In this paper, we present several mean-reversion jump di usion models to describe energy commodity spot prices. We incorporate multiple jumps, regime-switching and stochastic volatility in these models. Prices of various energy commodity derivatives are obtained under each model. We show how the electricity derivatives can be used to evaluate generation and transmission capacity. We also show f...

Comprehensive rehabilitation is a concept developed in order to limit the physiopathologic and psychosocial consequences of the cardiac events and aims at limiting the risk of infract and of sudden death, at improving the cardiac symptomathology, at delaying or determining the reversion of the atherosclerotic process and at reintegrating the cardiac patients within their family and professional...

The nucleic acids ot isolated plant tissues were first shown to be affected by plant growth regulators by Silberger and Skoog (1953). They showed that indoleacetic acid treatment would increase the level of ribonucleic acid (RNA) and deoxyribonucleic acid in tobacco pith tissue. Recently, experiments with excised stems of cucumber seedlings (West, Hanson and Key, 1960), and excised cotton cotyl...

Little is known about quality control of proteins that aberrantly or persistently engage the endoplasmic reticulum (ER)-localized translocon en route to membrane localization or the secretory pathway. Hrd1 and Doa10, the primary ubiquitin ligases that function in ER-associated degradation (ERAD) in yeast, target distinct subsets of misfolded or otherwise abnormal proteins based primarily on deg...

Rosmarinus officinalis (Lamiaceae) possesses antioxidant activity and hepatoprotective effects, and so may provide a possible therapeutic alternative for chronic liver disease. The effect produced by a methanolic extract of Rosmarinus officinalis on CCl(4)-induced liver cirrhosis in rats was investigated using both prevention and reversion models. Over the course of the development of cirrhosis...

Ultraviolet irradiation of Escherichia coli polA(-) cells reduces their capacity to support the growth of T4 phage. There is no additional loss of capacity observed in pol tsA(-)recA(-) double mutants at the nonpermissive temperature. The reversion frequency of a T4 rII mutant after ultraviolet irradiation is not changed by the absence of host deoxyribonucleic acid polymerase I.

The paper describes some of the characteristic properties of an altered form of pyruvate kinase from a mutant of Saccharomyces cerevisiae. The partially purified enzyme does not require fructose 1,6-bisphosphate for activity but is stabilised in its presence both at low and at high temperatures. The enzyme displays in the absence of fructose 1,6-bisphosphate hyperbolic kinetics with phosphoenol...

PARP inhibition is synthetic lethal with defective DNA repair via homologous recombination. Phase I and II clinical trials show that PARP inhibitors are effective at well-tolerated doses and have antitumor activity for BRCA1- and BRCA2-associated cancers. However, not all patients respond equally well and tumors may eventually become resistant. Thus far, the only resistance mechanism that has b...

Fifteen days after thyroidectomy, the pituitary acidophils of rats were definitely deprived of their large granules , about 350mƒÊ in diameter each, and in due succession, they displayed the changes characterized by the features of "thyroidectomy cells"(TXcells). When these rats were given a single or three injections of thyroxine, 50mg/rat, most of TX-cells might revert to their original acido...

The present paper characterizes the mean-reverting behavior of six ASEAN markets – Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam – using an autoregressive exponential GARCH-in mean model and daily data from August 2000 to May 2010. The results indicate fast speed of mean-reversion in the returns of these markets but with quite distinct patterns of return dynamics. The e...
