چکیده
The paper presents a simple format for typed logics with states by adding a function for register update to standard typed lambda calculus. It is shown that universal validity of equality for this extended language is decidable (extending a well-known result of Friedman for typed lambda calculus). This system is next extended to a full edged typed dynamic logic, and it is illustrated how the resulting format allows for very simple and intuitive representations of dynamic semantics for natural language and denotational semantics for imperative programming. The proposal is compared with some alternative approaches to formulating typed versions of dynamic logics. Note: Work carried out under project P4303; paper accepted for publication in the Journal of the IGPL.

Isoform diversity of the inositol trisphosphate receptor in cell types of mouse origin.
Previous reports suggested the expression of four or five different Ins(1,4,5)P3 receptor [Ins(1,4,5)P3R] isoforms in mouse cells [Ross, Danoff, Schell, Snyder and Ullrich (1992) Proc. Natl. Acad. Sci. U.S.A. 89, 4265-4269; De Smedt, Missiaen, Parys, Bootman, Mertens, Van Den Bosch and Casteels (1994) J. Biol. Chem. 269, 21691-21698]. To explore this diversity further, we have isolated and sequ...

R m p x p y p f p Cramer 1 (1) ABSTRACT One of the major tasks in the evaluation process of remotely sensed data is the determination of the exterior orientation to relate the recorded data to a geodetic reference coordinate frame. This process is called georeferencing and is very close to the concept of inverse photogrammetry realized indirect via the use of ground control. With the availabili...

A dual-bring of a feature-logic and a concatenation-logic is proposed, in which syntactic categorial types \live in" feature terms, in contrast to current bring, in which feature-terms \live in" types. The dual-bring contains also arrow-introduction rules for hypothetical reasoning. It is used to explain some \privileged features" in HPSG and their non-uniication manipulation. Note: Paper prese...
متن کاملEffect of sub lethal concentration of imidacloprid on proximate body composition of Labeo rohita
Randomly selected 320 fingerling of Labeo rohita were collected from Faheem fish farm, Mattital Road, Multan. Groups of 40 fish each were exposed to subleathal concentration of imidacloprid (120 mg L-1) under short (2, 4 and 8 days) and long term (16, 32 and 64 days) conditions to access the effect of this most extensively used pesticide on the body composition parameters of economically most i...
متن کاملD-myo-Inositol 1,4,5,6-tetrakisphosphate produced in human intestinal epithelial cells in response to Salmonella invasion inhibits phosphoinositide 3-kinase signaling pathways.
Several inositol-containing compounds play key roles in receptor-mediated cell signaling events. Here, we describe a function for a specific inositol polyphosphate, D-myo-inositol 1,4,5,6-tetrakisphosphate [Ins(1,4,5,6)P4], that is produced acutely in response to a receptor-independent process. Thus, infection of intestinal epithelial cells with the enteric pathogen Salmonella, but not with oth...
