description: We investigate here a supermatrix model with a mass term and a cubic interaction. It is based on the super Lie algebra osp(1|32,R), which could play a role in the construction of the eleven-dimensional M-theory. This model contains a massive version of the IIB matrix model, where some fields have a tachyonic mass term. Therefore, the trivial vacuum of this theory is unstable. However, this model possesses several classical solutions where these fields build noncommutative curved spaces and these solutions are shown to be energetically more favorable than the trivial vacuum. In particular, we describe in details two cases, the SO(3) \times SO(3) \times SO(3) (three fuzzy 2-spheres) and the SO(9) (fuzzy 8-sphere) classical backgrounds.

Single Pulse Detection Algorithms for Real-time Fast Radio Burst Searches using GPUs

description: The detection of non-repeating or irregular events in time-domain radio astronomy has gained importance over the last decade due to the discovery of fast radio bursts. Existing or upcoming radio telescopes are gathering more and more data and consequently the software, which is an important part of these telescopes, must process large data volumes at high data rates. Data has to be searched through to detect new and interesting events, often in real-time. These requirements necessitate new and fast algorithms which must process data quickly and accurately. In this work we present new algorithms for single pulse detection using boxcar filters. We have quantified the signal loss introduced by single pulse detection algorithms which use boxcar filters and based on these results, we have designed two distinct "lossy" algorithms. Our lossy algorithms use an incomplete set of boxcar filters to accelerate detection at the expense of a small reduction in detected signal power. We present formulae for signal loss, descriptions of our algorithms and their parallel implementation on NVIDIA GPUs using CUDA. We also present tests of correctness, tests on artificial data and the performance achieved. Our implementation can process SKA-MID-like data 266$\times$ faster than real-time on a NVIDIA P100 GPU and 500x faster than real-time on a NVIDIA Titan V GPU with a mean signal power loss of 7%. We conclude with prospects for single pulse detection for beyond SKA era, nanosecond time resolution radio astronomy.

description: One of the goals of geographical indications in the EU is to contribute to rural development of remote and less-favoured areas. On the base of a rough estimation of the uptake of geographical indications in mountain and island areas of the EU, it can be concluded that indeed agricultural and food producers of such areas demonstrate a significantly higher use of geographical indication than average in the EU. However, the differences of geographical features reflect themselves in the fact that this use is not uniform: mountain stakeholders do rely more on geographical indications than islands ones. This is an indication that regional and/or rural policies need to be tailored to the local geographical, economic and social specificities of each area concerned.

description: We complete the description of semistable models for modular curves associated with maximal subgroups of $\mathrm{GL}_2 (\F_p )$ (for $p$ any prime, $p>5$). That is, in the new cases of non-split Cartan modular curves and exceptional subgroups, we identify the irreducible components and singularities of the reduction mod~$p$, and the complete local rings at the singularities. We review the case of split Cartan modular curves. This description suffices for computing the group of connected components of the fibre at~$p$ of the N\'eron model of the Jacobian.

Tidal truncation of gas replenishment and global suppression of galactic star formation in distant clusters

description: Recent spectroscopic observations of galaxies in distant clusters have revealed that the rate of star formation in star-forming galaxies is significantly suppressed with respect to their counterparts in the field at a similar redshift. It is, however, highly uncertain which physical processes are responsible for this suppression. We present the results of a numerical investigation of how the global tidal field of a cluster dynamically influences the reservoir of halo gas surrounding a disk galaxy as it falls into the cluster from the surrounding field. We find that the tidal field of the cluster efficiently removes the halo gas from the galaxy, thereby halting its accretion onto the disk, and thus the fueling of star formation within. This effectively truncates the galaxy's star formation. We also find that this tidal truncation does not depend very strongly on the orbit of the disk with respect to the center of the cluster. These results suggest that the global tidal field of clusters is capable of causing a widespread and uniform suppression of star formation in galaxies accreted by the cluster. In light of these results, we discuss the importance of this tidal truncation of the gas supply in the formation of S0 galaxies in clusters.

description: We develop the Diakonov-Petrov approach to the representation of the non-Abelian Wilson loop in an Abelian form. First of all, we extend this approach to the Abelian representation of the parallel transporter corresponding to the open curve rather than to the closed contour. Next, we extend this representation to the case of the non-compact groups. The obtained expressions allow to derive the Abelian form of the Schwinger-Fock representation for the quark propagator in an external color gauge field.

description: We present the detection of a filament of Ly-alpha emitting galaxies in front of the quasar Q1205-30 at z=3.04 based on deep narrow band imaging and follow-up spectroscopy obtained at the ESO NTT and VLT. We argue that Ly-alpha selection of high redshift galaxies with relatively modest amounts of observing time allows the detection and redshift measurement of galaxies with sufficiently high space densities that we can start to map out the large scale structure at z=2-3 directly. Even more interesting is it that a 3D map of the filaments will provide a new cosmological test for the value of the cosmological constant, Omega_Lambda.

Excited States via Coupled Cluster Theory without Equation-of-Motion Methods: Seeking Higher Roots with Application to Doubly Excited States and Double Core Hole States

description: In this work, we revisited the idea of using the coupled-cluster ground state formalism to target excited states. Our main focus was targeting doubly excited states and double core hole states. Typical equation-of-motion (EOM) approaches for obtaining these states struggle without higher-order excitations than doubles. We showed that by using a non-aufbau determinant optimized via the maximum overlap method the CC ground state solver can target higher energy states. Furthermore, just with singles and doubles (i.e., CCSD), we demonstrated that the accuracy of $Δ$CCSD and $Δ$CCSD(T) far surpasses that of EOM-CCSD for doubly excited states. The accuracy of $Δ$CCSD(T) is nearly exact for doubly excited states considered in this work. For double core hole states, we used an improved ansatz for greater numerical stability by freezing core hole orbitals. The improved methods, core valence separation (CVS)-$Δ$CCSD and CVS-$Δ$CCSD(T), were applied to the calculation of the double ionization potential of small molecules. Even without relativistic corrections, we observed qualitatively accurate results with CVS-$Δ$CCSD and CVS-$Δ$CCSD(T). Remaining challenges in $Δ$CC include the description of open-shell singlet excited states with the single-reference CC ground state formalism as well as excited states with genuine multi-reference character. The tools and intuition developed in this work may serve as a stepping stone towards directly targeting arbitrary excited states using ground state CC methods.

The paper presents segments of the market for agritourism services in the opinions of survey respondents. According to university and secondary school students, most owners of agritourism farms promote their facilities on their own websites. In the opinion of secondary school students, service providers also promote their facilities on tourism fairs and in the traditional media. However, in the opinion of students entering higher education, as well as those who are prospective graduates, a very important way to promote an agritourism offer is the information transmitted in direct contacts. According to the respondents, families with children most often buy agritourism services.

description: Ensuring high quality and safety of food has become one of the priorities of the Common Agricultural Policy pursued both at the level of the European Union and individual Member States, including Poland. Consequently, among the measures in the Rural Development Programme for 2007-2013 was Measure 133 ‘Information and promotion activities’ designed to make consumers aware of the specificity of high-quality food products and to point out the benefits of consuming them. Its goal was to increase the demand for agricultural products and foodstuffs covered by food quality schemes and to broaden consumers’ knowledge of both the quality mechanisms and the advantages of the products covered by them. The article presents the results of a multidimensional analysis of financial support, which reveal the level of activity of agricultural producer groups in various Member States in procuring funds under Measure 133.

description: Management requirements for crop farming are high and will rise in the future. Arable farms are challenged by volatile markets, growing administrative burdens, increasing operating costs and growing competition for land. Management skills have become much more important for farmers in recent years and this trend will continue in the future. There are numerous instruments like accounting software or crop field cards integrated in daily management practice, but there is a deficiency of a fully integrated management system to give an overview of all areas of the farming business. This gap can be closed by the management tool Balanced Scorecard (BSC) that provides an overview of all production and management activities on a farm. Therefore, with the aim to trans-fer the BSC concept to crop farming, German farmers and agricultural advisors were surveyed to get insights into the success factors and key performance indicators in the four BSC perspectives they consider most rele-vant for the operational success of arable farms. By the use of a cluster analysis, three different farm types were identified according to their visions and strategies. For the three farm types the key performance indica-tors that the respondents considered most relevant for farm performance were figured out. Implementation of the BSC to crop farming can result in a big benefit for management practice. The BSC focuses vision and long-term strategy with the main goal to ensure consistency of the farm and increase farm performance.

description: Der 26. Band der Jahrbuch-Reihe des Deutschen Polen-Instituts widmet sich einem Thema, das aktueller nicht sein könnte: der Umwelt. Die Notwendigkeit des Umweltschutzes und des Verzichts auf konventionelle Energieträger, in Deutschland mittlerweile weitgehend anerkannt, ist in Polen nach wie vor Gegenstand hitziger Debatten. Es überrascht nicht bei einem Land, das knapp 90 Prozent seines Stroms in Stein- und Braunkohlekraftwerken produziert (S. 34) und in dem der Bergbau immer noch als traditionsreicher Stolz der Nation gilt. Mittlerweile gerät Polen aber unter zunehmenden Druck seitens der Europäischen Union und der eigenen Bürgerinnen und Bürger und kann die Dringlichkeit des Themas nicht länger ignorieren. Zu einem solchen Zeitpunkt erschienen, erweist sich das Jahrbuch als eine hilfreiche Übersicht. Es setzt sich zum Ziel, die in Polen herrschenden Debatten wiederzugeben (auch durch Beiträge der an ihnen beteiligten Akteure), in einem breiteren Kontext zu verorten und für deutschsprachige Leser zugänglicher zu machen – so die Redakteure Andrzej Kałuża und Jutta Wierczimok.

Knowledge to develop this model and a proof of concept is obtained by case study research focusing on the collaborative Business Processes of spraying and crop protection of potatoes against late blight disease. need to collaborate with numerous actors that are part of Agri-Food Supply Chain Networks (AFSCNs) such as governments, advisory services, contractors, processors, input providers and certification bodies. This collaboration is required to produce food in a more sustainable, safe and transparent manner. To collaborate efficiently and effectively, information needs to be shared within collaborative Business Processes. The information sharing within such collaborative Business Processes should be supported by an ICT infrastructure consisting of interoperable ICT Components. Currently, most of the available ICT Components are not interoperable, hindering data exchange between ICT Components of various vendors. Consequently, this situation is hindering optimization of farm production processes and collaboration in AFSCNs. Therefore, a platform, called FIspace, is being established for multiple domains that support the development and configuration of interoperable ICT Components into a system that is able to support collaborative farm Business Processes. To develop interoperable ICT Components and configure these in an easy and flexible manner to support farm enterprises, a farm information model is, amongst other models, required.The presented farm information reference model is able to describe the relations between a farm enterprise and its collaborators, the Business Processes related to the supporting ICT Components and the data messages for data exchange between ICT Components.

description: The variation of energy prices has been a traditional source of shocks to the real economy. In many cases, this variation has manifested in jumps in energy prices that were characterized by some persistence. From another perspective, energy price volatility has historically been noted and its effects on real economy debated. Historically, the importance of the shocks to the real economy has led them to be labeled as energy crises, as they were argued to have resulted in substantial changes in real prices that induced changes in behavior on the demand and supply sides of the many markets. However, empirical studies of transmission of energy prices into the real economy have produced no consensus and have been challenged by a number of significant specification issues that have resulted in substantial variation in inference drawn from results. Among these issues is the question of completeness of model specification. This paper examines the question of whether such models need to incorporate macroeconomic indicators. Clearly, macroeconomic factors such as interest rates and exchange rates play a role in the determination of energy and commodity prices, however, considerable specification uncertainty characterizes the question of which macro metrics to incorporate. This paper examines this issue from the perspective of weak exogeneity and finds evidence that the parameter estimates associated with time series models that exclude consideration of macro indicators are not compromised by their exclusion. We examine this issue using Italian, U.S. grain, and Brent crude oil prices.

description: In this paper we construct certain moduli spaces, which we call moduli spaces of (principal) $F$-bundles, and study their basic properties. These spaces are associated to triples consisting of a smooth projective geometrically connected curve over a finite field, a split reductive group $G$, and an irreducible algebraic representation $\ov{\om}$ of $(\check{G})^n/Z(\check{G})$. Our spaces generalize moduli spaces of $F$-sheaves, studied by Drinfeld and Lafforgue, which correspond to the case $G=GL_r$ and $\ov{\om}$ is the tensor product of the standard representation and its dual. The importance of the moduli spaces of $F$-bundles is due to the belief that Langlands correspondence should be realized in their cohomology.

description: Chemical pressure is an effective method to tune physical properties, particularly for diluted magnetic semiconductors (DMS) of which ferromagnetic ordering is mediated by charge carriers. Via substitution of smaller Ca for larger Sr, we introduce chemical pressure on (Sr,Na)(Cd,Mn)2As2 to fabricate a new DMS material (Ca,Na)(Cd,Mn)2As2. Carriers and spins are introduced by substitutions of (Ca,Na) and (Cd,Mn) respectively. The unit cell volume reduces by 6.2% after complete substitution of Ca for Sr, suggesting a subsistent chemical pressure. Importantly the local geometry of [Cd/MnAs4] tetrahedron is optimized via chemical compression that increases the Mn-As hybridization leading to enhanced ferromagnetic interactions. As a result, the maximum Curie temperature (TC) is increased by about 50% while the the maximum saturation moment increases by over 100% from (Sr,Na)(Cd,Mn)2As2 to (Ca,Na)(Cd,Mn)2As2. The chemical pressure estimated from the equation of state is equal to an external physical pressure of 3.6 GPa.

description: Recent spectroscopic and morphological observational studies of galaxies around NGC 1399 in the Fornax Cluster (Drinkwater et al. 2000b) have discovered several `ultra-compact dwarf' galaxies with intrinsic sizes of $\sim$ 100 pc and absolute $B$ band magnitudes ranging from -13 to -11 mag. In order to elucidate the origin of these enigmatic objects, we perform numerical simulations on the dynamical evolution of nucleated dwarf galaxies orbiting NGC 1399 and suffering from its strong tidal gravitational field. Adopting a plausible scaling relation for dwarf galaxies, we find that the outer stellar components of a nucleated dwarf are totally removed. This is due to them being tidally stripped over the course of several passages past the central region of NGC 1399. The nucleus, however, manages to survive. We also find that the size and luminosity of the remnant are similar to those observed for ultra-compact dwarf galaxies, if the simulated precursor nucleated dwarf has a mass of $\sim$ $10^8$ $M_{\odot}$. These results suggest that ultra-compact dwarf galaxies could have previously been more luminous dwarf spheroidal or elliptical galaxies with rather compact nuclei.

description: The Polish historian Maciej Górny has set his sights on describing the involvement of Central-Eastern European and Balkan intellectuals in the First World War. His book, entitled Wielka Wojna profesorów (The Great War of the Professors), is devoted to this issue. As it turns out, historians have already given much attention to this so-called "war of spirit" („Krieg der Geister"); however, they have so far concentrated on the involvement of Western European scientists. Górny claims that there is a significant gap in this scope and the possibility to compare successfully intellectuals from the Balkans, Central Europe, and Eastern Europe makes this gap even greater. The scientific as well as social status of such intellectuals, related mainly to public respect, allows for such a comparative analysis.

description: NLTE line formation calculations of FeI in the solar atmosphere are extended to include weak optical lines. Previously established atomic models are used to discriminate between different ways of treating collisional interaction processes. To derive a common solar FeI abundance from both strong and weak lines, fine-tuning of the microturbulence velocity parameter and the van-der- Waals damping constants is required. The solar FeI abundances based on all available f-values are dominated by the large scatter already found for the stronger lines. In particular the bulk of the data from the work of May et al. and O'Brian et al. is not adequate for accurate abundance work. Based on f-values measured by the Hannover and Oxford groups alone, the FeI LTE abundances are eps(FeI,Sun)=7.57 for the empirical and eps(FeI,Sun) = 7.48 ... 7.51 for the line-blanketed solar model. The solar Fe ionization equilibrium obtained for different atomic and atmospheric models rules out NLTE atomic models with a low efficiency of hydrogen collisions. At variance with Paper I, it is now in better agreement with laboratory FeII f-values for all types of line-blanketed models. Our final model assumptions consistent with a single unique solar Fe abundance eps(Fe,Sun) = 7.48 ... 7.51 calculated from NLTE line formation are (a) a line-blanketed solar model atmosphere, (b) an iron model atom with hydrogen collision rates 0.5 < S_H < 5 times the standard value to compensate for the large photoionization cross-sections, (c) a microturbulence velocity xi = 1.0 kms, (d) van-der-Waals damping parameters decreased by Delta(log C6) = -0.10...-0.15 as compared to Anstee & O'Mara's calculations, depending on S_H, (e) FeII f-values as published by Schnabel et al., and (f) FeI f-values published by the Hannover and Oxford groups.

description: a theoretic level, price transmission does not provide a clear signal of competitiveness as many conditions may induce stickiness and even asymmetry in the speed of adjustment to positive and negative changes. While evidence from past EU studies for the dairy sector is mixed, several studies have found evidence of asymmetry in particular countries. However, none to our knowledge have considered evidence for Italy. We examine price dynamics within the chain and test for presence of asymmetry in the transmission of price changes along the chain. Using a parametric test of asymmetry in a multivariate VECM, we find strong evidence of symmetry in co-movement. To explore whether these results are robust with respect to nonlinearity we estimate threshold VECM models and also find strong evidence to reject asymmetry except for the transmission between raw milk and wholesale butter prices. While inference with respect to competitiveness of markets cannot be inferred from evidence of asymmetry, findings of symmetry confirm that the market organization and performance is not controlling price change to be asymmetric.

description: Two-dimensional transition metal dichalcogenide (2D-TMD) monolayers, which reveal remarkable semiconductor properties, are the subject of active experimental research.Recently it has been shown experimentally that quantum yield in MoS2 and WSe2 monoatomic layers can reach values close to unity when electrostatic doping makes them intrinsic semiconductors. However, the available theoretical description does not give an understanding of the physical mechanisms underlying in the gate voltage control of quantum yield.This work is an attempt to propose a consistent semi-phenomenological theory of photo-induced charge carriers relaxation in 2D-TMDs, which allows obtaining an analytical dependence of the quantum yield on the voltage applied to the FET gate. We consider a standard experimental situation, when the 2D-TMD monolayer and the metal gate are plates of a flat capacitor, and the capacitor charge is proportional to the gate voltage. The dependences of the TMD monolayers quantum yield on the gate voltage and the carrier generation rate have been calculated for the cases of the prevailing recombination of free electrons and holes (radiative and non-radiative Auger recombination) and recombination of excitons (radiative and Auger recombination). In both cases analytical expressions were derived for the dependence of quantum yield on the gate voltage and photo-induced carriers generation rate at a fixed gate voltage. Quantitative agreement with experiment allows concluding about the relevance of the proposed theoretical model for the description of carriers photo-generation and recombination in 2D-TMD monolayers. Obtained results demonstrate the possibilities of 2D-TMD quantum yield control by the gate voltage and indicate that 2D-TMDs are promising candidates for modern optoelectronics devices.

On the "equivalence" of the Maxwell and Dirac equations

Publisher: name: arXiv
Year: 2002
Subjects: subject: Mathematical Physics (math-ph)

description: It is shown that Maxwell's equation cannot be put into a spinor form that is equivalent to Dirac's equation. First of all, the spinor ψin the representation \vec{F} = ψ\vec{u} \barψ of the electromagnetic field bivector depends on only three independent complex components whereas the Dirac spinor depends on four. Second, Dirac's equation implies a complex structure specific to spin 1/2 particles that has no counterpart in Maxwell's equation. This complex structure makes fermions essentially different from bosons and therefore insures that there is no physically meaningful way to transform Maxwell's and Dirac's equations into each other.

description: We present a measurement of CP-violation parameters in the b->sq q penguin transitions (q=s,u,d) based on a 78/fb data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is reconstructed in the phiks, K+K-ks, or eta'ks decay channel, and the flavor of the accompanying B meson is identified from its decay products. CP violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.

description: Gdy słyszę słowo „leksykon" kojarzę je z alfabetycznie uszeregowanym ciągiem haseł. Jego rolą jest wyjaśnianie znaczenia, dosłownego, ale i przenośnego. Nie można tej definicji zastosować do „Leksykonu mitów, symboli…", o którym tu mowa. Jest to raczej, jak piszą jego redaktorzy, „Handbuch, co znowu w niezbyt ścisłym tłumaczeniu na język polski odpowiada terminowi podręcznik". Podkreślają przy tym, że ich życzeniem byłoby, „by oddawana do rąk Czytelników książka znalazła się w bibliotece podręcznej każdego humanisty zajmującego się Górnym Śląskiem" (s. 11). Biorąc pod uwagę wyjątkowe znaczenie tej pracy, jej stosunkowo niewielki nakład (1 200 egz.) powinien być od dawna wyczerpany.
