We establish a common fixed point theorem for weakly compatible mappings generalizing a result of Khan and Kubiaczyk 1988. Also, an example is given to support our generalization. We also prove common fixed point theorems for weakly compatible mappings in metric and compact metric spaces.
In an attempt to elucidate the potential of premeiotic male germ cells to malignant transformation both the invasiveness and the differential gene expression of several putative tumor markers of the spermatogonia-derived cell line GC-1spg and the spermatocyte-derived cell line GC-4spc were analyzed. Studies, using RT-PCR analysis, of the expression pattern… (More)
The problem of the parameterization of data points in NURBS curve/surface has been considered by amount of researchers. In this study, a new parameterization method considered as hybrid parameterization method is proposed. Like universal method, this method uses the property of ¿at each span index, there is exactly one maximum value of the rational B-spline… (More)
The genes Phf5a and Phf5b-ps are the first two members of a novel murine multigene family that is highly conserved during evolution and belongs to the superfamily of PHD-finger genes. The Phf5 gene family contains an active locus on mouse chromosome 15, region E and several processed pseudogenes on different chromosomes. The active locus, Phf5a, is… (More)
In 1916, Tricomi 1 introduced originally the concept of quasi-nonexpansive for real functions. Subsequently, this concept has studied for mappings in Banach and metric spaces see, e.g., 2–7 . Recently, some generalized types of quasi-nonexpansive mappings in metric and Banach spaces have appeared. For example, see Ahmed and Zeyada 8 , Qihou 9–11 and others.… (More)
In the present paper, we prove some fixed point theorems of Hegedus contraction in some types of distance spaces, dislocated metric space, left dislocated metric space, right dislocated metric space and dislocated quasi-metric metric space which are generalized metrics spaces where self-distances are not necessarily zero.
Accident forecasting is designed to help decision making and planning before loss occur; a new method of combination forecasting applied in traffic accident is showed in this paper. It is based on the rough sets theory, and the weighting coefficient of all the forecast models, so the result of forecasting will be more precise. Based on the mean relative… (More)
In this paper, the problem of reducing control points for surface reconstruction is addressed. A new parameterization method considered as hybrid method for NURBS surface is presented. This method allows multiple knots, and very close domain knots. The proposed method and another three conventional methods (uniform, cord length and centripetal) are applied… (More)
3T3-L1 preadipocytes undergo adipogenesis in response to treatment with dexamethaxone, 1-methyl-3-isobutylxanthine, and insulin (DMI) through activation of several adipogenic transcription factors. Many autophagy-related proteins are also highly activated in the earlier stages of adipogenesis, and the LC3 conjugation system is required for formation of… (More)
