Stimulation of pig peripheral blood lymphocytes with concanavalin A (Con A) provoked a rapid increase (two- to threefold) in the rate of ouabain-inhibitable K+ uptake observable within 3-10 min of stimulation with mitogen. At least two phases can be distinguished in the activation of the Na+/K+ pump: the early phase (till 3 h) is characterized by an(More)
This article critiques an advertisement in a theatre playbill by a bio-technology company for its commercial test for the BRCA1 and BRCA2 genetic mutation, which may indicate a higher risk for breast and ovarian cancer. The advertisement targets a vulnerable audience attending a play about one woman's isolated and painful death from ovarian cancer. It(More)
This study was undertaken to investigate the effects of salicylic acid (SA) and methyl jasmonate (MeJA) on anthocyanin induction, biomass accumulation, and color value (CV) indices for both pigment content (PC) and pigment production (PP) in callus cultures of Rosa hybrida cv. Pusa Ajay. A concentration-dependent response was exhibited by cultures on SA and(More)
The visual image of a talker provides information complementary to the acoustic speech waveform, and enables improved recognition accuracy, especially in environments corrupted by high acoustic noise or multiple talkers. Because most of the phonolog-ically relevant visual information is from the mouth and lips, it is important to infer accurately and(More)
We have developed visual preprocessing algorithms for extracting phonologically relevant features from the grayscale video image of a speaker, to provide speaker-independent inputs for an automatic lipreading ("speechreading") system. Visual features such as mouth open/closed, tongue visible/not-visible, teeth visible/not-visible, and several shape(More)
We present new procedures for preprocessing video images for automatic lipreading applications. Preprocessing consists of rst detecting the region of interest (ROI) using the eyes, nostrils and mouth followed by estimating salient features within the ROI. Our algorithms for ROI detection employ a low-pass Gaussian lter followed by a gray level thresholding(More)
We have shown previously that there is a good correlation between the degree of microtubule disassembly by methylmercury (MeHg) and the extent of inhibition of DNA replication in Concanavalin A (Con A)-stimulated mouse splenic lymphocytes. The purpose of this study was to determine if these two events are causally related and to examine the effects of(More)
Automobiles MULTIMODAL CONVERSATIONAL SYSTEMS FOR C urrently available in-vehicle speech recognition systems are designed around a single-utterance-command paradigm [2], with as many as 200 commands 1 that must be learned or referenced in a manual—an unpractical option while driving. The combination of a flexible dialogue-based speech system with a visual(More)
