title: Wie viel „falsch“ ist noch „echt“? Überlegungen zum Umgang mit mittelalterlichen Burgruinen anhand von Beispielen in der Schweiz
Creators: name: Schmaedecke, Michael
Publisher: name: University Library Heidelberg
Year: 2013

description: Ausgehend von der Frage „Wie viel ‚falsch’ ist noch ‚echt’?“, bei der es sich um die Grundsatzfrage der Denkmalpflege handelt, wird am Beispiel von Burgruinen der Frage nach dem Umgang mit archäologischen Monumenten nachgegangen. Dabei wird dargelegt, dass einerseits die historische Substanz und damit die Authentizität der Monumente bewahrt werden müssen und andererseits die Monumente für die Öffentlichkeit aufbereitet und ihr als Anschauungsobjekte zum Verständnis ihrer Geschichte zur Verfügung gestellt werden sollen. Während ArchäologInnen und Denkmalpfl egerInnen der Erhaltung der historischen Substanz verpfl ichtet sind, wünscht sich die Öffentlichkeit, für die die Authentizität der Objekte oftmals kaum eine Rolle spielt, einen Gewinn von Erlebniswerten, was sich oftmals nicht miteinander in Deckung bringen lässt.
Anhand von Beispielen w ird dargelegt, dass die Grenze zwischen „echt“ und „falsch“ zerfl ießt und das „Falsche“ vielfach nötig ist, um das historisch „Echte“ darzustellen. Während das „Echte“ eines Objektes unbedingt möglichst lange zu ewahren ist – wobei dessen Zerfall letztendlich nicht aufzuhalten, nur zu verlangsamen ist –, kann „Falsches“ jedoch durchaus sinnvoll sein, um die historische Aussage eines Objektes zu unterstützen.
description: Proceeding from the question „How much ‘wrong’ is still ‘real’?“, which concerns the principle question oft the care of monuments, will be discussed the question about handling with archaeological monuments by the example of castle ruins. It is demonstrated, that on the one hand the historical substance and with it the authenticity of the monuments must be preserved and, on the other hand, the
monuments should be processed for the general public and be made available to her as illustrative objects to the understanding of her history. While archaeologists and conservators of the monuments are obligated to the preservation of the historical substance, the public, for which the authenticity of the objects plays often hardly a role, wishes itself a profi t of experience values, hich often cannot be brought together in cover. On the basis of examples it is demonstrated that the border between „real“ and „false“ dissolves and the „wrong“ often is necessary to show the historical „real“. While the “real” of an monument is to be preserved absolutely as for a long time as possible – whereby its decay is not to stop fi nally, only to be slowed down – the “wrong” however can make sense to support the historical statement of a monument.

description: La transparence de la politique monétaire est un aspect crucial pour toute banque centrale, dans la mesure où elle renforce sa crédibilité, aide à ancrer les anticipations des agents économiques et contribue à la stabilité économique et financière du pays. Les arguments théoriques indiquent que la transparence pourrait accroître la crédibilité d'une politique monétaire à faible inflation, améliorer la performance de la prise de décision et renforcer l'efficacité de la fixation des taux d'intérêt.

Le but de cet article est d’évaluer le développement de la communication et la transparence de la banque centrale marocaine depuis sa création, à travers une lecture dans les avancées réalisées en matière du cadre de conduite de la politique monétaire et les pratiques de communication retenues. L’étude réalisée nous a permis de considérer Bank Almghrib à un stade suffisamment avancé en ce qui concerne la manière dont l’objectif de la politique monétaire est fixé, communiqué et expliqué au public. Ces réalisations permettent de situer le Maroc à un niveau bien développé dans son projet de transition vers la nouvelle politique monétaire de ciblage d’inflation.

description: We establish a local martingale $M$ associate with $f(X,Y)$ under some restrictions on $f$, where $Y$ is a process of bounded variation (on compact intervals) and either $X$ is a jump diffusion (a special case being a Lévy process) or $X$ is some general (cádlág metric space valued) Markov process. In the latter case $f$ is restricted to the form $f(x,y)=\sum_{k=1}^Kξ_k(x)η_k(y)$. This local martingale unifies both Dynkin's formula for Markov processes and the Lebesgue-Stieltjes integration (change of variable) formula for (right continuous) functions of bounded variation. For the jump diffusion case, when further relatively easily verifiable conditions are assumed then this local martingale becomes an $L^2$ martingale. Convergence of the product of this Martingale with some deterministic function (of time) to zero both in $L^2$ and a.s. is also considered and sufficient conditions for functions for which this happens are identified.

description: We experimentally demonstrate that a non-classical state prepared in an atomic memory can be efficiently transferred to a single mode of free-propagating light. By retrieving on demand a single excitation from a cold atomic gas, we realize an efficient source of single photons prepared in a pure, fully controlled quantum state. We characterize this source using two detection methods, one based on photon-counting analysis, and the second using homodyne tomography to reconstruct the density matrix and Wigner function of the state. The latter technique allows us to completely determine the mode of the retrieved photon in its fine phase and amplitude details, and demonstrate its nonclassical field statistics by observing a negative Wigner function. We measure a photon retrieval efficiency up to 82% and an atomic memory coherence time of 900 ns. This setup is very well suited to study interactions between atomic excitations, and to use them in order to create and manipulate more sophisticated quantum states of light with a high degree of experimental control.

Robust quantum data locking from phase modulation

description: Quantum data locking is a unique quantum phenomenon that allows a relatively short key to (un)lock an arbitrarily long message encoded in a quantum state, in such a way that an eavesdropper who measures the state but does not know the key has essentially no information about the encrypted message. The application of quantum data locking in cryptography would allow one to overcome the limitations of the one-time pad encryption, which requires the key to have the same length as the message. However, it is known that the strength of quantum data locking is also its Achilles heel, as the leakage of a few bits of the key or the message may in principle allow the eavesdropper to unlock a disproportionate amount of information. In this paper we show that there exist quantum data locking schemes that can be made robust against information leakage by increasing the length of the shared key by a proportionate amount. This implies that a constant size key can still encrypt an arbitrarily long message as long as a fraction of it remains secret to the eavesdropper. Moreover, we greatly simplify the structure of the protocol by proving that phase modulation suffices to generate strong locking schemes, paving the way to optical experimental realizations. Also, we show that successful data locking protocols can be constructed using random codewords, which very well could be helpful in discovering random codes for data locking over noisy quantum channels.

description: We relate the collective dynamic internal geometric degrees of freedom to the gauge fluctuations in $ν=1/m$(m odd) fractional quantum Hall effects. In this way, in the lowest Landau level, a highly nontrivial quantum geometry in two-dimensional guiding center space emerges from these internal geometric modes. Using the Dirac bracket method, we find that this quantum geometric field theory is a topological non-commutative Chern-Simons theory.Topological indices, such as the guiding center angular momentum (also called the shift) and the guiding center spin, which characterize the fractional quantum Hall (FQH) states besides the filling factor, are naturally defined. A noncommutative K-matrix Chern-Simons theory is proposed as a generalization to a large class of Abelian FQH topological orders.

description: Modular light (ModLight) sources can be integrated into complex systems for microscopy, medical imaging, remote sensing, and so many more. Motivated by the need for affordable and open-access alternatives that are globally relevant, we have designed and shared light devices that use simple, off-the-shelf components. Red, green, blue, white and near-infrared LEDs are combined using mirrors and X-Cube prisms in novel devices. This modular nature allows portability and mounting flexibility. The ModLight suite can be used with any optical system that requires single- or multi-wavelength illumination such as bright-field and epifluorescence
 microscopes.

Sudden Decoherence Transitions for Quantum Discord

Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We investigate the disappearance of discord in 2- and multi-qubit systems subject to decohering influences. We formulate the computation of quantum discord in terms of the generalized Bloch vector, which gives useful insights on the time evolution of quantum coherence for the open system, particularly the comparison of entanglement and discord. And we show that the analytical calculation of the global geometric discord is NP-hard in the number of qubits. We present an efficient numerical method to calculating the quantum discord for a certain important class of multipartite states. In agreement with previous work for 2-qubit cases, (Mazzola et al., Phys. Rev. Lett. 104, 200401 (2010)), we find situations in which there is a sudden transition from classical to quantum decoherence characterized by the discord remaining relatively robust (classical decoherence) until a certain point from where it begins to decay quickly whereas the classical correlation decays more slowly (quantum decoherence). However, we find that as the number of qubits increases, the chance of this kind of transition occurring becomes small.

description: We parametrize a large class of corrections to general relativity which include a long-ranged gravitational scalar field as a dynamical degree of freedom in two ways: parametrizing the structure of the correction to the action, and parametrizing the scalar hair (multipole structure) that compact objects and black holes attain. The presence of this scalar hair violates the no-hair theorems present in general relativity, which leads to several important effects. The effects we consider are (i) the interaction between an isolated body and an external scalar field, (ii) the scalar multipole-multipole interaction between two bodies in a compact binary, (iii) the additional pericenter precession of a binary, (iv) the scalar radiation from a binary, and (v) the modification to the gravitational wave phase from a binary. We apply this framework to example theories including Einstein-dilaton-Gauss-Bonnet gravity and dynamical Chern-Simons gravity, and estimate the size of the effects. Finally, we estimate the bounds that can be placed on parameters of the theories from the precession of pulsar binaries and from gravitational waves.

The two texture/cofactor zero conditions give four constraints, which in conjunction with the five measured oscillation parameters completely determine the nine independent real parameters of the neutrino mass matrix. We also study the implications that future measurements of neutrinoless double beta decay and the Dirac CP phase will have on these cases.

title: Professorinnen in der Ur- und Frühgeschichte. Gender und Archäologie
Creators: name: Bräuning, Andrea
Publisher: name: University Library Heidelberg
Year: 2013

description: In meinem Beitrag werde die Karriereverläufe der ersten vier habilitierten Frauen im Fach Ur- und Frühgeschichte an deutschen Universitäten beleuchtet und mit den Karrieren der zweiten und dritten Generation verglichen. Dabei zeigt es sich zum einen, dass selbst bedeutende Archäologinnen nicht nur durch ihr Werk reüssieren, sondern die Erinnerung an sie auch „gemacht“ wird. Zum anderen stellen wir fest, dass der Anteil der Professorinnen in Deutschland nach wie vor nur minimal steigt, die Zahl der habilitierten Frauen hingegen wesentlich höher ist. Es wird deshalb der Frage nachgegangen, ob es typisch weibliche Karriereverläufe gibt und zu welchem Zeitpunkt der Karriereknick einsetzt. Eine Änderung dieser Situation ist ohne eine gezielte Steuerung nicht in Sicht. Neben den bestehenden Frauenförderprogrammen und Netzwerken sowie der Aktivität der Frauenbeauftragten, sind sicher auch finanzielle Anreize für die Fakultäten, Frauen zu berufen, probate Mittel, um den Frauenanteil zu steigern.
description: My treatise explores the career paths of the first four habilitated women in Prehistory and Early History at German universities in comparison with the career paths of the second and third generation. On the one hand, it shows that even leading female archaeologists do not only succeed through their work; it is also the memorial that is erected in their honour. On the other hand, we note that the proportion of women professors is still increasing; the number of habilitated women, however, is considerably higher. For this reason, the treatise explores the question of whether there are typical female career paths and when a career setback happens. The situation is not likely to change without a target-oriented control. Apart from the existing support programmes and networks for women as well as the activities of a women’s representative, financial incentives for faculties appointing more women are certainly an effective means to increase the proportion of women.
Ferromagnetic cluster-glass state in itinerant electron system Sr1-xLaxRuO3

description: The magnetic and electronic properties of Sr1-xLaxRuO3 were studied by means of dc-magnetization, ac-susceptibility, specific heat, and electrical resistivity measurements. The dc-magnetization and ac-susceptibility measurements have revealed that the transition temperature and the ordered moment of the ferromagnetic order are strongly suppressed as La is substituted for Sr. The ac-susceptibility exhibits a peak at T* due to the occurrence of spontaneous spin polarization. Furthermore, we observed that T* shows clear frequency variations for x>= 0.3. The magnitude of the frequency shifts of T* is comparable to that of cluster-glass systems, and the frequency dependence is well described in terms of the Vogel-Fulcher law. On the other hand, it is found that the linear specific heat coefficient gamma enhances with the suppression of the ferromagnetic order. The relatively large gamma values reflect the presence of the Ru 4d state at Fermi level, and hence, the magnetism of this system is considered to be tightly coupled with the itinerant characteristics of the Ru 4d electrons. The present experimental results and analyses suggest that the intrinsic coexistence of the spatially inhomogeneous magnetic state and the itinerant nature of the Ru 4d electrons is realized in this system, and such a feature may be commonly involved in La- and Ca-doped SrRuO3.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The MT2 or "s-transverse mass" statistic was developed to associate a parent mass scale to a missing transverse energy signature, given that escaping particles are generally expected in pairs, while collider experiments are sensitive to just a single transverse momentum vector sum. This document focuses on the generalized extension of that statistic to asymmetric one- and two-step decay chains, with arbitrary child particle masses and upstream missing transverse momentum. It provides a unified theoretical formulation, complete solution classification, taxonomy of critical points, and technical algorithmic prescription for treatment of the MT2 event scale. An implementation of the described algorithm is available for download, and is also a deployable component of the author's selection cut software package AEACuS (Algorithmic Event Arbiter and Cut Selector). Appendices address combinatoric event assembly, algorithm validation, and a complete pseudocode.

description: We investigate background metrics for 2+1-dimensional holographic theories where the equilibrium solution behaves as a perfect fluid, and admits thus a thermodynamic description. We introduce stationary perfect-Cotton geometries, where the Cotton--York tensor takes the form of the energy--momentum tensor of a perfect fluid, i.e. they are of Petrov type D_t. Fluids in equilibrium in such boundary geometries have non-trivial vorticity. The corresponding bulk can be exactly reconstructed to obtain 3+1-dimensional stationary black-hole solutions with no naked singularities for appropriate values of the black-hole mass. It follows that an infinite number of transport coefficients vanish for holographic fluids. Our results imply an intimate relationship between black-hole uniqueness and holographic perfect equilibrium. They also point towards a Cotton/energy--momentum tensor duality constraining the fluid vorticity, as an intriguing boundary manifestation of the bulk mass/nut duality.

description: Population III stars are believed to have been more massive than typical stars today and to have formed in relative isolation. The thermodynamic impact of metals is expected to induce a transition leading to clustered, low-mass Population II star formation. In this work, we present results from three cosmological simulations, only differing in gas metallicity, that focus on the impact of metal fine-structure line cooling on the formation of stellar clusters in a high-redshift atomic cooling halo. Introduction of sink particles allows us to follow the process of gas hydrodynamics and accretion onto cluster stars for 4 Myr corresponding to multiple local free-fall times. At metallicities at least $10^{-3}\, Z_{\odot}$, gas is able to reach the CMB temperature floor and fragment pervasively resulting in a stellar cluster of size $\sim1$ pc and total mass $\sim1000\, M_{\odot}$. The masses of individual sink particles vary, but are typically $\sim100\, M_{\odot}$, consistent with the Jeans mass when gas cools to the CMB temperature, though some solar mass fragments are also produced. At the low metallicity of $10^{-4}\, Z_{\odot}$, fragmentation is completely suppressed on scales greater than 0.01 pc and total stellar mass is lower by a factor of 3 than in the higher metallicity simulations. The sink particle accretion rates, and thus their masses, are determined by the mass of the gravitationally unstable gas cloud and the prolonged gas accretion over many Myr. The simulations thus exhibit features of both monolithic collapse and competitive accretion. Even considering possible dust induced fragmentation that would occur at higher densities, the formation of a bona fide stellar cluster seems to require metal line cooling and metallicities of at least $10^{-3}\, Z_{\odot}$.

description: Motivated by recent developments on calculus in metric measure spaces $(X,\mathsf d,\mathfrak m)$, we prove a general duality principle between Fuglede's notion of $p$-modulus for families of finite Borel measures in $(X,\mathsf d)$ and probability measures with barycenter in $L^q(X,\mathfrak m)$, with $q$ dual exponent of $p\in (1,\infty)$. We apply this general duality principle to study null sets for families of parametric and non-parametric curves in $X$. In the final part of the paper we provide a new proof, independent of optimal transportation, of the equivalence of notions of weak upper gradient based on $p$-Modulus (Koskela-MacManus '98, Shanmugalingam '00) and suitable probability measures in the space of curves (Ambrosio-Gigli-Savare '11)

description: Diese Arbeit hinterfragt die in der Literatur mehrmals auftauchende Aussage, dass Waldpilze in der Schweiz nördlich der Alpen bereits vor dem 19. Jahrhundert eine weitverbreitete Nahrung waren.
Dafür wird auf eine Vielzahl von Originalquellen zurückgegriffen, welche durch einige Werke von Historikern ergänzt werden. In einem ersten Teil wird die Geschichte des Pilzkonsums in den Nachbarländern der Schweiz betrachtet. Gesellschaftliche Akzeptanz, Handel und Konsum werden beleuchtet. Es wird aufgezeigt, in welchem Ausmass Pilze in diesen Ländern seit über drei Jahrhunderten genutzt werden.
Für die Schweiz ergibt sich ein anderes Bild. Bis Ende des 18. Jahrhunderts werden Pilze hier äusserst selten gegessen. Die Bemühungen der öffentlichen Hand, Pilze in der Bevölkerung bekannt zu machen, setzen zu dieser Zeit ein und dauern bis Anfang 20. Jahrhundert an. Diese Zeitspanne wird besonders ausführlich betrachtet, wobei vorwiegend Quellen aus den Bereichen Medizin, Ernährung, Botanik und Wortkunde Erwähnung finden.
Es zeigt sich, dass Kultur und Tradition vorwiegend bestimmen, ob von einer Gesellschaft Pilze gegessen werden und der Konsum unabhängig vom Angebot an Wildpilzen ist.

description: Universal spacetimes are spacetimes for which all conserved symmetric rank-2 tensors, constructed as contractions of polynomials from the metric, the Riemann tensor and its covariant derivatives of arbitrary order, are multiples of the metric. Consequently, metrics of universal spacetimes solve vacuum equations of all gravitational theories with Lagrangian being a polynomial curvature invariant constructed from the metric, the Riemann tensor and its derivatives of arbitrary order. In the literature, universal metrics are also discussed as metrics with vanishing quantum corrections and as classical solutions to string theory. Widely known examples of universal metrics are certain Ricci-flat pp waves. In this paper, we start a general study of geometric properties of universal metrics in arbitrary dimension and we arrive at a broader class of such metrics. In contrast with pp waves, these universal metrics also admit non-vanishing cosmological constant and in general do not have to possess a covariantly constant or recurrent null vector field. First, we show that a universal spacetime is necessarily a CSI spacetime, i.e. all curvature invariants constructed from the Riemann tensor and its derivatives are constant. Then we focus on type N spacetimes, where we arrive at a simple necessary and sufficient condition: a type N spacetime is universal if and only if it is an Einstein Kundt spacetime. A class of type III Kundt universal metrics is also found. Several explicit examples of universal metrics are presented.

description: Adult molluscs produce shells with diverse morphologies and ornamentations, different colour patterns and microstructures. The larval shell however, is a phenotypically more conserved structure. How do developmental and evolutionary processes generate varying diversity at different life-history stages? Using live-imaging, histology, scanning electron microscopy and transcriptomic profiling, we have described shell development in a heteroconchian bivalve the Antarctic clam, Laternula elliptica and compared it to adult shell secretion processes in the same species. Adult downstream shell genes, such as those encoding extracellular matrix proteins and biomineralization enzymes, were largely not expressed during shell development, and instead, a development-specific downstream gene repertoire was expressed. Upstream regulatory genes such as transcription factors and signalling molecules were conserved between developmental and adult shell secretion. Comparing heteroconchian data with recently reported pteriomorphian larval shell development data suggest that, despite being phenotypically more conserved, the downstream effectors constituting the larval shell ‘tool-kit’ may be as diverse as that of adults. Overall, our new data suggest that a larval shell formed using development-specific downstream effector genes is a conserved and ancestral feature of the bivalve lineage, and possibly more broadly across the molluscs.

description: Hybrid zones are dynamic areas where populations of two or more interbreeding species may change through an influx of novel genetic material resulting from hybridization or selection on standing genetic variation. Documenting changes in populations through time, however, is challenging because repeated samples are often missing or because long-term storage can affect trait morphologies, especially colour traits that may fade through time. We document a change in carotenoid-based orange breast feathers of Bullock's Orioles (Icterus bullockii) from the Great Plains hybrid zone, USA. Contemporary Bullock's Orioles are more orange than historic individuals from the same location sampled approximately 60 years ago. Spectrophotometry revealed that contemporary Bullock's resemble orange colour profiles of Baltimore Orioles (I. galbula), the species with which they hybridize. Fading or changes in diet hypotheses do not appear to explain the shift in colour we report for Bullock's Orioles. We propose that these changes in colour are facilitated through introgression with Baltimore Orioles, and favoured by females that choose brighter, more orange males. Our study highlights the long memory of natural history collections and how they offer new insights to the dynamic roll of hybrid zones in trait evolution between interacting species.

description: The need of fast distributed solvers for optimization problems in networked systems has motivated the recent development of the Fast-Lipschitz optimization framework. In such an optimization, problems satisfying certain qualifying conditions, such as monotonicity of the objective function and contractivity of the constraints, have a unique optimal solution obtained via fast distributed algorithms that compute the fixed point of the constraints. This paper extends the set of problems for which the Fast-Lipschitz framework applies. Existing assumptions on the problem form are relaxed and new and generalized qualifying conditions are established by novel results based on Lagrangian duality. It is shown for which cases of more constraints than decision variables, and less constraints than decision variables Fast-Lipschitz optimization applies. New results are obtained by imposing non strict monotonicity of the objective functions. The extended Fast-Lipschitz framework is illustrated by a number of examples, including a non-linear optimal control problem.

Semi-Analytic Stochastic Linearization for Range-Based Pose Tracking

description: In range-based pose tracking, the translation and rotation of an object with respect to a global coordinate system has to be estimated. The ranges are measured between the target and the global frame. In this paper, an intelligent decomposition is introduced in order to reduce the computational effort for pose tracking. Usually, decomposition procedures only exploit conditionally linear models. In this paper, this principle is generalized to conditionally integrable substructures and applied to pose tracking. Due to a modified measurement equation, parts of the problem can even be solved analytically.

description: The aim of the project was to support practitioners in Wales to develop a clearer concept3ual and operational understanding of how existing statutory frameworks and concepts like the Well-being of Future Generations (Wales) Act (2015) (WFGA), Foundational Economy (FE)/Community Wealth Building (CWB), Circular Economy (CE) and Social Value can be incorporated within their processes, and practices. The project designed a workshop, informed by social learning theory, to achieve this aim. The workshops were designed to enable practitioners to engage with the terms and reflect on examples of implementation of the concepts with peers to ‘sensemake’ through a shared narrative process. The participants were supported to discuss the terms and start to develop plans on how to implement the principles of each concept within their workplaces.We delivered the facilitated workshop, seven times across Wales, to provide practitioners with an opportunity to reflect, discuss and begin to develop plans that mitigate the ambiguity and conceptual confusion that exists within Public Sector Organisations (PSOs) around the above concepts.The programme was split into three phases:1. Engagement and coproduction2. Workshop delivery3. Project Impact capture and disseminationThe programme ran from 1 March 2023 to 30 November 2023.
