In the 1970s, Tom Kurtz established foundational results on the rigorous approximation of continuous time Markov chains used in modeling chemical reaction networks. These results involved approximation of the stochastic processes over compact time intervals, and included functional laws of large numbers (hydrodynamic/f...

Advanced wound dressings should combine physical protection with localized and microenvironment-responsive delivery of therapeutic agents. Lycium barbarum glycopeptide (LbGp), a naturally derived macromolecular preparation with reported immunomodulatory and tissue-protective activities; however, its topical use is limi...

Abstract Thermal transit-time flowmeters are attractive for high-temperature, corrosive and irradiating environments, but the usual single-delay relation U = L/τ does not represent the effects of velocity-profile shear, radial scalar mixing, finite thermocouple response and channel mismatch. This study develops and tes...

Stochastic processes rooted in potential theory provide a rigorous mathematical language for quantifying healthcare access, measuring equity, and assessing systemic risk in complex environments. This chapter develops hitting probabilities and first-passage time theory within adaptive healthcare systems. Beginning with...

Urban traffic, environmental, and utility monitoring systems generate multivariate sensor streams whose spatial relations and missing-data mechanisms evolve over time. This critical narrative review examines graph-based forecasting and reconstruction in the presence of unreliable sensor observations. Foundational diffu...

The widespread application of agricultural films has resulted in the accumulation of microplastics (MPs) in soils, creating a coexistence with pesticides like atrazine. This study investigates the environmentally relevant interactions between field-aged polyethylene agricultural films (FAPE), virgin polyethylene (VPE),...

Abstract The Einstein Probe (EP) has discovered a fast X-ray transient, EP260321a, whose optical counterpart was subsequently classified as a broad-lined Type Ic supernova. Its observed rise time of about 690 s is inconsistent with theoretical predictions for shock breakout (SBO) from a Wolf–Rayet star, which is typica...

Inverse design of inorganic crystals, in which structures are generated to satisfy a target property while preserving diversity and physical plausibility, remains more demanding than ab initio generation, as property conditioning can degrade the structural quality that current generative models otherwise achieve. We pr...
Ultra-faint dwarf galaxies serve as powerful testing grounds for wave dark matter models through dynamical stellar heating. Previous simulation-based work derived a lower bound on the fuzzy dark matter particle mass using a diffusion approximation valid only when the de Broglie wavelength is much smaller than the galax...
Aluminum nanoparticles (ANPs) are among the most energy-dense solid fuels, yet the atomic mechanisms governing their transition from passivated particles to highly reactive states remain elusive. This stems from a fundamental computational bottleneck: Ab initio methods offer quantum-level fidelity but are restricted to...
