This paper presents the first deterministic selfstabilizing network orientation algorithms. We present three protocols for arbitrary and asynchronous networks. All the protocols set up a chordal sense of direction in the network. The protocols are self-stabilizing, meaning that starting from an arbitrary state, the protocols are guaranteed to reach a state, in which all edge labels (assigned to...

We study the supergravity hybrid inflation model of Ref. [1] in the presence of a modulus field. The η-problem is solved by a shift symmetry for the inflaton, which protects the inflaton mass even in the presence of the modulus field. Inflation is (nearly) unaffected by moduli stabilization, provided the scale of supersymmetry breaking in the post-inflation vacuum is small. Therefore the model ...

We estimate the impacts of various types of government payments to U.S. agriculture on different components of farm household consumption. Using 2003 to 2005 data from the Agricultural Resource Management Survey (ARMS), we show that marginal rates of consumption differ by consumption category and income source, including different types of farm program payments. The results suggest that farm ho...

when the orbital altitude of a small satellite is near-earth, passive stabilization can be considered. the purpose of this paper is to combine the passive gravity gradient and aerodynamic stabilization methods together so that all the three axes stabilizations can be obtained. in this regard, the set of nonlinear equations of motion will be solved numerically with specified initial condition. t...

Superparamagnetic iron oxide nanoparticles (SPIONs) are widely used for biological applications due to their unique properties compared to their bulk counterparts, simplified SPIONs stabilization protocols applicable for a wide spectra of biological media remains a challenging issue. In this work, SPIONs with different surface coatings, tetramethylammonium hydroxide coated SPIONs (T-SPIONs) and...

silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...

Target-specific DNA delivery requires vectors that combine stability in the biological milieu, receptor-mediated uptake into target cells, and intracellular activation to mediate transgene expression. This is achieved here using polymer-coated vectors based on plasmid DNA complexed with a reductively degradable polycation (RPC), designed for intercellular degradation. The RPC were prepared by o...

This paper considers the quadratic stabilization problem of multi-input planar switched systems. Based on some basic lemmas, some uniformly quadratic stabilization criteria are established. Furthermore, an example is given to illustrate our results in this
