text: Asteroseismology has transformed stellar astrophysics. Red giant asteroseismology
is a prime example, with oscillation periods and amplitudes that are readily detectable
with time-domain space-based telescopes. These oscillations can be used to infer
masses, ages and radii for large numbers of stars, providing unique constraints
on stellar populations in our galaxy. The cadence, duration, and spatial resolution
of the Roman galactic bulge time-domain survey (GBTDS) are well-suited for asteroseismology
and will probe an important population not studied by prior missions. We identify
photometric precision as a key requirement for realizing the potential of asteroseismology
with Roman. A precision of 1 mmag per 15-min cadence or better for saturated stars
will enable detections of the populous red clump star population in the Galactic
bulge. If the survey efficiency is better than expected, we argue for repeat observations
of the same fields to improve photometric precision, or covering additional fields
to expand the stellar population reach if the photometric precision for saturated
stars is better than 1 mmag. Asteroseismology is relatively insensitive to the
timing of the observations during the mission, and the prime red clump targets
can be observed in a single 70 day campaign in any given field. Complementary
stellar characterization, particularly astrometry tied to the Gaia system, will
also dramatically expand the diagnostic power of asteroseismology. We also highlight
synergies to Roman GBTDS exoplanet science using transits and microlensing.

text: Stars strongly impact their environment, and shape structures on all scales
throughout the universe, in a process known as "feedback." Due to the complexity
of both stellar evolution and the physics of larger astrophysical structures,
there remain many unanswered questions about how feedback operates and what we
can learn about stars by studying their imprint on the wider universe. In this
white paper, we summarize discussions from the Lorentz Center meeting "Bringing
Stellar Evolution and Feedback Together" in 2022 April and identify key areas
where further dialog can bring about radical changes in how we view the relationship
between stars and the universe they live in.

text: In previous work, we identified a population of 38 cool and luminous variable
stars in the Magellanic Clouds and examined 11 in detail in order to classify
them as either Thorne–Żytkow objects (TŻOs; red supergiants with a neutron star
cores) or super-asymptotic giant branch (sAGB) stars (the most massive stars that
will not undergo core collapse). This population includes HV 2112, a peculiar
star previously considered in other works to be either a TŻO or high-mass asymptotic
giant branch (AGB) star. Here we continue this investigation, using the kinematic
and radio environments and local star formation history of these stars to place
constraints on the age of the progenitor systems and the presence of past supernovae.
These stars are not associated with regions of recent star formation, and we find
no evidence of past supernovae at their locations. Finally, we also assess the
presence of heavy elements and lithium in their spectra compared to red supergiants.
We find strong absorption in Li and s-process elements compared to RSGs in most
of the sample, consistent with sAGB nucleosynthesis, while HV 2112 shows additional
strong lines associated with TŻO nucleosynthesis. Coupled with our previous mass
estimates, the results are consistent with the stars being massive (∼4–6.5 M⊙)
or sAGB (∼6.5–12 M⊙) stars in the thermally pulsing phase, providing crucial observations
of the transition between low- and high-mass stellar populations. HV 2112 is more
ambiguous; it could either be a maximally massive sAGB star, or a TŻO if the minimum
mass for stability extends down to ≲13 M⊙.

text: The many-body localization (MBL) proximity effect is an intriguing phenomenon
where a thermal bath localizes due to the interaction with a disordered system.
The interplay of thermal and nonergodic behavior in these systems gives rise to
a rich phase diagram, whose exploration is an active field of research. In this
paper, we study a bosonic Hubbard model featuring two particle species representing
the bath and the disordered system. Using state-of-the-art numerical techniques,
we investigate the dynamics of the model in different regimes, based on which
we obtain a tentative phase diagram as a function of coupling strength and bath
size. When the bath is composed of a single particle, we observe clear signatures
of a transition from an MBL proximity effect to a delocalized phase. Increasing
the bath size, however, its thermalizing effect becomes stronger and eventually
the whole system delocalizes in the range of moderate interaction strengths studied.
In this regime, we characterize particle transport, revealing diffusive behavior
of the originally localized bosons.

text: We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation
energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams,
we sample the Møller-Plesset (MPn) perturbation series, obtaining accurate correlation
energies up to n=5, with quadratic scaling in the number of basis functions. Our
technique reduces the computational complexity of the molecular many-fermion correlation
problem, opening up the possibility of low-scaling, accurate stochastic computations
for a wide class of many-body systems described by Hugenholtz diagrams.

text: "Bundling crossings is a strategy which can enhance the readability\r\nof
graph drawings. In this paper we consider good drawings, i.e., we require that\r\nany
two edges have at most one common point which can be a common vertex or a\r\ncrossing.
Our main result is that there is a polynomial-time algorithm to compute an\r\n8-approximation
of the bundled crossing number of a good drawing with no toothed\r\nhole. In general
the number of toothed holes has to be added to the 8-approximation.\r\nIn the
special case of circular drawings the approximation factor is 8, this improves\r\nupon
the 10-approximation of Fink et al. [14]. Our approach also works with the same\r\napproximation
factor for families of pseudosegments, i.e., curves intersecting at most\r\nonce.
We also show how to compute a 9/2-approximation when the intersection graph of\r\nthe
pseudosegments is bipartite and has no toothed hole."

text: When in equilibrium, thermal forces agitate molecules, which then diffuse,
collide and bind to form materials. However, the space of accessible structures
in which micron-scale particles can be organized by thermal forces is limited,
owing to the slow dynamics and metastable states. Active agents in a passive fluid
generate forces and flows, forming a bath with active fluctuations. Two unanswered
questions are whether those active agents can drive the assembly of passive components
into unconventional states and which material properties they will exhibit. Here
we show that passive, sticky beads immersed in a bath of swimming Escherichia
coli bacteria aggregate into unconventional clusters and gels that are controlled
by the activity of the bath. We observe a slow but persistent rotation of the
aggregates that originates in the chirality of the E. coli flagella and directs
aggregation into structures that are not accessible thermally. We elucidate the
aggregation mechanism with a numerical model of spinning, sticky beads and reproduce
quantitatively the experimental results. We show that internal activity controls
the phase diagram and the structure of the aggregates. Overall, our results highlight
the promising role of active baths in designing the structural and mechanical
properties of materials with unconventional phases.

text: Conflicts and natural disasters affect entire populations of the countries
involved and, in addition to the thousands of lives destroyed, have a substantial
negative impact on the scientific advances these countries provide. The unprovoked
invasion of Ukraine by Russia, the devastating earthquake in Turkey and Syria,
and the ongoing conflicts in the Middle East are just a few examples. Millions
of people have been killed or displaced, their futures uncertain. These events
have resulted in extensive infrastructure collapse, with loss of electricity,
transportation, and access to services. Schools, universities, and research centers
have been destroyed along with decades’ worth of data, samples, and findings.
Scholars in disaster areas face short- and long-term problems in terms of what
they can accomplish now for obtaining grants and for employment in the long run.
In our interconnected world, conflicts and disasters are no longer a local problem
but have wide-ranging impacts on the entire world, both now and in the future.
Here, we focus on the current and ongoing impact of war on the scientific community
within Ukraine and from this draw lessons that can be applied to all affected
countries where scientists at risk are facing hardship. We present and classify
examples of effective and feasible mechanisms used to support researchers in countries
facing hardship and discuss how these can be implemented with help from the international
scientific community and what more is desperately needed. Reaching out, providing
accessible training opportunities, and developing collaborations should increase
inclusion and connectivity, support scientific advancements within affected communities,
and expedite postwar and disaster recovery.

text: Characterizing and controlling entanglement in quantum materials is crucial
for the development of next-generation quantum technologies. However, defining
a quantifiable figure of merit for entanglement in macroscopic solids is theoretically
and experimentally challenging. At equilibrium the presence of entanglement can
be diagnosed by extracting entanglement witnesses from spectroscopic observables
and a nonequilibrium extension of this method could lead to the discovery of novel
dynamical phenomena. Here, we propose a systematic approach to quantify the time-dependent
quantum Fisher information and entanglement depth of transient states of quantum
materials with time-resolved resonant inelastic x-ray scattering. Using a quarter-filled
extended Hubbard model as an example, we benchmark the efficiency of this approach
and predict a light-enhanced many-body entanglement due to the proximity to a
phase boundary. Our work sets the stage for experimentally witnessing and controlling
entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.

text: Many-body entanglement in condensed matter systems can be diagnosed from equilibrium
response functions through the use of entanglement witnesses and operator-specific
quantum bounds. Here, we investigate the applicability of this approach for detecting
entangled states in quantum systems driven out of equilibrium. We use a multipartite
entanglement witness, the quantum Fisher information, to study the dynamics of
a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb
interaction. Our results show that the quantum Fisher information is able to witness
distinct signatures of multipartite entanglement both near and far from equilibrium
that are robust against decoherence. We discuss implications of these findings
for probing entanglement in light-driven quantum materials with time-resolved
optical and x-ray scattering methods.

text: 'Traditionally, nuclear spin is not considered to affect biological processes.
Recently, this has changed as isotopic fractionation that deviates from classical
mass dependence was reported both in vitro and in vivo. In these cases, the isotopic
effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects
using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial
dioxygen production system and biological aquaporin channels in cells. We observe
that oxygen dynamics in chiral environments (in particular its transport) depend
on nuclear spin, suggesting future applications for controlled isotope separation
to be used, for instance, in NMR. To demonstrate the mechanism behind our findings,
we formulate theoretical models based on a nuclear-spin-enhanced switch between
electronic spin states. Accounting for the role of nuclear spin in biology can
provide insights into the role of quantum effects in living systems and help inspire
the development of future biotechnology solutions.'

text: Membranes are essential for life. They act as semi-permeable boundaries that
define cells and organelles. In addition, their surfaces actively participate
in biochemical reaction networks, where they confine proteins, align reaction
partners, and directly control enzymatic activities. Membrane-localized reactions
shape cellular membranes, define the identity of organelles, compartmentalize
biochemical processes, and can even be the source of signaling gradients that
originate at the plasma membrane and reach into the cytoplasm and nucleus. The
membrane surface is, therefore, an essential platform upon which myriad cellular
processes are scaffolded. In this review, we summarize our current understanding
of the biophysics and biochemistry of membrane-localized reactions with particular
focus on insights derived from reconstituted and cellular systems. We discuss
how the interplay of cellular factors results in their self-organization, condensation,
assembly, and activity, and the emergent properties derived from them.

text: Robust oxygenic photosynthesis requires a suite of accessory factors to ensure
efficient assembly and repair of the oxygen-evolving photosystem two (PSII) complex.
The highly conserved Ycf48 assembly factor binds to the newly synthesized D1 reaction
center polypeptide and promotes the initial steps of PSII assembly, but its binding
site is unclear. Here we use cryo-electron microscopy to determine the structure
of a cyanobacterial PSII D1/D2 reaction center assembly complex with Ycf48 attached.
Ycf48, a 7-bladed beta propeller, binds to the amino-acid residues of D1 that
ultimately ligate the water-oxidising Mn4CaO5 cluster, thereby preventing the
premature binding of Mn2+ and Ca2+ ions and protecting the site from damage. Interactions
with D2 help explain how Ycf48 promotes assembly of the D1/D2 complex. Overall,
our work provides valuable insights into the early stages of PSII assembly and
the structural changes that create the binding site for the Mn4CaO5 cluster.

text: Tissue morphogenesis and patterning during development involve the segregation
of cell types. Segregation is driven by differential tissue surface tensions generated
by cell types through controlling cell-cell contact formation by regulating adhesion
and actomyosin contractility-based cellular cortical tensions. We use vertebrate
tissue cell types and zebrafish germ layer progenitors as in vitro models of 3-dimensional
heterotypic segregation and developed a quantitative analysis of their dynamics
based on 3D time-lapse microscopy. We show that general inhibition of actomyosin
contractility by the Rho kinase inhibitor Y27632 delays segregation. Cell type-specific
inhibition of non-muscle myosin2 activity by overexpression of myosin assembly
inhibitor S100A4 reduces tissue surface tension, manifested in decreased compaction
during aggregation and inverted geometry observed during segregation. The same
is observed when we express a constitutively active Rho kinase isoform to ubiquitously
keep actomyosin contractility high at cell-cell and cell-medium interfaces and
thus overriding the interface-specific regulation of cortical tensions. Tissue
surface tension regulation can become an effective tool in tissue engineering.

text: 'Over the last two decades, a significant line of work in theoretical algorithms
has made progress in solving linear systems of the form Lx=b, where L is the Laplacian
matrix of a weighted graph with weights w(i,j)>0 on the edges. The solution x
of the linear system can be interpreted as the potentials of an electrical flow
in which the resistance on edge (i, j) is 1/w(i, j). Kelner et al. (in: Proceedings
of the 45th Annual ACM Symposium on the Theory of Computing, pp 911–920, 2013.
https://doi.org/10.1145/2488608.2488724) give a combinatorial, near-linear time
algorithm that maintains the Kirchoff Current Law, and gradually enforces the
Kirchoff Potential Law by updating flows around cycles (cycle toggling). In this
paper, we consider a dual version of the algorithm that maintains the Kirchoff
Potential Law, and gradually enforces the Kirchoff Current Law by cut toggling:
each iteration updates all potentials on one side of a fundamental cut of a spanning
tree by the same amount. We prove that this dual algorithm also runs in a near-linear
number of iterations. We show, however, that if we abstract cut toggling as a
natural data structure problem, this problem can be reduced to the online vector–matrix-vector
problem, which has been conjectured to be difficult for dynamic algorithms (Henzinger
et al., in: Proceedings of the 47th Annual ACM Symposium on the Theory of Computing,
pp 21–30, 2015. https://doi.org/10.1145/2746539.2746609). The conjecture implies
that the data structure does not have an O(n1−ϵ) time algorithm for any ϵ>0, and
thus a straightforward implementation of the cut-toggling algorithm requires essentially
linear time per iteration. To circumvent the lower bound, we batch update steps,
and perform them simultaneously instead of sequentially. An appropriate choice
of batching leads to an O˜(m1.5) time cut-toggling algorithm for solving Laplacian
systems. Furthermore, we show that if we sparsify the graph and call our algorithm
recursively on the Laplacian system implied by batching and sparsifying, we can
reduce the running time to O(m1+ϵ) for any ϵ>0. Thus, the dual cut-toggling algorithm
can achieve (almost) the same running time as its primal cycle-toggling counterpart.'

text: "Females and males across species are subject to divergent selective pressures
arising\r\nfrom di↵erent reproductive interests and ecological niches. This often
translates into a\r\nintricate array of sex-specific natural and sexual selection
on traits that have a shared\r\ngenetic basis between both sexes, causing a genetic
sexual conflict. The resolution of\r\nthis conflict mostly relies on the evolution
of sex-specific expression of the shared genes,\r\nleading to phenotypic sexual
dimorphism. Such sex-specific gene expression is thought\r\nto evolve via modifications
of the genetic networks ultimately linked to sex-determining\r\ntranscription
factors. Although much empirical and theoretical evidence supports this\r\nstandard
picture of the molecular basis of sexual conflict resolution, there still are
a\r\nfew open questions regarding the complex array of selective forces driving
phenotypic\r\ndi↵erentiation between the sexes, as well as the molecular mechanisms
underlying sexspecific adaptation. I address some of these open questions in my
PhD thesis.\r\nFirst, how do patterns of phenotypic sexual dimorphism vary within
populations,\r\nas a response to the temporal and spatial changes in sex-specific
selective forces? To\r\ntackle this question, I analyze the patterns of sex-specific
phenotypic variation along\r\nthree life stages and across populations spanning
the whole geographical range of Rumex\r\nhastatulus, a wind-pollinated angiosperm,
in the first Chapter of the thesis.\r\nSecond, how do gene expression patterns
lead to phenotypic dimorphism, and what\r\nare the molecular mechanisms underlying
the observed transcriptomic variation? I\r\naddress this question by examining
the sex- and tissue-specific expression variation in\r\nnewly-generated datasets
of sex-specific expression in heads and gonads of Drosophila\r\nmelanogaster.
I additionally used two complementary approaches for the study of the\r\ngenetic
basis of sex di↵erences in gene expression in the second and third Chapters of\r\nthe
thesis.\r\nThird, how does intersex correlation, thought to be one of the main
aspects constraining the ability for the two sexes to decouple, interact with
the evolution of sexual\r\ndimorphism? I develop models of sex-specific stabilizing
selection, mutation and drift\r\nto formalize common intuition regarding the patterns
of covariation between intersex\r\ncorrelation and sexual dimorphism in the fourth
Chapter of the thesis.\r\nAlltogether, the work described in this PhD thesis provides
useful insights into the\r\nlinks between genetic, transcriptomic and phenotypic
layers of sex-specific variation,\r\nand contributes to our general understanding
of the dynamics of sexual dimorphism\r\nevolution."

text: Hyperproperties are properties that relate multiple execution traces. Previous
work on monitoring hyperproperties focused on synchronous hyperproperties, usually
specified in HyperLTL. When monitoring synchronous hyperproperties, all traces
are assumed to proceed at the same speed. We introduce (multi-trace) prefix transducers
and show how to use them for monitoring synchronous as well as, for the first
time, asynchronous hyperproperties. Prefix transducers map multiple input traces
into one or more output traces by incrementally matching prefixes of the input
traces against expressions similar to regular expressions. The prefixes of different
traces which are consumed by a single matching step of the monitor may have different
lengths. The deterministic and executable nature of prefix transducers makes them
more suitable as an intermediate formalism for runtime verification than logical
specifications, which tend to be highly non-deterministic, especially in the case
of asynchronous hyperproperties. We report on a set of experiments about monitoring
asynchronous version of observational determinism.

text: "The regulatory architecture of gene expression is known to differ substantially
between sexes in Drosophila, but most studies performed\r\nso far used whole-body
data and only single crosses, which may have limited their scope to detect patterns
that are robust across tissues\r\nand biological replicates. Here, we use allele-specific
gene expression of parental and reciprocal hybrid crosses between 6 Drosophila\r\nmelanogaster
inbred lines to quantify cis- and trans-regulatory variation in heads and gonads
of both sexes separately across 3 replicate\r\ncrosses. Our results suggest that
female and male heads, as well as ovaries, have a similar regulatory architecture.
On the other hand,\r\ntestes display more and substantially different cis-regulatory
effects, suggesting that sex differences in the regulatory architecture that\r\nhave
been previously observed may largely derive from testis-specific effects. We also
examine the difference in cis-regulatory variation\r\nof genes across different
levels of sex bias in gonads and heads. Consistent with the idea that intersex
correlations constrain expression\r\nand can lead to sexual antagonism, we find
more cis variation in unbiased and moderately biased genes in heads. In ovaries,
reduced cis\r\nvariation is observed for male-biased genes, suggesting that cis
variants acting on these genes in males do not lead to changes in ovary\r\nexpression.
Finally, we examine the dominance patterns of gene expression and find that sex-
and tissue-specific patterns of inheritance\r\nas well as trans-regulatory variation
are highly variable across biological crosses, although these were performed in
highly controlled\r\nexperimental conditions. This highlights the importance of
using various genetic backgrounds to infer generalizable patterns."
