The latter theorem shows the relation of the (coefficients of the realized) elliptic curves corresponding to two isogenous torus C/Z + τZ and C/Z + 2τZ. So in general this theorem is referred as the isogeny formula for the Jacobi theta constants. Any way these two theorems are telling us a very interesting story concerned with AGM, periods of algebraic varieties, hypergeometric functions and mo...

The activity of the N-terminal activation function AF-1 of RAR alpha1 is abrogated upon mutation of a phosphorylatable serine residue (Ser-77). Recombinant RAR alpha was phosphorylated by a variety of proline-directed protein kinases in vitro. However, only the coexpression of cdk7 stimulated Ser-77 phosphorylation in vivo and enhanced transactivation by RAR alpha, but not by a S77A RAR mutant....

Ascochyta blight (caused by rabiei) is an important disease of chickpea. Mating type distribution, genetic diversity and population structure A. rabiei isolates from western Iran, using specific matting primers, ISSR SSR molecular markers. Two mating types were identified, with the 57% belonging to MAT1-1. Ten markers produced 78 polymorphic bands average polymorphism information content (PIC) ...

The order Chaetothyriales (Pezizomycotina, Ascomycetes) harbours obligatorily melanised fungi and includes numerous etiologic agents of chromoblastomycosis, phaeohyphomycosis and other diseases of vertebrate hosts. Diseases range from mild cutaneous to fatal cerebral or disseminated infections and affect humans and cold-blooded animals globally. In addition, Chaetothyriales comprise species wit...

The genus Phyllosticta occurs worldwide, and contains numerous plant pathogenic, endophytic and saprobic species. Phyllosticta citricarpa is the causal agent of Citrus Black Spot disease (CBS), affecting fruits and leaves of several citrus hosts (Rutaceae), and can also be isolated from asymptomatic citrus tissues. Citrus Black Spot occurs in citrus-growing regions with warm summer rainfall cli...

Friedrich Hebbel wrote his play Cyges und sein Ring between 1853 and 1854, hence only a few years after the March Revolution of 1848. He prefaced the play with a brief note that he apparently found necessary for the reader's orientation. "The action," he indicated, "is prehistorical and mythic; it takes place within a temporal span of twice twenty-four hours." 1 This sentence offers information...
