Assessing fish diversity in the Amazon: The impact of primers and reference libraries in eDNA surveys

Abstract Selecting primers for DNA amplification poses a challenge in environmental DNA (eDNA) studies, particularly in biodiverse tropical ecosystems. Researchers must balance taxonomic coverage, primer specificity, and study feasibility when choosing between a single primer pai...

On the Order of Intersecting Hypergraphs

Abstract. Determining the maximum number of edges in an intersecting hypergraph on a fixed ground set under additional constraints is one of the central topics in extremal combinatorics. In contrast, there are few results on analogous problems concerning the maximum order of such...

UltrafastSwitchable Polar and Magnetic Orders byNonlinear Light–Matter Interaction

Abstract An outstanding challenge in materials science and physics is the harnessing of light for switching ferroic orders in, e.g., ferroelectrics. Here, we propose a mechanism through which electrons in few-layer 2D materials excited with above-bandgap light cause ionic structu...

Finite time blow-up and global solutions for the viscoelastic wave equation with combined power-type nonlinearities

The main objective of this paper is to investigate the global existence and nonexistence of solutions to the viscoelastic wave equation with a linear memory term of Boltzmann type, a nonlinear friction damping and a supercritical source term which is a combination of power-type n...

Methods of Selective Inference for Linear Mixed Models: A Review and Empirical Comparison

Summary Selective inference aims at providing valid inference after a data‐driven selection of models or hypotheses. It is essential to avoid overconfident results and replicability issues. While significant advances have been made in this area for standard regression models, rel...

Error Estimates of an Exponential Wave Integrator for the Nonlinear Schrödinger Equation with Singular Potential

Abstract. In this paper we analyze a first-order exponential wave integrator (EWI) for the nonlinear Schrödinger equation (NLSE) with a singular potential that is locally in [Formula: see text], which might be locally unbounded. A typical example is the inverse power potential su...

Assessing molecular, cellular and transcriptomic bases of laminar perfusion and cytoarchitecture coupling in the human cortex

Understanding how cellular architecture organizes cortical function requires mesoscopic approaches that resolve structure-function coupling in vivo. Here we introduce cerebral blood flow (CBF) and cell-body staining intensity (CSI) similarity index (CCSI), a localized similarity...

Reviving, reproducing, and revisiting Axelrod’s second tournament

Abstract Direct reciprocity, typically studied using the Iterated Prisoner’s Dilemma ( IPD ), is central to explaining cooperation. In the 1980s Robert Axelrod ran two computer tournaments in which Tit for Tat ( TFT ) emerged as the winner. Yet the archival record is incomplete:...

Detecting somatic mutations in rare clones using single-cell multiomics

Abstract Background Somatic mutations are increasingly recognised as drivers of diseases beyond cancer, including autoimmune disorders. However, identifying rare, cell type-specific causal mutations remains challenging due to their low frequency within heterogeneous cell populati...

Single-component self-assembling protein nanoparticles displaying stabilized prefusion-closed hemagglutinin trimers for influenza vaccine development

ABSTRACT Current influenza vaccines primarily target hemagglutinin (HA), the major surface glycoprotein and principal determinant of neutralizing antibody (NAb) responses. However, antigenic drift and shift, together with HA’s intrinsic metastability and low-pH sensitivity, pose...

Experimental investigation of the direct shear strength parameters of compacted snow

Abstract. Compacted snow is utilized as a building material in various construction and engineering applications across global high-latitude regions. For the safety assessment of snow and ice structures in cold regions, cohesion and internal friction angle are key shear strength...

Thermodynamic remnants in black-hole evaporation

Abstract We show that black-hole remnant scenario naturally arises in the original computations of Hawking without extra assumptions.

Evaluating urban heat adaptation strategies for extreme heatwaves in complex terrain: A case study of Grenoble, France

Urban heat adaptation strategies are critical for mitigating the impacts of ex- treme heat events in cities, particularly as climate change exacerbates their intensity and frequency. This study evaluates a set of adaptation strategies during the 2023 heatwave in Grenoble, France,...

DESI Strong Lens Foundry. IV. Spectroscopic Confirmation of DESI Lens Candidates with VLT/MUSE

Abstract We present integral field spectroscopic observations of 76 strong gravitational lens candidates identified with a residual neural network in the DESI Legacy Imaging Surveys, obtained with the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope. These o...

Unlocking innate computing abilities in electric grids

Electric power grids are engineered energy systems whose forward electrical responses embody high-dimensional and memory-bearing transformations of input signals. In this work, we reveal that these transformations-inherent in electric circuit elements, power flows and network top...

Geographies in flux - how time and location influence shrinking medium-sized cities

Urban shrinkage has emerged as a significant challenge across Europe, particularly for medium-sized cities (MSCs) with populations between 20,000 and 100,000. While previous research has largely focused on demographic decline in large cities, the spatial and institutional dynamic...

Xylose phosphatase activity of dystroglycan self-regulates its receptor function

Dystroglycan (DG), a transmembrane receptor crucial for tissue development and pathogen entry, harbors a glycan composed of xylose and glucuronic acid called matriglycan. Loss of matriglycan or reduction in its length affects DG function, causing dystroglycanopathies. However, th...

The Saxl hypergraph of a permutation group

Given a permutation group G ≤ Sym(Ω), a subset B of Ω is said to be a base if its pointwise stabiliser in G is trivial, and thebase size b(G) is the minimum size of a base. In the notable case b(G) = 2, Burness and Giudici define the Saxl graph of G to be the graph on Ω with base...

Killed path-dependent McKean-Vlasov SDEs for a probabilistic representation of non-conservative McKean PDEs

A McKean–Vlasov stochastic differential equation subject to killing associated to a regularised non-conservative and path-dependent nonlinear parabolic partial differential equation is studied. The existence and pathwise uniqueness of a strong solution and the regularity properti...
