Using the measure of noncompactness and Mo¨nch fixed-point theorem, we establish some sufficient conditions for controllability. Firstly, we require the equicontinuity of evolution system, and next we only suppose that the evolution system is strongly continuous. Since we do not assume that the evolution system generates a compact semigroup, our theorems extend some analogous results of (impulsive) control systems. © 2011 Elsevier Inc. All rights reserved.

The UV-vis, TEM, SAED, FTIR, DLS and XRD techniques were employed to systematically characterize Au nanocrystals synthesized. Isotropic gold nanoparticle (GNP) and gold nanoplates in good yields (up to 90%) with different sizes can be obtained easily by adjusting the experimental condition. Spherical nanoparticles were obtained with tunable mean sizes at higher pH and casein concentrations. The high colloidal stability of the spherical GNP is attributed to the formation of CM/GNP hybrid under some experimental condition. At lower pH, reaction temperature and casein concentrations, single-crystalline gold nanoplates in good yields (up to 90%) are obtained. The growth of these nanostructures is attributed to an interplay between the faceting tendency of the protein molecules/micelles and the growth kinetics. More importantly, the morphological evolution of large gold nanoplates at different reaction times has been followed, and compared with some earlier protein systems, different formation mechanisms in casein micelles are obtained. The results demonstrate that both the property of individual protein molecules and protein aggregates play important roles in controlling the formation of gold nanocrystals by using amphiphilic protein. © 2010 Elsevier B.V.

Box 3337, Columbus, OH 43210-3337, United States Abstract:An n-butanol-based nanofluid containing nanowire-shaped β-FeOOH was synthesized by a solvothermal method. The nanofluid was stable for 7 days without any precipitation with 3.0 mM SDBS as stabilizer. Uniform β-FeOOH nanowires with high aspect ratios were fabricated. The heat capacities of the obtained β-FeOOH sample, the base fluid, and the nanofluid were determined by an adiabatic calorimeter. Smoothed heat capacities and thermodynamic functions of the obtained samples, such as H(T/K) - H(298.15 K) and S(T/K) - S(298.15 K), were calculated based on the fitted polynomials and the relationships of the thermodynamic functions. These results are very useful to apply to the as-produced nanowire-shaped β-FeOOH and the nanofluid in engineering fields. © 2010 American Chemical Society.

It is essential for cell proliferation and has been proposed for treatment of various endocrine-associated diseases including growth hormone insensitivity syndrome and diabetes mellitus. In the present study, an efficient plant expression system was developed to produce biologically active recombinant hIGF-I (rhIGF-I) in transgenic rice grains.Results: The plant-codon-optimized hIGF-I was introduced into rice via Agrobacterium-mediated transformation. To enhance the stability and yield of rhIGF-I, the endoplasmic reticulum-retention signal and glutelin signal peptide were used to deliver rhIGF-I to endoplasmic reticulum for stable accumulation. We found that only glutelin signal peptide could lead to successful expression of hIGF-I and one gram of hIGF-I rice grain possessed the maximum activity level equivalent to 3.2 micro molar of commercial rhIGF-I. In vitro functional analysis showed that the rice-derived rhIGF-I was effective in inducing membrane ruffling and glucose uptake on rat skeletal muscle cells. Oral meal test with rice-containing rhIGF-I acutely reduced blood glucose levels in streptozotocin-induced and Zucker diabetic rats, whereas it had no effect in normal rats.Conclusion: Our findings provided an alternative expression system to produce large quantities of biologically active rhIGF-I. The provision of large quantity of recombinant proteins will promote further research on the therapeutic potential of rhIGF-I. © 2011 Cheung et al; licensee BioMed Central Ltd.

To investigate the dynamic characteristics of a cantilever MPF, the dynamic admittance matrix is established. It can describe the response of a cantilever MPF subjected to driving parameters, a harmonically varying axial force F at the tip and a harmonically varying voltage V on the electrodes. The responses parameters of a cantilever MPF, including a dynamic tip elongation δ and a dynamic electric charge Q, can be obtained using the vibration theory and the average distributed electrical charge method. The response parameters are related to the driving parameters by a 2 × 2 matrix. The dynamic models for measuring piezoelectric parameters of a MPF are given in order to illustrate the applications of the previous dynamic admittance matrix.

Unlike previous solutions that provide the strain and/or stress fields induced by dislocation loops, in this paper, we develop, for the first time, an approach to solve the more fundamental problem - the anisotropic elastic dislocation displacement field. By applying the point-force Greens function for a three-dimensional anisotropic elastic material, the elastic displacement induced by a dislocation of polygonal shape is derived in terms of a simple line integral. It is shown that the singularities in the integrand of this integral are all removable. The proposed expression is applied to calculate the elastic displacements of dislocations of two different fundamental shapes, i.e. triangular and hexagonal. The results show that the displacement jump across the dislocation loop surface exactly equals the assigned Burgers vector, demonstrating that the proposed approach is accurate. The dislocation-induced displacement contours are also presented, which could be used as benchmarks for future numerical studies. © 2011 Elsevier Ltd. All rights reserved.

Box 3905-9, Beijing, 100854, China Abstract:A robust dissipative control problem for a class of Itoˆtype stochastic systems is discussed with Markovian jumping parameters and time-varying delay. A memoryless state feedback dissipative controller is developed based on Lyapunov-Krasovskii functional approach such that the closed-loop system is robustly stochastically stable and weakly delay-dependent (RSSWDD) and strictly (Q, S, R)-dissipative. The sufficient condition on the existence of state feedback dissipative controller is presented by linear matrix inequality (LMI). And the desired controller can be concluded as solving a set of LMI. Finally, a numerical example is provided to demonstrate the effectiveness of the proposed approach. Number of references:18 Yüklə 2,34 Mb. Dostları ilə paylaş:
