Downlo have recently developed a novel optical technology, partial wave spectroscopic (PWS) microscopy, is exquisitely sensitive to the nanoarchitectural manifestation of the genetic/epigenetic alterations of arcinogenesis. Our approach was to screen for lung cancer by assessing the cheek cells based on emergnetic/epigenetic data which suggests that the buccal epithelium is altered in lung fiel...

The Traveling Salesman Problem (TSP) is a famous NP-hard problem typically solved using various heuristics. One of popular heuristics class is k-opt local search. Though these heuristics are quite simple, combined with other techniques in an iterated local search (ILS) framework they show promising results. In this paper, we propose to combine the 2-opt, 3-opt and 4-opt local search algorithms ...

BACKGROUND Food texture plays an important role in food intake regulation. In previous studies we showed a clear effect of viscosity on ad libitum food intake and found indications that eating rate, bite size, and oral processing time (OPT) could play a role. OBJECTIVE The objective was to determine the effect of bite size and OPT of a food on satiation, defined as ad libitum food intake. D...

This paper proposes a new method of feature extraction called twodimensional optimal transform (2D-OPT) useful for appearance based object recognition. The 2D-OPT method provides a better discrimination power between classes by maximizing the distance between class centers. We first argue that the proposed 2D-OPT method works in the row direction of images and subsequently we propose an alterna...

We describe the implementation of an OPT plate to perform optical projection tomography (OPT) on a commercial wide-field inverted microscope, using our open-source hardware and software. The OPT plate includes a tilt adjustment for alignment and a stepper motor for sample rotation as required by standard projection tomography. Depending on magnification requirements, three methods of performing...
