Testing the strong equivalence principle with multimessenger binary neutron star mergers

Abstract The constancy of the gravitational constant G is a cornerstone of the strong equivalence principle and of general relativity, yet its possible temporal variation remains a key target in tests of fundamental physics. Gravitational-wave (GW) astronomy, especially when comb...

Discussion on Decompression Path and Wave Speed of Supercritical and Dense CO2 with Impurities

Decompression of dense and supercritical CO2 containing impurities was investigated using an equilibrium isentropic model coupled with NIST REFPROP 10 and GERG-2008. The pressure plateau was determined from the intersection of the isentropic path and the bubble line. The adopted...

Facilitation of explosive bursts’ prevention in reversed magnetic shear tokamak plasmas through the current condensation effect for disruption avoidance

The reversed magnetic shear (RMS) configuration, a promising candidate for steady-state tokamak operation, facilitates high bootstrap current fractions through internal transport barriers, but also hosts multiple rational surfaces vulnerable to tearing modes. Under high bootstrap...

Rapid prediction of full-field stress evolution during drilling of carbon fiber reinforced polymer: A finite element database-driven graph recurrent surrogate model

Stress evolution during carbon fiber reinforced polymer (CFRP) drilling governs drilling-induced damage and strongly affects hole quality and the structural reliability of aerospace components. Rapid and accurate prediction of stress-field evolution is essential for online proces...

Semi-conjugacy rigidity for endomorphisms derived from Anosov on the 2-torus

Abstract Let f be a non-invertible partially hyperbolic endomorphism on T 2 $\mathbb {T}^2$ double struck upper T squared that is derived from a non-expanding Anosov endomorphism. Differing from the case of diffeomorphisms derived from Anosov automorphisms, there is no a priori s...

Method for improving robotic surface milling accuracy by stiffness optimization and force-induced error compensation

Purpose In robotic surface milling, the inherently low stiffness of industrial robots often leads to significant force-induced deformation errors and reduced machining accuracy. This study aims to propose a multi-factor optimization method that combines stiffness optimization wit...

The impact of inhibitory control and working memory capacity on verbal-humor processing: an ERP investigation

Abstract Verbal-humor processing is a sophisticated cognitive-emotional task. While domain-general executive functions like inhibitory control (IC) and working memory capacity (WMC) are known to influence language comprehension, their specific, stage-dependent contributions to th...

Nonalternating Chain Walking Polymerization Enables In-Chain Ketone Polyolefin Elastomers

Abstract Millions of tons of polymer waste are generated annually from branched polyethylene-based single-use packaging and agricultural films, constituting a pressing global environmental concern. Nonalternating carbonylative chain walking polymerization offers a promising strat...

Template Curvature-Induced Tensile Strain Optimizes the Oxygen Evolution Reaction Activity of α-Co(OH)2

Abstract The high energy barriers of the oxygen evolution reaction (OER) are the main bottleneck in electrocatalytic water splitting, and developing efficient nonprecious metal catalysts is crucial. Here, we report a novel and controllable curvature-induced strain engineering str...

Structural Modification of Bifenox Derivatives: Discovery of Novel Diaryl Thioethers as Potent Insect Trehalase Inhibitors

Abstract To discover novel noncarbohydrate trehalase inhibitors, 62 bifenox derivatives were designed and synthesized in this study. Among them, diaryl thioether 2b-1 exhibited optimal trehalase inhibitory activity with 72.5% inhibition rate at 100 μM and a Ki value of 36.3 μM, s...

Global bounded solutions of the 3D Patlak-Keller-Segel-Navier-Stokes system via Couette flow and logistic source

As is well-known, the solutions to the Patlak-Keller-Segel system in 3D may blow up in finite time regardless of any initial cell mass. In this paper, we investigate the existence of global bounded solutions of the 3D Patlak-Keller-Segel-Navier-Stokes system with a large initial...

A Time-Aware BiLSTM-PSO-SVR Framework for Predicting the Hysteretic Response of Circular Steel Tube Braces

Steel braces in concentrically braced frames exhibit nonlinear axial force–displacement responses under repeated tension and compression. This study develops a workflow for predicting the hysteretic response of pin-ended circular steel tube braces. A distributed-plasticity OpenSe...

Knowledge Distillation TabPFN for Predicting Dismantled Material Weight of Retired Oil-Immersed Transformers

The dismantled components of retired oil-immersed power transformers, particularly the windings and core, have high recycling economic value. However, accurately estimating their weight based solely on nameplate information prior to disassembly remains a key challenge for recycli...

Visual snow syndrome as a neuropsychiatric network disorder: clinical features, mechanisms, and therapeutic perspectives

Abstract Visual Snow Syndrome (VSS) is a neurological condition characterized by the persistent perception of dynamic, flickering, dot-like visual disturbances across the entire visual field, resembling television static. Increasing evidence indicates that VSS is frequently accom...

Periodic Solute Segregation Weakens Chemically Stabilized Grain Boundaries

Abstract Solute segregation can chemically stabilize grain boundaries (GBs), but whether such interfaces remain mechanically robust under load remains unclear. Here, atomic-resolution HAADF-STEM and atomistic modeling identify a periodically Nd-decorated asymmetric [12̅10] tilt G...
