Reconfigurability of two-dimensional colloidal crystal structures assembled by anisometric particles capable of changing their shape were studied by molecular dynamics computer simulation. We show that when particles change shape on cue, the assembled structures reconfigure into different ordered structures, structures with improved order, or more densely packed disordered structures, on faster...

We propose that cool fusion is fluctuation of the resonance which happens to the electron wave. When electricity is discharged, a special crystal is made from free particles by the tunnel phenomenon of the electron wave. If free particles line up in the arrangement of the crystal, and the particle shifts, the line makes a wave. When alignment fluctuates, phase transition occurs in crystal. Ther...

We present experimental evidence of sharp spectral features in the optical response of 2D arrays of gold nanorods. A simple coupled dipole model is used to describe the main features of the observed spectral line shape. The resonance involves an interplay between the excitation of plasmons localized on the particles and diffraction resulting from the scattering by the periodic arrangement of th...

The structure of the membranes of sarcoplasmic reticulum (SR), tubular (T) system, and sarcolemma has been studied by freeze fracture in leg muscles of the Tarantula spider. Two regions of the sarcoplasmic reticulum can be differentiated by the distribution of particles on the fracture faces: a junctional SR, at the dyads, and a longitudinal SR, elsewhere. The dyads are asymmetric junctions, th...

We give an explicit formula for all tree amplitudes in N = 4 SYM, derived by solving the recently presented supersymmetric tree-level recursion relations. The result is given in a compact, manifestly supersymmetric form and we show how to extract from it all possible component amplitudes for an arbitrary number of external particles and any arrangement of external particles and helicities. We f...

A current trend in research is the fabrication and charac terization of smaller and smaller surface structures ap proaching dimensions of a few nanometers. They are ex pected to exhibit a number of new physical and chemical properties when compared to micrometer sized structures of the same material. These can include, for example, magnetic, optical, or catalytic properties. As conventional lit...

A systematic, computational and scaling analysis of defect textures in polygonal arrangement of cylindrical particles embedded in a cholesteric (Ch) liquid crystal matrix is performed using the Landau–de Gennes model for chiral self-assembly, with strong anchoring at the particles’ surface. The defect textures and LC phases observed are investigated as a function of chirality, elastic anisotrop...

4 A drawing of a graph is pseudolinear if there is a pseudoline arrangement such that 5 each pseudoline contains exactly one edge of the drawing. The pseudolinear crossing 6 number c̃r(G) of a graph G is the minimum number of pairwise crossings of edges in 7 a pseudolinear drawing of G. We establish several facts on the pseudolinear crossing 8 number, including its computational complexity and i...

A computer code has been written which calculates the small deformation stress and strain fields of a medium consisting of a pack of rigid spherical particles embedded in an elastic Hookean matrix. The stress and strain tensors can be calculated at any point in the medium to within a user-specified accuracy. Average mechanical properties of the medium are also output by the code. The code has b...
