Abstract: Molecularly imprinted polymers (MIPs) are materials exhibiting molecular recognition of a target molecule. MIPs are synthesized in the presence of an aflatoxin template, a mimic to the targeted molecule, used as an imprint that is further washed away with suitable solvent after completion of the polymerization process, leaving a cavity in the polymer of the same stereochemistry, functionality and morphology to the template. When the MIP encounters an aflatoxin, the molecule is bound in the cavity with a receptor-like affinity.

Abstract: A memristor linear modeling method for switched reluctance motors. A switched reluctance motor linear phase inductance characteristic element is constructed using non-inverting operational amplifier circuit and inverting operational amplifier circuit.  The angular speed of the switched reluctance motor is integrated, via scaling and integration circuits to acquire rotor position angle, .theta.. The rotor position angle is the input of the linear phase inductance characteristic element (L), which outputs phase inductance, L(.theta.). A current reversing circuit is connected between an input and an output of a multiplier. Input voltage, V(t), is connected to the same multiplier input.  Phase inductance L(.theta.) is another input of the multiplier. The relation is such that input current i(t) =[.alpha.~(.theta.)]~ V(t), where .alpha. is constant coefficient. The method allows memristor resistance to change as rotor position changes, serves as a basis for constructing complete switched reluctance motor circuit models, and facilitates real-time control.

Abstract: The method allows a pressure test of a string with external packers without having the packer setting apparatus exposed to tubing pressure so that at a later time and at a lower pressure than the pressure test pressure, the external packers can be set with annulus pressure opened to a piston that references a low pressure chamber. The packers can be set in any desired order. Thereafter, a circulation sub can be triggered to open to allow the tracking to start. Fracking each interval beyond the first in an uphole direction can be accomplished with pumping ever increasing balls to seats associated with sliding sleeves to open the sleeves in order. In cemented completions, after a pressure test, a ported sub can open on a timer or other signal to allow pumping a combination of a bridge plug and a perforating gun to the desired location.
