Integrating Information From Hydrologic Models and SWOT Remote Sensing Measurements to Estimate Discharge Across River Networks

Abstract The Surface Water and Ocean Topography (SWOT) satellite has the potential to improve knowledge of river discharge globally. However, SWOT discharge algorithms are informed by global hydrological model data, and a portion of the model's systematic bias is passed along to...

Isoperimetric and Geometric Inequalities in Quantitative Form: Stein’s Method Approach

Abstract. We adapt Stein’s method to isoperimetric and geometric inequalities. The main challenge is the treatment of boundary terms. We address this by using an elliptic PDE with an oblique boundary condition. We apply our geometric formulation of Stein’s method to obtain stabil...

Beyond the Analytic Solution Manufacturing for Anisotropic Elliptic Equations

Abstract. This article is aimed at introducing a new procedure for defining reference solutions to which the numerical approximations of anisotropic problems arising in plasma physics may be compared. In this context, the main issue is related to the construction of functions wit...

Divisorial Mori Contractions of Submaximal Length

A result due to Cho, Miyaoka, and Shepherd-Barron [in: Higher dimensional birational geometry (2002), 1–88] and Kebekus [in: Complex geometry (2002), 147–155] provides a numerical characterization of projective spaces. More recently, Dedieu and Höring [Algebr. Geom. 4 (2017), 120...

Synergistic Enhancement of Creep Performance in Al 19 Co 21 Fe 20 Ni 40 Eutectic High‐Entropy Alloy by Coupling Heterostructure Design With Boron‐Assisted Interfacial Optimization

ABSTRACT This study systematically investigates the creep behavior of an Al 19 Co 21 Fe 20 Ni 40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce...

Evidence for spin-fluctuation-mediated superconductivity in electron-doped cuprates

Abstract In conventional, phonon-mediated superconductors, the transition temperature and the linear-in-temperature normal-state scattering rate are linked through the electron–phonon coupling strength. In cuprate high-temperature superconductors, no equivalent relationship betwe...

SCREEN-LCA: Ex-ante prioritization of bio-based pathways for chemicals and plastics under a climate-mitigation objective

Life cycle assessment (LCA) is a key tool for guiding circular bioeconomy strategies, including the substitution of fossil carbon with bioresources. However, its data- and time-intensive nature can hinder its use when there are numerous candidate pathways, particularly in the che...

Wavelength-Selective Magneto-Optical Diodes Based on Rare-Earth Chiral Molecular Crystals

Abstract Chiral materials, integrating structural breaking of mirror-symmetry, exhibit physical properties that cannot be observed in centrosymmetric analogues. Among these properties, optical magneto-chiral anisotropy, the nonreciprocal absorption of light shown by chiral magnet...

Design and analysis of smooth geometry‐conforming lattices via Generalized Bézier patches

Abstract We propose a novel methodology to model globally G 1 geometry‐conforming metamaterials using Generalized Bézier‐based (GB) patches. Since every canonical tile is inscribed in a unit cube, we exploit its natural decomposition in octants and design multi‐sided patches for...

Scenario-Based Dynamic Assessment of Rooftop Solar Photovoltaic and Heat Pump Systems for Low-Emission French Single-Family Houses

Achieving the European Union’s (EU) climate neutrality targets requires residential buildings to reduce operational carbon emissions, while increasing on-site renewable generation. However, the relative contributions of rooftop photovoltaic (PV) systems with battery storage and h...

Integrated adipose tissue transcriptomic and miRNA remodeling identifies molecular pathways associated with residual cardiovascular risk after weight loss

Abstract Background Weight loss improves cardiometabolic health, yet substantial inter-individual variability remains in residual cardiovascular risk. Here, we investigated whether post-weight loss adipose tissue (AT) molecular remodeling is associated with this variability. Meth...

Gradient-enhanced global sensitivity analysis with Poincaré chaos expansions

Spectral methods, also known as chaos expansions, are widely used in global sensitivity analysis (GSA), as they leverage orthogonal bases of $L^2$ spaces to efficiently compute Sobol' indices, particularly in data-scarce settings. When derivatives of the model are available, a de...

Bridging the gap between genomic, phenotypic, and modeling data in picophytoplankton–virus interactions

Abstract We present a comprehensive synthesis of recent developments in methodological approaches to combine experimental and genomic studies of picophytoplankton–virus interactions. This synthesis will not only enhance our understanding of these relationships but also stimulate...

Swarming by curvature control in arbitrary dimension

We consider an interacting particle system proposed in the literature to model fish behavior. In this model, the agents move at constant speed and control the curvature of their trajectory (i.e. the time-derivative of their velocity) so as to align their velocity with that of the...

Trend to Equilibrium and Diffusion Limit for the Inertial Kuramoto–Sakaguchi Equation

Abstract. In this paper, we study the inertial Kuramoto–Sakaguchi equation for interacting oscillatory systems. On the one hand, we prove the convergence toward corresponding phase-homogeneous stationary states in weighted Lebesgue norm sense when the coupling strength is small e...

From human to urban metabolism: mapping flows of excreted nutrients based on current and prospective diets

Increasing awareness of the health, environmental, and geopolitical issues associated to mineral fertilizers have brought renewed attention to alternative sources of nutrients, such as those that flow from the sanitation systems of cities. This raises the questions: how much can...

Ground states on a fractured strip and one-dimensional reduction

We consider the nonlinear Schrödinger equation on a strip with Neumann boundary conditions and a delta condition at x = 0 . We first show the existence of ground states as minimizers of the action or of the energy under suitable constraints. We then prove that the energy minimize...

Stereoselective trans -1,4 Polymerization of Isoprene and β -Myrcene Mediated by Iron Complexes Bearing 1,1-Diaryl- N -(quinolin-8-yl)methanimine Ligands

Abstract Although iron has emerged as an earth-abundant alternative for 1,3-diene coordinative polymerization, stereoselective iron systems remain uncommon and are often associated with limited catalytic activity. Here, we report three iron(II) complexes supported by 1,1-diaryl-N...

Refinements on higher order Weil–Oesterlé bounds via a Serre type argument

Abstract Weil's theorem gives the most standard bound on the maximum number of points of a curve of genus over a finite field . This bound was improved by Ihara and Oesterlé for larger genus. A recent point of view allows one to recover these bounds by solving a sequence of semi‐...

Formal moduli problems and derived Lie algebras

We show that derived Lie algebras and restricted Lie algebras classify formal moduli problems on Artin divided power algebras and truncated algebras respectively. This article is part of the theme issue 'Derived Lie algebras in geometry and topology'.
