The interaction between P-450czl and NADPH-cytochrome P-450 reductase, both purified from bovine adrenocortical microsomes, has been investigated in a reconstituted system with a nonionic detergent, Emulgen 913, by kinetic analysis and gel filtrations. Steady state kinetic data in progesterone 2 1-hydroxylation showed formation of an equimolar complex between the two enzyme proteins at low Emul...

The significance of the recent finding of the velocity distribution function of the steady-state Boltzmann equation under a steady heat current obtained by Kim and Haykawa (J. Phys. Soc. Jpn. 72, 1904 (2003)) is discussed. Through the stability analysis, it seems that the steady solution is stable. One of possible applications to the nonequiliburium Knudsen effect in which one cell at equilibri...

-Three methods for numerical transient analysis of Markov chains, the modified Jensen's method (Jensen's method with steady-state detection of the underlying DTMC and computation of Poisson probabilities using the method of Fox and Glynn [1]), a third-order L-stable implicit Runge-Kutta method, and a second-order L-stable method, TR-BDF2, are compared. These methods are evaluated on the basis o...

Artificial microbial ecosystems have been increasingly used to understand principles of ecology. These systems offer unique capabilities to mimic a variety of ecological interactions that otherwise would be difficult to study experimentally in a reasonable period of time. However, the elucidation of the genetic bases for these interactions remains a daunting challenge. To address this issue, we...

In the present study, a data-driven ripple-free design is proposed for dual-rate sampled-data control system in which sampling interval of plant output longer than holding input. The objective study to improve steady-state intersample response without changing sampled and using model. To achieve directly from controlled data, an add-on input based on null space step responses existing used. ope...

steady state creep of the alloy was in a thermodynamical steady state, (2) which configuration of the dislocation network was contributing to the creep strength, and (3) which change in the dislocation network was the cause of the creep recovery. Specimens were furnace-cooled under stress and then observed by transmission electron microscopy. The creep stress was reduced during the test and the...

This paper is concerned with several eigenvalue problems in the linear stability analysis of steady state morphogen gradients for several models of Drosophila wing imaginal discs including one not previously considered. These problems share several common difficulties including the following: (a) The steady state solution which appears in the coefficients of the relevant differential equations ...

This paper considers the well known Romer model of endogenous technological change and its extension where different intermediate capital goods are complementary, introduced in (Benhabib, Perli, and Xie 1994). They have shown that this modiÞcation allows indeterminate steady state for relatively mild degrees of the complementarity. The authors were able to derive analytically sufficient conditi...

We have investigated the oscillatory behavior of cardiac cellular elements simulated by two electrophysiological models: the van Capelle and Durrer (VCD) model and the sinoatrial node cell model of Yanagihara, Noma, and Irisawa (YNI). The VCD model behavior was examined systematically by using continuation-bifurcation analysis. Bifurcation diagrams were constructed as a function of Qit1, an int...

We consider a Diamond-type model of endogenous growth in which there are three assets: fiat money, government bonds, and equity. Because of productivity shocks, the equity return is uncertain, and risk-averse investors require a positive equity premium. Typically, there exist two steady states, but only one of them turns out to be stable. Tight monetary policy is harmful for growth in the stabl...
