description: Direct laser Interference Patterning (DLIP) with ultrashort laser pulses (ULP) represents a precise and fast technique to produce tailored periodic sub-micrometer structures on various materials. In this work, an experimental and theoretical approach is presented to investigate the previously unexplored fundamental mechanisms for the formation of unprecedented laser-induced topographies on stainless steel following proper combinations of DLIP with ULP. DLIP is aimed to determine the initial conditions of the laser-matter interaction by defining an ablated region while double ULP are used to control the reorganisation of the self-assembled laser induced sub-micrometer sized structures by exploiting the interplay of different absorption and excitation levels coupled with the melt hydrodynamics induced by the first of the double pulses. A multiscale physical model is presented to correlate the interference period, polarization orientation and number of incident pulses with the induced morphologies. Special emphasis is given to electron excitation, relaxation processes and hydrodynamical effects that are crucial to the production of complex morphologies. Results are expected to derive new knowledge of laser-matter interaction in combined DLIP and ULP conditions and enable enhanced fabrication capabilities of complex hierarchical sub-micrometer sized structures for a variety of applications.

description: The main objective of the paper was to determine the diversity and factors deciding about the variation in milk production in selected EU macro-regions. Differentiation was determined using cluster analysis, which allowed for the creation of five homogeneous groups of regions. Based on the results of factor analysis factors having a decisive influence on the processes of economic adjustment of very large dairy farms were identified. Additionally, the European macro-regions that developed most after 2004 were mentioned, alongside with those that worsened their competitive position.
Transit Detectability of Ring Systems Around Extrasolar Giant Planets

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate whether rings around extrasolar planets could be detected from those planets' transit lightcurves. To this end we develop a basic theoretical framework for calculating and interpreting the lightcurves of ringed planet transits based on the existing framework used for stellar occultations, a technique which has been effective for discovering and probing ring systems in the solar system. We find that the detectability of large, Saturn-like ring systems is largest during ingress and egress, and that reasonable photometric precisions of $\sim 1-3 \times 10^{-4}$ with 15-minute time resolution should be sufficient to discover such ring systems. For some ring particle sizes, diffraction around individual particles leads to a detectable level of forward-scattering that can be used to measure modal ring particle diameters. An initial census of large ring systems can be carried out using high-precision follow-up observations of detected transits and by the upcoming NASA \emph{Kepler} mission. The distribution of ring systems as a function of stellar age and as a function of planetary semimajor axis will provide empirical evidence to help constrain how rings form and how long rings last.

description: E 'stato dimostrato che la quota nel mondo di manifatture da esortazione i di imprese situate negli Stati Uniti si sono mossi nella direzione opposta a quella quota di imprese americane multinazionali , compresi entrambi i loro domestici e le loro operazioni all'estero . La quota americano è caduto costantemente dal 1950 fino alla metà degli anni 1970 , ma la quota degli Stati Uniti imprese multinazionali non è diminuito affatto o addirittura aumentato ( Lipsey e Kravis , 1985) . Questo contrasto suggerisce che è importante distinguere tra i fattori che determinano la competitività degli Stati Uniti come un luogo di produzione e quelle che determinano la competitività delle imprese statunitensi . Alla luce di questa considerazione , l'autrice indaga It has been shown that the share in world manufactured exports of firms located in the U.S. moved in the opposite direction of the share of U.S. multinational firms, including both their domestic and their overseas operations. The U.S. share fell steadily from the 1950s through the mid-1970s, but the share of U.S. multinational firms did not decline at all or even increased (Lipsey and Kravis, 1985). This contrast suggests that it is important to distinguish between the factors that determine the competitiveness of the U.S. as a production location and those that determine the competitiveness of U.S. firms. In light of this consideration, the author investigates. JEL: F23

description: The most important tasks of Polish agriculture in 2014-2020 perspective will include maintaining food quality and safety, and orientation toward the part of the production of renewable energy, especially using biomass. Processing of biomass in anaerobic methane fermentation of agricultural biogas solves the problem of waste storage, reducing greenhouse gas emissions, especially high concentrations of methane, coming from the fermentation of slowly stored biomass. The economic aspect explains the popularity of biogas works; it is related to diversification of agricultural production through the introduction of a qualitatively new production of green energy from biogas, which significantly affects the profitability of agricultural production and will be an alternative for some companies, or large farms as a source of additional income and energy security. Energy generated in small biogas plants can fully protect the energy needs of a small farm releasing it from external sources and generating savings. For installations larger surplus may provide an additional source of farms’ income.

description: Alkali metal dimers attached to the surface of helium nanodroplets are found to be efficiently doubly ionized by electron transfer-mediated decay (ETMD) when photoionizing the helium droplets. This process is evidenced by detecting in coincidence two energetic ions created by Coulomb explosion and one low-kinetic energy electron. The kinetic energy spectra of ions and electrons are reproduced by simple model calculations based on diatomic potential energy curves, and are in agreement with ab initio calculations for the He-Na_2 and He-KRb systems. This work demonstrates that ETMD is an important decay channel in heterogeneous nanosystems exposed to ionizing radiation.

description: Binary random variables are the building blocks used to describe a large variety of systems, from magnetic spins to financial time series and neuron activity. In Statistical Physics the Kinetic Ising Model has been introduced to describe the dynamics of the magnetic moments of a spin lattice, while in time series analysis discrete autoregressive processes have been designed to capture the multivariate dependence structure across binary time series. In this article we provide a rigorous proof of the equivalence between the two models in the range of a unique and invertible map unambiguously linking one model parameters set to the other. Our result finds further justification acknowledging that both models provide maximum entropy distributions of binary time series with given means, auto-correlations, and lagged cross-correlations of order one. We further show that the equivalence between the two models permits to exploit the inference methods originally developed for one model in the inference of the other.

description: Regional diversification in the Polish agriculture is a result of climatic and social conditions, as well as historical developments. The aim of this paper is the assessment of the role that the CAP plays in the transformation of Polish agriculture is based on a comparative analysis of data on agriculture and the use of support by individual regions since the Polish EU accession until 2013. The results indicate the widening gaps in the development of agriculture in Polish regions. Regions with small farms receive less support for improving agricultural competitiveness. It is necessary to take account of these differences and design policy measures better targeted at individual needs of each of the regions. It seems that CAP does not shrink regional diversity of the Polish agriculture. However, it appears that it is not a key factor leading to an increase in this diversity, but an additional factor alongside with current conditions for conducting different types of agricultural activity.

description: A garden of Passiflora edulis var. flavicarpa was plantes 19 Aprill 994. The purpose of the planting was to compare two types of trellis systems: cross or "T" and back or fence. The cross shaped trellises were made up of metal pipes 1.5 m. high from the ground to top crossed by .9 m. pipes at a hèight of 1.2 m. Three wires ran parallel to each other from cross to cross, separated .3 m. from one another. The back trellis system used the same metal pipes 1.5 m high, without the cross. Two wires ran from pipe to pipe, one .9 m. and the other 1.2 m. from the ground. This type of trellis system is less expensive. The experiment of two treatments (the trellis systems) and three replications. Each treatment carried 45 plants, that is, 15 plants per replication per treatment. The vines were planted 3.7 m. within the row, and 3.7 m. between rows, using five plants per row. Results were analysed by LSD tests. Cross shaped trellises do promote a significantly higher production (290 kgs vs 226 kgs). The reason why so many local growers use the fence trellis system may have more to do with reducing expenses.

description: Bahiagrass (Paspalum notatum) is the predominant pasture grass in Florida and occupies over 1 million ha in the state. Fertilization with soluble Ν sources is usually performed in order to increase forage yield and quality. The objective of this study was to evaluate biosolids as an alternative slow release nitrogen source for bahiagrass. The effects of application of 7 rates of granular municipal biosolids, ranging from 0 to 17.6 Mg ha"1, were studied on field plots of an established bahiagrass pasture. Forage and soil samples (to 90 cm) were collected monthly for analysis of macronutrients and selected metals. Significant increases in forage yield, protein content and IVOMD were obtained with rates higher than 2.2 Mg biosolids ha"1. Over 60% of the Ν contained in the biosolids were recovered in the forage in the first year of application. Soil pH and conductivity were not affected by biosolids and NH4-N and N03 -N concentrations in soil samples were below 1 mg kg'1. Increases in plant or soil metal contents were not substantial to yield environmental concerns. This study has demonstrated that biosolids are a safe alternative source of nitrogen for pasture grasses grown in Florida.

description: The curvature potential arising from confining a particle initially in three-dimensional space onto a curved surface is normally derived in the hard constraint $q \to 0$ limit, with $q$ the degree of freedom normal to the surface. In this work the hard constraint is relaxed, and eigenvalues and wave functions are numerically determined for a particle confined to a thin layer in the neighborhood of a toroidal surface. The hard constraint and finite layer (or soft constraint) quantities are comparable, but both differ markedly from those of the corresponding two dimensional system, indicating that the curvature potential continues to influence the dynamics when the particle is confined to a finite layer. This effect is potentially of consequence to the modelling of curved nanostructures.

description: Debido a lo erosionado y a lo poco productivo de muchos suelos de ladera en América Central, se realizô este estudio para probar la efectividad de los abonos verdes como agente recuperador de suelos degradados. Para ello se utilizaron très leguminosas (Canavalia ensiformis, Mucuna pruriens y Dolichos lablad) sembrados en un suelo diferente cada uno. Las leguminosas crecieron por 85 dias, y luego se cortaron. Los tratamientos fueron incorporado, sin incorporar como mantillo verde y testigo (en barbecho). Despues de un periodo de 33 dias de descompOsiciôn de los materiales, estando estos sobre ο incorporados al suelo, se procediô a la sieinbra de frijol comun variedad Tio Canela 75. Antes y después del periodo de descomposiciôn se tomaron muestras de suelo a 10 y 20 cm de profundidad para la determination de las variables asociadas a la fertilidad del suelo. Durante el periodo de crecimiento del frijol se tomaron muestras de humedad del suelo a 10 y 20 cm de profundidad. Los resultados demostraron que el uso de abonos verdes en los très tipos de suelos no produjeron cambios signifïcativos en la fertilidad y capacidad de retention de humedad de los suelos a los 33 dias después de aplicados los tratamientos. Sin embargo, con el tratamiento de incorporation se registre) un aumento significativo en los rendimientos del frijol en los suelos menos degradados. Se determinô que una temporada de uso de abonos verdes no fue suficiente para mejorar el potencial de rendimiento del cultivo de frijol en el suelo sumamente degradado, el cual estaba compactado, con bajo contenido de materia orgânica y nitrôgeno total.

description: A class of chiral gauge theories is studied with accidentally-stable pseudo Nambu-Goldstone bosons playing the role of dark matter (DM). The gauge group contains a vector-like dark color factor that confines at energies larger than the electroweak scale, and a ${\rm U}(1)_D$ factor that remains weakly coupled and is spontaneously broken. All new scales are generated dynamically, including the DM mass, and the IR dynamics is fully calculable. We analyze minimal models of this kind with dark fermions transforming as non-trivial vector-like representations of the Standard Model (SM) gauge group. In realistic models, the DM candidate is a SM singlet and comes along with charged partners that can be discovered at high-energy colliders. The phenomenology of the lowest-lying new states is thus characterized by correlated predictions for astrophysical observations and laboratory experiments.

Inoltre, queste modalità possono cambiare nel tempo . Queste " nuove forme di investimenti stranieri " sono stati più evidenti nei settori del petrolio e dei metalli , ma anche nel settore manifatturiero , in particolare per i mercati dei paesi ospitanti e nelle industrie con tecnologie mature . Vi è, tuttavia , una notevole variazione nell'esperienza di diversi paesi e settori . In realtà , questi " nuove forme di investimenti diretti " sono né nuovi né nel più stretto senso investimento . Ma sono diventati più frequenti , e hanno , in una certa misura , sostituite forme più tradizionali di investimento Since the 1960’s and 1970’s there has been a growing tendency to add to traditional forms of control so that it can be shared to varying degrees and can be confined to specific areas. Moreover, these arrangements may change over time. These “new forms of foreign investment” have been most in evidence in the petroleum and metals industries, but also in manufacturing, particularly for host country markets and in industries with mature technologies. There is, however, considerable variation in the experience of different countries and sectors. In fact, these “new forms of direct investment” are neither new, nor in the strictest sense investment. But they have become more frequent, and they have, to some extent, replaced more traditional forms of investment. JEL: E22, F21

Questo consisteva nella rimozione delle commissioni fisse in UK transazioni in titoli , l'abolizione del sistema di capacità di singolo , e l'eliminazione delle barriere all'ingresso nei mercati mobiliari del Regno Unito . L'autore prende in considerazione cinque questioni prudenziali sollevate da questo evento : potenza monopolio e dominio straniero , di armonizzazione internazionale della vigilanza , di adeguatezza patrimoniale e di competenza gestionale , la gestione di ' cadere ' (uscita dal settore ) , e conflitti di interesse . Tre ulteriori fattori sono considerati in dettaglio ; l'approccio del regolatore di conflitti di interesse, la regolamentazione dei conglomerati finanziari , e le implicazioni del Testo Unico della Finanza . In October 1986 the London Stock Exchange underwent what was termed the Big Bang. This consisted of the removal of fixed commissions on UK securities transactions, the abolition of the single capacity system, and the removal of barriers to entry to UK securities markets. The author considers five prudential issues raised by this event: monopoly power and foreign dominance, international supervisory harmonisation, capital adequacy and managerial competence, the management of 'fall out' (exit from the industry), and conflicts of interest. Three further factors are considered in detail; the regulator's approach to conflicts of interest, the regulation of financial conglomerates, and the implications of the Financial Services Act.

description: We introduce iterative methods named TriCG and TriMR for solving symmetric quasi-definite systems based on the orthogonal tridiagonalization process proposed by Saunders, Simon and Yip in 1988. TriCG and TriMR are tantamount to preconditioned Block-CG and Block-MINRES with two right-hand sides in which the two approximate solutions are summed at each iteration, but require less storage and work per iteration. We evaluate the performance of TriCG and TriMR on linear systems generated from the SuiteSparse Matrix Collection and from discretized and stablized Stokes equations. We compare TriCG and TriMR with SYMMLQ and MINRES, the recommended Krylov methods for symmetric and indefinite systems. In all our experiments, TriCG and TriMR terminate earlier than SYMMLQ and MINRES on a residual-based stopping condition with an improvement of up to 50% in terms of number of iterations. They also terminate more reliably than Block-CG and Block-MINRES. Experiments in quadruple and octuple precision suggest that loss of orthogonality in the basis vectors is significantly less pronounced in TriCG and TriMR than in Block-CG and Block-MINRES.

Dynamic modeling of human jaw and laryngeal biomechanics
Creators: name: Stavness, Ian Kent
Publisher: name: University of British Columbia
Year: 2011

description: Computational modeling is an important tool for studying the structure and function of human anatomy in biomedicine. In this thesis, a dynamic, anatomically accurate model of the human mandibular and laryngeal structures is presented. The complexities of the infra-mandibular anatomy are discussed along with previous approaches to jaw modeling and a detailed description of dynamic modeling techniques. Forward dynamic simulations, created with the model's comprehensive user-interface, are reported that show consistency with previously published jaw modeling literature. Laryngeal motion during swallowing was simulated and shows plausible upward displacement consistent with published recordings. Simulation of unilateral chewing was also performed with the model to study mastication mechanics. A novel open-source modeling platform, ArtiSynth, is described in the context of its use and extension in the construction and simulation of the biomechanical jaw and laryngeal model.

description: We analyse two-dimensional maps and radial profiles of EW(H$α$), EW(H$δ_A$), and D$_n$(4000) of low-redshift galaxies using integral field spectroscopy from the MaNGA survey. Out of $\approx1400$ nearly face-on late-type galaxies with a redshift $z<0.05$, we identify 121 "turnover" galaxies that each have a central upturn in EW(H$α$), EW(H$δ_A$) and/or a central drop in D$_n$(4000), indicative of ongoing/recent star formation. The turnover features are found mostly in galaxies with a stellar mass above $\sim$10$^{10}$ M$_{\odot}$ and NUV-$r$ colour less than $\approx5$. The majority of the turnover galaxies are barred, with a bar fraction of 89$\pm$3\%. Furthermore, for barred galaxies the radius of the central turnover region is found to tightly correlate with one third of the bar length. Comparing the observed and the inward extrapolated star formation rate surface density, we estimate that the central SFR have been enhanced by an order of magnitude. Conversely, only half of the barred galaxies in our sample have a central turnover feature, implying that the presence of a bar is not sufficient to lead to a central SF enhancement. We further examined the SF enhancement in paired galaxies, as well as the local environment, finding no relation. This implies that environment is not a driving factor for central SF enhancement in our sample. Our results reinforce both previous findings and theoretical expectation that galactic bars play a crucial role in the secular evolution of galaxies by driving gas inflow and enhancing the star formation and bulge growth in the center.

description: We study theoretically the influence of ferromagnetic metals on a superconducting film in the clean limit. Using a self-consistent solution of the Bogoliubov--de Gennes equation for a ferromagnet-superconductor-ferromagnet double junction we calculate the pair potential and conductance spectra as a function of the superconducting layer thickness $d$ for different strengths of ferromagnets and interface transparencies. We find that the pair potential and the critical temperature are weakly perturbed by the exchange interaction and do not drop to zero for any finite $d$. On the other hand, for thin superconducting films charge transport is spin polarized and exhibits a significant dependence on the ferromagnetic strength and magnetization alignment.

description: The share of industrial waste heat infeed into district heating systems networks increased over the past couple of years. Industrial waste heat recovery increases systems-energy efficiency factor on the one hand and reduces carbon dioxide and mono-nitrogen oxide emissions through the substitution of fossil fuels for heating boilers on the other hand. Therefore, it is a value adding process, both for industries and environment authorities. Nevertheless, waste heat from exhaust gas in natural gas compressor stations has been utilised directly in only few projects. Highly fluctuating operation hours of gas compressors and therefore unpredictable waste heat streams are the results of variable gas flow in natural gas pipelines. Such conditions make a feasible waste heat recovery operation very difficult. In spite of such an instable operation environment the outcome is analysed in different scenarios in order to proof the feasibility of waste heat recovery unit applications in compressor stations. Load scenarios for the compressor station in Weitendorf/ Austria at the TAG Trans Austrian Gas pipeline are compared to each other. Different waste heat recovery technologies such as the steam operated Clausius rankine cycle and simple heat exchanger are taken into consideration. Finally, calculations of utilisation scenarios with different feed-in tariffs for electricity generation and heat supply are discussed. A risk assessment and a sensitive analysis, in which especially operation and maintenance costs are considered, contributes to a reduction the project uncertainties. Results underline the benefits of direct waste heat utilisation in district heating systems compared to electric power generation for certain feed-in situations.

description: A field experiment was conducted to determine the economic feasibility of intercrop- ping bean (Phaseolus vulgaris L.) and plantain (Musa acuminata χ M· balbisiana AAB) at Corozal, Puerto Rico in 1995-1996. Treatment variables consisted of two bean cultivars (Arroyo Loro and 9443-1) and two frequencies of intercroppings (once and twice). The results indicated that two intercroppings of 9443-1 outyielded significantly (P<0.05) one intercropping of Arroyo Loro but did not outyield one intercropping of 9443-1. However, there was no significant yield difference between the two intercroppings of Arroyo Loro and the two intercroppings of 9443-1. Plantain yield, in terms of the number of fruits, was not significantly affected by intercropping. The highest net income of the intercropping treatment was obtained from the two intercroppings of 9443-1 ($7,706/ha). This represents an additional income of $ 4,922/ha over that of plantain monoculture. The high production cost of bean incurred from two intercroppings resulted in less-than- expected net income as compared to that of one intercropping within one growing cycle of plantain.

description: La realtà sociale che i modelli cercano di interpretare i cambiamenti nel tempo . Tutti i modelli sono storicamente condizionati , ma alcuni sono più di altri . In questo studio , l'autore presenta i risultati di diverse stime econometriche che , sulla base di alcune ipotesi teoriche , mettono in evidenza alcune regolarità empiriche . Queste regolarità sono di natura probabilistica e dipendono dati strutturali specifici, " fette" di storia sono relativamente stabili , ma che cambiano nel corso del tempo , talvolta anche in brevi intervalli di tempo . Mentre gli economisti neoclassico ragionare in termini di interdipendenza , un concetto statico , il ragionamento svolto in questo documento sia in termini di interazione , una dinamica The social reality which models seek to interpret changes over time. All models are historically conditioned, but some are more so than others. In one way or another all theoretical models un unemployment take account of this, however, they do so implicitly. In this study, the author presents the results of various econometric estimates which, on the basis of certain theoretical hypotheses, bring out some empirical regularities. These regularities are of a probabilistic nature and depend on the structural data which in specific “slices” of history are relatively stable, but which change in the course of time, occasionally even in short time spans. While neoclassical economists reason in terms of interdependence, a static concept, the reasoning put forward in this paper is in terms of interaction, a dynamic one. JEL: E24, J64

description: Field trials were carried out in organic soils naturally deficient in phosphorus (P) fertility to determine the effects of different fertility regimens of this nutrient and common lambsquarters initial removal times on lettuce marketable yields. Phosphorus was either banded (125 Kg P/ha) or broadcast (250 Kg P/ha) prior to lettuce planting. A single lambsquarters population density of 4 plants per 5.4 m2 was allowed to interfere with "South Bay" lettuce within each Ρ regime. Lambsquarters were removed at 2, 4, 6 or 8 weeks after lettuce emergence, along with the weed-free control. When lettuce was grown under weed-free conditions, banded Ρ increased lettuce marketable yields by 27% compared to Ρ broadcast. With banded P, no significant differences were observed between the 2 week removal and the weed-free control. On the other hand, differences were accounted between the weed-free control and the 2 week removal (aproximately 24% reduction). No differences on lettuce marketable yields occurred after 4 and 6 weeks for broadcast and banded P, respectively. Maximum yield reductions of about 47 and 51 % for banded and broadcast Ρ were measured. These findings suggest that banding Ρ in lettuce stands increase the time of lambsquarters interference necessary to reduce lettuce yields.

description: La crisi del debito è stata innescata nel 1982 da una combinazione di fattori esterni avversi e poveri politiche economiche e finanziarie da parte dei paesi debitori . Inoltre , dopo il secondo "shock"del petrolio , la stagnazione nella zona industriale ha causato un brusco rallentamento del commercio mondiale , così come ha ulteriormente deteriorando le esportazioni per i paesi in via di sviluppo . Il presente lavoro analizza il problema del debito per i paesi in via di sviluppo , le sue cause , le politiche attuate finora e le possibili soluzioni . La strategia per combattere il problema tra il 1982 e il 1985 è dettagliato e il piano Baker è considerato. L'autore esamina poi gli sviluppi più recenti e schemi innovativi per facilitare la soluzione del problema del debito . Infine , le stime sono fornite dell'impatto di alcuni sforzi di riduzione del debito sul sistema bancario e sui paesi debitori The debt crisis was triggered in 1982 by a combination of adverse external factors and poor economic and financial policies on the part of debtor countries. Furthermore, after the second oil "shock", stagnation in the industrial area caused a sharp slowdown in world trade, thus further deteriorating exports for developing countries. The present work analyses the debt problem for developing countries, its causes, the policies enacted thus far and possible solutions. The strategy to combat the problem between 1982 and 1985 is detailed and the Baker Plan is considered. The author then looks at more recent developments and innovative schemes to facilitate the solution of the debt problem. Finally, estimates are provided of the impact of some debt relief efforts on the banking system and on debtor countries. JEL: F34
