description: The development of social media has improved public discussion online. The proliferation of social media data provides easy access to a huge amount of user-generated content. Geotagged microblogs have been investigated in a variety of research fields for understanding spatial temporal pattern in subjects like human mobility and characteristics of a city. Besides geotagged microblogs, textual content can also be used to harvest geographical information. However, there is little research on this topic. Therefore, in this study, we aim to demonstrate how we can illustrate the connections between a virtual community and other states and regions by analysing microblogs. To fulfill the research aim, we present the workflow of how to define a virtual community and harvest geographical information from microblog feeds. Then we discuss the visualization techniques we need to display such information. In order to do so, Sina Weibo was picked as a data source to demonstrate the international connections between China and rest of the world. Through visual analysis, we find out that even in Cyberspace, the physical world still has an impact, and it can be proved that states geographically closer to China have a higher level of attention (stronger data flow). In the meantime, we can also notice the barrier of information exchange caused by real space distance has less influence in Cyberspace, a virtual community can have strong bound with faraway country. But generally speaking, the level of attention of a state is related to its economy power. And there is a different topic preference between male and female user. This study may provide a new research aspect for analysis human thought, the spread of news, international relations, cross-culture communication based on textual geoinformation contained in social media data.

description: Molecular dynamic simulations are used to study the heating of a gold nanorod of 2624 atoms. We show that roughening of surface {110} facets leads to a shape transformation and structural rearrangement of surface and bulk atoms in the rod, in order to reach a more stable configuration. Our results show that the stability of the nanorod is governed by the free energetics of the surface facets.

description: We describe a new, distance-independent method for calculating the magnetic activity strength in low mass dwarfs, L_{Hα}/L_{bol}. Using a well-observed sample of nearby stars and cool standards spanning spectral type M0.5 to L0, we compute ``χ'', the ratio between the continuum flux near H-alpha and the bolometric flux, f_{\lambda6560}/f_{bol}. This ratio may be multiplied by the measured equivalent width of the H-alpha emission line to yield L_{Hα}/L_{bol}. We provide χvalues for all objects in our sample, as well as fits to χas a function of color and average values by spectral type. This method was used by West et al.(2004) to examine trends in magnetic activity strength in low mass stars.

description: Entanglement properties of IBM Q 53 qubit quantum computer are carefully examined with the noisy intermediate-scale quantum (NISQ) technology. We study GHZ-like states with multiple qubits (N=2 to N=7) on IBM Rochester and compare their maximal violation values of Mermin polynomials with analytic results. A rule of N-qubits orthogonal measurements is taken to further justify the entanglement less than maximal values of local realism (LR). The orthogonality of measurements is another reliable criterion for entanglement except the maximal values of LR. Our results indicate that the entanglement of IBM 53-qubits is reasonably good when N <= 4 while for the longer entangle chains the entanglement is only valid for some special connectivity.

description: The recent discovery of an Earth-sized planet (TOI-700 d) in the habitable zone of an early-type M-dwarf by the Transiting Exoplanet Survey Satellite constitutes an important advance. In this Letter, we assess the feasibility of this planet to retain an atmosphere -- one of the chief ingredients for surface habitability -- over long timescales by employing state-of-the-art magnetohydrodynamic models to simulate the stellar wind and the associated rates of atmospheric escape. We take two major factors into consideration, namely, the planetary atmospheric composition and magnetic field. In all cases, we determine that the atmospheric ion escape rates are potentially a few orders of magnitude higher than the inner Solar system planets, but TOI-700 d is nevertheless capable of retaining a $1$ bar atmosphere over gigayear timescales for certain regions of the parameter space. The simulations show that the unmagnetized TOI-700 d with a 1 bar Earth-like atmosphere could be stripped away rather quickly ($

description: With the development of communication in embedded systems, machine to machine communication becomes more and more important. The number of devices connected to the internet is growing exponentially, and intelligent devices are reaching more application areas than before. This leads to a fast growing complexity in all networked systems. Demands on manufacturing are also growing. The ability to dynamically adapt a manufacturing system to current needs has become a requirement to stay competitive. However, traditional systems are designed top-down, with each component selected to fulfill its specific purpose. This makes dynamic system reconfiguration a very challenging task that is proportional to the complexity of the system. The Arrowhead Framework is a proposed solution to manage this complexity by using a service oriented architecture. In this work a distributed synchronous measurement system within the ARROWHEAD framework, using the wireless 6LoWPAN MULLE platform developed for this framework, is implemented. While the ARROWHEAD framework focuses on communication between devices, the main challenge remaining for a distributed measurement system is clock synchronization, especially with low-cost Internet of Things devices. Therefore the focus of this work is to analyze the unique challenges that arise from software based clock synchronization, to develop mathematical error models and to propose methods to compensate these errors. The implementation of this work is based on the PTP protocol, however all the findings can be applied directly to all software based synchronization protocols. Software only timestamping leads to undetectable jitter from network conflicts and interference from other processes. Additionally the available timestamping points lead to transmission delay asymmetry. It will be shown that, by understanding these errors in detail, software based clock synchronization can be greatly improved.

description: Excerpts from the report: Citrus growers in Florida in recent years have been concerned over the generally unsatisfactory prices received for grapefruit. Efforts are being made to increase sales through expanding present markets and developing new markets. One of the important new markets being explored is that for canned frozen grapefruit sections. The major objectives of the market test for frozen grapefruit sections were (1) to assist the citrus industry in determining whether commercial processing of the product would be feasible from the standpoint of consumer acceptance and demand, (2) to determine whether the new product represented an addition to total market for grapefruit, or merely substituted for other grapefruit products, and (3) to measure the efficiency of the promotional activities employed in the test--newspaper, radio, and television advertising, and demonstration or sampling of the product in stores .

Within the Schwinger boson formulation, we need two qumodes (quantum-mechanical oscillators) at each lattice site. We envision that it might be possible to reach the scaling regime of this model and observe asymptotic freedom on near-term photonic quantum devices in the coming decade.

description: Design sharing sites provide UI designers with a platform to share their works and also an opportunity to get inspiration from others' designs. To facilitate management and search of millions of UI design images, many design sharing sites adopt collaborative tagging systems by distributing the work of categorization to the community. However, designers often do not know how to properly tag one design image with compact textual description, resulting in unclear, incomplete, and inconsistent tags for uploaded examples which impede retrieval, according to our empirical study and interview with four professional designers. Based on a deep neural network, we introduce a novel approach for encoding both the visual and textual information to recover the missing tags for existing UI examples so that they can be more easily found by text queries. We achieve 82.72% accuracy in the tag prediction. Through a simulation test of 5 queries, our system on average returns hundreds more results than the default Dribbble search, leading to better relatedness, diversity and satisfaction.

description: The fermion determinant in an instanton background for a quark field of arbitrary mass is determined exactly using an efficient numerical method to evaluate the determinant of a partial wave radial differential operator. The bare sum over partial waves is divergent but can be renormalized in the minimal subtraction scheme using the result of WKB analysis of the large partial wave contribution. Previously, only a few leading terms in the extreme small and large mass limits were known for the corresponding effective action. Our approach works for any quark mass and interpolates smoothly between the analytically known small and large mass expansions.

description: We show that the discrete Painlevé II equation with starting value $a_{-1}=-1$ has a unique solution for which $-1 < a_n < 1$ for every $n \geq 0$. This solution corresponds to the Verblunsky coefficients of a family of orthogonal polynomials on the unit circle. This result was already proved for certain values of the parameter in the equation and recently a full proof was given by Duits and Holcomb. In the present paper we give a different proof that is based on an idea put forward by Tomas Lasic Latimer which uses orthogonal polynomials. We also give an upper bound for this special solution.

description: The reentrant superconductivity is the peculiar phenomenon observed in paramagnetic metal UTe$_2$ in magnetic field parallel to the hard magnetisation axis. It is difficult to explain it in terms of field dependent intensity of magnetic fluctuations like it is done for explanation of the formally similar phenomena in the ferromagnetic uranium superconductors URhGe, UCoGe. Extremely large initial slope of the upper critical field temperature dependence suggests that the phenomenon has the quasi-two-dimensional nature. Indeed, according to the recent band structure calculations by Yuanji Xu et al, Phys.Rev. Lett. {\bf 123}, 217002 (2019) the Fermi surface of UTe$_2$ consists of two types slightly corrugated cylinders.The theory of reentrant superconductivity in UTe$_2$ based on its quasi-two-dimensional structure is presented here.

description: Inspired by the possibility of high-scale supersymmetry breaking in the string landscape where the cosmological constant problem and the gauge hierarchy problem can be solved while the strong CP problem is still a challenge for naturalness, we propose a supersymmetric KSVZ axion model with an approximate universal intermediate-scale ($\sim 10^{11}$ GeV) supersymmetry breaking. To protect the global Peccei--Quinn (PQ) symmetry against quantum gravitational violation, we consider the gauged discrete $Z_N$ PQ symmetry. In our model the axion can be a cold dark matter candidate, and the intermediate supersymmetry breaking scale is directly related to the PQ symmetry breaking scale. Gauge coupling unification can be achieved at about $2.7\times 10^{16}$ GeV. The Higgs mass range is 130 GeV to 160 GeV. We briefly discuss other axion models with high-scale supersymmetry breaking where the stabilization of the axion solution is similar.

description: Increasing requirements in the US to blend higher volumes of advanced biofuels with gasoline has increased the importance of imports of sugarcane-based ethanol from Brazil. Using the residual supply approach we test for oligopsony power of US importers in importing ethanol from Brazil. The residual supply elasticity is found to be highly elastic and positive indicating a small degree of market power. The result implies that the US importers are operating as oligopsony with respect to ethanol imports from Brazil and further restricting ethanol imports would reduce welfare of US importers.
An experimental investigation of Newtonian and non-Newtonian spray interaction with a moving surface
Creators: name: Dressler, Daniel Mervin
Publisher: name: University of British Columbia
Year: 2010

description: As a logical extension of previous work conducted into viscoelastic atomization, initially motivated by the need to improve spray coating transfer efficiencies, an experimental investigation into the spray-surface interaction for a number of Newtonian and non-Newtonian substitute test liquids is presented. Three model elastic liquids of varying polymer molecular weight and three inelastic liquids of varying shear viscosity were sprayed upon a moving surface to isolate the effect of elasticity and shear viscosity, respectively, on spray impaction behavior In addition, two liquids exhibiting shear thinning behavior and an industrial top of rail liquid friction modifier, KELTRACK ®, for use in the railroad industry, were included in the spray tests. High-speed photography was used to examine the impingement of these liquids on the surface. Ligaments, formed as a consequence of a liquid’s viscoelasticity, were observed impacting the surface for 300K PEO, 1000K PEO, and KELTRACK. These ligaments were broadly classified into four groups, based on their structure. Splashing of elastic liquid ligaments and droplets led to filamentary structures being expelled from the droplet periphery, which were then carried away by the atomizing air jet, leading to reductions in transfer efficiency. The effect of increasing elasticity amongst the three varying molecular weight elastic solutions was shown to increase the splash threshold, a similar effect was noted with increasing shear viscosity. Attempts were made at quantifying a critical splash-deposition limit for all test liquids however due to imaging system limitations, no quantitative conclusions could be made. For KELTRACK, both droplets and ligaments spread and deposited on the rail surface upon impact, with no observed splash or rebound. Splash was only noted when droplets impinged directly on a previously deposited liquid film and even then, splashing was well contained. Thus, KELTRACK’s current rheological formulation proved to be very effective in ensuring high coating transfer efficiencies.
Higher twists in spin structure functions from a "constituent quark" point of view

description: We discuss the implications of a "constituent quark" structure of the nucleon for the leading (1/Q^2-) power corrections to the spin structure functions. Our basic assumption is the presence of quark-gluon correlations in the nucleon wave function, whose size, rho ~ 0.3 fm, is small compared to the nucleon radius, R (two-scale picture). We argue that in this picture the isovector twist-4 matrix element in the proton has a sizable negative value, M_N^2 |f_2^{u - d}| ~ rho^{-2}, while the twist-3 matrix elements are small, M_N^2 d_2 ~ R^{-2}. These findings are in agreement with the result of a QCD fit to the g_1 world data, including recent neutron data from HERMES and Jefferson Lab Hall A, which gives M_N^2 f_2^{u - d} = -0.28 +/- 0.08 GeV^2.

Inference of central nervous system input and its complexity for interactive arm movement

Publisher: name: University of British Columbia
Year: 2011

description: This dissertation demonstrates a new method for inferring a representation of the motor command, generated by the central nervous system for interactive point-to-point, movements. This new tool, the input, inference neural network or IINN, allows estimation of the complexity of the motor command. The IINN was applied to experimental data, gathered from 7 volunteer subjects who performed point-to-point, tasks while interacting with a specially constructed haptic robot. The motor plan inference demonstrates that, for the point-to-point movement tasks executed during experiments, the motor command can be projected onto a low-dimensional manifold. This dimension is estimated to be 4 or 5 and far less than the degrees of freedom available in the arm. It is hypothesized that subjects simplify the problem of adapting to changing environments by projecting the motor control problem onto a motor manifold of low dimension. Reducing the dimension of the movement, optimization problem through the development of a motor manifold can explain rapid adaptation to new motor tasks.

description: The Chilean agricultural sector presents management problems, which indirectly affect their competitiveness and profitability. The objective of this work is to analysis the implementation process of Chilean Standard 2909 in middle units of cherry production in Curicó Province, Region Del Maule. It was conducted in the municipality of Romeral, Maule Region, during the season 2010-2011. The results indicate that none production unit approved the pre-audit NCh 2909, achieving a general rate of 19% of accomplishment. Strategy and leadership, and management of financial and physical resources were those criteria more complex to implement. In conclusion, the level of initial reached compliance NCh 2909, shows the labeling error 'entrepreneur' to producers - decision makers. The implementation of the standard involves a transformation of the way we manage resources, which, since the certification of the NCh 2909 not considered a regular update, there is no guarantee that it will consolidate and endure over time.

description: Meridional circulation regulates the Sun's interior dynamics and magnetism. While it is well accepted that meridional flows are poleward at the Sun's surface, helioseismic observations have yet to provide a definitive answer for the depth at which those flows return to the equator, or the number of circulation cells in depth. Here, we explore the observability of multiple circulation cells stacked in radius. Specifically, we examine the seismic signature of several meridional flow profiles by convolving time-distance averaging kernels with mean flows obtained from a suite of 3D hydrodynamic simulations. At mid and high latitudes, we find that weak flow structures in the deep convection zone can be obscured by signals from the much stronger surface flows. This contamination of 1--2 m s$^{-1}$ is caused by extended side lobes in the averaging kernels, which produce a spurious equatorward signal with flow speeds that are one order of magnitude stronger than the original flow speeds in the simulations. At low latitudes, the flows in the deep layers of the simulations are stronger ($> 2$ m s$^{-1}$) and multiple cells across the convection zone can produce a sufficiently strong signal to survive the convolution process. Now that meridional flows can be measured over two decades of data, the uncertainties arising from convective noise have fallen to a level where they are comparable in magnitude to the systematic biases caused by non-local features in the averaging kernels. Hence, these systematic errors are beginning to influence current helioseismic deductions and need broader consideration.

description: This article analyzed the weight of land in the economic performance of the primary livestock production sector, using the policy analysis matrix (PAM). The financial cost of the assets immobilized with the land factor was considered through its opportunity cost (OC). The study considered four alternatives to measure the OC: (a) a unique value given by a low-risk interest rate; (b) differential value, using rent value for the land exploited in such regime and a low-risk interest rate for the land owned by the producer; (c) differential value, using the same average value of rent for the land exploited in the scheme and zero-rate for the rest of the land; (d) unique zero-rate value for the whole land. The results suggest that, in general, Uruguayan livestock producers do not consider a OC for the land when assessing the profitability of their activity. For them, the land is a long-term safe investment, devoid of risk. In order to capture the true rationality of the livestock producer it would be advisable to consider the OC only when the producer actually leases the land and pays a rent. In principle, for owned land, it would be better considering a zero rate OC.

description: Using the star cluster catalogs from the Hubble Space Telescope program Legacy ExtraGalactic UV survey (LEGUS) and 8 $μ$m images from the IRAC camera on the Spitzer Space Telescope for 5 galaxies within 5 Mpc, we investigate how the 8 $μ$m dust luminosity correlates with the stellar age on the 30--50 pc scale of star forming regions. We construct a sample of 97 regions centered at local peaks of 8 $μ$m emission, each containing one or more young star cluster candidates from the LEGUS catalogs. We find a tight anti-correlation with a Pearson correlation coefficient of $r=-0.84\pm0.05$ between the mass-normalized dust-only 8 $μ$m luminosity and the age of stellar clusters younger than 1 Gyr; the 8 $μ$m luminosity decreases with increasing age of the stellar population. Simple assumptions on a combination of stellar and dust emission models reproduce the observed trend. We also explore how the scatter of the observed trend depends on assumptions of stellar metallicity, PAH abundance, fraction of stellar light absorbed by dust, and instantaneous versus continuous star formation models. We find that variations in stellar metallicity have little effect on the scatter, while PAH abundance and the fraction of dust-absorbed light bracket the full range of the data. We also find that the trend is better explained by continuous star formation, rather than instantaneous burst models. We ascribe this result to the presence of multiple star clusters with different ages in many of the regions. Upper limits of the dust-only 8 $μ$m emission as a function of age are provided.

description: Using the general connection between the upper limit on the neutrino mass and the upper limits on certain types of non-Standard Model interaction that can generate loop corrections to the neutrino mass, we derive constraints on some non-Standard Model $d\to ue^-\barν$ interactions. When cast into limits on $n\to pe^-\barν$ coupling constants, our results yield constraints on scalar and tensor weak interactions improved by more than an order of magnitude over the current experimental limits. When combined with the existing limits, our results yield $|C_S/C_V|\alt 5\times 10^{-3}$, $|C'_S/C_V|\alt 5\times 10^{-3}$, $|C_T/C_A| \alt 1.2\times 10^{-2}$ and $|C'_T/C_A| \alt 1.2\times 10^{-2}$.

description: E-commerce, a type of trading that occurs at a high frequency on the Internet, requires guaranteeing the integrity, authentication and non-repudiation of messages through long distance. As current e-commerce schemes are vulnerable to computational attacks, quantum cryptography, ensuring information-theoretic security against adversary's repudiation and forgery, provides a solution to this problem. However, quantum solutions generally have much lower performance compared to classical ones. Besides, when considering imperfect devices, the performance of quantum schemes exhibits a significant decline. Here, for the first time, we demonstrate the whole e-commerce process of involving the signing of a contract and payment among three parties by proposing a quantum e-commerce scheme, which shows resistance of attacks from imperfect devices. Results show that with a maximum attenuation of 25 dB among participants, our scheme can achieve a signature rate of 0.82 times per second for an agreement size of approximately 0.428 megabit. This proposed scheme presents a promising solution for providing information-theoretic security for e-commerce.

description: The decrease of both the rolling speed of the inflaton and the sound speed of the curvature perturbations can amplify the curvature perturbations during inflation so as to generate a sizable amount of primordial black holes. In the ultraslow-roll inflation scenario, it has been found that the power spectrum of curvature perturbations has a $k^4$ growth. In this paper, we find that when the speed of sound decreases suddenly, the curvature perturbations becomes scale dependent in the infrared limit and the power spectrum of the curvature perturbation only has a $k^2$ growth. Furthermore, by studying the evolution of the power spectrum in the inflation model, in which both the sound speed of the curvature perturbations and the rolling speed of the inflaton are reduced, we find that the power spectrum is nearly scale invariant at the large scales to satisfy the constraint from the cosmic microwave background radiation observations, and at the same time can be enhanced at the small scales to result in an abundant formation of primordial black holes. In the cases of the simultaneous changes of the sound speed and the slow-roll parameter $η$ and the change of the sound speed preceding that of the slow-roll parameter $η$, the power spectrum can possess a $k^6$ growth under certain conditions, which is the steepest growth of the power spectrum reported so far.

description: A growing interest in agrarian issues has been identified on the international level since 2006. The main reason for this change in approach to agriculture is a rise in the world food prices and the limitation of economic and physical access to food (mainly for food net importing countries). Thus, the period between 2007 and 2011 is being called as the world food crisis. The main aim of the paper is to present adjustments in the domestic trade policy (especially in exports policy) related to the agricultural trade. The analysis covers also the impact of export duties/tax and other export restrictions which have been imposed on agricultural products and food as well as the consequences of rising food prices for the global and domestic welfare. / Synopsis. Od roku 2006 na forum międzynarodowym można zaobserwować wzrost zainteresowania kwestią rolną. Stało się to za sprawą m.in. gwałtownego wzrostu cen surowców rolnych na rynkach międzynarodowych, a tym samym ograniczenia ekonomicznego i fizycznego dostępu do żywności (głównie dla krajów importerów netto żywności). Dlatego też okres 2007-2011 zyskał miano światowego kryzysu żywnościowego. Celem artykułu jest nakreślenie problematyki zmian w polityce handlowej państw (zwłaszcza polityki eksportowej) odnoszącej się do handlowej wymiany produktów rolnych w kontekście zagrożeń dla bezpieczeństwa żywnościowego. W opracowaniu dokonano analizy wpływu cła/podatku eksportowego i innych ograniczeń w eksporcie na poziom cen rolnych oraz dobrobyt zarówno na poziome globalnym, jak i krajowym.

description: The paper presents an evaluation of the structural pensions programme influence on agrarian changes in Poland. The research took advantage of not published data from Agency for Restructuring and Modernisation of Agriculture which were compared to results of agricultural census from 2002 and 2010. The structural pensions programme was one of activities in the Rural Development Programmes RDP 2004-2006 and 2007-2013. As a result of analyses it was noticed that beneficiaries of structural pensions (75.8 thousand) were 4.8% of the total number of farms in the country. Within the frame of the programme, farmers gave back 718.9 thousand hectare of agricultural land (4.6% of the total), in that 49.3% for successors and 50.7% for extension of other farms. The average size of a farm transferred within the frames of pensions programme was higher than the mean size in the country. / Synopsis. W opracowaniu przedstawiono ocenę oddziaływania rent strukturalnych na przemiany agrarne. Badania przeprowadzono w oparciu o niepublikowane dane ARiMR, które porównano do wyników spisu rolnego z 2002 i 2010 r. Renty strukturalne stanowiły jedno z działań zawartych w PROW 2004-2006 oraz 2007-2013 r. W wyniku analizy stwierdzono, że beneficjenci rent strukturalnych pod względem liczebnym (75,8 tys.) stanowili 4,8% ogólnej liczby gospodarstw rolnych w kraju. W ramach programu rolnicy przekazali 718,9 tys. ha użytków rolnych (4,6%), w tym 49,3% dla następców oraz 50,7% na powiększenie innych gospodarstw rolnych. Średnia wielkość jednego gospodarstwa rolnego przekazywanego w ramach programu rent była wyższa niż średnia krajowa.

description: The influence of accession to the EU on the development of foreign trade in fruit, vegetables and their preserves in Poland is presented in the paper. The impact of larger exports and imports on the tendencies in production of fresh and processed horticultural products was also analysed as well as the influence of accession on the level of certain indices used to measure competitiveness at sector level. They were mainly the mutual relations of exports and imports and their contribution to the domestic production and supply of horticultural products. / Synopsis. W artykule przedstawiono zmiany eksportu i importu owoców, warzyw i ich przetworów w Polsce po przystąpieniu do UE, a także wpływ zwiększonych obrotów handlu zagranicznego na kształtowanie się tendencji w produkcji świeżych i przetworzonych produktów ogrodniczych. Analizie poddano też zmiany poziomu wybranych wskaźników zewnętrznej konkurencyjności sektora ogrodniczego. Wskaźniki te dotyczą głównie wzajemnych relacji eksportu i importu oraz udziału eksportu i importu w krajowej produkcji i podaży produktów ogrodniczych.
