Abstract: In this paper, an economically consistent framework which yields dual measures of technical change is developed. The major advantages of the proposed approach over previous ones are that (i) the restrictive assumption of perfect competition is relaxed, (II) it is no longer necessary to use time to index technology levels, (iii) a parametric specification of the production or cost function is not needed, and (iv) no assumptions on the character of technical progress are required. The conventional assumption of constant returns to scale is, however, retained. Applications of the proposed methodology using Solow’s and Chinese state industry data yield results that broadly conform with expectations. (C) 1995 Academic Press, Inc.

Abstract: To measure the economic effects of political movements in China a simple econometric model is constructed. Investment is determined by a central planner maximizing a multiperiod objective function. Political events are modeled by exogenous changes in the shocks to productivity and to investment which affect the time paths of major economic variables. Effects of the events are measured by comparing the time paths generated by the model with and without the changes in the shocks. Without the Great Leap output and consumption per capita would have been 2.0 times as great in 1993, without the Cultural Revolution, 1.2 times as great. (C) 1996 Academic Press, Inc.

Abstract: The traditional second-order Fokker-Planck equation may not adequately describe the movement of solute in an aquifer because of large deviation from the dynamics of Brownian motion. Densities of alpha-stable type have been used to describe the probability distribution of these motions. The resulting governing equation of these motions is similar to the traditional Fokker-Planck equation except that the order alpha of the highest derivative is fractional.
In this paper, a space fractional Fokker-Planck equation (SFFPE) with instantaneous source is considered. A numerical scheme for solving SFFPE is presented. Using the Riemann-Liouville and Grunwald-Letnikov definitions of fractional derivatives, the SFFPE is transformed into a system of ordinary differential equations (ODE). Then the ODE system is solved by a method of lines. Numerical results for SFFPE with a constant diffusion coefficient are evaluated for comparison with the known analytical solution. The numerical approximation of SFFPE with a time-dependent diffusion coefficient is also used to simulate Levy motion with alpha-stable densities. We will show that the numerical method of SFFPE is able to more accurately model these heavy-tailed motions. (C) 2003 Elsevier B.V. All rights reserved.

Abstract: PURPOSE: The purpose of this study is to assess the role of 3D imaging using spiral CT for the detection and evaluation of early gastric carcinoma (EGC).
METHOD: Thirty-one patients with EGC underwent 3D and axial imaging using spiral CT, and all cases were confirmed at surgery. According to the pathologic specimens, one patient (3.2%) had type, I., five (16.1%) had type IIb, 13 (42.0%) had type IIc, three (9.6%) had types IIc+IIb, three (9.6%) had types IIc+III, two (6.5%) had types IIa+IIc, two (6.5%) had types IIb+IIc, and two (6.5%) had types IIb+III. Spiral CT was first performed with 3 mm collimation, 4.5 mm/s table feed, and a 1 mm reconstruction interval in the supine position after intravenous injection of Buscopan and ingestion of gas. The 3D shaded surface display renderings were performed, analyzed, and graded as excellent, good, or poor. Axial CT scanning was performed with 5 mm collimation, 7 mm/s table feed, and a 5 mm reconstruction interval in the prone position after ingestion of water.
RESULTS: With use of axial CT images, 20 of 31 tumors (64.5%) were detected. Tumors were suspected in two cases, but nine were not detected. With use of 3D images, 29 of 31 tumors (93.5%) were detected (p < 0.05). of the 31 cases of EGG, excellent 3D images were obtained in 6 patients (19.3%), good 3D images in 21 (67.7%), and poor 3D images in 2 (6.5%). In the two cases with poor images, the tumor was confined to the mucosal layer and the types were EGC IIc+IIb. In the remaining two cases (6.5%), the tumors were not detected by 3D images. In one case, the tumor was confined to the mucosal layer, and in the other it was located in the pyloric antrum. Both tumors were EGC type IIc. The two cases not detected by 3D imaging were also not detected by axial CT scanning. Conclusion: The detection rate of EGC is higher using 3D imaging than axial CT scan alone.
