Invariance of the effective action under changes of the renormalization scale μ leads to relations between those (presumably calculated) terms independent of μ at a given order of perturbation theory and those higher order terms dependent on logarithms of μ. This relationship leads to differential equations for a sequence of functions, the solutions of which give closed form expressions for the...

A capacitive coupling structure is developed to improve the performances of a capacitive complementary metal oxide semiconductor (CMOS) microelectromechanical system (MEMS) humidity sensor. The humidity sensor was fabricated by a post-CMOS process. Silver nanowires were dispersed onto the top of a conventional interdigitated capacitive structure to form a coupling electrode. Unlike a convention...

The model for the QCD analytic running coupling, proposed recently, is extended to the timelike region. This running coupling naturally arises under unification of the analytic approach to QCD and the renormalization group (RG) formalism. A new method for determining the coefficients of the “analytized” RG equation is elaborated. It enables one to take into account the higher loop contributions...

This paper deals with the theoretical investigation of the thermal instability of a thin layer of electrically conducting micropolar rotating fluid, heated from below in the presence of uniform vertical magnetic field in porous medium. A dispersion relation is obtained for a flat fluid layer, contained between two free boundaries using a linear stability analysis theory, and normal mode analysi...

In this paper, we study chaotic synchronization in lattices of coupled Lorenz equations with Neumann or periodic boundary condition. Three different coupling configurations in the single xi-, yior zi-component are considered. Synchronization is affected by coupling rules. We prove that synchronization occurs for either xior yi-component coupling provided the coupling coefficient is sufficiently...

Photonic routing has been attracting much interest to overcome the bottleneck of routing function in the broadband networks. This paper investigates theoretically the performance of an integrated-optic circuit for recognition of optical quadrature phase shift keying (QPSK) coded labels in photonic router. The analysis takes into account the effect of system impairments such as waveguide loss an...

Electrical coupling between some subclasses of interneurons is thought to promote coordinated firing that generates rhythmic synchronous activity in cortical regions. Synaptic activity of cholecystokinin (CCK) interneurons which co-express cannabinoid type-1 (CB1) receptors are powerful modulators of network activity via the actions of endocannabinoids. We investigated the modulatory actions of...

We report the theoretical and experimental study of a temperature sensor based on the changing of the refractive index with the temperature in double core optical fibre. Because of it the coupling coefficient between two cores depends on temperature. This sensor uses the double core fibre directly as a temperature sensor as well to a data transmission. The influence of variations of the tempera...

In this study, propagation characteristics of surface acoustic waves in a layered piezoelectric structure (AlN/128°Y-X LiNbO3) are investigated. The phase velocity and coupling coefficient of the layered structure with interdigital transducers and/or metal thin films deposited at various interfaces will be calculated numerically. The effects of the polarity of 128°Y-X LiNbO3 on SAW characterist...

We reconsider the nonlinear resonant interaction between three electrostatic waves in a magnetized plasma. The general coupling coefficients derived from kinetic theory are reduced here to the low-frequency limit. The main contribution to the coupling coefficient we find in this way agrees with the coefficient recently presented in Annales Geophysicae. But we also deduce another contribution wh...
