Surface coating of cathodes is an essential process for all-solid-state batteries (ASSBs) based on sulfide electrolytes as it efficiently suppresses interfacial reactions between oxide and electrolytes. Based computational calculations, Li3PO4 has been suggested a promising material because its higher stability with sulfides optimal ionic conductivity. However, hardly applied to the ASSBs due a...

BACKGROUND AND PURPOSE Low-frequency (<0.08 Hz) fluctuations in spontaneous blood oxygen level-dependent (BOLD) signal intensity show synchronization across anatomically interconnected and functionally specific brain regions, suggesting a neural origin of fluctuations. To determine the mechanism by which high-frequency neural activity results in low-frequency BOLD fluctuations, I obtained measu...

Block and event-related stimulus designs are typically used in fMRI studies depending on the importance of detection power or estimation efficiency. The extent of vascular contribution to variability in block and event-related fMRI-BOLD response is not known. With scaling, the extent of vascular variability in the fMRI-BOLD response during block and event-related design tasks was investigated. ...

Background: Rare genetic disease studies have benefited from the era of high throughput sequencing. DNA sequencing results in diagnosis 18-40% previously unsolved cases, while incorporation RNA-Seq analysis has more recently been shown to generate significant numbers unattainable diagnoses. While methylation remains less explored, multiple inborn diseases resulting d...

Background: Exercise leads to changes in hormonal concentration and metabolites which impacts growth development; during physical activity, energy metabolism is influenced by hormones associated with pubertal development, characterization of its response exercise essential. Therefore, we aimed identify the effects on thyroid children adolescents ...

Analyses of intrinsic fMRI BOLD signal fluctuations reliably reveal correlated and anticorrelated functional networks in the brain. Because the BOLD signal is an indirect measure of neuronal activity and anticorrelations can be introduced by preprocessing steps, such as global signal regression, the neurophysiological significance of correlated and anticorrelated BOLD fluctuations is a source o...
