description: Di, tri, tetra and pentacyclophosphazenes substituted on the phosphorus atoms by CH3, F, Cl and Br atoms corresponding to (X2PN)n structures have been studied theoretically at the B3LYP/6-311++G(d,p) level. After a brief discussion of their geometries comparing them to those of the conjugated carbocycles, (CH)n, of the same size, the absolute shieldings calculated with the GIAO and ZORA approximations will be reported. For the Cl and mainly for the Br substituted cyclo[n]-phosphazenes, relativistic corrections are absolutely necessary for 31P and useful for 15N chemical shifts.
title: MULTILEVEL MODELS OF INELASTIC DEFORMATION: DETERMINATION OF STABLE LOW ANGLE BOUNDARIES
Creators: name: Kondratev, N.S.
name: Trusov, P.V.
Publisher: name: Peter the Great St. Petersburg Polytechnic University
Year: 2019

description: The paper considers the method for determining stable low angle cell boundaries.
The multilevel physical approach is applied to model inelastic deformation, using which
shears are found for slip systems of the crystal. Based on these data, the density of two types
of dislocation defects, which are stopped during deformation at crystallite boundaries, is
introduced into consideration. The optimization problem is posed for finding sections of the
boundary with reduced energy. The dependence of orientation of these sections relative to the
crystallographic coordinate system is investigated. The results of solving the optimization
problem and their analysis are presented.
Topology trivialization and large deviations for the minimum in the simplest random optimization

description: Finding the global minimum of a cost function given by the sum of a quadratic and a linear form in N real variables over (N-1)- dimensional sphere is one of the simplest, yet paradigmatic problems in Optimization Theory known as the "trust region subproblem" or "constraint least square problem". When both terms in the cost function are random this amounts to studying the ground state energy of the simplest spherical spin glass in a random magnetic field. We first identify and study two distinct large-N scaling regimes in which the linear term (magnetic field) leads to a gradual topology trivialization, i.e. reduction in the total number N_{tot} of critical (stationary) points in the cost function landscape. In the first regime N_{tot} remains of the order $N$ and the cost function (energy) has generically two almost degenerate minima with the Tracy-Widom (TW) statistics. In the second regime the number of critical points is of the order of unity with a finite probability for a single minimum. In that case the mean total number of extrema (minima and maxima) of the cost function is given by the Laplace transform of the TW density, and the distribution of the global minimum energy is expected to take a universal scaling form generalizing the TW law. Though the full form of that distribution is not yet known to us, one of its far tails can be inferred from the large deviation theory for the global minimum. In the rest of the paper we show how to use the replica method to obtain the probability density of the minimum energy in the large-deviation approximation by finding both the rate function and the leading pre-exponential factor.

description: This paper is focused on the study of the effect of high heating rates on austenite
formation of 18NiCrMo5 steel. The prior martensitic microstructure was characterized with
scanning electron microscopy and Vicker micro-hardness. Then dilatometric tests were
performed at 12 different heating rates (in the range of 100 - 3000°C/s), to evaluate the
critical points and the key factor governing the austenite formation with high heating rates.
After these tests, the microstructures obtained were analyzed by optical microscopy, scanning
and transmission electron microscopy. The Ac1 and Ac3 temperatures initially increased with
heating rate, reaching a maximum and then decrased. The formation of austenite from
martensite, with low heating rates, was diffusive, whereas with high heating rates, it took
place through a displacive mechanism. Moreover, a higher dislocation density characterized
the austenite obtained with high heating rates.

description: We calculate the present expansion of our Universe endowed with relict colored objects - quarks and gluons - that survived hadronization either as isolated islands of quark-gluon "nuggets", or spread uniformly in the Universe. In the first scenario, the QNs can play the role of dark matter. In the second scenario, we demonstrate that uniform colored objects can play the role of dark energy providing the late-time accelerating expansion of the Universe.

description: In this paper, we discuss optimality conditions for optimization problems subject to random state constraints, which are modeled in probabilistic or almost sure form. While the latter can be understood as the limiting case of the former, the derivation of optimality conditions requires substantially different approaches. We apply them to a linear elliptic partial differential equation (PDE) with random inputs. In the probabilistic case, we rely on the spherical-radial decomposition of Gaussian random vectors in order to formulate fully explicit optimality conditions involving a spherical integral. In the almost sure case, we derive optimality conditions and compare them to a model based on robust constraints with respect to the (compact) support of the given distribution.

description: The effects of deformation and heat treatment on the electrical resistivity and the
tensile strength of nanostructured Cu/Cu-18%Nb composite wires are studied. The correlated
behavior of electrical resistivity and strength depending on the mode of thermo-mechanical
processing is ascertained. The main mechanism of strengthening and increasing the electrical
conductivity, associated with the reduction in the size of the structure, is considered. A good
agreement is shown between the average distances between the Nb filament measured by
SEM and extracted using the inversion of the resistivity size effect model. On the other hand,
direct calculations of the strength value in accordance with the most common modern models
are not consistent with experiments. In conclusion, the reasons for this discrepancy are
discussed.

description: In this study, five new paraben substituted cyclotriphosphazene compounds containing hydrophilic glycol groups were successfully synthesized. All synthesized cyclotriphosphazene compounds 1-10 were fully characterized via general spectroscopic techniques such as 1H, 31P NMR and MALDI-TOF mass spectrometry. In addition, the investigations of the UV-vis absorption and fluorescence emission properties of the 1-10 carried out via absorption and fluorescence spectroscopies in different solvents. The absorbance bands of the all synthesized compounds 1-10 were observed at about 230–300 nm in all solvents studied. Furthermore, the highest fluorescence emission intensity of the compounds 1-10 was observed in tetrahydrofuran at about 312 nm and the lowest emission intensity was observed in chloroform. The synthesized molecules can be used as custom designed molecules to investigate the DNA binding properties in automatic biosensor device in our laboratories, since they carry hydrophilic glycol units for water solubility and paraben derivatives for DNA effecting properties.

description: We investigate the holographic fermions over a gravitational lattice background with a rather low temperature. Since the rotation symmetry is broken on the plane, the lattice effects change the shape of the Fermi surface within the first Brillouin zone from a circle to an ellipse. When the Fermi surface intersects with the Brillouin zone boundary, the band structure with a band gap is observed through a numerical analysis. We construct a lattice model sourced by a scalar field as well as an ionic lattice model without the scalar field. In both cases we find the similar physical results.

description: In order to identify the successive stages of developing the hierarchy of multiscale
mechanisms of dynamic straining, the shock-induced mesostructure formation is studied in
combined experiments. Shock tests of two kinds of aluminum alloy, 1561 and 1565 alloys
were conducted in parallel in two regimes of loading: (i) under uniaxial strain conditions and
(ii) in high velocity penetration. Combination of loading regimes allows the correlation in
formation of multiscale structure depending on strain rate and scheme of shock loading to be
traced for both alloys. Formation of mesoscale-1 (1-10 µm) is initiated by the particle velocity
pulsations resulted from space polarization of dislocation structure.
In 1561 aluminum alloy the structural elements of mesoscale-2 (50-150 µm) are the result of
grouping the microshears, whereas in 1565 alloy the mesostructure is the fault formations
localized near the boundary of penetration cavern. The strength behavior of both kinds of
aluminum alloy proves to be opposite - when resistance to penetration increases, the spall
strength decreases.

Several molecules have demonstrated a considerable cytotoxicity against A549, HEK293T, MCF7 and VA13 cancer cell lines. The possible mechanism of anticancer activity of the synthesized compounds based on literature data may be the inhibition of p53/MDM2 interaction; however, we did not observe significant p53 activation using a reporter construction in A549 cell line in the relevant concentration range.

description: Double ring formation on Co2MnSi (CMS) films is observed at electrical breakdown voltage during local anodic oxidation (LAO) using atomic force microscope (AFM). Corona effect and segregation of cobalt in the vicinity of the rings is studied using magnetic force microscopy and energy dispersive spectroscopy. Double ring forma-tion is attributed to the interaction of ablated material with the induced magnetic field during LAO. Steepness of forward bias transport characteristics from the unperturbed region of the CMS film suggest a non equilibrium spin contribution. Such mesoscopic textures in magnetic films by AFM tip can be potentially used for memory storage applications.

description: We investigate theoretically a dilute stream of free quantum particles passing through a macroscopic circular aperture of matter-waves and then moving in a space at a finite temperature, taking into account the dissipative coupling with the environment. The portion of particles captured by the detection screen is studied by varying the distance between the aperture and the screen. Depending on the wavelength, the temperature, and the dimension of the aperture, an unusual local valley-peak structure is found in increasing the distance, in contrast to traditional thinking that it decreases monotonically. The underlying mechanism is the nonlocality in the process of decoherence for an individual particle.

description: We previously designed and prepared the first molecules to exhibit observable CD spectra by n-σ* excitation, 2,6-dithiaspiro[3.3]heptane 2,6-dioxide. Spiro[3.3]heptane frameworks possess axial asymmetry due to puckering of 2 four-membered rings; the ring bonds are rich in p-character due to acute bond angles, which lowers the σ* energy levels. In contrast, the lone pairs are rich in s-character, which results in a good donor with conformational fixation. We expected that, instead of lone pairs as donating orbitals, the use of σ-electron-donating Si-Si bonds should result in UV absorption in the observable range (>180 nm), so that the Cotton effect could appear, at least partially, in that range. We designed 2,6-disilyl-2,6-disilaspiro[3.3]heptanes as models, and performed theoretical calculations to confirm our idea.
Deformation of Matrix Geometry via Landau Level Evolution

description: We propose a scheme for the construction of deformed matrix geometries using Landau models. The Landau models are practically useful tools to extract matrix geometries. The level projection method however cannot be applied straightforwardly to the Landau models on deformed manifolds, as they do not generally exhibit degenerate energy levels. We overcome this problem by exploiting the idea of spectral flow. Taking a symmetric matrix geometry as a reference point of the spectral flow, we evolve the matrix geometry by deforming the Landau model. In this process, unitarity is automatically preserved. The explicit matrix realization of the coordinates is derived mechanically even for a non-perturbative deformation. We clarify basic properties of the deformed matrix geometries through a concrete analysis of the non-relativistic and relativistic Landau models on expanding two-sphere and elongating ellipsoid. The obtained ellipsoidal matrix geometries show behaviors quantitatively different in each Landau level, but qualitatively similar to their classical counterpart. We also numerically investigate the differences between the ellipsoidal matrix geometry and the fuzzy ellipsoid.

From the docking results, it was determined that the compounds (Z)-dimethyl 5-(3-nitrobenzylidene)−2,4-dioxothiazolidin-3-ylphosphonate (7a), (Z)-dimethyl 5-(3-chloro-4-fluorobenzylidene)−2,4-dioxothiazolidin-3-ylphosphonate (7f), (Z)-dimethyl 5-(2,4-dichlorobenzylidene)−2,4-dioxothiazolidin-3-ylphosphonate (7e) and (Z)-dimethyl 5-((5-methoxypyridin-2-yl)methylene)−2,4-dioxothiazolidin-3-ylphosphonate (7j) have shown better binding energies (−7.8, −7.6, −7.5 and −7.6 Kcal/mol) with the target gene, PPAR γ than the reference drug, Rosiglitazone (−7.4 Kcal/mol). In vitro anti-diabetic activity of the title compounds was also screened by standard α-amylase inhibition assay. Some of the tested compounds proved to possess promising activity when compared with the reference drug.

description: Complex networks provide a suitable framework to characterize air traffic. Previous works described the world air transport network as a graph where direct flights are edges and commercial airports are vertices. In this work, we focus instead on the properties of flight delays in the US air transportation network. We analyze flight performance data in 2010 and study the topological structure of the network as well as the aircraft rotation. The properties of flight delays, including the distribution of total delays, the dependence on the day of the week and the hour-by-hour evolution within each day, are characterized paying special attention to flights accumulating delays longer than 12 hours. We find that the distributions are robust to changes in takeoff or landing operations, different moments of the year or even different airports in the contiguous states. However, airports in remote areas (Hawaii, Alaska, Puerto Rico) can show peculiar distributions biased toward long delays. Additionally, we show that long delayed flights have an important dependence on the destination airport.

description: Постановка проблемы. Линейные ТЕМ-рупоры из тонких проводников удобны для применения на частотах f < 2000 МГц, так как имеют существенные преимущества по массе и парусности перед рупорами из сплошных металлических пластин.
Цель. Описать результаты численного моделирования проволочных ТЕМ-рупоров, в которых форма проводников описывается экспоненциальной функцией, и рассмотреть антенные решетки из таких рупоров, их диапазонные свойства и возможности по фазовому сканированию.
Результаты. Приведены результаты численного моделирования линейной и плоской антенных решеток излучателей в виде проволочных ТЕМ-рупоров. Рассмотрены диапазонные свойства отдельного излучателя и параметры линейной и плоской решеток. Показано, что линейная решетка без сканирования имеет коэффициент перекрытия по частоте, равный 10, по критерию согласования излучателей в составе решетки и по критерию сохранения формы диаграммы направленности.
Практическая значимость. Установлено, что в плоской решетке коэффициент перекрытия по частоте меньше, чем в линейной решетке, и уменьшается с ростом числа строк.

description: We conjecture the existence of a relationship between frustration and the transition point at zero temperature of Ising spin glasses. The relation reveals that, in several Ising spin glass models, the concentration of ferromagnetic bonds is close to the critical concentration at zero temperature when the output of a function about frustration is equal to unity. The function is the derivative of the average number of frustrated plaquettes with respect to the average number of antiferromagnetic bonds. This relation is conjectured in Ising spin glasses with binary couplings on two-dimensional lattices, hierarchical lattices, and three-body Ising spin glasses with binary couplings on two-dimensional lattices. In addition, the same argument in the Sherrington-Kirkpatrick model yields a point that is identical to the replica-symmetric solution of the transition point at zero temperature.

description: This paper provides a further step in our program of studying superconformal nets over S^1 from the point of view of noncommutative geometry. For any such net A and any family Delta of localized endomorphisms of the even part A^gamma of A, we define the locally convex differentiable algebra A_Delta with respect to a natural Dirac operator coming from supersymmetry. Having determined its structure and properties, we study the family of spectral triples and JLO entire cyclic cocycles associated to elements in Delta and show that they are nontrivial and that the cohomology classes of the cocycles corresponding to inequivalent endomorphisms can be separated through their even or odd index pairing with K-theory in various cases. We illustrate some of those cases in detail with superconformal nets associated to well-known CFT models, namely super-current algebra nets and super-Virasoro nets. All in all, the result allows us to encode parts of the representation theory of the net in terms of noncommutative geometry.

description: We previously designed and prepared the first molecules to exhibit observable CD spectra by n-σ* excitation, 2,6-dithiaspiro[3.3]heptane 2,6-dioxide. Spiro[3.3]heptane frameworks possess axial asymmetry due to puckering of 2 four-membered rings; the ring bonds are rich in p-character due to acute bond angles, which lowers the σ* energy levels. In contrast, the lone pairs are rich in s-character, which results in a good donor with conformational fixation. We expected that, instead of lone pairs as donating orbitals, the use of σ-electron-donating Si-Si bonds should result in UV absorption in the observable range (>180 nm), so that the Cotton effect could appear, at least partially, in that range. We designed 2,6-disilyl-2,6-disilaspiro[3.3]heptanes as models, and performed theoretical calculations to confirm our idea.

description: Molecular anthracene has been used as an arene in the Friedel-Crafts (FC) type arylation reaction of anthracenyl-α-hydroxyphosphonate in the presence of acid. A diverse product formation is observed, in which anthracene unit is found to be linked through its C1 position with α-C of phosphonate. Interestingly, the molecular conformation (X-ray structure) of this phosphonate reveals one of the bond angles of a tetrahedral carbon as 118° which is close to the C of sp2 character. Further, molecular anthracene is also recognized to attack at the C10 position of 9-anthracenylphosphonate through C1 or C2 or C9 atoms and the structures of three isomeric phosphonates are established with the help of 1H and 31P NMR studies. The bis-anthracenyl compounds with a P-CH2 unit have been successfully utilized in Horner-Wadsworth-Emmons (HWE) reactions to afford extensive bis-anthracenyl-linked π-conjugates.
