description: We present results for lattice QCD with staggered fermions in the limit of infinite gauge coupling, obtained from a worm-type Monte Carlo algorithm on a discrete spatial lattice but with continuous Euclidean time. This is obtained by sending both the anisotropy parameter $ξ=a_σ/a_τ$ and the number of time-slices $N_τ$ to infinity, keeping the ratio $aT=ξ/Nτ$ fixed. The obvious gain is that no continuum extrapolation $N_τ\rightarrow \infty$ has to be carried out. Moreover, the algorithm is faster and the sign problem disappears. We derive the continuous time partition function and the corresponding Hamiltonian formulation. We compare our computations with those on discrete lattices and study both zero and finite temperature properties of lattice QCD in this regime.

description: This article integrates fuzzy set theory in Data Envelopment Analysis (DEA) framework to compute technical efficiency scores when input and output data are imprecise. The underlying assumption in convectional DEA is that inputs and outputs data are measured with precision. However, production agriculture takes place in an uncertain environment and, in some situations, input and output data may be imprecise. We present an approach of measuring efficiency when data is known to lie within specified intervals and empirically illustrate this approach using a group of 34 dairy producers in Pennsylvania. Compared to the convectional DEA scores that are point estimates, the computed fuzzy efficiency scores allow the decision maker to trace the performance of a decision-making unit at different possibility levels.

description: We study a topological string description of the c < 1 non-critical string whose matter part is defined by the time-like linear dilaton CFT. We show that the topologically twisted N=2 SL(2,R)/U(1) model (or supersymmetric 2D black hole) is equivalent to the c < 1 non-critical string compactified at a specific radius by comparing their physical spectra and correlation functions. We examine another equivalent description in the topological Landau-Ginzburg model and check that it reproduces the same scattering amplitudes. We also discuss its matrix model dual description.

Interlayer spin-singlet pairing induced by magnetic interactions in an antiferromagnetic superconductor
Creators: name: Shimahara, Hiroshi
Publisher: name: arXiv
Year: 2004
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: It is shown that interlayer spin-singlet Cooper pairing is induced by magnetic interactions in a metallic antiferromagnet of stacked conductive layers in which each layer is ferromagnetically polarized and they order antiferromagnetically in stacking direction. As a result, the antiferromagnetic long-range order and superconductivity coexist at low temperatures. It is shown that T_AF > T_c except for in a very limited parameter region unless T_AF = 0, where T_AF and T_c denote the antiferromagnetic and superconducting transition temperatures, respectively. It is found that the exchange field caused by the spontaneous staggered magnetization does not affect superconductivity at all, even if it is very large. The resultant superconducting order parameter has a horizontal line node, and is isotropic in spin space in spite of the anisotropy of the background magnetic order. We discuss the possible relevance of the present mechanism to the antiferromagnetic heavy fermion superconductors UPd_2Al_3 and CePt_3Si.

description: This paper investigates the temperature dependence of quantum information scrambling in local systems with an energy gap, $m$, above the ground state. We study the speed and shape of growing Heisenberg operators as quantified by out-of-time-order correlators, with particular attention paid to so-called contour dependence, i.e. dependence on the way operators are distributed around the thermal circle. We report large scale tensor network numerics on a gapped chaotic spin chain down to temperatures comparable to the gap which show that the speed of operator growth is strongly contour dependent. The numerics also show a characteristic broadening of the operator wavefront at finite temperature $T$. To study the behavior at temperatures much below the gap, we perform a perturbative calculation in the paramagnetic phase of a 2+1D O($N$) non-linear sigma model, which is analytically tractable at large $N$. Using the ladder diagram technique, we find that operators spread at a speed $\sqrt{T/m}$ at low temperatures, $T\ll m$. In contrast to the numerical findings of spin chain, the large $N$ computation is insensitive to the contour dependence and does not show broadening of operator front. We discuss these results in the context of a recently proposed state-dependent bound on scrambling.

The process of nurses’ adoption of the electronic health record
Creators: name: Cox, Richard Anthony
Publisher: name: University of British Columbia
Year: 2009

description: The electronic health record (EHR) is being introduced on some nursing units. The process of nurses' adoption of the EHR into practice is not well understood. The purpose of this grounded theory study was to gain further understanding of this adoption process, to identify the factors that influenced the adoption process, and the factors that influenced the learning experience. Semi-structured audio taped interviews were conducted with six nurses representing some variation in their level of technology adoption and the level of technology of the unit where they worked. Using the constant comparative method of data analysis, data was collected and analyzed simultaneously. Memos were used to assist in the development of the stages and phases identified in the analysis process. Findings revealed a three-staged process that involved "getting started", "getting comfortable with the computer system", and "establishing a pattern". "Getting started" included the nurses' receiving EHR training. "Getting comfortable with the computer system" involved learning how to access and use the EHR. "Establishing a pattern" involved choosing how they would access patient information. Individual, technical, and organizational factors seemed to influence the adoption process. Individual factors included the nurses' age and role, their educational preparedness, and their motivation to use the EHR; technical factors included the nurse's computer skill level, their use of the pre-existing computer system, and the availability of the EHR program; and organization factors included the nursing units' general response to change, the availability of time to practice, the availability and nature of support, and the organization's method of communication and implementation of the EHR appeared to influence the adoption process. Training geared to the learner's level, their computer skill level, their level of fear and anxiety, their sense of information overload, and the make-up of the training class related to computer skill mix influenced the learning experience. Although there are limitations in the study because more depth and variation in sampling is needed, the findings can add to our understanding of the adoption process of the EHR and factors that influenced that process. These findings suggest implications for education, practice, administration and research.

description: We investigate course registration data of 18 semesters at a Korean University to portray the time evolution of students' positions in the network of fellow students. Apart from being a study of the social positions of students, the present work is also an example of how large-scale, time resolved, affiliation networks can be analyzed. For example we discuss the proper definitions of weights, and propose a redefined weighted clustering coefficient. Among other things, we find that the students enter the network at the center and are gradually diffusing towards the periphery. On the other hand, the ties to the classmates of the first semester (still present at the university) will, on average, become stronger as time progresses.

We apply this formalism to several examples, thus showing its potential as an elegant analytical tool for simulating quantum optics experiments. Furthermore, we also use it to prove that EPR steering is a necessary requirement to remotely prepare a Wigner-negative state.

description: We report the first result of a supernova search program designed to measure the evolution of the supernova rate with redshift. To make the comparison with local rates more significant we copied, as much as possible, the same computation recepies as for the measurements of local rates. Moreover, we exploited the multicolor images and the photometric redshift technique to characterize the galaxy sample and accurately estimate the detection efficiency. Combining our data with the recently published meaurements of the SN Ia rate at different redshifts, we derived the first, direct measurement of the core collapse supernova rate at z = 0.26 as r_cc = 1.45^{+0.55}{-0.45} h^2 SNu [h=H_0/75]. This is a factor three {+/- 50%)} larger than the local estimate. The increase for a look back time of "only" 2.8 Gyr is more rapid than predicted by most of the published models of the SN rate evolution. Core-collapse SN rates measure the death rate of massive star and, because of the short time scale of evolution, can be translated in a measurement of the ongoing SFR. Assuming a Salpeter IMF and the standard scenario for core-collapse progenitors we derived to an estimate of the star formation rate at redshift 3.1^{+1.1}{-1.0} 10^-2 h^3 M_sun yr^-1 Mpc^{-3} which compare very well with a recent estimate based on the measurement of the Halpha luminosity density at the same redshift.

description: Over the past three decades, the agricultural biotechnology sector has been characterized by rapid innovation, market consolidation, and a more exhaustive definition of property rights. The industry attributes consistently identified by the literature and important to this analysis include: (i) endogenous sunk costs in the form of expenditures on R&D; (ii) seed and agricultural chemical technologies that potentially act as complements within firms and substitutes across firms; and (iii) property rights governing plant and seed varieties that have become more clearly defined since the 1970s. This paper adds to the stylized facts of the agricultural biotechnology industry to include the ability of firms to license technology, a phenomenon observed only recently in the market as licensing was previously precluded by high transactions costs and “anti-stacking” provisions. We extend Sutton's theoretical framework of endogenous sunk costs and market structure to incorporate the ability of firms to license technology under well-defined property rights, an observed characteristic not captured in previous analyses of the sector. Our model implies that technology licensing leads to lower levels of industry concentration then what would be found under Sutton's model, but that industry concentration remains bounded away from perfect competition as market size becomes large.

description: We have investigated the electronic structure and magnetic properties of GdN as a function of unit cell volume. Based on the first-principles calculations of GdN, we observe that there is a transformation in conduction properties associated with the volume increase: first from halfmetallic to semi-metallic, then ultimately to semiconducting. We show that applying stress can alter the carrier concentration as well as mobility of the holes and electrons in the majority spin channel. In addition, we found that the exchange parameters depend strongly on lattice constant, thus the Curie temperature of this system can be enhanced by applying stress or doping impurities.

description: We investigate the relation between the number of passes made by a football team and the number of goals. We analyze the 380 matches of a complete season of the Spanish national league "LaLiga" (2018/2019). We observe how the number of scored goals is positively correlated with the number of passes made by a team. In this way, teams on the top (bottom) of the ranking at the end of the season make more (less) passes than the rest of the teams. However, we observe a strong asymmetry when the analysis is made depending on the part of the match. Interestingly, fewer passes are made on the second part of a match while, at the same time, more goals are scored. This paradox appears in the majority of teams, and it is independent of the number of passes made. These results confirm that goals in the first part of matches are more "costly" in terms of passes than those scored on second halves.

description: 7Li NMR measurements on LiV2O4 from 0.5 to 4.2 K are reported. A small concentration of magnetic defects within the structure drastically changes the 7Li nuclear magnetization relaxation versus time from a pure exponential as in pure LiV2O4 to a stretched exponential, indicating glassy behavior of the magnetic defects. The stretched exponential function is described as arising from a distribution of 7Li nuclear spin-lattice relaxation rates and we present a model for the distribution in terms of the dynamics of the magnetic defects. Our results explain the origin of recent puzzling 7Li NMR literature data on LiV2O4 and our model is likely applicable to other glassy systems.

description: A cost-benefit analysis (CBA) of an investment in the protection of malleefowl and associated native vegetation in the Lachlan Catchment’s central-west yielded a benefit-cost ratio of 1.4. The CBA is based on project expenditures over the past four years coupled with benefit estimates from a recent Choice Modelling study in the Lachlan Catchment. The project targets the protection of malleefowl on private land which has not yet been surveyed but where the species is known to be present. The CBA is subject to significant uncertainty due to a lack of available data. Nonetheless, sensitivity analysis indicates that the BCR is consistently larger than unity, if marginal in some cases. This suggests that the project is a worthwhile investment at this early stage. Furthermore, greater gains may be achieved by addressing the numerous threats facing the species and its habitat. The increased cost of such an investment may be more than offset by the gains in benefits due to relatively conservative assumptions associated with the benefit calculations in the BCA.

Subjects: subject: Offshore Platform

description: Decades of oil and gas production in the North Sea have left immense traces. Almost invisible to society, one of the largest and most active industrialregions in Europe stretches across the entire North Sea. With the end of the era of fossil fuels, the enormous number of physical structures developed for the purpose of oil production is becoming obsolete. Decommissioned and disused drilling platforms will be gradually returned to land for dismantling over the coming decades, which will reveal the hidden world of the North Sea giants to the public. The heritage of the northern European oil nations is also returning with an immense potential for temporary or permanent conversion.The exploration of their visual, functional and spatial potential is the starting point of this thesis. A strategy of Adaptive Reuse will be presented, which deals with political, ecological, economic and socio-cultural issues. In the second part of this thesis, a case study will be developed using the example of the Norwegian concrete platform Statfjord B, built in 1981. A scenario of a long-term reuse of offshore platforms will be developed. The concrete structures built for an eternity have the potential to provide space for a new relevance through conversion. A new programme in the context of "Research, climate, environmental and marine protection" can contribute to compensate past decades of oil production. Last but not least, the impressive giants of the North Sea represent an enormous engineering achievement, which justifies it to be considered an industrial cultural heritage and worth preserving. This work attempts to underline the regional and global relevance of the North Sea as a historical trade and economic zone on the one hand, and to point out a hidden world of oil structures in the North Sea which holds enormous architectural potential for conversion. Adaptive Reuse is applied as a concept for preservation of industrial monuments.
Lagrangian complexity persists with multimodal flow forcing in poroelastic systems

description: We extend previous analyses of the origins of complex transport dynamics in poroelastic media to the case where the input transient signal at a boundary is generated by a multimodal spectrum. By adding harmonic and anharmonic modal frequencies as perturbations to a fundamental mode we examine how such multimodal signals affect the Lagrangian complexity of poroelastic flow. While the results apply to all poroelastic media (industrial, biological and geophysical), for concreteness we couch the discussion in terms of unpumped coastal groundwater systems having a discharge boundary forced by tides. Particular local regions of the conductivity field generate saddles that hold up and braid (mix) trajectories, resulting in unexpected behaviours of groundwater residence time distributions and topological mixing manifolds near the tidal boundary. While increasing spectral complexity can reduce the occurrence of periodic points, especially for anharmonic spectra with long characteristic periods, other signatures of Lagrangian complexity persist. The action of natural multimodal tidal signals on confined groundwater flow in heterogeneous aquifers can induce exotic flow topologies and mixing effects that are profoundly different to conventional concepts of groundwater discharge processes. Taken together, our results imply that increasing spectral complexity results in more complex Lagrangian structure in flows through poroelastic media.

description: We present the third edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 46,420 objects in the SDSS Third Data Release that have luminosities larger than M_i = -22 (in a cosmology with H_0 = 70 km/s/Mpc, Omega_M = 0.3, and Omega_Lambda = 0.7), have at least one emission line with FWHM larger than 1000 km/s or are unambiguously broad absorption line quasars, are fainter than i = 15.0, and have highly reliable redshifts. The area covered by the catalog is 4188 sq. deg. The quasar redshifts range from 0.08 to 5.41, with a median value of 1.47; the high-redshift sample includes 520 quasars at redshifts greater than four, of which 17 are at redshifts greater than five. For each object the catalog presents positions accurate to better than 0.2 arcsec. rms per coordinate, five-band (ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information on the morphology and selection method. The catalog also contains radio, near-infrared, and X-ray emission properties of the quasars, when available, from other large-area surveys. The calibrated digital spectra cover the wavelength region 3800--9200A at a spectral resolution about 2000; the spectra can be retrieved from the public database using the information provided in the catalog. A total of 44,221 objects in the catalog were discovered by the SDSS; 28,400 of the SDSS discoveries are reported here for the first time.

description: We obtain reliable $ππ$ scattering amplitudes consistent with experimental data, both at low and high energies, and fulfilling appropriate analyticity properties. We do this by first fitting experimental low energy ($s^{1/2}\leq1.42 {\rm GeV}$) phase shifts and inelasticities with expressions that incorporate analyticity and unitarity. In particular, for the S wave with isospin~0, we discuss in detail several sets of experimental data. This provides low energy partial wave amplitudes that summarize the known experimental information. Then, we impose Regge behaviour as follows from factorization and experimental data for the imaginary parts of the scattering amplitudes at higher energy, and check fulfillment of dispersion relations up to 0.925 GeV. This allows us to improve our fits. The ensuing $ππ$ scattering amplitudes are then shown to verify dispersion relations up to 1.42 GeV, as well as $s - t - u$ crossing sum rules and other consistency conditions. The improved parametrizations therefore provide a reliable representation of pion-pion amplitudes with which one can test chiral perturbation theory calculations, pionium decays, or use as input for CP-violating $K$ decays. In this respect, we find $[a_0^{(0)}-a_0^{(2)}]^2=(0.077\pm0.008) M^{-1}_π$ and $δ_0^{(0)}(m^2_K)-δ_0^{(2)}(m^2_K)=52.9\pm1.6^{\rm o}$.

description: In this paper, a mathematical negotiation mechanism is designed to minimize the negotiators' costs in a distributed procurement problem at two echelons of an automotive supply chain. The buyer's costs are procurement cost and shortage penalty in a one-period contract. On the other hand, the suppliers intend to solve a multi-period, multi-product production planning to minimize their costs. Such a mechanism provides an alignment among suppliers' production planning and order allocation, also supports the partnership with the valued suppliers by taking suppliers' capacities into account. Such a circumstance has been modeled via bi-level programming, in which the buyer acts as a leader, and the suppliers individually appear as followers in the lower level. To solve this nonlinear bi-level programming model, a hybrid algorithm by combining the particle swarm optimization (PSO) algorithm with a heuristic algorithm based on A search is proposed. The heuristic A algorithm is embedded to solve the mixed-integer nonlinear programming (MINLP) sub-problems for each supplier according to the received variable values determined by PSO system particles (buyer's request for quotations (RFQs)). The computational analyses have shown that the proposed hybrid algorithm called PSO-A outperforms PSO-SA and PSO-Greedy algorithms.

Does anybody give a dam? The importance of public awareness for urban water conservation during drought

description: Demand management has been of interest in dry climates such as Australia, Spain and the Western United States for decades. It is particularly important to understand policy options during drought conditions, as drought periods have a disproportionate effect on supply infrastructure decisions. While water‐conservation campaigns aimed at inducing voluntary consumption reductions are almost universally employed by water managers in times of supply constraint, voluntary measures are generally dismissed in the economics literature as ineffective. We argue that the robust positive correlation between dam levels and consumption after controlling for policy changes suggests that there is a significant component of voluntary conservation. Furthermore, omitting dam levels from regressions may bias estimated impacts of policy changes.
Protecting the Booroolong Frog in the Namoi Catchment: A Cost-Benefit Analysis

description: The Booroolong frog project in the Namoi Catchment represents an environmental investment to protect the species and around 10.7 kilometres of its habitat in the catchment. The project’s benefit-cost ratio (BCR) of 8.6 indicates that the benefits outweigh the costs by a significant margin. The measures introduced by landholders, at relatively low cost, should therefore result in a significant return on investment upon project completion in 10 years time. The benefits are estimated using a choice modelling study which was recently developed for the valuation of investment in natural resource management in the Namoi Catchment. As this is a largely ex ante cost-benefit analysis, the BCR is subject to uncertainty associated with assumptions which had to be made for some variables. However, sensitivity analysis indicates that the project benefits outweigh the costs by a significant margin even under conservative conditions.

description: Australian governments are committed to the expansion of marine protected areas (MPAs) in Australian waters and have already established over 200 MPAs. However, this policy direction has a range of costs and benefits for the community which have largely remained unquantified. One of the main benefits of establishing MPAs are the non use values that the community for the protection of marine biodiversity. This study uses a dichotomous choice contingent valuation format with follow-up open-ended willingness to pay question to estimate these non use values for the establishment of MPAs in South-west Marine Region of Australia. It was found that on average Australian households would be WTP $104 for the establishment of MPAs that cover 10% of the South-west Marine Region. Aggregating this mean WTP estimate to 50% of the population of Australian households gives an aggregate WTP of $400M. However, whether the establishment of MPAs in the South-west Marine Region is economically efficient requires a consideration of all the potential costs and benefits. Other relevant costs and benefits for inclusion in a benefit cost analysis would include those associated with displacement of commercial and non-commercial uses, additional planning, compliance and monitoring costs as well as any predicted increases in commercial and non-commercial use values. If the net costs of establishing MPA over 10% of the South-west Marine Region are less than $400M,then the non-use benefits of establishing MPAs would exceed the other net costs and it would be considered to be economically efficient and desirable from a community welfare perspective. Given the difficulties of estimating precise WTP values from dichotomous choice data, any BCA of MPAs in the South-west Marine Region, incorporating the results of this study, should undertake sensitivity testing that includes the range of values reported including dichotomous choice and openended means to determine the robustness of BCA results to variations in the welfare estimate.
Scaling of Fracture Strength in Disordered Quasi-Brittle Materials

description: This paper presents two main results. The first result indicates that in materials with broadly distributed microscopic heterogeneities, the fracture strength distribution corresponding to the peak load of the material response does not follow the commonly used Weibull and (modified) Gumbel distributions. Instead, a {\it lognormal} distribution describes more adequately the fracture strengths corresponding to the peak load of the response. Lognormal distribution arises naturally as a consequence of multiplicative nature of large number of random distributions representing the stress scale factors necessary to break the subsequent "primary" bond (by definition, an increase in applied stress is required to break a "primary" bond) leading up to the peak load. Numerical simulations based on two-dimensional triangular and diamond lattice topologies with increasing system sizes substantiate that a {\it lognormal} distribution represents an excellent fit for the fracture strength distribution at the peak load. The second significant result of the present study is that, in materials with broadly distributed microscopic heterogeneities, the mean fracture strength of the lattice system behaves as $μ_f = \frac{μ_f^\star}{(Log L)^ψ} + \frac{c}{L}$, and scales as $μ_f \approx \frac{1}{(Log L)^ψ}$ as the lattice system size, $L$, approaches infinity.
