The Evolution of Low-ionization Electron Densities in Galaxies across Cosmic Epochs

Abstract We investigate the low-ionization electron density in the interstellar medium (ISM) of galaxies across 0 < z < 8, derived with the [O ii ] λλ 3727, 3730 and [S ii ] λλ 6718, 6733 doublets, using both deep JWST/NIRCam/grism and NIRSpec/MSA spectroscopy. Along with ancilla...

Emergent coherent-incoherent phonon crossover enables ultralow lattice thermal conductivity in 3D double perovskite

The interplay between coherent (wave-like) and incoherent (particle-like) phonon transport is central to heat conduction, yet experimental evidence of their crossover in bulk three-dimensional (3D) crystals remains scarce. Here, we report intrinsically ultralow lattice thermal co...

Magnetic signatures in merger products

All template inlist files used to create the stellar models used in the 'Magnetic signatures in merger products' paper, as well as our additions to the 'run_star_extras.f90' file used to enable a nu_max-based stopping criterion. The single-star models were calculated based on the...

Is faster-X adaptation due to large-effect mutations? An empirical test of a new theory

Abstract A widespread observation in molecular evolution is that X-linked genes evolve faster—and often adapt faster—than autosomal genes. Three main ideas have been put forward to explain “faster-X” adaptation. The first is that new beneficial mutations are typically partially r...

Associations between urban form and urban multifunctionality: a comparative study

Abstract Cities are complex and dynamic systems that integrate social, ecological, and infrastructure domains. This study investigates and quantifies how urban forms are associated with multiple urban functions across these domains, and how these associations combine into positiv...

Monotonicity and decompositions of random regular graphs

In this work we establish several monotonicity and decomposition results in the framework of random regular graphs. Among other results, we show that, for a wide range of parameters d1≤d2, there exists a coupling of G(n,d1) and G(n,d2) satisfying that G(n,d1)⊆G(n,d2) with high pr...

A viral origin for RNA-guided immunity

Ancient viral warfare could be at the root of modern class 1 CRISPR bacterial defense systems

Multiple Argonaute complexes orchestrate epigenetic silencing in the Arabidopsis germline

Abstract Small RNAs (sRNAs) are widespread across diverse flowering plant species and play important roles regulating reproduction and environmental responses. However, how sRNAs exert their function is largely unknown, likely due to their typical origin in non-genic regions, the...

Redox-Driven Antiaromaticity Enables Multistate Conductance in 1D Topological Insulators

Abstract Conjugated molecules with diradical character have emerged as promising building blocks for high-conductance single-molecule electronics because of their behavior as 1D topological insulators. However, the impact of antiaromaticity on these radical-based edge states has...

Asymmetrical modulation of fear expression via GABA B receptors in the mouse medial habenula

Abstract The medial habenula (MHb) is implicated in regulating emotional responses to aversive events. Studies in zebrafish have identified a remarkable morphological left-right asymmetry in the dorsal habenula (zebrafish equivalent of mammalian MHb)-interpeduncular nucleus (IPN)...

Entangled States are Typically Incomparable

Abstract Consider a bipartite quantum system, where Alice and Bob jointly possess a pure state $$|\psi \rangle $$ | ψ ⟩ . Using local quantum operations on their respective subsystems, and unlimited classical communication, Alice and Bob may be able to transform $$|\psi \rangle $...

Topological dimension of the Gromov–Hausdorff and Gromov–Prokhorov spaces

The Gromov–Hausdorff distance is a dissimilarity metric capturing how far two spaces are from being isometric. The Gromov–Prokhorov distance is a similar notion for metric measure spaces. In this paper, we study the topological dimension of subspaces of the Gromov–Hausdorff and G...

Distortion of Multi-Winner Elections on the Line Metric: The Polar Comparison Rule

We study the problem of minimizing metric distortion in multi-winner elections, where a committee of size k is selected from a set of candidates based on voters’ ordinal preferences. We assume that voters and candidates are embedded on a line metric, and social cost is determined...

Bateman–Horn, polynomial Chowla and the Hasse principle with probability 1

Abstract With probability 1, we assess the average behaviour of various arithmetic functions at the values of degree 𝑑 polynomials f ∈ Z ⁢ [ t ] f\in\mathbb{Z}[t] that are ordered by height. This allows us to establish averaged versions of the Bateman–Horn conjecture, the polynom...

Little Red Dots host Black Hole Stars: A unified family of gas-reddened AGN revealed by JWST/NIRSpec spectroscopy

Abstract We construct and characterise a sample of 146 little red dots (LRDs) across 2.0 < z < 9.3, selecting all sources with v-shaped UV-optical continua from JWST NIRSpec/PRISM spectra and compact morphologies in NIRCam/F444W imaging. We show that LRD continuum spectra are wel...

pCORE, a set of open modular plasmids compatible with golden gate assembly

Abstract Modular DNA assembly based Golden Gate cloning (MoClo) is a widely used framework to assemble genetic constructs. A number of MoClo “destination vectors” have been developed, however, available options are still limited with regards to copy number and antibiotic resistan...

Circles of Confidence for Multi‐Label Geometry Completion

Abstract Inside–outside classification is widely used for geometry processing tasks such as surface reconstruction, geometry completion, and calculating signed distance fields. We introduce a new integral formulation of this problem, which assigns confidence scores that points ar...
