Placing EU banks under undue stress. CEPS Commentary, 2 December 2011 [PDF]

open access: yes, 2011
This Commentary surveys the latest round of stress tests administered to EU banks by the European Banking Authority (EBA) and finds their exclusive focus on a single measure of capital, the Tier 1 capital ratio of Basel III, short-sighted.

Stress-sign-tunable Poisson’s ratio in monolayer blue phosphorus oxide [PDF]

open access: yesJournal of Physics: Condensed Matter, 2019
Negative Poisson's ratio (NPR) materials have attracted tremendous interest due to their unusual physical properties and potential applications. Certain two-dimensional (2D) monolayer materials have also been found to exhibit NPR and the corresponding deformation mechanism varies.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

True triaxial test and failure criterion of coal gangue concrete

open access: yesMeitan xuebao
In view of the pollution caused by the large storage of coal gangue and the shortage of natural aggregate in concrete, using coal gangue as coarse aggregate is a reasonable way to solve the above problems.

Experimental Study on the Dynamic Modulus and Damping Ratio of Compacted Loess under Circular Dynamic Stress Paths

open access: yesAdvances in Civil Engineering, 2021
Dynamic loads such as earthquakes and traffic will simultaneously generate vertical dynamic stress and horizontal shear stress in the foundation soil. When the vertical dynamic stress amplitude is twice the horizontal shear dynamic stress amplitude, and ...

Peristaltic Pumping of Blood Through Small Vessels of Varying Cross-section

open access: yes, 2012
The paper is devoted to a study of the peristaltic motion of blood in the micro-circulatory system. The vessel is considered to be of varying cross-section. The progressive peristaltic waves are taken to be of sinusoidal nature. Blood is considered to be

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Study on Crack Propagation of Steel for Coiled Tubing Based on Extended Finite Element Method

open access: yesShiyou jixie, 2019
Fatigue crack propagation is the main cause of coiled tubing failure. To address the cumbersome testing study work of the crack propagation process of steel for coiled tubing, the extended finite element method (XFEM) was introduced for analysis.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

open access: yesMolecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...
