Asset Price Dynamics with Local Interactions under Heterogeneous Beliefs
This paper investigates the effect of network structure on the asset price dynamics. We propose a simple present value discounted asset pricing model with heterogeneous agents. Every period the agents choose a predictor of the future price on the basis of past performance of their own and alternative strategies and form their demands for a risky asset. The information about the performance of an alternative strategy is available only locally from the directly connected agents. Using the rewiring procedure we produce four types of commonly considered networks: a fully connected network, a regular lattice, a small world, and a random network. The results show that the network structure influences asset price dynamics in terms of the region of stability and volatility. This is mostly due to the different speed of information transmission in the different networks.
Accelerating structure for high-gradient accelerator
The conventional TW-mode accelerating structures are usually used for high gradient linacs. But these structures grow old quickly during running. It is very serious problem for creation next linear colliders [1]. In this article brief review of defects TW-mode accelerators is presented, and circuit of an accelerator on the basis of a parallel coupled cavity structure, in which accelerating resonators fed parallel from a few waveguides, is offered
Jones matrix mapping of polycrystalline networks of layers of main types of amino acids

new products at the industrial enterprise are considered. In the process of developing new
products, the learning effect manifests itself, which leads to a reduction in labor intensity,
depending on the cumulative volume of production. The dynamic planning problem of the
production is formalized mathematically as a task of optimal control of the production system.
Two variants of managing the organizational and technical system are considered: in discrete
and continuous time. The dynamics of the system change is described by discrete and ordinary
differential equations. For the continuous problem, an analytic solution is obtained using the
Pontryagin maximum principle.ΠΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠ΅ Π²ΡΠΏΠΎΠ»Π½Π΅Π½ΠΎ ΠΏΡΠΈ ΡΠΈΠ½Π°Π½ΡΠΎΠ²ΠΎΠΉ ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠΊΠ΅ Π Π€Π€Π ΠΈ Π‘Π°ΠΌΠ°ΡΡΠΊΠΎΠΉ ΠΎΠ±Π»Π°ΡΡΠΈ Π² ΡΠ°ΠΌΠΊΠ°Ρ

Wavelet-analysis of gastric microcirculation in rats with ulcer bleedings
Nitric oxide (NO) plays an important role in regulation of central and peripheral circulation in normal state and during hemorrhagic stress. Because the impaired gastric mucosal blood flow is the major cause of gastroduodenal lesions including ulcer bleeding (UB), we study in this work the NO-ergic mechanism responsible for regulation of this blood flow. Our study is performed in rats with a model of stress-induced UB using laser Doppler flowmetry (LDF) that characterizes the rate of blood flow by measuring a Doppler shift of the laser beam scattered by the moving red blood cells. Numerical analysis of LDF-data is based on the discrete wavelet-transform (DWT) using Daubechies wavelets aiming to quantify influences of NO on the gastric microcirculation. We show that the stress-induced UB is associated with an increased level of NO in the gastric tissue and a stronger vascular sensitivity to pharmacological modulation of NO-production by L-NAME. We demonstrate that wavelet-based analyses of NO-dependent regulation of gastric microcirculation can provide an effective endoscopic diagnostics of a risk of UB
