In this Letter we present a very general method for extracting information from a generic string of characters, e.g., a text, a DNA sequence, or a time series. Based on data-compression techniques, its key point is the computation of a suitable measure of the remoteness of two bodies of knowledge. We present the implementation of the method to linguistic motivated problems, featuring highly acc...

Biocompatible highly bright silica nanoparticles were designed, prepared and tested in small living organisms for both in vivo and ex vivo imaging. The results that we report here demonstrate that they are suitable for optical imaging applications as a possible alternative to commercially available fluorescent materials including quantum dots. Moreover, the tunability of their photophysical pro...

Classical methods offer many possibilities to generate powders. Where very small particle sizes especially in spherical shape are required, or highly viscous substances have to be reduced, the limits of traditional processes are reached soon. The solution can be found in high-pressure processes. The PGSS (Particles from Gas Saturated Solutions) process e.g. is suitable for the micronisation of ...

Ambient occlusion is widely used for improving the realism of real-time lighting simulations. We present a new method for precomputed ambient occlusion, where we store and retrieve unprocessed ambient occlusion values in a 3D grid. Our method is very easy to implement, has a reasonable memory cost, and the rendering time is independent from the complexity of both the occluder and the receiving ...

We study the problem of integrated topology control and routing in Free Space Optical (FSO) mesh backbone networks. FSO links are high-bandwidth, low interference links that can be set-up very fast, making them suitable for mesh networking. FSO networks are highly constrained by interface constraints, i.e., constraints on the number of FSO links a node can establish. We prove the problem to be ...

A robust light storage and retrieval (LSR) in high dimensions is highly desirable for light and quantum information processing. However, most schemes on LSR realized up to now encounter problems due to not only dissipation, but also dispersion and diffraction, which make LSR with a very low fidelity. Here we propose a scheme to achieve a robust storage and retrieval of weak nonlinear high-dimen...

A new time-resolved fluorescence immunoassay system involving use of the europium chelate of 4,7-bis(chlorosulfophenyl)-1,10-phenanthroline-2,9-dicarboxylic acid as label is reviewed. This stable chelate by itself is not very fluorescent but, used in multiple labeling strategies, improves the achievable detection limits. By using multiple labeling, streptavidin tailing, and Eu3+ activation, one...

Lithographically fabricated iridium-based mercury microelectrode arrays are shown to be very suitable for adsorptive stripping measurements of trace nickel in the presence of the dimethylgloxime complexing agent. Variables affecting the response have been assessed and optimized. The sensor optimization has resulted in a favorable and highly stable response, with good linearity and precision (RS...

An adaptive finite element strategy is employed to solve the Perona-Malik model as modified by Catté, Lions, Morel and Coll for image processing by (often highly) nonlinear diffusion. FEMLAB® and MATLAB® are used to implement the experiments and they prove to be very suitable tools to run this type of problem. Refinement and coarsening of the grids are used as needed and the approach leads to u...

anaphylactic reactions can occur following the adminstration of muscle relaxants. however, it happens very rarefy wish pancuronium bromide. a case report of anaphylactic shock to pancuronium bromide, which is supported by a highly poitive skin prick test, is reported.
