text: We perform a diagrammatic analysis of the energy of a mobile impurity immersed
in a strongly interacting two-component Fermi gas to second order in the impurity-bath
interaction. These corrections demonstrate divergent behavior in the limit of
large impurity momentum. We show the fundamental processes responsible for these
logarithmically divergent terms. We study the problem in the general case without
any assumptions regarding the fermion-fermion interactions in the bath. We show
that the divergent term can be summed up to all orders in the Fermi-Fermi interaction
and that the resulting expression is equivalent to the one obtained in the few-body
calculation. Finally, we provide a perturbative calculation to the second order
in the Fermi-Fermi interaction, and we show the diagrams responsible for these
terms.

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.

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 fungal bioluminescence pathway can be reconstituted in other organisms
allowing luminescence imaging without exogenously supplied substrate. The pathway
starts from hispidin biosynthesis—a step catalyzed by a large fungal polyketide
synthase that requires a posttranslational modification for activity. Here, we
report identification of alternative compact hispidin synthases encoded by a phylogenetically
diverse group of plants. A hybrid bioluminescence pathway that combines plant
and fungal genes is more compact, not dependent on availability of machinery for
posttranslational modifications, and confers autonomous bioluminescence in yeast,
mammalian, and plant hosts. The compact size of plant hispidin synthases enables
additional modes of delivery of autoluminescence, such as delivery with viral
vectors.

text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.

text: We demonstrate the failure of the adiabatic Born-Oppenheimer approximation
to describe the ground state of a quantum impurity within an ultracold Fermi gas
despite substantial mass differences between the bath and impurity species. Increasing
repulsion leads to the appearance of nonadiabatic couplings between the fast bath
and slow impurity degrees of freedom, which reduce the parity symmetry of the
latter according to the pseudo Jahn-Teller effect. The presence of this mechanism
is associated to a conical intersection involving the impurity position and the
inverse of the interaction strength, which acts as a synthetic dimension. We elucidate
the presence of these effects via a detailed ground-state analysis involving the
comparison of ab initio fully correlated simulations with effective models. Our
study suggests ultracold atomic ensembles as potent emulators of complex molecular
phenomena.

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
positive phases (a joint positive phase). For the monsoons, which are exceptions
in this regard, we found northeast India often gets excess pre-monsoon rainfall.
Further investigation reveals that this excess pre-monsoon rainfall is produced
by the interaction of the large-scale circulation associated with the joint phase
with the mountains in northeast India. We posit that a warmer troposphere, a consequence
of excess rainfall over northeast India, drives a stronger monsoon circulation
and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
rainfall over northeast India can be used for seasonal monsoon rainfall prediction
over central India. Most importantly, its predictive value is at its peak when
the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
monsoon looms over India.

text: The extracellular matrix (ECM) serves as a scaffold for cells and plays an
essential role in regulating numerous cellular processes, including cell migration
and proliferation. Due to limitations in specimen preparation for conventional
room-temperature electron microscopy, we lack structural knowledge on how ECM
components are secreted, remodeled, and interact with surrounding cells. We have
developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion
beam milling, the lift-out extraction procedure, and cryo-electron tomography.
Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting
in a versatile tool closely mimicking ECM environments. This allows us to visualize
ECM for the first time in its hydrated, native context. Our data reveal an intricate
network of extracellular fibers, their positioning relative to matrix-secreting
cells, and previously unresolved structural entities. Our workflow and results
add to the structural atlas of the ECM, providing novel insights into its secretion
and assembly.

text: We prove an upper bound on the ground state energy of the dilute spin-polarized
Fermi gas capturing the leading correction to the kinetic energy resulting from
repulsive interactions. One of the main ingredients in the proof is a rigorous
implementation of the fermionic cluster expansion of Gaudin et al. (1971) [15].

text: The mammary gland consists of a bilayered epithelial structure with an extensively
branched morphology. The majority of this epithelial tree is laid down during
puberty, during which actively proliferating terminal end buds repeatedly elongate
and bifurcate to form the basic structure of the ductal tree. Mammary ducts consist
of a basal and luminal cell layer with a multitude of identified sub-lineages
within both layers. The understanding of how these different cell lineages are
cooperatively driving branching morphogenesis is a problem of crossing multiple
scales, as this requires information on the macroscopic branched structure of
the gland, as well as data on single-cell dynamics driving the morphogenic program.
Here we describe a method to combine genetic lineage tracing with whole-gland
branching analysis. Quantitative data on the global organ structure can be used
to derive a model for mammary gland branching morphogenesis and provide a backbone
on which the dynamics of individual cell lineages can be simulated and compared
to lineage-tracing approaches. Eventually, these quantitative models and experiments
allow to understand the couplings between the macroscopic shape of the mammary
gland and the underlying single-cell dynamics driving branching morphogenesis.

text: Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling
(SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose
and interpret quantum simulators of this problem in cold Bose gases. First, we
derive a master equation that describes the model and explore it in a one-dimensional
(1D) setting. To validate the standard assumptions needed for our derivation,
we analyze available experimental data without SOC; as a byproduct, this analysis
suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron
approach at temperatures currently accessible in a cold-atom laboratory—motion
of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate
that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the
information about SOC is incorporated in the initial conditions. Observables sensitive
to this information (such as spin densities) can be used to study formation of
steady spin polarization domains during quench dynamics.

text: 'Post-translational histone modifications modulate chromatin activity to affect
gene expression. How chromatin states underlie lineage choice in single cells
is relatively unexplored. We develop sort-assisted single-cell chromatin immunocleavage
(sortChIC) and map active (H3K4me1 and H3K4me3) and repressive (H3K27me3 and H3K9me3)
histone modifications in the mouse bone marrow. During differentiation, hematopoietic
stem and progenitor cells (HSPCs) acquire active chromatin states mediated by
cell-type-specifying transcription factors, which are unique for each lineage.
By contrast, most alterations in repressive marks during differentiation occur
independent of the final cell type. Chromatin trajectory analysis shows that lineage
choice at the chromatin level occurs at the progenitor stage. Joint profiling
of H3K4me1 and H3K9me3 demonstrates that cell types within the myeloid lineage
have distinct active chromatin but share similar myeloid-specific heterochromatin
states. This implies a hierarchical regulation of chromatin during hematopoiesis:
heterochromatin dynamics distinguish differentiation trajectories and lineages,
while euchromatin dynamics reflect cell types within lineages.'

text: Turn-based stochastic games (aka simple stochastic games) are two-player zero-sum
games played on directed graphs with probabilistic transitions. The goal of player-max
is to maximize the probability to reach a target state against the adversarial
player-min. These games lie in NP ∩ coNP and are among the rare combinatorial
problems that belong to this complexity class for which the existence of polynomial-time
algorithm is a major open question. While randomized sub-exponential time algorithm
exists, all known deterministic algorithms require exponential time in the worst-case.
An important open question has been whether faster algorithms can be obtained
parametrized by the treewidth of the game graph. Even deterministic sub-exponential
time algorithm for constant treewidth turn-based stochastic games has remain elusive.
In this work our main result is a deterministic algorithm to solve turn-based
stochastic games that, given a game with n states, treewidth at most t, and the
bit-complexity of the probabilistic transition function log D, has running time
O ((tn2 log D)t log n). In particular, our algorithm is quasi-polynomial time
for games with constant or poly-logarithmic treewidth.

text: Here we describe the in vivo DNA assembly approach, where molecular cloning
procedures are performed using an E. coli recA-independent recombination pathway,
which assembles linear fragments of DNA with short homologous termini. This pathway
is present in all standard laboratory E. coli strains and, by bypassing the need
for in vitro DNA assembly, allows simplified molecular cloning to be performed
without the plasmid instability issues associated with specialized recombination-cloning
bacterial strains. The methodology requires specific primer design and can perform
all standard plasmid modifications (insertions, deletions, mutagenesis, and sub-cloning)
in a rapid, simple, and cost-efficient manner, as it does not require commercial
kits or specialized bacterial strains. Additionally, this approach can be used
to perform complex procedures such as multiple modifications to a plasmid, as
up to 6 linear fragments can be assembled in vivo by this recombination pathway.
Procedures generally require less than 3 h, involving PCR amplification, DpnI
digestion of template DNA, and transformation, upon which circular plasmids are
assembled. In this chapter we describe the requirements, procedure, and potential
pitfalls when using this technique, as well as protocol variations to overcome
the most common issues.

text: "Asynchronous programming has gained significant popularity over the last
decade: support for this programming pattern is available in many popular languages
via libraries and native language implementations, typically in the form of coroutines
or the async/await construct. Instead of programming via shared memory, this concept
assumes implicit synchronization through message passing. The key data structure
enabling such communication is the rendezvous channel. Roughly, a rendezvous channel
is a blocking queue of size zero, so both send(e) and receive() operations wait
for each other, performing a rendezvous when they meet. To optimize the message
passing pattern, channels are usually equipped with a fixed-size buffer, so sends
do not suspend and put elements into the buffer until its capacity is exceeded.
This primitive is known as a buffered channel.\r\n\r\nThis paper presents a fast
and scalable algorithm for both rendezvous and buffered channels. Similarly to
modern queues, our solution is based on an infinite array with two positional
counters for send(e) and receive() operations, leveraging the unconditional Fetch-And-Add
instruction to update them. Yet, the algorithm requires non-trivial modifications
of this classic pattern, in order to support the full channel semantics, such
as buffering and cancellation of waiting requests. We compare the performance
of our solution to that of the Kotlin implementation, as well as against other
academic proposals, showing up to 9.8× speedup. To showcase its expressiveness
and performance, we also integrated the proposed algorithm into the standard Kotlin
Coroutines library, replacing the previous channel implementations."

text: Although a wide variety of handcrafted concurrent data structures have been
proposed, there is considerable interest in universal approaches (Universal Constructions
or UCs) for building concurrent data structures. UCs (semi-)automatically convert
a sequential data structure into a concurrent one. The simplest approach uses
locks [3, 6] that protect a sequential data structure and allow only one process
to access it at a time. However, the resulting data structure is blocking. Most
work on UCs instead focuses on obtaining non-blocking progress guarantees such
as obstruction-freedom, lock-freedom or wait-freedom. Many non-blocking UCs have
appeared. Key examples include the seminal wait-free UC [2] by Herlihy, a NUMA-aware
UC [10] by Yi et al., and an efficient UC for large objects [1] by Fatourou et
al.

text: "Dynamic programming (DP) is one of the fundamental paradigms in algorithm
design. However,\r\nmany DP algorithms have to fill in large DP tables, represented
by two-dimensional arrays, which causes at least quadratic running times and space
usages. This has led to the development of improved algorithms for special cases
when the DPs satisfy additional properties like, e.g., the Monge property or total
monotonicity.\r\nIn this paper, we consider a new condition which assumes (among
some other technical assumptions) that the rows of the DP table are monotone.
Under this assumption, we introduce\r\na novel data structure for computing (1
+ ϵ)-approximate DP solutions in near-linear time and\r\nspace in the static setting,
and with polylogarithmic update times when the DP entries change\r\ndynamically.
To the best of our knowledge, our new condition is incomparable to previous conditions
and is the first which allows to derive dynamic algorithms based on existing DPs.
Instead of using two-dimensional arrays to store the DP tables, we store the rows
of the DP tables using monotone piecewise constant functions. This allows us to
store length-n DP table rows with entries in [0, W] using only polylog(n, W) bits,
and to perform operations, such as (min, +)-convolution or rounding, on these
functions in polylogarithmic time.\r\nWe further present several applications
of our data structure. For bicriteria versions of k-balanced graph partitioning
and simultaneous source location, we obtain the first dynamic algorithms with
subpolynomial update times, as well as the first static algorithms using only
near-linear time and space. Additionally, we obtain the currently fastest algorithm
for fully dynamic knapsack."

text: "The process of detecting and evaluating sensory information to guide behaviour
is termed perceptual decision-making (PDM), and is critical for the ability of
an organism to interact with its external world. Individuals with autism, a neurodevelopmental
condition primarily characterised by social and communication difficulties, frequently
exhibit altered sensory processing and PDM difficulties are widely reported. Recent
technological advancements have pushed forward our understanding of the genetic
changes accompanying this condition, however our understanding of how these mutations
affect the function of specific neuronal circuits and bring about the corresponding
behavioural changes remains limited. Here, we use an innate PDM task, the looming
avoidance response (LAR) paradigm, to identify a convergent behavioural abnormality
across three molecularly distinct genetic mouse models of autism (Cul3, Setd5
and Ptchd1). Although mutant mice can rapidly detect threatening visual stimuli,
their responses are consistently delayed, requiring longer to initiate an appropriate
response than their wild-type siblings. Mutant animals show abnormal adaptation
in both their stimulus- evoked escape responses and exploratory dynamics following
repeated stimulus presentations. Similarly delayed behavioural responses are observed
in wild-type animals when faced with more ambiguous threats, suggesting the mutant
phenotype could arise from a dysfunction in the flexible control of this PDM process.\r\nOur
knowledge of the core neuronal circuitry mediating the LAR facilitated a detailed
dissection of the neuronal mechanisms underlying the behavioural impairment. In
vivo extracellular recording revealed that visual responses were unaffected within
a key brain region for the rapid processing of visual threats, the superior colliculus
(SC), indicating that the behavioural delay was unlikely to originate from sensory
impairments. Delayed behavioural responses were recapitulated in the Setd5 model
following optogenetic stimulation of the excitatory output neurons of the SC,
which are known to mediate escape initiation through the activation of cells in
the underlying dorsal periaqueductal grey (dPAG). In vitro patch-clamp recordings
of dPAG cells uncovered a stark hypoexcitability phenotype in two out of the three
genetic models investigated (Setd5 and Ptchd1), that in Setd5, is mediated by
the misregulation of voltage-gated potassium channels. Overall, our results show
that the ability to use visual information to drive efficient escape responses
is impaired in three diverse genetic mouse models of autism and that, in one of
the models studied, this behavioural delay likely originates from differences
in the intrinsic excitability of a key subcortical node, the dPAG. Furthermore,
this work showcases the use of an innate behavioural paradigm to mechanistically
dissect PDM processes in autism."
