Visual Question Answering (VQA) is the task of answering natural-language questions about images. We introduce the novel problem of determining the relevance of questions to images in VQA. Current VQA models do not reason about whether a question is even related to the given image (e.g. What is the capital of Argentina?) or if it requires information from(More)
This paper presents the Virginia Tech system that participated in the CoNLL-2016 shared task on shallow discourse parsing. We describe our end-to-end discourse parser that builds on the methods shown to be successful in previous work. The system consists of several components, such that each module performs a specific sub-task, and the components are(More)
A small bifunctional antigen (4-hydroxy-5-iodo-3-nitrophenyl)acetyl-epsilon-aminocaproyl-L-tyrosine-azobenzene-p-arsonate [NIP-cap-TYR(ABA)] was found to induce fair humoral antibody formation against NIP-cap but very little anti-ABA-TYR. This was observed in rats and guinea pigs. Prior immunization with ABA-TYR, either as such or coupled to dodecanoylated(More)
1 The dartos is a thin sheet of smooth muscle closely associated with the skin of the scrotum. Although known to play an important role in scrotal thermoregulation, there has been no detailed study into the pharmacology, or thermosensitivity, of the dartos from any species. Here, we investigate these two parameters in the isolated dartos muscle from rat. 2(More)
The muscarinic agonist carbachol antagonized positive inotropic responses of rabbit left atria to the beta-adrenoceptor agonist isoproterenol, the adenylate cyclase activator forskolin and the phosphodiesterase inhibitor IBMX. Carbachol also reduced cAMP levels elevated by isoproterenol, but had no significant effect on cAMP levels in the presence of either(More)
An irreversible inhibitor of histidine decarboxylase, alpha-fluoromethylhistidine (FMH), was used to inhibit histamine formation by mast cells in vivo. Even at doses of FMH sufficient to reduce histamine formation more than 95%, the ability of mast cells to synthesize histamine recovered rapidly. It was possible, however, to sustain levels of(More)
