Insulin-producing cells derived from human embryonic stem cells (hESCs) or induced pluripotent stem cells (iPSCs) have for long been a promising, but elusive treatment far from clinical translation into type 1 diabetes therapy. However, the field is now on the verge of moving such insulin-producing cells into clinical trials. Although stem cell therapies provide great opportunities, there are a...

This work describes a framework for dealing with attention and categorization using a robot platform consisting of an articulated stereo-head with four degrees of freedom (pan, tilt, left verge, and right verge). As a practical result of this development, the system can select a region of interest, perform shifts of attention involving saccadic movements, perform an efficient feature extraction...

On-line learning robotic systems have many desirable properties. This work contributes a reinforcement learning framework for learning a time-constrained closed-loop control policy. The task is to verge the two cameras of a stereo vision system to foveate on the same world feature, within a limited number of perception-action cycles. On-line learning is beneficial in at least the following ways...

This is a retrospective study evaluating the risk factors for clinical anastomotic leakage after anterior resection in 64 patients with rectal cancer operated from November 2001 till August 2003. The percentage of anastomosis leakage was higher in those patients with diabetic, low albumin level, neoadjuvant radiotherapy, higher staging, and poorly differentiated tumour. However, these differenc...

without any doubt, road safety (rs) needs a precise planning in road accident prevention. rs effects on different fields of the life. therefore, response to this need in order to promote the rs as well as to save more lives is the most asset in each country. in the recent years, statistics have been shown that the numbers of mortalities due to road crashes decreased. this shows the true motion ...
