Corporate legal aspects of impact investments in British Columbia
Creators: name: Mosimann, Michael Peter
Publisher: name: University of British Columbia
Year: 2014

description: The historically grown distinction between for-profit corporations and non-profit organizations has caused a demand for new hybrid corporate forms that allow for the combination of the pursuit of a social or ecological goal and the generation of profits at the same time. These hybrid corporate forms are intended, among others, to attract social responsible investments in general and particularly impact investments, with which an investor aims to solve a social or ecological problem while making a profit. British Columbia has led the path in Canada by implementing the community contribution company (or C3 or CCC). This thesis argues that from a pure corporate legal point of view, a CCC may provide the highest and most enduring social impact, but depending on the interests of the investor, another corporate form might be more suitable for impact investments in British Columbia. After some general remarks on impact investing and the consideration of stakeholders’ interests by directors, the thesis first will provide a detailed analysis of the corporate legal features of the CCC. The discussion will show that most provisions governing the CCC intend to achieve two things, i.e., first that the CCC is managed in accordance with its community purpose and second, in particular through restrictions on dividends and asset transfers (asset lock provisions), to protect it from being stripped of its assets. The comparison with other corporate forms following the outline of the CCC’s features intends to draw a conclusion with regard to the suitability for impact investments. While some of the restrictions applicable to a CCC as well as the requirement to produce a community contribution report could be desirable from an impact investor’s point of view, others might be less advantageous or even disadvantageous. Before concluding the thesis with a summary of the findings as well as some thoughts about further research in this area, potential amendments to the CCC framework in order to increase its suitability for impact investments will be discussed. In addition, some high level thoughts on further incentives for social financing will be provided.

description: The scale invariance of the quantum fluctuations in de Sitter space leads to the appearance of de Sitter symmetry breaking infra-red logarithms in the graviton propagator. We investigate physical effects of soft gravitons on the local dynamics of matter fields well inside the cosmological horizon. We show that the IR logarithms do not spoil Lorentz invariance in scalar and Dirac field theory. The leading IR logarithms can be absorbed by a time dependent wave function renormalization factor in the both cases. In the interacting field theory with $λϕ^4$ and Yukawa interaction, we find that the couplings become time dependent with definite scaling exponents. We argue that the relative scaling exponents of the couplings are gauge invariant and physical as we can use the evolution of a coupling as a physical time.

description: New approaches towards high reliable thermal stable ohmic and Schottky contacts for GaN/AlGaN-HFETs have been developed and implemented in device structures. The contact technology has been systematically optimized towards i) good electrical properties, ii) superior contact morphology and contour definition and Hi) high reliability and thermal stability. HFETs employing source/drain contacts based on WSiN diffusion barriers sandwiched between an Ti/Al/Ti/Au internal layer system and an overlayer metal as well as WSiN/Au and Ir/Au gate contacts have demonstrated long term stability at 400°C, Even after temperature storage tests at 500°C no significant device degradation could be detected. Ir/Au Schottky gates have found to be stable at the rather high level of Schottky barrier height of about 1.1 eV resulting in dramatically reduced leakage currents as compared to standard Pt/Ti/Au gate contacts to GaN-HFETs.

description: Urbane grüne Infrastruktur (UGI) ist von zentraler Bedeutung für resiliente Städte, da sie essentielle Ökosystemleistungen (ÖSL) bereitstellt. Neben ÖSL kann UGI auch negative Effekte (disservices) erzeugen. Die Nutzung von ÖSL und disservices hängt dabei von persönlichen Präferenzen der Nutzer*innen und dem UGI-Design ab. Diese Dissertation erfasst die tatsächliche Nutzung von ÖSL sowie die Wahrnehmung von disservices durch UGI-Nutzer*innen in Leipzig, Deutschland und wie diese durch spezifische UGI-Merkmale beeinflusst werden. Außerdem zeige ich Diskrepanzen zwischen den Vorstellungen der Bürger*innen bezüglich der zukünftigen UGI-Entwicklung und lokalen Planungsschwerpunkten. Basierend auf den zentralen Ergebnissen der Arbeit formuliere ich Gestaltungsprinzipien für die UGI-Planung: Mehr Vielfalt von UGI und Baumbestand, Integration von städtischer Wildnis, Verbesserung der grauen Infrastruktur und sozioökonomischer Aspekte und Beteiligung der Bürger*innen an Planung und Pflege.
description: With regard to increasing inhabitant numbers in cities, urban green infrastructure (UGI) providing essential ecosystem services (ES) becomes a key solution for designing resilient cities. Besides ES, UGI can co-create disservices/disturbances. The flow of ES and disservices depends on different personal preferences as well as the UGI design. This dissertation aims to highlight ES flow, benefit, and disservice perception of UGI visitors in Leipzig, Germany, and how this is influenced by specific UGI characteristics. Furthermore, I highlight mismatches between citizens’ ideas for future UGI development and local planning foci. Based on central findings from the assessment, I formulate implications for UGI planning: increasing the diversity of UGI and tree cover, integrating urban wilderness, enhancing grey infrastructure and socio-economic aspects, and facilitating citizens’ participation in management and maintenance of UGI.

description: Lung cancer (LC) is one of the major and risky health defects even the serious cause for death in concurrent era. But no potential drugs even chemotherapeutic agents have been discovered with approval of health safety although some non-toxic biological macromolecules, such as polysaccharides and polysaccharide–protein complexes, have obtained as anti-lung cancer properties. This study conveys the anti-lung cancer properties of 45 polysaccharide derivatives collected from PubChem database. Primarily, the PASS prediction was performed to depict their anti-cancer activity, and 37 compounds showed the desired results. Next, the chemical descriptors, such as HOMO, LUMO, softness, and hardness etc, were calculated through the density functional theory (DFT) for quantum properties. Secondly, the auto molecular docking was executed to delineate the protein-ligand interactions, binding ability and inhibition of active sites of proteins. Additionally, the compounds showed docking score more than −6.40 kcal/mol, and the highest binding affinity was at −10.00 kcal/mol even 15 compounds have higher binding score (-8.6 to −10.0) than approved drugs, Gemcitabine. Succeeding, the most common protein residue, VAL 647, was blocked by ligands for the main protein (1X2J). In addition, five protein’s active sites were determined to make the relative study of protein-ligand interactions. As a result, the target docking against five proteins was performed, and it was found that the targeted docking score as the binding affinity is lower than auto docking. Finally, a comparative study between auto docking and targeted docking was performed for the most common five lung cancer proteins founded in three organisms. Communicated by Ramaswamy H. Sarma

Sate-of-the-art results on the dc, microwave, power, and noise characteristics of these devices on sapphire and SiC substrates are discussed. It is evident that AlGaN/GaN HFETs will be used for high power applications at microwave frequencies in the future. It is also possible that these devices will find applications for low noise amplifiers.

description: A high efficiency 2.4-V operation dual delta doped AlGaAs/ InGaAs/GaAs pseudomorphic high electron mobility transistor (PHEMT) for personal communications has been developed. The 20.16mm gate width device operating at a drain bias of 2.4 V at 1.9 GHz gives an output power of 30.0 dBm and a power added efficiency over 60%. The high efficiency at 2.4 V bias is attributed to the dual delta doped PHEMT structure which has high drain current and high electron mobility and to the shrinkage of the device layout which results in the low knee voltage and low source resistance of the device.

description: Seit ihrer Entdeckung durch die ersten genomweiten Studien in den frühen 2000er Jahren wurde die funktionelle Bedeutung langer nicht-kodierender RNAs (lncRNAs) diskutiert. Ursprünglich erfolgte die Einstufung der lncRNAs als "Transkriptionsrauschen" ohne biologische Funktion, aber die Forschung des letzten Jahrzehnts hat gezeigt, dass sie wichtige Modulatoren der Genexpression in Eukaryoten sind. In Pflanzen sind lncRNAs an der Regulierung einer Vielzahl von biologischen Prozessen beteiligt, darunter Blütezeit, Wurzelentwicklung und Reaktion auf abiotischen und biotischen Stress. Eine bestimmte Klasse von lncRNAs sind natürliche Antisense-Transkripte (lncNATs), die vom komplementären DNA-Strang eines proteinkodierenden Gens transkribiert werden. Im Focus dieser Arbeit steht ein lncNAT, das vom Gen At4g14548 der Modellpflanze Arabidopsis thaliana kodiert wird, und dessen regulatorisches Potenzial auf die Expression des proteinkodierenden Gens INDOLE-3-ACETIC ACID INDUCIBLE 14 (IAA14).
description: Since their discovery by the first genome-wide studies in the early 2000s, the functional relevance of long non-coding RNAs (lncRNAs) has been debated. They were initially classified as 'transcriptional noise' without biological function, but research in the last decade has shown that they are important modulators of gene expression in eukaryotes. In plants, lncRNAs are involved in the regulation of a variety of biological processes, including flowering time, root development, and response to abiotic and biotic stress. A particular sub-class of lncRNAs are natural antisense transcripts (lncNATs) that are transcribed from the complementary DNA strand of a protein-coding gene. This thesis focuses on a lncNAT encoded by the At4g14548 gene of the model plant Arabidopsis thaliana and its regulatory potential on the expression of the protein-coding gene INDOLE-3-ACETIC ACID INDUCIBLE 14 (IAA14).

description: Novel materials based on sustainable materials with high absorption capacity are still rare for the separation of organic liquids or oil spills and water. In this report, ultra-light nanocomposite aerogels consisting of sustainable bacterial cellulose (BC) and graphene oxide (GO) were constructed after an eco-friendly freeze-drying process for the first time. Due to the hydrophilic properties of both materials and the highly porous structure, BC/GO aerogels could highly absorb not only organic liquids, such as cyclohexane and DMF, but also water. Specific absorption for organic liquids was achieved after the reduction of GO using H₂ gas, which led to nanocomposite aerogels of BC and reduced GO. They could specifically absorb 135–150 g organic liquids per g of their own weight, even with a high content of 80% BC in the nanocomposite aerogel.

description: In this paper we present a theoretical framework for determining dynamic ask and bid prices of derivatives using the theory of dynamic coherent acceptability indices in discrete time. We prove a version of the First Fundamental Theorem of Asset Pricing using the dynamic coherent risk measures. We introduce the dynamic ask and bid prices of a derivative contract in markets with transaction costs. Based on these results, we derive a representation theorem for the dynamic bid and ask prices in terms of dynamically consistent sequence of sets of probability measures and risk-neutral measures. To illustrate our results, we compute the ask and bid prices of some path-dependent options using the dynamic Gain-Loss Ratio.

description: In this paper, a balanced common gate mixer is presented. The common gate configuration al-lows 0.8 um MESFETs to be used at frequencies in ex-cess of their ft by eliminating the Miller effect. Mea-surements on the mixer indicate a conversion loss of 10.7 dB, with a third order intercept at 0 dBm output pow-er. This performance is in the range of reported mixers at this frequency, even though most mixers use higher-tolerance and more expensive processes.

description: We show how the known theory of noncommutative Orlicz spaces for semifinite von Neumann algebras equipped with an fns trace, may be recovered using crossed product techniques. Then using this as a template, we construct analogues of such spaces for type III algebras. The constructed spaces naturally dovetail with and closely mimic the behaviour of Haagerup $L^p$-spaces. We then define a modified $K$-method of interpolation which seems to better fit the present context, and give a formal prescription for using this method to define what may be regarded as type III Riesz-Fischer spaces.

description: Directed acyclic graphs are the basic representation of the structure underlying Bayesian networks, which represent multivariate probability distributions. In many practical applications, such as the reverse engineering of gene regulatory networks, not only the estimation of model parameters but the reconstruction of the structure itself is of great interest. As well as for the assessment of different structure learning algorithms in simulation studies, a uniform sample from the space of directed acyclic graphs is required to evaluate the prevalence of certain structural features. Here we analyse how to sample acyclic digraphs uniformly at random through recursive enumeration, an approach previously thought too computationally involved. Based on complexity considerations, we discuss in particular how the enumeration directly provides an exact method, which avoids the convergence issues of the alternative Markov chain methods and is actually computationally much faster. The limiting behaviour of the distribution of acyclic digraphs then allows us to sample arbitrarily large graphs. Building on the ideas of recursive enumeration based sampling we also introduce a novel hybrid Markov chain with much faster convergence than current alternatives while still being easy to adapt to various restrictions. Finally we discuss how to include such restrictions in the combinatorial enumeration and the new hybrid Markov chain method for efficient uniform sampling of the corresponding graphs.

Sie können während ihres Lebenszyklus auch in die Umwelt gelangen. In der vorliegenden Arbeit wurde die toxikologische Wirkung von BaSO4-NP auf verschiedene Zellkulturmodelle der humanen Lunge, wie die Zelllinie BEAS-2B, die primären Zellkulturen des Bronchus und der peripheren Lunge sowie Miniorgankulturen des Bronchus und der peripheren Lunge untersucht. Weiterhin wurde das in-vitro-Modell der Miniorgankulturen charakterisiert und auf seine Eignung als Langzeitkulturmodell geprüft. Insgesamt konnte gezeigt werden, dass BaSO4-NP moderate Auswirkungen auf die verschiedenen Zellkulturmodelle haben. Die Miniorgankulturen zeigten über einen Zeitraum von bis zu drei Monaten eine stabile metabolische Aktivität. Eine zelluläre Veränderung konnte jedoch bereits nach etwa vier Wochen beobachtet werden.
description: Engineered nanomaterials (NMs), such as barium sulfate nanoparticles (BaSO4-NP), are widely and increasingly used in various fields of industry, cosmetics and medicine. They can also enter the environment during their life cycle. In the present study, the toxicological effect of BaSO4-NP on different cell culture models of human lung, such as BEAS-2B cell line, primary cell cultures of bronchus and peripheral lung as well as miniorgan cultures of bronchus and peripheral lung, was investigated. Furthermore, the in vitro model of the miniorgan cultures was characterized and tested for its suitability as a long-term culture model. Overall, BaSO4-NP were shown to have moderate effects on the different cell culture models. The miniorgan cultures showed stable metabolic activity over a period of up to three months. A cellular change could already be observed after about four weeks.
Reciprocity in quantum, electromagnetic and other wave scattering

description: The reciprocity principle is that, when an emitted wave gets scattered on an object, the scattering transition amplitude does not change if we interchange the source and the detector - in other words, if incoming waves are interchanged with appropriate outgoing ones. Reciprocity is sometimes confused with time reversal invariance, or with invariance under the rotation that interchanges the location of the source and the location of the detector. Actually, reciprocity covers the former as a special case, and is fundamentally different from - but can be usefully combined with - the latter. Reciprocity can be proved as a theorem in many situations and is found violated in other cases. The paper presents a general treatment of reciprocity, discusses important examples, shows applications in the field of photon (Mössbauer) scattering, and establishes a fruitful connection with a recently developing area of mathematics.

Modified universalism for cross-border insolvencies : does it work in practice?
Creators: name: Ouatu, Marcela
Publisher: name: University of British Columbia
Year: 2014

description: This thesis is a study of the application by courts of Canadian and British versions of the UNCITRAL Model Law on Cross-Border Insolvency. The Model Law proposes a legal framework that has as its theoretical foundation the modified universalism theory. By trying to determine whether the application of the Model Law provisions on core concepts of this Law promotes such goals as efficiency, fairness, predictability and protection for local interests in cross-border insolvency cases, this study ultimately assesses whether modified universalism works in practice. Modified universalism is a relatively new theory for the resolution of cross-border insolvencies that gained international and national acceptance two decades ago. It recognizes that a cross-border case should be administered under a single controlling insolvency proceeding governed by the laws of the country commencing that proceeding. However, the theory allows countries other than the country where the insolvency proceeding was commenced, before giving deference to the controlling proceeding, to determine whether such an act of cooperation would infringe on local interests. On the one hand, the centralization of the administration of a cross-border insolvency case is thought to bring efficiency, fairness and predictability to this process. On the other hand, because of the diversity of national insolvency laws, a centralization of the administration of such cases may infringe on local interests, such as the interest to protect the legitimate expectations of creditors or to further fundamental local public policies. The success of the Model Law, and ultimately of the modified universalism theory, depends on how courts strike a balance between these goals when considering requests for recognition of foreign insolvency proceedings and for relief in favor of these proceedings. The study concludes that the Canadian and British courts’ decisions strengthen rather than weaken the claim that the Model Law works in practice. Such a conclusion in turn suggests that modified universalism can serve as the theoretical foundation of a workable legal framework for the resolution of cross-border insolvencies. This finding may be important for countries that consider revising their cross-border insolvency laws in an effort to facilitate the administration of cross-border insolvency cases.

description: Research provides discovery in the present, and a legacy for the future. The knowledge gained is in pursuit of a more complete understanding of the world, natural and social. However, research is not a static entity. Much can be learned by examining past outputs of researchers. Never a neutral activity, research is paradigmatically embedded, always with a purpose in mind. Formal research of one kind or another has long been conducted in the Solomon Islands archipelago; it has provided a rich example of Pacific research as unfinished work, waka hem no finis yet, which resonates with the bodies of research from other Pacific contexts. In this article, we mine the research past of Solomon Islands to examine the directions taken over time by researchers. We then then pay attention to recent research, honouring the work of emerging researchers and the Solomon Islandcentric steerage that some are currently offering. Finally, we speculate on future directions that have the potential to further contextualise research, supporting it to reflect local thinking and lifeways, and offering wisdom to the wider Pacific and beyond. We hope that this reflexive journey will encourage Pacific researchers, including those serving Solomon Islands, to fully be themselves in their own spaces. In doing so, may they bring honour to all those who contribute to Pacific research that seeks the common good and wisdom to those that seek it.

description: We study Fourier-Mukai equivalence of K3 surfaces in positive characteristic and show that the classical results over the complex numbers all generalize. The key result is a positive-characteristic version of the Torelli theorem that uses the derived category in place of the Hodge structure on singular cohomology; this is proven by algebraizing formal lifts of Fourier-Mukai kernels to characteristic zero. As a consequence, any Shioda-supersingular K3 surface is uniquely determined up to isomorphism by its derived category of coherent sheaves. We also study different realizations of Mukai's Hodge structure in algebraic cohomology theories (etale, crystalline, de Rham) and use these to prove: 1) the zeta function of a K3 surface is a derived invariant (discovered independently by Huybrechts); 2) the variational crystalline Hodge conjecture holds for correspondences arising from Fourier-Mukai kernels on products of two K3 surfaces.

Majority rule and minority protection in private corporations : a comparative appraisal of the problems and remedies under the Canadian and Nigerian jurisdictions
Creators: name: Eluromma, Charles Onyehinim
Publisher: name: University of British Columbia
Year: 2014

description: This thesis examines, in comparative terms, Canadian and Nigerian laws relating to the concept of corporate majority rule and minority protection from majority opportunism and oppression in private corporations. The key shareholder remedies of derivative actions and oppression are comparatively discussed, with highlights of the similarities and differences in both remedies under Canadian and Nigerian laws. From theoretical perspectives, this thesis examines the theory that considers the corporation a nexus for a set of contracting relationships among parties. It also considers the proprietary conceptualisation of the corporation. Another theory sees the corporation as an agency relationship between two individuals with differing goals and interests. Lastly, the legal personality theory of the corporation, which considers the corporation a legal person capable of acquiring rights and assuming obligations, is discussed. Understanding of these theories gives better insights into reasons why conflicts arise amongst corporate stakeholders. A comparative appraisal of the key minority shareholder remedies of oppression and derivative actions under Canadian and Nigerian corporate laws reveals certain areas of convergence and other areas of uniqueness. This work demonstrates that the shareholder remedies available in the two jurisdictions are very similar in nature and, in most cases, known by the same names. However, there are some differences bordering on, among others, proper parties to commence shareholder litigations, length of pre-action notice, and the codification of common law rules into the corporate statute. For instance, while Nigeria statutorily incorporates the common law rule in Foss v. Harbottle and its exceptions into its corporate law, Canada only utilises the rule for historical and analytical purposes. This thesis advocates a reconsideration of the minority shareholder remedy of derivative actions with regard to close corporations, and the absence of a principled test for determination of liability under the oppression remedy. The attitude of the courts has always been to treat each case according to its peculiar facts. It is further suggested that the courts could, in the exercise of their discretion, liberally interpret the provisions of current corporate statutes to include discretionary, non-traditional corporate stakeholders, such as the environment, as beneficiaries of the dynamic remedy of oppression.

description: Der Beitrag befasst sich mit der Navigation von autonomen mobilen Robotern anhand von Videodaten. Es wird ein Ansatz zur Verbesserung visueller Odometriealgorithmen vorgestellt, der die Idee der Einflussnahme auf die Bilddaten durch ein aktives Kamerasystem aufgreift, ohne tatsächlich eine Aktorik zu benutzen. Es wird gezeigt, dass durch virtuelle Fixationen das räumliche Muster des Bildflusses so verändert werden kann, dass die daraus berechneten Kamerabewegungen genauer werden. Zur Berechnung der Kamerabewegung wird der aktive 7-Punkt-Algorithmus eingeführt. Anhand von statistischen Auswertungen wird abgeleitet, welche Fixationspunkte dazu besonders geeignet sind und ein Verfahren beschrieben, wie geeignete Fixationspunkte ausgewählt werden können. Desweiteren wird ein Vergleich zwischen dem virtuell-aktiven Ansatz und einem genauen visuellen Odometrieverfahren auf aktuellem Stand der Technik gegeben.

description: T/R modules suitable for spaceborne SAR instruments have to fulfil very strong requirements given by the challenging environmental and electrical conditions in space. This paper shows that the HBT (Heterojunction-Bipolar-Transistor) technology is able to meet these requirements for future SAR systems. For this application a separate breadboard Tx-chain as well as a T/R module have been realised which operate in X-Band and use the HBT technology for the high power chain. For the breadboard Tx-chain with driver and HPA in balanced configuration an output power of 39.5 dBm with an efficiency of 32.5% at 10% duty cycle was achieved. For the medium power T/R module with HBT driver and HPA in single ended configuration the output power is stabilised by a power control loop to 35 dBm with an overall module efficiency of better than 11.5% at 10% duty cycle. Full amplitude and phase stability of the T/R module is realised by a phase stable variable gain amplifier (VGA) and a 7-bit phase shifter. An accuracy of ± 0.5 dB in Rx gain and ± 6° in Rx/Tx phase under all operating conditions has been achieved by a novel and highly flexible calibration method. The paper will discuss the T/R module architecure with emphasis on the Tx-chain with HBT-amplifiers (fabricated at UMS) and the realised concept for the power control loop. Furthermore the T/R module performance will be presented with respect to SAR system requirements.

description: Der Beitrag befasst sich mit vernetzten dynamischen Multi-Agenten-Systemen (MAS), die Konsens über ihre Zustände bei unsicherer Datenübertragung und Sensorrauschen erreichen sollen. Dazu wird eine Analogie zwischen dem klassischen Consensus-Protokoll und dem Gauß’schen Belief Propagation hergestellt. Das Consensus-Problem wird als stochastischer Prozess modelliert, wodurch Unsicherheiten über die Anfangszustände und Übertragungsunsicherheiten explizit bei der Modellierung berücksichtigt werden können. Es werden die Voraussetzungen für dezentrale Inferenz hergeleitet, zwei dezentrale approximative Inferenz-Protokolle entworfen und ein Gauß’sches Consensus-Protokoll realisiert. Weiterhin wird der Zusammenhang zwischen Kommunikationsdichte und Approximationsfehler dargelegt. Schließlich wird gezeigt, dass die Hinzunahme von Messunsicherheiten zu einem dezentralen Entwurf eines Kalman-Filters für Consensus-Systeme führt.
Computer-aided analysis of surface-state effects on kink phenomena in GaAs MESFETs

description: Effects of surface states on kink phenomena in GaAs MESFETs are studied by two-dimensional (2-D) DC and transient sim-ulation including impact ionization of carriers. The Spicer's unified defect model is adoped for a surface-state model. It is shown that a kink in the DC current-voltage characteristics could arise due to a space-charge effect originated from impact ionization of holes and the follow-ing hole capturing by the surface traps. Tran-sient or dynamic simulation indicates that the trap-related kink phenomenon is a rather slow process.

description: In dieser Arbeit wurden die Mutantenlinien Glucosinolate Content and Composition 7 (gcc7) und gcc8 funktionell analysiert. Die Mutation in gcc8 führt zum Funktionsverlust des Schwefeltransporters SULTR1;2 und zu verringertem Glukosinolat- (GSL-) gehalt. SULTR1;2 beeinflusst den primären und sekundären Schwefelhaushalt. Durch Einzelnukleotidaustausche wurden Varianten generiert, um Transport- und Signalfunktion von SULTR1;2 als potentiellen Transzeptors getrennt zu untersuchen. In gcc7 weist IQD1 eine erhöhte Expression auf. IQD-Proteine binden Calmodulin und spielen wahrscheinlich eine Rolle in der Ca2+ Signalkette. IQD1 ist an Mikrotubuli und im Zellkern lokalisiert. In dieser Arbeit wurde erstmals die Funktion von IQD1 im Zellkern und für die Genexpression untersucht. Die neu generierten IQD1-Missexpressionslinien wiesen keinen veränderten GSL- oder Phytohormongehalt auf. Eine mögliche Funktion in der Pflanzenabwehr und GSL-Biosynthese von IQD1 zusammen mit KLCR2, CAM2 und WRKY21 wurde in Transaktivierungsexperimenten untersucht.
description: In this study mutants Glucosinolate Content and Composition 7 (gcc7) and gcc8 are functionally characterized. The mutation in gcc8 leads to a loss of function of the major sulfate transporter SULTR1;2 and to lower glucosinolate (GSL) content. SULTR1;2 affects the primary and secondary sulfur metabolism. Variants were generated via single nucleotide exchanges to uncouple transport and signaling function of the potential Transceptor SULTR1;2. In gcc7 the gene locus of IQD1 shows elevated expression. IQDs are CaM binding plant proteins and might play a role in Ca2+ signaling cascades. IQD1 is associated with microtubules (MT) and localized to the nucleus. For the first time this work focuses on the nuclear IQD1 function in gene expression. Newly generated IQD1 missexpression lines showed no altered GSL or phytohormone content compared to the wild type. A function in plant defense and GSL biosynthesis of IQD1 in in a complex together with KLCR2, CAM2 and WRKY21 were analysed via a transactivation assay.

description: In the framework of time-dependent geometric scattering theory, we study the existence and completeness of the wave operators for perturbations of the Riemannian metric for the Laplacian on a complete manifold of dimension $n$. The smallness condition for the perturbation is expressed (intrinsically and coordinate free) in purely geometric terms using the harmonic radius; therefore, the size of the perturbation can be controlled in terms of local bounds on the injectivity radius and the Ricci-curvature. As an application of these ideas we obtain a stability result for the scattering matrix with respect to perturbations of the Riemannian metric. This stability result implies that a scattering channel which interacts with other channels preserves this property under small perturbations.

description: Let g be a simplicial Lie algebra with Moore complex Ng of length k. Let G be the simplicial Lie group integrating g, which is simply connected in each simplicial level. We use the 1-jet of the classifying space of G to construct, starting from g, a Lie k-algebra L. The so constructed Lie k-algebra L is actually a differential graded Lie algebra. The differential and the brackets are explicitly described in terms (of a part) of the corresponding k-hypercrossed complex structure of Ng. The result can be seen as a geometric interpretation of Quillen's (purely algebraic) construction of the adjunction between simplicial Lie algebras and dg-Lie algebras.

description: An undergraduate research project is outlined whose goal was to use the TCAD tools to simulate the performances of GaAs- and SOI-based devices and to compare them with the corresponding silicon-based devices. Students used the Silvaco Corporation's "Virtual Wafer Fab" (VWF) package consisting of process simulation software called ATHENA, device layout software called DevEdit and device simulation software called ATLAS to simulate GaAs, SOI as well as conventional silicon devices. They explored the capabilities of these TCAD programs for five different GaAs and SOI devices including short-and long-channel JFETs, digital GaAs E-MESFETs, HEMTs and SOI BJTs.
