In the present paper, we provide results and discussions concerning the processes that lead to local and global chaotic diffusion in the phase space of multidimensional conservative systems. We investigate and provide a measure of the extent of the domain over which diffusion may occur. All these issues are thoroughly discussed by dealing with a multidimensional conservative map that would be r...

This paper argues that the reason that the DSGE model, which has proved so successful in convincing academic economists of its value, has made relatively few inroads into the undergraduate teaching sphere is that it fails to allow for the development of higher order educational objectives in students. The qualities which make it attractive to academics, such as the purity of its assumptions and...

We examine the possibility that SUSY particles are light, i.e. have a mass just beyond the final kinematical reach of LEP2. In this case, even if light particles are not directly detected, their virtual effects are enhanced by a “close to threshold” resonance in the s-channel. We find that this resonant effect is absent in the case of light sfermions, while it is enhanced in the case of light g...

We consider decays of the lowest-lying radially excited baryons. Assuming a single-quark decay approximation , and negligible configuration mixing, we make model-independent predictions for the partial decay widths to final states with a single meson. Masses of unobserved states are predicted using an old mass formula rederived using large-Nc QCD. The momentum dependence of the one-body decay a...

A weakly coupled new neutral gauge boson, forming a narrow resonance, can be efficiently produced at ee colliders through radiative return processes if the collider energy is larger than the gauge boson mass. This contribution analyzes the sensitivity of a future linear collider for weakly coupled gauge bosons and briefly discusses how, in case of discovery, its properties can be determined wit...

-Calibration of the spatial sensitivity functions of coil arrays is a crucial element in parallel magnetic resonance imaging (PMRI).In order to overcome the sensitivity miscalibration errors introduced by pre-scan calibration method and decrease the total examination time, a new self-calibrating method for estimating the coil sensitivity profiles was proposed in the paper. From a fullysampled c...

We propose a technical solution that enables 3D video-based in-bore movement quantification to be acquired synchronously with the BOLD function magnetic resonance imaging (fMRI) sequences. Our solution relies on in-bore video setup with 2 cameras mounted in a 90 degrees angle that allows tracking movments while acquiring fMRI sequences. In this study we show that using 3D motion quantification ...

I present the results of a recent calculation to determine the number of strange scalar resonances below 1.8 GeV based on the analytic properties of the experimental πK scattering amplitude. Only one resonance was found in the data, and this is readily identifiable as the K * 0 (1430). We found no evidence to support the κ(900).

We present a quark model study of the ω meson photoproduction near threshold. With a limited number of parameters, all the data in history are reproduced. The roles played by the sand u-channel processes (resonance excitations and nucleon pole terms), as well as the t-channel natural (Pomeron) and unnatural parity (pion) exchanges are clarified. This approach provides a framework for systematic...
