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 recent years, natural substances such as zeolite have been used to absorb heavy metals in soil in an attempt to decrease their availability to plants. Compared to other techniques, the use of zeolite is fast, clean, and inexpensive. This research was carried out to investigate the effects of an Iranian natural zeolite (clinoptilolite) on stabilizing Cd-contaminated soil treated with 0.01 M C...

Biomechanical studies of human walking reveal that compliance plays an important role at least in natural and smooth motions as well as for self-stabilization. Inspired by this, we present here the development of a new lower leg segment of the dynamic biped robot “RunBot”. This new lower leg segment features a compliant ankle connected to a flat foot. It is mainly employed to realize robust sel...

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...

Horizontal gene transfer allows rapid spread of antibiotic resistance genes1, which in bacteria inhabiting natural aquatic systems occurs by conjugation, transduction, and transformation2. Natural genetic transformation is characterized by the uptake of free DNA by a recipient bacterium, its chromosomal integration or extrachromosomal stabilization, and its expression, which leads to a new phen...

The goal of this study was to investigate the human ability to stabilize the trunk in space during pelvic tilt. Upper body sway was evoked in kneeling-seated healthy subjects by angular platform perturbations with a rotation around a virtual low-back pivot point between the L4 and L5 vertebrae. To investigate motor control modulation, variations in task instruction (balance naturally or minimiz...
