Rodents have been widely used in the production of cerebral ischemia models. However, successful therapies have been proven on experimental rodent stroke model, and they have often failed to be effective when tested clinically. Therefore, nonhuman primates were recommended as the ideal alternatives, owing to their similarities with the human cerebrovascular system, brain metabolism, grey to whi...

In space art design, the recognition of expression is great help to understanding art. It very difficult obtain occlusion data from robot environment. particular, it challenging recognize occluded expression. case facial occlusion, extract features expressions by traditional methods. order reduce dependence on individuals, this paper proposes a cycle-consistent adversarial network and K-SVD dic...

BACKGROUND The present study aimed to determine and compare the anteroposterior position of the condyle in the mandibular fossa between groups of asymptomatic subjects with normal occlusion and asymptomatic subjects with Class I, Class II Division 1, and Class III malocclusions. MATERIAL AND METHODS Thirty persons with normal occlusion, 30 with Class I malocclusion, 30 with Class II Division ...

background: the aim of this study was to investigate the protective effects of crocin against tissue damages and leukocyte infiltration induced by renal ischemia/reperfusion. methods: in this experimental study, 35 male wister rats weighing 250-300 g were randomly divided into 5 groups; 1. operated controls, but no vessel occlusion was considered and passed during equivalent reperfusion period ...

This thesis is split into two parts: one part dealing with the management of occlusion in 3D environments, the other with the visualization of causal relations. Both of these parts fall within the general framework of visualization—the graphical representation of data (abstract or concrete) with the purpose of amplifying cognition—but they do so in different ways. 3D occlusion management, on th...

We introduced the concept of C-space entropy recently in [9] as a measure of knowledge of Cspace for sensor-based exploration and path planning for general robot-sensor systems. The robot plans the next sensing action to maximally reduce the expected C-space entropy, also called the Maximal expected Entropy Reduction, or MER criterion. The resulting view planning algorithms showed significant i...

Correctly interpreting a natural image requires dealing properly with the effects of occlusion, and hence, contour grouping across occlusions is a major component of many natural visual tasks. To better understand the mechanisms of contour grouping across occlusions, we (a) measured the pair-wise statistics of edge elements from contours in natural images, as a function of edge element geometry...

Current hypotheses for primate origins propose that nails and primate-like grasping hands and feet were important early adaptations for feeding in fine branches. Comparative research in this area has focused on instances of convergence in extant animals, showing that species with primate-like morphology feed predominantly from terminal branches. Little has been done to test whether animals with...

In this paper, an efficient pose-invariant face recognition method is proposed. This method is multimodal means that it uses 2D (color) and 3D (depth) information of a face for recognition. In the first step, the geodesic distances of all face points from a reference point are computed. Then, the face points are mapped from the 3D space to a new 2D space. The proposed mapping is robust under th...
