description: Шумовой режим в помещениях во многом определяется внутриквартирными источниками звука. Для его оценки необходимы соответствующие методы расчета шума. Однако в настоящее время отсутствуют исследования возможности его применения для расчета шума в помещениях как в системах акустически связанных помещений. Целью исследования являлись установление возможности использования статистического метода расчета для акустических расчетов в актовом зале. Исследования возможностей статистического метода расчета производились путем сравнения результатов расчетов с предварительный данными. Расчеты выполнялись с использованием разработанной компьютерной программы.
description: The noise regime in the premises is largely determined by the in-house sound sources. Appropriate noise calculation methods are required to evaluate it. However, there are currently no studies on the possibility of its application for calculating noise in rooms as in systems of acoustically coupled rooms. The aim of the study was to establish the possibility of using the statistical calculation method for acoustic calculations in the assembly hall. Studies of the possibilities of the statistical method of calculation were carried out by comparing the calculation results with preliminary data. The calculations were performed using the developed computer program.

description: The objective of this work is to prove, in a first step, the existence and the uniqueness of a solution of the following multivalued deterministic differential equation: $dx(t)+\partial ^-φ(x(t))(dt)\ni dm(t),\ t>0$, $x(0)=x_0$, where $m:\mathbb{R}_+\rightarrow\mathbb{R}^d$ is a continuous function and $\partial^-φ$ is the Fréchet subdifferential of a semiconvex function $φ$; the domain of $φ$ can be non-convex, but some regularities of the boundary are required. The continuity of the map $m\mapsto x:C([0,T];\mathbb{R}^{d})\rightarrow C([0,T] ;\mathbb{R}^{d})$, which associate the input function $m$ with the solution $x$ of the above equation, as well as tightness criteria allow to pass from the above deterministic case to the following stochastic variational inequality driven by a multi-dimensional Brownian motion: $X_t+K_t = ξ+\int_0^t F(s,X_{s})ds + \int_0^t G(s,X_s) dB_s,\; t\geq0$, $\;$ with $dK_{t}(ω)\in\partial^-φ( X_t (ω))(dt)$.

description: целью исследований являлось выявление существующей проблемы при оптимизации движения точки переменной массы (центр масс космического аппарата КА) в гравитационном поле. Она включает в себя выбор, прогнозирование, оптимизацию и расчет траекторий управляемых объектов. Вариационная задача в постановке Лоудена заключается, в определении управлений (величина и направление реактивной силы) и оптимальных траекторий точки, движущейся с ограниченным секундным расходом массы m. Конечный результат вариационной задачи, в определении управлений величина и направление силы тяги, переводящей точку из заданного положения в некоторое конечное, а также минимизирует расход массы. В данной работе аналитические решения вариационной задачи отличаются от решений: спирали Лоудена отличаются законом изменения массы (малая тяга), а следовательно, значениями параметров и характеристиками двигателя. Полученные траектории могут найти применение в задачах ухода и маневрах перехода с орбиты на орбиту
description: the aim of the research was to identify the existing problem in optimizing the movement of a point of variable mass (the center of mass of the spacecraft SC) in a gravitational field. It includes the selection, forecasting, optimization and calculation of trajectories of managed objects. The following are some of their recent results. The variational problem in the formulation of Louden is to determine the controls (magnitude and direction of the reactive force) and the optimal trajectories of a point moving with a limited second mass flow rate m.The end result of the variational problem, in the definition of controls, is the magnitude and direction of the traction force that transfers a point from a given position to a certain final one, and also minimizes the mass consumption. In this work, the analytical solutions of the variational problem differ from the solutions: Lowden spirals differ in the law of mass change (low thrust), and, consequently, in the values of the parameters and characteristics of the engine. The resulting trajectories can find application in problems of escape and maneuvers of transition from orbit to orbit.

description: We present a spectroscopic survey of galaxies in the COSMOS field using the Fiber Multi-Object Spectrograph (FMOS), a near-infrared instrument on the Subaru Telescope. Our survey is specifically designed to detect the Halpha emission line that falls within the H-band (1.6-1.8 um) spectroscopic window from star-forming galaxies with 1.4 < z < 1.7 and M_stellar>~10^10 Msolar. With the high multiplex capability of FMOS, it is now feasible to construct samples of over one thousand galaxies having spectroscopic redshifts at epochs that were previously challenging. The high-resolution mode (R~2600) effectively separates Halpha and [NII]6585 thus enabling studies of the gas-phase metallicity and photoionization state of the interstellar medium. The primary aim of our program is to establish how star formation depends on stellar mass and environment, both recognized as drivers of galaxy evolution at lower redshifts. In addition to the main galaxy sample, our target selection places priority on those detected in the far-infrared by Herschel/PACS to assess the level of obscured star formation and investigate, in detail, outliers from the star formation rate - stellar mass relation. Galaxies with Halpha detections are followed up with FMOS observations at shorter wavelengths using the J-long (1.11-1.35 um) grating to detect Hbeta and [OIII]5008 that provides an assessment of extinction required to measure star formation rates not hampered by dust, and an indication of embedded Active Galactic Nuclei. With 460 redshifts measured from 1153 spectra, we assess the performance of the instrument with respect to achieving our goals, discuss inherent biases in the sample, and detail the emission-line properties. Our higher-level data products, including catalogs and spectra, are available to the community.

Spin-orbital interplay and topology in the nematic phase of iron pnictides

description: The origin of the nematic state is an important puzzle to be solved in iron pnictides. Iron superconductors are multiorbital systems and these orbitals play an important role at low energy. The singular $C_4$ symmetry of $d_{zx}$ and $d_{yz}$ orbitals has a profound influence at the Fermi surface since the $Γ$ pocket has vortex structure in the orbital space and the X/Y electron pockets have $yz$/$zx$ components respectively. We propose a low energy theory for the spin--nematic model derived from a multiorbital Hamiltonian. In the standard spin--nematic scenario the ellipticity of the electron pockets is a necessary condition for nematicity. In the present model nematicity is essentially due to the singular $C_4$ symmetry of $yz$ and $zx$ orbitals. By analyzing the ($π, 0$) spin susceptibility in the nematic phase we find spontaneous generation of orbital splitting extending previous calculations in the magnetic phase. We also find that the ($π, 0$) spin susceptibility has an intrinsic anisotropic momentum dependence due to the non trivial topology of the $Γ$ pocket.

description: The Kuramoto model (KM) of coupled phase oscillators on complete, Paley, and Erdos-Renyi (ER) graphs is analyzed in this work. As quasirandom graphs, the complete, Paley, and ER graphs share many structural properties. For instance, they exhibit the same asymptotics of the edge distributions, homomorphism densities, graph spectra, and have constant graph limits. Nonetheless, we show that the asymptotic behavior of solutions in the KM on these graphs can be qualitatively different. Specifically, we identify twisted states, steady state solutions of the KM on complete and Paley graphs, which are stable for one family of graphs but not for the other. On the other hand, we show that the solutions of the IVPs for the KM on complete and random graphs remain close on finite time intervals, provided they start from close initial conditions and the graphs are sufficiently large. Therefore, the results of this paper elucidate the relation between the network structure and dynamics in coupled nonlinear dynamical systems. Furthermore, we present new results on synchronization and stability of twisted states for the KM on Cayley and random graphs.

In the process of obtaining organo-mineral fertilizers, the conversion of calcium sulfate to ammonium sulfate and the degree of humification of organic substances were studied. It is shown that with an increase in the proportion of phosphogypsum raw materials to manure in composts, the amount of the general form of sulfur oxide increases, but the conversion of sulfur oxide and the degree of humification of organic substances leads to a relative decrease. It was determined that with an increase in the storage time, the manure of phosphorite compost, in it the conversion of sulfur oxide and the degree of humification of organic substances increases.

Ранее нами был предложен способ восстановления «постаревших» силитовых нагревателей путем покрытия их рабочих частей слоем карбида кремния. Однако, исследования рабочих параметров силитовых нагревателей, восстановленных покрытием слоем карбида кремния, по предложенному способу показали, что их рабочий ресурс невелик. Поэтому с целью установления причин низкого ресурса работы были исследованы свойства слоев карбида кремния, полученных на отработавших рабочий ресурс и «постаревших» силитовых нагревателях. Результаты исследований показали, что причиной низкого ресурса работы являются увеличение пористости слоев карбида кремния со временем работы в условиях термоциклирования при высоких температурах, а также окисление и частичная сублимация карбида кремния. Предложен способ и показана возможность восстановления и увеличения рабочего ресурса и рабочей температуры «постаревших» нагревателей путем применения сэндвич слоев карбида кремния и дисилицида молибдена.
description: The resistance of silite (silicon carbide) heaters, providing a temperature of 1400-1450С, will increase over time at high temperatures due to oxidation and partial sublimation of silicon carbide, i.e. they are “getting old”. Earlier, we proposed a method for the restoration of "aged" silite heaters by covering their working parts with a layer of silicon carbide. However, studies of the operating parameters of silite heaters, restored by coating with a layer of silicon carbide, according to the proposed method, showed that their working resource is small. Therefore, in order to establish the reasons for the low working resource, the properties of silicon carbide layers obtained on exhausted working resource and "aged" silite heaters were investigated. The research results showed that the reason for the low working resource an increase in the porosity of silicon carbide layers with the time of operation under thermal cycling conditions at high temperatures, as well as oxidation and partial sublimation of silicon carbide. A method is proposed and the possibility of restoring and increasing the working resource and working temperature of "aged" heaters by using sandwich layers of silicon carbide and molybdenum disilicide is shown.

Asymptotics of the exchange splitting energy for a diatomic molecular ion from a volume integral formula of symmetry-adapted perturbation theory

description: The exchange splitting energy $J$ of the lowest \emph{gerade} and \emph{ungerade} states of the H$_2^+$ molecular ion was calculated using a volume integral expression of symmetry-adapted perturbation theory and standard basis set techniques of quantum chemistry. The performance of the proposed expression was compared to the well known surface integral formula. Both formulas involve the primitive function which we calculated employing either the Hirschfelder-Silbey perturbation theory or the conventional Rayleigh-Schrödinger perturbation theory (the polarization expansion). Our calculations show that very accurate values of $J$ can be obtained using the proposed volume integral formula. When the Hirschfelder-Silbey primitive function is used in both formulas the volume formula gives much more accurate results than the surface integral expression. We also show that using the volume integral formula with the primitive function approximated by Rayleigh-Schrödinger perturbation theory, one correctly obtains only the first four terms in the asymptotic expansion of the exchange splitting energy.

description: Crystallization regimes of the metal in the mold have been developed on the basis of ensuring the formation of a stable structure by processing white cast iron at high temperatures and out-of-furnace processing of liquid metal. The technology of processing liquid metal processed at high temperatures using a modifier containing 3-4% titanium and 1-1.5% molybdenum was developed. Based on of these developed technologies, the issues of obtaining spare parts for pumps and crusher rotors that can resistant to corrosion in the production conditions of “NMZ” enterpriseof Navoi MMC were considered. The analysis showed that in order to increase the performance resource of products obtained by the method of casting in the conditions of the company “NMZ” enterpriseof Navoi MMC, they were offered to use special heat treatment methods.
A Josephson radiation comb generator

description: We propose the implementation of a Josephson Radiation Comb Generator (JRCG) based on a dc superconducting quantum interference device (SQUID) driven by an external magnetic field. When the magnetic flux crosses a diffraction node of the critical current interference pattern, the superconducting phase undergoes a jump of $π$ and a voltage pulse is generated at the extremes of the SQUID. Under periodic drive this allows one to generate a sequence of sharp, evenly spaced voltage pulses. In the frequency domain, this corresponds to a comb-like structure similar to the one exploited in optics and metrology. With this device it is possible to generate up to several hundreds of harmonics of the driving frequency. For example, a chain of $50$ identical high-critical-temperature SQUIDs driven at 1 GHz can deliver up to a $0.5$ nW at 200 GHz. The availability of a fully solid-state radiation comb generator such as the JRCG, easily integrable on chip, may pave the way to a number of technological applications, from metrology to sub-millimeter wave generation.

description: We propose to use quantum coherence as ultimate proof of quantum nature in the radiation that appears by means of the Dynamical Casimir Effect in experiments with superconducting microwave waveguides. We show that, unlike previously considered measurements of quantum correlations such as entanglement and discord, quantum coherence does not require a threshold value of the external pump amplitude and is highly robust to thermal noise.

description: In this paper, we study the effects of high-order operators on the non-relativistic Lifshitz holography in the framework of the Hořava-Lifshitz (HL) theory of gravity, which naturally contains high-order operators in order for the theory to be power-counting renormalizble, and provides an ideal place for such studies. In particular, we show that the Lifshitz space-time is still a solution of the full theory of the HL gravity. The effects of the high-oder operators on the space-time itself is simply to shift the Lifshitz dynamical exponent. However, while in the infrared the asymptotic behavior of a (probe) scalar field near the boundary is similar to that studied in the literature, it gets dramatically modified in the UV limit, because of the presence of the high-order operators in this regime. Then, according to the gauge/gravity duality, this in turn affects the two-point correlation functions.

description: A stationary transport load acts on the surface of the cavity or on the inner surface of the shell supporting the cavity. The speed of the load is accepted subsonic, which corresponds to modern transport speeds in the studied underground structures. To describe the motion of half-space and thick-walled shells, the dynamic equations of the theory of elasticity in Lame potentials are used, and for thin-walled shells, the classical equations of the theory of thin shells are used. The equations are written in a moving coordinate system associated with the load.

description: We analyze over 2.6 million news articles and propose a novel measure of aggregate joint news coverage of firms. The measure strongly and negatively predicts market returns, both in sample and out of sample. The relation is causal, robust to existing predictors, and is especially strong when market uncertainty is high or when market frictions are large. Using data on EDGAR downloads by unique IPs, we provide direct evidence that joint news triggers attention spillover across firms. Our results are consistent with the explanation that joint news generates a contagion in investor attention and causes marketwide overvaluations and subsequent reversals.

Electroweak phase transition in the economical 3-3-1 model

description: We consider the EWPT in the economical 3-3-1 (E331) model. Our analysis shows that the EWPT in the model is a sequence of two first-order phase transitions, $SU(3) \rightarrow SU(2)$ at the TeV scale and $SU(2) \rightarrow U(1)$ at the $100$ GeV scale. The EWPT $SU(3) \rightarrow SU(2)$ is triggered by the new bosons and the exotic quarks; its strength is about $1 - 13$ if the mass ranges of these new particles are $10^2 \,\mathrm{GeV} - 10^3 \,\mathrm{GeV}$. The EWPT $SU(2) \rightarrow U(1)$ is strengthened by only the new bosons; its strength is about $1 - 1.15$ if the mass parts of $H^0_1$, $H^\pm_2$ and $Y^\pm$ are in the ranges $10 \,\mathrm{GeV} - 10^2 \,\mathrm{GeV}$. The contributions of $H^0_1$ and $H^{\pm}_2$ to the strengths of both EWPTs may make them sufficiently strong to provide large deviations from thermal equilibrium and B violation necessary for baryogenesis.

description: The theory of generalized Weyl algebras is used to study the $2\times 2$ reflection equation algebra $\mathcal{A}=\mathcal{A}_q(\operatorname{M}_2)$ in the case that $q$ is not a root of unity, where the $R$-matrix used to define $\mathcal{A}$ is the standard one of type $A$. Simple finite dimensional $\mathcal{A}$-modules are classified, finite dimensional weight modules are shown to be semisimple, $\operatorname{Aut}(\mathcal{A})$ is computed, and the prime spectrum of $\mathcal{A}$ is computed along with its Zariski topology. Finally, it is shown that $\mathcal{A}$ satisfies the Dixmier-Moeglin equivalence.

description: Describing the bosonic AdS_3 x S^3 particle and string in SU(1,1) x SU(2) group variables, we provide a Hamiltonian treatment of the isometry group orbits of solutions via analysis of the pre-symplectic form. For the particle we obtain a one-parameter family of orbits parameterized by creation-annihilation variables, which leads to the Holstein-Primakoff realization of the isometry group generators. The scheme is then applied to spinning string solutions characterized by one winding number in AdS_3 and two winding numbers in S^3. We find a two-parameter family of orbits, where quantization again provides the Holstein-Primakoff realization of the symmetry generators with an oscillator type energy spectrum. Analyzing the minimal energy at strong coupling we verify the spectrum of short strings at special values of winding numbers.

description: We present the results of our Hubble Space Telescope program and describe how our analysis methods were used to re-evaluate the habitability of some of the most interesting Kepler planet candidates. Our program observed 22 Kepler Object of Interest (KOI) host stars, several of which were found to be multiple star systems unresolved by Kepler. We use our high-resolution imaging to spatially resolve the stellar multiplicity of Kepler-296, KOI-2626, and KOI-3049, and develop a conversion to the Kepler photometry (Kp) from the F555W and F775W filters on WFC3/UVIS. The binary system Kepler-296 (5 planets) has a projected separation of 0.217" (80AU); KOI-2626 (1 planet candidate) is a triple star system with a projected separation of 0.201" (70AU) between the primary and secondary components and 0.161" (55AU) between the primary and tertiary; and the binary system KOI-3049 (1 planet candidate) has a projected separation of 0.464" (225AU). We use our measured photometry to fit the separated stellar components to the latest Victoria-Regina Stellar Models with synthetic photometry to conclude that the systems are coeval. The components of the three systems range from mid-K dwarf to mid-M dwarf spectral types. We solved for the planetary properties of each system analytically and via an MCMC algorithm using our independent stellar parameters. The planets range from ~1.6R_Earth to ~4.2R_Earth, mostly Super Earths and mini-Neptunes. As a result of the stellar multiplicity, some planets previously in the Habitable Zone are, in fact, not, and other planets may be habitable depending on their assumed stellar host.
