This paper proposes and numerically validates the Time Reversal Source Time Inversion (TRSTI) algorithm, which leverages the time-reversal symmetry of the wave equation to efficiently and accurately retrieve the source time function of small seismic events without the computational costs or empirical limitations of existing methods.
This study presents a rigorous analytical model for steady-state Stokes flow over lubricant-impregnated rectangular microtextures, revealing that lubricant fraction is the dominant factor in effective slip and that optimal lubricant viscosity depends on whether the design goal is maximizing drag reduction or enhancing anisotropic flow steering.
This paper enhances the Particle Geometry Space (PGS) framework by demonstrating that the particle circumdiameter, a key maximum dimension, can be accurately inferred from the y-axis intercept of the PGS plot, thereby enabling the direct estimation of maximum particle size from specific surface and volume without explicit length measurements.
This paper demonstrates that high-bandwidth analysis of force–distance curves in atomic force microscopy reveals hidden transient and Brownian-driven dynamics, enabling pixel-by-pixel mechanical contrast and time-resolved characterization of tip–sample interactions without external excitation or multi-pass imaging.
This paper introduces VAPOR, a variational quantum algorithm designed to implement Hamiltonian renormalization group flow on quantum computers to identify discretization-error-free operators and fixed points, demonstrated through a toy model in SU(2) Yang-Mills theory.
This paper presents a Boozer-coordinate energetic-particle trajectory tracker (BEPT) for axisymmetric tokamak equilibria that utilizes Hamiltonian guiding-center equations, Fourier-spline field interpolation, and a fourth-order Runge-Kutta integrator to achieve high accuracy in field reconstruction and conservation of kinetic energy and toroidal canonical momentum.
This methodological study derives a bias-variance decomposition for physics-anchored dephasing rate extrapolation and demonstrates through multi-seed synthetic experiments that while such anchoring robustly improves predictions for high-coherence devices, its benefits for low-coherence devices are statistically indistinguishable from zero, highlighting the critical importance of multi-seed evaluation and the risks of overgeneralizing single-run results.
This paper presents a hybrid differential quadrature method combined with the Crank–Nicolson scheme to numerically solve the (2+1)-dimensional generalized Benjamin–Bona–Mahony–Burgers equation, demonstrating its unconditional stability, convergence, and superior accuracy compared to existing methods through validation on five benchmark problems.
This study demonstrates that an Al/n-MoS2/p-Si heterojunction photodetector, fabricated using large-area vertically aligned CVD-grown MoS2 nanoflakes, exhibits enhanced UV-Vis photoresponse driven by efficient carrier injection, sharp-tip electron accumulation, and specific interface trap dynamics.
This paper evaluates the security of quantum distance-bounding protocols by isolating their fast phase and utilizing semidefinite programming to compute optimal one-round distance-fraud and mafia-fraud attack probabilities for discrete-variable systems, while also providing estimates for continuous-variable scenarios.
