Suppression of Superconductivity in Disordered Films: Interplay of Two-Dimensional Diffusion and Three-Dimensional Ballistics

JETP Letters - Suppression of the critical temperature in homogeneously disordered superconducting films is a consequence of the disorder-induced enhancement of Coulomb repulsion. We demonstrate...     

Synthesis of a new betulinic acid glycoconjugate with N-acetyl-d-galactosamine for the targeted delivery to hepatocellular carcinoma cells

Russian Chemical Bulletin - A new promising conjugate of betulinic acid with N-acetyl-d-galactosamine was synthesized by the simple reaction sequence: esterification and copper-catalyzed...     

Lyapunov Exponent for Whitney’s Problem with Random Drive

JETP Letters - We consider the statistical properties of a non-falling trajectory in the Whitney problem of an inverted pendulum excited by an external force. In the case where the external force...     

Interaction between Wells and a Groundwater Stream

The interaction between a natural contaminated groundwater stream and a flow induced by wells is investigated. When the flow is potential, the boundaries of the regions protected from the contaminated stream are determined for several configurations of their location and all possible flow diagrams. Dimensionless critical well flow rates corresponding to transition from one diagram to another are found.     

Temperature Shift of the Zero-Phonon f–f Lines of Er3+ Luminescence in Quantum Paraelectric KTaO3

Physics of the Solid State - In KTaO3:Er crystals, we observed a temperature shift, unusual for rare earth impurities, for narrow zero-phonon luminescence lines, due to the 4S3/2 → 4I13/2,...     

Plane problem of filtration consolidation for an elastic half-space with discontinuous initial conditions

The plane consolidation problem for an elastic half-space under an instantaneously applied vertical load is solved in the general case assuming that the Terzaghi hypothesis holds.     

Bisborohydride yttrium complexes containing amidinate ligands [o-Me2NC6H4CH2C(NR)2]Y(BH4)2L n (R = Pri,L = DME,n = 1; R = Cy,L = THF,n = 2). Synthesis,structure, and catalytic activity in polymerization of rac-lactide and isoprene

Russian Chemical Bulletin - A reaction of o-N,N-dimethyltoluidine lithium derivative (o-Me2NC6H4CH2Li) with carbodiimides (RN=C=NR, where R = Pri, Cy) in THF at room temperature leads to lithium...     

Integration of Banach-valued functions and Haar series with Banach-valued coefficients

It is proved that for any Banach space each everywhere convergent Haar series with coefficients from this space is the Fourier–Haar series in the sense of Henstock type integral with respect to a dyadic differential basis. At the same time, the almost everywhere convergence of a Fourier–Henstock–Haar series of a Banach-space-valued function essentially depends on properties of the space.     

Henstock type integral in compact zero-dimensional metric space and quasi-measures representations

Properties of a Henstock type integral defined on a compact zero-dimensional metric space are studied. Theorems on integral representation of so-called quasi-measures, i.e., linear functionals on the space of ??polynomials?? defined on the space of the above mentioned type, are obtained.
