A general and an arbitrarily efficient scheme for entangling the spins (or any spinlike degree of freedom) of two independent uncorrelated identical particles by a combination of two particle interferometry and which way detection is formulated. It is shown that the same setup could be used to identify the quantum statistics of the incident particles from either the sign or the magnitude of mea...

We present a new method for the imaging of single metallic nanoparticles that provides information about their shape and orientation. Using confocal microscopy in combination with higher order laser modes, scattering images of individual particles are recorded. Gold nanospheres and nonorods render characteristic patterns reflecting the different particle geometries. In the case of nanorods, the...

A novel process for obtaining controlled morphologies in polymer blends is modeled numerically. Particles of one type of polymer are allowed to dissolve in a matrix of a dissimilar polymer. Prior to complete dissolution the blend is quenched into the two-phase region, such that phase separation takes place. The combination of the incomplete dissolution and the wavelength selection process assoc...

A comprehensive mathematical model based on the discrete particle model and computational fluid dynamics was utilized to investigate mixing and segregation of particles in fluidized beds at high pressure. To quantify the extent of mixing in the bed, the Lacey mixing index was used. Simulations were carried out with different mass fractions of small particles at various pressures ranging from 1 ...

Two novel particle swarm optimization (PSO) algorithms are used to track and optimize a 3dimensional parabolic benchmark function where the optimum location changes randomly and with high severity. The new algorithms are based on an analogy of electrostatic energy with charged particles. For comparison, the same experiment is performed with a conventional PSO algorithm. It is found that the bes...

In the perfect off-lattice DLA model of the fractal growth the centre-attractive drift factor and mobility of particles are introduced. Simulation indicates variation of fractal patterns and their characteristics depending on these new factors. Noticeable effects of the drift factor upon fractal dimension, growth efficiency and frozen zone are shown. The mobility behaves in the competitive mann...

Interferometric position detection of levitated particles is crucial for the centre-of-mass (CM) motion cooling and manipulation of levitated particles. In combination with balanced detection and feedback cooling, this system has provided picometer scale position sensitivity, zeptonewton force detection, and sub-millikelvin CM temperatures. In this article, we develop an analytical model of thi...

This communication describes the co-assembly of polydopamine spheres, either bare or coated with Fe3O4 magnetic nanoparticles, with the short aromatic peptide diphenylalanine. The combination of polydopamine particles and diphenylalanine generated tubular structures decorated with adhesive spherical particles, while the co-assembly of the polydopamine spheres coated with magnetic Fe3O4 nanopart...

Zusammenfassung Während Java Threads (Aktivitätsstränge) als geeignetes Sprachmittel für die Programmierung von SMPs (Parallelrechnern mit gemeinsamem Speicher) anbietet, fehlen elegante und ausreichende Sprachmittel für die Programmierung von Parallelrechnern mit verteiltem Speicher (DMPs), also auch für Cluster von Arbeitsplatzrechnern. Die in der Java-Distribution angebotene explizite Socket...
