The University of Pretoria’s ATM Lab provides opportunities to investigate and acquire hands-on experience in ATM related technologies and prepares postgraduate students for roles within a high speed networking environment. The ATM Lab will become a more integral part of “high speed network” related research and will also be included in the formal network curriculum. The learning experience not...

The checkpoint kinase ATM is centrally involved in the cellular response to DNA double-strand breaks. However, the mechanism of ATM activation during genotoxic stress is only partially understood. Here we report a direct regulatory linkage between the protein serine-threonine phosphatase 5 (PP5) and ATM. PP5 interacts with ATM in a DNA-damage-inducible manner. Reduced expression of PP5 attenuat...

It is now recognized that a subset of B-cell chronic lymphocytic leukemia (CLL) is familial. The genetic basis of familial CLL is poorly understood, but recently germ line mutations in the Ataxia Telangiectasia (ATM) gene have been proposed to confer susceptibility to CLL. The evidence for this notion is, however, not unequivocal. To examine this proposition further we have screened the ATM gen...

In this paper we propose approaches for shortcutting of IP flows over large ATM networks. With large ATM networks we mean that the single physical ATM network is logically structured into multiple logical ATM subnetworks. Shortcutting across such large, logically structured ATM networks is a technique to avoid network layer processing as much as possible by maximizing the switched path across t...

Abstract: ATM virtual path has recently been paying attention to the effective deployment of IP over ATM. The effective IP service provisioning depends fully on the reliability and optimality of ATM VP layer network because the relationship between IP and ATM VP networks is client and server. In order to guarantee the network survivability of ATM VP layer network and to provide the reliable IP ...

A crucial component of the interaction between ATM’s and the Internet’s Quality of Servcice (QoS) architectures is the efficient mapping of RSVP (Resource reSerVation Protocol) as the Internet’s signalling protocol onto the according ATM mechanisms. In particular, this article focuses on one of the most contrary characteristics of RSVP and ATM signalling. This is the support for heterogeneous r...

This paper uses a unique database to test the effect of ATM surcharges on large versus small banks. Specifically, we examine the impact of ATM surcharges on bank customer incentives to switch accounts, from smaller banks to larger banks, in order to avoid ATM surcharges. We find that ATM surcharges increase the market share of deposits of large banks and decrease the market share of the smaller...

The future development of Air Traffic Management (ATM), set by the ATM 2000+ Strategy, involves a structural revision of ATM processes, a new ATM concept and a system approach for the ATM network. This requires ATM services to go through significant structural, operational and cultural changes that will contribute towards the ATM 2000+ Strategy. Moreover, from a technology viewpoint, future ATM...

The human genetic disorder ataxia-telangiectasia is characterized by immunodeficiency, progressive cerebellar ataxia, radiosensitivity, cell cycle checkpoint defects, and cancer predisposition. The gene product [ataxia-telangiectasia mutation (ATM)] mutated in this syndrome is a component of the DNA damage detection pathway. Loss of ATM function in human and mouse cells causes defects in DNA re...
