A theoretical study of the structural and electronic properties of the chloride ion and water molecules in the first hydration shell is presented. The calculations are performed on an ensemble of configurations obtained from molecular dynamics simulations of a single chloride ion in bulk water. The simulations utilize the polarizable AMOEBA force field for trajectory generation and MP2-level ca...

INTRODUCTION Ulcerative colitis (UC) is a common disease with a chronic and relapsing presentation requiring regular clinical follow up. Epidemiological and microbiologic studies suggest that enteropathogenic microorganisms play a substantial role in the clinical presentation and extent of inflammatory bowel disease. GOAL To evaluate the presence of intestinal infections by Entamoeba hystolit...

We present an extension of the polarizable quantum mechanical (QM)/AMOEBA approach to enhanced sampling techniques. This is achieved by connecting PLUMED library machinery based on interface Gaussian and Tinker perform QM/AMOEBA molecular dynamics. As application, we study excited state intramolecular proton transfer 3-hydroxyflavone in two solvents: methanol methylcyclohexane. By using a combi...

We prove that if Q is a nw-nep forcing then it cannot add a dominating real. We also show that amoeba forcing cannot be P(X)/I if I is an א1-complete ideal. Furthermore, we generalize the results of [12].

Amoeboid protists are among the most common and abundant microbes in all types of soil habitats. They can be isolated easily using relatively simple methods and most soil samples yield dozens of amoeba species. However, identification of most species is a difficult and challenging task and, in many cases, cannot be conclusive. Identification of amoebae (based on morphological and ultrastructura...

Amoeba is the distributed system developed at the Free University (VU) and Centre for Mathematics and Computer Science (CWI), both in Amsterdam. Throughout the project’s ten-year history, a major concern of the designers has been to combine the research themes of distributed systems, such as high availability, use of parallelism and scalability, with simplicity and high performance. Distributed...

Protozoan and nematode infections of Periplaneta americana in Bulgaria were investigated. Five protozoan and 2 nematode parasites of P. americana were recorded: Endamoeba blattae, Amoeba sp., Lophomonas striata, Nyctotherus ovalis, Balantidium blattarum, Hammerschmidtiella diesingi and Leidynema appendiculatum. Parasite prevalence varied from 1,6% for Amoeba sp. to 32,8% for nematodes. Biometri...
