description: The generalized Chaplygin gas model is characterized by the equation of state $p = - \frac{A}{ρ^α}$. It is generally stated that the case $α= 0$ is equivalent to a model with cosmological constant and dust ($ΛCDM$). In this work we show that, if this is true for the background equations, this is not true for the perturbation equations. Hence, the mass spectrum predicted for both models may differ.

description: Die San Andreas-Verwerfung zwischen Valyermo und Wrightwood ist durch eine Hauptverwerfungslinie charakterisiert, die durch Verwerfungskliffe und -senken und tektonische Depressionen mit Alluvionen, Sumpfland, Torfmooren und Teichen gekennzeichnet sind, ferner durch versetzte und verstellte Abflußrinnen, Querriegel und verstellte Hügel, vertonte Zerrüttungszonen, Stufen, Quellen, Vegetationskontraste und durch von Erdbeben verstellte Bäume. Sekundäre Verwerfungslinien divergieren und konvergieren mit der Hauptverwerfungslinie; bezeichnend für sie sind lithologische Kontraste zu unmittelbar benachbarten Schichten, orientierte Täler und vertonte Zerrüttungszonen. Die relative Rechts-Horizontalverschiebung beträgt mindestens 20 m und ist wahrscheinlich zum Teil durch das Fort Tejon-Erdbeben von 1857 verursacht. Die Rechtsverschiebung von verstellten Abflußrinnen variiert zwischen 20 und einigen hundert Metern. Die Verteilung des Older Alluvium (Jungpleistozän?) deutet auf eine kumulative scheinbare Rechtsverschiebung von etwa 3,5 km hin.

We count primes in short intervals represented by the norm of a prime ideal of $K$ satisfying a small sector condition determined by Hecke characters. We also show that such primes are well-distributed in arithmetic progressions in the sense of Bombieri-Vinogradov. This extends previous work of Duke and Coleman.

Molecular-field-theory fits to magnetic susceptibilities of antiferromagnetic GdCu2Si2, CuO, LiCrO2, and alpha-CaCr2O4 single crystals below their Neel temperatures

subject: FOS: Physical sciences

description: A recently-developed molecular field theory (MFT) has been used to fit single-crystal magnetic susceptibility chi versus temperature T data below the respective antiferromagnetic ordering temperatures TN for a variety of collinear and coplanar noncollinear Heisenberg antiferromagnets. The spins in the system are assumed to interact by Heisenberg exchange and to be identical and crystallographically equivalent. The fitting parameters for chi(T) of collinear antiferromagnets are measurable quantities: the Weiss temperature theta_p in the Curie-Weiss law, TN, chi(TN), and the spin S. For coplanar noncollinear helix and cycloid structures, an additional fitting parameter is the turn angle between layers of ferromagnetically-aligned spins. Here MFT fits to anisotropic chi(T) data from the literature for single crystals of the collinear antiferromagnets GdCu2Si2 and CuO and the noncollinear antiferromagnets LiCr2As2 with a 120 degree cycloidal structure and alpha-CaCr2O4 with a 120 degree helical structure below their respective Neel temperatures are presented. The MFT fit to the anisotropic chi(T < TN) data for CuO is poor, whereas the fits to the data for GdCu2Si2, LiCrO2, and alpha-CaCr2O4 are quite good. The poor fit for CuO is attributed to the influence of strong quantum fluctuations associated with the small Cu spin and the quasi-one-dimensional magnetism that are not taken into account by the MFT. The magnetic contribution to the zero-field heat capacity of the collinear antiferromagnet GdNiGe3 at T < TN is also fitted by the MFT.

description: We estimate the Cronin effect in pA collisions at the CERN LHC and at RHIC, using a Glauber-Eikonal model of initial state multiparton interactions. For a correct determination of the initial parton flux, we upgrade the model cross section, taking carefully into account all kinematical constraints of each multi-parton interaction process. As compared with previous results, derived with approximate kinematics, we obtain a softer spectrum of produced partons, while improving the agreement of the model with the recent measurements of neutral pions production in d+Au collisions at sqrt(s)=200 AGeV.

description: GRB031203 was a very low apparent luminosity gamma-ray burst (GRB). It was also the first GRB with a dust-scattered X-ray halo. The observation of the halo allowed us to infer the presence of a large soft X-ray fluence in the total burst output. It has, however, also been claimed that GRB031203 was intrinsically sub-energetic, representative of a class of spectrally hard, low-energy bursts quite different from other GRBs. Reanalysis of the available data confirms our original finding that GRB031203 had a very large soft X-ray component, the time of which can be constrained to within a few minutes after the burst, implying that while GRB031203 did indeed have a very low apparent luminosity, it was also very soft. Notions propagated in the literature regarding the uncertainties in the determination of the soft X-ray fluence from the halo data and on the available constraints from the hard X-ray data are addressed: the properties of the scattering dust along the line of sight (grain sizes, precise location and the geometry) are determined directly from the high quality X-ray data so that there is little uncertainty about the scatterer; constraints on the X-ray lightcurve from the Integral spacecraft at the time of the soft X-ray blast are not complete because of a slew in the spacecraft pointing shortly after the burst. Claims that GRB031203 was intrinsically under-energetic and that it represents a deviation from the luminosity-peak energy relation do not appear to be substantiated by the data, regardless of whether the soft X-ray component is declared part of the prompt emission or the afterglow. We conclude that the difference between the soft and hard X-ray spectra from XMM-Newton and Integral indicate that a second soft pulse probably occurred in this burst as has been observed in other GRBs, notably GRB050502B.

description: We compute the electroweak corrections due to the light fermions to the production cross section $σ(g g \to H)$ and to the partial decay widths $Γ(H \to γγ)$ and $Γ(H \to g g)$. We present analytic results for these corrections that are expressed in terms of Generalized Harmonic Polylogarithms. We find that for the gluon fusion production cross section and for the decay width $Γ(H \to g g)$ the corrections are large in the Higgs mass region below 160 GeV where they reach up to 9% of the lowest order term. For the decay width $Γ(H \to γγ)$ the corrections for Higgs mass above 160 GeV can reach $-$10% of the lowest order term.

description: Bei der Kartierung für den Geologischen Atlas der Schweiz 1: 25000 in der Zentralschweiz und in den westlichen Glarner Alpen wurden viele Quartärstrukturen als Ansätze von Mittelmoränen erkannt. Mittelmoränen, gebildet aus zwei Seitenmoränen am Zusammenfluss zweier Gletscher, wurden in der Eiszeitliteratur bisher viel zu wenig beachtet. Als Obermoränen lassen sie sich meist bis ans Zungenende verfolgen. Im proximalen Bereich liefern Mittelmoränen Hinweise auf die Eishöhen. Im distalen Bereich sind viele bisher als Drumlin kartierte Bildungen als Mittelmoränen zu deuten. Übereinander gelegene Abfolgen zeigen, dass Mittelmoränen sich oft über mehrere Kaltzeiten an den selben Stellen eingestellt haben. Ebenso lassen sich in ihrer Lage schwer verständliche, isolierte Schotter-Vorkommen auf Hochflächen des Mittellandes als von epiglaziären Schmelzwässern verschwemmtes Schuttgut auf Grund gelaufener Mittelmoränen erklären. Bisher wurden solche meist in der Schweiz als Überreste von alten Schotterfluren, als Deckenschotter-Vorkommen, gedeutet. In diese zusammenhängende Flur hätten sich später die Täler sukzessive eingetieft, was jedoch nie belegt worden ist.

description: In modern applications of heterogeneous liquid-phase nanocatalysis, the catalysts (e.g., metal nanoparticles) need to be typically affixed to a colloidal carrier system for stability and easy handling. "Passive carriers" (e.g., simple polyelectrolytes) serve for a controlled synthesis of the nanoparticles and prevent coagulation during catalysis. Recently, however, hybrid conjugates of nanoparticles and synthetic thermosensitive polymers have been developed that enable to change the catalytic activity of the nanoparticles by external triggers. In particular, nanoparticles embedded in a stimuli-responsive network made from poly(N-isopropylacrylamide) (PNIPAM) have become the most-studied examples of such hybrids. It has been demonstrated that the permeability of the polymer network and thus the reactant flux can be switched and controlled by external stimuli. Such "active carriers" may thus be viewed as true nanoreactors that open up new design routes in nano-catalysis and elevate synthesis to create highly selective, programmable "colloidal enzymes". However, only a comprehensive understanding of these materials on all time and length scales can lead to a rational design of future, highly functional materials. Here we review the current state of the theoretical and multi-scale simulation approaches, aiming at a fundamental understanding of these nanoreactors. In particular, we summarize a theoretical approach for reaction rates of surface-catalyzed bimolecular reactions in responsive nanoreactors in terms of the key material parameters, the polymer shell permeability P and the reactant partition ratio K. We discuss recent computer simulation studies of both atomistic and coarse-grained polymer models in which these quantities have been characterized in some detail. We conclude with an outlook on selected open questions and future theoretical challenges in nanoreactor modeling.

description: Equipping visitors of a cultural site with a wearable device allows to easily collect information about their preferences which can be exploited to improve the fruition of cultural goods with augmented reality. Moreover, egocentric video can be processed using computer vision and machine learning to enable an automated analysis of visitors' behavior. The inferred information can be used both online to assist the visitor and offline to support the manager of the site. Despite the positive impact such technologies can have in cultural heritage, the topic is currently understudied due to the limited number of public datasets suitable to study the considered problems. To address this issue, in this paper we propose EGOcentric-Cultural Heritage (EGO-CH), the first dataset of egocentric videos for visitors' behavior understanding in cultural sites. The dataset has been collected in two cultural sites and includes more than $27$ hours of video acquired by $70$ subjects, with labels for $26$ environments and over $200$ different Points of Interest. A large subset of the dataset, consisting of $60$ videos, is associated with surveys filled out by real visitors. To encourage research on the topic, we propose $4$ challenging tasks (room-based localization, point of interest/object recognition, object retrieval and survey prediction) useful to understand visitors' behavior and report baseline results on the dataset.

description: The disruption of supplies during the Covid-19 crisis has led to shortages but has also shown the adaptability of some companies, which have succeeded in adapting their production chains quickly to produce goods experiencing shortages: hydroalcoholic gel, masks, and medical gowns. These productive jumps from product A to product B are feasible because of the know-how proximity between the two classes of products. The proximities were computed from the analysis of co-exports and resulted in the construction of the product space. Based on the product space, as well as the customer-supplier relationships resulting from the input-output matrices, we propose a recommender system for companies. The goal is to promote distributed manufacturing by recommending a list of local suppliers to each company. As there is not always a local supplier for a desired product class, we consider the proximity between products to identify, in the absence of a supplier, a substitute supplier able to adapt its production tools to provide the required product. Our experiments are based on French data, from which we build a graph of synergies illustrating the potential productive links between companies. Finally, we show that our approach offers new perspectives to determine the level of territories' industrial resilience considering potential productive jumps.

description: Im Illergletscher-Vorland, Bayern, ist das Mindelglazial (drittletzter Eiszeitkomplex des nördlichen Alpenvorlandes) am Grönenbacher Feld definiert. Die vorliegenden Geländebefunde zeigen, dass das Vorkommen stratigraphisch zweigeteilt ist und zu einer stratigraphischen Neubewertung zwingt. Die Untergliederung wird durch in zwei Höhenniveaus liegende glazifluviatile Schmelzwasserterrassen dokumentiert, die an der Wurzel des Grönenbacher Feldes in zwei glaziale Serien übergehen. Sie liegen im Süden des Feldes übereinander und werden von einem Verwitterungshorizont im Mühlbach-Tobel unterteilt. Er deutet auf einen eisfreien Zeitabschnitt mit Ausbildung eines Bodenhorizontes hin. Das ältere Terrassenniveau (Woringer Schotter) wird dem jüngsten Stadial der im Illergletscher-Vorland dreigeteilten Mindeleiszeit zugerechnet (Mindel 3). Die Existenz des Verwitterungshorizontes, morphologische und flussgeschichtliche Argumente sowie der Verwitterungszustand des jüngeren Schotters (Grönenbacher Schotter) legen nahe, dass dieser jünger als mindel-, aber älter als risszeitlich ist. Damit könnte er der Paareiszeit zuzurechnen sein, die nomenklatorisch eingeführt, jedoch bislang umstritten ist. In vorliegender Arbeit werden die Geländebefunde sowie die Folgerungen für die stratigraphische Zuordnung diskutiert.

title: Care staff perceptions of adults with profound learning disabilities: contents and processes
Creators: name: Kenny, Sarah
Publisher: name: The Open University
Year: 2000

description: Background and Aims:This research dissertation attempts to elicit care staff perceptions of clients with profound learning disabilities and the processes involved in these perceptions. There is little research in the area of staff perspectives in this field. Clinical psychologists working in this field often have extensive contact with staff regarding clients, and conflict regarding perception of clients can arise. It is suggested that for psychologists to gain some insight into how staff perceive clients and the processes involved would help to facilitate understanding of, and co-operation, with care staff.

Design and Participants: A qualitative design was employed as the study was seen as exploratory and was investigating the personal experiences and perspectives of participants. Participants were nine direct care staff who worked in a variety of service settings.

Measures: Each respondent completed a written free response description of a client of their choice. This was followed by a semi-structured interview that aimed to explore the processes involved in staff perceptions of clients.

Results: Written descriptions shared some factors in common with free response description within the general population. However, novel categories included communication issues, behavioural difficulties and the disability itself The interviews suggested that there were complex processes operating that made it difficult for respondents to acknowledge the disability and still feel positive about the clients and the work. There was also a marked change over time described by respondents in their perceptions of clients.

Implications: It is suggested care staff need a forum for acknowledging and exploring difficult feelings. Clinical psychologists are well placed to facilitate this but must also be aware of their own problems regarding acknowledging and coping with profound disability. Awareness of the issues might also help psychologists to work more sensitively and productively with staff.

description: Deep learning methods usually require a large amount of training data and lack interpretability. In this paper, we propose a novel knowledge distillation and model interpretation framework for medical image classification that jointly solves the above two issues. Specifically, to address the data-hungry issue, a small student model is learned with less data by distilling knowledge from a cumbersome pretrained teacher model. To interpret the teacher model and assist the learning of the student, an explainer module is introduced to highlight the regions of an input that are important for the predictions of the teacher model. Furthermore, the joint framework is trained by a principled way derived from the information-theoretic perspective. Our framework outperforms on the knowledge distillation and model interpretation tasks compared to state-of-the-art methods on a fundus dataset.

description: We describe theoretically the main characteristics of the steady state regime of a type II Optical Parametric Oscillator (OPO) containing a birefringent plate. In such a device the signal and idler waves are at the same time linearly coupled by the plate and nonlinearly coupled by the $χ^{(2)}$ crystal. This mixed coupling allows, in some well-defined range of the control parameters, a frequency degenerate operation as well as phase locking between the signal and idler modes. We describe here a complete model taking into account all possible effects in the system, \emph{i.e.} arbitrary rotation of the waveplate, non perfect phase matching, ring and linear cavities. This model is able to explain the detailed features of the experiments performed with this system.

description: Inertial measurement units are commonly used in a growing number of application fields to track or capture motions of kinematic chains, such as human limbs, exoskeletons or robotic actuators. A major challenge is the presence of magnetic disturbances that result in unreliable magnetometer readings. Recent research revealed that this problem can be overcome by exploitation of kinematic constraints. While typically each segment of the kinematic chain is equipped with an IMU, a novel approach called sparse inertial motion tracking aims at infering the complete motion states from measurements of a reduced set of sensors. In the present contribution, we combine the magnetometer-free and the sparse approach for real-time motion tracking of double-hinge joint systems with non-parallel joint axes. Analyzing the observability of the system, we find a condition which assures that the relative orientations between all segments are uniquely determined by a kinematic constraint, which contains only the gyroscope readings. Furthermore, we propose a moving-horizon estimator and validate it in a simulation study of three movements with different degrees of excitation. The results of this study confirm all theoretical conjectures and demonstrate that magnetometer-free sparse inertial real-time motion tracking is feasible under precise and simple excitation conditions.

description: We present an automated design procedure for the rapid realization of wideband millimeter-wave lens antennas. The design method is based upon the creation of a library of matched unit-cells which comprise wideband impedance matching sections on either side of a phase-delaying core section. The phase accumulation and impedance match of each unit-cell is characterized over frequency and incident angle. The lens is divided into rings, each of which is assigned an optimal unit-cell based on incident angle and required local phase correction given that the lens must collimate the incident wavefront. A unit-cell library for a given realizable permittivity range, lens thickness, and unit-cell stack-up can be used to design a wide variety of flat wideband lenses for various diameters, feed elements, and focal distances. A demonstration GRIN lens antenna is designed, fabricated, and measured in both far-field and near-field chambers. The antenna functions as intended from 14 GHz to 40 GHz and is therefore suitable for all proposed 5G MMW bands, Ku- and Ka-band fixed satellite services. The use of intrinsically matched unit-cells results in aperture efficiency ranging from 31% to 72% over the 2.9:1 bandwidth which is the highest aperture efficiency demonstrated across such a wide operating band.

description: Im Rahmen geomorphologischer Untersuchungen von Flussterrassen und ihren Deckschichten werden im mittleren Neckarraum drei neue Aufschlüsse beschrieben und die darin enthaltenen fossilen Molluskenfaunen vorgestellt. In zwei Fällen (Heilbronn-Böckingen und Obereisesheim) handelt es sich bei den fossilführenden Sedimenten um Sande, Kiese und Hochflutlehme, welche die vorletztkaltzeitlichen Schotter der 5-7 m-Terrasse i.S.v. Bibus (2002) abschließen. Die Molluskenfunde bestätigen, dass es sich im mittleren Neckarbecken bei Hochflutsedimenten auf der 5-7 m-Terrasse um warmzeitliche Bildungen handelt, welche in das Eem gestellt werden müssen. Die gleiche Höhenlage der Vorkommen belegt, dass es nach dem Eem im Heilbronner Raum zu keiner großräumigen Tektonik gekommen ist. In Bietigheim-Bissingen wurden Mittelterrassenschotter (Basis ca. 20 m über Enzniveau) sowie deren Deckschichten untersucht. Die überaus artenreiche Molluskenfauna mit Theodoxus serratiliniformis, Cochlostoma scalarinum saueri u.a. beweist, dass es sich dabei um ein Äquivalent derjenigen Schotter handelt, deren Molluskenfauna bereits 1914 von Geyer veröffentlicht wurde, und die seitdem zu den bedeutendsten Fundstellen mittelpleistozäner Mollusken in Deutschland zählt. Aufgrund der terrassenmorphologischen Situation sowie zusätzlicher Nachweise chronostratigraphisch aussagekräftiger Molluskenarten, war es erstmals möglich, eine genauere Altersbestimmung durchzuführen. Alle bisher vorliegenden Daten sprechen dafür, dass es sich bei den molluskenführenden Mittelterrassenschottern von Bietigheim-Bissingen um Bildungen der fünftletzten Warmzeit (OIS 13, Cromer IV i.S.v. Zagwijn 1989) handelt.

description: Zwischen den Angaben der C14-Datierungen und den Altersbestimmungen nach den Blei- und Helium-Methoden klafft in der Erdgeschichte eine Lücke, die durch andere geophysikalische und geochemische Methoden bisher nicht befriedigend geschlossen wird. Aufbauend auf relativen Datierungsversuchen im Quartär Westdeutschlands mit Hilfe der Fluormethode, wird in Kombination mit Ergebnissen der erstgenannten Methoden eine Kurve entwickelt, die eine absolute Datierung der Interglazialzeiten (pleistozänen Warmzeiten) gestattet. Vorbehaltlich in Aussicht gestellter Korrekturen würde aufgrund dieser Kurve das Alter des Eem-Interglazials auf 60 000 Jahre und älter, das des Holstein-Interglazials auf ca. 240 000 Jahre, das der Cromer-Warmzeit auf ca. 640 000 Jahre und das der Tegelen-Warmzeit auf 1 500 000 ± 300 000 Jahre anzusetzen sein.

description: In der Monte Cavallo-Gruppe fand Verf. in Stauseesedimenten fossile Holzstücke, für die die 14 C-Datierung ein Alter von 29 350 ± 460 Jahren vor 1950 n. Chr. ergab. Die schluffigen Ablagerungen, die in etwa 900 m, fast 80 m über dem heutigen Flußbett des T. Caltea aufgeschlossen sind, ruhen auf Schottern und werden von Moräne überlagert. Aufgrund seiner stratigraphischen Lage und seines 14C-datierten Alters kann das Holz (Picea abies bzw. Larix) einem zeitlichen Äquivalent des Paudorf-Interstadials zugeordnet werden. Dieser Fund von Großresten ermöglicht somit eine erste absolute Datierung des Paudorf-Interstadials für die Südalpen und Oberitalien.

description: We demonstrate that size fluctuations close to polymers critical point originate the non-Gaussian diffusion of their center of mass. Static universal exponents $\gamma$ and $\nu$ -- depending on the polymer topology, on the dimension of the embedding space, and on equilibrium phase -- concur to determine the potential divergency of a dynamic response, epitomized by the center of mass kurtosis. Prospects in experiments and stochastic modeling brought about by this result are briefly outlined.

description: Millisecond pulsars are neutron stars (NSs) that are thought to have been spun-up by mass accretion from a stellar companion. It is unknown whether there is a natural brake for this process, or if it continues until the centrifugal breakup limit is reached at submillisecond periods. Many NSs that are accreting from a companion exhibit thermonuclear X-ray bursts that last tens of seconds, caused by unstable nuclear burning on their surfaces. Millisecond brightness oscillations during bursts from ten NSs (as distinct from other rapid X-ray variability that is also observed) are thought to measure the stellar spin, but direct proof of a rotational origin has been lacking. Here, we report the detection of burst oscillations at the known spin frequency of an accreting millisecond pulsar, and we show that these oscillations always have the same rotational phase. This firmly establishes burst oscillations as nuclear-powered pulsations tracing the spin of accreting NSs, corroborating earlier evidence. The distribution of spin frequencies of the 11 nuclear-powered pulsars cuts off well below the breakup frequency for most NS models, supporting theoretical predictions that gravitational radiation losses can limit accretion torques in spinning up millisecond pulsars.

title: Distribution of potato cyst nematodes in England and Wales and the use of 1,3-dichloropropene for their control
Creators: name: Minnis, Stephen Thomas
Publisher: name: The Open University
Year: 2001

description: In the UK the most problematic pests of the potato crop are the potato cyst nematodes Globodera rostochiensis and G. pallida. A structured survey of potato growing land in England and Wales was undertaken to reassess their occurrence and distribution. PCN were present in 64% of sites sampled and of the populations found, 67% were G. pallida, 8% were G. rostochiensis and 25% contained both species. Just over 50% of the sites sampled had a rotation length of 1 in 5 or less and cultivars with partial resistance to G. pallidarepresented only 6% of the total number of plantings while those with resistance to G. rostochiensisrepresented 43%. The results show an increase in the incidence of PCN compared with previous surveys and confirm the perceived shift towards G. pallida as the predominant species.

Two field experiments were done to look at the integration of methods for the control of PCN and subsequent reduction in yield loss in situations of very high PCN levels. The first experiment assessed the use of 1,3-dichloropropene (1,3-D) with the granular nematicides aldicarb, oxamyl and fosthiazate when growing the susceptible cultivar Estima. The second experiment assessed the use of the resistant cultivar Sante with 1,3-D and oxamyl at full and half-rates. 1,3-D significantly advanced emergence, increased percentage ground cover, root invasion, yield, tuber numbers, and improved tuber size distribution. Nematode multiplication was significantly reduced by fumigation in the first experiment.

The use of 1,3-D for the control of weed seeds was assessed and the results show a reduction in germination of weed seeds in soil after fumigation. The use of 1,3-D for the control of Rhizoctonia solani was also assessed and a trend in reduction in R. solani was observed after fumigation although the differences were not statistically significant.
Glueballs and k-strings in SU(N) gauge theories : calculations with improved operators

description: We test a variety of blocking and smearing algorithms for constructing glueball and string wave-functionals, and find some with much improved overlaps onto the lightest states. We use these algorithms to obtain improved results on the tensions of k-strings in SU(4), SU(6), and SU(8) gauge theories. We emphasise the major systematic errors that still need to be controlled in calculations of heavier k-strings, and perform calculations in SU(4) on an anisotropic lattice in a bid to minimise one of these. All these results point to the k-string tensions lying part-way between the `MQCD' and `Casimir Scaling' conjectures, with the power in 1/N of the leading correction lying in [1,2]. We also obtain some evidence for the presence of quasi-stable strings in calculations that do not use sources, and observe some near-degeneracies between (excited) strings in different representations. We also calculate the lightest glueball masses for N=2, ...,8, and extrapolate to N=infinity, obtaining results compatible with earlier work. We show that the N=infinity factorisation of the Euclidean correlators that are used in such mass calculations does not make the masses any less calculable at large N.

description: We revisit the cosmological history in the presence of light moduli by including possible thermal effects in the scalar potential. The well known cosmological moduli problem regards initial energy stored in the moduli due to a misalignment from its final position during inflation. We show that finite temperature corrections to the scalar potential, in general, induce similar effects and these are likely to overcome the ones from the misalignment. This changes important parameters like the preferred window for the numbers of e-fold during inflation and the final reheating temperature in a model-dependent manner. The general implications are a longer late modulus dominated epoch and a larger final reheating temperature. We explore all the discussed elements in type-IIB superstring Large Volume Compactification with a Kähler inflationary scenario, where zero temperature results are known. An instability analysis, using a Floquet approach, is also performed for this explicit case finding strong indications of possible oscillon production around a nearly universal normalized critical temperature, where the Floquet exponents show a divergent behaviour.

Die Vertebratenfauna, insbesondere die zahlreichen Kleinsäuger und die Molluskenfauna, lassen den Übergang von der Rißeiszeit zum R/W-Interglazial erkennen. Dabei zeigt sich, daß sich der faunistische Übergang zur Warmzeit bereits in der Phase der Lößbildung andeutet.

description: Massive stars play an important role in the mechanical and chemical evolution of galaxies. Understanding the internal processes of these stars is vital to our understanding of their evolution and eventual end products. Deformations from spherical geometry are common for massive stars; however, the tools that are currently available for the study of these systems are almost exclusively one-dimensional. We present a new spectroscopic analysis tool tailored for massive stars that deviate from spherical symmetry. This code (entitled SPAMMS) is a spectroscopic patch model that takes the three-dimensional surface geometry of the system into account to produce spectral profiles at given phases and orientations. In using the Wilson-Devinney-like code PHOEBE in combination with the non local thermodynamic equilibrium (NLTE) radiative transfer code FASTWIND, we created a three-dimensional mesh that represents the surface geometry of our system and we assigned FASTWIND emergent intensity line profiles to each mesh triangle, which take the local parameters such as temperature, surface gravity, and radius into account. These line profiles were then integrated across the visible surface, where their flux contribution and radial velocity are taken into account, thus returning a final line profile for the visible surface of the system at a given phase. We demonstrate that SPAMMS can accurately reproduce the morphology of observed spectral line profiles for overcontact systems. Additionally, we show how line profiles of rapidly-rotating single stars differ when taking rotational distortion into account, and the effects that these can have on the determined parameters. Finally, we demonstrate the code's ability to reproduce the Rossiter-Mclaughlin and Struve-Sahade effects.
