Abstract Background Cluster headache is a primary condition characterized by severe headache accompanied by trigeminal autonomic signs.By definition, it is not attributed to underlying etiologies; however, under certain clinical characteristics, secondary etiologies must be ruled out.Case presentation We present the case of a 48-year-old Hispanic m
Complex-valued system identification has the ability 9GB to provide the basis for system analysis.So as to demonstrate the potential and internal mechanism of the complex-valued system, this paper proposes a novel complex-valued hybrid evolutionary (CSE) algorithm to optimize the complex-valued expression model (CEM).Complex-valued gene expression
In this paper we try to develop an algorithm for visual obstacle avoidance of autonomous mobile robot.The Hair Care input of the algorithm is an image sequence grabbed by an embedded camera on the B21r robot in motion.Then, the optical flow information is extracted from the image sequence in order to be used in the navigation algorithm.The optical
Aims: The aim of this in-vitro study was to compare the retention force of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) clasps by mechanical cycling test simulating ten years of use.Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar, it is divided into 24 Co-Cr clasps, and 48 PEEK
