The maximal evolution speed of any quantum system can be expressed by the quantum speed limit *** this paper,we consider a model in which the system has a correlation with the *** influence of the initial correlation between the system and environment on the quantum speed limit is *** is shown that the appearance of non-Markovianity effects causes the speedup of quantum ***,we demonstrate the dependence of quantum dynamical speedup on the quantum coherence of the correlated initial state.

We investigated the floristic composition of the Hyrcanian forests and the related forest-steppe ecotone in Northern Iran by using two long ecological transects, from lowland to upper mountain areas. The study was conducted during 2008 and 2009 and yielded the identification of 395 plant taxa belonging to 233 genera and 78 families. Dicots with 300 taxa were the richest groups of the flora, followed by monocots with 75 taxa, pteridophytes with 18 species,and gymnosperms with two species. The largest families were Asteraceae（33 taxa）; Rosaceae（32 taxa）; and Poaceae（30 taxa）, and the most diverse genera included Carex（15 taxa）; Alchemilla（7 taxa）; and Poa, Geranium and Acer（6 taxa each）. Hemicryptophytes were the most dominant life forms in the area（40 %）; followed by geophytes（31.4 %）; phanerophytes（15.4 %）; therophytes（11.4 %）; and chamaephytes（1.8 %）. Phytogeographically,Euro-Siberian/Irano-Turanian elements（86 taxa, 21.8 %）and Euro-Siberian elements（85 taxa, 21.5 %） were the most common chorotypes in the area. Out of 395 taxa, 66taxa（16.7 %） were endemics and subendemics in Iran, of which 26 taxa were exclusively endemics of *** to the IUCN Red List Categories, 48 threatened plant taxa were found in the study area. Plant diversity, life form, and chorotypes in the current study were compared with similar transect studies in other areas of the Hyrcanian forests and in different altitudinal belts, using S？renson similarity indices. Floristic composition of the surveyed transects demonstrated almost 50 % similarity between them.

AIM:To investigate effects of anti-TNF biologic drugs on uveitis severity(comparing visual acuity log MAR levels) in Behcet ***:Three databases Pub Med, Scopus, and the Web of Science were searched for qualified papers focusing on the anti-TNF-α factors treatment in Behcet’s disease(BD)-associated uveitis. Studies that were designed pre and post anti-TNF drug treatment, were selected. After determining the search strategy for this study, the relevant data were extracted. RESULTS:The initial search was performed in the target databases and a total of about 1458 articles were found. Fifteen articles were selected for systematic review and only 12 of them had inclusion criteria for Meta-analysis(with visual acuity data). The mean dose of prednisolone before and after biological treatments was reported in 5 studies(28.56 and 7.56 mg/kg, respectively). Also, the preliminary results indicate a significant reduction in visual acuity log MAR levels(MD=-1.5 IU/L, 95%CI:-2.1,-0.01).CONCLUSION:Biological drugs significantly reduce the dose of prednisolone and affect visual acuity values.
