Coordinated Optimization of Generator Excitation System for Improving Transmission Capacity of Power System

open access: yesZhongguo dianli, 2019
For long-distance AC transmission system from energy base to load center, the system damping is insufficient when N–1 fault occurs, which leads to the reduction of transmission capacity.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS 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 ...

STABILITY AND GENERICITY IN DYNAMICAL SYSTEMS [PDF]

open access: yes, 1980
A general reference to this subject, with examples, written about the summer of 1967 is [7], (reported in a recent Bourbaki seminar by C. Godbillon). Here I will try to emphasize developments since. An important source of much of this more recent work should appear in the immediate future in [1].

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

PB3D: a new code for edge 3-D ideal linear peeling-ballooning stability [PDF]

open access: yes, 2017
A new numerical code PB3D (Peeling-Ballooning in 3-D) is presented. It implements and solves the intermediate-to-high-n ideal linear magnetohydrodynamic stability theory extended to full edge 3-D magnetic toroidal configurations in previous work [1]. The

Dynamic instability modeling on phase plane for thin aeroshell capsule with pitching motion at transonic speed

open access: yesMechanical Engineering Journal
For sample return missions from deep space, a thin aeroshell capsule was proposed aimed at mitigating the aerodynamic heating during its reentry into the earth's atmosphere.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Stability boundary analysis of the dynamic voltage restorer in weak systems with dynamic loads

open access: yes, 2011
In this contribution, a stability analysis for a dynamic voltage restorer (DVR) connected to a weak ac\ud system containing a dynamic load is presented using continuation techniques and bifurcation theory.
