    Density-orbital embedding theory

    In the article density-orbital embedding (DOE) theory is proposed. DOE is based on the concept of density orbital (DO), which is a generalization of the square root of the density for real functions and fractional electron numbers. The basic feature of DOE is the representation of the total supermolecular density ρs as the square of the sum of the DO Ο†a, which represents the active subsystem A and the square root of the frozen density ρf of the environment F. The correct ρs is obtained with Ο†a being negative in the regions in which ρf might exceed ρs. This makes it possible to obtain the correct ρs with a broad range of the input frozen densities ρf so that DOE resolves the problem of the frozen-density admissibility of the current frozen-density embedding theory. The DOE Euler equation for the DO Ο†a is derived with the characteristic embedding potential representing the effect of the environment. The DO square Ο†a2 is determined from the orbitals of the effective Kohn-Sham (KS) system. Self-consistent solution of the corresponding one-electron KS equations yields not only Ο†a2, but also the DO Ο†a itself. Β© 2010 The American Physical Society

    The 1,3-dicarbonyl derivatives of 2-methyl-1,4-dihydroquinoline-4-one have been synthesized by alkylation of methylene active compounds with 3-dimethylaminomethyl-2-methyl-1,4-dihydroquinoline-4-one. These compounds are the convenient starting material for creating the new chemical libraries in the series of 3-heteryl substituted 2-methyl-1,4-dihydroquinoline-4-ones. In this work the examples of the synthesis of new quinolone-pyrazolone systems are presented. Their condensation with hydrazine hydrate resulted in the new derivatives of 2-methyl-3-[(5-oxo-4,5-dihydro-1H-pyrazol-4-yl)methyl]-1,4-dihydroquinolin-4-ones. The estimation of novelty of the compounds obtained in such chemical databases as PubChem, ChemBl, Spresi has shown that these substances are not present in these sources, and the chemical scaffold – quinolone bound via the methylene bridge with azoles is new. Determination of 2D similarity of the compounds synthesized by standard molecular descriptors with the biologically active structures in the ChemBl_20 database has shown the uniqueness of a new quinolone scaffold and the potential anti-inflammatory activity for compounds of this series. The molecular similarity has been determined using the ChemAxon software (JKlustor, Instant JChem).АлкилированиСм 3-Π΄ΠΈΠΌΠ΅Ρ‚ΠΈΠ»Π°ΠΌΠΈΠ½ΠΎΠΌΠ΅Ρ‚ΠΈΠ»-2-ΠΌΠ΅Ρ‚ΠΈΠ»-1,4-Π΄ΠΈΠ³ΠΈΠ΄Ρ€ΠΎΡ…ΠΈΠ½ΠΎΠ»ΠΈΠ½-4-ΠΎΠ½ΠΎΠΌ ΠΌΠ΅Ρ‚ΠΈΠ»Π΅Π½Π°ΠΊΡ‚ΠΈΠ²Π½Ρ‹Ρ… соСди- Π½Π΅Π½ΠΈΠΉ Π±Ρ‹Π»ΠΈ синтСзированы 1,3-Π΄ΠΈΠΊΠ°Ρ€Π±ΠΎΠ½ΠΈΠ»ΡŒΠ½Ρ‹Π΅ ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½Ρ‹Π΅ 2-ΠΌΠ΅Ρ‚ΠΈΠ»-1,4-Π΄ΠΈΠ³ΠΈΠ΄Ρ€ΠΎΡ…ΠΈΠ½ΠΎΠ»ΠΈΠ½-4-ΠΎΠ½Π°.

    4-Hydroxy-/4-oxo tautomerism in the series of 3-substituted 2-methyl-quinolin-4(1H)-ones has been studied by 13C NMR-spectroscopy and quantum-chemical methods in various approximations (restricted Hartree-Fock method, DFT and MP2) for the isolated molecules and for solutions using empirical correction of effects for solvents (PCM COSMO procedure). Substituents that are different in their nature have no significant influence on the value of the chemical shift of carbon in position C4 of the quinolone cycle. The only exception is the carbon shielding associated with the bromine atom in the molecule of 3-bromo-2-methyl-1,4-dihydroquinoline-4-one. Significant deshielding detected in all cases in 13C NMR-spectra of the carbon nuclei in position 4 of the ring is in favour of the existence of all derivatives studied as 4-oxo forms in DMSO-d6 solution. The experimental and calculated values for the chemical shift of carbon in position C4 of 4-oxo and 4-hydroxy isomers differ considerably and can be used as a criterion for assigning quinolin-4 (1H)-ones to a particular tautomeric form.Π‘ ΠΏΠΎΠΌΠΎΡ‰ΡŒΡŽ ЯМР 13Π‘ спСктроскопии ΠΈ ΠΊΠ²Π°Π½Ρ‚ΠΎΠ²ΠΎ-химичСскими ΠΌΠ΅Ρ‚ΠΎΠ΄Π°ΠΌΠΈ Π² Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… приблиТСниях (ΠΎΠ³Ρ€Π°Π½ΠΈΡ‡Π΅Π½Π½Ρ‹ΠΉ ΠΌΠ΅Ρ‚ΠΎΠ΄ Π₯Π°Ρ€Ρ‚Ρ€ΠΈ-Π€ΠΎΠΊΠ°, DFT ΠΈ МР2) для ΠΈΠ·ΠΎΠ»ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹Ρ… ΠΌΠΎΠ»Π΅ΠΊΡƒΠ» ΠΈ растворов с использованиСм эмпиричСской ΠΊΠΎΡ€Ρ€Π΅ΠΊΡ†ΠΈΠΈ эффСктов растворитСлСй (ΠΏΡ€ΠΎΡ†Π΅Π΄ΡƒΡ€Π° РБМ COSMO) исслСдована 4-гидрокси 4-оксо-таутомСрия Π² ряду ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½Ρ‹Ρ… 3-Π·Π°ΠΌΠ΅Ρ‰Π΅Π½Π½Ρ‹Ρ… 2-ΠΌΠ΅Ρ‚ΠΈΠ»Ρ…ΠΈΠ½ΠΎΠ»ΠΈΠ½-4(1Н)-ΠΎΠ½ΠΎΠ².

    The article deals with the actual issue of mortgage lending in Ukraine. The housing issue is an acute issue nowadays and there are many risky points when signing a bank agreement. There is no consensus among scientists on the definition and classification of a mortgage. The comparative characteristics of the types of loan repayments make it possible to determine the optimal first payment option and the subsequent payment system.Efinition of the concept of mortgage its structure and comparison with respect to different banking structures.The problem of housing construction, mechanisms and instruments of its financing in Ukraine is actively discussed. This is particularly true of the crisis conditions under which the country is now developing. The work of leading domestic and foreign economists and financiers is devoted to the study of the problem of mortgage lending. The theoretical basis of this study was the works of Ukrainian scientists, such as: Timofeev VV, Lagutin VD, Busel VT, Vladichin VV, Yurkevich OM. Construction is one of the most promising industries that can turn people and businesses into high-yield investment resources. Thus, due to the development of the construction industry, several problems of modern Ukraine can be solved - social (providing housing for the population), financial (attracting the necessary investment resources to the country's economy), production (development of related industries such as construction materials production and others).Π‘Ρ‚Π°Ρ‚Ρ‚ΡŽ присвячСно Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΠΌΡƒ ΠΏΠΈΡ‚Π°Π½Π½ΡŽ Ρ–ΠΏΠΎΡ‚Π΅Ρ‡Π½ΠΎΠ³ΠΎ крСдитування Π² Π£ΠΊΡ€Π°Ρ—Π½Ρ–.

    Reflection groups in hyperbolic spaces and the denominator formula for Lorentzian Kac--Moody Lie algebras

    Full text link
    This is a continuation of our "Lecture on Kac--Moody Lie algebras of the arithmetic type" \cite{25}. We consider hyperbolic (i.e. signature (n,1)(n,1)) integral symmetric bilinear form S:MΓ—Mβ†’ZS:M\times M \to {\Bbb Z} (i.e. hyperbolic lattice), reflection group WβŠ‚W(S)W\subset W(S), fundamental polyhedron \Cal M of WW and an acceptable (corresponding to twisting coefficients) set P({\Cal M})\subset M of vectors orthogonal to faces of \Cal M (simple roots). One can construct the corresponding Lorentzian Kac--Moody Lie algebra {\goth g}={\goth g}^{\prime\prime}(A(S,W,P({\Cal M}))) which is graded by MM. We show that \goth g has good behavior of imaginary roots, its denominator formula is defined in a natural domain and has good automorphic properties if and only if \goth g has so called {\it restricted arithmetic type}. We show that every finitely generated (i.e. P({\Cal M}) is finite) algebra {\goth g}^{\prime\prime}(A(S,W_1,P({\Cal M}_1))) may be embedded to {\goth g}^{\prime\prime}(A(S,W,P({\Cal M}))) of the restricted arithmetic type. Thus, Lorentzian Kac--Moody Lie algebras of the restricted arithmetic type is a natural class to study. Lorentzian Kac--Moody Lie algebras of the restricted arithmetic type have the best automorphic properties for the denominator function if they have {\it a lattice Weyl vector ρ\rho}. Lorentzian Kac--Moody Lie algebras of the restricted arithmetic type with generalized lattice Weyl vector ρ\rho are called {\it elliptic}Comment: Some corrections in Sects. 2.1, 2.2 were done.

    Adiabatic response time-dependent density functional theory (TDDFT) suffers from the restriction to basically an occupied β†’ virtual single excitation formulation. Adiabatic time-dependent density matrix functional theory allows to break away from this restriction. Problematic excitations for TDDFT, viz. bonding-antibonding, double, charge transfer, and higher excitations, are calculated along the bond-dissociation coordinate of the prototype molecules
