Discrete variable approaches to tetratomic molecules: part I: DVR(6) and DVR(3) + DGB methods.

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 2002
We present two discrete variable representation (DVR) based methods for the determination of the vibrational energy levels of tetratomic molecules. Both methods are designed for orthogonal internal coordinates in a body-fixed reference frame and make use of the DVR of three angular variables.

Improved dynamic voltage restorer with reduced capacity of power inverter and energy storage for voltage sag mitigation

IET Power Electronics, 2021
As one of the most representative series active compensators, dynamic voltage restorer (DVR) can solve voltage‐related power quality uses effectively. The in‐phase voltage control and energy‐optimised control are the two typical control strategies of DVR.

Attenuation of Zero Sequence Voltage Using a Conventional Three-Wire Dynamic Voltage Restorer

Energies, 2021
Voltage sags/swells and harmonics are recurring problems in electric energy distribution systems. In order to solve these issues, several dynamic voltage restorer (DVR) topologies, such as the conventional three-wire DVR, have been proposed in the ...

DTI-ALPS as a Biomarker of Small Vessel Disease Progression and Amyloid-β in Normal Aging: A 3-Year Longitudinal Study. [PDF]

Hum Brain Mapp
A higher DTI‐derived ALPS index relates cross‐sectionally to both quantitative and visual measures of SVD and is associated with short‐term amyloid‐β accumulation in cognitively normal older adults. Also, greater amyloid burden and choroid plexus volume are associated with a more rapid deterioration in global cognition and processing speed.

Proteogenomic Profiling of Idiopathic Pulmonary Arterial Hypertension Identifies Sex-Differential Proteins and Candidate Therapeutic Targets. [PDF]

Adv Sci (Weinh)
An integrated proteogenomic analysis of 44,137 predominantly European‐ancestry UK Biobank participants aged 40–69 years identifies 12 robust proteins associated with idiopathic pulmonary arterial hypertension. These proteins define a high‐mortality molecular endotype, support early detection and mortality prediction, reveal sex‐differential proteomic ...

Network‐dependent remote effects and local tau burden jointly shape neuronal dysfunction in Alzheimer's disease [PDF]

Alzheimers Dement
Abstract BACKGROUND Tau pathology in Alzheimer's disease (AD) propagates along the brain's connectome, yet the mechanisms by which tau drives neuronal dysfunction remain unclear. We hypothesized that dysfunction primarily emerges in regions close to tau‐harboring epicenters. METHODS One hundred thirty‐one amyloid‐positive individuals underwent dynamic [
