Purpose is the development of mathematical models to evaluate deformation parameters rock mass-well geological and engineering system within anisotropic media. Methods. Both neural modeling a stress state under conditions uncertainty has been applied for studies. From viewpoint modeling, analysis probability factors, complicating drilling, should involve number assumptions strength characterist...

A mathematical model of average nonuniform flow in heterogeneous tratified media is developed. The averaged Darcy's law is obtained by deriving the analytical expression of the effective conductivity tensor for media with small heterogeneities. The fundamental solution of the average flow equation (mean Green function) corresponding to the flow toward a single point source of deterministic disc...

The soil around a drain well is traditionally divided into smeared zone and undisturbed zone with constant hydraulic conductivity. In reality, hydraulic conductivity of the soil changes continuously and it may not be always appropriate to approximate its distribution with two zones. In this study, the horizontal hydraulic conductivity of the soil is described by an arbitrary function of radial ...

Regulation of biological processes through the use of genetic elements is a central part of biological research and also holds great promise for future therapeutic applications. Oligonucleotides comprise a class of versatile biomolecules capable of modulating gene regulation. Gene therapy, the concept of introducing genetic elements in order to treat disease, presents a promising therapeutic st...

BACKGROUND Very few cases of severe penetrating injuries to the skull base with a seemingly innocuous object have been described in the literature. Of the cases reported, only ten involve a penetrating screwdriver. However, the choice of therapeutic management, whether it be emergency surgical or non-surgical removal of the penetrating object as well as the selected surgical approach remain qui...

We study the Josephson current (supercurrent) in a system consisting of two superconductors connected to single-level quantum dot (QD), which is also side-coupled nanowire hosting Majorana bound states (MBSs). Our results show that MBSs change both peak height and position current-carrying density (CCDOS), this determines amplitude due phase difference between superconductors. By adjusting ener...
