Combined Time and Information Redundancy for SEU-Tolerance in Energy-Efficient Real-Time Systems

, 2006
Recently the trade-off between energy consumption and fault-tolerance in real-time systems has been highlighted. These works have focused on dynamic voltage scaling (DVS) to reduce dynamic energy dissipation and on time redundancy to achieve transient ...

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Transient growth in Taylor-Couette flow [PDF]

, 2002
Transient growth due to non-normality is investigated for the Taylor-Couette problem with counter-rotating cylinders as a function of aspect ratio eta and Reynolds number Re. For all Re < 500, transient growth is enhanced by curvature, i.e.

Persistent and Transient Energy Poverty: A Multi-Level Analysis in Spain

, 2023
This empirical analysis investigates the determinants and dynamics of energy poverty in Spain using a combination of traditional regression models and machine learning techniques. The study identifies significant determinants of energy poverty, including income, housing type, education level, and health conditions.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

FEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Numerical calculation method of virtual nodes in complex structural composites: mechanical properties characterization and numerical simulation of combined Wbraid/Al/Epoxy functional structural materials

Defence Technology
Existing numerical methods for complex composites, such as multiscale simulation and neural network algorithms, face significant limitations. Multiscale techniques are often prohibitively expensive for large models, while neural networks struggle to ...

Transient phenomena at intermediate energies

Nuclear Physics B, 1973
Abstract Considering the experimental energy behaviours of elastic K+p, pp, πp, polarizations, we show that in helicity-flip amplitudes non-leading contributions, non-identifiable with absorptive corrections, Regge-Regge cuts or resonance tails, remain non-negligible up to ∼ 10 GeV/c. The interpretation of such contributions appears uncertain.

HVDC TRANSMISSION LINE PROTECTION BASED ON TRANSIENT ENERGY AND TRANSIENT POWER: A SURVEY

International Journal of Engineering Technologies and Management Research, 2020
As the number of consumers of electricity increases the electric power generated required to serve the consumers increases. Due to the long distance transmission of the generated power the power system becomes complex. That is why HVDC transmission system used for long distance carriage of power.
