Questions whether or not two grammars belonging to a family of grammars generate the same language have extensively been studied in the literature. These problems are called equivalence problems and if there exists an algorithm which for each pair of grammars of this family gives an answer to this question then the equivalence problem for this family of grammars is said to be decidable. Otherwi...

BACKGROUND T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL) and are often thought to represent a spectrum of a single disease. The malignant cells in T-ALL and T-LL are morphologically indistinguishable, and they share the expression of common cell surface antigens and cytogenetic characteristics. However, despite these similarities, differences in the clinic...

Living Lab (LL) has been used as a milieu as well as methodology for open innovation. However, the impression of LL as a research methodology among academia is still blurring. The LL carries many elements of design science research paradigm such as innovation, artifact, evaluation, design principles, etc. however it still needs conceptual underpinning to proclaim it as a valid Design Science Re...

A three-month culture experiment was designed to assess the effects of photoperiod and feeding regime on growth, feed utilization, food anticipatory activity (FAA) juvenile rainbow trout. The included two photoperiods: 24L:0D (LL) 12L:12D (LD); three regimes: random (R), mid-dark stage (D), mid-light (L). total six treatment groups (R-LL, D-LL, L-LL, R-LD, D-LD, L-LD) were defined. experimental...

Interleukin-8 (IL-8), a neutrophil-activatbig cytokine, also activates certain T cell functions such as chemotaxis. We additionally find (n 6) that recombinant (rIL-8; 1-100 ng/ml), when added to 24 h culture of human CD4 T cells, suppressed the spontaneous production of IL-4 (50-85%). Steady state production of IL-4 was typically around 30 pg/nil, determined by use of a solidphase immunoabsorb...

Adult neurogenesis represents a unique form of plasticity in the dentate gyrus requiring the presence of long-lived neural stem cells (LL-NSCs). However, the embryonic origin of these LL-NSCs remains unclear. The prevailing model assumes that the dentate neuroepithelium throughout the longitudinal axis of the hippocampus generates both the LL-NSCs and embryonically produced granule neurons. Her...

This paper is an overview of existing applications of Linear Logic LL to issues of computation After a substantial introduction to LL it discusses the implications of LL to functional programming logic programming concurrent and object oriented programming and some other applications of LL like semantics of negation in LP non monotonic issues in AI planning etc Although the overview covers pret...
