description: Background: The computation of the statistical properties of motif occurrences has an obviously relevant practical application: for example, patterns that are significantly over- or under-represented in the genome are interesting candidates for biological roles. However, the problem is computationally hard; as a result, virtually all the existing pipelines use fast but approximate scoring functions, in spite of the fact that they have been shown to systematically produce incorrect results. A few interesting exact approaches are known, but they are very slow and hence not practical in the case of realistic sequences. Results: We give an exact solution, solely based on deterministic finite-state automata (DFAs), to the problem of finding not only the p-value, but the whole relevant part of the Markovian probability distribution function of a motif in a biological sequence. In particular, the time complexity of the algorithm in the most interesting regimes is far better than that of Nuel (2006), which was the fastest similar exact algorithm known to date; in many cases, even approximate methods are outperformed. Conclusions: DFAs are a standard tool of computer science for the study of patterns, but so far they have been sparingly used in the study of biological motifs. Previous works do propose algorithms involving automata, but there they are used respectively as a first step to build a Finite Markov Chain Imbedding (FMCI), or to write a generating function: whereas we only rely on the concept of DFA to perform the calculations. This innovative approach can realistically be used for exact statistical studies of very long genomes and protein sequences, as we illustrate with some examples on the scale of the human genome.

description: This paper empirically investigates the impact of agricultural trade reform in South Africa. Using UNCTAD’s Agricultural Trade Policy Simulation Model (ATPSM), the study investigates two specific scenarios that capture the magnitude of (i) the economic impact of global agricultural trade reform in South Africa and (ii) the economic impact if the reform in South Africa is coupled with agricultural reforms in the European Union (EU). Trade reform focuses on substantial tariff reduction; although in the case of the EU, scenarios also include reduction in domestic support and export subsidies. The results show that a unilateral tariff reduction in a selected number of agricultural products amounts to welfare gains of US$21 million. These gains are three times higher when accompanied by extensive reforms in the EU.

description: Active force generation by actin-myosin cortex coupled to the cell membrane allows the cell to deform, respond to the environment, and mediate cell motility and division. Several membrane-bound activator proteins move along it and couple to the membrane curvature. Besides, they can act as nucleating sites for the growth of filamentous actin. Actin polymerization can generate a local outward push on the membrane. Inward pull from the contractile actomyosin cortex can propagate along the membrane via actin filaments. We use coupled evolution of fields to perform linear stability analysis and numerical calculations. As activity overcomes the stabilizing factors such as surface tension and bending rigidity, the spherical membrane shows instability towards pattern formation, localized pulsation, and running pulsation between poles. We present our results in terms of phase diagrams and evolutions of the coupled fields. They have relevance for living cells and can be verified in experiments on artificial cell-like constructs.

description: Both Zn-doping and $c$-axis magnetic fields have been observed to increase the spin stripe order in La$_{2-x}$Ba$_x$CuO$_4$ with $x$ close to 1/8. For $x=0.095$, the applied magnetic field also causes superconducting layers to decouple, presumably by favoring pair-density-wave order that consequently frustrates interlayer Josephson coupling. Here we show that introducing 1% Zn also leads to an initial onset of two-dimensional (2D) superconductivity, followed by 3D superconductivity at lower temperatures, even in zero field. We infer that the Zn pins pair-density-wave order locally, establishing the generality of such behavior.

description: In this paper, we study block-block entanglement in the ground state of one-dimensional extended Hubbard model. Our results show that the phase diagram derived from the block-block entanglement manifests richer structure than that of the local (single site) entanglement because it comprises nonlocal correlation. Besides phases characterized by the charge-density-wave, the spin-density-wave, and phase-separation, which can be sketched out by the local entanglement, singlet superconductivity phase could be identified on the contour map of the block-block entanglement. Scaling analysis shows that ${\rm log}_2(l)$ behavior of the block-block entanglement may exist in both non-critical and the critical regions, while some local extremum are induced by the finite-size effect. We also study the block-block entanglement defined in the momentum space and discuss its relation to the phase transition from singlet superconducting state to the charge-density-wave state.

description: The Schwarzschild wormhole has been interpreted as an entangled state. If Alice and Bob fall into each of the black hole, they can meet in the interior. We interpret this meeting in terms of the quantum circuit that prepares the entangled state. Alice and Bob create growing perturbations in the circuit, and we argue that the overlap of these perturbations represents their meeting. We compare the gravity picture with circuit analysis, and identify the post-collision region as the region storing the gates that are not affected by any of the perturbations.

description: Past research on agricultural loan pricing is not extensive and has been hampered by a lack of suitable data. The Farm Service Agency (FSA) has guaranteed approximately 5 percent of farm debt of the Farm Credit System (FCS) and banks, the primary lenders to agriculture. As a requirement of the farm loan guarantee program, lenders must charge interest rates on these loans that are no different than their average or moderate risk farm loan customer. Therefore, rates on FSA guaranteed loans may be viewed as proxies for average farm loan interest rates. Using agency data bases, interest rates on nearly 100,000 farm loans guaranteed from fiscal 1999 to fiscal 2007 where compared with commercial farm loan rates and market-rate benchmarks. The study indicates that interest rates on FSA guaranteed loans are generally consistent with rates reported on various surveys of bank farm lending terms, but it also found that during certain periods guaranteed farm loan rates and non-guaranteed farm loan rates were less responsive to changes in market interest rates. In general, rates on guaranteed loans of the FCS were lower and more responsive to market rate conditions than guaranteed loans made by banks during the eight year study period.

description: It is shown that the scattering of electromagnetic waves by Langmuir ones taking into the account the electric drift motion of particles, is the most intense nonlinear process and should be responsible for the formation of radiation spectrum of radio pulsars. Performed analysis indicates that in the case of existence of inertial interval formation of stationary spectra is possible. Analysis of linear mechanisms of wave generation and silk allows to conclude that only possible stationary solution has spectral index $α=-1.5$. Obtained spectrum is in good agreement with observational data.

description: This study analyses the determinants of off-farm work participation decisions of farm households in Ethiopia. A bivariate probit model is applied to account for the simultaneity of participation decisions of both male and female members of farm households. The results of the analysis show that human capital variables such as health and training on non-farm activities have a positive effect on the off-farm participation decisions of male members of farm households. The education status of the head has no significant impact on the participation decisions of the members of the family as most of the off-farm activities do not require formal education. The availability of credit and transfer income is the other factors that have a positive impact on the decisions of male members to participate in off-farm activities. The effects of family and farm characteristics are also analysed. Finally, policies that aim to increase the off-farm work participation decisions of family members should take into consideration the difference in responses to the various factors that affect the off-farm work decisions of male and female members of farm households.

description: The theory of $C^*$-algebras traces its origins back to the development of quantum mechanics and it has evolved into a large and highly active field of mathematics. Much of the progress over the last couple of decades has been driven by an ambitious program of classification launched by George A. Elliott in the 1980s, and just recently this project has succeeded in achieving one of its central goals in an unexpectedly dramatic fashion. This Snapshot aims to recount some of the fundamental ideas at play.

description: Risk aversion is the primary reason for farmers to use forward pricing methods to hedge against price risk. Previous international research on farmers’ forward pricing behaviour found inconsistent results with respect to the relationship between risk aversion and the use of forward pricing methods. Ordinary Least Squares (OLS) regression is used in this research to investigate the relationship between the proportion of maize Vaalharts maize producers are willing to forward price and risk aversion. The quantity decision is modelled conditional on the adoption decision to ensure that the modelling procedure does not force the same variables to influence the two decisions in the same way. Regression results showed that more risk averse farmers are forward pricing a larger proportion of their crop produce. The main conclusion from this research is that the relationship between farmers’ risk aversion and the quantity of maize forward priced is consistent with expected utility theory in spite of the fact that farmers needs to be less risk averse to adopt forward pricing. Future emphases should be placed on the factors affecting the adoption of forward pricing as risk management tool in order to promote risk management. Especially research that will change farmers’ perception about forward pricing is necessary.

description: The sugar industry is an important contributor to the South African (SA) economy, with average annual production estimated at 2.5 million tons of sugar. This study aims to quantify actual use of management instruments by a sample of commercial sugarcane farmers in KwaZulu-Natal (KZN) that are commonly associated with risk management, and uses factor analysis to investigate the extent to which these farmers bracket their management decisions. Data were obtained in 2006 via personal interviews of a stratified random sample of 76 large-scale sugarcane farmers in two separate mill-supply areas of KZN. Respondents were asked questions regarding risk-related management strategies, including diversification of on-farm enterprises, investments and management time. Factor analysis identified six management choice brackets, collectively explaining 77% of the variance in all of the 12 risk-related management responses considered. Recommendations that stem from these findings include that policy makers create a more enabling business environment and that government make labour legislation more flexible. Farmers need to search for information more proactively and develop management strategies that reduce barriers to efficiency. Future research based on time series data could be important to identify how management portfolios and choice bracketing levels change over time.

description: Clearing of trees and native vegetation over the past 160 years has led to increasing rates of dryland salinization in the Goulburn-Broken Catchment area. In its dryland section, within the Goulburn Highlands, South West Goulburn, and the Broken Highlands subcatchments, hydrologic balance exists. But in the Riverine Plains comprising the Goulburn and Broken Plains sub-catchments, where average annual rainfalls are less than 600 mm per annum, it will be many decades before hydrologic balance is achieved. This study is set in the Broken Plains sub-catchment where over the next 100 years, it is expected that deep drainage of annual rainfall will cause watertables to rise to within two metres of the ground surface. Such rises of groundwater will lead to marked land degradation, initially in the form of induced waterlogging and ultimately increased dryland salinity. There is therefore a critical need to redress this increasing problem. One main way of doing so is by introducing deep-rooted perennial species such as lucerne into the landscape. Lucerne has a higher level of water extraction than annual crops and pasture. However, one of the barriers to farmers changing from annual subterranean clover pasture to lucerne is uncertainty about the effects of such a change and the chance of reduced average profit or its volatility. This study seeks to reduce that uncertainty by investigating changes in profitability and cash flow across the Broken Plains sub-catchment where farming with lucerne replaces cropping with subterranean clover pasture.

description: A simple illustrative wave function with only three variational parameters is suggested to calculate the binding energy of negatively charged excitons (X-) as a function of quantum well width. The results of calculations are in agreement with experimental data for GaAs, CdTe and ZnSe quantum wells, which differ considerably in exciton and trion binding energy. The normalized X- binding energy is found to be nearly independent of electron-to-hole mass ratio for any quantum well heterostructure with conventional parameters. Its dependence on quantum well width follows an universal curve. The curve is described by a simple phenomenological equation.

description: Participation is a relative concept. Too much implies high costs of administration and many losers in a competitive process. Too little implies relatively few gains from trade are accessed. Thus the aim is to optimise rather than maximise participation. In this paper we outline some rules of thumb for setting participation targets and develop a framework for identifying barriers to achieving targets. We use the framework to evaluate six case study tenders covering a variety of land management objectives. These case studies provided pragmatic on-ground lessons in managing participation in real tender applications and resulted in several further lessons for participation management in tender design.

description: Introduction : La prise en charge actuelle des patients hospitalisés en psychiatrie se heurte à plusieurs problématiques. D’une part, les traitements médicamenteux donnés pour soulager les symptômes présentent un nombre important d’effets secondaires. D’autre part, la pratique de l’isolement utilisée pour gérer l’agressivité et la violence fait débat pour des questions d’éthique. Objectif : Identifier le rôle des approches corporelles dans la gestion des symptômes perturbateurs en milieu hospitalier psychiatrique. Méthodologie : Les bases de données CINAHL et PsycINFO ont été utilisées pour la recherche d’articles. Six articles ont été sélectionnés afin d’atteindre l’objectif de ce travail. Résultats : Trois approches corporelles ont été identifiées ; la modulation sensorielle, l’enveloppement thérapeutique et la relaxation musculaire progressive. Les principaux bénéfices de la modulation sensorielle mis en avant sont : une diminution de l’agitation et de l’anxiété, une augmentation de l’empowerment, une meilleure gestion et expression des émotions, la création d’une relation de confiance et enfin la création d’un espace sécuritaire. Elle semble aussi constituer une piste pour diminuer l’isolement. L’enveloppement thérapeutique semble diminuer l’anxiété et permettre la réintégration des limites corporelles. Il semble aussi constituer une piste dans la diminution des traitements médicamenteux, notamment les benzodiazépines. Finalement, la relaxation musculaire progressive a démontré son efficacité dans la diminution de l’anxiété. Discussion : Ces approches pourraient faire office d’étapes supplémentaires avant l’isolement ou avant l’utilisation de thérapies verbales. De plus, elles pourraient constituer des outils supplémentaires pour la pratique clinique infirmière et renforcer ainsi leur rôle propre.

description: This article evaluates irrigated agriculture sector response and resultant economic impacts of climate change for a part of the Murray Darling Basin in Australia. A water balance model is used to predict reduced basin inflows for mild, moderate and severe climate change scenarios involving 10, 20, 40 Celcius warming, and predict 13%, 38% and 63% reduced inflows. Impact on irrigated agricultural production and profitability are estimated with a mathematical programming model using a two-stage approach that simultaneously estimates short and long-run adjustments. The model accounts for a range of adaptive responses including: deficit irrigation, temporarily fallowing some areas, and permanently reducing irrigated area and changing the mix of crops. The results suggest that relatively low cost adaptation strategies are available for moderate reduction in water availability and thus costs of such reduction are likely to be relatively small. In more severe climate change scenarios greater costs are estimated, adaptations predicted include a reduction in total area irrigated, investments in efficient irrigation, and a shift away from perennial to annual crops as the latter can be managed more profitably when water allocations in some years are very low.

description: We investigate cosmologies where the accelerated expansion of the Universe is driven by a field with an anisotropic equation of state. We model such scenarios within the Bianchi I framework, introducing two skewness parameters to quantify the deviation of pressure from isotropy. We study the dynamics of the background expansion in these models. A special case of anisotropic cosmological constant is analyzed in detail. The anisotropic expansion is then confronted with the redshift and angular distribution of the supernovae type Ia. In addition, we investigate the effects on the cosmic microwave background (CMB) anisotropies for which the main signature appears to be a quadrupole contribution. We find that the two skewness parameters can be very well constrained. Tightest bounds are imposed by the CMB quadrupole, but there are anisotropic models which avoid this bound completely. Within these bounds, the anisotropy can be beneficial as a potential explanation of various anomalous cosmological observations, especially in the CMB at the largest angles. We also consider the dynamics of linear perturbations in these models. The covariant approach is used to derive the general evolution equations for cosmological perturbations taking into account imperfect sources in an anisotropic background. The implications for the galaxy formation are then studied. These results might help to make contact between the observed anomalies in CMB and large scale structure and fundamental theories exhibiting Lorentz violation.

description: We present a blueprint for a maser with a single three-level transmon superconducting artificial atom. The system can be pumped coherently via a two-photon process, and to achieve high population inversion, the relaxation rate of the metastable state is increased via an auxiliary low-Q cavity coupled to a transition between the transmon excited states. We show numerically that such a maser can operate both in the intermediate coupling regime with super-Poissonian photon statistics and in the strong coupling regime, where the statistics is sub-Poissonian. For the former, the maser exhibits thresholdless behavior and for the latter, there is a well-defined pumping threshold. A useful side-effect of the auxiliary resonator is that it allows to overcome the photon blockade effect for the pump, which would otherwise prevent high photon population. Finally, we observe the bistability of the steady-state Wigner function and the self-quenching effect for some parameters.

description: It is shown that a Bose gas of two-level atoms in the intense resonant laser field at zero temperature is a mixture of two condensates with a definite ratio of the densities. The criteria of stability are found for the stationary states of such system against the increment of the amplitudes of quasi Bogoliubov elementary excitations. Besides the usual acoustic mode the gap mode is shown to exist and the magnitude of the gap is proportional to the laser field amplitude. The involvement of the gas nonideality under definite conditions results in an instability and decay of the condensates.

Nous avons sélectionné six articles quantitatifs selon des critères d’inclusion et d’exclusion spécifiques. Résultats : Les principaux résultats de nos études relèvent principalement une diminution des symptômes psychiques (l’anxiété et la dépression) et physiques (les douleurs). De plus il en ressort une amélioration des habitudes de vie et une diminution de la consommation de médicaments. Discussion : Nos articles se basent majoritairement sur une population saine ayant des symptômes de souffrance psychique. Nous avons utilisé le cadre théorique de Martha Rogers qui propose une vision unitaire de la personne ce qui nous a permis d’avoir une nouvelle perspective sur le sens des symptômes. Conclusion : Ce travail permet de mettre en avant l’efficacité du shiatsu pour l’amélioration de la santé et du bien-être de la personne. Malgré le fait que ce travail ne s’inscrit pas précisément dans le contexte infirmier, les différents résultats encouragent l’intégration du shiatsu dans la pratique des soins habituellement prodigués.

description: Following the May 2003 Canadian BSE case, food safety issues have become even more prominent to policymakers and consumers. In both Canada and the US, governments and industry have responded with a variety of quality assurance, traceability and labeling schemes. However, there is little information available on the extent to which consumer perceptions differ regionally across North America towards labeling schemes. This paper attempts to fill this gap, by providing results on a variety of beef labeling strategies from choice experiments that were conducted in Alberta (Canada) and Montana (US). The analysis focuses on consumers' perceptions towards negative voluntary labeling with regard to BSE testing, genetically modified organisms (GMO) and the use of growth hormones in beef production. We find that four years after the first BSE case emerged in North America, consumers are willing to pay most to avoid risks associated with BSE. Montana and Alberta consumers are found not to be significantly heterogeneous in their preferences.

As one application we show that the iterated Bing doubles of many algebraically slice knots are not topologically slice. Some of the proofs do not use the existence of the Cheeger-Gromov bound, a deep analytical tool used by Cochran-Teichner. We define generalized doubling operators, of which Bing doubling is an instance, and prove our nontriviality results in this more general context. Our main examples are boundary links that cannot be detected in the algebraic boundary link concordance group.

description: This paper explores socio-demographic, economic and behaviour factors influencing body mass index (BMI) amongst 20 to 64 year old adults in Canada. BMI scores in Canada have increased, with gains stemming from disproportionate increases in female BMI. Econometric results indicate higher BMI scores for males, those born in Canada, those in food insecure homes and whites. Age-gender interactions suggest different patterns of BMI adjustment over the life of males and females; a pronounced inverse quadratic relationship between with age and male BMI is noted, while female BMI increases with age. Education, used as a gauge of inequality, is inversely related to BMI, while income has a muted effect. BMI is inversely related to level of physical activity, an effect which is more pronounced for females in Canada. BMI has an inverse quadratic relationship with smoking behaviour, with higher BMI amongst former smokers than daily, occasional and non-smokers. BMI appears to be inversely related to intensity of alcohol consumption.

Subjects: AGRICORE H2020

description: The purpose of the present report is to provide a general overview of gender equality in Research and Innovation Actions following the perspective and the key ambitions of Horizon 2020 framework programme. The first of the key ambitions is to provide a brief description of the latest directives of EU describing the elimination of gender mainstreaming in research. The second part relates to the strategic approach of gender equality within the Agricore project. The content aims to briefly describe the support of gender balance in project research activities and decision making possesses along with the systematic review of the role of gender in agriculture and rural developments. 

This report is part of WP10 that is dedicated to the Project Management where an entire Task covers the overview of the directives for gender equality and non-discrimination. (Task 10.9- Gender Dimension as presented in the Grant Agreement). The point of attention of the Task 10.9 is to avoid any potential gender biases within the project framework in general but additionally within the research towards the development of the smart IT platform services in agriculture. To summarize all the related attributes Deliverable “D10.7- Gender equality and nondiscrimination within AGRICORE” has been structured at the very beginning of the project to reassure all the necessary activities towards gender equality.
Neural Spatio-Temporal Point Processes

description: We propose a new class of parameterizations for spatio-temporal point processes which leverage Neural ODEs as a computational method and enable flexible, high-fidelity models of discrete events that are localized in continuous time and space. Central to our approach is a combination of continuous-time neural networks with two novel neural architectures, i.e., Jump and Attentive Continuous-time Normalizing Flows. This approach allows us to learn complex distributions for both the spatial and temporal domain and to condition non-trivially on the observed event history. We validate our models on data sets from a wide variety of contexts such as seismology, epidemiology, urban mobility, and neuroscience.

description: Feruloyl esterases (FAEs, E.C. 3.1.1.73, CAZy family CE1) and glucuronoyl esterases (GEs, E.C. 3.1.1.-, CAZy family CE15) are involved in the degradation of plant biomass by hydrolysing ester linkages in plant cell walls, and thus have potential use in biofuel production from lignocellulosic materials and in biorefinery applications with the aim of developing new wood-based compounds [1, 2]. GEs and FAEs are present in the genomes of a wide range of fungi and bacteria.

Under conditions of low water content, these enzymes can also carry out (trans)esterification reactions, making them promising biocatalysts for the modification of compounds with applications in the food, cosmetic and pharmaceutical industry. Compared to the chemical process, enzymatic synthesis can be carried out under lower process temperatures (50-60°C) and results in fewer side products, thus reducing the environmental impact.

We characterized new FAE and GE enzymes from mesophilic, thermophilic and cold-tolerant filamentous fungi produced in Pichia pastoris. On one hand, we investigated their hydrolytic abilities on various model substrates for potential applications in deconstruction of lignocellulosic materials and extraction of valuable compounds. On the other hand, we tested and optimised the FAEs’ transesterification capabilities on ferulate esters in a 1-butanol-buffer system, with the aim of using the most promising candidates for the production of antioxidant compounds with improved hydrophobic or hydrophilic properties, such as prenyl ferulate, prenyl caffeate, glyceryl ferulate and 5-O-(trans-feruloyl)-arabinofuranose.
An Evaluation of Permissive Left-Turn Phasing

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1979
Subjects: subject: Transportation Engineering

description: In this study, exclusive left-turn phasing was replaced with permissive left-turn phasing at four trial intersections. Delay and accident studies were done before and after the trial installations. Also, a questionnaire was issued to determine public opinion concerning the signals.  The use of permissive-turn phasing resulted in a 50-percent reduction in left-turn delay and a 24-percent reduction in total delay compared to exclusive phasing. The permissive left-turn phasing did result in an increase in left-turn accidents. Other accident types, such as rear-end accidents, did not change. The number of left-turn accidents decreased as drivers became more familiar with the signals. Questionnaire responses showed that over 90 percent of drivers were in favor of this type of signal. An economic analysis showed that all but one of the locations had benefit-cost ratios much higher than one when a 1-year "after" period was considered. All locations had benefit-cost ratios greater than one when an additional 6 months of accident data were taken into account.  The reductions in delay are encouraging toward additional but discriminating use of permissive left-turn phasing; and, indeed, the increased accident potential limits its use to intersections where an accident problem will not be created.

description: The celebrated tenfold-way of Altland-Zirnbauer symmetry classes discern any quantum system by its pattern of non-spatial symmetries. It lays at the core of the periodic table of topological insulators and superconductors which provided a complete classification of weakly-interacting electrons' non-crystalline topological phases for all symmetry classes. Over recent years, a plethora of topological phenomena with diverse surface states has been discovered in crystalline materials. In this paper, we obtain an exhaustive classification of topologically distinct groundstates as well as topological phases with anomalous surface states of crystalline topological insulators and superconductors for key space-groups, layer-groups, and rod-groups. This is done in a unified manner for the full tenfold-way of Altland-Zirnbauer non-spatial symmetry classes. We establish a comprehensive paradigm that harnesses the modern mathematical framework of equivariant spectra; it allows us to obtain results applicable to generic topological classification problems. In particular, this paradigm provides efficient computational tools that enable an inherently unified treatment of the full tenfold-way.
