description: Some euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for centuries. Yet, its function remains controversial, and is even viewed as a functionless ancestral vestige. Here, by examining swimming Euglena gracilis in environments of controlled crowding and geometry, we show that this behaviour is triggered by confinement. Under these conditions, it allows cells to switch from unviable flagellar swimming to a new and highly robust mode of fast crawling, which can deal with extreme geometric confinement and turn both frictional and hydraulic resistance into propulsive forces. To understand how a single cell can control such an adaptable and robust mode of locomotion, we developed a computational model of the motile apparatus of Euglena cells consisting of an active striated cell envelope. Our modelling shows that gait adaptability does not require specific mechanosensitive feedback but instead can be explained by the mechanical self-regulation of an elastic and extended motor system. Our study thus identifies a locomotory function and the operating principles of the adaptable peristaltic body deformation of Euglena cells.

description: The text aims at presenting how to implement a predictive maintenance strategy based on machine learning techniques in an offshore drilling company. Results are related to the execution of the innovation management strategy for an offshore drilling company where the author is employed. After a brief introduction on technology management and different maintenance strategies, the paper focuses on the predictive maintenance topic, in particular on those related to predictive maintenance strategies made available by the Industry 4.0 and technologies such as machine learning. An industry analysis is performed to picture the scenarios within the digital innovation environment in the Oil & Gas, with specific focus on the predictive maintenance and Industry 4.0. A competitor analysis on the digital strategy of the top drilling contractors is then presented. Considering the peculiarities of the Oil and Gas industry, a stakeholder analysis has been carried out in order to allow the reader to understand how the implementation of predictive maintenance strategies can impact the various actors of the business. The methodology used in the subject company to investigate the predictive maintenance technology trend is then presented. The most relevant parameters to implement the predictive maintenance in an offshore drilling contractor, including topics such as supplier selection, technical challenges and potentialities, have been evidenced. Finally, the most relevant parameters to build a business case to justify expenditures on such projects are introduced.

description: We prove that 1+1 and 2+2 target `spacetimes' of a 0-brane are exceptional signatures. Our proof is based on the requirement of SL(2,R) and `Lorentz' symmetries of a first order lagrangian. Using a special kind of 0-brane called `quatl', we also show that the exceptional signatures 1+1 and 2+2 are closely related. Moreover, we argue that the 2+2 target `spacetime' can be understood either as 2+2 worldvolume `spacetime' or as `1+1-matrix-brane'. The possibility that the exceptional 2+2-signature implies an exceptional chirotope is briefly outlined.

description: This article describes a new Stata routine, xtlsdvc, that computes bias-corrected least-squares dummy variable (LSDV) estimators and their bootstrap variance–covariance matrix for dynamic (possibly) unbalanced panel-data models with strictly exogenous regressors. A Monte Carlo analysis is carried out to evaluate the finite-sample performance of the bias-corrected LSDV estimators in comparison to the original LSDV estimator and three popular N-consistent estimators: Arellano–Bond, Anderson–Hsiao and Blundell–Bond. Results strongly support the bias-corrected LSDV estimators according to bias and root mean squared error criteria when the number of individuals is small.

description: The topic of this master thesis is corporate foresight with a focus on the multiple perspectives of a strategic foresight process within a company to create and maintain a high-quality forward view. Especially in a fast-changing world with uncertainty and discontinuous change, the foresight process of identifying upcoming future impacts gets more and more attention. The aim of this thesis is to give an overview about foresight in general, to dive into the depth of corporate foresight and describing the foresight 2.0 systems and the related foresight support systems. However, small to mid-size companys sometimes struggle with a clear approach on corporate foresight within the company, particularly when different departments have to align their forward view to create value out of the corporate foresight process. The research questions focus on who does foresight, with which tools and which outcome within one company and how can new technologies support in this process. How this process works out in a mid-size company in the chemical industry is finally described, evaluated and critically discussed.

description: The structure and the properties of complex networks essentially depend on the way how nodes get connected to each other. We assume here that each node has a feature which attracts the others. We model the situation by assigning two numbers to each node, ωand α, where ωindicates some property of the node and αthe affinity towards that property. A node A is more likely to establish a connection with a node B if B has a high value of ωand A has a high value of α. Simple computer simulations show that networks built according to this principle have a degree distribution with a power law tail, whose exponent is determined only by the nodes with the largest value of the affinity α(the "extremists"). This means that the extremists lead the formation process of the network and manage to shape the final topology of the system. The latter phenomenon may have implications in the study of social networks and in epidemiology.

description: We review the quantum theory of a single spin magnetic resonance force microscopy (MRFM). We concentrate on the novel technique called oscillating cantilever-driven adiabatic reversals (OSCAR), which has been used for a single spin detection (Dan Rugar, Talk on the 2004 IEEE NTC Quantum Device Technology Workshop). First we describe the quantum dynamics of the cantilever-spin system using simple estimates in the spirit of the mean field approximation. Then we present the results of our computer simulations of the Schrodinger equation for the wave function of the cantilever-spin system and of the master equation for the density matrix of the system. We demonstrate that the cantilever behaves like a quasi-classical measurement device which detects the spin projection along the effective magnetic field. We show that the OSCAR technique provides continuous monitoring of the single spin, which could be used to detect the mysterious quantum collapses of the wave function of the cantilever-spin system.

description: To obtain the explicit form of evolution operator in the Tavis-Cummings model we must calculate the term ${e}^{-itg(S_{+}\otimes a+S_{-}\otimes a^{\dagger})}$ explicitly which is very hard. In this paper we try to make the quantum matrix $A\equiv S_{+}\otimes a+S_{-}\otimes a^{\dagger}$ diagonal to calculate ${e}^{-itgA}$ and, moreover, to know a deep structure of the model. For the case of one, two and three atoms we give such a diagonalization which is first nontrivial examples as far as we know, and reproduce the calculations of ${e}^{-itgA}$ given in quant-ph/0404034. We also give a hint to an application to a noncommutative differential geometry. However, a quantum diagonalization is not unique and is affected by some ambiguity arising from the noncommutativity of operators in quantum physics. Our method may open a new point of view in Mathematical Physics or Quantum Physics.

The Concept of Fact in German Physics around 1900: A Comparison between Mach and Einstein

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)

description: The concept of fact has a history. Over the past centuries, physicists have appropriated it in various ways. In this article, we compare Ernst Mach and Albert Einstein's interpretations of the concept. Mach, like most nineteenth-century physicists, contrasted fact and theory. He understood facts as real and complex combinations of natural events. Theories, in turn, only served to order and communicate facts efficiently. Einstein's concept of fact was incompatible with Mach's, since Einstein believed facts could be theoretical too, just as he ascribed mathematical theorizing a leading role in representing reality. For example, he used the concept of fact to refer to a generally valid result of experience. The differences we disclose between Mach and Einstein were symbolic for broader tensions in the German physics discipline. Furthermore, they underline the historically fluid character of the category of the fact, both within physics and beyond.

description: I describe a command that simultaneously solves the extended estimating equations estimator for parameters in the link and variance functions along with those of the linear predictor in a generalized linear model. The method addresses difficulties in choosing the correct link and variance functions in these models. It decouples the scale of estimation for the mean model, determined by the link function, from the scale of interest for the scientifically relevant effects. It also estimates a flexible variance structure from the data, leading to efficient estimation.

description: Пренатальное воздействие ганглероном и в меньшей степени метамизилом приводит к значительным нарушениям мотивационного компонента половой функции у половозрелых потомств самцов, выражающихся в низких значениях проявления первичной половой активности, и увеличения латентости подхода и половой дисфункции после приобретения полового опыта. Среди причин нарушения половой функции у потомства можно отметить изменение гормонального фона у самцов крыс в виде значительного снижения уровня основного андрогена тестостерона, а также повреждение дофаминергических систем мозга, проявляющееся в снижении уровня дофамина. Результаты эндокринных исследований свидетельствуют об изменении гормонального фона у самцов крыс в виде значительного снижения уровня основного андрогена Тс, что является одной из причин нарушения половой функции у потомств. Пренатальная экспорзиция холинотропным препаратам завершается альтерациями дофаминергических систем мозга у 20-дневных плодов крыс и у 2-месячных потомств, которые вовлечены в этиопатогенез поведенческих нарушений в пубертатном периоде.

description: This master thesis examines questions around a new kind of strategy development and implementation for established, traditional and not particularly agile companies as they face new challenges in the future. Due to the accelerated changes regarding market, competitors, customer behavior and technology, many companies have trouble finding a strategy to be successful in the future - or simply to survive. This Master's thesis should be an approximation to a new way in overall strategy through an agile focus strategy approach. The framework "Business Model Navigator" by Marc Gruber and Sharon Tal will be taken as a starting point, however adapted and supplemented for the needs of established companies. The difficulties to recognize and analyze the core competencies detached from possible applications of a company, will be discussed in order to build a strategy on those. A radical shift in strategy means an enormous change process for a large company and is not easy to manage. Hierarchical barriers and a strong desire for security and control have to be overcome. For this reason, a possible process is presented that would serve a successful transformation process. The research questions aim at the combination of existing tools and methods to model an agile focus strategy in traditional business setups while also adressing the change process itself. Within a large Swiss retail bank, the need for an agile focus strategy and the model will be validated through qualitative interviews and the evaluation of existing documents. Further challenges in the area of a sustainable overall strategy will be identified and concrete obstructions in the transformation process will be identified. The necessity and the need for a new model for the development and implementation of a strategy exists, especially because the established processes erode over time and do not fulfill the desired ambitions. This work aims to contribute to the discussion about innovation in strategy and management and to rethink traditional strategy processes in top management.

description: The Buckley–James method and the Cox proportional hazards model were proposed in the 1970s. Both methods can be used to analyze survival-type data, although the former focuses on calculation of the expected value of the survival time and the latter on the relative risk of explanatory variables on the failure event. In cardiovascular disease epidemiological studies, it is essential to correct the effect of taking antihypertensive medicine, which means we need to calculate the expected blood pressure for people who take the medicine. I developed a Stata program to calculate the Buckley–James estimate. I will describe how to use this program to calculate the expected value of a censored outcome and illustrate the method through an example from a cardiovascular disease and an HIV/AIDS study.
Small-area disability-adjusted life years : a new approach to the spatio-temporal analysis of public health surveillance data
Creators: name: Lima, Viviane Dias
Publisher: name: University of British Columbia
Year: 2009

description: When engaged in injury surveillance and regional health planning (e.g., the allocation and distribution of health services and prevention initiatives) it is essential that the health status of regions be monitored over time. The conventional approach to monitoring the health impact of injuries has been to summarize the spatial variation of each region using measures such as mortality and incidence rates. While the use of such measures yields important surveillance information, it does not directly quantify the overall (i.e., fatal and non-fatal) injury burden experienced by individual communities. Although measures of incidence and burden can be derived for small regions, they are often based on a low number of observed injury cases. These low counts are frequently associated with high degrees of chance variation. Recently developed model-based disease mapping methods reduce the influence of chance variation and in so doing yield more reliable estimates of the underlying variation in injury incidence and burden. In this thesis we describe how estimates of disability-adjusted life years (DALY) can be integrated into spatio-temporal Bayesian statistical methods to quantitatively describe how the burden of injuries varies between and within regions of British Columbia (BC) over time. As a demonstration, we examined administrative hospitalization data using the DALY methodology to calculate the incidence and burden of 13 external causes of injury at the provincial and health authority level from 1991-2000. To illustrate the small-area analysis of injury burden, we used the same data to describe the impact of road traffic accidents. Lastly, we examined injuries due to adverse events to demonstrate the usefulness of administrative database screening to describe region-specific impacts of these injuries in BC. Obtaining reliable small-area DALY estimates has the potential to dramatically improve our understanding of public health problems. As shown in this thesis, this methodology enables researchers to quantify the total number of healthy years lost for leading causes of injury. In addition to scientific gains, this information can be used to inform the setting of regional priorities related to the planning and delivery of health care and quantify the benefits of regional intervention programs in cost-effectiveness analyses.

description: Scaling social entrepreneurship is widely recognized as being vital to meet crucial goals for our society, yet current efforts are falling short and therefore different approaches need to be considered. Amongst the intermediary organizations that have recently started to support the scaling efforts of social entrepreneurs, there are some innovative organisations that are approaching the challenge differently by focusing on the effective demand side (clear problem definition and need) and helping social ventures to scale by matching that demand through replication of their solutions. However, little is known about their work, suggesting a need for further investigation into their practices and success factors. This thesis explores this emerging phenomenon through a literature review, background research on these intermediaries and an analysis of qualitative data from interviews with them. Findings suggest that these successful scaling intermediaries share commonalities in their approach of having a strong emphasis on problem definition and establishing ‘effective demand, connecting this successfully with proven supplyside solutions, whilst meanwhile finding ways to engage the right people to overcome initial cynicism and resistance to change in order to deliver systemic change. Results contribute to prior research on scaling and replication of social entrepreneurship by acknowledging the role of these scaling support intermediaries in the ecosystem and identifying best practices and approaches. Findings also highlight the importance of continuous learnings and suggest that enhanced sharing of process learnings and partnerships between intermediaries could unlock significant potential within the social entrepreneurship sector. The results of this thesis are therefore relevant for social entrepreneurs, intermediaries and funders in the social impact economy, and researchers in the field of social entrepreneurship as this shows an exciting opportunity for disruption with the potential to make significant impact.

description: The aim of this master thesis is to propose a general framework that facilitates the implementation of neural networks in the manufacturing industry and beyond. The process steps described in this framework provide a structured approach and serve as a guide if neural networks are considered to be implemented in an industrial setting. Furthermore, having and following this approach not only saves time as there is a risk of overlooking certain steps, which then need to be reconsidered, but can also increase the accuracy of the model itself. Moreover, a key point of this thesis is the question, when and for which problems state-of-theart artificial neural networks can be applied in manufacturing. To answer this, first an extensive review of recent academic literature was conducted. Secondly, an analysis was performed, which includes the qualitative assessment of two recent use-cases of neural networks used in a manufacturing context. Based on the findings of the literature review as well as the qualitative assessment a general framework was derived. In order to prove the usability of this framework was used to self-develop a neural network application solving an existent problem in supply chain management and procurement, specifically the prediction of whether a delivery of goods will be on time or late. Subsequently, the performance of the network and its prediction accuracy were validated. Indeed, it was observed that neural networks are most suitable for solving regression and classification problems, whereas for manufacturing the focus is on classification problems. In addition, a general framework was derived which was also used to self-develop a neural network. This neural network was not only able to solve the underlying problem of predicting and classifying on time or late deliveries of goods, but also achieved a performance measured by binary accuracy of 0.82, a validation accuracy for on time deliveries of 0.82 and a validation accuracy for late deliveries of 0.72.

description: We present calculations for electronic and magnetic properties of surface states confined by a circular quantum corral built of magnetic adatoms (Fe) on a Cu(111) surface. We show the oscillations of charge and magnetization densities within the corral and the possibility of the appearance of spin--polarized states. In order to classify the peaks in the calculated density of states with orbital quantum numbers we analyzed the problem in terms of a simple quantum mechanical circular well model. This model is also used to estimate the behaviour of the magnetization and energy with respect to the radius of the circular corral. The calculations are performed fully relativistically using the embedding technique within the Korringa-Kohn-Rostoker method.

description: The objective of this master thesis is to investigate potential business models for Mission Critical Communications (MCC), taking into consideration evolving user organisation requirements requiring high speed data, spectrum limitations, current mobile broadband functionality and performance issues which make partnerships with commercial Mobile Network Operators an attractive option. At the time of writing, most MCC networks are owned by user organisations and operated as a managed service by subsidiaries of, or consortiums made up of telecommunications manufacturers and local partners, if not operated by the user organisation themselves. Mobile broadband offers high data rates but operates on higher frequencies and lower transmission power settings than existing MCC systems, therefore requiring considerably more network infrastructure for similar performance. For most MCC user organisations that require ubiquitous coverage, the cost of owning a dedicated broadband network is prohibitive and therefore partnerships with commercial Mobile Network providers or other options have to be considered. User requirements are examined, potential service delivery frameworks analysed and appropriate business models are evaluated. Hybrid models are examined and the relative merits of the various delivery frameworks and business models are evaluated from the user organisation and operator perspectives. Focusing on the managed service model, the tendering process is investigated and methods to fulfil user requirements and demonstrate this competence as a presales activity are discussed. Methods of maintaining superior customer satisfaction, executive and operational, are analysed while KPIs to be monitored and measures taken to retain customers once the service is running are developed.

description: Simpler encoding and decoding networks are necessary for more reliable quantum error correcting codes (QECCs). The simplification of the encoder-decoder circuit for a perfect five-qubit QECC can be derived analytically if the QECC is converted from its equivalent one-way entanglement purification protocol (1-EPP). In this work, the analytical method to simplify the encoder-decoder circuit is introduced and a circuit that is as simple as the existent simplest circuits is presented as an example. The encoder-decoder circuit presented here involves nine single- and two-qubit unitary operations, only six of which are controlled-NOT (CNOT) gates.

description: We investigate the relation between the detection of the $11.3\,μ$m PAH feature in the nuclear ($\sim 24-230\,$pc) regions of 22 nearby Seyfert galaxies and the properties of the cold molecular gas. For the former we use ground-based (0.3-0.6" resolution) mid-infrared (mid-IR) spectroscopy. The cold molecular gas is traced by ALMA and NOEMA high (0.2-1.1") angular resolution observations of the CO(2-1) transition. Galaxies with a nuclear detection of the $11.3\,μ$m PAH feature contain more cold molecular gas (median $1.6\times 10^7\,M_\odot$) and have higher column densities ($N({\rm H}_2) = 2 \times 10^{23}\,{\rm cm}^{-2}$) over the regions sampled by the mid-IR slits than those without a detection. This suggests that molecular gas plays a role in shielding the PAH molecules in the harsh environments of Seyfert nuclei. Choosing the PAH molecule naphthalene as an illustration, we compute its half-life in the nuclear regions of our sample when exposed to 2.5keV hard X-ray photons. We estimate shorter half-lives for naphthalene in nuclei without a $11.3\,μ$m PAH detection than in those with a detection. The Spitzer/IRS PAH ratios on circumnuclear scales ($\sim$ 4" $\sim$ 0.25-1.3kpc) are in between model predictions for neutral and partly ionized PAHs. However, Seyfert galaxies in our sample with the highest nuclear H$_2$ column densities are not generally closer to the neutral PAH tracks. This is because in the majority of our sample galaxies, the CO(2-1) emission in the inner $\sim$ 4" is not centrally peaked and in some galaxies traces circumnuclear sites of strong star formation activity. Spatially resolved observations with the MIRI medium-resolution spectrograph (MRS) on the James Webb Space Telescope will be able to distinguish the effects of an active galactic nucleus (AGN) and star formation on the PAH emission in nearby AGN.

description: In this work, we demonstrate a discrete dispersion scan scheme using a low number of flat windows to vary the dispersion of laser pulses in discrete steps. Monte Carlo simulations indicate that the pulse duration can be retrieved accurately with less than 10 dispersion steps, which we verify experimentally by measuring few-cycle pulses and material dispersion curves at 3 and 10 micrometer wavelength. This minimal measuring scheme using only five optical components without the need for high-precision positioners and interferometric alignment can be readily implemented in many wavelength ranges and situations.

description: I first give a brief overview of the status of exotic hadron search so far. Then I review the recent theoretical development on pentaquarks. Finally I emphasize that none of theoretical formalisms predicts the existence of $Θ$ pentaquark very reliably. None of them explains its narrow width in a natural way.

description: In the first step, experiments on a single cerium or ytterbium Kondo impurity reveal the importance of the Kondo temperature by comparison to other type of couplings like the hyperfine interaction, the crystal field and the intersite coupling. The extension to a lattice is discussed. Emphasis is given on the fact that the occupation number $n_f$ of the trivalent configuration may be the implicit key variable even for the Kondo lattice. Three $(P, H, T)$ phase diagrams are discussed: CeRu$_2$Si$_2$, CeRhIn$_5$ and SmS.

description: Legal Tech and Artificial Intelligence are often used as buzz words to promote new products that allegedly have the potential to disrupt the entire legal industry. However, the reality of many Austrian lawyers is different. So far most Legal Tech tools only facilitate administrative tasks or support lawyers in simple repetitive legal tasks. The most commonly used tools dont even involve Artificial Intelligence. Already since the 1950s Artificial Intelligence has been the subject of regular scientific research and greater progress has been announced ever since. So why should there be break throughs now and what can the combination of these two fields achieve? The aim of this master thesis is to critically evaluate potential fields of application of Artificial Intelligence in Legal Tech for lawyers, companies and the public sector. The thesis will give examples in all three areas where and how Artificial Intelligence is already used today and assess the conditions for progressing use of Artificial Intelligence in Legal Tech. Further, problems and implications arising from the use of Artificial Intelligence shall be evaluated. In order to give a future outlook, this master thesis will analyze the abilities and properties required, whether humans or Artificial Intelligence can perform better in these domains and look at potential improvements to the status quo by Artificial Intelligence. The Thesis finds that Artificial Intelligence will enable lawyers to focus on more complex legal work and offer new opportunities, whereas it will also affect their education and pricing models and increase competition. The public sector will also increasingly work with AI, but constitutional rights and those of the GDPR will have to be respected. Finally, new opportunities for businesses will arise.

description: paper studies managerial and entrepreneurial aspects of pre-entry market opportunity identification and strategic market choice, with special reference to new frameworks available in this area and their relevance to innovation management. New and ground-breaking research discoveries in the theoretical background of this field have enabled the creation of new strategic tools which are developed for and aimed at entrepreneurs, strategy professionals, managers, venture capitalists and investment professionals. In doing so, the Market Opportunity Navigator (Gruber & Tal, 2017a) builds a bridge between the theory of and practice in the field. Analyzing and observing empirically how market opportunity identification is conducted presently, the paper further seeks potential factors that may hinder the adoption of such frameworks as part of the overall strategy development process. To this end, an interviewbased qualitative study of fifteen high-level strategy practitioners is conducted to add further insights of how such frameworks are adapted and employed in practice. A Swiss drone technology startup is used as a case study for the successful application of the mentioned pre-entry market opportunity identification tools. Further, looking at large enterprises, a second empirical study of ten of the largest automotive companies in the world is conducted, exploring whether market choice is regarded as part of their strategic outlook. Methodologically, both the interviews and the large company study are based on the principles of qualitative content analysis, according to Mayring (2011). The study aims to add a new perspective of practitioners use of the recent market opportunity identification frameworks to the growing body of knowledge and debate in this field.
Magnon bands in twisted bilayer honeycomb quantum magnets

description: We study the magnon bands of twisted bilayer honeycomb quantum magnets using linear spin wave theory. Although the interlayer coupling can be ferromagnetic or antiferromagnetic, we keep the intralayer one ferromagnetic to avoid possible frustration. For the interlayer ferromagnetic case, we find the magnon bands have similar features with the corresponding electronic energy spectrums. Although the linear dispersions near the Dirac points are preserved in the magnon bands of twisted bilayer magnets, their slopes are graduately reduced with the decrease of the twist angles. On the other hand, the interlayer antiferromagnetic couplings generate quite different magnon spectra. The two single-layered magnon spectra are usually undecoupled due to the opposite orientations of the spins in the two layers. We also develop a low-energy continuous theory for very small twist angles, which has been verified to fit well with the exact tight-binding calculations. Our results may be experimentally observed due to the rapid progress in two-dimensional magnetic materials.
