A modified version of the point coordination function (PCF) in the IEEE 802.11 standard called Modified PCF has been introduced as an approach to improve channel utilization over the standard. It has been shown in our previous work that the utilization of the wireless channel can be significantly improved. In this paper, we investigate the performance of the Modified PCF when it is applied with a

With few exceptions the endoplasmic reticulum (ER) is considered a continuous system of endomembranes within which proteins and ions can move. We have studied dynamic structural changes of the ER in hippocampal neurons in primary culture and organotypic slices. Fluorescence recovery after photobleaching (FRAP) was used to quantify and model ER structural dynamics. Ultrastructure was assessed by el
This report is a result of the work in projects for The Swedish Rescue Services Agency and for The National Board of Civil Emergency Preparedness.
