OF THE DISCLOSURE A method and device are provided for affinity gradient focusing for directing at least one analyte in a solution containing a pseudostationary phase and located in a conduit or microchannel. The method includes establishing a gradient in a retention factor of the pseudostationary phase for the at least one analyte. The analyte is caused to be moved within the conduit whereby t...

The advantage of this method involves controlling the flow of current through all the connections – especially those used to measure the voltage. The measurement current flows through one set of connections, usually those that are farthest apart. If these connections are resistive (i.e., the connections are poor) there will be significant voltage drop across them. However, this voltage drop doe...

A new 3-TFT voltage-programmed pixel circuit with an in-pixel current source is presented, which can be largely insensitive to the TFT threshold voltage shift. The fabricated pixel circuit provides OLED current ranging from 25nA to 2.9μA, an on/off ratio of 116 at typical QVGA display timing. Author

The dynamic response of a magnetized collisionless plasma to an externally driven, finite size, sudden switch-on current source across the magnetic field has been studied using a two dimensional hybrid code. It was found that the predominant plasma response was the excitation of whistler waves and the formation of current closure by induced currents in the plasma. The results show that the curr...

Very often electroless electrolytes contribute to wastewater treatment problems. These electrolytes are used in electroless plating processes, which contain a variety of chemicals to meet special surface treatment requirements. Metal salts produce the base material for metal deposition and hypophosphite is delivering the electrons for the metal reduction process – it is basically the internal e...

this work reports the results of the application of the second-order maccormack method for numerical solution of‎ the conservative form of two-dimensional non-hydrostatic and fully compressible navier-stokes equations governing an inviscid and adiabatic atmosphere‎. various aspects of the computational approach such as discretization of the governing equations for the interior and boundary poin...

This manuscript presents the designing and investigative aspects of a low power, wide frequency range, and delay cell based 3 and 5-stage ring oscillator for RF-Ultra-WideBand application. The wide range of frequency is achieved by using two variable voltage sources i.e. control voltage source (Vcntrl) and tail current source (Vtail). A tail current improvement is responsible to control the cha...
