Effective optimal design of 3-D magnetic device having complicated coil using edge element and Biot-Savart method [PDF]

, 2002
It is troublesome and time consuming to treat a coil of complicated shape with optimization methods using edge elements, because the current vector potential in the coil of changed shape (changed mesh) should be calculated at each iteration of the ...

Comparison of In Vivo Selection and Rational Design of Heterodimeric Coiled Coils [PDF]

Structure, 2002
To investigate how electrostatic interactions restrict the associations of coiled coils, we improved a heterodimeric coiled coil (WinZip-A1B1) by in vivo selection and, alternatively, by rational design. Selection from libraries encoding variable edge (g and e) residues enriched g/e' ion pairs, but the optimum selected heterodimers unexpectedly ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

On the application of radio frequency voltages to ion traps via helical resonators

, 2011
Ions confined using a Paul trap require a stable, high voltage and low noise radio frequency (RF) potential. We present a guide for the design and construction of a helical coil resonator for a desired frequency that maximises the quality factor for a ...

Properties of a new quasi-axisymmetric configuration [PDF]

, 2018
A novel, compact, quasi-axisymmetric configuration is presented which exhibits low fast-particle losses and is stable to ideal MHD instabilities. The design has fast-particle loss rates below 8\% for flux surfaces within the half-radius, and is shown to ...

Optimization of a Coil System for Generating Uniform Magnetic Fields inside a Cubic Magnetic Shield

Energies, 2018
Ultra-low magnetic fields have drawn lots of attention due to their important role in scientific and technological research. The combination of a magnetic shield and an active compensation coil is adopted in most high performance magnetically shielded ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...
