This special issue of The European Journal of Control is dedicated to some of the results of the European Community Esprit LTR Project VHS Veri cation of Hybrid Systems It consists of papers dealing with various aspects of one of the case studies treated in the project the Experimental Batch Plant at the university of Dortmund Before presenting the papers themselves it is worthwhile to say some...

In the plumes of Hall thrusters and ion thrusters, high energy neutral atoms are created as a result of the charge exchange interaction between exhaust ions and neutral atoms exiting the discharge region. Proper modeling of fast atoms is important for assessing spacecraft-plume interaction in space as well as facility interactions for ground tests. Many numerical models for Hall thrusters appro...

Optical parameter assignment via Transfer Functions (TF) is the sole interactive part in medical visualization via volume rendering. Being an interactive element of the rendering pipeline, TF specification has very important effects on the quality of volume-rendered medical images. However, TF specification should be supported by informative search spaces, interactive data exploration tools and...

Research has begun to explore the use of virtual humans (VHs) in clinical interviews (Bickmore, Gruber, & Picard, 2005). When designed as supportive and ‘‘safe’’ interaction partners, VHs may improve such screenings by increasing willingness to disclose information (Gratch, Wang, Gerten, & Fast, 2007). In health and mental health contexts, patients are often reluctant to respond honestly. In th...

Assembly of herpes simplex viruses (HSV) is a poorly understood process involving multiple redundant interactions between large number of tegument and envelope proteins. We have previously shown (G. E. Lee, G. A. Church, and D. W. Wilson, J. Virol. 77:2038-2045, 2003) that the virion host shutoff (Vhs) tegument protein is largely insoluble in HSV-infected cells and is also stably associated wit...

RT-PCR methods have been applied to the detection and sequencing of the glycoprotein gene of viral haemorrhagic septicaemia virus (VHSV), the rhabdovirus which causes viral haemorrhagic septicaemia (VHS) in farmed salmonid fish. Phylogenetic analysis of a 360 nt region of the glycoprotein gene from a range of marine and fresh water VHSV isolates identified three genogroups, I-III. Significantly...

The authors used flash electroretinography to demonstrate dysfunction of the photopic and scotopic retina in patients with dementia with Lewy bodies and visual hallucinations (VHs) compared with patients with Parkinson disease, patients without VHs, and controls. The retinal dysfunction may be related to slight alteration of the photoreceptors and numerous pale inclusions in the outer plexiform...

BACKGROUND We investigated whether a volitional helpsheet (VHS), a brief psychological intervention, could reduce repeat self-harm in the 6 months following a suicide attempt. METHODS We did a prospective, single-site, randomised controlled trial. Patients admitted to a hospital in Edinburgh, UK, after a suicide attempt were deemed eligible for the study if they were over the age of 16 years,...

We have determined the 2 A X-ray structure of the 219-residue N-terminal VHS and FYVE tandem domain unit of Drosophila Hrs. The unit assumes a pyramidal structure in which the much larger VHS domain (residues 1-153) forms a rectangular base and the FYVE domain occupies the apical end. The VHS domain is comprised of an unusual "superhelix" of eight alpha helices, and the FYVE domain is mainly bu...

The Tom1 (target of Myb 1) protein has VHS and GAT domains in N-terminal and central parts, respectively. The VHS domain has been found in a number of proteins, some of which have been implicated in intracellular trafficking and sorting. We previously showed that Tom1 forms a complex with Tollip, which has been reported to function in interleukin-1 (IL-1)-dependent signaling. In this study, we ...
