this study aimed to investigate the relationship between race horse breed and the frequency of limb injuries through the time of training and racing. the study population consisted of 4042 thoroughbred and 2553 arabian horses raced at warsaw race track, from 2000 to 2008. among these horses, 94 thoroughbreds and 32 arabians had different limb injuries. based on the achieved results, it is possi...

We propose a short period undulator based on the electromagnetic field pattern in THz-driven split ring resonator structure. An analytical model is developed that allows us to assess key performance parameters of and estimate emitted radiation spectrum. Different geometric configurations are compared detail using numerical simulations. A 100 MeV electron bunch with 5 pC charge shown emit narrow...

Abstract Ring resonator is an essential element in silicon integrated circuit, it widely used as filter, wavelength multiplexer and switch single-mode operation regime. As the rapid development of mode division multiplexing (MDM) technique, ring that can process multi-mode signals simultaneously uniformly highly desired. However, severe modal dispersion makes identical transmission for differen...
