Universal access to the WWW has made security a top issue. New problems have arisen in areas such as legally mandated privacy policies and protecting intellectual property. Collaborative arrangements need to be created and ended, rapidly. Systems architectures have become far more complex, so data requires protection in documents, messaging systems, and application servers. Most crucially, ther...

Extended cubical sets (with connections and interchanges) are presheaves on a ground category, the extended cubical site K, corresponding to the (augmented) simplicial site, the category of finite ordinals. We prove here that K has characterisations similar to the classical ones for the simplicial analogue, by generators and relations, or by the existence of a universal symmetric cubical monoid...

We construct gauge invariant operators in non-commutative gauge theories which in the IR reduce to the usual operators of ordinary field theories (e.g. TrF 2). We show that in the deep UV the two-point functions of these operators admit a universal exponential behavior which fit neatly with the dual supergravity results. We also consider the ratio between n-point functions and the two-point fun...

Information about soil properties helps the farmers to adopt effective and efficient farming practices, which can increase higher yields with optimum usage of farm resources. An attempt has been made in this paper predict using geospatial kriging approaches. This study mainly focuses on predicting pH different methods. Soil dramatically affects many other processes, such as nitrification denitrifi...

We proposed a syntactic format, the panth format, for structured operational semantics in which besides ordinary transitions also predicates, negated predicates, and negat.ed transitions may occur such that if the rules are stratifiable strong bisimulation equivalence is a cOllgruence for all the operators that can be defined within the panik format.. To show that this format is useful we took ...

Recent work on Euler hierarchies of field theory Lagrangians iteratively constructed from their successive equations of motion is briefly reviewed. On the one hand, a certain triality structure is described, relating arbitrary field theories, classical topological field theories – whose classical solutions span topological classes of manifolds – and reparametri-sation invariant theories – gener...

This paper studies gravitational collapse of a complex scalar field at the threshold for black hole formation, assuming that the collapse is spherically symmetric and continuously self-similar. A new solution of the coupled Einstein-scalar field equations is derived, after a small amount of numerical work with ordinary differential equations. The universal scaling and echoing behavior discovere...
