text: "Motivation: Boolean networks are popular dynamical models of cellular processes
in systems biology. Their attractors model phenotypes that arise from the interplay
of key regulatory subcircuits. A succession diagram (SD) describes this interplay
in a discrete analog of Waddington’s epigenetic attractor landscape that allows
for fast identification of attractors and attractor control strategies. Efficient
computational tools for studying SDs are essential for the understanding of Boolean
attractor landscapes and connecting them to their biological functions.\r\nResults:
We present a new approach to SD construction for asynchronously updated Boolean
networks, implemented in the biologist’s Boolean attractor landscape mapper, biobalm.
We compare biobalm to similar tools and find a substantial performance increase
in SD construction, attractor identification, and attractor control. We perform
the most comprehensive comparative analysis to date of the SD structure in experimentally-validated
Boolean models of cell processes and random ensembles. We find that random models
(including critical Kauffman networks) have relatively small SDs, indicating simple
decision structures. In contrast, nonrandom models from the literature are enriched
in extremely large SDs, indicating an abundance of decision points and suggesting
the presence of complex Waddington landscapes in nature.\r\nAvailability and implementation:
The tool biobalm is available online at https://github.com/jcrozum/biobalm. Further
data, scripts for testing, analysis, and figure generation are available online
at https://github.com/jcrozum/biobalm-analysis and in the reproducibility artefact

text: Stars stripped of their hydrogen-rich envelopes through binary interaction
are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing
radiation observed in low-Z galaxies. A population of these stars was recently
observed for the first time, but their prevalence remains unknown. In preparation
for such measurements, we estimate the mass distribution of hot, stripped stars
using a population synthesis code that interpolates over detailed single and binary
stellar evolution tracks. We predict that for a constant star formation rate of
1 M⊙/yr and regardless of metallicity, a scalable model population contains ∼30
000 stripped stars with mass Mstrip > 1 M⊙ and ∼4000 stripped stars that are sufficiently
massive to explode (Mstrip > 2.6 M⊙). Below Mstrip = 5 M⊙, the distribution is
metallicity-independent and can be described by a power law with the exponent
α ∼ −2. At higher masses and lower metallicity (Z ≲ 0.002), the mass distribution
exhibits a drop. This originates from the prediction, frequently seen in evolutionary
models, that massive low-metallicity stars do not expand substantially until central
helium burning or later and therefore cannot form long-lived stripped stars. With
weaker line-driven winds at low metallicity, this suggests that neither binary
interaction nor wind mass loss can efficiently strip massive stars at low metallicity.
As a result, a “helium-star desert” emerges around Mstrip = 15 M⊙ at Z = 0.002,
covering an increasingly large mass range with decreasing metallicity. We note
that these high-mass stars are those that potentially boost a galaxy’s He+-ionizing
radiation and that participate in the formation of merging black holes. This “helium-star
desert” therefore merits further study.

text: In an n×n array filled with symbols, a transversal is a collection of entries
with distinct rows, columns and symbols. In this note we show that if no symbol
appears more than βn times, the array contains a transversal of size (1−β/4−o(1))n
. In particular, if the array is filled with n symbols, each appearing n times
(an equi- n square), we get transversals of size (3/4−o(1))n. Moreover, our
proof gives a deterministic algorithm with polynomial running time, that finds
these transversals.

text: Eigenstates of quantum many-body systems are often used to define phases of
matter in and out of equilibrium; however, experimentally accessing highly excited
eigenstates is a challenging task, calling for alternative strategies to dynamically
probe nonequilibrium phases. In this work, we characterize the dynamical properties
of a disordered spin chain, focusing on the spin-glass regime. Using tensor-network
simulations, we observe oscillatory behavior of local expectation values and bipartite
entanglement entropy. We explain these oscillations deep in the many-body localized
spin-glass regime via a simple theoretical model. From perturbation theory, we
predict the timescales up to which our analytical description is valid and confirm
it with numerical simulations. Finally, we study the correlation length dynamics,
which, after a long-time plateau, resume growing in line with renormalization
group (RG) expectations. Our work suggests that RG predictions can be quantitatively
tested against numerical simulations and experiments, potentially enabling microscopic
descriptions of dynamical phases in large systems.

text: The snow and glaciers of the Peruvian Andes provide vital water supplies in
a region facing water scarcity and substantial glacier change. However, there
remains a lack of understanding of snow processes and quantification of the contribution
of melt to runoff. Here we apply a distributed glacio-hydrological model over
the Rio Santa basin to disentangle the role of the cryosphere in the Andean water
cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous;
at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of
snowfall and melt. Due to the large catchment area affected by ephemeral snow,
its contribution to catchment inputs is substantial (23% and 38% in the wet and
dry season, respectively). Ice melt is crucial in the mid-dry season (up to 44%
of inputs). Our results improve estimates of water fluxes and call for further
process-based modelling across the Andes.

text: "We report the discovery of two new magnetic cataclysmic variables with brown
dwarf companions and long orbital periods (P_{\\rm orb}=95\\pm1 and 104\\pm2 min).
This discovery increases the sample of candidate magnetic period bouncers with
confirmed sub-stellar donors from four to six. We also find their X-ray luminosity
from archival XMM–Newton observations to be in the range L_{\\rm X}\\approx10^{28}-10^{29}
\\mathrm{erg\\,s^{-1}} in the 0.25–10 keV band. This low luminosity is comparable
with the other candidates, and at least an order of magnitude lower than the X-ray
luminosities typically measured in cataclysmic variables. The X-ray fluxes imply
mass transfer rates that are much lower than predicted by evolutionary models,
even if some of the discrepancy is due to the accretion energy being emitted in
other bands, such as via cyclotron emission at infrared wavelengths. Although
it is possible that some or all of these systems formed directly as binaries containing
a brown dwarf, it is likely that the donor used to be a low-mass star and that
the systems followed the evolutionary track for cataclysmic variables, evolving
past the period bounce. The donor in long period systems is expected to be a low-mass,
cold brown dwarf. This hypothesis is supported by near-infrared photometric observations
that constrain the donors in the two systems to be brown dwarfs cooler than \r\n1100 K
(spectral types T5 or later), most likely losing mass via Roche Lobe overflow
or winds. The serendipitous discovery of two magnetic period bouncers in the small
footprint of the XMM–Newton catalogue implies a large space density of these type
of systems, possibly compatible with the prediction of 40–70 per cent of magnetic
cataclysmic variables to be period bouncers."

text: "Context. The blue supergiant (BSG) domain contains a large variety of stars
whose past and future evolutionary paths are still highly uncertain. Since binary
interaction plays a crucial role in the fate of massive stars, investigating the
multiplicity among BSGs helps shed light on the fate of such objects.\r\nAims.
We aim to estimate the binary fraction of a large sample of BSGs in the Small
Magellanic Cloud (SMC) within the Binarity at LOw Metallicity (BLOeM) survey.
In total, we selected 262 targets with spectral types B0-B3 and luminosity classes
I-II.\r\n\r\nMethods. This work is based on spectroscopic data collected by the
FLAMES instrument, mounted on the Very Large Telescope, which gathered nine epochs
over three months. Our spectroscopic analysis for each target includes the individual
and peak-to-peak radial velocity measurements, an investigation of the line profile
variability, and a periodogram analysis to search for possible short- and long-period
binaries.\r\n\r\nResults. By applying a 20 km s−1 threshold on the peak-to-peak
radial velocities above which we would consider the star to be binary, the resulting
observed spectroscopic binary fraction for our BSG sample is 23 ± 3%. An independent
analysis of line profile variability reveals 11 (plus 5 candidates) double-lined
spectroscopic binaries and 32 (plus 41 candidates) single-lined spectroscopic
binaries. Based on these results, we estimated the overall observed binary fraction
in this sample to be 34 ± 3%, which is close to the computed intrinsic binary
fraction of 40 ± 4%. In addition, we derived reliable orbital periods for 41 spectroscopic
binaries and potential binary candidates, among which there are 17 eclipsing binaries,
including 20 SB1 and SB2 systems with periods of less than 10 days. We reported
a significant drop in the binary fraction of BSGs with spectral types later than
B2 and effective temperatures less than 18 kK, which could indicate the end of
the main sequence phase in this temperature regime. We found no metallicity dependence
in the binary fraction of BSGs, compared to existing spectroscopic surveys of
the Galaxy and Large Magellanic Cloud."

text: Given the uncertain evolutionary status of blue supergiant stars, their multiplicity
properties hold vital clues to better understand their origin and evolution. As
part of The Binarity at LOw Metallicity (BLOeM) campaign in the Small Magellanic
Cloud, we present a multi-epoch spectroscopic survey of 128 supergiant stars of
spectral type B5–F5, which roughly correspond to initial masses in the 6–30 M⊙
range. The observed binary fraction for the B5–9 supergiants is 25 ± 6% (10 ±
4%) and 5 ± 2% (0%) for the A–F stars, which were found using a radial-velocity
(RV) variability threshold of 5 km s−1 (10 km s−1) as a criterion for binarity.
Accounting for observational biases, we find an intrinsic multiplicity fraction
of less than 18% for the B5–9 stars and 8−7+9% for the AF stars, for the orbital
periods up to 103.5 days and mass ratios (q) in the 0.1 < q < 1 range. The large
stellar radii of these supergiant stars prevent short orbital periods, but we
demonstrate that this effect alone cannot explain our results. We assessed the
spectra and RV time series of the detected binary systems and find that only a
small fraction display convincing solutions. We conclude that the multiplicity
fractions are compromised by intrinsic stellar variability, such that the true
multiplicity fraction may be significantly smaller. Our main conclusions from
comparing the multiplicity properties of the B5–9- and AF-type supergiants to
that of their less evolved counterparts is that such stars cannot be explained
by a direct evolution from the main sequence. Furthermore, by comparing their
multiplicity properties to red supergiant stars, we conclude that the AF supergiant
stars are neither progenitors nor descendants of red supergiants.

text: 'Social dilemmas are collective-action problems where individual interests
are at odds with group interests. Such dilemmas occur frequently at all scales
of human interactions. When dealing with collective-action problems, people often
act reciprocally. They adjust their behavior to match the previous behavior of
the recipient. The literature distinguishes two kinds of reciprocity. According
to direct reciprocity, individuals react to their immediate experiences with the
recipient. They are more likely to cooperate if the recipient previously cooperated
with them. According to indirect reciprocity, individuals react to the recipient’s
general behavior, irrespectively of whether or not they benefited directly. In
practice, the two kinds of reciprocity are often intertwined; people typically
base their decisions on both direct experiences and indirect observations. Yet
only recently have researchers begun to explore how the two kinds of reciprocity
interact. So far, this research only addresses a single type of social dilemma,
the donation game, where the effects of individual behaviors are independent.
Instead, here we allow for all pairwise social dilemmas. By applying novel techniques
to generalize the theory of zero-determinant strategies, we establish an important
proof of principle: In all social dilemmas, socially optimal outcomes can be sustained
as an equilibrium, using either direct or indirect reciprocity, or arbitrary mixtures
thereof. These results neither require games to be repeated infinitely often,
nor that individual opinions are synchronized. In this way, we considerably generalize
the scope of models of reciprocity, and we build further bridges between the literatures
on direct and indirect reciprocity.'

text: "Context. Rapidly rotating classical OBe stars have been proposed as the products
of binary interactions, and the fraction of Be stars with compact companions implies
that at least some are. However, to constrain the interaction physics spinning
up the OBe stars, a large sample of homogeneously analyzed OBe stars with well-determined
binary characteristics and orbital parameters are required.\r\n\r\nAims. We investigated
the multiplicity properties of a sample of 18 Oe, 62 Be, and two Of?p stars observed
within the BLOeM survey in the Small Magellanic Cloud. We analyzed the first nine
epochs of spectroscopic observations obtained over approximately three months
in 2023.\r\n\r\nMethods. Radial velocities (RVs) of all stars were measured using
cross-correlation based on different sets of absorption and emission lines. Applying
commonly used binarity criteria, we classified objects as binaries, binary candidates,
and apparently single (RV stable) objects. We further inspected the spectra for
double-lined spectroscopic binaries and cross-matched with catalogs of X-ray sources
and photometric binaries.\r\n\r\nResults. We classify 14 OBe stars as binaries,
and an additional 11 as binary candidates. The two Of?p stars are apparently single.
We find two more objects that are most likely currently interacting binaries.
Without those, the observed binary fraction for the remaining OBe sample of 78
stars is fobs+candOBe = 0.18 ± 0.04 (fobs+candOBe = 0.32±0.05 including candidates).
This binary fraction is less than half of that measured for OB stars in BLOeM.
Combined with the lower fraction of SB2s, this suggests that OBe stars do indeed
have fundamentally different present-day binary properties than OB stars. We find
no evidence for OBe binaries with massive compact companions, in contrast to expectations
from binary population synthesis.\r\n\r\nConclusions. Our results support the
binary scenario as an important formation channel for OBe stars, as post-interaction
binaries may have been disrupted or the stripped companions of OBe stars are harder
to detect. Further observations are required to characterize the detected binaries,
their orbital parameters, and the nature of their companions."

text: "Context. The recently launched James Webb Space Telescope (JWST) is opening
new observing windows on the distant Universe. Among JWST’s instruments, the Mid
Infrared Instrument (MIRI) offers the unique capability of imaging observations
at wavelengths of λ > 5 μm. This enables unique access to the rest frame near-infrared
(NIR, λ ≥ 1 μm) emission from galaxies at redshifts of z > 4 and the visual (λ ≳ 5000
Å) rest frame for z > 9. We report here on the guaranteed time observations (GTO),
from the MIRI European Consortium, of the Hubble Ultra Deep Field (HUDF), forming
the MIRI Deep Imaging Survey (MIDIS), consisting of an on source integration time
of ∼41 hours in the MIRI/F560W (5.6 μm) filter. The F560W filter was selected
since it would produce the deepest data in terms of AB magnitudes in a given time.
To our knowledge, this constitutes the longest single filter exposure obtained
with JWST of an extragalactic field as of yet.\r\nAims. The HUDF is one of the
most observed extragalactic fields, with extensive multi-wavelength coverage,
where (before JWST) galaxies up to z ∼ 7 have been confirmed, and at z > 10 suggested,
from HST photometry. We aim to characterise the galaxy population in HUDF at 5.6
μm, enabling studies such as: the rest frame NIR morphologies for galaxies at
z ≲ 4.6, probing mature stellar populations and emission lines in z > 6 sources,
intrinsically red and dusty galaxies, and active galactic nuclei (AGNs) and their
host galaxies at intermediate redshifts.\r\n\r\nMethods. We reduced the MIRI data
using the official JWST pipeline, augmented by in-house custom scripts. We measured
the noise characteristics of the resulting image. Galaxy photometry was obtained,
and photometric redshifts were estimated for sources with available multi-wavelength
photometry (and compared to spectroscopic redshifts when available).\r\n\r\nResults.
Over the deepest part of our image, the 5σ point source limit is 28.65 mag AB
(12.6 nJy), ∼0.35 mag better than predicted by the JWST exposure time calculator.
We find ∼2500 sources, the overwhelming majority of which are distant galaxies,
but we note that spurious sources likely remain at faint magnitudes due to imperfect
cosmic ray rejection in the JWST pipeline. More than 500 galaxies with available
spectroscopic redshifts, up to z ≈ 11, have been identified, the majority of which
are at z < 6. More than 1000 galaxies have reliable photometric redshift estimates,
of which ∼25 are at 6 < z < 12. The point spread function in the F560W filter
has a full width at half maximum (FWHM) of ≈0.2″ (corresponding to 1.4 kpc at
z = 4), allowing the NIR rest frame morphologies and stellar mass distributions
to be resolved for z < 4.5. Moreover, > 100 objects with very red NIRCam vs MIRI
(3.6–5.6 μm > 1 mag) colours have been found, suggestive of dusty or old stellar
populations at high redshifts.\r\n\r\nConclusions. We conclude that MIDIS surpasses
preflight expectations and that deep MIRI imaging has great potential to characterise
the galaxy population from cosmic noon to dawn."

text: The Ca2+-release-activated Ca2+ (CRAC) channel Orai1 is activated by interaction
with the Ca2+ sensor Stromal Interaction Molecule 1 (STIM1). Owing to the lack
of structurally resolved Orai1/STIM1 complexes, the impact of their coupling on
individual Orai1 transmembrane domain (TM) movements is unclear. This study investigates
STIM1-independent and STIM1-dependent Orai1-TM dynamics using photocrosslinking
unnatural amino acids (UAAs) at each individual TM position. We primarily identify
CRAC-channel-like currents directly after UAA incorporation or additional UV-light
irradiation at TM3 sites that interface with non-pore-lining TMs. Using UAAs combined
with conventional site-directed mutagenesis and molecular dynamics simulations,
we discover that pore opening involves a widening of interfaces formed by TM3
with non-pore-lining TMs. Orai1 mutants with a UAA in TM3 exhibit weaker STIM1-induced
activation after UV exposure, possibly caused by a restricted widening of non-pore-lining
TM interfaces. We demonstrate that photocrosslinking UAAs are excellent tools
for improving our understanding of key determinants and ion channel dynamics modulating
pore opening.

text: Prussian blue (PB) and Prussian blue analogues (PBAs) are a class of porous
materials composed of transition metal cations, cyanide ligands, and alkali metal
cations. Their ability to intercalate and deintercalate ions within their framework
pores, coupled with the adaptability of their crystal structure to electrochemical
changes, underpins their success in battery applications. PBAs with Fe or Co as
the active site exhibit high redox potentials (vs SHE) and have been extensively
explored as cathode materials, with well-documented chemistry, crystal structures,
and electrochemical properties. In contrast, PBAs with Cr or Mn as the active
site display lower redox potentials and remain significantly underexplored as
anode materials. This gap has led to fewer reported compounds and a less comprehensive
understanding of their structural and electrochemical behavior, leaving the field
relatively opaque. In this perspective, we comprehensively analyze the challenges
involved in producing and employing PBAs with low redox potentials as active battery
materials. Conversely, we propose numerous horizons and ask fundamental questions
that should pave the way for future research to advance the field.

text: 'Binding precedents (súmulas vinculantes) constitute a juridical instrument
unique to the Brazilian legal system and whose objectives include the protection
of the Federal Supreme Court against repetitive demands. Studies of the effectiveness
of these instruments in decreasing the Court’s exposure to similar cases, however,
indicate that they tend to fail in such a direction, with some of the binding
precedents seemingly creating new demands. We empirically assess the legal impact
of five binding precedents, 11, 14, 17, 26, and 37, at the highest Court level
through their effects on the legal subjects they address. This analysis is only
possible through the comparison of the Court’s ruling about the precedents’ themes
before they are created, which means that these decisions should be detected through
techniques of Similar Case Retrieval, which we tackle from the angle of Case Classification.
The contributions of this article are therefore twofold: on the mathematical side,
we compare the use of different methods of Natural Language Processing — TF-IDF,
LSTM, Longformer, and regex — for Case Classification, whereas on the legal side,
we contrast the inefficiency of these binding precedents with a set of hypotheses
that may justify their repeated usage. We observe that the TF-IDF models performed
slightly better than LSTM and Longformer when compared through common metrics;
however, the deep learning models were able to detect certain important legal
events that TF-IDF missed. On the legal side, we argue that the reasons for binding
precedents to fail in responding to repetitive demand are heterogeneous and case-dependent,
making it impossible to single out a specific cause. We identify five main hypotheses,
which are found in different combinations in each of the precedents studied.'

text: "Technology involving hybrid superconductor–semiconductor materials is a promising
avenue for engineering quantum devices for information storage, manipulation,
and transmission. Proximity-induced superconducting correlations are an essential
part of such devices. While the proximity effect in the conduction band of common
semiconductors is well understood, its manifestation in confined hole gases, realized
for instance in germanium, is an active area of research. Lower-dimensional hole-based
systems, particularly in germanium, are emerging as an attractive platform for
a variety of solid-state quantum devices, due to their combination of efficient
spin and charge control and long coherence times. The recent experimental realization
of the proximity effect in germanium thus calls for a theoretical description
that is tailored to hole gases. In this work, we propose a simple model to describe
proximity-induced superconductivity in two-dimensional hole gases, incorporating
both the heavy-hole (HH) and light-hole (LH) bands. We start from the Luttinger–Kohn
model, introduce three parameters that characterize hopping across the superconductor–semiconductor
interface, and derive explicit intraband and interband effective pairing terms
for the HH and LH bands. Unlike previous approaches, our theory provides a quantitative
relationship between induced pairings and interface properties. Restricting our
general model to an experimentally relevant case where only the HH band crosses
the chemical potential, we predict the coexistence of \U0001D460-wave and \U0001D451-wave
singlet pairings, along with triplet-type pairings, and modified Zeeman and Rashba
spin–orbit couplings. Our results thus present a starting point for theoretical
modeling of quantum devices based on proximitized hole gases, fueling further
progress in quantum technology."

text: "The internal dynamical properties of red giant stars have been explored extensively
in recent\r\nyears as a result of the increase in high precision data availability
from the space missions\r\nKepler and TESS (Transiting Exoplanet Survey Satellite),
and in this exploration, it has been\r\ndiscovered that some of these stars are
not behaving as expected. Red giants are stars that have\r\nevolved off of the
main sequence after having completed fusing hydrogen into helium in their\r\ncore.
Observational data shows that the cores are rotating significantly slower than
models can\r\nrecreate consistently across evolutionary stages. This discrepancy
has prompted investigation\r\ninto the efficiency of angular momentum transport
mechanisms and mixing processes including\r\nmeridional circulation, shear instability,
internal gravity waves, Tayler-Spruit dynamo, fossil\r\nmagnetic fields etc.,
to explain this behavior.\r\nAnalyzing seismic oscillations in stars, via asteroseismology,
is a powerful tool as it is the only\r\nway in which the deep stellar interior
can be probed and subsequently characterized; this is\r\npossible as global oscillations
modulating the stellar surface are effected by internal processes.\r\nFor red
giants, p-modes (pressure modes; resonating through the entire star) and g-modes\r\n(gravity-modes;
resonating in the radiative interior) couple to create mixed modes. These\r\nmixed
modes give access to the otherwise hidden stellar interior as g-modes couple to
p-modes,\r\ndelivering information from the interior to the surface.\r\nInternal
magnetic signatures have been observationally confirmed in red giant stars via\r\nasteroseismology
and characterized in two ways. One being that dipole mixed modes with\r\nℓ = 1
will display a global asymmetric frequency shift of its azimuthal components;
where\r\nthe m = 0 and m = ±1 components of the ℓ = 1 dipole mode will be shifted
by two\r\ndifferent power laws, respectively. And the other being a reduced visibility
of dipole mixed\r\nmode amplitudes in the power spectra, where stars presenting
with this feature are denoted as\r\nsuppressed.\r\nSeveral studies of the suppressed
dipole mixed mode amplitudes have been carried out, but thus\r\nfar, no dedicated
studies of the asymmetric frequency shifts of suppressed red giants have been\r\nconducted;
one reason being that the asymmetric frequency shifts cannot be characterized\r\nwhen
the dipole mixed mode amplitudes are severely reduced in many of the suppressed
stars.\r\nSincefullysuppressedstarsdonothavedetectablemixed-modestoevaluate, partiallysuppressed\r\nstars,
that is, red giant stars presenting with suppressed dipole mixed modes in select
parts of\r\ntheir power spectra rather than across the entire spectra, will be
the subject of this study as\r\nthe respective mode amplitudes are still visible
at high frequencies.\r\nAs such, this study will search for asymmetric frequency
shifts on the dipole mixed\r\nmodes of partially suppressed red giant stars; the
aim here is to investigate if both\r\nmode suppression and magnetic shifting of
dipole mixed modes occur simultaneously.\r\nThisstudywillbeconductedbycreatingapipelinetoestimatepriorsofasteroseismicparameters,\r\nuse
the priors to model the power spectra with the stellar modeling code sloscillations_ISTA,\r\nand
perform a Bayesian fit of the parameters with the simulated data on the star KIC
6975038,\r\na target with partially suppressed dipolar mode amplitudes identified
in the literature, to fit its\r\nmagnetic parameters. I present a novel method
to model the stellar power spectra of\r\npartially suppressed red giants by application
of a sigmoid profile to the ℓ= 1 dipolar\r\nmode component of the spectra. With
the results of this study I aim at constraining\r\nthe cause of this partial dipole
mode amplitude suppression, allowing for more detailed\r\nstudies regarding their
astrophysical nature. Furthermore, the long term hope for the method\r\nused in
this study will be to expand the sample of partially suppressed red giants and
fit their\r\nasteroseismic parameters accordingly."

text: 'Asynchronous Boolean networks are a type of discrete dynamical system in
which each variable can take one of two states, and a single variable state is
updated in each time step according to pre-selected rules. Boolean networks are
popular in systems biology due to their ability to model long-term biological
phenotypes within a qualitative, predictive framework. Boolean networks model
phenotypes as attractors, which are closely linked to minimal trap spaces (inescapable
hypercubes in the system’s state space). In biological applications, attractors
and minimal trap spaces are typically in one-to-one correspondence. However, this
correspondence is not guaranteed: motif-avoidant attractors (MAAs) that lie outside
minimal trap spaces are possible. MAAs are rare and poorly understood, despite
recent efforts. In this contribution to the BMB & JMB Special Collection “Problems,
Progress and Perspectives in Mathematical and Computational Biology”, we summarize
the current state of knowledge regarding MAAs and present several novel observations
regarding their response to node deletion reductions and linear extensions of
edges. We conduct large-scale computational studies on an ensemble of 14 000 models
derived from published Boolean models of biological systems, and more than 100
million Random Boolean Networks. Our findings quantify the rarity of MAAs; in
particular, we only observed MAAs in biological models after applying standard
simplification methods, highlighting the role of network reduction in introducing
MAAs into the dynamics. We also show that MAAs are fragile to linear extensions:
in sparse networks, even a single linear node can disrupt virtually all MAAs.
Motivated by this observation, we improve the upper bound on the number of delays
needed to disrupt a motif-avoidant attractor.'

text: We present indirect constraints on the absolute escape fraction of ionizing
photons (f_{\rm esc}^{\rm LyC}) of the system GN 42912 which comprises two luminous
galaxies (M_{\rm UV} magnitudes of -20.89 and -20.37) at z\sim7.5, GN 42912-NE
and GN 42912-SW, to determine their contribution to the ionizing photon budget
of the Epoch of Reionization (EoR). The high-resolution James Webb Space Telescope
NIRSpec and NIRCam observations reveal the two galaxies are separated by only
~0.1" (0.5 kpc) on the sky and have a 358 km s^{-1} velocity separation. GN 42912-NE
and GN 42912-SW are relatively massive for this redshift (log(M_\ast/M_\odot)
\sim 8.4 and 8.9, respectively), with gas-phase metallicities of 18 per cent and
23 per cent solar, O_{32} ratios of 5.3 and >5.8, and \beta slopes of -1.92 and
-1.51, respectively. We use the Mg II\lambda\lambda2796,2803 doublet to constrain
f_{\rm esc}^{\rm LyC}. Mg II has an ionization potential close to that of neutral
hydrogen and, in the optically thin regime, can be used as an indirect tracer
of the LyC leakage. We establish realistic conservative upper limits on f_{\rm
esc}^{\rm LyC} of 8.5 per cent for GN 42912-NE and 14 per cent for GN 42912-SW.
These estimates align with f_{\rm esc}^{\rm LyC} trends observed with \beta, O_{32},
and the H\beta equivalent width at z<4. The small inferred ionized region sizes
(<0.3 pMpc) around both galaxies indicate they have not ionized a significant
fraction of the surrounding neutral gas. While these z>7 f_{\rm esc}^{\rm LyC}
constraints do not decisively determine a specific reionization model, they support
a minor contribution from these two relatively luminous galaxies to the EoR.

text: Unlike in crystals, it is difficult to trace emergent material properties
of amorphous solids to their underlying structure. Nevertheless, one can tune
features of a disordered spring network, ranging from bulk elastic constants to
specific allosteric responses, through highly precise alterations of the structure.
This has been understood through the notion of independent bond-level response—the
observation that, in many cases, different springs have different effects on different
properties. While this idea has motivated inverse design in numerous contexts,
it has not been formalized and quantified in a general context that not just informs
but enables and predicts inverse design. Here, we show how to quantify independent
response by linearizing the simultaneous change in multiple emergent features,
and introduce the much stronger notion of fully independent response. Remarkably,
we find that the mechanical properties of disordered solids are always fully independent
across a wide array of scenarios, regardless of the target features, tunable parameters,
system size, dimensionality, and class of interactions. Furthermore, our formulation
quantifies the susceptibility of features to parameter changes, which is correlated
with the maximum linear tunability. We also demonstrate the implications for multifeature
inverse design beyond the linear regime. These results formalize our understanding
of a key fundamental difference between ordered and disordered solids while also
creating a practical tool to both understand and perform inverse design.

text: Bacteria have evolved a wide range of defence strategies to protect themselves
against bacterial viruses (phages). Most known bacterial antiphage defence systems
target phages with DNA genomes, which raises the question of how bacteria defend
against phages with RNA genomes. Bacterial toxin–antitoxin systems that cleave
intracellular RNA could potentially protect bacteria against RNA phages, but this
has not been explored experimentally. In this study, we investigated the role
of a model toxin–antitoxin system, MazEF, in protecting Escherichia coli against
two RNA phage species. When challenged with these phages, the native presence
of mazEF moderately reduced population susceptibility and increased the survival
of individual E. coli cells. Genomic analysis further revealed an underrepresentation
of the MazF cleavage site in genomes of RNA phages infecting E. coli, indicating
selection against cleavage. These results show that, in addition to other physiological
roles, RNA-degrading toxin–antitoxin systems may also help defend against RNA
phages.
