We use a discrete-time formulation of the asymmetric avalanche process (ASAP) [Phys. Rev. Lett. 87, 084301 (2001)]] of p particles on a finite ring of N sites to obtain an exact expression for the average avalanche size as a function of toppling probabilities and particle density rho=p/N. By mapping the model onto driven interface problems, we find that the ASAP incorporates the annealed Kardar...

The low-lying bottomoniumlike tetraquarks $b\overline{b}q\overline{q}$ ($q=u$, $d$, $s$) with spin-parity ${J}^{P}={0}^{+}$, ${1}^{+}$, and ${2}^{+}$, isospin $I=0$, 1, or $\frac{1}{2}$, are systematically investigated within the theoretical framework of real- complex-scaling range a chiral quark model, which has already been successfully applied in analysis several multiquark systems. A comple...

‎in this paper, based on [a. razani, v. rako$check{c}$evi$acute{c}$ and z. goodarzi, nonself mappings in modular spaces and common fixed point theorems, cent. eur. j. math. 2 (2010) 357-366.] a fixed point theorem for non-self contraction mapping $t$ in the modular space $x_rho$ is presented. moreover, we study a new version of krasnoseleskii's fixed point theorem for $s+t$, where $t$ is a cont...

Expression of 5 yeast mitochondrial tRNA genes (Ala, Ile, Tyr, Asn and Metm), localized upstream from the oxil gene has been analyzed by in vitro capping using guanylyltransferase, northern hybridization and S1 nuclease mapping in the wild type and a rho-strain. The 5 tRNA sequences belong to the same transcriptional unit which is initiated 133 bp upstream from the tRNA(Ala) gene at a promoter ...

BACKGROUND During vertebrate gastrulation convergence and extension (CE), movements narrow and lengthen embryonic tissues. In Xenopus and zebrafish, a noncanonical Wnt signaling pathway constitutes the vertebrate counterpart to the Drosophila planar cell polarity pathway and regulates mediolateral cell polarization underlying CE. Despite the identification of several signaling molecules require...

Thrombin induces astrocytoma cell rounding through a Rho-dependent pathway (Majumdar, M., Seasholtz, T. M., Goldstein, D., de Lanerolle, P., and Brown, J. H. (1998) J. Biol. Chem. 273, 10099-10106). The involvement of the G(12) family of G proteins and the role of specific Rho exchange factors in transducing signals from the thrombin receptor to Rho-dependent cytoskeletal responses was examined...

In this paper, we continue to consider the generalized Liouville system: $$\begin{aligned} \Delta _g u_i+\sum _{j=1}^n a_{ij}\rho _j\left( \frac{h_j e^{u_j}}{\int _M h_j e^{u_j}dV_g}- {1} \right) =0\quad \text {in }M,\quad i\in I=\{1,\ldots ,n\}, \end{aligned}$$ where (M, g) is a Riemann surface M with volume 1, $$h_1,\ldots ,h_n$$ are positive $$C^3$$ functions, $$dV_g$$ form, and $$\rho _j\in...

We carry out numerical simulations to study transport behavior about the jamming transition of a model granular material in two dimensions at zero temperature. Shear viscosity eta is computed as a function of particle volume density rho and applied shear stress sigma, for diffusively moving particles with a soft core interaction. We find an excellent scaling collapse of our data as a function o...
