Optimal integration of DSTATCOM using improved bacterial search algorithm for distribution network optimization

open access: yesAlexandria Engineering Journal, 2022
Due to the non-linear nature of most of the loads, there is a greater demand for reactive power in the distribution network. Further, it wasted high energy on distribution and dropped the bus voltages.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Fast-Switching-Speed, Low-Forward-Voltage-Drop Static Induction(SI) Thyristor.

open access: yesIEEJ Transactions on Industry Applications, 1995
An SI thyristor using a normally-off planar-gate structure in a low power class has been developed for the use as a power switching device in a three-phase inverter circuit. A 600V-15A class SI thyristor with very fast switching time (tgt, tgq) and low forward voltage drop (VTM) was designed and fabricated.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
