We derive a new set of WDVV equations for N = 2 SYM in which the renormalization scale Λ is identified with the distinguished modulus which naturally arises in topological field theories.

We discuss the interplay between IR and UV divergences in vacuum configurations with open and unoriented strings. We establish a general one-to-one correspondence between anomalies and R-R tadpoles associated to sectors with non-trivial Witten index. The result does not require any supersymmetry to be preserved by the configuration. Under very mild conditions of supersymmetry, a similar corresp...

Using a characterization of stable models of logic programs P as satisfying valuations of a suitably chosen propositional theory, called the set of reduced defining equations rΦP , we show that the finitary character of that theory rΦP is equivalent to a certain continuity property of the Gelfond-Lifschitz operator GLP associated with the program P . The introduction of the formula rΦP leads to...

A new method is presented to obtain the anomalous dimension in the solution of the Barenblatt’s equation. The result is the same as that in the renormalization group (RG) approach. It gives us insight on the perturbative solution of the Barenblatt’s equation in the RG approach. Based on this discussion, an improvement is made to take into account, in more complete way, the nonlinear effect, whi...

The dynamic nature of a mobile ad hoc network (MANET) may result in a cluster of nodes being isolated from the rest of the network, especially when deployed in a terrain with blockages. To provide connectivity between the partitions of an ad hoc network that might occur due to mobility, a ‘range extension’ network can be employed. Such a network might consist of airborne communication platforms...

The residential gateway is a device that has become an integral part of home networking equipment. Discovering a Location Information Server (LIS) is a necessary part of acquiring location information for location-based services. However, discovering a LIS when a residential gateway is present poses a configuration challenge, requiring a method that is able to work around the obstacle presented...

The technical guideline TR-03109 divides between the roles of the SMGW technician and the Gateway administrator whereas the Gateway administrator gains full access to the SMGW and the service technician has only very limited access rights. In many scenarios the service technician will also need full access to the Smart Meter Gateway which means that he must be able to change its role. Federated...

In a large class of sensor network deployments, a small subset of the sensors covering the sensor field is equipped with special communications capability to communicate with operators outside the sensor field. These sensors play the role of gateways for off-field communication in the sense that all communications toor out of the field is through these nodes, and the other non-gateway nodes are...

Sequence of drug use was examined in a secondary analysis of two samples of serious drug users: one of 152 men and one of 133 women. The proportions of drug users following specified patterns of drug use onset were compared to proportions obtained in previous research in samples of high school youth, and serious drug users. The serious drug users were substantially different from high school sa...
