The birdcage (BC) coil is currently being utilized for uniform radiofrequency (RF) transmit/receive (Tx/Rx) or Tx-only configuration in many magnetic resonance (MR) imaging applications, but insufficient magnetic flux (|B1|) density and their non-uniform distribution still exists in high-field (HF) environments. We demonstrate that the asymmetric birdcage (ABC) transmit/receive (Tx/Rx) volume c...

We have de novo designed a heterodimeric coiled-coil formed by two peptides as a capture/delivery system that can be used in applications such as affinity tag purification, immobilization in biosensors, etc. The two strands are designated as K coil (KVSALKE heptad sequence) and E coil (EVSALEK heptad sequence), where positively charged or negatively charged residues occupy positions e and g of ...

A 5 year old girl underwent recanalisation after coil embolisation of a persistent ductus arteriosus. Recanalisation is uncommon after coil embolisation and may be related to shrinkage of the coil, a change in its position, and ductal shape.

We study how the critical gradient depends on the coil lay-out in a superconducting quadrupole for particle accelerators. We show that the results relative to a simple sector coil are well representative of the coil lay-outs that have been used to build several quadrupoles in the past 30 years. Using a semi-analytical approach we derive a formula that gives that critical gradient as a function ...

Allethrin, present in mosquito coil is a pyrethroid pesticide. Pyrethroids are used as insecticides worldwide. Self poisoning with mosquito coil is very rare. We describe a case of attempted suicide by consumption of mosquito coil. Patient recovered without any sequel.

Introduction: In previous work, we introduced the concept of the multi-mode intravascular MRI coil [1,2] which consists of a single active device that is connected to the external system via a single coaxial cable and performs three functions: 1) active tip tracking, 2) imaging, and 3) inductively-coupled wireless marker. The purpose of such a multi-functional coil is to enable single insertion...

PURPOSE Research has shown that the orientation of the exiting wire from a scleral search coil (nasal in the original coil, inferior in the modified coil) influences the pattern of torsion associated with blinks, presumably due to the upper eyelid touching the wire. The present study was conducted to investigate whether coil wire orientation also influences the pattern of torsion during fixatio...

There is an interest in designing superconducting magnet systems working a persistent current mode. These continuously generate magnetic fields with disconnected power sources that work like permanent devices. This paper proposes magnet-system concept based on direct mechanical energy transfer the field. Short circuited coils do not have leads and sources. To pump coil, magnetizer used magnetic...
