We analyze the phase diagram in effective chiral quark models (the Nambu– Jona-Lasinio model, the σ-model with quarks) and show that at the mean-field level a phase with a periodically-modulated chiral fields separates the usual phases with broken and restored chiral symmetry. A possible signal of such a phase is the production of multipion jets travelling in opposite directions, with individua...

We propose a linear compression technique for the time interval distribution of photon pairs. Using a partially frequency-entangled two-photon (TP) state with appropriate mean time width, the compressed TP time interval width can be kept in the minimum limit set by the phase modulation, and is independent of its initial width. As a result of this effect, ultra-narrow TP time interval distributi...

In the following we will desefibe a PC based system which allows motor disabled persons to control devices in a domestic environment. The system will be able to "learn" and reproduce infrared (IR) code from virtually every IR controller currently available, so it can relay on a wide range of commercial devices, now and in the future. The configuration phase will be quite easy, enabling non-expe...

Resonances appearing in hadronic scattering processes are described by a two-phase model. In the one phase, scattering products are observed, whereas the other phase describes confinement. A so-called “Resonance-Spectrum Expansion” is derived, containing expressions that resemble Breit-Wigner formulae. This method also provides a straightforward explanation for the origin of the light scalar me...

Forecasting warranty claims for recently launched products that have short histories of claim records is vitally important for manufacturers in preparing their fiscal plans. Since the amount of historical claim data for such products is not large enough, developing forecasting models with good performance has been a difficult problem. The objective of this paper is to develop an algorithm for f...

This document is meant to help individuals use the Cerebral Signal Phase Analysis toolbox which implements different methods for estimating the instantaneous phase and frequency of a signal and calculating some related popular quantities. The toolbox – which is distributed under the terms of the GNU GENERAL PUBLIC LICENSE as a set of MATLAB R © routines – can be downloaded at the address http:/...

The use of a phase plate in electron microscopy has shown renewed interest, triggered by a publication on this topic in 2001 by Danev and Nagayama [1]. This interest can be understood from the fact that many samples that are studied in TEM are weak phase objects. The use of a phase plate is the obvious method of choice to convert otherwise invisible phase modulations into visible amplitude modu...
