  • Verbal and compositional lexical aspect provide the underlying temporal structure of events. Knowledge of lexical aspect, e.g., (a)telicity, is therefore required for interpreting event sequences in discourse (Dowty, 1986; Moens and Steedman, 1988; Passoneau, 1988), interfacing to temporal databases (Androutsopoulos, 1996), processing temporal modifiers (Antonisse, 1994), describing allowable alternations and their semantic effects (Resnik, 1996; Tenny, 1994), and selecting tense and lexical items for natural language generation ((Dorr and Olsen, 1996; Klavans and Chodorow, 1992), cf.

  • For 250 years, veterinary medicine and its scientific underpinning, veterinary science, have struggled to gain the confidence and respect of clients, fellow health scientists and practitioners, and the general public. And it has been accomplished by means of the scientific method and strict objectivity. To embrace unproven or even discredited “complementary and alternative” techniques surely is regressive both for patients and for veterinarians.

  • An analysis of English tense and aspect is presented that specifies temporal precedence relations within a sentence. The relevant reference points for interpretation are taken to be the initial and terminal points of events in the world, as well as two "hypothetical" times: the perfect time (when a sentence contains perfect aspect) and the progressive or during time. A method for providing temporal interpretation for nontensed elements in the sentence is also described.

  • This minireview covers the research carried out in recent years into differ-ent aspects of the function of the flavoproteins involved in cyanobacterial photosynthetic electron transfer from photosystem I to NADP + , flavodox-in and ferredoxin–NADP + reductase. Interactions that stabilize protein– flavin complexes and tailor the midpoint potentials in these proteins, as well as many details of the binding and electron transfer to protein and ligand partners, have been revealed.

  • Although the mechanism of RNA cleavage by RNases has been studied for many years, there remain aspects that have not yet been fully clarified. We have solved the crystal structures of RNase Sa2 in the apo form and in complexes with mononucleotides. These structures provide more details about the mechanism of RNA cleavage by RNase Sa2.

  • This paper proposes a s y s t e m of mapping classes of syntactic structures as instruments for automatic text understanding. The s y s t e m illustrated in Japanese consists of a set of verb classes and i nfo r m a t i o n on mapping them together with noun phrases, tense and aspect. The system. having information on direction of possible inferences between the verb classes with i n f o r m a t i o n on tense and aspect, is s u p p o s e d to be...

  • In this paper we discuss some problems arising in German-Russian Machine Translation with regard to tense and aspect. Since the formal category of aspect is missing in German the information required for generating Russian aspect forms has to be extracted from different representation levels. A sentence based procedure for aspect choice in the MT system VIRTEX is presented which takes lexieal, morphological and semantic criteria into account. The limits of this approach are shown. To overcome these difficulties a human interaction component is proposed. ...

  • English as their native tongue are compelled to write their work in English which, by chance, happens to be the de facto, universal language of science. As a result, it compelled me to address many of the aspects of scientific writing from the viewpoint of non-native English speaking authors and to emphasise that they are not as disadvantaged as they perhaps may think. The language of science which conveys logic and reasoning, is independent of the language in which it happens to be expressed.

  • Globally, the production quantities of agricultural commodities are increasingly fluctuating, and crop yields are low in relation to the needs of the world population. Furthermore, arthropod pests destroy 20-30% of the world’s food supply every year. They damage agricultural crops and harvested food, as well as transmit diseases to humans and animals. Stored-product insects infest raw grain, processed cereals, warehouses, and flour and feed mills. The presence of insects in commodities or structures leads to quantitative and qualitative losses of grain and processed food....

  • There are several reasons that may explain why the prevalence of heart failure is increasing: ageing of the population, the success in prolonging survival in coronary patients, and the success in postponing coronary events by effective prevention in those patients at high risk or those patients who have already survived a first event (secondary prevention) (Senni et al, 1999). Advances in medical therapy have resulted in improved survival in patients with moderate and severe heart failure, but the prognosis for end-stage heart failure patients still remains poor.

  • How people deal with risks is one of the most interesting aspects of the human condition. Perceptions of risk are complex, and people deal with risks in different, often irrational, ways. Young, healthy people consider themselves immortal and immune from long-term, degenerative diseases. As a consequence they engage in risky dietary and smoking behaviors that enhance the chances of such diseases in later life.
