Seasonal variation of diurnal rainfall characteristics over Vietnam.

This study explores the characteristics and mechanisms of diurnal rainfall in Vietnam (VN), focusing on two key aspects: (1) the ability of Integrated Multi-satelliteE Retrievals for GPM (IMERG) to capture regional and seasonal sub-daily rainfall patterns; (2) the influence of multi-scale atmospheric processes in shaping these patterns. Data from 171 rain gauge stations served as a reference for the evaluation. Results indicate that while IMERG underestimates the magnitude of diurnal rainfall variation, it successfully identifies regional and seasonal differences in diurnal rainfall timing.

Nonequilibrium phase diagram for the serration statistics during slow deformation of refractory high-entropy alloys.

Diverse slip behaviors are observed in HfNbTaTiZr refractory high-entropy alloy during tensile tests. Slow-avalanche and fast-runaway phases are identified by analyzing scaling relationships among slip statistics. Slow avalanches display a scaling collapse in temporal shapes, aligning with mean-field slip theory, while system-spanning fast-runaway avalanches show a Gaussian shape, indicating rapid nucleation due to dynamic weakening.
