Comments on Minimum Volume Simple and Compensated Superconducting Coils

Whole Body Screening Using High-Temperature Superconducting MR Volume Coils:

Previous studies on HTS coils can be put into two categories: tape surface coils and thin-film surface coils[1-4]. In this study, we build a whole new Bi2Sr2Ca2Cu2O3 (Bi-2223) superconducting volume coil (length of 8 cm) designed for the mice whole body imaging at Bruker 3T MRI system. The HTS volume coil has 2.3 folds higher S/N than that of the HTS volume coil at 300K for the mice body screen...

Maximum Load and Minimum Volume Structural Optimization

A bi-criteria optimization is considered whose objectives are the maximization of the load sustained by a structure and the minimization of the structure's volume. As the objectives are conflicting, the solution to the problem is of the Pareto type. The problem is elaborated for a thin-walled column of cruciform cross-section, prone to flexural and torsional buckling. A numerical example is als...

Comments on Nonfinite Adverbial Patterns in English Prose Fiction: A Simple Model for Analysis and Use

This study aims to present an accessible model of some frequent nonfinite adverbial types occurring in English prose fiction. As its main syntactic argument, it recognizes that these adverbials are mostly elliptical in that there are some dependent-clause markers one can assume to be implicit when supplying those elements back into the clause complex. Some comments are provided at the end on th...

Birdcage volume coils and magnetic resonance imaging: a simple experiment for students

Background This article explains some simple experiments that can be used in undergraduate or graduate physics or biomedical engineering laboratory classes to learn how birdcage volume radiofrequency (RF) coils and magnetic resonance imaging (MRI) work. For a clear picture, and to do any quantitative MRI analysis, acquiring images with a high signal-to-noise ratio (SNR) is required. With a give...
