An analysis of flow-like motion of avalanches based on physical modeling experiments

Shuiwen dizhi gongcheng dizhi, 2022
Flow-like motion is the main forms of rock avalanche emplacement, which is the foundation to reveal the dynamic mechanisms of rock avalanches. In this paper, a series of physical modeling experiments based on the Particle Image Velocimetry（PIV）analysis ...

Flow variation at multiple scales filters fish life histories and constrains community diversity in desert streams

Ecosphere, 2022
Environmental regimes, which encompass decadal‐scale or longer variation in climate and disturbance, shape communities by selecting for adaptive life histories, behaviors, and morphologies.

A discriminative method to flow regimes based on the flow resistance law

Shui kexue jinzhan
Upper- and lower-flow regimes are formed under different conditions. To identify them is important for predicting mobile bed resistance. Based on the dimensionless resistance equation, a new discriminant function to flow regimes is deduced, which ...

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

The salmonid and the subsurface: Hillslope storage capacity determines the quality and distribution of fish habitat

Ecosphere, 2023
Water in rivers is delivered via the critical zone (CZ)—the living skin of the Earth, extending from the top of the vegetation canopy through the soil and down to fresh bedrock and the bottom of significantly active groundwater. Consequently, the success
