This paper develops a framework to test whether discrete-valued irregularly-spaced financial transactions data follow a subordinated Markov process. For that purpose, we consider a specific optional sampling in which a continuous-time Markov process is observed only when it crosses some discrete level. This framework is convenient for it accommodates not only the irregular spacing of transactio...

Selenocysteine (Sec) is the 21st amino acid in translation. Sec tRNA (tRNA(Sec)) has an anticodon complementary to the UGA codon. We solved the crystal structure of human tRNA(Sec). tRNA(Sec) has a 9-bp acceptor stem and a 4-bp T stem, in contrast with the 7-bp acceptor stem and the 5-bp T stem in the canonical tRNAs. The acceptor stem is kinked between the U6:U67 and G7:C66 base pairs, leading...

The effect of traits and the interaction genotype × environment (GE) is one major challenges in detecting genotypes with outstanding performance stability through various stresses years. objective this study was to identify genetic influence wheat, under different environmental stress. trials were carried out two consecutive seasons three treatments (optimal irrigation, limited heat stress), to...

The genotype × environment interaction has a direct effect on genotypes stability and adaptability in different environmental conditions . In this sense, plant breeders look for genotypes that have general adaptability, or they look for genotypes that have specific adaptability for specific environments. In this regard, 20 chickpea genotypes were used in a randomized complete block design with ...
