This study develops and validates a deterministic Pore Network Modeling framework to simulate particle clogging dynamics in porous media, revealing how particle size and conductance ratios influence permeability decline while identifying current limitations and proposing future enhancements for applications in groundwater remediation and filtration.
This study introduces a streamline-based local thermal non-equilibrium (LTNE) framework for subsurface heat transport that decouples fluid advection from multidimensional conduction and interphase exchange, demonstrating through benchmarks and heterogeneous simulations that significant local temperature differences between fluid and rock can persist even when macroscopic thermal responses appear near equilibrium.
This paper presents the first comprehensive framework for slowly rotating white dwarf models in f(R,Lm, T) = R + αLmT gravity, utilizing the Hartle-Thorne formalism to derive structure equations and numerically demonstrate that positive coupling constants increase the maximum mass beyond the Chandrasekhar limit while confirming the stability and calculating key rotational properties like moment of inertia and quadrupole moment.
This numerical study of natural convection around a heated cylinder in a square cavity reveals that the flow transitions from a steady state to chaos via the Ruelle-Takens-Newhouse route as the Rayleigh number increases from to , while establishing a specific power-law correlation for the cylinder's Nusselt number and highlighting the dominant role of the top wall in heat transfer due to thermal stratification.
This paper proposes that elementary particle spin is not an intrinsic property but a geometric "torsion residue" arising from the projection of discrete regular polyhedra onto continuous spheres, where local defects of 1/3 accumulate to a global residue of 1/12 that, when mapped to the imaginary unit, explains spin-precession coupling and the geometric renormalization origin of perpetual quantum motion.
This study theoretically and numerically demonstrates that Hermite-Gaussian structured light fields can optically modulate and confine ion-acoustic waves in plasmas, thereby altering their dispersion, frequency, and spatial profiles to enable new control mechanisms for plasmonic applications.
This study utilizes first-principles DFT calculations to demonstrate that cadmium alloying in cubic strontium titanate effectively modifies its electronic and optical properties by widening the bandgap and increasing the refractive index, thereby enhancing its potential for optoelectronic and photocatalytic applications.
This molecular dynamics study reveals that interfacial thermal conductance in graphene–C3B heterostructures is maximized at sharp interfaces and significantly suppressed by interfacial mixing due to enhanced phonon scattering and localized vibrational modes, while the heterostructure length has a relatively minor impact.
This paper demonstrates that generalized Bacon-Shor codes and quantum low-density parity-check constructions can surpass the fundamental hashing limit and, under certain conditions, the asymptotic quantum Singleton bound for quantum Pauli channels, particularly in low-rate schemes and biased noise environments.
The Simβ-AD study established a methodology for assessing radioactive waste activation at the CEMHTI Cyclotron by validating neutron fluence measurements from activation foils against four Monte-Carlo codes (FLUKA, MCNP6, PHITS, and RayXpert®), demonstrating good agreement between experimental data and simulations using simplified models.
