Flexibility is a concept associated with variable needs of human beings.Today transformable structures are used to meet human changeable demands with different purposes and functions such as facades, roofs, sunshades, etc.A Flexible structure must be able to change physically and adapt to predetermined conditions.To provide flexibility and adaptability,transformable systems are required to poss...

We explore the nonlinear dynamics of a forced core-mantle system. We show that the free axisymmetric motion of a uniform-vorticity Ñuid core coupled to a rigid mantle (the model) is Poincare -Hough integrable. We derive an approximate Hamiltonian for the core tilt mode that includes the leading nonlinear contribution. We then include gravitational perturbations in the analysis. We identify the...

The asymptotic structure of outflows from rotating magnetized objects confined by a uniform external pressure is calculated. The flow is assumed to be perfect MHD, polytropic, axisymmetric and stationary. The well known associated first integrals together with the confining external pressure, which is taken to be independent of the distance to the source, determine the asymptotic structure. The...

Core elements of cell regulation are made up of protein-protein interaction (PPI) networks. However, many parts of the cell regulatory systems include unknown PPIs. To approach this problem, we have developed a computational method of high-throughput PPI network prediction based on all-to-all rigid-body docking of protein tertiary structures. The prediction system accepts a set of data comprisi...

We succeeded recently in developing a series of new pathways to polymeric micelles and hollow spheres via intermolecular specific interactions. A new micellization mechanism of block copolymers was realized by using the specific interaction between a low molecular weight compound and one of the blocks in low-polarity solvents. Many more successes have been achieved by our "block copolymer-free"...

Rammed Earth (RE) is enjoying a renewed interest in North America. Contemporary stabilized rammed earth (SRE) builds upon traditional RE and incorporates rigid insulation and reinforcing steel, enhancing the structural and energy performance of the walls while satisfying current building codes. RE structures are currently engineered by licensed Structural Engineers using the Concrete Building C...

We describe a new mesoscopic model of oligonucleosomes that incorporates flexible histone tails. The nucleosome cores are modeled using the discrete surface-charge optimization model, which treats the nucleosome as an electrostatic surface represented by hundreds of point charges; the linker DNAs are treated using a discrete elastic chain model; and the histone tails are modeled using a bead/ch...

Concentration profiles on the different sites of tungsten screw dislocation are calculated as a function nominal carbon atom concentration, temperature and density. Rigid lattice Monte Carlo simulations associated mean-field modelling performed based interaction energies from ab initio calculations. We show that repulsive interactions induce ordering phenomena drastically change concentration i...

Within the last decade columnar discotic liquid crystals (DLCs) have attracted considerable interest, not least for their potential technological applications as one-dimensional conductors, in sensors, field-effect transistors, and photovoltaic solar cells. The coupling within stacked polyaromatic cores provides an efficient structure for charge transport along the columns thus providing one-di...

For many clinical applications, non-rigid registration of medical images demands cost-effective high performance solutions in order to be usable. We present a parallel design and implementation of a wellknown algorithm based on mutual information and a B-Spline transformation model for the Cell Broadband Engine(Cell/B.E.) platform. It exploits the different levels of parallelism offered by this...
