Effects of Anoxia on Solute Loss from Beetroot Storage Tissue (1992)

ZHANG, Q., LAUCHLI, A, GREENWAY, H.

Beetroot storage tissue that had been aged in an aerated solution was particularly suited for studies of solute losses duringanoxia; retention of betacyanin being a good indicator of tonoplast...

ON NON-UNIFORM DISTRIBUTIONS OF TRANSPORT CURRENT IN MULTIFILAMENTARY SUPERCONDUCTING WIRES (1984)

Irie, F., Sumiyoshi, F., Zhang, Q., Yamafuji, K., Kawashima, T.

We studied the change of current distributions in multifilamentary superconducting wires induced by the changing external magnetic field. The change of distribution from non-uniform into uniform one...

ADSORPTION BEHAVIOR OF DODECYLAMINE AND ITS EFFECT ON THE WETTABILITY AND CORROSION OF CARBON STEEL

Z. Y. CHEN, X. P. GUO, Q. ZHANG

The adsorption behavior of dodecylamine and its effect on the wettability and corrosion of carbon steel in hydrochloric acid solution were studied. Polarization data suggest that inhibition of carbon...

Acid reflux event detection using the Bravo wireless versus the Slimline catheter pH systems: why are the numbers so different?

Pandolfino, J E, Zhang, Q, Schreiner, M A, Ghosh, S, Roth, M P, Kahrilas, P J

Objective: This study analysed the relative accuracy of the Bravo wireless and the Slimline catheter-Mark III Digitrapper pH systems in the detection of acid reflux events.

Singularly Perturbed Markov Chains: Convergence and Aggregation

Yin, G., Zhang, Q., Badowski, G.

Asymptotic properties of singularly perturbed Markov chains having measurable and/or continuous generators are developed in this work. The Markov chain under consideration has a finite-state space...

GIANT MAGNETO-IMPEDANCE EFFECT OF MAGNETRON SPUTTERED Ni80Fe20/Cu COMPOSITE WIRES

Q. ZHANG, Q. M. MAO, J. Z. RUAN, Q. J. WANG, X. L. YANG, Z. J. ZHAO, ...

Rapid Gate Matching with Don't Cares

Q. Zhang

Ending the logic synthesis, the technology mapping step maps the Boolean function on physical cells. This itep is based on a matching check, which complexity depends on the number of library cell...

Iterative Exponential Filtering for Large Discrete Ill-Posed Problems

D. Calvetti, L. Reichel, Q. Zhang

We describe a new iterative method for the solution of large, very ill-conditioned linear systems of equations that arise when discretizing linear ill-posed problems. The right-hand side vector...
