text: We used diverse methods to characterize the role of avian lateral spiriform
nucleus (SpL) in basal ganglia motor function. Connectivity analysis showed that
SpL receives input from globus pallidus (GP), and the intrapeduncular nucleus
(INP) located ventromedial to GP, whose neurons express numerous striatal markers.
SpL-projecting GP neurons were large and aspiny, while SpL-projecting INP neurons
were medium sized and spiny. Connectivity analysis further showed that SpL receives
inputs from subthalamic nucleus (STN) and substantia nigra pars reticulata (SNr),
and that the SNr also receives inputs from GP, INP, and STN. Neurochemical analysis
showed that SpL neurons express ENK, GAD, and a variety of pallidal neuron markers,
and receive GABAergic terminals, some of which also contain DARPP32, consistent
with GP pallidal and INP striatal inputs. Connectivity and neurochemical analysis
showed that the SpL input to tectum prominently ends on GABAA receptor-enriched
tectobulbar neurons. Behavioral studies showed that lesions of SpL impair visuomotor
behaviors involving tracking and pecking moving targets. Our results suggest that
SpL modulates brainstem-projecting tectobulbar neurons in a manner comparable
to the demonstrated influence of GP internus on motor thalamus and of SNr on tectobulbar
neurons in mammals. Given published data in amphibians and reptiles, it seems
likely the SpL circuit represents a major direct pathway-type circuit by which
the basal ganglia exerts its motor influence in nonmammalian tetrapods. The present
studies also show that avian striatum is divided into three spatially segregated
territories with differing connectivity, a medial striato-nigral territory, a
dorsolateral striato-GP territory, and the ventrolateral INP motor territory.

text: We report JWST/NIRCam measurements of quasar host galaxy emissions and supermassive
black hole (SMBH) masses for six quasars at 5.9 < z < 7.1 in the Emission-line
galaxies and Intergalactic Gas in the Epoch of Reionization (EIGER) project. We
obtain deep NIRCam imaging in the F115W, F200W, and F356W bands, as well as F356W
grism spectroscopy of the quasars. We use bright unsaturated stars to construct
models of the point-spread functions (PSFs) and estimate the errors of these PSFs.
We then measure or constrain the fluxes and morphology of the quasar host galaxies
by fitting the quasar images as a point source plus an exponential disk. We successfully
detect the host galaxies of three quasars, which have host-to-quasar-flux ratios
of ∼1%–5%. Spectral energy distribution fitting suggests that these quasar host
galaxies have stellar masses of M* ≳ 1010M⊙. For quasars with host galaxy nondetections,
we estimate the upper limits of their stellar masses. We use the grism spectra
to measure the Hβ line profile and the continuum luminosity, then estimate the
SMBH masses for the quasars. Our results indicate that the positive relation between
SMBH masses and host galaxy stellar masses already exists at redshift z ≳ 6. The
quasars in our sample show a high BH-to-stellar-mass ratio of MBH/M* ∼ 0.15, which
is about ∼2 dex higher than local relations. We find that selection effects only
contribute partially to the high MBH/M* ratios of high-redshift quasars. This
result hints at a possible redshift evolution of the MBH–M* relation.

text: 'We report on dynamic Shubnikov–de Haas (SdH) oscillations that are measured
in the optical response, subterahertz transmittance of two-dimensional systems,
and reveal two distinct types of oscillation nodes: “universal” nodes at integer
ratios of radiation and cyclotron frequencies and “tunable” nodes at positions
sensitive to all parameters of the structure. The nodes in both real and imaginary
parts of the measured complex transmittance are analyzed using a dynamic version
of the static Lifshitz-Kosevich formula. These results demonstrate that the node
structure of the dynamic SdH oscillations provides an all-optical access to quantization-
and interaction-induced renormalization effects, in addition to parameters one
can obtain from the static SdH oscillations.'

text: We propose and implement a family of quantum-informed recursive optimization
(QIRO) algorithms for combinatorial optimization problems. Our approach leverages
quantum resources to obtain information that is used in problem-specific classical
reduction steps that recursively simplify the problem. These reduction steps address
the limitations of the quantum component (e.g., locality) and ensure solution
feasibility in constrained optimization problems. Additionally, we use backtracking
techniques to further improve the performance of the algorithm without increasing
the requirements on the quantum hardware. We showcase the capabilities of our
approach by informing QIRO with correlations from classical simulations of shallow
circuits of the quantum approximate optimization algorithm, solving instances
of maximum independent set and maximum satisfiability problems with hundreds of
variables. We also demonstrate how QIRO can be deployed on a neutral atom quantum
processor to find large independent sets of graphs. In summary, our scheme achieves
results comparable to classical heuristics even with relatively weak quantum resources.
Furthermore, enhancing the quality of these quantum resources improves the performance
of the algorithms. Notably, the modular nature of QIRO offers various avenues
for modifications, positioning our work as a template for a broader class of hybrid
quantum-classical algorithms for combinatorial optimization.

text: "Background: IgE-mediated degranulation of mast cells (MCs) provides rapid
protection against environmental hazards, including animal venoms. A fraction
of tissue-resident MCs intimately associates with blood vessels. These perivascular
MCs were reported to extend projections into the vessel lumen and to be the first
MCs to acquire intravenously injected IgE, suggesting that IgE loading of MCs
depends on their vascular association.\r\nObjective: We sought to elucidate the
molecular basis of the MC–blood vessel interaction and to determine its relevance
for IgE-mediated immune responses.\r\nMethods: We selectively inactivated the
Itgb1 gene, encoding the β1 chain of integrin adhesion molecules (ITGB1), in MCs
by conditional gene targeting in mice. We analyzed skin MCs for blood vessel association,
surface IgE density, and capability to bind circulating antibody specific for
MC surface molecules, as well as in vivo responses to antigen administered via
different routes.\r\nResults: Lack of ITGB1 expression severely compromised MC–blood
vessel association. ITGB1-deficient MCs showed normal densities of surface IgE
but reduced binding of intravenously injected antibodies. While their capacity
to degranulate in response to IgE ligation in vivo was unimpaired, anaphylactic
responses to antigen circulating in the vasculature were largely abolished.\r\nConclusions:
ITGB1-mediated association of MCs with blood vessels is key for MC immune surveillance
of blood vessel content, but is dispensable for slow steady-state loading of endogenous
IgE onto tissue-resident MCs."

text: 'Bacterial cell walls are gigadalton-large cross-linked polymers with a wide
range of motional amplitudes, including rather rigid as well as highly flexible
parts. Magic-angle spinning NMR is a powerful method to obtain atomic-level information
about intact cell walls. Here we investigate sensitivity and information content
of different homonuclear 13C-13C and heteronuclear H-N, H-C and N-C correlation
experiments. We demonstrate that a CPMAS CryoProbe yields ca. 8-fold increased
signal-to-noise over a room-temperature probe, or a ca. 3-4-fold larger per-mass
sensitivity. The increased sensitivity allowed to obtain high-resolution spectra
even on intact bacteria. Moreover, we compare resolution and sensitivity of 1H
MAS experiments obtained at 100 kHz vs. 55 kHz. Our study provides useful hints
for choosing experiments to extract atomic-level details on cell-wall samples. '

text: We provide a dynamical study of a model of multiplicative perturbation of
a unitary matrix introduced by Fyodorov. In particular, we identify a flow of
deterministic domains that bound the spectrum with high probability, separating
the outlier from the typical eigenvalues at all sub-critical timescales. These
results are obtained under generic assumptions on U that hold for a variety of
unitary random matrix models.

text: A key mechanism employed by plants to adapt to salinity stress involves maintaining
ion homeostasis via the actions of ion transporters. While the function of cation
transporters in maintaining ion homeostasis in plants has been extensively studied,
little is known about the roles of their anion counterparts in this process. Here,
we describe a mechanism of salt adaptation in plants. We characterized the chloride
channel (CLC) gene AtCLCf, whose expression is regulated by WRKY transcription
factor under salt stress in Arabidopsis thaliana. Loss-of-function atclcf seedlings
show increased sensitivity to salt, whereas AtCLCf overexpression confers enhanced
resistance to salt stress. Salt stress induces the translocation of GFP-AtCLCf
fusion protein to the plasma membrane (PM). Blocking AtCLCf translocation using
the exocytosis inhibitor brefeldin-A or mutating the small GTPase gene AtRABA1b/BEX5
(RAS GENES FROM RAT BRAINA1b homolog) increases salt sensitivity in plants. Electrophysiology
and liposome-based assays confirm the Cl−/H+ antiport function of AtCLCf. Therefore,
we have uncovered a mechanism of plant adaptation to salt stress involving the
NaCl-induced translocation of AtCLCf to the PM, thus facilitating Cl− removal
at the roots, and increasing the plant’s salinity tolerance.

text: The process of polymer condensation, i.e., the formation of bonds between
reactive end groups, is ubiquitous in both industry and biology. Here we study
generic systems undergoing polymer condensation in competition with cyclization.
Using a generalized Smoluchowski theory, molecular dynamics simulations and experiments
with DNA and ATP-consuming T4 ligase, we find that this system displays a transition,
from a ring-dominated regime with finite-length chains at infinite time to a linear-polymers-dominated
one with chains that keep growing in time. Finally, we show that fluids prepared
close to the transition may have widely different compositions and rheology at
large condensation times.

text: "Memory-hard functions (MHF) are functions whose evaluation provably requires\r\na
lot of memory. While MHFs are an unkeyed primitive, it is natural to consider
the\r\nnotion of trapdoor MHFs (TMHFs). A TMHF is like an MHF, but when sampling\r\nthe
public parameters one also samples a trapdoor which allows evaluating the\r\nfunction
much cheaper.\r\nBiryukov and Perrin (Asiacrypt’17) were the first to consider
TMHFs and put\r\nforth a candidate TMHF construction called Diodon that is based
on the Scrypt\r\nMHF (Percival, BSDCan’09). To allow for a trapdoor, Scrypt’s
initial hash chain\r\nis replaced by a sequence of squares in a group of unknown
order where the order of\r\nthe group is the trapdoor. For a length n sequence
of squares and a group of order\r\nN, Diodon’s cumulative memory complexity (CMC)
is O(n2log N) without the\r\ntrapdoor and O(n log(n) log(N)2) with knowledge of
it.\r\nWhile Scrypt is proven to be optimally memory-hard in the random oracle\r\nmodel
(Alwen et al., Eurocrypt’17), Diodon’s memory-hardness has not been\r\nproven
so far. In this work, we fill this gap by rigorously analyzing a specific\r\ninstantiation
of Diodon. We show that its CMC is lower bounded by Ω( n2log nlog N)\r\nwhich
almost matches the upper bound. Our proof is based Alwen et al.’s lower\r\nbound
on Scrypt’s CMC but requires non-trivial modifications due to the algebraic\r\nstructure
of Diodon. Most importantly, our analysis involves a more elaborate\r\ncompression
argument and a solvability criterion for certain systems of Diophantine\r\nequations."

text: Photoisomerization and photoluminescence are two distinct energy dissipation
pathways in light-driven molecular motors. The photoisomerization properties of
discrete molecular motors have been well established in solution, but their photoluminescent
properties have been rarely reported—especially in aggregates. Here, it is shown
that an overcrowded alkene-based molecular motor exhibits distinct dynamic properties
in solution and aggregate states, for example, gel and solid states. Despite the
poor emissive properties of molecular motors in solution, a bright emission is
observed in the aggregate states, including in gel and the crystalline solid.
The emission wavelength is highly dependent on the nature of the supramolecular
packing and order in the aggregates. As a result, the fluorescent color can be
readily tuned reversibly via mechanical grinding and vapor fuming, which provides
a new platform for developing multi-stimuli functional materials.

text: How the coordination of neuronal spiking and brain rhythms between hippocampal
subregions supports memory function remains elusive. We studied the interregional
coordination of CA3 neuronal spiking with CA1 theta oscillations by recording
electrophysiological signals along the proximodistal axis of the hippocampus in
rats that were performing a high-memory-demand recognition memory task adapted
from humans. We found that CA3 population spiking occurs preferentially at the
peak of distal CA1 theta oscillations when memory was tested but only when previously
encountered stimuli were presented. In addition, decoding analyses revealed that
only population cell firing of proximal CA3 together with that of distal CA1 can
predict performance at test in the present non-spatial task. Overall, our work
demonstrates an important role for the synchronization of CA3 neuronal activity
with CA1 theta oscillations during memory testing.

text: Primordial neutral atomic gas, mostly composed of hydrogen, is the raw material
for star formation in galaxies. However, there are few direct constraints on the
amount of neutral atomic hydrogen (H i) in galaxies at early cosmic times. We
analyzed James Webb Space Telescope (JWST) near-infrared spectroscopy of distant
galaxies, at redshifts ≳8. From a sample of 12 galaxies, we identified three that
show strong damped Lyman-α absorption due to H i in their local surroundings.
The galaxies are located at spectroscopic redshifts of 8.8, 10.2, and 11.4, corresponding
to 400 to 600 million years after the Big Bang. They have H i column densities
≳1022 cm−2, which is an order of magnitude higher than expected for a fully neutral
intergalactic medium, and constitute a gas-rich population of young star-forming
galaxies.

text: Memories are thought to be stored in neural ensembles known as engrams that
are specifically reactivated during memory recall. Recent studies have found that
memory engrams of two events that happened close in time tend to overlap in the
hippocampus and the amygdala, and these overlaps have been shown to support memory
linking. It has been hypothesized that engram overlaps arise from the mechanisms
that regulate memory allocation itself, involving neural excitability, but the
exact process remains unclear. Indeed, most theoretical studies focus on synaptic
plasticity and little is known about the role of intrinsic plasticity, which could
be mediated by neural excitability and serve as a complementary mechanism for
forming memory engrams. Here, we developed a rate-based recurrent neural network
that includes both synaptic plasticity and neural excitability. We obtained structural
and functional overlap of memory engrams for contexts that are presented close
in time, consistent with experimental and computational studies. We then investigated
the role of excitability in memory allocation at the network level and unveiled
competitive mechanisms driven by inhibition. This work suggests mechanisms underlying
the role of intrinsic excitability in memory allocation and linking, and yields
predictions regarding the formation and the overlap of memory engrams.

(asynchrony), but also 3) constraints in the amount of communication between the
clients and the server. In this work, we present the first variant of the classic
federated averaging (FedAvg) algorithm which, at the same time, supports data
heterogeneity, partial client asynchrony, and communication compression. Our algorithm
comes with a novel, rigorous analysis showing that, in spite of these system relaxations,
it can provide similar convergence to FedAvg in interesting parameter regimes.
Experimental results in the rigorous LEAF benchmark on setups of up to 300 nodes
show that our algorithm ensures fast convergence for standard federated tasks,
improving upon prior quantized and asynchronous approaches.'

text: Turn-based discounted-sum games are two-player zero-sum games played on finite
directed graphs. The vertices of the graph are partitioned between player 1 and
player 2. Plays are infinite walks on the graph where the next vertex is decided
by a player that owns the current vertex. Each edge is assigned an integer weight
and the payoff of a play is the discounted-sum of the weights of the play. The
goal of player 1 is to maximize the discounted-sum payoff against the adversarial
player 2. These games lie in NP ∩ coNP and are among the rare combinatorial problems
that belong to this complexity class and the existence of a polynomial-time algorithm
is a major open question. Since breaking the general exponential barrier has been
a challenging problem, faster parameterized algorithms have been considered. If
the discount factor is expressed in unary, then discounted-sum games can be solved
in polynomial time. However, if the discount factor is arbitrary (or expressed
in binary), but the weights are in unary, none of the existing approaches yield
a sub-exponential bound. Our main result is a new analysis technique for a classical
algorithm (namely, the strategy iteration algorithm) that present a new runtime
bound which is [EQUATION] for game graphs with n vertices and absolute weights
of at most W. In particular, our result yields a deterministic sub-exponential
bound for games with weights that are constant or represented in unary.

text: "We study two-player zero-sum concurrent stochastic games with finite state
and action space played for an infinite number of steps. In every step, the two
players simultaneously and independently choose an action. Given the current state
and the chosen actions, the next state is obtained according to a stochastic transition
function. An objective is a measurable function on plays (or infinite trajectories)
of the game, and the value for an objective is the maximal expectation that the
player can guarantee against the adversarial player. We consider: (a) stateful-discounted
objectives, which are similar to the classical discounted-sum objectives, but
states are associated with different discount factors rather than a single discount
factor; and (b) parity objectives, which are a canonical representation for ω-regular
objectives. For stateful-discounted objectives, given an ordering of the discount
factors, the limit value is the limit of the value of the stateful-discounted
objectives, as the discount factors approach zero according to the given order.\r\nThe
computational problem we consider is the approximation of the value within an
arbitrary\r\nadditive error. The above problem is known to be in EXPSPACE for
the limit value of statefuldiscounted objectives and in PSPACE for parity objectives.
The best-known algorithms for both the above problems are at least exponential
time, with an exponential dependence on the number of states and actions. Our
main results for the value approximation problem for the limit value of stateful-discounted
objectives and parity objectives are as follows: (a) we establish TFNP[NP] complexity;
and (b) we present algorithms that improve the dependency on the number of actions
in the exponent from linear to logarithmic. In particular, if the number of states
is constant, our algorithms run in polynomial time."

text: "This paper considers a class of two-player zero-sum games on directed graphs
whose vertices are equipped with random payoffs of bounded support known by both
players.\r\nStarting from a fixed vertex, players take turns to move a token along
the edges of the graph.\r\nOn the one hand, for acyclic directed graphs of bounded
degree and sub-exponential expansion, we show that the value of the game converges
almost surely to a constant at an exponential rate dominated in terms of the expansion.\r\nOn
the other hand, for the infinite d-ary tree that does not fall into the previous
class of graphs, we show convergence at a double-exponential rate in terms of
the expansion."
