Adaptive Phasor Estimation Algorithm Based on a Least Squares Method
This paper proposes an adaptive phasor estimation algorithm based on a least square method that can suppress the adverse effect of an exponentially decreasing DC offset component in a phasor estimation process. The proposed algorithm is composed of three

Pumping charge with ac magnetic fluxes and the dynamical breakdown of Onsager symmetry [PDF]
We study the transport properties of setups with one and two mesoscopic rings threaded by ac magnetic fluxes of the form \Phi(t)=\Phi^{dc} + \Phi^{ac} cos(\Omega_0 t + \delta) and connected to two different particle reservoirs.

A Component-Reduced Zero-Voltage Switching Three-Level DC-DC Converter [PDF]
The basic Zero-Voltage Switching (ZVS) three-level DC-DC converter has one clamping capacitor to realize the ZVS of the switches, and two clamping diodes to clamp the voltage of the clamping capacitor. In order to reduce the reverse recovery loss of the diode as well as its cost, this paper proposes to remove one of the clamping diodes in basic ZVS ...

IRX-2, a Novel Immunotherapeutic, Enhances Functions of Human Dendritic Cells [PDF]
Background: In a recent phase II clinical trial for HNSCC patients, IRX-2, a cell-derived biologic, promoted T-cell infiltration into the tumor and prolonged overall survival. Mechanisms responsible for these IRX-2-mediated effects are unknown.

Step-up DC-DC converter passive component dimensioning in photovoltaic applications
Boost converter is a common solution for power conditioning of photovoltaic systems. Inductance and capacitance values of the boost converter are of high importance when the panel voltage ripple is examined. The ripple has a severe effect on the maximum power point tracking efficiency.
