We report the first observation of the decay B + → χ c0 K + using 21.3 fb −1 of data collected by the Belle detector at the Υ(4S) resonance. The preliminary result for the branching fraction is B(B + → χ c0 K +) = (8.0 +2.7 −2.4 ± 1.0 ± 1.1) × 10 −4 where the first error is statistical, the second is systematic, and the third comes from the uncertainty in(More)
Double Star Program (DSP) aims to investigate the trigger mechanism and physical models of geomagnetic storms and substorms. The DSP involves two satellites: the equatorial satellite of DSP (TC-1 in China) and the polar satellite of DSP (TC-2 in China). On board the two satellites of TC-1 and TC-2, there are four kinds of particle instruments developed by(More)
Charge trapping and wearout characteristics of self-aligned enhancement-mode GaAs nMOSFETs with silicon interface passivation layer and HfO<sub>2</sub> gate oxide are systematically investigated at various time scales (from micro-seconds to seconds). Unlike high-kappa on silicon devices, both bulk trapping and interface trapping affect the PBTI (positive(More)
The Belle detector was designed and constructed to carry out quantitative studies of rare B-meson decay modes with very small branching fractions using an asymmetric e þ e À collider operating at the U(4S) resonance, the KEK-B-factory. Such studies require data samples containing B10 7 B-meson decays. The Belle detector is configured around a 1:5 T(More)
The Data Driven Design Optimization Methodology (DDDOM) is a Dynamic Data Driven Application System (DDDAS) developed for engineering design optimization. The DDDOM synergizes experiment and simulation in a concurrent integrated software system to achieve better designs in a shorter time. The data obtained from experiment and simulation dynamically guide(More)
Acute cerebral hemorrhage (ACH) is an important clinical problem that is often monitored and studied with expensive devices such as computed tomography, magnetic resonance imaging, and positron emission tomography. These devices are not readily available in economically underdeveloped regions of the world, emergency departments, and emergency zones. We have(More)
