description: By the first principles calculations based on the van der Waals density functional theory, we study the crystal structures and electronic properties of La-doped phenanthrene. Two stable atomic geometries of La$_1$phenanthrene are obtained by relaxation of atomic positions from various initial structures. The structure-\uppercase\expandafter{\romannumeral1} is a metal with two energy bands crossing the Fermi level, while the structure-\uppercase\expandafter{\romannumeral2} displays a semiconducting state with an energy gap of 0.15 eV, which has an energy gain of 0.42 eV per unit cell compared to the structure-\uppercase\expandafter{\romannumeral1}. The most striking feature of La$_1$phenanthrene is that La $5d$ electrons make a significant contribution to the total density of state (DOS) around the Fermi level, which is distinct from potassium doped phenanthrene and picene. Our findings provide an important foundation for the understanding of superconductivity in La-doped phenanthrene.

description: The metabolic capabilities and regulatory networks of bacteria have been optimized by evolution in response to selective pressures present in each species' native ecological niche. In a new environment, however, the same bacteria may grow poorly due to regulatory constraints or biochemical deficiencies. Adaptation to such conditions can proceed through the acquisition of new cellular functionality due to gain of function mutations or via modulation of cellular networks. Using selection experiments on transposon-mutagenized libraries of bacteria, we illustrate that even under conditions of extreme nutrient limitation, substantial adaptation can be achieved solely through loss of function mutations, which rewire the metabolism of the cell without gain of enzymatic or sensory function. A systematic analysis of similar experiments under more than 100 conditions reveals that adaptive loss of function mutations exist for many environmental challenges. Drawing on a wealth of examples from published articles, we detail the range of mechanisms through which loss-of-function mutations can generate such beneficial regulatory changes, without the need for rare, specific mutations to fine-tune enzymatic activities or network connections. The high rate at which loss-of-function mutations occur suggests that null mutations play an underappreciated role in the early stages of adaption of bacterial populations to new environments.

description: Am 20. bis 22. Juni 2008 fand im Arbeitnehmerzentrum Königswinter ein Workshop über die Literatur und soziale Situation der Dalits („Kastenlosen“) und Adivasis („Stammesbevölkerung“) in Indien statt. Etwa 400 Millionen Menschen gehören diesen Gruppen an. In der traditionellen indischen Gesellschaft bildeten die Dalits und Adivasis die untersten gesellschaftlichen Gruppen. Sie wurden auf vielfältige Weise diskriminiert. Heute gibt es in Indien viele Gesetze, die das Ziel haben, ihre Lage zu verbessern. Dennoch ist der Alltag Lage der meisten Dalits und Adivasis auch heute noch von Armut und Ausbeutung geprägt.

description: Boson sampling solves a classically intractable problem by sampling from a probability distribution given by matrix permanents. We propose a scalable implementation of Boson sampling using local transverse phonon modes of trapped ions to encode the Bosons. The proposed scheme allows deterministic preparation and high-efficiency readout of the Bosons in the Fock states and universal mode mixing. With the state-of-the-art trapped ion technology, it is feasible to realize Boson sampling with tens of Bosons by this scheme, which would outperform the most powerful classical computers and constitute an effective disproof of the famous extended Church-Turing thesis.

description: The phenomena of particle mixing and flavor oscillations in elementary particle physics can be addressed by the point of view of quantum information theory, and described in terms of multi-mode entanglement of single-particle states. In this paper we show that such a description can be extended to the domain of quantum field theory, where we uncover a fine structure of quantum correlations associated with multi-mode, multi-particle entanglement. By means of an entanglement measure based on the linear entropies associated with all the possible bipartitions, we analyze the entanglement in the states of flavor neutrinos and anti-neutrinos. Remarkably, we show that the entanglement is connected with experimentally measurable quantities, i.e. the variances of the lepton numbers and charges.

description: In this work, events in which a single top quark is produced in association with a Z-boson are investigated. Particular focus is on final states in which two leptons originate from the Z boson and the top quark decays hadronically. The analysis uses data collected with the Compact Muon Solenoid (CMS) detector between 2016 and 2018, corresponding to an integrated luminosity of 137 fb$^-$$^1$; data are produced from proton-proton collisions at the Large Hadron Collider (LHC), with a center of mass energy equal to 13 TeV. The discrimination between signal and backgrounds is optimized by testing different methods for the event reconstruction and with the implementation of a Deep Neural Network (DNN). In the last part of the analysis, a statistical fit is performed to the DNN output for the signal extraction, reaching an expected significance of the $\it tZq$ signal overbackground of 2.4o.

description: iDataCool is an HPC architecture jointly developed by the University of Regensburg and the IBM Research and Development Lab Böblingen. It is based on IBM's iDataPlex platform, whose air-cooling solution was replaced by a custom water-cooling solution that allows for cooling water temperatures of 70C/158F. The system is coupled to an adsorption chiller by InvenSor that operates efficiently at these temperatures. Thus a significant portion of the energy spent on HPC can be recovered in the form of chilled water, which can then be used to cool other parts of the computing center. We describe the architecture of iDataCool and present benchmarks of the cooling performance and the energy (reuse) efficiency.

description: Analytical solutions are constructed for an assembly of any finite number of bubbles in steady motion in a Hele-Shaw channel. The solutions are given in the form of a conformal mapping from a bounded multiply connected circular domain to the flow region exterior to the bubbles. The mapping is written as the sum of two analytic functions---corresponding to the complex potentials in the laboratory and co-moving frames---that map the circular domain onto respective degenerate polygonal domains. These functions are obtained using the generalised Schwarz-Christoffel formula for multiply connected domains in terms of the Schottky-Klein prime function. Our solutions are very general in that no symmetry assumption concerning the geometrical disposition of the bubbles is made. Several examples for various bubble configurations are discussed.

description: High-order finite difference methods are efficient, easy to program, scales well in multiple dimensions and can be modified locally for various reasons (such as shock treatment for example). The main drawback have been the complicated and sometimes even mysterious stability treatment at boundaries and interfaces required for a stable scheme. The research on summation-by-parts operators and weak boundary conditions during the last 20 years have removed this drawback and now reached a mature state. It is now possible to construct stable and high order accurate multi-block finite difference schemes in a systematic building-block-like manner. In this paper we will review this development, point out the main contributions and speculate about the next lines of research in this area.

description: We demonstrate the organometallic hexahapto complexation of chromium with graphene, graphite and carbon nanotubes. All of these extended periodic pi-electron systems exhibit some degree of reactivity toward the reagents CrCO)6 and (eta6-benzene)Cr(CO)3, and we are able to demonstrate the formation of (eta6-rene)Cr(CO)3 or (eta6-arene)2Cr, where arene = single-walled carbon nanotubes (SWNT), exfoliated graphene (XG), epitaxial graphene (EG) and highly-oriented pyrolytic graphite (HOPG). We find that the SWNTs are the least reactive presumably as a result of the effect of curvature on the formation of the hexahapto bond; in the case of HOPG, (eta6-HOPG)Cr(CO)3 was isolated while the exfoliated graphene samples were found to give both (eta6-graphene)2Cr, and (eta6-graphene)Cr(CO)3 structures. We report simple and efficient routes for the mild decomplexation of the graphene-chromium complexes which appears to restore the original pristine graphene state. This study represents the first example of the use of graphene as a ligand and is expected to expand the scope of graphene chemistry in connection with the application of this material in organometallic catalysis.

Optimal sparse volatility matrix estimation for high-dimensional Itô processes with measurement errors

description: Stochastic processes are often used to model complex scientific problems in fields ranging from biology and finance to engineering and physical science. This paper investigates rate-optimal estimation of the volatility matrix of a high-dimensional Itô process observed with measurement errors at discrete time points. The minimax rate of convergence is established for estimating sparse volatility matrices. By combining the multi-scale and threshold approaches we construct a volatility matrix estimator to achieve the optimal convergence rate. The minimax lower bound is derived by considering a subclass of Itô processes for which the minimax lower bound is obtained through a novel equivalent model of covariance matrix estimation for independent but nonidentically distributed observations and through a delicate construction of the least favorable parameters. In addition, a simulation study was conducted to test the finite sample performance of the optimal estimator, and the simulation results were found to support the established asymptotic theory.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We explore the validity of the generalized second law (GSL) of thermodynamics in flat FRW universe with apparent horizon and event horizon as the boundary. We found that in a universe with holographic Ricci dark energy and dark matter, interacting with each other, the GSL is satisfied at the apparent horizon and partially satisfied at the event horizon under thermal equilibrium conditions. We also analyses the GSL under non-equilibrium conditions and shows that the fulfillment of GSL at the apparent horizon implies that the temperature of the dark energy is greater than that of the horizon. Thus there occurs a flow of dark energy towards the apparent horizon. As a result the entropy of the dark energy decreases and that of horizon increases. This is verified by finding the evolution of the dark energy entropy and horizon entropy in a dark energy dominated universe under non-equilibrium conditions.

description: Work package 6 of the COVINFORM project focuses on community-level impacts of COVID-19 and multi-level policy responses. This deliverable outlines the empirical research to be conducted on this topic, under the remit of Task 6.2. The deliverable begins with an overview of the COVINFORM project objectives and WP6 objectives, followed by a summary of the findings of the desk research conducted in T6.1 on COVID-19 impacts and responses in the project’s sub-national research sites. While both impacts and policy responses differed greatly between sites, common factors could be identified: namely, the relevance of local socio-ecological system parameters; the participation of numerous actors; and the transnational relevance of key good practices, such as proactive coordination between government, established NGOs, and grassroots initiatives. Based on the findings of T6.1 and the theoretical work conducted within WP3, 4, and 5, the deliverable goes on to establish a theoretical framework for research on COVID-19 impacts and policy responses within the context of “community”. Drawing on public health and socio-ecological systems scholarship, the deliverable establishes a disaggregated definition of “community”, synthesises this definition with the socio-ecological systems framework developed in COVINFORM D3.1, and derives a set of research questions from this definition. Target populations and research methods are then identified, based upon the research questions. Within the WP, the populations to be studied are civil society organisation representatives on the one hand, and residents of the target sub-national research sites on the other. Both populations will be studied using qualitative methods. Specifically, variations on the problem-centred interview (PCI) will be used. The deliverable concludes with specifications on recruiting and data analysis, as well as annexes outlining details of the research procedure and presenting drafts of the data collection instruments.

Creation and abrupt decay of a quasi-stationary dark soliton in a polariton condensate

description: We predict the existence of a self-localized solution in a nonresonantly pumped exciton-polariton condensate. The solution has a shape resembling the well-known hyperbolic tangent profile of the dark soliton, but exhibits several distinct features. We find that it performs small oscillations, which are transformed into 'soliton explosions' at lower pumping intensities. Moreover, after hundreds or thousands of picoseconds of apparently stable evolution the soliton decays abruptly, which is explained by the acceleration instability found previously in the Bekki-Nozaki hole solutions of the complex Ginzburg-Landau equation. We show that the soliton can be formed spontaneously from a small seed in the polariton field or by using spatial modulation of the pumping profile.

description: In this paper we show that spherically symmetric BEC dark matter halos, with the $\sin r/r$ density profile, that accurately fit galactic rotation curves and represent a potential solution to the cusp-core problem are unstable. We do this by introducing back the density profiles into the fully time-dependent Gross-Pitaevskii-Poisson system of equations. Using numerical methods to track the evolution of the system, we found that these galactic halos lose mass at an approximate rate of half of its mass in a time scale of dozens of Myr. We consider this time scale is enough as to consider these halos are unstable and unlikely to be formed. We provide some arguments to show that this behavior is general and discuss some other drawbacks of the model that restrict its viability.

description: This paper presents the DYON simulations of the plasma burn-through phase at Joint European Torus (JET) with the ITER-like wall. The main purpose of the study is to validate the simulations with the ITER-like wall, made of beryllium. Without impurities, the burn-through process of a pure deuterium plasma is described using DYON simulations, and the criterion for deuterium burn-through is derived analytically. The plasma burn-through with impurities are simulated using wall-sputtering models in the DYON code, which are modified for the ITER-like wall. The wall-sputtering models and the validation against JET data are presented. The impact of the assumed plasma parameters in DYON simulations are discussed by means of parameter scans. As a result, the operation space of prefill gas pressure and toroidal electric field for plasma burn-through in JET is compared to the Townsend avalanche criterion.

description: Diese Arbeit geht der Frage nach, unter welchen Voraussetzungen spätbeginnender Lateinunterricht ab Klasse 9 stattfindet und wie die sich hieraus ergebenden lehrgangsspezifischen Chancen und Schwierigkeiten für die Konzeption von Lateinunterricht genutzt werden können. Als Ausgangspunkt der Untersuchung wird eine Schule in Berlin als Fallbeispiel vorgestellt, an der sich der spätbeginnende Lateinunterricht mit seinen Vor- und Nachteilen in der praktischen Umsetzung darstellen lässt. Die sich anschließende theoretische Charakterisierung der Lehr- und Lernvoraussetzungen des Lehrgangs zeigt in den Kategorien Alter, Fremdsprachenkenntnisse und Lernmotivation die großen Unterschiede zum Frühbeginn auf, woraus sich nicht nur die Notwendigkeit für ein eigenes Konzept ergibt, sondern auch erste Implikationen für die Gestaltung dieses Lateinlehrgangs abgeleitet werden können. Ausgehend davon wird ein eigenes Konzept für den Spätbeginn entwickelt, das dem Prinzip der "Kulturellen Mehrsprachigkeit" in der Multivalenz des Faches - Sprache, Text und Kultur - folgt.
description: This thesis addresses the question of how the circumstances of teaching Latin to older students differ from Latin for young pupils and how those different conditions require a new and more suitable concept of Latin teaching. Starting with a case study of Latin at a school in Berlin, where Latin is taught from Year 9 onwards, the main advantages and disadvantages of such a Latin course are observed from a practical point of view. In the following theoretical characterisation of learning conditions, it is shown how teaching and learning Latin works differently in this type of course with regard to age, knowledge of other foreign languages and motivation. Therefore, a specific concept that complies with those preconditions is very much needed. From these special circumstances, implications for a suitable design of a Latin course for older students can be drawn. With regard to these specific requirements, a new concept is developed, which follows a guiding principle of "cultural multilingualism" in every aspect of Latin teaching, i.e. language, text and culture.

description: The Lagrangian description of mechanical systems and the Legendre Transformation (considered as a passage from the Lagrangian to the Hamiltonian formulation of the dynamics) for point-like objects, for which the infinitesimal configuration space is TM, is based on the existence of canonical symplectic isomorphisms of double vector bundles T*TM, T*TM, and TT*M. We show that there exist an analogous picture in the dynamics of objects for which the configuration space is the vector bundle of n-vectors, if we make use of certain graded bundle structures of degree n, i.e. objects generalizing vector bundles (for which n=1). For instance, the role of TT*M is played in our approach by the vector bundle of n-vectors on the bundle of n-covectors, which is canonically a graded bundle of degree n over the bundle of n-vectors. Dynamics of strings and the Plateau problem in statics are particular cases of this framework.

description: We present Spitzer observations at 3.6 and 4.5um of the supernova SN2011dh (PTF11eon) in M51 from 18 days to 625 days after explosion. The mid-infrared emission peaks at 24 days after explosion at a few times 10^7 Lsun, and decays more slowly than the visible-light bolometric luminosity. The infrared color temperature cools for the first 90 days and then is constant. Simple numerical models of a thermal echo can qualitatively reproduce the early behavior. At late times, the mid-IR light curve cannot be explained by a simple thermal echo model, suggesting additional dust heating or line emission mechanisms. We also propose that thermal echoes can serve as effective probes to uncover supernovae in heavily obscured environments, and speculate that under the right conditions, integrating the early epoch of the mid-infrared light curve may constrain the total energy in the shock breakout flash.

description: Die Augen der Welt waren im Dezember 2007 auf die UN-Klimakonferenz in Bali gerichtet, die mit einer 24-stündigen Verlängerung in einem dramatischen Schlussakt endete. Im allgemeinen Trubel ging dabei das Abschlussstatement des indischen Delegierten unter, das deutlich macht, wie ernst Indien die Herausforderung durch den Klimawandel inzwischen zu nehmen bereit ist. Auch aus indischer Sicht hat jetzt die Zeit der ernsthaften Verhandlungen für ein neues internationales Klimaabkommen begonnen: „Der Weg nach Bali war im Prinzip stark, der von Bali ausgehende Weg muss aber viel stärker sein. Wir müssen Fortschritte machen auf dem Weg nach Polen und Dänemark und darüber hinaus, um nichts weniger als unsere zukünftigen Generationen zu retten. Und daher ist es nicht eine Frage, zu was Sie sich verpflichten oder ich mich verpflichte. Es ist eine Frage, zu was wir uns gemeinsam verpflichten, um diese Herausforderung zu bewältigen.“ In Polen wird im Dezember 2008 die nächste große UN-Klimakonferenz stattfinden. Im Dezember 2009 in Kopenhagen soll ein neues UN-Klimaabkommen verabschiedet werden, so der in Bali beschlossene Verhandlungsfahrplan. Die Länder Südasiens, allen voran Indien, werden eine wichtige Rolle in diesem Prozess spielen. Die sich aus der Klimawissenschaft ergebende Messlatte für einen ambitionierten Umgang mit dem Klimawandel liegt hoch.

description: Objectives:

While global measures of cardiovascular (CV) risk are used to guide prevention and treatment decisions, these estimates fail to account for the considerable interindividual variability in pre-clinical risk status. This study investigated heterogeneity in CV risk factor profiles and its association with demographic, genetic, and cognitive variables.

Methods:

A latent profile analysis was applied to data from 727 recently postmenopausal women enrolled in the Kronos Early Estrogen Prevention Study (KEEPS). Women were cognitively healthy, within three years of their last menstrual period, and free of current or past CV disease. Education level, apolipoprotein E ε4 allele (APOE4), ethnicity, and age were modeled as predictors of latent class membership. The association between class membership, characterizing CV risk profiles, and performance on five cognitive factors was examined. A supervised random forest algorithm with a 10-fold cross-validation estimator was used to test accuracy of CV risk classification.

Results:

The best-fitting model generated two distinct phenotypic classes of CV risk 62% of women were “low-risk” and 38% “high-risk”. Women classified as low-risk outperformed high-risk women on language and mental flexibility tasks (p = 0.008) and a global measure of cognition (p = 0.029). Women with a college degree or above were more likely to be in the low-risk class (OR = 1.595, p = 0.044). Older age and a Hispanic ethnicity increased the probability of being at high-risk (OR = 1.140, p = 0.002; OR = 2.622, p = 0.012; respectively). The prevalence rate of APOE-ε4 was higher in the high-risk class compared with rates in the low-risk class.

Conclusion:

Among recently menopausal women, significant heterogeneity in CV risk is associated with education level, age, ethnicity, and genetic indicators. The model-based latent classes were also associated with cognitive function. These differences may point to phenotypes for CV disease risk. Evaluating the evolution of phenotypes could in turn clarify preclinical disease, and screening and preventive strategies.
