description: Variational algorithms for strongly correlated chemical and materials systems are one of the most promising applications of near-term quantum computers. We present an extension to the variational quantum eigensolver that approximates the ground state of a system by solving a generalized eigenvalue problem in a subspace spanned by a collection of parametrized quantum states. This allows for the systematic improvement of a logical wavefunction ansatz without a significant increase in circuit complexity. To minimize the circuit complexity of this approach, we propose a strategy for efficiently measuring the Hamiltonian and overlap matrix elements between states parametrized by circuits that commute with the total particle number operator. We also propose a classical Monte Carlo scheme to estimate the uncertainty in the ground state energy caused by a finite number of measurements of the matrix elements. We explain how this Monte Carlo procedure can be extended to adaptively schedule the required measurements, reducing the number of circuit executions necessary for a given accuracy. We apply these ideas to two model strongly correlated systems, a square configuration of H$_4$ and the $π$-system of Hexatriene (C$_6$H$_8$).

description: Using the 2013 Agricultural Resource Management Survey (ARMS) and 2014 TOTAL survey data we find that nearly 30 percent of U.S. farm businesses have a succession plan and forty percent of the designated successors are family members. Twenty-one percent of ARMS farms indicate they will retire in 5 years and 38 percent of these farm businesses plan to turn over management and operation of their farm business but retain some ownership. Only 19 percent will sell and 15 percent will rent. The TOTAL survey also indicates that 36 percent of farms planning to retire in 5 years have succession plans and 30 percent will be sold to relatives and 58 percent is planned to be transferred by some form of legal transfer.

description: We report the results of a study of multiphase flow in porous media. A Darcy's law for steady multiphase flow was investigated for both binary and ternary amphiphilic flow. Linear flux-forcing relationships satisfying Onsager reciprocity were shown to be a good approximation of the simulation data. The dependence of the relative permeability coefficients on water saturation was investigated and showed good qualitative agreement with experimental data. Non-steady state invasion flows were investigated, with particular interest in the asymptotic residual oil saturation. The addition of surfactant to the invasive fluid was shown to significantly reduce the residual oil saturation.

description: Abstract: Background: Normalisation Process Theory (NPT) provides a framework to understand how interventions are implemented, embedded, and integrated in healthcare settings. Previous reviews of published literature have examined the application of NPT across international healthcare and reports its benefits. However, given the distinctive clinical function, organisational arrangements and the increasing management of people with a wide variety of conditions in primary care settings in the United Kingdom, it is important to understand how and why authors utilise and reflect on NPT in such settings to inform and evaluate implementation processes. Methods: A systematic review of peer-reviewed literature using NPT in primary care settings in the United Kingdom (UK) was conducted. Eight electronic databases were searched using replicable methods to identify articles published between January 2012 and April 2018. Data were analysed using a framework approach. Results: Thirty-one articles met the inclusion criteria. Researchers utilised NPT to explore the implementation of interventions, targeting a wide range of health services and conditions, within primary care settings in the UK. NPT was mostly applied qualitatively; however, a small number of researchers have moved towards mixed and quantitative methods. Some variation was observed in the use of NPT constructs and sub-constructs, and whether and how researchers undertook modification to make them more relevant to the implementation process and multiple stakeholder perspectives. Conclusion: NPT provides a flexible framework for the development and evaluation of complex healthcare interventions in UK primary care settings. This review updates the literature on NPT use and indicates that its application is well suited to these environments, particularly in supporting patients with long-term conditions and co-morbidities. We recommend future research explores the receipt of interventions by multiple stakeholders and suggest that authors reflect on justifications for using NPT in their reporting.
Like-Charge Attraction between Metal Nanoparticles in a 1:1 Electrolyte Solution

description: We calculate the force between two spherical metal nanoparticles of charge Q 1 and Q 2 in a dilute 1:1 electrolyte solution. Numerically solving the non-linear Poisson-Boltzmann equation, we find that metal nanoparticles with the same sign of charge can attract one another. This is fundamentally different from what is found for like-charged, non-polarizable, colloidal particles, the two body interaction potential for which is always repulsive inside a dilute 1:1 electrolyte. Furthermore, existence of like-charge attraction between spherical metal nanoparticles is even more surprising in view of the result that such attraction is impossible between parallel metal slabs, showing the fundamental importance of curvature. To overcome a slow convergence of the numerical solution of the full non-linear Poisson-Boltzmann equation, we developed a modified Derjaguin approximation which allows us to accurate and rapidly calculate the interaction potential between two metal nanoparticles, or between a metal nanoparticle and a phospholipid membrane.

description: This contribution asks whether and why the newly political environment of EU law-making impacts on the European Commission's choice (not) to announce the withdrawal of legislative proposals. We argue that the Commission uses ‘responsive withdrawal’ in response to bottom-up pressure, so as to signal self-restraint or policy-determination to different audiences. Bottom-up pressures are driven by (1) the national contestation of ‘Europe’; (2) visible controversy about optimal (crisis) governance; and (3) the domestic salience of EU legislation. Our hypotheses are tested on a new dataset of all codecision files concluded, withdrawn, rejected or ongoing between 2006 and 2018. We show that the Commission reacts to bottom-up pressure by either politicising or depoliticising the EU's legislative agenda: ‘withdrawal announcements’ are more likely when Euroscepticism is high and when legislation touches core state powers, but less likely when legislation is domestically salient. We also demonstrate the continued importance of cyclical and technical reasons. Our analysis complements extant explanations of withdrawal as the upshot of functional factors or of uncertainty, and contributes to the nascent debate about whether, why and how supranational actors respond when the systems in which they operate – and the policies they produce – come under attack.

description: Static and dynamic properties of the quasi-two-dimensional antiferromagnet K$_2$V$_3$O$_8$ have been investigated by $^{51}$V-NMR experiments on nonmagnetic V$^{5+}$ sites. Above the structural transition temperature $T_{\rm{S}}$ = 115 K, NMR spectra are fully compatible with the $P4bm$ space group symmetry. The formation of superstructure below $T_{\rm{S}}$ causes splitting of the NMR lines, which get broadened at lower temperatures so that individual peaks are not well resolved. Evolution of NMR spectra with magnetic field along $c$-axis below the magnetic transition temperature $T_{\rm{N}} \sim 4$ K is qualitatively consistent with a simple Néel order and a spin flop transition. However, broad feature of the spectra does not rule out possible incommensurate spin structure. The spin-lattice relaxation rate $1/T_1$ below $T_{\rm{N}}$ shows huge enhancement for a certain range of magnetic field, which is independent of temperature and attributed to cross relaxation due to anomalously large nuclear spin-spin coupling between V$^{5+}$ and magnetic V$^{4+}$ sites. The results indicate strong gapless spin fluctuations, which could arise from incommesurate orders or complex spin textures.

description: In this article, we analyzed the structures of three acidic hetero-chain polysaccharides (CTP3-B, CTP3-C, and CTP3-D) fractionated from the herb Crepis crocea (Lam.) Babc. by a combination of ethanol precipitation, dialysis and gel permeation chromatography. Three polysaccharides were all highly branched polysaccharide. KK-Ay mice were chosen to determine the hypoglycemic effect of CTP3. The anti-diabetic activity of CTP3 was explored in detail from the aspects of body weight, daily dietary intake, blood glucose level and oral glucose tolerance test (OGTT). It was found that the body weight and daily food intake of the high dose group were significantly decreased compared with the diabetic control group. In addition, there was significant decrease in the levels of blood glucose in the middle and high dose group. These results suggest that CTP3 had a regulative role in blood glucose level. CTP3 may be useful in the treatment of type 2 diabetes mellitus.

description: The Nearest Neighbour Spacing (NNS) distribution can be computed for generalized symmetric 2x2 matrices having different variances in the diagonal and in the off-diagonal elements. Tuning the relative value of the variances we show that the distributions of the level spacings exhibit a crossover from clustering to repulsion as in GOE. The analysis is extended to 3x3 matrices where distributions of NNS as well as Ratio of Nearest Neighbour Spacing (RNNS) show similar crossovers. We show that it is possible to calculate NNS distributions for Hermitian matrices (N=2, 3) where also crossovers take place between clustering and repulsion as in GUE. For large symmetric and Hermitian matrices we use interpolation between clustered and repulsive regimes and identify phase diagrams with respect to the variances.

description: Increasing demands for internet voting instigated the deployment of a multitude of systems used in practice. Within this work, we are interested in which security mechanisms are currently used by vendors to implement verifiable and secret elections.
We perform a systematic market study and review academic literature, where out of 82 candidate systems, we find 29 internet voting systems that are both in active use and claim to employ some form of verifiability. Thereof, we characterize and systematize the 18 systems that provide sufficient information to extract their security mechanisms relevant for state-of-the-art verifiability and secrecy. Overall, we find that only eight systems are well-documented, of which only a few employ state-of-the-art mechanisms in all categories that we consider.

Universal limitations on implementing resourceful unitary evolutions

description: We derive a trade-off relation between the accuracy of implementing a desired unitary evolution using a restricted set of free unitaries and the size of the assisting system, in terms of the resource generating/losing capacity of the target unitary. In particular, this relation implies that, for any theory equipped with a resource measure satisfying lenient conditions, any resource changing unitary cannot be perfectly implemented by a free unitary applied to a system and an environment if the environment has finite dimensions. Our results are applicable to a wide class of resources including energy, asymmetry, coherence, entanglement, and magic, imposing ultimate limitations inherent in such important physical settings, as well as providing insights into operational restrictions in general resource theories.

description: We construct a class of systems for which quantum dynamics can be expanded around a mean field approximation with essentially classical content. The modulus of the quantum overlap of mean field states naturally introduces a classical distance between classical phase points. Using this fact we analytically show that the time rate of change (trc) of two neighbouring classical trajectories is directly proportional to the trc of quantum correlations. Coherence loss and nonlocality effects appear as corrections to mean field dynamics and we show that they can be given in terms of classical trajectories and generalized actions. This result is a first step in the connection between quantum and classically chaotic dynamics in the same sense of semiclassical expansions for the density of states. We apply the results to the nonintegrable (classically chaotic) version of the N-atom Jaynes-Cummings model.

description: Recent improvements in cost-effectiveness of high-throughput technologies has allowed RNA sequencing of total transcriptomes suitable for evaluating the expression and regulation of circRNAs, a relatively novel class of transcript isoforms with suggested roles in transcriptional and post-transcriptional gene expression regulation, as well as their possible use as biomarkers, due to their deregulation in various human diseases. A limited number of integrated workflows exists for prediction, characterization, and differential expression analysis of circRNAs, none of them complying with computational reproducibility requirements. We developed Docker4Circ for the complete analysis of circRNAs from RNA-Seq data. Docker4Circ runs a comprehensive analysis of circRNAs in human and model organisms, including: circRNAs prediction; classification and annotation using six public databases; back-splice sequence reconstruction; internal alternative splicing of circularizing exons; alignment-free circRNAs quantification from RNA-Seq reads; and differential expression analysis. Docker4Circ makes circRNAs analysis easier and more accessible thanks to: (i) its R interface; (ii) encapsulation of computational tasks into docker images; (iii) user-friendly Java GUI Interface availability; and (iv) no need of advanced bash scripting skills for correct use. Furthermore, Docker4Circ ensures a reproducible analysis since all its tasks are embedded into a docker image following the guidelines provided by Reproducible Bioinformatics Project.

description: There are many different vehicles that can be used to conserve land within towns. For example, towns can spend money on conservation through open space related expenditures in their budget, residents can vote on a referendum to fund conservation with bonds, private land trusts can purchase land development rights, and governmental grants can be used to fund conservation. The attraction or repulsion of funding sources for land conservation have only been investigated in some of these vehicles, however. Our paper investigates the spatial relationship between conservation funding sources that have not been examined before in a regression discontinuity framework.

description: This paper describes how factor markets are presented in applied equilibrium models and how we plan to improve and to extend the presentation of factor markets in two specific models: MAGNET and ESIM. We do not argue that partial equilibrium models should become more ‘general’ in the sense of integrating all factor markets, but that the shift of agricultural income policies to decoupled payments linked to land in the EU necessitates the inclusion of land markets in policy-relevant modelling tools. To this end, this paper outlines options to integrate land markets in partial equilibrium models. A special feature of general equilibrium models is the inclusion of fully integrated factor markets in the system of equations to describe the functionality of a single country or a group of countries. Thus, this paper focuses on the implementation and improved representation of agricultural factor markets (land, labour and capital) in computable general equilibrium(CGE) models. This paper outlines the presentation of factor markets with an overview of currently applied CGE models and describes selected options to improve and extend the current factor market modelling in the MAGNET model, which also uses the results and empirical findings of our partners in this FP project.
Agility is responsiveness to change: An essential definition

description: There is some ambiguity of what agile means in both research and practice. Authors have suggested a diversity of different definitions, through which it is difficult to interpret what agile really is. The concept, however, exists in its implementation through agile practices. In this vision paper, we argue that adopting an agile approach boils down to being more responsive to change. To support this claim, we relate agile principles, practices, the agile manifesto, and our own experiences to this core definition. We envision that agile transformations would be, and are, much easier using this definition and contextualizing its implications.
Dynamical Windings of Random Walks and Exclusion Models. Part I: Thermodynamic Limit

description: We consider a system consisting of a planar random walk on a square lattice, submitted to stochastic elementary local deformations. Depending on the deformation transition rates, and specifically on a parameter $η$ which breaks the symmetry between the left and right orientation, the winding distribution of the walk is modified, and the system can be in three different phases: folded, stretched and glassy. An explicit mapping is found, leading to consider the system as a coupling of two exclusion processes. For all closed or periodic initial sample paths, a convenient scaling permits to show a convergence in law (or almost surely on a modified probability space) to a continuous curve, the equation of which is given by a system of two non linear stochastic differential equations. The deterministic part of this system is explicitly analyzed via elliptic functions. In a similar way, by using a formal fluid limit approach, the dynamics of the system is shown to be equivalent to a system of two coupled Burgers' equations.

description: We assess the tradeoffs and synergies involved in reducing agriculture-generated nutrient loads with different levels of resilience. We optimize the selection of least-cost patterns of agricultural conservation practices for both the expected performance of the conservation actions and its variance. Securing nutrient loads with a higher level of resilience is costly, with marginal costs of resilience generally declining with lower loads. We find that the main tradeoff dimension is between cost of conservation investments and ecosystem service objectives, as opposed to pronounced mean-variance or between- nutrient objectives tradeoffs. We find relative synergies in agricultural conservation investments aimed at nutrient reductions.

description: MAXI J1957+032 is a transient Low-mass X-ray binary (LMXB) that underwent four short outbursts in 1.5 years since its discovery in 2015. The nature of the compact object in MAXI J1957+032 is not clear, but it was proposed to be a neutron star based on the short-duration of its outbursts. Here, we report the results obtained after performing spectral analysis using data obtained with the X-ray telescope aboard the Neil Gehrels Swift satellite. When describing the spectrum with an absorbed power law, we found that the spectra softens (the power-law index increases from $\sim$ 1.8 to 2.5) as the luminosity decreases. Near the end of its outbursts the observed value of power-law index ($Γ$) is $\sim$ 2.5. To identify the nature of the compact object in this system, we used $Γ$ as a tracer of the spectral evolution with luminosity. We found that for the distance of 4 kpc, our results suggest that the source harbours a neutron star.

description: In a world free of transaction costs, reverse auctions can cost-effectively allocate payment for environmental service contracts by targeting projects that provide the most benefit per dollar spent. However, auctions only succeed if enough farmers choose to bid so that the auctioneer can evaluate numerous projects for targeted funding. A 2014 conservation auction to allocate payments for phosphorus reduction practices in NW Ohio experienced very thin bidding. According to a follow-up survey, auction participation was deterred by the complexity of the bidding process and the need to negotiate with renters. Due to low participation, the actual conservation auction made payments for phosphorus reduction that were surprisingly costly at the margin. Applying a farmer behavioral model to the Western Lake Erie Basin, we simulate participation choice and cost-effectiveness of environmental outcomes in reverse auctions and uniform payment conservation programs. Results reveal that when perceived transaction costs of bid preparation are high, reverse auctions are less cost-effective than spatially targeted, uniform payment programs that attract higher participation. Keywords: reverse auctions, transaction costs, cost-effective, conservation programs, endogenous participation

description: We study Higgs boson production via Double Pomeron Exchange allowing for the presence of Pomeron remnants. We estimate the number of events produced at the LHC collider, as a function of the Higgs boson mass and its decay channel. The model which successfully describes the high mass dijet spectrum observed at Tevatron (run I) is used to predict rates of events with tagged protons for the acceptance range of the CMS/Totem experiments. Sizeable cross-sections and encouraging event selection signals are found, demonstrating especially for smaller Higgs boson masses the importance to study the diffractive channels. Tagging of the Pomeron remnants can be exploited to achieve a good resolution on the Higgs boson mass for inclusive diffractive events, by optimizing an intermediary analysis between higher cross-sections of the fully {\it inclusive} mode (all Pomeron remnants) and cleaner signals of the {\it exclusive} mode (without Pomeron remnants).

Non-isolated masonry towers

description: Abstract: The new Italian building code, published in 2018 [MIT in NTC 2018: D.M. del Ministero delle Infrastrutture e dei trasporti del 17/01/2018. Aggiornamento delle Norme Tecniche per le Costruzioni (in Italian), 2018], explicitly refers to the Italian “Guidelines for the assessment and mitigation of the seismic risk of the cultural heritage” [PCM in DPCM 2011: Direttiva del Presidente del Consiglio dei Ministri per valutazione e riduzione del rischio sismico del patrimonio culturale con riferimento alle norme tecniche per le costruzioni, G.U. n. 47 (in Italian), 2011] as a reliable source of guidance that can be employed for the vulnerability assessment of heritage buildings under seismic loads. According to these guidelines, three evaluation levels are introduced to analyse and assess the seismic capacity of historic masonry structures, namely: (1) simplified global static analyses; (2) kinematic analyses based on local collapse mechanisms, (3) detailed global analyses. Because of the complexity and the large variety of existing masonry typologies, which makes it particularly problematic to adopt a unique procedure for all existing structures, the guidelines provide different simplified analysis approaches for different structural configurations, e.g. churches, palaces, towers. Among the existing typologies of masonry structures there considered, this work aims to deepen validity, effectiveness and scope of application of the Italian guidelines with respect to heritage masonry towers. The three evaluation levels proposed by the guidelines are here compared by discussing the seismic risk assessment of a representative masonry tower: the Cugnanesi tower located in San Gimignano (Italy). The results show that global failure modes due to local stress concentrations cannot be identified if only simplified static and kinematic analyses are performed. Detailed global analyses are in fact generally needed for a reliable prediction of the seismic performance of such structures.

description: Food processing firms vary in size, exhibit productivity differences, engage in monopolistic competition, and produce highly differentiated products. As the TTIP negotiation is gaining momentum and trade in processed food is becoming more important, it is worth analyzing the impact of this potential trade liberalization on the US and EU processed food markets. This study develops a three-region (United Staates, European Union, and ROW) monopolistic competition trade model with heterogeneous firms to analyze the effects of US-EU bilateral tariff elimination and non-tariff barrier harmonization on prices, domestic production, consumption, bi-lateral trade, cutoff productivity levels, and aggregate productivity in the processed food sector. The empirical results show that this trade liberalization expands cross hauling, with US exports to the European Union increasing b 113.58% and EU exports to the United States rising by 96.19%. This increased cross hauling displaces exports from ROW to the United States and European Union by 47.26% and 16.10%, respectively. US and EU processed food production increases by 4.89% and 3.91%, respectively. Consequently, aggregate utility expands in all three regions.

description: It is common to consider mass politics and Eurosceptic politicization as ‘post-functionalist’ constraints that encourage differentiated European integration. This study argues that the relevance of Euroscepticism depends on who wins the domestic competition for government office. European mass politics are organized as delegation systems. These systems concentrate authority in the government and give little influence to parliaments and publics. If Eurosceptic parties reach the government, they will push for differentiation and even disintegration. If pro-EU parties succeed, uniform integration is likely to prevail. An empirical analysis of differentiated integration from the 1992 Maastricht Treaty to the 2016 Single Resolution Fund shows that only government Euroscepticism – rather than opposition, extra-parliamentary, or popular Euroscepticism – encourages differentiation. This study explains how uniform integration can prevail even in ostensibly Eurosceptic countries. It suggests that the impact of Eurosceptic politicization depends on party competition and is often more limited than might seem at first sight.

description: By employing the perturbative QCD (PQCD) factorization approach, we studied the sixteen $B/B_s \to η_c (π, K, η^{(\prime)},ρ,K^*,ω,ϕ)$ decays with the inclusion of the currently known next-to-leading order (NLO) contributions. We found the following main points: (a) for the five measured $B \to η_c (K,K^*)$ and $B_s\to η_cϕ$ decays, the NLO contributions can provide $ (80-180)\%$ enhancements to the leading order (LO) PQCD predictions of their branching ratios, which play an important role to help us to interpret the data; (b) for the seven ratios $R_{1,\cdots,7}$ of the branching ratios defined among the properly selected pair of the considered decay modes, the PQCD predictions for the values of $R_{3,4,5}$ agree well with those currently available measurements from BaBar and Belle Collaboration; (c) for $B^0 \to η_c K_S^0$ decay, the PQCD predictions for both the direct and mixing induced CP asymmetries do agree very well with the measured values within errors; and (d) the PQCD predictions for ratios $R_{1,2}$ and $R_{6,7}$ also agree with the general expectations and will be tested by the future experiments.

description: This article reviews approaches to voluntary nutrition labeling (VNL), such as front-ofpackage (FOP) labels, that emerged in the 2001-2014 period to provide simplified nutrition information, thus lowering the search cost for nutritional information. We present a market model to assess consumer and producer responses to changes in information search cost brought about by VNL. We specifically focus on the introduction of VNL in the ready-toeat cereal (RTEC) market and illustrate trends in labeling and the overall healthfulness of RTEC products. Both the conceptual and empirical evidence suggest that VNL has been instrumental in attaining a healthier RTEC market. Finally, we suggest a research agenda to further theory development and empirical (experimental and big data) research to better comprehend the role of VNL in relation to market healthfulness.

description: Large amounts of occasional voters participated in the Brexit referendum. Did the increase in turnout affect the referendum outcome? For an answer, we exploit exogenous variation in voting costs, as large amounts of rainfall made voting more inconvenient in some areas. With an instrumental variable approach, we show that citizens whose voting benefits just surpassed costs under normal circumstances predominantly supported Leave. Hence, the turnout increase likely led to a larger Leave vote share. Exploring the reason for this with survey data, we show that Leave support was not generally higher in the population of low-propensity voters. Rather, the mobilisation of Leave-leaning, compared to Remain-leaning occasional voters was lopsided: The former were more likely to turn out. Our research highlights that the issue-specific mobilisation of low-propensity voters helps to explain electoral outcomes. This is particularly so in referendums with weak partisan preferences, and where single issues dominate voter decision making.
