description: We present and test a new numerical method to determine second-order Lagrangian displacement fields in the context of modified gravity (MG) theories. We start from the extension of Lagrangian Perturbation Theory to a class of MG models that can be described by a parametrized Poisson equation, with the introduction of a scale-dependent function. We exploit fast Fourier transforms to compute the full source term of the differential equation for the second-order Lagrangian displacement field. We compare its mean to the source term computed for specific configurations for which a k-dependent solution can be found numerically. We choose the configuration that best matches the full source term, thus obtaining an approximate factorization of the second-order displacement field as the space term valid for standard gravity times a k-dependent, second-order growth factor $D_2(k,t)$. This approximation is used to compute second order displacements for particles. The method is tested against N-body simulations run with standard and $f(R)$ gravity: we rely on the results of a friends-of-friends code run on the N-body snapshots to assign particles to halos, then compute the halo power spectrum. We find very consistent results for the two gravity theories: second-order LPT (2LPT) allows to recover the halo power spectrum of N-body simulations within $\sim 10\%$ precision to $k\sim 0.2-0.4\ h\ {\rm Mpc}^{-1}$, as well as halo positions, with an error that is a fraction of the inter-particle distance. We show that, when considering the same level of non-linearity in the density field, the performance of 2LPT with MG is the same (within $1\%$) as the one obtained for the standard $Λ$CDM model with General Relativity. When implemented in a computer code, this formulation of 2LPT can quickly generate dark matter distributions with $f(R)$ gravity, and can easily be extended to other MG theories.

description: Helicobacter pylori infection has been associated with the development of insulin resistance (IR). This study aimed to examine the effect of H. pylori-derived extracellular vesicles (EVs) on IR induction. EVs were derived from two H. pylori strains, and characterised by transmission electron microscopy and dynamic light scattering. Different concentrations of insulin were added to HepG2 cells to induce IR model. HepG2 cells were exposed to various concentrations of H. pylori-derived EVs to assess IR development. The gene expression of IRS1, AKT2, GLUT2, IL-6, SOCS3, c-Jun and miR-140 was examined using RT-qPCR. Glucose uptake analysis revealed insulin at 5 × 10 −7 mol/l and EVs at 50 µg/ml induced IR model in HepG2 cells. H. pylori-derived EVs downregulated the expression level of IRS1, AKT2, and GLUT2, and upregulated IL-6, SOCS3, c-Jun, and miR-140 expression in HepG2 cells. In conclusion, our findings propose a novel mechanism by which H. pylori-derived EVs could potentially induce IR.

SiO Maser Survey toward the Inner Galactic Disk: 40 < l < 70 and |b| < 10

description: We present the results of an SiO maser survey for color-selected IRAS sources in the area 40 < l < 70 and |b| < 10 in the SiO J=1-0, v=1 and 2 transitions. We detected 134 out of 272 observed sources in SiO masers; 127 were new detections. A systematic difference in the detection rates between SiO and OH maser searches was found. Especially, in the color ranges with log(F_{25}/F_{12}) smaller than -0.1, the detection rate of the SiO masers is significantly higher than that of OH masers. We found a possible kinematic influence of the galactic arm on the distribution of SiO maser sources. It was found that the velocity dispersion of SiO maser sources tends to decrease with the galactocentric distance. Using the present and previous data of SiO maser surveys, we found that the local velocity gradient of the rotational velocity of the Galaxy is consistent with the values obtained from other kinds of disk population stars within a statistical uncertainty. The Oort's constants, "A" and "B", were computed from the gradient of the rotation curve for the present data, and were consistent with the IAU standard values. In addition, in order to check the reliability of IRAS positions, we observed toward the MSX positions for 5 MSX counterparts, which are located more than 20" away (but within 60") from IRAS positions. We detected all of these 5 sources in SiO masers.

description: In the Comment written by Krasnikov \cite{Krasnikov:2019mrd} on our recent paper \cite{Dai:2019mse}, the author argues that a spherically symmetric perturbation coming from a massive object located on the other side of the wormhole would just add up to the total mass of the central object, and is therefore useless as an indicator of the wormhole presence. We point out that our Eq.~(37) represents an {\it acceleration variation} in the motion of the star S2 due to an elliptic (and thus non-spherically symmetric) orbit of the star on the other side perturbing the metric. This time-dependent acceleration variation is in principle distinguishable from the original acceleration coming from the central object. We also point out that the author is trying to apply Birkhoff's theorem in a setup where it cannot be applied in a straightforward way.

Этот звуковой комплекс дробится на составные части, при чем из плавно следующих друг за другом звуков выделяются основные составляющие слово единицы – фонемы. В акустически сложных словах, включающих безударные гласные, акустически измененные в связи со своей позицией согласные и стечение согласных, этот процесс превращается в сложную деятельность, включающую отвлечение от побочных акустических признаков звуков и выделение устойчивых звуковых единиц. Выделенные в результате такой работы фонемы должны быть расположены в известной последовательности и перешифрованы в соответствующие оптические структуры – графемы.
Linear Dimensions of Adsorbed Semiflexible Polymers: What can be learned about their persistence length?

description: Conformations of partially or fully adsorbed semiflexible polymer chains are studied varying both contour length $L$, chain stiffness, $κ$, and the strength of the adsorption potential over a wide range. Molecular Dynamics simulations show that partially adsorbed chains (with "tails", surface attached "trains" and "loops") are not described by the Kratky-Porod wormlike chain model. The crossover of the persistence length from its three-dimensional value $(\ell_p)$ to the enhanced value in two dimensions $(2\ell_p)$ is analyzed, and excluded volume effects are identified for $L \gg \ell_p$. Consequences for the interpretation of experiments are suggested. We verify the prediction that the adsorption threshold scales as $\ell_p^{-1/3}$.

description: We studied the single dimer dynamics in a lattice diffusive model as a function of particle density in the high densification regime. The mean square displacement is found to be subdiffusive both in one and two dimensions. The spatial dependence of the self part of the van Hove correlation function displays as function of $r$ a single peak and signals a dramatic slow down of the system for high density. The self intermediate scattering function is fitted to the Kohlrausch-Williams-Watts law. The exponent $β$ extracted from the fits is density independent while the relaxation time $τ$ follows a scaling law with an exponent 2.5.

Антимонопольное регулирование закупочной деятельности в российской Федерации основывается на нормативно-правовых и законодательных актах, принципом которых является преобладание публично-общественных интересов над частными. Анализ конкурентного законодательства и позиций современных исследователей показал, что свободная конкуренция имеет недостатки, а существование монополий целесообразно, поскольку именно монополии часто становятся центрами инноваций. Государственная антимонопольная политика направлена на развитие рыночной конкуренции, сдерживание монополизации рынка и развитие отдельных сфер экономики. Для государственного сектора - это экономия бюджетных средств и снижение коррупционных рисков, для предпринимателей - поддержка малого и среднего бизнеса, политика импортозамещения.

description: The World Health Organization describes zoonotic diseases as a major pandemic threat, and modeling the behavior of such diseases is a key component of their control. Many emerging zoonoses, such as SARS, Nipah, and Hendra, mutated from their wild type while circulating in an intermediate host population, usually a domestic species, to become more transmissible among humans, and moreover, this transmission route will only become more likely as agriculture and trade intensifies around the world. Passage through an intermediate host enables many otherwise rare diseases to become better adapted to humans, and so understanding this process with mathematical epidemiological models is necessary to prevent epidemics of emerging zoonoses, guide policy interventions in public health, and predict the behavior of an epidemic. In this paper, we account for spillovers of a zoonotic disease mutating in an intermediate host by means of modeling transmission dynamics within and between three host species, namely, wild reservoir, intermediate domestic animals, and humans. We calculate the basic reproductive number of the pathogen, present critical conditions for the emergence dynamics of zoonosis, and perform stability analysis of admissible disease equilibria. Our analytical results agree well with long-term simulations of the system. We find that in the presence of biologically realistic interspecies transmission parameters, a zoonotic disease can establish itself in humans even if it fails to persist in its reservoir and intermediate host species. Our model and results can be used to understand the dynamic behavior of any zoonosis with intermediate hosts and assist efforts to protect public health.

description: While the competitiveness of the Canadian agri-food sector attracted significant research attention since the mid 1980s, no study has measured competitiveness using longitudinal data and determined empirically the drivers of competitiveness. This article contributes to the competitiveness literature by measuring the international competitiveness of wheat, beef and pork sectors in Canada using data from 1961 to 2011 and by determining the drivers of competitiveness. Our results demonstrate that Canada enjoys competitiveness in the wheat sector but not in the beef or pork sectors. Empirical results also suggest that the competitiveness of the Canadian wheat sector can be enhanced if the cost seed in Canada relative to that in the United States is lower. Similarly, if the relative labour cost of meat processing is lower, the competitiveness of both beef and pork sectors in Canada will be enhanced. Exchange rates are important drivers of international competitiveness of beef and pork sectors in Canada. The decoupled farm policies in Canada do not have a significant impact on the competitiveness of wheat and pork sectors in Canada. Our empirical results also highlight cases of significant policy failures in Canada.

description: The implementation of a new particle module describing the physics of dust grains coupled to the gas via drag forces is the subject of this work. The proposed particle-gas hybrid scheme has been designed to work in Cartesian as well as in cylindrical and spherical geometries. The numerical method relies on a Godunov-type second-order scheme for the fluid and an exponential midpoint rule for dust particles which overcomes the stiffness introduced by the linear coupling term. Besides being time-reversible and globally second-order accurate in time, the exponential integrator provides energy errors which are always bounded and it remains stable in the limit of arbitrarily small particle stopping times yielding the correct asymptotic solution. Such properties make this method preferable to the more widely used semi-implicit or fully implicit schemes at a very modest increase in computational cost. Coupling between particles and grid quantities is achieved through particle deposition and field-weighting techniques borrowed from Particle-In-Cell simulation methods. In this respect, we derive new weight factors in curvilinear coordinates that are more accurate than traditional volume- or area-weighting. A comprehensive suite of numerical benchmarks is presented to assess the accuracy and robustness of the algorithm in Cartesian, cylindrical and spherical coordinates. Particular attention is devoted to the streaming instability which is analyzed in both local and global disk models. The module is part of the PLUTO code for astrophysical gas-dynamics and it is mainly intended for the numerical modeling of protoplanetary disks in which solid and gas interact via aerodynamic drag.

description: В статье раскрывается понимание того, что важность и актуальность использования маркетинга территорий для успеха реализации программных стратегий социально-экономического развития территорий сложно переоценить, поскольку залогом привлечения финансовых, экономических и демографических ресурсов в регион случит его привлекательность в глазах потребителей, к которым в широком смысле относятся как бизнес и население, так и органы государственной и муниципальной власти, в том числе принимающие решение об инвестировании средств, выборе места работы, места жительства, места отдыха, наконец, о размещении объектов народного хозяйства, создании промышленных и транспортных узлов, ареалов расселения населения. Основой формирования привлекательности территории в глазах всех категорий потребителей служит её бренд-идентификация в системе территориального брендинга.

Формирование целостного и равномерно и поступательно развивающегося экономического пространства позволяет значительно повысить уникальные территориальные черты каждого «места» и его репутационную привлекательность в соперничестве за приток ограниченных ресурсов, важным инструментом чего выступают региональные бренды. Условия экономической неопределенности, вызванные внешним сдерживанием экономического роста России и функционирование экономики в условиях пандемии COVID-19, вскрывают внутренние резервы развития экономики регионов.

description: We study the time evolution of a rotating condensate, that expands after being suddenly released from the confining trap, by solving the hydrodynamic equations of irrotational superfluids. For slow initial rotation speeds, $Ω_{0}$, we find that the condensate's angular velocity increases rapidly to a maximum value and this is accompanied by a minimum in the deformation of the condensate in the rotating plane. During the expansion the sample makes a global rotation of approximately $π/2$, where the exact value depends on $Ω_{0}$. This minimum deformation can serve as an easily detectable signature of superfluidity in a Bose--Einstein condensate.

Three-dimensional MHD Simulations of Radiatively Inefficient Accretion Flows

description: We present three-dimensional MHD simulations of rotating radiatively inefficient accretion flows onto black holes. In the simulations, we continuously inject magnetized matter into the computational domain near the outer boundary, and we run the calculations long enough for the resulting accretion flow to reach a quasi-steady state. We have studied two limiting cases for the geometry of the injected magnetic field: pure toroidal field and pure poloidal field. In the case of toroidal field injection, the accreting matter forms a nearly axisymmetric, geometrically-thick, turbulent accretion disk. The disk resembles in many respects the convection-dominated accretion flows found in previous numerical and analytical investigations of viscous hydrodynamic flows. Models with poloidal field injection evolve through two distinct phases. In an initial transient phase, the flow forms a relatively flattened, quasi-Keplerian disk with a hot corona and a bipolar outflow. However, when the flow later achieves steady state, it changes in character completely. The magnetized accreting gas becomes two-phase, with most of the volume being dominated by a strong dipolar magnetic field from which a thermal low-density wind flows out. Accretion occurs mainly via narrow slowly-rotating radial streams which `diffuse' through the magnetic field with the help of magnetic reconnection events.

description: The Planck constant, with its mathematical symbol $h$, is a fundamental constant in quantum mechanics that is associated with the quantization of light and matter. It is also of fundamental importance to metrology, such as the definition of ohm and volt, and the latest definition of kilogram. One of the first measurements to determine the Planck constant is based on the photoelectric effect, however, the values thus obtained so far have exhibited a large uncertainty. The accepted value of the Planck constant, 6.62607015$\times$10$^{-34}$ J$\cdot$s, is obtained from one of the most precise methods, the Kibble balance, which involves quantum Hall effect, Josephson effect and the use of the International Prototype of the Kilogram (IPK) or its copies. Here we present a precise determination of the Planck constant by modern photoemission spectroscopy technique. Through the direct use of the Einstein's photoelectric equation, the Planck constant is determined by measuring accurately the energy position of the gold Fermi level using light sources with various photon wavelengths. The precision of the measured Planck constant, 6.62610(13)$\times$10$^{-34}$ J$\cdot$s, is four to five orders of magnitude improved from the previous photoelectric effect measurements. It has rendered photoemission method to become one of the most accurate methods in determining the Planck constant. We propose that this direct method of photoemission spectroscopy has advantages and a potential to further increase its measurement precision of the Planck constant to be comparable to the most accurate methods that are available at present.

description: We examine the ground state properties of the s=1/2 transverse Ising chain with regularly alternating bonds and fields using exact analytical results and exact numerical data for long (up to N=900) and short (N=20) chains. For a given period of alternation the system may exhibit a series of quantum phase transitions, where the number of transitions depends on the concrete set of the parameters of the Hamiltonian. The critical behaviour for the nonuniform and the uniform chain is the same.

description: This study examined the effects of hyperthermic therapy (HT) on mice fed normal chow or a high-fat diet (HFD) for 18 or 22 weeks, undergoing four or eight weekly HT sessions. Mice were housed within their thermoneutral zone (TNZ) to simulate a physiological response. HFD-induced obesity-related changes, including weight gain, visceral fat accumulation, muscle loss (indicative of obesity sarcopenia), glucose intolerance, and hepatic triglyceride buildup. HT upregulated HSP70 expression in muscles, mitigated weight gain, normalised QUICK index, and reduced plasma HSP70 concentrations. It also lowered the H-index of HSP70 balance, indicating improved immunoinflammatory status, and decreased activated caspase-1 and proliferative senescence in adipose tissue, both linked to insulin resistance. The findings suggest that even animals on a “control” diet but with insufficient physical activity and within their TNZ may experience impaired glycaemic homeostasis.

description: We describe an ab initio method for calculating the electronic structure, electronic transport, and forces acting on the atoms, for atomic scale systems connected to semi-infinite electrodes and with an applied voltage bias. Our method is based on the density functional theory (DFT) as implemented in the well tested Siesta approach (which uses non-local norm-conserving pseudopotentials to describe the effect of the core electrons, and linear combination of finite-range numerical atomic orbitals to describe the valence states). We fully deal with the atomistic structure of the whole system, treating both the contact and the electrodes on the same footing. The effect of the finite bias (including selfconsistency and the solution of the electrostatic problem) is taken into account using nonequilibrium Green's functions. We relate the nonequilibrium Green's function expressions to the more transparent scheme involving the scattering states. As an illustration, the method is applied to three systems where we are able to compare our results to earlier ab initio DFT calculations or experiments, and we point out differences between this method and existing schemes. The systems considered are: (1) single atom carbon wires connected to aluminum electrodes with extended or finite cross section, (2) single atom gold wires, and finally (3) large carbon nanotube systems with point defects.

Fluctuation Effects in Mixed State of Type II Superconductor. Comparison of Experimental Results with Theoretical Predictions

description: Results of the investigation of fluctuation phenomena in bulk type-II superconductors obtained in 1980 - 1984 years are compared with the analogous results obtained at the investigation of high-Tc superconductors (HTSC). It is shown the latter repeat in the main the results obtained before the HTSC discovery. It was discovered in 1981 year that a sharp change of resistive properties is observed below the second critical field, at H_{c4} < H_{c2}, in high quality samples of type-II superconductors. The same was repeated at investigation of high quality HTSC samples and was interpreted as vortex lattice melting. The difference of the (H_{c2} - H_{c4}) values for low- and high-Tc superconductors corresponds with the scaling law obtained in the lowest Landau level approximation. The linear approximation region above H_{c2}, the critical region and the Abrikosov state are considered. It is emphasized that the rigorous Ami-Maki theory should be used for description of paraconductivity in HTSC and "dirty" conventional superconductors. The approximation dependencies obtained from popular Aslamasov-Larkin, Hikami-Larkin and Lawrence-Doniac works do not have a validity region in these superconductors with wide critical region.
