Oasis is a memory-based storage system designed to support collaborative mobile computing applications. These applications require peer-to-peer and client-server interactions in conditions of less than ideal network connectivity. The architecture is based on a memory model where the address space is logically partitioned into regions used for sharing. Mobile units may disconnect from the backbo...

When counting isomers with a given number of atoms one usually assumes that we want to count (connected) molecules. In this note we present a method that can be used for counting disconnected structures if counts of connected structures are given. The method can be used also in the reverse direction. If the numbers of all structures are known, the number of connected structures can be readily d...

Disconnected pancreatic duct syndrome (DPDS) is characterised by disruption of the main pancreatic duct with a loss of continuity between the pancreatic duct and the gastrointestinal tract caused by ductal necrosis after severe acute necrotising pancreatitis treated medically, by percutaneous drainage, or necrosectomy. There are no clear epidemiological data on the real incidence of DPDS; appro...

Very often in analysis, one focuses on connected spaces. This is certainly not always the case, and in particular there are many interesting matters related to Cantor sets. Here we are more concerned with a type of complementary situation. As a basic scenario, suppose that U is an open set in Rn and that E is a closed set contained in the boundary of U such that for every x ∈ U and r > 0 there ...

During solar eruptions, many closed magnetic flux ropes are ejected into interplanetary space, which contribute to the heliospheric field and have important space weather effect because of their coherent field. Therefore, understanding evolution these in is important. In this paper, we examined all plasma data measured 1997 by Wind spacecraft identified 621 reconnection exhausts. Of events, 31 ...

For a connected graph G = (V,E), a subset U ⊆ V is called a disconnected cut if U disconnects the graph and the subgraph induced by U is disconnected as well. A natural condition is to impose that for any u ∈ U the subgraph induced by (V \U)∪{u} is connected. In that case U is called a minimal disconnected cut. We show that the problem of testing whether a graph has a minimal disconnected cut i...

This paper initiates the study of sets in Euclidean space R (n ≥ 2) that are defined in terms of the dimensions of their elements. Specifically, given an interval I ⊆ [0, 1], we are interested in the connectivity properties of the set DIM consisting of all points in R whose (constructive Hausdorff) dimensions lie in the interval I. It is easy to see that the sets DIM and DIM(n−1,n] are totally ...

The space of four dimensional string and M theory vacua with non-Abelian gauge symmetry, chiral fermions and unbroken supersymmetry beyond the electroweak scale appears to be a disconnected space whose different components represent distinct universality classes of vacua. Calculating statistical distributions of physical observables a la Douglas therefore requires that the distinct components a...
