text: We consider the least singular value of a large random matrix with real or
complex i.i.d. Gaussian entries shifted by a constant z∈C. We prove an optimal
lower tail estimate on this singular value in the critical regime where z is around
the spectral edge, thus improving the classical bound of Sankar, Spielman and
Teng (SIAM J. Matrix Anal. Appl. 28:2 (2006), 446–476) for the particular shift-perturbation
in the edge regime. Lacking Brézin–Hikami formulas in the real case, we rely on
the superbosonization formula (Comm. Math. Phys. 283:2 (2008), 343–395).

text: We call a continuous self-map that reveals itself through a discrete set of
point-value pairs a sampled dynamical system. Capturing the available information
with chain maps on Delaunay complexes, we use persistent homology to quantify
the evidence of recurrent behavior. We establish a sampling theorem to recover
the eigenspaces of the endomorphism on homology induced by the self-map. Using
a combinatorial gradient flow arising from the discrete Morse theory for Čech
and Delaunay complexes, we construct a chain map to transform the problem from
the natural but expensive Čech complexes to the computationally efficient Delaunay
triangulations. The fast chain map algorithm has applications beyond dynamical
systems.

text: We introduce a new graph problem, the token dropping game, and we show how
to solve it efficiently in a distributed setting. We use the token dropping game
as a tool to design an efficient distributed algorithm for the stable orientation
problem, which is a special case of the more general locally optimal semi-matching
problem. The prior work by Czygrinow et al. (DISC 2012) finds a locally optimal
semi-matching in O(Δ⁵) rounds in graphs of maximum degree Δ, which directly implies
an algorithm with the same runtime for stable orientations. We improve the runtime
to O(Δ⁴) for stable orientations and prove a lower bound of Ω(Δ) rounds.

text: "We consider the following dynamic load-balancing process: given an underlying
graph G with n nodes, in each step t≥ 0, one unit of load is created, and placed
at a randomly chosen graph node. In the same step, the chosen node picks a random
neighbor, and the two nodes balance their loads by averaging them. We are interested
in the expected gap between the minimum and maximum loads at nodes as the process
progresses, and its dependence on n and on the graph structure. Variants of the
above graphical balanced allocation process have been studied previously by Peres,
Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and
Sun, 2015]. These authors left as open the question of characterizing the gap
in the case of cycle graphs in the dynamic case, where weights are created during
the algorithm’s execution. For this case, the only known upper bound is of \U0001D4AA(n
log n), following from a majorization argument due to [Peres et al., 2015], which
analyzes a related graphical allocation process. In this paper, we provide an
upper bound of \U0001D4AA (√n log n) on the expected gap of the above process
for cycles of length n. We introduce a new potential analysis technique, which
enables us to bound the difference in load between k-hop neighbors on the cycle,
for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds
the maximum value of the gap by bounding its value across all possible subsets
of a certain structure, and recursively bounding the gaps within each subset.
We provide analytical and experimental evidence that our upper bound on the gap
is tight up to a logarithmic factor."

text: "Two plane drawings of geometric graphs on the same set of points are called
disjoint compatible if their union is plane and they do not have an edge in common.
For a given set S of 2n points two plane drawings of perfect matchings M1 and
M2 (which do not need to be disjoint nor compatible) are disjoint tree-compatible
if there exists a plane drawing of a spanning tree T on S which is disjoint compatible
to both M1 and M2.\r\nWe show that the graph of all disjoint tree-compatible perfect
geometric matchings on 2n points in convex position is connected if and only if
2n ≥ 10. Moreover, in that case the diameter\r\nof this graph is either 4 or 5,
independent of n."

text: Coinfections with multiple pathogens can result in complex within-host dynamics
affecting virulence and transmission. Whilst multiple infections are intensively
studied in solitary hosts, it is so far unresolved how social host interactions
interfere with pathogen competition, and if this depends on coinfection diversity.
We studied how the collective disease defenses of ants – their social immunity
– influence pathogen competition in coinfections of same or different fungal
pathogen species. Social immunity reduced virulence for all pathogen combinations,
but interfered with spore production only in different-species coinfections. Here,
it decreased overall pathogen sporulation success, whilst simultaneously increasing
co-sporulation on individual cadavers and maintaining a higher pathogen diversity
at the community-level. Mathematical modeling revealed that host sanitary care
alone can modulate competitive outcomes between pathogens, giving advantage to
fast-germinating, thus less grooming-sensitive ones. Host social interactions
can hence modulate infection dynamics in coinfected group members, thereby altering
pathogen communities at the host- and population-level.

text: Domestication is a human-induced selection process that imprints the genomes
of domesticated populations over a short evolutionary time scale, and that occurs
in a given demographic context. Reconstructing historical gene flow, effective
population size changes and their timing is therefore of fundamental interest
to understand how plant demography and human selection jointly shape genomic divergence
during domestication. Yet, the comparison under a single statistical framework
of independent domestication histories across different crop species has been
little evaluated so far. Thus, it is unclear whether domestication leads to convergent
demographic changes that similarly affect crop genomes. To address this question,
we used existing and new transcriptome data on three crop species of Solanaceae
(eggplant, pepper and tomato), together with their close wild relatives. We fitted
twelve demographic models of increasing complexity on the unfolded joint allele
frequency spectrum for each wild/crop pair, and we found evidence for both shared
and species-specific demographic processes between species. A convergent history
of domestication with gene-flow was inferred for all three species, along with
evidence of strong reduction in the effective population size during the cultivation
stage of tomato and pepper. The absence of any reduction in size of the crop in
eggplant stands out from the classical view of the domestication process; as does
the existence of a “protracted period” of management before cultivation. Our results
also suggest divergent management strategies of modern cultivars among species
as their current demography substantially differs. Finally, the timing of domestication
is species-specific and supported by the few historical records available.

text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
found across temperate regions of the globe. This allows us to study "replicated"
instances of secondary contact between closely-related species. Previous work
on this complex has shown that local introgression is both widespread and highly
heterogeneous, and has identified SNPs that are outliers of differentiation between
lineages. Here, we developed an ancestry-informative panel of such SNPs. We then
compared their frequencies in newly-sampled populations, including samples from
within the hybrid zones, and parental populations at different distances from
the contact. Results show that close to the hybrid zones, some outlier loci are
near to fixation for the heterospecific allele, suggesting enhanced local introgression,
or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
treating local parental populations as the reference, reveal a globally high concordance
among loci, albeit with a few signals of asymmetric introgression. Enhanced local
introgression at specific loci is consistent with the early transfer of adaptive
variants after contact, possibly including asymmetric bi-stable variants (Dobzhansky-Muller
incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
escaped one barrier, however, these variants can be trapped or delayed at the
next barrier, confining the introgression locally. These results shed light on
the decay of species barriers during phases of contact.

text: "In nature, light is harvested by photoactive proteins to drive a range of
biological processes, including photosynthesis, phototaxis, vision, and ultimately
life. Bacteriorhodopsin, for example, is a protein embedded within archaeal cell
membranes that binds the chromophore retinal within its hydrophobic pocket. Exposure
to light triggers regioselective photoisomerization of the confined retinal, which
in turn initiates a cascade of conformational changes within the protein, triggering
proton flux against the concentration gradient, providing the microorganisms with
the energy to live. We are inspired by these functions in nature to harness light
energy using synthetic photoswitches under confinement. Like retinal, synthetic
photoswitches require some degree of conformational flexibility to isomerize.
In nature, the conformational change associated with retinal isomerization is
accommodated by the structural flexibility of the opsin host, yet it results in
steric communication between the chromophore and the protein. Similarly, we strive
to design systems wherein isomerization of confined photoswitches results in steric
communication between a photoswitch and its confining environment. To achieve
this aim, a balance must be struck between molecular crowding and conformational
freedom under confinement: too much crowding prevents switching, whereas too much
freedom resembles switching of isolated molecules in solution, preventing communication.\r\n\r\nIn
this Account, we discuss five classes of synthetic light-switchable compounds—diarylethenes,
anthracenes, azobenzenes, spiropyrans, and donor–acceptor Stenhouse adducts—comparing
their behaviors under confinement and in solution. The environments employed to
confine these photoswitches are diverse, ranging from planar surfaces to nanosized
cavities within coordination cages, nanoporous frameworks, and nanoparticle aggregates.
The trends that emerge are primarily dependent on the nature of the photoswitch
and not on the material used for confinement. In general, we find that photoswitches
requiring less conformational freedom for switching are, as expected, more straightforward
to isomerize reversibly under confinement. Because these compounds undergo only
small structural changes upon isomerization, however, switching does not propagate
into communication with their environment. Conversely, photoswitches that require
more conformational freedom are more challenging to switch under confinement but
also can influence system-wide behavior.\r\n\r\nAlthough we are primarily interested
in the effects of geometric constraints on photoswitching under confinement, additional
effects inevitably emerge when a compound is removed from solution and placed
within a new, more crowded environment. For instance, we have found that compounds
that convert to zwitterionic isomers upon light irradiation often experience stabilization
of these forms under confinement. This effect results from the mutual stabilization
of zwitterions that are brought into close proximity on surfaces or within cavities.
Furthermore, photoswitches can experience preorganization under confinement, influencing
the selectivity and efficiency of their photoreactions. Because intermolecular
interactions arising from confinement cannot be considered independently from
the effects of geometric constraints, we describe all confinement effects concurrently
throughout this Account."

text: Aggregation of organic molecules can drastically affect their physicochemical
properties. For instance, the optical properties of BODIPY dyes are inherently
related to the degree of aggregation and the mutual orientation of BODIPY units
within these aggregates. Whereas the noncovalent aggregation of various BODIPY
dyes has been studied in diverse media, the ill-defined nature of these aggregates
has made it difficult to elucidate the structure–property relationships. Here,
we studied the encapsulation of three structurally simple BODIPY derivatives within
the hydrophobic cavity of a water-soluble, flexible PdII6L4 coordination cage.
The cavity size allowed for the selective encapsulation of two dye molecules,
irrespective of the substitution pattern on the BODIPY core. Working with a model,
a pentamethyl-substituted derivative, we found that the mutual orientation of
two BODIPY units in the cage’s cavity was remarkably similar to that in the crystalline
state of the free dye, allowing us to isolate and characterize the smallest possible
noncovalent H-type BODIPY aggregate, namely, an H-dimer. Interestingly, a CF3-substituted
BODIPY, known for forming J-type aggregates, was also encapsulated as an H-dimer.
Taking advantage of the dynamic nature of encapsulation, we developed a system
in which reversible switching between H- and J-aggregates can be induced for multiple
cycles simply by addition and subsequent destruction of the cage. We expect that
the ability to rapidly and reversibly manipulate the optical properties of supramolecular
inclusion complexes in aqueous media will open up avenues for developing detection
systems that operate within biological environments.

text: Temporal activation of biological processes by visible light and subsequent
return to an inactive state in the absence of light is an essential characteristic
of photoreceptor cells. Inspired by these phenomena, light-responsive materials
are very attractive due to the high spatiotemporal control of light irradiation,
with light being able to precisely orchestrate processes repeatedly over many
cycles. Herein, it is reported that light-driven proton transfer triggered by
a merocyanine-based photoacid can be used to modulate the permeability of pH-responsive
polymersomes through cyclic, temporally controlled protonation and deprotonation
of the polymersome membrane. The membranes can undergo repeated light-driven swelling–contraction
cycles without losing functional effectiveness. When applied to enzyme loaded-nanoreactors,
this membrane responsiveness is used for the reversible control of enzymatic reactions.
This combination of the merocyanine-based photoacid and pH-switchable nanoreactors
results in rapidly responding and versatile supramolecular systems successfully
used to switch enzymatic reactions ON and OFF on demand.

text: Photochromic molecules undergo reversible isomerization upon irradiation with
light at different wavelengths, a process that can alter their physical and chemical
properties. For instance, dihydropyrene (DHP) is a deep-colored compound that
isomerizes to light-brown cyclophanediene (CPD) upon irradiation with visible
light. CPD can then isomerize back to DHP upon irradiation with UV light or thermally
in the dark. Conversion between DHP and CPD is thought to proceed via a biradical
intermediate; bimolecular events involving this unstable intermediate thus result
in rapid decomposition and poor cycling performance. Here, we show that the reversible
isomerization of DHP can be stabilized upon confinement within a PdII6L4 coordination
cage. By protecting this reactive intermediate using the cage, each isomerization
reaction proceeds to higher yield, which significantly decreases the fatigue experienced
by the system upon repeated photocycling. Although molecular confinement is known
to help stabilize reactive species, this effect is not typically employed to protect
reactive intermediates and thus improve reaction yields. We envisage that performing
reactions under confinement will not only improve the cyclic performance of photochromic
molecules, but may also increase the amount of product obtainable from traditionally
low-yielding organic reactions.

text: Photoswitchable molecules are employed for many applications, from the development
of active materials to the design of stimuli-responsive molecular systems and
light-powered molecular machines. To fully exploit their potential, we must learn
ways to control the mechanism and kinetics of their photoinduced isomerization.
One possible strategy involves confinement of photoresponsive switches such as
azobenzenes or spiropyrans within crowded molecular environments, which may allow
control over their light-induced conversion. However, the molecular factors that
influence and control the switching process under realistic conditions and within
dynamic molecular regimes often remain difficult to ascertain. As a case study,
here we have employed molecular models to probe the isomerization of azobenzene
guests within a Pd(II)-based coordination cage host in water. Atomistic molecular
dynamics and metadynamics simulations allow us to characterize the flexibility
of the cage in the solvent, the (rare) guest encapsulation and release events,
and the relative probability/kinetics of light-induced isomerization of azobenzene
analogues in these host–guest systems. In this way, we can reconstruct the mechanism
of azobenzene switching inside the cage cavity and explore key molecular factors
that may control this event. We obtain a molecular-level insight on the effects
of crowding and host–guest interactions on azobenzene isomerization. The detailed
picture elucidated by this study may enable the rational design of photoswitchable
systems whose reactivity can be controlled via host–guest interactions.

text: Binary interaction can cause stellar envelopes to be stripped, which significantly
reduces the radius of the star. The orbit of a binary composed of a stripped star
and a compact object can therefore be so tight that the gravitational radiation
the system produces reaches frequencies accessible to the Laser Interferometer
Space Antenna (LISA). Two such stripped stars in tight orbits with white dwarfs
are known so far (ZTF J2130+4420 and CD−30°11223), but many more are expected
to exist. These binaries provide important constraints for binary evolution models
and may be used as LISA verification sources. We develop a Monte Carlo code that
uses detailed evolutionary models to simulate the Galactic population of stripped
stars in tight orbits with either neutron star or white dwarf companions. We predict
0–100 stripped star + white dwarf binaries and 0–4 stripped star + neutron star
binaries with a signal-to-noise ratio >5 after 10 yr of observations with LISA.
More than 90% of these binaries are expected to show large radial velocity shifts
of ≳200 $\,\mathrm{km}\,{{\rm{s}}}^{-1}$, which are spectroscopically detectable.
Photometric variability due to tidal deformation of the stripped star is also
expected and has been observed in ZTF J2130+4420 and CD−30°11223. In addition,
the stripped star + neutron star binaries are expected to be X-ray bright with
LX ≳ 1033–1036 $\,\mathrm{erg}\,{{\rm{s}}}^{-1}$. Our results show that stripped
star binaries are promising multimessenger sources for the upcoming electromagnetic
and gravitational wave facilities.

text: High-resolution numerical simulations including feedback and aimed at calculating
the escape fraction (fesc) of hydrogen-ionizing photons often assume stellar radiation
based on single-stellar population synthesis models. However, strong evidence
suggests the binary fraction of massive stars is ≳70%. Moreover, simulations so
far have yielded values of fesc falling only on the lower end of the ∼10%–20%
range, the amount presumed necessary to reionize the universe. Analyzing a high-resolution
(4 pc) cosmological radiation-hydrodynamic simulation, we study how fesc changes
when we include two different products of binary stellar evolution—stars stripped
of their hydrogen envelopes and massive blue stragglers. Both produce significant
amounts of ionizing photons 10–200 Myr after each starburst. We find the relative
importance of these photons to be amplified with respect to escaped ionizing photons,
because peaks in star formation rates (SFRs) and fesc are often out of phase by
this 10–200 Myr. Additionally, low-mass, bursty galaxies emit Lyman continuum
radiation primarily from binary products when SFRs are low. Observations of these
galaxies by the James Webb Space Telescope could provide crucial information on
the evolution of binary stars as a function of redshift. Overall, including stripped
stars and massive blue stragglers increases our photon-weighted mean escape fraction
($\langle {f}_{\mathrm{esc}}\rangle $) by ∼13% and ∼10%, respectively, resulting
in $\langle {f}_{\mathrm{esc}}\rangle =17 \% $. Our results emphasize that using
updated stellar population synthesis models with binary stellar evolution provides
a more sound physical basis for stellar reionization.

text: 'Present and upcoming time-domain astronomy efforts, in part driven by gravitational-wave
follow-up campaigns, will unveil a variety of rare explosive transients in the
sky. Here, we focus on pulsational pair-instability evolution, which can result
in signatures that are observable with electromagnetic and gravitational waves.
We simulated grids of bare helium stars to characterize the resulting black hole
(BH) masses together with the ejecta composition, velocity, and thermal state.
We find that the stars do not react “elastically” to the thermonuclear ignition
in the core: there is not a one-to-one correspondence between pair-instability
driven ignition and mass ejections, which causes ambiguity as to what is an observable
pulse. In agreement with previous studies, we find that for initial helium core
masses of 37.5 M⊙ ≲ MHe, init ≲ 41 M⊙, corresponding to carbon-oxygen core masses
27.5 M⊙ ≲ MCO ≲ 30.1 M⊙, the explosions are not strong enough to affect the surface.
With increasing initial helium core mass, they become progressively stronger causing
first large radial expansion (41 M⊙ ≲ MHe, init ≲ 42 M⊙, corresponding to 30.1 M⊙ ≲ MCO ≲ 30.8 M⊙)
and, finally, also mass ejection episodes (for MHe, init ≳ 42 M⊙, or MCO ≳ 30.8 M⊙).
The lowest mass helium core to be fully disrupted in a pair-instability supernova
is MHe, init ≃ 80 M⊙, corresponding to MCO ≃ 55 M⊙. Models with MHe, init ≳ 200 M⊙
(MCO ≳ 114 M⊙) reach the photodisintegration regime, resulting in BHs with masses
of MBH ≳ 125 M⊙. Although this is currently considered unlikely, if BHs from these
models form via (weak) explosions, the previously-ejected material might be hit
by the blast wave and convert kinetic energy into observable electromagnetic radiation.
We characterize the hydrogen-free circumstellar material from the pulsational
pair-instability of helium cores by simply assuming that the ejecta maintain a
constant velocity after ejection. We find that our models produce helium-rich
ejecta with mass of 10−3 M⊙ ≲ MCSM ≲ 40 M⊙, the larger values corresponding to
the more massive progenitor stars. These ejecta are typically launched at a few
thousand km s−1 and reach distances of ∼1012 − 1015 cm before the core-collapse
of the star. The delays between mass ejection events and the final collapse span
a wide and mass-dependent range (from subhour to 104 years), and the shells ejected
can also collide with each other, powering supernova impostor events before the
final core-collapse. The range of properties we find suggests a possible connection
with (some) type Ibn supernovae.'
