Title: A high-efficiency low-wearing hybrid voltage regulator for utility applications
Author: Zhao, Tiefu, Wang, Yafeng
Date Created: 2023
Subjects--Topical: Voltage regulators, Electric power distribution
Description: Step voltage regulator (SVR) has been utilized in power distribution systems for decades as the voltage regulation device. Due to the increasing integration of distributed energy resources, the conventional SVR is severely challenged by the modern...

Title: An all optical approach for comprehensive in-operando analysis of radiative and nonradiative recombination processes in GaAs double heterostructures
Author: Zhang, Y. (Yong), 1960-, Zhang, Fan, Castaneda, Jose, Gfroerer, Timothy, Friedman, Daniel, Zhang, Yong-Hang, Wanlass, Mark W.
Subjects--Topical: Optics, Photoluminescence
Description: We demonstrate an all optical approach that can surprisingly offer the possibility of yielding much more information than one would expect, pertinent to the carrier recombination dynamics via both radiative and nonradiative processes when only one...

Title: COVID-19 pandemic severity, lockdown regimes, and people’s mobility : early evidence from 88 countries
Author: Thill, Jean-Claude, Rahman, Md. Mokhlesur, Paul, Kamal Chandra
Subjects--Topical: Public health, COVID-19 (Disease), Social distancing (Public health)
Description: This study empirically investigates the complex interplay between the severity of the coronavirus pandemic, mobility changes in retail and recreation, transit stations, workplaces, and residential areas, and lockdown measures in 88 countries aroun...

Title: Contrastive learning‑based pretraining improves representation and transferability of diabetic retinopathy classification models
Author: Alam, Minhaj Nur, Yamashita, Rikiya, Ramesh, Vignav, Prabhune, Tejas, Lim, Jennifer I., Chan, R. V. P., Hallak, Joelle, Leng, Theodore, Rubin, Daniel
Date Created: 2023
Subjects--Topical: Diabetic retinopathy, Diabetes
Description: Diabetic retinopathy (DR) is a major cause of vision impairment in diabetic patients worldwide. Due to its prevalence, early clinical diagnosis is essential to improve treatment management of DR patients. Despite recent demonstration of successful...

Title: Joint power control and routing for rechargeable wireless sensor networks
Author: Nasipuri, Asis, Pal, Amitangshu
Date Created: 2016
Description: Wireless sensor networks (WSN) that are powered by energy harvested from the environment, also known as rechargeable WSNs, typically experience wide variations of energy availability across the network. Such variations can cause frequent node outa...

Title: Multiple-stage structure transformation of organic-inorganic hybrid Perovskite CH3NH3PbI3
Author: Zhang, Y. (Yong), 1960-, Chen, Qiong, Kim, Hui-Seon, Liu, Yucheng, Yang, Mengjin, Yue, Naili, Ren, Gang, Zhu, Kai, Lu, Shengzhong, Park, Nam-Gyu
Subjects--Topical: Physics, Perovskite
Description: By performing spatially resolved Raman and photoluminescence spectroscopy with varying excitation wavelength, density, and data acquisition parameters, we achieve a unified understanding towards the spectroscopy signatures of the organic-inorganic...

Title: Power characteristics of planar index-antiguided waveguide lasers with transverse mode competition
Author: Her, Tsing-Hua, Wang, Chaofan, Liu, Yuanye, Casperson, Lee W.
Subjects--Topical: Lasers, Lasers--Resonators
Description: We report comprehensive analysis of output characteristics of homogeneously broadened index-antiguided slab lasers with transverse mode competition. Robust single fundamental mode operation is achieved when the distributive modal loss due to index...

Title: Predicting lightning-related outages in power distribution systems : a statistical approach
Author: Chowdhury, Badrul, Doostan, Milad
Subjects--Topical: Machine learning, Electric power distribution--Communication systems, Lightning
Description: This paper presents a novel data-driven approach for predicting lightning-related outages that occur in power distribution systems on a daily basis. In order to develop an approach that is able to successfully fulfill this objective, there are two...
