We introduce the notion of ideal, prime ideal, lter, fuzzy ideal, fuzzy prime ideal, fuzzy lter of ordered $Gamma$-semiring and study their properties and relations between them. We characterize the prime ideals and lters of ordered $Gamma$-semiring with respect to fuzzy ideals and fuzzy l- ters respectively.

The aim of this short note is to introduce the concepts of prime and semiprime ideals in ordered AG-groupoids with left identity. These concepts are related to the concepts of quasi-prime and quasi-semiprime ideals, play an important role in studying the structure of ordered AG-groupoids, so it seems to be interesting to study them.

The spike protein VP4 is a key component of the membrane penetration apparatus of rotavirus, a nonenveloped virus that causes childhood gastroenteritis. Trypsin cleavage of VP4 produces a fragment, VP5*, with a potential membrane interaction region, and primes rotavirus for cell entry. During entry, the part of VP5* that protrudes from the virus folds back on itself and reorganizes from a local...

Previous work has used entry point search (EP search) to accelerate raytracing by avoiding redundant traversal of nodes in a KD tree. EP search works by identifying a node which may be used as a starting point for tracing a particular group of coherent rays, thus bypassing all nodes above it. This is most effective when all rays can be shown to be occluded, since a leaf or low inner node can of...

The idea of automatic generation of data entry forms based on data relational models is a common and known idea that has been discussed day by day more than before according to the popularity of agile methods in software development accompanying development of programming tools. One of the requirements of the automation methods, whether in commercial products or the relevant research projects, ...

For certain database tasks that require great exibility, some people are turning to a new kind of data representation in which the database is not constrained by a schema. Instead, each component of the database carries its own description, which is independent of other components. Systems like ACeDB, which has become very popular with biologists, and the recent Tsimmis proposal for data integr...
