Introduction: Birdcage coils become difficult to build at high field strength, as smaller capacitor values are required and coil sections become large relative to the RF wavelength. This abstract demonstrates a birdcage coil operating at 600MHz (λfree space=0.5m) for small animal imaging. Methods: A 12-rung high-pass design was chosen (50mm diameter × 32mm long, 2mm track width; 120mm diameter ...

Introduction: Ongoing effort is directed to developing methods for improving spectral resolution and quantification of brain metabolites at pre-clinical and clinical field strengths. Recently, a constant-time approach has been applied in conjunction with localized MRS techniques towards this goal (1-3). In order to improve the detection of overlapping brain metabolites without inducing coherenc...

This paper will present data manipulation and statistical analysis across multiple database types and architectures using JMP. These methodologies generate advanced statistical process control strategies to detect and rectify semiconductor production tool deterioration. Examples of data analysis and presentation via JMP will be used to highlight the importance of comprehendible statistical anal...

Objective: To establish sodium MRI as a non-invasive method for measuring intervertebral disc proteoglycan content Introduction: Intervertebral disc (IVD) degeneration is a common and sometimes debilitating condition, incurring tremendous financial cost on society. The initial stage of IVD degeneration involves the breakdown of proteoglycans (PG) in the nucleus pulposus (NP) region of the disc[...

It is estimated that about 18 million people worldwide suffer from dementia and it is projected to increase to about 35 million by the year 2025. All types of dementia occur due to an aberration in memory retention and development, caused by malfunctioning neurons. Experimental investigation of the dynamics of biological networks is a fundamental step towards understanding how the nervous syste...

Shielding an object to be undetectable is an important issue for engineering applications. Cloaking is the ultimate shielding example, routing waves around an object without mutual interaction, demonstrated as possible in principle by transformation and metamaterial techniques. Example applications have been successfully designed and validated for electromagnetic wave, thin plate flexural wave,...

Computed Tomography (CT) scanning has served as an important non-destructive research tool by providing twoand three-dimensional images particularly in medicine, biology and materials science. An example of its application in the area of materials is reported. Experimental study was carried out to investigate the effect of location within column element on the strength and porosity characterist...

GaN layers were grown on Si (111) by MOCVD using epitaxial single crystal rare-earth oxide buffer which helps to solve mechanical strain related problems arising due to lattice and thermal expansion mismatch between the III-N layer and the substrate. Chemical stability of the rare-earth oxide in contact with silicon as well with GaN is analyzed. Transformation of rare-earth oxide to rare earth ...
