description: The direct domain coupling of spontaneous ferroelectric polarization and net magnetic moment can result in giant magnetoelectric (ME) coupling, which is essential to achieve mutual control and practical applications of multiferroics. Recently, the possible bulk domain coupling, the mutual control of ferroelectricity (FE) and weak ferromagnetism (WFM) have been theoretically predicted in hexagonal LuFeO3. Here, we report the first successful growth of highly-cleavable Sc-stabilized hexagonal Lu0.6Sc0.4FeO3 (h-LSFO) single crystals, as well as the first visualization of their intrinsic cloverleaf pattern of vortex FE domains and large-loop WFM domains. The vortex FE domains are on the order of 0.1-1 μm in size. On the other hand, the loop WFM domains are ~100 μm in size, and there exists no interlocking of FE and WFM domain walls. These strongly manifest the decoupling between FE and WFM in h-LSFO. The domain decoupling can be explained as the consequence of the structure-mediated coupling between polarization and dominant in-plane antiferromagnetic spins according to the theoretical prediction, which reveals intriguing interplays between FE, WFM, and antiferromagnetic orders in h-LSFO. Our results also indicate that the magnetic topological charge tends to be identical to the structural topological charge. This could provide new insights into the induction of direct coupling between magnetism and ferroelectricity mediated by structural distortions, which will be useful for the future applications of multiferroics.

description: Traditional place categorization approaches in robot vision assume that training and test images have similar visual appearance. Therefore, any seasonal, illumination and environmental changes typically lead to severe degradation in performance. To cope with this problem, recent works have proposed to adopt domain adaptation techniques. While effective, these methods assume that some prior information about the scenario where the robot will operate is available at training time. Unfortunately, in many cases this assumption does not hold, as we often do not know where a robot will be deployed. To overcome this issue, in this paper we present an approach which aims at learning classification models able to generalize to unseen scenarios. Specifically, we propose a novel deep learning framework for domain generalization. Our method develops from the intuition that, given a set of different classification models associated to known domains (e.g. corresponding to multiple environments, robots), the best model for a new sample in the novel domain can be computed directly at test time by optimally combining the known models. To implement our idea, we exploit recent advances in deep domain adaptation and design a Convolutional Neural Network architecture with novel layers performing a weighted version of Batch Normalization. Our experiments, conducted on three common datasets for robot place categorization, confirm the validity of our contribution.

description: We investigate the impact of the far ultraviolet (FUV) heating rate on the stability of the three-phase interstellar medium using three-dimensional simulations of a $1$ kpc$^2$, vertically-extended domain. The FUV heating rate sets the range of thermal pressures across which the cold ($\sim10^2$ K) and warm ($\sim10^4$ K) neutral media (CNM and WNM) can coexist in equilibrium. Even absent a variable star formation rate regulating the FUV heating rate, the gas physics keeps the pressure in the two-phase regime: because radiative heating and cooling processes happen on shorter timescales than sound wave propagation, turbulent compressions tend to keep the interstellar medium within the CNM-WNM pressure regime over a wide range of heating rates. The thermal pressure is set primarily by the heating rate with little influence from the hydrostatics. The vertical velocity dispersion adjusts as needed to provide hydrostatic support given the thermal pressure: when the turbulent pressure $\langleρ\rangleσ_z^2$ is calculated over scales $\gtrsim500$ pc, the thermal plus turbulent pressure approximately equals the weight of the gas. The warm gas volume filling fraction is $0.2

Resolving the effects of Data Deficient species on the estimation of extinction risk

Publisher: name: Imperial College London

description: Cost-effective reduction in the uncertainty surrounding global indicators of biodiversity change is a central goal of conservation. In this thesis, I identify and resolve the effects of IUCN Data Deficient species on the estimation of global patterns and levels of extinction risk. I show that gaps in our knowledge of species’ conservation status are primarily driven by spatial patterns of ecological research (Chapter 2). Large numbers of species are extremely poorly known, highlighting the importance of basic taxonomic and natural history information in conservation assessments. Using sensitivity analyses (Chapter 3), I show that Data Deficient species contribute to considerable uncertainty in patterns of extinction risk in freshwater invertebrates, limiting our understanding of the factors influencing extinction risks and our capacity to design reliable conservation schemes. To determine the likely conservation status of Data Deficient species, I develop seven machine learning models based on species’ life-history traits, niche and threat exposure (Chapter 4). I find that machine learning models accurately predict species conservation status and geographical patterns of threatened species richness. I predict 64% of Data Deficient mammals to be at risk of extinction, increasing the estimated proportion of threatened mammals from 22% to 27% globally. Finally, I use sampling theory to compare the cost-effectiveness of predictive models and IUCN Red List assessments in mammals, amphibians, reptiles and crayfish (Chapter 5). Double sampling with predictive models reduces the cost of determining the proportion of Data Deficient species at risk of extinction by up to 69%, and can be used to reduce the impact of uncertainty in the Red List and Red List Index. My thesis demonstrates how predictive models and decision theory can strengthen indicators of biodiversity change to monitor progress towards international biodiversity targets.

description: In this paper, the low-energy effective dynamics of M-theory, eleven-dimensional supergravity, is taken off-shell in a manifestly supersymmetric formulation. We show that a previously proposed relaxation of the superspace torsion constraints does indeed accommodate a current supermultiplet which lifts the equations of motion corresponding to the ordinary second order derivative supergravity lagrangian. Whether the auxiliary fields obtained this way can be used to construct an off-shell lagrangian is not yet known. We comment on the relation and application of this completely general formalism to higher-derivative (R^4) corrections. Some details of the calculation are saved for a later publication.

Background: Venus P-valveTM (Venus Medtech, Hangzhou, China) is a selfexpandablebioprosthetic valve that can be transcatheter-implanted in nativeright ventricular outflow tract (RVOT) patients. Valve implantation is technicallychallenging. Due to the implantation technique, left pulmonary artery (LPA) stentsrepresent a relative contraindication to Venus P-valve. In this case series, wedescribe our experience in implanting Venus P-valve in patients with previous LPAstents and the use of holographic models to facilitate procedural planning.Methods and results: From January to October 2023, 17 patients werescheduled for Venus P-Valve implantation. 16/17 (94%) patients weresuccessfully implanted. 3/16 (18.7%) patients underwent Venus P-valveimplantation with LPA stents. All patients underwent pre-operative CT scan.CT data set were employed to create three-dimensional (3D) holographicmodels (Artiness, Milan, Italy) of the entire heart, which were useful to planvalve implantation with a modified technique. Procedural success rate was100%. No procedural complications occurred. All three patients presentedgood haemodynamic and angiographic results at discharge and follow-up visits.Conclusion: This case-series underscores the feasibility of Venus P-valveimplantation in patients with previous LPA stents. The use of holographicmodels facilitated procedural planning in these challenging anatomical scenarios.
Infrared Excess and Molecular Clouds: A comparison of new suerveys of far-infrared and H I 21-cm emission at high galactic latitudes

description: We have created a map of the large-scale infrared surface brightness in excess of that associated with the atomic interstellar medium, using region-by-region correlations between the far-infrared and 21-cm line surface brightness. Our study updates and extends a previous attempt with IRAS and Berkeley/Parkes H I surveys. The far-infrared observations used here are from DIRBE, which extends far-infrared wavelength coverage to 240 um, so that we are reliably sampling the emission of large, thermal-equilibrium grains that dominate the dust mass. The H I data are from the combined Leiden-Dwingeloo and Parkes 21-cm line surveys. Using the maps of excess infrared emission at 100, 140, and 240 um, we created an atlas and identified the coherent structures. These infrared excess clouds can be caused both by dust that is warmer than average, or by dust associated with gas other than the atomic interstellar medium. We find very few warm clouds, such as the H II region around Spica. The majority of the infrared excess clouds are colder than the average atomic interstellar medium. These clouds are peaks of column density, and their excess infrared emission is due to dust associated with molecular gas. We identify essentially all known high-latitude molecular clouds in the infrared excess maps, and further identify a sample of new clouds with similar infrared properties. The infrared excess was correlated with CO line brightness, allowing us to measure the ratio of N(H2)/W(CO) for high-latitude clouds. The atlas of infrared excess may be a useful guide to regions of relatively high column density, which might cause high extinction toward extragalactic objects at optical and ultraviolet wavelengths and confusion for cosmic infrared and microwave backgrounds.

The Interferon Regulatory Factor 5 (IRF5) interactome: investigating the role of co-factors in regulation of inflammation
Creators: name: Eames, Hayley
Publisher: name: Imperial College London
Year: 2013

description: Interferon Regulatory Factor 5 (IRF5) is a key transcription factor that regulates inflammatory responses by acting as a mediator of macrophage plasticity. IRF5 is expressed at high levels in pro-inflammatory (M1) macrophages where it drives expression of characteristic M1 markers, such as IL-12p40, IL-12p35 and IL-23p19, and inhibits expression of typical markers of anti-inflammatory (M2) macrophages, like IL-10. In this way, IRF5 polarises macrophages towards a pro-inflammatory phenotype. There are two modes of IRF5 activity: 1) direct binding to Interferon Stimulated Response Element (ISRE) sites in the DNA, and 2) indirect recruitment via protein- protein interactions. IRF5 can be indirectly recruited via interactions with the RelA subunit of Nuclear Factor kappa B (NFκB) at multiple inflammatory loci genome- wide, including Tnf. This suggests protein-protein interactions between the two factors are of great importance for driving inflammatory gene expression. My research shows the IRF Association Domain (IAD) of IRF5 and the Dimerisation Domain (DD) of RelA form an interaction interface between the two proteins. I have identified a short peptide, a region of IRF5 IAD sequence, that can bind to RelA, and hypothesise this peptide could block IRF5-RelA interactions, potentially dampening expression of inflammatory mediators co-regulated by these two factors. I have also identified a novel co-factor of IRF5: Krüppel Associated Protein 1 (KAP1) by a proteomic screen consisting of affinity purification coupled to mass spectrometry. The IRF5-KAP1 complex is present in M1 macrophages, and absence of KAP1 in this cell type results in prolonged TNF secretion, suggesting that KAP1 is important for ‘switching off’ Tnf gene expression. Further investigation showed KAP1 is important for regulation of a heterochromatin (H3K9me3) environment downstream of the Tnf locus. By understanding the IRF5 interactome, we hope to unravel and potentially manipulate the determinants of IRF5’s key role in inflammation in a cell-type and activity-specific manner.

On the equivalence of fermionic string to bosonic string in two dimensions
Creators: name: Ishikawa, Hiroshi

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Two-dimensional fermionic string theory is shown to have a structure of topological model, which is isomorphic to a tensor product of two topological ghost systems independent of each other. One of them is identified with $c=1$ bosonic string theory while the other has trivial physical contents. This fact enables us to regard two-dimensional fermionic string theory as an embedding of $c=1$ bosonic string theory in the moduli space of fermionic string theories. Upon this embedding, the discrete states of $c=1$ string theory are mapped to those of fermionic string theory, which is considered to be the origin of the similarity between the physical spectra of these two theories. We also discuss a novel BRST operator associated with this topological structure.

All of the synthesized compounds exhibited moderate to good activity against the cancer cell lines selected. Particularly, Compound A5 showed the excellent potent activity against BPH-1 and MCF-7 with IC50 values of 10.4 and 9.1 μM, respectively, which is similar to doxorubicin (14.1 and 9.2 μM, respectively). As well as compound B6 exhibited most excellent activity toward PC12 with IC50 values of 16.4 μM. Compound A10 exhibited 55.4, 36.8 and 54.5 folds higher selectivity for BPH-1, PC12 and MCF-7 cells than for HEK-293 cell, respectively. In addition, theoretical biological activities of compounds A5 and A10 were evaluated by SwissADME.
Supramolecular self-assembly of single walled carbon nanotubes (SWNTs)
Creators: name: Yau, Hin Chun
Publisher: name: Imperial College London
Year: 2013

description: Applications of single walled carbon nanotubes (SWNTs) have been limited by their heterogeneity and the lack of selective assembly methodology. A selective SWNT junction formation was achieved by fullerene (C60) end-capped linker connecting SWNTs via their open ends. The SWNT junction was demonstrated in both single solvent (N-methyl pyrrolidone, NMP) and binary solvent mixtures (NMP and toluene). Initially, bis-fullerene linker was prepared following existing literature. However, spectroscopic characterisation revealed that the reaction between azide terminated PEG and C60 yield a novel closed ring structure rather than the linear dumbbell structure. The chain length of the PEG was found to be the key in the resulting structure of the adduct. Alternative synthetic methods were sought and the multifullerene end-capped linkers were synthesised via an one-step catalytic transesterification between polyethylene glycols (PEGs) and phenyl-C61-butyric acid methyl ester (PCBM) with a catalytic amount of dibutyltinoxide. Polydisperse and monodisperse branched PEGs were employed in the synthesis and purification was only achieved in the latter material. Both linear and star shape linkers were employed in the assembly process and the resulting SWNT junctions were characterised by atomic force microscopy (AFM). The SWNT junctions were found to be mainly localised on the body of the SWNT to give a ‘head-to-body’ assembly rather than the desired ‘head-to-head’ assembly, due to SWNT defects. While exploring the SWNT dispersion in organic solvents, a side reaction was observed during the sonication of NMP, causing significant contamination issues in AFM sample and high temperature annealing was found to be useful in improving sample quality. IR and UV-vis absorption spectroscopy revealed that NMP might polymerise during sonication, most likely due to amide bond cleavage. In addition, the resulting polyamide originated from NMP might play an important role in the dissolution of SWNT and other nanomaterials in amide solvents.

description: Direct UV-written waveguides are fabricated in silica-on-silicon with birefringence of $(4.9 \pm 0.2) \times 10^{-4}$, much greater than previously reported in this platform. We show that these waveguides are suitable for the generation of heralded single photons at telecommunication wavelengths by spontaneous four-wave mixing. A pulsed pump field at 1060 nm generates pairs of photons in highly detuned, spectrally uncorrelated modes near 1550 nm and 800 nm. Waveguide-to-fiber coupling efficiencies of 78-91% are achieved for all fields. Waveguide birefringence is controlled through dopant concentration of $\mathrm{GeCl_4}$ and $\mathrm{BCl_3}$ using the flame hydrolysis deposition process. The technology provides a route towards the scalability of silica-on-silicon integrated components for photonic quantum experiments.

description: A bimetallic Au-Pd catalyst supported on ceriazirconia with Au:Pd molar ratio 0.8 has been synthesized using a simultaneous deposition-precipitation method and oxidized at 250, 450, and 700 $^\circ$C in order to modify its particle size, nanostructure, and composition. Combined Xray energy dispersive spectroscopy and Xray photoelectron spectroscopy analysis clearly evidence that the bimetallic Au-Pd catalyst oxidized at 250 $^\circ$C is made up of a mixture of monometallic Au and Pd and bimetallic Au-Pd nanoparticles with Au:Pd ratios varying over a wide range. Increasing oxidation temperature leads to a stronger interaction between Au and Pd. Meanwhile, a slight increase of particle size and a narrowing of the Au:Pd ratio in the bimetallic nanoparticles take place. Compared with titania and activated carbon supports, the resistance against sintering at high temperatures of Au-Pd metal particles supported on ceriazirconia is proven to be higher. A synergistic effect has been observed for selective oxidation of benzyl alcohol on these catalysts. The catalytic activity decreases only slightly after oxidation at 450 $^\circ$C. However, oxidation at 700 $^\circ$C results in much lower catalytic activity. Migration of Pd onto Au particles during oxidation of benzyl alcohol enhances the catalytic activity of a physical mixture of monometallic Au and Pd supported on ceriazirconia catalysts. This fact, jointly with an analysis of the intrinsic activity, reveals the influence of the actual nature of Au-Pd interactions in the bimetallic particles, which points to higher activity of Au@Pd or Au@Pd@Pd nanostructures on ceria-zirconia support.

description: In today's logistics businesses, increasing petrol prices, fierce competition, dynamic business environments and volume volatility put pressure on logistics service providers (LSPs) or third party logistics providers (3PLs) to be efficient, differentiated, adaptive, and horizontally collaborative in order to survive and remain competitive. In this climate, efficient computerised-decision support tools play an essential role. Especially, for freight transportation, e efficiently solving a Pickup and Delivery Problem (PDP) and its variants by an optimisation engine is the core capability required in making operational planning and decisions. For PDPs, it is required to determine minimum-cost routes to serve a number of requests, each associated with paired pickup and delivery points. A robust solution method for solving PDPs is crucial to the success of implementing decision support tools, which are integrated with Geographic Information System (GIS) and Fleet Telematics so that the flexibility, agility, visibility and transparency are fulfilled. If these tools are effectively implemented, competitive advantage can be gained in the area of cost leadership and service differentiation. In this research, variants of PDPs, which multiple depots or providers are considered, are investigated. These are so called Multi-depot Pickup and Delivery Problems (MDPDPs). To increase geographical coverage, continue growth and encourage horizontal collaboration, efficiently solving the MDPDPs is vital to operational planning and its total costs. This research deals with designing optimisation algorithms for solving a variety of real-world applications. Mixed Integer Linear Programming (MILP) formulations of the MDPDPs are presented. Due to being NP-hard, the computational time for solving by exact methods becomes prohibitive. Several metaheuristics and hybrid metaheuristics are investigated in this thesis. The extensive computational experiments are carried out to demonstrate their speed, preciseness and robustness.

description: As part of program to quantize superstrings in AdS_5 x S^5 background in light cone approach we find the explicit form of the corresponding Green-Schwarz action in fermionic light-cone kappa-symmetry gauge. The resulting action is quadratic and quartic in fermions. In the flat space limit it reduces to the standard light-cone Green-Schwarz action, and also has the correct superparticle limit. We discuss fixing the bosonic light-cone gauge and a reformulation of the action in terms of 2-d Dirac spinors.

Large eddy simulation of coal combustion
Creators: name: Cavallo Marincola, Fabrizio
Publisher: name: Imperial College London
Year: 2013

description: In this work an in-house code for large-eddy simulations of coal combustion is developed and tested, with a special focus on the issue of modelling radiative heat transfer effects inside a furnace. An Eulerian-Lagrangian approach is used to describe the continuous gas phase and the discrete particle phase, with a two-way coupling between the two phases (implemented by another group member). The radiative transfer equation is solved using the discrete ordinates method, testing several different angular and spatial discretisation schemes. The spectral properties of the participating media are approximated with different grey gas models of varying complexity and accuracy. The accuracy of the radiative solver is initially assessed on simple idealised static cases in both two- and three-dimensions, and validated against benchmark data found in literature. The code is then integrated, parallelised and optimised with the LES flow and combustion solver, and used to simulate a large 2.4 MW coal combustion furnace. The results of the simulations are compared quantitatively against experimental data in terms of velocity, temperature, species distribution and solid particle analysis, showing a good agreement overall. A parametric study is then also performed on the variables and parameters of the radiation solver, showing great sensitivity on the outcome of the simulations in certain cases, further highlighting the importance of accurate radiation modelling for closed coal combustion furnaces.

Complex Velocity Fields in the Shell of T Pyxidis

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We present spatially-resolved, moderate-resolution spectrophotometry of the recurrent nova T Pyx and a portion of the surrounding shell. The spectrum extracted from a strip of width 10'' centered on the star shows well-known, strong emission lines typical of old novae, plus a prominent, unfamiliar emission line at 6590 Angstroms. This line, and a weaker companion at 6540 Angstroms which we also detect, have been previously reported by Shahbaz et al., and attributed to Doppler-shifted H alpha emission from a collimated jet emerging from T Pyx. We demonstrate that these lines are instead due to [NII] 6548, 6584 from a complex velocity field in the surrounding nebula. The comments of past workers concerning the great strength of HeII 4686 in T Pyx itself are also reiterated.

Determining the difference between local acceleration and local gravity: applications of the equivalence principle to relativistic trajectories
Creators: name: Balbus, Steven A.

description: We show by direct calculation that the common Equivalence Principle explanation for why gravity must deflect light is quantitatively incorrect by a factor of three in Schwarzschild geometry. It is therefore possible, at least as a matter of principle, to tell the difference between local acceleration and a true gravitational field by measuring the local deflection of light. We calculate as well the deflection of test particles of arbitrary energy, and construct a leading-order coordinate transformation from Schwarzschild to local inertial coordinates, which shows explicitly how the effects of spatial curvature manifest locally for relativistic trajectories of both finite and vanishing rest mass particles.

description: Anomaly cancellation for M-theory fivebranes requires the introduction of a "bump-form" which smoothes out the five-brane source. We discuss the physical origin of this bump-form in the simpler case of axion strings in 3+1 dimensions and construct it in terms of the radial profile of the fermion zero modes. Our treatment allows for a clearer understanding of the role played by covariant rather than consistent anomalies when anomalies are canceled by inflow from the bulk. We briefly discuss the generalization of these results to fivebrane anomalies in M theory.

$SU(n) \times \mathbb{Z}_2$ in F-theory on K3 surfaces without section as double covers of Halphen surfaces

description: We investigate F-theory models with a discrete $\mathbb{Z}_2$ gauge symmetry and $SU(n)$ gauge symmetries. We utilize a class of rational elliptic surfaces lacking a global section, known as Halphen surfaces of index 2, to yield genus-one fibered K3 surfaces with a bisection, but lacking a global section. We consider F-theory compactifications on these K3 surfaces times a K3 surface to build such models. We construct Halphen surfaces of index 2 with type $I_n$ fibers, and we take double covers of these surfaces to obtain K3 surfaces without a section with two type $I_n$ fibers, and K3 surfaces without a section with a type $I_{2n}$ fiber. We study these models to advance the understanding of gauge groups that form in F-theory compactifications on the moduli of bisection geometries. Our results also show that the Halphen surfaces of index 2 can have type $I_n$ fibers up to $I_9$. We construct an example of such a surface and determine the complex structure of the Jacobian of this surface. This allows us to precisely determine the non-Abelian gauge groups that arise in F-theory compactifications on genus-one fibered K3 surfaces obtained as double covers of this Halphen surface of index 2, with a type $I_9$ fiber times a K3 surface. We also determine the $U(1)$ gauge symmetries for compactifications when K3 surfaces as double covers of Halphen surfaces with type $I_9$ fiber are ramified over a smooth fiber.

The breeding ecology of the blue tit in relation to temperature microclimate
Creators: name: Bell, Sophie Cressida
Publisher: name: Imperial College London
Year: 2014

description: With warmer springs we observe earlier Spring phenologies. Long-term trends for earlier phenologies in warmer years have been demonstrated using population mean responses against temporal, altitudinal and latitudinal gradients. Temperature driven changes in phenology are measurable in a model system such as the oak-caterpillar-blue tit and the degree of change from one trophic level to the next can be compared across the network. The majority of studies on such a system focus on population mean trends. In this study I construct a geospatial model of temperature microclimates and test if variation in the phenologies of the simple oak, caterpillar, blue tit ecological network corresponds to variation in temperature across a single study site. Temperature traces are predicted with relative ease to a robust degree using the statistical modelling approach and given the known environmental, seasonal and synoptic weather trends for the location and time of interest. A microclimate modelling approach removes the constraint of a restricted temperature data-collection period and data is not limited to the site or position of the logger. This enables the comparison of behavioural responses amongst individuals as well as within individuals. I demonstrate that similar patterns of phenology are observed across the microclimates of a single study system as are observed for the same study system over time. More importantly by creating individual-specific temperature profiles I am able to compare the phenologies at each stage of the network to different temperature regimes as they occur under natural conditions. I find that not only do the three trophic levels differ in their periods of sensitivity to temperature change, but also that within these time-windows the phenologies of the tree, herbivore and bird are associated with differing temperature parameters. In addition to an effect on the timing of breeding, I also find an effect of microclimate temperature on incubation behaviour and female condition across the breeding effort. Climate change can lead to the uncoupling of links within ecological networks, known as trophic mismatch, as the environment of cue perception becomes disassociated from the environment of peak energy demand and selection. Given that the different trophic levels are sensitive to temperature change during different phases of Spring, I explicitly test whether temperature regimes are consistent across the Spring season and what impact differing temperatures between phases has on the breeding success of the apex predator. I find that not only are different temperature parameters not collinear, but that temperature changes are not concomitant across the Spring season. I therefore find support for the theory that trophic mismatch and blue tit nesting success is not just driven by warming temperatures, but by when temperature change occurs.

description: We study the formation of vacuum condensates in $2+1$ dimensional QED in the presence of inhomogeneous background magnetic fields. For a large class of magnetic fields, the condensate is shown to be proportional to the inhomogeneous magnetic field, in the large flux limit. This may be viewed as a {\it local} form of the {\it integrated} degeneracy-flux relation of Aharonov and Casher.
