Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Blazars are high-energy engines providing us natural laboratories to study particle acceleration, relativistic plasma processes, magnetic field dynamics, black hole physics. Key informations are provided by observations at high-energy (in particular by Fermi/LAT) and very-high energy (by Cherenkov telescopes). I give a short account of the current status of the field, with particular emphasis on the theoretical challenges connected to the observed ultra-fast variability events and to the emission of flat spectrum radio quasars in the very high energy band.

description: Green technologies are at the very core of endeavors to combine economic and environmental targets to achieve sustainable growth. In this article, we aim to determine the impact of green technology development on total factor productivity of European regions. Our paper contributes to the literature on technological change and regional growth in various ways. i) Our paper is, to the best of our knowledge, the first to assess the specific role of green technologies for regional growth on a broad empirical base. ii) We advance methodologically on the pertinent literature by explicitly accounting for cross-sectional dependence in our empirical approach. iii) By providing a simple theoretical framework, we directly link our results to implications of environmental policies for capital accumulation and composition dynamics, contributing to the ongoing debate revolving around the strong version of the Porter hypothesis. Our results, based on a sample of 270 European NUTS-2 regions over 25 years, imply that general technology development is mostly associated with positive economic returns, but our data is not supportive of positive economic returns to green technologies.

description: Cold metal forming belongs to the most important manufacturing processes for sheet metal mass products. To meet increasing requirements concerning part quality and economic efficiency, tool wear has to be minimized. Therefore, most of the forming processes are only feasible with lubricant application. Especially for processes with high tool load, such as blanking or embossing, adhesive wear is a key challenge due to early initiation and high wear rates. Despite the high significance and consequences, like a reduction of part quality and process reliability as well as an increasing risk of severe tool damage, wear-causing interactions are insufficiently understood. One known influencing factor is the temperature in the forming zone, which arises due to the dissipation of conducted forming work. Besides the direct impact on adhesive wear, this temperature rise leads to thermoelectric voltages and currents, whose influence on adhesive wear development has been neglected so far. For this reason, typical tool and sheet materials have been characterized for the first time with regard to their thermoelectric behavior, represented by the Seebeck coefficient. Together with experimental blanking and embossing investigations, basic correlations between process parameters, temperatures, sheet and tool materials, thermoelectric currents as well as adhesive wear could be derived. The findings obtained confirm a strong influence of the direction and strength of thermoelectric currents, which are determined by the difference between the Seebeck coefficients of tool and sheet material, on adhesive wear. Similar thermoelectric behavior of both materials in contact suppresses thermocurrents and resulted in an adhesive wear reduction of 74% during blanking. In addition, the external generation of a regulated current enables to influence thermoelectric currents in strength and direction. An external current adapted to the process reduced adhesive wear by 31%. In sum, two new methods of adhesive wear reduction, which are applicable in every metal manufacturing process, were investigated within this project. Furthermore, the knowledge gained improves the fundamental understanding of wear-causing interactions.
Spinozistische Feldmetaphysik und physikalisches Materieverständnis

Year: 2010
Subjects: subject: Metaphysics
subject: Early modern period
subject: Philosophy of Science
subject: 100

description: This paper contrasts Jonathan Bennett’s field metaphysical interpretation of Spinoza with field theoretic approaches from modern physics. Following on from the variety of examples given by Bennett and his followers, this discussion encompasses both classical as well as quantum field theories; in particular, different versions of geometrodynamics and the attempts by Einstein and others towards a unified field theory. This then leads to the question of whether a sustainable analogy between modern field physics and Spinoza’s metaphysics (and hence a Spinozian philosophy of nature) is possible at all. Such an analogy seems available, but — as the discussion will show — it is strongly dependent on the interpretation of Spinoza’s distinction between finite and infinite modes.

description: Al-rich aluminum borates were prepared by different synthesis routes using various Al/B ratios, characterized by diffraction methods, spectroscopy and prompt gamma activation analysis. The 11B NMR data show a small amount of BO4 species in all samples. The chemical analysis indicates a trend in the Al/B ratio instead of a fixed composition. Both methods indicate a solid solution Al5−xB1+xO9 where Al is substituted by B in the range of 1–3%. The structure of B-rich Al4B2O9 (C2/m, a=1488 pm, b=553 pm, c=1502 pm, ß=90.6°), was re-investigated by electron diffraction methods, showing that structural details vary within a crystallite. In most of the domains the atoms are orderly distributed, showing no signal for the postulated channel oxygen atom O5. The absence of O5 is supported by density functional theory calculations. Other domains show a probable disordered configuration of O5 and O10, indicated by diffuse scattering along the b direction.

description: This paper tests the hypothesis that distinctive feature classifiers anchored at phonetic landmarks can be transferred cross-lingually without loss of accuracy. Three consonant voicing classifiers were developed: (1) manually selected acoustic features anchored at a phonetic landmark, (2) MFCCs (either averaged across the segment or anchored at the landmark), and(3) acoustic features computed using a convolutional neural network (CNN). All detectors are trained on English data (TIMIT),and tested on English, Turkish, and Spanish (performance measured using F1 and accuracy). Experiments demonstrate that manual features outperform all MFCC classifiers, while CNNfeatures outperform both. MFCC-based classifiers suffer an F1reduction of 16% absolute when generalized from English to other languages. Manual features suffer only a 5% F1 reduction,and CNN features actually perform better in Turkish and Span-ish than in the training language, demonstrating that features capable of representing long-term spectral dynamics (CNN and landmark-based features) are able to generalize cross-lingually with little or no loss of accuracy

description: Zu den Schadstoffen, die bei der Verbrennung von Biomasse freigesetzt werden, gehören NOx CO, CO2, SO2, VOC und Feinstaub (PM), um nur einige zu nennen [2]. Einige der wichtigsten Umweltauswirkungen, wie photochemischer Smog und saurer Regen sowie Folgen für die menschliche Gesundheit, werden durch NOx verursacht [3,4]. Eine Möglichkeit zur Verringerung der NOx Emissionen ist die selektive katalytische Reduktion (SCR). Diese Katalysatoren werden in einer High-Dust-, Low-Dust-, oder Tail-End-Konfiguration installiert [5]. Die in der Biomasse enthaltenen Spurenstoffe wie Phosphor (P), Kalium (K) und Natrium (Na) [2] haben auf konventionelle Katalysatoren deaktivierenden Eigenschaften und verkürzen die Standzeiten [4]. Daraus ergeben sich besondere Herausforderung für die Entwicklung von Entstickungssystemen beim Einsatz von biogenen Reststoffen. In diesem Projekt mit der Bezeichnung DeNOx-DePM soll der Katalysator als Additiv direkt dem Rauchgas zugesetzt werden, so dass ein katalytisch aktiver Filterkuchen am Gewebefilter gebildet wird und der Katalysator nach seiner Deaktivierung zusammen mit dem Feinstaub entfernt werden kann.

description: We numerically propose a scheme for realizing an all-optical femtosecond soliton diode based on a tailored heterojunction Bragg grating, which is designed by two spatially asymmetric chirped cholesteric liquid crystals. Our simulations demonstrate that with the consideration of optical nonlinearity, not only the femtosecond diode effect with nonreciprocal transmission ratio up to 120 can be achieved, but also the optical pulse evolving into soliton which maintains its shape during propagation through the sample is observed. Further, the influence of pulse width and the carrier wavelength to the femtosecond diode effect is also discussed in detail. Our demonstrations might suggest a new direction for experimentally realizing the femtosecond soliton diode based on the cholesteric liquid crystals.

description: Educators do not have to be mere "Translators" as manufacturers of algorithms for teaching in the infosphere, but must modulate it for everyone's purposes. This work aims to validate the moments of transformation, through which, over the centuries, the mathematical sciences, with the help of philosophy, have promoted the Natural Language Generation to formal models. The starting hypothesis intends to corroborate an epistemological framework, which assigns logical-mathematical reasoning to mental processes following four models: Chomsky, who, with descriptive grammar marks a new model for rewriting languages; Gross, who, with the relationship between linguistics, computer science, and mathematics generates a relationship concerning a strongly transdisciplinary domain, in which linguistics realizes computer-based models and procedures; Silberzstein's Nooj system for processing, describing and analyzing INLG fixed sentences. The focal part of the research is the work of comparison that the team carried out to validate the development of languages according to the Transformational Analysis of Direct Transitive by M. Silberzstein and the lexicon-grammar; probabilistic calculus, according to the Probabilistic latent semantic Analysis.

description: Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energies and it also varies dramatically. The polarization of blazars is of interest for understanding the origin, confinement, and propagation of jets. However, even though numerous measurements have been performed, the mechanisms behind jet creation, composition and variability are still debated. We performed simultaneous gamma-ray and optical photopolarimetry observations of 45 blazars between Jul. 2008 and Dec. 2014 to investigate the mechanisms of variability and search for a basic relation between the several subclasses of blazars. We identify a correlation between the maximum degree of optical linear polarization and the gamma-ray luminosity or the ratio of gamma-ray to optical fluxes. Since the maximum polarization degree depends on the condition of the magnetic field (chaotic or ordered), this result implies a systematic difference in the intrinsic alignment of magnetic fields in pc-scale relativistic jets between different types blazars (FSRQs vs. BL Lacs), and consequently between different types of radio galaxies (FR Is vs. FR IIs).

An Unsteady Flowmeter for Pulsatile Flow

Publisher: name: University of Alberta Library
Year: 2022

This paper outlines the design of an unsteady flowmeter for ex-vivo heart perfusion applications. In order to determine the performance of a given heart, the flowrate in the system must be recorded. The proposed design is based on an orifice plate flowmeter comprising three pressure transducers and in which the flow measurement is obtained by numerically solving a modified version of the unsteady Bernoulli equation. As an intrinsic characteristic, pulsatile flows have acceleration and deceleration phases, so the flowmeter must account for these unsteady effects to produce accurate measurements. In addition to measuring laminar and turbulent bi-directional flows, the operational context also imposes several restrictions on the design, such as being disposable, low cost, easy handling and small in size. Three prototypes were experimentally tested by applying sinusoidal flows using a peristaltic pump at a frequency range of 15 - 30 Hz and then verified by applying physiological-like flow with a ventricular assist device (VAD) at a frequency of 1 Hz. The device was experimentally calibrated by means of a gravimetric procedure. The results showed that oscillatory flows can be measured with an accuracy of approximately 1% for the range from 1 to 2.5 L/min, while for lower flow rates (< 0.5 L/min) the accuracy was around 5%. It was found that the average discharge coefficient among the three manufactured flowmeters was Cd = 0.7119.

description: Die Idee zu der vorliegenden Studie über Arbeitsbedingungen und Interessenregulation in der New Economy ist auf dem Höhepunkt der Boom-Phase im Frühjahr 2000 entstanden. Zum damaligen Zeitpunkt (März 2000) notierte der NEMAX noch auf einem Höchststand von über 9500 Punkten. Kurz darauf setzte die Talfahrt am Neuen Markt ein – mit dem bekannten Ende. Als wir im Sommer 2001 mit der Akquise der Kooperationsunternehmen für den qualitativen Teil der Studie begannen, wurde auch unser Vorhaben von den Umbrüchen erfasst, denn eine große Zahl der Unternehmen, deren Profile wir kurz zuvor im Internet recherchiert hatten, war bereits vom Markt verschwunden oder sie befanden sich in laufenden Konkursverfahren. Zwei Monate später – 10 Unternehmen schienen gefunden – nahm das Vorhaben schließlich immer deutlichere Züge einer Obduktionsforschung an: Von den 10 Firmen die ihre Mitarbeit im Sommer zugesagt hatten, waren zwei in der Zwischenzeit „verstorben“, bei einem Unternehmen war die verantwortliche Personalchefin entlassen worden, bei einem anderen hatte die Geschäftsleitung gewechselt. Im weiteren Verlauf des Forschungsprojektes wurden wir dann immer wieder von den rasanten Veränderungen, denen die untersuchten Unternehmen und ihre Beschäftigten ausgesetzt waren (und sind), eingeholt und bekamen einen realistischen und ungemein spannenden Einblick in die Arbeitswelt der „internetworker“. Wir möchten allen Beteiligten in den Firmen für ihre Offenheit bei den Interviews sowie für die Mitarbeit und konstruktive Kritik im Verlaufe unseres Workshops im Juni 2003 herzlich danken. Sie haben dieses Projekt erst möglich gemacht und von ihnen handelt der nachfolgende Bericht.

description: In this paper, Samia Bano comments on Karin van Marle's keynote presentation at the Diversity and Legal Reasoning Workshop held at Queen Mary University of London on 23 November 2016, sponsored by the Centre for Research on Law, Equality and Diversity and the Centre for Law and Society in a Global Context. Bano argues that in order for debates on diversity and legal reasoning not to become overly abstract or theoretical and therefore remain outside the social and cultural practices in which they operate, it is important that a critical rearticulation and reflection on the question of diversity and legal reasoning engages critically with questions of ontology, agency and the production and reproduction of resistant knowledges. This kind of critical engagement requires also a critique of internal power relations and knowledge claims made within communities and groups.

description: We present an infinite family of formulas with reversal whose avoidability index is bounded between 4 and 5, and we show that several members of the family have avoidability index 5. This family is particularly interesting due to its size and the simple structure of its members. For each $k\in\{4,5\}$, there are several previously known avoidable formulas (without reversal) of avoidability index $k$, but they are small in number and they all have rather complex structure.

title: Remarks on Some Simple Variants of Random Context Grammars
Creators: name: Gazdag, Zsolt

description: It is known that the expressive power of random context grammars is the same with
or without the following restrictions: (1) in every rule either the permitting set or the
forbidding set is empty and the other one is a singleton and (2) each rule that rewrites
the same nonterminal symbol have the same permitting and forbidding sets. It is also
known that the permitting variants of these restricted random context grammars are
equivalent to permitting random context grammars. In this paper we show a similar
result concerning the forbidding case. We show that, when erasing rules are allowed,
the forbidding variants of these restricted random context grammars are equivalent to
forbidding random context grammars.
It is also known that forbidding random context grammars are weaker than the
computationally complete random context grammars. Thus, it is natural to ask how
many permitting symbols are required in a random context grammar to achieve computational
completeness. We show that every recursively enumerable language can
be generated by a random context grammar having restrictions similar to (1) and (2)
above and using only one permitting nonterminal symbol.

description: Ausgehend von diesen Fragen möchte ich in diesem Aufsatz ein Puzzle aus fünf Teilen zusammensetzen. Ich werde zunächst (1.) versuchen zu klären, was Technik selbst heute alles sein kann – und wie ihre Genese und Diffusion auf Prozesse des sozioöko-nomischen Wandels zurückwirkt. Daran anschließend werde ich (2.) verschiedene Va-rianten soziotechnischen Wandels voneinander unterscheiden und deren typische Charakteristika und Verlaufsformen skizzieren. In einer weiteren Vorabklärung nehme ich (3.) wesentliche soziale Träger des Wandels in den Blick: ihre Ausdifferenzierung, Handlungsorientierungen und Interaktionsmuster. Auf dieser Grundlage werde ich (4.) anhand der staatlichen Technologie- und Innovationspolitik herausarbeiten, über wel-che Einwirkungs- und Gestaltungsmöglichkeiten die Politik in der ‚dizzy atmosphere‘ außerordentlicher technologischer Dynamiken und unübersichtlicher sozialer Hand-lungsträgerschaften heute noch verfügt. Schließlich – darauf läuft alles hinaus – werde ich (5.) danach fragen, wie sich die technologie- und innovationspolitischen Gestal-tungsmöglichkeiten und -erfahrungen für die politische Mitgestaltung einer nachhaltig-keitsorientierten Technikentwicklung nutzen und weiterentwickeln lassen.

subject: 330

description: Vor diesem Hintergrund stehen im Zentrum dieses artec-papers klimawandelbezogene Veränderungen der Nachfrage und des Konsumverhaltens. Hierzu werden zunächst die Entwicklung der Umwelteinstellungen einerseits (Kap. 2) und die Preisentwicklung andererseits (Kap. 3) thematisiert. Hieran schließt ein Überblick über die Entwicklung der privaten Konsumausgaben an (Kap. 4). Auf dieser Basis wird der Forschungsbedarf zu den Wechselwirkungen dieser klimabezogenen Entwicklungen expliziert und Ausblick auf ein Projekt gegeben, das sich im Rahmen des vom Bundesministerium für Bildung und Forschung (BMBF) geförderten Verbundprojektes „NordWest 2050“ mit diesen Fragen beschäftigt (Kap. 5). Das Erkenntnisinteresse richtet sich auf die Wahrnehmung und die Anpassungsstrategien privater Konsumentinnen und Konsumenten im Kontext von Klimawandel und Preisveränderungen. Die Ausführungen dienen als Ausgangspunkt für die Bestimmung der Folgen, die sich aus den Veränderungen auf der Nachfrageseite für die regionalen Angebotsstrukturen allgemein wie auch speziell für nachhaltige Produktalternativen und Dienstleistungen ergeben. Die Ausführungen fokussieren insbesondere auf die Konsumbereiche Energie, Mobilität und Ernährung.
Effects of backreaction and exponential nonlinear electrodynamics on the holographic superconductors

description: We analytically study the properties of a $(2+1)$-dimensional $s$-wave holographic superconductor in the presence of exponential nonlinear electrodynamics. We consider the case in which the scalar and gauge fields back react on the background metric. Employing the analytical Sturm-Liouville method, we find that in the black hole background, the nonlinear electrodynamics correction will affect the properties of the holographic superconductors. We find that with increasing both backreaction and nonlinear parameters, the scalar hair condensation on the boundary will develop more difficult. We obtain the relation connecting the critical temperature with the charge density. Our analytical results support that, even in the presence of the nonlinear electrodynamics and backreaction, the phase transition for the holographic superconductor still belongs to the second order and the critical exponent of the system always takes the mean-field value $1/2$.

The Development and Validation of a Self-Efficacy Tool for People over 60 with Venous Leg Ulceration

description: Venous leg ulceration has a high recurrence rate. Patients with healed or frequently recurring venous ulceration are required to perform self-care behaviours to prevent recurrence or promote healing, but many find these difficult to perform. Bandura’s self-efficacy theory is a widely used and robust behaviour change model and underpins many interventions designed to promote self-care in a variety of chronic conditions. By identifying areas where patients may experience difficulty in performing self-care, interventions can be developed to strengthen their self-efficacy beliefs in performing these activities successfully. There are currently a variety of self-efficacy scales available to measure self-efficacy in a variety of conditions; but not a disease-specific scale for use with venous ulcer patients. The aim of this study, therefore, was to develop a disease-specific, patient-focused self-efficacy scale for patients with healed venous leg ulceration. Phase 1 consisted of a qualitative design and used focus group methodology to generate an item pool for potential inclusion into the scale from the patients’ perspective. In phase 2, factor analysis using equamax orthogonal rotation methods was used to reduce the items from 60 to 30, resulting in 5 major domains: general self-care; daily self-care tasks; normal living; developing expertise and avoiding trauma. Preliminary reliability studies indicated that the developed scale, VeLUSET© has good internal consistency, with an overall Cronbach alpha of .929 and a strong test-re-test reliability. Furthermore, correlation with the General Self-Efficacy Scale demonstrated a strong positive relationship between the two scales. These results indicate that the VeLUSET©, although still in the early validation stages, is a reliable instrument to measure venous leg ulcer patients’ self-efficacy in performing self-care tasks within clinical practice. The development of this disease-specific tool has now filled a gap in the research on managing patients with healed venous leg ulceration.

description: There is a growing effort in creating chiral transport of sound waves. However, most approaches so far are confined to the macroscopic scale. Here, we propose a new approach suitable to the nanoscale which is based on pseudomagnetic fields. These fields are the analogon for sound of the pseudomagnetic field for electrons in strained graphene. In our proposal, they are created by simple geometrical modifications of an existing and experimentally proven phononic crystal design, the snowflake crystal. This platform is robust, scalable, and well-suited for a variety of excitation and readout mechanisms, among them optomechanical approaches.
