Hydrogeological and Hydrochemical Investigations in West Nymph Creek Thermal Area, Yellowstone National Park, USA
Creators: name: Brimer, Baas
Publisher: name: Geologisches Institut
Year: 2005

description: Fast changing geothermal features characterize the Yellowstone National Park, USA. Highresolution aerial images were taken to map the hydrothermal study area. The combination of a digital camera and a low flying (< 100 m) helium balloon was a cost and time effective method to get a status quo of the feature’s form and size. The resulting aerial overview has a resolution of 2.5 cm and is presented in a multilayer digital atlas, providing a basis for further surveying. Ground survey included mapping and on-site hydrochemistry of 18 major hydrothermal features. Arsenic concentrations are known to be elevated in Yellowstone (1.7 ± 2 mg/L) - therefore, beside trace element analysis with ICP-AES, three techniques for As speciation were applied: HG-AAS, HPLC-ICP-MS, and on-site SPE with GF-AAS. Surprisingly low total As concentrations made an evaluation of the different methods difficult. Grouping the water samples revealed two water types: steam heated waters (type I) and waters with a deep thermal origin (type II). Thus, a known hydrogeological model (White et al. 1988) is checked for its applicability to the study area.

description: The young active star AB Dor (K1 IV-V) has been observed 16 times in the last three years with the XMM-Newton and Chandra observatories, totalling 650 ks of high-resolution X-ray spectra. The XMM/RGS observations with the highest and lowest average emission levels have been selected to study the coronal properties of AB Dor in two different activity levels. We compare the results based on the XMM data with those obtained from a higher resolution Chandra/HETG spectrum, using the same line-based analysis technique. We have reconstructed the plasma Emission Measure Distribution vs. temperature (EMD) in the range log T(K) ~ 6.1-7.6, and we have determined the coronal abundances of AB Dor, obtaining consistent results between the two instruments.The overall shape of the EMD is also consistent with the one previously inferred from EUVE data. The EMD shows a steep increase up to the peak at log T (K) ~ 6.9 and a substantial amount of plasma in the range log T (K) ~ 6.9-7.3. The coronal abundances show a clear trend of increasing depletion with respect to solar photospheric values, for elements with increasing First Ionization Potential (FIP), down to the Fe value ([Fe/H]=-0.57), followed by a more gradual recovery of the photospheric values for elements with higher FIP. He-like triplets and Fe XXI and Fe XXII lines ratios indicate electron densities log ne~10.8 cm^-3 at log T(K) ~ 6.3 and log ne ~ 12.5 at log T(K) ~ 7, implying plasma pressures steeply increasing with temperature. These results are interpreted in the framework of a corona composed of different families of magnetic loop structures, shorter than the stellar radius and in isobaric conditions, having pressures increasing with the maximum plasma temperature, and which occupy a small fraction (f ~ 10^-4 - 10^-6) of the stellar surface.

description: This study revisits the problem of the tragedy of the commons. Extracting agents participate in an evolutionary game in a complex social network and are subject to social pressure if they do not comply with the social norms. Social pressure depends on the dynamics of the resource, the network and the population of compliers. We analyze the influence the network structure has on the agents’ behavior and determine the economic value of the intangible good - social pressure. For a socially optimal management of the resource, an initially high share of compliers is necessary but is not sufficient. The analysis shows the extent to which the remaining level of the resource, the share of compliers and the size, density and local cohesiveness of the network contribute to overcoming the tragedy of the commons. The study suggests that the origin of the problem – shortsighted behavior - is also the starting point for a solution in the form of a one-time payment. A numerical analysis of a social network comprising 7500 agents and a realistic topological structure is performed using empirical data from the western La Mancha aquifer in Spain.

The bipolar bivalve Oxytoma (Palmoxytoma) cygnipes (Young & Bird, 1822) in the Upper Pliensbachian of Germany
Creators: name: Arp, Gernot
name: Seppelt, Stephan
Publisher: name: Springer-Verlag
Year: 2011

description: The morphologically conspicuous bivalve Oxytoma (Palmoxytoma) cygnipes (Young & Bird, 1822), known for its palaeogeographically bipolar distribution, from a limestone bed in the boundary “Belemniten–Schichten”/Amaltheenton formation, Lower Jurassic, in N Germany is described. The occurrence of this palaeoceanographically significant bivalve points to an influx of cool seawater from the Arctic to the North-German Basin at the base of the Upper Pliensbachian, just before the deposition of the Amaltheenton formation. A review of previously reported occurrences on the NW European Shelf indicates two distinct stratigraphic intervals of occurrence of this taxon: the Rhaetian–Hettangian boundary and the Upper Pliensbachian. Whereas the former interval of occurrence may be related to short-term cooling in the course of the end-Triassic extinction event, the latter is interpreted as reflecting the influx of a cool water current to the eastern part of the NW European Shelf, which continued southwards parallel to the coast of the Bohemian–Vindelician High.

description: For the large-scale linear discrete ill-posed problem $\min\|Ax-b\|$ or $Ax=b$ with $b$ contaminated by white noise, the Golub-Kahan bidiagonalization based LSQR method and its mathematically equivalent CGLS, the Conjugate Gradient (CG) method applied to $A^TAx=A^Tb$, are most commonly used. They have intrinsic regularizing effects, where the iteration number $k$ plays the role of regularization parameter. The long-standing fundamental question is: {\em Can LSQR and CGLS find 2-norm filtering best possible regularized solutions}? The author has given definitive answers to this question for severely and moderately ill-posed problems when the singular values of $A$ are simple. This paper extends the results to the multiple singular value case, and studies the approximation accuracy of Krylov subspaces, the quality of low rank approximations generated by Golub-Kahan bidiagonalization and the convergence properties of Ritz values. For the two kinds of problems, we prove that LSQR finds 2-norm filtering best possible regularized solutions at semi-convergence. Particularly, we consider some important and untouched issues on best, near best and general rank $k$ approximations to $A$ for the ill-posed problems with the singular values $σ_k=\mathcal{O}(k^{-α})$ with $α>0$, and the relationships between them and their nonzero singular values. Numerical experiments confirm our theory. The results on general rank $k$ approximations and the properties of their nonzero singular values apply to several Krylov solvers, including LSQR, CGME, MINRES, MR-II, GMRES and RRGMRES.

description: This paper analyzes transaction costs and spatial market integration of vegetable and fruit markets between major surplus producing zones and the Addis Ababa retail market taking onions, potatoes, and tomatoes from vegetables and root crops and bananas from fruits. Monthly retail price data from the Central Statistical Agency (CSA) from October 2008 to August 2015 was considered for the research. All retail price series from Addis Ababa and 21 zonal retail markets were transformed into natural logarithms in order to mitigate the fluctuation of individual series and to ease interpretation of the coefficients. The presence of long run relationship between two groups of markets is examined using a test for cointegration based on maximum likelihood approach developed by Johansen and Jesulus (1990). The dynamics of short-run price responses are explored using the vector error correction model (VECM). The result indicated that there is strong support for the presence of long run relationship between the surplus producing zonal vegetables and fruit markets and the Addis Ababa market. Although these markets responded positively for the long-run cointegrating relationship, the speed of price adjustment was found to the modest. A shock in Addis Ababa retail market took, on average, between 3 to 7 months to be fully absorbed in the surplus producing zonal markets. To increase the efficiency of vegetable and fruit markets, there is therefore a need to focus on reducing transaction costs related to transport, improving market information flow, removal of any sort of entry barriers, and introducing enhanced processing and storage technologies to extend shelf life and ensure producers to obtain a reasonable share of retail prices.

The code is now under public consultation which is why we decided to include a commented version of the code in the fourth issue of our SEF magazine, Fitopatología (Article published in Spanish). We remarked that some aspects may need to be considered further.

description: News diversity in the media has for a long time been a foundational and uncontested basis for ensuring that the communicative needs of individuals and society at large are met. Today, people increasingly rely on online content and recommender systems to consume information challenging the traditional concept of news diversity. In addition, the very concept of diversity, which differs between disciplines, will need to be re-evaluated requiring a interdisciplinary investigation, which requires a new level of mutual cooperation between computer scientists, social scientists, and legal scholars. Based on the outcome of a multidisciplinary workshop, we have the following recommendations, directed at researchers, funders, legislators, regulators, and the media industry: 1. Do more research on news recommenders and diversity. 2. Create a safe harbor for academic research with industry data. 3. Optimize the role of public values in news recommenders. 4. Create a meaningful governance framework. 5. Fund a joint lab to spearhead the needed interdisciplinary research, boost practical innovation, develop. reference solutions, and transfer insights into practice.

Strings and the stable cohomology of mapping class groups

description: Twenty years ago, Mumford initiated the systematic study of the cohomology ring of moduli spaces of Riemann surfaces. Around the same time, Harer proved that the homology of the mapping class groups of oriented surfaces is independent of the genus in low degrees, increasing with the genus. The (co)homology of mapping class groups thus stabelizes. At least rationally, the mapping class groups have the same (co)homology as the corresponding moduli spaces. This prompted Mumford to conjecture that the stable rational cohomology of moduli spaces is generated by certain tautological classes that he defines. Much of the recent interest in this subject is motivated by mathematical physics and, in particular, by string theory. The study of the category of strings led to the discovery of an infinite loop space, the cohomology of which is the stable cohomology of the mapping class groups. We explain here a homotopy theoretic approach to Mumford's conjecture based on this fact. As byproducts infinite families of torsion classes in the stable cohomology are detected, and the divisibility of the tautological classes is determined. An analysis of the category of strings in a background space leads to the formulization of a parametrized version of Mumford's conjecture. The paper is chiefly a summary of the author's work and her collaboration with Ib Madsen. Earlier this year Madsen and Weiss announced a solution of Mumford's conjecture. We touch on some of the consequences and the ideas behind this most exciting new developement.
title: Investigation of chiral silicon compounds for the determination of enantiomeric purity
Creators: name: Collicott, Roland
Publisher: name: The Open University
Year: 2002

description: Over the past two decades, chiral synthesis and separation have grown in importance, particularly in pharmaceuticals, where gross differences in pharmacological behaviour can occur between the enantiomers of a compound. The most tragic example is that of the racemic sedative, thalidomide. Widely used by pregnant women in the 1960's, it was the cause of deformity in many of their children. Under certain circumstances, only the S-(-)-enantiomer produces the teratogenic effect. The search for specific information on the effects of different enantiomers and increasing attempts to prepare enantiomerically enriched compounds has led to a large demand for enantioselective analytical methods. The two most widely employed techniques are NMR spectroscopy and chromatography. My research at the Open University focused on reagents based on silicon which could be used for derivatisation with the facility of the ubiquitous trimethylsilyl (TMS) reagents. I have investigated chiral chiorosilanes, in racemic form, to derivatise nucleophilic analytes. Because of the symmetry properties of some of the chiral silicon reagents prepared, the stereochemistry of the products is not dependent on the mechanism of reaction between an analyte and the reagent. The reagents were assessed by derivatising three chiral alcohols, which were used as model analytes: (1R, 2S, 5R)-menthol, 2-octanol and 1-phenylethanol. Chloromethylphenylsilane produced derivatives that were well resolved by GC, but was considered a poor choice of reagent on the grounds of its instability to racemisation and the instability of the diastereoisomeric products. 1 -Phenylethylchlorodimethylsilane gave derivatives that were well distinguished by NMR, while only partial separation by HPLC was obtained from the 2-octanol and 1-phenylethanol derivatives. No GC separations were achieved from this reagent. Two reagents possessing pseudo-C 2 symmetry, bis(1-phenylethyl)chloromethylsilane and 1 -chloro-1-methyl-2,5-diphenylsilacyclopentane were also unsuccessful in GC analysis, but the latter provided some promise for NMR analysis, with the derivatives of menthol being particularly well resolved.

description: Using Global Entrepreneurship Monitor (GEM) approach, the study analyzes the characteristics and determinants of entrepreneurship in Ethiopia. Primary data are collected through the Adult Population Survey (APS) and analyzed using Probit model. To overcome the hetroscedasticity problem, which is prevalent in cross-section studies, robust standard errors were employed. The findings of the study reveal that about 53% of the adults in Ethiopia are potential entrepreneurs. The perceived opportunity rate in Ethiopia (65%) is above the average for factor-driven economies (63%); while the perceived capabilities rate (69%) is below the average for factor driven economies (71%). Ethiopia’s rate of entrepreneurial intention (22%), early-stage entrepreneurial activity rate (12.2%), and established business activity rate (8.3%) are below the average for both factor-driven economies and Sub-Saharan African countries. The econometric analysis indicates that demographic variables such as age, level of education, societal attitude towards entrepreneurship, and social networks (knowing someone in business) are significant in influencing potential entrepreneurship and entrepreneurial intentions in Ethiopia. In early-stage entrepreneurial activity (TEA),"Fear of failure" is found to have a negative and statistically significant effect. On the other hand, the probability of engaging in TEA significantly differs between those living in urban and rural areas. Furthermore, the results provide basic data to develop national entrepreneurship strategy, consistent with the MSE development strategy and other macro and sectoral level strategies. Thus, the low rate of TEA and established business in Ethiopia can be improved by expanding the quantity and quality of support services. Moreover, there is also a need to develop region-specific entrepreneurial development plan to reduce region to region or urban-rural differences.

description: BACKGROUND:Automated volumetry software (AVS) has recently become widely available to neuroradiologists. MRI volumetry with AVS may support the diagnosis of dementias by identifying regional atrophy. Moreover, automatic classifiers using machine learning techniques have recently emerged as promising approaches to assist diagnosis. However, the performance of both AVS and automatic classifiers has been evaluated mostly in the artificial setting of research datasets.OBJECTIVE:Our aim was to evaluate the performance of two AVS and an automatic classifier in the clinical routine condition of a memory clinic.METHODS:We studied 239 patients with cognitive troubles from a single memory center cohort. Using clinical routine T1-weighted MRI, we evaluated the classification performance of: 1) univariate volumetry using two AVS (volBrain and Neuroreader$^{TM}$); 2) Support Vector Machine (SVM) automatic classifier, using either the AVS volumes (SVM-AVS), or whole gray matter (SVM-WGM); 3) reading by two neuroradiologists. The performance measure was the balanced diagnostic accuracy. The reference standard was consensus diagnosis by three neurologists using clinical, biological (cerebrospinal fluid) and imaging data and following international criteria.RESULTS:Univariate AVS volumetry provided only moderate accuracies (46% to 71% with hippocampal volume). The accuracy improved when using SVM-AVS classifier (52% to 85%), becoming close to that of SVM-WGM (52 to 90%). Visual classification by neuroradiologists ranged between SVM-AVS and SVM-WGM.CONCLUSION:In the routine practice of a memory clinic, the use of volumetric measures provided by AVS yields only moderate accuracy. Automatic classifiers can improve accuracy and could be a useful tool to assist diagnosis.
Carpathian Basin and the development of the Hungarian landscape theory until 1948
Creators: name: Hajdú, Zoltán
Publisher: name: RKK, Pécs
Year: 2004

description: The emphasis between theoretical, global and regional geography, proportion from research to publication has changed several times during the history of Hungarian geography. Certain scholars of Hungarian geography (geo-philosophers, and some theorists) were explicitly attached to theoretical issues of geographic science, yet the majority of geographers advantaged the concrete territorial descriptions and analysis. The regional approach appeared in the Hungarian geography much earlier than the demand on clarification of the theoretic issues of landscape. The first attempt to divide the country into macro landscapes was carried out in the first half of the 1500's. From this time on the geographic science formulated a demand to analyse the internal structure of the country within the frameworks of public administration or in the framework of some other way delimited geographic macro-regions. The administrative space enjoyed for centuries a favoured role, yet the demand for analyses based on the macro regional delimitation was always represented too. On general level the issues of landscape have already been present in Hungarian geographic science (the formulation of concepts, categories, border marking theories etc.), but Hungarian geographic science concerning the territorial research of Hungary has achieved the greatest results mostly in the fields of analytical landscape research, and evaluation ...

description: Scattering-type scanning near-field microscopy (s-SNOM) at terahertz (THz) frequencies could become a highly valuable tool for studying a variety of phenomena of both fundamental and applied interest, including mobile carrier excitations or phase transitions in 2D materials or exotic conductors. Applications, however, are strongly challenged by the limited signal to noise ratio. One major reason is that standard atomic force microscope (AFM) tips, which have made s-SNOM a highly practical and rapidly emerging tool, provide weak scattering efficiencies at THz frequencies. Here we report a combined experimental and theoretical study of commercial and custom-made AFM tips of different apex diameter and length, in order to understand signal formation in THz s-SNOM and to provide insights for tip optimization. Contrary to common beliefs, we find that AFM tips with large (micrometer-scale) apex diameter can enhance s-SNOM signals by more than one order of magnitude, while still offering a spatial resolution of about 100 nm at a wavelength of 119 micron. On the other hand, exploiting the increase of s-SNOM signals with tip length, we succeeded in sub-15 nm resolved THz imaging employing a tungsten tip with 6 nm apex radius. We explain our findings and provide novel insights into s-SNOM via rigorous numerical modeling of the near-field scattering process. Our findings will be of critical importance for pushing THz nanoscopy to its ultimate limits regarding sensitivity and spatial resolution.

description: A Multi-Phase Transport Model (AMPT) has been extensively used to understand the physics behind the experimental observation. Like other models, the outcome of the AMPT model depends on the initial parameters. Therefore, one needs to choose suitable initial parameters before using the model. Lund string fragmentation function has been used to create quark-antiquarks pairs in the AMPT model. The Lund string fragmentation parameters determine the yields and transverse momentum ($p_{T}$) spectra of particles produced in nucleus-nucleus collisions. The values of Lund string fragmentation parameters were determined by fitting the charged particle yield and $p_{T}$ spectra measured in the experiment. In this paper, we have shown the yield of strange quarks carrying hadrons, e.g. $ϕ$ mesons, are more sensitive to Lund string fragmentation parameters compared to non-strange pions. Using $ϕ$ meson spectra measured at RHIC, we have obtained new sets of Lund parameters for Au+Au collisions at $\sqrt{s_{\mathrm {NN}}}$ = 11.5, 39, and 200 GeV. We have found that using the same set of parameters, we can explain $ϕ$-meson yield at $\sqrt{s_{\mathrm {NN}}}$ = 39 and 200 GeV, however, we need a different set of parameters for $\sqrt{s_{\mathrm {NN}}}$ = 11.5 GeV. This suggests that at low energy, $\sqrt{s_{\mathrm {NN}}}$ = 11.5 GeV, the underlying mechanism for particle production is different compared to top RHIC energies. We have also predicted invariant yield of $π$ and $ϕ$ mesons as a function of $p_{T}$ in U+U collisions at $\sqrt{s_{\mathrm {NN}}}$ = 196 GeV to be measured by STAR experiment.

description: We introduce and investigate the class of central potentials $$V_{\text{CIC}}(g^{2},μ^{2},\ell,R;r)=-\frac{g^{2}}{R^{2}} (\frac{r}{R})^{4\ell} {[ 1+(\frac{1}{2\ell+1}) (\frac{r}{R})^{2\ell+1}]^{2}-1+μ^{2}}^{-2}$$, which possess, in the context of nonrelativistic quantum mechanics, a number of $\ell$-wave bound states given by the ($\ell$-independent !) formula $$N_{\ell}^{\text{(CIC)}}(g^{2},μ^{2}) ={{\frac{1}π\sqrt{g^{2}+μ^{2}-1} (\sqrt{μ^{2}-1})^{-1} \arctan(\sqrt{μ^{2}-1})}}$$. Here $g$ and $μ$ are two arbitrary real parameters, $\ell$ is the angular momentum quantum number, and the double braces denote of course the integer part. An extension of this class features potentials that possess the same number of $\ell$-wave bound states and behave as $(a/r)^{2}$ both at the origin ($r\to 0^{+}$) and at infinity ($r\to \infty$), where $a$ is an additional free parameter.
Unsteady thermal convection in the North-East German Basin

Publisher: name: WIAS, Berlin
Year: 2002

description: We describe a Voronoi box based finite volume method for the numerical simulation of thermal convection in sedimental basins. The method shows a temperature maximum principle and consistent velocity approximation. We present results of simulation runs in vertical slices of the North-East German basin. These indicate that the system is far from a stationary state, it shows quasi-periodic, and possibly chaotic behaviour. The chaos hypothesis is formulated based on the analysis of the Nusselt number time series obtaind from simulation runs.

description: Puerto Rico has been successfully exporting mangoes to the European market for the past three years. In 1986, 1407 tonnes were exported. Major producers/exporters are: Fruits Int'l Inc.; Huertos del Caribe 1nc. and ISPRAC Inc.; with 200, 320 and 69 hectares respectively; each producer marketing their fruits independently. Extending the harvest period from late April to early September could be important, since several mango varieties are available. Management and production technologies vary in each particular case. The Mango industry is characterized by high investment, high level technology and high yields of excellent quality. At present the mango produced in Puerto Rico can enter European markets without restrictions except for Spain. However, they are not permitted to enter the mainland United States markets until an acceptable treatment for fruit fly control is validated under local conditions. During 1986 a shipment of irradiated mangoes from Puerto Rico was permitted to enter the United States at Miami, Florida. Consumer acceptance was monitored. American consumers reacted positively to the irradiated mangoes. The economic feasibility of mango irradiation has yet to be determined.
Dynamical decoupling of spin ensembles with strong anisotropic interactions

description: Ensembles of dopants have widespread applications in quantum technology. The miniaturization of corresponding devices is however hampered by dipolar interactions that reduce the coherence at increased dopant density. We theoretically and experimentally investigate this limitation. We find that dynamical decoupling can alleviate, but not fully eliminate, the decoherence in crystals with strong anisotropic spin-spin interactions. Our findings can be generalized to all quantum systems with anisotropic g-factor used for quantum sensing, microwave-to-optical conversion, and quantum memory.
description: Second version of the manuscript contains additional measurements, in which dynamical decoupling in the absence of strong spin-spin interactions is demonstrated

description: Effects of 3 plant container types and 3 spacing treatments on plant growth and container temperatures were determined in St. Croix, U.S. V.I. These effects were compared with plant physiological response to supraoptimal root-zone temperatures in controlled environment studies. White rigid plastic plant containers or polyethylene containers placed inside large rigid plastic containers reduced the temperature in containers as compared to single black rigid plastic containers. Dracaena marginata 'Tricolor' root and shoot dry weights were greatest in white containers. Ixora chinensis 'Haui' height was greatest in white containers but dry weights were not affected by container type. A close pot spacing, also reduced the heat load, but the effect on maximum temperatures was minima1 from September to March. Such treatments did not affect 'Carrizo' citrange and 'Barbados Dwarf' papaya growth in containers. 'Grand Naine' banana root weight was significantly greater for plants in close spaced pots, compared to other spacing treatments.

Stochastic flow simulation in 3D porous media
Creators: name: Kolyukhin, Dmitry
name: Sabelfeld, Karl
Publisher: name: FID GEO
Year: 2005

description: Stochastic models and Monte Carlo algorithms for simulation of flow through porous media beyond the small hydraulic conductivity fluctuation assumptions are developed. The hydraulic conductivity is modelled as an isotropic random field with a lognormal distribution and prescribed correlation or spectral functions. It is sampled by a Monte Carlo method based on a randomized spectral representation. The Darcy and continuity equations with the random hydraulic conductivity are solved numerically, using the successive over relaxation method in order to extract statistical characteristics of the flow. Hybrid averaging is used: we combine spatial and ensemble avergaing to get efficient numerical procedure. We provide some conceptual and numerical comparison of various stochastic simulation techniques, and focus on the prediction of applicability of the randomized spectral models derived under the assumption of small hydraulic conductivity fluctuations.

Mid-IR observations of Galactic HII regions: constraining ionizing spectra of massive stars and the nature of the observed excitation sequences

description: Extensive photoionization model grids for single star HII regions using a variety of recent state-of-the-art stellar atmosphere models have been computed with the main aim of constraining/testing their predicted ionizing spectra against recent ISO mid-IR observations of Galactic HII regions, which probe the ionizing spectra between ~ 24 and 41 eV thanks to Ne, Ar, and S fine structure lines. Particular care has been paid to examining in detail the dependences of the nebular properties on the numerous nebular parameters (mean ionization parameter U, abundances, dust etc.) which are generally unconstrained for the objects considered here. Finally we have examined which parameters are chiefly responsible for the observed mid-IR excitation sequences. The galactic gradient of metallicity changing the shape of the stellar emission is found to be one of the drivers for the excitation sequence of Galactic HII regions, the actual contribution of this effect being finally atmosphere model dependent. We find that the dispersion of Teff between different HII regions due to statistical sampling of the IMF plus additional scatter in the ionization parameter are probably the dominant driver for the observed excitation scatter.
