‎The largest class of hyperstructures is the one which satisfies the weak properties; these are called $H_{v}$-structures‎. ‎In this paper we introduce a special product of elements in $H_{v}$-group $H$ and define a new class of $H_{v}$-groups called strongly $H_{v}$-groups‎. ‎Then we show that in strongly $H_{v}$-groups $beta=beta^{ast}$‎. ‎Also we express $theta$-hyperoperation and investigat...

This paper describes two preliminary experiments concerned with the construction of a robot head. The initial design and research is aimed at producing a system with two cameras and two microphones on a system capable of operating with the same degrees of freedom and reflex times as its biological counterpart. Whilst the primary goal of the project is develop an anthropomorphic system with the ...

THEWORK OF DIVERSITY IN LIBRARIES BEGINS at the crossroad where superiority, inaction, and denial become intolerable. Yet in working toward true diversity, we work without the familiar construct of a mainstream. We respond to, or ignore, repetitive critique of being too exclusive or not inclusive enough. We decide whether it is appropriate to quantify the existence of a people or to trust what ...

I propose a comprehensive account of negation as a modal operator, vindicating a moderate logical pluralism. Negation is taken as a quantifier on worlds, restricted by an accessibility relation encoding the basic concept of compatibility. This latter captures the core meaning of the operator. While some candidate negations are then ruled out as violating plausible constraints on compatibility, ...

Let G and H be connected graphs. The tensor product G + H is a graph with vertex set V(G+H) = V (G) X V(H) and edge set E(G + H) ={(a , b)(x , y)| ax ∈ E(G) & by ∈ E(H)}. The graph H is called the strongly triangular if for every vertex u and v there exists a vertex w adjacent to both of them. In this article the tensor product of G + H under some distancebased topological indices are investiga...

Before discussing the pathogenesis and clinical aspects of this disease, clarification of some of the pertinent terminological definitions may be in order. Hypertrophic emphysema is the most commonly used designation of this disease. Also, it is known under the following names: genuine emphysema, idiopathic emphysema, diffuse vesicular emphysema, obstructive emphysema, dystrophlc emphysema, pul...

Our question answering system was built with a number of priorities in mind. First, we wanted to experiment with natural language processing (NLP) technologies such as shallow parsing, named entity tagging, and coreference chaining. We felt that the small number of terms in the questions coupled with the short length of the answers would make NLP technologies clearly beneficial, unlike previous...

2 Principal contact: This year our primary goal was to improve on the performance of our TREC-8 system. In addition to improving the system directly, we worked on a number of tools to aid our development. We continued our work on a tool for automatic scoring of system responses, a “judge” program. We designed a tool for doing regression testing of question answering systems. W...

Rats were immunized ( 1 ) with Jensen rat sarcoma tissue; ( 2 ) with emulsions of normal rat spleen; ( 3 ) with normal rat blood. Sera from rats of these three series were tested against ( a ) cultures of Jensen rat sarcoma cells; ( b ) cultures of normal spleen cells; (c) cultures of mouse carcinoma 63; ( d ) cultures of cells of normal mouse spleen. Jensen Rat Sarcoma Tissue as Antigen: Two s...

There is one concept in medicine which is prominent, the symptom. The omnipresence of the symptom seems, however, not to be reflected by an equally prominent curiosity aimed at investigating this concept as a phenomenon. In classic, traditional or conventional medical diagnostics and treatment, the lack of distinction with respect to the symptom represents a minor problem. Faced with enigmatic ...
