In this study, we report the antibacterial activities of six polyphenols (i.e., luteolin, quercetin, scutellarin, apigenin, chlorogenic acid, and resveratrol) against 29 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), and in vitro antibacterial activities of two-drug combinations. All of the MRSA strains evaluated were clinical isolates from patients with MRSA bacteremi...

Molecular diagnostic methods using genetic material probes have been employed in the health care field for the detection and quantitation of several species of microorganisms (2, 5). These methods are faster and more suitable than traditional culture methods. In addition, the possibility of the inclusion of difficult-to-culture, uncultivable, or uncharacterized species in the set of target spec...

This paper presents a fl exible method for zoom lens calibration and modeling using a planar checkerboard. The method includes the following four steps. First, the principal point of the zoom-lens camera is determined by a focus-of-expansion approach. Second, the infl uences of focus changes on the principal distance are modeled by a scale parameter. Third, checkerboard images taken at varying ...

We prove that alternating links with two totally geodesic checkerboard surfaces are three projection the 1-skeleton of octahedron, cuboctahedron and icosidodecahedron. also characterize these as right-angled completely realisable show all hyperbolic weaving knots exceptions have both not geodesic.

We describe a technique to detect and localize features on checkerboard calibration charts with high accuracy. Our approach is based on a model representing the sought features by a multiplicative combination of two edge functions, which, to allow for perspective distortions, can be arbitrarily oriented. First, candidate regions are identified by an eigenvalue analysis of the structure tensor. ...

The ecological environment offered by virtual reality is primarily supported by visual information. The different image contents and their rhythmic presentation imply specific bottom-up and top-down processing. Because these processes already occur during passive observation we studied the brain responses evoked by the presentation of specific 3D virtual tunnels with respect to 2D checkerboard....
