description: This paper is written from a sociology of science/rhetoric of science perspective. The paper critiques the central rhetorical constructions of neoclassical economic studies as applied to agricultural cooperative conversions. Conversions refer to the internal re-structurings, sell-outs, and hybridizations of cooperative organizational form to investment oriented structures. Neoclassical economics analyses of conversions are based within an "individualist-idealist" metaphor. This metaphor, as articulated in neo-classical economics, does not allow the scientist to see historical and sociological aspects of cooperatives, and broader, more holistic implications of conversions. We argue for broadening the conversation to include social materialist, and social voluntarist metaphors, for more complete expression of the practical implications of the conversion of agricultural cooperatives, and to suggest the importance of self-awareness in doing science.

description: When relating the strong coupling $α_s$, measured at the scale of the $Z$ boson mass, to its numerical value at some higher energy, for example the scale of Grand Unification, it is important to include higher order corrections both in the running of $α_s$ and the decoupling of the heavy particles. We compute the two-loop matching coefficients for $α_s$ within the Minimal Supersymmetric Standard Model (MSSM) which are necessary for a consistent three-loop evolution of the strong coupling constant. Different scenarios for the hierarchy of the supersymmetric scales are considered and the numerical effects are discussed. We find that the three-loop effects can be as large as and sometimes even larger than the uncertainty induced by the current experimental accuracy of $α_s(M_Z)$.

description: Let $Q$ be an acyclic quiver and $k$ be an algebraically closed field. The indecomposable exceptional modules of the path algebra $kQ$ have been widely studied. The real Schur roots of the root system associated to $Q$ are the dimension vectors of the indecomposable exceptional modules. It has been shown in [Nájera Chávez A., Int. Math. Res. Not. 2015 (2015), 1590-1600] that for acyclic quivers, the set of positive $c$-vectors and the set of real Schur roots coincide. To give a diagrammatic description of $c$-vectors, K-H. Lee and K. Lee conjectured that for acyclic quivers, the set of $c$-vectors and the set of roots corresponding to non-self-crossing admissible curves are equivalent as sets [Exp. Math., to appear, arXiv:1703.09113]. In [Adv. Math. 340 (2018), 855-882], A. Felikson and P. Tumarkin proved this conjecture for 2-complete quivers. In this paper, we prove a revised version of Lee-Lee conjecture for acyclic quivers of type $A$, $D$, and $E_{6}$ and $E_7$.

Inverse transfer of magnetic helicity in direct numerical simulations of compressible isothermal turbulence: helical transfers

description: The role of the different helical components of the magnetic and velocity fields in the inverse spectral transfer of magnetic helicity is investigated through Fourier shell-to-shell transfer analysis. Magnetic helicity transfer analysis is performed on chosen data from direct numerical simulations of homogeneous isothermal compressible magnetohydrodynamic turbulence, subject to both a large-scale mechanical forcing and a small-scale helical electromotive driving. The root mean square Mach number of the hydrodynamic turbulent steady state taken as initial condition varies from 0.1 to about 11. Three physical phenomena can be distinguished in the general picture of the spectral transfer of magnetic helicity towards larger spatial scales: local inverse transfer (LIT), non-local inverse transfer (NLIT) and local direct transfer (LDT). A shell decomposition allows these three phenomena to be associated with clearly distinct velocity scales: the LDT is driven by large-scale velocity shear and associated with a direct magnetic energy cascade; the NLIT is mediated by small-scale velocity fluctuations which couple small- and large-scale magnetic structures; and the LIT by the intermediate spatial scales of the velocity field. The helical decomposition shows that like-signed helical interactions and interactions with the compressive velocity field are predominant. The latter has a high impact on the LDT and on the NLIT, but plays no role for the LIT. The locality and relative strength of the different helical contributions are mainly determined by the triad helical geometric factor, derived here in the compressible case.
China's Rural Shareholding Cooperatives as a Form of Multi-Stakeholder Cooperation

description: Township and village enterprises (TVEs) are the fastest growing sector of China's economy. Their development has been shaped by their close ties with local governments and communities. However, as marketization processes dissolve these links, the increasing competitive pressures of the 1990s make the search for new forms of enterprise organization a priority. The Shareholding Cooperative System (SCS) has been proposed as a method of strengthening enterprise autonomy whilst preserving the predominance of public ownership, and of improving enterprise efficiency by tying performance to profitability whilst maintaining some principles of equity. In practice, the new opportunities opened up by reform are often monopolized by those already in positions of wealth and power: local governments and individual entrepreneurs. But workers and local farmers may also become more directly involved in enterprise ownership, gaining a greater say in decision-making. In these cases, the SCS resembles a multi-stakeholder cooperative in which workers, managers, local governments and local farmers negotiate around their stakes in the future of the enterprise.

description: Recently in 2018, Niu et al. proposed a measurement-device-independent quantum secure direct communication protocol using Einstein-Podolsky-Rosen pairs and generalized it to a quantum dialogue protocol (Niu et al., Science bulletin 63.20, 2018). By analyzing these protocols we find some security issues in both these protocols. In this work, we show that both the protocols are not secure against information leakage, and a third party can get half of the secret information without any active attack. We also propose suitable modifications of these protocols to improve the security.
Competitive or Consensual Economics?

description: A dramatic change has taken place in the dominant paradigm of economic discussion. Cold War rhetoric has been replaced by a renewed debate between two old antagonists: competition between conflicting private interests and a consensual approach that emphasizes shared interests. Competitive capitalism stresses individual initiative and private rights, concentrates on the growth of wealth, and tends to ignore social conditions. Consensual economics uses a communal or holistic approach, gives priority to the public interest, and regards the quality of life as more important than wealth. Guilds and kibbutzim are prominent examples of that consensual approach, and there is much to be learned from their experience.
Noise storm continua: power estimates for electron acceleration

Subjects: subject: Astrophysics (astro-ph)

description: We use a generic stochastic acceleration formalism to examine the power $L_{\rm in}$ (${\rm erg s^{-1}}$) input to nonthermal electrons that cause noise storm continuum emission. The analytical approach includes the derivation of the Green's function for a general second-order Fermi process, and its application to obtain the particular solution for the nonthermal electron distribution resulting from the acceleration of a Maxwellian source in the corona. We compare $L_{\rm in}$ with the power $L_{\rm out}$ observed in noise storm radiation. Using typical values for the various parameters, we find that $L_{\rm in} \sim 10^{23-26}$ ${\rm erg s^{-1}}$, yielding an efficiency estimate $η\equiv L_{\rm out}/L_{\rm in}$ in the range $10^{-10} \lsim η\lsim 10^{-6}$ for this nonthermal acceleration/radiation process. These results reflect the efficiency of the overall process, starting from electron acceleration and culminating in the observed noise storm emission.

Reliability study of North American dimension lumber in the Chinese timber structures design code
Creators: name: Zhuang, Xiaojun
Publisher: name: University of British Columbia
Year: 2009

description: Reliability evaluation principles, procedures as applied in the Chinese timber structure design code were reviewed. The general method to establish the design values of Chinese wood strength properties was investigated. In particular, Chinese load information, including the statistical models and parameters, was analyzed. Also, the reliability associated with wood structural design requirements in Canada was studied. The emphasis was placed on the in-grade testing method, which is a more reliable method to get the lumber strength properties compared with small clear wood testing method used in China. Finally, Canadian procedures for establishing the design values of wood strength properties were reviewed. Using Chinese load information and Canadian in-grade testing data, reliability evaluations were conducted for the design values of common Canadian Species in the Chinese timber design code. These design values were previous soft converted from allowable stresses approved by the American Lumber Standards Committee. Reliability results were compared with the target reliability levels tabulated in the Chinese national unified reliability code. This reliability analysis was implemented by using the "RELAN" (Reliability ANalysis) program developed by Dr. R.O. Foschi of UBC. Recommendations were made to develop a formal reliability evaluation of the performance of North American dimension lumber under the Chinese load conditions.

description: A novel Huygens' transmit-array is proposed based on a coupled-resonator approach where two identical elliptical metallic patches with an elliptical hole separated by a dielectric substrate has been used to demonstrate millimeter-wave (mm-Wave) beam-forming for linear polarization. The proposed structure is simple and compatible with standard Printed Circuit Board (PCB) processes and utilizes a single dielectric substrate only. It is shown that by engineering the geometrical dimensions of the resonator, its electric (even-mode) and magnetic (odd-mode) resonances are excited in a balanced manner to achieve zero back-scattering in a large bandwidth. This operation principle of the proposed Huygens' cell is explained in details using both an insightful equivalent circuit model, as well as full-wave eigenmode analysis. Next, the proposed Huygens' cell is placed on top of a high gain 2D slot-array antenna, in its near-field, to engineer its aperture field distribution, where the resulting Huygens' transmit-array acts as a broadband phase plate. Several transmit-array prototypes designed around the 60 GHz frequency band are demonstrated and experimentally characterized in both their near and far-fields, to achieve difference pattern generation, beam expansion and beam steering as application examples, in addition to a uniform surface demonstrating its low-loss performance. Further discussions related to the unit cell size vs frequency bandwidth trade-offs and future extension to handling circular polarization are finally provided.

description: One of the characteristics of the kibbutz was that it belonged to a nation-wide movement, it was open to the outside world and was involved in all aspects of society. In view of the changes taking place in the kibbutzim and in their surroundings the kibbutz may forfeit its characteristics as an assertive and centralized, or at least federative, organization. In consequence the kibbutz may cease to be a social movement seeking to attain goals of universal value and turn into an organized self-interested pressure group. The dilemma faced by the kibbutz is whether it will be a system of egotistic people seeing themselves as shrewd-calculating-yuppies, or members of a social movement seeking to attain goals of universal value, considered by others as "freiers"

Food Security and Poverty

description: The core idea presented in this paper is a model of the economic system that seeks a larger role for the domestic economy vis-a-vis the money economy. It is argued that labor applied in the domestic economy can add value in ways that can have a significant impact on the standards and quality of life for the poor. Cooperative self-help principles applied to families and friendship groups are the mechanism for mobilizing the domestic economy's forces of production with the mainstream cooperatives directing their existing member relations and member education facilities to act as promoters and facilitators of the idea. The strategy is presented as an alternative to the employment creation-oriented anti-poverty policies favored in the West. The author claims that the re-establishing of well-being and autonomy within the domestic economy will reduce pressure for jobs in the labor market particularly for marginal employment. This reduction in pressure for jobs will feed through to improve the relative balance of market power towards labor and at the same time take pressure off the national exchequers struggling with subsidizing the low wage-benefit supported labor market of the 1990s. The whole paper is presented as a speculation that is worth further consideration and research in the absence of viable alternatives to the present failed anti-poverty programs.

description: This study introduces SECODA, a novel general-purpose unsupervised non-parametric anomaly detection algorithm for datasets containing continuous and categorical attributes. The method is guaranteed to identify cases with unique or sparse combinations of attribute values. Continuous attributes are discretized repeatedly in order to correctly determine the frequency of such value combinations. The concept of constellations, exponentially increasing weights and discretization cut points, as well as a pruning heuristic are used to detect anomalies with an optimal number of iterations. Moreover, the algorithm has a low memory imprint and its runtime performance scales linearly with the size of the dataset. An evaluation with simulated and real-life datasets shows that this algorithm is able to identify many different types of anomalies, including complex multidimensional instances. An evaluation in terms of a data quality use case with a real dataset demonstrates that SECODA can bring relevant and practical value to real-world settings.

description: Néhány évtizeddel ezelőtt a vidék és a mezőgazdaság fő feladata az volt, hogy elegendő mennyiségű és megfelelő minőségű élelmiszert és ipari alapanyagot állítson elő, hatékonyan foglalkoztatva a vidéki népesség jelentős hányadát. Később felmerült, hogy csökkenteni kellene az agrárium okozta környezeti terhelést, elsősorban a vegyszerfelhasználást minimalizálva. Ebből a törekvésből fejlődött ki a ma már az egész fejlett világban sikeres biotermesztés, ökológiai gazdálkodás. A század- és ezredfordulón azonban új, sokkal diverzifikáltabb igények is megjelentek; a klímaváltozást előidéző gázok kibocsátás-csökkentésétől a helyi termékek fogyasztásáig, az élelmiszer-biztonságtól a szegény országok megsegítéséig. Tanulmányunk ezekre az új kihívásokra (food miles, locavore, virtuális víz, etikus gazdálkodás) adandó lehetséges agrárgazdasági válaszokkal foglalkozik. Az értékeléshez a teljes életciklus (LCA) és a költség–haszon (CBA) elemzés módszereit, a tevékenységekhez a proaktivitást ajánljuk. ------------------------------------------ A few decades ago the main task of agriculture was the production of food and industrial row material in sufficient quantity and quality thereby employing a significant proportion of country population. Later it transpired that agricultural pollution of the environment should be reduced by mainly minimising the use of agricultural chemicals. These aspirations lead to the development of bio-cultivation or ecological farming, which is now a success throughout the developed world. At the turn of century and millennia further pursuits appeared; the reduction of gas emissions responsible for global warming to consumption of local products and food safety to aiding poor countries. Our study was concerned with possible agricultural approaches to these new challenges (food miles, locavore, virtual water, ethical farming). We recommend the method of total life cycle assessment (LCA) and cost-benefit (CBA) analyses for evaluation and pro-activity for operations.

It makes use of the built-in ability of the wavelets for capturing the trends in a data set, in variable window sizes. Discrete wavelets from the Daubechies family are used to illustrate the efficacy of this procedure. After studying binomial multifractal time series with the present and earlier approaches of detrending for comparison, we analyze the time series of averaged spin density in the 2D Ising model at the critical temperature, along with several experimental data sets possessing multi-fractal behavior.

description: Cross-site scripting (XSS) flaws are a class of security flaws that permit the injection of malicious code into a web application. In simple situations, these flaws can be caused by missing input sanitizations. Sometimes, however, all application inputs are sanitized, but the sanitizations are not appropriate for the browser contexts of the sanitized values. Using an incorrect sanitizer can make the application look protected, when it is in fact vulnerable as if no sanitization was used, creating a context-sensitive XSS flaw. To discover context-sensitive XSS flaws, we introduce DjangoChecker. DjangoChecker combines extended dynamic taint tracking with a model browser for context analysis. We demonstrate the practical application of DjangoChecker on eight mature web applications based on Django, discovering previously unknown flaws in seven of the eight applications, including highly severe flaws that allow arbitrary JavaScript execution in the seven flawed applications.
Degasperis-Procesi peakons and the discrete cubic string

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)

description: We use an inverse scattering approach to study multi-peakon solutions of the Degasperis-Procesi (DP) equation, an integrable PDE similar to the Camassa-Holm shallow water equation. The spectral problem associated to the DP equation is equivalent under a change of variables to what we call the cubic string problem, which is a third order non-selfadjoint generalization of the well-known equation describing the vibrational modes of an inhomogeneous string attached at its ends. We give two proofs that the eigenvalues of the cubic string are positive and simple; one using scattering properties of DP peakons, and another using the Gantmacher-Krein theory of oscillatory kernels. For the discrete cubic string (analogous to a string consisting of n point masses) we solve explicitly the inverse spectral problem of reconstructing the mass distribution from suitable spectral data, and this leads to explicit formulas for the general n-peakon solution of the DP equation. Central to our study of the inverse problem is a peculiar type of simultaneous rational approximation of the two Weyl functions of the cubic string, similar to classical Pade-Hermite approximation but with lower order of approximation and an additional symmetry condition instead. The results obtained are intriguing and nontrivial generalizations of classical facts from the theory of Stieltjes continued fractions and orthogonal polynomials.

description: Az elmúlt években több elemzés látott napvilágot azzal kapcsolatban, hogy Magyarország adottságai melyik megújítható energiaforrás hangsúlyozott felhasználására alkalmasak. A korábban jellemző mezőgazdasági túltermelés, klímaváltozás, a fosszilis energiahordozók drasztikus és tartós áremelkedése azonban hazánkban is a bioüzemanyagok irányába terelte a figyelmet. A fokozott érdeklődést indokolja továbbá, hogy a biomassza ilyen irányú felhasználása komplex megoldást kínál nem csupán a fenti problémákra, de a gazdálkodók számára is lehetőséget nyújt az optimális és az életszínvonal emelésére is alkalmas termelési szerkezet kialakítására. A kutatás során a szakirodalomban fellelhető módszertan kiegészítésével és részbeni átalakításával olyan elemzés készült, amely Magyarország régióit a bioüzemanyagok alkalmazhatósága tekintetében komplexen értékeli. A vizsgálat lehetővé tette, hogy az egyes régiókat a fellelhető statisztikai adatok felhasználásával rangsorolja. Jelen esetben nem volt cél gazdaságossági, üzemtani számítások elvégzése, de kétségtelen, hogy optimális (de legalábbis ahhoz közelítő) piaci szerkezet ezekkel együtt alakítható ki. Jelen tanulmány olyan lehetséges számítási mód bemutatására vállalkozott, amely a rendszerszemlélet követelményeire tekintettel értékelte Magyarország régióit. --------------------------- In the past years several analyses appeared dealing with the issue of renewable energy resources in Hungary, namely which of them would suit best conditions in this country. Agricultural over¬production characteristic of previous decades, climate change and the continued and drastic rise of fossil fuels prices directed attention to bi-fuels also in this country. Furthermore such a use of bio-mass offers a complex solution to not only the above problems, but also it offers farmers the possibility to develop an optimal production structure leading to enhanced living standard. On the basis of methods described in the literature (complemented and/or modified) a complex analysis was prepared evaluating the regions of Hungary from the point of view of bio-fuels applicability. Each region was individual assessed on the basis published statistical data. The economic and technological assessment of bio-fuels production was not an objective of our study, although undoubtedly these are needed for establishing optimal market structures. This study presents a possible method of analysis assessing the regions of Hungary from a point of view based on the conditions of systems approach.

description: The Blandford-Znajek constraint equation for a stationary, axisymmetric black-hole force-free magnetosphere is cast in a 3+1 absolute space and time formulation, following Komissarov (2004). We derive an analytic solution for fields and currents to the constraint equation in the far-field limit that satisfies the Znajek condition at the event horizon. This solution generalizes the Blandford-Znajek monopole solution for a slowly rotating black hole to black holes with arbitrary angular momentum. Energy and angular momentum extraction through this solution occurs mostly along the equatorial plane. We also present a nonphysical, reverse jet-like solution.

Density, body condition, and movement of coastal cutthroat trout (Oncorhynchus clarki clarki) in logged and forested headwater streams of southwestern British Columbia
Creators: name: De Groot, Jennifer D.
Publisher: name: University of British Columbia
Year: 2009

description: Coastal cutthroat trout (O. clarki clarki) rear in small, headwater streams that may be particularly susceptible to impacts from land-use activities such as logging. Headwater populations of coastal cutthroat trout were trapped from 1997 to 2002 to investigate: (i) the effects of second-growth logging on trout densities and summer body condition over summer and winter months; (ii) the influence of physical habitat characteristics on summer trout densities; and (iii) the characteristics of winter trout movement within different habitat conditions. Trout mean summer densities in logged streams showed no decline following harvest, nor were there any large changes evident to physical habitat. However, among years, mean summer trout densities were higher in streams with deeper pools. Though summer trout densities remained unchanged in logged streams, trout densities in control streams declined. This suggests that trout may actually have benefited from logging, potentially due to enhanced levels of primary productivity arising from the removal of riparian canopy. Winter trout densities were similar to summer values, indicating that these headwater streams provided suitable conditions for trout populations year-round. Low flows during late summer, which reduce pool depth, may be more limiting to age 1 and older cutthroat trout found in coastal headwater streams than winter high-flow events. Increases in stream temperatures following logging activities were not associated with enhanced summer body conditions of trout, largely because minor temperature effects of logging (average increases of 1-2° C) were offset by a colder-than-average post-logging period. Winter movement (average 2-7 habitat units or 21-40 m) was found to be a common behaviour of coastal cutthroat trout in headwater streams and did not seem to be mediated by dominance hierarchies, influenced by riparian forest condition, or confer a growth advantage/ disadvantage for trout. Winter movement, however, was somewhat limited and may be a reflection of the need for trout to seek deeper pool habitats that provide cover and refuge from high-discharge events. Land-use management practices that protect existing pools and facilitate the processes that create pools may ensure the continued persistence of coastal cutthroat trout populations in headwater streams of southwestern British Columbia.

description: New formulation of relativistic wave equations (RWE) for massive particles with arbitrary half-integer spins s interacting with external electromagnetic fields are proposed. They are based on wave functions which are irreducible tensors of rank $n ($n=s-\frac12$) antisymmetric w.r.t. n pairs of indices, whose components are bispinors. The form of RWE is straightforward and free of inconsistencies associated with the other approaches to equations describing interacting higher spin particles.

description: The outer shells of young supernova remnants (SNRs) are the most plausible acceleration sites of high-energy electrons with the diffusive shock acceleration (DSA) mechanism. We studied spatial and spectral properties close to the shock fronts in four historical SNRs (Cas A, Kepler's remnant, Tycho's remnant, and RCW 86) with excellent spatial resolution of {\it Chandra}. In all of the SNRs, hard X-ray emissions were found on the rims of the SNRs, which concentrate in very narrow regions (so-called "filaments"); apparent scale widths on the upstream side are below or in the order of the point spread function of {\it Chandra}, while 0.5--40 arcsec (0.01--0.4 pc) on the downstream side with most reliable distances. The spectra of these filaments can be fitted with both thermal and nonthermal (power-law and {\tt SRCUT}) models. The former requires unrealistic high temperature ($\ga$2 keV) and low abundances ($\la$1 solar) for emission from young SNRs and may be thus unlikely. The latter reproduces the spectra with best-fit photon indices of 2.1--3.8, or roll-off frequencies of (0.1--28)$\times 10^{17}$ Hz, which reminds us of the synchrotron emission from electrons accelerated via DSA. We consider various physical parameters as functions of the SNR age, including the previous results on SN 1006 \citep{bamba2003b}; the filament width on the downstream side increases with the SNR age, and the spectrum becomes softer keeping a nonthermal feature. It was also found that a function, that is the roll-off frequency divided by the square of the scale width on the downstream side, shows negative correlation with the age, which might provide us some information on the DSA theory.

description: M. Friedman szerint a válságokat a pénzellátás egyenletességének megsértése generálja, mert a monetárszférában előidézett fluktuáció a reálszférára átterjedve ott (válság)ciklusokat eredményez. Friedman kimutatja a Philips-görbe hamis voltát, „természetes ráta” hipotézisében cáfolva azt. A munkanélküliség és az infláció között nincs kapcsolat. A pénzellátás egyenletessége mellett a pénzstabilitás kap még primátust a monetaristáknál, minden más célt megelőzve, az inflációnak a gazdasági makroszerkezetre való káros hatása miatt. ------------------- According to M Friedman crises are generated by the violation of even money supply as any fluctuations induced in the monetary sphere spreads to the real world causing (crisis) cycles. Friedman has proven the falsehood of the Phillips-curve, which he refuted in his “natural rate” hypothesis. There is no connection between unemployment and inflation. Apart from the evenness of money supply, monetarist place money stability to above all, because of the harmful effects of inflation on the economic macrostructure.

description: Using the method of QCD light-cone sum rules, we calculate the $B \to ππ$ hadronic matrix elements with annihilation topology. We obtain a finite result, including the related strong phase. Numerically, the annihilation effects in $B\to ππ$ turn out to be small with respect to the factorizable emission mechanism. Our predictions, together with the earlier sum rule estimates of emission and penguin contributions, are used for the phenomenological analysis of $B\to ππ$ channels. We predict a $ΔI=1/2$ transition amplitude which significantly differs from this amplitude extracted from the current data.

description: A tanulmány a globális pénzügyi és gazdasági válság klímaváltozás – fenntart¬hatóság – globalizáció rendszerébe illesztve olyan változásokat javasol – előnyt kovácsolva a kényszerből –, melyek számolnak a tényleges helyzettel és viszonylag kisebb áldozatokkal, valamint kockázattal megvalósíthatók. Ennek lényege tömören a termőföld-hasznosítás tudatos arányváltásai, a foglalkoztatás bővítése, integrációk szervezése és az oktatás korszerűsítése. Ajavasoltak nem veszélyeztetik hazánk élelmiszer-ellátásának biztonságát, de csökkentik az agrárágazatok, a vidék energiaköltségeit, energiafüggőségét, új munkahelyeket teremtenek, javítják a mezőgazdaságból és a vidéken élők anyagi körülményeit, hozzájárulnak az ország energiafüggőségének csökkenéséhez, így a gazdasági válságból való kilábaláshoz. ---------------------------------------- Making a virtue of necessity, the paper proposes changes which are based on an in-depth knowledge of the current situation with respect to the global financial and economic crisis, climate change, sustainability and globalisation, and involve relatively small sacrifices and risks. In a nutshell, these changes focus on modifying land use patterns, increasing employment rates, promoting integration and modernising education. The suggested changes do not compromise the safety of the country’s food supply. They lower the energy consumption and energy dependency of agriculture and rural areas, lead to new jobs, improve the financial well-being of rural communities, and alleviate the country’s energy dependency. Through all this, they help escape the current crisis.
Epistemically restricted phase space representation, weak momentum value, and reconstruction of quantum wave function

description: A phase space distribution associated with a quantum state was previously proposed, which incorporates a specific epistemic restriction parameterized by a global random variable on the order of Planck constant, transparently manifesting quantum uncertainty in phase space. Here we show that the epistemically restricted phase space (ERPS) distribution can be determined via weak measurement of momentum followed by post-selection on position. In the ERPS representation, the phase and amplitude of the wave function are neatly captured respectively by the position-dependent (conditional) average and variance of the epistemically restricted momentum fluctuation. They are in turn respectively determined by the real and imaginary parts of the weak momentum value, permitting a reconstruction of wave function using weak momentum value measurement, and an interpretation of momentum weak value in term of epistemically restricted momentum fluctuations. The ERPS representation thus provides a transparent and rich framework to study the deep conceptual links between quantum uncertainty embodied in epistemic restriction, quantum wave function, and weak momentum measurement with position post-selection, which may offer useful insight to better understand their meaning.

description: We developed a new type of AC microcalorimeter based on a modulated-bath technique for measuring the specific heat of small microgram samples in the temperature range from 30-300 K, and tested it in magnetic fields up to 14 T. The device is built from a modified commercial Peltier element. The temperature of its top plate can be modulated periodically by Peltier effect, so that the oscillation is symmetrical about the temperature of the main bath. This avoids the problem of DC offsets which plagues conventional AC calorimeters. The sample is attached to a thin thermocouple cross, acting as a weak thermal link to a platform. The absence of a heater reduces the background heat capacity ('addenda') to a minimum. As an illustrative example of the performance of our device, the specific heat in fields up to 14 T of a small single crystal of the high-temperature superconductor Bi2.12Sr1.71Ca1.22Cu1.95Oy has been determined.

description: A 2013 utáni időszakra szóló KAP-reform keretében egyes tagállamok máris felvetették a közvetlen termelői támogatások jelentős csökkentését. Acikk 2006. évi támogatási és jövedelmi adatok alapján azt vizsgálja, hogy egy drasztikus, 50 százalékos támogatáscsökkenésnek milyen hatásai valószínűsíthetők, ha a termelés egyéb feltételei nem változnának. Az elemzés szerint egy ilyen lépésnek Magyarországon sokrétű és rendkívül hátrányos következményei lennének, nemcsak a mezőgazdaságra, hanem az egész nemzetgazdaságra, különösképpen pedig a vidéki foglalkoztatási viszonyokra és a természeti környezetre nézve. Minden szempontból hátrányosan érintené általában a vidéket, különösen a lemaradó és stagnáló kistérségeket, továbbá a kedvezőtlen adottságú területeket, általánosan az országnak azon részeit, ahol most is jelentősek a társadalmi-gazdasági feszültségek. Magyarországnak alap¬vető érdeke, hogy ne legyenek hirtelen, drasztikus módosítások, a rendszer változtatásában csak fokozatos megoldások kívánatosak. Európa számára alapvető érték a természeti környezet óvása, az élelmiszer- és az élelmezés-biztonság. Ez utóbbi pedig nemcsak európai szinten, hanem regionálisan is fontos érték, védelmet érdemel, ami meggondolatlan pénzügyi lépések oltárán nem áldozható fel! ----------------------------------------- Some Member States have already raised the idea of a significant cut to direct aid to farms as part of the CAP reform as of 2013. Based on revenue data for 2006, the paper explores the likely effects of a drastic cut of 50% in aids, provided that the other conditions of production are unchanged. The analysis showed that this act would have manifold, very damaging consequences not only to agriculture but also to the entire national economy, especially rural employment rates and the natural environment. It would de detrimental to rural areas from every aspect, especially disadvantaged and stagnating micro-regions, as well as areas lacking economic resources – all in all, parts of the country where social and economic tension is already strong. Hungary is fundamentally interested in avoiding abrupt drastic changes. Only gradual modification is desirable. Protecting our natural environment and ensuring the safety of food supply are among the elementary interests of Europe. The latter is not only important for Europe in general, but also on a regional level, and should be protected, rather than sacrificed on the altar of ill-considered financial measures!

description: The pion re-scattering operator for pion production, derived recently in time-ordered perturbation theory, is compared with the one following from the simple S-matrix construction. We show that this construction is equivalent to the on-shell approximation introduced in previous papers. For a realistic NN interaction, the S-matrix approach, and its simplified fixed threshold-kinematics version, work well near threshold.
