A Hierarchical Control Approach for Power Loss Minimization and Optimal Power Flow within a Meshed DC Microgrid

open access: yesEnergies, 2021
This work considers the DC part of a hybrid AC/DC microgrid with a meshed topology. We address cost minimization, battery scheduling and the power loss minimization within the power distribution network through constrained optimization. The novelty comes

Examining the Effects of Emotional Valence and Arousal on Takeover Performance in Conditionally Automated Driving [PDF]

open access: yesTransportation Research Part C: Emerging Technologies, 2020
In conditionally automated driving, drivers have difficulty in takeover transitions as they become increasingly decoupled from the operational level of driving.

Valence and patterning of aromatic residues determine the phase behavior of prion-like domains

open access: yesScience, 2020
Not too sticky There is increasing evidence for a role of liquid-liquid phase separation (LLPS) in many cellular processes. Many proteins that undergo LLPS include prionlike domains (PLDs), which are enriched in polar amino acids and often interspersed ...

Hierarchical nickel valence gradient stabilizes high-nickel content layered cathode materials

open access: yesNature Communications, 2021
High-nickel content cathode materials offer high energy density. However, the structural and surface instability may cause poor capacity retention and thermal stability of them.

Biasing actions by incentive valence in an approach/avoidance task [PDF]

open access: yes, 2019
The present study investigates interactions between incentive valence and action, which mirror wellknown valence-action biases in the emotional domain.

Lattice oxygen activation enabled by high-valence metal sites for enhanced water oxidation

open access: yesNature Communications, 2020
Anodic oxygen evolution reaction (OER) is recognized as kinetic bottleneck in water electrolysis. Transition metal sites with high valence states can accelerate the reaction kinetics to offer highly intrinsic activity, but suffer from thermodynamic ...

A Case of Delayed Diagnosis of Bilateral Ureteral and Bladder Injury after Laparoscopic Hysterectomy: An Unusual Complication

open access: yesCase Reports in Urology, 2012
The incidence of ureteral and bladder lesions after laparoscopic hysterectomy is the most encountered urinary complication in gynaecological surgery. We report the unusual case of 42-year-old woman who had a delayed diagnosis of bilateral ureteral injury
