The realization that the total energy of GRBs is related to their jet break angles suggests a similar relation between the peak luminosity, L, and the jet break angles, L ∝ θ. Such a relation implies that the GRB luminosity function determines the angular distribution. We re-derive the GRB luminosity function using the BATSE peak flux distribution and compare the predicted distribution with the...
We investigated the physical and thermal properties of 65 Cybele, one of the largest main-belt asteroids. Based on published and recently obtained thermal infrared observations, including ISO measurements, we derived through thermophysical modelling (TPM) a size of 302×290×232 km (± 4%) and an geometric visible albedo of 0.050±0.005. Our model of a regolith covered surface with low thermal iner...
Purpose: The evaluation of plasma testing for the EGFR resistance mutation T790M in NSCLC patients has not been broadly explored. We investigated the detection of EGFR activating and T790M mutations in matched tumor tissue and plasma, mostly from patients with acquired resistance to first-generation EGFR inhibitors. Experimental Design: Samples were obtained from two studies, an observational s...
This paper investigates the directional beaming of metallic subwavelength slits surrounded by dielectric gratings. The design structure for light was formulated as an optimization problem far-field angular transmission. A vertical mode expansion method developed to solve diffraction problem, which then integrated into a genetic algorithm and active set obtain optimal result. By using proposed t...
