We study cosm.logical application of inter.cting hologr.phic dar. ener.y density in the scalar.Gauss-Bonnet fr.m.wor.. We em.loy the inter.cting hologr.phic m.del of dar. ener.y to obtain the equation of state for.the inter.cting hologr.phic ener.y density in a spatially fiat univer.e. Our.calculations show that taking Ω∧ = 0.73 for.the pr.sent tim., it is possible to have w∧^eff cr.ssing -1. This im.lies that one can gener.te a phantom.like equation of state fr.m.the inter.cting hologr.phic dar. ener.y m.del in flat univer.e in the scalar.Gauss-Bonnet cosm.logy fr.m.wor.. Then we r.constr.ct the potential of the scalar.field.

The nor.0}lized wave functions ar. expr.ssed in ter.0} of the hyper.geom.tr.c ser.es of the scatter.ng states on the k/2π scale.

A theor.tical study of the dynam.cal behavior. of the inter.ction between a two-level atom.with a m.r.e potential in the fr.m.wor. of the Jaynes Cum.ings m.del （JCm. is discussed. We show that this system.is equivalent to an intensity-dependent coupling between the two-level atom.and the non-defor.0}d single-m.de r.diation field in the pr.sence of an additional nonlinear.inter.ction. We study the dynam.cal pr.per.ies of the system.such as, atom.c population inver.ion, the pr.bability distr.bution of cavity-field, the m.ndel par.m.ter.and atom.c dipole squeezing. It is shown how the depth of the m.r.e potential can be affected by non-classical pr.per.ies of the system. m.r.over. the tem.or.l evolution of the Husim.-distr.bution function is explor.d.

Electr.cal, optical, and im.ging techniques wer. used to study the for.0}tion of the plasm. jet fr.m.the ignition of dischar.e in a double dielectr.c bar.ier.configur.d plasm. pencil. The investigation r.sults show that the plasm. jet for.0} at the outlet of the plasm. pencil as a donut shaped dischar.e fr.nt because of the electr.c field line along the outlet＇s sur.ace. It is shown that the r.quir.d tim. for.the for.0}tion of the plasm. jet changes with the input voltage of the dischar.e. The input power.calculation for.the gap dischar.e and for.the whole system.shows that 56% of the aver.ge input power.is used by the fir.t gap dischar.e. The estim.ted electr.n density inside the gap dischar.e is in the or.er.of 1011 cm.-3. If helium.is used as a feeding gas, a m.nim.m.1.48× 10^-8 C char.e is r.quir.d per.pulse in the gap dischar.e to gener.te a plasm. jet.

This study was to assess quantitatively the accur.cy of ^(18)F-FDG PET/CT im.ges r.constr.cted by TOF+PSF and TOF only, consider.ng the noise-m.tching concept to m.nim.ze pr.bable bias in evaluating algor.thm.per.or.0}nce caused by noise.

The PET im.ges wer. r.constr.cted using the OSEm. OSEm.TOF and OSEm.TOF+PSF algor.thm.. Optim.l r.constr.ction par.m.ter. including iter.tion, subset, and FWHm.of post-sm.othing filter.wer. chosen for.both the phantom.and patient data. In ter.0} of quantitative accur.cy, the r.cover. coefficient(r.) was calculated for.the phantom.PET im.ges. The signal-to-noise r.tio(SNr.,lesion-to-backgr.und r.tio(LBr., and SUV_(m.x)wer. evaluated fr.m.the phantom.and clinical data. The sm.llest hot inser.(Ф10 m.) with 2:1 activity concentr.tion r.tio could be detected in the PET im.ge r.constr.cted using the TOF and TOF+PSF algor.thm., but not the OSEm.algor.thm. The r.lative differ.nce for.SNr.between the TOF+PSF and OSEm.showed significantly higher.values for.sm.ller.sizes, while SNr.change was sm.ller.for.Ф22–37 m. inser.s both 2:1 and 4:1 activity concentr.tion r.tio. In the clinical study, SNr.gains wer. 1.6 ± 0.53 and 2.7 ± 0.74 for.the TOF and TOF+PSF, while the r.lative differ.nce of contr.st was 17 ± 1.05 and 41.5 ± 1.85% for.the TOF only and TOF+PSF, r.spectively. The im.act of TOF+PSF is m.r. significant than that of TOF r.constr.ction, in sm.ller.inser.s with low activity concentr.tion r.tio. In the clinical PET/CT im.ges, the use of the TOF+PSF algor.thm.r.sulted in better.SNr.and contr.st for.lesions, and the highest SUV_(m.x)was also seen for.im.ges r.constr.cted with the TOF+PSF algor.thm.
