The Replication Logic is a set of protocols, mechanisms and services that allow a CORBA system to handle object replication. In this paper we present a specific implementation of a Replication Logic, namely Interoperable Replication Logic (IRL), which exhibits nice properties like non-intrusion (i.e., the replication logic is built “above” the ORB) and interoperability (i.e., a client can resid...

Current Grid Security Infrastructure using PKI based on SSO. Trust is hard to establish in a service-oriented grid architecture because of the need to support end user SSO and dynamic transient service. Open Grid Service (OGS) Security Infrastructure in Global Grid Forum will extend use of Grid system or services up to business area using XML Web Service security technology. This paper describe...

By JOHN A. CAVINS, SHINPEI KASAKURA, E. DONNALL THOMAS AND JOSEPH W. FERREBEE D OGS lethally exposed to general radiation usually make uneventful recoveries if given prompt infusions of a few billion autologous marrow cells.1’2 Cells for these infusions can be preserved indefinitely at bow temperature in glycerol. ’4 Recent studies suggest that dimethyl-sulphoxide may be preferable to glycerol ...

This letter studies a placement method of optical ground stations (OGSs) to realize site diversity in satellite-to-ground communications under cloud attenuation. Using meteorological ERA-Interim database, the monthly average attenuation over Japan during 2018–2022 is calculated. Based on obtained results, set candidates for OGS proposed, including places with lowest attenuation, major cities, a...

Abstract. Ammonia (NH3) in the atmosphere affects both environment and human health. It is therefore increasingly recognised by policy makers as an important air pollutant that needs to be mitigated, though it still remains unregulated many countries. In order understand effectiveness of abatement strategies, routine NH3 monitoring required. Current reference protocols, first developed 1990s, u...

Oligodendrocytes (OGs) assemble the myelin sheath around axons in the central nervous system. Specification of cells into the OG lineage is largely the result of interplay between bone morphogenetic protein, sonic hedgehog and Notch signaling pathways, which regulate expression of transcription factors (TFs) dictating spatial and temporal aspects of oligodendrogenesis. Many of these TFs and oth...

The Nigerian Universities rely on weak and unreliable fossil-based electric grids with diesel engine generators (DEG) as a backup. However, there is potential to light up the campuses using power systems derived from primary renewable (RPS) like wind turbine (WT) solar photovoltaic (PV), that can be or off-grid improve energy mix duration reliably. This study presents comparative analysis of op...
