For a wireless sensor network (WSN) to operate successfully in an application of detecting a mobile intruder, the sensor's sensing of the intruder and the communication between the tasking sensor(s) and the base station should be jointly considered for effective intrusion detection. Most related work either treats the two tasks separately or considers both(More)
Network connectivity, as a fundamental issue in a wireless sensor network(WSN), has been receiving considerable attention during the past decade. Most works focused on how to maintain full connectivity while conserving network resources. However, full connectivity is actually a sufficient but not necessary condition for many WSNs to communicate and function(More)
Network connectivity is a critical property that provides communication foundation for most wireless sensor network (WSN) applications to operate successfully. Existing results on the WSN connectivity analysis are primarily based on a uniform distribution of sensors in a bounded field of interest. However, the sensor distribution can be non-uniform in(More)
Mitochondria isolated from mesophyll protoplasts differed from mitochondria isolated directly from leaves of Avena sativa in that protoplast mitochondria (a) had a lower overall respiratory capacity, (b) were less able to use low concentrations of exogenous NADH, (c) did not respond rapidly or strongly to added NAD, (d) appeared to accumulate more(More)
The effect of histamine on Mg-ATPase was assessed in homogenates of gastric biopsies taken from the body and antrum of the stomach of patients with and without duodenal ulcer (DU). Histamine at concentrations greater than 10(-7) mol/l caused significant activation of this crude enzyme activity in the body mucosa from both groups of patients; maximum(More)
