description: Angular correlations of two and more particles are a sensitive probe of the initial state and the transport properties of the system produced in heavy-ion collisions. Two recent results of the ALICE collaboration are presented. Event-shape engineering, a novel method, is applied to Pb-Pb collisions which splits events within the same centrality interval into classes with different average flow. The results indicate an interplay between radial and elliptic flow likely related to the initial-state eccentricity. In pp and p-Pb collisions, recent results revealed intriguing long-range correlation structures reminiscent of features observed in heavy-ion collisions. The use of forward detectors allowed to show that long-range correlation structures persist also at large rapidities in p-Pb collisions.

Kulturwandel und Klima im 13./12. Jahrhundert v. Chr. – Das Beispiel Kastanas in Nordgriechenland
Creators: name: Falkenstein, Frank
Publisher: name: Offa

description: In den Jahrzehnten um 1200 v. Chr. fand im östlichen Mittelmeerraum ein Systemkollaps der spätbronzezeitlichen Palastgesellschaften statt. Begleiterscheinungen der vielschichtigen Krise waren kriegerische Konflikte, der Niedergang der Palastgesellschaften und des Fernhandels sowie Migrationen. Seit den 1960er Jahren favorisieren manche Autoren klimatische Faktoren, insbesondere Dürren, als Auslöser für den Niedergang der mykenischen Palastgesellschaft. Jüngeren paläoklimatologischen Studien zufolge lassen sich zwei verschiedene Klimaphänomene für das späte 13. und 12. Jh. v. Chr. fassen. Dies ist zum einen eine langzeitige graduelle Abkühlung der nördlichen Hemisphäre nach einer besonders warmen Klimaphase, zum anderen ein einschneidendes Klimaereignis, dessen Gipfelpunkt dendrochronologisch auf die Jahre 1159 1141 v. Chr. datiert wird. Der prähistorische Siedlungshügel von Kastanas in Makedonien (Nordgriechenland) bietet aufgrund der multidisziplinären Untersuchungen mit zeitlich hoch aufgelösten Ergebnissen ein besonders geeignetes Fallbeispiel für die diachrone Untersuchung des Kulturwandels und der Subsistenzwirtschaft am Ende der ägäischen Bronzezeit (SH III B / SH III C) im Hinblick auf das Klima. In den Schichten 15–14 a (SH III B / SH III C Früh) von Kastanas lässt sich anhand der archäobotanischen und archäozoologischen Ergebnisse ein Niedergang der Subsistenzwirtschaft herausstellen. Am Kulminationspunkt der Ernährungskrise am Übergang von SH III C Früh zu SH III C Entwickelt (Schichten 14 a–13, ca. 1160–1140 v. Chr.) ist in der Ansiedlung ein Kulturbruch fassbar, der mit der Einwanderung und Niederlassung einer Bevölkerung donauländischer Herkunft in Verbindung gebracht werden kann. Der spätbronzezeitliche Kulturgang in Kastanas zeigt deutliche Indikatoren eines komplexen Krisenszenarios, wie es im Hinblick auf die kontemporäre Klimaentwicklung durchaus zu erwarten wäre.

Three tests of dimensionality in structural equation modeling: a Monte Carlo simulation study
Creators: name: Jiang, Niantao
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The issue of dimensionality is essential to social science research but few researchers have empirically tested the dimensionality of theoretical constructs. One main reason is the uncertainty of how best to proceed. With the development of structural equation modeling with latent variables, several tests are available for researchers to choose. In this study, drawing on statistical theory and prior researches, I empirically assess the performance of likelihood ration test, confidence interval test, and vanishing tetrads test using data generated from Monte Carlo simulations. The study results show the likelihood ratio test did reasonably well. It does not show obvious signs of impact of the violation of boundary condition when testing for dimensionality. While overall the confidence interval test method appears to be too conservative, the vanishing tetrads tests for dimensionality works best for models with few indicators, but less well in larger models and smaller sample sizes.
Phenotype Characterization of Mice with Targeted Deletions of Dlx Enhancers

description: The Distal-less homeobox (Dlx) genes encode a group of transcription factors that are involved in early vertebrate development of limbs, sensory organs, branchial arches and the forebrain. In the forebrain, four Dlx genes, Dlx1, Dlx2, Dlx5, Dlx6, play essential role in the differentiation and proper migration of GABAergic interneurons to the cortex. Dlx genes are organized in convergently transcribed bigene clusters and each cluster includes a short intergenic region harboring cis-regulatory elements (CREs): specifically, the Dlx1/2 cluster includes I12b and I12a CREs, while Dlx5/6 harbors I56i and I56ii. In an effort to determine the regulatory role of the CREs on Dlx expression and forebrain development, I characterized mice with an I56i deletion and both I12b and I56i deletions. At late embryonic stage (E18.5) and the adult stage (P35), both mutants had similar expression levels of Dlx2 and Gad2 gene, encoding enzyme glutamic acid decarboxylase that is responsible for synthesis of GABA. Mutant mice showed impaired expression levels of Dlx5. The expression levels of Gad1 were decreased in ΔI56i mutants but increased in ΔI12b/I56i mutants at E18.5, and both adult mutants had comparable expression of Gad1 as wildtype mice. Together with previous in situ hybridization results of mice at earlier stages (E11.5, E14.5), my data show that Dlx CREs have different levels of activity in regulating the expression of Dlx genes at different developmental stages. The mutations of I56i and I12b CREs did not affect the development of two subtypes of GABAergic neurons (calbindin and calretinin expressing neurons) in the forebrain. Compared to wildtype mice, both mutants had hypersociability and deficits of memory and learning ability. This opens the possibility that the deletions of Dlx intergenic CREs caused some developmental abnormalities and, therefore affected the behavior of the mice. Through studying the mice lacking Dlx intergenic CREs, I gained a better understanding of the role that I56i and I12b play in the regulation of the expression of Dlx genes, the development of GABAergic neurons, and the social and cognitive behavior.
Exploring the Mathematical Identities of Successful Latino High School Students

description: Using Martin’s (2000) framework, this study examined the mathematical identity and socialization of successful Latino students in a small community in the rural South. Positioned in the New Latino Diaspora (Murillo, 2002; Villenas, 2002), I provide a counternarrative to the gap-gazing dominant narrative of Latinos in mathematics education research, which historically has primarily focused on lack of academic success among Latino students in comparison to their White, middle class counterparts. These case studies explore not only how the ways in which students defined their own mathematical identity, but also how parents, teachers, and peers influence students’ mathematical identities. The four high school students presented as cases in this study all exhibit positive mathematical identities and show relatively high levels of interest in continuing their education in STEM fields. The students identified being successful in mathematics as innate ability, as opposed to an acquired or nurtured skill, and identified mathematics as closed system, only available to those with a pre-existing aptitude for mathematics. They expressed appreciation for mathematics as a static, finite school subject having little access to experiencing mathematics as a field of open inquiry or real life application. The students also saw the importance of mathematics as being more about fulfilling a prerequisite for higher education rather than a field of high interest or passion. These students’ self-identified their success in mathematics and defined this success primarily by comparing themselves to their less mathematically successful peers in school. These students also expressed concern over a perceived negative effect of limited opportunities for higher education on their peers as dictated by documentation status. There were exhibited mixed perceptions on the role of parents’ perceptions of mathematics, and there was very limited emphasis given to the role of teachers in the creation of positive mathematical identities. For these students, academic and mathematical success was often associated with a negotiated relationships with their peers and/or family while teachers seemed to be, at best, benign transmitters of mostly algorithms and facts. Implications for mathematics teachers and mathematics education researchers are discussed, such as the possibilities offered by critical mathematics pedagogies.

description: Cette thèse porte sur les figures contemporaines de la « patiente » au sein du système de santé mentale ontarien. Le contexte de désinstitutionnalisation des services de santé mentale ainsi que les transformations au niveau de la normativité sociale servent de trame de fond à cette thèse. Ces changements se reflètent dans nos attentes envers les patientes, qui ne doivent plus qu’obéir de manière passive aux professionnelles de la santé, mais doivent plutôt faire preuve d’autonomie, d’initiative et de responsabilité individuelle quant à leur cheminement thérapeutique. Ces normes sociales sont véhiculées par des logiques d’intervention telles que l’empowerment, le rétablissement, et la participation des patientes dans des instances systémiques de l’institution. En d’autres mots, les patientes doivent « s’activer » plus que jamais. C’est précisément sur cette injonction que s’est penchée cette thèse, par le biais d’une ethnographie menée auprès de deux terrains de recherche et inspirée par les travaux de Goffman (1961) sur la carrière morale et Foucault (1975) sur les normes sociales. Le premier terrain, une unité de soins aigus en santé mentale, montre par le biais d’une cartographie de l’espace disciplinaire que l’autonomie à laquelle doivent aspirer les patientes est balisée par des exigences normatives de docilité, d’obéissance et de « collaboration » avec l’équipe traitante. Le second terrain, un comité consultatif de « clientes » d’une institution de santé mentale de troisième ligne, montre que les patientes peuvent maintenant jouer un rôle au sein des politiques de l’institution et investir une « carrière » plus valorisée de patiente. Cependant, celles-ci demeurent parfois reléguées à leur statut de « patiente », leur autonomie se voyant balisée par les objectifs institutionnels. Le comité doit plutôt agir en tant que « relais » de l’institution, notamment par la construction d’un récit d’aveu qui promeut l’image d’une patiente « idéale ». Bref, cette thèse trace les contours de deux figures de la patiente se situant sur un même continuum (activation individuelle et activation collective). Finalement, ce travail montre la prédominance encore aujourd’hui des disciplines, malgré l’omniprésence de discours soi-disant émancipateurs. En fin d’analyse, des pistes de réflexion, d’intervention et de recherche sont proposées afin de mieux répondre aux besoins des personnes ayant un vécu en santé mentale et de limiter les effets potentiellement néfastes des interventions de la relation d’aide.

Analytical Methodology to Predict the Behaviour of Multi-Panel CLT Shearwalls Subjected to Lateral Loads

description: The increasing demand for more sustainable construction has led to the development of new structural systems that include wood as building material. Cross laminated timber (CLT) has been identified as a potential system to address this need and to provide alternative options in the range of low- to medium-rise construction. The appeal in using CLT as a shearwall is driven by the combination of the rigid panels and small dimension fasteners, which allows for significant energy dissipation in the structure. However, there is currently no reliable analytical model to accurately predict the behaviour of multi-segment CLT shearwalls. The current study aims to develop an analytical model capable of predicting the elastic and plastic phases associated with the behaviour of multi-panel CLT shearwalls. The model describes the wall behaviour as a function of the connectors’ properties in terms of stiffness, strength and ductility. This dependency means that the only input required in the model is the behavioural parameters of the connections. The proposed model contains six cases with a total of 36 different failure mechanisms. Two final wall behaviours were developed, and it was found that behaviour (i.e. single wall) could be achieved if the yielding in the hold-down occurred prior to yielding in the panel joints. Inversely, the other behaviour (i.e. coupled panels) was achieved if the yielding in the vertical joint occur prior to yielding in the hold-down. The analytical model was validated using a numerical model, and the results of the comparison showed very close match between the two models. The study proposed simplified design provisions with the aim to optimize the walls ductility (CP behaviour) or strength and stiffness (SW behaviour).

description: Ausgehend von Neufunden anthropomorpher und zoomorpher Figuralplastik aus der spätneolithischen Siedlung Okolište in Bosnien-Herzegowina sind in dem vorliegenden Beitrag einige bisher vernachlässigte Aspekte dieser Fundgattung thematisiert: Einerseits können unterschiedliche Darstellungsmodi und Größenklassen aufgezeigt werden, die mit herstellungstechnischen Unterschieden und möglicherweise auch mit verschiedenen Funktionen verbunden werden können. Im Gegensatz zu anderen neolithischen Siedlungen Südosteuropas lassen die Fragmentierungsmuster der Statuetten in Zentralbosnien keine Ungleichgewichte bestimmter Körperteile erkennen, die vielfach als ein Indiz für intentionelle Zerstörungen gesehen werden. Die chronologische Auswertung lasst eine zeitliche Variabilität hinsichtlich der Häufigkeit und möglicherweise auch bezüglich der Qualität der Statuetten erkennen. Anhand der Analyse von Fundhäufigkeiten können innerhalb Zentralbosniens keine Unterschiede festgestellt werden, die auf Funktionsunterschiede zwischen Siedlungen hindeuten. Dagegen sind Figurinen deutlich seltener als in benachbarten Regionen. Indem die Funddichte mit der Anzahl von Häusern und bestimmten Hausinventaren verbunden werden kann, werden teilweise soziale Bezüge der Funde zu politisch und wirtschaftlich besonders aktiven Haushalten deutlich.

Negotiating murder: Wehrmacht soldiers and participation in atrocities, 1941-1942
Creators: name: Beorn, Waitman W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: How did ordinary German soldiers confront atrocities and their complicity in them? This study investigates the complexities of participation and non-participation in spontaneous acts of violence in one unit on the eastern Front. It begins by examining what kinds of propaganda soldiers were exposed to and what kinds of beliefs and worldviews they expressed in letters home. In September 1942, the 4th Panzer Signal company murdered thirty to forty Jews in the tiny Soviet town of Peregruznoje, apparently on the initiative of the unit commander. A case study of this unit illuminates a twisted terrain of choices, pressures, norms, and organizational culture that helps explain why some men (and units) killed and others did not. This work argues that the kinds of “perpetrators” among Wehrmacht soldiers fall along a continuum of response: an activist core led by the commander, followers who went along, and others who evaded participation.

description: Medical image segmentation has made significant progress when a large amount of labeled data are available. However, annotating medical image segmentation datasets is expensive due to the requirement of professional skills. Additionally, classes are often unevenly distributed in medical images, which severely affects the classification performance on minority classes. To address these problems, this paper proposes Co-Distribution Alignment (Co-DA) for semi-supervised medical image segmentation. Specifically, Co-DA aligns marginal predictions on unlabeled data to marginal predictions on labeled data in a class-wise manner with two differently initialized models before using the pseudo-labels generated by one model to supervise the other. Besides, we design an over-expectation cross-entropy loss for filtering the unlabeled pixels to reduce noise in their pseudo-labels. Quantitative and qualitative experiments on three public datasets demonstrate that the proposed approach outperforms existing state-of-the-art semi-supervised medical image segmentation methods on both the 2D CaDIS dataset and the 3D LGE-MRI and ACDC datasets, achieving an mIoU of 0.8515 with only 24% labeled data on CaDIS, and a Dice score of 0.8824 and 0.8773 with only 20% data on LGE-MRI and ACDC, respectively.

description: Die vorgelegten Daten lassen eine Veränderung der Vegetation im Bereich des Visoko-Beckens erkennen. Trotz des Nachweises selektiver Nutzung der Vegetation durch den Menschen, zumindest während des späten Äneolithikums, konnten verschiedene Einblicke in die Entwicklung der Gehölzvegetation im Visoko Becken erarbeitet werden. Ob die hohen Anteile von Maloideae in den spätneolithischen Schichten auf eine selektive Nutzung dieser Gehölze als Feuerholz hinweisen oder ob dies darüber hinaus den regelmäßigen Schnitt dieser Gehölze widerspiegelt, um ein verstärktes Blühen und Fruchten zu fördern, kann anhand der Holzkohleuntersuchungen nicht entschieden werden. Wenngleich Funde von verkohlten Kerngehäusen von Apfel dessen Genuss nachweisen. Das Verschwinden der Kiefer kann insbesondere vor dem Hintergrund veränderter hydrologischer Bedingungen mit dem Wegfall flachgründiger Standorte in Zusammenhang gebracht werden. Die Ausbreitung der Hainbuche fand in Zentralbosnien deutlich später statt als im kroatischen Küstengebiet. Gründe für diese Ausbreitung sind jedoch nicht festzustellen. Ob sich eine veränderte Nutzung der Wälder oder Änderungen in Böden und Hydrologie auf diese Verschiebung der Vegetationszusammensetzung auswirkten, muss durch weitere Untersuchungen von geomorphologischer und vegetationskundlicher Seite geklärt werden.

description: In magnetically-doped quantum dots changing the carrier occupancy, from open to closed shells, leads to qualitatively different forms of carrier-mediated magnetic ordering. While it is common to study such nanoscale magnets within a mean field approximation, excluding the spin fluctuations can mask important phenomena and lead to spurious thermodynamic phase transitions in small magnetic systems. By employing coarse-grained, variational, and Monte Carlo methods on singly and doubly occupied quantum dots to include spin fluctuations, we evaluate the relevance of the mean field description and distinguish different finite-size scaling in nanoscale magnets.

description: The abundance anomalies in lambda Boo stars are popularly explained by element-specific mass inflows at rates that are much greater than empirically-inferred bounds for interstellar accretion. Therefore, a lambda Boo star's thin outer envelope must derive from a companion star, planet, analogs to Kuiper Belt Objects or a circumstellar disk. Because radiation pressure on gas-phase ions might selectively allow the accretion of carbon, nitrogen, and oxygen and inhibit the inflow of elements such as iron, the source of the acquired matter need not contain dust. We propose that at least some lambda Boo stars accrete from the winds of hot Jupiters.

Archäobotanische Untersuchungen am bronzezeitlichen Tell von Százhalombatta-Földvár an der Donau in Ungarn

description: Im mittelbronzezeitlichen Tell von Százhalombatta- Földvár stellten Einkorn (Triticum monococcum) und Spelzgerste (Hordeum vulgare) die Hauptgetreide dar mit den subdominanten Getreiden „neuem Spelzweizentyp“ (wohl Triticum timopheevi) und Emmer (Triticum dicoccum). Zudem treten Dinkel (Triticum spelta), Rispenhirse (Panicum miliaceum) und Nacktweizen (Triticum aestivum/durum/turgidum) als Beigetreide auf. Ob die Getreidearten Nacktgerste (Hordeum vulgare var. Nudum), Roggen (Secale cereale) und Hafer (Avena sp.) vor Ort eigenständig angebaut wurden, darf bezweifelt werden. Die Ergebnisse von Százhalombatta Földvár folgen damit dem bislang für Ungarn ermittelten Trend: Dominanz des Anbaus von Einkorn während der Mittelbronzezeit. Die Bedeutung des „neuen Spelzweizentyps“ im Pannonischen Becken kann derzeit nicht eingeschätzt werden, in Százhalombatta- Földvár steht er nach Spelzgerste an dritter Stelle. An Ölsaaten sind Leindotter (Camelina sativa), Saflor/Öldistel (Carthamus tinctorius), Lein (Linum usitatissimum) und Mohn (Papaver somniferum) nachgewiesen. Der älteste Nachweis für Saflor/Öldistel in Ungarn ist besonders hervorzuheben. Bei den Hülsenfrüchten sind Linse (Lens culinaris) und Erbse (Pisum sativum) dominant, bei Subdominanz von Linsenwicke (Vicia ervilia) und Ackerbohne (Vicia faba). Die häufigsten Nachweise von Sammelfrüchten gehören zu Kornelkirsche/Dirndl (Cornus mas). Die Wildpflanzennachweise (mindestens 113 verschiedene Arten) stammen überwiegend von anthropogenen Standorten wie Äckern, dem Siedlungsbereich selbst und weiteren ruderalen Standorten. Gute Bodenbedingungen der Äcker und die steppenartige Wildvegetation sowie Standorte der Donauniederung werden durch die ermittelten Arten angezeigt. Die Magerung des Hüttenlehms wurde nicht durch Entspelzungsabfälle der Spelzweizenarten, sondern durch systematische Verwendung von Wildgräsern vorgenommen. Der einzige Nachweis von Weinrebe (Vitis vinifera/sylvestris) erfolgte durch die Bestimmung eines Abdruckes eines Weinkernes im Hüttenlehm.

Myth, mystification, and the dialectic of the scapegoat: rhetorical transformations in Mumia Abu-Jamal's Live from death row
Creators: name: Fifield, Jessica Kathelene
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This essay explores rhetorical transformations in Mumia Abu-Jamal's Live from Death Row that function to expose and contest social inequalities. Pentadic analysis is used to explicate the transformation of scene into agency and illuminate justice as both a motive term and a cultural myth. The essay extends Burke's argument that the establishment of a scapegoat represents one form of mystification, and examines how the dialectic of the scapegoat functions to demystify justice. By shifting justice from an ultimate term into the dialectic, Mumia challenges rhetorics of dehumanization that are (re)produced in discursive and ritual practices of legal, judicial, and penal institutions and transforms understandings of death penalty politics and practice.

description: Modern experiments on neutron and allowed nuclear $β$ decay search for new semileptonic interactions, beyond the ``left-handed'' electroweak force. We show that ongoing and planned $β$-decay experiments, with isotopes at rest and in flight, can be exploited as sensitive tests of Lorentz invariance. The variety of correlations that involve the nuclear spin, the direction of the emitted $β$ particle, and the recoil direction of the daughter nucleus allow for relatively simple experiments that give direct bounds on Lorentz violation. The pertinent observables are decay-rate asymmetries and their dependence on sidereal time. We discuss the potential of several asymmetries that together cover a large part of the parameter space for Lorentz violation in the gauge sector. High counting statistics is required.

Die symbolische Bedeutung von Pflanzen kann der moderne Mensch nur noch aus der volkskundlichen Literatur erschließen und diese zahlreichen Informationen helfen, archäologische Pflanzenfunde in einem neuen Licht erscheinen zu lassen. Die vorliegende deutsche Version meines Artikels, der meinem langjährigen Kollegen Helmut Kroll gewidmet ist, präsentiert die pflanzlichen Grabbeigaben aus 14 neuzeitlichen Bestattungen im Dom zu Helsingør auf der Insel Seeland in Dänemark. Die Gräber datieren zwischen dem 17. und 18. Jh. und stammen somit aus den dänischen Epochen der Renaissance, des Barock und des Rokoko. Das Alter der Toten, ihre Namen und der Todeszeitpunkt sind teilweise bekannt. Kindern wurden andere Pflanzen als Frauen und Männern mit ins Grab gelegt. Da jahreszeitlich bedingt viele Pflanzen zum Zeitpunkt der Bestattung nicht in der Natur gesammelt werden konnten, schließen wir auf eine gezielte Ernte und Aufbewahrung von Trockenblumensträußen. Aus diesem Vorrat wurde dann bewusst ausgewählt.

description: We present a set of experimental results identifying various effects that govern the carrier dynamics of self-catalyzed GaAs/AlGaAs core-shell nanowires (NWs) grown by molecular beam epitaxy i.e. surface recombination velocity, surface charge traps, and structural defects. Time-resolved photoluminescence of NW ensemble and spatially-resolved cathodoluminescence of single NWs reveal that emission intensity, decay time and carrier diffusion length of the GaAs NW cores strongly depend on AlGaAs shell thickness but in a non-monotonic fashion. Although 7 nm-AlGaAs shell can efficiently suppress the surface recombination velocity of the GaAs NW cores, the effect of the band bending caused by the surface charges remains dominant if the shell thickness is less than 50 nm; that is, the carrier diffusion length is smaller in the NWs with a thinner shell caused by a stronger carrier scattering at the core/shell interface. If the AlGaAs shell thickness is larger than 50 nm, the luminescence efficiency of the GaAs NW cores starts to be deteriorated, ascribed to the defect formation inside the AlGaAs shell evidenced by transmission electron microscopy.

description: The heating mechanisms of solar white-light flares remain unclear. We present an X1.0 white-light flare on 2022 October 2 (SOL2022-10-02T20:25) observed by the Chinese \ha\ Solar Explorer (CHASE) that provides two-dimensional spectra in the visible light for the full solar disk with a seeing-free condition. The flare shows a prominent enhancement of $\sim$40\% in the photospheric \fe\ line at 6569.2 Å, and the nearby continuum also exhibits a maximum enhancement of $\sim$40\%. For the continuum near the \fe\ line at 6173 Å from the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO), it is enhanced up to $\sim$20\%. At the white-light kernels, the \fe\ line at 6569.2 Å has a symmetric Gaussian profile that is still in absorption and the H$α$ line at 6562.8 Å displays a very broad emission profile with a central reversal plus a red or blue asymmetry. The white-light kernels are co-spatial with the microwave footpoint sources observed by the Expanded Owens Valley Solar Array (EOVSA) and the time profile of the white-light emission matches that of the hard X-ray emission above 30 keV from the Gamma-ray Burst Monitor (GBM) on Fermi. These facts indicate that the white-light emission is qualitatively related to a nonthermal electron beam. We also perform a radiative hydrodynamic simulation with the electron beam parameters constrained by the hard X-ray observations from Fermi/GBM. The result reveals that the white-light enhancement cannot be well explained by a pure electron-beam heating together with its induced radiative backwarming but may need additional heating sources such as \alfven\ waves.

description: Predicting the future evolution of complex systems is one of the main challenges in complexity science. Based on a current snapshot of a network, link prediction algorithms aim to predict its future evolution. We apply here link prediction algorithms to data on the international trade between countries. This data can be represented as a complex network where links connect countries with the products that they export. Link prediction techniques based on heat and mass diffusion processes are employed to obtain predictions for products exported in the future. These baseline predictions are improved using a recent metric of country fitness and product similarity. The overall best results are achieved with a newly developed metric of product similarity which takes advantage of causality in the network evolution.
Change of Land Use during the Last Two Millennia as Indicated in the Pollen Record of a Profundal Core from Mindelsee, Lake Constance Region, Southwest Germany
Creators: name: Rösch, Manfred
Publisher: name: Offa
Year: 2013

description: The pollen content of the core from the centre of the Mindelsee, Southwest Germany, covering the last two millennia, was analysed with high temporal resolution, resulting in a diagram with 215 samples. The results were discussed in terms of human impact and anthropogenic changes and in terms of pollen diversity. Pollen diversity and human impact are correlated until the 19th century. The strongest human impact occurs in the 5th/6th century A.D., between the 10th and 12th centuries A.D. and finally from the late 17th to early 20th centuries A.D. Among the pollen types occurring sporadically there are a lot of useful plants as well as crop weeds. Some other plants from the core not discussed here are presented in Figure 7.

description: For binary systems with an unseen primary and a luminous secondary, the astrometric wobble of the secondary could be used to study the primary. With Gaia, it is possible to measure the mass of the black hole or neutron star with a luminous companion (hereafter BH/NS-LC). Our aim is to provide a method for predicting Gaia's ability in measuring the mass of BH/NS-LCs. We also tried to estimate the number of solvable BH/NS-LCs using Gaia. We used a realistic Markov chain Monte Carlo simulation of mock Gaia observations to obtain a relation between the uncertainty of mass measurement of the primary in BH/NS-LCs with the observable variables of the secondary astrometric orbit. Furthermore, we used the MOBSE code to evolve a Galactic BH/NS-LC sample with a combined Milky Way model. Our relation is applied to this sample to estimate the number of solvable BH/NS-LCs. We derived a good relation between the mass uncertainty and the binary parameters. For the first time, we show the quantitive influence of the period P, inclination i, eccentricity e, and ecliptic latitude $β$ to the mass measurement. Our results suggest that $48^{+7}_{-7}$ BH-LCs and $102^{+11}_{10}$ NS-LCs are solvable during a 5 yr Gaia mission. We also give the distribution of the distance and apparent magnitude of the Gaia solvable BH/NS-LCs. This solvable sample would be increased by additional spectroscopic data or a prolonged Gaia mission. The mass uncertainty relation could be used in future simulations of BH/NS-LCs observed by Gaia. The prediction of the solvable BH/NS-LCs is not only influenced by the process in generating the Galactic BH/NS-LC sample, but is also affected by our uncertainty relation. In particular, the relations of parameters such as $[P, e, i, β]$ are very useful to correct the selection effect in the statistic results of the future BH/NS-LC sample observed by Gaia.

Die eisenzeitliche Siedlung von Kobern-Sürzerhof „Morsweiden“, Kreis Mayen-Koblenz, im Landschaftsraum des Maifeld-Pellenzer Hügellandes
Creators: name: Jost, Cliff A.
Publisher: name: Offa
Year: 2013

description: Die eisenzeitliche Siedlung von Kobern-Sürzerhof „Morsweiden“ wurde 1999 beim Bimsabbau entdeckt. Sie liegt im Maifeld-Pellenzer Hügelland, einem bekannten Siedlungsraum des Mittelrheinischen Beckens, der während der älteren Eisenzeit dicht mit einzelnen Hofstellen überzogen war. Die Siedlung von Kobern „Morsweiden“ gehört dabei zu den wenigen Siedlungsplätzen, die über die Späthallstatt- und Frühlatènezeit hinaus auch noch während der Mittellatènezeit und bis in die Spätlatènezeit hinein benutzt wurden. Aus einem kleinen Grubenhaus mit Zweipfostengrundriss von rund 3,10 × 1,80 m (Fundstelle 83) und einer Siedlungsgrube von zylindrischer Form (Fundstelle 85) wurden Bodenproben für archäobotanische Untersuchungen entnommen. Während das Fundgut aus dem Grubenhaus in eine frühe Phase der Spätlatènezeit (Latène D1, ca. 150–100 v. Chr.) gehört, weist das Fundmaterial aus Grube 85 in die Mittellatènezeit (Latène C, ca. 250–150 v. Chr.), einer Epoche, aus der bisher nur sehr wenige Fundkomplexe bekannt sind. Die Bestimmung und Auswertung der Pflanzenreste ermöglicht daher einen aufschlussreichen Vergleich zwischen den mittel- und spätlatènezeitlichen Pflanzen (siehe S. 307 ff. Beitrag M. König in diesem Band). Chronologisch lassen sie sich an die von Helmut Kroll gewonnenen grundlegenden Ergebnisse zum pflanzlichen Fundgut der Späthallstatt- und Frühlatènezeit (Hallstatt D, Latène A und B, ca. 600/570–250 v. Chr.) aus der nur etwa 15 km entfernt liegenden Siedlung von Wierschem anschließen.

All on the Family: Informal Caregiving in America
Creators: name: Tate, Anne J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The purpose of this thesis is to bring more attention to "family caregivers," or those who provide unpaid assistance to sick or aging relatives, often to the detriment of their own physical and mental health. More than 30 million family, or "informal," caregivers are responsible for the care of elderly spouses, siblings and parents - many of whom have Alzheimer's disease or another dementing illness - and the size of this caregiving population is about to increase as life expectancy increases and baby boomers age. This thesis assesses the literature and media coverage published heretofore on the subject of informal caregiving in America, and, through a series of five family profiles and an article on a local respite program, adds to the growing body of literature on this significant national issue.

description: A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear stress parallel to the crack front (mode III). We investigate facet propagation and coarsening using in-situ microscopy observations of fracture surfaces at different stages of quasi-static mixed-mode crack propagation and phase-field simulations. The results demonstrate that the bifurcation from propagating planar to segmented crack front is strongly subcritical, reconciling previous theoretical predictions of linear stability analysis with experimental observations. They further show that facet coarsening is a self- similar process driven by a spatial period-doubling instability of facet arrays with a growth rate dependent on mode mixity. Those results have important implications for understanding the failure of a wide range of materials.
