The possibility of discerning extensive air showers initiated by ultra-high energy (UHE) photons from those induced by hadrons is studied. Two effects characteristic only for UHE photons are taken into account: LPM effect and photon conversion/cascading in the geomagnetic field. First conclusions about the possibility of identification of photons in the UHE cosmic-ray spectrum are presented and...

We focus on the problem of linking event mentions in cricket match reports to instances from temporal commentary data. The problem is challenging because depending on the event type, event mentions could be linked to a single data instance, or to a set of instances. The complexity of the natural language in the reports along with a lack of canonical names or verbose descriptions of the data ins...

In this paper we present a robust and efficient method to overcome the negative effects of occlusion in the tracking process of multiple agents. The proposed approach is based on the matching of multiple trajectories from multiple views using spatial and temporal information. These trajectories are represented as consecutive points of a joint ground plane in the world coordinate system that bel...

high intensity workout provokes damage in muscles with an effect on muscle physiology and function. today, serum levels of creatine and aspartate aminotransferase are widely used as biochemical markers of muscle damage in order to determine the functional status of muscle tissues in both pathological and physiological conditions. this study investigated the effect of a futsal match on some bioc...

We study the achievable rate region and optimal power allocation for broadcast channels (BC) under orthogonal access schemes. The channel follows a block fading model with channel side information (CSI) perfectly known at the receiver but not at the transmitter. The region boundary is determined by finding the optimal power allocation associated with all boundary points. For the two-user case, ...
