We present numerical simulation of bulk Lorentz factor of relativistic electron-positron jet driven by Compton rocket effect from accretion disc radiation. The plasma is assumed to have a power-law distribution n e (γ) ∝ γ −s whith 1 < γ < γ max and is continuously reheated to compensate for radiation losses. We include full Klein-Nishina (hereafter KN) cross section, and study the role of ener...

The efficacy of evoked ACh release by intact and newly sprouted terminals in response to partial denervation and expansion of the motor neuron terminal field was studied in mouse soleus muscle after section of the L-5 spinal root. From 2 to 4 d after partial denervation until 90 d later, only 3-7 motor units of the normal 21 remained. Regeneration of the dissected nerve was prevented while the ...

—Interconnected autonomous systems (ASs) often share security risks. However, an AS lacks the incentive to make (sufficient) security investments if the cost exceeds its own benefit even though doing that would be socially beneficial. In this paper, we develop a systematic and rigorous framework for analyzing and significantly improving the mutual security of a collection of ASs that interact f...

in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

sheep (ovine) pulmonary adenocarcinoma (spa), also known as ovine pulmonary adneomatosis (opa),jaagsiekte and ovine pulmonary carcinoma (opc) is a contagious lung tumor in sheep and, more rarely, ingoats. this study was carried out in khuzestan, in the southwest of iran for a period of six months. a totalnumber of 3985 native breed goats were clinically inspected and postmortem examination was ...

Starting in the late 1980s, financial and economic researchers became increasingly sophisticated in their attempts to analyze market expectations embedded in option prices. Moving beyond the study of implied Black-Scholes volatilities, this body of work has focused on the recovery of either the stochastic process followed by the underlying asset price or the density function from which the asse...

Assume a communication scenario in wireless ad hoc and sensor networks where each node periodically sends out status information as a 1-hop broadcast to inform neighboring nodes. These scenarios are typical for monitoring and safety related applications where each node needs information about its neighborhood, e.g., in vehicular ad hoc networks. In IEEE 802.11 based ad hoc networks, one reason ...

Decidability problems constitute one of the central topics in formal language theory. In the theory of grammatical similarity, in particular the theory of EOL forms, a lot of decidability questions arise. Some of them are proved to be decidable, e.g., m-completeness for some subclass of EOL forms (see [2] and [3]), simulations of one EOL form by another EOL form (see [6], [7] and [S]), vomplete...
