Building robotic sensor networks (RSNs) for air quality monitoring application is a challenging frontier for robotic research. Such systems must operate for extended periods of time in unstructured and complex domains. The implementation requires addressing numerous issues at the systems level such as energy efficiency, planning, and controlling robots’ trajectories for achieving robust operati...

Contrary to older views, with modern treatment some or many patients with schizophrenia may show intervals of recovery. The current 15-year prospectively designed follow-up research comparing schizophrenia patients with other types of psychotic and nonpsychotic patients studied how many schizophrenia patients ever show intervals of recovery. Two hundred seventy-four early young psychiatric pati...

We report the development of a low-cost chronic multi-channel microwire electrode array for recording multi-unit cortical responses in behaving rodents. The design was motivated by three issues. First, standard connector systems tended to disconnect from the head-stage during extended periods of behavior. Disconnections resulted in a loss of data and an interruption of the animals' behavior. Se...

hepatitis c virus (hcv) infection is highly prevalent in thalassemic patients, and this may decrease the serum antibody response to hepatitis b virus (hbv) vaccine. there is also some alteration of the immune system in multi-transfused thalassemic patients, as a consequence of iron overload. we investigated whether hcy infection may reduce the effectiveness of hby vaccine in multi - transfused ...

[1] It has been proposed that solar cycle irradiance variations may affect the whole planet’s climate via the stratosphere, the Quasi-Biennial Oscillation (QBO) and Arctic Oscillation (AO). We test this hypothesis by examining causal links between time series of sunspot number and indices of QBO, AO and ENSO activity. We use various methods: wavelet coherence, average mutual information, and me...

This paper reveals a study on air pollution process over North China, applying remote sensing technology, using satellite observation and in situ measurements during the twenty-first Asia-Pacific Economic Cooperation (APEC) meeting, which was held in Beijing between 6 and 12 November when the clear weather was called “APEC-Blue”. In the meantime, pollutants concentrations including PM2.5 and PM...

In recent years, there has been an increasing interest in parallel computing. In parallel computing, multiple computing resources are used simultaneously in solving a problem. There are multiple processors that will work concurrently and the program is divided into different tasks to be simultaneously solved. Recently, a considerable literature has grown up around the theme of metaheuristic alg...
