XML-relational systems with well defined XML and relational schemas are widely used in industry. In the presence of rapidly changing requirements both schemas of such a model need continuous evolution, which can be performed by a formal framework that describes the evolution of the mutually dependent schema pairs of the system as sequences of elementary schema transformations. There are a numbe...

It is well known that x-translation and t-translation invariance of (1) leads to the following symmetries: ux, ut of the KdV equation (1). In order to find more generalized symmetries, the concepts of recursion operators or strong symmetries, and hereditary symmetries were introduced by Olver and Fuchssteiner and used to find these symmetries [1, 2]. Furthermore, Galilean invariance of the KdV ...

The present Article revisits the refugee definition and non-refoulement principle in context of some western states’ pushback policies under international law. Recent incidents have shown that states pushed back refugees by employing a nativist approach for political ends. In addition, mentioned many situations made references to produced false narratives about justify their illicit actions. By...

Fermionic Gaussian Projected Entangled Pair States are fermionic tensor network state constructions which describe the physics of ground states non-interacting Hamiltonians. As states, one may study and analyze them very efficiently, in both analytical numerical means. Recently it was shown that they be used as starting point - after applying so-called PEPS gauging mechanisms for variational la...

leiomyoma of the esophagus is rare, but it is the commonest among the benigh tumors of the esophagus. among 95 cases of esophageal tumors, there was just 4 cases of leiomyoma (3 were females and 1 was male) and this is contrary to the reports already published. main symptoms of esophageal leiomyoma include: disphagia, pain and hematemesis from the above mentioned cases 1 tumor was in the thorac...


 In today's world, religion is increasingly demanded to play an active role in various human problems. This approach not used research settings but rather as a science-based perspective or paradigm for understanding religion. To clearly understand aspects of Islamic teachings, approaches are needed from scientific fields. Apart that, it turns out that agricultural science required discuss...

This study was carried out using Moderate Resolution Imaging Spectroradiometer (MODIS) 1 km × resolution records on board Terra and Aqua satellites in-situ measurements during the period (2003–2019). In spite of presence increasing atmospheric warming, in summer when evaporation is maximal, fresh-water Lake Kinneret, satellite data revealed absence surface water temperature (SWT) trends. The SW...
