, 2021 Data was generated for 98 debris flow erosion experiments in a 5.4 m long flume with an erodible loosely packed sediment bed. In the 98 experiments the bed conditions were kept constant, but the composition of the debris flow changed.

The distribution of debris flows and debris flow hazards in southeast China [PDF]
WIT Transactions on Engineering Sciences, 2010 Debris flows commonly occur throughout southern China, posing a hazard to people, property and infrastructure. Although debris flows occur more frequently and with greater magnitude in mountainous southwest China, where they have been studied extensively, their impacts on society are greater in southeast China, where population densities and land use ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Debris-flow erosion and deposition dynamics [PDF]
, 2011 Debris flows are a major natural hazard in mountains world wide, because of their destructive potential. Prediction of occurrence, magnitude and travel distance is still a scientific challenge, and thus research into the mechanics of debris flows is ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Assessing the dynamic influences of slope angle and sediment composition on debris flow behaviour: An experimental approach [PDF]
, 2011 Debris flows are hazards that can inflict significant infrastructural damage and loss of life. Their rapid and unpredictable onset in isolated locations means that field studies are limited.
