Silicon-on-insulator ~SOI! has proven to be a viable alternative to traditional bulk silicon for fabrication of complementary metal–oxide–semiconductor devices. However, a number of unusual phenomena with regards to diffusion and segregation of dopants in SOI have yet to be explained. In the present study, SOITEC wafers were thinned to 700 and 1600 Å using oxidation and etching. Ion implantatio...

Silicon substrate losses and non-linearities were the limiting characteristics of Si-based MOSFET technologies to provide low-power and low-cost solutions to the mobile RF device market. Thanks to the trap-rich Silicon-on-Insulator (SOI) substrate invented at UCL and developed in collaboration with the French company SOITEC, RF SOI is becoming a mainstream technology which is implemented in all...

BACKGROUND To investigate prevalence and risk factors for post stroke pneumonia (PSP) in patients with acute ischemic stroke treated at stroke units (SU). METHOD We analysed data from the Austrian Stroke Unit registry concerning admissions from January 2003 to December 2013 and assessed the prevalence of PSP at the stroke unit. Patients with and without PSP were compared in univariate and mul...

Objectives. To explore the clinical correlates of nonmotor symptoms (NMS) in progressive supranuclear palsy (PSP) and their differences from healthy controls and patients with Parkinson's disease (PD). Methods. Twenty-seven PSP patients, 27 age- and gender-matched healthy controls (HC), and 27 age- and gender-matched PD patients were included for this case-control study. NMS were assessed using...

Prostatic secretion protein (PSP) or estramustine-binding protein is a major protein in rat ventral prostate. The amount of PSP was measured per mg of cytosolic protein at different ages and after castration or administration of sex hormones. The amount of PSP is relatively low before puberty (25 microgram/mg of protein) but increases at about 28 days of age to about 670 microgram/mg of protein...

Background and Aim: Clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. The aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (PSP) and CBCT in the detection of horizontal and vertical root fractures (HRF and VRF). Materials and Methods: For this experimental stud...

INTRODUCTION Progressive supranuclear palsy (PSP) is characterized by early postural instability and backward falls. The mechanisms underlying backward postural instability in PSP are not understood. The aim of this study was to test the hypothesis that postural instability in PSP is a result of dysfunction in the perception of postural verticality. METHODS We gathered posturography data on 1...

ÐThe Personal Software Process is a process improvement methodology aimed at individual software engineers. It claims to improve software quality (in particular defect content), effort estimation capability, and process adaptation and improvement capabilities. We have tested some of these claims in an experiment comparing the performance of participants who had just previously received a PSP co...

The Personal Software Process (PSP) is used by software engineers to gather and analyze data about their work. Published studies typically use data collected using the PSP to draw quantitative conclusions about its impact upon programmer behavior and product quality. However, our experience using PSP in both industrial and academic settings revealed problems both in collection of data and its l...

BACKGROUND AND PURPOSE Three-dimensional imaging and hemispheric volumetry are useful for the assessment of degenerative cortical atrophy. Our purpose was to determine the features of cortical atrophy in progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) by means of a hemispheric surface display generated with MR images. METHODS The extent of cortical atrophy was evaluat...
