description: (abbreviated) We use a semi-numerical approach to study the secular behavior of a system composed of a central star and two massive planets in eccentric co-planar orbits. We show that the secular dynamics of this system can be described using only two parameters, the ratios of the semimajor axes and the planetary masses. The main dynamical features of the system are presented in geometrical pictures that allows us to investigate a large domain of the secular phase space of this three-body problem without time-expensive numerical integrations of the equations of motion, and without any restriction on the magnitude of the planetary eccentricities. We show that three different regimes of secular motion with respect to the secular angle $Δ\varpi$ are possible: they are circulation, oscillation (around 0 and $180^\circ$), and high eccentricity libration in a nonlinear secular resonance. The first two regimes are a continuous extension of the classical linear secular perturbation theory; the last is a new feature, hitherto unknown, in the secular dynamics of the three-body problem.

description: Cycads are listed in the International Union for Conservation of Nature Red list of threatened plants. Cycad species Encephalartos whitelockii (P.J.H. Hurter) exist in a forest gorge along River Mpanga in western Uganda where human population is rapidly rising and land use practices are dynamically changing. This study examined the population structure of E.whitelockii specifically focusing on assessing the population structure and regeneration capacity of E.whitelockii and the relative abundance and diversity of indigenous tree species associated with E.whitelockii. Stratified random sampling was used to collect ecological data in 33 transects and 165 sample plots covering a total area of 16.5 ha. The results show that the population of E.whitlockii consisted of more juveniles than adults. The E.whitelockii was most abundant on the lower hill slopes and grew closely to Combrettum molle and Acacia hockii. In order to conserve the species it is recommended that the entire habitat of E.whitelockii should be gazetted into a protected area and on-farm conservation, propagation and ecotourism should be encouraged among the frontline communities. Further research should be conducted on the phenology and reproductive biology of E.whitelockii. The local communities should develop bye laws on land use practices aimed at protecting Cycads from seed poachers.
Optical spectral weight distribution in d-wave superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The distribution in frequency of optical spectral weight remaining under the real part of the optical conductivity in the superconducting state of a d-wave superconductor depends on impurity concentration, on the strength of the impurity potential as well as on temperature and there is some residual absorption even at T = 0. In BCS theory the important weight is confined to the microwave region if the scattering is sufficiently weak. In an Eliashberg formulation substantial additional weight is to be found in the incoherent, boson assisted background which falls in the infrared and is not significantly depleted by the formation of the condensate, although it is shifted as a result of the opening of a superconducting gap.

description: The reniform nematode population in the rhizosphere of Bengal bean (Stizolobium aterrimum Pipêr &: Tracy) was significantly lower than that of Cowpea ( Vigna unguiculata (L.) Walp.) three months after planting both crops in soil of similar initial nematode population density. Moreover, examination of the development of the nematode on Bengal bean roots revealed that only a small percentage of the reniform nematodes which enter the root develop to become egg-laying females. The data suggest that Bengal bean has resistance to reniform nematode. Several studies have shown that the reniform nematode Rotylenchulus reniformis Linford and Oliveira, 1940, is one of the most abundant plant parasitic nematodes in the soils of the Caribbean ( 1 , 2 , 4 , 6). Brathwaite (1) found that although reniform nematode was widespread in Montserrat, the nematode did not occur in the rhizosphere of Bengal bean (Stizolobium aterrimum Piper 8c Tracy). The objective of the study was to define the host parasite relationship, if any, between reniform nematode and Bengal bean.

description: The pi omega rho coupling constant is calculated in a relativistic hadronic framework incorporating nucleons and Delta(1232) isobars. Medium modifications are included. The vertex is analyzed in context of the omega to pi e+e- and rho to pi e+e- Dalitz decays in nuclear matter. A sizeable increase of the widths for these decays is found for invariant mass of dileptons in the range 0.2-0.5 GeV. This increase may help, among other medium effects, to explain the problem of the low-mass dilepton enhancement seen in relativistic heavy-ion collisions.

description: In a R-parity violating (RPV) model of neutrino mass with three bilinear couplings $μ_i$ and three trilinear couplings $λ'_{i33}$, where $i$ is the lepton index, we find six generic scenarios each with a distinctive pattern of the trilinear couplings consistent with the oscillation data. These patterns may be reflected in direct RPV decays of the lighter top squark or in the RPV decays of the lightest superparticle, assumed to be the lightest neutralino. Typical signal sizes at the Tevatron RUN II and the LHC have been estimated and the results turn out to be encouraging.

description: One hundred tomato cultivars were direct seeded, and treated with one postemergent application of Lcxone at 28 days following the first irrigation. Applications of 0.56, 1.12, 1.68 and 2.24 kg ai/ha (0.50, 1.00, 1.50 and 2.00 lbs ai/ac) of metribuzin was made directly over the plants. Ten days after the application, the observed results were as follows: six cultivars were tolerant to all treatments, while 33 were tolerant up to the 1.68 kg/ha level only. Sixty of the cultivars demonstrated tolerance up to the 1.12 kg/ha level. One cultivar was susceptible to all rates tested. Seven weed species were encountered, and their response to the postemergent herbicide was: complete kill of Digitaria sanguinalis, Trianthema portulacastrum, Amaranthus dubids, Phyllanthus niruri, Kailstromea maxima and Portulaca oleracea at all rates. Echinochloa colonum was tolerant at 0.56 and 1.12 kg ai/ha level; and susceptible at the 1.68 and 2.24 kg ai/ha rates.

description: We present iterative Monte Carlo algorithm for which the temperature variable is attracted by a critical point. The algorithm combines techniques of single histogram reweighting and linear filtering. The 2d Ising model of ferromagnet is studied numerically as an illustration. In that case, the iterations uncovered stationary regime with invariant probability distribution function of temperature which is peaked nearly the pseudocritical temperature of specific heat. The sequence of generated temperatures is analyzed in terms of stochastic autoregressive model. The error of histogram reweighting can be better understood within the suggested model. The presented model yields a simple relation, connecting variance of pseudocritical temperature and parameter of linear filtering.

description: Solution-processed networks of semiconducting, single-walled carbon nanotubes (SWCNTs) have attracted considerable attention as materials for next-generation electronic devices and circuits. However, the impact of the SWCNT network composition on charge transport on a microscopic level remains an open and complex question. Here, we use charge-modulated absorption and photoluminescence spectroscopy to probe exclusively the mobile charge carriers in monochiral (6,5) and mixed SWCNT network field-effect transistors. Ground state bleaching and charge-induced trion absorption features, as well as exciton quenching are observed depending on applied voltage and modulation frequency. Through correlation of the modulated mobile carrier density and the optical response of the nanotubes, we find that charge transport in mixed SWCNT networks depends strongly on the diameter and thus bandgap of the individual species. Mobile charges are preferentially transported by small bandgap SWCNTs especially at low gate voltages, whereas large bandgap species only start to participate at higher carrier concentrations. Our results demonstrate the excellent suitability of modulation spectroscopy to investigate charge transport in nanotube network transistors and highlight the importance of SWCNT network composition for their performance.

XMM-Newton and the Pleiades -- I: Bright coronal sources and the X-ray emission from intermediate-type stars

description: We perform X-ray spectral and timing analyses of solar-like (spectral types F5--K8) and intermediate-type (B4--F4) Pleiads observed in a 40-ks XMM-Newton EPIC exposure. All 8 solar-like members have ``quasi-steady'' \lx $\ga 10^{29}$ erg/s and 4 exhibit flares. Using a hydrodynamic modelling technique we derive loop half-lengths ${\cal L} \la 0.5 R_{\star}$ for the two strongest flares, on HII 1032 and HII 1100. HII 1100's lightcurve suggests a total occultation of the flaring loop. Eclipse by a substellar companion in a close orbit is possible but would seem a highly fortuitous event; absorption by a fast-moving cloud of cool material requires \nh at least two orders of magnitude greater than any solar or stellar prominence. An occultation may have been mimicked by the coincidence of two flares, though the first, its decay time shorter than its rise time and suggestive of ${\cal L} \sim 0.02 R_{\star}$, would be unusual. Spectral modelling of the quasi-steady emission shows a rising trend in coronal temperature from F and slowly-rotating G stars through K stars to fast-rotating G stars, and a preference for low coronal metallicity: features consistent with those of nearby solar-like stars, although none of the three stars showing ``saturated'' emission bears the significant component at 2 keV seen in the saturated coronae of AB Dor and 47 Cas. Of 5 intermediate-type stars, 2 are undetected (\lx$ < 4 \times 10^{27}$ erg/s) and 3 show X-ray emission with a spectrum and \lx consistent with origin from an active solar-like companion.

description: We study the phase structures of charge neutral quark matter under the beta-equilibrium for a wide range of the quark-quark coupling strength within a four-Fermion model. A comprehensive and unified picture for the phase transitions from weak to strong coupling is presented. We first develop a technique to deal with the gap equation and neutrality constraints without recourse to numerical derivatives, and show that the off-diagonal color densities automatically vanish with the standard assumption for the diquark condensates. The following are shown by the numerical analyses: (i) The thermally-robustest pairing phase is the two-flavor pairing (2SC) in any coupling case, while the second one for relatively low density is the up-quark pairing (uSC) phase or the color-flavor locked (CFL) phase depending on the coupling strength and the value of strange quark mass. (ii) If the diquark coupling strength is large enough, the phase diagram is much simplified and is free from the instability problems associated with imaginary Meissner masses in the gapless phases. (iii) The interplay between the chiral and diquark dynamics may bring a non-trivial first order transition even in the pairing phases at high density. We confirm (i) also by using the Ginzburg-Landau analysis expanding the pair susceptibilities up to quartic order in the strange quark mass. We obtain the analytic expression for the doubly critical density where the two lines for the second order phase transitions merge, and below which the down-quark pairing (dSC) phase is taken over by the uSC phase. Also we study how the phase transitions from fully gapped states to partially ungapped states are smeared at finite temperature by introducing the order parameters for these transitions.

description: Linearisation of the Navier-Stokes equations about the mean of a turbulent flow forms the foundation of popular models for energy amplification and coherent structures, including resolvent analysis. While the Navier-Stokes equations can be equivalently written using many different sets of dependent variables, we show that the properties of the linear operator obtained via linearisation about the mean depend on the variables in which the equations are written prior to linearisation. For example, we show that using primitive and conservative variables leads to differences in the singular values and modes of the resolvent operator for turbulent jets, and that the differences become more severe as variable-density effects increase. This lack of uniqueness of mean-flow-based linear analysis provides new opportunities for optimizing models by specific choice of variables while also highlighting the importance of carefully accounting for the nonlinear terms that act as a forcing on the resolvent operator.

description: We find asymptotically anti de Sitter solutions in N=8 supergravity which have negative total energy. This is possible since the boundary conditions required for the positive energy theorem are stronger than those required for finite mass (and allowed by string theory). But stability of the anti de Sitter vacuum is still ensured by the positivity of a modified energy, which includes an extra surface term. Some of the negative energy solutions describe classical evolution of nonsingular initial data to naked singularities. Since there is an open set of such solutions, cosmic censorship is violated generically in supergravity. Using the dual field theory description, we argue that these naked singularities will be resolved in the full string theory.

description: UPROFIG, union of farmers of yam network in Guadeloupe, was created in 2001 in the purpose to develop yam culture and thus to help agriculture of Guadeloupe to leave the logic of monocultures and to promote other diversified systems, producing first for the domestic market. The first stage consisted in setting up a device of production of sound planting material, in the aim at giving to farmers the choice of a lot of varieties adjusted to various soils and climates. Indeed, sanitary quality of tubers using as seedlings, with that of soil, are essential for a sound production. Today, our action is widening to capitalization of techniques which are alternatives to intensives ones and to artificialization of environment (use of pesticides, weedkillers, agricultural water and manure). This is why, beyond the general technical councils carried out, UPROFIG works on some practices, like mulch of field in the driest places, use of organic matter... Feasibility studies (financial, technical, etc.) with the producers, installation of on-farm experiments, capitalization 416 of existing knowledge and their application in farmer's field are as much of action carried out by UPROFIG, in partnership with research and other organizations for agricultural development, so that the production of yams in Guadeloupe can satisfy consumers and farmers.

description: It is demonstrated that new JLAB proton polarization data, which are in a rather strong disagreement with the proton electric form factor data in the space-like region obtained by Rosenbluth technique, are consistent with all known form factor properties, including also the QCD asymptotics, but they require an existence of a zero (i.e. a diffraction minimum) around $t$=15 GeV$^2$ of the proton electric form factor. The latter leads to a change of our knowledge about the charge distribution inside of the proton.

description: Selectivity estimation aims at estimating the number of database objects that satisfy a selection criterion. Answering this problem accurately and efficiently is essential to many applications, such as density estimation, outlier detection, query optimization, and data integration. The estimation problem is especially challenging for large-scale high-dimensional data due to the curse of dimensionality, the large variance of selectivity across different queries, and the need to make the estimator consistent (i.e., the selectivity is non-decreasing in the threshold). We propose a new deep learning-based model that learns a query-dependent piecewise linear function as selectivity estimator, which is flexible to fit the selectivity curve of any distance function and query object, while guaranteeing that the output is non-decreasing in the threshold. To improve the accuracy for large datasets, we propose to partition the dataset into multiple disjoint subsets and build a local model on each of them. We perform experiments on real datasets and show that the proposed model consistently outperforms state-of-the-art models in accuracy in an efficient way and is useful for real applications.

description: The correlation functions of the spin-1/2 XXZ spin chain in the ground state are expressed in the form of the multiple integrals. For -1< Delta <1, they were obtained by Jimbo and Miwa in 1996. Especially the next nearest-neighbour correlation functions are given as certain three-dimensional integrals. We shall show these integrals can be reduced to one-dimensional ones and thereby evaluate the values of the next nearest-neighbor correlation functions. We have also found that the remaining one-dimensinal integrals can be evaluated analytically, when nu = arccos(Delta)/pi is a rational number.

description: Hot pepper production in the CARICOM countries occur using seeds of openpollinated landraces from the region, with West Indies Red being the dominant cultivar planted followed by Scotch Bonnet. The Caribbean Agricultural Research and Development Institute (CARDI) developed West Indies Red in an effort to diversify the region's crop commodity portfolio and because of the interest in Caribbean hot peppers on the export markets (USA, Canada, UK). CARDI's hot pepper improvement program has progressed by collecting germplasm of the region, conserving and evaluating these and developing new improved open pollinated landrace cultivars. It has been noted that among the constraints (irrigation, fertilization, pest management, post harvest handling) to field production, virus diseases are probably the most significant. Attempts have therefore been made in cooperation with the Asian Vegetable Research Development Center (AVRDC) to precisely identify the viral disease profile occurring in production plots. The predominant viruses identified in 2004 were CMV and PVY. It is planned that new germplasm resistant to these viruses will be introduced from Taiwan (AVRDC) and screened in Barbados. Accessions found to be resistant in the Caribbean will be used to develop new cultivars via hybridization and selection of outstanding progeny.

description: Sedimentkerne aus dem von der Mulde durchflossenen Bitterfelder Muldestausee (Sachsen-Anhalt, Deutschland) sind ein ausgezeichnetes Beispiel für das hohe Potential von Flussstauseen, die bei Hochwasserereignissen eintretenden Veränderungen in der Schwebstoff- und Sedimentqualität objektiv abzuschätzen. Voraussetzung hierfür bilden gesicherte Daten zur zeitlichen Zuordnung der in den Sedimentkernen auftretenden Ereignis- bzw. Hochwasserlagen. Konnektierungen mit Durchflussdaten der Mulde seit 1975 geben die Möglichkeit, die in den Sedimentkernen auftretenden Ereignislagen konkreten Hochwässern der Mulde mit einem Durchfluss größer 300 m³/s zu zuordnen. Darüberhinaus bilden markante Zeitmarken: (a) das durch den Tschernobyl-Fallout hervorgerufene (137)Cs-Aktivitätsmaximum, (b) der seit der politischen Wende (1989/90) einsetzende Rückgang in der organischen Belastung und (c) der mit der Schließung des Berg- und Hüttenwesens Industrie im Muldeeinzugsgebiet ebenfalls einhergehende Trend abnehmender Element- und Isotopenkonzentrationen. Am Beispiel eines im September 2002 aus dem Friedersdorfer Becken des Bitterfelder Muldestausees gewonnenen Kurzkernes werden die Ergebnisse der auf verschiedene Methoden gestützten zeitlichen Konnektierung von Sedimentlagen zu konkreten Hochwasserereignissen vorgestellt. Die im Sedimentkern auftretende jüngste und im Ergebnis des August-2002-Hochwassers abgesetzte Ereignislage erweist sich hinsichtlich Mächtigkeit des Sedimentauftrages und geochemischer Eigenschaften als eine besonders markante Hochwasserzeitmarke.

description: Strategies for the generation of periodic discrete structures with identical two-point correlation are developed. Starting from a pair of root structures, which are not related by translation, phase inversion or axis reflections, child structures of arbitrary resolution (i.e., pixel or voxel numbers) and number of phases (i.e., material phases/species) can be generated by means of trivial embedding based phase extension, application of kernels and/or phase coalescence, such that the generated structures inherit the two-point-correlation equivalence. Proofs of the inheritance property are provided by means of the Discrete Fourier Transform theory. A Python 3 implementation of the results is offered by the authors through the Github repository https://github.com/DataAnalyticsEngineering/EQ2PC in order to make the provided results reproducible and useful for all interested readers. Examples for the generation of structures are demonstrated, together with applications in the homogenization theory of periodic media.

Radiocarbon dates for upper Eem and Würminterstadial samples

description: Es wird eine Übersicht gegeben von C14-Daten von Eem-interglazialen und Würm-interstadialen Proben von Loopstedt (Schleswig-Holstein), Amersfoort (Niederlande), Lebenstedt, Roggendorf, Karrestobel, Geesthacht, Upton Warren (England), Fladbury (England) und von einer Serie von Holzkohle-Proben aus den Lößgebieten. Sogar die jüngsten Eem-Proben zeigten keine signifikante Aktivität (Alter mehr als 53 000 Jahre). Die Daten stellen das Interstadial Würm II/III (fossiler Boden von Paudorf) auf rund 26 000 Jahre vor heute. Die Daten für das Interstadial I/II sind noch teilweise unzuverlässig, weil Verunreinigung mit rezentem Material (Wurzeln, Humus) für diese alten Proben relativ viel für die totale Aktivität beiträgt. Obwohl die Periode zwischen 33 000 und 42 000 Jahren (vor heute) ziemlich kalt war, ist es nicht unmöglich, daß es sich hier um das Interstadial WI/II handelt. Ein wärmeres Interstadial endete vor ungefähr 48 000 Jahren. Die Daten stimmen mit Emilianis Paläotemperaturkurve (und Milankovitchs Zeitskala) überein.

description: The Doctorate Support Group (DSG) Webinars, which began in early 2015, is one of the flagship programs introduced under the DSG initiatives in order to promote the postgraduate resources portal to its 52,000 members on Facebook. The DSG Webinars utilizes numerous technological applications to stream the webinars to its viewers. This paper elaborates on the applications utilized to organize the DSG Webinars and their potential in promoting lifelong learning. Different technological applications were used throughout the entire process, from initiating the webinar registration, to the streaming of the livewebinar, the discussion of the lessons, and the hosting of the webinar replay on the DSG resource page. The hosted webinar replays offer a continuous learning experience for DSG members and other visitors. It is intended that this paper could serve as a reference for similar initiatives by other support groups and spur greater interest for further research on the potential of using technological applications for lifelong learning,.

description: We present a model for nebular emission in star forming galaxies, which takes into account the effects of dust reprocessing. The nebular emissions have been computed with CLOUDY and then included into GRASIL, our spectrophotometric code specifically developed for dusty galaxies. The interface between nebular emission and population synthesis is based on a set of pre-computed HII region emission models covering a wide range of physical quantities. Concerning the extinction properties of normal star forming galaxies, we are able to interpret the observed lack of correlation between the attenuation measured at Halpha and in the UV band as a consequence of age selective extinction. We also find that, for these galaxies with modest SFR, the ratio FIR/UV provides the best constraints on the UV attenuation. Our model also allows to deal with different SFR estimators in a consistent way, from the UV to radio wavelengths, and to discuss the uncertainties arising from the different physical conditions encountered in star forming galaxies. We provide our best estimates of SFR/luminosity calibrations, together with their expected range of variation. It results that SFR derived through Halpha, even when corrected for extinction using the Balmer decrement, is affected by important uncertainties due to age selective extinction. Another remarkable result is that SFR from UV luminosity corrected by means of the ratio FIR/UV has a small uncertainty. Finally, our model provides a calibration of SFR from radio luminosity; we are also able to reproduce the observed FIR/radio ratio.

Subnivale Kleinoserbildung. - Eine Beobachtung zur Schuttumlagerungsdynamik im Wimbachgries (Berchtesgadener Alpen)
Creators: name: Schneider, Thomas
Publisher: name: Geozon Science Media
Year: 1994

description: Die Umlagerungsdynamik auf den großen Dolomit-Schuttflächen des Wimbachgries (Berchtesgadener Alpen) ist in erster Linie an starke sommerliche Gewitterregen gebunden, durch welche die Aufnahmefähigkeit des mächtigen Schuttkörpers überschritten und somit oberflächlichen Abgang von Wasser und Lockermaterial, meist in Form von Muren, bewirkt wird. Durch Ausaperung werden jedoch regelmäßig gegen Ende des Winterhalbjahres Formen freigelegt, welche auch auf Schuttumlagerungsvorgänge in bzw. unter der Schneedecke hinweisen. Aufgrund deutlicher Parallelen zu den entsprechenden Großformen werden diese als subnivale Kleinoser angesprochen. Sie scheinen bevorzugt dort vorzukommen, wo aufgrund der topographischen Situation größere Schmelzwassermengen bei noch gefrorenem Untergrund anfallen; für ihre Bildung ist offensichtlich die relativ homogene und feinkörnige Natur des "Gries" Materials förderlich.

description: Los rendimientos potenciales de raices frescas de yuca pueden superar las 70 t/ha (CIAT 1979), en el pais se obtienen 8 t/ha (SEA 2003). Esta diferencia se debe a la siembra de variedades inadecuadas y el uso de prâcticas agronômicas déficientes. Una prâctica que contribuye al aprovechamiento del terreno y a eficientizar la aplicaciôn de tecnologias, es usar marcos de siembra adecuados. Esta investigaciôn tuvo por objetivo determinar el mejor marco para las variedades evaluadas y su efecto sobre el rendimiento de raices frescas comerciales. Se realizô en Esperanza, Provincia Valverde en el periodo octubre 2001-julio 2002. Se utilizô un diseno de parcelas divididas con el factor "variedad" en parcela principal y el factor "marco de plantaciôn" en subparcelas. Se utilizô cinco variedades y cuatro distancias de siembra. Cada tratamiento se replicô cuatro veces. Los rendimientos de raices fueron diferentes estadisticamente (p=0.05) para ambos factores. No hubo diferencias para la interacciôn distancias por variedades. Un anâlisis de regresiôn entre las distancias mostrô que a mayor distancia los rendimientos disminuyen. Los rendimientos mejores se obtuvieron al sembrar a 1.0m entre hileras por 0.40m entre plantas con 29.65 t/ha, y los mâs bajos a lxlm con 23.9 t/ha. La variedad "Americanita" produjo mayor cantidad de raices (34.22 t/ha), la variedad "Taverita" presentô los rendimientos mâs bajos 21.5 t/ha, seguida de "Bilin" 23.6 t/ha y "Negrita" 24.1 t/ha.

description: This is a survey about the Skorokhod embedding problem. It presents all known solutions together with their properties and some applications. Some of the solutions are just described, while others are studied in detail and their proofs are presented. A certain unification of proofs, based on one-dimensional potential theory, is made. Some new facts which appeared in a natural way when different solutions were cross-examined, are reported. Azéma and Yor's and Root's solutions are studied extensively. A possible use of the latter is suggested together with a conjecture.
