Subsequently, various approaches to the problem have been introduced by several authors.
Different iterative schemes have been introduced by several authors to approximate the fixed points of nonexpansive mappings (see, for example, [3 5]).
In recent years, many treatment functions have been introduced by several authors to study some epidemic models under different conditions (see, for instance, [12, 14, 27, 31, 35 38]).
To meet the current demands for rapid DNA amplification, various instruments and innovative technologies have been introduced by several groups in recent years.
For instance, high performance photocatalysts such as carbon nanotube-TiO2 [12 14], fullerene-TiO2 (C60-TiO2) [15 17], and graphene-TiO2 [19] 19] composites have been introduced by several groups and have shown enhanced photocatalytic activities.
Thus, the GROV/WYOV common ancestor might have been introduced by several different means during the transport of persons, supplies, or both.
A comparison of these LPS loci indicates that the ancestor of all X. oryzae pathovars is likely to have had an LPS locus that is related to the corresponding locus in Xac with variations in the X. oryzae lineage being introduced by several largescale HGT events.
However intraoperative radiation therapy has been introduced by several groups including ours also in the treatment of extremity tumors [ 13- 16] to replace the external beam boost mainly because of its unique opportunity to guide a high single dose directly to the high risk region for close or positive margins under visual control during surgery.
Later on, the use of ventriculography to delineate the ac pc line in monkey surgery (in the same way as conducted in humans by this time) was introduced by several groups (Percheron and Lacourly 1973, Féger et al. 1975, Ilinsky and Kultas-Ilinsky 1982), and therefore, the availability of a stereotaxic atlas based on internal landmarks and the ac pc line became an urgent need (Dubach et al. 1985).
To account for possible non-parameteric relationships (as might be introduced by the high values of several data points) we also performed a Spearman's rank correlation (which mitigates the influence of extreme values by assessing the correlation of nominal ranks rather than actual raw values).
