text: High-entropy materials (HEMs) offer a quasi-continuous spectrum of active
sites and have generated great expectations in fields such as electrocatalysis
and energy storage. Despite their potential, the complex composition and associated
surface phenomena of HEMs pose challenges to their rational design and development.
In this context, we have synthesized FeCoNiPdWP high entropy phosphide (HEP) nanoparticles
using a low-temperature colloidal method, and explored their application as bifunctional
electrocatalysts for the oxygen evolution and reduction reactions (OER/ORR). Our
analysis provides a detailed understanding of the individual roles and transformations
of each element during OER/ORR operation. Notably, the HEPs exhibit an exceptionally
low OER overpotential of 227 mV at 10 mA cm−2, attributed to the reconstructed
HEP surface into a FeCoNiPdW high entropy oxyhydroxide with high oxidation states
of Fe, Co, and Ni serving as the active sites. Additionally, Pd and W play crucial
roles in modulating the electronic structure to optimize the adsorption energy
of oxygen intermediates. For the ORR, Pd emerges as the most active component.
In the reconstructed catalyst, the strong d–d orbital coupling of especially Pd,
Co, and W fine-tunes ORR electron transfer pathways, delivering an ORR half-wave
potential of 0.81 V with a pure four-electron reduction mechanism. The practicality
of these HEPs catalysts is showcased through the assembly of aqueous zinc–air
batteries. These batteries demonstrate a superior specific capacity of 886 mA
h gZn−1 and maintain excellent stability over more than 700 hours of continuous
operation. Overall, this study not only elucidates the role of each element in
HEMs but also establishes a foundational framework for the design and development
of next-generation bifunctional oxygen catalysts, broadening the potential applications
of these complex materials in advanced energy systems.

text: 'There is an ever-growing zoo of modern neural network models that can efficiently
learn end-to-end control from visual observations. These advanced deep models,
ranging from convolutional to Vision Transformers, from small to gigantic networks,
have been extensively tested on offline image classification tasks. In this paper,
we study these vision models with respect to the open-loop training to closed-loop
generalization abilities, i.e., deployment realizes a causal feedback loop that
is not present during training. This causality gap typically emerges in robotics
applications such as autonomous driving, where a network is trained to imitate
the control commands of a human. In this setting, two situations arise: 1) Closed-loop
testing in-distribution, where the test environment shares properties with those
of offline training data. 2) Closed-loop testing under distribution shifts and
out-of-distribution. Contrary to recently reported results, we show that under
proper training guidelines, all vision architectures perform indistinguishably
well on in-distribution deployment, resolving the causality gap. In situation
2, We observe that scale is the strongest factor in improving closed-loop generalization
regardless of the choice of the model architecture. Our results predict the trend
that in the future we will see larger and larger models being used in offline-training-online-deployment
imitation learning tasks in robotic applications.'

text: Sodium dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL)
is an electron microscope (EM) sample preparation technique which allows for high-resolution
visualization of membrane proteins with high sensitivity. However, image acquisition
of specific replica profiles such as synapses in a large field of EM view needs
a valid experience and a long time for manual searching. Here, we describe how
to utilize deep learning for automatizing image acquisition of specific profiles
of interest in replica samples. This protocol facilitates the labor-intensive
collection of EM images, in particular for rare profiles. We provide instructions
for using SerialEM image acquisition software in conjunction with object detection
by our newly developed deep learning software DarEM, to automatically acquire
tilt series of all synapses in a selected region. We then show how to perform
a mostly automated analysis of gold particle labeling in the acquired images by
utilizing Darea software.

text: DNA cloning is a core technique in biomedical and biotechnological research
and is used to assemble and modify DNA fragments at will. While DNA cloning has
traditionally relied on restriction enzymes, recent homology-based methods offer
improved protocols together with seamless and directional assembly of desired
products, overcoming the main disadvantages of restriction enzyme DNA cloning.
This chapter provides a historical perspective on DNA cloning, presents a detailed
discussion on state-of-the-art in vitro and in vivo homology-based methodologies,
covering the basics of how to perform all major plasmid modifications (sub-cloning,
site-directed mutagenesis, insertions, and deletions), and gives examples of how
to apply these techniques for complex DNA cloning projects.

text: The developmental plasticity of the root system plays an essential role in
the adaptation of plants to the environment. Among many other signals, auxin and
its directional, intercellular transport are critical in regulating root growth
and development. In particular, the PIN-FORMED2 (PIN2) auxin exporter acts as
a key regulator of root gravitropic growth. Multiple regulators have been reported
to be involved in PIN2-mediated root growth; however, our information remains
incomplete. Here, we identified ROWY Bro1-domain proteins as important regulators
of PIN2 sorting control. Genetic analysis revealed that Arabidopsis rowy1 single
mutants and higher-order rowy1 rowy2 rowy3 triple mutants presented a wavy root
growth phenotype. Cell biological experiments revealed that ROWY1 and PIN2 colocalized
to the apical side of the plasma membrane in the root epidermis and that ROWYs
are required for correct PM targeting of PIN2. In addition, ROWYs also affected
PIN3 protein abundance in the stele, suggesting the potential involvement of additional
PIN transporters as well as other proteins. A global transcriptome analysis revealed
that ROWY genes are involved in the Fe2+ availability perception pathway. This
work establishes ROWYs as important novel regulators of root gravitropic growth
by connecting micronutrient availability to the proper subcellular targeting of
PIN auxin transporters.

text: 'Graph games lie at the algorithmic core of many automated design problems
in computer science. These are games usually played between two players on a given
graph, where the players keep moving a token along the edges according to pre-determined
rules (turn-based, concurrent, etc.), and the winner is decided based on the infinite
path (aka play) traversed by the token from a given initial position. In bidding
games, the players initially get some monetary budgets which they need to use
to bid for the privilege of moving the token at each step. Each round of bidding
affects the players'' available budgets, which is the only form of update that
the budgets experience. We introduce bidding games with charging where the players
can additionally improve their budgets during the game by collecting vertex-dependent
monetary rewards, aka the "charges." Unlike traditional bidding games (where all
charges are zero), bidding games with charging allow non-trivial recurrent behaviors.
For example, a reachability objective may require multiple detours to vertices
with high charges to earn additional budget. We show that, nonetheless, the central
property of traditional bidding games generalizes to bidding games with charging:
For each vertex there exists a threshold ratio, which is the necessary and sufficient
fraction of the total budget for winning the game from that vertex. While the
thresholds of traditional bidding games correspond to unique fixed points of linear
systems of equations, in games with charging, these fixed points are no longer
unique. This significantly complicates the proof of existence and the algorithmic
computation of thresholds for infinite-duration objectives. We also provide the
lower complexity bounds for computing thresholds for Rabin and Streett objectives,
which are the first known lower bounds in any form of bidding games (with or without
charging), and we solve the following repair problem for safety and reachability
games that have unsatisfiable objectives: Can we distribute a given amount of
charge to the players in a way such that the objective can be satisfied?'

text: "An automaton \U0001D49C is history-deterministic if its nondeterminism can
be resolved on the fly, only using the prefix of the word read so far. This mild
form of nondeterminism has attracted particular attention for its applications
in synthesis problems. An automaton \U0001D49C is guidable with respect to a class
C of automata if it can fairly simulate every automaton in C, whose language is
contained in that of \U0001D49C. In other words, guidable automata are those for
which inclusion and simulation coincide, making them particularly interesting
for model-checking. We study the connection between these two notions, and specifically
the question of when they coincide. For classes of automata on which they do,
deciding guidability, an otherwise challenging decision problem, reduces to deciding
history-determinism, a problem that is starting to be well-understood for many
classes. We provide a selection of sufficient criteria for a class of automata
to guarantee the coincidence of the notions, and use them to show that the notions
coincide for the most common automata classes, among which are ω-regular automata
and many infinite-state automata with safety and reachability acceptance conditions,
including vector addition systems with states, one-counter nets, pushdown-, Parikh-,
and timed-automata. We also demonstrate that history-determinism and guidability
do not always coincide, for example, for the classes of timed automata with a
fixed number of clocks."

text: "We study the following refinement relation between nondeterministic state-transition
models: model ℬ strategically dominates model \U0001D49C iff every deterministic
refinement of \U0001D49C is language contained in some deterministic refinement
of ℬ. While language containment is trace inclusion, and the (fair) simulation
preorder coincides with tree inclusion, strategic dominance falls strictly between
the two and can be characterized as \"strategy inclusion\" between \U0001D49C
and ℬ: every strategy that resolves the nondeterminism of \U0001D49C is dominated
by a strategy that resolves the nondeterminism of ℬ. Strategic dominance can be
checked in 2-ExpTime by a decidable first-order Presburger logic with quantification
over words and strategies, called resolver logic. We give several other applications
of resolver logic, including checking the co-safety, co-liveness, and history-determinism
of boolean and quantitative automata, and checking the inclusion between hyperproperties
that are specified by nondeterministic boolean and quantitative automata."

text: We present results from the JWST First Reionization Epoch Spectroscopically
Complete Observations survey on the star-forming sequence (SFS) of galaxies at
1.0 < z < 1.7, around the peak of the cosmic star formation history. Star formation
rates (SFRs) are measured from the redshifted, relatively dust-insensitive Paschen-α
emission line, and stellar mass measurements include the F444W (4.4 μm; rest-frame
H) band. We find SFRs of galaxies with log(M*/M⊙) > 9.5 that are lower than found
in many earlier studies by up to 0.6 dex, but in good agreement with recent results
obtained with the Prospector fitting framework. The difference (log(SFR(Paα)-SFR(Prospector))
is −0.09 ± 0.04 dex at 1010−11M⊙. We also measure the empirical relation between
Paschen-α luminosity and rest-frame H-band magnitude and find that the scatter
is only 0.04 dex lower than that of the SFR–M* relation and is much lower than
the systematic differences among relations in the literature due to various methods
of converting observed measurements to physical properties. We additionally identify
examples of sources—that, with standard cutoffs via the UVJ diagram, would be
deemed quiescent—with significant (log(sSFR)> −11 yr−1), typically extended, Paschen-α
emission. Our results may be indicative of the potential unification of methods
used to derive the SFS with careful selection of star-forming galaxies and independent
SFR and stellar mass indicators.

text: Parallel SGD in a shared-memory setting is oft-represented by the popular
Hogwild! algorithm, in which lock-free updates are asynchronously performed by
multiple computing processes. Unfortunately, scaling Hogwild! to distributed workers
is largely unexplored. Specifically, it is unknown if any adaptation of Hogwild!
to the popular decentralized multi-GPU setting offers any competitive speedup,
either empirically or theoretically. In this work, we investigate the potential
of decentralizing Hogwild! by incorporating simultaneously (a) asynchronous local
gradient updates on the shared memory of GPUs, and (b) non-blocking asynchronous
decentralized federated averaging. A naive direct implementation shows degradation
in performance, arising from scheduling overheads and concurrent write conflicts
on GPUs. To mitigate these drawbacks, we investigate and propose a new method,
based on careful block selection rules, which update only portions of the parameter
vectors. Our experiments show that the resulting decentralized training method
exhibits improved throughput and competitive accuracy for standard image classification
benchmarks on the CIFAR-10, CIFAR-100, and Imagenet datasets. On the theoretical
side, we prove that our method guarantees sublinear ergodic convergence rates
for non-convex objectives.

text: Recent advancements on DAG-based consensus protocols allow for blockchains
with improved metrics and properties, such as throughput and censorship-resistance.
Variants of the Bullshark [18] consensus protocol are adopted for practical use
by the Sui blockchain, for improved latency. However, the protocol is leader-based,
and is strongly affected by crashed leaders that can lead to various performance
issues, for example, decreased transaction throughput. In this paper, we propose
HammerHead, a DAG-based consensus protocol, that is inspired by Carousel [8] and
provides Leader-Utilization. Our proposal differs from Carousel, which is built
for a chained consensus protocol; in HammerHead chain quality is inherited by
the DAG. HammerHead needs to preserve safety and liveness, despite validators
committing leader vertices asynchronously. The key idea is to update leader schedules
dynamically, based on the validators' scores during the previous schedule. We
implement HammerHead and show a minor improvement in performance for cases without
faults. The major improvements in comparison to Bullshark appear in faulty settings.
Specifically, we show a drastic, 2x-latency improvement and up to 40% increased
throughput when crash faults occur (100 validators, 33 faults).

teams for valuable feedback broadly, and specifically to Laura Makdah for helping
implementing the early reputation score system for validators and Dmitry Perelman
for managing the overall implementation effort.

text: The individualization of chromosomes during early mitosis and their clustering
upon exit from cell division are two key transitions that ensure efficient segregation
of eukaryotic chromosomes. Both processes are regulated by the surfactant-like
protein Ki-67, but how Ki-67 achieves these diametric functions has remained unknown.
Here, we report that Ki-67 radically switches from a chromosome repellent to a
chromosome attractant during anaphase in human cells. We show that Ki-67 dephosphorylation
during mitotic exit and the simultaneous exposure of a conserved basic patch induce
the RNA-dependent formation of a liquid-like condensed phase on the chromosome
surface. Experiments and coarse-grained simulations support a model in which the
coalescence of chromosome surfaces, driven by co-condensation of Ki-67 and RNA,
promotes clustering of chromosomes. Our study reveals how the switch of Ki-67
from a surfactant to a liquid-like condensed phase can generate mechanical forces
during genome segregation that are required for re-establishing nuclear-cytoplasmic
compartmentalization after mitosis.

text: Conserved signaling cascades monitor protein-folding homeostasis to ensure
proper cellular function. One of the evolutionary conserved key players is IRE1,
which maintains endoplasmic reticulum (ER) homeostasis through the unfolded protein
response (UPR). Upon accumulation of misfolded proteins in the ER, IRE1 forms
clusters on the ER membrane to initiate UPR signaling. What regulates IRE1 cluster
formation is not fully understood. Here, we show that the ER lumenal domain (LD)
of human IRE1α forms biomolecular condensates in vitro. IRE1α LD condensates were
stabilized both by binding to unfolded polypeptides as well as by tethering to
model membranes, suggesting their role in assembling IRE1α into signaling-competent
stable clusters. Molecular dynamics simulations indicated that weak multivalent
interactions drive IRE1α LD clustering. Mutagenesis experiments identified disordered
regions in IRE1α LD to control its clustering in vitro and in cells. Importantly,
dysregulated clustering of IRE1α mutants led to defects in IRE1α signaling. Our
results revealed that disordered regions in IRE1α LD control its clustering and
suggest their role as a common strategy in regulating protein assembly on membranes.

text: "The new era of Ge has opened up new possibilities in quantum computing. The
maturity of Ge\r\nspin qubits is unquestioned, while hybrid semiconductor-superconductor
Ge circuits are on track\r\nto enter the game. Gate-tunable transmons (gatemons)
employing semiconductor Josephson\r\njunctions have recently emerged as building
blocks for such hybrid quantum circuits. In this\r\nthesis, we present a gatemon
fabricated in planar Germanium. We induce superconductivity\r\nin a two-dimensional
hole gas by evaporating aluminum atop a thin spacer, which separates\r\nthe superconductor
from the Ge quantum well. The Josephson junction is then integrated\r\ninto an
Xmon circuit and capacitively coupled to a transmission line resonator. We showcase\r\nthe
qubit tunability in a broad frequency range with resonator and two-tone spectroscopy.\r\nTime-domain
characterizations reveal energy relaxation and coherence times up to 75 ns. Our\r\nresults,
combined with the recent advances in the spin qubit field, pave the way towards
novel\r\nhybrid and protected qubits in a group IV, CMOS-compatible material."

text: "Abstract. Continuous group key agreement (CGKA) allows a group of\r\nusers
to maintain a continuously updated shared key in an asynchronous\r\nsetting where
parties only come online sporadically and their messages\r\nare relayed by an
untrusted server. CGKA captures the basic primitive\r\nunderlying group messaging
schemes.\r\nCurrent solutions including TreeKEM (“Messaging Layer Security”\r\n(MLS)
IETF RFC 9420) cannot handle concurrent requests while retaining low communication
complexity. The exception being CoCoA, which\r\nis concurrent while having extremely
low communication complexity (in\r\ngroups of size n and for m concurrent updates
the communication per\r\nuser is log(n), i.e., independent of m). The main downside
of CoCoA\r\nis that in groups of size n, users might have to do up to log(n) update\r\nrequests
to the server to ensure their (potentially corrupted) key material has been refreshed.\r\nIn
this work we present a “fast healing” concurrent CGKA protocol,\r\nnamed DeCAF,
where users will heal after at most log(t) requests, with\r\nt being the number
of corrupted users. While also suitable for the standard central-server setting,
our protocol is particularly interesting for\r\nrealizing decentralized group
messaging, where protocol messages (add,\r\nremove, update) are being posted on
some append-only data structure\r\nrather than sent to a server. In this setting,
concurrency is crucial once\r\nthe rate of requests exceeds, say, the rate at
which new blocks are added\r\nto a blockchain.\r\nIn the central-server setting,
CoCoA (the only alternative with concurrency, sub-linear communication and basic
post-compromise security)\r\nenjoys much lower download communication. However,
in the decentralized setting – where there is no server which can craft specific
messages\r\nfor different users to reduce their download communication – our protocol\r\nsignificantly
outperforms CoCoA. DeCAF heals in fewer epochs (log(t)\r\nvs. log(n)) while incurring
a similar per epoch per user communication\r\ncost."

text: We present a theory describing the interaction of structured light, such as
light carrying orbital angular momentum, with molecules. The light-matter interaction
Hamiltonian we derive is expressed through couplings between spherical gradients
of the electric field and the (transition) electric multipole moments of a particle
of any nontrivial rotation point group. Our model can therefore accommodate an
arbitrary complexity of the molecular and electric field structure, and it can
be straightforwardly extended to atoms or nanostructures. Applying this framework
to rovibrational spectroscopy of molecules, we uncover the general mechanism of
angular momentum exchange between the spin and orbital angular momenta of light,
molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity
of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions
that are considered forbidden in the case of nonhelical light. We discuss the
experimental requirements for the observation of these forbidden transitions in
state-of-the-art spatially resolved spectroscopy measurements.

text: "Instant messaging applications like Whatsapp, Signal or Telegram have become
ubiquitous in today's society.\r\nMany of them provide not only end-to-end encryption,
but also security guarantees even when the key material gets compromised.\r\nThese
are achieved through frequent key update performed by users.\r\nIn particular,
the compromise of a group key should preserve confidentiality of previously exchanged
messages (forward secrecy), and a subsequent key update will ensure security for
future ones (post-compromise security).\r\nThough great protocols for one-on-one
communication have been known for some time, the design of ones that scale efficiently
for larger groups while achieving akin security guarantees is a hard problem.\r\nA
great deal of research has been aimed at this topic, much of it under the umbrella
of the Messaging Layer Security (MLS) working group at the IETF. \r\nStarted in
2018, this joint effort by academics and industry culminated in 2023 with the
publication of the first standard for secure group messaging [IETF, RFC9420].\r\n\r\nAt
the core of secure group messaging is a cryptographic primitive termed Continuous
Group Key Agreement, or CGKA [Alwen et al. 2021], that essentially allows a changing
group of users to agree on a common key with the added functionality security
against compromises is achieved by users asynchronously issuing a key update.
In this thesis we contribute to the understanding of CGKA across different angles.\r\nFirst,
we present a new technique to effect dynamic operations in groups, i.e., add or
remove members, that can be more efficient that the one employed by MLS in certain
settings.\r\nConsidering the setting of users belonging to multiple overlapping
groups, we then show lowerbounds on the communication cost of constructions that
leverage said overlap, at the same time showing protocols that are asymptotically
optimal and efficient for practical settings, respectively. Along the way, we
show that the communication cost of key updates in MLS is average-cost optimal.\r\nAn
important feature in CGKA protocols, particularly for big groups, is the possibility
of executing several group operations concurrently. While later versions of MLS
support this, they do at the cost of worsening the communication efficiency of
future group operations.\r\nIn this thesis we introduce two new protocols that
permit concurrency without any negative effect on efficiency. Our protocols circumvent
previously existing lower bounds by satisfying a new notion of post-compromise
security that only asks for security to be re-established after a certain number
of key updates have taken place. While this can be slower than MLS in terms of
rounds of communication, we show that it leads to more efficient overall communication.
\r\nAdditionally, we introduce a new technique that allows group members to decrease
the information they need to store and download, which makes one of our protocols
enjoy much lower download cost than any other existing CGKA constructions. "

text: "In our companion paper \"Tight bounds for the learning of homotopy à la Niyogi,
Smale, and Weinberger for subsets of Euclidean spaces and of Riemannian manifolds\"
we gave optimal bounds (in terms of the two one-sided Hausdorff distances) on
a sample P of an input shape \U0001D4AE (either manifold or general set with positive
reach) such that one can infer the homotopy of \U0001D4AE from the union of balls
with some radius centred at P, both in Euclidean space and in a Riemannian manifold
of bounded curvature. The construction showing the optimality of the bounds is
not straightforward. The purpose of this video is to visualize and thus elucidate
said construction in the Euclidean setting."

text: We consider a dilute fully spin-polarized Fermi gas at positive temperature
in dimensions d∈{1,2,3} . We show that the pressure of the interacting gas is
bounded from below by that of the free gas plus, to leading order, an explicit
term of order adρ2+2/d, where a is the p-wave scattering length of the repulsive
interaction and ρ is the particle density. The results are valid for a wide
range of repulsive interactions, including that of a hard core, and uniform in
temperatures at most of the order of the Fermi temperature. A central ingredient
in the proof is a rigorous implementation of the fermionic cluster expansion of
Gaudin, Gillespie and Ripka (Nucl. Phys. A, 176.2 (1971), pp. 237–260).
