This paper analyzes all 960 Chess960 starting positions using Stockfish evaluations and a novel information-based metric to reveal a universal White first-move advantage and a highly heterogeneous landscape of strategic complexity and decision asymmetry, demonstrating that the classical chess setup is merely one configuration among many rather than a unique extremum.
This paper presents small-scale prototype testing and a novel, computationally-efficient control allocation algorithm for the CABLESSail concept, demonstrating its ability to effectively manage solar sail momentum through cable-actuated shape control while maintaining robustness against membrane shape uncertainties.
This paper presents a weakly nonlinear, multi-mode theory for Rayleigh-Taylor instability on a time-varying spherical interface, revealing that Bell-Plesset effects dramatically amplify growth and drive a powerful nonlinear selection rule that preferentially channels energy into axisymmetric modes.
This paper demonstrates that, unlike the classical cycloid solution for gravitational descent, the trajectory that minimizes ascent time for a cyclist with a fixed average power is a straight line with constant grade and speed, implying that steeper hills are optimal for maximizing climbing efficiency (VAM) within physical constraints.
This paper presents and validates a novel three-dimensional pulse shape simulation method for the reduced charge collection layer in p-type high-purity germanium detectors, implemented in the open-source package SolidStateDetectors.jl, to enable the identification and vetoing of critical surface background events in rare physics experiments.
This review synthesizes key concepts and theories of electrochemical electron transfer kinetics, emphasizing the integration of atomistic simulations like DFT and MD to characterize solvent dynamics and electronic coupling while critically evaluating the linear response approximation and outlining future directions for advanced multiscale quantum-classical modeling.
This paper presents electrical characterization results, specifically focusing on leakage current behavior and temperature dependence, for 8-inch silicon sensors irradiated with high-fluence neutrons up to $1.4 \times 10^{16}~n_{eq.}/cm^{2}$ to support the development of the CMS High-Granularity Calorimeter for the HL-LHC upgrade.
This paper presents simulation results demonstrating that an unseeded optical klystron free-electron laser, enhanced by a novel chicane-embedded optical delay scheme to mitigate slippage, can generate compact, sub-picosecond, multi-hundred-megawatt terahertz pulses at resonant wavelengths of 10, 30, and 100 μm.
This study utilizes validated particle-tracking simulations to demonstrate that optimizing electrospray thruster placement and utilizing deployable solar arrays can significantly mitigate plume impingement contamination on CubeSat solar arrays while maintaining high thrust efficiency across various spacecraft configurations.
This paper employs a global Vapor Kinetic Energy (VKE) budget analysis to reveal that atmospheric rivers evolve through consistent physical mechanisms worldwide, primarily intensifying via potential-to-kinetic energy conversion and decaying through condensation and turbulent dissipation, thereby establishing the VKE framework as a powerful diagnostic tool for understanding AR dynamics and regional variability.
This paper presents an energy-core-based photon reconstruction method utilizing the Hough transform, which achieves near-perfect efficiency and separation for high-energy photons in dense environments, as validated by simulations of the CEPC crystal electromagnetic calorimeter.
MACE4IRmol is an uncertainty-aware foundation model ensemble trained on ~16 million diverse molecular geometries that enables rapid, accurate, and reliable prediction of infrared spectra and related properties across broad chemical space at a fraction of the computational cost of density-functional theory.
This paper presents a method using Dirac's theory of constraints to systematically enforce quasineutrality and charge density conservation in electrostatic plasma models (Vlasov-Poisson and Vlasov-Ampère) by constructing generalized Dirac brackets that eliminate the electric field and introduce specific advection terms, thereby enabling a rigorous assessment of the quasineutral approximation's validity across kinetic scales.
This study utilizes ERA5 data and CESM1.2 simulations enhanced by a rare events algorithm to demonstrate that persistent double jet states over Eurasia are dynamically linked to positive Northern Annular Mode and quasi-wave-3 patterns, which collectively drive extreme heatwaves across three specific centers in the Northern Hemisphere.
This study combines theoretical analysis and numerical simulations to demonstrate that a stationary triangular strain field induces resonant instability in a Batchelor vortex, where the introduction of axial flow reduces critical layer damping to activate additional unstable mode pairs and ultimately shifts the dominant instability from a specific mode combination to one involving the first branches of both azimuthal wavenumbers.
This paper presents a model of a spring-connected crawler using tabular Q-learning to demonstrate that while centralized control offers superior speed and robustness by leveraging long-range correlations, intermediate hierarchical architectures provide an optimal trade-off between performance and computational cost compared to purely distributed or fully centralized approaches.
This paper extends the Theory of Porous Media to model non-isothermal material injection into porous structures, specifically for percutaneous vertebroplasty, by incorporating local thermal non-equilibrium conditions and demonstrating thermodynamic consistency through numerical simulations.
This study presents the first fully kinetic simulations demonstrating that self-excited wave-wave and wave-particle interactions in a warm plasma can rapidly diffuse runaway electrons backward, reducing their current by nearly half on timescales far shorter than experimental shot durations.
This paper expounds on and extends cognitive scientist Donald Hoffman's argument that human perception is an evolutionary interface for fitness rather than reality, by integrating key concepts from modern physics such as black holes, the holographic principle, string theory, duality, quantum gravity, and special relativity to support his view.
This paper presents a systematic asymptotic reduction of the Poisson–Nernst–Planck–Stokes equations for narrow channels that remains valid even when the Debye length is comparable to the channel width, enabling the prediction of complex ion transport phenomena such as counter-gradient ion flow and enhanced selectivity due to finite-size effects.
