An amoeba is the image of a subvariety an algebraic torus under logarithmic moment map. We consider some qualitative aspects amoebas, establishing results and posing problems for further study. These include determining dimension amoeba, describing as semi-algebraic set, identifying varieties whose amoebas are finite intersection hypersurfaces. show that not full such if its variety nondegenera...

This paper 1 reports a recent development on the Amoeba distributed operating system | the ADE emulation system, which aims at making Amoeba fully compatible with the Unix (POSIX) operating system so that existing Unix applications can directly run on the Amoeba system and immediately beneet from the use of the Amoeba multiple processors.

Amoeba is a capability-based distributed operating system designed for high performance interactions between clients and servers using the well-known RPC model. The paper starts out by describing the architecture of the Amoeba system, which is typified by specialized components such as workstations, several services, a processor pool, and gateways that connect other Amoeba systems transparently...

BACKGROUND Mycobacterium smegmatis is a rapidly-growing mycobacterium causing rare opportunistic infections in human patients. It is present in soil and water environments where free-living amoeba also reside, but data regarding M. smegmatis-amoeba relationships have been contradictory from mycobacteria destruction to mycobacteria survival. METHODOLOGY/PRINCIPAL FINDINGS Using optic and elect...

AIM A seasonal variation was noted in the incidence of amoeba-like keratitis in Iowa. The level of contamination of amoeba in surface water has been found previously to vary on a monthly basis for Tulsa, Oklahoma, a region with a similar climate. It was hypothesised that this seasonal variation in amoeba-like keratitis correlated with the concentration of amoeba in surface water. METHODS The ...
