We present a wide dataset of gamma-ray, X-ray, UVOIR, and radio observations the Swift GRB100814A. At end slow decline phase X-ray optical afterglow, this burst shows sudden prominent rebrightening in band only, followed by fast decay both bands. The also chromatic evolution. Such puzzling behaviour cannot be explained single component model. discuss other possible interpretations, we find that model incorporates long-lived reverse shock forward fits temporal spectral properties GRB100814A best.
As Wi-Fi access points (APs) are deployed more densely, the cross-technology interference (CTI) from is becoming a real threat to co-existing low-power IoT protocols such as BLE. In this work, we pay attention beacons that take substantial amount of airtime in 2.4 GHz Industrial Scientific Medical (ISM) band. We develop B-hop, standard-compliant framework adjusts BLE frequency hopping avoid expected time domain. B-hop operates on master devices where and co-located, it requires no...
