Blooming alarm
warning that deadly new strains of tuberculosis, virtually untreatable using the drugs currently available, appear to be spreading across the globe, raising the spectre of a resurgence in a disease which for many generations has laid in the background, seemingly beaten, but which may now make a major comeback as a lethal new pathogen. The new strains are known as extreme drug-resistant TB or XD...
متن کاملBoosting the Late-Blooming Boy
CONTEXT: The indications for use of growth hormone (GH) have broadened with the availability of unlimited recombinant human growth hormone (rhGH). The FDA's approval for use of growth hormone in GH-sufficient patients with idiopathic short stature includes some children with constitutional delay of growth and puberty (CGD), a normal growth pattern variation which includes delayed puberty and pr...
متن کاملBoundary-dominant flower blooming simulation
This paper presents a new simulation method for flower blossom, which is based on a biological observation that flower opening is caused by a boundary-dominant morphological transition in a curved lamina. We use an elastic triangular mesh to represent a flower petal and adopt the in-plane expansion to induce the global bending. Out-of-plane curl plays an auxiliary role in reducing the curvature...
متن کاملThermal-Blooming Laboratory Experiments
• We conducted a multiphase series of laboratory experiments to explore the adaptive optics compensation of a laser beam distorted by strong thermal blooming. Our experimental approach was to create on a small, low-power beam the same phase distortion that would be experienced by a large, high-power beam propagating through the atmosphere and to apply phase compensation via deformable mirrors. ...
متن کاملScaled Atmospheric Blooming Experiments (SABLE)
II The SABLE field experiments investigated the use of phase-conjugate adaptive optics to compensate for strong thermal blooming and turbulence. The experiments, conducted at the TRW Capistrano Test Site in southern California over horizontal paths of 100 and 400 m, were designed to explore issues related to the propagation ofhigh-power lasers from the ground to space. The laser used in the exp...
