The stability of a thin plasma foil accelerated by the radiation pressure of a high intensity electromagnetic (e.m.) pulse is investigated analytically and with particle in cell numerical simulations. It is shown that the onset of a Rayleigh-Taylor-like instability can lead to transverse bunching of the foil and to broadening of the energy spectrum of fast ions. The use of a properly tailored e...
BACKGROUND The report presents evaluation results from an intervention using specially produced foil packs to promote a transition from heroin injecting to inhalation (chasing) with injecting drug users (IDUs) attending four needle and syringe programmes (NSPs) in south west England. METHODS Service activity/uptake measures, brief structured interviews. RESULTS Out of 320 attenders, 54% too...
Various structures have been reported for dermoscopic features of pigmented Bowen's disease (BD), which could be a mimic of various pigmented skin lesions. A 79-year-old Japanese woman presented with a 3-year history of brown-black macule on her right upper arm without symptom. Dermoscopic examination demonstrated irregular flossy streaks, irregular brown dots/globules, blue-whitish regression ...
BACKGROUND There is limited data on dermoscopic features of basal cell carcinomas (BCCs). We evaluated the presence of dermoscopic features in superficial (sBCCs), nodular (nBCCs), pigmented and non-pigmented BCCs in order to evaluate the role of dermoscopy in the diagnosis of different subtypes of BCCs. PATIENTS AND METHODS We conducted a retrospective study to evaluate the presence of dermo...
Title of Document: INTENSE LASER ACCELERATION OF QUASI-MONOENERGETIC PROTONS Tung-Chang Liu, Doctor of Philosophy, 2013 Directed By: Professor Chuan S Liu, Physics By irradiating an ultra-thin overdense foil with an intense circularly polarized laser beam, the laser radiation pressure can push the foil forward. This scheme, laser radiation pressure acceleration, is one of the most actively stud...
Carbon nanotube yarns are micron-scale fibers comprised by tens of thousands of carbon nanotubes in their cross section and exhibiting piezoresistive characteristics that can be tapped to sense strain. This paper presents the details of novel foil strain gauge sensor configurations comprising carbon nanotube yarn as the piezoresistive sensing element. The foil strain gauge sensors are designed ...
It is interesting to imagine what would happen when a mixture of soft-boiled eggs and stones is deformed together. A foil made of pure Ti is stronger than that made of Cu. When a composite Cu/Ti foil deforms, the harder Ti will penetrate into the softer Cu in the convex shapes according to previously reported results. In this paper, we describe the fabrication of multilayer Cu/Ti foils by the r...
Cutaneous invasive pigmented squamous cell carcinoma (SCC) is rare. There have previously been only a few case reports or small case series in the English literature [1-13]. In the largest published study there were five cases of pigmented invasive SCC in 46,791 archived cases of invasive SCC (approximately 0.01%) [2]. This compares to pigmented SCC in-situ (pigmented Bowen’s disease) in which ...
This paper deals with image processing for automatic analysis of pigmented skin lesions. A special emphasis is put on pigmented networks in epiluminescence microscopy (ELM) images. The purpose of processing images with pigmented skin lesions is the visualisation for education and training as well as for diagnosis support. We use a colour based segmentation applied to the Karhunen-Lo eve transfo...
BACKGROUND Hidrocystomas are benign tumors of apocrine or eccrine epithelium. They most commonly occur on the head and neck, especially periorbitally. Albeit rare, these adnexal tumors may present as pigmented lesions. PURPOSE To describe a patient with a pigmented eccrine hidrocystoma of his nose and to review the features of other individuals with pigmented hidrocystoma of the nasal epithel...
