We investigate the strong stability preserving (SSP) property of two-step Runge– Kutta (TSRK) methods. We prove that all SSP TSRK methods belong to a particularly simple subclass of TSRK methods, in which stages from the previous step are not used. We derive simple order conditions for this subclass. Whereas explicit SSP Runge–Kutta methods have order at most four, we prove that explicit SSP TS...

Angiosperm stigmas have long been known to exhibit high levels of peroxidase activity when they are mature and most receptive to pollen but the biological function of stigma peroxidases is not known. A novel stigma-specific class III peroxidase gene, SSP (stigma-specific peroxidase) expressed exclusively in the stigmas of Senecio squalidus L. (Asteraceae) has recently been identified. Expressio...

The notion of partial deduction known from logic programming is deened in the framework of Structural Synthesis of Programs (SSP). Partial deduction for computability statements in SSP is deened. Completeness and correctness of partial deduction in the framework of SSP are proven. Several tactics and stopping criteria are suggested.

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

The notion of partial deduction known from logic programming is deened in the framework of Structural Synthesis of Programs (SSP). Partial deduction for unconditional computability statements in SSP is deened. Completeness and correctness of partial deduction in the framework of SSP are proven. Several tactics and stopping criteria are suggested.

Structured sequence processing (SSP) refers to the neurocognitive mechanisms used to learn sequential patterns in the environment. SSP ability seems to be important for language (Conway, Bauernschmidt, Huang, & Pisoni, 2010); however, there are few neural studies showing an empirical connection between SSP and language. The purpose of this study was to investigate the association between SSP an...

The teosintes, the closest wild relatives of maize, are important resources for the study of maize genetics and evolution and for plant breeding. We genotyped 237 individual teosinte plants for 93 microsatellites. Phylogenetic relationships among species and subspecific taxa were largely consistent with prior analyses for other types of molecular markers. Plants of all species formed monophylet...

The envelope glycoprotein of the arenaviruses (GP-C) is unusual in that the mature complex retains the cleaved, 58-amino-acid signal peptide. Association of this stable signal peptide (SSP) has been shown to be essential for intracellular trafficking and proteolytic maturation of the GP-C complex. We identify here a specific and previously unrecognized role of SSP in pH-dependent membrane fusio...

The YODA (YDA) mitogen-activated protein kinase pathway promotes elongation of the Arabidopsis zygote and development of its basal daughter cell into the extra-embryonic suspensor. Here, we show that the interleukin-1 receptor-associated kinase (IRAK)/Pelle-like kinase gene SHORT SUSPENSOR (SSP) regulates this pathway through a previously unknown parent-of-origin effect. SSP transcripts are pro...
