A COMPUTER CALCULATION FOR TENTATIVE ELECTRICAL SYSTEM IMPROVEMENT BY REACTIVE POWER COMPENSATION CONSIDERING SYSTEM UNBALANCED [PDF]

, 2013
An improvement of unbalanced distribution system operation is carried out by reactive power compensation. The lagging reactive power demand is compensated by allocating a number of three-phase shunt capacitors.

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

FEBS 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.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Flexible mesh-shaped distribution network topology with adaptive geographical layered-clustered probabilistic planning

International Journal of Electrical Power & Energy Systems
With the large-scale integration of distributed renewable energy, traditional distribution network topologies lack the flexibility to fully exploit wide-area source-load complementarity and flexible resources, limiting the efficient and secure ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Interruption strategy of fault current fed by high-capacity generator based on phase selection and current-zero prediction

International Journal of Electrical Power & Energy Systems
The high asymmetrical degree (AD, >100 %) of the fault current fed by high-capacity turbine generator (HTG) results in high arc energy (Earc), hindering reliable interruptions of generator circuit breakers (GCBs). Traditional GCBs with simultaneous three-

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
