Lanthanum Activity in La–U–Ga–X Systems (X = Al or In)
Lanthanum activity was determined for the first time in La–U–Ga–X (X = Al or In) alloys. Ga–In and Ga–Al alloys were taken in the eutectic composition (21.8 wt.% In and 1.6 wt.% Al, respectively). Measurements were performed between 573 and 1073 K employing the e.m.f. method.

Способ формирования профессиональной зрелости управленца
Робота присвячена проблемі досягнення управлінської зрілості як результату особистісного та професійного розвитку. Розглянуто кілька підходів до рольового представлення управлінської діяльності, які можуть бути інтегровані за допомогою використання Я-концепції. Професійний розвиток пропонується трактувати як розширення репертуару управлінських ролей за рахунок поєднання навчання та практики, яке гарно описується циклом емпіричного навчання Колба. Професійний розвиток передбачає свідоме формулювання бажаних управлінських ролей та їх послідовне засвоєння через розвиток Я-концепції. Управлінська зрілість при такому підході стає змінною величиною, яка обумовлена репертуаром свідомо обраних і засвоєних управлінських ролей. У роботі наведено приклад можливої структури рольового репертуару та визначено напрямок

The professional development, in turn, considered as an extension of the repertoire of managerial roles being able to accomplish by a manager. This kind of development involves a combination of training and practice, which described by Kolb empirical learning cycle. The formulation of current and desirable managerial roles provided using
well-known psychological self-concept. Professional development in thus approach looks like a deliberate formulation of desired managerial roles and their sequential assimilation through the development of self-concept. As an example of composition of roles considered roles of manager, leader, job architect and strategic architect. Each role requires a certain competence (ability) due to activities in the roles — cognitive, intrapersonal or interpersonal ones.
When using role-based approach managerial maturity means ability to play a new role or new level of mastering in the role. An important factor of managerial maturity is conscious «design» the self-concept by manager, including models of «real self» and an «ideal self» meaning existing and desired role repertoire.Работа посвящена проблеме достижения управленческой зрелости как результата личностного и профессионального развития.

On the 75th anniversary of the establishment of Ophthalmic Pathomorphology Laboratory at the Filatov Institute of Eye Disease and Tissue Therapy
The article focuses on the results of diagnostic studies and research performed in the Ophthalmic Pathomorphology Laboratory over the 75 years of its existence. More than 250,000 histological studies of surgical clinical material and biopsy material from more than 100,000 patients have been performed over the whole period of existence of the laboratory since 1946. In addition, about 1000 science works including 26 monographs have been published, and dozens of ophthalmologists were provided special assistance in performing morphological studies for their doctoral dissertations and candidate of science theses
Weakly-nonlocal Symplectic Structures, Whitham method, and weakly-nonlocal Symplectic Structures of Hydrodynamic Type
We consider the special type of the field-theoretical Symplectic structures
called weakly nonlocal. The structures of this type are in particular very
common for the integrable systems like KdV or NLS. We introduce here the
special class of the weakly nonlocal Symplectic structures which we call the
weakly nonlocal Symplectic structures of Hydrodynamic Type. We investigate then
the connection of such structures with the Whitham averaging method and propose
the procedure of "averaging" of the weakly nonlocal Symplectic structures. The
averaging procedure gives the weakly nonlocal Symplectic Structure of
Hydrodynamic Type for the corresponding Whitham system. The procedure gives
also the "action variables" corresponding to the wave numbers of -phase
solutions of initial system which give the additional conservation laws for the
Whitham system.Comment: 64 pages, Late
Calculation of the moscovium ground-state energy by quantum algorithms
We investigate the possibility to calculate the ground-state energy of the
atomic systems on a quantum computer. For this purpose we evaluate the lowest
binding energy of the moscovium atom with the use of the iterative phase
estimation and variational quantum eigensolver. The calculations by the
variational quantum eigensolver are performed with a disentangled unitary
coupled cluster ansatz and with various types of hardware-efficient ansatze.
The optimization is performed with the use of the Adam and Quantum Natural
Gradients procedures. The scalability of the ansatze and optimizers is tested
by increasing the size of the basis set and the number of active electrons. The
number of gates required for the iterative phase estimation and variational
quantum eigensolver is also estimated.Comment: 29 pages, 5 figure

Quasiperiodic functions theory and the superlattice potentials for a two-dimensional electron gas
We consider Novikov problem of the classification of level curves of
quasiperiodic functions on the plane and its connection with the conductivity
of two-dimensional electron gas in the presence of both orthogonal magnetic
field and the superlattice potentials of special type. We show that the
modulation techniques used in the recent papers on the 2D heterostructures
permit to obtain the general quasiperiodic potentials for 2D electron gas and
consider the asymptotic limit of conductivity when . Using the
theory of quasiperiodic functions we introduce here the topological
characteristics of such potentials observable in the conductivity. The
corresponding characteristics are the direct analog of the "topological
numbers" introduced previously in the conductivity of normal metals.Comment: Revtex, 16 pages, 12 figure
