We consider dilaton stabilization with R invariance, which insures a vanishing cosmological constant at the scale of stabilization. We construct a few models which accommodate weak gauge couplings with large or small gauge groups. Matter condensation plays a central role in the dilaton stabilization.

Kutten and Patt-Shamir have proposed a method for fast recovery of the output of a non-reactive, distributed protocol: if f < n=2 processors are corrupted from a legitimate global state, then the method recovers the output in O(f) time. The proposed method leaves open the case f n=2. This note presents a technique to handle also the case of f n=2, again recovering the output in O(f) time. The r...

A randomized uniform self-stabilizing protocol that provides each (anonymous) processor of a uniform system with a distinct identiier is presented. The protocol uses a predeened xed amount of memory and stabilizes within expected (d) time, where d is the actual diameter of the network.

in the present paper, a landslide and its stabilization is studied on a slope of tabriz northern freeway. this landslide is a large scale one, and as the study zone has a sliding potential so that its study is quite necessary. the analysis of landslide has been performed using stabl software. the way of obtaining the critical slope for land slide amongst different sections and determining a suc...

We have conducted some simulations of biological pathways with hybrid functional Petri net (HFPN) after careful reading of papers and developed a powerful simulation tool “Cell Illustrator [5]” (CI) for representing biological pathways with HFPN. In this study, by using CI, we constructed pathway of CDK-dependent phosphorylation pathway and ARF-dependent pathway, to observe the effect of the ph...

Three biomimetic machines are presented: an external knee prosthesis, a bipedal robot, and a robotic fish. Here we demonstrate how models of biological movement and actuators that perform like muscle can enhance machine stability, efficiency and dynamic cosmesis. Ideas addressed in the paper include the use of muscle tissue for machine actuation, and how biological models can serve as virtual c...

liposomes as a drug carrier have numerous dominancy. liophilization is the most propr form of these products for long-term maintenance, but this procedure is affected by unstabilizing agent that results in destruction of membrane, release of content and change in size and microbial contamination hence for prevention of the adverse effects, the protective role of sugars such as: maltose, fructos...
