text: A floating Leidenfrost droplet exhibits curvature inversion of its underside,
due to the balance of vapor pressure and surface tension. Using interferometric
imaging, we find different behavior for a levitated hydrogel sphere. Curvature
inversion is observed briefly just after deposition, but quickly gives way to
a steady state with no inversion. We show the essential role of vaporization in
shaping the underbelly of the hydrogel, where changes due to direct mass loss
are more significant than the balance of vapor pressure and elastic forces.

text: 'Promoters and enhancers are cis-regulatory elements (CREs), DNA sequences
that bind transcription factor (TF) proteins to up- or down-regulate target genes.
Decades-long efforts yielded TF-DNA interaction models that predict how strongly
an individual TF binds arbitrary DNA sequences and how individual binding events
on the CRE combine to affect gene expression. These insights can be synthesized
into a global, biophysically realistic, and quantitative genotype–phenotype map
for gene regulation, a ‘holy grail’ for the application of evolutionary theory.
A global map provides a rare opportunity to simulate the long-term evolution of
regulatory sequences and pose several fundamental questions: How long does it
take to evolve CREs de novo? How many non-trivial regulatory functions exist in
sequence space? How connected are they? For which regulatory architecture is CRE
evolution most rapid and evolvable? In this article, the first of a two-part series,
we briefly review the pertinent modeling and simulation efforts for a unique system
that enables close, quantitative, and mechanistic links between biophysics, as
well as systems, synthetic, and evolutionary biology.'

text: Adaptive plant development is orchestrated, among others, by directional,
intercellular transport of the phytohormone auxin. Self-organizing development,
such as flexible vasculature formation, depends on so-called auxin canalization,
manifested by the gradual formation of auxin transport channels through feedback
between auxin signalling and transport. Herein, we identify MAKR6 as an important,
novel component in this feedback. MAKR6 expression accumulates strongly in vascular
cells and is tightly regulated by auxin via the Aux/IAA-ARF-WRKY23 transcriptional
network. MAKR6 is required for auxin canalization-dependent processes, including
leaf venation, vasculature regeneration, and de novo auxin channel formation from
local auxin sources. Mechanistically, MAKR6 interacts with the PIN1 auxin transporter,
modulating its trafficking and polarization. MAKR6 also associates with and integrates
two key receptor-like kinase complexes involved in canalization, TMK1/4 and the
CAMEL-CANAR. Together, our study establishes MAKR6 as a multifaceted regulator
that couples transcriptional auxin signalling to PIN1 repolarization and coordinates
multiple RLK-mediated signalling pathways during canalization. This provides mechanistic
insights into auxin canalization and exemplifies a framework for exploring similar
regulatory nodes in other developmental contexts.

text: "Inside–outside classification is widely used for geometry processing tasks
such as surface reconstruction, geometry completion,\r\nand calculating signed
distance fields. We introduce a new integral formulation of this problem, which
assigns confidence\r\nscores that points are inside or outside, given incomplete
boundary geometry. Even though our geometric construction does\r\nnot appear in
previous work, we show that it is unexpectedly linked to both the well-established
generalized winding number\r\n(GWN) and pseudonormal methods for geometry completion,
and it provably reduces to either one of them for specific values\r\nof a control
parameter. The results obtained with our method frequently outperform screened
Poisson surface reconstruction\r\n(PSR), GWN, and the pseudonormal method in terms
of quality, and are at least on par with them on all of our examples. Unlike\r\nthese
methods, our algorithm naturally extends to the multi-label setting, in which
regions with an arbitrary number of colors\r\nor physical materials can be reconstructed,
and non-manifold features such as T-junctions may appear in the interface and\r\nboundary
geometry"

text: Probing the possibility of entanglement generation through gravity offers
a path to tackle the question of whether gravitational fields possess a quantum
mechanical nature. A potential realization necessitates systems with low-frequency
dynamics at an optimal mass scale, for which the microgram-to-milligram range
is a strong contender. Here, after refining a figure-of-merit for the problem,
we present a 1-milligram torsional pendulum operating at 18 Hz. We demonstrate
laser cooling its motion from room temperature to 240 microkelvins, surpassing
by over 20-fold the coldest motions attained for oscillators ranging from micrograms
to kilograms. We quantify and contrast the utility of the current approach with
other platforms. The achieved performance and large improvement potential highlight
milligram-scale torsional pendulums as a powerful platform for precision measurements
relevant to future studies at the quantum-gravity interface.

text: During complex vocal interactions, different features of acoustic stimuli
are integrated to produce appropriate vocal responses,1 such as copying sounds
during vocal matching behavior in some animals.2,3,4,5,6,7,8,9,10,11,12 However,
little is known about the interplay and possible trade-offs between the different
temporal and spectral acoustic features during these vocal exchanges.2,13,14 Nightingales
can flexibly match the pitch of their tonal “whistle songs” in real time during
counter-singing duels.15,16 Here, we show that the syllable duration of whistle
playbacks could alter the song responses of wild nightingales, causing their whistle
duration distribution to shift toward the presented stimulus duration. When exposed
to whistle playbacks featuring unnatural combinations of pitch and duration, nightingales
demonstrate a flexible trade-off between pitch matching and temporal imitation,
yet they are constrained by their vocal repertoire. They selectively adapted their
vocal responses to approximate these novel stimuli, aligning them with their natural
whistle repertoire. We developed a computational model of nightingale whistle-matching
behavior that revealed a hierarchical organization of acoustic feature production.
During whistle matching, the feature integration process is constrained by the
duration of syllables, and pitch matching follows within this temporal framework,
forcing a trade-off between the two features. Our findings reveal a complex interplay
between the spectral and temporal domains that shapes song-matching behavior.

text: "Rapid local adaptation to new environments is critical for species persistence,
especially in introduced populations. The evolutionary success of these populations
is fundamentally dictated by the organization of genetic variation—the genomic
architecture—in the face of severe demographic constraints, such as the founder
effects and genetic bottlenecks that frequently accompany colonization. A central
question in evolutionary biology is whether rapid adaptation relies on major-effect
loci, such as chromosomal inversions, or on many small-effect loci dispersed across
the genome. Furthermore, the genomic architecture strongly influences the extent
to which evolutionary outcomes are predictable. Using introduced populations of
the marine snail, Littorina saxatilis, as a model, this thesis investigates how
genetic variation and genomic structure drive adaptation following introduction.
We employed a population genomics approach on experimentally and accidentally
introduced populations to dissect the specific genomic features that underpin
divergence in newly colonized environments.\r\n\r\nIn Chapter 2, we tested the
predictability of local adaptation through an uncommon 30-year transplant experiment
in nature. By distinguishing allele and chromosomal inversion frequency changes
from neutral expectations, we found that evolutionary change was highly predictable
at the macro-scale (phenotypes and chromosomal inversions), but less robust at
the level of individual collinear loci. This result demonstrates that evolution
can be predictable when a population possesses sufficient standing genetic variation
(SGV), with chromosomal inversions acting as key integrated units that facilitate
a rapid response to selection. Building on this, Chapter 3 applied whole-genome
sequencing to three accidentally introduced populations (Venice, San Francisco,
and Redwood City) to investigate their likely source and genomic patterns of divergence.
We identified genomic regions of remarkable divergence potentially associated
with local adaptation, and likely fuelled by SGV, while explicitly acknowledging
the difficulty in disentangling selection signals from the genome-wide effects
of demographic processes. Furthermore, we found that the divergence patterns relied
extensively on the collinear genome in these introduced populations, and less
clearly on the chromosomal inversions. This observation contrasts with local adaptation
observed in the experimental system that relied on both collinear loci and highly
selected chromosomal inversions, highlighting how demographic history and genomic
architecture influence the detectable signature of local adaptation.\r\n\r\nA
major limitation to conducting large-scale comparative evolutionary studies is
the lack of data standardization, which prevents the integration of community
knowledge and high-resolution environmental and genetic data. Chapter 4 addresses
this by developing a community database for the Littorina system. This platform
implements standardized protocols for the integration of diverse phenotypic and
environmental data from multiple Littorina species. Likewise, the platform also
centralizes the availability of associated genomic data through links to external
repositories. This database represents a crucial tool to test complex, large-scale
evolutionary hypotheses.\r\n\r\nCollectively, this thesis strongly reinforces
the fundamental importance of SGV as the raw material for successful local adaptation,
a conclusion supported by evidence in both experimental and accidental introductions.
Furthermore, this work highlights the critical role of the genomic architecture—specifically
chromosomal inversions—in driving the predictability and effectiveness of adaptive
responses. Our findings underscore how the interplay between SGV and genomic architecture
dictates the trajectory and detectability of evolution in colonizing populations,
while simultaneously providing a necessary tool to advance comparative evolutionary
genomics in emerging model organisms."

text: Copper chalcogenides offer high charge mobility and low lattice thermal conductivity
but suffer from structural instability due to dynamic Cu+ migration. Here, we
report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3)
nanocrystals (NCs), achieving precise control over phase, size, and morphology
through tailored precursor-ligand modulation. This strategy enabled systematic
exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation
of nucleation and growth, providing insight into phase modulation and dimensional
control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity
(∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles
calculations, consistent with experimental electronic and optical responses, predict
a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3
and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms
for advanced functional applications.

text: Modern experimental methods in programmable self-assembly make it possible
to precisely design particle concentrations, shapes and interactions. However,
more physical insight is needed before we can take full advantage of this vast
design space to assemble nanostructures with complex form and function. Here we
show how a substantial part of this design space can be quickly and comprehensively
understood by identifying a class of thermodynamic constraints that act on it.
These thermodynamic constraints form a high-dimensional convex polyhedron that
determines which nanostructures can be assembled at high equilibrium yield and
reveals limitations that govern the coexistence of structures. We validate our
predictions through detailed, quantitative assembly experiments of nanoscale particles
synthesized using DNA origami. Our results uncover physical relationships underpinning
many-component programmable self-assembly in equilibrium and form the basis for
robust inverse design, applicable to various systems from biological protein complexes
to synthetic nanomachines.

text: C(sp2)–heteroatom couplings operating via NiI/NiIII catalysis have emerged
as an alternative to canonical Pd0/PdII systems that require complex ligand architectures.
Despite intensive research efforts during the past decade, catalytic methods employing
this approach are still mostly confined to activated starting materials and require
high catalyst loadings due to the low catalytic activity of NiI and undesired
catalyst deactivation events. This article highlights recent advances in the field
toward solving these long-standing challenges. We survey strategies that streamline
the generation of catalytically competent NiI species from bench-stable NiII precatalysts,
and discuss mechanistic studies that shed light on deactivation pathways and the
rate-determining oxidative addition of aryl halides. In the final section, we
highlight recently developed synthetic methodologies, which provide evidence that
limitations can indeed be addressed by working at elevated temperatures, employing
alternative electrophiles, harnessing the benefits of additives, or fine-tuning
the metal’s reactivity through the ligand field.

text: We have addressed convective self‐aggregation (CSA) in steady and oscillating
sea surface temperature (SST) and solar radiation (SOLIN) cloud‐resolving model
simulations in a non‐rotating radiative‐convective equilibrium (RCE) framework.
Our experiment designs are motivated by land‐ocean heterogeneity of atmospheric
convection. The steady and oscillating forcings are idealizations of ocean and
land conditions, respectively, based on their differences in heat capacities.
In both kinds of simulations, the diurnal mean SST and SOLIN are the same, and
both SST and SOLIN are only varied in time (i.e., they are spatially homogeneous
at any given time). We find that diurnally oscillating forcing accelerates CSA.
Stronger long‐wave cooling in dry regions at night and during the warm SST phase
(late afternoon) both allow the long‐wave feedback, known to favor aggregation,
to intensify compared to steady forcing simulations. In addition to the long‐wave,
reduced short‐wave warming in dry regions (during the day) further enhances radiative
cooling there compared to moist regions. Overall, the radiative cooling is enhanced
in dry regions compared to neighboring moist convective regions. A dry subsidence
is driven by this net radiative (short‐wave plus long‐wave) cooling, consistent
with earlier work on CSA. Stronger radiative cooling allows stronger subsidence
which allows low‐level circulation to more efficiently transport moisture and
energy up‐gradient, driving convection to aggregate faster. We also note a sensitivity
of our experimental setup to initial conditions, more so at warmer SST. This stochastic
behavior might be critical in reconciling the differences of opinion regarding
the response of convection aggregation to oscillating SST forcing.

vineyards, and how tools from topological data analysis can illuminate problems
in mathematical physics. Central to this exploration is the question of how structure,
both geometric and topological, persists or changes under approximation, sampling,
or deformation. The work develops new approaches to skeletal and grid-based representations
of surfaces, reveals the full expressive capacity of persistence vineyards, and
applies topological methods to the longstanding problem of equilibria in electrostatic
fields. These threads braid together into a broader understanding of how topology
and geometry inform one another across theory, computation, and application.

text: 'The abundant population of little red dots (LRDs), compact objects with red
UV to optical colors and broad Balmer lines at high redshift, is revealing new
insights into the properties of early active galactic nuclei (AGN). Perhaps the
most surprising features of this population are the presence of Balmer absorption
and ubiquitous strong Balmer breaks. Recent models link these features to an active
supermassive black hole (SMBH) cocooned in very dense gas (NH ∼ 1024 cm−2). We
present a stringent test of such models using VLT/MUSE observations of A2744-45924,
the most luminous LRD known to date (LHα ≈ 1044 erg s−1), located behind the Abell-2744
lensing cluster at z = 4.464 (μ = 1.8). We detect a moderately extended Lyα nebula
(h ≈ 5.7 pkpc), spatially offset from the point-like Hα seen by JWST by ≈1.6 pkpc.
The Lyα emission is narrow (FWHM = 270 ± 15 km s−1), and faint (Lyα = 0.07Hα)
compared to Lyα nebulae typically observed around quasars of similar luminosity.
We detect compact N IV]λ1486 emission, spatially aligned with Hα, and a spatial
shift in the far-UV continuum matching the Lyα offset. We discuss that Hα and
Lyα have distinct physical origins: Hα originates from the AGN, while Lyα is powered
by star formation. In the environment of A2744-45924, we identified four extended
Lyα halos (Δz < 0.02, Δr < 100 pkpc). Their Lyα luminosities match the expectations
based on Hα emission, and show no evidence for radiation from A2744-45924 affecting
its surroundings. The lack of strong, compact, and broad Lyα and the absence of
a luminous extended halo, suggest that the UV AGN light is obscured by dense gas
cloaking the SMBH with a covering factor close to unity.'

text: "In recent years there has been a massive increase in the amount of data generated
in a\r\ndecentralized manner. Ever more powerful edge devices, such as smartphones,
have become\r\nubiquitous in most societies on earth. Through text typed, photos
taken and apps used,\r\nthese devices, which we refer to as clients, generate
enormous amounts of high quality and\r\ncomplex data. Moreover, the nature of
these devices means the data they generate is often\r\nsensitive and privacy concerns
prevent it being gathered and stored in a central location. This\r\npresents a
challenge to the modern machine learning paradigm that requires central access\r\nto
large amounts of data. Federated learning (FL) has emerged as one of the answers
to\r\nthis problem. Rather than bringing the data to the model, FL sends the model
to the data.\r\nModel training takes place on device, with periodically synchronized
updates, allowing data to\r\nremain locally stored. While this approach offers
significant privacy advantages it comes with\r\nits own set of unique challenges.
These include: data heterogeneity, the notion that different\r\ndevices generate
data in distinct ways which can negatively impact training dynamics; systems\r\nheterogeneity,
meaning that different devices may have differing hardware specifications; high\r\ncommunication
costs, which are induced by the repeated transferring of models over the\r\nnetwork
and low device computational power, which limits the use of larger models on device.\r\nIn
this thesis we present a range of methods for federated learning. We focus primarily
on\r\nthe challenge of data heterogeneity, though the methods presented are designed
to be well\r\nadapted to the other challenges of a federated setting, such as
the constraints of limited\r\ncompute and communication overhead. We first present
a method for explicitly modeling client\r\ndata heterogeneity. The approach formulates
clients as samples from a certain probability\r\ndistribution and infers the parameters
of this distribution from the available training clients.\r\nThis learned distribution
then represents the heterogeneity present among the clients and can\r\nbe sampled
from in order to create new simulated clients that are similar to the real clients
we\r\nhave observed so far. Following this we present two methods for directly
dealing with data\r\nheterogeneity through personalization. Highly heterogeneous
client data distributions can mean\r\nthat learning a single global model becomes
suboptimal, and some form of personalization of\r\nmodels to each individual client
is required. Our approaches are based around hypernetworks,\r\nwhich we use to
generate personalized model parameters without the need for additional\r\ntraining
or finetuning. In the first approach we focus on generating full parameterizations
of\r\nclient models using learned embeddings of client data and labels, with a
hypernetwork located\r\non the central server. In the second approach we address
the more challenging scenario where\r\nwe want to generate a personalized model
for a client without any label information. The\r\nhypernetwork is trained to
generate a low dimensional representation of a client’s personalized\r\nmodel
parameters, allowing it to be transferred to and run on the client devices. In
our final\r\npresented method, we change our focus and rather than aim to directly
address the challenge\r\nof data heterogeneity, we instead ensure we are unaffected
by it. This is done in the context\r\nof k-means clustering and we present a method
for federated clustering with a focus on added\r\nprivacy guarantees."

text: In aged humans and mice, hypobranched glycogen aggregates, known as polyglucosan
bodies (PGBs), accumulate in hippocampal astrocytes. While PGBs are linked to
cognitive decline in neurological diseases, they remain largely unstudied in the
context of typical aging. We show that PGBs arise in autophagy-dysregulated astrocytes
in the aged hippocampus, with substantial variation among 32 inbred BXD mouse
strains. Genetic mapping through quantitative trait locus analysis identified
a major locus (Pgb1) that modulates hippocampal PGB burden. Extensive transcriptomic
and proteomic datasets were produced for the aged hippocampus of the BXD family
to investigate the mechanism by which the Pgb1 locus modulates PGB burden. We
identified that Pgb1 contains allelic Smarcal1 and Usp37 variants and influences
PGB burden through trans-regulation of mRNA and protein expression levels, including
abundance of glycogen-mobilizing factor PYGB. Furthermore, comprehensive phenome-wide
association scans, transcriptomic analyses, and direct behavioral testing demonstrated
that cognition remains intact despite age-related PGB burden. A record of this
paper’s transparent peer review process is included in the supplemental information.

text: "Many white dwarfs are observed in compact double white dwarf binaries, and
through the emission of gravitational waves, a large fraction are destined to
merge. The merger remnants that do not explode in a Type Ia supernova are expected
to initially be rapidly rotating and highly magnetized. In this work, we present
our discovery of the variable white dwarf ZTF J200832.79+444939.67, hereafter
ZTF J2008+4449, as a likely merger remnant showing signs of circumstellar material
without a stellar or substellar companion. The nature of ZTF J2008+4449 as a merger
remnant is supported by its physical properties: it is hot (35 500 ± 300 K) and
massive (1.12 ± 0.03 M\r\n ⊙\r\n ),
rapidly rotating with a period of ≈6.6 minutes, and likely possesses exceptionally
strong magnetic fields (∼400−600 MG) at its surface. Remarkably, we detect a significant
period derivative of (1.80 ± 0.09)×10\r\n −12\r\n
\ s/s, indicating that the white dwarf is spinning down, and
a soft X-ray emission that is inconsistent with photospheric emission. As the
presence of a mass-transferring stellar or brown dwarf companion is excluded by
infrared photometry, the detected spin-down and X-ray emission could be tell-tale
signs of a magnetically driven wind or of interaction with circumstellar material,
possibly originating from the fallback of gravitationally bound merger ejecta
or from the tidal disruption of a planetary object. We also detect Balmer emission,
which requires the presence of ionized hydrogen in the vicinity of the white dwarf,
showing Doppler shifts as high as ≈2000 km s\r\n −1\r\n
\ . The unusual variability of the Balmer emission on the spin
period of the white dwarf is consistent with the trapping of a half ring of ionized
gas in the magnetosphere of the white dwarf.\r\n "

text: The advantageous characteristics attributed to the 19F nucleus have made it
a popular target for NMR once again in recent years. Aside from solution NMR,
an increasing number of studies have been conducted applying solid-state magic-angle-spinning
NMR to fluorine-labeled samples. Here, the high chemical shift anisotropy and
strong dipolar couplings can be utilized to get structural insights into proteins
and measure long distances. Despite increasing popularity and promising benefits,
the sensitivity of biomolecular 19F MAS NMR often suffers from slow longitudinal
T1 relaxation and therefore long recycle delays. In this work, we expand paramagnetic
doping, an approach commonly used to reduce proton T1 relaxation times, to 19F-labeled
biological samples. We study the effect of Gd(DTPA) and Gd(DTPA-BMA) on 19F and
13C T1 and T2 relaxation in a [5-19F13C]-tryptophan-labeled protein via 19F-detected
MAS NMR experiments. The observed paramagnetic relaxation enhancement substantially
reduces measurement times of 19F MAS NMR experiments without compromising resolution.
Additionally, we report the chemical-shift assignments of all four fluorotryptophan
signals in the 12 × 39 kDa large protein using a mutagenesis approach.

text: 'Depending on the type of flow, the transition to turbulence can take one
of two forms: either turbulence arises from a sequence of instabilities or from
the spatial proliferation of transiently chaotic domains, a process analogous
to directed percolation. The former scenario is commonly referred to as a supercritical
transition and frequently encountered in flows destabilized by body forces, whereas
the latter subcritical transition is common in shear flows. Both cases are inherently
continuous in a sense that the transformation from ordered laminar to fully turbulent
fluid motion is only accomplished gradually with flow speed. Here we show that
these established transition types do not account for the more general setting
of shear flows subject to body forces. The combination of the two continuous scenarios
leads to the attenuation of spatial coupling; with increasing forcing amplitude,
the transition becomes increasingly sharp and eventually discontinuous. We argue
that the suppression of laminar–turbulent coexistence and the approach towards
a discontinuous phase transition potentially apply to a broad range of situations
including flows subject to, for example, buoyancy, centrifugal or electromagnetic
forces.'
