BACKGROUND Prevention and early detection of arterial stiffness are required to avoid severe cardiovascular events. Recently, new noninvasive arterial stiffness indices, the arterial pressure volume index (API) and the arterial velocity pulse index (AVI), have been developed. The purpose of this study was to examine the clinical validity of these new indices by investigating the association bet...

With technology of digital image recognition, the data frames include vehicle’s digital image can be detected automatically from an Audio Video Interleaved (AVI) File, and vehicle type will be recognized automatically. The system consists of four modules: Reading AVI file and decomposing it into digital image frames; Motion detection; Vehicle’s digital image processing; Module of vehicle type c...

Extending the characterization of the directional derivatives of a strongly regular solution to a variational inequality under parameter perturbations, this paper derives a first-order sensitivity result for a monotone-plus affine variational inequality (AVI) having non-isolated solutions. The result employs a “directional AVI” whose solutions provide the directional derivatives, if they exist,...

In the last decades, several automated visual inspection (AVI) systems have been developed and applied to a wide range of products, including wood (Pham and Alcock 2003). AVI is an automated form of quality control normally achieved using a camera connected to a computer. The AVI framework includes five processing stages: image acquisition, image enhancement, image segmentation, feature extract...

OBJECTIVE To analyze the relationship between dietary glycemic index (GI) and retinal microvasculature in adults. METHODS This was a cross-sectional study of 300 subjects from the EVIDENT II study. Dietary GI was calculated using a validated, semi-quantitative food frequency questionnaire. Retinal photographs were digitized, temporal vessels were measured in an area 0.5-1 disc diameter from t...

AVI provided an attractive opportunity for exploring novel visual interfaces for cultural heritage (CH). CH traditionally draws a lot of research attention when it comes to exploring the potential benefits from application of novel technology in realistic settings. At the same time, AVI focusses on exploring the state of the art visual interfaces and their application in various domains. The AV...

Three hybridomas which secrete antibodies to Mycobacterium avium were obtained by the fusion of p3u1 myeloma cells with spleen cells of mice immunized with M. avium culture sonicate. The reactivity of these monoclonal antibodies was determined in 16 species of mycobacteria by an enzyme-linked immunosorbent assay. An antibody, designated Avi-3, reacted only with M. avium and not with the referen...

The clinical significance of detecting early atherosclerosis is now widely recognized. Measurement methods available at present are usually not suitable for use in primary care where rapid screening for a large population is needed. The Arterial Velocity-pulse Index (AVI) and Arterial Pressure-volume Index (API) are new noninvasive arterial stiffness indices that can be rapidly measured using a...
