We investigate the dynamics and stability of three immiscible viscous liquid layers coating the interior of a vertical cylindrical tube, a configuration relevant to stratified core--annular transport processes. A long-wave asymptotic analysis yields a coupled system of nonlinear evolution equations governing the motio…
The optical modes of mesoscale plasmonic waveguides (MPWs) are significantly affected by nonclassical quantum effects, which can be comprehensively described by the nonclassical electromagnetic boundary condition (NEBC) formulated with the surface-response Feibelman d-parameters. In this paper, a perturbation theory f…
Alternative divertor configurations (ADCs) must be evaluated under boundary plasma conditions approaching reactor-level values to be considered a reliable, physics-based solution for tokamak power exhaust. Most ADC experiments performed to date were at relatively low exhaust power. This work presents a high-power scen…
Many benchmarks track Large Language Model (LLM) performance on tasks with verifiable answers, but less is known about how LLM performance is evolving on open-ended tasks, where creativity, originality and diversity may matter as much as quality. As LLMs increasingly support human ideation and creative work, understan…
Most modern optimizers form their momentum as an exponential moving average (EMA) of past gradients, forgetting every direction at one fixed rate. However, the inputs a deep network sees during training can be highly anisotropic, with a few directions queried frequently while most are seen rarely. Recent methods addre…
Subgap bound states can produce pronounced features in the density of states without necessarily giving rise to a corresponding signal in ultrasonic attenuation. We show that the coherence factors act as a filter for the contribution of bound states to ultrasonic attenuation. In a phase-biased superconductor--normal--…
A reliable power supply system is a fundamental requirement for unmanned offshore gas platforms because instrumentation, control, communication, and safety systems must operate continuously. Most studies on Photovoltaic–Thermoelectric Generator (PV–TEG) systems have focused on component optimization or laboratory-scal…
We study a long-range perturbation of the perimeter functional by a nonlocal repulsive term defined through the Yukawa kernel, minimized under a volume constraint. Because the kernel decays exponentially, the competition between surface tension and repulsion is governed by two independent quantities, the screening rat…
Weak particle-matrix interfaces play a critical role in the tensile fracture of particle-filled polymer composites, but how they govern progressive debonding, fracture localization, and the resulting changes in macroscopic mechanical properties remains insufficiently understood. In this study, a cohesive-zone phase-fi…
Lithium niobate and lithium tantalate see widespread use in optics and electronics, and are increasingly used for cryogenic applications. Despite their broad deployment, their optical band gap and its relation to the crystal stoichiometry are not well characterised as a function of temperature. In this work, we study…
Electron phonon coupling governs charge transport, carrier relaxation, and polaron formation in halide perovskites, yet its microscopic origin in low dimensional systems remains poorly understood. Here, we combine operando, bias dependent Raman spectroscopy with density functional theory (DFT) calculations to directly…
Quantitative microstructural characterization of Li-ion battery electrode materials using electron backscatter diffraction (EBSD) has been proven as a critical method for optimizing cell performance. However, the inherently slow nature of EBSD can hinder the throughput of analyses needed for statistical representation…
We study quantum transport through a magnetic barrier in a nodal-line semimetal. When the Fermi energy lies near the nodal ring, the Fermi surface has toroidal geometry. Each cross-section in a plane parallel to the nodal ring consists of two concentric contours, inner and outer, carrying distinct transport channels.…
Clifford circuits play a foundational role in quantum computing, particularly due to their importance in quantum error correction and fault-tolerant logical synthesis. While these circuits can be efficiently simulated and represented as symplectic matrices, standard synthesis methods-such as the Aaronson-Gottesman alg…
Anti-altermagnets exhibit odd-parity nonrelativistic spin splitting, yet unlike even-parity altermagnets, their momentum-space symmetries lack a reduced classification analogous to spin Laue groups. Here, we introduce anti-spin Laue groups, organized into three distinct classes, and identify 21 groups describing the o…
Abstract Arsenic can concentrate in phosphate minerals, such as apatite, with levels exceeding whole-rock concentrations in some felsic igneous suites. This strong As-apatite association is ascribed to oxidizing conditions during crystallization, as arsenate [AsVO43-] is expected to be more compatible than arsenite [A…
High-pressure hydrides hold the record for the highest superconducting critical temperatures across all classes of superconductors. Currently lanthanum decahydride, LaH$_{10}$, exhibits the highest critical temperature among binaries, with $T_c \approx$ 250 K at pressures between 140-180 GPa. Here, we report the synth…
This study explores the mechanisms of intrusive growth in secondary xylem fibers, a process determining their length and future mechanical performance. The flax variety CDC Bethune and the derived from it rdf mutant with reduced fiber length were analyzed to identify factors influencing intrusive growth. The structure…
This paper focuses on a theoretical examination of a double magnetic superconducting quantum well made from a hybrid InAs/AlSb heterostructure with an aluminum superconducting layer in order to understand Majorana bound states in semiconductor-superconductor hybrid systems. Through the superconducting proximity effect…
Capillary hysteresis is a pore-scale phenomena that has considerable influence on oil displacement, residual oil trapping, phase connectivity, and efficiency of oil recovery in porous media. Although enhanced oil recovery (EOR) techniques are often evaluated based on their effectiveness in interfacial tension reductio…
