A platform to restore intra-tissue flow in live explant assays
Creators: name: Chatzidimitriou, Foivos
Publisher: name: Imperial College London
Year: 2021

description: Tissue resection during first-line surgery is a standard strategy in the clinic for several life-threatening diseases, such as cancer. In case of malignancy, despite the benefits from surgery, cancer often becomes treatment-resistant and metastasises, limiting therapeutic options and patient survival. Due to tumour heterogeneity, treatment personalisation can improve patient outcomes, however tools based on native tissue samples, used for patient-specific drug screening remain very limited. This is primarily due to the diffusion-limited mass transport in static culture conditions, where tissue viability is rapidly reduced due to ischemia. Our aim is to develop a platform that restores intra-tissue flow through native tissue specimens to prolong their preservation ex vivo. Flow of culture media around tissue specimens has been commonly used for sample preservation. However, the efficacy of most currently available platforms has been limited, as ex vivo specimen perfusion is not facilitated in these technologies. As fluid is allowed to travel around specimen periphery, intra-tissue flow is hydraulically disadvantaged and benefits from culture media renewal only affect cells within 200 μm from explant surface. In this thesis, a novel system is presented that comprises a channel-based device with a suitably-designed constriction to block peri-fusion (i.e. flow around the tissue) and facilitate specimen entrapment and perfusion. Using a syringe pump, device efficacy to facilitate intra-tissue flow was investigated, showing that the induced perfusion occurred through both the vasculature and the interstitium. The effects of perfusion on specimen maintenance and function were also investigated. It was showed that healthy mouse liver and cancerous mouse and human omental specimens were better preserved under perfused conditions in the developed apparatus for 48h. Intra-tissue flow was also effective to inhibit cell metabolism after a 2h-specimen perfusion with a metabolic poison, suggesting this system may have great potential for predictive, live explant assays.

Experimental and computational study of self-heating ignition and calorimetry of Lithium-ion batteries during storage
Creators: name: He, Xuanze
Publisher: name: Imperial College London
Year: 2021

description: Fire accidents involving Lithium-ion batteries (LIBs) threaten the safety of their storage facilities, where there are thousands of open-circuit cells stacked together forming ensembles. Ignition of ensembles could be triggered by self-heating but this important ignition phenomenon has received little attention in the literature. A few studies have investigated the self-heating of a single cell, but do not account for the effect of heat transfer. However, a large-size open-circuit LIB ensemble during storage can develop temperature gradients and therefore ignition is affected by both heat transfer and chemistry. In this thesis, I conducted ignition and calorimetry experiments using a commercial type of prismatic LiCoO2 cell to quantify self-heating conditions and find the chemical kinetics and thermal properties. Results show that self-heating ignition is possible when cells are stacked together and that the critical ambient temperature decreases with the number of cells. A computational model, based on open-source code Gpyro, is used to understand and predict ignition in different ensemble sizes and storage conditions. I used both ignition experiments and model predictions to quantify and compare two critical temperatures: the cell thermal runaway temperature defined in standard SAE-J2464, and the critical ambient temperature triggering ignition. I find that the cell thermal runaway temperature is insensitive to size, but the critical ambient temperature decreases with size. This shows that the critical ambient temperature should be used to design safe storage rather than the SAE standard. I further use the experiments and computational model to predict LIB ignition during storage with different states of charge and cathode materials. In order to understand whether the accelerating rate calorimetry (ARC) can properly quantify self-heating ignition, for the first time, I quantify the uncertainty caused by ignoring heat transfer in experiments. ARC can generally measure the onset of self-heating, but underestimate the heat of reaction, the maximum temperature and cannot measure critical ignition temperature. The results in this thesis help improve the safety of the open-circuit LIB storage and provide a scientific understanding of self-heating hazards and guidance for better standards.

Investigation into adaptive slicing methodologies for additive manufacturing
Creators: name: Yang, Qinkai
Publisher: name: Imperial College London
Year: 2021

description: Adaptive slicing is a methodology used to optimise the trade-off between build-time reduction and geometric accuracy improvement in additive manufacturing (AM). It works by varying decreasing layer thickness in sections of high curvature. However, current adaptive slicing methodologies all face the difficulty of adjusting layer thickness precisely according to the variations of the model’s geometry, thereby limiting the geometric accuracy improvement. This thesis tackles this difficulty by indicating the geometric variations of the model by evaluating the ratio of the volume of each sliced layer’s geometric deviation to the volume of its corresponding region in the digital model. This indication is accomplished because all the topological information of the corresponding region is considered in assessing the geometric deviation (volume) between each sliced layer and its corresponding region. Through having this precise indication to modify each layer thickness, this thesis aims to develop an adaptive slicing that can mitigate geometric inaccuracies (e.g. staircase effect and dimensional deviation) while balancing the build time. This slicing is evaluated using six different test models, compared with three current slicing methodologies (voxelisation-based, cusp height-based, and uniform slicing), and validated through computation and manufacturing. These validations all demonstrate that volume deviation-based slicing optimises the trade-off between build-time reduction and geometric accuracy improvement better than the other existing slicing methodologies. For example, it can reduce the build time by nearly half compared to other existing slicing methodologies assuming a similar degree of printed parts’ geometric accuracy. The improved trade-off optimised by volume deviation-based slicing can directly benefit the AM applications in the aerospace and medical industries. This is because current research has shown geometric inaccuracies are the primary cause of reducing energy efficiency (e.g. turbine blade and wind tunnel testing models) and having failed implants (e.g. hip and cranial implants, dental prostheses). In addition to improving the geometric accuracy of AM-constructed parts, volume deviation-based slicing may also be incorporated with non-planar layer slicing. Non-planar layer slicing is designed to mitigate the mechanical anisotropy of printed parts by using curved-sliced layers. By integrating volume deviation-based slicing with non-planar layer slicing, the thickness of each curved-sliced layer can be adjusted according to the model’s geometric variations and, therefore, has a possibility of reducing the geometric inaccuracies and mechanical anisotropy simultaneously.
Dynamical evolution of the Gliese 436 planetary system - Kozai migration as a potential source for Gliese 436b's eccentricity

description: The close-in planet orbiting GJ 436 presents a puzzling orbital eccentricity considering its very short orbital period. Given the age of the system, this planet should have been tidally circularized a long time ago. Many attempts to explain this were proposed in recent years, either involving abnormally weak tides, or the perturbing action of a distant companion. We address here the latter issue based on Kozai migration. We propose that GJ 436b was formerly located further away from the star and that it underwent a migration induced by a massive, inclined perturber via Kozai mechanism. In this context, the perturbations by the companion trigger high amplitude variations to GJ 436b that cause tides to act at periastron. Then the orbit tidally shrinks to reach its present day location. We numerically integrate the 3-body system including tides and General Relativity correction. We first show that starting from the present-day location of GJ 436b inevitably leads to damping the Kozai oscillations and to rapidly circularizing the planet. Conversely, starting from 5-10 times further away allows the onset of Kozai cycles. The tides act in peak eccentricity phases and reduce the semi-major axis of the planet. The net result is an evolution characterized by two phases: a first one with Kozai cycles and a slowly shrinking semi-major axis, and a second one once the planet gets out of the Kozai resonance characterized by a more rapid decrease. The timescale of this process appears in most cases much longer than the standard circularization time of the planet by a factor larger than 50. This model can provide a solution to the eccentricity paradox of GJ 436b. Depending on the various orbital configurations, it can take several Gyrs to GJ 436b to achieve a full orbital decrease and circularization. According to this scenario, we could be witnessing today the second phase of the scenario where the semi-major axis is already reduced while the eccentricity is still significant. We then explore the parameter space and derive in which conditions this model can be realistic given the age of the system. This yields constraints on the characteristics of the putative companion.

Spectral description of fluctuating electromagnetic fields of solids including a self consistency

Publisher: name: arXiv

description: Another way to evaluate the spectral-correlation properties of thermal fields of solids is suggested. Such a method takes into account detailed structure of the interface transition layer separating one bulk region from those of the vacuum region. The principal element here is the surface linear response function of an arbitrary inhomogeneous electron subsystem of solids. Along with straightforward using the known response functions, for example in a hydrodynamic approach, the suggested method allows calculating the response functions self-consistently based on the time dependent density functional theory. The self-consistent calculation of the linear response function followed by an application of the fluctuation-dissipation theorem yield in the spectral power densities of the fluctuating charge and current correlation functions. The final step of this sequence of actions aiming in obtaining the spectral-correlation properties of thermal fields of solids at any distances.

A new approach to the fault location problem: using the fault's transient intermediate frequency response
Creators: name: Cifuentes, Nicolas
Publisher: name: Imperial College London
Year: 2021

description: The fault location problem has been tackled mainly through impedance-based techniques, the travelling wave principle and more recently by machine learning algorithms. These techniques require both current and voltage measurements. In the case of impedance-based methods they can provide multiples solutions. In the case of the travelling wave approach it usually requires high sampling and synchronized frequency measurements together with sophisticated identification algorithms. Machine learning techniques require training data and re-tuning for different grid topologies. In this work we propose a new fault location method based on the fault's transient intermediate frequency response of the system immediately after a fault occurs. The transient response immediately after the occurrence of a fault is characterized by the travelling wave phenomenon together with intermediate frequencies of oscillation in the range of 5 to 500 kHz. These intermediate frequencies of oscillations are associated with the natural response of the cable/line system to the fault event. Their frequencies of oscillation are dependent on the faulted section and the fault location within that section. The proposed fault location methodology aims to leverage on that dependency, by firstly identifying these intermediate frequencies for different fault location scenarios for a given network. This process is performed offline using a linear time invariant (LTI) representation of the network. To compute this LTI representation, as part of this work an impedance representation in the modal domain is established for cable/line sections, which is able to capture the frequency-dependence and distributed nature of its electrical parameters. The offline methodology identifies these intermediate frequencies for different fault location scenarios, and then proceeds to fit the fault location dependence of each intermediate frequency using a polynomial regression. An online methodology is also proposed to perform the fault location in real time by solving the polynomial regressions computed during the offline methodology using measurements of the intermediate frequencies present in the frequency spectrum of transient signals. The fault location is thus solved by using voltage or current measurements of the fault’s transient response at different locations in the network, together with simple signal processing techniques such as the Fast Fourier Transform. The full method is tested with an EMT simulation in PSCAD, using the detailed frequency dependent model for underground cables, together with realistic load models in a low voltage distribution network test system.

description: High quality Bi2Te3 and Sb2Te3 topological insulators films were epitaxially grown on GaAs (111) substrate using solid source molecular beam epitaxy. Their growth and behavior on both vicinal and non-vicinal GaAs (111) substrates were investigated by reflection high-energy electron diffraction, atomic force microscopy, x-ray diffraction, and high resolution transmission electron microscopy. It is found that non-vicinal GaAs (111) substrate is better than a vicinal substrate to provide high quality Bi2Te3 and Sb2Te3 films. Hall and magnetoresistance measurements indicate that p type Sb2Te3 and n type Bi2Te3 topological insulator films can be directly grown on a GaAs (111) substrate, which may pave a way to fabricate topological insulator p-n junction on the same substrate, compatible with the fabrication process of present semiconductor optoelectronic devices.

description: Research has suggested that conceptual processing depends on both language-based and sensorimotor information. In this thesis, I investigate the nature of these systems and their interplay at three levels of the experimental structure—namely, individuals, words and tasks. In Study 1, I contributed to a multi-lab replication of the object orientation effect, which has been used to test sensorimotor simulation. The effect did not appear across any of the 18 languages examined, and it was not influenced by individual differences in mental rotation. Next, in Study 2, we drew on three existing data sets that implemented semantic priming, semantic decision and lexical decision. We extended these data sets with measures of language-based and vision-based information, and analysed their interactions with participants’ vocabulary size, gender and presentation speed. The analysis had a conservative structure of fixed and random effects. First, we found that language-based information was found to be more important than vision-based information. Second, in the semantic priming study—whose task required distinguishing between words and nonwords—, both language-based and vision-based information were more influential when words were presented faster. Third, a ‘task-relevance advantage’ was identified in higher-vocabulary participants. Specifically, in lexical decision, higher-vocabulary participants were more sensitive to language-based information than lower-vocabulary participants. In contrast, in semantic decision, higher-vocabulary participants were more sensitive to word concreteness. Fourth, we demonstrated the influence of the analytical method on the results. Last, we estimated the sample size required to investigate various effects. We found that 300 participants were sufficient to examine the effect of language-based information in words, whereas more than 1,000 participants were necessary for the effect of vision-based information and for the interactions of both former variables with vocabulary size, gender and presentation speed. This power analysis reveals the need to increase sample sizes for research on perceptual simulation and individual differences.

description: We study the consequences of dissipation in homogeneous media when the system is subject to a sudden change, thereby producing pairs of correlated quasi-particles with opposite momenta. We compute both the modifications of the spectrum, and those of the correlations. In particular, we compute the final coherence level, and identify the regimes where the state is non-separable. To isolate the role of dissipation, we first consider dispersive media and study the competition between the intensity of the jump which induces some coherence, and the temperature which reduces it. The contributions of stimulated and spontaneous emission are clearly identified. We then study how dissipation modifies this competition.

description: Bryozoans are mostly sessile colonial invertebrates that inhabit all kinds of aquatic ecosystems. Extant bryozoan species fall into two clades with one of them, Phylactolaemata, being the only exclusively freshwater clade. Phylogenetic relationships within the class Phylactolaemata have long been controversial owing to their limited distinguishable characteristics that reflect evolutionary relationships. Here, we present the first phylogenomic analysis of Phylactolaemata using transcriptomic data combined with dense taxon sampling of six families to better resolve the interrelationships and to estimate divergence time. Using maximum-likelihood and Bayesian inference approaches, we recovered a robust phylogeny for Phylactolaemata in which the interfamilial relationships are fully resolved. We show Stephanellidae is the sister taxon of all other phylactolaemates and confirm that Lophopodidae represents the second offshoot within the phylactolaemate tree. Plumatella fruticosa clearly falls outside Plumatellidae as previous investigations have suggested, and instead clusters with Pectinatellidae and Cristatellidae as the sister taxon of Fredericellidae. Our results demonstrate that cryptic speciation is very likely in F. sultana and in two species of Plumatella (P. repens and P. casmiana). Divergence time estimates show that Phylactolaemata appeared at the end of the Ediacaran and started to diverge in the Silurian, although confidence intervals were large for most nodes. The radiation of most extant phylactolaemate families occurred mainly in the Paleogene and Neogene highlighting post-extinction diversification.

description: We report on the gold assisted epitaxial growth of Ge nanostructures under ultra high vacuum (UHV) conditions (\approx3\times 10-10 mbar) on clean Ge (100) surfaces. For this study, \approx2.0 nm thick Au samples were grown on the substrate surface by molecular beam epitaxy (MBE). Thermal annealing was carried out inside the UHV chamber at temperature \approx500°C and following this, well ordered gold nanostructures placed on pedestal Ge were formed. A \approx 2 nm Ge film was further deposited on the above surface while the substrate was kept at a temperature of \approx 500°C. The height of the Ge (pedestal) underneath gold increased along with the formation of small Ge islands. The effect of substrate temperature and role of gold on the formation of above structures has been discussed in detail. Electron microscopy (TEM, SEM) studies were carried out to determine the structure of Au - Ge nano systems.

Two methods are explained and elaborated. One approach uses complex analysis to study a holomorphic function whose zeros can be identified with the eigenvalues of the linear operator. The second method is an operator theoretic approach involving the numerical range. General results obtained by the two methods are derived and compared. Applications to non-selfadjoint Jacobi and Schrödinger operators are considered. Some possible directions for future research are discussed.

In this paper, the capability of a hybrid genetic algorithm (HGA) to track the optimum in some dynamic environments is investigated for different functional dimensions, update frequencies, and displacement strengths in different types of dynamic environments. Experimental results are reported by using the HGA and some other existing evolutionary algorithms in the literature. The results show that the HGA has better capability to track the dynamic optimum than some other existing algorithms.

description: We show that the chiral kagome ice manifold exhibits an anomalous integer quantum Hall effect (IQHE) when coupled to itinerant electrons. Although electron-mediated interactions select a magnetically ordered ground state, the full ice manifold can coexist with the IQHE over a range of finite temperatures. The degenerate ice states provide a natural realization of power-law correlated flux disorder, for which the spectral gap of the system remains robust. The quantized (up to exponentially small finite-temperature corrections) Hall conductance persists over a wide range of electron densities due to the disorder-induced localization of electronic states.

description: Barrierefreiheit im Sinne (räumlicher) Anpassung an heterogene Schülerschaften wurde bislang kaum an Schulen bzw. konkret im Technikunterricht erforscht. In dieser Arbeit wurden 5 Potsdamer Grundschulen unter dem Siegel „Schule des gemeinsamen Lernens“ unter dem Aspekt der Barrierefreiheit in technischen Fachräumen untersucht. Die Arbeit erfasst den Ist-Zustand über Einrichtung und Ausstattung technischer Fachräume an oben genannten Potsdamer Schulen und zeigt gleichzeitig verschiedene Fachraumkonzepte auf. Hierzu wurden technische Fachräume zum einen auf barrierefreie Elemente untersucht und zum anderen von WAT-Fachlehrkräften in Hinblick auf ihre Barrierefreiheit bewertet.

String moduli inflation: An overview

subject: moduli: Kaehler
subject: vacuum state: de Sitter
subject: inflation: model
subject: inflaton

description: We present an overview of inflationary models derived from string theory focusing mostly on closed string moduli as inflatons. After a detailed discussion of the eta-problem and different approaches to address it, we describe possible ways to obtain a de Sitter vacuum with all closed string moduli stabilised. We then look for inflationary directions and present some of the most promising scenarios where the inflatons are either the real or the imaginary part of Kaehler moduli. We pay particular attention on extracting potential observable implications, showing how most of the scenarios predict negligible gravitational waves and could therefore be ruled out by the Planck satellite. We conclude by briefly mentioning some open challenges in string cosmology beyond deriving just inflation.
The relation between morphology, accretion modes and environmental factors in local radio AGN

description: The goal of this work is to determine the nature of the relation between morphology and accretion mode in radio galaxies, including environmental parameters. The CoNFIG extended catalogue (improved by new Ks-band identifications and estimated redshifts from UKIDSS, and spectral index measurements from new GMRT observations) is used to select a sub-sample of 206 radio galaxies with z<0.3 over a wide range of radio luminosity, which are morphology-classified using the Fanaroff-Riley (FR) classification of extended radio sources. For each galaxy, spectroscopic data are retrieved to determine the high/low excitation status of the source, related to its accretion mode. Environmental factors, such as the host galaxy luminosity and a richness factor are also computed, generally using SDSS data.

description: In this paper, we calculated the branching ratios and direct CP violation of the four $B\to Kπ$ decays with the inclusion of all currently known next-to-leading order (NLO) contributions by employing the perturbative QCD (pQCD) factorization approach. We found that (a) Besides the 10% enhancement from the NLO vertex corrections, the quark-loops and magnetic penguins, the NLO contributions to the form factors can provide an additional $\sim 15%$ enhancement to the branching ratios, and lead to a very good agreement with the data; (b) The NLO pQCD predictions are $\acp^{dir}(B^0\to K^+π^-)=(-6.5\pm 3.1)%$ and $\acp^{dir}(B^+\to K^+ π^0)=(2.2\pm 2.0)%$, become well consistent with the data due to the inclusion of the NLO contributions.

title: Admittance Modeling for Elastic Thickness Across the Mars Crustal Dichotomy Boundary

description: We use a Bouguer mass-sheet approximation for spectral admittance and correlation modeling to estimate elastic thickness, crustal thickness, crustal density, and load density across the Mars crustal dichotomy boundary near the landing site of NASA’s InSight Lander. We derive and constrain the parameter ranges using RMS misfit between the observed and theoretical admittance and their error bars. Spherical cap windows of 15° (900 km) radius are used to study 15 locations in the Northern Lowlands, the Southern Highlands and near and on the boundary which suggest distinct, but not sharp, difference in lithospheric properties. Elastic thickness estimates range generally between 0 and 30km in the Northern Lowlands, between 0 and 50km in the South Highlands and between 0 and 40km on the boundary itself. Crustal density varies from generally 2300-2900kgm-3 in the Northern Lowlands to 2200-2500kgm-3 in the Southern Highlands with intermediate values of 2200-2600kgm-3 directly on the boundary. It was not possible to adequately constrain well the surface (load) density for any of regions studied. No elastic thickness estimates for this region were thicker than 50km and the elastic thickness was always smaller than the crustal thickness. This region of the Northern Lowlands could have originally had similar elastic thickness as the neighboring Southern Highlands, and the large impacts that re-molded the northern hemisphere into the Northern Lowlands may have also increased the crustal density and reduced elastic thickness. In a couple of locations on the Highlands, however, the elastic thickness is small and these parts could have been weakened by local tectono-thermal processes after the formation of the boundary.

Unraveling the Impact of Product Market Competition and Earnings Volatility on Zero Leverage Policies
Creators: name: Rahimzadeh, Alireza

description: This thesis investigates the relationship between product market competition and zero leverage behavior within firms, aiming to uncover how these dynamics interact. Additionally, it explores whether firms characterized by higher earnings volatility exhibit a more pronounced positive relationship between product market competition and the likelihood of adopting a zero-leverage strategy. To carry out this investigation, we employed product market competition data (Fluidity) from the Hoberg-Phillips Data Library and financial data from the Compustat (North America) database, spanning from 1989 to 2019. As product market competition intensifies, the probability of firms adopting a zero leverage policy increases. Furthermore, our research illuminates that the positive impact of heightened product market competition on the likelihood of zero leverage policies is accentuated in firms characterized by elevated levels of earnings volatility. This finding corroborates our initial hypothesis, substantiating the notion that increased competition significantly influences a company's earnings volatility. We also strengthened our analysis with insights from existing literature, underscoring how heightened earnings volatility intensifies the propensity to embrace a zero leverage policy. This study contributes insights to the literature, notably as the first to employ the interaction term between product market competition and earnings volatility in exploring these financial dynamics.
