INTRODUCTION: It has been shown that high-permittivity dielectric pads can be used to efficiently improve the field homogeneity in the region of interest (ROI) in high-field MRI [1-8]. Recent studies focused on the design of these pads by controlling parameters such as size, position and permittivity, using simple patient specific parameter sweeping to improve the transmit field in a small regi...

Background Psychiatric advance directives (PADs) provide a legal means for competent individuals to refuse or consent to future mental health treatment during periods of decisional incapacity. Previous studies have shown high potential demand for PADs but low rates of completion in the United States, despite new laws authorizing PADs in over 20 states. This paper reports the results of the firs...

Primary antibody deficiencies (PAD) are a group of immune system disorders, associated with decreased levels of secretory and protective immunoglobulins. Because of the important role of immunoglobulins in the protection of oral cavity, patients with PADs are more susceptible to dental caries or oral manifestations. This study was performed to investigate the oral and dental manifestations of P...

conclusions considering the unique construct of the powerlink stents, this is thought to represent aneurysmal degeneration of the outer fabric material from the metal struts and may potentially pressurize the excluded sac with risk for rupture. case presentation a 65-year-old woman who had endovascular aortic repair (evar) of an abdominal aortic aneurysm with endologix powerlink system develope...

Many stick insects and mantophasmids possess tarsal 'heel pads' (euplantulae) covered by arrays of conical, micrometre-sized hairs (acanthae). These pads are used mainly under compression; they respond to load with increasing shear resistance, and show negligible adhesion. Reflected-light microscopy in stick insects (Carausius morosus) revealed that the contact area of 'heel pads' changes with ...

A new structure design of bond pad is proposed to reduce its parasitic capacitance in general CMOS processes without extra process modification. The proposed bond pad is constructed by connecting multilayer metals and inserting additional diffusion layers into the substrate below the metal layers. The metal layers except top metal layer are designed with special patterns, which have smaller are...

BACKGROUND Dual-channel transmit technology improves the image quality in cardiovascular magnetic resonance (CMR) at 3 T by reducing the degree of radiofrequency (RF) shading over the heart by using RF shimming. Further improvements in image quality have been shown on a dual-transmit system using high permittivity pads. The aim of this study is to investigate the transmit field (B 1 (+)) homoge...
