A novel, compact RF linac structure, the plane wave transformer (PWT), is studied. The PWT provides high accelerating field and high efficiency, and can be used to accelerate high-brightness beams. PWT linac prototypes with eight cells at S-band have been developed at UCLA and successfully used to accelerate an electron beam by more than 10 MeV in 40 cm. In this paper, we describe the principal...

BackgroundLeft ventricular (LV) geometric patterns aid clinicians in the diagnosis and prognostication of various cardiomyopathies. Two-dimensional transthoracic echocardiogram is clinical standard for assessment LV dimensions. Assessment dimensions wall thickness known to be associated with significant interobserver intraobserver variability. Automation echocardiographic interpretation using m...

We compared the changes in ambulatory outcomes between men and women with symptomatic peripheral arterial disease (PAD) following completion of a supervised, on-site, treadmill exercise program, and we determined whether exercise training variables and baseline clinical characteristics were predictive of changes in ambulatory outcomes in men and women. Twenty-three men and 25 women completed th...

This paper sheds light on two problems in the Penn World Table (PWT) GDP estimates. First, we show that these estimates vary substantially across different versions of the PWT despite being derived from very similar underlying data and using almost identical methodologies; that this variability is systematic; and that it is intrinsic to the methodology deployed by the PWT to estimate growth rat...

A task-specific tremor (TST) is a rare form of movement disorder that appears while performing or attempting to perform a particular task. Primary writing tremor (PWT) is the most common form of TST which only occurs during the act of writing and hinders it.

In order to provide maximum physics benefits, the International Linear Collider (ILC) must have a highly polarized electron beam with a low emittance. High electron spin -polarization (>85%) is attainable with a modern GaAs photocathode illuminated by a circularly polarized laser. Low emittance is achievable with an rf photoinjector, and can be further improved with a round-to-flat beam transfo...

UNLABELLED Thirty-four subjects with symptomatic peripheral arterial disease (PAD) or critical limb ischmeia (CLI) who were experiencing claudication pain, chronic resting pain, numbness, and ischemic lower leg/foot ulceration were randomized into 2 treatment groups. MATERIALS AND METHODS Eighteen of these patients received treatment with high-pressure, intermittent pneumatic compression (HPI...

The temperature dependences of the unfolding-refolding reaction of a shorter version of the alpha-spectrin SH3 domain (PWT) used as a reference and of two circular permutants (with different poly-Gly loop lengths at the newly created fused loop) have been measured by differential scanning microcalorimetry and stopped-flow kinetics, to characterize the thermodynamic nature of the transition and ...
