description: We propose an efficient scheme for simulating the topological phases of matter based on silicon-vacancy (SiV) center arrays in phononic crystals. This phononic band gap structure allows for long-range spin-spin interactions with a tunable profile. Under a particular periodic microwave driving, the band-gap mediated spin-spin interaction can be further designed with the form of the Su-Schrieffer-Heeger (SSH) Hamiltonian. In momentum space, we investigate the topological characters of the SSH model, and show that the topological nontrivial phase can be obtained through modulating the periodic driving fields. Furthermore, we explore the zero-energy topological edge states at the boundary of the color center arrays, and study the robust quantum information transfer via the topological edge states. This setup provides a scalable and promising platform for studying topological quantum physics and quantum information processing with color centers and phononic crystals.

Correlated Hybrid Fluctuations from Inflation with Thermal Dissipation

description: We investigate the primordial scalar perturbations in the thermal dissipative inflation where the radiation component (thermal bath) persists and the density fluctuations are thermally originated. The perturbation generated in this model is hybrid, i.e. it consists of both adiabatic and isocurvature components. We calculate the fractional power ratio ($S$) and the correlation coefficient ($\cosΔ$) between the adiabatic and the isocurvature perturbations at the commencing of the radiation regime. Since the adiabatic/isocurvature decomposition of hybrid perturbations generally is gauge-dependent at super-horizon scales when there is substantial energy exchange between the inflaton and the thermal bath, we carefully perform a proper decomposition of the perturbations. We find that the adiabatic and the isocurvature perturbations are correlated, even though the fluctuations of the radiation component is considered uncorrelated with that of the inflaton. We also show that both $S$ and $\cos Δ$ depend mainly on the ratio between the dissipation coefficient $Γ$ and the Hubble parameter $H$ during inflation. The correlation is positive ($\cosΔ> 0$) for strong dissipation cases where $Γ/H >0.2$, and is negative for weak dissipation instances where $Γ/H <0.2$. Moreover, $S$ and $\cos Δ$ in this model are not independent of each other. The predicted relation between $S$ and $\cosΔ$ is consistent with the WMAP observation. Other testable predictions are also discussed.

description: A survey of 2,186 U.S. farmer, rancher, and fishery cooperatives ending their business year during calendar year 2013 showed a record business volume and net income before taxes. Gross business volume was $246 billion, while net business volume was $209 billion and net income before taxes totaled $6.2 billion. These cooperatives had almost $83 billion in assets, $48 billion of liabilities, and $35 billion in equity. Cooperatives were a major employer in rural areas, with 136,000 full-time workers and 55,000 part-time or seasonal employees. Business volume by commodity is reported for all cooperatives. Number of cooperatives, cooperative memberships, and number of employees are classified according to whether the business is a marketing, supply, or service cooperative. Trends in cooperative numbers, memberships, employees, business size, sales volume, net income, assets, liabilities, and net worth are reported.

description: We report the results of a new analysis of 13 wide band BeppoSAX observations of the BL Lac object Mkn 421. The data from LECS, MECS and PDS, covering an energy interval from 0.1 to over 100 keV, have been used to study the spectral variability of this source. We show that the energy distributions in different luminosity states can be fitted very well by a log-parabolic law F(E)=K*(E/E_1)^(-(a+b*Log(E/E_1))), which provides good estimates of the energy and flux of the synchrotron peak in the SED. In the first four short observations of 1997 Mkn 421 was characterized by a very stable spectral shape, with average values a=2.25 and b=0.45. In the observations of 1998 smaller values for both parameters, a~2.07 and b~0.34, were found and the peak energy in the SED was in the range 0.5-0.8 keV. Also in the observations of May 1999 and April-May 2000 the log-parabolic model gave a satisfactory description of the overall SED of Mkn 421. In particular, in the observations of spring 2000 the source was brighter than the other observations and showed a large change of the spectral curvature. Spectral parameters estimates gave a~1.8 and b~0.19 and the energy of the maximum in the SED moved to the range 1-5.5 keV. We give a possible interpretation of the log-parabolic spectral model in terms of particle acceleration mechanisms. An energy distribution of emitting particles with curvature close to the one observed can be explained by a simple model for statistical acceleration with the assumption that the probability for a particle to increase its energy is a decreasing function of the energy itself. A consequence of this mechanism is the existence of a linear relation between the spectral parameters a and b, well confirmed by the estimated values of these two parameters for Mkn421.(Abridged)

title: Land and Agrarian Reform in South Africa: Land Ownership, Land Markets and the State
Creators: name: Dolny, Helena
Publisher: name: The Open University
Year: 1993

description: This thesis deals with the role of land markets in the redistribution of land and agrarian reform in South Africa, a capitalist economy which is uniquely marked by the legacy of institutionalised racism and in which the land question is intimately bound up with both reparation and liberation. The first chapters provide the political, historical, and theoretical context. I examine the evolution of diverse, racially separated tenure systems, some marketable, others not. I review Classical, Marxist, and neoclassical theory of land and rents and methods of calculating the productive value which may diverge from the market price of land. A comparison of international compensation practice in land reforms separates the issue of price to the outgoing land owner from that of affordability to the beneficiaries. An analysis of agricultural restructuring and class stratification in white commercial farming and the black rural areas draws attention to the influential role of the state. A lack of economic or ecological sustainability is evident. A discussion of scale and productivity concludes that there are widely differing production functions affected by racial access to capital and skills and also by the communal inheritance of land use. It is impossible to identify an average rate of profit as pertains in neoclassical discussions on land prices. The commercial land market is unstable and influenced by the political climate as well as fiscal policies. I conclude that effective land redistribution depends on the strength of political organisation. The state's role is to facilitate an enduring process of land reform through a conducive legal and economic framework. This must accommodate various categories of beneficiaries providing differing conditions of access. Neither a unitary free land market nor its opposite, nationalisation, can respond effectively to redistributive demands and social needs. Diverse land ownership systems should continue in parallel: a non-marketable component for the marginalised, conditional subsidised access to marketable land and the "open" market for entrepreneurs would continue with measures to promote redistribution. Tenure flexibility responds to social demands and can enhance land use; new forms which promote democratic management should be promoted. While petty commodity producers can improve their productive base through cooperation these will not succeed without democratic management and state support.
Quantifying Voter Biases in Online Platforms: An Instrumental Variable Approach

description: In content-based online platforms, use of aggregate user feedback (say, the sum of votes) is commonplace as the "gold standard" for measuring content quality. Use of vote aggregates, however, is at odds with the existing empirical literature, which suggests that voters are susceptible to different biases -- reputation (e.g., of the poster), social influence (e.g., votes thus far), and position (e.g., answer position). Our goal is to quantify, in an observational setting, the degree of these biases in online platforms. Specifically, what are the causal effects of different impression signals -- such as the reputation of the contributing user, aggregate vote thus far, and position of content -- on a participant's vote on content? We adopt an instrumental variable (IV) framework to answer this question. We identify a set of candidate instruments, carefully analyze their validity, and then use the valid instruments to reveal the effects of the impression signals on votes. Our empirical study using log data from Stack Exchange websites shows that the bias estimates from our IV approach differ from the bias estimates from the ordinary least squares (OLS) method. In particular, OLS underestimates reputation bias (1.6--2.2x for gold badges) and position bias (up to 1.9x for the initial position) and overestimates social influence bias (1.8--2.3x for initial votes). The implications of our work include: redesigning user interface to avoid voter biases; making changes to platforms' policy to mitigate voter biases; detecting other forms of biases in online platforms.

description: OBJECTIVES: Traffic speed is important to public health as it is a major contributory factor to collision risk and casualty severity. 20mph (32km/h) speed limit interventions are an increasingly common approach to address this transport and health challenge, but a more developed evidence base is needed to understand their effects. This study describes the changes in traffic speed and traffic volume in the City of Edinburgh, pre- and 12 months post-implementation of phased city-wide 20mph speed limits from 2016-2018. METHODS: The City of Edinburgh Council collected speed and volume data across one full week (24 hours a day) pre- and post-20mph speed limits for 66 streets. The pre- and post-speed limit intervention data were compared using measures of central tendency, dispersion, and basic t-tests. The changes were assessed at different aggregations and evaluated for statistical significance (alpha = 0.05). A mixed effects model was used to model speed reduction, in the presence of key variables such as baseline traffic speed and time of day. RESULTS: City-wide, a statistically significant reduction in mean speed of 1.34mph (95% CI 0.95 to 1.72) was observed at 12 months post-implementation, representing a 5.7% reduction. Reductions in speed were observed throughout the day and across the week, and larger reductions in speed were observed on roads with higher initial speeds. Mean 7-day volume of traffic was found to be lower by 86 vehicles (95% CI: -112 to 286) representing a reduction of 2.4% across the city of Edinburgh (p = 0.39) but with the direction of effect uncertain. CONCLUSIONS: The implementation of the city-wide 20mph speed limit intervention was associated with meaningful reductions in traffic speeds but not volume. The reduction observed in road traffic speed may act as a mechanism to lessen the frequency and severity of collisions and casualties, increase road safety, and improve liveability.

The Star Formation Rate of the Universe at z~6 from the Hubble Ultra Deep Field

description: We determine the abundance of i'-band drop-outs in the recently-released HST/ACS Hubble Ultra Deep Field (UDF). Since the majority of these sources are likely to be z~6 galaxies whose flux decrement between the F775W i'-band and F850LP z'-band arises from Lyman-alpha absorption, the number of detected candidates provides a valuable upper limit to the unextincted star formation rate at this redshift. We demonstrate that the increased depth of UDF enables us to reach an 8-sigma limiting magnitude of z'(AB)=28.5 (equivalent to 1.5/h{70}^2 M_sun/yr at z=6, or 0.1 L*(UV) for the z~3 U-drop population), permitting us to address earlier ambiguities arising from the unobserved form of the luminosity function. We identify 54 galaxies (and only one star) at z'(AB)<28.5 with (i'-z')>1.3 over the deepest 11arcmin^2 portion of the UDF field. The characteristic luminosity (L*) is consistent with values observed at z~3. The faint end slope (alpha) is less well constrained, but is consistent with only modest evolution. The main change appears to be in the number density (Phi*). Specifically, and regardless of possible contamination from cool stars and lower redshift sources, the UDF data support our previous result that the star formation rate at z~6 was at least x6 LESS than at z~3 (Stanway, Bunker & McMahon 2003). This declining comoving star formation rate (0.005 h{70}M_sun/yr/Mpc^3 at z~6 for a Salpeter IMF) poses an interesting challenge for models which suggest that L>0.1L* star forming galaxies at z~6 reionized the universe. The short-fall in ionizing photons might be alleviated by galaxies fainter than our limit, or a radically different IMF. Alternatively, the bulk of reionization might have occurred at z>>6.

description: We study system design problems stated as parameterized stochastic programs with a chance-constraint set. We adopt a Bayesian approach that requires the computation of a posterior predictive integral which is usually intractable. In addition, for the problem to be a well-defined convex program, we must retain the convexity of the feasible set. Consequently, we propose a variational Bayes-based method to approximately compute the posterior predictive integral that ensures tractability and retains the convexity of the feasible set. Under certain regularity conditions, we also show that the solution set obtained using variational Bayes converges to the true solution set as the number of observations tends to infinity. We also provide bounds on the probability of qualifying a true infeasible point (with respect to the true constraints) as feasible under the VB approximation for a given number of samples.

description: Objective: Road traffic injuries (RTI) cause ∼1.2 million deaths and 50 million injuries annually, disproportionately occurring in low- and middle-income countries. Although policy changes and infrastructural developments have continued to contribute to the decrease in RTI-related deaths, limited studies have investigated the relationship between motorcycle taxi driver behaviors and RTIs in Rwanda. This study aims to describe the safety behaviors of commercial motorcyclists in Kigali, Rwanda. Methods: We surveyed 609 commercial motorcyclists in January 2014 then conducted a cross-sectional analysis of the results, including descriptive and bivariate logistic regression analyses. Results: We found that 38.7% of surveyed motorcycle drivers experienced a crash during their lifetime, of which, more than half (n = 134, 56.8%) suffered injuries. Of all injuries, 38.8% (n = 52) resulted in hospitalization, and 14.2% (n = 19) in disability. Among motorcyclists, 100% reported always wearing a helmet, 99% reported always wearing a chin strap, and 98.8% reported always having a passenger helmet. There was an association between sustaining a crash and believing that helmets (p = 0.08) and chin straps (p = 0.05) reduced crash risk. Conclusions: Rwandan commercial motorcyclists demonstrate generally proper safety behaviors, but remain a high-risk occupational group. Road safety policy initiatives have been effective in changing driver behavior regardless of driver safety beliefs.

Furthermore, we examine the existence of logarithmic corrections to the linear scaling of the gap with |J_perp|.

description: Infinite-dimensional Newton methods can be effectively used to derive numerical proofs of the existence of solutions to partial differential equations (PDEs). In computer-assisted proofs of PDEs, the original problem is transformed into the infinite Newton-type fixed point equation $w = - {\mathcal L}^{-1} {\mathcal F}(\hat{u}) + {\mathcal L}^{-1} {\mathcal G}(w)$, where ${\mathcal L}$ is a linearized operator, ${\mathcal F}(\hat{u})$ is a residual, and ${\mathcal G}(w)$ is a local Lipschitz term. Therefore, the estimations of $\| {\mathcal L}^{-1} {\mathcal F}(\hat{u}) \|$ and $\| {\mathcal L}^{-1}{\mathcal G}(w) \|$ play major roles in the verification procedures. In this paper, using a similar concept as the `Schur complement' for matrix problems, we represent the inverse operator ${\mathcal L}^{-1}$ as an infinite-dimensional operator matrix that can be decomposed into two parts, one finite dimensional and one infinite dimensional. This operator matrix yields a new effective realization of the infinite-dimensional Newton method, enabling a more efficient verification procedure compared with existing methods for the solution of elliptic PDEs. We present some numerical examples that confirm the usefulness of the proposed method. Related results obtained from the representation of the operator matrix as ${\mathcal L}^{-1}$ are presented in the appendix.

description: In this paper we consider the functional equation for alternating factorial sum and some of its particular solutions (alternating Kurepa's function $A(z)$ from [Petojevic_02] and function $A_{1}(z)$). We determine an extension of domain of functions $A(z)$ and $A_{1}(z)$ in the sense of the principal value at point [Slavic_73], [Mijajlovic & Malesevic_07]. Using the methods from [Slavic_73] and [Malesevic_03] we give a new representation of alternating Kurepa's function $A(z)$, which is an analog of Slavi\' c's representation of Kurepa's function $K(z)$ [Slavic_73], [Marichev_83]. Also, we consider some representations of functions $A(z)$ and $A_{1}(z)$ via incomplete gamma function and we consider differential transcendency of previous functions too.

description: We study the properties of superconducting electrical circuits, realizing cavity QED. In particular we explore the limit of strong coupling, low dissipation, and elevated temperatures relevant for current and future experiments. We concentrate on the cavity susceptibility as it can be directly experimentally addressed, i.e., as the impedance or the reflection coefficient of the cavity. To this end we investigate the dissipative Jaynes-Cummings model in the strong coupling regime at high temperatures. The dynamics is investigated within the Bloch-Redfield formalism. At low temperatures, when only the few lowest levels are occupied the susceptibility can be presented as a sum of contributions from independent level-to-level transitions. This corresponds to the secular (random phase) approximation in the Bloch-Redfield formalism. At temperatures comparable to and higher than the oscillator frequency, many transitions become important and a multiple-peak structure appears. We show that in this regime the secular approximation breaks down, as soon as the peaks start to overlap. In other words, the susceptibility is no longer a sum of contributions from independent transitions. We treat the dynamics of the system numerically by exact diagonalization of the Hamiltonian of the qubit plus up to 200 states of the oscillator. We compare the results obtained with and without the secular approximation and find a qualitative discrepancy already at moderate temperatures.

Self-gravitating global monopole and nonsingular cosmology

description: We review some recent results concerning the properties of a spherically symmetric global monopole in $(D=d+2)$-dimensional general relativity. Some common features of monopole solutions are found independently of the choice of the symmetry-breaking potential. Thus, the solutions show six types of qualitative behavior and can contain at most one simple horizon. For the standard Mexican hat potential, we analytically find the $D$-dependent range of $γ$ (the gravitational field strength parameter) in which there exist globally regular solutions with a monotonically growing Higgs field, containing a horizon and a Kantowski-Sachs (KS) cosmology outside it, where the topology of spatial sections is $\R\times §^d$. Their cosmological properties favor the idea that the standard Big Bang might be replaced with a nonsingular static core and a horizon appearing as a result of some symmetry-breaking phase transition on the Planck energy scale. We have also found families of new solutions with an oscillating Higgs field, parametrized by the number of its knots. All such solutions describe space-times of finite size, possessing a regular center, a horizon and a singularity beyond it.

On secure communication in sensor networks under q-composite key predistribution with unreliable links
Creators: name: Zhao, Jun
Publisher: name: arXiv
Year: 2019
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Many applications of wireless sensor networks (WSNs) require deploying sensors in hostile environments, where an adversary may eavesdrop communications. To secure communications in WSNs, the q-composite key predistribution scheme has been proposed in the literature. In this paper, we investigate secure k-connectivity in WSNs operating under the q-composite scheme, in consideration of the unreliability of wireless links. Secure k-connectivity ensures that any two sensors can find a path in between for secure communication, even when k - 1 sensors fail. We present conditions on how to set the network parameters such that the network has secure k-connectivity asymptotically almost surely. The result is given in the form of a sharp zero-one law.

description: Gravitational-wave detectors on earth have detected gravitational waves from merging compact objects in the local Universe. In future we will detect gravitational waves from higher-redshift sources, which trace the high-redshift structure formation history. That is, by observing high-redshift gravitational-wave events we will be able to probe structure formation history. This will provide additional insight into the early Universe when primordial fluctuations are generated and also into the nature of dark matter.

description: As part of a feasibility study, this paper shows the NASA Valkyrie humanoid robot performing an end-to-end improvised explosive device (IED) response task. To demonstrate and evaluate robot capabilities, sub-tasks highlight different locomotion, manipulation, and perception requirements: traversing uneven terrain, passing through a narrow passageway, opening a car door, retrieving a suspected IED, and securing the IED in a total containment vessel (TCV). For each sub-task, a description of the technical approach and the hidden challenges that were overcome during development are presented. The discussion of results, which explicitly includes existing limitations, is aimed at motivating continued research and development to enable practical deployment of humanoid robots for IED response. For instance, the data shows that operator pauses contribute to 50\% of the total completion time, which implies that further work is needed on user interfaces for increasing task completion efficiency.

description: Background and Objectives Administration of diclofenac may lead to immune haemolytic anaemia (IHA) owing to the presence of drug-dependent antibodies and/or autoantibodies. A relationship with oral or intramuscular drug administration is unknown. Here, we describe a patient who apparently tolerated oral diclofenac but developed severe IHA following intramuscular injection of the drug. Patients and Methods A 66-year-old-female was admitted to hospital because of jaundice and nausea, which were initially presumed to be manifestations of a postcholecystectomy syndrome. The patient soon developed haemolysis and renal failure. Although the symptoms and signs were suggestive of autoimmune haemolytic anaemia (AIHA), the patient had diclofenac-induced IHA. Results Serological testing, including detection of drug-dependent antibodies, was performed using standard techniques. The patient's serum was found to contain a highly reactive diclofenac-dependent red cell antibody of the immune complex type (titre 256 000). She recovered after 7 weeks of treatment with prednisolone, blood transfusions, haemodialysis and plasma exchange. Conclusions Diclofenac-induced IHA should always be considered when a patient on diclofenac develops haemolysis.
Periodic orbit theory for the Hénon-Heiles system in the continuum region

description: We investigate the resonance spectrum of the Hénon-Heiles potential up to twice the barrier energy. The quantum spectrum is obtained by the method of complex coordinate rotation. We use periodic orbit theory to approximate the oscillating part of the resonance spectrum semiclassically and Strutinsky smoothing to obtain its smooth part. Although the system in this energy range is almost chaotic, it still contains stable periodic orbits. Using Gutzwiller's trace formula, complemented by a uniform approximation for a codimension-two bifurcation scenario, we are able to reproduce the coarse-grained quantum-mechanical density of states very accurately, including only a few stable and unstable orbits.

description: A quantitative study of the field-induced magnetic ordering in TlCuCl$_3$ in terms of a Bose-Einstein condensation (BEC) of magnons is presented. It is shown that the hitherto proposed simple BEC scenario is in quantitative and qualitative disagreement with experiment. It is further shown that even very small Dzyaloshinsky-Moriya interactions or a staggered $g$ tensor component of a certain type can change the BEC picture qualitatively. Such terms lead to a nonzero condensate density for all temperatures and a gapped quasiparticle spectrum. Including this type of interaction allows us to obtain good agreement with experimental data.

description: This directory contains a listing, by State, of almost 1,500 farmer-owned marketing, supply, service, fishery, and bargaining cooperatives. The information was collected from every farmer, rancher, and fishery cooperative that USDA Rural Development’s Cooperative Programs surveyed and that gave permission to be listed in this directory. The information includes the cooperative’s contact information, type of cooperative, and products that they sell. This directory is updated on a regular basis on our Web page http://www.rd.usda.gov/programs-services/allprograms/ cooperative-programs. Cooperatives are classified according to type. Most are marketing, supply, service, bargaining, or a combination. Marketing cooperatives assemble and market commodities produced mostly by their farmer-members and may or may not engage in processing. Supply cooperatives purchase and/or manufacture farm production supplies for distribution, mostly to farmer or rancher-members. Service cooperatives perform a range of farm production and managementrelated services, such as grove care, agronomic services, financial and management consulting, artificial insemination and herd management, transportation, and storage. Bargaining cooperatives negotiate price, quality, and delivery terms with buyers on behalf of their members, but typically do not take title to commodities.
