description: We extend the Mellin representation of conformal field theory (CFT) to allow for conformal boundaries and interfaces. We consider the simplest holographic setup dual to an interface CFT - a brane filling an $AdS_{d}$ subspace of $AdS_{d+1}$ - and perform a systematic study of Witten diagrams in this setup. As a byproduct of our analysis, we show that geodesic Witten diagrams in this geometry reproduce interface CFT$_d$ conformal blocks, generalizing the analogous statement for CFTs with no defects.

description: The visual archives of the Nazi-Camps include SS photos and film footage, as well as those later produced by the Allies, but also the drawings, sketches and handicrafts produced by prisoners in the camps or after the war. My thesis focuses specifically on those drawings, made secretly by prisoners in the Ravensbrück and Neuen¬gamme Concentration Camps and also shortly after their survival/liberation. Microhistorical study of the prisoners' experiences in and their perspectives on the camps remains an important gap in the historiography of everyday-life in the camps. The visual perspective of the victims has to be considered as a serious and complex cluster of source material. These artefacts offer a wide range of subjective interpretations of social relations, diverse cultural practices and the everyday-life in the camps.

 In my thesis, I analyze the different functions drawings had, e.g., their social, communicative, and mnemonic or memorial functions. Further, I discuss strategies, continuities, and changes in the visual narratives about different aspects of everyday-life in the camps. Finally, I shed light on selected processes of transmission and reception/perception of theses drawings after 1945: their use and re-uses in collections, exhibitions, and trials.
Characterisation of STRO-1 expression on human mesenchymal stem cells and identification of putative cancer stem cells in osteosarcoma: prevention by micronutrients
Creators: name: Fawdar, Shameem
Publisher: name: University of Westminster

description: It is becoming increasingly more common to use culture expanded human mesenchymal stem cells (hMSCs) in regenerative medicine due to their low incidence in vivo. However, their successful application is hampered by a lack of selective markers to positively identify the expanded multipotent cells. This study aimed to characterise STRO-1 antigen as a potential biomarker of multipotency on cultured bone marrow derived hMSCs. In an attempt to identify the nature of this antigen, two techniques were implemented: peptide phage display technology and a microarray based approach. Changes in the expression of STRO-1 were investigated during culture expansion of hMSCs. STRO-1 expression positively correlated with cellular morphology and multilineage potential, whereby senescent cells down-regulated STRO-1 antigen and exhibited decreased adipogenic and osteogenic potential. Furthermore, STRO-1 was found to be heterogeneously expressed on hMSC populations and enrichment followed by lineage specific induction of the STRO-1BRIGHT fraction resulted in enhanced adipogenic and osteogenic differentiation potential. The expression of STRO-1 antigen was further characterised as a marker of differentiation, whereby differentiating cells were found to down-regulate STRO-1. A cellular hierarchy in hMSC population was therefore proposed based on STRO-1 status, with the highest STRO-1 expressive cells representing the multipotent subset. In an attempt to identify the epitope that STRO-1 IgM antibody recognised, peptide phage display technology was used as solid and liquid phase panning systems but the approach yielded no promising peptide candidate. Subsequently, comparative gene expression microarray analysis of osteosarcoma cell lines (143B, CAL72, G-292, HOS, MG-63, Saos-2 and U-2-OS) was implemented and a list of eight potential candidate genes encoding STRO-1 antigen was selected. This work ultimately led to the identification of putative cancer stem cells (CSCs) in seven osteosarcoma cell lines initially based on STRO-1 expression. With MG-63 strongly expressing STRO-1, the maintenance of MSC-like properties by STRO-1 expressing cell lines was investigated. A heterogeneous pattern of osteogenic differentiation was observed between and within the cell lines. Closer inspection revealed a cellular hierarchy comprising of holoclones and paraclones, with the holoclones representing the putative CSCs in osteosarcoma. Overall, this thesis addressed the fields of regenerative medicine as well as oncology by proposing STRO-1 antigen as a marker of multipotency on hMSCs and osteosarcoma holoclonal cells as the putative cancer stem cell targets for anti-cancer drug development.

description: Convolutional neural networks (CNNs) have demonstrated remarkable results in image classification for benchmark tasks and practical applications. The CNNs with deeper architectures have achieved even higher performance recently thanks to their robustness to the parallel shift of objects in images as well as their numerous parameters and the resulting high expression ability. However, CNNs have a limited robustness to other geometric transformations such as scaling and rotation. This limits the performance improvement of the deep CNNs, but there is no established solution. This study focuses on scale transformation and proposes a network architecture called the weight-shared multi-stage network (WSMS-Net), which consists of multiple stages of CNNs. The proposed WSMS-Net is easily combined with existing deep CNNs such as ResNet and DenseNet and enables them to acquire robustness to object scaling. Experimental results on the CIFAR-10, CIFAR-100, and ImageNet datasets demonstrate that existing deep CNNs combined with the proposed WSMS-Net achieve higher accuracies for image classification tasks with only a minor increase in the number of parameters and computation time.

description: Very strong magnetic fields can arise in non-central heavy-ion collisions at ultrarelativistic energies, which may not decay quickly in a conducting plasma. We carry out relativistic magnetohydrodynamics (RMHD) simulations to study the effects of this magnetic field on the evolution of the plasma and on resulting flow fluctuations in the ideal RMHD limit. Our results show that magnetic field leads to enhancement in elliptic flow for small impact parameters while it suppresses it for large impact parameters (which may provide a signal for initial stage magnetic field). Interestingly, we find that magnetic field in localized regions can temporarily increase in time as evolving plasma energy density fluctuations lead to reorganization of magnetic flux. This can have important effects on chiral magnetic effect. Magnetic field has non-trivial effects on the power spectrum of flow fluctuations. For very strong magnetic field case one sees a pattern of even-odd difference in the power spectrum of flow coefficients arising from reflection symmetry about the magnetic field direction if initial state fluctuations are not dominant. We discuss the situation of nontrivial magnetic field configurations arising from collision of deformed nuclei and show that it can lead to anomalous elliptic flow. Special (crossed body-body) configurations of deformed nuclei collision can lead to presence of quadrupolar magnetic field which can have very important effects on the rapidity dependence of transverse expansion (similar to {\it beam focusing} from quadrupole fields in accelerators).

description: The classification of crime into discrete categories entails a massive loss of information. Crimes emerge out of a complex mix of behaviors and situations, yet most of these details cannot be captured by singular crime type labels. This information loss impacts our ability to not only understand the causes of crime, but also how to develop optimal crime prevention strategies. We apply machine learning methods to short narrative text descriptions accompanying crime records with the goal of discovering ecologically more meaningful latent crime classes. We term these latent classes "crime topics" in reference to text-based topic modeling methods that produce them. We use topic distributions to measure clustering among formally recognized crime types. Crime topics replicate broad distinctions between violent and property crime, but also reveal nuances linked to target characteristics, situational conditions and the tools and methods of attack. Formal crime types are not discrete in topic space. Rather, crime types are distributed across a range of crime topics. Similarly, individual crime topics are distributed across a range of formal crime types. Key ecological groups include identity theft, shoplifting, burglary and theft, car crimes and vandalism, criminal threats and confidence crimes, and violent crimes. Though not a replacement for formal legal crime classifications, crime topics provide a unique window into the heterogeneous causal processes underlying crime.

description: A new method was developed for the simultaneous speciation analysis of inorganic arsenic (III, V), antimony (III, V) and selenium (IV, VI) in fluid samples by double-focusing sector field-inductively coupled plasma-mass spectrometry (SF-ICP-MS) coupled with high performance liquid chromatography (HPLC). A Hamilton PRX-X100 anion exchange column with EDTA (pH of 4.7) and 3% methanol as mobile phase was used for separation of the six species. The flow rate was set at 1.5 mL min−1. The overall analysis time was shortened down to within 11 minutes for all six desired species after a solvent gradient (linear ramp from 5 mM to 30 mM) was introduced in. The detection limits for As(III), As(V), Sb(III), Sb(V), Se(VI) and Se(IV) were 0.02 μg L−1, 0.06 μg L−1, 0.2 μg L−1, 0.02 μg L−1, 0.2 μg L−1 and 0.4 μg L−1 respectively, which were obtained from 11 replicate measurements of blank. The stability of retention time and linearity of calibration curve were also evaluated. Relative standard deviations (RSD) of ≤9% for retention times (at least 20 replicate measurements) and correlation coefficients (R2) of ≥0.9998 for calibration curves (at least 6 replicate experiments) were obtained. Finally, the proposed method was applied to the analysis of one synthetic sample, two hot spring samples and two certified reference materials. The results showed a good spike recovery, indicating that basically no mass loss occurred during chromatographic separation. For two certified reference materials, the detected results were in good agreement with the certified values.

description: The Drude-Smith model has been used extensively in fitting the THz conductivities of nanomaterials with carrier confinement on the mesoscopic scale. Here, we show that the conventional 'backscattering' explanation for the suppression of low-frequency conductivities in the Drude-Smith model is not consistent with a confined Drude gas of classical non-interacting electrons and we derive a modified Drude-Smith conductivity formula based on a diffusive restoring current. We perform Monte Carlo simulations of a model system and show that the modified Drude-Smith model reproduces the extracted conductivities without free parameters. This alternate route to the Drude-Smith model provides the popular formula with a more solid physical foundation and well-defined fit parameters.

description: The growing interest in the effectiveness of monetary policy has prompted an exploration of the role of trade credit in shaping the credit channel of policy transmission. Despite increased attention, a comprehensive theoretical model elucidating the observed empirical phenomenon—wherein trade credit mitigates the impact of central bank actions—has been lacking. This paper addresses this gap by introducing a partial equilibrium model integrating third-degree price discrimination with menu costs. The key finding suggests that the incremental increase in net present value (NPV) resulting from the optimization of credit terms and product prices is insufficient to offset even negligible menu costs associated with short-term interest rate adjustments during low-inflation periods. As a consequence, credit terms and product prices exhibit remarkable stability over time.

This outcome aligns coherently with the empirical evidence presented by Ng, Smith, and Smith (1999) and Mateut (2005), offering a theoretical foundation for the Meltzer (1960) hypothesis on the credit channel transmission of monetary policy. Specifically, our model implies that trade credit experiences less volatility than bank credit, rationalizing certain empirical phenomena related to the credit channel. In essence, firms strategically set trade credit terms to maximize NPV, taking into account the influence of menu costs.

Additionally, we discuss the implications of our findings on broader economic phenomena, drawing parallels to exchange rate pass-throughs and reflecting on the effectiveness of monetary easing in the context of a pandemic. By shedding light on the intricate interplay between trade credit, monetary policy, and menu costs, this research contributes to a deeper understanding of the mechanisms at play in the credit channel, thereby enriching the discourse on policy effectiveness in contemporary economic landscapes.

description: Numerical stochastic perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice field theory. The standard algorithms based on the Langevin equation, however, suffer from several limitations which in practice restrict the potential of this technique. In this work we investigate some alternative methods which could in principle improve on the standard approach. In particular, we present a study of the recently proposed Instantaneous Stochastic Perturbation Theory, as well as a formulation of numerical stochastic perturbation theory based on Generalized Hybrid Molecular Dynamics algorithms. The viability of these methods is investigated in $φ^4$ theory.

Recurrent AGN jet activity and feedback in galaxy groups
Creators: name: Brienza, Marisa
Publisher: name: Zenodo
Year: 2022

description: Jetted Active Galactic Nuclei (AGN) recurrently inflate lobes of relativistic plasma and magnetic fields, which rise buoyantly as light bubbles into the intragroup/intracluster medium, counterbalancing its spontaneous cooling. While the impact of jetted-AGN feedback is clear on energetic grounds, the exact physical mechanism that converts the bubble mechanical power into heat is not understood yet. One way to investigate this aspect is through the study of radio bubbles at late stages of their evolution, just before the complete mixing of the AGN plasma with the surrounding thermal gas. These have always been very difficult to identify but, thanks to the SKA precursors/pathfinders, in recent years we are taking major steps forward. In particular, observations in the MHz-frequency regime, have started unveiling the oldest plasma injected by AGN jets in their surrounding medium, providing new insights into the duty-cycle of AGN jets, as well as into the interaction between the AGN old plasma and the external thermal gas over timescales of hundreds of Myr. Here I will discuss two spectacular galaxy groups, Nest200047 and NGC507, whose radio (LOFAR/uGMRT) and X-ray (XMM-Newton/eROSITA) observations have recently given us an unprecedented detailed view of how the old AGN jet-inflated bubbles can get transported and dispersed throughout the system creating bizarre filamentary structures, which can give useful constraints to theoretical models of AGN feedback.

description: When performing statistical analysis of single-subject fMRI data, serial correlations need to be taken into account to allow for valid inference. Otherwise, the variability in the parameter estimates might be under-estimated resulting in increased false-positive rates. Serial correlations in fMRI data are commonly characterized in terms of a first-order autoregressive (AR) process and then removed via pre-whitening. The required noise model for the pre-whitening depends on a number of parameters, particularly the repetition time (TR). Here we investigate how the sub-second temporal resolution provided by simultaneous multislice (SMS) imaging changes the noise structure in fMRI time series. We fit a higher-order AR model and then estimate the optimal AR model order for a sequence with a TR of less than 600 ms providing whole brain coverage. We show that physiological noise modelling successfully reduces the required AR model order, but remaining serial correlations necessitate an advanced noise model. We conclude that commonly used noise models, such as the AR(1) model, are inadequate for modelling serial correlations in fMRI using sub-second TRs. Rather, physiological noise modelling in combination with advanced pre-whitening schemes enable valid inference in single-subject analysis using fast fMRI sequences.

Palestinian filmmaking in Israel: negotiating conflicting discourses
Creators: name: Friedman, Yael
Publisher: name: University of Westminster
Year: 2010

description: In recent years Palestinian cinema is evidently growing, as more films emerge from diverse sites of production: the Palestinian Authority, the different Palestinian diasporas and inside Israel. While scholars have often discussed Palestinian cinema without necessarily differentiating between the various sites of production, this thesis offers an in-depth analysis of Palestinian filmmaking inside Israel by Palestinians citizens of Israel. It addresses a lacuna in the research of Palestinian cinema by examining in detail the context of production of Palestinian films within the Israeli film industry, outlining the structural conditions and the discursive environment within which Palestinian filmmakers in Israel work. Moreover, through a close reading of key films, and references to others, this thesis identifies shared thematic characteristics of this body of work, and discusses the ways in which the films relate to both the Zionist and the Palestinian national discourses. Broadly, my analysis shows that while as with Palestinian cinema at large the films discussed in this thesis engage with issues of history, space and resistance they are nuanced in ways which relate to the specific circumstances of Palestinians in Israel. Concerns of ‘belonging’ and identity consume much of the films’ production and distribution processes as well as their thematic focus. Their production within Israel problematises the categories of both Israeli and Palestinian cinemas as ‘national’ cinemas, since their hybridity on the one hand exposes the ambivalence of the Zionist discourse and disturbs notions of Palestinian national resistance on the other. Thematically, many of the films’ narratives, especially of the younger generation, feature processes of ‘becoming’, as the films’ subjects search for places of belonging and identity positions. In so doing, the films often functioned as ‘sites’ through which conflicting discourses of identity, culture and politics were negotiated. In the films, and through the process of making the films, the filmmakers examined, scrutinized and often positioned themselves in relation to dominant Palestinian and Israeli/Zionist discourses, within the wider cultural trajectories of East and West.
A direct method to compute the galaxy count angular correlation function including redshift-space distortions

description: In the near future, cosmology will enter the wide and deep galaxy survey area allowing high-precision studies of the large scale structure of the universe in three dimensions. To test cosmological models and determine their parameters accurately, it is natural to confront data with exact theoretical expectations expressed in the observational parameter space (angles and redshift). The data-driven galaxy number count fluctuations on redshift shells, can be used to build correlation functions $C(θ; z_1, z_2)$ on and between shells which can probe the baryonic acoustic oscillations, the distance-redshift distortions as well as gravitational lensing and other relativistic effects. Transforming the model to the data space usually requires the computation of the angular power spectrum $C_\ell(z_1, z_2)$ but this appears as an artificial and inefficient step plagued by apodization issues. In this article we show that it is not necessary and present a compact expression for $C(θ; z_1, z_2)$ that includes directly the leading density and redshift space distortions terms from the full linear theory. It can be evaluated using a fast integration method based on Clenshaw-Curtis quadrature and Chebyshev polynomial series. This new method to compute the correlation functions without any Limber approximation, allows us to produce and discuss maps of the correlation function directly in the observable space and is a significant step towards disentangling the data from the tested models.

description: Light-element compounds hold great promise of high critical temperature superconductivity judging from the theoretical perspective. Hydrogen-rich material, benzene, is such a kind of candidate but also an organic compound. A series of first-principles calculations are performed on the electronic structures, dynamics properties, and electron-phonon interactions of solid benzene at high pressures. Benzene is found to be dynamically stable in the pressure range of 180 - 200 GPa and to exhibit superconductivity with a maximum transition temperature of 20 K at 195 GPa. The phonon modes of carbon atoms are identified to mainly contribute to the electron-phonon interactions driving this superconductivity. The predicted superconductivity in this simplest pristine hydrocarbon shows a common feature in aromatic hydrocarbons and also makes it a bridge to organic and hydrogen-rich superconductors.

These constants are used to show that Demailly's criterion for separation of higher-order jets by adjoint bundles also holds in positive characteristic. As an application, we give a characterization of projective space using Seshadri constants in positive characteristic, which was proved in characteristic zero by Bauer and Szemberg. We also discuss connections with other characterizations of projective space.

description: Motivated by recent experimental suggestions of charge-order-driven ferroelectricity in organic charge-transfer salts, such as $κ$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Cl, we investigate magnetic and charge-ordered phases that emerge in an extended two-orbital Hubbard model on the anisotropic triangular lattice at $3/4$ filling. This model takes into account the presence of two organic BEDT-TTF molecules, which form a dimer on each site of the lattice, and includes short-range intramolecular and intermolecular interactions and hoppings. By using variational wave functions and quantum Monte Carlo techniques, we find two polar states with charge disproportionation inside the dimer, hinting to ferroelectricity. These charge-ordered insulating phases are stabilized in the strongly correlated limit and their actual charge pattern is determined by the relative strength of intradimer to interdimer couplings. Our results suggest that ferroelectricity is not driven by magnetism, since these polar phases can be stabilized also without antiferromagnetic order and provide a possible microscopic explanation of the experimental observations. In addition, a conventional dimer-Mott state (with uniform density and antiferromagnetic order) and a nonpolar charge-ordered state (with charge-rich and charge-poor dimers forming a checkerboard pattern) can be stabilized in the strong-coupling regime. Finally, when electron-electron interactions are weak, metallic states appear, with either uniform charge distribution or a peculiar $12$-site periodicity that generates honeycomb-like charge order.

description: While the importance of principals as instructional leaders has established their key role in promoting high-quality teaching and learning in classrooms, there has been relatively limited research into STEM-specific instructional leadership. Principals as STEM Leaders – Building the Evidence Base for Improved STEM Learning (PASL) was undertaken to address this gap. PASL was a national research project conducted with Australian school principals and school leadership teams, aimed at building educational leadership capacity in STEM education. It has produced a set of three evidence-base professional learning programmes, co-designed with principals, to build capability to effectively drive whole-of-school collaborative effort in STEM teaching and learning. This report summarises the theoretical underpinning of the project and the approach to the creation and trial of the professional learning materials. The report also details the findings and recommendations drawn from research conducted as part of the PASL project. The PASL project was funded by the Department of Education, Skills and Employment (DESE) under the Inspiring all Australians in Digital Literacy and STEM – Embracing the Digital Age measure of the National Innovation and Science Agenda.

description: Let $I$ and $J$ be nonzero ideals in two Noetherian algebras $A$ and $B$ over a field $k$. Let $I+J$ denote the ideal generated by $I$ and $J$ in $A\otimes_k B$. We prove the following expansion for the symbolic powers: $$(I+J)^{(n)} = \sum_{i+j = n} I^{(i)} J^{(j)}.$$ If $A$ and $B$ are polynomial rings and if chara$(k) = 0$ or if $I$ and $J$ are monomial ideals, we give exact formulas for the depth and the Castelnuovo-Mumford regularity of $(I+J)^{(n)}$, which depend on the interplay between the symbolic powers of $I$ and $J$. The proof involves a result of independent interest which states that under the above assumption, the induced map Tor$_i^A(k,I^{(n)}) \to$ Tor$_i^A(k,I^{(n-1)})$ is zero for all $i \ge 0$, $n \ge 0$. We also investigate other properties and invariants of $(I+J)^{(n)}$ such as the equality between ordinary and symbolic powers, the Waldschmidt constant and the Cohen-Macaulayness.

description: In this paper we consider two kinds of noncommutative space-time commutation relations in two-dimensional configuration space and feature the absolute value of the minimal length from the generalized uncertainty relations associated to the particular commutation relations. We study the problem of the two-dimensional gravitational quantum well in the new Hermitian variables and confront the experimental results for the first lowest energy state of the neutrons in the Earth's gravitational field to estimate the upper bounds on the noncommutativity parameters. The absolute value of the minimum length is smaller than a few nanometers.

6D SCFTs and Phases of 5D Theories

description: Starting from 6D superconformal field theories (SCFTs) realized via F-theory, we show how reduction on a circle leads to a uniform perspective on the phase structure of the resulting 5D theories, and their possible conformal fixed points. Using the correspondence between F-theory reduced on a circle and M-theory on the corresponding elliptically fibered Calabi--Yau threefold, we show that each 6D SCFT with minimal supersymmetry directly reduces to a collection of between one and four 5D SCFTs. Additionally, we find that in most cases, reduction of the tensor branch of a 6D SCFT yields a 5D generalization of a quiver gauge theory. These two reductions of the theory often correspond to different phases in the 5D theory which are in general connected by a sequence of flop transitions in the extended Kahler cone of the Calabi--Yau threefold. We also elaborate on the structure of the resulting conformal fixed points, and emergent flavor symmetries, as realized by M-theory on a canonical singularity.

description: Recent progress in applying complex network theory to problems in quantum information has resulted in a beneficial crossover. Complex network methods have successfully been applied to transport and entanglement models while information physics is setting the stage for a theory of complex systems with quantum information-inspired methods. Novel quantum induced effects have been predicted in random graphs---where edges represent entangled links---and quantum computer algorithms have been proposed to offer enhancement for several network problems. Here we review the results at the cutting edge, pinpointing the similarities and the differences found at the intersection of these two fields.

Long term dynamics for the restricted N-body problem with mean motion resonances and crossing singularities

description: We consider the long term dynamics of the restricted N-body problem, modeling in a statistical sense the motion of an asteroid in the gravitational field of the Sun and the solar system planets. We deal with the case of a mean motion resonance with one planet and assume that the osculating trajectory of the asteroid crosses the one of some planet, possibly different from the resonant one, during the evolution. Such crossings produce singularities in the differential equations for the motion of the asteroid, obtained by standard perturbation theory. In this work we prove that the vector field of these equations can be extended to two locally Lipschitz-continuous vector fields on both sides of a set of crossing conditions. This allows us to define generalized solutions, continuous but not differentiable, going beyond these singularities. Moreover, we prove that the long term evolution of the 'signed' orbit distance (Gronchi and Tommei 2007) between the asteroid and the planet is differentiable in a neighborhood of the crossing times. In case of crossings with the resonant planet we recover the known dynamical protection mechanism against collisions. We conclude with a numerical comparison between the long term and the full evolutions in the case of asteroids belonging to the 'Alinda' and 'Toro' classes (Milani et al. 1989). This work extends the results in (Gronchi and Tardioli 2013) to the relevant case of asteroids in mean motion resonance with a planet.

description: We study the notion of robustness in stable matching problems. We first define robustness by introducing (a,b)-supermatches. An $(a,b)$-supermatch is a stable matching in which if $a$ pairs break up it is possible to find another stable matching by changing the partners of those $a$ pairs and at most $b$ other pairs. In this context, we define the most robust stable matching as a $(1,b)$-supermatch where b is minimum. We show that checking whether a given stable matching is a $(1,b)$-supermatch can be done in polynomial time. Next, we use this procedure to design a constraint programming model, a local search approach, and a genetic algorithm to find the most robust stable matching. Our empirical evaluation on large instances show that local search outperforms the other approaches.
