description: Interdependencies between experimental spectra, representing line or plane projections of electronic densities, are derived from their consistency and symmetry conditions. Some additional relations for plane projections are obtained by treating them as line projections of line projections. The knowledge of these dependencies can be utilised both for an improvement of experimental data and for a verification of various techniques used for correcting e.g. two-dimensional (or one-dimensional) angular correlation of annihilation radiation spectra and Compton scattering profiles.

title: Undoing Big Daddy Art: Subverting the Fathers of Western Art Through a Metaphorical and Mythological Father/Daughter Relationship

description: The canon of Western art history provides a selection of artists that have supposedly made an 'original' contribution to stylistic innovation within the visual arts. Although a process of selection cannot be avoided, this procedure has resulted in a Eurocentric and patriarchal art canon. For example, the Western art canon consists of certain white male artists who are given exclusive authority and are often referred to as the 'fathers of art'. As the status of a 'father of art' pertains to the highest level of achievement within artistic creativity, I argue that this excellence in creativity is based on a gender specific criteria. This issue refers to the patrilineage within Western art history and how this father-son model, in a general sense, excludes women artists from the canon. Further, the very few women included in the art canon are not given the equivalent status as a 'father of art'. I address this patriarchal bias through focussing on the father/daughter relationship as a way of challenging the patrilineage within Western art history's patrilineage. Through this process of intervention, I position the daughter an assertive figure who directly confronts the fathers of Western art. Within this confrontation, I emphasise that the daughter has an assertive identity that is also beyond the father. On this premise my paper is based on the argument that the application of a father/daughter model, within a metaphorical and mythological sense, is useful in subverting the father figures within Western art history. That is, I construct myself as the metaphorical and mythological daughter of the Dada artist, Marcel Duchamp and the Fluxus artist, Joseph Beuys. As an assertive daughter, I insert myself into the patriarchal framework surrounding these two canonical figures in order to decentre and subvert their authority and phallocentric art practice. It is important to note that both Duchamp and Beuys are addressed as case studies (not as individual arguments) that illustrate the patriarchal constructs of the art canon. Within this premise, I draw upon the female artists Sherrie Levine and Jana Sterbak who directly subvert Western father figures as examples of assertive daughter identities. Within this exploration of the assertive daughter identity, I discuss feminist psychoanalysis (particularly the 'object relations' theorist Nancy Chodorow and the French feminist, Luce Irigaray) in order to offer metaphorical representations of the assertive daughter. These metaphors also assist in subverting the gender (male) specific criteria for creativity under the 'law of the father'.

description: The hybridization of $σ$ and $π$ orbitals of carbon atoms in graphene depends on the surface curvature. Considering a single junction between flat and rippled graphene subsystems, it is found an accumulation of charge in the rippled subsystem due to Klein penetration phenomenon that gives rise to n-p junction. Using this fact, we show that the momentum distribution of electrons in ballisitically propagating beam can be selective without a waveguide, or external electric, and/or magnetic fields in graphene strip under experimentally feasible one-dimensional periodic potential. Such a potential is created with the aid of superlattice that consists of periodically repeated graphene pieces withdifferent hybridizations of carbon orbits, produced by variation of the graphene surface curvature. The charge redistribution and selected transmission of electrons, caused by the superlattice, allows to control the electron focusing in the considered system by simply changing the element properties in the superlattice

description: Objectives: Neck circumference (NC) has been associated with cardiovascular disease and metabolic syndrome. However, the association between NC and frailty remains unknown. We aimed to determine the relationship between frailty and NC in middle-aged and elderly women. Methods: Frailty was diagnosed based on the Japanese version of the Cardiovascular Health Study criteria. Of women who underwent health checkup, 295 women with the following measurements were targeted: four trunk circumferences and appendicular skeletal muscle index (aSMI) measured using bioelectrical impedance analysis; albumin, total cholesterol, triglycerides, and C-reactive protein levels measured using a blood test; and physical function measured using back muscle strength and timed up-and-go test (TUG). Normal and frailty group comparisons were conducted using a statistical method. Results: Significant differences were observed between the two groups in terms of age, body mass index, all trunk circumferences, aSMI, back muscle strength, and TUG. Logistic regression analysis showed that NC was more related with frailty among the four trunk circumferences. In multiple regression analysis, declining NC was significantly associated with frailty. Conclusion: In middle-aged and elderly women, NC has a significant association with frailty. Declining NC was shown to be an anthropometric marker of frailty, and may be a frailty risk factor.

description: Set-based reasoning and conditional language are two critical components of deductive argumentation and facility with proof. The purpose of this qualitative study was to describe the role of truth value and the solution set in supporting the development of the ability to reason about classes of objects and use conditional language. This study first examined proof schemes – how students convince themselves and persuade others – of Algebra I students when justifying solutions to routine and non-routine equations. After identifying how participants learned to use set-based reasoning and conditional language in the context of solving equations, the study then determined if participants would employ similar reasoning in a geometrical context. As a whole, the study endeavored to describe a possible trajectory for students to transition from non-deductive justifications in an algebraic context to argumentation that supports proof writing. First, task-based interviews elicited how participants became absolutely certain about solutions to equations. Next, a teaching experiment was completed to identify how participants who previously accepted empirical arguments as proof shifted to making deductive arguments. Last, additional task-based interviews in which participants reasoned about the relationship between Varignon Parallelograms and Varignon Rectangles were conducted. The first set of task-based interviews found that a majority of participants displayed ritualistic proof schemes – they viewed equations as prompts to execute processes and solutions as results, or “answers.” Approximately half of participants employed empirical proof schemes; they described convincing themselves or others using a range of arguments that do not constitute valid proof. One particularly noteworthy finding was that no participants initially used deductive justifications to reach absolute certainty. Participants successfully adopted set-based reasoning and learned to use conditional language by progressively accommodating a series of understandings. They later utilized their new ways of reasoning in the geometrical context. Participants employed the implication structure, discriminated between necessary and sufficient conditions, and maintained a disposition of doubt toward empirical evidence. Finally, implications of these findings for pedagogues and researchers, as well as future directions for research, are discussed.

description: We review recent results on the appearance of long-term persistence in climatic records and their relevance for the evaluation of global climate models and rare events.The persistence can be characterized, for example, by the correlation C(s) of temperature variations separated by s days.We show that, contrary to previous expectations, C(s) decays for large s as a power law, C(s) ~ s^(-gamma). For continental stations, the exponent gamma is always close to 0.7, while for stations on islands gamma is around 0.4. In contrast to the temperature fluctuations, the fluctuations of the rainfall usually cannot be characterized by long-term power-law correlations but rather by pronounced short-term correlations. The universal persistence law for the temperature fluctuations on continental stations represents an ideal (and uncomfortable) test-bed for the state of-the-art global climate models and allows us to evaluate their performance. In addition, the presence of long-term correlations leads to a novel approach for evaluating the statistics of rare events.

Historic buildings--Conservation and restoration

description: This thesis is a study of the Chinese academies as they currently exist and the protections they have as historic structures and places. Given the large number of academies and their widely distributed locations, Hunan academies are selected for case studies, seeking commonalities with respect to the types of buildings, their locations, their current uses, the state of their conservation and their success as historic sites well recognized by the local and national community. The governance framework of heritage conservation in China follows a top down policy-making structure. Although current legislation has secured basic legal protections on cultural heritage sites, the lack of precise interpretation of the law has consequently vested great autonomy during the implementation process and thus resulted in situations where overlooked academies are subject to material loses and shallow interpretations. To the case studies individually and as a group reveal the various forces and conditions impacting and controlling the current preservation strategies for these designated heritage sites. They also permit consideration of the opportunities and threats which arise in a variety of situations, emphasizing the overarching ideas of preserving the architectural integrity with respect to academies’ educational nature and cultural influence as well as the thorough presentation of the broad spectrum of academy history. Although it is inevitable that many of the academies have to adjust their functions and building layout to accommodate the requirements of current conservation planning, it is an assumption underlying these analyses that, first and foremost, the cultural and historical significance of Hunan academies should not be compromised.

Subjects: subject: Mathematics

description: In this thesis we present an adaptation of the Hardy-Littlewood Circle Method to give estimates for the number of curves in a variety over a finite field. The key step in the classical Circle Method is to prove that some cancellation occurs in some exponential sums. Using a theorem of Katz, we reduce this to bounding the dimension of some singular loci. The method is fully carried out to estimate the number of rational curves in a Fermat hypersurface of low degree and some suggestions are given as to how to handle other cases. We draw geometrical consequences from the main estimates, for instance the irreducibility of the space of rational curves on a Fermat hypersurface in a given degree range, and a bound on the dimension of the singular locus of the moduli space.

description: We describe resistive states of the system combining two types of orderings - superconducting and ferromagnetic one. It is shown that in the presence of magnetization dynamics such systems become inherently dissipative and in principle cannot sustain any amount of the superconducting current because of the voltage generated by the magnetization dynamics. We calculate generic current-voltage characteristics of a superconductor/ferromagnet/superconductor Josephson junction with an unpinned domain wall and find the low-current resistance associated with the domain wall motion. We suggest the finite slope of Shapiro steps as the characteristic feature of the regime with domain wall oscillations driven by the ac external current flowing through the junction.

description: We present fully quantum-mechanical magnetotransport calculations for short-period lateral superlattices with one-dimensional electrostatic modulation. A non-perturbative treatment of both magnetic field and modulation potential proves to be necessary to reproduce novel quantum oscillations in the magnetoresistance found in recent experiments in the resistance component parallel to the modulation potential. In addition, we predict oscillations of opposite phase in the component perpendicular to the modulation not yet observed experimentally. We show that the new oscillations originate from the magnetic miniband structure in the regime of overlapping minibands.

description: The Jiangmen Underground Neutrino Observatory is proposed to determine neutrino mass hierarchy using a 20~ktonne liquid scintillator detector. Strict radio-purity requirements have been put forward for all the components of the detector. According to the MC simulation results, the radon dissolved in the water Cherenkov detector should be below 200~mBq/m$^3$. Radium, the progenitor of radon, should also be taken seriously into account. In order to measure the radium concentration in water, a radium measurement system, which consists of a radium extraction system, a radon emanation chamber and a radon concentration measurement system, has been developed. In this paper, the updated radon concentration in gas measurement system with a one-day-measurement sensitivity of $\sim$5~mBq/m$^3$, the detail of the development of the radium concentration in water measurement system with a sensitivity of $\sim$23~mBq/m$^3$ as well as the measurement results of Daya Bay water samples will be presented.

description: We consider the survival probability of a particle in the presence of a finite number of diffusing traps in one dimension. Since the general solution for this quantity is not known when the number of traps is greater than two, we devise a perturbation series expansion in the diffusion constant of the particle. We calculate the persistence exponent associated with the particle's survival probability to second order and find that it is characterised by the asymmetry in the number of traps initially positioned on each side of the particle.

description: Starting from deformation quantization (star-products), the quantization problem of Nambu Mechanics is investigated. After considering some impossibilities and pushing some analogies with field quantization, a solution to the quantization problem is presented in the novel approach of Zariski quantization of fields (observables, functions, in this case polynomials). This quantization is based on the factorization over ${\Bbb R}$ of polynomials in several real variables. We quantize the infinite-dimensional algebra of fields generated by the polynomials by defining a deformation of this algebra which is Abelian, associative and distributive. This procedure is then adapted to derivatives (needed for the Nambu brackets), which ensures the validity of the Fundamental Identity of Nambu Mechanics also at the quantum level. Our construction is in fact more general than the particular case considered here: it can be utilized for quite general defining identities and for much more general star-products.

description: This work studies the denoising of piecewise smooth graph signals that exhibit inhomogeneous levels of smoothness over a graph, where the value at each node can be vector-valued. We extend the graph trend filtering framework to denoising vector-valued graph signals with a family of non-convex regularizers, which exhibit superior recovery performance over existing convex regularizers. Using an oracle inequality, we establish the statistical error rates of first-order stationary points of the proposed non-convex method for generic graphs. Furthermore, we present an ADMM-based algorithm to solve the proposed method and establish its convergence. Numerical experiments are conducted on both synthetic and real-world data for denoising, support recovery, event detection, and semi-supervised classification.

description: The communicative function of primates' self-directed behaviours like scratching has gained increasing attention in recent years, but their intentional use is still debated. Here, we addressed this issue by exploring the communicative function of ‘loud scratches’ in wild Sumatran orangutans. Building on previous studies in chimpanzees, we examined the prediction that audio-visual loud scratches are used communicatively in mother–infant travel coordination. Specifically, we examined whether individual, social and scratch features affected the use of pre-move scratches, markers of intentional signal use and approach responses. We analysed a total of 1457 scratching bouts, produced by 17 individuals (including four mothers and their dependent offspring) observed during 305 h of focal follows. Overall, we found that scratching bouts preceded departure mainly when these were produced by mothers and showed features of exaggeration. If the scratching individual was a mother, associates were more likely to be visually attentive during pre-move scratches than in other contexts. Approach or follow responses to scratches by individuals in association were predicted by context, the relationship with the scratcher (i.e. offspring) and the associate's attentional state. We conclude that orangutan mothers use loud scratches as communicative strategies to coordinate joint travel with their infants.

description: Protected area managers often face the challenge of conserving biodiversity while at the same time providing tourism and recreational opportunities for visitors. Popular nature based activities in more remote mountain protected areas include sightseeing, hiking and mountaineering. There are often commercial services provided to support these activities including pack animals for transport and campsite services. These, along with general visitor use, can result in a range of ecological impacts on soils, vegetation, wildlife and aquatic systems. In mountain ecosystems, impacts on vegetation are particularly important as alpine plants often have limited capacity to recover from damage due to the short growing season and poor soils. While a range of impacts from visitor use have been documented in alpine ecosystems in the Northern Hemisphere, there is limited research in the Southern Hemisphere. This is particularly true for the Andes, even though they account for 13% of the world’s mountains and are increasingly popular destinations for hiking and mountaineering. Prior to this thesis, for example, there was only one Masters thesis that assessed visitor impacts in the highest protected area in the Southern Hemisphere, Aconcagua Provincial Park in the dry Andes of Argentina, despite the Park receiving over 33,000 visitors per year. Impacts of visitor use on vegetation in this Park and other protected areas in the dry Andes is of particular concern as visitor use tends to be concentrated in the few areas where vegetation is found. This includes concentrated visitor use of alpine steppe vegetation (29.5% of the Park) and alpine meadows (0.4%) in Aconcagua Park. This thesis assesses the ecological impacts of increasing visitor use of Aconcagua Provincial Park, including impacts on vegetation.

description: Birational Calabi-Yau threefolds in the same deformation family provide a `weak' counterexample to the global Torelli problem, as long as they are not isomorphic. In this paper, it is shown that deformations of certain desingularized weighted complete intersections provide examples of families containing birational varieties. The constructed examples are shown to be non-isomorphic using a specialization argument.

description: The improvement in resolution of climate models has always been mentioned as one of the most important factors when investigating past climatic conditions, especially in order to evaluate and compare the results against proxy data. Despite this, only a few studies have tried to directly estimate the possible advantages of highly resolved simulations for the study of past climate change. Motivated by such considerations, in this paper we present a set of high-resolution simulations for different time slices of the mid-to-late Holocene performed over Europe using the state-of-the-art regional climate model COSMO-CLM. After proposing and testing a model configuration suitable for paleoclimate applications, the aforementioned mid-to-late Holocene simulations are compared against a new pollen-based climate reconstruction data set, covering almost all of Europe, with two main objectives: testing the advantages of high-resolution simulations for paleoclimatic applications, and investigating the response of temperature to variations in the seasonal cycle of insolation during the mid-to-late Holocene. With the aim of giving physically plausible interpretations of the mismatches between model and reconstructions, possible uncertainties of the pollen-based reconstructions are taken into consideration. Focusing our analysis on near-surface temperature, we can demonstrate that concrete advantages arise in the use of highly resolved data for the comparison against proxy-reconstructions and the investigation of past climate change. Additionally, our results reinforce previous findings showing that summertime temperatures during the mid-to-late Holocene were driven mainly by changes in insolation and that the model is too sensitive to such changes over Southern Europe, resulting in drier and warmer conditions. However, in winter, the model does not correctly reproduce the same amplitude of changes evident in the reconstructions, even if it captures the main pattern of the pollen data set over most of the domain for the time periods under investigation. Through the analysis of variations in atmospheric circulation we suggest that, even though the wintertime discrepancies between the two data sets in some areas are most likely due to high pollen uncertainties, in general the model seems to underestimate the changes in the amplitude of the North Atlantic Oscillation, overestimating the contribution of secondary modes of variability.

description: JPEG is the most popular image format, which is widely used in our daily life. Therefore, reversible data hiding (RDH) for JPEG images is important. Most of the RDH schemes for JPEG images will cause significant distortions and large file size increments in the marked JPEG image. As a special case of RDH, the lossless data hiding (LDH) technique can keep the visual quality of the marked images no degradation. In this paper, a novel high capacity LDH scheme is proposed. In the JPEG bitstream, not all the variable length codes (VLC) are used to encode image data. By constructing the mapping between the used and unused VLCs, the secret data can be embedded by replacing the used VLC with the unused VLC. Different from the previous schemes, our mapping strategy allows the lengths of unused and used VLCs in a mapping set to be unequal. We present some basic insights into the construction of the mapping relationship. Experimental results show that most of the JPEG images using the proposed scheme obtain smaller file size increments than previous RDH schemes. Furthermore, the proposed scheme can obtain high embedding capacity while keeping the marked JPEG image with no distortion.

description: Working in the Palatini formalism, we describe a procedure for constructing degenerate solutions of general relativity on 4-manifold M from certain solutions of 2-dimensional BF theory on any framed surface Sigma embedded in M. In these solutions the cotetrad field e (and thus the metric) vanishes outside a neighborhood of Sigma, while inside this neighborhood the connection A and the field E = e ^ e satisfy the equations of 4-dimensional BF theory. Moreover, there is a correspondence between these solutions and certain solutions of 2-dimensional BF theory on Sigma. Our construction works in any signature and with any value of the cosmological constant. If M = R x S for some 3-manifold S, at fixed time our solutions typically describe `flux tubes of area': the 3-metric vanishes outside a collection of thickened links embedded in S, while inside these thickened links it is nondegenerate only in the two transverse directions. We comment on the quantization of the theory of solutions of this form and its relation to the loop representation of quantum gravity.

description: The sharp constants in a family of exponential Sobolev type inequalities in Gauss space are exhibited. They constitute the Gaussian analogues of the Moser inequality in the borderline case of the Sobolev embedding in the Euclidean space. Interestingly, the Gaussian results have features in common with the Euclidean ones, but also reveal marked diversities.

description: Afghan Higher Education has become the most sensitive field of reforms on all levels of governance: rule of law, welfare and security. Compared to primary and secondary education, access to the universities is still a neuralgic point for status distribution and the stabilization of the entire system of education. Admission policies and traditional forms of reproduc- ing disciplinary elites endanger a differentiated development of qualifications and diversified status. The Afghan system will need its own research in Higher Education, and then must develop a minimal base for disciplinary research. It is likely that Higher Education will play an important role during the transformation period 2014-2024 in fields like urbanization, emerg- ing middle class elite, and serving schools by improved teacher training. It will be central to peace-building processes by comprehensive reforms in its governance structure. How much state will be needed in order to provide fair and equal access to the common good of Higher Education, and how much private and individual initiative must emerge in order to create quality and stability of the system? – These are central questions of this working paper.
description: Das afghanische Hochschulsystem hat unter den Gewalteinwirkungen eines dreißigjährigen Krieges stark gelitten und kann die Erfordernisse eines modernen tertiären Sektors nicht erfüllen. Diese sind ihm durch die Intervention ab 2001 und die Aussicht auf eine Transfor- mationsperiode 2014-2024 aber auferlegt. Die Governance von Hochschulsystemen greift tief in das Rechtssystem, in die Wohlfahrtspolitik und in die Gewährleistung von Sicherheit ein. Nicht nur Legitimation durch Statuszuweisung und Effektivität durch Allokation von Quali- fikationen auf dem Arbeitsmarkt sind gefragt. Die Zulassungspolitik zur Universität kann schon vor der Politisierung durch die Hochschule zu gewaltsamer Destabilisierung führen. Die Einbettung der afghanischen Hochschulen in das globale System der akademischen Re- geln wird ebenso erörtert wie Beispiele für Fehlentwicklungen und mögliche Reformen. Für weiteren friedlichen Aufbau sind bestimmte Voraussetzungen im Hochschulbereich auch de- shalb zwingend, weil sie Entscheidungen über den Grad an Staatlichkeit und nichtstaatlicher Initiative festlegen sollten.
