description: With their excellent photometric precision and dramatic increase in monitoring frequency, future microlensing survey experiments are expected to be sensitive to very short time-scale, isolated events caused by free-floating and wide-separation planets with mass as low as a few lunar masses. We estimate the probability of measuring the Einstein radius θ_E for bound and free-floating planets. We carry out detailed simulations of the planetary events expected in next-generation surveys and estimate the resulting uncertainty in θ_E for these events. We show that, for main-sequence sources and Jupiter-mass planets, the caustic structure of wide-separation planets with projected separations of < 20 AU substantially increases the probability of measuring the dimensionless source size and thus determining θ_E compared to the case of unbound planets. In this limit where the source is much smaller than the caustic, the effective cross-section to measure θ_E to 10% is ~25% larger than the full width of the caustic. Measurement of the lens parallax is possible for low-mass planetary events by combined observations from the ground and a satellite located in an L2 orbit; this would complete the mass measurements for such wide-separation planets. Finally, short-duration events caused by bound planets can be routinely distinguished from those caused by free-floating planets for planet-star separations < 20 AU from either the deviations due to the planetary caustic or (more often) the low-amplitude bump from the magnification due to the parent star.

description: For a large class of variational quantum circuits, we show how arbitrary-order derivatives can be analytically evaluated in terms of simple parameter-shift rules, i.e., by running the same circuit with different shifts of the parameters. As particular cases, we obtain parameter-shift rules for the Hessian of an expectation value and for the metric tensor of a variational state, both of which can be efficiently used to analytically implement second-order optimization algorithms on a quantum computer. We also consider the impact of statistical noise by studying the mean squared error of different derivative estimators. In the second part of this work, some of the theoretical techniques for evaluating quantum derivatives are applied to their typical use case: the implementation of quantum optimizers. We find that the performance of different estimators and optimizers is intertwined with the values of different hyperparameters, such as a step size or a number of shots. Our findings are supported by several numerical and hardware experiments, including an experimental estimation of the Hessian of a simple variational circuit and an implementation of the Newton optimizer.

When sex hurts : couples' experiences of female sexual pain
Creators: name: Hansen, Natalie Mayumi
Publisher: name: University of British Columbia

description: The experience of pain during or after sex is a common and serious phenomenon among women (Laumann, Paik, & Rosen, 1999). Although there is a growing field of literature on this phenomenon, very little of it has shed light on what female sexual pain means for a couple. To meet this need in the literature, the present study was undertaken. The following research question was posed: What are couples' experiences of recurrent physical pain on the part of the female partner during or immediately following sexual contact? In order to best answer the research question, a narrative method was employed. Eight Canadian, heterosexual participants (four men and four women) shared their stories of female sexual pain in individual narrative interviews. The participants chose pseudonyms to be referred by in the narratives. Holistic and thematic analyses (Lieblich, Tuval-Mashiach, & Silber, 1998) revealed contextually different narratives, and across-narrative themes representing common experiences. These experiences were: Adapting to a different sexual relationship, shifts in sexual self-view, challenges to creating a family, difficulties with dealing with medical professionals, and coping. The findings have implications for professionals who work with women and couples experiencing female sexual pain, as well as for future research in this area.

description: The pattern of a matrix M is a (0,1)-matrix which replaces all non-zero entries of M with a 1. A directed graph is said to support M if its adjacency matrix is the pattern of M. If M is an orthogonal matrix, then a digraph which supports M must satisfy a condition known as quadrangularity. We look at quadrangularity in tournaments and determine for which orders quadrangular tournaments exist. We also look at a more restrictive necessary condition for a digraph to support an orthogonal matrix, and give a construction for tournaments which meet this condition.

description: The ionization dynamics of a Xenon cluster with 40 atoms is analyzed under a pum p probe scenario of laser pulses where an infrared laser pulse of 50 fs length follows with a well defined time delay a VUV pulse of the same length and peak intensity. The mechanism of resonant energy absorption due to the coinc idence of the IR laser frequency with the frequency of collective motion of quasi free electrons in the cluster is mapped out by varying the time delay between the pulses.

description: Shapiro time delay is one of the fundamental tests of general relativity and post-Newtonian theories of gravity. Consequently, its measurements can be used to probe the parameter $γ$ which is related to spacetime curvature produced by a unit mass in the post-Newtonian formalism of gravity. To date all measurements of time delay have been conducted on astronomical scales. It was asserted in 2010 that gravitational wave detectors on Earth could be used to measure Shapiro delay on a terrestrial scale via massive rotating systems. Building on that work, we consider how measurements of Shapiro delay can be made using next-generation gravitational wave detectors. We perform an analysis for measuring Shapiro delay with the next-generation gravitational wave detectors Cosmic Explorer and Einstein Telescope to determine how precisely the effect can be measured. Using a rotating mass unit design, we find that Cosmic Explorer and Einstein Telescope can measure the Shapiro delay signal with amplitude signal to noise ratios upwards of $\sim28 $ and $\sim43$ in 1 year of integration time, respectively. By measuring Shapiro delay with this technique, next-generation interferometers will allow for terrestrial measurements of $γ$ in the paramaterized post-Newtonian formalism of gravity with sub-percent precision.

We study subgroups $Γ$ in $\Aff (N)=N\rtimes \Aut (N)$ acting properly discontinuously and cocompactly on N. This situation is a natural generalization of the so-called affine crystallographic groups. We prove that for all dimensions $1\le n\le 5$ the generalized Auslander conjecture holds, i.e., that such subgroups are virtually polycyclic.

 Die Exemplare von H. tectus können nach ihren Merkmalen keinem Gebiet der autochthonen Verbreitung zugeordnet werden. Entsprechend der wirtschaftlichen Verflechtungen und damit Möglichkeiten der Verschleppung bieten sich die Länder Südeuropas (Italien, Griechenland) eher an. H. tectus ist in Südeuropa von Italien bis in den Ägäischen Raum und bis in den Iran verbreitet, vom Kaukasus (locus typicus "Kaukasus", vom Autor nicht näher definiert) nach Westen über den pannonischen Raum bis in den Osten Österreichs verbreitet. Eine rezent isolierte Population in Südtirol, Vinschgau. Die Population in der Schweiz, Wallis, ist verschollen, letzte Funde von Sion, 27.7.1967, ♀, leg. Ebmer.
 Die sehr nahestehende Halictus pulvereus MORAWITZ 1873 von Kleinasien über den Iran, Zentralasien bis in die Mongolei verbreitet, vielleicht westlich bis Griechenland mosaikartig verzahnt. Wegen der sehr geringen taxonomischen Merkmale wären genetische Untersuchungen sinnvoll, über den Status der beiden Taxa mehr zu wissen. Doch H. tectus ist nach den neuesten Erkenntnissen nicht bis in die Mongolei reichend (EBMER 2005b: 368). Das habe ich S. Droege in meinem Brief vom 14.10.2005 ausdrücklich mitgeteilt, aber er hat trotzdem die Verbreitung in seiner Internet-Darstellung wieder "bis in die Mongolei " angegeben.

With the creation of start-up biotech businesses being a very risky pursuit, with capital intensive projects, long product development lead times and regulatory hurdles to overcome, support for such businesses is essential. Business incubators have long been a method of improving start-up success and boosting the local economy. There are, however, many models and metrics for success and some suggestions that in some cases incubators simply keep alive companies that would otherwise not survive. Qualitative interviews were carried out with incubator managers, tenants and partners in the US and China to establish what could be improved in the incubation process, leading to several suggestions for improvements. We found that partnerships with corporate service providers are an underused resource which could provide both revenue for the incubators, network/services for the tenants and boost the local economy with collaborations with tenants enhancing knowledge transfer. Whilst some incubators gained tenants from other incubators or those who had been validated by gaining significant competitive funding, some early-stage incubators had little in the way of selection criteria past being in the local area or being affiliated with the university. We suggest it might also be useful to provide a filtered pipeline or funnel to the physical incubator using a virtual incubator first to allow a coherent team and strategy to be formed before a commitment to paying for physical space, which could increase the quality of tenants and help founders transition from a pure science base to include business skills.
title: Crustal History Indicators on Mercury

Publisher: name: The Open University

description: In this thesis, I investigated curvilinear features on the surface of Mercury and the impact of illumination bias upon observations of those features. I also demonstrated their utility with regard to photostratigraphy and suggest areas where BepiColombo will provide beneficial additional data. Basin-edge scarps occur within volcanically-filled impact basins in all areas of the surface of Mercury. Many large impact basins are filled with Smooth Plains (volcanic) units. I hypothesise that fault nucleation occurs on the mechanically weak interface between the base of the volcanic fill units and the original floor of the impact basin. Using crater size-frequency distribution analysis I have established that resolvable deformation of basin-edge scarps ceased between 1.1 and 0.6 Ga. Based upon location and morphology, I concluded that catenae are likely to be formed by secondary impact ejecta. They are of use when establishing stratigraphic relationships between impact basins, since they extend further away from the primary basin than the ejecta blanket, and tend to remain observable for longer. The stratigraphic map of impact basins Aneirin, Sanai and the immediately surrounding areas demonstrated this, as – despite the basins being the same morphological class (C2) – catenae related to Aneirin were formed after the formation of Sanai. Aneirin is therefore the younger basin. Mercury’s near-zero obliquity means that curvilinear features aligned parallel with the illumination azimuth (east-west at low-mid latitudes) would be likely to be underrepresented in the global population. Using shaded-relief models with alternative artificial illumination to complete resurveys, I found that my global survey of basinedge scarps has been affected. Consequently, I advise the use of shaded-relief models in addition to imagery when mapping curvilinear features. I anticipate that the improved instrumentation of BepiColombo MPO will be invaluable when carrying out stratigraphic mapping and global surveys of specific features such as basin-edge scarps and catenae.

Fachwissenschaftliche Begründungen aus der aktuelleren Säuglingsforschung erweitern das Blickfeld. Mit »Synchronisation« und »Rhythmik« erfahren herkömmliche Interventionsprogramme zur Förderung der Wahrnehmung und des emotional-sozialen Verhaltens eine sinnvolle Ergänzung. Verschiedene Antworten auf die Fragestellungen werden gefunden und diskutiert. Der Ausblick auf mögliche weitere Forschungsthemen schliesst die Arbeit ab.
title: A Cognitive Radio Compressive Sensing Framework
Creators: name: Karampoulas, Dimitrios
Publisher: name: The Open University
Year: 2018

description: With the proliferation of wireless devices and services, allied with further significant predicted growth, there is an ever increasing demand for higher transmission rates. This is especially challenging given the limited availability of radio spectrum, and is further exacerbated by a rigid licensing regulatory regime. Spectrum however, is largely underutilized and this has prompted regulators to promote the concept of opportunistic spectrum access. This allows unlicensed secondary users to use bands which are licensed to primary users, but are currently unoccupied, so leading to more efficient spectrum utilization. A potentially attractive solution to this spectrum underutilisation problem is cognitive radio (CR) technology, which enables the identification and usage of vacant bands by continuously sensing the radio environment, though CR enforces stringent timing requirements and high sampling rates. Compressive sensing (CS) has emerged as a novel sampling paradigm, which provides the theoretical basis to resolve some of these issues, especially for signals exhibiting sparsity in some domain. For CR-related signals however, existing CS architectures such as the random demodulator and compressive multiplexer have limitations in regard to the signal types used, spectrum estimation methods applied, spectral band classification and a dependence on Fourier domain based sparsity. This thesis presents a new generic CS framework which addresses these issues by specifically embracing three original scientific contributions: i) seamless embedding of the concept of precolouring into existing CS architectures to enhance signal sparsity for CR-related digital modulation schemes; ii) integration of the multitaper spectral estimator to improve sparsity in CR narrowband modulation schemes; and iii) exploiting sparsity in an alternative, non-Fourier (Walsh-Hadamard) domain to expand the applicable CR-related modulation schemes. Critical analysis reveals the new CS framework provides a consistently superior and robust solution for the recovery of an extensive set of currently employed CR-type signals encountered in wireless communication standards. Significantly, the generic and portable nature of the framework affords the opportunity for further extensions into other CS architectures and sparsity domains.

description: Die Abstrakte Zustandsmaschine (Abstract State Machine, ASM) ist eine mathematisch basierte formale Methode. In dieser Arbeit wird die Corinthian Abstract State Machine (CASM) Programmiersprache vorgestellt, welche eine konkrete Implementierung einer ASM basierenden Allzweck-Programmiersprache ist. CASM unterstützt das Verschachteln von paralleler und sequenzieller Ausführungssemantik und ist eine statisch getypte Sprache. In dieser Arbeit wird die Laufzeit-Umgebung (Run-Time) und der Codegenerator von CASM vorgestellt, wobei beide Teile auf optimierte Ausführung des erzeugten Programms bezüglich der Ausführungszeit ausgelegt sind. Der Codegenerator erzeugt aus dem CASM Quellcode ein C Programm und die dazugehörige Run-Time ist ebenfalls in C implementiert. Der optimierende Compiler, bestehend aus Codegenerator und Run-Time, beinhaltet zusätzlich ein neues Optimierungs-Framework mit einer speziellen CASM Zwischendarstellung (Intermediate Representation, IR). Basierend auf dieser CASM IR werden verschiedene Analysen und Transformationen in dieser Arbeit beschrieben. Die Evaluierung zeigt, dass CASM gegenüber anderen ASM Implementierungen die Performanteste ist. Die Ergebnisse von Benchmark-Tests zeigen, dass die generierten Programme zwei bis drei Größenordnungen schneller ausgeführt werden als von anderen ASM Implementierungen. Das Optimierungs-Framework und die vorgestellten Transformationen verbessern die Ausführungszeit der generierten Programme noch weiter um den Faktor 2 bis 3.
description: The Abstract State Machine (ASM) is a well known formal method which is based on an algebraic concept. This thesis describes the Corinthian Abstract State Machine (CASM) language which is an implementation of an ASM-based general purpose programming language. Features of this language are its combination of sequential and parallel execution semantics and a statically strong type system. Furthermore, this thesis outlines an optimizing run-time and code generator which enables an optimized execution of CASM programs. The code generator is a CASM to C source-to-source translator and the run-time is implemented in C as well. Moreover the CASM optimizing compiler (run-time and code generator) includes a novel optimization framework with the specialized CASM Intermediate Representation (IR). The CASM IR enables powerful analysis and transformation passes which are presented in detail. The evaluation of this thesis shows that CASM is currently the best performing ASM implementation available. Benchmark results show that the CASM compiler is 2 to 3 orders of magnitude faster than other ASM implementations. Furthermore, the presented optimization passes eliminate run-time costs which increases the execution speed of CASM generated programs by a factor 2 to 3 even further.
title: Roles of the Histone Chaperone FACT in Drosophila Gene Regulation and Chromatin Architecture
Creators: name: Tettey, Theophilus
Publisher: name: The Open University
Year: 2018

description: The highly conserved histone chaperone FACT (Facilitates Chromatin Transcription) is thought to contribute to the disassembly and reassembly of nucleosomes in the wake of RNA polymerase II passage through chromatin. In yeast, mutation of FACT subunits leads to decreased nucleosome occupancy at the promoters and transcribed regions of genes. In addition, genetic experiments suggest that yeast FACT plays a critical role in restricting initiation of transcription to promoters, ensuring that only appropriate mRNAs are synthesized. However, FACT’s roles in chromatin biology and transcriptional regulation in higher eukaryotes are not well understood. Using Drosophila S2 cells as a model, I observe that depleting levels of the FACT complex results in aberrant transcriptional regulation of approximately 20% of expressed genes. We hypothesized that FACT-dependent alterations in transcription occur because nucleosome disassembly and reassembly are defective in FACT deficient S2 cells. To address that hypothesis, I monitored the nucleosome positioning using genome-wide micrococcal nuclease protection assays, and the distribution of bulk histones, histone variants, and histone modifications using ChIP-seq. I observed that FACT depletion has little effect on total nucleosome occupancy or positioning or on the distribution of either the histone variant H2Av or the histone 3 lysine 56 acetylation (H3K56ac) mark. On the other hand, the loss of FACT alters the distribution of other histone modifications, including histone 3 lysine 4 trimethylation (H3K4me3) and histone 3 lysine 36 trimethylation (H3K36me3), in the promoters and transcribed regions of genes. In particular, H3K4me3, a mark of active promoters, was reduced at promoters and increased in gene bodies of the FACT depleted cells. Furthermore, levels of H3K36me3, a mark of active transcription over transcribed regions, was reduced in gene bodies but increased beyond the polyadenylation site. The levels of total (Rpb3) and transcriptionally engaged Pol II (PRO-seq) were reduced at promoters upon the loss of FACT. Taken together, our results are consistent with the model that FACT contributes to the interplay between chromatin architecture and control of promoter-proximal pausing.

description: Electrons and holes are locally injected in a single pentacene monolayer island. The two-dimensional distribution and concentration of the injected carriers are measured by electrical force microscopy. In crystalline monolayer islands, both carriers are delocalized over the whole island. On disordered monolayer, carriers stay localized at their injection point. These results provide insight into the electronic properties, at the nanometer scale, of organic monolayers governing performances of organic transistors and molecular devices.

Processes contributing to optimal preparation and performance of Winter Olympic athletes : the athletes' story
Creators: name: MacNeill, Karen C.
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this investigation was to explore the processes that contribute to optimal preparation and optimal performance of an athlete competing at the Winter Olympic Games. Using narrative methodology, 4 individual sport athletes (2 male, 2 female) who competed at the 2006 Winter Olympic Games in the sports of skeleton, snowboarding, and long track speed skating (one on the all-round team and another on the sprint team) were interviewed using an in-depth, open-ended, semi-structured approach (Rubin & Rubin, 1995). The semi-structured research interview lasted approximately 2-2.5 hours in length, and participants were contacted a second time via email once the data had been analyzed to verify accurate representation of their experience. The qualitative data was analyzed using Lieblich, Tuval-Maschiach, and Zilber (1998) categorical-content narrative analysis approach, which is similar to what is commonly known as content analysis. Narrative accounts, or the athletes' Olympic stories, were also developed through this process. From the narrative analysis, seven themes emerged concerning processes contributing to optimal preparation, and six themes emerged regarding processes contributing to optimal performance. The findings reveal that for optimal preparation of an Olympian, there needs to be development and implementation of a strategic, holistic plan that incorporates processes for balance and recovery, support and mentoring, automating skill and establishing familiarity, and for reflection and monitoring to ensure training potentials are being maximized and that valuable lessons are being extracted. Furthermore, processes contributing to optimal performance at the Olympics require highly functioning self-regulation practices; a level of self-knowledge and self-acceptance that allows detachment from the outcome and freedom to perform authentically; confidence and belief in ability to achieve excellence; perspective, and acceptance and adaptation to current experiences and conditions; focus and engagement in the present moment; and the execution of performance strategies that lead to a high level of performance excellence. Implications for athletes, coaches, and practitioners are discussed, and suggestions for future research are provided.

Hadamard regularization of the third post-Newtonian gravitational wave generation of two point masses

description: Continuing previous work on the 3PN-accurate gravitational wave generation from point particle binaries, we obtain the binary's 3PN mass-type quadrupole and dipole moments for general (not necessarily circular) orbits in harmonic coordinates. The final expressions are given in terms of their ``core'' parts, resulting from the application of the pure Hadamard-Schwartz (pHS) self-field regularization scheme, and augmented by an ``ambiguous'' part. In the case of the 3PN quadrupole we find three ambiguity parameters, xi, kappa and zeta, but only one for the 3PN dipole, in the form of the particular combination xi+kappa. Requiring that the dipole moment agree with the center-of-mass position deduced from the 3PN equations of motion in harmonic coordinates yields the relation xi+kappa=-9871/9240. Our results will form the basis of the complete calculation of the 3PN radiation field of compact binaries by means of dimensional regularization.

Narratives of dissociation : insights into the experience and treatment of dissociation in individuals who have been sexually abused in childhood
Creators: name: Hirakata, Pamela Elizabeth
Publisher: name: University of British Columbia
Year: 2011

description: A narrative research design was used to obtain an in-depth understanding of the experience and treatment of dissociation in seven individuals who had a history of childhood sexual abuse and engaged in moderate to high levels of dissociation. Through a holistic-content analysis (Lieblich, 1998), seven major themes emerged--disconnection to self, others, and the world; gaps in time, space, and memory; the dissociative process; personal meaning and insight; tools and techniques; challenging the dominant paradigm; and the therapeutic relationship. Significant contributions include: (a) redefining dissociation from the perspective of those who dissociate; (b) challenging the dominant discourse that views dissociation through a lens of pathology; and (c) highlighting the critical role of the therapeutic relationship in the treatment of dissociation.

description: In this paper, we introduce the notation of $E$-weighted core-EP and $F$-weighted dual core-EP inverse of matrices. We then obtain a few explicit expressions for the weighted core-EP inverse of matrices through other generalized inverses. Further, we discuss the existence of generalized weighted Moore-Penrose inverse and additive properties of the weighted core-EP inverse of matrices. In addition to these, we propose the star weighted core-EP and weighted core-EP star class of matrices for solving the system of matrix equations. We further elaborate on this theory by producing a few representation and characterization of star weighted core-EP and weighted core-EP star classes of matrices.

title: Inside International Development Organisations: Socially Constructing Judgement in-the-Moment
Creators: name: Vincett, Joanne
Publisher: name: The Open University
Year: 2013

description: This exploratory study aimed, first, to build new knowledge on how senior managers of international development organisations defined judgement and how they made sense of it in the context of their leadership roles and work environments. A secondary aim was to explore methodologies and methods, specifically unstructured interviews and observations, to be used in the PhD phase to study the social phenomenon of judgement. Using an ethnographic and reflexive approach, this study addressed the question: How do managers understand their use of judgement ‘in-the-moment’ in practice? Results from the two participating organisations suggest that there are diverse interpretations of the meaning of ‘judgement’; it is a socially constructed process; used in uncertain situations; and influenced by time and space. These findings contribute to our understanding of how judgement in-the-moment is perceived inside an understudied area: the everyday context of small international development organisations. Theoretically, this study complements the existing literature with a social constructionist perspective and draws linkages to judgement as a constitutive element of sensemaking. Methodologically, the reflexive approach taken builds awareness of examining the ‘multiple selves’ and how researchers influence their research and are influenced by it as subject and object. The validity, methodological issues, limitations and implications for future research are also discussed.

description: Familienorientierung wird in der Heilpädagogischen Früherziehung in der Schweiz als auch international kontrovers diskutiert. Obwohl Familienorientierung ein zentrales Arbeitsprinzip der HFE ist, existiert über die Begrifflichkeit und die Umsetzung in der Praxis keine einheitliche Sichtweise. Diese Arbeit widmet sich dem Spannungsfeld zwischen theoretischen Ansprüchen und realen Anforderungen in der Praxis. Anhand von Interviews mit Fachpersonen der HFE wird deren Verständnis von Familienorientierung, Handlungsansätze und Verbesserungsvorschläge erfragt. Entgegen der Annahme, dass Familienorientierung in der Praxis zu wenig umgesetzt werden könne, stufen die Befragten ihre Arbeit als familienorientiert ein. Inhaltlich wird der Begriff insbesondere als System- und Bedürfnisorientierung verstanden. Dennoch bleibt der Terminus heterogen, die Umsetzung vielfältig. Es besteht der Wunsch nach einer vertieften Auseinandersetzung und Konkretisierung, was Familienorientierung innerhalb der HFE beinhaltet.
Evolution of the role and significance of agriculture for the Polish economy in 1989-2014

description: Socio-economic transformation in the food sector started earlier than in other sectors of the economy, i.e. in the summer of 1989 along with implementation of market solutions. The first period of the transformation was marked by a significant drop in all economic and social indices in agriculture, including a severe drop in the farmers’ income. A change in the status quo began at the turn of the 20th and 21st century. However, only after Poland’s accession to the EU the food sector has started to develop considerably faster. The co-financing of the sector from the national budget and the EU funds fostered a substantial modernisation of agribusiness thus influencing the improvement in the income situation of agricultural producers. As a result of the processes of adjustment to the market conditions and membership in the EU, the size and structure of agricultural production changed significantly. In 2003, after nearly 50 years of a negative balance in foreign trade in agri-food products, Poland became a major player on the world market.
