This paper presents the particle swarm optimization based maximum power point tracking (MPPT) approach for maximizing output power of photovoltaic (PV) array under partially shaded conditions (PSC). During PSC, the P-V characteristic becomes more complex with multiple maximum power points (MPP). Most of the conventional MPPT approaches will be trapped at the local MPP and hence limiting the maximum...
In this report, we demonstrate a semi-integrated electrical biosensor for the detection of rare circulating tumor cells (CTCs) in blood. The sample was first enriched through a combination of immunomagnetic isolation and size filtration. The integration of both methods provided a high enrichment performance with a recovery rate above 70%, even for very low numbers of cancer cells present in the original...
