description: Many real world problems can be expressed as optimisation problems. Solving this kind of problems means to find, among all possible solutions, the one that maximises an evaluation function. One approach to solve this kind of problem is to use an informed search strategy. The principle of this kind of strategy is to use problem-specific knowledge beyond the definition of the problem itself to find solutions more efficiently than with an uninformed strategy. This kind of strategy demands to define problem-specific knowledge (heuristics). The efficiency and the effectiveness of systems based on it directly depend on the used knowledge quality. Unfortunately, acquiring and maintaining such knowledge can be fastidious. The objective of the work presented in this paper is to propose an automatic knowledge revision approach for systems based on an informed tree search strategy. Our approach consists in analysing the system execution logs and revising knowledge based on these logs by modelling the revision problem as a knowledge space exploration problem. We present an experiment we carried out in an application domain where informed search strategies are often used: cartographic generalisation.

description: Loewner's equation provides a way to encode a simply connected domain or equivalently its uniformizing conformal map via a real-valued driving function of its boundary. The first main result of the present paper is that the Dirichlet energy of this driving function (also known as the Loewner energy) is equal to the Dirichlet energy of the log-derivative of the (appropriately defined) uniformizing conformal map.
 This description of the Loewner energy then enables to tie direct links with regularized determinants and Teichmüller theory: We show that for smooth simple loops, the Loewner energy can be expressed in terms of the zeta-regularized determinants of a certain Neumann jump operator. We also show that the family of finite Loewner energy loops coincides with the Weil-Petersson class of quasicircles, and that the Loewner energy equals to a multiple of the universal Liouville action introduced by Takhtajan and Teo, which is a Kähler potential for the Weil-Petersson metric on the Weil-Petersson Teichmüller space.

description: Purpose: To identify the most informative methods for reporting results of treatment planning comparisons. Methods: Seven papers from the past year of International Journal of Radiation Oncology Biology Physics reported on comparisons of treatment plans for IMRT and IMAT. The papers were reviewed to identify methods of comparisons. Decision theoretical concepts were used to evaluate the study methods and highlight those that provide the most information. Results: None of the studies examined the correlation between objectives. Statistical comparisons provided some information but not enough to make provide support for a robust decision analysis. Conclusion: The increased use of treatment planning studies to evaluate different methods in radiation therapy requires improved standards for designing the studies and reporting the results.
Progranulin (PGRN) functions in neuronal cultures

Publisher: name: University of British Columbia
Year: 2009

description: Null mutations in the progranulin gene (PGRN) have been identified as a major cause of frontotemporal lobe dementia with ubiquitinated inclusions (FTLD-U). In this disorder, the ubiquitinated aggregated protein inclusions of a normally nuclear-located RNA processing protein called TAR DNA binding protein (TDP-43) accumulate in the cytoplasm of neurons. To determine whether aspects of this clinical pathology can be established in primary cultures of mouse cortical neurons, PGRN levels were knocked down in cultures using lentiviral vectors to introduce siRNA constructs. Similar to observations in the brains of FTLD-U patients, TDP-43 levels were markedly decreased in the nucleus of PGRN knockdown neurons relative to cytoplasmic levels in comparison to control neurons and significantly recovered by over-expressed PGRN, although the TDP-43 cleavage was not obvious in this model. Meanwhile, depletion of PGRN elevated levels of activated caspase-3, and the PGRN-deficient neurons demonstrated enhanced vulnerability to sub-lethal doses of NMDA and H₂O₂. These results show that it is possible to recapitulate key features of the PGRN null mutation in a culture dish within a short period of time and suggest that the seeds of this form of frontotemporal dementia may be sown early in life.

description: We have obtained spectroscopic observations of the nebulae around seven Wolf-Rayet (WR) stars, four in the Milky Way (WR 8, 16, 18 and 40) and three in the LMC (BAT99-2, -11 and -38). They were observed using the ESO NTT with the EFOSC-2 instrument, except for one nebula, NGC 3199, which was observed using the UVES echelle spectrometer on the VLT. The aims of these observations were to (a) quantify the degree of chemical enrichment in WR nebulae which had previously been suggested to have abundances reflecting nucleosynthetic processing; and (b) to attempt to detect the far-red lines of neutral carbon (e.g. [C I] 9850A) in the nebulae around WC stars. Nebular densities, temperatures and elemental abundances were derived using standard emission line diagnostics. Our high spectral resolution UVES dataset for NGC 3199 allowed the determination of line broadening temperatures using lines from several different species. These showed consistent patterns and fair agreement with the nebular temperatures derived from diagnostic line ratios. Amongst the Galactic WR nebulae, the nebulae around WR 8, 16 and 40 were found to be strongly nitrogen-enriched while NGC 3199 displayed abundances which were similar to those of Galactic H II regions. Amongst the LMC WR nebulae, none displayed an N/O ratio that significantly exceeded LMC H II region values. The far-red [C I] lines were detected from NGC 3199, with the strength of the 8727A line indicating that at least part of it was produced by C+ recombination rather than collisional excitation. The line widths of the [C I] 9824 and 9850A lines were however the same as those of collisionally excited nebular lines, indicating that those lines originated largely from ionized regions within the nebula.

description: Neben seinen Vorteilen führt das Rührreibschweißen mit dem Doppelschulterwerkzeug zu erhöhtem Wärmeeintrag und somit zur Verschlechterung der mechanischen Eigenschaften der Verbindung. Neue Schweißwerkzeuge und ein neues Handhabungssystem wurden entwickelt. Ein analytisches Modell wurde eingeführt, welches die kinetische Energie des Materialflusses auf der Gegenlaufseite in der numerischen Simulation als kritische Größe für die experimentelle Durchführbarkeit erkennt. In Versuchen zeigte das neue semi-stationäre Doppelschulterwerkzeug geringere Reaktionskräfte in Kombination mit Schweißgeschwindigkeiten von 3000 mm/min bei reduziertem Wärmeeintrag. Mit diesem neuen Werkzeugkonzept erscheint der Einsatz von Knickarmrobotern als realistisch.
description: Next to the advantages, in Bobbin Tool Friction Stir Welding (BT-FSW) the excessive heat generated by both shoulders leads to an excessive degradation of the joint microstructure and a consequent loss in mechanical properties. During this work a new set of welding tools and a new unique experimental BT-FSW system was created. An analytical model was introduced, which identified the kinetic energy on the retreating side of the weld zone as a critical value in the modelling to indicate the experimental feasibility. The Semi-Stationary Bobbin Tool (S3BT) process variant has shown good results in reducing handling forces in combination with considerable high welding speeds of 3000 mm/min and low energy inputs. The adaption of the tool concept to articulated arm robots appears realistic.

description: In earlier work of the author rigid irregular connections with differential Galois group $G_2$ and whose slopes have numerator $1$ were classified and new rigid connections were constructed. The same construction can be carried out for $\ell$-adic local systems in the setting of positive characteristic. In this article we provide the results that are needed to obtain the classification of wildly ramified rigid $G_2$-local systems whose slopes have numerator $1$. The overall strategy of the classification is very similar but the methods needed to obtain some invariants differ.

description: The research questions that motivate transportation safety studies are causal in nature. Safety researchers typically use observational data to answer such questions, but often without appropriate causal inference methodology. The field of causal inference presents several modeling frameworks for probing empirical data to assess causal relations. This paper focuses on exploring the applicability of two such modeling frameworks---Causal Diagrams and Potential Outcomes---for a specific transportation safety problem. The causal effects of pavement marking retroreflectivity on safety of a road segment were estimated. More specifically, the results based on three different implementations of these frameworks on a real data set were compared: Inverse Propensity Score Weighting with regression adjustment and Propensity Score Matching with regression adjustment versus Causal Bayesian Network. The effect of increased pavement marking retroreflectivity was generally found to reduce the probability of target nighttime crashes. However, we found that the magnitude of the causal effects estimated are sensitive to the method used and to the assumptions being violated.

description: We consider closed-form approximations for European put option prices within the Heston and GARCH diffusion stochastic volatility models with time-dependent parameters. Our methodology involves writing the put option price as an expectation of a Black-Scholes formula and performing a second-order Taylor expansion around the mean of its argument. The difficulties then faced are simplifying a number of expectations induced by the Taylor expansion. Under the assumption of piecewise-constant parameters, we derive closed-form pricing formulas and devise a fast calibration scheme. Furthermore, we perform a numerical error and sensitivity analysis to investigate the quality of our approximation and show that the errors are well within the acceptable range for application purposes. Lastly, we derive bounds on the remainder term generated by the Taylor expansion.

description: Quantification and classification of protein structures, such as knotted proteins, often requires noise-free and complete data. Here, we develop a mathematical pipeline that systematically analyses protein structures. We showcase this geometric framework on proteins forming open-ended trefoil knots, and we demonstrate that the mathematical tool, persistent homology, faithfully represents their structural homology. This topological pipeline identifies important geometric features of protein entanglement and clusters the space of trefoil proteins according to their depth. Persistence landscapes quantify the topological difference between a family of knotted and unknotted proteins in the same structural homology class. This difference is localized and interpreted geometrically with recent advancements in systematic computation of homology generators. The topological and geometric quantification we find is robust to noisy input data, which demonstrates the potential of this approach in contexts where standard knot theoretic tools fail.

description: Semiclassical behavior of Stark resonances is studied. The complex distortion outside a cone is introduced to study resonances in any energy region for the Stark Hamiltonians with non-globally analytic potentials. The non-trapping resolvent estimate is proved by the escape function method. The Weyl law and the resonance expansion of the propagator are proved in the shape resonance model. To prove the resonance expansion theorem, the functional pseudodifferential calculus in the Stark effect is established, which is also useful in the study of the spectral shift function.

Diese Steigerung hängt aber stark von den Eigenschaften des Funkkanals ab, die in Simulationsmodellen passend abgebildet werden müssen. In dieser Arbeit wird ein neues MIMO-Kanalmodell entwickelt. Die Leistungsfähigkeit von bekannten MIMO-Techniken wird in Simulationen mit konventionellen Kanalmodellen und dem neu entwickelten ausgewertet. Die mögliche Leistungssteigerung durch MIMO-Techniken und deren Grenzen wird anhand des neuen Kanalmodells erläutert.
description: Future radio communication systems with more than one antenna (Multiple Input Multiple Output, MIMO) promise to improve the data rate dramatically. This potential improvement depends strongly on the properties of the radio channel, which need to be modeled appropriately for simulation purposes. In this thesis, a new multi-antenna radio channel model will be developed. Commonly proposed MIMO techniques will be introduced and their performance will be simulated in conventional channel models and in the newly developed one. The possible performance improvement due to MIMO and its limitations will be explained using the new radio channel model.

description: We report the development and performance of on-chip interconnects designed to suppress electromagnetic (EM) crosstalk in spin qubit device architectures with the large number of gate electrodes needed for multi- qubit operation. Our design improves the performance of typical device interconnects via the use of minia- turised ohmic contacts and interspersed ground guards. Low temperature measurements and numerical simulation confirm that control and readout signal crosstalk can be suppressed to levels of order 1%, from dc to 1 GHz.

DNA nucleotide-specific modulation of μA transverse edge currents through a metallic graphene nanoribbon with a nanopore

description: We propose two-terminal devices for DNA sequencing which consist of a metallic graphene nanoribbon with zigzag edges (ZGNR) and a nanopore in its interior through which the DNA molecule is translocated. Using the nonequilibrium Green functions combined with density functional theory, we demonstrate that each of the four DNA nucleotides inserted into the nanopore, whose edge carbon atoms are passivated by either hydrogen or nitrogen, will lead to a unique change in the device conductance. Unlike other recent biosensors based on transverse electronic transport through DNA nucleotides, which utilize small (of the order of pA) tunneling current across a nanogap or a nanopore yielding a poor signal-to-noise ratio, our device concept relies on the fact that in ZGNRs local current density is peaked around the edges so that drilling a nanopore away from the edges will not diminish the conductance. Inserting a DNA nucleotide into the nanopore affects the charge density in the surrounding area, thereby modulating edge conduction currents whose magnitude is of the order of μA at bias voltage ~ 0.1 V. The proposed biosensor is not limited to ZGNRs and it could be realized with other nanowires supporting transverse edge currents, such as chiral GNRs or wires made of two-dimensional topological insulators.

description: Background: L-kynurenine is a tryptophan-derived immunosuppressive metabolite and precursor to neurotoxic anthranilate and quinolinate. We evaluated the stereoisomer D-kynurenine as an immunosuppressive therapeutic which is hypothesized to produce less neurotoxic metabolites than L-kynurenine. Methods: L-/D-kynurenine effects on human and murine T cell function were examined in vitro and in vivo (homeostatic proliferation, colitis, cardiac transplant). Kynurenine effects on T cell metabolism were interrogated using [13C] glucose, glutamine and palmitate tracing. Kynurenine was measured in tissues from human and murine tumours and kynurenine-fed mice. Findings: We observed that 1 mM D-kynurenine inhibits T cell proliferation through apoptosis similar to L-kynurenine. Mechanistically, [13C]-tracing revealed that co-stimulated CD4+ T cells exposed to L-/D-kynurenine undergo increased β-oxidation depleting fatty acids. Replenishing oleate/palmitate restored effector T cell viability. We administered dietary D-kynurenine reaching tissue kynurenine concentrations of 19 μM, which is close to human kidney (6 μM) and head and neck cancer (14 μM) but well below the 1 mM required for apoptosis. D-kynurenine protected Rag1-/- mice from autoimmune colitis in an aryl-hydrocarbon receptor dependent manner but did not attenuate more stringent immunological challenges such as antigen mismatched cardiac allograft rejection. Interpretation: Our dietary kynurenine model achieved tissue concentrations at or above human cancer kynurenine and exhibited only limited immunosuppression. Sub-suppressive kynurenine concentrations in human cancers may limit the responsiveness to indoleamine 2,3-dioxygenase inhibition evaluated in clinical trials.

description: The formation of amplitude modulated and phase modulated assemblies of neurons is observed in the brain functional activity. The study of the formation of such structures requires that the analysis has to be organized in hierarchical levels, microscopic, mesoscopic, macroscopic, each with its characteristic space-time scales and the various forms of energy, electric, chemical, thermal produced and used by the brain. In this paper, we discuss the microscopic dynamics underlying the mesoscopic and the macroscopic levels and focus our attention on the thermodynamics of the non-equilibrium phase transitions. We obtain the time-dependent Ginzburg-Landau equation for the non-stationary regime and consider the formation of topologically non-trivial structures such as the vortex solution. The power laws observed in functional activities of the brain is also discussed and related to coherent states characterizing the many-body dissipative model of brain.

description: Verbindungskonzepte, die traditionell für den Verbinden von Metall-Verbundstoff-Strukturen verwendet werden, weisen mehrere Beschränkungen in Bezug auf den Lasttransfer zwischen den Materialien. Die vorliegende Doktorarbeit zielt auf die Einführung von Ultrasonic Joining (U-Joining) ab, einem neuen Fügeverfahren zur Herstellung von throught-the-thickness verstärkten Hybridverbindungen aus Metall und Faserverbundwerkstoff mit verbesserter out-of-plane Festigkeit. Um die Machbarkeit des Fügeprozesses zu demonstrieren und die Korrelation zwischen Prozess- und Fügeeigenschaften zu beschreiben, wurde ein Fallstudienansatz gewählt, der kommerziell erhältliches glasfaserverstärktes Polyetherimid und MIM-Structured Ti-6Al-4V verwendet.
description: Joining concepts that are traditionally used to join hybrid metal-composite structures present several limitations with regard to load transfer between the materials. The present doctoral thesis aims at introducing the Ultrasonic Joining (U-Joining), a new joining approach to produce through-the-thickness reinforced metal-composite hybrid joints that have improved out-of-plane strength. In order to demonstrate the process feasibility and describe the correlation between process and joint properties, a case study approach was chosen, using commercially available glass-fiber reinforced polyetherimide and MIM-Structured Ti-6Al-4V.

description: A series of reasons to take quantum unitary evolution seriously and explain the projection of the state vector as unitary and not discontinuous are presented, including some from General Relativity. This leads to an interpretation of Quantum Mechanics which is unitary at the level of a single world. I argue that unitary evolution is consistent with both quantum measurements and the apparent classicality at the macroscopic level. This allows us to take the wavefunction as ontic (but holistic), but a global consistency condition has to be introduced to ensure this compatibility. I justify this by appealing to sheaf cohomology on the block universe. As a consequence, Quantum Theory turns out to be consistent with a definite four-dimensional spacetime, even if this may consist of superpositions of different geometries. But the block universe subject to global consistency gains a new flavor, which for an observer experiencing the flow of time appears as "superdeterministic" or "retrocausal", although this does not manifest itself in observations in a way which would allow the violation of causality. However, the block universe view offers another interpretation of this behavior, which makes more sense, and removes the tension with causality. Such a block universe subject to global consistency appears thus as being post-determined. Here "post-determined" means that for an observer the block universe appears as not being completely determined from the beginning, but each new quantum observation eliminates some of the possible block universe solutions consistent with the previous observations. I compare the post-determined block universe with other proposals: the presentist view, the block universe, the splitting block universe, and the growing block universe, and explain how it combines their major advantages in a qualitatively different picture.

description: In this paper we prove that solutions of the f-plane approximation for equatorial geophysical deep water waves, which have the property that the pressure is constant along the streamlines and do not possess stagnation points,are Gerstner-type waves. Furthermore, for waves traveling over a flat bed, we prove that there are only laminar flow solutions with these properties.

description: We propose a mechanism that the soft supersymmetry breaking masses can be induced from the dynamical rearrangement of local U(1) symmetry in a five-dimensional model. The U(1) symmetry possesses several extraordinary features. The eigenstates of U(1) do not equal to those of boundary conditions. The U(1) charge of standard model particles does not equal to that of superpartners. A large U(1) charge hierarchy among superpartners and a standard model gauge singlet is necessary in order to obtain the masses of O(1)TeV.

description: The term “frugal innovation” has established itself in scholarly discourse as well as in actual business practice in a short time. Nevertheless, its theoretical antecedents and underpinnings remain unclear. In this study we present results of a bibliometric analysis, which indicate that the present-day understanding of frugal innovation is shaped primarily by discourses on “bottom of the pyramid”, “reverse innovation” and “disruptive innovation” and it has been targeted at “emerging economies”. Even though rediscovery of frugality’s virtue began in the developing world, it is spreading steadily to the economically developed world due to growing (global) demand for sustainable and affordable excellence. Frugal innovations are often associated with sustainability and development. Today, research on frugal innovations represents a very young and dynamic field: most scholarly publications and many of the references cited therein have been published in the past 5-6 years. Researchers would be, however, well-advised to incorporate insights on frugality and simplicity generated in other disciplines and other times, for example in the 1970s. Our study shows that the research on frugal innovations needs to take a calibrated, multidisciplinary approach.

description: Functional impairment is increasingly prevalent among middle-aged and older adults, with 2 in 5 adults over the age of 65 having some form of disability, the majority being limitations on mobility. Many older adults are able to maintain functional capacity well into later life, but the factors that contribute to high levels of function and the mechanisms by which they operate are unclear, although prior work has demonstrated the importance of social relationships for health. Guided by principles from the life course perspective and perspectives on social connectedness, this dissertation examined the role of social connectedness across the life course as a predictor of functional capacity in adulthood. I used existing longitudinal data from the national Midlife in the United States (MIDUS) study to pursue three central aims.
 First, Paper 1 compared theoretical and data-driven approaches to classifying life course relationships, including multiple dimensions of social connectedness at different time points across the life course. Results showed that the data-driven approach (i.e., latent profile analysis) was a stronger predictor of functional limitations than the theoretical approach and revealed relationship trajectories consistent with life course cumulative processes. Second, using the profiles obtained from Paper 1, Paper 2 probed the association between life-course social connectedness and functional limitations by examining the potential mediating role of candidate biological and behavioral mechanisms, and moderation by socioeconomic status (SES). Paper 2 findings suggested that observed differences in later-life functional limitations based on life-course social connectedness can be at least partially explained by physical activity, but do not vary by SES. Contrary to hypotheses, inflammation was not a significant mediator. Third, Paper 3 used monozygotic twin data and within-family analyses to sharpen the focus on potential causal associations between life-course social connectedness and adult functional status. Results suggested that the association is likely driven by genetic and/or shared environmental influences.
 Taken together, these results add to our understanding of social connectedness and health and address important gaps in the literature. These findings are used to generate theory- and intervention-relevant insights into the successful maintenance of health, independence, and function across the lifespan.
