The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

True triaxial test and failure criterion of coal gangue concrete

Meitan 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

Advances 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 ...

Scaling of the Strain Hardening Modulus of Glassy Polymers with the Flow Stress

, 2009
In a recent letter, Govaert et al. examined the relationship between strain hardening modulus $G_r$ and flow stress $\sigma_{flow}$ for five different glassy polymers.

Analysis of Stress Ratio and Stress Regime in West Java

Indonesian Journal on Geoscience
This study actively investigates stress ratios, principal stress orientations, and stress regimes in the West Java Province, Indonesia, by simultaneously inverting both the stress tensor and fault orientations from 232 moment tensors. It identifies diverse stress regimes, including normal and reverse faulting in the subduction zone, as well as mixed ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

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

, 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.

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

FEBS 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.

The Effect of Multiple Factors on the Fatigue Crack Growth Behavior of DH36 Steel in Arctic Environment

Journal of Marine Science and Engineering
In Arctic regions, ship structures face low temperatures, overloads, thickness effects, and fluctuating stress ratios, which significantly influence the fatigue crack growth (FCG) behavior of marine steels.

Multiple Fully Stressed Structural Designs and the Stress Ratio Method

Computer-Aided Civil and Infrastructure Engineering, 1995
Some structures are capable of being proportioned in several different ways such that each one is a fully stressed design. This paper investigates the nature of these multiple fully stressed designs, the relationships that exist between them, and the behavior of the stress ratio method when applied to the sizing of such structures.
