TESTING AGGREGATION CONSISTENCY ACROSS GEOGRAPHY AND COMMODITIES
Consistent aggregation of production data across commodities and states was tested using Lewbel's generalized composite commodity theorem (GCCT). This was the first empirical GCCT test for consistent geographic aggregation and was applied to two groups ...

Comparison theorems for differential games. I
Journal of Differential Equations, 1972 The basic existence theory, of value and a saddle point, for (a) is given in [4] (see also [5]), and for (b) is given in [2, 31 (see also [S]). Our approach is to construct a family of games GA of fixed duration, with value VA, such that (i) the results of [6] can be applied to GA , and (ii) VA converges to the value V of the differential game under ...

An integral comparison theorem for cavitation diagrams
, 2020 In this paper we prove a comparison theorem for a functional whose positiveness is a necessary condition for the solvability of the problem of designing a hydrofoil by a given cavitation diagram. Original Russian Text © N.I. Manina and A.Ya.

Existence of entire solutions for non-local delayed lattice differential equations
Electronic Journal of Differential Equations, 2013 In this article we study entire solutions for a non-local delayed lattice differential equation with monostable nonlinearity. First, based on a concavity assumption of the birth function, we establish a comparison theorem.

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Applications in Plant Sciences, EarlyView.Abstract Premise Applied ecology can significantly influence policy decisions on environmental issues. Therefore, research in this field should be as transparent and reproducible as possible. Existing expertise from a broad range of disciplines should also be integrated into ecological research to allow researchers to maximize understanding of complex ...

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire
Advanced Physics Research, EarlyView.According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.
