title: A Computational study of clades and drug adaptation to remdesivir in SARS-CoV-2
Creators: name: Ueda, Naoki
Publisher: name: University of Kent
Year: 2022

description: The first patient of Coronavirus disease 2019 (COVID-19) was detected in December 2019. This infectious disease is caused by a virus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and infecting people globally. Many researchers have been investigating to elucidate the characteristics of this virus from many aspects since the beginning of the outbreak. However, there is still limited information about this virus. In this thesis, we focused on the differences between clades and drug adaptations in SARS-CoV-2. The second chapter focused on the differences between clades in SARS-CoV-2 by applying the method of differentially conserved positions (DCPs). DCPs can identify the differences between two groups of proteins by only amino acid sequences. We have used nomenclatures introduced by two organizations, GISAID and Nextstrain, to classify into clades. We identified DCPs between clades in SARS-CoV-2, which may reflect the differences of the phenotypes between clades. The third chapter focused on drug adaptation to remdesivir in SARS-CoV-2 in vitro. The collaborator in Frankfurt cultured two strains of the virus until it adapted to remdesivir, and genomic sequencing was performed by Public Health England. By comparing the genomic data between the resistant virus and the control virus, we identified a number of mutations that may be considered as the adaptation factor to remdesivir. We also assessed the effect that may occur on the structure of the proteins by mutations. The findings in this thesis provided information of DCPs between clades and information about the mutation that may cause an effect to the adaptation to remdesivir for future study of polymerase targeting drugs for SARS-CoV-2.

description: We applied the recently developed Generalized Langevin Equation (GLE) approach for dielectric response of liquids and glasses to link the vibrational density of states (VDOS) to the dielectric response of a model orientational glass (OG). The dielectric functions calculated based on the GLE, with VDOS obtained in experiments and simulations as inputs, are compared with experimental data for the paradigmatic case of 2-adamantanone at various temperatures. The memory function is related to the integral of the VDOS times a spectral coupling function $γ(ω_p)$, which tells the degree of dynamical coupling between molecular degrees of freedom at different eigenfrequencies. With respect to previous empirical fittings, the GLE-based fitting reveals a broader temperature range over which the secondary relaxation is active. Furthermore, the theoretical analysis provides a clear evidence of secondary relaxation being localized within the THz ($0.5-1$ THz) range of eigenfrequencies, and thus not too far from the low-energy modes involved in $α$-relaxation. In the same THz region, the same material displays a crowding of low-energy optical modes that may be related to the secondary relaxation.
Higher Dimensional Dust Cosmological Implications of a Decay Law for $Λ$ Term : Expressions for Some Observable Quantities

description: In this paper we have considered the multidimensional cosmological implications of a decay law for $Λ$ term that is proportional to $β\frac{\ddot {a}}{a}$, where $β$ is a constant and $a$ is the scale factor of RW-space time. We discuss the cosmological consequences of a model for the vanishing pressure for the case $k=0$. It has been observed that such models are compatible with the result of recent observations and cosmological term $Λ$ gradually reduces as the universe expands. In this model $Λ$ varies as the inverse square of time, which matches its natural units. The proper distance, the luminosity distance-redshift, the angular diameter distance-redshift, and look back time-redshift for the model are presented in the frame work of higher dimensional space time. The model of the Freese {\it et al.} ({\it Nucl. Phys. B} {\bf 287}, 797 (1987)) for $n=2$ is retrieved for the particular choice of $A_{0}$ and also Einstein-de Sitter model is obtained for $A_{0} = {2/3}$. This work has thus generalized to higher dimensions the well-know result in four dimensional space time. It is found that there may be significant difference in principle at least, from the analogous situation in four dimensional space time.

description: We analyze the dynamics of the neural circuit of the lamprey central pattern generator (CPG). This analysis provides insights into how neural interactions form oscillators and enable spontaneous oscillations in a network of damped oscillators, which were not apparent in previous simulations or abstract phase oscillator models. We also show how the different behaviour regimes (characterized by phase and amplitude relationships between oscillators) of forward/backward swimming, and turning, can be controlled using the neural connection strengths and external inputs.

description: Using the non-interacting Anderson tight-binding model on the Bethe lattice as a toy model for the many-body quantum dynamics, we propose a novel and transparent theoretical explanation of the anomalously slow dynamics that emerges in the bad metal phase preceding the Many-Body Localization transition. By mapping the time-decorrelation of many-body wave-functions onto Directed Polymers in Random Media, we show the existence of a glass transition within the extended regime separating a metallic-like phase at small disorder, where delocalization occurs on an exponential number of paths, from a bad metal-like phase at intermediate disorder, where resonances are formed on rare, specific, disorder dependent site orbitals on very distant generations. The physical interpretation of subdiffusion and non-exponential relaxation emerging from this picture is complementary to the Griffiths one, although both scenarios rely on the presence of heavy-tailed distribution of the escape times. We relate the dynamical evolution in the glassy phase to the depinning transition of Directed Polymers, which results in macroscopic and abrupt jumps of the preferred delocalizing paths when a parameter like the energy is varied, and produce a singular behavior of the overlap correlation function between eigenstates at different energies. By comparing the quantum dynamics on loop-less Cayley trees and Random Regular Graphs we discuss the effect of loops, showing that in the latter slow dynamics and apparent power-laws extend on a very large time-window but are eventually cut-off on a time-scale that diverges at the MBL transition.

Gamma Ray Bursts and Radio Loud Active Galactic Nuclei

Subjects: subject: Astrophysics (astro-ph)

description: We believe that the radiation we receive from Gamma-Ray Bursts (GRBs) and radio loud Active Galacti Nuclei (AGNs) originates from the transformation of bulk relativistic motion into random energy. Mechanisms to produce, collimate and accelerates the jets in these sources are uncertain, and it may be fruitful to compare the characteristics of both class of sources in search of enlightening similarities. I will present some general characteristics of radio loud AGNs and GRBs such as their bulk Lorentz factors and the power of their jets. I will also discuss the way in which the energy in bulk relativistic motion can be transformed into beamed radiation, and consider the possibility that both classes of sources can work in the same way, namely by an intermittent release of relativistic plasma at the base of the jet: shells ejected with slightly different velocities collide at some distance from the central engine, dissipating part of their kinetic energy, and keeping the rest to power the extended radio lobes (in AGNs) or to produce the afterglow (in GRBs).

description: We present three XMM-Newton observations of the ultra-luminous compact X-ray source Holmberg II X-1 in its historical brightest and faintest states. The source was in its brightest state in April 2002 with an isotropic X-ray luminosity of 2e40 erg/s but changed to a peculiar low/soft state in September 2002 in which the X-ray flux dropped by a factor of four and the spectrum softened. In all cases, a soft excess component, which can be described by a simple or multicolor disk blackbody (MCD; kT = 120-170 eV), is statistically required in addition to a power-law continuum (Gamma = 2.4 - 2.9). Both the spectral components became weaker and softer in the low/soft state, however, the dramatic variability is seen in the power-law component. This spectral transition is opposite to the `canonical' high/soft -- low/hard transitions seen in many Galactic black hole binaries. There is possible contribution from an optically thin thermal plasma. When this component is taken into account, the spectral transition appears to be normal -- a drop of the power-law flux and slightly softer blackbody component in the low state.

description: We report the results of a cosmic shear survey using the 4.2m William Herschel Telescope on La Palma, to a depth of R=25.8 (z~0.8), over 4 square degrees. The shear correlation functions are measured on scales from 1' to 15', and are used to constrain cosmological parameters. We ensure that our measurements are free from instrumental systematics by performing a series of tests, including a decomposition of the signal into E- and B-modes. We also reanalyse the data independently, using the shear measurement pipeline developed for the COMBO-17 survey. This confirms our results and also highlights various effects introduced by different implementations of the basic "KSB" shear measurement method. We find that the normalisation of the matter power spectrum on 8 h^{-1}Mpc scales is sigma_8=(1.02+/-0.15)(0.3/Omega_m)^{0.5}, where the 68%CL error includes noise, sample variance, covariance between angular scales, systematic effects, redshift uncertainty and marginalisation over other parameters. We compare these results with other cosmic shear surveys and with recent constraints from the WMAP experiment.
description: 11 pages, 13 figures. Accepted version. Now includes a second, independent analysis of the WHT data using the COMBO-17 pipeline. This confirms our results, within statistical errors. A meticulous comparison of the two methods also highlights some important details of weak shear measurement for the first time
Recurrence Time Statistics for Finite Size Intervals

description: We investigate the statistics of recurrences to finite size intervals for chaotic dynamical systems. We find that the typical distribution presents an exponential decay for almost all recurrence times except for a few short times affected by a kind of memory effect. We interpret this effect as being related to the unstable periodic orbits inside the interval. Although it is restricted to a few short times it changes the whole distribution of recurrences. We show that for systems with strong mixing properties the exponential decay converges to the Poissonian statistics when the width of the interval goes to zero. However, we alert that special attention to the size of the interval is required in order to guarantee that the short time memory effect is negligible when one is interested in numerically or experimentally calculated Poincar{é} recurrence time statistics.

description: Excerpts from the report: As part of the Department of Agriculture's effort to further the consumption and distribution of farm products, the Market Surveys Section of the Market Development Branch, Agricultural Marketing Service, conducted this nationwide sample study of women's attitudes toward cotton and other fibers, particularly as related to certain items of women's clothing. It is expected that this survey, like previous studies of consumer attitudes toward fibers used in women's, men's, and children's apparel, will provide guides for product improvement and prove generally useful to the persons and groups concerned with widening and strengthening the acceptance of materials and garments made of cotton. The sample used in this study was designed to be representative of all women in the United States between 18 and 65 years of age and all homemakers regardless of age. It was selected by the area probability method, set up to assure each household in the United States an equal chance of being included. Personal interviews were conducted with 2,281 women.

description: An experimental approach in conducting NMR measurements at supercritical parameters of state is discussed. A novel design of the high-pressure NMR cell was developed which allowed eliminating the field inhomogeneity and, thus, increasing the sensitivity of the experiment at the supercritical state. Analysis of the MD simulations and NMR data showed that two conformers of ibuprofen dominate in the solution in supercritical CO2 along the critical isochore 1.3 \r{ho}cr(CO2). Conformer populations calculated from MD simulations and from NMR spectra agree with each other

description: Magnetic reconnection before flux cancellation in the solar photosphere when two opposite-polarity photospheric magnetic fragments are approaching one another is usually modelled by assuming that a small so-called "floating current sheet" forms about a null point or separator that is situated in the overlying atmosphere. Here instead we consider the reconnection that is initiated as soon as the fragments become close enough that their magnetic fields interact. The resulting current sheet, which we term a "fin sheet" extends up from the null point or separator that is initially located in the solar surface. We develop here nonlinear analyses for finite-length models of both fin and floating current sheets that extend the previous models that were limited to short floating current sheets. These enable the length of the current sheet to be calculated in both cases as functions of the separation distance of the sources and the reconnection rate, as well as the rate of heating. Usually, the fin current sheet liberates more energy than a floating current sheet.

description: Der Einfluß der weicheleiszeitlichen periglazialen Formung auf die Umgestaltung der Altmoränengebiete wird am Beispiel des im Norddeutschen Tiefland gelegenen Uelzener Beckens untersucht. Dieses Gebiet erhielt seine grundlegende Formung durch das Warthe-Inlandeis und lag während der Weichsel-Eiszeit im periglazialen Bereich. Es werden zwei Beispiele für eine durch fluviale und solifluidale Prozesse verursachte Reliefumkehr im kleinen gezeigt. Eine Abschätzung der Größenordnung der Abtragung im Beckenbereich 1.) seit dem Rückzug des Warthe-Eises und 2.) seit dem Eem-Interglazial wird ermöglicht 1.) durch die Umkehr der Entwässerung nach dem Eiszerfall und 2.) durch die Höhenlage Eem-zeitlicher Ablagerungen über dem heutigen Beckenboden. Danach muß man mit einer allgemeinen Erniedrigung des Beckenbodens um etwa 20 m seit der ausgehenden Warthe-Zeit rechnen; davon sind etwa 10 m allein der weichseleiszeitlichen Abtragung zuzuschreiben.

description: Domain-specific languages (DSLs) are touted as both easy to embed in programs and easy to optimize. Yet these goals are often in tension. Embedded or internal DSLs fit naturally with a host language, while inheriting the host's performance characteristics. External DSLs can use external optimizers and languages but sit apart from the host. We present Sham, a toolkit designed to enable internal DSLs with high performance. Sham provides a domain-specific language (embedded in Racket) for implementing other high-performance DSLs, with transparent compilation to assembly code at runtime. Sham is well suited as both a compilation target for other embedded DSLs and for transparently replacing DSL support code with faster versions. Sham provides seamless inter-operation with its host language without requiring any additional effort from its users. Sham also provides a framework for defining language syntax which implements Sham's own language interface as well. We validate Sham's design on a series of case studies, ranging from Krishnamurthi's classic automata DSL to a sound synthesis DSL and a probabilistic programming language. All of these are existing DSLs where we replaced the backend using Sham, resulting in major performance gains. We present an example-driven description of how Sham can smoothly enhance an existing DSL into a high-performance one. When compared to existing approaches for implementing high-performance DSLs, Sham's design aims for both simplicity and programmer control. This makes it easier to port our techniques to other languages and frameworks, or borrow Sham's innovations "à la carte" without adopting the whole approach. Sham builds a sophisticated and powerful DSL construction toolkit atop fundamental language features including higher-order functions, data structures, and a foreign-function interface (FFI), all readily available in other languages. Furthermore, Sham's approach allows DSL developers to simply write functions, either using Sham or generating Sham, without needing to work through complex staging or partial evaluation systems.

description: Die Gliederung des Postglazials im nordwestdeutschen Flachland beruht auf der Einteilung der Waldentwicklung in pollenanalytisch gut faßbare Zonen. Diese Zonen sind jedoch nur in großen Zügen zeitlich gleichzusetzen. Dagegen lassen sich für den Zeitvergleich eine Reihe von Leithorizonten herausarbeiten, die großklimatisch bedingte Änderungen im Waldbild anzeigen. Als zeitliche Leithorizonte können nicht Veränderungen dienen, die in einer Neueinwanderung von Bäumen bestehen, auch dann nicht, wenn das Erscheinen dieser Holzarten durch Klimaänderungen ermöglicht worden ist, weil in solchen Fällen der Arealerweiterung noch andere Bedingungen hemmend oder fördernd eingreifen. Das wird durch das Beispiel der Buche belegt. Für das nordwestdeutsche Flachland werden 7 zeitliche Leithorizonte herausgestellt, wobei allerdings die Haselmaxima in Ostfriesland nicht klar zu erkennen sind. Für Schleswig-Holstein treten noch 2 weitere Leithorizonte hinzu. Rekurrenzflächen in Mooren sind nicht ohne weiteres zeitlich zu parallelisieren. Ihre Zeitstellung muß durch die Pollenanalyse erbracht werden.

description: Despite its huge agricultural potential, Albania has a sharp trade deficit with agricultural commodities. The main focus of this study is to analyse key determinants of its agricultural export. Here we employ baseline gravity model considering conventional gravity variables for Albanian export flows for the period 1996-2013. The Poisson Pseudo-Maximum Likelihood (PPML) regression is used for stepwise estimations of the augmented gravity model, including effects of Albanian Diaspora, exchange rate and price stability, trade liberalization and institutional distance. Main findings suggest that agricultural export flow increases with increasing economic size, revealing higher impact of importer’s absorbing potential comparatively to Albania’s productive potential. On the other hand, growth in domestic demand, resulting from increase in population, leads to reduction of agricultural export. Moreover, agricultural export flows are determined by low transportation costs (distance), adjacency proximity (sharing common border) and linguistic similarities. Presence of Albanian Diaspora residing in the importing countries facilitates export flows. Results of this study reveal that exchange rate variability has a positive impact, while bilateral institutional distance has diminishing effects on Albanian agricultural exports.

Said properties are measured in Dunkl-Sobolev-type norms in which the same weighted $\mathrm{L}^2$ norm is used to control all the involved differential-difference Dunkl operators, such as those appearing in the Sturm-Liouville characterization of similarly weighted $\mathrm{L}^2$-orthogonal polynomials, as opposed to the partial derivatives of Sobolev-type norms. The method of proof relies on spaces instead of bases of orthogonal polynomials, which greatly simplifies the exposition.

description: Despite its economic magnitude worldwide, the scientific attention to the floriculture sector remains scarce within the borders of the European Union. Focusing on Italy, the aim of this paper is to provide an insight into the floriculture trade for the first time. More specifically, in addition to describing trade dynamics of the floriculture sector both in Italy and in the European Union in recent years, this paper applies a gravity model to investigate and evaluate the role of some major economic and geographical variables as determinants of Italian trade flows of cut flowers and live plants within the European Union, from 2001 to 2013. Among these, findings prove that the most important are the GDP per capita of the European trade partners, as well as their production and consumption volumes.

description: We study the robustness of the determination of the neutrino masses and mixing from the analysis of atmospheric and K2K data under the presence of different forms of phenomenologically allowed new physics in the nu_mu--nu_tau sector. We focus on vector and tensor-like new physics interactions which allow us to treat, in a model independent way, effects due to the violation of the equivalence principle, violations of the Lorentz invariance both CPT conserving and CPT violating, non-universal couplings to a torsion field and non-standard neutrino interactions with matter. We perform a global analysis of the full atmospheric data from SKI together with long baseline K2K data in the presence of nu_mu -> nu_tau transitions driven by neutrino masses and mixing together with sub-dominant effects due to these forms of new physics. We show that within the present degree of experimental precision, the extracted values of masses and mixing are robust under those effects and we derive the upper bounds on the possible strength of these new interactions in the nu_mu--nu_tau sector.

description: This paper, using qualitative research methods, aims to assess the challenges faced by the Philippine Comprehensive Agrarian Reform Program and its extension on the selected cases from five Philippine provinces. In 27 years of its implementation, the agrarian reform has achieved land redistribution of around 7.7 million hectares despite the periodical lack of political will and opposition from landlords, sometimes violent or through protracted legal battles. Support services focus almost exclusively on Agrarian Reform Communities, in which such services are funded mostly through the official development assistance from abroad rather than government’s budget. Limited availability of support services to those agrarian reform beneficiaries located outside of Agrarian Reform Communities prevents them from becoming economically viable producers and seriously taints whatever land distribution may have accomplished. Some reform beneficiaries may have been awarded their land on paper but were not able to take possession of the land or must have abdicated control of it.

description: We examine giant gravitons with a worldvolume magnetic flux $q$ in type IIA pp-wave background and find that they can move away from the origin along $x^4$ direction in target space satisfying $Rx^4=-q$. This nontrivial relation can be regarded as a complementary relation of the giant graviton on IIA pp-wave and is shown to be connected to the spacetime uncertainty principle. The giant graviton is also investigated in a system of N D0-branes as a fuzzy sphere solution. It is observed that $x^4$ enters into the fuzzy algebra as a deformation parameter. Such a background dependent Myers effect guarantees that we again get the crucial relation of our giant graviton. In the paper, we also find a BIon configuration on the giant graviton in this background.

description: Zur Charakterisierung der Anteile von Lössen und Verwitterungsprodukten der liegenden Keuper- und Liasgesteine innerhalb kolluvialer Mischsedimente und holozäner Terrassenkörper erweisen sich in Oberfranken neben Korngrößenverteilungen insbesondere Quarz-Feldspat- und Albit-Mikroklin-Quotienten als geeignete Indizes. Danach sind an den untersuchten bodenerosiv überprägten Flachhängen bevorzugte Abtragung von Löß und Liegendmaterial an den Oberhängen, vorherrschender Durchtransport an den Mittelhängen und Ablagerung von Mischsedimenten an den Unterhängen zu erkennen. In den holozänen Sedimenten der Vorfluter sind Lößderivate demgegenüber nur gering vertreten, woraus auf vorherrschenden Durchtransport dieses Materials in den untersuchten Talstrecken und — im Vergleich mit niedersächsischen Beispielen entsprechender Größenordnung — auf eine regionale Differenzierung der holozänen fluvialen Dynamik geschlossen wird, die möglicherweise auf Unterschiede des Regionalklimas zurückzuführen ist.

description: Network coverage is one of the fundamental requirements of any business of a service provider. Mobile operators are expected to deploy base stations in an effective way in order to cover most of the residential areas of a particular country. Improved network coverage leads to increase total revenue, provide end users with enhanced Quality of Services (QoS) anytime anywhere, and play vital role in the development of telecom sector. In this paper, we measure and statistically analyze network coverage of mobile operators in Afghanistan. Our study is based on primary data collected on random basis from 1,515 mobile phone users of cellular operators. The relationship between “No Network Coverage” in some residential areas and “Satisfaction of Mobile Phone Users” is also investigated. We furthermore propose realistic, feasible and cost-efficient solutions to mobile operators and policy makers in order to expand network coverage to non-covered residential areas as well as enhance the performance of networks in existing covered areas of the country.
Lithostratigraphy and paleoenvironmental development recorded in the coastal cliffs of SE Usedom, Germany

description: Die glazialen Sedimente der Küstenkliffe von Usedom, NE-Deutschland, sind unter besonderer Berücksichtigung der Rekonstruktion der Entwicklung des Paläomiljeus untersucht worden. Im unteren Teil des Anschnittes ist der stark gescherte Langerberg-Till aufgeschlossen. Dieser ist wahrscheinlich Teil eines marginalen Stauchmoränenkomplexes, der während eines Eisvorstoßes, vermutlich aus dem NW, abgelagert worden ist. Der Vorstoß hinterließ einen weitflächigen marginalen Eiszerfallskomplex, auf den der Ückeritz-Sand, zum Teil in wassergefüllten Becken aufgeschüttet wurde. Supraglazialer Schutt wurde sowohl in Form von Diamiktit-Lagen im Sand, als auch als sporadische Diamiktdecke auf dem Sand abgesetzt. Die untersuchte Sequenz entspricht der letzten weichselzeitlichen Deglaziation in diesem Gebiet. Die Einheiten können mit den jüngsten glazialen Ablagerungen im Westteil von Wolin, NW-Polen, korreliert werden.

Localized behavior in the Lyapunov vectors for quasi-one-dimensional many-hard-disk systems

description: We introduce a definition of a "localization width" whose logarithm is given by the entropy of the distribution of particle component amplitudes in the Lyapunov vector. Different types of localization widths are observed, for example, a minimum localization width where the components of only two particles are dominant. We can distinguish a delocalization associated with a random distribution of particle contributions, a delocalization associated with a uniform distribution and a delocalization associated with a wave-like structure in the Lyapunov vector. Using the localization width we show that in quasi-one-dimensional systems of many hard disks there are two kinds of dependence of the localization width on the Lyapunov exponent index for the larger exponents: one is exponential, and the other is linear. Differences, due to these kinds of localizations also appear in the shapes of the localized peaks of the Lyapunov vectors, the Lyapunov spectra and the angle between the spatial and momentum parts of the Lyapunov vectors. We show that the Krylov relation for the largest Lyapunov exponent $λ\sim-ρ\lnρ$ as a function of the density $ρ$ is satisfied (apart from a factor) in the same density region as the linear dependence of the localization widths is observed. It is also shown that there are asymmetries in the spatial and momentum parts of the Lyapunov vectors, as well as in their $x$ and $y$-components.

description: Ein rezenter Boden und zwei begrabene Paläoböden, Einheiten II-III-IV (oberer) und IV (unterer)-V, liefern wichtige Informationen über Paläoklima und Abflußverhältnisse in den Virunga-Bergen von trockeneren zu feuchteren paläoklimatischen Phasen des Spätglazials bis zu mittleren postglazialen Zeiten. Zusammenfassend betrachtet, weist die stratigraphische Abfolge zunächst auf eine Verwitterungsperiode des Festgesteins hin, der eine Phase folgt, in der tuffige Schichten abgelagert wurden. Die Zeit war von einer Verwitterung unter trockeneren und vielleicht kälteren Bedingungen begleitet. Später, während des letzten Glazials, kam es bei verstärkter Aktivität der Flüsse zur Sedimentation von Schwemmlandablagerungen, die von einer dünnen Tuff-Schicht überdeckt wurden. Diese Sedimente sind intensiver verwittert als die liegenden Schichten. Der rezente Boden zeigt eine vergleichsweise geringe Verwitterung mobiler Elemente, was darauf hindeutet, daß die Klimaverhältnisse im späten Mittel-Holozän und Spät-Holozän etwas trockener und vielleicht kühler waren als im Früh-Holozän. Die Geochemie der drei Böden zeigt eine bedeutende Abnahme von Na, Ca und K im mittleren Paläoböden im Vergleich zum älteren Paläoböden und zu den rezenten Böden. Eisen als ein wichtiger Indikator für das Paläoklima deutet daraufhin, daß die mittleren Einheiten II und III des oberen Paläobodens unter feuchteren Klimabedingungen als heute entstanden sind. Die Radiokarbon-Datierungen des mittleren Paläobodens zeigen, daß dieser Boden einer sub-aerischen Verwitterung vom Kalambo-Interstadial (» 25000 Jahre vor heute) bis zum Mittel-Holozän ausgesetzt war. Die gesamte Verwitterung im mittleren Abschnitt ist zu weit fortgeschritten und während des Holozäns entstanden. Die relativ hohe Konzentration von Th in den anstehenden Festgesteinen, Tuffen, Schwemmlandsedimenten und Hangrutschmassen zeigt, daß Th die Quelle der Radioaktivität ist, von der andere Autoren aus den Virunga-Bergen berichten.

description: USDA’s Supplemental Nutrition Assistance Program (SNAP) is designed to increase the food purchasing power of low-income households. A recent USDA survey—the National Household Food Acquisition and Purchase Survey (FoodAPS)—provides a unique opportunity to gain a comprehensive understanding of the food spending of SNAP households. This study finds that, when adjusted for household size and composition, average food spending in SNAP households is lower than in other U.S. households, even those that are eligible for SNAP but choose not to participate. Food-at-home spending accounts for a greater share of the total food expenditures of SNAP households than of other households. SNAP benefits account for over 60 percent of the average food-at-home expenditures of SNAP households. They also play a strong role in the food budgets of households with children and those in poverty, especially those in deep poverty. Among both SNAP households and eligible nonparticipant households, those that are food secure spend more on food than those that are food insecure. Finally, this study finds clear evidence of a cyclical pattern in the food spending of SNAP households across the benefit month.
