BACKGROUND DNA-based testing has been gaining acceptance as a tool for authentication of a wide range of food products; however, its applicability for testing of herbal supplements remains contentious. METHODS We utilized Sanger and Next-Generation Sequencing (NGS) for taxonomic authentication of fifteen herbal supplements representing three different producers from five medicinal plants: Ech...

This paper addresses the problem of estimating the rendering time for a real-time simulation. We study different factors that contribute to the rendering time in order to develop a framework for rendering time estimation. Given a viewpoint (or view cell) and a list of potentially visible objects, we propose several algorithms that can give reasonable upper limits for the rendering time on consu...

The physiology of human visual perception helps explain different uses for color and luminance in visual arts. When visual fields are isoluminant, they look the same to our luminance processing pathway, while potentially looking quite different to the color processing path. This creates a perceptual tension exploited by skilled artists. In this paper, we show how reproducing a target color usin...

3D rendering is a kind of application which is not only computation intensive but also data intensive. 3D rendering can be easily parallelized by rendering different frames at the same time and the rendering work of each frame is independent from others. Parallel 3D rendering is typically I/O bound: many rendering programs spend lots of their execution time reading data from data server rather ...

This paper explores two general methods for incorporating volumetric uncertainty information in direct volume rendering. The goal is to produce volume rendered images that depict regions of high (or low) uncertainty in the data. The first method involves incorporating the uncertainty information directly into the volume rendering equation. The second method involves post-processing information ...

Concurrent team strategy is widely employed by firms in large projects. This research investigates the design of incentives and the role of collaboration for concurrent teams. Proposing and studying two types of reward policies: individual-based reward (IBR) and group-based reward (GBR), we characterize the structure of incentives, and demonstrate that firms can achieve maximal profits with col...

NON-PHOTOREALISTIC RENDERING OF ALGORITHMICALLY GENERATED TREES

This paper presents hybrid rendering that combines the use of photorealistic and non-photorealistic rendering styles in the same image. This allows to extend the set of expression dimensions available in a visualization environment. To provide general applicability, this use of hybrid rendering styles is controlled by an XML-based scene description. We discuss the according schema definition an...

Previously, we showed that ZFN-mediated induction of double-strand breaks (DSBs) at the intended recombination site enhanced the frequency of gene targeting (GT) at an artificial target locus using Agrobacterium-mediated floral dip transformation. Here, we designed zinc finger nucleases (ZFNs) for induction of DSBs in the natural protoporphyrinogen oxidase (PPO) gene, which can be conveniently ...

We conducted point counts in the alpine zone of the Presidential Range of the White Mountains, New Hampshire, USA, to estimate the distribution and density of the rare endemic White Mountain Fritillary (Boloria chariclea montinus). Incidence of occurrence and density of the endemic White Mountain Fritillary during surveys in 2012 and 2013 were greatest in the herbaceous-snowbank plant community...
