Dynamic structure selection and instabilities of driven Josephson lattice in high-temperature superconductors [PDF]

, 2001
We investigate the dynamics of the Josephson vortex lattice in layered high-T$_{c}$ superconductors at high magnetic fields. Starting from coupled equations for superconducting phases and magnetic field we derive equations for the relative displacements [

Cerebrospinal Fluid Liquid Biopsy Enables Targeted Therapy Without Tissue Diagnosis in Pediatric Low‐Grade Gliomas With BRAF V600E Mutation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...

Analytical static voltage stability boundary based on holomorphic embedding

International Journal of Electrical Power & Energy Systems, 2022
Abstract This paper proposes a novel analytical method to calculate the Static Voltage Stability Boundary (SVSB) for power systems as a hypersurface in a high-dimensional space on power flow solutions. First, the proposed method derives the analytical voltage solution of AC power flows in the form of Multivariate Power Series (MPS) using the ...
