For the sake of achieving remarkable superprism effect, we investigate in thin film Fabry-Perot filter which possess drastic change in phase and large group delay around wavelength of peak transmittance. The group delay and spatial dispersion shift are simulated numerically; while the device is fabricated and tested with the maximum spatial separation shift reach to 65μm. We also analyze Gaussi...

The global dynamical properties of a quantum system can be conveniently visualized in phase space by means of a quantum phase space entropy in analogy to a Poincaré section in classical dynamics for two-dimensional time-independent systems. Numerical results for the Pullen–Edmonds systems demonstrate the properties of the method for systems with mixed chaotic and regular dynamics.

In this article, we investigate how accurately the squared error captures perceptual errors introduced by Fourier phase spectrum changes. We measure the perceptual error using the Auditory Image Model by Patterson et al.. The squared error is found to represent the perceptual error well for low squared errors but it saturates. Thus, a further increase in squared error does on average not lead t...

I propose to study the impact of national cultural differences on knowledge sharing activities in global virtual teams. Specially, I will put the research in a specific context of Chinese culture and the U.S. culture. Only Chinese perceptions of the impact of cultural differences between China and the U.S. will be studied. I propose to use a two-phase study. In phase one, an exploratory case st...

Purpose: The sensorimotor cortex oscillations (frequency ranging between 12 and 15 Hz), commonly known as Sensorimotor Rhythm (SMR) has previously displayed a promising link between the performance of the visuomotor related to skill execution and part of psychology that is adaptive (e.g. the process linked attention which is automatic). This study examined the extent of SMR power in the executi...

Mouse oocytes were placed in Hepes-T6 containing 7.5 μg/ml cytochalasin B and 5μg/ml Hoechst prior to enucleation, and enucleation was performed on oocytes using the manipulator. The oocyte held in place by gentle suction of a holding pipette (oocyte diameter approx.70 μm). The metaphase spindle (arrow) is aspirated into an enucleation pipette (1).

background: to investigate the status of the nuclear medicine (nm) centers in iran for the performance of dose calibrators, 18 out of 54 centers providing nm services in iran were randomly selected and inspected in 1997. in the first phase of the study the selected centers were inspected for performing of quality control (qc) tests of dose calibrators. the linearity of the activity response, pr...
