description: In the first part of this thesis, the mechanistic insights behind the key step of this total synthesis, the diastereoselective Nazarov/ene tandem cyclization, are unravelled. First, the introduction of an additional methylene in the side chain served the purpose of understanding the connection between the flexibility of the side chain and the feasibility of the desired cyclization. Second, the cyclization in presence of a (Z)-substituent at the terminal olefin afforded only products whose double bond occupied the position of the former (E)-methyl group, suggesting selective migration of an hydrogen atom from the (E)-position. Third, the synthesis of a perdeuterated precursor, bearing a CD3-substituent in lieu of the (E)-methyl group, confirmed the aforementioned migration hypothesis. Finally, crossover experiments outruled the existence of an intermolecular proton/deuterium transfer, confirming a concerted, intramolecular ene-like mechanism. In the second part, the acquired chemical background for the stereoselective construction of spirocompounds via Nazarov/ene cyclizations was transferred to the total synthesis of (−)-illisimonin A, a caged sesquiterpenoid isolated by Ma et al. from the fruits of Illicium simonsii, commonly known as star anise. The construction of its unprecedented tricyclo[5.2.1.01,6]decane skeleton was attempted with an early-stage functionalization strategy and a late-stage parallel approach, in which C-11 functionalization followed one-carbon homologation. While the early-stage plan stranded at an advanced intermediate, the functionalization of the previously homologated spirocycle proved to be successful. A Ti(III)-mediated reductive cyclization of an epoxy-enone, a type III semipinacol rearrangement and a selective deprotection successfully led to a formal synthetic intermediate. In the third and final act, an enantioenriched cross-conjugated precursor for the key Nazarov/ene cyclization diastereoselectively built the desired stereotriad in the aforementioned spirocompound. In turn, this spiroketone followed the steps of its racemic congener, fruitfully reproducing the optimized synthesis until a second, more advanced, formal intermediate. A carboxylic acid-mediated White-Chen C−H activation gave access to (−)-illisimonin A and concluded this thesis.

title: Optimization Approaches and Information Systems for Integrated Humanitarian Logistics
Creators: name: Timperio, Giuseppe
Publisher: name: UNSPECIFIED
Year: 2024

description: Progressive urbanization of disaster-prone areas and the escalating impacts of climate change are contributing to a sharp increase in complex natural disasters. Amidst shrinking financial resources for disaster response, the need for improving decision-making in humanitarian logistics and supply chain management, the backbone of disaster relief absorbing between 60 and 80% of relief budgets, is imperative. Central to many challenges inhibiting effective and efficient provision of relief assistance is that most humanitarian organizations operate in silos. As a result, disaster response operations often experience suboptimal response times, over- or under-supply of necessary items, and higher-than-expected costs. In addressing these compelling challenges, the traditional organization- and execution-centric approach to humanitarian logistics is no longer sufficient. The increased complexity of humanitarian operations calls for a multidisciplinary research effort, with greater attention to ecosystem-aware, beneficiary-centric supply chain networks, with simultaneous attention to both planning and execution of humanitarian operations in consideration of the highly unpredictable and volatile environment relief assistance is delivered in. Despite the multifaceted nature of these challenges, rigorous, practice-focused research-based frameworks remain lacking in the existing body of knowledge. To fill this gap, this dissertation project presents a series of progressive multi-method decision support frameworks that integrate analytical and dynamic simulation approaches and rigorously validate them through realistic use cases, aspiring to address the multiple dimensions of the problem statement. By architecting modular frameworks that encompass models, data, knowledge, and technology, this dissertation goes beyond the use of standalone methods, striving to provide adaptable, practice-based approaches suitable for diverse disaster contexts and geographies.

description: Offene Spielsituationen und Mathematikförderung: Geht das zusammen? Auf den ersten Blick scheinen diese beiden Bereiche weit auseinanderzuliegen. Diese Masterthesis befasst sich mit der Frage, inwiefern sich eine individuell-adaptive mathematische Förderung auf die mathematischen Kompetenzen von Kindern mit heilpädagogischem Bedarf in einer Kindergartenregelklasse auswirkt. Dazu wird ein Förderprogramm entwickelt und durchgeführt, welches sich am individuellen Spielmaterial und den mathematischen Kompetenzen der Kinder orientiert. Das Auftreten von mathematischen Kompetenzen vor, während und nach der Projektphase wird bei zwei ausgewählten Kindern mittels Direct Behavior Rating beurteilt. Das Forschungstagebuch ermöglicht weitere Einblicke in das Verhalten der Kinder während der Projektphase. Die Resultate zeigen bei beiden Kindern einen Anstieg der mathematischen Kompetenzen im Rahmen des Projekts. Erkenntnisse aus dem Forschungstagebuch liefern Hinweise darauf, wie die Kinder mit unterschiedlichem Material an mathematische Fragestellungen herangegangen sind.

description: We experimentally investigate the dynamics of a persistent spin helix in etched GaAs wire structures of 2 to 80 um width. Using magneto-optical Kerr rotation with high spatial resolution, we determine the lifetime of the spin helix. A few nanoseconds after locally injecting spin polarization into the wire, the polarization is strongly enhanced as compared to the two-dimensional case. This is mostly attributed to a transition to one-dimensional diffusion, strongly suppressing diffusive dilution of spin polarization. The intrinsic lifetime of the helical mode is only weakly increased, which indicates that the channel confinement can only partially suppress the cubic Dresselhaus spin-orbit interaction.

description: We study the gradient flow for Yang-Mills theories with twisted boundary conditions. The perturbative behavior of the energy density $\langle E(t)\rangle$ is used to define a running coupling at a scale given by the linear size of the finite volume box. We compute the non-perturbative running of the pure gauge $SU(2)$ coupling constant and conclude that the technique is well suited for further applications due to the relatively mild cutoff effects of the step scaling function and the high numerical precision that can be achieved in lattice simulations. We also comment on the inclusion of matter fields.

description: Our knowledge of the diffuse emission that encompasses active regions is very limited. In the present paper we investigate two off-limb active regions, namely AR10939 and AR10961, to probe the underlying heating mechanisms. For this purpose we have used spectral observations from Hinode/EIS and employed the emission measure (EM) technique to obtain the thermal structure of these diffuse regions. Our results show that the characteristic EM distributions of the diffuse emission regions peak at log T = 6.25 and the cool-ward slopes are in the range 1.4 - 3.3. This suggests that both low as well as high frequency nanoflare heating events are at work. Our results provide additional constraints on the properties of these diffuse emission regions and their contribution to the background/foreground when active region cores are observed on-disk.

description: The electron propagator in a laser background has been shown to be made up of a series of sideband poles. In this paper we study this decomposition by analysing the impact of the residual gauge freedom in the Volkov solution on the sidebands. We show that the gauge transformations do not alter the location of the poles. The identification of the propagator from the two-point function is maintained but we show that the sideband structures mix under residual gauge transformations.

Wavelength-Tunable Infrared Metamaterial by Tailoring Magnetic Resonance Condition with VO2 Phase Transition

description: In this work, we report the design of a wavelength-tunable infrared metamaterial by exciting magnetic resonance with phase transition of vanadium dioxide (VO2). Numerical simulation shows a broad absorption peak at the wavelength of 10.9 um when VO2 is a metal, but it shifts to 15.1 um when VO2 changes to dielectric phase below its phase transition temperature of 68degC. The large tunability of 38.5% in the resonance wavelength stems from the different excitation conditions of magnetic resonance assisted by plasmon in metallic VO2 but optical phonons in dielectric VO2. The physical mechanism is elucidated with the aid of electromagnetic field distribution at the resonance wavelengths. A hybrid magnetic resonance mode due to plasmon-phonon coupling is also discussed. The results here would be beneficial for active control in novel electronic, optical and thermal devices.

description: Das kulturelle Erbe des Kosovo umfasst ein reiches Spektrum an archäologischem, architektonischem, spirituellem Erbe sowie Kulturlandschaften und ist ein edler Teil des Lebensumfelds und der Mentalität seiner Menschen. Obwohl unzureichend erforscht, gehören Mühlengebäude zu den wichtigsten Vermögenswerten des materiellen Kulturerbes im Kosovo. Man kann sagen, dass sie heute wohl einer vergangenen Zeit angehören, aber einst waren sie für die Menschen dieser Gegend von enormer Bedeutung – ein Synonym für Brot, Gastfreundschaft und Behausung. Alt und die meisten von ihnen fast vollständig verlassen, gibt es im Kosovo über 70 Mühlengebäude, denen es immer noch an angemessener Dokumentation, Analyse und Vergleich zwischen ihnen mangelt. Diese Forschungsarbeit soll zur Kulturerbe-Datenbank des Kosovo beitragen, um die Möglichkeit zu bieten, besser zu verstehen, was die Architektur dieser Gebäudetypologie zusätzlich zu ihrer wirtschaftlichen und sozialen Bedeutung beeinflusst hat, und schließlich den Weg für adaptive Wiederverwendungsdesigns zu ebnen.

Although insufficiently explored, mill-buildings constitute one of the most important assets of the material cultural heritage in Kosovo. One may say that they now probably belong to a bygone era, but once they were of enormous importance to the people of these areas – a synonym of bread, hospitality and housing. Old and most of them almost completely abandoned, there are over 70 mill-buildings in Kosovo that still lack proper documentation,analysis and comparison between them. This research work intends to contribute to Kosovo's cultural heritage database, to provide an opportunity to better understand what influenced the architecture of this building typology, in addition to their economic and social importance, as well as eventually to pave the way for adaptive re-use designs.

description: Die steigende Heterogenität der Schülerinnen und Schüler an den Regelschulen belastet die Lehrpersonen zunehmend. Das “Universal Design for Learning” (UDL) könnte hierfür eine Entlastung bieten, da seine Anwendung einen barrierefreien, nutzbaren und inklusiven Unterricht verspricht. Am Beispiel des Zürcher Mathematiklehrmittels “Mathematik Primarstufe 2” (ZML2) versucht die vorliegende Arbeit herauszufinden, wie stark das ZLM2 das Konzept des UDL berücksichtigt und ob eine Ergänzung diesbezüglich sinnhaft ist. Die im Verlauf der Arbeit erstellte Lehrmittelergänzung wurde mit zwei Schulklassen erprobt und anschliessend mittels Fragebogen ausgewertet. Die Resultate haben gezeigt, dass das ZML2 die Prinzipien des UDL nur teilweise berücksichtigt. Die Lehrmittelergänzung führte zwar zu einer signifikanten Verbesserung des Mathematikunterrichts bezüglich des UDL, jedoch wurden auch damit nicht alle UDLPrinzipien ausreichend erfüllt. Um dies zu erreichen, müssen weitere Forschungen und Testläufe durchgeführt werden.

description: The multiplexing capabilities of superconducting X-ray free-electron lasers (FELs) have gained much attention in recent years. The demanding requirements for photon properties from multiple undulator lines necessitate more flexible beam manipulation techniques to achieve the goal of "beam on demand". In this paper, we investigate a multiplexed configuration for the photoinjector of high-repetition-rate FELs that aims to simultaneously provide low-emittance electron beams of different charges. A parallel, multi-objective genetic algorithm is implemented for the photoinjector parameter optimization. The proposed configuration could drastically enhance the flexibility of beam manipulation to improve multiplexing capabilities and realize the full potential of the facility.

description: Packing frustration for confined fluids, i.e., the incompatibility between the preferred packing of the fluid particles and the packing constraints imposed by the confining surfaces, is studied for a dense hard-sphere fluid confined between planar hard surfaces at short separations. The detailed mechanism for the frustration is investigated via an analysis of the anisotropic pair distributions of the confined fluid, as obtained from integral equation theory for inhomogeneous fluids at pair correlation level within the anisotropic Percus-Yevick approximation. By examining the mean forces that arise from interparticle collisions around the periphery of each particle in the slit, we calculate the principal components of the mean force for the density profile - each component being the sum of collisional forces on a particle's hemisphere facing either surface. The variations of these components with the slit width give rise to rather intricate changes in the layer structure between the surfaces, but, as shown in this paper, the basis of these variations can be easily understood qualitatively and often also semi-quantitatively. It is found that the ordering of the fluid is in essence governed locally by the packing constraints at each single solid-fluid interface. A simple superposition of forces due to the presence of each surface gives surprisingly good estimates of the density profiles, but there remain nontrivial confinement effects that cannot be explained by superposition, most notably the magnitude of the excess adsorption of particles in the slit relative to bulk.

description: Graph Neural Networks (GNNs) are de facto solutions to structural data learning. However, it is susceptible to low-quality and unreliable structure, which has been a norm rather than an exception in real-world graphs. Existing graph structure learning (GSL) frameworks still lack robustness and interpretability. This paper proposes a general GSL framework, SE-GSL, through structural entropy and the graph hierarchy abstracted in the encoding tree. Particularly, we exploit the one-dimensional structural entropy to maximize embedded information content when auxiliary neighbourhood attributes are fused to enhance the original graph. A new scheme of constructing optimal encoding trees is proposed to minimize the uncertainty and noises in the graph whilst assuring proper community partition in hierarchical abstraction. We present a novel sample-based mechanism for restoring the graph structure via node structural entropy distribution. It increases the connectivity among nodes with larger uncertainty in lower-level communities. SE-GSL is compatible with various GNN models and enhances the robustness towards noisy and heterophily structures. Extensive experiments show significant improvements in the effectiveness and robustness of structure learning and node representation learning.

description: Recent measurements of the positron energy spectrum obtained from inverse beta decay interactions of reactor electron antineutrinos show an excess in the 4 to 6 MeV region relative to current predictions. First-principle calculations of fission and beta decay processes within a typical pressurized water reactor core identify prominent fission daughter isotopes as a possible origin for this excess. These calculations also predict percent-level substructure in the antineutrino spectrum due to Coulomb effects in beta decay. Precise measurement of this substructure can constrain nuclear reactor physics. The substructure can be a systematic uncertainty for measurements utilizing the detailed spectral shape.

description: Defects intentionally introduced into magnetic materials often have a profound effect on the physical properties. Specifically tailored neutron spectroscopic experiments can provide detailed information on both the local exchange interactions and the local distances between the magnetic atoms around the defects. This is demonstrated for manganese dimer excitations observed for the magnetically diluted three- and two-dimensional compounds KMn(x)Zn(1-x)F(3) and K(2)Mn(x)Zn(1-x)F(4), respectively. The resulting local exchange interactions deviate up to 10% from the average, and the local Mn-Mn distances are found to vary stepwise with increasing internal pressure due to the Mn/Zn substitution. Our analysis qualitatively supports the theoretically predicted decay of atomic displacements according to 1/r**2, 1/r, and constant (for three-, two-, and one-dimensional compounds, respectively) where r denotes the distance of the displaced atoms from the defect.

Chemical and temporal significance of intracontinental magmatism in the central Zambezi belt: implications on craton margin magmatic ore deposits
Creators: name: Ward, Laura A.
Publisher: name: University of Leicester

description: The evolution of craton margins creates the ideal conditions for Ni–Cu–(PGE) ore formation, though their tectonic setting and location along craton margins also make them important for studying the breakup of continents. The breakup of Rodinia resulted in the development of several long-lived intracontinental rift-basins across the African continent, including the Neoproterozoic Zambezi belt. The onset of extension in the Zambezi belt is constrained by the emplacement of the Kafue Rhyolite Formation at 875.31 ± 0.63 Ma. Age data from mafic–ultramafic intrusions indicate that Zambezi belt developed over a protracted 100 Ma period through several magmatic intervals, up until at least ca. 737 Ma. The chemistry and isotopic signatures of these intrusions depict a complex scenario of chemically and temporally different rocks that can broadly be grouped into: (1) variably-enriched tholeiitic N- to E-MORB compositions emplaced ca. 880–820 Ma; and (2) transitional to OIB-type compositions emplaced 795–737 Ma. The intrusions display a wide range of 143Nd/144Nd (ƐNd -1.8 to +9) and 176Hf/177Hf (ƐHf -15.7 to +19.3) compositions, which for several intrusions, plot above estimates for the depleted mantle for the time of formation. These values indicate a history of mantle depletion that pre-dates the formation of the Zambezi belt. Examples of decoupled Nd and Hf isotope compositions and increased 176Hf/177Hf indicate a complex history of mantle depletion, re-fertilisation, and mixing. These inferences have specific implications for targeting and evaluating Ni–Cu–(PGE) systems in the Zambezi belt. Intrusions containing appreciable sulphide are only recognised between 860–850 Ma. These results indicate that magmas emplaced during rift incipience were most fertile, formed during post-orogenic extensional magmatism after collisional convergence and arc tectonism associated with the Rodinia supercontinent cycle. One of the major challenges in the exploration of Ni–Cu–(PGE) deposits is the lack of a footprint beyond the host intrusions themselves. This new understanding may prove to be an important predictive tool in the Zambezi belt, and more broadly along the margin of the Congo craton, as it provides a way to prioritise segments with enhanced metal fertility. This study highlights that a multidisciplinary approach, combining independent geochronology with chemical and petrogenetic analyses can help to gain a more comprehensive understanding of ore deposit formation.

description: Particulate Organic Carbon (POC) plays a vital role in the ocean carbon cycle. Though relatively small compared with other carbon pools, the POC pool is responsible for large fluxes and is linked to many important ocean biogeochemical processes. The satellite ocean-color signal is influenced by particle composition, size, and concentration and provides a way to observe variability in the POC pool at a range of temporal and spatial scales. To provide accurate estimates of POC concentration from satellite ocean color data requires algorithms that are well validated, with uncertainties characterized. Here, a number of algorithms to derive POC using different optical variables are applied to merged satellite ocean color data provided by the Ocean Color Climate Change Initiative (OC-CCI) and validated against the largest database of in situ POC measurements currently available. The results of this validation exercise indicate satisfactory levels of performance from several algorithms (highest performance was observed from the algorithms of Loisel et al., 2002; Stramski et al., 2008) and uncertainties that are within the requirements of the user community. Estimates of the standing stock of the POC can be made by applying these algorithms, and yield an estimated mixed-layer integrated global stock of POC between 0.77 and 1.3 Pg C of carbon. Performance of the algorithms vary regionally, suggesting that blending of region-specific algorithms may provide the best way forward for generating global POC products.

description: The recognition of effective judicial protection under European Union law affects national regulations on the administration of justice. There is no doubt that the competence to regulate and act upon matters relating to the organisation and functioning of the national judiciary is an exclusive national competence, not conferred to the Union by the Member States. However, over the last couple of years, the Court of Justice has been implying that national measures concerning the national administration of justice cannot be contrary to the regulations on judicial protection as recognised by the Union. This European regulation works as a limit to those national measures related to the administration of justice, opening the door to a judicial review (or control) of these measures; a judicial control that uses European Union law (that relating to effective judicial protection) as a parameter or measure of judgment (review or control of “europeanness”). These pages discuss on which legal bases, in which cases and with which mechanisms this review is taking place.

description: Behavior and innervation suggest a high tactile sensitivity of elephant trunks. To clarify the tactile trunk periphery we studied whiskers with the following findings. Whisker density is high at the trunk tip and African savanna elephants have more trunk tip whiskers than Asian elephants. Adult elephants show striking lateralized whisker abrasion caused by lateralized trunk behavior. Elephant whiskers are thick and show little tapering. Whisker follicles are large, lack a ring sinus and their organization varies across the trunk. Follicles are innervated by ~90 axons from multiple nerves. Because elephants don’t whisk, trunk movements determine whisker contacts. Whisker-arrays on the ventral trunk-ridge contact objects balanced on the ventral trunk. Trunk whiskers differ from the mobile, thin and tapered facial whiskers that sample peri-rostrum space symmetrically in many mammals. We suggest their distinctive features—being thick, non-tapered, lateralized and arranged in specific high-density arrays—evolved along with the manipulative capacities of the trunk.

description: The aim of Harmonic Broadcasting protocol is to reduce the bandwidth usage in video-on-demand service where a video is divided into some equal sized segments and every segment is repeatedly transmitted over a number of channels that follows harmonic series for channel bandwidth assignment. As the bandwidth of channels differs from each other and users can join at any time to these multicast channels, they may experience a synchronization problem between download and playback. To deal with this issue, some schemes have been proposed, however, at the cost of additional or wastage of bandwidth or sudden extreme bandwidth requirement. In this paper we present an adaptive quasi harmonic broadcasting scheme (AQHB) which delivers all data segment on time that is the download and playback synchronization problem is eliminated while keeping the bandwidth consumption as same as traditional harmonic broadcasting scheme without cost of any additional or wastage of bandwidth. It also ensures the video server not to increase the channel bandwidth suddenly that is, also eliminates the sudden buffer requirement at the client side. We present several analytical results to exhibit the efficiency of our proposed broadcasting scheme over the existing ones.

description: In this article, we present Gammapy, an open-source Python package for the analysis of astronomical $\gamma$-ray data, and illustrate the functionalities of its first long-term-support release, version 1.0. Built on the modern Python scientific ecosystem, Gammapy provides a uniform platform for reducing and modeling data from different $\gamma$-ray instruments for many analysis scenarios. Gammapy complies with several well-established data conventions in high-energy astrophysics, providing serialized data products that are interoperable with other software packages. Starting from event lists and instrument response functions, Gammapy provides functionalities to reduce these data by binning them in energy and sky coordinates. Several techniques for background estimation are implemented in the package to handle the residual hadronic background affecting $\gamma$-ray instruments. After the data are binned, the flux and morphology of one or more $\gamma$-ray sources can be estimated using Poisson maximum likelihood fitting and assuming a variety of spectral, temporal, and spatial models. Estimation of flux points, likelihood profiles, and light curves is also supported. After describing the structure of the package, we show, using publicly available $\gamma$-ray data, the capabilities of Gammapy in multiple traditional and novel $\gamma$-ray analysis scenarios, such as spectral and spectro-morphological modeling and estimations of a spectral energy distribution and a light curve. Its flexibility and power are displayed in a final multi-instrument example, where datasets from different instruments, at different stages of data reduction, are simultaneously fitted with an astrophysical flux model.
