Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration

Abstract We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and conceptually extendable to an arbitrary energy range. The electrons are produced via photoe...

RNA modular expression laboratory (RNAmel): an integrated R/Shiny platform for reproducible bulk RNA-seq analysis and interpretation

Abstract Background Bulk RNA-sequencing is routine, but turning a gene-level count matrix into biological insight still requires combining specialised tools for quality control, differential expression, dimensionality reduction, enrichment, co-expression networks, and activity in...

Turning Nd‐Fe‐B Swarf Into High‐Value Bulk Feedstocks via Sustainable Hydrogen Plasma: From Rare‐Earth Oxides to Metals and Hydrides

ABSTRACT Rare‐earth permanent magnets (REPMs) are crucial for electric vehicles, wind turbines, and other high‐efficiency electric motor systems. However, their production is energy‐intensive, and global recycling rates are below 0.2%. Machining swarf is the main industrial waste...

Efficient routing and spectrum allocation in arbitrary flex-grid entanglement networks

As practical quantum networks approach large-scale deployment, the need for efficient user-to-user frequency allocation is increasing, yet current approaches only provide partial solutions to the routing and spectrum allocation problem for an arbitrary quantum network. We address...

This dataset contains the raw physiological measurements, processed data, supplementary tables, and figure files supporting the manuscript entitled "Integrated Physiological Characterization and Multivariate Analysis Reveal Sulfate Salinity Tolerance in Upland Cotton (Gossypium h...

Evolution of binaries under stochastic perturbations

We develop a general Fokker-Planck framework describing the dynamical evolution of Keplerian binaries subjected to stochastic perturbations. The formalism provides an algorithmic way to obtain the Fokker-Planck drift and diffusion coefficients of any set of orbital variables give...

Lorentzian geometry of relaxation

We show that relativistic theories with purely relaxational excitation spectra, such as kinetic theory and transient hydrodynamics, naturally endow the dispersion plane $\{iω,ik\}$ with a Lorentzian geometric structure analogous to that of the Minkowski plane $\{t,x\}$. In this p...

Quantum Corrections as a Bound for Detecting Self-Interacting Ultralight Dark Matter

We investigate the implications of interactions between ultralight dark matter (ULDM) and Standard Model fermions for the radiative stability of the ULDM potential. By matching the heavy fermion onto a low-energy scalar effective field theory, we derive the one-loop threshold cor...

Accelerating droplet-laden Stokes flow simulations with hierarchical surrogate modeling

We present a surrogate modeling strategy for Stokes flows with liquid droplets suspended in a carrier fluid. Our approach is based on a multi-fidelity framework. At the lowest fidelity, droplets are treated as passive tracers, neglecting their influence on the ambient flow field....

Tunable Nonlinear Landscapes in Graphene Nanoelectromechanical Systems

Abstract Nonlinear nanomechanical resonators give convenient solid-state access to classical analogs of extreme nonlinear optics and to phononic signal processing. Here we report integer harmonic generation, phononic frequency sideband comb, and reverse period-doubling dynamics i...

A self-adaptive tube restraint for free-energy calculations along path collective variables

Path collective variables reduce a high-dimensional transition to a progress coordinate, s, and an orthogonal distance, z. Computing the free energy along s often requires restraining z, so that sampling embraces a tube centered on the reference path. However, a conventional fixe...

Neutron stars with an agnostic dark sector: Core and halo configurations from a two-fluid approach

The study of dark matter admixed neutron stars has the potential to advance our understanding of dark matter particle candidates. However, the large parameter space of dark matter particle masses restricts a systematic, model-independent study. In this analysis, we employ agnosti...

Hidden gauge freedom in complex-pole hierarchical equations of motion

While complex-pole hierarchical equations of motion (HEOM) have dramatically expanded the reach of numerically exact quantum dynamics simulations of open quantum systems, they suffer from numerical instabilities rooted in the non-Hermitian structure of their Liouvillian. Yet, the...

Control-Based Continuation for self-oscillating systems: Application to flow induced vibrations

An enhanced version of Control-Based Continuation (CBC) is proposed to carry out experimental continuation on self-sustained systems, whose working frequency is not known a priori. Our approach combines three main stages: an online frequency tracking algorithm using an embedded p...

Nonperturbative nonlinear Hall effect in nonequilibrium steady states

The nonlinear Hall effect in quantum materials has attracted broad interest, yet most existing studies focus on the weak-field, perturbative regime. Here we develop a nonperturbative approach based on nonequilibrium steady-state Green's functions for dc-field-driven lattice syste...

Precision solar system dynamics for ultralight dark matter search

Ultralight dark matter exhibits an order-one density fluctuation at the scale of its wavelength. This density fluctuation exists across the entire dark matter halo and interacts with stars and planets, perturbing their motion via gravitational interactions. We investigate the pos...

Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO 2 Electrolysis in Gas Diffusion Electrodes

ABSTRACT High‐rate electrolysis is commonly assessed using current density, single‐pass conversion and Faradaic efficiency, but these global metrics do not indicate whether the local reaction environment required for selective multicarbon formation is preserved during scale‐up. U...

Weak-coupling tensor cross interpolation impurity solver for nonequilibrium dynamical mean-field theory

Simulating nonequilibrium quantum many-body systems remains a major challenge due to the exponential growth of the computational complexity with real time. Here we implement a nonequilibrium impurity solver based on the weak-coupling expansion and the tensor cross interpolation (...

Trends in Methylidyne Radical Reactions at Temperatures Relevant to the Interstellar Medium

The methylidyne radical, CH, can react rapidly with an unusually broad range of molecules under temperatures relevant to cold molecular clouds, making CH an important driver of molecular complexity in the interstellar medium. This review focuses on reactions of CH with polyatomic...

Ecosystem service gradients at protected area borders reveal multiple patterns and prevalent management conflicts

Protected areas cannot halt biodiversity loss in isolation; integrating them with surrounding human-dominated landscapes is critical. However, this integration is challenged by substantial landscape heterogeneity at protected area borders, making it difficult to determine cross-b...
