Recommended by Radu Precup The boundedness and compactness of the weighted composition operators from logarithmic Bloch-type spaces to Bloch-type spaces are studied here.

In the pre-era of Global Navigation Satellite System (GNSS), Astronomy was only technique available for determination position or Azimuth. Still, to understand space-based technique, a good knowledge is necessary; concept Celestial Sphere, Coordinates Bodies, and various categories Time. The celestial coordinate systems are based on fixed point in space, Vernal Equinox First Point Aries(γ). Thi...

decade, I am as disappointed with negative results as you are. However, those results cannot be wiped out because of the technicalities you mention (and which we disagree with, as mentioned above). As Sun Tzu says in the Art of War: “Fight, but know where there are sufficiencies and deficiencies.” Our study does give an answer to the limited question of the effect of short-term treatment on mod...

Lepton number charges might be the source of long range forces. If one accepts that neutrinos produced in the Sun do indeed oscillate while crossing the interior of the Sun, then the shift in the phase of the neutrino wavefunction caused by an hypothetical potential associated to the leptonic charge of the electrons in the Sun could affect the oscillation pattern beyond what is actually observe...

abstract sun was always in special place among iran and world myths that can be know as the eldest station for worshiping sun, cross or swastika is the most common face which has been turned to capital for the craftsmen and artists of the various eras in order to decorate handicrafts beside other various images of sun.  this   epidiascope is one of the eldest ancient epidiascope and it can be s...

solar mini-dimmings can be detect in the extreme ultra-violet coronal eruptions. here, sequences of 171_a images taken by solar dynamic observatory/atmospheric imaging assembaly on 13 june 2010 are used. in this special day, both of coronal mass ejection and prominence were observed. the average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
