In this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. And generalize weakly Zamfirescu map in to modified weakly Zamfirescu map.

banach contraction principle has been generalized in different spaces by mathematicians over the years. mustafa and sims [18] proposed a new class of generalized metric spaces, which are called as g-metric spaces. in this type of spaces a non-negative real number is assigned to every triplet of elements. many mathematicians studied extensively various results on g-metric spaces by using the con...

due to successes of fingerprinting method in producing rapid and low-cost information of sediment sources, in this research this method was used in three sub-cathments of chasht-khoran basin in semnan province: amrovan, atari and ali-abad. samples below 63 μm were separated and 15 fingerprinting propertis was measured. in the first stage comparison of means and differentiation analysis were use...

The confinement of Ag(111) surface-state electrons by self-assembled, nanoporous metal-organic networks is studied using low-temperature scanning tunneling microscopy and spectroscopy as well as electronic structure calculations. The honeycomb networks of Co metal centers and dicarbonitrile-oligophenyl linkers induce surface resonance states confined in the cavities with a tunable energy level ...

First-principles calculations have been performed in order to determine effective exchange integrals between strongly and weakly exchange-biased Co monolayers in the modulated CoCu 2 /CoCu n superlattices. For 3 ≤ n ≤ 6 it has been found that the respective exchange integrals have opposite signs and differ for n = 4 from each other by one order of magnitude and for n = 4 still by a factor of ∼ ...

Weakly-supervised object detection attempts to limit the amount of supervision by dispensing need for bounding boxes, but still assumes image-level labels on entire training set. In this work, we study problem an detector from one or few images with and a larger set completely unlabeled images. This is extreme case semi-supervised learning where labeled data are not enough bootstrap detector. O...

The magnetic circular dichroism of the d-d transitions of Co(I1) when substituted for Zn(I1) in the Zn(II)-Cu(I1) enzyme bovine superoxide dismutase enzyme is reported. Magnetic circular dkhroism of the Co(I1) chromophore in the Co(II)-Cu(I1) enzyme is typical of tetrahedral Co(I1) compounds. The magnetic circular dichroism band pattern is almost identical with the magnetic circular dichroism o...
