description: Millions of mines lie in or on the ground in 62 countries resulting in thousands of deaths and injuries each year. Most mines are cleared using probes and hand held mine detectors; although sniffer dogs and a variety of machines are becoming more common. Clearing landmines is very expensive with costs often reaching US$10 per square metre; over US$1.5 billion has been spent on clearing mines since 1992. Most of the organisations involved in mine clearance have concentrated on technical aspects and put less emphasis on the most cost effective way of getting the job done. This paper reviews the contribution that economists can make in the area of humanitarian mine clearance and describes the development of a software package and manual designed to help managers decide which combination of machine and manual methods should be used to clear minefields to the required safety standard at the lowest cost.

description: Nitrogen leaching from agriculture contributes to contamination of Lake Taupo. Multiple criteria decision making was used to compare fourteen pre-defined farming systems which reduced, or maintained nitrogen losses. Case study participants included three to four each of Maori Incorporation representatives, owner-operators, Environment Waikato employees, and researchers. The total group identified criteria that were important in choosing between the systems. Profit and nitrogen outputs were provided for the systems. Individuals weighted criteria and subjectively scored each system’s performance against the remaining criteria. Systems were ranked using this information. Variation within and between groups was considerable. Key criteria included: profit; farm sustainability; labour; enjoyment; risk (Maori); lifestyle and environmental sustainability (owner-operators).

description: Optical-coherence tomography (OCT) is a technique that employs light in order to measure the internal structure of semi-transparent, e.g. biological, samples. It is based on the interference pattern of low-coherence light. Quantum-OCT (QOCT), instead, employs the correlation properties of entangled photon pairs, for example, generated by the process of spontaneous parametric downconversion (SPDC). The usual QOCT scheme uses photon pairs characterised by a joint-spectral amplitude with strict spectral anti-correlations. It has been shown that, in contrast with its classical counterpart, QOCT provides resolution enhancement and dispersion cancellation. In this paper, we revisit the theory of QOCT and extend the theoretical model so as to include photon pairs with arbitrary spectral correlations. We present experimental results that complement the theory and explain the physical underpinnings appearing in the interference pattern. In our experiment, we utilize a pump for the SPDC process ranging from continuous wave to pulsed in the femtosecond regime, and show that cross-correlation interference effects appearing for each pair of layers may be directly suppressed for a sufficiently large pump bandwidth. Our results provide insights and strategies that could guide practical implementations of QOCT.

description: In this paper, we studied the importance of indigenous biodiversity (native bush) on farm properties in the Waikato Region. To do this, we surveyed both real estate agents and farmers. We discovered that opinions of native bush between the two groups were very different. A small percentage of real estate agents believed that indigenous biodiversity on farms mattered; type of farm sold and age of respondent influenced this belief. While approximately half of Waikato farmers believed that native bush was important; this was influenced by age, income, education level, number of farm owners and sex. Farmers suggested that rates rebates, as well as subsidized planting and subsidized fencing would motivate them to plant more native bush on their lands.

description: Hendy and Kerr (2005b) find that an emissions charge on agricultural methane and nitrous oxide of $25 per tonne of carbon dioxide (CO2) equivalent would be likely to reduce New Zealand‘s net land-use related emissions for commitment period one in the order of 3%, with full accounting. The costs per farmer and as a percentage of profit would be very high. This paper considers the regional impacts of such a policy in New Zealand by allocating the emission charge across space according to the location of animals. We then combine our emissions charge information with data on the socio-economic characteristics of the affected areas. Obviously rural areas are heavily affected. In many respects, for example median income, ethnic mix, and percentage of working people with a university degree, the rural areas most affected have very similar socio-economic characteristics to other parts of rural New Zealand. Only in two ways do they appear to differ. Our findings indicate that areas with high emission costs tend to have high employment rates, but that they also have a disproportionately high number of unqualified people.

description: We investigate two kinds of coreless vortices with axisymmetric and nonaxisymmetric configurations in rotating two-component Bose-Einstein condensates. Starting from the Gross-Pitaevskii energy functional in a rotating frame, we derive a nonlinear sigma model generalized to the two-component condensates. In terms of a pseudospin representation, an axisymmetric vortex and a nonaxisymmetric one correspond to spin textures referred to as a "skyrmion" and a "meron-pair", respectively. A variational method is used to investigate the dependence of the sizes of the stable spin textures on system parameters, and the optimized variational function is found to reproduce well the numerical solution. In the SU(2) symmetric case, the optimal skyrmion and meron-pair are degenerate and transform to each other by a rotation of the pseudospin. An external rf-field that couples coherently the hyperfine states of two components breaks the degeneracy in favor of the meron-pair texture due to an effective transverse pseudomagnetic field. The difference between the intracomponent and intercomponent interactions yields a longitudinal pseudomagnetic field and a ferromagnetic or an antiferromagnetic pseudospin interaction, leading to a meron-pair texture with an anisotropic distribution of vorticity.

description: The connotation and development of circular economy and circular agriculture are illustrated from the perspective of circular economy. Take the duplicable Sino-Singapore Eco-City in Tianjin as a case to analyze the background, significance and features of building Sino-Singapore Tianjin Eco-City and point out the sustainable developmental orientation of the “three harmony and three capabilities” as well as its inspiration on the development of Tianjin urban agriculture from the aspects of water-saving, land-saving and energy-saving. Under the direction of circular economy theory, the enhancement of economical utilization of agricultural resources and resource utilization of agricultural wastes has positive effects on improving urban environment: decentralize organic solid wastes from sewage cycle system; further study the physiological and biochemical mechanism of increasing yield and income of ecological agriculture; bring urban agriculture into city land utilization planning and city development planning.
Modelling and mapping trophic overlap between fisheries and the world’s seabirds

Publisher: name: University of British Columbia

description: Seabird food consumption may reveal the potential for competition between seabirds and fisheries. I ndeed, coexistence of foraging seabirds and operating fisheries inevitably results in interactions, one of which is competition for the same resources. I used GIS-based modelling at a scale of 30-min spatial cells to: (a) map the foraging distribution of seabirds; (b) predict their annual food consumption rates in a spatially-explicit manner; and (c) estimate a spatially-explicit seabird - fisheries overlap index. Information on the population size, diet composition and foraging attributes of 351 species of seabirds was compiled into a Microsoft Access database. Trophic levels, expressing the position of seabirds in the marine ecosystem, were estimated for each species using diet composition data. Global annual food consumption by seabirds was estimated to be 96.4 million tonnes (95% CI: 78.0 to 114.7 million tonnes), compared to a total catch of nearly 120 million tonnes by all fisheries. Krill and cephalopods comprised over 58% of the overall food consumed and fishes most of the remainder. The families Procellariidae (albatrosses, petrels, shearwaters, etc.) and Spheniscidae (penguins) were responsible for more than 54% of the overall food consumption. Mapping the foraging distribution of seabirds revealed that, areas near New Zealand, the eastern coast of Australia, and the sub-Antarctic islands have high seabird species richness. Hawaii and the Caribbean were the only areas north of the equator with high species richness. Temperate and polar regions supported high densities of seabirds, and most food extracted by seabirds originated there. In addition, maps of the annual food consumption rates revealed that most of the food consumed by seabirds was extracted from offshore waters rather than nearshore ones, and from areas where overlap between seabirds and fisheries was low. My trophic overlap maps identified 'hotspots' of highest potential for conflict between fisheries and seabirds. Thus, this study may provide useful insight when developing management approaches to manage marine conservation areas.

description: Model-based evaluation of real time control and model predictive control strategies is often performed by estimating the yearly reduction in combined sewer overflow (CSO) volumes. This requires sufficiently long data series, but the necessary input data are often lacking in the case of complex control strategies. This article compares a new method to extrapolate yearly CSO volume reduction by simulating a limited number of CSO events. The method showed a good accuracy (2–3% deviation) when applied to a synthetic example. When applied to a real case study in Copenhagen (Denmark), the method showed a tendency to overestimate the performance of the control. The results underline how performance of real time control strategies is strongly affected by yearly variation, non-linearity and interactions among the elements of the system. It is thus suggested to use a mix of different performance indicators when evaluating control performance in conditions of data scarcity.
A different kind of quantum search

description: The quantum search algorithm consists of an alternating sequence of selective inversions and diffusion type operations, as a result of which it can find a target state in an unsorted database of size N in only sqrt(N) queries. This paper shows that by replacing the selective inversions by selective phase shifts of Pi/3, the algorithm gets transformed into something similar to a classical search algorithm. Just like classical search algorithms this algorithm has a fixed point in state-space toward which it preferentially converges. In contrast, the original quantum search algorithm moves uniformly in a two-dimensional state space. This feature leads to robust search algorithms and also to conceptually new schemes for error correction.

description: Through description of three-steps characteristic of dual economic theory and its practical significance to the process of industrialization and urbanization in China, and making comparative analysis between important criterion of "Lewis turning point" and current situation of rural surplus labors market in China, we can find that there exists a great deal of surplus labors in rural areas in our country, improvement of peasant income is the result of external interference of government, and demographic dividend in our country hasn’t finished. These phenomena go against the theory of "Lewis turning point". So it can prove that "Lewis turning point" in China hasn’t come yet. The paper points out the major factors of coexistence of “migrant workers scarcity” and labors redundancy in our country. The first one is structure contradiction of labors market; the second one is law of supply-demand of labors market; the third one is institutional barrier which hinders labors in free flow of census register and social guarantee. Therefore, if we want to realize successful transfer of rural surplus labors and the goal of industrialization and urbanization, we must promote upgrading of industrial structure, change the style of economic growth and realize harmonious development of regional economy in macrocosmic level; And in microcosmic level, we should eliminate institutional barrier which hinders transfer of rural surplus labors.

By using the Roiban-Siegel formulation of the superstring on the AdS_5 x S^5, we carefully treat the Wess-Zumino term and the constraint conditions intrinsic to the supersymmetric case, and construct explicitly non-local charges for a hidden infinite-dimensional symmetry. The existence of the symmetry is shown by Bena-Polchinski-Roiban. Then the super Yangian algebra is calculated. We also show the Serre relation ensuring the structure of the Hopf algebra. In addition, the classical integrability is discussed by constructing the Lax pair and the transfer matrix.

description: Based on the introduction of the connotation of “lemon market” and the phenomenon of “lemon” in the market of agricultural products, the consumers’ behaviors in the “lemon market” of agricultural products are analyzed. Firstly, consumers feel unfair in their minds in the process of negotiation; secondly, the purchase decision rule tends to be simplified in the “lemon market” of agricultural products; thirdly, the consumers tend to follow the masses in the “lemon market” of agricultural products. The economics significance of the impact of “lemon dilemma” of agricultural products on consumers is analyzed. The causes of the impact are analyzed from two aspects the uncertainty of collecting the information of agricultural information and the uncertainty of using the agricultural information. The suggestions and countermeasures are put forward in order to solve the “lemon” problems in agricultural market. In the first place, the excellent mechanism for producing the information of agricultural products should be constructed; in the second place, the government should encourage the multi-channel, multi-form and multi- level operation mode of agricultural products, to promote the optimization of market functions; in the third place, the government should widen the channel of information dissemination for agricultural products and establish the high efficiency feedback path; in the fourth place, the traditional thought pattern of consumers should be changed, so as to promote the healthy, orderly and benign development of agricultural products market.

description: We present simple and predictive realizations of neutrino masses in theories based on the $SU(6)$ grand unifying group. At the level of the lowest-dimension operators, this class of models predicts a skew-symmetric flavor structure for the Dirac mass term of the neutrinos. In the case that neutrinos are Dirac particles, the lowest-order prediction of this construction is then one massless neutrino and two degenerate massive neutrinos. Higher-dimensional operators suppressed by the Planck scale perturb this spectrum, allowing a good fit to the observed neutrino mass matrix. A firm prediction of this construction is an inverted neutrino mass spectrum with the lightest neutrino hierarchically lighter than the other two, so that the sum of neutrino masses lies close to the lower bound for an inverted hierarchy. In the alternate case that neutrinos are Majorana particles, the mass spectrum can be either normal or inverted. However, the lightest neutrino is once again hierarchically lighter than the other two, so that the sum of neutrino masses is predicted to lie close to the corresponding lower bound for the normal or inverted hierarchy. Near future cosmological measurements will be able to test the predictions of this scenario for the sum of neutrino masses. In the case of Majorana neutrinos that exhibit an inverted hierarchy, future neutrinoless double beta experiments can provide a complementary probe.

description: This study was conducted to evaluate the quality of drinking water in 28 homes of Merida and 7 municipalities of its Metropolitan Zone, in Yucatan, Mexico. The organochlorine pesticides (OCP) were investigated since it represents important health risks. The karst groundwater in Yucatan is vulnerable due to the easy infiltration of contaminants. The use of prohibited OCP in agriculture and livestock production as well as the minimal infrastructure for drinking water sanitation also pose important public health risks. Samples were analyzed by GC-ECD. The concentrations of lindane (0.01896 ppm), heptachlor (0.09741 ppm), endosulfan (0.05796 ppm), DDT (0.00519 ppm), and endrin (0.00125 ppm) were above the international standards. Samples were analyzed for physicochemical parameters such as pH, electrical conductivity, CaCO3, MgCO3, hardness, Na+, K+, SO4˭, and Cl−. Total hardness (405–646 mg/L) were above of international criterion. Adequate infrastructure to obtain safe drinking water for human consumption is strongly recommended.

description: H1N1 flu has been a widespread catastrophe emerging notoriously the past decade. This study is focused on evaluating the possible role of natural antioxidants as sialic acid adding moeities which could help in alleviating the flu attack. Ten different natural antioxidant compounds were the focus of the study. Molecular docking was performed to understand the binding interactions. Further validation was done by fast simulation to predict the protein structure fluctuations. From the fluctuation plots of chain A, B, C and D, we observe that India HA has predominant interactions. The small molecules that could help lessen the incidence of H1N1 flu are cathecin, andrographolide, biacalin, curcumin and eugenol. Andrographolide is the most important one. Further animal studies would help validate these findings further.

description: The double copy relates scattering amplitudes and classical solutions in Yang-Mills theory, gravity, and related field theories. Previous work has shown that this has an explicit realisation in self-dual YM theory, where the equation of motion can be written in a form that maps directly to Plebański's heavenly equation for self-dual gravity. The self-dual YM equation involves an area-preserving diffeomorphism algebra, two copies of which appear in the heavenly equation. In this paper, we show that this construction is a special case of a wider family of heavenly-type examples, by (i) performing Moyal deformations, and (ii) replacing the area-preserving diffeomorphisms with a less restricted algebra. As a result, we obtain a double-copy interpretation for hyper-Hermitian manifolds, extending the previously known hyper-Kähler case. We also introduce a double-Moyal deformation of the heavenly equation. The examples where the construction of Lax pairs is possible are manifestly consistent with Ward's conjecture, and suggest that the classical integrability of the gravity-type theory may be guaranteed in general by the integrability of at least one of two gauge-theory-type single copies.

description: The status quo of the violation of migrant workers’ interests is analyzed, the results are not so optimistic. The overall situation of migrant workers’ training rights is poor; migrant workers ’rights to enjoy legal holiday are seriously violated; the working conditions and health protection measures are weak; migrant workers’ rights to get legal payment are damaged to a different degree; the social security mechanism for migrant workers is imperfect and there are still large gap between supply and demand. Combining with the relevant theories of Game theory, migrant workers’ interests obtained under the situation of entering right protection organizations and do not entering the organizations are analyzed, the results show that entering right protection organizations is reasonable choice. The positive functions played by the improvement of the reputation of labor union in solving the problems of right protection are proved from the perspective of the Game Theory. Through the analysis on the operational effects of the right protection organizations of migrant workers, it can be detected that the functions of organizations owned by migrant workers themselves is mediocre but the labor union plays an important role in migrant workers’ right protection. The protection of migrant workers’ interests tends to legalization, so in order to further perfect the right protection of labor union, the labor union should legalize the protection of migrant workers rights and the specific measures on improving the reputation of labor union are put forward.

description: Reflection of the rise f agro-food production costs is analyzed based on the introduction of the quality safety situation of agricultural products in China . Firstly, rise of production cost caused by the demarcation of prohibited areas; secondly, rise of production cost caused by using environment-friendly agricultural inputs; thirdly, rise of production cost caused by quality control; rise of production cost caused by product certification. The ecological compensation mechanism which is beneficial to agro-food quality safety is set up according to the principle “the one who is benefited compensates”. Firstly, laws and regulations of agricultural production compensation are to be actively perfected. Secondly, experience of developed countries can be borrowed to establish a fiscal transfer payment system of production compensation. Thirdly, ecological agriculture is to be developed to produce products with safety and high quality. Since agro-ecological compensation can make up for the cost paid for protecting agro-ecological environment and producing safe agro-products by agro-food producers, and is beneficial to arousing producers’ motivation, compensation is made for agriculture producers from compensation objects, compensation scope and compensation mechanism to improve the quality safety level of agricultural products.

description: The grey forecast and the sustainable use evaluation are conducted on the data of farmland resources from 2010 to 2020 in Pingingshan City by using the area of farmland land from 1999 to 2010 and by applying the gray forecast and land pressure system. The results show that from 2010 to 2020 the quantity of farmland resources maintains balance; the minimum per capita farmland in Pingdinshan stays around the lower limit of per capita amount of farmland in China; the pressure of farmland is rather huge and the farmland protection is not so optimistic. Therefore, in order to realize the sustainable use of land resources in Pingdinshan City, the government should try to improve the efficiency of farmland use and implement stricter land protection system. as well as the requisition-compensation balance of farmland resources, land consolidation and land reclaimation and so on.

description: The nonlocal electrodynamics of uniformly rotating systems is presented and its predictions are discussed. In this case, due to paucity of experimental data, the nonlocal theory cannot be directly confronted with observation at present. The approach adopted here is therefore based on the correspondence principle: the nonrelativistic quantum physics of electrons in circular "orbits" is studied. The helicity dependence of the photoeffect from the circular states of atomic hydrogen is explored as well as the resonant absorption of a photon by an electron in a circular "orbit" about a uniform magnetic field. Qualitative agreement of the predictions of the classical nonlocal electrodynamics with quantum-mechanical results is demonstrated in the correspondence regime.

description: Self Interacting Wave Field (SIWF) theory replaces the ’probability wave’ interpretation of quantum mechanics with a mass-density one. It postulates the existence of a universal acoustic wave-bearing medium in Absolute Euclidian Space Time (AEST). Places where monochromatic waves arrive with phase and direction correlated have angular momentum and are called Field Rotators (FRs). Any non-linearity at FRs makes interaction between ’structures’ of FRs possible. Fundamental particles of nature arise from stable structures: where radiative losses are balanced against gains from resonance with a stochastic field within the medium. ’Phase Harmony’ within the structures has Special Relativity as a consequence. The de Broglie-Einstein equations hold if FRs rotate at the Compton frequency. Schrodinger’s wave function is shown to be a partial representation of the physical wave characterizing the motion of structures. Orbital and spin angular momenta are predicted to be ¯h and ¯h/2 respectively. The Pauli Exclusion principle is demonstrated. When applied to a 1-dimensional Simple Harmonic Oscillator and various square well potentials, the predicted eigenfunctions replicate those found via the Schrodinger equation. Eigenenergies also match if a dimensionless fractional parameter, α, is set to 1/π. In 3-D this could relate to the Fine Structure Constant.

description: Cocoa beans from the tropical tree crop, cacao (Theobroma cacao L.) is the main ingredient in chocolates, cocoa-based confectionaries, beverages, alcohol, cosmetics and nutraceuticals. There is considerable genetic diversity within the species that falls into 10 genetic clades. The diversity is centred in the Amazonian tropics with the greatest diversity observed in populations from Peru, Bolivia, Brazil, Ecuador and Colombia. Climate change poses an important challenge to agriculture, globally, characterised by increased carbon dioxide, elevated temperature and scarcity of rainfall or changes in the rainfall pattern resulting in severe drought. Flowering time and pod development period are important physiological traits associated with geographical adaptation. Although these traits are genetically determined, very little is known regarding the genetic variation for those traits in cocoa and its populations. The presence of representative accessions from the 10 genetic groups as well asvarious geographical populations of cocoa at a single location (International Cocoa Gene Bank, Centeno, Trinidad (ICGT)), allows for a comprehensive study of genetic diversity for flowering time and pod development period without the complication of environmental influences. The study was conducted during the period April to March over two consecutive years (2016-2017 and 2017-2018) with a minimum of 10 accessions from each genetic group and from three hybrid populations. Three trees were selected and labelled and the flowering times noted. From each accession 20 flowers were tagged, and successful pod sets determined after 7 days. At least 10 pods from each accession were followed to maturity with pod length and width measurements taken at fortnightly intervals. At pod maturity the pod dimensions, the number of beans and bean size, bean weight (10 beans-fresh and dry) were determined. This study will help to understand the genetic variation for flowering time and pod development period among the geographical populations of cocoa. It will also help to understand the relationships among the various traits studied. Together this information along with geographical information could provide interesting insights into the evolutionary mechanisms that govern flowering time and pod development period, which in the future will be useful in developing accessions for climate change adaptation. 
KEY WORDS: climate resilience, genetic variation, pod maturity, average pod growth rate, pod index.

description: Authentication schemes are practised globally to verify the legitimacy of users and servers for the exchange of data in different facilities. Generally, the server verifies a user to provide resources for different purposes. But due to the large network system, the authentication process has become complex and therefore, time-to-time different authentication protocols have been proposed for the multi-server architecture. However, most of the protocols are vulnerable to various security attacks and their performance is not efficient. In this paper, we propose a secure and energy-efficient remote user authentication protocol for multi-server systems. The results show that the proposed protocol is comparatively ~44% more efficient and needs ~38% less communication cost. We also demonstrate that with only two-factor authentication, the proposed protocol is more secure from the earlier related authentication schemes.

description: Based on the research technology of scholars’ prediction of farmers’ income and the data of per capita annual net income in rural households in Henan Statistical Yearbook from 1979 to 2009, it is found that time series of farmers’ income is in accordance with I(2) non-stationary process. The order-determination and identification of the model are achieved by adopting the correlogram-based analytical method of Box-Jenkins. On the basis of comparing a group of model properties with different parameters, model ARIMA (4, 2, 2) is built up. The testing result shows that the residual error of the selected model is white noise and accords with the normal distribution, which can be used to predict farmers’ income. The model prediction indicates that income in rural households will continue to increase from 2009 to 2012 and will reach the value of 2 282.4, 2 502.9, 2 686.9 and 2 884.5 respectively. The growth speed will go down from fast to slow with weak sustainability.

description: According to the data in 1990-2009 Huai’an Statistical Yearbook and Jiangsu Statistical Yearbook, production structure of agriculture in Huai’an City is analyzed. Result shows that economic efficiency of planting industry is significantly lower than that of other industry types of agriculture; and the production structure of agriculture in Huai’an City is unbalanced and needs further optimization. The reasons for the imbalance in industrial structure are various, such as the relatively low quality of agricultural employees, the backward marketing of planting, and the lack of standardization management. Finally, corresponding suggestions are put forward, including developing education, conducting vocational training, improving the human capital stock of Huai’an City, cultivating the leading enterprises for agricultural product processing, and realizing the scale agglomeration effect of agricultural production in planting industry.

description: One of the obstacles in the search for exoplanets via transits is the large number of candidates that must be followed up, few of which ultimately prove to be exoplanets. Any method that could make this process more efficient by somehow identifying the best candidates and eliminating the worst would therefore be very useful. Seager and Mallen-Ornelas (2003) demonstrated that it was possible to discern between blends and exoplanets using only the photometric characteristics of the transits. However, these techniques are critically dependent on the shape of the transit, characterization of which requires very high precision photometry of a sort that is atypical for candidates identified from transit searches. We present a method relying only on transit duration, depth, and period, which require much less precise photometry to determine accurately. The numerical tool we derive, the exoplanet diagnostic η, is intended to identify the subset of candidates from a transit search that is most likely to contain exoplanets, and thus most worthy of subsequent follow-up studies. The effectiveness of the diagnostic is demonstrated with its success in separating modeled exoplanetary transits and interlopers, and by applying it to actual OGLE transit candidates.
