description: We constrain the orbital period ($P_{\rm orb}$) distribution of low-mass detached main-sequence eclipsing binaries (EBs) with light curves from the Zwicky Transient Facility (ZTF), which provides a well-understood selection function and sensitivity to faint stars. At short periods ($P_{\rm orb}\lesssim 2$ days), binaries are predicted to evolve significantly due to magnetic braking (MB), which shrinks orbits and ultimately brings detached binaries into contact. The period distribution is thus a sensitive probe of MB. We find that the intrinsic period distribution of low-mass ($0.1\lesssim M_1/M_{\odot} < 0.9$) binaries is basically flat (${\rm d}N/{\rm d}P_{\rm orb} \propto P_{\rm orb}^0$), from $P_{\rm orb}=10$ days down to the contact limit. This is strongly inconsistent with predictions of classical MB models based on the Skumanich relation, which are widely used in binary evolution calculations and predict ${\rm d}N/{\rm d}P_{\rm orb} \propto P_{\rm orb}^{7/3}$ at short periods. The observed distributions are best reproduced by models in which the magnetic field saturates at short periods, with a MB torque that scales roughly as $\dot{J}\propto P_{\rm orb}^{-1}$, as opposed to $\dot{J} \propto P_{\rm orb}^{-3}$ in the standard Skumanich law. We also find no significant difference between the period distributions of binaries containing fully and partially convective stars. Our results confirm that a saturated MB law, which was previously found to describe the spin-down of rapidly rotating isolated M dwarfs, also operates in tidally locked binaries. We advocate using saturated MB models in binary evolution calculations. Our work supports previous suggestions that MB in cataclysmic variables (CVs) is much weaker than assumed in the standard evolutionary model, unless mass transfer leads to significant additional angular momentum loss in CVs.

description: On subsets E of the Mandelbrot set M, homeomorphisms are constructed by quasi-conformal surgery. When the dynamics of quadratic polynomials is changed piecewise by a combinatorial construction, a general theorem yields the corresponding homeomorphism h: E to E in the parameter plane. Each h has two fixed points in E, and a countable family of mutually homeomorphic fundamental domains. Possible generalizations to other families of polynomials or rational mappings are discussed. The homeomorphisms on subsets E of M constructed by surgery are extended to homeomorphisms of M, and employed to study groups of non-trivial homeomorphisms h: M to M . It is shown that these groups have the cardinality of the continuum, and they are not compact.

description: It is a new field to arouse the motive force of poverty alleviation and improve the poverty alleviation performance research by actively mobilizing enterprises to participate in poverty alleviation and development. In the context of mass entrepreneurship and innovation, the innovation research has already formed the perfect union with the theories related to management science and the economics, but its combination with the sociology, especially with the enterprise-led poverty alleviation research is also very scarce. Under the premise of affirming the mode of enterprise participation in poverty alleviation, this paper explores and analyzes the practical value of this model in three aspects: innovating poverty alleviation model, enhancing the poor people's self-restoration ability, weakening the dual structure of urban and rural areas. This paper clarifies the internal relations among the subjects under the model. This paper also puts forward the innovation direction of poverty alleviation by enterprises in the future in big data focusing, innovative thinking embedding, model innovation, information feedback of the main body, which provides a theoretical basis and direction guidance for the follow-up related research.

description: After entering into WTO, export volume of agricultural products in China quickly increases, but its proportion in total trade volume becomes lower and lower, and there are more and more trade barriers of agricultural products. In this paper, based on the data during 1994-2016, error correction model is established to test and analyze the relationship between economic growth and export of agricultural products in China. The results show that change of agricultural products export in China has positive impact on GDP in short time, and they also have long-term stable relationship. When they lag for different periods, economic growth and export of agricultural products have unidirectional causality.

description: We compare the BFGS optimizer, ADAM and Natural Gradient Descent (NatGrad) in the context of Variational Quantum Eigensolvers (VQEs). We systematically analyze their performance on the QAOA ansatz for the Transverse Field Ising Model (TFIM) as well as on overparametrized circuits with the ability to break the symmetry of the Hamiltonian. The BFGS algorithm is frequently unable to find a global minimum for systems beyond about 20 spins and ADAM easily gets trapped in local minima. On the other hand, NatGrad shows stable performance on all considered system sizes, albeit at a significantly higher cost per epoch. In sharp contrast to most classical gradient based learning, the performance of all optimizers is found to decrease upon seemingly benign overparametrization of the ansatz class, with BFGS and ADAM failing more often and more severely than NatGrad. Additional tests for the Heisenberg XXZ model corroborate the accuracy problems of BFGS in high dimensions, but they reveal some shortcomings of NatGrad as well. Our results suggest that great care needs to be taken in the choice of gradient based optimizers and the parametrization for VQEs.

description: Coarse-grained modeling and efficient computer simulations are critical to the study of complex molecular processes with many degrees of freedom and multiple spatiotemporal scales. Variational implicit-solvent model (VISM) for biomolecular solvation is such a modeling framework, and its initial success has been demonstrated consistently. In VISM, an effective free-energy functional of solute-solvent interfaces is minimized, and the surface energy is a key component of the free energy. In this work, we extend VISM to include the solute mechanical interactions, and develop fast algorithms and GPU implementation for the extended variational explicit-solute implicit-solvent (VESIS) molecular simulations to determine the underlying molecular equilibrium conformations. We employ a fast binary level-set method for minimizing the solvation free energy of solute-solvent interfaces and construct an adaptive-mobility gradient descent method for solute atomic optimization. We also implement our methods in GPU. Numerical tests and applications to several molecular systems verify the accuracy, stability, and efficiency of our methods and algorithms. It is found that our new methods and GPU implementation improve the efficiency of the molecular simulation significantly over the CPU implementation. Our fast computational techniques may enable us to simulate very large systems such as protein-protein interactions and membrane dynamics for which explicit-solvent all-atom molecular dynamics simulations can be very expensive.

description: The pseudogap Anderson impurity model provides a classic example of an essentially local quantum phase transition. Here we study its single-particle dynamics in the vicinity of the symmetric quantum critical point (QCP) separating generalized Fermi liquid and local moment phases, via the local moment approach. Both phases are shown to be characterized by a low-energy scale that vanishes at the QCP; and the universal scaling spectra, on all energy scales, are obtained analytically. The spectrum precisely at the QCP is also obtained; its form showing clearly the non-Fermi liquid, interacting nature of the fixed point.

description: Our knowledge of the high-energy emission spectra from black-hole candidates has increased enormously with missions like BeppoSAX and RossiXTE, thanks to their broad-band window. I present the main and most solid points of this current knowledge, both in terms of detailed spectral modeling of X-ray broad-band spectra, and more generally in relation to the "black-hole state paradigm", which links spectral and timing properties of accretion disks. Finally, through the discussion of recent results on two systems, XTE J1650-500 and GX 339-4, I present evidence for a new view of the state paradigm.

description: Under the resource constraint of low per capita possession of cultivated land and the strategic requirements for ensuring national food security, the intensive and efficient use of cultivated land is an important topic for long-term research in China’s academic circles. It is an important prerequisite for exploring the moderate scale management of agricultural land. The calculation results of 147 county-level units in Northeast China by DEA method show that in the use efficiency evaluation results of cultivated land of county-level units, the mean values of comprehensive efficiency, pure technical efficiency and scale efficiency were 0.674, 0.705 and 0.96, respectively, and the DEA effective units account for about 11%. The effective areas of pure technical efficiency and scale efficiency do not have a high level of superposition. To a certain extent, this also limits the improvement of overall efficiency. In view of the scale of family farmland management, counties and cities with an average per household possession of cultivated land of 1.71-2.13 ha can achieve both scale and efficiency through efficiency improvement.

description: We propose a new mechanism for magnetic field generation from inflation, by which strong magnetic fields can be generated on cosmological scales. These fields may be observable by cosmic microwave background radition measurements, and may have a dynamical impact on structure formation. The mechanism is based on the observation that a light nearly minimally coupled charged scalar may be responsible for the creation of a negative photon mass-squared (provided the scalar field coupling to the curvature scalar is small but negative), which in turn results in abundant photon production - and thus in growing magnetic fields - during inflation.

description: The solar convection zone rotates differentially, with its equatorial region rotating more rapidly than the polar regions. This form of differential rotation, also observed in many other low-mass stars, is understood to arise when Coriolis effects are stronger than those associated with buoyant driving of the convection. When buoyancy dominates, a so-called antisolar state of differential rotation results, characterized by rapidly-rotating poles and a slow equator. The transition between these two states has been shown to occur when the intensity of these two forces is roughly equal or, equivalently, when the convective Rossby number of the system is unity. Here we consider an alternative view of the transition that relates this phenomenon to convective structure and convective-zone depth. Using a series of 3-D rotating convection-zone simulations, we demonstrate that the solar/antisolar transition occurs when the columnar convective structures characteristic of rotating convection attain a diameter roughly equivalent to the shell depth. When the characteristic convective wavelength exceeds twice the shell depth, we find that the coherent convective structures necessary to sustain an equatorward Reynolds stress are lost, and an antisolar state results. We conclude by presenting a force-balance analysis that relates this geometric interpretation of the transition to the convective-Rossby-number criteria identified in previous studies.

description: The conventional way of formulating inverse problems such as identification of a (possibly infinite dimensional) parameter, is via some forward operator, which is the concatenation of the observation operator with the parameter-to-state-map for the underlying model. Recently, all-at-once formulations have been considered as an alternative to this reduced formulation, avoiding the use of a parameter-to-state map, which would sometimes lead to too restrictive conditions. Here the model and the observation are considered simultaneously as one large system with the state and the parameter as unknowns. A still more general formulation of inverse problems, containing both the reduced and the all-at-once formulation, but also the well-known and highly versatile so-called variational approach (also called Kohn-Vogelius functional approach) as special cases, is to formulate the inverse problem as a minimization problem -- instead of an equation -- for the state and parameter. Regularization can be incorporated via imposing constraints and/or adding regularization terms to the objective. In this paper, after giving a motivation by formulating the electrical impedance tomography (EIT) problem by means of the classical Kohn-Vogelius functional, we will dwell on the regularization aspects for such variational formulations in an abstract setting. Indeed, combination of regularization by constraints and by penalization leads to new methods that are applicable without solving forward problems. In particular, for the EIT problem we will consider a method employing box constraints in a very natural manner to incorporate the discrepancy principle for regularization parameter choice as well as a priori information on the searched for conductivity.

Using analytical results along with numerical simulation of the model, we show that the above evolutionary model results in weighted scale free networks. Indeed we find that in the one mode picture we have weighted networks with scale free distributions for interesting quantities like the weights, the degrees and the weighted degrees of the nodes and the weights of the edges.

title: Male Earnings Dispersion Over the Period 1973 to 1995 in Four Industries
Creators: name: Taylor, Karl
Publisher: name: The Open University
Year: 1999

description: The following looks at developments in male earnings dispersion in four UK industries over the period 1973 to 1995. Evidence to date in the UK is largely based at the economy-wide level only, or aggregated into manufacturing and non manufacturing sectors. By considering industries other than solely manufacturing it is possible that different trends have occurred in earnings dispersion for each industry. The main objective is to firstly split earnings dispersion over the 23 years into two components: between-group earnings dispersion which occurs as a result of differing worker characteristics across the population; and within-group earnings dispersion, that is any remaining dispersion after controlling for measurable worker characteristics. And secondly, potential factors able to explain within-group earnings dispersion in each industry are tested, namely technological change; globalisation; female participation; immigration and institutional change. The empirical methodology is two step in nature. Initially, micro data based upon the individual is used to purge dispersion of human capital and personal influences. Then, time series techniques are employed to analyse the trend in the measure of within-group dispersion and the potential causal factors. The results from the first step indicate that whilst within-group earnings dispersion dominates between-group earnings dispersion trends differed across each industry. In line with previous results at the aggregate level, it appears that relative demand shifted in favour of the higher skill endowed. The second stage results indicate that whilst technological shocks are significant in each industry, other factors have a role to play in particular globalisation and supply side influences. A time series analysis of the explainable part of the earnings distribution i.e. between-group earnings dispersion shows that this too was influenced by market forces and institutional change. Furthermore, the returns to education were influenced by technological change and globalisation.

description: In this Letter, properties of black hole (BH) mass are well checked for the interesting object SDSS J0159, a changing-look AGN and also a host galaxy of a tidal disruption event (TDE). Through spectral absorption features, the stellar velocity dispersion of SDSS J0159 can be well measured as $σ\sim81~{\rm km/s}$, leading to SDSS J0159 being an apparent outlier in the \msig space, because of the BH mass estimated through the \msig relation about two magnitudes lower than the reported virial BH mass of about $10^8~{\rm M_\odot}$. After considerations of contributions of stellar debris from the central TDE to broad line emission clouds, the over-estimated virial BH mass could be well explained in SDSS J0159. Therefore, over-estimated virial BH masses through broad line properties in the \msig space could be treated as interesting clues to support central TDEs.

description: Genetic diversity (GD) in populations is important in determining the adaptive potential of populations and is thus thought to influence whether populations decrease or increase in abundance. Yet, a robust evaluation of this premise is needed. By integrating data of 1,636 observations from 589 studies globally, we evaluated the relative GD (measured as log response ratio of expected heterozygosity, lnRR) of endangered and invasive plant species compared to control (common or native) species. We also evaluated the variables that influence the variation in population GD within each plant group. Results suggest that the decline in GD is lagging behind the population decline of most endangered plants and that a lower GD did not limit the population expansion of most invasive plants. The effect of inbreeding and gene flow on the relative GD of invasive species was mediated by population size, whereas gene flow directly but nonlinear impacted that of endangered plants, and inbreeding influenced it through an indirect pattern. Mating system was the most important life-history and ecological characteristic to drive relative GD of both endangered plants and invasive plants. The relative GD of endangered plants was also influenced by life form, distribution and rarity form. Overall, genetic diversity was not found to determine species status (endangered or invasive), but species characteristics and genetic factors do have a clear influence on species’ evolutionary potential. Understanding the factors that influence GD is key to prioritize management actions on endangered and invasive plants with low and high GD, respectively.

description: We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing binary (stars Aa and Ab) eclipses the star in the outermost orbit (star C), and (ii) these outer 4th body eclipses last for $\sim$12 days, the longest of any such system known. The three orbital periods are $\sim$3.3 days, $\sim$51 days, and $\sim$2100 days. The extremely long duration of the outer eclipses is due to the fact that star B slows binary A down on the sky relative to star C. We combine TESS photometric data, ground-based photometric observations, eclipse timing points, radial velocity measurements, the composite spectral energy distribution, and stellar isochones in a spectro-photodynamical analysis to deduce all of the basic properties of the four stars (mass, radius, $T_{\rm eff}$, and age), as well as the orbital parameters for all three orbits. The four masses are $M_{\rm Aa} =0.382$M$_\odot$, $M_{\rm Ab} =0.300$M$_\odot$, $M_{\rm B} =0.540$M$_\odot$ and $M_{\rm C} =0.615$M$_\odot$, with a typical uncertainty of 0.015 M$_\odot$.

Boolean Coverings of Quantum Observable Structure: A Setting for an Abstract Differential Geometric Mechanism
Creators: name: Zafiris, Elias
Publisher: name: arXiv
Year: 2003
Subjects: subject: Mathematical Physics (math-ph)

description: We develop the idea of employing localization systems of Boolean coverings, associated with measurement situations, in order to comprehend structures of Quantum Observables. In this manner, Boolean domain observables constitute structure sheaves of coordinatization coefficients in the attempt to probe the Quantum world. Interpretational aspects of the proposed scheme are discussed with respect to a functorial formulation of information exchange, as well as, quantum logical considerations. Finally, the sheaf theoretical construction suggests an opearationally intuitive method to develop differential geometric concepts in the quantum regime.

description: The momentum distribution of Lambda^0 hyperons produced from the quark-gluon plasma (QGP) in ultra-relativistic heavy-ion collisions is calculated in dependence on their polarization. The momentum distribution of Lambda^0 hyperons is defined by matrix elements of relativistic quark Wigner operators, which are calculated within the Effective quark model with chiral U(3)xU(3) symmetry and the Quark-Gluon transport theory. We show that the polarization of the Lambda^0 hyperon depends of the spin of the strange quark that agrees well with the DeGrand-Miettinen model. We show that Lambda^0 hyperons, produced from the QGP, are fully unpolarized. This means that a detection of unpolarized Lambda^0 hyperons, produced in ultra-relativistic heavy-ion collisions, should serve as one of the signatures for the existence of the QGP in intermediate states of ultra-relativistic heavy-ion collisions.

Orbital Ordering and Orbital Fluctuations in Transition Metal Oxides
Creators: name: Oles, Andrzej M.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We summarize some characteristic features of the frustrated magnetic interactions in spin-orbital models adequate for cubic transition metal oxides with orbital degeneracy. A generic tendency towards dimerization, found already in the degenerate Hubbard model, is confirmed for $t_{2g}$ but not for $e_g$ systems. In the $t_{2g}$ case the quantum orbital fluctuations are more pronounced and contribute to a stronger competition between different magnetic and orbital states. Therefore the orbital liquid states exist in some undoped $t_{2g}$ systems, while in the manganites such states can be triggered only by doping.

description: Through questionnaires and interviews, this paper surveyed and studied the sense of happiness of 187 left-behind elderly people in Guizhou. The results show that in the context of the rural labor transfer, the sense of happiness of left-behind elderly people is generally low. There are many influencing factors and complex causes. Through analysis, it is found that transfer of family labor has a great impact on the sense of happiness of left-behind elderly people. Finally, it came up with some pertinent recommendations for raising the sense of happiness of left-behind elderly people.
Risk Analysis of Homecare Physiotherapist Work Posture in Stroke Patients with Arm Paralysis

Year: 2020
Subjects: Health Care

description: This study will examine to the extent of the homecare-service physiotherapist workload applies the task. This workload can be both physical and mentally which the first could bring greater burden than the latter one. In this discussion, the physical workload will be very much influenced by how good work the methods used or work postures to avoid the risk of illness due to incorrect work methods. The methodology in this study was using observation on the first stage. An observation to the working methods of physiotherapist was done to measure and observe the work posture of physiotherapist. Processing on work position data using REBA was then processed by calculating REBA scores from the working position of the arm therapy. Based on the ergonomic analysis that has been done on work postures, the risk of musculoskletal fatigue can be concluded that the physiotherapist needs to be improved, especially at the level of effort and time requirements of the physiotherapist. Improvement of work posture is needed because the results of the calculation of REBA score show the current work posture has a level of risk.
Old and new ether-drift experiments: a sharp test for a preferred frame

description: Motivated by the critical remarks of several authors, we have re-analyzed the classical ether-drift experiments with the conclusion that the small observed deviations should not be neglected. In fact, within the framework of Lorentzian Relativity, they might indicate the existence of a preferred frame relatively to which the Earth is moving with a velocity v_earth\sim 200$ km/s (value projected in the plane of the interferometer). We have checked this idea by comparing with the modern ether-drift experiments, those where the observation of the fringe shifts is replaced by the difference Δνin the relative frequencies of two cavity-stabilized lasers, upon local rotations of the apparatus or under the Earth's rotation. It turns out that, even in this case, the most recent data are consistent with the same value of the Earth's velocity, once the vacuum within the cavities is considered a physical medium whose refractive index is fixed by General Relativity. We thus propose a sharp experimental test that can definitely resolve the issue. If the small deviations observed in the classical ether-drift experiments were not mere instrumental artifacts, by replacing the high vacuum in the resonating cavities with a dielectric gaseous medium (e.g. air), the typical measured Δν\sim 1 Hz should increase by orders of magnitude. This expectation is consistent with the characteristic modulation of a few kHz observed in the original experiment with He-Ne masers. However, if such enhancement would not be confirmed by new and more precise data, the existence of a preferred frame can be definitely ruled out.

description: Yiwan Economic Corridor is located in the core area of western Jiangxi Province. It is an important part of the middle reaches of the Yangtze River city clusters and the open cooperation pilot zone of Jiangxi and Hunan provinces. The construction of the Yiwan Economic Corridor is an important measure to implement the strategy of “revitalizing and strengthening cities through developing industries”. It is required to deepen the understanding in ideology, grasp the orientation in the thought, and properly deal with relationship in the promotion process. This paper evaluated the advantages and challenges in the construction of Yiwan Economic Corridor, and came up with some recommendations for development of Yiwan Economic Corridor.
