Thispaperpresentsaninitialimplementationand evaluation of a system that synthesizes visual speech directly from the acoustic waveform. An artificial neural network (ANN) was trained to map the cepstral coefficients of an individual's natural speech to the control parameters of an animated synthetic talking head. We trained on(More)
OBJECTIVE endoscopic mucosal resection with ligation (EMRL) is considered an efficient, safe method for the treatment of some esophageal, gastric and colorectal tumors. We conducted this study using a porcine model in order to compare the safety of esophageal EMRL with two multiband ligation systems, since many centers only use these ligator models in EMRL(More)
The present study used the endpoint of hypothermia to investigate cannabinoid and nociceptin/orphanin FQ (N/OFQ) interactions in conscious animals. Prior work has established that cannabinoids produce hypothermia by activating central cannabinoid CB(1) receptors. The administration of N/OFQ into the brain also causes significant hypothermia. Those data(More)
With the growing commercialization of watermarking techniques in various application scenarios it has become increasingly important to quantify the performance of watermarking products. The quantification of relative merits of various products is not only essential in enabling further adoption of the technology by society as a whole, but will also drive the(More)
A common clinical problem is the differentiation among ejection and regurgitant murmurs. Inhalation of amyl nitrite is useful for this purpose because it increases the intensity of ejection murmurs while decreases that of regurgitant ones. Because amyl nitrite is not easily available, inhaled isoproterenol was tested in seventeen patients with ejection(More)
Left ventricular systolic stress was studied in nineteen patients with mitral stenosis, twelve in sinus rhythm and seven in atrial fibrillation. Left ventricular dimensions and volumes and septal and posterior wall thickness were measured by means of M and two bidimensional echocardiography at rest and during isometric exercise. Expulsive indices:(More)
