OBJECTIVE To identify factors related to increased or decreased risk of thromboembolism (TE) in patients with high-grade glioma. DESIGN We performed a retrospective analysis of 64 patients enrolled in two prospective clinical trials of chemotherapy and radiation therapy for newly diagnosed high-grade glioma. MATERIAL AND METHODS The 64 patients were 18 years of age or older and had histolog...
Introduction: Sn decays to Te with a half-life of 0.235 Myrs and is a possible short-lived chronometer for early solar system development. Sn can only be produced in significant amounts by the r-process, which is thought to take place in a supernova environment. The discovery of Te excesses that correlate with Sn/Te in meteorites would thus provide confirmation of the theory that a supernova in...
We demonstrate that the atom chain structure of Te allows it to be exfoliated as ultra-thin flakes and nanowires. Atomic force microscopy of exfoliated Te shows that thicknesses of 1-2 nm and widths below 100 nm can be exfoliated with this method. The Raman modes of exfoliated Te match those of bulk Te, with a slight shift (4 cm-1) due to a hardening of the A1 and E modes. Polarized Raman spect...
