Monophasic action potentials in a patient with multiform ventricular tachycardia without QT prolongation.

Emori, T, Ohe, T, Shimomura, K

A 41 year old woman had multiform ventricular tachycardia without QT prolongation. Monophasic action potentials were recorded from the right ventricle during the attacks of multiform ventricular...

Delayed improvement of autonomic nervous abnormality after the Maze procedure: time and frequency domain analysis of heart rate variability using 24 hour Holter monitoring

Fukushima, K., Emori, T., Shimizu, W., Kurita, T., Aihara, N., Kosakai, Y., ...

A Second Elementary Proposition Concerning the Formation of Customs Unions

Kemp, M.C., Shimomura, K.

The conclusions of the 1976 Kemp-Wan proposition are shown to be substantially valid even if all tariff vectors, both pre-uion and post-union, are optimally chosen.

Trade Gains in Chaotic Equilibrium.

Kemp, M.C., Shimomura, K.

In the present note we construct an overlapping-generations (OLG) example in which free trade is Pareto-improving and the world equilibrium chaotic. The example is simple, but it is not incompatible...
