A tabletop, ultrashort pulse photoneutron source driven by electrons from laser wakefield acceleration

open access: yesMatter and Radiation at Extremes, 2017
Relativistic electron beams driven by laser wakefield acceleration were utilized to produce ultrashort neutron sources. The experiment was carried out on the 38 fs, ∼0.5 J, 800 nm Ti:Sapphire laser in the 10 TW UT3 laser lab at University of Texas at ...

Association between adiposity outcomes and residential density: a full-data, cross-sectional analysis of 419 562 UK Biobank adult participants

open access: yesThe Lancet Planetary Health, 2017
Background: Obesity is a major health issue and an important public health target for urban design. However, the evidence for identifying the optimum residential density in relation to obesity has been far from compelling.

Monitoring BaTiO3 sintering using nanosecond pulsed electric field

open access: yesScience and Technology of Advanced Materials: Methods
Sintering is a critical process in ceramic fabrication, conducted in electric furnaces. However, the conditions within these furnaces remain largely unobservable, necessitating the development of real-time monitoring techniques.

Bone Mineral Density of Adolescent Female Tennis Players and Nontennis Players

open access: yesJournal of Osteoporosis, 2012
The purpose of this study was to determine differences in bone mineral density (BMD) among adolescent female tennis players (TPs) and nontennis players (NTPs) and to assess body composition as a predictor variable of BMD.

Examination of pyroelectric power generation over a wide temperature range by controlling the Zr:Sn composition ratio of PLZST

open access: yesJournal of Asian Ceramic Societies, 2021
Several studies have been conducted on energy harvesting, which involves conversion of unused environmental energy into a power source. More than half of the energy consumed is wasted as heat.

Density-on-Density Regression

open access: yes, 2023
In this study, a density-on-density regression model is introduced, where the association between densities is elucidated via a warping function. The proposed model has the advantage of a being straightforward demonstration of how one density transforms into another.

Exploring Preferences for a Digital Single‐Session Intervention for Adolescent Siblings of Youth With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.
