conclusions as it was previously reported by the world health organization (who) on hav infection in the country, this study revealed a high prevalence of hav infection in mashhad. background hepatitis a virus (hav) is the most common cause of acute viral hepatitis worldwide, mostly in developing countries. objectives this population-based survey was performed to investigate hav seroprevalence ...

because of the piecewise linear nature of the data envelopment analysis (dea) frontier, the optimal multipliers of the dea models may not be unique. choosing weights from alternative optimal solutions of dual multiplier models is one of the most frequently studied subjects in the context of dea. in this paper, the authors have been inspired by the idea of cooper et al. (2011) to propose a linea...

penicillin g acylase from e. coli ta1 was immobilized by cross-linked enzyme aggregates (clea), a new method for immobilization. this biocatalyst and commercial immobilized penicillin g acylase (pga-450) were used to study the effect of ph, temperature and substrate concentration on the synthesis of ampicillin from phenyl glycine methyl ester (pgme) and 6-aminopenicillanic acid (6-apa). compare...

The implementation of high-fidelity swapping operations is vital importance for executing quantum algorithms on a processor with limited connectivity. We present an efficient pulse-control technique, the cross-cross resonance (CCR) gate, to implement iswap and swap gates dispersively coupled fixed-frequency transmon qubits. key operation CCR gate simultaneous driving both qubits at frequency an...
