title: Archäologie, Volkskunde und die Sepulkralkultur der Neuzeit: eine praxissoziologische Perspektive
Creators: name: Lippok, Juliane
Publisher: name: datalino
Year: 2017

description: Eine Möglichkeit, den dynamischen Wandel in der Neuzeit (1500–1800) zu erfassen, ist die Erforschung der Sepulkralkultur. Forschungsgeschichtlich haben sich zuerst die Europäische Ethnologie und später die Neuzeitarchäologie mit der materiellen Kultur der Neuzeit beschäftigt. Dennoch ist die gegenwärtige Situation durch eine mangelnde Zusammenarbeit beider Disziplinen und die Verzerrung des Forschungsfeldes durch veraltete Forschungsprämissen gekennzeichnet. Der Grund dafür ist in der Geschichte der beiden Fächer zu suchen. Die Frage, die sich heute stellt, ist, wie der so zwischen den Fächern entstandene Graben überbrückt und eine gemeinsame, umfassendere Forschungspraxis etabliert werden kann. Als Lösung schlage ich eine praxissoziologische Perspektive als Forschungshaltung vor. Das hat zwei Effekte. Zum einen wird ein Instrumentarium für gemeinsame Forschungen der Europäischen Ethnologie und der Neuzeitarchäologie bereitgestellt und zum anderen wird die ständige Reflexion der Forschungspraxis ermöglicht. Daraus resultiert eine differenziertere Erforschung der Neuzeit.
description: The Early Modern period (1500–1800) was a time of dynamic changes. One way to explore these changes is the investigation of post-medieval burial practices. From an historical perspective, post-medieval material culture first became the subject of folklore studies, later of post-medieval archaeology. However, currently the relationship between both disciplines is characterized by a lack of cooperation and outdated research premises. This situation results from each discipline’s own history. One of the current problems is how to bridge the gap between the disciplines that emerged from these developments, in order to enable new joint, high-standard research projects. I am suggesting a perspective rooted in sociological concepts of practice, which I consider a viable solution to this problem. The proposed approach will have two effects: first, it will provide an instrument for joint research endeavours; second, it will allow for a constant reflection of established research practices. This will result in improved, more comprehensive, and more adequate research strategies towards the Early Modern Period.

title: On Ripples - A Boundary Layer-Theoretical Definition
Creators: name: Zanke, Ulrich
name: Roland, Aron
Publisher: name: MDPI
Year: 2022

description: Once the first initial ripples have developed, they form according to the actual flow forces and sediment properties. In this paper, a semianalytical approach to determine the length of the developed ripples is presented. The theory assumes initial disturbances at the bed surface and corresponding flow separations resulting from an individual respective boundary layer. What causes the initial rhythmic perturbations is not the subject of this paper. Based on boundary layer theory, this approach explains a possible physical background for the existence and length of developed ripples in cohesion-free sediments. At the same time, the approach provides a distinction from dunes: ripples are sand waves affected by a viscous sublayer, and dunes are sand waves where this is not the case. Applications to Earth, Mars, and Titan are shown.

description: We consider generalizations of the entropic accelerating universe recently proposed in Ref. [4,5] and show that their background equations can be made equivalent to a model with a dark energy component with constant parameter of state $w_{X} = -1 + 2\, γ/3$, where $γ$ is related to the coefficients of the new terms in the Friedman equations. After discussing all the Friedman equations for an arbitrary $γ$, we show how to recover the standard scalings for dust and radiation. The acoustic scale $\ell_A$, related to the peak positions in the pattern of the angular power spectrum of the Cosmic Microwave Background anisotropies, is also computed and yields the stringent bound $|γ|\ll 1$. We then argue that future data might be able to distinguish this model from pure $Λ$CDM (corresponding to $γ=0$).

description: We present a technique which allows us to solve the Random Phase Approximation equations with finite-range interactions and treats the continuum part of the excitation spectrum without approximations. The interaction used in the Hartree-Fock calculations to generate the single particle basis is also used in the Continuum Random Phase Approximation calculations. We present results for the electric dipole and quadrupole excitations in the $^{16}$O, $^{22}$O, $^{24}$O, $^{40}$Ca, $^{48}$Ca and $^{52}$Ca nuclei. We compare our results with those of the traditional discrete Random Phase Approximation, with the continuum mean-field results and with the results obtained by a phenomenological approach. We study the relevance of the continuum, of the residual interaction and of the self-consistency. We also compare our results with the available total photoabsorption cross section data. We compare our photoabsorption cross section in $^4$He with that obtained by a calculation which uses a microscopic interaction.

description: Driving phobia is prevalent in injured individuals following motor vehicle crashes (MVCs). The evidence for virtual reality (VR) based psychological treatments for driving phobia is unknown. This systematic review synthesized the available evidence on the effectiveness, feasibility, and user experience of psychological treatments for driving phobia using VR. Three databases (PsycINFO, SCOPUS, and PubMed) were searched. Eligibility criteria included adults with clinical or sub-clinical levels of driving phobia manifesting as part of an anxiety disorder or post-traumatic stress disorder (PTSD). Primary outcomes were driving-related anxiety/fear or avoidance, PTSD symptoms and driving frequency/intensity, as well as treatment feasibility including recruitment, treatment completion and retention rates, user experience and immersion/presence in the VR program. Secondary outcomes were other health outcomes (e.g., depression) and VR technological features. The 14 included studies were of low methodological quality. Clinical and methodological heterogeneity prevented quantitative pooling of data. The evidence provided in this review is limited by trials with small sample sizes, and lack of diagnostic clarity, controlled designs, and long-term assessment. The evidence did suggest that VR-based psychological interventions could be feasible and acceptable in this population. For VR-based psychological interventions to be recommended for driving phobia, more high-quality trials are needed. Implications for rehabilitationVirtual reality (VR) based psychological treatments may be feasible and acceptable to patients with driving phobia.There is potential to increase accessibility to psychological therapies in patients with driving phobia following motor vehicle crashes through the use of digital psychiatry such as VR.

description: It is well known that Kasner-type cosmologies provide a useful framework for analyzing the three-dimensional anisotropic expansion because of the simplification of the anisotropic dynamics. In this paper relativistic multi-fluid Kasner-type scenarios are studied. We first consider the general case of a superposition of two ideal cosmic fluids, as well as the particular cases of non-interacting and interacting ones, by introducing a phenomenological coupling function $q(t)$. For two-fluid cosmological scenarios there exist only cosmological scaling solutions, while for three-fluid configurations there exist not only cosmological scaling ones, but also more general solutions. In the case of triply interacting cosmic fluids we can have energy transfer from two fluids to a third one, or energy transfer from one cosmic fluid to the other two. It is shown that by requiring the positivity of energy densities there always is a matter component which violates the dominant energy condition in this kind of anisotropic cosmological scenarios.

Entanglement Measures for Quasi-Two-Dimensional Fractional Quantum Hall States

description: We theoretically examine entanglement in fractional quantum hall states, explicitly taking into account and emphasizing the quasi-two-dimensional nature of experimental quantum Hall systems. In particular, we study the entanglement entropy and the entanglement spectrum as a function of the finite layer thickness $d$ of the quasi-two-dimensional system for a number of filling fractions $ν$ in the lowest and the second Landau levels: $ν$ = 1/3, 7/3, 1/2, and 5/2. We observe that the entanglement measures are dependent on which Landau level the electrons fractionally occupy, and find that filling factions 1/3 and 7/3, which are considered to be Laughlin states, weaken with $d$ in the lowest Landau level ($ν$=1/3) and strengthen with $d$ in the second Landau level ($ν$=7/3). For the enigmatic even-denominator $ν=5/2$ state, we find that entanglement in the ground state is consistent with that of the non-Abelian Moore-Read Pfaffian state at an optimal thickness $d$. We also find that the single-layer $ν= 1/2$ system is not a fractional quantum Hall state consistent with the experimental observation. In general, our theoretical findings based on entanglement considerations are completely consistent with the results based on wavefunction overlap calculations.

description: We propose computing bus devices that enable quantum information to be coherently transferred between topological and conventional qubits. We describe a concrete realization of such a topological quantum bus acting between a topological qubit in a Majorana wire network and a conventional semiconductor double quantum dot qubit. Specifically, this device measures the joint (fermion) parity of these two different qubits by using the Aharonov-Casher effect in conjunction with an ancilliary superconducting flux qubit that facilitates the measurement. Such a parity measurement, together with the ability to apply Hadamard gates to the two qubits, allows one to produce states in which the topological and conventional qubits are maximally entangled and to teleport quantum states between the topological and conventional quantum systems.

On a property of the Vesica Piscis

description: Vesica Piscis is a figure generated intersecting two circles having the same radius and such that the center of each circle lies on the exterior circumference of the other circle. The origin of the Vesica Piscis is ancient and unknown and this symbol has been present in all the ages up to nowadays. It has been proved that if two segments are traced joining particular points of the Vesica Piscis, these segments form a cross and their ratio is equal to the square root of three.
 One segment joins the two intersecting points of the two circumferences and the other segment joins the two intersecting points between the segment joining the two centers with the exterior circumferences themselves. In this article, we prove that the converse is also true: if we consider two intersecting circles and the aforementioned segments such that their ratio is equal to the square root of three, then the two circles form a Vesica Piscis. We prove this results through two alternative proofs. The first proof uses Euclidean geometry and the second proof uses analytic geometry.
Analysis of hybrid quasi-two-level converter based HVDC transmission system

Publisher: name: University of British Columbia

description: Voltage Source Converters (VSC) are universally utilized in the areas of power generation, conversion and transmission systems in different forms and high voltage rating of VSC becomes necessarily required for the High Voltage direct current (HVDC) which is admitted as a critical factor to the anticipation of constructing a high-capacity transmission system. Modular Multilevel Converter (MMC) makes it possible to realize a VSC topology with high voltage level and to avoid drawbacks, e.g. it processes high scalability and modularity for higher voltage and increases converter efficiency. Mathematical analysis of conventional HB-MMC is provided in Chapter 2, which lays foundation for the newly proposed topology. Basic controlling methods are demonstrated in Chapter 2. However, there are also some drawbacks for HB-MMC operation. Firstly, HB-MMC is vulnerable when it comes to DC-side faults. Secondly, the submodule losses are higher than thyristor based HVDC technology, leading to higher operating cost. Additionally, the submodule capacitance needs to be reduced in order to enable a smaller footprint. Based on the concept of Quasi-Two-Level Converter proposed for DC/DC converter application, Hybrid Q2LC is proposed for AC/DC converter application in this thesis. The contributions of the proposed topology include the reduction of switching and conduction losses, decreasing d_v/d_t stress for the AC transformer and loads. Additionally, third-order harmonic voltage injection technique is realized to limit the voltage range of AC chain-link which works as active filters to attenuate high-order harmonics. When the DC pole-to-pole fault takes place, normal and protection branches of AC chain-link are available to provide sufficient reverse blocking voltage to mitigate AC surging current. Besides, submodule capacitance of the main converter part can be further reduced, which is beneficial for the converter system to operate with high compactness and low losses. Simulation results of the proposed hybrid Q2LC with AC chain-link topology are provided in Chapter 4 based on MATLAB Simulink including both dynamic performances under normal and DC pole-to-pole fault operations. Comparisons of losses among different converter types are made. Basic parameters of the mentioned topologies are analyzed. In the last chapter, contribution summary and future works are illustrated respectively.

description: Spinal cord injury (SCI) has lifelong implications requiring treatment for outcomes including respiratory function, voice, pain, mood, and gait, among others. Music therapy (MT) and music-based interventions may be useful in the treatment of several outcomes. This review describes the use of MT and music-based interventions in individuals with SCI for rehabilitation and health and highlights future research priorities. MEDLINE, Embase, PsycInfo, CINAHL, RILM, Music Periodicals and Music Index were searched. Search terms included: SCI and music. Studies of cohorts with SCI using music interventions and descriptions of adapted instruments or development of MT programs were included. Abstracts and full texts were reviewed in duplicate. Data were extracted according to clinical outcomes. A structured synthesis was performed. Forty-three studies were included. Research in the field includes quantitative, qualitative and mixed-methods studies. Group singing and an individual songwriting program for self-concept were the most studied interventions. Outcomes varied; mood outcomes were most common. While qualitative data support the use of MT and music-based interventions in this population for a wide variety of outcomes, randomized controlled trials are needed. There is a lack of research on the use of individual MT in this population.

description: The definition of natural modes for confined structures is one of the central problems in physics, as in nuclear physics, astrophysics, etc. The main problem is due to the boundary conditions, when they are such to push out the problem from the class of Sturm-Liouville. This occurs when boundary conditions imply the presence of eigen-values, as for example when a scatterer excited from the outside gives rise to a transmitted and reflected field. An open cavity with an external or internal excitation represents a "non-canonical" problem, in the sense of a Sturm-Liouville's problem, due to the fact that cavity modes couple themselves with external modes. This problem is crucial when one intends to study light-matter interaction effects as absorption, spontaneous emission, stimulated emission, as they occur in micro-cavities.

description: Nodules are specific structure on legume roots, where the reduction of N2 gas to ammonia takes place. Nitrogen fixation is an enzymatic process, associated with symbiotic nitrogen-fixing bacteria (rhizobia). Nodulation is a complex process, genetically controlled by both partners of the symbiotic relationship as well as by the environment through its influence on the activity of each partner and on the interaction itself. Nodules collection is a very important procedure for isolation of effective rhizobia and it is affected by the growth state of legumes. Nodules are collected either directly from field-grown legumes or indirectly from soil collected from legume rhizosphere using a trap host grown under controlled greenhouse conditions

description: The adsorption behaviour of linear poly(oxyethylene) alkyl ether (CnEOm) is best described by a reorientation model. Based on a complete set of experimental data, including the adsorption kinetics, the equilibrium surface tension isotherm and the surface dilational visco-elasticity, the thermodynamic and kinetic adsorption parameters for some CnEOm at the water/air interface were determined. For the study, six CnEOm surfactants were selected (n = 10, 12 and 14 and m = 4, 5 and 8) and were studied by bubble profile analysis and maximum bubble pressure tensiometry. A refined theoretical model based on a reorientation-adsorption model combined with a diffusion-controlled adsorption kinetics and exchange of matter allowed us to calculate the surface layer composition by adsorbing molecules in different orientations. It turns out that at larger surface coverage, the adsorption rate decreases, i.e., the apparent diffusion coefficients are smaller. This deceleration can be explained by the transition of molecules adsorbed in a state of larger molar surface area into a state with smaller molar surface area.

description: Based on a four-layered self-doped $t-J$ type model and the slave-boson mean-field approach, we study theoretically the superconductivity in the electron-doped and hole-doped layers. The neighbor layers are coupled through both the single electron interlayer hopping and pair tunneling effect. The superconducting gap magnitude for the electron-doped band is nearly twice of that of the hole-doped one, which contrasts to our previous understanding of the electron-hole asymmetry in high-T$_c$ superconductors but consistent with recent angle-resolved-photoemission-spectroscopy experiments in four-layered materials Ba$_2$Ca$_3$Cu$_4$O$_8$F$_2$. Our results propose that the pair tunneling effect is important to examine the multi-layered superconducting materials.

description: In this paper a microscopic state-of-the-art approach to calculation of the nuclear matrix element $M^{0ν}$ for neutrinoless double beta decay with an account for nuclear deformation is presented in length and applied for $^{76}$Ge, $^{150}$Nd and $^{160}$Gd. The proton-neutron quasiparticle random phase approximation (QRPA) with a realistic residual interaction [the Brueckner $G$ matrix derived from the charge-depending Bonn (Bonn-CD) nucleon-nucleon potential] is used as the underlying nuclear structure model. The effects of the short range correlations and the quenching of the axial vector coupling constant $g_A$ are analyzed. The results show that neutrinoless double beta decay of $^{150}$Nd, to be measured soon by the SNO+ collaboration, provides one of the best probes of the Majorana neutrino mass. This confirms our preliminary conclusion in Ref. {Fang10}.

Tecnologie dello schermo e abilità visuo-motorie dei bambini

Year: 2014

description: In seguito ad un’analisi di possibili aspetti positivi e negativi dell’utilizzo di tecnologie dello schermo sul bambino, il lavoro si è focalizzato sull’osservazione di un possibile nesso tra uso di tecnologie dello schermo e abilità visuo-motorie in alunni di scuola elementare (SE), più precisamente ragazzi di classe quinta. La presente ricerca è basata su un approccio di tipo descrittivo con dati misti. Dopo aver raccolto, attraverso un questionario, i dati inerenti l’utilizzo delle tecnologie dello schermo da parte dei ragazzi, si è proposto ai soggetti un esercizio di riproduzione di una sequenza visuo-motoria. Nel corso dell’esercizio è stata compilata una tabella d’osservazione, la quale ha permesso di rispondere alle domande di ricerca. Dai dati raccolti sembra emergere che l’utilizzo di tecnologie dello schermo possa sia incrementare che diminuire le abilità visuo-motorie degli alunni. Si è quindi potuto ipotizzare che tali risultati potrebbero dipendere da ciò che il bambino guarda e dal tipo di attività che svolge di fronte agli schermi. Vi è, però, da considerare che altre variabili non testate in questa ricerca potrebbero influire sulle abilità visuo-motorie dei bambini. Pertanto le ore che un alunno trascorre di fronte agli schermi non possono essere considerate come la causa scatenante di eventuali difficoltà visuo-motorie, in quanto esse possono essere legate anche ad altri fattori. Inoltre, dal momento che il campione di alunni preso in considerazione è ristretto non è possibile delinearne una tendenza. Relatore: Luca Botturi.
title: Simple Model for Alkali Leaching from Geopolymers: Effects of Raw Materials and Acetic Acid Concentration on Apparent Diffusion Coefficient
Creators: name: Ukrainczyk, Neven
Publisher: name: MDPI
Year: 2022

description: This paper investigates alkali leaching from geopolymers under various concentrations of acetic acid solutions. The effects of the raw metakaolin purity as well as fly ash-based geopolymer mortars and pastes are considered. A new methodology for (acetic) acid attack is proposed, adapting standard approaches, where the concentration of the leached alkali in the exposure solution is measured over time. The applicability of a simple diffusion-based mathematical model to determine the apparent diffusion coefficient (Dapp) for geopolymer pastes and mortars was validated. At the end of the paste tests, microstructural alterations of the specimens’ cross-sections were analyzed microscopically, revealing occurrence of degradation across the outermost surface parts and, especially under acid attack, the formation of long cracks that connect the surface with the intact inner zone. Drastically different Dapp are discussed in terms of the differences in the mix designs, principally resulting in different alkali-binding capacities of the geopolymers, while the acid promoted dissolution and increased porosity. As a result of this interpretation, it was concluded that Dapp is governed mainly by the chemistry of the alkali release from the gel, as it overruled the effects of porosity and cracks.

description: In the context of the Supersymmetric Standard Model with hierarchical sfermion masses, we re-analyze the QCD corrections to Delta F=2 effective Hamiltonian properly including effects which have been neglected so far. The point is that some Delta F=2 diagrams, involving both the heavy and the light sparticles, exhibit a logarithmic dependence on the ratio between the two masses, signalling a sensitivity to all the momenta between the two scales. In order to properly deal with these terms one has to take into account the mixing between Delta F=1 and Delta F=2 operators. In typical situations this treatment can affect the result at the level of 30% or even more.

description: The theoretical description of the adsorption of proteins at liquid/fluid interfaces suffers from the inapplicability of classical formalisms, which soundly calls for the development of more complicated adsorption models. A Frumkin-type thermodynamic 2-D solution model that accounts for nonidealities of interface enthalpy and entropy was proposed about two decades ago and has been continuously developed in the course of comparisons with experimental data. In a previous paper we investigated the adsorption of the globular protein β-lactoglobulin at the water/air interface and used such a model to analyze the experimental isotherms of the surface pressure, Π(c), and the frequency-, f-, dependent surface dilational viscoelasticity modulus, E(c)f , in a wide range of protein concentrations, c, and at pH 7. However, the best fit between theory and experiment proposed in that paper appeared incompatible with new data on the surface excess, Γ, obtained from direct measurements with neutron reflectometry. Therefore, in this work, the same model is simultaneously applied to a larger set of experimental dependences, e.g., Π(c), Γ(c), E(Π)f , etc., with E-values measured strictly in the linear viscoelasticity regime. Despite this ambitious complication, a best global fit was elaborated using a single set of parameter values, which well describes all experimental dependencies, thus corroborating the validity of the chosen thermodynamic model. Furthermore, we applied the model in the same manner to experimental results obtained at pH 3 and pH 5 in order to explain the well-pronounced effect of pH on the interfacial behavior of β-lactoglobulin. The results revealed that the propensity of β-lactoglobulin globules to unfold upon adsorption and stretch at the interface decreases in the order pH 3 > pH 7 > pH 5, i.e., with decreasing protein net charge. Finally, we discuss advantages and limitations in the current state of the model

description: We propose a new holographic model of Josephson junctions (and networks thereof) based on designer multi-gravity, namely multi-(super)gravity theories on products of distinct asymptotically AdS spacetimes coupled by mixed boundary conditions. We present a simple model of a Josephson junction (JJ) that exhibits the well-known current-phase sine relation of JJs. In one-dimensional chains of holographic superconductors we find that the Cooper-pair condensates are described by a discretized Schrodinger-type equation. Such non-integrable equations, which have been studied extensively in the past in condensed matter and optics applications, are known to exhibit complex behavior that includes periodic and quasiperiodic solutions, chaotic dynamics, soliton and kink solutions. In our setup these solutions translate to holographic configurations of strongly-coupled superconductors in networks with weak site-to-site interactions that exhibit interesting patterns of modulated superconductivity. In a continuum limit our equations reduce to generalizations of the Gross-Pitaevskii equation. We comment on the many possible extensions and applications of this new approach.

Interfacial bond strength of fabric reinforced cementitious matrix : effect of substrate properties and fibre-mortar ratio

description: Fabric Reinforced Cementitious Matrix (FRCM) is a relatively new material used for strengthening applications of reinforced concrete structures. Several studies reported in the literature have indicated that the bond between FRCM layers and the concrete substrate is one of the main factors that affect the performance of the system. Few studies have attempted a combined approach of analyzing the surfaces between the three layers of this composite (fibres-matrix-concrete). An investigation of the bond behavior is studied in this thesis with an emphasis on the fibre-matrix and the concrete-matrix interfaces. The efficacy of surface preparation methods and the existing concrete strength were used to evaluate the bond at the concrete-matrix interface. The fibre-mortar width ratio was used to analyze the bond at the fibre-matrix interface. This experiment was completed in two phases: 72 concrete blocks (150x150x165mm) in double shear testing and 12 small concrete beams (150x150x500mm) in flexural testing. For double shear, the varying parameters included 1) surface preparation (untreated, grinding, sandblasting, shotblasting, and combination), 2) fibre-mortar width ratio (1:1 and 1:2) with fibre widths of 120mm and 60mm, and 3) concrete strength (30MPa and 50MPa). The double shear test results indicated that the bond strength increased with enhanced methods of surface preparation. Surface grooving reduced the debonding response, and combined surface preparation methods were effective at eliminating debonding failures. Also, the fibre-mortar ratio of 1:2 exhibited higher bond strength and reduced bond failure than the 1:1 ratio. The concrete strength had an insignificant effect on the bond strength and failure mode. For flexural specimens, the surface preparation method was examined. The surface preparation had a significant effect on the bond strength, and all failures occurred at the fibre-matrix interface. The bond strength was on average 44.5% higher for the flexural than for the double shear specimens.
