Designing interference-aware network selection protocol for WLAN mobile devices
Due to increasing demand of wireless services for portable devices, numerous efforts to enhance wireless network performance have been made for decades. Many researchers were focused on the word ‘seamless’ for sustaining connectivity during a handover process, but wireless performance of destined access point (AP) is rarely considered. This paper analyses thoroughly usual network connection...


Development and validation of a bioanalytical method by LC-MS/MS for the quantification of the LAFIS 10 – an antimalarial candidate – and its pharmacokinetics first evaluation
A rapid and highly sensitive method by LC-MS/MS was developed and validated for the quantification of an antimalarial candidate (LAFIS10) in rat plasma using dexamethasone as internal standard (IS). The chromatographic separation was performed with a Poroshell 120 EC-C18 column. The mobile phase consisted of water (A) and acetonitrile (B), both containing 10 mm of ammonium formate and 0.1% fo...
Viral Carcinogenesis: Factors Inducing DNA Damage and Virus Integration
Viruses are the causative agents of 10%–15% of human cancers worldwide. The most common outcome for virus-induced reprogramming is genomic instability, including accumulation of mutations, aberrations and DNA damage. Although each virus has its own specific mechanism for promoting carcinogenesis, the majority of DNA oncogenic viruses encode oncogenes that transform infected cells, frequently ...


Data Transformation for Confidence Interval Improvement: An Application to the Estimation of Stress-Strength Model Reliability
In many statistical applications, it is often necessary to obtain an interval estimate for an unknown proportion or probability or, more generally, for a parameter whose natural space is the unit interval. The customary approximate two-sided confidence interval for such a parameter, based on some version of the central limit theorem, is known to be unsatisfactory when its true value is close to...
Methods for preparation of transparent conductive diamond-like carbon films and mechanisms of conductivity formation
Technology for obtaining transparent conductive diamond-like carbon films has been developed. Conductivity of the films is ensured by doping with nitrogen during the growth process or by preliminary deposition onto the substrate of a catalyst of nanostructure growth. Optical methods of control of the process which allow varying both the transparency and conductivity of the obtained coatings are...


X-ray Laue diffraction with allowance for two-dimensional curvature of the wavefront: The concept a locally plane wave
Symmetrical Laue diffraction in a perfect crystal with a plane entance surface is considered. The two dimensional curvature of the wave front of the incident beam is taken into account. Using the corresponding Green function, a general expression for the amplitude of diffracted wave in the crystal is presented. Based on this expression, the concept of a locally plane wave is analyzed taking int...
Quantum entanglement and quantum phase transitions in anisotropic two- and three-particle spin-1 Heisenberg clusters
General polynomial case of Heisenberg model for spin-1 two- and three-particle clusters is considered on matter of quantum entanglement and its evolution under quantum phase transitions induced by changes of external parameters. Influence of anisotropy parameter on the phase structure and quantum entanglement is studied. The thermal evolution of quantum entanglement is also studied. Some simila...

Study of the thermally processed lanthanum hexaboride surface
We study the possibility to grow lanthanum oxide (La2O3) on the surface of lanthanum hexaboride (LaB6) with (100)- and (100/110)-orientation in conditions of thermal annealing, in order to produce a metal-oxide-metal structure. Electron microscopic images, X-ray and optical spectra revealed a La2O3 layer of cubic symmetry. The features of the current-voltage and capacitance-voltage characterist...
Vacuum energy-momentum tensor in models with non-trivial topology in the presence of boundaries
The vacuum expectation value of the energy-momentum tensor for a scalar field in models with the compact subspace of an arbitrary geometry in the presence of parallel plates is investigated. The field operator on the plates obeys Robin boundary conditions with constant coefficients. Depending on the values of the coefficients, the vacuum energy density can be either positive or negative. As an ...

Stability of bilayer lipid membrane in the presence of Co-containing metalloporphyrins
Stability of bilayer lipid membrane (BLM) in an electric field in the presence of Co-porphyrin in the solution surrounding BLM is investigated. We have shown that the presence of porphyrin in a solution reduces line tension of the pore edge and surface tension of BLM and increases the number of pores on the BLM. It is also shown that a decrease in the stability of BLM in the electric field in t...
Spin magnetic moment current of impurity electron in a spherical quantum dot
Current of the spin magnetic moment of an electron coupled with hydrogen-like impurity, placed in the center of a spherical quantum dot, is studied. Confinement potential of the quantum dot is approximated by rectangular infinitely high walls. S-states of electron for both positive and negative values of total energy are considered. Dependences of spin magnetic moment current of electron on the...

Crystallization of a flexible-chain polymer in melt in the presence of double-stranded DNA
The behavior of a mixture of short fragments of double-stranded DNA and a flexible-chain polymer is addressed. The role of the DNA double helix in the formation of the crystalline phase in the flexible-chain polymer’s melt is examined. It is shown that the presence of DNA rigid fragments in melt results in increase in the melting temperature. A shift of the melting temperature of a perfect cr...
Modeling of confinement potential for cylindrical quantum dot
Quantum states and energy levels of an electron in a cylindrical quantum dot with different models of confinement potentials are studied. Two models of confinement potentials, Morse potential and modified Pöschl-Teller potential, are considered. It is shown that due to distinction between symmetric and asymmetric nature of potentials, there is a fundamental difference in behavior of the ground...
Investigation of photoelectrical properties of epitaxially grown heterojunction thermophotovoltaic cells
By the method of metal-organic chemical vapor deposition we have epitaxially grown effective samples of InAs/p-GaSb/n-GaSb/n-GaAs/InxGa1−xAs/Ge/Si(113) photovoltaic cells and investigated their photoelectric properties. The suitability of application of quality heterojunction diode structures in termophotovoltaic cells is experimentally proved.
A Nanoplasmonic-Fluorescent Ruler for Detection of Site-Specific Protein Binding to Composite DNA of Multiple Sites
A gold or silver nanoparticles (AuNPs and AgNPs)-supported fluorescent intercalator displacement (FID) assay, termed nanoplasmonic-fluorescent ruler, for site-specific detection of protein binding to composite DNA of multiple sites is constructed. A 20 nm, 100 nm AuNPs, or 80 nm AgNPs is introduced to one end of double-stranded DNA (dsDNA). The dsDNA–AuNPs conjugates are saturated with a DNA ...
