DESCRIPTION:Speakers: TAKAMI\, Hajime (M)\nThe origin of ultra-high-energy
  (UHE) cosmic rays (CRs) is still unknown and one of the biggest mysteries
  in modern astrophysics. The uncertainty of their composition makes this p
 roblem more complicated. If protons are dominant in UHECRs and are produce
 d by phenomena related to astrophysical jets or outflows\, there are few s
 teady source candidates in local Universe which have luminosities enough t
 o accelerate protons up to 10^{20} eV via statistical particle acceleratio
 n mechanisms. Since the few steady sources are difficult to reproduce isot
 ropy observed by recent UHECR experiments\, promising source candidates ar
 e astrophysical transients such as flares of active galactic nuclei and ga
 mma-ray bursts. In this presentation we discuss how evidence of transient 
 sources can be found and how future UHECR experiments can constrain transi
 ent source population of UHE protons.\n\nhttp://indico.cern.ch/contributio
