description: This study analyses the effect of international factors on the South African agricultural market and prices through a case study of the wheat industry. Firstly, a review of the international wheat market is given with the accent on support to wheat industries elsewhere in the world and the effects of support on world prices, domestic prices and production. This is followed by an explanation of the implications of GAIT and specifically trade liberalisation on South African agricultural prices, especially that of wheat. Results show that the average world prices of agricultural commodities in general will increase by 22 per cent if industrial countries discontinue all support to agricultural producers. This also represents the distortion effect of these measures.

description: A finite-temperature many-body perturbation theory is presented that expands in power series the electronic grand potential, chemical potential, internal energy, and entropy on an equal footing. Sum-over-states and sum-over-orbitals analytical formulas for the second-order perturbation corrections to these thermodynamic properties are obtained in a time-independent, nondiagrammatic, algebraic derivation, relying on the sum rules of the Hirschfelder-Certain degenerate perturbation energies in a degenerate subspace as well as nine algebraic identities for zeroth-order thermal averages of one- through four-indexed quantities and of products thereof. They reproduce numerically exactly the benchmark data obtained as the numerical derivatives of the thermal-full-configuration-interaction results for a wide range of temperature.

description: An integrated farm planning approach was applied in the Kroonstad area during the early 1980's to promote farming efficiency. Using linear programming, 29 farm plans were developed. Two years after completion of the last plan a research project was conducted to determine the extent of plan implementation; reasons for deviations from planning proposals; and guidelines for future planning endeavours. This research note reports the findings of this research.

description: We argue that Josephson junction networks may be engineered to allow for the emergence of new and robust quantum coherent states. We provide a rather intuitive argument showing how the change in topology may affect the quantum properties of a bosonic particle hopping on a network. As a paradigmatic example, we analyze in detail the quantum and thermodynamic properties of non-interacting bosons hopping on a comb graph. We show how to explicitly compute the inhomogeneities in the distribution of bosons along the comb's fingers, evidencing the effects of the topology induced spatial Bose-Einstein condensation characteristic of the system. We propose an experiment enabling to detect the spatial Bose-Einstein condensation for Josephson networks built on comb graphs.

description: Improvements beyond the primitive approximation in the path integral Monte Carlo method are explored both in a model problem and in real systems. Two different strategies are studied: the Richardson extrapolation on top of the path integral Monte Carlo data and the Takahashi-Imada action. The Richardson extrapolation, mainly combined with the primitive action, always reduces the number-of-beads dependence, helps in determining the approach to the dominant power law behavior, and all without additional computational cost. The Takahashi-Imada action has been tested in two hard-core interacting quantum liquids at low temperature. The results obtained show that the fourth-order behavior near the asymptote is conserved, and that the use of this improved action reduces the computing time with respect to the primitive approximation.

description: We present results of numerical simulations for pure U(1) gauge theory in a non-commutative space. The theory is mapped onto a dimensionally reduced matrix model, which renders its numerical treatment feasible. New data on large lattices reveal the scaling of Wilson loops and their correlation functions in the simultaneous limit to the continuum and to infinite volume, at fixed non-commutativity. In this on-going project we are particularly interested in the IR behaviour, the ``photo-ball'' spectrum and in the photon dispersion relation.

 Remarks: The present material confirms the occurrence of Typton prionurus in the southwestern Atlantic (Brazil). The single previous record of T. prionurus from off Pará by Bullis & Thompson (1965) remains doubtful as it was listed as “ Typton prionurus Holthuis?”, with no further remarks, illustrations or indication of where the corresponding material was deposited. Bullis & Thompson’s (1965) record was apparently overlooked by Vieira et al. (2012), although it was listed in an earlier checklist of Coelho et al. (2006). We found no noticeable difference between the present material of T. prionurus (Fig. 1) and Holthuis’ (1951) description and figures. The species may be readily distinguished from its West Atlantic congeners by the serrate distolateral margin of the uropodal exopod (Fig. 1 m).

description: The patent database is often used in searches of inspirational stimuli for innovative design opportunities because of its large size, extensive variety and rich design information in patent documents. However, most patent mining research only focuses on textual information and ignores visual information. Herein, we propose a convolutional neural network (CNN)-based patent image retrieval method. The core of this approach is a novel neural network architecture named Dual-VGG that is aimed to accomplish two tasks: visual material type prediction and international patent classification (IPC) class label prediction. In turn, the trained neural network provides the deep features in the image embedding vectors that can be utilized for patent image retrieval and visual mapping. The accuracy of both training tasks and patent image embedding space are evaluated to show the performance of our model. This approach is also illustrated in a case study of robot arm design retrieval. Compared to traditional keyword-based searching and Google image searching, the proposed method discovers more useful visual information for engineering design.

description: We solve the master equations of two charged qubits measured by two serially coupled quantum point contacts (QPCs). We describe two-qubit dynamics by comparing entangled states with product states, and show that the QPC current can be used for reading out results of quantum calculations and providing evidences of two-qubit entanglement. We also calculate the concurrence of the two qubits as a function of dephasing rate that originates from the measurement. We conclude that coupled charge qubits can be effectively detected by a QPC-based detector.

description: A very small fraction of (runaway) massive stars have masses exceeding $60$-$70\, \rm M_{\odot}$ and are predicted to evolve as Luminous-Blue-Variable and Wolf-Rayet stars before ending their lives as core-collapse supernovae. Our 2D axisymmetric hydrodynamical simulations explore how a fast wind ($2000\, \rm km\, \rm s^{-1}$) and high mass-loss rate ($10^{-5}\, \rm M_{\odot}\, \rm yr^{-1}$) can impact the morphology of the circumstellar medium. It is shaped as 100 pc-scale wind nebula which can be pierced by the driving star when it supersonically moves with velocity $20$-$40\, \rm km\, \rm s^{-1}$ through the interstellar medium (ISM) in the Galactic plane. The motion of such runaway stars displaces the position of the supernova explosion out of their bow shock nebula, imposing asymmetries to the eventual shock wave expansion and engendering Cygnus-loop-like supernova remnants. We conclude that the size (up to more than $200\, \rm pc$) of the filamentary wind cavity in which the chemically enriched supernova ejecta expand, mixing efficiently the wind and ISM materials by at least $10\%$ in number density, can be used as a tracer of the runaway nature of the very massive progenitors of such $0.1\, \rm Myr$ old remnants. Our results motivate further observational campaigns devoted to the bow shock of the very massive stars BD+43 3654 and to the close surroundings of the synchrotron-emitting Wolf-Rayet shell G2.4+1.4.

description: This study investigated the reduction of hexavalent chromium (Cr(VI)) with sulfur dioxide (SO2) and adsorption of Cr(VI) onto dried grape pulp carbonized with sulfuric acid. Cr(VI) reduction capacities of SO2 were determined. The filtrate was titrated with NaOH solution after shaking and filtering the carbonized material to retain unreacted sulfuric acid (H2SO4). Simple washing recovered 25–38% of the experimental acid at low concentrations. The carbonized material was washed twice with distilled water and then dried at 105 °C and weighed. The carbonized material had a yield of 56.6% (grape pulp/sulfuric acid ratios of 1:2), and the lower the H2SO4 content, the better the yield, suggesting that the higher the acid content, the lower the Cr(VI) content per unit grape pulp. Cr(VI) reduction capacities were 219.5, 195.3, and 190.9 mg Cr(VI)/g-H2SO4 for the grape pulp/sulfuric acid ratios of 1:1, 1:2, and 1:3, respectively. Novelty statement: A carbonaceous material was obtained from grape pulp by carbonizing with concentrated sulfuric acid. The main objective of this study was to evaluate gas, liquid, and solid products or co-products obtained during carbonization process for hexavalent chromium treatment in aqueous solutions. In this context, (a) hexavalent chromium reduction capability of the gas evolved during carbonization was determined, (b) characterization of unreacted acid recovered by washing the carbonized product left after carbonization step was done, (c) carbonaceous adsorbent obtained was characterized and (d) hexavalent chromium adsorption characteristics of carbonaceous material obtained was determined.HIGHLIGHTSReduction and adsorption mechanisms of hexavalent chromium were investigated.A waste recycling method was proposed.The effects of sulfuric acid on carbonization were assessed.The structures and chemical compositions of a carbonized material were evaluated.The carbonized material is a cost-effective porous adsorbent for a clean environment.

description: The entanglement of multi-atom quantum states is considered. In order to cancel noise due to inhomogeneous light atom coupling, the concept of matched multi-atom observables is proposed. As a means to eliminate an important form of decoherence this idea should be of broad relevance for quantum information processing with atomic ensembles. The general approach is illustrated on the example of rotation angle measurement, and it is shown that the multi-atom states that were thought to be only weakly entangled can exhibit near-maximum entanglement.

description: Meissner fraction in the superconducting state of lead archaeological artifacts is used to evaluate the mass of the uncorroded metal in the sample. Knowing the total mass of the sample the mass of all corrosion products is established. It is shown that this mass correlates with the archaeological age of the lead artifacts over a time span of ~2500 years. Well-dated untreated lead samples from Tel-Dor, the Persian period, Caesarea, the Byzantine and the Crusader periods as well as contemporary data were used to establish the dating correlation. This new chemical dating method is apparently applicable to lead artifacts buried in soils with the pH>6.5. In such soils the corrosion process is very slow and the corrosion products, mainly PbO and PbCO3, accumulate over hundreds of years. The method presented is in principle non-destructive.

description: This case study is designed to explore the process of implementation of co curricular management at secondary schools among 10 teachers who are involved as a group of co-curricular management in two states Kuala Lumpur and Selangor. This study was implemented based on management theories Stoner, Freedmen and Gilbert (1995) and also Gulick’s principle of management (1954) with minor alterations to fit the study needs. This qualitative study utilized the constant comparison method for data analysis. Data were obtained from three techniques which are in-depth interview, observation and document analysis.Participant selection was based on purposive sampling methods, in order to facilitate an in-depth understanding of the phenomenon in question. The analysis and data collection process was conducted simultaneously and continuously until data saturation was achieved. The results of the research show that all participants have given their opinions about the implementation and also the process of co-curricular management at the secondary school. Generally, this study shows that co-curricular management used four aspects to manage co-curricular activities at school in order to maintain the excellence of co-curricular programs. The five aspects are: planning, organizing, leadership, control and community involvement.

description: Asymmetric spectral line shapes are a hallmark of interference of a quasi-bound state with a continuum of states. Such line shapes are well known for multichannel systems, for example, in photoionization or Feshbach resonances in molecular scattering. On the other hand, in resonant single channel scattering, the signature of such interference may disappear due to the orthogonality of partial waves. Here, we show that probing the angular dependence of the cross section allows us to unveil asymmetric Fano profiles also in a single channel shape resonance. We observe a shift in the peak of the resonance profile in the elastic collisions between metastable helium and deuterium molecules with detection angle, in excellent agreement with theoretical predictions from full quantum scattering calculations. Using a model description for the partial wave interference, we can disentangle the resonant and background contributions and extract the relative phase responsible for the characteristic Fano-like profiles from our experimental measurements.
Relation between widths of proton resonances and neutron asymptotic normalization coefficients in mirror states of light nuclei in a microscopic cluster model

description: It has been suggested recently ({\it Phys. Rev. Lett.} 91, 232501 (2003)) that the widths of narrow proton resonances are related to neutron Asymptotic Normalization Coefficients (ANCs) of their bound mirror analogs because of charge symmetry of nucleon-nucleon interactions. This relation is approximated by a simple analytical formula which involves proton resonance energies, neutron separation energies, charges of residual nuclei and the range of their strong interaction with the last nucleon. In the present paper, we perform microscopic-cluster model calculations for the ratio of proton widths to neutron ANCs squared in mirror states for several light nuclei. We compare them to predictions of the analytical formula and to estimates made within a single-particle potential model. A knowledge of this ratio can be used to predict unknown proton widths for very narrow low-lying resonances in the neutron-deficient region of the $sd$- and $pf$-shells, which is important for understanding the nucleosynthesis in the $rp$-process.

description: The important role played by women and the potential to fulfil an even greater role, has been overlooked to a large extent in South Africa. Although there are numerous organisations and projects aimed at development at rural and community level - from development in small scale family enterprises to larger commercial enterprises to professional and leadership positions - very little attention has been payed to the role of the woman and the enhancement thereof. An awareness of the importance of development of women has started to surface, and more is been done to accommodate women and raise them to the level they deserve. Women's perception of themselves are changing, and they are venturing beyond traditional female boundaries. They must however be afforded the chance to develop and have equal access to opportunities at all levels in the South African society

description: Due to the efforts by numerous ground-based surveys and NASA's Kepler and TESS, there will be hundreds, if not thousands, of transiting exoplanets ideal for atmospheric characterization via spectroscopy with large platforms such as JWST and ARIEL. However their next predicted mid-transit time could become so increasingly uncertain over time that significant overhead would be required to ensure the detection of the entire transit. As a result, follow-up observations to characterize these exoplanetary atmospheres would require less-efficient use of an observatory's time---which is an issue for large platforms where minimizing observing overheads is a necessity. Here we demonstrate the power of citizen scientists operating smaller observatories ($\le$1-m) to keep ephemerides "fresh", defined here as when the 1$σ$ uncertainty in the mid-transit time is less than half the transit duration. We advocate for the creation of a community-wide effort to perform ephemeris maintenance on transiting exoplanets by citizen scientists. Such observations can be conducted with even a 6-inch telescope, which has the potential to save up to $\sim$10,000~days for a 1000-planet survey. Based on a preliminary analysis of 14 transits from a single 6-inch MicroObservatory telescope, we empirically estimate the ability of small telescopes to benefit the community. Observations with a small-telescope network operated by citizen scientists are capable of resolving stellar blends to within 5''/pixel, can follow-up long period transits in short-baseline TESS fields, monitor epoch-to-epoch stellar variability at a precision 0.67\%$\pm$0.12\% for a 11.3 V-mag star, and search for new planets or constrain the masses of known planets with transit timing variations greater than two minutes.

The provision of a livestock marketing system was aimed at giving farmers satisfactory returns for their animals. This has not increased the turnover of livestock among the farmers, despite farmers stating that they keep livestock as a source of income. The major drawback to farmers more fully utilising the marketing facilities is that the majority of the households have insufficient livestock to meet their social and cultural needs and to have animals to sell on a regular basis.

description: The aim of this study is to investigate the effect of behavioural parent training on parents’ verbalisation in reducing disruptive behaviours among preschool children with ADHD. There were three children diagnosed with ADHD-Combined (ADHD-C), two children with ADHD-Hyperactivity Impulsivity (ADHD-HI), and one child with ADHD-Inattentive (ADHD-I) involved in the study. Parent-Child Interaction Therapy (PCIT) is one of the promising behavioural parent training programmes has been employed in the study. By employing the PCIT, the pattern of changes in two main variables, parent’s verbalisation and child disruptive behaviours in two different parenting skills, Child Directed Interaction (CDI) and Parent Directed Interaction (PDI) were observed and coded. The A-B single-case experimental design was applied to systematically test the effect of PCIT intervention on targeted variables throughout four different phases: Baseline (A1), Intensive Treatment (B-IT), Maintenance Treatment (B-MT) and Follow-up (F1). The pre-test and post-test assessments conducted were using Eyberg Child Behaviour Inventory (ECBI), Daily Parent Observation (DPO) to measure disruptive behaviour, and Dyadic Parent-Child Interaction Coding System (DPICS) to measure parent’s verbalisation. It found that when parents showed some improvement in their verbalisation, the children scores showed below clinical cut-off points on measures for disruptive behaviours. Therefore, the findings indicated that PCIT was effective in increasing parent’s proficiency in using positive verbalisation (praise, reflections and behavioural descriptions) and reducing their negative verbalisation (commands, questions, and criticism) when interacting with their child.

description: Background Members of the genus Arcobacter are considered as emerging zoonotic food and waterborne pathogens that cause gastroenteritis and bacteremia in humans. However, the potential risk that Arcobacter species pose to public health remains unassessed in various countries, including Baltic states. Therefore, the aim of this study was to determine the prevalence, antimicrobial susceptibility and presence of putative virulence genes of Arcobacter isolates recovered from humans, food products and environmental water in Lithuania. Results A total of 1862 samples were collected and examined from 2018 to 2020 in the city of Kaunas. Overall, 11.2% (n = 208) of the samples were positive for the presence of Arcobacter spp. The highest prevalence was detected in chicken meat (36%), followed by environmental water (28.1%), raw cow milk (25%), ready-to-eat salad mixes (7.1%) and human stool (1.7%). A. butzleri was the most frequently isolated species (n = 192; 92.3%), followed by A. cryaerophilus (n = 16; 7.7%). Arcobacter spp. antimicrobial susceptibility testing revealed unimodally distributed aggregated minimal inhibitory concentrations (MICs) for gentamicin, tetracycline, ciprofloxacin, ampicillin and erythromycin. However, a bimodal distribution for azithromycin was found with 96.2% of determined MICs above the epidemiological cut-off value (ECOFF) defined for Campylobacter jejuni (0.25 µg/ml). Majority of the Arcobacter isolates (n = 187; 89.9%) showed high susceptibility to ciprofloxacin with MICs below or equal to the ECOFF value of 0.5 µg/ml. The putative virulence genes cadF (100%), ciaB (100%), cj1349 (99%), tlyA (99%), mviN (97.9%) and pldA (95.8%) were the predominant genes detected among A. butzleri isolates. In contrast, the mviN and ciaB genes were present in all, whereas cj1349 (12.5%), tlyA (25%) and hecA (12.5%) were only detected in few A. cryaerophilus isolates. Conclusions Our results demonstrate that food products and environmental water in Lithuania are frequently contaminated with Arcobacter spp. that carry multiple putative virulence genes. Furthermore, A. butzleri were isolated from 1.7% of inpatients. Fluoroquinolones and aminoglycosides were found to be more effective against Arcobacter in comparison to other antimicrobial agents. However, further studies are needed to determine the pathogenic mechanisms and factors that facilitate the spread of Arcobacter infections.

description: Micron-scale optical cavities are produced using a combination of template sphere self-assembly and electrochemical growth. Transmission measurements of the tunable microcavities show sharp resonant modes with a Q-factor>300, and 25-fold local enhancement of light intensity. The presence of transverse optical modes confirms the lateral confinement of photons. Calculations show sub-micron mode volumes are feasible. The small mode volume of these microcavities promises to lead to a wide range of applications in microlasers, atom optics, quantum information, biophotonics and single molecule detection.

description: The wheat industry in South Africa is mainly concentrated on the utilisation of the internal market and in view of future internal market development and expansion the internal market potential for wheat and wheat products are discussed in this article. Considering wheat's role as a staple food for a large part of the population, the purpose is to form an idea of the factors which may influence the future market potential for wheat and wheat products in South Africa. Such a strategic perspective can serve as a starting point for the planning and formulation of marketing strategies in the wheat industry

description: Utilizing the Pauli-blocking mechanism we show that shining circular polarized light on a singly-charged quantum dot induces spin dependent fluorescence. Employing the quantum-jump technique we demonstrate that this resonance luminescence, due to a spin dependent optical excitation, serves as an excellent readout mechanism for measuring the spin state of a single electron confined to a quantum dot.

description: Nano-Fourier-transform infrared spectroscopy (nano-FTIR) combines infrared spectroscopy with scanning probe microscopy (SPM) techniques and enables spectroscopic imaging of molecular and electronic properties of matter at nanometer spatial resolution. The spectroscopic imaging can be used to derive chemical mappings, i.e. the spatial distribution of concentrations of the species contained in a given sample. However, due to the sequential scanning principle underlying SPM, recording the complete spectrum over a large spatial area leads to long measurement times. Furthermore, the acquired spectrum often contains additional signals from species and lineshape effects that are not explicitly accounted for. A compressive chemical mapping approach is proposed for undersampled nano-FTIR data that utilizes sparsity of these additional signals in the spectral domain. The approach combines a projection technique with standard compressed sensing, followed by a spatially regularized regression. Using real nano-FTIR measurements superimposed by simulated interferograms representing the chemical mapping of the contained species, it is demonstrated that the proposed procedure performs well even in cases in which the simulated interferograms and the sparse additional signals exhibit a strong spectral overlap.
Branching annihilating random walks with long-range attraction in one dimension

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We introduce and numerically study the branching annihilating random walks with long-range attraction (BAWL). The long-range attraction makes hopping biased in such a manner that particle's hopping along the direction to the nearest particle has larger transition rate than hopping against the direction. Still, unlike the Lévy flight, a particle only hops to one of its nearest-neighbor sites. The strength of bias takes the form $x^{-σ}$ with non-negative $σ$, where $x$ is the distance to the nearest particle from a particle to hop. By extensive Monte Carlo simulations, we show that the critical decay exponent $δ$ varies continuously with $σ$ up to $σ=1$ and $δ$ is the same as the critical decay exponent of the directed Ising (DI) universality class for $σ\ge 1$. Investigating the behavior of the density in the absorbing phase, we argue that $σ=1$ is indeed the threshold that separates the DI and non-DI critical behavior. We also show by Monte Carlo simulations that branching bias with symmetric hopping exhibits the same critical behavior as the BAWL.

description: Cobb Douglas type production functions were fitted in order to evaluate agricultural productivity. The country was divided into five fairly homogeneous regions for this purpose. Agricultural productivity tended to improve between 1976 and 1988, but serious malallocations persist. Overmechanization has occurred in all but one region. Labour is underutilized and underpaid. The Karoo is overstocked with livestock.

description: In this paper, we have investigated the holographic entanglement entropy for a linear subsystem in a $3+1$-dimensional Lifshitz black hole. The entanglement entropy has been analysed in both the infra-red and ultra-violet limits, and has also been computed in the near horizon approximation. The notion of a generalized temperature in terms of the renormalized entanglement entropy has been introduced. This also leads to a generalized thermodynamics like law $E=T_g S_{REE}$. The generalized temperature has been defined in such a way that it reduces to the Hawking temperature in the infra-red limit. We have then computed the holographic subregion complexity. Then the Fisher information metric and the fidelity susceptibility for the same linear subsystem have also been computed using the bulk dual prescriptions. It has been observed that the two metrics are not related to each other.

description: We study the zero-temperature criticality of the Ising model on two-dimensional dynamical triangulations to contemplate its physics. As it turns out, an inhomogeneous nature of the system yields an interesting phase diagram and the physics at the zero temperature is quite sensitive about how we cool down the system. We show the existence of a continuous parameter that characterizes the way we approach the zero-temperature critical point and it may enter in a critical exponent.

description: The dynamic state index (DSI) is a scalar field that combines variational information on the total energy and vorticity of a flow field with the second law of thermodynamics. Its magnitude is a combined local measure for non-stationarity, diabaticity, and dissipation in the flow, and it has been shown to provide good qualitative indications for the onset and presence of precipitation and the organization of storms. The index has been derived thus far for ideal fluid models only, however, so that one may expect more detailed insights from a revised definition of the quantity that includes more complex aerothermodynamics. The present paper suggests definitions of DSI-like indicators for flows of moist air with phase changes and precipitation. In this way, the DSI is generalized to signal deviations from a variety of different types of balanced states. A comparison of these indices evaluated with respect to one and the same flow field enables the user to test whether the flow internally balances any combination of the physical processes encoded in the generalized DSI-indices.
