Users’ interactions with search engines is shifting towards more complex information needs and the need for a deeper semantic understanding of the query intent is needed. In this paper we propose a novel semantic matching criterion that adopts distributed representations of words in order to address complex information needs in a scalable way. We show that combining this criterion with other we...

The effects of different kinds of biotic and abiotic stress on crops can be lessened through exogenous application of different biostimulant products. Although some of these products come from enzymatic hydrolysates derived from animal remains, the literature does not contain references to the use of enzymatic hydrolysates obtained from animal hemoglobin, specifi cally porcine blood. With the a...

The specific defect in molecules of sickle hemoglobin (HbS) has been known for many years (1), but the nature of the assembled polymers of HbS which distort susceptible erythrocytes remains unclear. Several structural forms of sickled hemoglobin have been observed in electron microscopic studies, including a mat-like arrangement of fibers (2), empty hexagonal crystals (3), microtubules (4), and...

Considerations from a network theory of the immune system suggest that human immunodeficiency virus and allogeneic stimuli may act synergistically to cause AIDS. The immune responses to these stimuli include two components that are directed against each other. In some AIDS risk groups other antigens that mimic major histocompatibility complex antigens may substitute for allogeneic stimuli. Impl...
