strength

description: The strength of fine-grained concrete was studied, for the production of which water was used, which was structured by adding non-electrolytes. It is determined that due to the structuring of water in its composition in-creased the content of protons, which accelerate the hydration reaction of cement minerals, as well as destroy the flocs of cement particles. The optimal amount of these substances, which are not electrolytes, allows you to control the rheological properties of concrete mixtures and modify the structure of cement stone so as to ensure the prop-erties of concrete, which provide high operational reliability of structures. The aim of the study is to determine the effect of reaction powders used simultaneously with non-electrolytes on the strength of fine-grained concrete and the rate of its formation

description: New South Wales Government's 1995 water reform proposals included several environmental flow policies aimed at improving water quality and the river ecosystems. In evaluating these policies a number of different river flow objectives were considered some of which resulted in a reduction in the water availability for irrigated agriculture. This paper discusses the methodology and modelling framework adopted to analyze the economic impacts of environmental flow policies on the Macquarie regional economy of NSW. An economic model (Catchment Economic Impact Model) was developed to estimate these impacts. This model combines hydrology, simulation, spreadsheet and linear programming applications. The objective function of the linear programming model is to maximize the total gross margins for the region. Constraints include prices, costs, land, labour, and water availability. The model provides economic impacts in the format of descriptive statistics of total gross margin, total irrigated regional gross margin, present value of total regional gross margin over a 30 year period and changes in crop areas under different environmental flow objectives. Four different river flow objectives represented by six hydrology scenarios were considered in this analysis. The results of the preliminary analysis of these objectives are also discussed in this paper.

description: The Stock Market is a complex self-interacting system, characterized by an intermittent behaviour. Periods of high activity alternate with periods of relative calm. In the present work we investigate empirically about the possibility that the market is in a self-organized critical state (SOC). A wavelet transform method is used in order to separate high activity periods, related to the avalanches of sandpile models, from quiescent. A statistical analysis of the filtered data show a power law behaviour in the avalanche size, duration and laminar times. The memory process, implied by the power law distribution, of the laminar times is not consistent with classical conservative models for self-organized criticality. We argue that a ``near-SOC'' state or a time dependence in the driver, which may be chaotic, can explain this behaviour.

description: The evolution of the structural and transport properties of underdoped La$_{1.952}$Sr$_{0.048}$CuO$_4$ thin films under compressive epitaxial strain has been studied. The films of different thicknesses $d$ (from 26 nm to 120 nm) were deposited using an insulating target. The onset of superconductivity in the films is observed at temperatures as high as 26 K, while small residual resistance persists at low temperatures, indicating that superconductivity is inhomogeneous. The resistance measured under perpendicular magnetic field saturates below about 0.65 K, suggesting a possible existence of nonconventional metallic state. The magnetic-field-tuned superconductor-insulator transition is observed at magnetic field of about 32 T.

description: Choushenpilosulynes D–G (1-4): four new polyynes were isolated from the roots of Codonopsis pilosula (Campanulaceae) cultivated in Yunnan province, China. Their structures were identified by spectroscopic methods. Bioactive evaluation showed that choushenpilosulynes E (2) and F (3) demonstrated potent inhibitory effect on lipid formation induced by 100 μM oleic acid stimulation. In addition, choushenpilosulyne F (3) uncovered inhibitory activity against the expression of human 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) and squalene monooxygenase (SQLE) gene transcript in HepG2 cells.

description: (Abridged) While the gravitational-wave (GW) signal GW170817 was accompanied by a variety of electromagnetic (EM) counterparts, sufficiently high-mass binary neutron star (BNS) mergers are expected to be unable to power bright EM counterparts. The putative high-mass binary BNS merger GW190425, for which no confirmed EM counterpart has been identified, may be an example of such a system. It is thus important to understand how well we will be able to distinguish high-mass BNSs and low-mass binary black holes (BBHs) solely from their GW signals. To do this, we consider the imprint of the tidal deformability of the neutron stars on the GW signal for systems undergoing prompt black hole formation after merger. We model the BNS signals using hybrid numerical relativity -- tidal effective-one-body waveforms. Specifically, we consider a set of five nonspinning equal-mass BNS signals with masses of 2.7, 3.0, 3.2 Msun and with three different equations of state, as well as the analogous BBH signals. We perform parameter estimation on these signals in three networks: Advanced LIGO-Advanced Virgo and Advanced LIGO-Advanced Virgo-KAGRA with sensitivities similar to O3 and O4, respectively, and a 3G network of two Cosmic Explorers (CEs) and one Einstein Telescope, with a CE sensitivity similar to Stage 2. Our analysis suggests that we cannot distinguish the signals from high-mass BNSs and BBHs at a 90% credible level with the O3-like network even at 40 Mpc. However, we can distinguish all but the most compact BNSs that we consider in our study from BBHs at 40 Mpc at a >= 95% credible level using the O4-like network, and can even distinguish them at a > 99.2% (>= 97%) credible level at 369 (835) Mpc using the 3G network. Additionally, we present a simple method to compute the leading effect of the Earth's rotation on the response of a gravitational wave detector in the frequency domain.

description: We establish universality of local eigenvalue correlations in unitary random matrix ensembles (1/Z_n) |\det M|^{2α} e^{-n\tr V(M)} dM near the origin of the spectrum. If V is even, and if the recurrence coefficients of the orthogonal polynomials associated with |x|^{2α} e^{-nV(x)} have a regular limiting behavior, then it is known from work of Akemann et al., and Kanzieper and Freilikher that the local eigenvalue correlations have universal behavior described in terms of Bessel functions. We extend this to a much wider class of confining potentials V. Our approach is based on the steepest descent method of Deift and Zhou for the asymptotic analysis of Riemann-Hilbert problems. This method was used by Deift et al. to establish universality in the bulk of the spectrum. A main part of the present work is devoted to the analysis of a local Riemann-Hilbert problem near the origin.

description: We study the even spin $\mathcal{W}_\infty$ which is a universal $\mathcal{W}$-algebra for orthosymplectic series of $\mathcal{W}$-algebras. We use the results of Fateev and Lukyanov to embed the algebra into $\mathcal{W}_{1+\infty}$. Choosing the generators to be quadratic in those of $\mathcal{W}_{1+\infty}$, we find that the algebra has quadratic operator product expansions. Truncations of the universal algebra include principal Drinfeľd-Sokolov reductions of $BCD$ series of simple Lie algebras, orthogonal and symplectic cosets as well as orthosymplectic $Y$-algebras of Gaiotto and Rapčák. Based on explicit calculations we conjecture a complete list of co-dimension $1$ truncations of the algebra.

description: Density fluctuations of expanding nuclear matter are studied within a mean-field model in which fluctuations are generated by an external stochastic field. Fluctuations develop about a mean one-body phase-space density corresponding to a hydrodinamic motion that describes a slow expansion of the system. A fluctuation-dissipation relation suitable for a uniformly expanding medium is obtained and used to constrain the strength of the stochastic field. The distribution of the liquid domains in the spinodal decomposition is derived. Comparison of the related distribution of the fragment size with experimental data on the nuclear multifragmentation is quite satisfactory.

We focus on the Poisson problem on two dimensional computational domains. We provide a convergence analysis that covers several choices of the primal degrees of freedom: the vertex values, the edge averages, and the combination of both. We derive condition number bounds that show the expected behavior in the grid size h and that are quasi-linear in the spline degree p.

Invasion rate versus diversity in population dynamics with catastrophes

description: A key question in the current diversity crisis is how diversity has been maintained throughout evolution and how to preserve it. Modern coexistence theories suggest that a high invasion rate of rare new types is directly related to diversity. We show that adding almost any mechanism of catastrophes to a stochastic birth, death, and mutation process with limited carrying capacity induces a novel phase transition characterized by a positive invasion rate but a low diversity. In this phase, new types emerge and grow rapidly, but the resulting growth of very large types decreases diversity. This model also resolves two major drawbacks of neutral evolution models: their failure to explain balancing selection without resorting to fitness differences and the unrealistic time required for the creation of the observed large types. We test this model on a classical case of genetic polymorphism: the HLA locus.

description: We compute the average shape of trajectories of some one--dimensional stochastic processes x(t) in the (t,x) plane during an excursion, i.e. between two successive returns to a reference value, finding that it obeys a scaling form. For uncorrelated random walks the average shape is semicircular, independently from the single increments distribution, as long as it is symmetric. Such universality extends to biased random walks and Levy flights, with the exception of a particular class of biased Levy flights. Adding a linear damping term destroys scaling and leads asymptotically to flat excursions. The introduction of short and long ranged noise correlations induces non trivial asymmetric shapes, which are studied numerically.

description: Recently there have been a number of experiments on Ce$_2$Zr$_2$O$_7$ and Ce$_2$Sn$_2$O$_7$, suggesting that these materials host a three-dimensional quantum spin liquid with emergent photons and fractionalized spinon excitations. However, the interpretation of the data to determine the precise nature of the quantum spin liquids is still under debate. The Kramers doublet in Ce$^{3+}$ local moment offers unusual pseudo-spin degrees of freedom as the $x$ and $z$ components transform as a dipole and $y$ component as an octupole. This leads to a variety of possible quantum spin liquid (or quantum spin ice) phases on the pyrochlore lattice of Ce$^{3+}$ moments. In this work, we theoretically propose that magnetostriction would be able to distinguish the dipolar (D-QSI) and octupolar (O-QSI) quantum spin ice, where the dipolar or octupolar components possess the respective spin ice correlations. We show that the magnetostriction in various configurations can be used as a selection rule to differentiate not only D-QSI and O-QSI, but also a number of competing broken symmetry states.

We strictly prove that the diameter of networks has a constant upper bound independent to the network size $N$, which is completely different from the extensively studied real-life networks with their average distance increasing logarithmically to $N$ as $L\sim \texttt{ln}N$ or $L\sim \texttt{lnln}N$. Further more, the integer networks is high clustered, with clustered coefficient $C\approx 0.34$, and display power-law degree distribution of exponent $γ\approx 2.4$.

Cold Dark Matter's Small Scale Crisis Grows Up

description: The Cold Dark Matter (CDM) theory predicts a wealth of substructure within dark halos. These predictions match observations of galaxy clusters like the nearby Virgo cluster. However, CDM has a "small scale crisis" since galaxies dominate the halo with little substructure while the model predicts that galaxies should be scaled versions of galaxy clusters with abundant substructure. Compared to CDM predictions, the Milky Way and Andromeda are "missing" objects with velocity dispersions $σ\geq 10$ km s$^{-1}$. The energy scale of these missing satellites is low enough that stellar winds and supernovae might remove gas and suppress the formation of their luminous stellar components. Here, we show that the small scale crisis persists in fossil groups that have masses of up to 40% of the nearby Virgo cluster of galaxies. Fossil groups are missing satellites with luminosities that occur at the predicted frequency in the Virgo cluster. Moreover, the "missing galaxies" in fossil groups are nearly as luminous as the Milky Way with a velocity dispersion $σ\leq$ 150 km s$^{-1}$.

description: While translating between East Asian languages, many works have discovered clear advantages of using characters as the translation unit. Unfortunately, traditional recurrent neural machine translation systems hinder the practical usage of those character-based systems due to their architectural limitations. They are unfavorable in handling extremely long sequences as well as highly restricted in parallelizing the computations. In this paper, we demonstrate that the new transformer architecture can perform character-based translation better than the recurrent one. We conduct experiments on a low-resource language pair: Japanese-Vietnamese. Our models considerably outperform the state-of-the-art systems which employ word-based recurrent architectures.

description: Stroke survivors and their partners experience changes in sexuality after experiencing a stroke. However, there is limited research into how stroke can change the experience of sexuality among LGBTQI+ stroke survivors and their partners. The aim of this study was to explore the experiences of sex and sexuality among LGBTQI+ stroke survivors and their partners post-stroke. A qualitative phenomenological research design was used to explore the experiences of the participants. Interpretative Phenomenological Analysis (IPA) was used for the analysis of the data. Stroke survivors (n = 18) and partners of stroke survivors (n = 5) completed interviews where they were asked about their experiences of sex and sexuality post-stroke. Four main themes were identified which explored impact on sexual functioning, changes in sexual activity and behavior, relationships post-stroke and access to the LGBTQI+ community. Stroke survivors and their partners experienced negative changes in sexuality post-stroke. This study presents experiences previously not explored in existing stroke literature. The findings of the study can assist in the development of effective sexual rehabilitation interventions to help LGBTQI+ stroke survivors and their partners reclaim their sexuality post-stroke. LGBTQI+ persons are poorly served by existing approaches to sexual rehabilitation following stroke.Some stroke survivors and their partners have successfully navigated the impact of stroke on sexuality, but for many stroke results in ongoing feelings of perceived unattractiveness, withdrawal from sexual activity and relationship breakdown and loss.Rehabilitation professionals need to reflect on the degree to which interventions for sexuality post stroke are inclusive of and useful to LGBTQI+ stroke survivors.Adopting a strengths based approach which builds upon experiences of stroke survivors is critical to ensuring development of inclusive sexual rehabilitation services in the future LGBTQI+ persons are poorly served by existing approaches to sexual rehabilitation following stroke.

description: We present data from a Chandra observation of the nearby cluster of galaxies Abell 576. The core of the cluster shows a significant departure from dynamical equilibrium. We show that this core gas is most likely the remnant of a merging subcluster, which has been stripped of much of its gas, depositing a stream of gas behind it in the main cluster. The unstripped remnant of the subcluster is characterized by a different temperature, density and metalicity than that of the surrounding main cluster, suggesting its distinct origin. Continual dissipation of the kinetic energy of this minor merger may be sufficient to counteract most cooling in the main cluster over the lifetime of the merger event.

description: In the work, the activity of 9 catalysts with an atomic ratio of elements from Mo–W = 1:9 to Mo–W = 9: 1 were studied in the reaction of oxidation of ethanol. The formation of two phases is observed in all samples, namely, the initial molybdenum and tungsten oxides It was found that in the Mo-W-O system, an increase in the degree of crystallinity of binary molybdenum-tungsten oxide catalysts accelerates the formation of ethylene and reduces the yields of acetic aldehyde.

description: The 90 residents of the Carpathian region have been examined within the framework of given study. The patients were divided into such groups: group I – having no thyroid pathology control group (n = 50), group II patients with diagnosed nodular goiter study group (n = 20), group III patients with diffuse endemic goiter (n = 20). As shown by the research performed, the ioduria median was 100.45 μg/l in the examined patients of the control group, 81.5 μg/l in the study group of patients with nodular goiter and 66.4 μg/l in the group of patients with diffuse goiter, which indicated the presence of mild iodine deficiency. In patients with nodular goiter and diffuse endemic goiter, the reduced level of selenium (p<0.05) was found in blood serum and hair. In the examined patients with nodular goiter, the median value of selenium in blood serum was 0.044 mg/l; in hair it was 0.18 μg/g; in patients with diffuse endemic goiter, the median value of selenium in blood was 0.082 mg/l; in hair it was 0.4 mg/l as compared with the corresponding indices in the control group. The median value of zinc and copper content in blood serum and hair did not significantly differ in all groups. The relative risk (RR) of nodular goiter develop-ment at low selenium content in blood was 1.5 mg/g (p<0.1-0.2); at low copper content in blood it was 1.5 mg/g (p<0.1-0.2). At low selenium level in hair, the relative risk (RR) was 1.4 μg/g (p<0.1-0.2) and al low copper level in hair the RR was 1.5 μg/g (p<0.1-0.2).

description: Understanding complex systems with their reduced model is one of the central roles in scientific activities. Although physics has greatly been developed with the physical insights of physicists, it is sometimes challenging to build a reduced model of such complex systems on the basis of insights alone. We propose a novel framework that can infer the hidden conservation laws of a complex system from deep neural networks (DNNs) that have been trained with physical data of the system. The purpose of the proposed framework is not to analyze physical data with deep learning, but to extract interpretable physical information from trained DNNs. With Noether's theorem and by an efficient sampling method, the proposed framework infers conservation laws by extracting symmetries of dynamics from trained DNNs. The proposed framework is developed by deriving the relationship between a manifold structure of time-series dataset and the necessary conditions for Noether's theorem. The feasibility of the proposed framework has been verified in some primitive cases for which the conservation law is well known. We also apply the proposed framework to conservation law estimation for a more practical case that is a large-scale collective motion system in the metastable state, and we obtain a result consistent with that of a previous study.

description: In many organisms, changes in environmental conditions trigger modifications in physiology and signaling for reproduction. In males, sexual maturation often prompts signaling that can convey information on fighting ability and mate quality, allowing adaptative sexual selection to act. Because predation can drive the evolution of sexual signals, insights from organisms exposed to low predation pressure will benefit sexual selection theory. Here, we exposed males and females of Microsternarchus sp. nov. “Ducke” (Gymnotiformes Hypopomidae) to simulate environmental conditions of the breeding season to investigate changes in electric signaling in a species that occurs in environments with low or absent predation pressure from electroreceptive predators. We induced sexual maturation, which was confirmed by visual inspection of female gonads. After sexual maturation, both sexes underwent major changes in Electric Organ Discharges (EOD), suggesting mutual signaling in electric communication before breeding pair formation. EOD parameters related to body length were intensified in sexually mature males and, as such, changes in male electric discharges observed after gonadal maturation exaggerate information on fighting ability and mate quality, as suggested for other electric fishes. Because polarity imbalance was high in both sexes and reproductive stages, our results support the hypothesis that predation pressure did not constrain the evolution of conspicuous EODs in this species, in favor of other adaptive mechanisms of mate choice.

description: The integrals of motion of the tricritical Ising model are obtained by Thermodynamic Bethe Ansatz (TBA) equations derived from the A_4 integrable lattice model. They are compared with those given by the conformal field theory leading to a unique one-to-one lattice-conformal correspondence. They can also be followed along the renormalization group flows generated by the action of the boundary field ϕ_{1,3} on conformal boundary conditions in close analogy to the usual TBA description of energies.

Price Effects of a Lack of Speculation

description: The theoretical proposition that profitable speculation is pricestabilizing is not subject to direct empirical testing in the context of commodity futures markets. The reasons for this are twofold: (1) if all commodity futures trading is viewed as speculation, then this is a zero-sum game which moots the question of profitability; yet (2) if only that trading which is classified as speculation, in contradistinction to hedging, be considered, then the stabilizing effect is seen to be indirect, since it is the hedgers who perform the relevant temporal reallocation of stocks. Evidence of the price effects of speculation in commodity futures contracts is therefore sought in terms of the facilitation of hedging. A convenient and important case is provided by the three active American wheat futures markets-at Chicago, Kansas City, and Minneapolis. It is demonstrated here that the two latter markets, with low levels of speculation, are able to absorb the hedging positions which come to them only because substantial speculation is transfused from Chicago, through spreading. Evidence is also adduced to show that this spreading responds directly to hedging pressures, instead of reflecting price forecasts. Vocational speculation, by floor members of the commodity exchanges, also reflects the anticipation of hedging requirements. Although the data do not allow direct estimates of hedging costs, they strongly support the conclusion that these costs are lower on those markets having more speculation. The conclusion as to the price effects of speculation in commodity futures is then that with ample speculation there is no price effect, whereas the price effect of speculative deficiency is substantial.
