description: The system of agricultural cooperatives, collectively referred to as JA, is one of the most politically powerful organizations in Japanese politics. Based on its strong ties with the ruling Liberal Democratic Party, which has been in government for almost the entire postwar period, JA has lobbied the Japanese government to maintain its various restrictive trade policies regarding agricultural commodities. JA is regarded by many as being Japan’s biggest obstacle to further international trade liberalization. How has JA become so politically powerful, and will JA continue to dictate the position of the Japanese government in international trade negotiations? In order to provide clear answers to these questions, this study focuses on JA’s sociopolitical role and influence in rural communities.

description: This paper assesses the impact of the growth in the number of supermarkets in SADC countries. It uses a case-study approach in two countries-Botswana, and Zambia. Data was collected from 16 chain supermarkets and 42 local shops in Botswana and Zambia and 78 small-scale farmers who produce FFV for the market in Zambia in 2005 and 2007. A one-way analysis of variance was used to compare food product prices in supermarkets and local shops and a two-step impact model was used to determine the impact of supermarkets procurement on small-scale farmers. The results show that prices of processed food products were cheaper in supermarkets in Botswana and Zambia, implying that consumers gain from purchasing food products from chain supermarkets in case-study countries. Small-scale farmers who access chain supermarkets FFV supply chain in Zambia registered higher income compared to their counterparts who sold on the traditional market. The study concluded that participation in the supermarkets supply chains may impact positively on both consumers and small-scale farmers.

Art and design is still a gendered school subject

Subjects: gender

art-based careers

description: Gender disparity in the take-up of post-compulsory school art, leading to the predominance of girls at GCSE and A-level, appears to be linked to the perception that the subject offers few career prospects, and to the notion that boys dislike drawing and painting. This paper derives from a case study of a London secondary school art department during 2010/11. One aspect of the research examines the way art remains a feminine, marginalised subject despite its relevance to the increasingly successful creative industries. A central finding is that good attainment at GCSE still relies heavily on a demanding homework load and copious preparatory studies, both off-putting to students, particularly boys.

description: Two important features of agricultural quarantine inspections of shipping containers for invasive species at U.S. ports of entry are the general absence of economic considerations and the severe uncertainty that surrounds invasive species introductions. In this article, we propose and illustrate a method for determining an inspection monitoring protocol that addresses both issues. An inspection monitoring protocol is developed that is robust in maximizing the set of uncertain outcomes over which an economic performance criterion is achieved. The framework is applied to derive an alternative to Agricultural Quarantine Inspection (AQI) for shipments of fruits and vegetables as currently practiced at ports of entry in the United States.

description: We report on a study of the long-term stability and absolute accuracy of an atom interferometer gyroscope. This study included the implementation of an electro-optical technique to reverse the vector area of the interferometer for reduced systematics and a careful study of systematic phase shifts. Our data strongly suggests that drifts less than 96 $μ$deg/hr are possible after empirically removing shifts due to measured changes in temperature, laser intensity, and several other experimental parameters.

description: In 1936 Einstein predicted the phenomenon presently known as gravitational lensing (GL). A prime feature of GL is the magnification, because of the gravitational field, of the star visible surface as seen from a distant observer. We show here that nonlinear electrodynamics (NLED) modifies in a fundamental basis Einstein's general relativistic (GR) original derivation. The effect becomes apparent by studying the light propagation from a strongly magnetic ($B$) pulsar (SMP). Unlike its GR counterpart, the photon dynamics in NLED leads to a new effective GL, which depends also on the $B$-field permeating the pulsar. The apparent radius of a SMP appears then unexpectedly diminished, by a large factor, as compared to the classical Einstein's prediction. This may prove very crucial in determining physical properties of high $B$-field stars from their X-ray emission.

Stable and unstable attractors in Boolean networks

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: Boolean networks at the critical point have been a matter of debate for many years as, e.g., scaling of number of attractor with system size. Recently it was found that this number scales superpolynomially with system size, contrary to a common earlier expectation of sublinear scaling. We here point to the fact that these results are obtained using deterministic parallel update, where a large fraction of attractors in fact are an artifact of the updating scheme. This limits the significance of these results for biological systems where noise is omnipresent. We here take a fresh look at attractors in Boolean networks with the original motivation of simplified models for biological systems in mind. We test stability of attractors w.r.t. infinitesimal deviations from synchronous update and find that most attractors found under parallel update are artifacts arising from the synchronous clocking mode. The remaining fraction of attractors are stable against fluctuating response delays. For this subset of stable attractors we observe sublinear scaling of the number of attractors with system size.

description: We investigate the relative timing between hard X-ray (HXR) peaks and structures in metric and decimetric radio emissions of solar flares using data from the RHESSI and Phoenix-2 instruments. The radio events under consideration are predominantly classified as type III bursts, decimetric pulsations and patches. The RHESSI data are demodulated using special techniques appropriate for a Phoenix-2 temporal resolution of 0.1s. The absolute timing accuracy of the two instruments is found to be about 170 ms, and much better on the average. It is found that type III radio groups often coincide with enhanced HXR emission, but only a relatively small fraction ($\sim$ 20%) of the groups show close correlation on time scales $

Infinitesimally Nonlocal Lorentz Violation
Creators: name: Altschul, B.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We introduce a new Lorentz-violating modification to a scalar quantum field theory. This interaction, while super-renormalizable by power counting, is fundamentally different from the interactions previously considered within the Lorentz-violating standard model extension. The Lagrange density is nonlocal, because of the presence of a Hilbert transform term; however, this nonlocality is also very weak. The theory has reasonable stability and causality properties and, although the Lorentz-violating interaction possesses a single vector index, the theory is nonetheless CPT even. As an application, we analyze the possible effects of this new form of Lorentz violation on neutral meson oscillations. We find that under certain circumstances, the interaction may lead to quite peculiar sidereal modulations in the oscillation frequency.

description: It has been known that the uptake mechanisms of cell-penetrating peptides(CPPs) depend on the experimental conditions such as concentration of peptides, lipid composition, temperature, etc. In this study we investigate the temperature dependence of the penetration of Arg9s into a DOPC/DOPG(4:1) membrane using molecular dynamics(MD) simulations at two different temperatures, T = 310 K and T = 288 K. Although it is difficult to identify the temperature dependence because of having only one single simulation at each temperature and no evidence of translocation of Arg9s across the membrane at both temperatures, our simulations suggest that followings are strongly correlated with the penetration of Arg9s: a number of water molecules coordinated by Arg9s, electrostatic energy between Arg9s and the lipids molecules. We also present how Arg9s change a bending rigidity of the membrane and how a collective behavior between Arg9s enhances the penetration and the membrane bending. Our analyses can be applicable to any cell-penetrating peptides(CPPs) to investigate their interactions with various membranes using MD simulations.

description: We present an experimental and theoretical study of the high-energy excitation spectra of a dipolar supersolid. Using Bragg spectroscopy, we study the scattering response of the system to a high-energy probe, enabling measurements of the dynamic structure factor. We experimentally observe a continuous reduction of the response when tuning the contact interaction from an ordinary Bose-Einstein condensate to a supersolid state. Yet the observed reduction is faster than the one theoretically predicted by the Bogoliubov-de-Gennes theory. Based on an intuitive semi-analytic model and real-time simulations, we primarily attribute such a discrepancy to the out-of-equilibrium phase dynamics, which although not affecting the system global coherence, reduces its response.

Suppressing Leakage Magnetic Field in Wireless Power Transfer using Halbach Array-Based Resonators

description: Wireless power transfer has the potential to seamlessly power electronic systems, such as electric vehicles, industrial robots, and mobile devices. However, the leakage magnetic field is a critical bottleneck that limits the transferable power level, and heavy ferromagnetic shields are needed for transferring large amounts of power. In this paper, we propose a ferrite-less coil design that generates an asymmetric magnetic field pattern focused on one side of the resonator, which effectively reduces the leakage magnetic field. The key to enabling the asymmetric field pattern is a coil winding strategy inspired by the Halbach array, a permanent magnet arrangement, which is then tailored for wireless power using an evolutionary strategy algorithm. Numerical analyses and simulations demonstrated that the proposed coil structure delivers the same amount of power as spiral coils, while achieving an 86.6% reduction in magnetic field intensity at a plane located 75 mm away from the resonator pair and a power efficiency of 96.0%. We verified our approach by measuring the power efficiency and magnetic field intensity of a test wireless power system operating at 6.78 MHz. These findings indicate that our approach can efficiently deliver over 50 times more power without increasing magnetic field exposure, making it a promising solution for high-power wireless power transfer applications.

Detecting Insurance Fraud: A Study on Field Fires with Computer Vision and IoT
Creators: name: Thara D K

Publisher: name: Zenodo
Year: 2023

description: The article suggests an automated system for overseeing the fraud detection process related to insurance claims for field fires in agriculture. This innovative solution combines computer vision, deep learning, and the Internet of Things (IoT) to leverage the strengths of each technology. As far as our knowledge extends, such an integration of these technologies has not been previously employed for analyzing insurance fraud in agriculture. The model actively monitors input from IoT devices equipped with infrared and temperature sensors. When these sensor values surpass predefined thresholds, the IoT device captures images of the field. These images are then processed by a fire detection model trained with various classifiers, allowing for performance comparisons. The reported results indicate an impressive accuracy of 97%, with potential for further improvement through a refined dataset specifically tailored for fraud detection.

description: Liquid-phase exfoliation of two-dimensional materials is very attractive for large-scale applications. Although used extensively, isolating MoS2 layers (<10) with high efficiency is reported to be extremely difficult. Further, the importance of soaking has not yet been studied, and the surfactants' role in stabilizing MoS2 nanosheets is poorly understood1. Herein, we report a novel approach to exfoliating large quantities of MoS2 via high-pressure (HP) liquid-phase exfoliation (LPE) in deionized (DI) water. 4 to 7 layers of MoS2 nanosheets were obtained from 60 days-soaked samples and they were found to be stable in solvents for periods of up to six months. Studies on the effect of three surfactants, namely sodium dodecyl benzenesulfonate (SDBS), sodium cholate (SC), and tetra-butyl ammonium bromide (TBAB), indicate that exfoliation of MoS2 nanosheets in SDBS is highly efficient than the other two surfactants. The estimated yield reaches up to 7.25%, with a nanosheet concentration of 1.45 mg/ml, which is one of the highest ever reported. Our studies also suggest that the nanosheets' concentration and the lateral size depend on exfoliation cycles, applied pressure and surfactant concentration. Hydrogen evolution reaction (HER) and ion-transport study show that the nanosheets prepared by our method are stable in an acidic medium and free from surfactants. A high hydrogen evolution rate of 30.13 mmol g-1 h-1 was estimated under ambient laboratory conditions.

radical democratic education

description: We live in interesting times, not least because democracy is both under threat and, in part as a consequence, fitfully and potentially resurgent. In the UK the presumptions of privilege and greed that have for some years disfigured the workings of parliamentary democracy and the, increasingly visible, predatory ambitions and moral indifference of transnational capitalism have prompted Occupy and other similar movements. Not only is there an increasingly widespread willingness to refute and refuse the political passivity and tacit subservience such systems require. There is also a companion resurgence of interest in too readily forgotten traditions of participatory democracy and their more deliberate and wide-ranging insistence on multiple sites and opportunities for democratic engagement. One of the issues this raises for those of us working in the field of education concerns not just the overarching relationship between education and democracy in terms of organisational systems of provision and curricular guidance, but also how a serious commitment to democracy translates into the daily patterns and practices of schools. Perhaps surprisingly, and certainly reprehensibly, it is not, generally, one that is addressed explicitly, honestly or with any degree of sophistication or seriousness. With the current government, as with many of its predecessors, foundational aims limp deferentially and tangentially along behind the overriding ambitions of a narrowly conceived, brashly articulated, economic instrumentalism. Likewise, and predictably, consideration of democracy as a way of young people and adults living and learning together on a daily basis is largely absent.

description: We numerically investigate under which conditions the planet detected at 2.1 AU of Gamma-Cephei could form through the core-accretion scenario despite the perturbing presence of the highly eccentric companion star. We first show that the initial stage of runaway accretion of kilometer-sized planetesimals is possible within 2.5 AU from the central star only if large amounts of gas are present. In this case, gaseous friction induces periastron alignment of the orbits which reduces the otherwise high mutual impact velocities due to the companion's secular perturbations. The following stage of mutual accretion of large embryos is also modeled. According to our simulations, the giant impacts among the embryos always lead to a core of 10 Mearth within 10 Myr, the average lifetime of gaseous discs. However, the core always ends up within 1.5 AU from the central star. Either the core grows more quickly in the inner region of the disc, or it migrates inside by scattering the residual embryos

description: Results. The PCA confirms the existence of the Gnevyshev gap (GG) for solar cycles at about 40% from the start of the cycle. The temporal evolution of sunspot area data for even cycles shows that the GG exists at least at the 95% confidence level for all sizes of sunspots. On the other hand, the GG is shorter and statistically insignificant for the odd cycles of aerial sunspot data. Furthermore, the analysis of sunspot area sizes for even and odd cycles of SC12-SC23 shows that the greatest difference is at 4.2-4.6 years, where even cycles have a far smaller total area than odd cycles. The average area of the individual sunspots of even cycles is also smaller in this interval. The statistical analysis of the temporal evolution shows that northern sunspot groups maximise earlier than southern groups for even cycles, but are concurrent for odd cycles. Furthermore, the temporal distributions of odd cycles are slightly more leptokurtic than distributions of even cycles. The skewnesses are 0.37 and 0.49 and the kurtoses 2.79 and 2.94 for even and odd cycles, respectively. The correlation coefficient between skewness and kurtosis for even cycles is 0.69, and for odd cycles, it is 0.90. Conclusions. The separate PCAs for even and odd sunspot cycles show that odd cycles are more inhomogeneous than even cycles, especially in GSN data. Even cycles, however, have two anomalous cycles: SC4 and SC6. According to the analysis of the sunspot area size data, the GG is more distinct in even than odd cycles. We also present another Waldmeier-type rule, that is, we find a correlation between skewness and kurtosis of the sunspot group cycles.

description: This paper describes a small-scale empirical study grounded in teaching experience which draws upon two principal areas of research: psychological gender and attitudes towards programming and ICT (information and communications technology) in primary schools. The sample group for this study comprised 24 Key Stage 2 pupils who undertook two computing tasks using applications that align with the current UK Primary Computing National Curriculum (DfE 2013a). All children completed a Children’s Sex Role Inventory (CSRI) questionnaire to determine their psychological gender, as well as a computer attitudes (CA) instrument to ascertain their views on computing and ICT. The children’s responses to both instruments were then tested for internal reliability. The pupil participants involved in this research undertook two tasks, which involved the use of programming software, Microsoft Windows LOGO (MWL), and a desktop publishing (DTP) program, Microsoft Publisher. Work samples were then graded to a set of criteria and awarded an overall mark. Although boys marginally outperformed girls overall, the difference between the means did not achieve significance. However, when Pearson product moment correlations were taken between the performances of boys’ means and girls’ means, respectively, across the programming and DTP tasks, they indicated different tendencies. The findings of this small-scale study are limited, but would appear to demonstrate that gender differences do exist in terms of performance across different applications.

description: This action research intervention examined the use of questioning strategies in the classroom, introducing a rich ‘question-diet’ to promote increased learning, engagement and independent thinking. A qualitative approach was taken, using interpretative phenomenological analysis (IPA) to explore the meaning-making and personal experiences of the students' experience of the intervention. The study was conducted with an upper sixth-form psychology class at a west London further education college. The results showed that students reported experiencing increased learning due to underlying factors such as increased independent thinking, effective sharing of knowledge, and increased engagement, all resulting wholly or partly from the questioning strategy adopted. This outcome points to the essential value of using a rich variety of questions, and the benefits of planning when and with which learner to use different question strategies. However, as the intervention was conducted on a relatively small class, there may have been issues with participant reactivity and demand characteristics. Effective methods to reduce bias in classroom action research interventions are outlined and discussed.

description: This paper proposes topology optimization for considering shielding and penetrating features. Based on the fictitious physical model, which is a useful approach to control geometric features, the proposed method analyzes fictitious steady-state temperature fields and interprets target geometric features by examining the temperature change. First, the concept of topology optimization based on the level set method is introduced. Next, the basic idea of the fictitious physical model for considering geometric features is explained. Then, the differences between the shielding and penetrating features are clarified, and the fictitious physical model for evaluating these features is proposed. Furthermore, topology optimization for the minimum mean compliance problem with geometric conditions is formulated. Finally, 2D and 3D numerical examples are presented to validate the proposed method.

description: This is an update of CERI-SR07-01, our report on international crop policies conducted in February of 2007. Since then, the landscape for agricultural products has undergone changes due to developments related to the use of ethanol and the recent economic recession. Also, in most of the world, both developed economies such as the EU, Australia, and the U.S., and developing countries such as China and Brazil, have increased their domestic agricultural supports and/or altered the types of support. It is uncertain if this increase is permanent or transitory.

description: The interaction between large internal motion of DNA surrounded by bio-fluid is investigated. The phenomenon is modelled using the relativistic Navier-Stokes lagrangian describing the bio-fluid coupled to the standard Klein-Gordon lagrangian describing the DNA. It is shown that the equation of motion at non-relativistic limit, v << c, reproduces the well-known Sine-Gordon equation. The effect of the interaction in a single soliton solution is also given and discussed.

Speeding up a single-molecule DNA motor with a simple catalyst

description: We demonstrate a catalytic control method for speeding up the single-molecule DNA motor introduced by Li and Tan [Nano Lett. {\bf 2}, 315 (2002)]. A key rate-limiting barrier in the reaction part of the cycle is the tendency for the second fuel strand $B$ to fold into the chair-like configuration of the original motor strand $M$. This seriously impedes the restoration reaction. We have designed a catalytic strand to inhibit the folding of $B$. Introduction of the catalyst speeds up the restoration reaction by roughly a factor of 2. The catalyst shows robust behavior for more than one cycle. The experimental data can be understood with a model with intermediate products. This technique provides dynamic control of the restoration rate of the motor without affecting the straightening rate.

Brans-Dicke Scalar Field as a Unique k-essence

description: In the present work, the Brans-Dicke theory of gravity is taken as a possible theory of k-essence coupled to gravity and then the role played by the Brans-Dicke scalar field in relation to the unified model for dark matter and dark energy is explored. It has been realized that the BD scalar field does indeed play a role of a k-essence, but in a very unique way which distinguishes it from other k-essence fields studied in the literature such as the (generalized) Chaplygin gas or the purely kinetic k-essence studied recently by Scherrer. That is, instead of providing an interpolation between the dark matter-like evolution and the dark energy-like evolution, the BD theory predicts the emergence of a yet-unknown {\it zero acceleration} epoch which is an intermediate stage acting as a ``crossing bridge'' between the decelerating matter-dominated era and the accelerating phase.

On the application of Effective Field Theory to finite-volume effects in $a_μ^{\rm HVP}$

description: One of the more important systematic effects affecting lattice computations of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon, $a_μ^{\rm HVP}$, is the distortion due to a finite spatial volume. In order to reach sub-percent precision, these effects need to be reliably estimated and corrected for, and one of the methods that has been employed for doing this is finite-volume chiral perturbation theory. In this paper, we argue that finite-volume corrections to $a_μ^{\rm HVP}$ can, in principle, be calculated at any given order in chiral perturbation theory. More precisely, once all low-energy constants needed to define the Effective Field Theory representation of $a_μ^{\rm HVP}$ in infinite volume are known to a given order, also the finite-volume corrections can be predicted to that order in the chiral expansion.

description: Cotton quality is a fundamental element in price determination because quality heterogeneity is so prevalent in cotton and combinations of quality attributes have a known effect on its value in manufacturing textile products (Ethridge, Hudson, and Misra, 2005). The fiber is most often spun into thread and used to make a soft, breathable textile, which is the most widely used natural-fiber cloth in clothing today (Merriam and Webster, 2006). Cotton fiber is made up of different attributes whose values together determine its use value and market value. Official grading standards recognize eight attributes - fiber length, fiber length uniformity, fiber strength, micronaire, color, trash, preparation, and extraneous material (USDA, 1993).
Adaptive Mesh Refinement Simulations of the Ionization Structure and Kinematics of Damped Ly$α$ Systems with Self-consistent Radiative Transfer

description: We use high resolution Eulerian hydrodynamics simulations to study kinematic properties of the low ionization species in damped Ly-alpha systems at redshift z=3. Our adaptive mesh refinement simulations include most key ingredients relevant for modeling neutral gas in high-column density absorbers: hydrodynamics, gravitational collapse, continuum radiative transfer and gas chemistry, but no star formation. We model high-resolution Keck spectra with unsaturated low ion transitions in two Si II lines (1526 and 1808 A), and compare simulated line profiles to the data from the SDSS DLA survey. We find that with increasing grid resolution the models show a trend in convergence towards the observed distribution of HI column densities. While in our highest resolution model we recover the cumulative number of DLAs per unit absorption distance, none of our models predicts DLA velocity widths as high as indicated by the data, suggesting that feedback from star formation might be important. At z=3 a non-negligible fraction of DLAs with column densities below 10^21 cm^-2 is caused by tidal tails due to galaxy-galaxy interactions in more massive halo environments. Lower column density absorbers with N_HI < 10^21.4 cm^-2 are sensitive to changes in the UV background resulting in a 10% reduction of the cumulative number of DLAs for twice the quasar background relative to the fiducial value. We find that the mass cut-off below which a large fraction of dwarf galaxies cannot retain gas after reionization is 7*10^7 msun, lower than the previous estimates. Finally, we show that models with self-shielding commonly used in the literature produce significantly lower DLA velocity widths than the full radiative transfer runs.

description: In recent years there has been a growing interest in the statistical properties of surfaces growing under deposition of material. Yet it is clear that a theory describing the evolution of a surface should at the same time describe the properties of the bulk buried underneath. Clearly, the structure of the bulk is relevant for many practical purposes, such as the transport of electric current in devices, transport of fluids in geological formations and stress transmission in granular systems. The present paper demonstrates explicitly how models describing deposition can provide us with information on the structure of the bulk. Comparison of an analytic model with a simulation of a discrete growth model reveals an interesting long range tail in the density-density correlation in the direction of deposition.
