description: Topological phases are exotic quantum phases which are lacking the characterization in terms of order parameters. In this paper, we develop a unified framework based on variational iPEPS for the quantitative study of both topological and conventional phase transitions through entanglement order parameters. To this end, we employ tensor networks with suitable physical and/or entanglement symmetries encoded, and allow for order parameters detecting the behavior of any of those symmetries, both physical and entanglement ones. First, this gives rise to entanglement-based order parameters for topological phases. These topological order parameters allow to quantitatively probe topological phase transitions and to identify their universal behavior. We apply our framework to the study of the Toric Code model in different magnetic fields, which in some cases maps to the (2+1)D Ising model. We identify 3D Ising critical exponents for the entire transition, consistent with those special cases and general belief. However, we moreover find an unknown critical exponent beta=0.021. We then apply our framework of entanglement order parameters to conventional phase transitions. We construct a novel type of disorder operator (or disorder parameter), which is non-zero in the disordered phase and measures the response of the wavefunction to a symmetry twist in the entanglement. We numerically evaluate this disorder operator for the (2+1)D transverse field Ising model, where we again recover a critical exponent hitherto unknown in the model, beta=0.024, consistent with the findings for the Toric Code. This shows that entanglement order parameters can provide additional means of characterizing the universal data both at topological and conventional phase transitions, and altogether demonstrates the power of this framework to identify the universal data underlying the transition.

description: Incorporating the business perspective into prioritizing technical debt is essential to contribute to decision making in industry. In this paper, we evolve and evaluate a business-driven approach for technical debt prioritization. The approach was evaluated during a five-month industrial case study with business and technical stakeholders' active participation. The results show that the approach contributed to aligning business criteria between the business and technical stakeholders. We also observed a downward trend in the amount of technical debt that affects high-value business assets. Moreover, we identified eight business factors that affect the decision making related to the prioritization of technical debt. The study results suggest that the proposed business-driven technical debt prioritization approach can help teams to focus their efforts on paying off the business' most relevant debt.

description: We present Lick line-index measurements of extragalactic globular clusters in seven early-type galaxies (NGC 1380, 2434, 3115, 3379, 3585, 5846, and 7192) with different morphological types (E-S0) located in field and group/cluster environments. High-quality spectra were taken with the FORS2 instrument at ESO's Very Large Telescope. About 50% of our data allow an age resolution dt/t ~ 0.3 and a metallicity resolution ~0.25-0.4 dex, depending on the absolute metallicity. Globular cluster candidates are selected from deep B, V, R, I, K FORS2/ISAAC photometry with 80-100% success rate inside one effective radius. Using combined optical/near-infrared colour-colour diagrams we present a method to efficiently reduce fore-/background contamination down to <10%. We find clear signs for bi-modality in the globular cluster colour distributions of NGC 1380, 3115, and 3585. The colour distributions of globular clusters in NGC 2434, 3379, 5846, and 7192 are consistent with a broad single-peak distribution. For the analysed globular cluster systems the slopes of projected radial surface density profiles, of the form Sigma(R) ~ R^-Gamma, vary between ~0.8 and 2.6. Using globular clusters as a tracer population we determine total dynamical masses of host galaxies out to large radii (~1.6 - 4.8 Reff). For the sample we find masses in the range ~8.8*10^10 Msolar up to ~1.2*10^12 Msolar. The line index data presented here will be used in accompanying papers of this series to derive ages, metallicities and abundance ratios. A compilation of currently available high-quality Lick index measurements for globular clusters in elliptical, lenticular, and late-type galaxies is provided and will serve to augment the current data set.

Subjects: SECS-P/02 Politica economica

description: In a model of repeated Cournot competition under complete information, I
show how the existence of a fringe of managerial firms affects the stability
of a cartel of strict profit-maximizing firms. There always exists a critical
dimension of the fringe that makes the cartel unstable, and this dimension is
non-monotone in the total number of Örms. By appropriately selecting the
dimension of the fringe, a policy maker can affect the equilibrium outcome.
As an example, I consider the case of a domestic authority that is contemplating whether to allow entry of a fringe of managerial foreign firms in the
domestic market to increase the competitive pressure, thereby enhancing
domestic welfare.

description: Motivated by searches for $0νββ$ decay in nuclear experiments and collider probes of lepton number violation at dimension $d\geq7$, we investigate the sensitivity to the $d=5$ Weinberg operator using the non-resonant signature $pp\to \ell^\pm \ell'^{\pm} j j$ at the LHC. We develop a prescription for the operator that is applicable in collisions and decays, and focus on the $\ell\ell'=μμ$ channel, which is beyond the reach of nuclear decays. For a Wilson coefficient $C^{μμ}_5=1$, scales as heavy as $Λ\sim 8.3~(11)$~TeV can be probed with $\mathcal{L}=300~{\rm fb}^{-1}~(3~{\rm ab}^{-1})$. This translates to an effective $μμ$ Majorana mass of $\vert m_{μμ}\vert\sim7.3~(5.4)$~GeV, and establishes a road map for testing the Weinberg operator at accelerators.

The deindustrialisation/tertiarisation hypothesis reconsidered: a subsystem application to the OECD7

Subjects: SECS-P/02 Politica economica

description: The diffusion of outsourcing, both national and international, and
vertical FDIs among manufacturing firms, along with the higher integra-
tion of business services in manufacturing, has recently led to question
the empirical evidence supporting the Deindustrialisation/Tertiarisation
(DT) hypothesis. Rather than a \real" phenomenon, it has been argued,
DT would be an \apparent" one, mainly due to the reorganization of
production across national and sectoral boundaries.
The empirical studies that have dealt with the topic so far have
not been able to effectively rule out such possibility, because of two
main limitations: the sectoral level of the analysis and/or the national
focus. In order to overcome them, the paper carries out an appreciative
investigation of the actual extent of the DT occurred in the OECD
area over the '80s and the '90s by moving from a sector to a subsystem
perspective, thus retaining both direct and indirect relations, and by
referring to a \pseudo-World" of 7 OECD countries, thus taking into
account the \global" dimension of the phenomenon.
The results strongly support the DT hypothesis: although the weight
of business sector services in the manufacturing subsystem increased,
acting as a counterbalancing tendency to the manufacturing decline,
subsystem shares significantly decreased, thus confirming DT as a more
fundamental trend of modern economies.

description: We estimate actuarially fair premium rates for yield and revenue insurance for Georgia and South Carolina peaches. The premium rates for both products decrease at a decreasing rate as the mean farm-level yield increases. In general, the premium rate for revenue insurance exceeds the premium rate for yield insurance for a given coverage level and expected yield. Although the revenue and yield insurance rates differ in a statistical sense, they do not appear to differ in an economic sense except at high coverage levels for growers with very high yields.
Input-output data and service outsourcing. A reply to Dietrich, McCarthy and Anagnostou
Creators: name: Vittucci Marzetti, Giuseppe

Subjects: SECS-P/02 Politica economica

description: In a recent paper, McCarthy and Anagnostou (2004, The impact
of outsourcing on the transaction costs and boundaries of manufacturing,
International Journal of Production Economics, 88, pp. 61-71)
use a decomposition approach put forward by Dietrich (1999, Explaining
economic restructuring: an input-output analysis of organisational
change in the European Union, International Review of Applied Economics,
13(2), pp. 219-40) to analyze the impact of contracting-out in
the UK manufacturing decline over the ’80s and the ’90s.
Dietrich claims that this decomposition can distinguish the part
of the manufacturing output decrease produced by the increased integration
of services in manufacturing from the one which is instead
produced by final demand-related changes.
This paper aims at critically examining Dietrich’s decomposition
approach and showing its flaws. In so doing, the paper also carefully
analyzes the changes outsourcing produces in input-output tables.
Thus, it might prove useful also in avoiding further mistakes in
using input-output analysis for studying outsourcing-related changes
in economic structure.

description: We present the first determination of the proper motion of the neutron star low mass X-ray binary {Cen X-4} measured from relative astrometry of the secondary star using optical images at different epochs. We determine the Galactic space velocity components of the system and find them to be significantly different from the mean values that characterize the kinematics of stars belonging to the halo, and the thin and the thick disc of the Galaxy. The high metallicity of the secondary star of the system rules out a halo origin and indicates that the system probably originated in the Galactic disc. A statistical analysis of the galactocentric motion revealed that this binary moves in a highly eccentric ($e\simeq 0.85\pm0.1$) orbit with an inclination of $\simeq 110^\circ$ to the Galactic plane. The large Galactic space velocity components strongly support that a high natal kick as a result of a supernova explosion could have propelled the system into such an orbit from a birth place in the Galactic disc. The high Li abundance in the secondary, comparable to that of stars in star forming regions and young stellar clusters like the Pleiades, may suggest a relatively recent formation of the system. Following the orbit backwards in time, we found that the system could have been in the inner regions of the Galactic disc $\sim$100--200 Myr ago. The neutron star might have formed at that moment. However, we cannot rule out the possibility that the system formed at a much earlier time if a Li production mechanism exists in this LMXB.

description: This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm trials for varietal evaluation and demonstration purposes.

description: In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemisphere of the Sun that occurred during the period 1996 to 2003. This period of investigation includes the ascending phase, the maximum and part of descending phase of solar cycle 23. It is revealed that the flare activity during this cycle is low compared to previous solar cycle, indicating the violation of Gnevyshev-Ohl rule. The distribution of flares with respect to heliographic latitudes shows a significant asymmetry between northern and southern hemisphere which is maximum during the minimum phase of the solar cycle. The present study indicates that the activity dominates the northern hemisphere in general during the rising phase of the cycle (1997-2000). The dominance of northern hemisphere is shifted towards the southern hemisphere after the solar maximum in 2000 and remained there in the successive years. Although the annual variations in the asymmetry time series during cycle 23 are quite different from cycle 22, they are comparable to cycle 21.

description: For a knot K in S^3, let T(K) be the characteristic toric sub-orbifold of the orbifold (S^3,K) as defined by Bonahon and Siebenmann. If K has unknotting number one, we show that an unknotting arc for K can always be found which is disjoint from T(K), unless either K is an EM-knot (of Eudave-Munoz) or (S^3,K) contains an EM-tangle after cutting along T(K). As a consequence, we describe exactly which large algebraic knots (ie algebraic in the sense of Conway and containing an essential Conway sphere) have unknotting number one and give a practical procedure for deciding this (as well as determining an unknotting crossing). Among the knots up to 11 crossings in Conway's table which are obviously large algebraic by virtue of their description in the Conway notation, we determine which have unknotting number one. Combined with the work of Ozsvath-Szabo, this determines the knots with 10 or fewer crossings that have unknotting number one. We show that an alternating, large algebraic knot with unknotting number one can always be unknotted in an alternating diagram. As part of the above work, we determine the hyperbolic knots in a solid torus which admit a non-integral, toroidal Dehn surgery. Finally, we show that having unknotting number one is invariant under mutation.

Subjects: SECS-P/01 Economia politica

description: This paper explores how cross-sectional data can be exploited jointly with
longitudinal data, in order to increase estimation effciency while properly tackling the potential bias due to unobserved individual characteristics. We propose
an innovative procedure and we show its implementation by analysing the determinants of consumption in Nicaragua, based on data from three Living Standard
Measurement Study surveys from 1993, 1998 and 2001. The last two rounds constitute an unbalanced longitudinal data set, while the first is a cross-section of
di®erent households. Under the assumption that the relationship between observed and unobserved characteristics is homogenous across time, information
from longitudinal is are used to clean the bias in the unpaired sample. In a second step, corrected unpaired observations are used jointly with panel data. This
reduces the standard errors of the estimation coe±cients and might increase their
significance as well, otherwise compromised by the limited variation provided by
the short longitudinal data.

description: We give a detailed study of axion-photon and photon-axion conversion amplitudes, which enter the analysis of ``light shining through a wall'' experiments. Several different calculational methods are employed and compared, and in all cases we retain a nonzero axion mass. To leading order, we find that when the photon frequency $ω$ is very close to the axion mass $m$, there is a threshold cusp which significantly enhances the photon to axion conversion amplitude, by a factor $ω/\sqrt{ω^2-m^2}$ relative to the corresponding axion to photon conversion process. When $m=0$, the enhancement factor reduces to unity and the results of previous calculations are recovered. Our calculations include an exact wave matching analysis, which shows how unitarity is maintained near threshold at $ω=m$, and a discussion of the case when the magnetic field extends into the ``wall'' region.

description: Planning - the ability to analyze the structure of a problem in the large and decompose it into interrelated subproblems - is a hallmark of human intelligence. While deep reinforcement learning (RL) has shown great promise for solving relatively straightforward control tasks, it remains an open problem how to best incorporate planning into existing deep RL paradigms to handle increasingly complex environments. One prominent framework, Model-Based RL, learns a world model and plans using step-by-step virtual rollouts. This type of world model quickly diverges from reality when the planning horizon increases, thus struggling at long-horizon planning. How can we learn world models that endow agents with the ability to do temporally extended reasoning? In this work, we propose to learn graph-structured world models composed of sparse, multi-step transitions. We devise a novel algorithm to learn latent landmarks that are scattered (in terms of reachability) across the goal space as the nodes on the graph. In this same graph, the edges are the reachability estimates distilled from Q-functions. On a variety of high-dimensional continuous control tasks ranging from robotic manipulation to navigation, we demonstrate that our method, named L3P, significantly outperforms prior work, and is oftentimes the only method capable of leveraging both the robustness of model-free RL and generalization of graph-search algorithms. We believe our work is an important step towards scalable planning in reinforcement learning.

description: This article provides an elementary introduction to Gaussian channels and their capacities. We review results on the classical, quantum, and entanglement assisted capacities and discuss related entropic quantities as well as additivity issues. Some of the known results are extended. In particular, it is shown that the quantum conditional entropy is maximized by Gaussian states and that some implications for additivity problems can be extended to the Gaussian setting.

Zinc phosphating on 6061-T6 aluminum alloy
Creators: name: Shi, Lei

description: There is an urgent need to develop new non-chromating coating methods for the corrosion protection of aluminum alloys, and this thesis reports studies to establish optimal working conditions for forming zinc phosphate coatings on 6061-T6 aluminum alloy. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and corrosion tests were used to characterize the treated 6061-A1 surface, and to assess the effects of different parameters in the coating bath, as well as different pre-treatments and post-treatments. The initial study investigated different working conditions for the zinc phosphating, and this built on other studies from this laboratory. An initially considered coating bath had 16.0 ml H3P04 (85%), 5.36 g ZnO and 0.5 g NaF per liter, and optimal conditions for coating involved dipping the 6061-A1 samples into this bath at 60 °C for 6 min. But the addition of more fluoride was shown to be effective for increasing the zinc phosphate coverage on the aluminum alloy; the optimal range of F" being from 400 ppm to 600 ppm for these conditions. Based on the working condition study, the effects of pre-treatments, posttreatments, and associated procedures involved with the zinc phosphating of 6061-A1 alloy on the quality of the final coating were investigated. Comparisons were made between acid etching and mechanical polishing in the pre-treatment stages, and the mechanical polishing involved was done by either machine polishing or hand polishing. New post-treatment procedures were investigated using methyltriethoxysilane. It results in a considerable increase in the zinc phosphate coverage and coating thickness on the aluminum surface. This gave a greatly improved corrosion resistance by the coating compared with samples that did not have the silane post-treatment. A related silane treatment can also be used at an intermediate stage in the zinc phosphating immersion. In order to improve the final coating, Cu²⁺ and Ni²⁺ ions were studied as accelerators. Cu(N0₃)₂ (0.002 wt%) and Ni(N0₃)₂ (0.0004 wt%) were separately introduced to the basic phosphating baths containing H₃PO₄; ZnO and NaF, and each was shown to not only increase the phosphating speed, but also to improve the corrosion resistance and adhesion, insofar as the coating contained smaller crystalline grains and increased coverage of zinc phosphate on the surface. Of these two accelerators, Ni²⁺ appeared especially effective at increasing the corrosion protection ability of the final coating. Although NO³⁻ has some capabilities as an accelerator it was shown that its effect was negligible in this context at the concentrations used.

description: Wyoming Game and Fish Department depredation payments were established to increase landowner tolerance toward, and this the supply of, certain types of wildlife. This study examined how socio-economic and demographic characteristics of farmers and ranchers in Wyoming relate to tolerance toward wildlife and depredation claim submission. The severity of depredation and landowner satisfaction with the depredation policy were evaluated. The financial stability and economic intent of farmers and ranchers significantly influenced tolerance toward wildlife. Landowners tended to be less tolerant of depredation ensuing from elk. The complexity of the submission process was a deterrent to damage claim submissions.

description: A survey of Kansas, Texas, and Iowa agricultural producers was taken to examine the factors affecting their grain marketing practices. Sales indices models and models of qualitative choice are used to determine whether marketers' choices of cash market, forward contract, or futures and options oriented marketing practices are significantly affected by their personal farm business characteristics. Results indicate that geographic location, farm size, grain enterprise specialization, farming experience, use of grain storage, and use of crop insurance have significant effects upon the respondents' choice of grain marketing practices.

description: In 1996, the USDA began reporting cattle-on-feed placements in various weight groups, which should provide information regarding expected slaughter timings and improve fed cattle price forecasts and marketing strategies. Private data were collected to obtain the necessary degrees of freedom to test statistical relationships between placement weight distributions, beef supply, and fed cattle prices. Use of placement weights improved beef supply forecasts only at a one-month horizon; it contributed nothing to price forecast accuracy or returns from selectively hedging.

description: For a period of more than six years the Research Division has had under observation the concrete pavement built without transverse joints on U.S. 31-W between Franklin and the Tennessee Line. The primary reason for observing performance year after year is to record the incidence of cracks and other more serious defects; but also the grooving of cracks in 1949 and the application of different joint sealing materials became an important part of the observations.
An insight on the Proof of Orientifold Planar Equivalence on the Lattice

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: In a recent paper, Armoni, Shifman and Veneziano (ASV) gave a formal non-perturbative proof of planar equivalence between the bosonic sectors of SU(N) super Yang-Mills theory and of a gauge theory with a massless quark in the antisymmetric two-indexes representation. In the case of three colors, the latter theory is nothing but one-flavor QCD. Numerical simulations are necessary to test the validity of that proof and to estimate the size of 1/N corrections. As a first step towards numerical simulations, I will give a lattice version of the ASV proof of orientifold planar equivalence in the strong-coupling and large-mass phase.

description: The impacts of using export taxes as a price control in a multi-market framework are explored using the cotton and yarn sectors in Pakistan as examples. Results show that the export tax on cotton increased domestic consumption and decreased exports of cotton in Pakistan, transferring income from cotton producers to yarn spinners and the government. There was a social loss to Pakistan in the cotton sector. The export tax on cotton increased domestic yarn production, consumption, exports, and incomes of yarn spinners, but resulted in a large transfer (social loss) out of the yarn sector.

description: The distributional behavior of futures price spreads is examined for four commodities: corn, live cattle, gold and T-bonds. Remarkably different results are found over commodities, time period, and sample size. Actual spread changes for the smaller sample size of gold and T-bonds and for corn produce more normal distributions for weekly than for daily differencing intervals, while all live cattle spreads for actual changes are normally distributed. However, the larger sample size of both gold and T-bonds and the relative spread changes for corn and live cattle do not become more normally distributed under temporal aggregation of the data.

description: We compare calculations based on the Dynamical Mean-Field Theory of the Hubbard model with the infrared spectral weight $W(Ω,T)$ of La$_{2-x}$Sr$_x$CuO$_4$ and other cuprates. Without using fitting parameters we show that most of the anomalies found in $W(Ω,T)$ with respect to normal metals, including the existence of two different energy scales for the doping- and the $T$-dependence of $W(Ω,T)$, can be ascribed to strong correlation effects.

Welfare Landscapes
history and theory of architecture
history and theory of unban design

description: There is no actor that influenced welfare landscape as much as the automobile. The car affected not only the urban form but also its perception. At the level of the urban form, new figures emerged such as the parking lot and the parking garage. Tools coming from the domain of semiotics and semiology were activated by architects to grasp this new reality and to make sense of it. Concerning the experi-ence of welfare landscapes, the car introduced a new rhythm, speed and regime of perception. This paper examines the ways in which the car, as a physical and perceptual presence, has influenced the design of welfare landscapes. Investigating cases from the UK, France, Italy, Sweden, and Norway the paper explores how architects and urban designers started taking the car into full consideration when designing new neighbourhoods and cities. Among the cases that are examined are the impact of the car on the work and thought of Alison and Peter Smithson in the UK, and the design of new towns in France such as the design for the the new city extension of Toulouse-Le Mirail by Georges Candilis, Alexis Josic, and Shadrach Woods. The emergence of a new understanding of the citizens’ sensibilities due to the generalised used of the car in the post-war society should be interpreted in relation to the welfare state. Alison Smithson’s concern, in AS in DS: An Eye on the Road, about the impact of mobility on our social patterns and social needs is interpreted in relation to the design strategies that emerged within the context of post-war welfare state. The Smithsons’ effort to address through their written work and their architectural and urban design practice the contrast between the new post-war society and the traditional one, is part of their aspiration to re-invent the role of architecture within a context that the civic aspect be-comes primordial. The Smithsons conceive the car as an important means within this endeavour of architecture to respond to the welfare values of the post-war society. Another example that is scruti-nized is the Järvalyftet in Sweden – a large-scale project that intended to renew a section of northern Stockholm with a population of ca. 60,000 – envisioned a renewed role for the motorways and their connection to housing design. Special attention is paid to the analysis of how the spaces for, and perceptions from the car can be considered as urban heritage – especially in an era in which automo-bilty is questioned.

description: Evaluations of the factors influencing the adoption of agricultural and natural resource management technologies among small farmers in developing countries have been mostly limited to qualitative discussions or simple descriptive statistics resulting in superficial and inconclusive findings. This study introduces the use of Poisson Count Regressions as a statistically appropriate procedure to analyze certain common types of adoption data. It uses them to assess the impact of key socio-economic, bio-physical, and institutional factors on the adoption of integrated pest management, agroforestry, and soil conservation technologies among small farmers in three Central American countries: Costa Rica, Panama, and El Salvador.
