introduction: ophthalmic plaque radiotherapy using i-125 radioactive seeds in removable episcleral plaques is often used in management of ophthalmic tumors. radioactive seeds are fixed in a gold bowl-shaped plaque and the plaque is sutured to the scleral surface corresponding to the base of the intraocular tumor. this treatment allows for a localized radiation dose delivery to the tumor with a ...

Existing problems for 3D extended target tracking and contour reconstruction under clutter environment are thoroughly investigated in this article. Due to the sparsity of available point cloud data interference from clutter, shape completion method, such as Point Completion Network (PCN), cannot reconstruct directly. Moreover, traditional Gaussian process (GP) model suffered computing overhead ...

Abstract Eusocial insects can employ various behavioural and physiological disease defences to avoid, resist tolerate pathogen infections in their closely related packed colonies, termed social immunity. Recent studies have shown that several molecules serve insect immunity, including chemical odours, venoms, immune-related proteins, etc. However, whether how microRNAs (miRNAs), whose precursor...

When children learn a name for a novel artifact, they tend to extend the name to other artifacts that share the same shape--a phenomenon known as the shape bias. The present studies investigated an intentional account of this bias. In Study 1, 3-year-olds were shown two objects of the same shape, and were given an explanation for why the objects were the same shape even though they were intende...

Sun-Gu Sun Hyun Wook Park, MEMBER SPIE Korea Advanced Institute of Science and Technology Department of Electrical Engineering 373-1 Guseong-dong Yuseong-gu, Daejeon 305-701 Korea E-mail: [email protected] Abstract. We propose an automatic target recognition (ATR) algorithm for recognizing nonoccluded and partially occluded military vehicles in natural forward-looking infrared (FLIR) im...

The target recognition from Radar images was a crucial step in our research. This paper presents a process and an adopted approach for Automatic Target recognition using Inverse Synthetic Aperture Radar (ISAR) image. Indeed, the process adopted is composed of three steps. In the first step, we achieve the edge detection using of three techniques: Fisher, Kmeans and Expectation-Maximization (E-M...

When participants search for a shape (e.g., a circle) among a set of homogenous shapes (e.g., triangles) they are subject to distraction by color singletons that are more salient than the target. However, when participants search for a shape among heterogeneous shapes, the presence of a non-target color singleton does not slow responses to the target. Attempts have been made to explain these re...
