Recognition of Failure Mode of Slope Block Failure Mode in Zhouning Pumped Storage Station Based on Stereographic Projection Method

Renmin Zhujiang, 2020
Deformation and failure of rock slope are mainly controlled by structural planes developed in rock mass. The stereographic projection method is used to analyze the failure modes of rock slope, which can easily determine the combination relationship ...

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life

FEBS Letters, EarlyView.
Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

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.

Numerical analysis of effects of adhesive type and geometry on mixed-mode failure of adhesive joint

, 2016
In the present study, the effects of the adhesive type and geometry (adhesive thickness and scarf angle) on mixed-mode failure of double scarf adhesive joint (DSJ) under uniaxial tensile loading were numerically examined using the finite element ...

Brachial pulse pressure in acute heart failure. Results of the Heart Failure Registry [PDF]

, 2019
[Abstract] Aims To investigate the still uncertain independent prognostic impact of pulse pressure (PP) in acute heart failure (HF), in particular across the left ventricular ejection fraction (EF) phenotypes, and the potential contribution of PP in ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The Reliability of a Tunnel Boring Machine [PDF]

Greater levels of complexity in tunnelling with Tunnel Boring Machine (TBM) allow higher chances of fail-ures that may increase the potential hazardous risks. This paper presents the results of a study on TBM reliability using risk analysis.

Modelling damage and failure in carbon/epoxy non-crimp fabric composites including effects of fabric pre-shear [PDF]

, 2006
A numerical material model for intra-laminar failure prediction of biaxial non-crimp fabric composites is presented. The model combines the elasto-plastic continuum damage constitutive model proposed by Ladevèze with the intra-laminar matrix failure ...
