Background: Colorectal Cancer (CRC) is the third common cancer in the world. One of the pathways in colorectal tumor genesis is Microsatellite Instability (MSI+). MSI is detected in about 15% of all colorectal cancers. Colorectal tumors with MSI have dis-tinctive features compared with Microsatellite Stable (MSS) tumors. Due to the high percentage of MSI+ in patients with CRC in Iran, screening...
We present a new multimodal system that combines stereoscopic and audio-based source localization to track the position of a flying bat. Also presented are novel algorithms for audio source localization. The bat was allowed to fly in an anechoic room and monitored by two high-speed video cameras. The vocalizations of the bat were simultaneously recorded from six microphones. The data was then p...
The main aim of the present study is to achieve optimum design of reinforced concrete (RC) plane moment frames using bat algorithm (BA) which is a newly developed meta-heuristic optimization algorithm based on the echolocation behaviour of bats. The objective function is the total cost of the frame and the design constraints are checked during the optimization process based on ACI 318-08 code. ...
In robot-assisted manufacturing or assembly, following a predefined path became critical aspect. general, inverse kinematics offers the solution to control movement of manipulator while trajectory. The main problem with approach is that are computationally complex. For redundant manipulator, this complexity further increased. Instead employing kinematics, can be reduced by using heuristic algor...
Aiming at the phenomenon of slow convergence rate and low accuracy of bat algorithm, a novel bat algorithm based on differential operator and Lévy flights trajectory is proposed. In this paper, a differential operator is introduced to accelerate the convergence speed of proposed algorithm, which is similar to mutation strategy "DE/best/2" in differential algorithm. Lévy flights trajectory can e...
While effective methods for bit-level verification of low-level properties exist, system-level properties that entail reasoning about a significant part of the design pose a major verification challenge. We present the Bit-level Analysis Tool (BAT), a state-of-the-art decision procedure for bit-level reasoning that implements a novel collection of techniques targeted towards enabling the verifi...
Link quality monitoring in wireless sensor network has been studied in detail. There are many measurements for link quality in WSN presented by researchers. Relative to the comprehensive study for link quality monitoring, there are very little research for link quality aggregation and representation for link situation of the whole network. This paper presents a three levels framework for global...
This paper describes the design of the ‘BAT’ (Bonn Articulated Tracker) visual tracking framework. This system allows the easy implementation of real-time, multi-camera motion tracking that can be distributed (also in multithreaded sense) across several computing nodes (or CPU cores). The system in itself does not realize any specific tracking system, but manages a meta-algorithm flow between p...
Nature-inspired metaheuristic algorithms have attracted much attention in the last decade, and new algorithms have emerged almost every year with a vast, ever-expanding literature. In this chapter, we briefly review two latest metaheuristics: bat algorithm and cuckoo search for global optimization. Bat algorithm was proposed by Xin-She Yang in 2010, inspired by the echolocation of microbats, wh...
conclusions recent treatment, in addition to age, gender and daylight duration were proved as strong independent determinants on bat development and the level of metabolic activity at [18 f] dg pet/ct and should be considered as an important confounding factor in future researches. results one-hundred eighteen studies were recognized to demonstrate foci of fdg bat uptake (3.1%, mean age: 22.7 y...
