Rigorous Mathematical Steps for Sensitivity Analysis of High Impedance Ground Fault Detection in Power Distribution Systems

open access: yesCogent Engineering, 2020
A literature survey indicated that high impedance fault (HIF) detection methods employ simulation techniques using very low voltage signals generated using software such as PSCAD, and MATLAB, among others.

The dimension and components of symmetric algebras

open access: yesJournal of Algebra, 1986
Let M be a finitely generated R-module, with R a Noetherian ring. The authors first give the following formula for the dimension of the symmetric algebra of \(M: \dim S(M)=Max\{\dim R/p+\mu (M_ p)\}\) over all \(p\in Spec R\). Here, \(\mu (M_ p)\) is the minimal number of generators of \(M_ p\). A consequence is that dim S(M)\(\geq \mu (M)\).

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Extraction of Symmetrical Components and Fault Indication [PDF]

open access: yes, 2015
At present the conventional and practical problems are being solved by computer based software known as Simulation software due to their higher precision and accuracy. In our project we encounter one of such problems like the following.

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 ...

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 ...

Symmetrical components estimation through nonrecursive Newton-type numerical algorithm

open access: yes, 2003
The paper reports new software developments for symmetrical components estimation. Nonrecursive Newton-type algorithm is extended with the second stage algorithm for symmetrical components calculation from the estimated fundamental phasors of three-phase

Behaviour of Induction Machines under Fault Conditions – Application of the Instantaneous Symmetrical Components Method [PDF]

open access: yes, 2018
Although the method of symmetrical components is commonly used in investigating unbalanced operation of electrical machines and power systems, its application in the analysis of transient behaviour of electrical machines can be advantageous.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
