Plant pathogenic Nigrospora species have emerged as important threats to rice cultivation worldwide. During an ongoing survey of fungi associated with cultivated rice ( Oryza sativa L.) leaves in Guizhou Province, 11 Nigrospora isolates were recovered from 17 diseased leaf samples collected between April and June 2024. All isolates were obtained from rice leaf spots. Integration of detailed morphological observations with mult...

Submarine channels are critical conduits for sediment transport by turbidity currents, yet the quantitative influence of channel geometry on flow dynamics and sediment segregation remains poorly understood. Based on computational fluid dynamics, we constructed six three-dimensional numerical models of submarine channels with varying curvatures (R1–R3) and axial slopes (R4–R6) using ANSYS Fluent 17.2, with model settings inform...
