Shear banding in simulations of polymer melts

Results from numerical simulations of polymers under shear flow are compared with predictions for shear banding based on a model coupling Rolie-Poly-like tube dynamics to the entanglement dynamics mediated by convected constraint release (CCR). CCR is controlled by a parameter β,...

Interfacial LithiumRedox Kinetics Regulated by SolventAsymmetry and Moment of Inertia in Li Metal Batteries

Abstract Lithium metal batteries (LMBs) offer high energy density, but interfacial charge-transfer kinetics remain a bottleneck for high-rate operation. In this work, we construct a library of 12 ether solvents with systematic variations in symmetry and fluorination, confirming t...

The Endomorphic Collapse Traverses the Foundations of Mathematics

This quiver's canonical bilinear form is provably dead: indefinite, selecting no Dynkin type at all. One bit, a sign on a single vertex, is the entire distance from that form to the Cartan matrix of su(3) ⊕ su(2). The forms deadness is what makes the gauge content live in the bit...

Theory of lineshapes in optical–optical double resonance spectroscopy

This paper presents a theory of lineshapes for molecular Optical-Optical Double Resonance (DR) Spectroscopy with arbitrary strength for both pump and probe fields using the steady-state solutions for the 3-level density matrix. When Doppler broadening can be neglected, the result...

Lateral Cyano Substitution as a Tool for Tuning Negative Dielectric Anisotropy in High‐Birefringence Liquid Crystals

A series of 10 novel liquid crystalline compounds based on oligophenyl and tolane cores bearing laterally positioned cyano groups has been designed, synthesized, and systematically investigated. The molecular architecture was tailored by varying the number and position of lateral...

An Energy-GradientStrategy for Triplet-Pair Separationin Singlet-Fission Oligomers

Abstract Singlet fission (SF) offers a pathway to surpass the Shockley–Queisser limit by converting one photoexcited singlet exciton into two triplet excitons. However, in molecular assemblies, this process commonly yields a strongly exchange-coupled correlated triplet pair, 1(TT...

Efficient Auxiliary-FieldQuantum Monte Carlo UsingIsometric Tensor Hypercontraction

Abstract Auxiliary Field Quantum Monte Carlo (AFQMC) has emerged as a powerful framework for treating strongly correlated electronic systems, offering a favorable balance between computational cost and accuracy. In this paper, we present a novel AFQMC method that uses the isometr...

Raman spectroscopic identification of biochemical alterations in Alzheimer’s disease brain tissue

<title>Abstract</title> Alzheimer’s disease (AD) is a progressive neurodegenerative disorder marked by chronic inflammation, neuronal loss, and continuous decline in memory and cognitive function. Raman Spectroscopy (RS) offers a powerful, label‑free approach for detecting early...

Data-Driven Modal Decomposition Analysis of Unsteady Flow in Multistage Turbine

Two data-driven modal analysis approaches, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), are applied to analyze the unsteady flow obtained by solving the Reynolds-averaged Navier–Stokes (RANS) equations in a 1.5-stage axial turbine. The reduced-order...

A note on gamma factors for pairs

Abstract In this short note we observe that the gamma factor defined by Gelfand and Kazhdan coincides with the Rankin-Selberg root number defined by Jacquet, Piatetskii-Shapiro and Shalika.

Enhancing Drone Light Shows Performances: Optimal Allocation and Trajectories for Swarm Drone Formations

ABSTRACT Drone light shows (DLShows) represent a rapidly growing application of swarm robotics, creating captivating aerial displays through the synchronized flight of hundreds or thousands of unmanned aerial vehicles (UAVs) as environmentally friendly and reusable alternatives t...

Clinical characteristics, etiologies, management, and outcomes of acute pancreatitis in Sub-Saharan Africa: a systematic review and meta-analysis

Abstract Background Acute pancreatitis (AP) is a leading cause of gastrointestinal-related emergency admissions globally. In Sub-Saharan Africa (SSA), the disease has historically been characterized as a benign surgical curiosity, yet contemporary reports suggest a transition tow...

Europe’s extreme temperatures and rainfall in finer detail: strengths and limits of climate model downscaling

<title>Abstract</title> Climate extremes in Europe are becoming increasingly frequent and severe, heightening the need for reliable regional climate information to support preparedness and adaptation. Downscaled climate model (DCM) products are widely used for this purpose. Yet,...

The effects of dietary iron supplementation on bacterial infections in Manduca sexta larval hemolymph

Abstract Iron is an essential nutrient for all types of organisms, including insects and the microbes that infect them. We predicted that insects fed an iron-supplemented diet would accumulate more iron in their hemolymph, and, because infectious microbes acquire iron from their...

High-need dental deserts in England: a national spatial analysis of NHS access and deprivation

<title>Abstract</title> Aim(s) The aim of this study was to identify high-need dental deserts in England and to quantify the population affected, describe the distribution of geographic access, and profile the demographic characteristics of this subgroup relative to other deserts...

ImmTACs overcome cytotoxic T cell suppression

Abstract Immune mobilizing monoclonal TCR against cancer (ImmTAC) are cancer therapeutics that activate T cells through recognition of a tumor-associated antigenic MHC/peptide complex. A first-in-class ImmTAC, Tebentafusp, is approved for the treatment of metastatic uveal melanom...

Dirichlet-type absorbing boundary conditions for ordinary state-based peridynamics

Reference implementation of Dirichlet-type absorbing boundary conditions for two-dimensional ordinary state-based peridynamic elastodynamics using the Linear Peridynamic Solid (LPS) model.

A live‐cell autophagy reporter reveals reversible vacuolation in naked mole‐rat skin fibroblasts under lysosomal stress

Abstract Naked mole-rats (NMRs, Heterocephalus glaber ) display unusual longevity and resistance to age-related decline, and accumulating evidence suggests that their autophagy–lysosome pathway (ALP) is regulated differently from that of conventional mammalian models. However, mo...

A Dynamic Mechanism for Prevalence of Triangles in Competitive Networks

Abstract Triangles are abundant in real-world networks but rare in standard null models for sparse graphs. Existing explanations typically rely on explicit triadic closure mechanisms or geometry-based connection rules. We propose an alternative hypothesis: the frequent appearance...
