The impact of high-voltage-high-frequency (HVHF) amplifiers on echo-signal quality is greater with very-high-frequency (VHF, ≥100 MHz) ultrasound transducers than with low-frequency (LF, ≤15 MHz) ultrasound transducers. Hence, the bias voltage of an HVHF amplifier must be stabilized to ensure stable echo-signal amplitudes. We propose a bias-voltage stabilizer circuit to maintain stable DC volta...

We propose a unitary procedure to reconstruct quantum secret for a quantum secret sharing scheme constructed from stabilizer quantum errorcorrecting codes. Erasure correcting procedures for stabilizer codes need to add missing shares for reconstruction of quantum secret while unitary reconstruction procedures for certain class of quantum secret sharing are known to work without adding missing s...

In this paper, we discuss stabilization problem for a class of switched nonlinear systems whose subsystem with trigonal structure. A backstepping switching control design is given. Based on backsteppping approach, stabilizer and a switching law are designed for such systems. The stabilization of the resulting closed-loop systems is proved via common Lyapunov function method.

Construction X is known from the theory of classical error control codes. We present a variant of this construction that produces stabilizer quantum error control codes from arbitrary linear codes. Our construction does not require the classical linear code that is used as an ingredient to satisfy the dual containment condition. We prove lower bounds on the minimum distance of quantum codes obt...

Chitosan is a natural polymer that can be used as source of materials because it has good characteristics. in the cosmetic sector humectant, thickener, moisturizer, antioxidant, sunscreen cream, and stabilizer. The shell chitosan shells an emulsion stabilizer Hand Body Cream product problems its unstable nature so oil water are easily separated. parameters observed were stability, pH, TPC. resu...

I show how to protect adiabatic quantum computation (AQC) against decoherence and certain control errors, using a hybrid methodology involving dynamical decoupling, subsystem and stabilizer codes, and energy gaps. Corresponding error bounds are derived. As an example, I show how to perform decoherence-protected AQC against local noise using at most two-body interactions.
