A generalized Krein-Rutman theorem for a strongly positive bounded linear operator whose spectral radius is larger than essential established: the of an algebraically simple eigenvalue with eigenvector and other eigenvalues are less radius.
The concepts of selectable and unselectable sets are proposed to describe some interesting dynamical properties a class recurrent neural networks (RNNs) with saturated piecewise linear transfer function. A set neurons is said be if it can co-unsaturated at stable equilibrium point by external input. not selectable, i.e., such never any regardless what the input is. importance that they enable new perspective memory in RNNs. Necessary sufficient conditions for existence obtained. As an...

Wheat straw, a typical agricultural solid waste, was employed to clarify the effects of torrefaction on structural features and combustion reactivity biomass. Two temperatures (543 K 573 K), four atmospheres (argon, 6 vol.% O2, dry flue gas raw gas) were selected. The elemental distribution, compositional variation, surface physicochemical structure each sample identified using analysis, XPS, N2 adsorption, TGA FOW methods. Oxidative tended optimize fuel quality biomass effectively,...
It is well known that, in the study of dynamical properties nonlinear evolution system with nonlocal dispersals, principal eigenvalue linearized play an important role. However, due to lack compactness, order obtain existence eigenvalue, certain additional conditions must be attached coefficients. In this paper, we approximate generalized dispersal cooperative and irreducible system, which admits Collatz-Wielandt characterization, by constructing monotonic upper lower control systems...
It is well known that, in the study of dynamical properties nonlinear reaction-diffusion systems, sign principal eigenvalue linearized system plays an important role. However, for nonlocal dispersal due to lack compactness, essential spectrum appear, and may not exist. In this paper, by constructing monotonic upper lower control we obtain generalized cooperative irreducible demonstrate that same role as usual eigenvalue.
Ocean waves represent a vast, untapped source of renewable energy, yet current wave energy harvesting technologies often struggle with efficiency, cost, and scale. Triboelectric nanogenerators (TENGs) have emerged as promising devices for mechanical harvesting, but their application in conversion remains limited by challenges design performance. Here, we present novel swing-arm triboelectric nanogenerator (SA-TENG) specifically designed harvesting. Our device employs pendulum-inspired...

An adaptive image-processing method for CT images of asphalt mixture is proposed in this paper. Different methods are compared according to the error analysis calculated between real gradation and 3D reconstruction gradation. As revealed by test results, was effective carrying out different brightness homogenization processes each image. The Wiener filter with 7 × size able produce a better noise reduction effect without compromising image sharpness. Among three methods, performed best...

Asymptomatic infection and transmission are common for quite a few directly or indirectly transmitted diseases such as COVID-19, cholera, Zika fever. In this paper, we propose susceptible-infective-asymptomatic-recovered patch model to address the influence of asymptomatic infections on spatial spread infectious diseases.

The purpose of this study is to propose a microeconomic model for optimizing government-sponsored transit incentive program, where rider receives certain monetary reward once trip completed. demand pattern considered many-to-many, which means riders travel from multiple origins destinations. Travelers are grouped by their socio-demographic characteristics and incentives can be customized each group. Analytical relations derived the optimality conditions optimization problem numerical results...
