Publisher: name: International Journal on Magnetic Particle Imaging
Year: 2020

description: In magnetic particle imaging, the time consuming measurement of a system matrix is required before image reconstruction. Reduction of measurement time can be achieved with the help of compressed sensing, which is based on the sparsity of the system matrix in a suitable transform domain. In this work, we propose regularization functions to exploit the additional correlations in multi- patch system matrices. Experiments show that the resulting recovery method allows successful matrix recovery at higher undersampling factors than a standard compressed sensing recovery. Int. J. Mag. Part.

description: A characteristic feature of most Magnetic Particle Imaging and Spectrometry systems is the field generator, an electromagnetic coil that produces the excitation field, which in turn forces the magnetic nanoparticles to produce their unique fingerprint used in imaging and spectrometry. Effective power transfer from the power source to the field generator usually demands for an impedance matching network. Due to component tolerances or environmental conditions, implementation of such an impedance matching can be tedious. Additionally, the impedance matching might change under working conditions caused by e.g. heating of the components and the resulting change in their electrical properties. This contribution aims to firstly present a standard procedure for implementation of an impedance matching network, addressing the difficulties arising from unprecise component values, and secondly a concept for automatic impedance correction if the electrical properties of system components change. To achieve those objectives, it is exploited that the conductance of the matching network is invariant under a change of the parallel capacitance. Int. J. Mag. Part.

title: A comparative analysis of Barbados and Guyana with respect to colonial legacies, transnational processes and decolonizing activities involved in queer activism
Creators: name: Rambarran-Gill, Nastassia Sharana
Publisher: name: University of Glasgow
Year: 2024

description: This study offers an examination of queer social movements through an analysis of both transnational and decolonizing relations. It does this through a systematic comparative analysis of queer (or lesbian, gay, bisexual, transgender, queer plus (LGBTQ+)) activism in the two Caribbean countries of Barbados and Guyana. These sites share historical and cultural similarities, but differ geopolitically and demographically, with one important demographic difference being the presence of Indigenous peoples in Guyana. This context lent to a distinctive decolonizing methodology and the engagement of varying strands of social movement theory to examine how the trajectories of queer activism have been influenced by the overlapping forces of British colonialism and transnationalism, as well as other internal factors. The thesis advances the central argument that while the general queer activism arcs, movement dynamics and transnational relations in the two countries bear many commonalities, early key differences in the colonial milieu have resulted in moderate but significant and demonstrable divergences in particularities like strategies, political opportunities, funding landscapes, collective identity, movement cohesion, transnational engagements and interactions with Indigeneity. Queer activists’ transnational engagements with Global North actors occurred on a spectrum of power hierarchies and decolonizing considerations. Activists also utilized more implicit decolonizing praxes while proffering other paths of resistance to coloniality’s multi-pronged presence. Within these navigations, it is argued that deeper attention can be paid to decolonizing, and enhancing relational interactions, at both the transnational and local levels. These arguments emerged from online and archival research, participant observation and qualitative semi-structured qualitative interviews with forty-two activists in Barbados, Guyana and representatives from collaborating organizations in the Global North. Overall, this research makes a notable contribution to queer sociological analysis in the Global South by addressing both transnational and decolonizing elements of queer activism simultaneously. Grounded in activist realties, it also illustrates the critical necessity of contextual decolonial considerations around Indigeneity and the continuing effects of coloniality in queer activism, while offering possibilities for reorientations.

Manipulation of Paratexts & Exploitation of Subtitling Guidelines for Advocacy Purposes
Creators: name: Samir Ghanem, Abrar
Publisher: name: Humanities Commons
Year: 2023

description: This article studies some of the articles published by PMW (Palestinian Media Watch), which is a research institute that studies the Israeli-Palestinian conflict. The articles report events that took place between 2014 and 2015. The focus of these events is on two main incidents that were the cause of other related struggling incidents; the kidnapping of Muhammad Abu Khdeir and the Duma arson attack. The two events were the cause of other known incidents that took place during that time but were reported independently and out of the context of the two mentioned events, like Gaza 2014 war. Articles are translated from Arabic into English, and combine different paratextual elements in each. The articles aim at situating these events in a new frame by manipulating either the texts, or the paratexts they contain. The frame is the same in all PMW’s content. The frame, as this study suggests, depicts Palestinian people as ‘terrorists’ and Israel as a ‘state fighting terrorism.’ The content is ideologically motivated and framed; it follows in the footsteps of certain agenda.

title: Ethical decision-making in everyday business decisions
Creators: name: Fenech, Corinne
Publisher: name: University of Glasgow
Year: 2024

description: This thesis draws on and contributes to the literature on ethical decision-making and to the discussion of agency versus structure in institutional theory. It investigates ethical decision-making in ordinary business decisions through the lens of structuration theory. The overarching research aims are to investigate the manifestations of ethical decision-making in organisations, how such decision-making is influenced by agency and structure, and how unethical decision-making can be mitigated in organisations. This qualitative research comprised 24 semi-structured interviews with organisational decision-makers in Malta, selected through heterogeneous purposive sampling. Participants from diverse industries, professions and hierarchy levels were asked about their experiences of ethical decision-making. Data captured through these interviews was analysed and interpreted using open coding. The findings indicate that the micro, meso and macro environment impact decision-making to differing degrees. At a micro level, decisions may be influenced by the individual’s traits, interpersonal relationships and their organisational roles. At the meso level, organisations exert influence, ranging from explicit regulations to implied norms and culture. Although micro-decisions may appear detached from the macroenvironment, they are significantly influenced by societal norms, cultures, and industry practices. The findings also indicate that ethical decisions can be described as varying in terms of awareness of morality and agency. The level of awareness of morality indicates how aware decision-makers are of the ethical dilemma. The level of agency indicates the degree to which decision-makers perceive themselves to be in control of their own decisions. This research makes a theoretical contribution through a framework which describes a dual relationship between structure, modalities, material constraints and decision-makers, as well as the varying degrees of awareness in ethical decision-making. It provides an empirical contribution to descriptive ethics through the lived experiences of ethical decision-making and a practical contribution through recommendations for actions by individuals, organisations, educators, and society.
title: Extending polyoxometalates to palladium
Creators: name: Xu, Feng
Publisher: name: University of Glasgow
Year: 2012

description: This thesis focuses on inorganic polyoxopalladate cluster chemistry, which results from the reactive hydrolysis product of Pd(II). A series of new polyoxopalladates clusters, designated by {Pdn} (n = 4-84, where n is the number of Pd(II) in the cluster), was found in this study.

A supramolecular {Pd17} was first investigated. It was shown that the {Pd17} compound displays a structural variety compared to the parent. Also, a unique interactive
{Pd2} core was found in the centre of the cluster, indicated by an intriguing Pd-Pd short distance of 2.76 A. Furthermore, the host compound with a pristine {Pd15} cage structure was isolated later. Both of the novel structures are well characterized. A possible new type of host-guest chemistry between {Pd15} and {Pd17}, was studied by preliminary P-NMR and UV-Vis measurements.

The facile synthesis of a giant {Pd84} oxo-cluster wheel was revealed. The molecular wheel {Pd84} has an 7-fold symmetry, which is a rare large prime number. Based on the
successfully obtaining another polyoxopalladate cluster, {Pd10}, from a similar synthesis and MS data analysis, a formation mechanism of orderly {Pd84} was proposed. Furthermore, the production organisation of its building block, and driving force to the cyclic shape.

Further investigations focused on synthetic strategies in polyoxopalladates were carried out. A new cage structure of {Pd12} was isolated. The prototype of {Pd12X}, with one
encapsulated transition metal (X = Mn/Co/Ni), has been discussed. In addition, two hybrid polyoxopalladate clusters, {Pd7} and {Pd11}, and two novel Pd-containing sandwich-type polyoxometalates with tetrametallic-cores were revealed.
Co-optimisation of send and receive coils

description: Magnetic particle imaging exploits the nonlinear magnetization behaviour of iron oxide nanoparticles, by modulating the magnetic flux density of those particles. This modulation is achieved by creating time-varying magnetic fields using a drive coil. The generated signal is picked up with a receive coil. In order to minimize mutual influence, those coils need to be optimized. The decision process for an optimal combination of drive and focus field coil and the receive coil is described with respect to the signal chain and power consumption of the scanner. It is shown that the advantages of longer coils result in a linear increase of the power loss in the scanner, while the obtained sensitivity no longer increases relevantly. Based on this analysis a coil with favourable cost-benefit ratio can be chosen. Int. J. Mag. Part. Imag. 6(2), Suppl. 1, 2020, Article ID: 2009037, DOI: 10.18416/IJMPI.2020.2009037

description: A single-sided MPI scanner holds a great promise for a variety of clinical applications. In such a scanner the SPIOs response to the excitation is detected by a planar receive coil on the surface of the device. Due to a single-sided geometry, differentiating a small signal on a strong excitation background becomes a challenging task and further impinges the potential sensitivity gain, thus we implemented a new planar gradiometer receive coil configuration for our MPI scanner. The preliminary results imply the improved sensitivity of the device over the traditional single coil design. Int. J. Mag. Part.

description: In magnetic particle imaging (MPI), the information about the local environment, such as its viscosity and temperature, can be inferred via the relaxation behavior of the nanoparticles. As the nanoparticle signal also changes with drive field (DF) parameters, one potential problem for quantitative mapping applications is the optimization of these parameters. In this work, an accelerated framework is proposed for characterizing the unique response of a nanoparticle under different environmental settings. The proposed technique, called magnetic particle fingerprinting (MPF), rapidly sweeps a wide range of DF parameters, mapping the unique tau-fingerprint of a sample. This technique can enable simultaneous mapping of several parameters (e.g., viscosity, temperature, nanoparticle type, etc.) with reduced scan time. Int. J. Mag. Part.

description: Color magnetic particle imaging (MPI) techniques have recently gained popularity, with the purposes of distinguishing different nanoparticle types or nanoparticles in different environments. In this work, we extend a relaxation-based color MPI technique that we recently proposed, and make it applicable to rapid trajectories that distort the underlying mirror symmetry of the adiabatic MPI signal. We propose a method to recover the mirror symmetry, with delay and signal amplitude compensations. The proposed technique rapidly produces a relaxation map of the scanned region, without any prior information about the nanoparticles. Int. J. Mag. Part.

description: Magnetic Particle Imaging (MPI) is a tracer based medical imaging modality with great potential due to its high sensitivity, high spatial and temporal resolution, and ability to quantify the tracer concentration. Image reconstruction in MPI is an ill-posed problem that can be addressed by regularization methods that each lead to a bias. Reconstruction bias in MPI is most apparent in a mismatch between true and reconstructed tracer distribution. This is expressed globally in the spatial support of the distribution and locally in its intensity values. In this work, MPI reconstruction bias and its impact are investigated and a two-step debiasing method with significant bias reduction capabilities is introduced. Int. J. Mag. Part.

description: Optically active small-molecular trisazobenzene derivatives are explored that allow facile photo-induced fabrication of holographic volume gratings which are unusually stable over time compared to structures based on other small-molecular organic compounds. The origin of this favorable characteristic of such architectures is investigated with three compounds that structurally differ only in the length of an alkyl spacer positioned between the molecular core and the active azobenzene chromophores. Species comprising spacers of sufficient length, and that exhibit a latent liquid-crystalline phase, feature efficient formation of stable, ordered domains in which the three side groups orient perpendicular to the polarization of the inscribing light beam. It is demonstrated that molecular order in these domains can be significantly improved by annealing at temperatures between the glass transition temperature and the clearing point of the specific compounds. This phenomenon allows combining the highly desirable processing characteristic of relatively short holographic writing times with small molecules in the fabrication of stable volume gratings, the latter feature so far having been reserved predominantly for polymeric species.
Iron core coil designs for MPI

description: In Magnetic Particle Imaging, much of the power consumed during an imaging sequence is used for the generation of the selection and focus fields. In today’s MPI scanners three different concepts are applied to generate the gradient fields: Air coils, permanent magnets and coils with soft iron. Air coils and permanent magnets have the great advantage of good calculability by the Biot-Savart Law. On the way to a clinical imaging modality, the needed power for sufficient gradient strength demand the use of soft iron. In order to make good use of the ferromagnetic amplification properties, much more complex simulations have to be done. A recently published head scanner uses a soft iron yoke for field generation. In this study, we investigated different coil geometries with soft iron with respect to this head scanner. Int. J. Mag. Part.

description: In general, a third harmonic component of a magnetic response is used for magnetic nanoparticle imaging (MPI). However, when applying a high AC modulated magnetic field to magnetic nano-particles (MNPs), the size of the apparatus become large, and a high power source is required. Thus, we have been investigating an imaging method using a second harmonic with a signal intensity higher than that of the third harmonic. Since the signal of the second harmonic component has positive and negative peaks, signal processing is necessary to represent the position of the MNPs. Therefore, we investigated a method to quantitatively represent the position and the content of magnetic nanoparticles not using differentiation but applying a system function. Results showed that the identification of the amount and the position of MNPs was possible. Int. J. Mag. Part. Imag. 6(2), Suppl. 1, 2020, Article ID: 2009043, DOI: 10.18416/IJMPI.2020.2009043

description: In Magnetic Particle Imaging the determination of the system matrix is a time-consuming process. As the transfer function differs depending on the electronics of the receive chain, a system matrix recorded with one chain cannot be used for reconstruction of measurement data using a different receive chain. This leads to huge amounts of data as system matrices have to be recorded for every set of drive field strength, particle system and receiver chain setting. In this paper the complexity of this is reduced by the factor of the receiver electronics. For each receive path of our MPI system the transfer function is recorded and stored on the measurement device. When loading the data, the transfer-function is corrected which allows the exchange of the system matrices data between receiver chains. To demonstrate this system matrix data is compared and a successful reconstruction of an in vivo dataset is shown. Int. J. Mag. Part.

description: The quality of images in system function reconstruction (SFR) depends on an extensive calibration scan that acquires the system matrix (SM). A change in parameters of the scanner, trajectory, or magnetic nanoparticle requires the acquisition of a new SM. In this work, we analyze the parameter robustness of SFR with simulations. We investigate the effect of utilizing an existing SM in the case of a change in the aforementioned parameters. The results show that a new calibration scan is not needed, as long as the change is sufficiently small. Int. J. Mag. Part.

description: Magnetic particle imaging is a very useful tool in the detection of stroke. To study the ability of stroke in a mouse model the data acquisition is challenging as a mouse brain contains only a very small ratio of blood compared to large animals or humans. The effective concentration within the whole organ is therefore very small, especially compared to the heart or the liver. Typical MPI receiver coils however cover a sensitive region of around 30 mm to 50 mm and have a bore size of above 40 mm. This leads on the one hand to non-optimal signal coupling due to the distance to the particles and on the other hand strong signals from the heart can cause artifacts in the low signal regions. In this work we present a coil optimized for mouse brain imaging, which due to its small size, also dampens signal from regions outside of the coil. Int. J. Mag. Part.

description: Magnetic particle imaging has undergone rapid development, and its capabilities have been demonstrated in a wide variety of preclinical trials. Despite this growing body of in-vivo work, little attention has so far been paid to the impact of MPI imaging sequences on tissue, and the potential short- and long-term health implications. It is common within the MPI community to refer to the technique as being neither invasive, toxic, ionizing, nor damaging. However, little (if any) experimental work has been undertaken to verify these claims. Here, we present an experimental and theoretical study of the heat dissipation occurring during 3D imaging within a Lissajous scanning MPI device. Int. J. Mag. Part.

description: The PhD dissertation diagnoses the dominant epistemological debates in architecture and urbanism during the 20th and 21st centuries. It traces their transformations, paying special attention to Le Corbusier and Ludwig Mies van der Rohe's preference for perspective representation, to the diagrams of Team 10 architects, to the critiques of functionalism, and the upgrade of the artefactual value of architectural drawings in Aldo Rossi, John Hejduk, Peter Eisenman, and Oswald Mathias Ungers, and, finally, to the reinvention of architectural programme through the event in Bernard Tschumi and the Office for Metropolitan Architecture (OMA). Particular emphasis is placed on the spirit of truth and clarity in modernist architecture, the relationship between the individual and the community in post-war era architecture, the decodification of design process as syntactic analogy and the paradigm of autonomy in the 1970s and 1980s architecture, the concern about the dynamic character of urban conditions and the potentialities hidden in architectural programme in the post-autonomy era.
The PhD dissertation is structured into four parts corresponding to four generations of architects, highlighting the conceptual tools and the epistemological concerns at the centre of the architectural discourse and the design strategies at each historical moment. It investigates the transformation of the epistemological object of architecture by analyzing the mutations of the modes of representation that are at the centre of interest in each generation being considered and their addressee. In the first part of the dissertation, it is demonstrated that what was at the centre of interest was the individual and the bourgeois character of the addressee of architecture, and architecture symbolizes the value of its property by the addressee.
Dynamic concentration reconstruction for magnetic particle imaging using splines
Creators: name: Schmidt, Christiane

description: 4D Magnetic Particle Imaging (MPI) reconstructions with high temporal resolution are of high relevance for diagnostic purposes. In multi-patch measurements the data for single patches is not continuous. During the scan of one patch no data is acquired for the remaining patches. This impedes regularization by similarity of subsequent frames. We propose a method that models the dynamic tracer concentration with cubic B-splines which allows for reconstructions with high temporal resolution from only few frames. Int. J. Mag. Part.

description: Conversational search (CS) presents unique challenges, particularly context-awareness and data limitation. This dissertation investigates these challenges and proposes novel solutions to address them. We explore conversational query reformulation using a text-to-text model and a binary-term classifier, highlighting their advantages and applying techniques to improve performance, such as query clarity score and multi-model fusion. By combining both reformulation models, we achieved state-of-the-art results. Additionally, we developed a system that selectively incorporates responses into conversation history, improving the CS system’s ability to retrieve passages for ambiguous queries. To tackle the issue of limited training data, we introduced paraphrasing as a data augmentation method, increasing the size of our CS dataset by over 665% and enhancing language diversity. We used automatic paraphrase generation combined with human-in-the-loop techniques to produce a high-quality dataset, the Expanded-CAsT (ECAsT). The ECAsT dataset serves as a valuable resource for the CS research community, offering numerous applications. We utilized ECAsT to assess the robustness of CS evaluation concerning language diversity and to train two novel multi-turn paraphrasing models with potential applications in query expansion, data augmentation, and passage retrieval. This dissertation contributes to the advancement of conversational search by addressing its main challenges and providing innovative techniques and resources for the research community.
Creating and understanding musical fragments

Subjects: W300 - Music

description: This body of research critically engages with the notion of fragmentation in contemporary classical music through a set of interlinked compositions, accompanying recordings and scores, conference presentations and other publications. The overriding research question asks how fragmentation can be used and understood in a contemporary compositional paradigm. Each part articulates a response to the challenge posed by adopting fragmentation, with the aim not to give a blueprint for musical fragmentation, but to offer multiple perspectives â€“ each grounded in a theoretical and practical awareness of the topic â€“ that inform each other to create a deeper response to the research question.In the three compositions the question is explored through formal and structural means, the compositional methods employed, the use of musical material, and the musical sonorities and textures. These features can be observed in the scores through a variety of common features. Formal issues present the most literal interpretation, with each work presented as a series of short movements; within these, sonorities evoke ideas of fragility, delicacy, dislocation and fracturedness, all associated with the fragment. A variety of composition approaches are used in creating these works that engage with the idea that a fragment must belong to a larger unseen whole. These approaches reveal themselves through the use of musical material in the scores, and are explored further in the associated conference presentations and publication.The practical engagement with these works â€“ both from performers and audiences â€“ creates its own knowledge about the fragment. Whether actively or passively, each participant will make their own links between what is heard and played, and what a fragment represents. Creating this plural understanding of the subject is essential, and achieved here thanks to the practice-led and practice-based nature of the research and its dissemination in recordings and performances.

A novel representation of the MPI system function

description: In a recent publication, based on the Langevin model, the exact mathematical relationship between the system function and tensor products of Chebyshev polynomials of second kind has been derived for the case in which multidimensional excitation is used for magnetic particle imaging. There, a new expression for the system function in magnetic particle imaging was derived. To make this representation easily accessible, the present paper focusses on the more practical aspects of the theory without going deep into the mathematical proofs. In particular, we examine the contribution of the mixing factors to the total energy of a system function component. Int. J. Mag. Part.

description: One approach of image reconstruction in MPI is the system matrix based reconstruction. With this approach, in addition to the particle behavior, the sequence and the scanner properties are also calibrated and stored in a system matrix, so that a linear system of equations for the image reconstruction must be solved. However, the measurement of the system matrix is very time-consuming, depending on the desired spatial resolution. Independently of this, there are some remarkable symmetries within the system matrix that could be exploited to significantly reduce the calibration time. In the context of this work the theoretical description of a system matrix about Chebyshev polynomials is used to completely build a 3D system matrix by mirroring an octant and to successfully reconstruct an image.
