Remedial transactions curtailment via optimization [PDF]

Serbian Journal of Electrical Engineering, 2009
The new method developed in this paper is aiming at transmission congestion management (CM). The new, Optimal Transactions Management method (OTM), is based on linear programming (LP), DC load flow (DCLF) and linear security constraints.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Advances in Transient Stability-Constrained Optimal Power Flow of Power Systems

CSEE Journal of Power and Energy Systems
Transient stability-constrained optimal power flow (TSCOPF) optimizes power flow while ensuring stability against potential contingencies. The main challenges faced by TSCOPF are the handling of transient constraints.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Distributed Optimal Power Flow for Large-Scale Multi-Area Interconnected Power Systems

CSEE Journal of Power and Energy Systems
Distributed optimal power flow (OPF) of large-scale multi-area interconnected power systems is a challenging problem. This letter proposes a distributed OPF approach based on the modified decomposition-coordination interior point method (DCIPM).

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

FEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...
