Year: 1953

description: 1. Von dem zuerst 1907 von Menzel beschriebenen, vor kurzem (1951) auch von P. W. Thomson pollenanalytisch untersuchten Interglazial von Wallensen wurden noch 3 weitere Diagramme aufgestellt, ein Profil und über 50 Einzelproben auf Großreste untersucht. Die nachgewiesene Folge der Waldperioden: 5. Kiefern-Eichenmischwaldzeit — 6. Hasel-Eichenmischwaldzeit — 7. Hainbuchenzeit — 8. Tannenzeit — 9. Fichtenzeit — 10. Kiefernzeit, stimmt — mutatis mutandis — völlig mit der Periodenfolge überein, die in Dänemark und im nordwestdeutschen Flachland als für das letzte Interglazial bezeichnend erkannt worden ist. (Die ältesten frühinterglazialen Abschnitte sind nicht erfaßt worden). Danach kann (mit Thomson) Wallensen dem letzten Interglazial zugeordnet und die erwähnte Waldfolge auch für die nordwestlichen Mittelgebirge als gültig angesehen werden. Von Fagus wurde kein einziges Pollenkorn nachgewiesen. 2. Die pollenanalytischen Befunde konnten durch die Untersuchung von Großresten, u. a. durch zahlreiche Funde von Knospenschuppen ergänzt und erweitert werden. Insgesamt wurden 80 Sippen, meist Arten, z. T. Gattungen oder Familien, bestimmt, wonach Wallensen als artenreiche Interglazialflora bezeichnet werden kann. Die Wasserflora war während der Hasel-Eichenmischwaldzeit am reichhaltigsten; für diese Zeit konnten auch die in Europa heute ausgestorbenen interglazialen Leitpflanzen Brasenia purpurea und Dulichium spathaceum nachgewiesen werden. Bemerkenswert ist auch der Nachweis der heute südosteuropäischen Tilia tomentosa. Ein merkwürdiger Fruchtrest (Steinkern?), der unter Nr. 79 beschrieben worden ist und wahrscheinlich von keiner mitteleuropäischen Art stammt, gehört sowohl der Hasel-Eichenmischwald- wie der Hainbuchenzeit an. 3. Reiche Funde von Hex, Hedera, Taxus und Osmunda bezeugen eine gewisse thermische Ozeanität des Gebiets während aller Zeiten. Während der Hasel-Eichenmischwaldzeit und der Hainbuchenzeit dürfte das Gebiet aber sommerwärmer gewesen sein als heute.

description: Spreading the word about India’s first lunar mission, Chandrayan-1, national newspapers definitely did their bit. Around mid-October 2008, there were large spaces devoted to the details of spacecraft, its launch vehicle PSLV-CII, and the scientists involved in this project. This study tries to focus (quantitatively and qualitatively) on the coverage of launching of Chandrayan-1. Times of India and The Hindu are the newspapers selected for the study with the aim to assess the role of print media in creating awareness regarding an important scientific event. Sample includes 60 newspaper issues (30 each) dating from October 20- November 20, 2008.The comparative qualitative approach would involve use of photographs, quotes of reliable sources (scientists) and other effective media used by the two newspapers.

description: The primary analysis of randomized screening trials for cancer typically adheres to the intention-to-screen principle, measuring cancer-specific mortality reductions between screening and control arms. These mortality reductions result from a combination of the screening regimen, screening technology and the effect of the early, screening-induced, treatment. This motivates addressing these different aspects separately. Here we are interested in the causal effect of early versus delayed treatments on cancer mortality among the screening-detectable subgroup, which under certain assumptions is estimable from conventional randomized screening trial using instrumental variable type methods. To define the causal effect of interest, we formulate a simplified structural multi-state model for screening trials, based on a hypothetical intervention trial where screening detected individuals would be randomized into early versus delayed treatments. The cancer-specific mortality reductions after screening detection are quantified by a cause-specific hazard ratio. For this, we propose two estimators, based on an estimating equation and a likelihood expression. The methods extend existing instrumental variable methods for time-to-event and competing risks outcomes to time-dependent intermediate variables. Using the multi-state model as the basis of a data generating mechanism, we investigate the performance of the new estimators through simulation studies. In addition, we illustrate the proposed method in the context of CT screening for lung cancer using the US National Lung Screening Trial (NLST) data.

description: Amarok, Tulugak und Ukalik sind kleine, ultra-oligotrophe Seen auf Baffin Island, kanadische Arktis, die im Frühholozän eine natürliche Schwermetallanreicherung aufweisen, welche mit der von rezenten, belasteten Sedimenten vergleichbar ist. Während der letzten Eiszeit waren diese Seen nicht von Gletschermassen bedeckt (Refugien), so dass die Seen und ihre Einzugsgebiete während der letzten 40 000 Jahre aktive Ökosysteme waren. Die paläoökologischen Bedingungen wechselten zwischen kalten Zeiten mit geringer Vegetationsbedeckung, geringer Bodenbildung, starker Erosion, allochthonen klastischen Sedimenten, geringer Produktivität und sauren pH-Werten und wärmeren Zeiten mit Zunahme von Vegetationsbedeckung und Bodenbildung, geringerer Erosion, autochthonen organischen Sedimenten, stärkerer Produktivität und höheren pH-Werten. Die Veränderungen des Paläo-pH werden vor allem durch hydrologische und biogeochemische Prozesse in den Seen selbst gesteuert, weniger durch die Basenbereitstellung aus den Einzugsgebieten. Eine effektive synsedimentäre Konzentration von Schwermetallen im organischen Anteil hat im Frühholozän dazu geführt, dass unter bestimmten hydrologischen und ökologischen Bedingungen natürlicherweise Konzentrationen von Schwermetallen auftreten, die z. T. weit über dem normalerweise anzutreffenden geogenen Hintergrund liegen.

description: In this paper, we employ a novel, network analysis based approach to gain new insights with respect to the changes in the structure of intra-European Union (EU) milk product trade between 2001 and 2012. Several network indices are computed to assess the relative importance of the countries from a number of perspectives. The results emphasise that the trade network has become denser, yet its overall centralisation slightly decreased during the period. While the impacts of the 2004 EU enlargement are clearly visible, the effects of the 2008 financial crisis are less evident. Integration of countries that joined the EU in 2004 or 2007 (the so-called New Member States, NMS) is only partial, and depends on the category of milk product considered. Although the number of NMS trade relations increased constantly between 2001 and 2012, the relative importance of most of them did not change. A significant exception is Poland, which became one of the most important exporting countries.

description: We put forward a general procedure to obtain an approximate free energy density functional for any hard-core lattice gas, regardless of the shape of the particles, the underlying lattice or the dimension of the system. The procedure is conceptually very simple and recovers effortlessly previous results for some particular systems. Also, the obtained density functionals belong to the class of fundamental measure functionals and, therefore, are always consistent through dimensional reduction. We discuss possible extensions of this method to account for attractive lattice models.

description: Theater reflects the social fabric of a society. It is not just a medium of entertainment; rather it's a vibrant tool for cultural conservation. Cultures that lack arts and its allied forms rapidly stagnate and finally get diminished. If language is the spirit of a particular community or culture, theater and performing arts is its heart. Theater has also emerged as an important platform for cultural amalgamation thus reducing the gaps between two different societies or nations. India, as a British colony, once had a large Pashtun population roughly equal to that of Afghanistan, mostly concentrated in the North-West Frontier Province and Baluchistan. In Rohilkhand and Western Uttar Pradesh, Pashtuns made large settlements subsequent to 14 th century and prior to the 20 th century. The Pashtuns, as the history betrays give neck and neck fighting to the imperialist East India Company in 1857 with never surrendering absolutely. Today the Pashtuns in India can be divided into those who speak Pashto and those who speak Urdu, the latter group being much larger. Now, Pashtuns in India hardly remain in few thousands due to negative population growth. Pashtuns in India are highly educated and had worked on top brass positions in both government as well as non-government sectors. His Excellency, Dr. Late Zakir Hussein, the Third President of Independent India was a Pashtun. He received his doctorate in economics from the University of Berlin in 1926.In India; Pashtuns had hold high positions in various ministries, defense forces, commercial sectors as well as media-entertainment sector. Pashtuns are one of the most cultured societies on this planet. Hospitality, bravery, honesty, compassion forms the bed-rock of Pashtun culture. Since the dawn of civilization, Pashtun society had loved music and dance, though theatre shows its presence in the days of Khan Abdul Ghaffar Khan (Frontier Gandhi) who was fighting for the Independence of India and Pashtun renaissance. Pashtun theatre basically focuses on historical themes or Pashtun Nationalism. Pashtun dances which are collectively called Attan not only signify entertainment but also communicate strong social and cultural messages. Thus, this Research Paper attempts to zero in on the theater and other performing arts and the message conveyed by them to entire world in general and Pashtun Society in particular. As Afghanistan is rapidly moving towards path of national reconstruction, Pashtun theater and other performing arts are playing an important role in inspiring the Afghans to bring their lost glory back.
Harmonic oscillator force between heavy quarks

description: A renormalization group procedure for effective particles is applied to quantum chromodynamics of one flavor of quarks with large mass m in order to calculate light-front Hamiltonians for heavy quarkonia, H_lambda, using perturbative expansion in the coupling constant alpha_lambda. lambda is the renormalization group parameter with the interpretation of an inverse of the spatial size of the color charge distribution in the effective quarks and gluons. The eigenvalue equation for H_lambda couples quark-anti-quark states with sectors of a larger number of constituents. The coupling to states with more than one effective gluon, and interactions in the quark-anti-quark-gluon sector, are removed at the price of introducing an ansatz for the gluon mass, mu^2. The simplified equation is used to evaluate a new Hamiltonian of order alpha_lambda that acts only in the effective quark-anti-quark sector and in the non-relativistic limit turns out to contain the Coulomb term with Breit-Fermi orrections and spin-independent harmonic oscillator term with frequency omega = [(4/3)(alpha_lambda/pi)]^1/2 lambda (lambda/m)^2 (pi/1152)^1/4. The latter originates from the hole excavated in the overlapping quark self-interaction gluon clouds by the exchange of effective gluons between the quarks. The new term is largely independent of the details of mu^2 and in principle can fit into the ball park of phenomenology. The first approximation can be improved by including more terms in H_lambda and solving the eigenvalue equations numerically.

description: Given its strong dependence of its economic results on natural factors, agriculture is characterised by high exposure to risk. This paper explores the relationship between the prevailing ‘model of agriculture’ in a country and methods of risk management (in particular, insurance schemes). The Czech Republic and Poland are post-socialist countries which are characterised by different models of agricultural development. While agriculture in the Czech Republic is oriented to industrial farming with large farms, Polish agriculture has a bipolar structure that includes both small, family-owned farms and large agricultural holdings. Various approaches to agricultural insurance schemes may arise from the contrasting models of agriculture, and substantial differences in both the demand and supply sides of the crop and livestock insurance markets indicate different policy approaches to the role of agriculture in the economies of the two countries. In both the Czech Republic and Poland, policy options for farm risk management should consider the balance between budget flexibility and the criterion of efficiency (from the perspective of insurers).

Such a potential supports the existence of localized stationary states and we show that using a radio frequency field allows to selectively address the atoms in these states. This method is used to measure the energy and momentum distribution of the atoms in the localized states. We also discuss possible extensions of this scheme to address and manipulate particles in single lattice sites.

description: A fundamental challenge in impact evaluations that rely on a quasi-experimental design is to define a control group that accurately reflects the counterfactual situation. Our aim is to evaluate empirically the performance of a range of approaches that are widely used in economic research. In particular, we compared three different types of matching algorithms (optimal, greedy and nonparametric). These techniques were applied in the evaluation of the impact of the MARENA programme (Manejo de Recursos Naturales en Cuencas Prioritarias), a natural resource management programme implemented in Honduras between 2004 and 2008. The key findings are: (a) optimal matching did not produce better-balanced matches than greedy matching; and (b) programme impact calculated from nonparametric matching regressions, such as kernel or local linear regressions, yielded more consistent outcomes. Our impact results are similar to those previously reported in the literature, and we can conclude that the MARENA programme had a significant, positive impact on beneficiaries.

subject: 22E46, 14D20

description: In this talk we discuss the relations between representations of algebraic groups and principal bundles on algebraic varieties, especially in characteristic $p$. We quickly review the notions of stable and semistable vector bundles and principal $G$-bundles, where $G$ is any semisimple group. We define the notion of a low height representation in characteristic $p$ and outline a proof of the theorem that a bundle induced from a semistable bundle by a low height representation is again semistable. We include applications of this result to the following questions in characteristic $p$: 1) Existence of the moduli spaces of semistable $G$-bundles on curves. 2) Rationality of the canonical parabolic for nonsemistable principal bundles on curves. 3) Luna's etale slice theorem. We outline an application of a recent result of Hashimoto to study the singularities of the moduli spaces in (1) above, as well as when these spaces specialize correctly from characteristic 0 to characteristic $p$. We also discuss the results of Laszlo-Beauville-Sorger and Kumar-Narasimhan on the Picard group of these spaces. This is combined with the work of Hara and Srinivas-Mehta to show that these moduli spaces are $F$-split for $p$ very large. We conclude by listing some open problems, in particular the problem of refining the bounds on the primes involved.

description: Following the detection of strong TeV gamma-ray flares from the BL Lac object 1ES 1959+650 with the Whipple 10 m Cherenkov telescope on May 16 and 17, 2002, we performed intensive Target of Opportunity (ToO) radio, optical, X-ray and TeV gamma-ray observations from May 18, 2002 to August 14, 2002. Observations with the X-ray telescope RXTE and the Whipple and HEGRA gamma-ray telescopes revealed several strong flares, enabling us to sensitively test the X-ray/gamma-ray flux correlation properties. Although the X-ray and gamma-ray fluxes seemed to be correlated in general, we found an ``orphan'' gamma-ray flare that was not accompanied by an X-ray flare. After describing in detail the radio (UMRAO, VLA), optical (Boltwood, Abastumani), X-ray (RXTE) and gamma-ray (Whipple, HEGRA) light curves and Spectral Energy Distributions (SEDs) we present initial modeling of the SED with a simple Synchrotron Self-Compton (SSC) model. With the addition of another TeV blazar with good broadband data, we consider the set of all TeV blazars to begin to look for a connection of the jet properties to the properties of the central accreting black hole thought to drive the jet. Remarkably, the temporal and spectral X-ray and gamma-ray emission characteristics of TeV blazars are very similar, even though the masses estimates of their central black holes differ by up to one order of magnitude.

description: Science communicators use various techniques for promoting an easier access to science. They generally use films, literature, poetry, drama and theater etc. to communicate the message to the target audience. Recently science fiction has also established itself through different media as an effective means of communicating science. Science Fiction films have so far played a pivotal role in inspiring millions regarding science as a subject of learning and understanding. This research paper attempts to study that how far science fiction films have been able to communicate pure science among the public. For this, the researcher intends to analyze the content of four popular science fiction films by using Content Analysis method so that it become clear that what proportion of pure science has been communicated. The following films have been selected by using systematic random sampling techniques: 1) Evolution 2) Jurassic Park-I 3) The Day after Tomorrow 4) Twenty Thousands Leagues under the Sea. The research study will explore the issues highlighted by these films and there relevance in the contemporary scientific scenario.

description: The Laser Interferometer Space Antenna (LISA) is a European Space Agency mission that aims to measure gravitational waves in the millihertz range. The three-spacecraft constellation forms a nearly-equilateral triangle, which experiences flexing along its orbit around the Sun. These time-varying and unequal armlengths require to process measurements with time-delay interferometry (TDI) to synthesize virtual equal-arm interferometers, and reduce the otherwise overwhelming laser frequency noise. Algorithms compatible with such TDI combinations have recently been proposed in order to suppress the phase fluctuations of the onboard ultra-stable oscillators (USO) used as reference clocks. In this paper, we propose a new method to cancel USO noise in TDI combinations. This method has comparable performance to existing algorithms, but is more general as it can be applied to most TDI combinations found in the literature. We compute analytical expressions for the residual clock noise before and after correction, accounting for the effect of time-varying beatnote frequencies, previously neglected. We present results of numerical simulations that are in agreement with our models, and show that clock noise can be suppressed below required levels. The suppression algorithm introduces a new modulation noise, for which we propose a partial mitigation. This modulation noise remains the limiting effect for clock-noise suppression, setting strict timing requirements on the sideband generation.

description: Feeding the world’s population in a sustainable manner is one of the key challenges facing the future of global agriculture. The recent removal of the milk quota regime in the European Union has prompted an expansionary phase in dairy farming, especially in Ireland. Achieving this expansion in a sustainable manner is crucial to the long-term survival and success of the Irish dairy sector. In this paper we examine the sustainability of Irish dairy farming, defining ‘sustainability’ as economically profitable, environmentally friendly and socially efficient. A typology of Irish dairy farms has been created using data on profitability, environmental efficiency and social integration derived from the Teagasc National Farm Survey. Economic, social and environmental performance indicators were determined and aggregated and then used in a multivariate analysis for the identification and classification of farm clusters. The purpose of this study to classify Irish dairy farms using performance indicators; thereby, assisting policy makers in identifying patterns in farm performance with a view to formulating more targeted policies. Two of the three clusters elicited from the analysis were similar in regards to their respective indicator scores. However, the remaining cluster was found to perform poorly in comparison. The results indicate a clear distinction between ‘good’ and ‘weak’ performers, and the positive relationship between the economic, environmental and social performance of Irish dairy farms is evident.

description: We study a quantum network extending in one-dimension (chain of square loops connected at one vertex) made up of quantum wires with Rashba spin-orbit coupling. We show that the Rashba effect may give rise to an electron localization phenomenon similar to the one induced by magnetic field. This localization effect can be attributed to the spin precession due to the Rashba effect. We present results both for the spectral properties of the infinite chain, and for linear transport through a finite-size chain connected to leads. Furthermore, we study the effect of disorder on the transport properties of this network.

description: In the summer of 2014, Russia imposed a food embargo on most agricultural products from countries that supported the anti-Russian sanctions. In this study we use vector autoregression and neural network modelling to assess the effect of the embargo on the bilateral trade relations between the European Union (EU) (using the example of Hungary as an EU Member State) and Russia. In particular, the changes in the dynamics of Hungary’s aggregate agricultural exports in response to the shock of the embargo, as well as to Russia’s imports of products banned under the embargo, are analysed. The work also looks at the effectiveness of the introduction of the embargo with the aim of implementing import substitution policies and supporting domestic producers. Our results show the ineffectiveness of the Russian import substitution policy and the negative effects on both Russian and Hungarian parties.

Streda-like formula in spin Hall effect

description: A generalized Streda formula is derived for the spin transport in spin-orbit coupled systems. As compared with the original Streda formula for charge transport, there is an extra contribution of the spin Hall conductance whenever the spin is not conserved. For recently studied systems with quantum spin Hall effect in which the z-component spin is conserved, this extra contribution vanishes and the quantized value of spin Hall conductivity can be reproduced in the present approach. However, as spin is not conserved in general, this extra contribution can not be neglected, and the quantization is not exact.

The Bianchi IX model in Loop Quantum Cosmology

description: The Bianchi IX model has been used often to investigate the structure close to singularities of general relativity. Its classical chaos is expected to have, via the BKL scenario, implications even for the approach to general inhomogeneous singularities. Thus, it is a popular model to test consequences of modifications to general relativity suggested by quantum theories of gravity. This paper presents a detailed proof that modifications coming from loop quantum gravity lead to a non-chaotic effective behavior. The way this is realized, independently of quantization ambiguities, suggests a new look at initial and final singularities.

description: In this paper, the results of an interview survey of farmers in Győr-Moson-Sopron, Fejér, Hajdú-Bihar, Jász-Nagykun-Szolnok, Pest and Zala (NUTS 3) counties of Hungary are used to demonstrate the major factors of climate change perception, such as the terms psychological climate, temporality and problem localisation. Adaptation strategies are also discussed. The interview results underline the subjectivity of temporality as well as the fact that the phenomenon of localisation and the narratives for place attachment differ when climate change is interpreted within the locality. Considering adaptation, it seems that Hungarian agriculture includes individuals who can be regarded as leaders or as people escaping ahead in terms of climatic adaptation, but the majority seems to be unable to follow them because they lack the necessary knowledge, technology or financial resources.

Numerical Evaluation of Fragility Curves for Earthquake-Liquefaction-Induced Settlements of an Embankment

description: The major cause of earthquake damage to an embankment is the liquefaction of the soil foundation that induces ground level deformations. It is well known that the liquefaction appears when the soil loses its shear strength due to the excess of pore water pressure. This phenomenon leads to several disastrous damages of the soil foundation. The aim of this paper is to assess numerically the effect of the liquefaction-induced settlement of the soil foundation on an embankment due to 76 real earthquakes extracted from the PEER database. For this purpose, a 2D finite element model of a dam founded on a layered soil/rock profile was considered. An elastoplastic multi-mechanism model was used to represent the soil behaviour. The crest settlement of the embankment was selected as the quantifiable damage variable of the study. Fragility functions were drawn to give the probability exceedance of some proposed damage levels as function of a seismic severity parameter. In addition, the anisotropy was tested by the change in the soil permeability and a comparison with the isotropy was held. According to the results, the crest settlement increases with the peak ground acceleration and the fragility functions showed that above 0.2g, the probability to have moderate damage in the anisotropic case reaches unity whereas it is lesser in the isotropic case. The embankment will not show serious damage for this same value of acceleration in the two cases.

A Survey of Analogs to Weak MgII Absorbers in the Present

description: We present the results of a survey of the analogs of weak MgII absorbers (rest frame equivalent width W(2796) < 0.3 A) at 0 < z < 0.3. Our sample consisted of 25 HST/STIS echelle quasar spectra (R = 45,000) which covered SiII 1260 and CII 1335 over this redshift range. Using those similar transitions as tracers of MgII facilitates a much larger survey, covering a redshift pathlength of g(z) = 5.3 for an equivalent width limit of MgII corresponding to W(2796) > 0.02 A, with 30% completeness for the weakest lines. We find the number of weak MgII absorber analogs with 0.02 < W(2796) < 0.3 to be dN/dz = 1.00 +/- 0.20 for 0 < z < 0.3. This value is consistent with cosmological evolution of the population. We consider the expected effect on observability of weak MgII absorbers of the decreasing intensity of the extragalactic background radiation eld from z~1 to z~0. Assuming that all the objects that produce absorption at z~1 are stable on a cosmological timescale, and that no new objects are created, we would expect dN/dz of 2-3 at z~0. About 30-50% of this z~0 population would be decendants of the parsec-scale structures that produce single-cloud, weak MgII absorbers at z~1. The other 50-70% would be lower density, kiloparsec-scale structures that produce CIV absorption, but not detectable low ionization absorption, at z~1. We conclude that at least one, and perhaps some fraction of both, of these populations has evolved away since z~1, in order to match the z~0 dN/dz measured in our survey. This would follow naturally for a population of transient structures whose generation is related to star-forming processes, whose rate has decreased since z~1.

description: The efficiency of energy transduction in a temporally asymmetric rocked ratchet is studied. Time asymmetry favours current in one direction and suppresses it in the opposite direction due to which large efficiency ~ 50% is readily obtained. The spatial asymmetry in the potential together with system inhomogeneity may help in further enhancing the efficiency. Fine tuning of system parameters considered leads to multiple current reversals even in the adiabatic regime.
