background: to date, several imaging techniques to track stem cells are used such as positron emission tomography (pet), single photon emission computed tomography (spect), bioluminescence imaging (bli), fluorescence imaging, ct scan and magnetic resonance imaging (mri). although, overall sensitivity of mri compared to spect and bioluminescence techniques are lower, but due to high spatial reso...

the aim of this research was to determine the effect of contextual interference derived from self-regulation practice with regard to type of task on acquisition and retention of tracking tasks with an emphasis on meta-cognition hypotheses (cognition and meta-cognition phenomena). for this purpose, 24 right handed male and female students of yazd university (mean age: 22± 1.7) were selected via ...

While quantitative biology has gradually become the major trend of biology, researchers have put their eyes on analysis tools that can give them more quantitative read-out of the biological system. Cell biologists are researchers that have started to use quantitative image analysis tools at the earliest time, and by using these tools, information such as the dynamics of certain molecules of int...

Tracking of immune cells in vivo is a crucial tool for development and optimization of cell-based therapy. Techniques for tracking immune cells have been applied widely for understanding the intrinsic behavior of immune cells and include non-radiation-based techniques such as optical imaging and magnetic resonance imaging (MRI), radiation-based techniques such as computerized tomography (CT), a...

in this paper, we propose a novel method for fully automatic detection and tracking of human heads and faces in video sequences. the proposed algorithm consists of two modules: a face detection module and a face tracking module. the detection module, detects the face region and approximates it with an ellipse at the first frame using a modified version of adaboost cascaded classifier. the detec...

Bio-integrated lasers, that are lasers made of biological and biocompatible materials implanted into cells tissues, gaining interest from the research community. Here we show how whispering gallery mode microlasers microcavities solid beads or droplets can be used for sensing different processes in including inside cells. By making a predefined size they also to encode some information cell tra...

The minimization of the wireless cost of tracking mobile users is a crucial issue in wireless networks. Some of the previous strategies addressing this issue leave an open gap, by requiring the use of information that is not generally available to the user (for example, the distance traveled by the user). For this reason, both the implementation of some of these strategies and the performance c...
