, at zero average magnetization,
depends only on the values of SU(2) Casimir invariants associated with local spins.
In the integrable case, the drift velocity formula is confirmed analytically based
on the exact solution of thermodynamic Bethe ansatz equations. Finally, by inspecting
the large fluctuations of the time-integrated current between two halves of the
system in stationary maximum-entropy states, we demonstrate violation of the Gallavotti-Cohen
symmetry, implying that such states cannot be regarded as equilibrium ones. We
show that the scaled cumulant generating function of the time-integrated current
instead obeys a generalized fluctuation relation.

text: It is widely believed that information storage in neuronal circuits involves
nanoscopic structural changes at synapses, resulting in the formation of synaptic
engrams. However, direct evidence for this hypothesis is lacking. To test this
conjecture, we combined chemical potentiation, functional analysis by paired pre-postsynaptic
recordings, and structural analysis by electron microscopy (EM) and freeze-fracture
replica labeling (FRL) at the murine hippocampal mossy fiber synapse, a key synapse
in the trisynaptic circuit of the hippocampus. Biophysical analysis of synaptic
transmission revealed that forskolin-induced chemical potentiation increased the
readily releasable vesicle pool size and vesicular release probability by 146%
and 49%, respectively. Structural analysis of mossy fiber synapses by EM and FRL
demonstrated an increase in the number of vesicles close to the plasma membrane
and the number of clusters of the priming protein Munc13-1, indicating an increase
in the number of both docked and primed vesicles. Furthermore, FRL analysis revealed
a significant reduction of the distance between Munc13-1 and CaV2.1 Ca2+ channels,
suggesting reconfiguration of the channel-vesicle coupling nanotopography. Our
results indicate that presynaptic plasticity is associated with structural reorganization
of active zones. We propose that changes in potential nanoscopic organization
at synaptic vesicle release sites may be correlates of learning and memory at
a plastic central synapse.

text: Physics simulation in computer graphics can bring triangle meshes into topologically
invalid states. The method in this thesis contributed to Heiss-Synak* and Kalinov*
et al. [2024] who devised a non-manifold hybrid surface tracker—a surface tracker
that repairs explicit non-manifold triangle meshes with the help of the implicit
domain. Specifically, this thesis provides an algorithm for filling the holes
that are left after removing problematic parts of the mesh.

text: Motor circuits represent the main output of the central nervous system and
produce dynamic behaviors ranging from relatively simple rhythmic activities like
swimming in fish and breathing in mammals to highly sophisticated dexterous movements
in humans. Despite decades of research, the development and function of motor
circuits remain poorly understood. Breakthroughs in the field recently provided
new tools and tractable model systems that set the stage to discover the molecular
mechanisms and circuit logic underlying motor control. Here, we describe recent
advances from both vertebrate (mouse, frog) and invertebrate (nematode, fruit
fly) systems on cellular and molecular mechanisms that enable motor circuits to
develop and function and highlight conserved and divergent mechanisms necessary
for motor circuit development.

text: Neutral sodium (Na i) is an alkali metal with a favorable absorption cross
section such that tenuous gases are easily illuminated at select transiting exoplanet
systems. We examine both the time-averaged and time-series alkali spectral flux
individually, over 4 nights at a hot Saturn system on a ∼2.8 day orbit about a
Sun-like star WASP-49 A. Very Large Telescope/ESPRESSO observations are analyzed,
providing new constraints. We recover the previously confirmed residual sodium
flux uniquely when averaged, whereas night-to-night Na i varies by more than an
order of magnitude. On HARPS/3.6 m Epoch II, we report a Doppler redshift at vΓ,NaD
= + 9.7 ± 1.6 km s−1 with respect to the planet's rest frame. Upon examining the
lightcurves, we confirm night-to-night variability, on the order of ∼1%–4% in
NaD, rarely coinciding with exoplanet transit, not readily explained by stellar
activity, starspots, tellurics, or the interstellar medium. Coincident with the
∼+10 km s−1 Doppler redshift, we detect a transient sodium absorption event dFNaD/F⋆
= 3.6% ± 1% at a relative difference of ΔFNaD(t) ∼ 4.4% ± 1%, lasting ΔtNaD ≳
40 minutes. Since exoplanetary alkali signatures are blueshifted due to the natural
vector of radiation pressure, estimated here at roughly ∼−5.7 km s−1, the radial
velocity is rather at +15.4 km s−1, far larger than any known exoplanet system.
Given that the redshift magnitude vΓ is in between the Roche limit and dynamically
stable satellite orbits, the transient sodium may be a putative indication of
a natural satellite orbiting WASP-49 A b.

text: We study in this paper the problem of maintaining a solution to k-median and
k-means clustering in a fully dynamic setting. To do so, we present an algorithm
to efficiently maintain a coreset, a compressed version of the dataset, that allows
easy computation of a clustering solution at query time. Our coreset algorithm
has near-optimal update time of Õ(k) in general metric spaces, which reduces to
Õ(d) in the Euclidean space ℝ^d. The query time is O(k²) in general metrics, and
O(kd) in ℝ^d. To maintain a constant-factor approximation for k-median and k-means
clustering in Euclidean space, this directly leads to an algorithm with update
time Õ(d), and query time Õ(kd + k²). To maintain a O(polylog k)-approximation,
the query time is reduced to Õ(kd).

text: 'The problem of designing connectivity oracles supporting vertex failures
is one of the basic data structures problems for undirected graphs. It is already
well understood: previous works [Duan-Pettie STOC''10; Long-Saranurak FOCS''22]
achieve query time linear in the number of failed vertices, and it is conditionally
optimal as long as we require preprocessing time polynomial in the size of the
graph and update time polynomial in the number of failed vertices. We revisit
this problem in the paradigm of algorithms with predictions: we ask if the query
time can be improved if the set of failed vertices can be predicted beforehand
up to a small number of errors. More specifically, we design a data structure
that, given a graph G = (V,E) and a set of vertices predicted to fail D̂ ⊆ V of
size d = |D̂|, preprocesses it in time Õ(d|E|) and then can receive an update
given as the symmetric difference between the predicted and the actual set of
failed vertices D̂△D = (D̂ ⧵ D) ∪ (D ⧵ D̂) of size η = |D̂△D|, process it in time
Õ(η⁴), and after that answer connectivity queries in G ⧵ D in time O(η). Viewed
from another perspective, our data structure provides an improvement over the
state of the art for the fully dynamic subgraph connectivity problem in the sensitivity
setting [Henzinger-Neumann ESA''16]. We argue that the preprocessing time and
query time of our data structure are conditionally optimal under standard fine-grained
complexity assumptions.'

text: Local wound signaling in plants informs the surrounding tissues about an injury
and initiates the regeneration process. In a recent paper published in Cell, Yang
and colleagues show the involvement of a single Pep family member from tomato
in wound signaling and how exogenous application of this regeneration factor enhances
transformation efficiency in crops.

text: "In [KW06] Kapustin and Witten conjectured that there is a mirror symmetry
relation between\r\nthe hyperkähler structures on certain Higgs bundle moduli
spaces. As a consequence, they\r\nconjecture an equivalence between categories
of BBB and BAA-branes. At the classical\r\nlevel, this mirror symmetry is given
by T-duality between semi-flat hyperkähler structures on\r\nalgebraic integrable
systems.\r\nIn this thesis, we investigate the T-duality relation between hyperkähler
structures and the\r\ncorresponding branes on affine torus bundles. We use the
techniques of generalized geometry\r\nto show that semi-flat hyperkähler structures
are T-dual on algebraic integrable systems.\r\nWe also describe T-duality for
generalized branes. Motivated by Fourier-Mukai transform\r\nwe upgrade the T-duality
between generalized branes to T-duality of submanifolds endowed\r\nwith U(1)-bundles
and connections. This T-duality in the appropriate context specializes to\r\nT-duality
between BBB and BAA-branes.\r\n"

text: Characterizing the prevalence and properties of faint active galactic nuclei
(AGNs) in the early Universe is key for understanding the formation of supermassive
black holes (SMBHs) and determining their role in cosmic reionization. We perform
a spectroscopic search for broad Hα emitters at z ≈ 4–6 using deep JWST/NIRCam
imaging and wide field slitless spectroscopy from the EIGER and FRESCO surveys.
We identify 20 Hα lines at z = 4.2–5.5 that have broad components with line widths
from ∼1200–3700 km s−1, contributing ∼30%–90% of the total line flux. We interpret
these broad components as being powered by accretion onto SMBHs with implied masses
∼107–8M⊙. In the UV luminosity range MUV,AGN+host = −21 to −18, we measure number
densities of ≈10−5 cMpc−3. This is an order of magnitude higher than expected
from extrapolating quasar UV luminosity functions (LFs). Yet, such AGN are found
in only <1% of star-forming galaxies at z ∼ 5. The number density discrepancy
is much lower when compared to the broad Hα LF. The SMBH mass function agrees
with large cosmological simulations. In two objects, we detect complex Hα profiles
that we tentatively interpret as caused by absorption signatures from dense gas
fueling SMBH growth and outflows. We may be witnessing early AGN feedback that
will clear dust-free pathways through which more massive blue quasars are seen.
We uncover a strong correlation between reddening and the fraction of total galaxy
luminosity arising from faint AGN. This implies that early SMBH growth is highly
obscured and that faint AGN are only minor contributors to cosmic reionization.

text: The recently discovered Pa 30 nebula, the putative type Iax supernova remnant
associated with the historical supernova of 1181 AD, shows puzzling characteristics
that make it unique among known supernova remnants. In particular, Pa 30 exhibits
a complex morphology, with a unique radial and filamentary structure, and it hosts
a hot stellar remnant at its center, which displays oxygen-dominated, ultrafast
winds. Because of the surviving stellar remnant and the lack of hydrogen and helium
in its filaments, it has been suggested that Pa 30 is the product of a failed
thermonuclear explosion in a near- or super-Chandrasekhar white dwarf, which created
a subluminous transient, a rare subtype of the Ia class of supernovae called type
Iax. We present here a detailed study of the 3D structure and velocities of a
full radial section of the remnant. The Integral Field Unit observations, obtained
with the new red channel of the Keck Cosmic Web Imager spectrograph, reveal that
the ejecta are consistent with being ballistic, with velocities close to the free-expansion
velocity. Additionally, we detect a large cavity inside the supernova remnant
and a sharp inner edge to the filamentary structure, which coincides with the
outer edge of a bright ring detected in infrared images. Finally, we detect a
strong asymmetry in the amount of ejecta along the line of sight, which might
hint at an asymmetric explosion. Our analysis provides strong confirmation that
the explosion originated from SN 1181.
