since the time man observed his picture in the water, mirror has en-tered both man’s spiritual and material life. the role of mirror has un-dergone a lot of changes, ranging from foretelling to its use by barbers in different situations, to its use as warfare, mystic allegories, literal metaphors and historical narrations such as alexander mirror located in alexandria. the present study aims to...
In this paper we study energy radiation from a moving mirror in 1+1 dimensional space-time. The mirror is assumed to have finite mass and accordingly to receive back reaction from scalar photon field. The mode expansion of the scalar field becomes different from that without back reaction though the trajectory of the mirror is not changed. Then energy density of the vacuum becomes to have finit...
Two dimensional silver(I) coordination polymer, [Ag(μ5-T4S)]n (1), (T4S- = toluene-4-sulfonate), has been synthesized and characterized by Inductively Coupled Plasma (ICP) and elemental analyses, IR spectroscopy and powder X-ray diffraction. This compound was calcined at 450, 500 and 700 °C in a furnace and static atmosphere of air. The resultin...
The radiation-reaction force F(t) acting on a moving mirror in a one-dimensional model is obtained by appeal to the fluctuation-dissipation theorem. Causality is found to provide the link between the dissipative and reactive forces; it is implemented by requirements of analyticity for the Fourier transform of the response function that links the mean force F(t) to the velocity fl(t) of the mirr...
BACKGROUND Mental rotation is a spatial representation conversion capability using an imagined object and either object or self-rotation. This capability is impaired in schizophrenia. OBJECTIVE To provide a more detailed assessment of impaired cognitive functioning in schizophrenia by comparing the electrophysiological profiles of patients with schizophrenia and controls while completing a me...
Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...
