The extremogram is an asymptotic correlogram for extreme events constructed from a regularly varying stationary sequence. In this paper, we define a frequency domain analog of the correlogram: a periodogram generated from a suitable sequence of indicator functions of rare events. We derive basic properties of the periodogram such as the asymptotic independence at the Fourier frequencies and use...

zebra fish were exposed to environmentally relevant concentration of pesticides and metals fora period of 14 days. the individual and the combined toxicity of pesticides and metals were studied. damage caused to the dna and induction of mutation in the gadd45β gene was investigated in this study. the present investigation revealed that exposure of zebra fish to pesticides and metals induced dna...

The basic chemical structure of most prostate specific membrane antigen (PSMA) inhibitors which are now in pre-clinical and clinical studies is Glu-Ureido-based peptides. Synthesis of urea-based PSMA inhibitors includes two steps: 1- isocyanate intermediate formation and 2- urea bond formation. In current methods, isocyanate is formed in liquid phase and then reacts with amine existing in liqui...
