in this paper, a method for automatic stitching of radiology images based on pixel features has been presented. in this method, according to the smooth texture of radiological images and in order to increase the number of the extracted features after quality enhancement of initial radiology images, 45 degree isotropic mask is applied to each radiology image to observe the image details. after t...

A calculation of the inclusive spectra pions and kaons produced in pp collisions as functions their transverse momentum $$p_T$$ at mid-rapidity is presented within self-similarity approach. satisfactory description data a wide range initial energies presented. We focus mainly on ratio cross-sections $$K^\pm $$ to $$\pi ^\pm mesons function $$\sqrt{s}$$ . fast rise this ratio, when energy increa...

Both backward masking and transcranial magnetic stimulation (TMS) are capable of hindering perception of a visual target. To study the relationship between these two methods we applied TMS over the occipital pole in combination with the visual backward masking technique shine-through. The recently discovered weak shine-through mask consists of a horizontal grating with 25 vernier elements. In t...

1. Vitamin D-Defficiency or Infantile Rickets: This is extremely rare in the Sudan owing to the availability of sun-shine throughout the year. Since infantile rickets is common in some other African countries where sun-shine is also constant throughout the year, other factors, which obstruct the natural ultraviolet irradiation e.g. crowded housing and overprotection of infants must be operating...

Replication of the IncB miniplasmid pMU720 requires synthesis of the replication initiator protein, RepA, whose translation is coupled to that of a leader peptide, RepB. The unusual feature of this system is that translational coupling in repBA has to be activated by the formation of a pseudoknot immediately upstream of the repA Shine-Dalgarno sequence. A small antisense RNA, RNAI, controls rep...
