  abstract     = {Evolutionary biology examines how the genetic and phenotypic composition
of populations changes over time. An important goal is to determine the
fixation probability of a single advantageous mutant that arises in a homogeneous
population of N residents. Many real populations experience environmental
gradients that cause mutations to be beneficial in some spatial
regions but harmful in others. Here, we study the fixation probability of a
mutant placed on a simple one-dimensional spatial structure that experiences
such a gradient. The mutant’s fitness varies linearly from1 − s to 1 + s, whereas
the resident fitness is constant and equal to 1. The existing literature suggests
that such heterogeneity in the mutant’s fitness should lead to a decrease in its
fixation probability. However, in this work, we find that small, non-negligible
gradients (s < 1=√N) substantially increase the fixation probability,while larger
gradients (s > (log N)/√N) substantially decrease it.Moreover, we quantify the
strength of this phenomenon analytically and we precisely delimit the range of
the gradients for which it occurs. Our computer simulations closely match
those findings. Altogether, our results indicate that subjecting a simple
population structure to natural environmental conditions can produce strong
counterintuitive effects.},

Existing approaches rely on deterministic state transfer, or probabilistic protocols that require active control or measurements and postselection. Here, we demonstrate a fundamentally different, fully autonomous process, where two remote qubits are entangled through their coupling to a quantum-correlated photonic reservoir. In our experiment, a Josephson parametric converter produces a Gaussian, continuous-variable entangled state of propagating microwave fields that drives two spatially separated superconducting transmon qubits into a stationary, discrete-variable entangled state. We also show how qubit tomography unlocks a direct and sensitive verification of two-mode squeezing in the microwave domain. These results establish networks of qubits interfaced with distributed continuous-variable entangled states as a powerful platform for foundational studies and quantum-technology applications.},

  abstract     = {When charge flows through a molecular circuit, it induces a magnetic field that allows the circuit to behave as a nanoscale electromagnet. However, in single-molecule circuits this magnetic field is usually weak. Here we show that radially π-conjugated carbon structures can support amplified circulating currents that generate local magnetic fields. Within tight-binding and density functional theory (DFT) frameworks, we first study cycloparaphenylene (CPP) junctions where both electrodes are attached to the same phenylene unit on the nanohoop. We observe an energy-dependent ring current component that traverses the whole macrocycle by mapping the local current density. Importantly, we find that destructive interference near degenerate resonances can reverse the ring current direction and amplify it strongly relative to the source–drain current. We show that this interference-driven design principle is general, and also carries over to C60 junctions. In fullerene, lower-lying degenerate resonances are more easily accessible through electrostatic gating, reaching a magnetic field of 14.2 mT under a 100 mV source–drain bias. This work thus provides new insights into ring currents in radially π-conjugated carbon structures and highlights their potential as design platforms for single-molecule electromagnets.},

  abstract     = {In the imprecise geometry model, the input is a family of regions F = (R₁, R₂, …,R_n), each containing a point p_i ∈ R_i. The task is then to compute some function of the points p₁,p₂,… p_n, in our case an implicit representation of their Pareto front. To this end, one may query a region R_i to retrieve its contained point p_i ∈ R_i. In this model, efficiency is interpreted in two ways: minimizing (i) the number of retrievals, and (ii) the computation time both for preprocessing, and the execution of the query stage, i.e. for computing which points to query and constructing the output. 
We present an algorithm to construct (an implicit representation of) the Pareto front for possibly overlapping rectangles, that is instance-optimal with respect to the number of retrievals. This means that for every fixed input (F, P), there is no algorithm that retrieves asymptotically fewer regions to compute the output. This is a strong algorithmic quality, as it means that our algorithm is competitive even to clairvoyant algorithms which only have to verify the correctness of a correct guess. In terms of algorithmic running time, instance-optimality is provably unobtainable. We instead present an algorithm which is within a log n-factor of instance optimality. This generalizes earlier results which assumed the regions to not overlap, at only a minor cost in running time. 
For unit squares, we present an algorithm that is not only instance optimal in the number of retrievals, but also universally optimal in terms of running time. This means that for any fixed set of regions F, no algorithm has a better worst-case running time for all possible point sets P. Thus, this work presents the first universally optimal algorithm for overlapping planar input. Compared to previous work, our result improves the degree to which the input regions may overlap, the preprocessing time, the number of retrievals, and the running time.},

benchmark for models of massive binary evolution and for the expected X-ray emission of Be+BH binaries. However, recent dynamical measurements cast doubt on the presence of a BH companion. We present new multi-epoch ultraviolet spectroscopy from the
Hubble Space Telescope, combined with high-resolution optical spectra, to reassess the nature of the companion. The far-ultraviolet
spectra reveal high-ionisation features – including prominent N v and He ii lines – which are absent in the spectra of normal Be stars
and are indicative of a hot, luminous companion. Spectral modelling shows that these features cannot originate from the Be star or
from an accretion disc around a compact object. Instead, we find that the data are best explained by a hot (Teff ≈ 85 kK), compact,
hydrogen-deficient star with strong wind signatures, consistent with an intermediate-mass stripped star. Our revised orbital solution
and composite spectroscopic modelling yield a companion mass of M2 = 1.48+0.55
−0.46 M, definitively ruling out a BH and disfavouring a
white dwarf. MWC 656 thus joins the growing class of Be + stripped star binaries. The system’s unusual properties – including a high
companion temperature and wind strength – extend the known parameter space of such binaries. The continued absence of confirmed
OBe+BH binaries in the Galaxy highlights a growing tension with population synthesis models.},

  abstract     = {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.},

  abstract     = {The massive binary common envelope (CE) phase plays a pivotal role in the formation of close black hole (BH)/neutron star binaries, yet significant uncertainties remain in our understanding of this process. In this study, we aim to constrain the massive binary CE phase by systematically reconstructing three observed BH X-ray binaries (BHXBs): GRO J1655-40, SAX J1819.3-2525, and 4U 1543-47. Through comprehensive binary evolution simulations and parametric supernova modeling, we establish lower limits for the CE efficiency parameters under different energy considerations within the standard energy formalism. Specifically, we derive minimum values for three cases: α0.5U and αU, representing CE efficiencies with half and all of the internal energy contributing to the envelope ejection, respectively, and αH, accounting for the envelope’s enthalpy. Our analysis reveals that the self-consistent formation of these three BHXBs requires CE efficiency parameters satisfying α0.5U ≳ 6.7, αU ≳ 4.2, and αH ≳ 1.7. Notably, we find no viable solutions with CE efficiency values below unity, even when considering the most extreme scenarios, in which the envelope binding energy is significantly reduced through enthalpy inclusion. Our results strongly imply that either additional energy sources are required or the formalism itself must be revised. Furthermore, we quantitatively assess the impact of BH natal kicks on our results. A key finding is that 4U 1543-47’s formation requires substantial natal kicks (≳50 km s−1), as lower kick velocities are incompatible with isolated binary evolution.},

U4atac homozygous mutants exhibit growth and neurodevelopmental defects, immunodeficiency, and gastrointestinal symptoms. Using bulk RNA-sequencing and functional assays, we reveal that mutations in U4atac affect the splicing of a large set of transcripts involved in innate immunity, hematopoiesis, and intestinal cell functions, including the Drosophila Janus kinase (JAK) homolog hopscotch (hop). Importantly, U4atac deficiency reduces Hop expression and causes Hop-related hematopoietic defects at the embryonic and larval stages. Notably, we also observe reduced expression of Jak1 and attenuated activation of downstream signaling in patients with Roifman syndrome.

  abstract     = {The element distinctness problem takes as input a list I of n values from a totally ordered universe, where pairwise comparisons between values are allowed, and the goal is to decide whether I contains any duplicates. It is a well-studied problem with a classical worst-case Ω(n log n) comparison-based lower bound by Fredman [TCS'76]. At first glance, this lower bound appears to rule out any algorithm more efficient than the naive approach of sorting I and comparing adjacent elements. However, upon closer inspection, the Ω(n log n) bound is overly pessimistic. For instance, if I contains n/2 identical elements, a median-finding algorithm will, regardless of the input order, find a duplicate in linear time. This raises a natural question: Are there comparison-based lower bounds for element distinctness that are sensitive to the amount of duplicates in the input instance?
To address this question, we derive instance-specific lower bounds. For any input instance I, we represent the combinatorial structure of the duplicates in I by an undirected graph G(I) that connects identical elements. Each such graph G is a union of cliques, and we study algorithms by their worst-case running time over all inputs I' with G(I') ≅ G. We establish an adversarial lower bound showing that, for any deterministic algorithm 𝒜, there exists a graph G and an algorithm 𝒜' that, for all inputs I with G(I) ≅ G, is a factor O(log log n) faster than 𝒜. Consequently, no deterministic algorithm can be o(log log n)-competitive for all graphs G. We complement this with an O(log log n)-competitive deterministic algorithm, thereby obtaining tight bounds for element distinctness that go beyond classical worst-case analysis. Subsequently, we study the related problem of set intersection. We show that no deterministic set intersection algorithm can be o(log n)-competitive, and provide an O(log n)-competitive deterministic algorithm. We find it interesting and surprising to discover tight O(log log n)-competitive bounds for element distinctness. Moreover, we find the separation between element distinctness and the set intersection problem unexpected.},

Here, we have outlined two labeling strategies. First, intraventricular injections in tadpoles transduce neural progenitor cells lining the ventricular system, resulting in cohort-based labeling of neurons as they differentiate during development. Second, direct intraparenchymal injections in post-metamorphic frogs enable spatially restricted labeling and anterograde or retrograde tracing of connectivity within defined brain regions. Together, these approaches provide selective access to developing and mature neural circuits in X. laevis, supporting applications ranging from anatomical tracing to functional imaging and manipulation of neural circuits.},

It employs fluorophore-tagged DNA hairpins that self-assemble on target-bound probe pairs, amplifying the signal without enzymatic reactions. Here, we describe a protocol for performing HCR fluorescence in situ hybridization (FISH) on Xenopus tissue sections. We also outline a semi-automated image analysis pipeline that enables per-cell quantification of probe expression and co-localization. This method provides a robust and quantitative approach for visualizing gene expression patterns in situ.},

  abstract     = {Auxin and calcium (Ca2+) are central plant signals that coordinate growth, development, and responses to environmental cues. Typically studied as largely parallel pathways, they are now increasingly recognized as interconnected networks whose activities converge at multiple regulatory levels. Recent advances in live imaging, biosensors, optogenetics, and structural approaches have revealed that auxin can rapidly trigger Ca2+ influx from the apoplast via TRANSPORT INHIBITOR RESPONSE1 (TIR1)/AUXIN-SIGNALING F-BOX (AFB)-dependent signaling mechanisms and Ca2+ channels, presumably involving cyclic nucleotides produced by TIR1/AFB auxin receptors. Conversely, Ca2+ signals arising from mechanosensing, wounding, and environmental stress can modulate auxin transport, signaling, and transcriptional outputs. Together, these discoveries highlight a dynamic, reciprocal signaling axis where Ca2+ acts both downstream and upstream of auxin to shape growth, development, tropisms, and regeneration.},

  abstract     = {We present the first truly subquadratic time algorithm to compute diameter and eccentricities in real-weighted directed graphs with constant distance VC-dimension and strongly sublinear-sized balanced separators. For real-weighted K_h-minor-free digraphs, this runs in O(n^{2-1/(2h-2)} polylog(n)) time.
Prior to this work, truly subquadratic time computation of diameter was only known for real-weighted planar graphs, while extensions to broader classes like minor-free graphs were restricted to unweighted settings. In particular, existing algorithms that use VC-dimension [Ducoffe, Habib, Viennot; SICOMP 2022] [Le, Wulff-Nilsen; SODA 2024] [Chan, Chang, Gao, Le, Kisfaludi-Bak, Zheng; FOCS 2025] work with small integer weights, but do not naturally generalize to real weights. We overcome this barrier by introducing a randomized search-to-decision reduction, demonstrating that VC-dimension is a sufficiently powerful tool in the real-weighted regime.},
