description: Inspired by the ideas from topological field theory it is possible to rewrite the supersymmetric charges of certain classes of extended supersymmetric Yang--Mills (SYM) theories in such a way that they are compatible with the discretization on a Euclidean spacetime lattice. Such theories are known as maximally twisted SYM theories. In this review we discuss the construction and some applications of such classes of theories. The one-loop perturbative renormalization of the four-dimensional lattice ${\cal N}=4$ SYM is discussed in particular. The lattice theories constructed using twisted approach play an important role in investigating the thermal phases of strongly coupled SYM theories and also the thermodynamic properties of their dual gravitational theories.

description: It is widely known that cooking contributes particulate matter (PM) to outdoor and indoor air. TO research the morphology and chemical composition of PM10 and PM2.5 in cooking fumes, four Chinese restaurants with distinct cooking styles were sampled. A Zeiss Merlin Compact (FE-SEM) with EDS system was used to determine the morphology and chemical composition of individual PM. The results show six types of particles with different morphologies: rectangular, flocculent, flat, irregular, spheroidal and spherical, and they are primarily Ca-rich, C-rich and Si-rich particles. The most abundant PM was Ca-rich particles with rectangular shape, thus, Chinese style cooking may be an important source of rectangular Ca-S particles The amount of these particles was affected by the cooking style and method: water-based cooking methods emitted more rectangular Ca-S particles, C-rich particles with spherical shapes were abundant in cooking fumes from oil-based cooking methods, and the spheroidal particles in cooking fumes are closely associated with roasting.

description: Im Vergleich zum vergangenen Jahr schwächt sich die deutsche Konjunktur merklich ab. Die Bestellungen aus dem Ausland sinken und die heimischen Unternehmen halten sich mit Investitionen zurück. Die Kapazitäten bleiben jedoch stark ausgelastet – auch weil im kommenden Jahr die Regierung die Einkommen der privaten Haushalte anschiebt. Aber vor allem steigen die Einkommen wegen der guten Lage am Arbeitsmarkt spürbar: Die Arbeitslosenquote sinkt auf 5,2 Prozent in diesem Jahr und auf 4,9 Prozent im kommenden. Die deutsche Wirtschaft wächst alles in allem in diesem Jahr um 1,9 Prozent und im Jahr 2019 um 1,7 Prozent.

description: Precision toxicology evaluates the toxicity of certain substances by isolating a small group of cells with a typical phenotype of interest followed by a single cell sequencing-based analysis. In this in vitro attempt, ochratoxin A (OTA), a typical mycotoxin and food contaminant, is found to induce G0/G1 phase cell cycle arrest in human renal proximal tubular HKC cells at a concentration of 20 μM after a 24h-treatment. A small number of G0/G1 phase HKC cells are evaluated in both the presence and absence of OTA. These cells are sorted with a flow cytometer and subjected to mRNA and DNA methylation sequencing using Smart-Seq2 and single-cell reduced-representation bisulfite sequencing (scRRBS) technology, respectively. Integrated analysis of the transcriptome and methylome profiles reveals that OTA causes abnormal expression of the essential genes that regulate G1/S phase transition, act as signal transductors in G1 DNA damage checkpoints, and associate with the anaphase-promoting complex/cyclosome. The alteration of their DNA methylation status is a significant underlying epigenetic mechanism. Furthermore, Notch signaling and Ras/MAPK/CREB pathways are found to be suppressed by OTA. This attempt at precision toxicology paves the way for a deeper understanding of OTA toxicity and provides an innovative strategy to researchers in the toxicology and pharmacology field.

description: Die politischen Rahmenbedingungen der weltwirtschaftlichen Entwicklung sind derzeit durch vielfache Unsicherheiten geprägt; dies lastet insbesondere auf der Investitionstätigkeit und bremst die globale Konjunktur. Das DIW Berlin reduziert seine Prognose für das laufende und das kommende Jahr daher leicht auf 4,1 Prozent beziehungsweise 3,9 Prozent. Der globale Aufschwung scheint aber weithin intakt. In den entwickelten Volkswirtschaften stützt vor allem die gute Lage am Arbeitsmarkt den Konsum. Für die USA ist vor dem Hintergrund von finanzpolitischen Impulsen zudem mit höheren Wachstumsraten als zu Jahresbeginn zu rechnen. Für den Euroraum haben sich die Aussichten hingegen eingetrübt. Auch viele Schwellenländer stehen stärker unter Druck – neben hausgemachten Problemen vor allem wegen der Dollarstärke, die mit der gestiegenen Unsicherheit und einer global weniger expansiv ausgerichteten Geldpolitik einhergeht. Im weiteren Verlauf dürften der Anstieg des weltweiten Zinsniveaus, erste Arbeitskräfteengpässe in den entwickelten Volkswirtschaften und eine weitere graduelle Verlangsamung des Wachstums in China die Weltkonjunktur weiter entschleunigen. Risiken für die Fortsetzung des globalen Aufschwungs gehen vor allem von protektionistischen Bestrebungen der USA sowie politischen Unsicherheiten im Euroraum aus.

Biomechanics of cervical spine and spinal cord injury under combined axial compression and lateral bending loading
Creators: name: Van Toen, Carolyn Yvonne
Publisher: name: University of British Columbia
Year: 2014

description: Cervical spine and spinal cord injuries are significant health concerns. Although lateral forces are present during real-world head-first impacts, there is a lack of information about combined lateral bending moments with axial compression. The general aim of this research was to evaluate the effects of lateral bending in dynamic axial compression of the cervical spine on kinetics, kinematics, canal occlusions, and injuries of the cervical spine and this required the development of novel loading and measurement apparatus. We experienced technical challenges in experimentally producing lateral bending moments requiring novel loading methods. Also, as acoustic emission (AE) signals could provide more objective estimates of the timing of injuries produced experimentally, these techniques were developed for use in the spine. In Study 1, techniques were developed to measure the time of injury of isolated spinal components using AE signals. Injuries to human cadaver vertebral bodies resulted in AE signals with higher amplitudes and frequencies than those from ligamentum flavum specimens. Study 2 presented a theoretical and experimental evaluation of the effects of test configuration on bending moments during eccentric axial compression. Design recommendations were provided that allowed us to apply appropriate bending moments in the subsequent studies. In Studies 3, 4, and 5 dynamic axial compression forces with lateral eccentricities were applied to human cadaver cervical spine segments and AE signals were used to detect the time of injury. High lateral eccentricities resulted in lower peak axial forces, inferior displacements, and canal occlusions and greater peak ipsilateral bending moments, bending rotations, displacements, and spinal flexibilities in lateral bending and axial rotation compared to low eccentricity impacts. Also, low and high lateral eccentricities produced primarily hard and soft tissue injuries, respectively. In this three-vertebra model, AE signals from injuries to endplates and/or vertebral bodies had higher amplitudes and frequencies than those from injuries to the intertransverse ligament and/or facet capsule. The effects of lateral bending in dynamic axial compression on injury mechanisms of the cervical spine and the injury detection techniques demonstrated in this thesis may potentially assist in the development and improvement of injury prevention and treatment strategies.

description: The numerous phenomenological equations used in the study of the behaviour of single-domain magnetic nanoparticles are described and some issues clarified by means of qualitative comparison. To enable a quantitative \textit{application} of the model based on the Debye (exponential) relaxation and the torque driving the Larmor precession, we present analytical solutions for the steady states in presence of circularly and linearly polarized AC magnetic fields. Using the exact analytical solutions, we can confirm the insight that underlies Rosensweig's introduction of the "chord" susceptibility for an approximate calculation of the losses. As an important consequence, it can also explain experiments, where power dissipation for both fields were found to be identical in "root mean square" sense. We also find that this approximation provides satisfactory numerical accuracy only up to magnetic fields for which the argument of the Langevin function reaches the value 2.8.

description: We consider a decentralized detection problem in a power-constrained wireless sensor networks (WSNs), in which a number of sensor nodes collaborate to detect the presence of a deterministic vector signal. The signal to be detected is assumed known \emph{a priori}. Given a constraint on the total amount of transmit power, we investigate the optimal linear precoding design for each sensor node. More specifically, in order to achieve the best detection performance, shall sensor nodes transmit their raw data to the fusion center (FC), or transmit compressed versions of their original data? The optimal power allocation among sensors is studied as well. Also, assuming a fixed total transmit power, we examine how the detection performance behaves with the number of sensors in the network. A new concept "detection outage" is proposed to quantify the reliability of the overall detection system. Finally, decentralized detection with unknown signals is studied. Numerical results are conducted to corroborate our theoretical analysis and to illustrate the performance of the proposed algorithm.

description: This meta-analysis examined communication outcomes in single-case design studies of augmentative and alternative communication (AAC) interventions and their relationship to participant characteristics. Variables addressed included chronological age, pre-intervention communication mode, productive repertoire, and pre-intervention imitation skills. Investigators identified 114 single-case design studies that implemented AAC interventions with school-aged individuals with autism spectrum disorder and/or intellectual disability. Two complementary effect size indices, Tau(AB) and the log response ratio, were applied to synthesize findings. Both indices showed positive effects on average, but also exhibited a high degree of heterogeneity. Moderator analyses detected few differences in effectiveness when comparing across diagnoses, age, the number and type of communication modes, participant’s productive repertoires, and imitation skills to intervention.

Effective theory of fractional topological insulators in two spatial dimensions
Creators: name: Nikolic, Predrag
Publisher: name: arXiv
Year: 2012
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Electrons subjected to a strong spin-orbit coupling in two spatial dimensions could form fractional incompressible quantum liquids without violating the time-reversal symmetry. Here we construct a Lagrangian description of such fractional topological insulators by combining the available experimental information on potential host materials and the fundamental principles of quantum field theory. This Lagrangian is a Landau-Ginzburg theory of spinor fields, enhanced by a topological term that implements a state-dependent fractional statistics of excitations whenever both particles and vortices are incompressible. The spin-orbit coupling is captured by an external static SU(2) gauge field. The presence of spin conservation or emergent U(1) symmetries would reduce the topological term to the Chern-Simons effective theory tailored to the ensuing quantum Hall state. However, the Rashba spin-orbit coupling in solid-state materials does not conserve spin. We predict that it can nevertheless produce incompressible quantum liquids with topological order but without a quantized Hall conductivity. We discuss two examples of such liquids whose description requires a generalization of the Chern-Simons theory. One is an Abelian Laughlin-like state, while the other has a new kind of non-Abelian many-body entanglement. Their quasiparticles exhibit fractional spin-dependent exchange statistics, and have fractional quantum numbers derived from the electron's charge and spin according to their transformations under time-reversal. In addition to conventional phases of matter, the proposed topological Lagrangian can capture a broad class of hierarchical Abelian and non-Abelian topological states, involving particles with arbitrary spin or general emergent SU(N) charges.

Dabei wird insbesondere über die Schaffung eines europäischen Stabilisierungsmechanismus diskutiert. Diese Studie befasst sich mit den zu erwartenden makroökonomischen Auswirkungen eines Stabilisierungsfonds, dessen konjunkturelle Folgen in einem Gleichgewichtsmodell untersucht werden. Es zeigt sich, dass der Stabilisierungsfonds konjunkturelle Schwankungen reduziert und somit einen Mechanismus darstellt, um den gesamten Währungsraum in Zukunft krisenfester zu machen. Dabei ist zu beachten, dass ein Stabilisierungsfonds politisch eher durchsetzbar sein dürfte als die Verlagerung von nationalen Kompetenzen an ein neu zu schaffendes europäisches Finanzministerium. Zudem sollte das moralische Risiko im Hinblick auf das Verhalten einzelner Länder bei der Ausgestaltung des Stabilisierungsfonds berücksichtigt werden. So sollte parallel zur Einführung eines europäischen Stabilisierungsfonds die Einhaltung festgelegter Fiskalregeln wirksam durchgesetzt werden.

Intersection of Yang-Mills Theory with Gauge Description of General Relativity
Creators: name: Kober, Martin
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: An intersection of Yang-Mills theory with the gauge description of general relativity is considered. This intersection has its origin in a generalized algebra, where the generators of the SO(3,1) group as gauge group of general relativity and the generators of a SU(N) group as gauge group of Yang-Mills theory are not separated anymore but are related by fulfilling nontrivial commutation relations with each other. Because of the Coleman Mandula theorem this algebra cannot be postulated as Lie algebra. As consequence, extended gauge transformations as well as an extended expression for the field strength tensor is obtained, which contains a term consisting of products of the Yang Mills connection and the connection of general relativity. Accordingly a new gauge invariant action incorporating the additional term of the generalized field strength tensor is built, which depends of course on the corresponding tensor determining the additional intersection commutation relations. This means that the theory describes a decisively modified interaction structure between the Yang-Mills gauge field and the gravitational field leading to a violation of the equivalence principle.

description: We investigate the formation of the first stars at the end of the cosmic dark ages with a suite of three-dimensional, moving mesh simulations that directly resolve the collapse of the gas beyond the formation of the first protostar at the centre of a dark matter minihalo. The simulations cover more than 25 orders of magnitude in density and have a maximum spatial resolution of 0.05 R_sun, which extends well below the radius of individual protostars and captures their interaction with the surrounding gas. In analogy to previous studies that employed sink particles, we find that the Keplerian disc around the primary protostar fragments into a number of secondary protostars, which is facilitated by H2 collisional dissociation cooling and collision-induced emission. The further evolution of the protostellar system is characterized by strong gravitational torques that transfer angular momentum between the secondary protostars formed in the disc and the surrounding gas. This leads to the migration of about half of the secondary protostars to the centre of the cloud in a free-fall time, where they merge with the primary protostar and enhance its growth to about five times the mass of the second most massive protostar. By the same token, a fraction of the protostars obtain angular momentum from other protostars via N-body interactions and migrate to higher orbits. On average, only every third protostar survives until the end of the simulation. However, the number of protostars present at any given time increases monotonically, suggesting that the system will continue to grow beyond the limited period of time simulated here.

description: Kinder, die auf ein Gymnasium gehen und Eltern mit einem niedrigen Bildungsniveau haben, fallen im Laufe ihrer Schulzeit leistungsmäßig immer weiter zurück. Das gilt insbesondere dann, wenn sie in der fünften Klasse in den Fächern Mathematik und Deutsch noch EinserschülerInnen waren. Diese Studie, die auf Basis des Nationalen Bildungspanels (NEPS) als eine der ersten den Schulerfolg von Kindern während der gesamten Pflichtschulzeit von der ersten bis zur neunten Klasse unter die Lupe nimmt, zeigt, wie wichtig der elterliche Bildungshintergrund für die Schulnoten der Kinder ist. Schon in der Grundschule gibt es deutliche Unterschiede in den sprachlichen und mathematischen Fähigkeiten nach dem Elternhaus. Dies spiegelt sich später auch in der Aufteilung auf die verschiedenen Schulformen der Sekundarstufe wider. Während die Noten in der Realschule über die Zeit relativ konstant bleiben, schneiden an Gymnasien die ohnehin schon wenigen Kinder aus Elternhäusern mit niedrigem Bildungsniveau über die Zeit deutlichschlechter ab. Neben einer gezielteren Förderung im frühkindlichen Alter sollten diese Kinder vor allem in der Schule stärker unterstützt werden.

description: We study the nuclear symmetry energy S(rho) and related quantities of nuclear physics and nuclear astrophysics predicted generically by relativistic mean-field (RMF) and Skyrme-Hartree-Fock (SHF) models. We establish a simple prescription for preparing equivalent RMF and SHF parametrizations starting from a minimal set of empirical constraints on symmetric nuclear matter, nuclear binding energy and charge radii, enforcing equivalence of their Lorenz effective masses, and then using the pure neutron matter (PNM) equation of state (EoS) obtained from ab-initio calculations to optimize the pure isovector parameters in the RMF and SHF models. We find the resulting RMF and SHF parametrizations give broadly consistent predictions of the symmetry energy J and its slope parameter L at saturation density within a tight range of

On the fractional metric dimension of graphs
Creators: name: Feng, Min

Year: 2011
Subjects: subject: Combinatorics (math.CO)

description: In [S. Arumugam, V. Mathew and J. Shen, On fractional metric dimension of graphs, preprint], Arumugam et al. studied the fractional metric dimension of the cartesian product of two graphs, and proposed four open problems. In this paper, we determine the fractional metric dimension of vertex-transitive graphs, in particular, the fractional metric dimension of a vertex-transitive distance-regular graph is expressed in terms of its intersection numbers. As an application, we calculate the fractional metric dimension of Hamming graphs and Johnson graphs, respectively. Moreover, we give an inequality for metric dimension and fractional metric dimension of an arbitrary graph, and determine all graphs when the equality holds. Finally, we establish bounds on the fractional metric dimension of the cartesian product of graphs. As a result, we completely solve the four open problems.

Simulation of BSDEs by Wiener chaos expansion
Creators: name: Briand, Philippe
name: Labart, Céline
Publisher: name: arXiv
Year: 2012
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We present an algorithm to solve BSDEs based on Wiener chaos expansion and Picard's iterations. We get a forward scheme where the conditional expectations are easily computed thanks to chaos decomposition formulas. We use the Malliavin derivative to compute $Z$. Concerning the error, we derive explicit bounds with respect to the number of chaos and the discretization time step. We also present numerical experiments. We obtain very encouraging results in terms of speed and accuracy.

description: Kleinere Klassen in der Grundschule führen zu besseren Leistungen in den Fächern Deutsch und Mathematik. Außerdem senken sie die Wahrscheinlichkeit, eine Klasse wiederholen zu müssen. Dies zeigt die vorliegende Analyse der Testresultate von mehr als 38.000 SchülerInnen, die Daten der landesweiten Orientierungsarbeiten im Saarland auswertet. Das Ergebnis widerspricht auf den ersten Blick bisherigen Studien für Deutschland, die mehrheitlich keine signifikanten Klassengrößeneffekte finden konnten. In der vorliegenden Studie wird jedoch ein weiterentwickeltes Untersuchungsdesign verwendet. Die Analyse zeigt, dass ein Reduzieren der Klassengröße vor allem in größeren Klassen mit mindestens etwa 20 SchülerInnen effektiv ist. Insofern könnte es sinnvoll sein, die Bildung kleinerer Klassenverbünde zu fördern, um das Leistungsniveau von GrundschülerInnen anzuheben. Dies trifft nicht auf kleinere Klassen zu: Bis zu einer Grenze von etwa 20 SchülerInnen können Klassen sogar vergrößert werden, ohne dass es zu Leistungseinbußen in den Fächern Deutsch und Mathematik kommt

Equivariant Iwasawa theory and non-abelian Stark-type conjectures
Creators: name: Nickel, Andreas
Publisher: name: arXiv
Year: 2011
Subjects: subject: Number Theory (math.NT)

subject: 11R23, 11R42

description: We discuss three different formulations of the equivariant Iwasawa main conjecture attached to an extension K/k of totally real fields with Galois group G, where k is a number field and G is a p-adic Lie group of dimension 1 for an odd prime p. All these formulations are equivalent and hold if Iwasawa's μ-invariant vanishes. Under mild hypotheses, we use this to prove non-abelian generalizations of Brumer's conjecture, the Brumer-Stark conjecture and a strong version of the Coates-Sinnott conjecture provided that μ= 0.

description: Zwischen 1991 und 2015 sind die verfügbaren bedarfsgewichteten Einkommen der Personen in privaten Haushalten in Deutschland real im Durchschnitt um 15 Prozent gestiegen. Der größte Teil der Bevölkerung hat von diesen realen Einkommenszuwächsen profitiert, die Gruppen am unteren Ende der Einkommensverteilung allerdings nicht. Die Ungleichheit sowohl der Markt- als auch der verfügbaren bedarfsgewichteten Haushaltseinkommen verbleibt auf einem hohen Niveau. Das zeigt die vorliegende Studie auf Basis von Daten der Längsschnittstudie Sozio-oekonomisches Panel (SOEP). Die Armutsrisikoquote erreichte im Jahr 2015 16,8 Prozent im Vergleich zu rund elf Prozent Mitte der 1990er Jahre, wobei die Armutsrisikoquote im Jahr 2015 bei der Bevölkerung ohne Migrationshintergrund 13 Prozent betrug und bei Personen mit direktem Migrationshintergrund mit 29 Prozent mehr als doppelt so hoch war. Die Zunahme der Armutsrisikoquote lässt sich auch dadurch erklären, dass es einen höheren Anteil an Personen mit Migrationshintergrund gibt. Differenziert man nach dem Wohnstatus, kann für Eigentümerhaushalte eine konstant niedrige Armutsrisikoquote berichtet werden, während Mieterhaushalte einem deutlich gestiegenen Armutsrisiko ausgesetzt sind.
