description: The Lagrangian of pseudoscalar, vector, and axial-vector mesons is determined by the explicit global chiral symmetry and hidden local chiral symmetry. There are fourteen interacting terms up to the dimension-four of covariant derivatives rather than the usual eleven interacting terms given in literature from hidden local symmetry approach. There are only two independent parameters. The three new terms are important in phenomenology.

description: We have reexamined the holographic dark energy model by considering the spatial curvature. We have refined the model parameter and observed that the holographic dark energy model does not behave as phantom model. Comparing the holographic dark energy model to the supernova observation alone, we found that the closed universe is favored. Combining with the Wilkinson Microwave Anisotropy Probe (WMAP) data, we obtained the reasonable value of the spatial curvature of our universe.

Statistical models of diffusion and aggregation for coke formation in a catalyst pore

description: We simulated models of diffusion and aggregation in long pores of small widths in order to represent the basic mechanisms of coke deposition in catalysts' pores. Coke precursors are represented by particles injected at the pore entrance. Knudsen diffusion, which is usually expected inside the pores, is modeled by ballistic motion of those particles. The regime of molecular diffusion is also analyzed via models of lattice random walks biased along the pores. The aggregation at the surface or near previously aggregated particles was modeled by different probabilistic rules, accounting for the possibilities of more compact or more ramified deposits. In the model of Knudsen diffusion and in some cases of molecular diffusion, there is an initial regime of uniform deposition along the pore, after which the deposits acquire an approximately wedge shape, with the pore plugging near its entrance. After the regime of uniform deposition and before that of critical pore plugging, the average aggregation position slowly decreases with the number N of deposited particles approximately as N^{-0.25}. The apparently universal features of deposits generated by microscopic models are compared with those currently adopted in continuum models.

Melting driven by rotating Rayleigh-Bénard convection

description: We study numerically the melting of a horizontal layer of a pure solid above a convecting layer of its fluid rotating about the vertical axis. In the rotating regime studied here, with Rayleigh numbers of order $10^7$, convection takes the form of columnar vortices, the number and size of which depend upon the Ekman and Prandtl numbers, as well as the geometry -- periodic or confined. As the Ekman and Rayleigh numbers vary, the number and average area of vortices vary in inverse proportion, becoming thinner and more numerous with decreasing Ekman number. The vortices transport heat to the phase boundary thereby controlling its morphology, characterized by the number and size of the voids formed in the solid, and the overall melt rate, which increases when the lower boundary is governed by a no-slip rather than a stress-free velocity boundary condition. Moreover, the number and size of voids formed are relatively insensitive to the Stefan number, here inversely proportional to the latent heat of fusion. For small values of the Stefan number, the convection in the fluid reaches a slowly evolving geostrophic state wherein columnar vortices transport nearly all the heat from the lower boundary to melt the solid at an approximately constant rate. In this quasi-steady state, we find that the Nusselt number, characterizing the heat flux, co-varies with the interfacial roughness, for all the flow parameters and Stefan numbers considered here. This confluence of processes should influence the treatment of moving boundary problems, particularly those in astrophysical and geophysical problems where rotational effects are important.

We find no evidence of a disagreement between the OPAL data and the LEP Energy Workings Group's standard calibration. Including the energy- averaged 11 MeV uncertainty in the standard determination, the beam energy we obtain from the OPAL data is higher than that obtained from the LEP calibration by 0+-34(stat.)+-27(syst.)MeV

description: With the inevitable dominance of video traffic on the Internet, providing perceptually good video quality is becoming a challenging task. This is partly due to the bursty nature of video traffic, changing network conditions and limitations of network transport protocols. This growth of video traffic has made Quality of Experience (QoE) of the end user the focus of the research community. In contrast, Internet service providers are concerned about maximizing revenue by accepting as many sessions as possible, as long as customers remain satisfied. However, there is still no entirely satisfactory admission algorithm for flows with variable rate. The trade-off between the number of sessions and perceived QoE can be optimized by exploiting the bursty nature of video traffic. This paper proposes a novel algorithm to determine the upper limit of the aggregate video rate that can exceed the available bandwidth without degrading the QoE of accepted video sessions. A parameter $β$ that defines the exceedable limit is defined. The proposed algorithm results in accepting more sessions without compromising the QoE of on-going video sessions. Thus it contributes to the optimization of the QoE-Session trade-off in support of the expected growth of video traffic on the Internet.

description: A Dél-Alföld egyik problémája abban rejlik, hogy viszonylag kevés az egységes arculatot meghatározó, széles körben ismert egyedi termék, és ezek is egymástól elszigetelten léteznek. Ugyanakkor számos olyan, a régióban előállított hungarikum létezik, amelyek alkalmasak a helyi hagyományok megőrzésére, a régió imá¬zsának kialakítására. Ezen termékek körének kiválasztása, menedzselése, védelme az aktív marketingpolitika eszközével hozzájárulhat a Dél-Alföldről kialakított kép pozitív irányú befolyásolásához. Elősegítik a specializált termőkörzetek stabilizációját, a helyi gazdaság megerősödését és az ott élők jövedelmi viszonyainak javulását. A Dél-alföldi Régió marketingstratégiájának kulcsfontosságú elemei lehetnek azok a régióspecifikus termékek (pl. Kecskeméti barackpálinka), amelyek a szigorú előírásoknak és elvárásoknak megfelelnek. Fontos, hogy a Régió egyedi termékei igazi hungarikumok maradjanak, és a védjegyek mögött állandó, garantált minőség jelenjen meg. Ebben a munkában a Szegedi fűszerpaprika és a hungarikum pálinkák marketingelemzésére vállalkoztunk SWOT analízis, mélyinterjúk és imázsprofil-vizsgálatokkal. ------------------------------------------- One issue the Southern Great Plain region has to face is that is has relatively few well-known characteristic products and that the ones which do exist are isolated from one another. There are however several Hungaricum products made in the region which can be used to keep local traditions alive and to give an image to the region. Active use of marketing tools in selecting, managing and protecting these products can contribute to improving how the Southern Great Plain region is seen by the world. It may promote the stabilisation of producer districts, the strengthening of local economy, and may bring an improvement in the revenues of local residents. Products which are specific to the region and meet strict requirements and standards (such as the Kecskeméti apricot brandy) may be the key components in the marketing strategy for the Southern Great Plain region. It is important to ensure that products unique to the region remain true Hungaricums and that the trademarks always mean a uniformly high quality. This papers covers our marketing analysis of the Szegedi Ground Red Pepper and Hungaricum brandies by way of a SWOT analysis, deep interviews and image profile analyses.

Here we point out that a key part of this proof may be replaced by an argument of Russo from 1982, using his approximate zero-one law in place of the Friedgut-Kalai result. Russo's paper gave a new proof of the Harris-Kesten Theorem that seems to have received little attention.

A becsült meteorológiai jellemzők átlagosan nem mutatnak nagy változást a közeljövőre – jóllehet a század végére már igen –, de eloszlásuk alakulása a mezőgazdaságban komoly következményekkel járhat. A növény szempontjából azonban az éves és havi átlaghőmérséklet, illetve csapadékösszegek elemzése helyett sokkal több információhoz juthatunk, ha a növény fejlődési szakaszait külön-külön vizsgáljuk. Végigkövetve a növény fejlődési szakaszait megállapítható, hogy az őszi árpa klimatikus igényei várhatóan a jövőben is teljesülnek, jóllehet a termésbiztonság ezzel együtt romlani fog. ---------------------------------------- This paper covers comparative studies on the climatic needs of autumn barley in its individual development stages. The estimated average meteorology characteristics are not expected to change greatly in the near future – not until the end of the century - but changes in their distribution may have serious consequences for agriculture. For many plants, examining its needs in the various development stages separately is much more informative than examining its needs in terms of annual and monthly average temperature and precipitation levels. Monitoring the development stages of autumn barley leads to the conclusion that its climatic needs will most probably be still met in the future, although reliability of crop production will be compromised.

description: Using a nonperturbative weak noise approach we investigate the interference of noise and chaos in simple 1D maps. We replace the noise-driven 1D map by an area-preserving 2D map modelling the Poincare sections of a conserved dynamical system with unbounded energy manifolds. We analyze the properties of the 2D map and draw conclusions concerning the interference of noise on the nonlinear time evolution. We apply this technique to the standard period-doubling sequence in the logistic map. From the 2D area-preserving analogue we, in addition to the usual period-doubling sequence, obtain a series of period doubled cycles which are elliptic in nature. These cycles are spinning off the real axis at parameters values corresponding to the standard period doubling events.

description: For the purpose of acquiring a highly active producer of pectolytic enzymes, there was a probe of isolating 140 species of Aspergillus’s fungi from different substrates (soils, grape malts, grapes, apples and sugar beet shreds). The isolated kinds of fungi were kept on a slant agar surface according to Chapek, with 2% of pectin. Testing was performed on the isolated layers of fungi as to the production of pectinolytic enzymes. The nourishing base used was the synthetic Chapek base with 2% pectin, 2% lactose and 0.7 % (NH4)2HPO4, and a natural base of 1% refuse apple pulp. Within 48 hours after cultivating the fungi, the filtrates were tested by the viscozimetric method to determine their entire pectolytic activity. The acquired results showed that a fungus was gained with a high pectolytic activity on a natural refuse apple pulp. It is a good employment effect. The selected sort Aspergillus sp.МК-15 as a highly active producer of pectolytic enzymes could, with additional testing, be used for the industrial production of microbe enzymes with pectolytic activity (enzyme preparations).

description: This interdisciplinary paper uses world-systems analysis as a theoretical framework to argue that both the 1870s, 1930’s economic depressions reduced mean global temperatures. As global consumer demand fell, factories worldwide began producing less commodities and, as a result, emitted less greenhouse gasses. We find that in both instances there is evidence to support the hypothesis that financial crises lead to cooler temperatures.

Small glitches and other rotational irregularities of the Vela pulsar

description: Glitches are sudden increases in the rotation rate $ν$ of neutron stars, which are thought to be driven by the neutron superfluid inside the star. The Vela pulsar presents a comparatively high rate of glitches, with 21 events reported since observations began in 1968. These are amongst the largest known glitches (17 of them have sizes $Δν/ν\geq10^{-6}$) and exhibit very similar characteristics. This similarity, combined with the regularity with which large glitches occur, has turned Vela into an archetype of this type of glitching behaviour. The properties of its smallest glitches, on the other hand, are not clearly established. High-cadence observations of the Vela pulsar were taken between 1981 and 2005 at the Mount Pleasant Radio Observatory. An automated systematic search was carried out that investigated whether a significant change of spin frequency $ν$ and/or the spin-down rate $\dotν$ takes place at any given time. We find two new glitches, with respective sizes $Δν/ν$ of $(5.55\pm0.03)\times10^{-9}$ and $(38\pm4)\times10^{-9}$. In addition to these two glitch events, our study reveals numerous events of all possible signatures (i.e. combinations of $Δν$ and $Δ\dotν$ signs), all of them small with $|Δν|/ν<10^{-9}$, which contribute to the Vela timing noise. The Vela pulsar presents an under-abundance of small glitches compared to many other glitching pulsars, which appears genuine and not a result of observational biases. In addition to typical glitches, the smooth spin-down of the pulsar is also affected by an almost continuous activity that can be partially characterised by small step-like changes in $ν$, $\dot{ν,}$ or both. Simulations indicate that a continuous wandering of the rotational phase, following a red spectrum, could mimic such step-like changes in the timing residuals.

description: The spatial and kinematic properties of a large sample of young T Tauri stars from the solar neighborhood 500 pc in radius have been studied. The following parameters of the position ellipsoid have been determined from the most probable members of the Gould Belt: its sizes are $350\times 270 \times 87$~pc and it is oriented at an angle of $14\pm1^\circ$ to the Galactic plane with a longitude of the ascending node of $297\pm1^\circ$. An analysis of the motions of stars from this sample has shown that the residual velocity ellipsoid with principal semiaxes $σ_{1,2,3}=(8.87,5.58,3.03)\pm(0.10,0.20,0.04)$~km s$^{-1}$ is oriented at an angle of $22\pm1^\circ$ to the Galactic plane with a longitude of the ascending node of $298\pm2^\circ$. It has been established that much of the expansion effect (kinematic $K$ effect) typical for Gould Belt stars, 5--6 km s$^{-1}$ kpc$^{-1}$, can be explained by the influence of a Galactic spiral density wave with a radial perturbation amplitude $f_R\sim5$ km s$^{-1}$.

The effects of two paradigms of intermittent hypoxia on human cardio-ventilatory responses and cerebral tissue oxygenation
Creators: name: Foster, Glen Edward
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to determine the ventilatory, cardiovascular, and cerebral tissue oxygen responses to two paradigms of normobaric, isocapnic, intermittent hypoxia (IH). Eighteen male subjects were randomly assigned to one of two IH groups; short duration IH (SDIH) was exposed to 5 minutes of 12% O₂ separated by 5 minutes of normoxia for one hour, and long duration IH (LDIH) was exposed to 30 minutes of 12% O₂. Both groups had 10 daily exposures over a twelve day period. The isocapnic hypoxic ventilatory response was measured before (preHVR) and after (postHVR) each daily exposure on day 1, 3, 5, 8, 10, 12 and again 3 and 5 days following the end o f IH. The hyperoxic hypercapnic ventilatory response (HCVR) was determined following rest on days 1, 12, 15, and 17. During all procedures, ventilation, beat-by-beat blood pressure, heart rate (HR) arterial oxyhemoglobin saturation (SaO₂), and cerebral tissue oxygenation (SCO₂) were measured. The preHVR increased throughout IH exposure regardless o f paradigm and returned to resting levels by day 17 (Day 1: 0.84 ± 0.50; Day 12: 1.20 ± 1.01; Day 17: 0.95 ± 0.58 1 min⁻¹ %SaO₂⁻¹; p= 0.002). The H C V R did not change throughout IH. The postHVR was blunted compared with the preHVR (p= 0.02). There were no differences in the change in systolic blood pressure sensitivity (ΔSBP/ΔSaO₂), diastolic blood pressure sensitivity (ΔDBP/ΔSaO₂), heart rate sensitivity (ΔHR/ΔSaO₂), cardiac output sensitivity (ΔCO/ΔSaO₂), stroke volume sensitivity (ΔSV/ΔSaO₂), and total peripheral resistance sensitivity (ΔTPR/ΔSaO₂) to hypoxia following IH. The change in cerebral tissue oxygen saturation sensitivity to hypoxia (ΔScO₂/ΔSaO₂) was less on day 12 (Day 1: -0.51 ± 0.13; Day 12: -0.64 ± 0.181 p= 0.0002) and the change in cerebral tissue deoxyhemoglobin concentration (ΔHHb/ΔSaO₂) was more on day 12 (Day 1: 0.34 ± 0.21; Day 12: 0.44 ± 0.14 uM %SaO₂⁻¹; p= 0.007). These differences had returned to baseline by day 17. Acute exposure to SDIH increased mean arterial pressure (MAP; p= 0.005) but LDIH did not (p>0.05). Intermittent hypoxia did not improve exercise ventilatory efficiency during exercise. In conclusion, exposures to SDIH and LDIH have similar effects on the ventilatory, cardiovascular, and cerebral oxygen responses to acute progressive hypoxia. However, acute exposure to SDIH increases MAP while LDIH does not.

description: The minimal work principle states that work done on a thermally isolated equilibrium system is minimal for adiabatically slow (reversible) realization of a given process. This principle, one of the formulations of the second law, is studied here for finite (possibly large) quantum systems interacting with macroscopic sources of work. It is shown to be valid as long as the adiabatic energy levels do not cross. If level crossing does occur, counter examples are discussed, showing that the minimal work principle can be violated and that optimal processes are neither adiabatically slow nor reversible. The results are corroborated by an exactly solvable model.

description: For any $Ω\subset \mathbb{R}^N$ smooth and bounded domain, we prove uniqueness of positive solutions of free boundary problems arising in plasma physics on $Ω$ in a neat interval depending only by the best constant of the Sobolev embedding $H^{1}_0(Ω)\hookrightarrow L^{2p}(Ω)$, $p\in [1,\frac{N}{N-2})$ and show that the boundary density and a suitably defined energy share a universal monotonic behavior. At least to our knowledge, for $p>1$, this is the first result about the uniqueness for a domain which is not a two-dimensional ball and in particular the very first result about the monotonicity of solutions, which seems to be new even for $p=1$. The threshold, which is sharp for $p=1$, yields a new condition which guarantees that there is no free boundary inside $Ω$. As a corollary, in the same range, we solve a long-standing open problem (dating back to the work of Berestycki-Brezis in 1980) about the uniqueness of variational solutions. Moreover, on a two-dimensional ball we describe the full branch of positive solutions, that is, we prove the monotonicity along the curve of positive solutions until the boundary density vanishes.

description: The research aims to investigate the process of globalizing innovation activity conducted by transnational corporations (TNCs), in a wider context of economic changes outside and inside companies. The process has been triggered by decentralization and internationalization of R&D, “creative transition” of foreign subsidiaries as well as implementing research networks and the open innovation model of TNCs’ innovation activity. Under the present economic crisis some slowdown and reorientation of innovation programs are implemented in order to reduce their costs and increase effectiveness. The globalization of corporate innovation activity can contribute to reaching some of TNCs’ goals both under the present crisis and the future revival of the world economy.

description: We consider the strongly convergent modified versions of the Krasnosel'ski\uı-Mann, the forward-backward and the Douglas-Rachford algorithms with Tikhonov regularization terms, introduced by Radu Boţ, Ernö Csetnek and Dennis Meier. We obtain quantitative information for these modified iterations, namely rates of asymptotic regularity and metastability. Furthermore, our arguments avoid the use of sequential weak compactness and use only a weak form of the projection argument.

Device-independent quantum key distribution with asymmetric CHSH inequalities
Creators: name: Woodhead, Erik

Subjects: subject: Quantum Physics (quant-ph)

description: The simplest device-independent quantum key distribution protocol is based on the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality and allows two users, Alice and Bob, to generate a secret key if they observe sufficiently strong correlations. There is, however, a mismatch between the protocol, in which only one of Alice's measurements is used to generate the key, and the CHSH expression, which is symmetric with respect to Alice's two measurements. We therefore investigate the impact of using an extended family of Bell expressions where we give different weights to Alice's measurements. Using this family of asymmetric Bell expressions improves the robustness of the key distribution protocol for certain experimentally-relevant correlations. As an example, the tolerable error rate improves from 7.15% to about 7.42% for the depolarising channel. Adding random noise to Alice's key before the postprocessing pushes the threshold further to more than 8.34%. The main technical result of our work is a tight bound on the von Neumann entropy of one of Alice's measurement outcomes conditioned on a quantum eavesdropper for the family of asymmetric CHSH expressions we consider and allowing for an arbitrary amount of noise preprocessing.

description: The growing importance and scope of technology transfer processes undertaken all over the world settles the question of the necessity for their proper identification. The multi-aspect character and complexity of these phenomena create specific problems in conducting analytic work. Although technology transfer is an element of the Science-Technology-Innovation (STI) system, it does not have a proper place in the existing methodology system of this area. The aim of this article is to point out the necessity to create a proper, complex and comprehensive methodology for researching technology transfer processes, which would contribute to better understanding of the processes themselves and at the same time enable their proper development.

description: Hypothesis: New dynamic phenomena can be observed in evaporating free liquid films from colloidal solutions with bimodal particle size distribution. Such distributions are formed in a natural way in mixed (slightly turbid) solutions of cationic and anionic surfactants, where nanosized micelles coexist with micronsized precipitated particles. Experiment: Without evaporation of water, the films thin down to thickness < 100 nm. Upon water evaporation from the film, one observes spontaneous film thickening (above 300 nm) and appearance of a dynamic vortex with a spot of thinner film in the center. The vortex wall has a stepwise profile with step-height equal to the effective micelle diameter (ca. 8 nm) and up to 20-30 stratification steps. Results: For thicknesses greater than 100 nm, stratification in foam films from micellar solutions has never been observed so far. It evidences for the formation of a thick colloidal crystal of micelles in the evaporating film. The role of the bigger, micronsized particles is to form a filtration cake in the Plateau border, which supports the thick film. The developed quantitative mechanical model shows that the stepwise vortex profile is stabilized by the balance of hydrodynamic and surface tension forces. Vortex is observed not only in films from catanionic surfactant solutions, but also in films from silica and latex particle suspensions, which contain smaller surfactant micelles.

Ausmaß und Determinanten von Preisrigiditäten im deutschen Lebensmitteleinzelhandel - Eine emprische Analyse mit Scannerdaten

description: Analyses of price rigidity mainly neglected food retailing industry. There are only few studies explicitly concerning this part of the food process chain. In Blinder’s et al. (1998) analysis of the U.S. economy the food retailing industry is underrepresented, whereas for Germany this industry is not even considered by Stahl (2005) at all, who concentrates his survey on manufacturing industries. An aggravating factor is that most of the remaining studies cover only few determinants for price rigidity’s explanation. On the basis of an extensive scanner dataset the present analysis simultaneously elucidates price rigidity with different determinants in the category of hard and sliced cheese for the year 2000 and 2001. Here, psychological pricing points, the average absolute amount of a price change as a proxy for menu costs, and the short-run price elasticity of demand as well as management decisions at the level of store types and firms are considered to be the main driving factors of price rigidity. It is novel in this study that price changes are divided into price actions (sales) and market driven price changes (price jumps). For estimation Zellner’s (1962) method of the Seemingly-Unrelated-Regression (SUR) is applied. This procedure is particularly suitable due to the direct and indirect impacts of the relevant determinants on the rigidity of prices, because determinant’s cross-relations are detected and modeled. The model results document that price rigidity differs clearly between sales and price jumps. Whereas in an overall view of all price changes price rigidity varies at the level of store types (firms) between 24.1 and 35.5 (11.0 and 10.7) weeks, considering only sales the duration of constant prices increases to periods ranging from 72.3 to 87.3 (38.8 to 89.2) weeks. Price jumps can be observed more frequently, so that the mean period of constant prices ranges between 32.0 and 44.0 (27.7 to 95.3) weeks at the level of store types (firms). The direct effect of an additional price action (price jump) on price rigidity is -1.5 (- 9.0) weeks for store types and -1.7 (- 10.0) weeks for firms. The influence of psychological prices on the price rigidity can be documented likewise. An increase of the share of psychological prices of sales by one percentage point implies, e.g. at the level of firms, that the duration of constant prices is raised by 1.3 weeks.

description: Agriculture in Slovenia is characterized by less-favourable natural and structural conditions. The degree of competitiveness of the whole agro-food sector will eventually decide whether farmers and industry will be able to compete on the EU market. Slovenian agriculture at the moment still lacks competitiveness Farmers that want to stay into business will have to further develop their farm. For farm development, besides craftsmanship and management skills increasingly entrepreneurial competencies are needed. To get insight into the entrepreneurial characteristics of Slovenian dairy farmers by investigating the opportunities and threats as perceived by farmers (external factors) to establish a future in rural Slovenia in the relation to internal factors (farmers’ and farm characteristics) and future strategy of the farmer.
Deep Learning Techniques to make Gravitational Wave Detections from Weak Time-Series Data

description: Gravitational waves are ripples in the space time fabric when high energy events such as black hole mergers or neutron star collisions take place. The first Gravitational Wave (GW) detection (GW150914) was made by the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo Collaboration on September 14, 2015. Furthermore, the proof of the existence of GWs had countless implications from Stellar Evolution to General Relativity. Gravitational waves detection requires multiple filters and the filtered data has to be studied intensively to come to conclusions on whether the data is a just a glitch or an actual gravitational wave detection. However, with the use of Deep Learning the process is simplified heavily, as it reduces the level of filtering greatly, and the output is more definitive, even though the model produces a probabilistic result. Our technique, Deep Learning, utilizes a different implementation of a one-dimensional convolutional neural network (CNN). The model is trained by a composite of real LIGO noise, and injections of GW waveform templates. The CNN effectively uses classification to differentiate weak GW time series from non-gaussian noise from glitches in the LIGO data stream. In addition, we are the first study to utilize fine-tuning as a means to train the model with a second pass of data, while maintaining all the learned features from the initial training iteration. This enables our model to have a sensitivity of 100%, higher than all prior studies in this field, when making real-time detections of GWs at an extremely low Signal-to-noise ratios (SNR), while still being less computationally expensive. This sensitivity, in part, is also achieved through the use of deep signal manifolds from both the Hanford and Livingston detectors, which enable the neural network to be responsive to false positives.
