text: 'This preliminary study investigates the trace-element composition of ostracod
shells (Ostracoda: Crustacea) as biogenic calcium carbonates in their role as
environmental sentinels of pollution. Using high-resolution in-situ analysis,
we compared two contrasting coastal systems: the highly urbanized seascape of
metropolitan megacity Hong Kong (HKSAR) and the agriculturally dominated waters
of rural retreat Jeju Island, Republic of Korea (ROK). The goal was to assess
whether anthropogenic stress gradients affect trace element-to‑calcium ratios
(E/Ca) in the carapaces of shallow-marine Neonesidea Maddocks, 1969 species. Hereby,
the focus is laid on potential differences in the effects of extreme urbanization
and extreme agriculturalization. We analyzed 12 trace elements commonly incorporated
into ostracod shells using Inductively Coupled Plasma–Mass Spectrometry (ICP-MS).
Only Mn/Ca, Mg/Ca, and Ni/Ca ratios showed strong correlations with specific seawater
physicochemical parameters. Notably, Mn/Ca differed significantly between the
two sites, seemingly driven mainly by variations in nitrite nitrogen levels. This
suggests that Mn incorporation is sensitive to pollution source, urban versus
agricultural, though species-specific uptake effects cannot be excluded. No significant
differences in elemental uptake were found between adult and A-1 juvenile stages
of Neonesidea mutsuensis Ishizaki, 1961 or Neonesidea elegans (Brady, 1969), supporting
the use of both age groups in environmental reconstructions and increasing potential
sample yields. While remaining empirical and exploratory, our tentative findings
suggest that ostracod geochemistry holds promise for marine pollution monitoring
and cautiously supports the application of ostracod Mn/Ca ratios to reconstruct
anthropogenic, particularly nitrogen-related, impacts in nearshore environments
using sediment core records.'

text: "This note proves that only a linear number of holes in a Cech complex of
n points in R^d\r\ncan persist over an interval of constant length. Specifically,
for any fixed dimension p <\r\nd and fixed ε > 0, the number of p-dimensional
holes in the ˇ Cech complex at radius 1\r\nthat persist to radius 1+ε is bounded
above by a constant times n,where n is the number\r\nof points. The proof uses
a packing argument supported by relating theCˇ ech complexes\r\nwith corresponding
snap complexes over the cells in a partition of space. The argument\r\nis self-contained
and elementary, relying on geometric and combinatorial constructions\r\nrather
than on the existing theory of sparse approximations or interleavings. The bound\r\nalso
applies to Alpha complexes and Vietoris–Rips complexes. While our result can be\r\ninferred
from prior work on sparse filtrations, to our knowledge, no explicit statement\r\nor
direct proof of this bound appears in the literature."

text: Rational design strategies for self-assembly require a detailed understanding
of both the equilibrium state and the assembly kinetics. While the former is starting
to be well understood, the latter remains a major theoretical challenge, especially
in programmable systems and the so-called semi-addressable regime, where binding
is often nondeterministic and the formation of off-target structures negatively
influences the assembly. Here, we show that it is possible to simultaneously sculpt
the assembly outcome and the assembly kinetics through the underexplored design
space of binding energies and particle concentrations. By formulating the assembly
process as a complex reaction network, we calculate and optimize the tradeoff
between assembly speed and quality and show that parameter optimization can speed
up assembly by many orders of magnitude without lowering the yield of the target
structure. Although the exact speedup varies from design to design, we find the
largest speedups for nondeterministic systems where unoptimized assembly is the
slowest, sometimes even making them assemble faster than optimized, fully addressable
designs. Therefore, these results not only solve a key challenge in semi-addressable
self-assembly but further emphasize the utility of semi-addressability, where
designs have the potential to be faster as well as cheaper (fewer particle species)
and better (higher yield). More broadly, our results highlight the importance
of parameter optimization in programmable self-assembly and provide practical
tools for simultaneous optimization of kinetics and yield in a wide range of systems.

text: Meiotic drivers are selfish genetic elements that gain transmission advantages
by distorting equal, Mendelian segregation. For decades, biologists have considered
meiotic drivers as interesting, albeit esoteric, case studies. It is now clear,
however, that meiotic drive is more common and phylogenetically widespread than
previously supposed. Indeed, intensive study of a few well-known cases has begun
to reveal the evolutionary genomic consequences of meiotic drive. We argue here
that many features of genome evolution, content, and organization that are seemingly
inexplicable by organismal adaptation or nearly neutral processes are instead
best accounted for by recurrent histories of meiotic drive. We review how meiotic
drive can affect the evolution of sequences, gene copy numbers, genes with functions
in meiosis and gametogenesis, signatures of “selection,” chromosome rearrangements,
and karyotype evolution. We also explore the interactions of meiotic drive elements
with other classes of selfish genetic elements, including satellite DNAs, transposable
elements, and with the endogenous host genes involved in drive suppression. Finally,
we argue that some aspects of drive-mediated genome evolution are now sufficiently
well established that we might reverse the direction of discovery—rather than
ask how drive affects genome evolution, we can use genome data to discover new
putative drive elements.

text: Given a finite set of red and blue points in R^d, the MST-ratio is defined
as the total length of the Euclidean minimum spanning trees of the red points
and the blue points, divided by the length of the Euclidean minimum spanning tree
of their union. The MST-ratio has recently gained attention due to its direct
interpretation in topological models for studying point sets with applications
in spatial biology. The maximum MST-ratio of a point set is the maximum MST-ratio
over all proper colorings of its points by red and blue. We prove that finding
the maximum MST-ratio of a given point set is NP-hard when the dimension is part
of the input. Moreover, we present a quadratic-time 3-approximation algorithm
for this problem. As part of the proof, we show that in any metric space, the
maximum MST-ratio is smaller than 3. Furthermore, we study the average MST-ratio
over all colorings of a set of n points. We show that this average is always at
least n-2/n-1, and for n random points uniformly distributed in a d-dimensional
unit cube, the average tends to (math formular) in expectation as n approaches
infinity.

text: "To achieve fast recovery from link failures, most modern communication networks
feature fully\r\ndecentralized fast re-routing mechanisms. These re-routing mechanisms
rely on pre-installed static re-routing rules at the nodes (the routers), which
depend only on local failure information, namely on the failed links incident
to the node. Ideally, a network is perfectly resilient: the re-routing rules ensure
that packets are always successfully routed to their destinations as long as the
source and the destination are still physically connected in the underlying network
after the failures. Unfortunately, there are examples where achieving perfect
resilience is not possible. Surprisingly, only very little is known about the
algorithmic aspect of when and how perfect resilience can be achieved. We investigate
the computational complexity of analyzing such local fast re-routing mechanisms.
Our main result is a negative one: we show that even checking whether a given
set of static re-routing rules ensures perfect resilience is coNP-complete. Additionally,
we investigate other fundamental variations of the problem. In particular, we
show that our coNP-completeness proof also applies to scenarios where the re-routing
rules have specific patterns (known as skipping in the literature). On the positive
side, for scenarios where nodes do not have information about the link from which
a packet arrived (the so-called in-port), we present a linear-time algorithm to
realize perfect resilience whenever possible (which we show can also be determined
in linear time). "

text: "Runtime verification offers scalable solutions to improve the safety and
reliability of systems. However, systems that require verification or monitoring
by a third party to ensure compliance with a specification might contain sensitive
information, causing privacy concerns when usual runtime verification approaches
are used. Privacy is compromised if protected information about the system, or
sensitive data that is processed by the system, is revealed. In addition, revealing
the specification being monitored may undermine the essence of third-party verification.\r\n\r\nIn
this thesis, we propose a protocol for privacy-preserving runtime verification
of systems against formal sequential specifications. We develop the protocol in
two steps. In the first step, the monitor verifies whether the system satisfies
the specification without learning anything else, though both parties are aware
of the specification. In the second step, we extend the protocol to ensure that
the system remains oblivious to the monitored specification, while the monitor
learns only whether the system satisfies the specification and nothing more. Our
protocol adapts and improves existing techniques used in cryptography, and more
specifically, multi-party computation.\r\n\r\nThe sequential specification defines
the observation step of the monitor, whose granularity depends on the situation
(e.g., banks may be monitored on a daily basis). Our protocol exchanges a single

text: Antiferromagnets (AFMs) hold promise for applications in digital logic. However,
switching AFM domains is challenging, as magnetic fields do not couple to the
bulk antiferromagnetic order parameter. Here we show that magnetic-field-driven
switching of AFM domains can in many cases be enabled by a generic reduction of
magnetic exchange at surfaces. We use statistical mechanics and Monte Carlo simulations
to demonstrate that an inequivalence in magnetic exchange between top and bottom
surface moments, combined with the enhanced magnetic susceptibility of surface
spins, can enable deterministic selection of antiferromagnetic domains depending
on the magnetic-field ramping direction. We further show that this mechanism provides
a natural interpretation for experimental observations of hysteresis in magneto-optical
response of the van der Waals AFM $\mathrm{MnBi_2Te_4}$. Our findings highlight
the critical role of surface spins in responses of antiferromagnets to magnetic
fields. Furthermore, our results suggest that antiferromagnetic domain selection
via purely magnetic means may be a more common and experimentally accessible phenomenon
than previously assumed.

text: The population of the little red dots (LRDs) may represent a key phase of
supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging
as a key component to explain the most striking properties of LRDs, such as strong
Balmer breaks and Balmer absorption, as well as the weak IR emission. To dissect
the structure of LRDs, we analyzed new deep JWST/NIRSpec PRISM and G395H spectra
of FRESCO-GN-9771, one of the most luminous known LRDs at z = 5.5. These spectra
reveal a strong Balmer break, broad Balmer lines, and very narrow [O III] emission.
We revealed a forest of optical [Fe II] lines, which we argue are emerging from
a dense (nH = 109 − 10 cm−3) warm layer with electron temperature Te ≈ 7000 K.
The broad wings of Hα and Hβ have an exponential profile due to electron scattering
in this same layer. The high Hα : Hβ : Hγ flux ratio of ≈10.4 : 1 : 0.14 is an
indicator of collisional excitation and resonant scattering dominating the Balmer
line emission. A narrow Hγ component, unseen in the other two Balmer lines due
to outshining by the broad components, could trace the ISM of a normal host galaxy
with a star formation rate of ∼5 M⊙ yr−1. The warm layer is mostly opaque to Balmer
transitions, producing a characteristic P Cygni profile in the line centers suggesting
outflowing motions. This same layer is responsible for shaping the Balmer break.
The broadband spectrum can be reasonably matched by a simple photoionized slab
model that dominates the λ > 1500 Å continuum and a low-mass (∼108 M⊙) galaxy
that could explain the narrow [O III], with only a subdominant contribution to
the UV continuum. Our findings indicate that Balmer lines are not directly tracing
the gas kinematics near the SMBH and that the BH mass scale is likely much lower
than virial indicators suggest.

text: Galaxies exhibit a tight correlation between their star formation rate (SFR)
and stellar mass over a wide redshift range known as the star-forming main sequence
(SFMS). With JWST, the SFMS can now be investigated at high redshifts down to
masses of ∼106 M⊙, using sensitive star formation rate tracers such as the Hα
emission, which allow us to probe the variability in the star formation histories.
We present inferences of the SFMS based on 316 Hα-selected galaxies at z ∼ 4 − 5
with log(M★/M⊙) = 6.4 − 10.6. These galaxies were identified behind the Abell
2744 lensing cluster with NIRCam grism spectroscopy from the survey All the Little
Things (ALT). At face value, our data suggest a shallow slope in the SFMS (SFR ∝ M★α,
with α = 0.45). After we corrected this for the Hα-flux limited nature of our
survey using a Bayesian framework, the slope steepened to α = 0.59+0.10−0.09,
whereas current data on their own are inconclusive on the mass dependence of the
scatter. These slopes differ significantly from the slope of ∼1 that is expected
from the observed evolution of the galaxy stellar mass function and from simulations.
When we fixed the slope to α = 1, we found evidence for a decreasing intrinsic
scatter with stellar mass (from ∼0.5 dex at M★ = 108 M⊙ to 0.4 dex at M★ = 1010
M⊙). This difference might be explained by a (combination of) luminosity-dependent
SFR(Hα) calibration, a population of (mini)-quenched low-mass galaxies, or underestimated
dust attenuation in high-mass galaxies. Future deep observations with different
facilities can quantify these processes, which will enable us to achieve better
insights into the variability of the star formation histories.

text: Stellar wind mass loss of massive stars is often assumed to depend on their
metallicity Z. Therefore, evolutionary models predict that massive stars in lower-Z
environments are able to retain more of their hydrogen-rich layers and evolve
into brighter cool supergiants (cool SGs; Teff < 7 kK). Surprisingly, in galaxies
in the metallicity range 0.2 ≲ Z/Z⊙ ≲ 1.5, previous studies have not found a metallicity
dependence on the upper luminosity limit Lmax of cool SGs. Here, we add four galaxies
to the sample studied for this purpose with data from the Hubble Space Telescope
and the James Webb Space Telescope (JWST). Observations of the extremely metal-poor
dwarf galaxy I Zw 18 from JWST allow us to extend the studied metallicity range
down to Z/Z⊙ ≈ 1/40. For cool SGs in all studied galaxies, including I Zw 18,
we find a constant value of Lmax ≈ 105.6 L⊙, similar to literature results for
0.2 ≲ Z/Z⊙ ≲ 1.5. In I Zw 18 and the other studied galaxies, the presence of Wolf-Rayet
stars has been previously inferred. Although we cannot rule out that some of them
become intermediate-temperature objects, this paints a picture in which evolved
stars with L > 105.6 L⊙ burn helium as hot, helium-rich stars down to extremely
low metallicity. We argue that metallicity-independent late-phase mass loss would
be the most likely mechanism responsible for this. Regardless of the exact stripping
mechanism (winds or, for example, binary interaction), for the Early Universe
our results imply a limitation on black hole masses and a contribution of stars
born with M ≳ 30 M⊙ to its surprisingly strong nitrogen enrichment. We propose
a scenario in which single stars at low metallicity emit sufficiently hard ionizing
radiation to produce He II and C IV lines. In this scenario, late-phase metallicity-independent
mass loss produces hot, helium-rich stars. Due to the well-understood metallicity
dependence on the radiation-driven winds of hot stars, a window of opportunity
would open below 0.2 Z⊙, where self-stripped helium-rich stars can exist without
dense Wolf-Rayet winds that absorb hard ionizing radiation.

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: "1. Collective behaviours are a fascinating study area due to the emergent
properties that can only arise in groups of interacting individuals. However,
their quantitative study is often impaired by technical difficulties, creating
either low-quality and sparse data or impractical data amounts, particularly when
capturing large groups over long periods of time. Common challenges arise from
recording group members with as little obscuring of each other as possible, as
well as in generating manageable data amounts with as high as possible information
content.\r\n2. We here provide a multicomponent system that allows to record,
analyse and simulate the long-term spatiotemporal activity patterns of insect
collectives, especially ant colonies. Our Ant Observing System, ALTAA, comprises
a flat-nest design to prevent occlusion of individuals, a recording system running
on a low-power single-board-computer, and a set of computer programmes performing
quantitative analyses to guide the formation and validation of rules underlying
the observed collective patterns. Our system is scalable in that it allows parallel,
continuous observation of a high number of colonies using low memory space, with
colony maintenance requirements (e.g. feeding, nest humidity) being achieved at
lowest possible disturbance by the experimenter.\r\n3. We showcase the potential
of the system in a study using the black garden ant, Lasius niger, where we analyse
the spatiotemporal effects of different group sizes (1, 6, 10 ants), brood (larvae)
presence or absence, as well as of different nest geometries, over a period of
1 week. We show that the ants' motion activity has a weak periodicity in the range
of 20 to 120 min promoted by larval presence, and that ants are spatially attracted
to their larvae, the water source and the walls. We also find that the presence
of nestmates lowers an individual ant's motion activity. Observed data are compared
to simulations of the temporal activity of the ants.\r\n4. ALTAA provides a powerful
toolkit to quantify and interpret spatial and temporal collective activity patterns
in (social) insects over extended periods."

text: This study examines the distribution, growth, and GLOF hazard of glacial lakes
across major Himalayan river basins. Basin-wise GLOF susceptibility was assessed
using glacial lake abundance, spatial distribution, and rates of lake area expansion.
The Kosi, Yarlung Zangbo, Manas, and Upper Indus basins were identified as the
most susceptible and classified as critical. The highest rates of lake size increase
were observed in the Kosi Basin, followed by Yarlung Zangbo, Manas, Karnali, Upper
Indus, and Tista, indicating their potential as future GLOF-prone regions. Moreover,
a Himalayan-scale GLOF hazard map was generated integrating population, hydropower
infrastructure, potential flood volume, roads, settlements, and railways revealing
high hazard levels in the Chenab, Jhelum, Teesta, and Beas basins in India; the
Koshi, Tama-Koshi, and Dudh-Koshi basins in Nepal; and the Kuri Chu sub-basin
of the Manas Basin in Bhutan. These findings highlight priority regions where
detailed field investigations and hydrodynamic modelling are essential before
further infrastructure development.

text: Early embryo geometry is one of the most invariant species-specific traits,
yet its role in ensuring developmental reproducibility and robustness remains
underexplored. Here we show that in zebrafish, the geometry of the fertilized
egg—specifically its curvature and volume—serves as a critical initial condition
triggering a cascade of events that influence development. The embryo geometry
guides patterned asymmetric cell divisions in the blastoderm, generating radial
gradients of cell volume and nucleocytoplasmic ratio. These gradients generate
mitotic phase waves, with the nucleocytoplasmic ratio determining individual cell
cycle periods independently of other cells. We demonstrate that reducing cell
autonomy reshapes these waves, emphasizing the instructive role of geometry-derived
volume patterns in setting the intrinsic period of the cell cycle oscillator.
In addition to organizing cell cycles, early embryo geometry spatially patterns
zygotic genome activation at the midblastula transition, a key step in establishing
embryonic autonomy. Disrupting the embryo shape alters the zygotic genome activation
pattern and causes ectopic germ layer specification, underscoring the developmental
significance of geometry. Together, our findings reveal a symmetry-breaking function
of early embryo geometry in coordinating cell cycle and transcriptional patterning.

text: We demonstrate that periodically driven quantum rotors provide a promising
and broadly applicable platform to implement multigap topological phases, where
groups of bands can acquire topological invariants due to non-Abelian braiding
of band degeneracies. By adiabatically varying the periodic kicks to the rotor
we find nodal-line braiding, which causes sign flips of topological charges of
band nodes and can prevent them from annihilating, indicated by nonzero values
of the patch Euler class. In particular, we report on the emergence of an anomalous
Dirac string phase arising in the strongly driven regime, a truly out-of-equilibrium
phase of the quantum rotor. This phase emanates from braiding processes involving
all (quasienergy) gaps and manifests itself with edge states at zero angular momentum.
Our results reveal direct applications in state-of-the-art experiments of quantum
rotors, such as linear molecules driven by periodic far-off-resonant laser pulses
or artificial quantum rotors in optical lattices, whose extensive versatility
offers precise modification and observation of novel non-Abelian topological properties.
