Stable isotope tracing of engineered nanoparticles
Creators: name: Laycock, Adam John
Publisher: name: Imperial College London
Year: 2014

description: Engineered nanoparticles (NPs) are increasingly being used in consumer products due to their novel properties. Consequently, concerns have been raised over the potential hazards that these materials may present as a result of their release into the natural environment. This has prompted numerous investigations into the environmental behavior, transport and fate of engineered NPs. Importantly the predicted environmental concentrations of these materials is often x10 to x100 lower than the natural background levels of the element. Many studies overcome this problem with the use of high dosing concentrations, however this raises concerns regarding environmental relevance. The work presented in this thesis demonstrates how stable isotope tracing enables the accurate detection and quantification of engineered NPs in complex biological samples even when exposures are performed at low and environmentally relevant concentrations. This thesis focuses on three of the most prominent commercially available NPs; ZnO, CeO2 and Ag, and covers all aspects of the application of stable isotope labeling and tracing for these materials. This includes; (i) an assessment and evaluation of the technique for application with CeO2 NPs, including the development of chemical separation and mass spectrometric methods for an environmental tracer study, (ii) the assessment of a synthesis protocol for the production of isotopically labeled Ag NPs, and (iii) two environmental tracer studies to assess the uptake and loss of Zn from ZnO NPs by an estuarine snail and earthworm.
A new analysis of the Red Giant Branch "Tip" distance scale and the value of the Hubble constant

description: The theoretical evaluations of the Red Giant Branch Tip (TRGB) luminosity presented in Salaris & Cassisi (1997) are extended to higher metallicities, and compared with analogous independent results recently published. The comparison between our ZAHB and TRGB distance scales for galactic globular clusters presented in Salaris & Cassisi (1997) is now supplemented with a comparison with the HIPPARCOS distance scale set by local subdwarfs with accurate parallax determinations. The overall agreement between ZAHB and HIPPARCOS distances is quite good. The ZAHB and TRGB distances to resolved galaxies are in good agreement, whereas the comparison between TRGB and Cepheid distances, computed by using the calibration suggested by Madore & Freedman (1991), reveals a systematic discrepancy of the order of 0.12 mag. The TRGB distances are systematically longer in comparison with the Cepheid ones. This result supports the case for a revision of the zero point of the Cepheid distance scale, as already suggested by other authors on the basis of HIPPARCOS parallaxes. The application of our TRGB distance scale to NGC3379, provides a new distance to the Leo I group, which coupled with recent independent determinations of the distance Coma cluster-Leo I, provides a determination of H_0 at the Coma cluster in the range: H_0= 60+-11 Km s^{-1} Mpc^{-1}.

description: We investigate the fractional diffusion approximation of a kinetic equation in the upper-half plane with diffusive reflection conditions at the boundary. In an appropriate singular limit corresponding to small Knudsen number and long time asymptotic, we derive a fractional diffusion equation with a nonlocal Neumann boundary condition for the density of particles. Interestingly, this asymptotic equation is different from the one derived by L. Cesbron in [7] in the case of specular reflection conditions at the boundary and does not seem to have receive a lot of attention previously.

description: Statistical properties of effective mass are analyzed. We show from a general ground that effective mass as a function of time should not exhibit long plateaux whatever high statistics simulations are made: the mass should fluctuate beyond the one standard deviation of error bars after a few time slices for large times where the ground state dominates. This explains the difficulty of obtaining long plateaux experienced in previous simulations. Implications of the observation for global $χ^2$ fits are discussed, and results for hadron masses are presented.

Quantitative methods for reconstructing protein-protein interaction histories
Creators: name: Topping, Ryan
Publisher: name: Imperial College London
Year: 2013

description: Protein-protein interactions (PPIs) are vital for the function of a cell and the evolution of these interactions produce much of the evolution of phenotype of an organism. However, as the evolutionary process cannot be observed, methods are required to infer evolution from existing data. An understanding of the resulting evolutionary relationships between species can then provide information for PPI prediction and function assignment. This thesis further develops and applies the interaction tree method for modelling PPI evolution within and between protein families. In this approach, a phylogeny of the protein family/ies of interest is used to explicitly construct a history of duplication and specification events. Given a model relating sequence change in this phylogeny to the probability of a rewiring event occurring, this method can then infer probabilities of interaction between the ancestral proteins described in the phylogeny. It is shown that the method can be adapted to infer the evolution of PPIs within obligate protein complexes, using a large set of such complexes to validate this application. This approach is then applied to reconstruct the history of the proteasome complex, using x-ray crystallography structures of the complex as input, with validation to show its utility in predicting present day complexes for which we have no structural data. The methodology is then adapted for application to transient PPIs. It is shown that the approach used in the previous chapter is inadequate here and a new scoring system is described based on a likelihood score of interaction. The predictive ability of this score is shown in predicting known two component systems in bacteria and its use in an interaction tree setting is demonstrated through inference of the interaction history between the histidine kinase and response regulator proteins responsible for sporulation onset in a set of bacteria. This thesis demonstrates that with suitable modifications the interaction tree approach is widely applicable to modelling PPI evolution and also, importantly, predicting existing PPIs. This demonstrates the need to incorporate phylogenetic data in to methods of predicting PPIs and gives some measure of the benefit in doing so.

description: We report the results of a 5-GHz southern-hemisphere snapshot VLBI observation of a sample of blazars. The observations were performed with the Southern Hemisphere VLBI Network plus the Shanghai station in 1993 May. Twenty-three flat-spectrum, radio-loud sources were imaged. These are the first VLBI images for 15 of the sources. Eight of the sources are EGRET (> 100 MeV) gamma-ray sources. The milliarcsecond morphology shows a core-jet structure for 12 sources, and a single compact core for the remaining 11. No compact doubles were seen. Compared with other radio images at different epochs and/or different frequencies, 3 core-jet blazars show evidence of bent jets, and there is some evidence for superluminal motion in the cases of 2 blazars. The detailed descriptions for individual blazars are given. This is the second part of a survey: the first part was reported by Shen et al. (AJ 114(1997)1999).

description: We first perform bosonic T-duality transformation on one of the marginal TsT (T-duality, shift, T-duality)-deformed $AdS_5\times S_5$ spacetime, which corresponds to 4D $\mathcal{N}=4$ non-commutative super Yang-Mills theory (NCSYM). We then construct the solution to killing spinor equations of the resulting background, and perform the fermionic T-duality transformation. The final dual geometry becomes the usual $AdS_5\times S_5$ but with the constant NS-NS B-field depending on the non-commutative parameter. As applications, we study the gluon scattering amplitude and open string (Wilson loop) solution in the TsT-deformed $AdS_5\times S_5$ spacetime, which are dual to the null polygon Wilson loop and the folded string solution respectively in the final dual geometry.

Pitfalls of a power-law parameterization of the primordial power spectrum for Primordial Black Hole formation

description: Primordial Black Holes (PBHs) can form in the radiation dominated early Universe from the collapse of large density perturbations produced by inflation. A power-law parameterisation of the primordial power spectrum is often used to extrapolate from cosmological scales, where the amplitude of the perturbations is well-measured by Cosmic Microwave Background and Large Scale Structure observations, down to the small scales on which PBHs may form. We show that this typically leads to large errors in the amplitude of the fluctuations on small scales, and hence extremely inaccurate calculations of the abundance of PBHs formed.

We show that the critical line at finite temperatures, defined to be the line of vanishing pion screening mass, turns back toward strong coupling, forming a cusp on the $(β, K)$ plane, and that the line of thermal transition runs past the tip of the cusp without touching the critical line. Previous results are discussed in the light of our findings.

description: We investigate whether the new horizon first law proposed recently still work in $f(R)$ theory. We identify the entropy and the energy of black hole as quantities proportional to the corresponding value of integration, supported by the fact that the new horizon first law holds true as a consequence of equations of motion in $f(R)$ theories. The formulas for the entropy and energy of black hole found here are in agreement with the results obtained in literatures. For applications, some nontrivial black hole solutions in $f(R)$ theories have been considered, the entropies and the energies of black holes in these models are firstly computed, which may be useful for future researches.

Development of fluorescence lifetime measurement techniques for use in microfluidic channels
Creators: name: Stapountzis, Margarita Antonia
Publisher: name: Imperial College London
Year: 2012

description: Fluorescence lifetime measurements are a powerful tool in biomedical research and advances in detection technology make them ideally suited for the study of biomolecular interactions. Time-resolved techniques, compared to more conventional methods, provide improved precision and contrast in the monitoring of complex biological processes. Fluorescence lifetimes are extracted by using time-correlated single-photon counting, which offers single photon sensitivity, high temporal resolution and excellent signal to noise ratio. Furthermore, combining this technique with microfluidics offers unprecedented advantages. For example, in analytical applications, apart from the high sensitivity required, the study of analytes often demands low sample consumption and short mixing times to allow for the monitoring of quick reactions. These parameters can nicely be achieved with the use of microfluidics. Hydrodynamic focusing within 3-inlet 1-outlet continuous flow microfluidic devices can be used as a molecular confinement mechanism to improve the detection efficiency as well as a means to enhance mixing within microchannels for the study of fast reaction kinetics. In this work, a powerful combination of confocal microscopy and microfluidics was used to perform fluorescence lifetime measurements on freely diffusing and freely flowing molecules. For this purpose, a home-built scanning confocal system was developed to ensure sufficient reduction in background levels, enabling the detection of fluorescence signal that arises from single molecules. Fluorescence lifetime imaging along with a maximum likelihood estimator adapted from single molecule studies was performed to visualise hydrodynamic focusing and characterise mixing within microfluidic devices. Time-resolved methods were also employed to detect single molecules freely flowing within microchannels. A novel fluorescence lifetime approach was developed to perform Förster resonance energy transfer measurements on freely diffusing molecules and subsequently applied for the study of streptavidin-biotin binding and protein conformational changes upon unfolding.

description: In 2016, Balakrishnan-Ho-Kaplan-Spicer-Stein-Weigandt produced a database of elliptic curves over $\mathbb{Q}$ ordered by height in which they computed the rank, the size of the $2$-Selmer group, and other arithmetic invariants. They observed that after a certain point, the average rank seemed to decrease as the height increased. Here we consider the family of elliptic curves over $\mathbb{Q}$ whose rational torsion subgroup is isomorphic to $\mathbb{Z}/2\mathbb{Z} \times \mathbb{Z}/8\mathbb{Z}$. Conditional on GRH and BSD, we compute the rank of $92\%$ of the $202461$ curves with parameter height less than $10^3$. We also compute the size of the $2$-Selmer group and the Tamagawa product, and prove that their averages tend to infinity for this family.

description: We estimate the energy release of black hole formation to the intra-cluster medium of the Coma cluster and find that this is comparable to the present day energy content. Therefore an energetic and maybe hydrostatic influence is possible. Our calculations rely on the assumption of an universal black hole to galaxy mass ratio (more exactly: spheroidal mass component of the stellar population), for which there is growing evidence. On a cosmological scale, there is also an energy release of black hole formation comparable to what is expected to be present within the thermal gas, caused by the process of structure formation. This indicates an important dynamical influence, neglected by present day structure formation simulations. This estimate of cosmological black hole energy release is independent of the black hole to galaxy mass ratio, but consistent with its value.

description: The study of the Cosmic Microwave Background (CMB) lensing potential has established itself by now as a robust way of probing the physics of large-scale structure growth. The most common estimators of the lensing potential are derived under the assumption of Gaussianity of the matter distribution and in the Born approximation of the photon diffusion. In this paper we study the performance of quadratic estimators when applied to realistic sky maps extracted from multiple-lens ray tracing techniques in cosmological $N$-body simulations. These are expected to model accurately the effects due to the non-Gaussianity of the matter distribution induced by its nonlinearity and the deviation from the Born approximation. We show that both these effects on their own lead to reconstruction biases, but these tend to partially cancel each other when both these effects are considered together. We forecast the impact of these biases on the estimation of cosmological parameters for future high-sensitivity CMB experiments like CMB-S4. We find that the cold dark matter density, $Ω_\textrm{cdm}$, the optical depth to reionization $τ$, the amplitude of primordial inflationary perturbations, $A_s$ and the sum of neutrino masses, $M_ν$, could be biased at the 1-2$σ$ level, if no external data set is used. We also observe a reduction of the bias if external data like baryon acoustic oscillations (BAO) is included.

Hierarchical Macroporous Polymers: Synthesis and Characterisation
Creators: name: Wong, Ling Ching
Publisher: name: Imperial College London
Year: 2013

description: This thesis describes the production of two types of hierarchical macroporous polymers using the emulsion templating technique. The first are those with a hierarchy of macroporous, defined as the efficient packing of pores with multi-modal pore size distributions. The second are macroporous polymers containing a hierarchical particulate network, defined by an interconnected particle network within the polymer matrix. In the first section of the thesis, macroporous hierarchy was achieved using 3 different methods. In the first method, the properties of surfactant stabilised high internal phase emulsion (HIPE) were optimised by varying selected emulsification parameters such as the surfactant concentration and stirring rate. The Finite Element Method (FEM) was subsequently used to qualitatively compare and validate the effect of pore hierarchy on the Young’s modulus of macroporous polymers. It was believed that the hierarchical arrangement of macropores facilitated the load transfer during compression, which improved its mechanical properties. The second method involved the use of a mixed surfactant and particle emulsifier system to prepare w/o HIPEs. The mixture of surfactants and particles in the emulsion produced synergistic effects which resulted in a hierarchical macroporous arrangement after polymerisation. The hierarchical porous materials prepared using this method showed high gas permeabilities while maintaining high crush strengths and Young’s moduli compared to ‘conventional’ poly(merised)HIPEs. The improvement in mechanical strength despite the high interconnectivity was attributed to the efficient packing of macropores in a hierarchical configuration. The third approach was to mechanically-froth viscous air in w/o emulsion templates. A bio-based monomer, acrylated epoxidised soyabean oil (AESO) was chosen as a component of the continuous phase of the emulsion for its high viscosity and ability to trap air bubbles during mechanical frothing. Medium Internal Phase Emulsions (MIPEs) containing varying concentrations of AESO were mechanically frothed to incorporate air bubbles, prior to polymerisation. This was found to generate a multi-modal distribution of droplets and air bubbles which polymerised into hierarchical foams with high porosities of up to 81%. In the second section of the thesis, a hierarchical particulate network within the polymer matrix of a porous material was produced using Pickering HIPEs stabilised by varying the concentrations of thermally reduced graphene oxide (rGO) flakes. Macroporous nanocomposites containing 0.006 vol.% of rGO had a conductivity of 1.2 10-5 Sm-1, demonstrating the presence of an interconnected, conducting rGO network within the polymer matrix. The rGO-network created an additional level of hierarchy in these macroporous materials which also improved the overall mechanical properties (viscoelastic properties, Young’s modulus and crush strength).

description: We study the Kitaev spin liquid (KSL) in a [001] magnetic field employing the mean field theory (MFT/MF) in the Majorana fermion representation. The MF Hamiltonian of the system has the Bogoliubov de-Gennes (BdG) form of a 2D Weyl superconductor. We discover a robust gapless regime in intermediate magnetic field for both gapless and gapped AFM KSL with Jx = Jy before the system is polarized in high magnetic field. A topological phase transition (PT) connecting two gapless phases with nodal lines takes place at a critical magnetic field hc1 in this regime. While the nodal lines at hc1 is protected by the mirror symmetry with Jx = Jy and disappear at Jx 6= Jy with a gap opening near the critical field, the nodal points at E = 0 can exist at intermediate fields even without mirror symmetry. We reveal that the phase evolution of the KSL in the magnetic field is driven by the competition between the magnetic field and the particle-hole (p-h) asymmetry of the normal state of the BdG Hamiltonian, which results in the robust intermediate gapless phase for AFM KSL. For FM KSL, there is no intermediate PT before polarization. The above phase diagrams are confirmed by dynamical MFT (DMFT) results.

description: Our objective is to compute the moments of the deep-inelastic structure functions of the nucleon on the lattice. A major source of uncertainty is the renormalization of the lattice operators that enter the calculation. In this talk we compare the renormalization constants of the most relevant twist-two bilinear quark operators which we have computed non-perturbatively and perturbatively to one loop order. Furthermore, we discuss the use of tadpole improved perturbation theory.

description: The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetisation of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically distinct sublattices, such as rare-earth transition-metal alloys, it depends on the difference between the sublattice contributions. Here we show that in a highly spin polarized, fully compensated ferrimagnet, where the sublattices are chemically similar, MOKE is observed even when the net moment is strictly zero. We analyse the spectral ellipsometry and MOKE of Mn 2 Ru x Ga, and show that this behaviour is due to a highly spin-polarized conduction band dominated by one of the two manganese sublattices which creates helicity-dependent reflectivity determined by a broad Drude tail. Our findings open new prospects for studying spin dynamics in the infra-red.

description: We report on mid-infrared (MIR) continuum and line emission mapping of the nucleus of NGC 253. The data, with a resolution of 1\as.4, reveal a double-peaked arc-like [NeII] emission region. Comparison with published data shows that the [NeII] arc is centered on the nucleus of the galaxy. The brightest [NeII] source coincides with the infrared continuum peak. The interpretation of these results is complicated by the edge-on orientation of NGC 253, but a self-consistent explanation is starformation triggered by dynamical resonances in a barred potential.

The Phase Structure of the Schwinger Model on the Lattice with Wilson Fermions in the Hartree-Fock Approximation

Year: 1995
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: The phase diagram of the Schwinger model on the lattice with one and two degenerate flavours of Wilson fermions is investigated in the Hartree-Fock approximation. In case of a single flavour (not directly amenable to numerical simulation), the calculation indicates the existence of the parity violating phase at both weak and intermediate-to-strong couplings. In the broken phase, the Hartree-Fock vacuum sustains a nonzero electric field. With two flavours, parity is not broken at weak coupling. However, both parity and flavour become spontaneously broken at the Hartree-Fock level as the coupling becomes strong.

Ground color stramineous infused with brown; anteclypeus and abdominal terga brown; crown spots, mesonotal triangles, and mesosternum dark brown; forewing with red longitudinal streak in clavus and another along vein Cu in basal half. Pygofer (Fig. 3U) with dorsal appendage arising near apex, very slender, straight, not reaching distal margin; ventral appendage short, relatively broad, extended dorsomesad then curved dorsolaterad; lobe between appendages narrowly rounded, well sclerotized except near margin. Aedeagus (Figs. 3V, W) with shaft narrowly J-shaped, apex compressed, falcate in lateral view; distal processes arising distad of gonopore, sinuately curved posteroventrad, crossing each other medially near apex. Material examined. Holotype male, MEXICO: Veracruz, rt. 180, km#31, 17 km NW Alvarado, 0m, 18°50'N, 95°58'W, 28 October 2001 (C.H. Dietrich, sweep/vac, 01-036-01) [INHS]. Notes. The type series was collected by vacuuming and sweeping low-growing sand dune vegetation along the Gulf Coast of Veracruz, Mexico. The male genitalia of this species resemble those of N. balli Beamer, but the dorsal pygofer appendage is much more slender and elongate, the ventral appendage is longer, and the aedeagal shaft is much longer and nearly straight through most of its length. The coloration of the new species is also distinctive. The forewing of N. veracruzensis has reddish streaks only along vein Cu and in the clavus; N. balli has more extensive areas of reddish pigment covering nearly the entire basal half of the wing.

description: We examine the phase structure of pure Regge gravity in four dimensions and compare our Monte Carlo results with $Z_2$-link Regge-theory as well as with another formulation of lattice gravity derived from group theoretical considerations. Within all three models we find an extension of the well-defined phase to negative gravitational coupling and a new phase transition. In contrast to the well-known transition at positive coupling there is evidence for a continuous phase transition which might be essential for a possible continuum limit.

description: Microstructural deformation of elastic lamellae plays important roles in maintaining arterial tissue homeostasis and regulating vascular smooth muscle cell fate. Our study unravels the underlying microstructural origin that enables elastic lamellar layers to evenly distribute the stresses through the arterial wall caused by intraluminal distending pressure, a fundamental requirement for tissue and cellular function. A new experimental approach was developed to quantify the spatial organization and unfolding of elastic lamellar layers under pressurization in mouse carotid arteries by coupling physiological extension–inflation and multiphoton imaging. Tissue-level circumferential stretch was obtained from analysis of the deformation of a thick-walled cylinder. Our results show that the unfolding and extension of lamellar layers contribute simultaneously to tissue-level deformation. The inner lamellar layers are wavier and unfold more than the outer layers. This waviness gradient compensates the larger tissue circumferential stretch experienced at the inner surface, thus equalizing lamellar layer extension through the arterial wall. Discoveries from this study reveal the importance of structural inhomogeneity in maintaining tissue homeostasis through the arterial wall, and may have profound implications on vascular remodelling in aging and diseases, as well as in tissue engineering of functional blood vessels.
The Distribution of Nearby Stars in Velocity Space Inferred from Hipparcos Data

description: (abridged) The velocity distribution f(v) of nearby stars is estimated, via a maximum- likelihood algorithm, from the positions and tangential velocities of a kinematically unbiased sample of 14369 stars observed by the HIPPARCOS satellite. f(v) shows rich structure in the radial and azimuthal motions, v_R and v_phi, but not in the vertical velocity, v_z: there are four prominent and many smaller maxima, many of which correspond to well known moving groups. While samples of early-type stars are dominated by these maxima, also up to 25% of red main-sequence stars are associated with them. These moving groups are responsible for the vertex deviation measured even for samples of late-type stars; they appear more frequently for ever redder samples; and as a whole they follow an asymmetric-drift relation, in the sense that those only present in red samples predominantly have large |v_R| and lag in v_phi w.r.t. the local standard of rest (LSR). The question arise, how these old moving groups got on their eccentric orbits. A plausible mechanism, known from solar system dynamics, which is able to manage a shift in orbit space involves locking into an orbital resonance. Apart from these moving groups, there is a smooth background distribution, akin to Schwarzschild's ellipsoidal model, with axis ratio of about 1:0.6:0.35 in v_R, v_phi, and v_z. The contours are aligned with the $v_r$ direction, but not w.r.t. the v_phi and v_z axes: the mean v_z increases for stars rotating faster than the LSR. This effect can be explained by the stellar warp of the Galactic disk. If this explanation is correct, the warp's inner edge must not be within the solar circle, while its pattern rotates with frequency of about 13 km/s/kpc or more retrograde w.r.t. the stellar orbits.

Assisting search and rescue through visual Attention
Creators: name: Mardell, James
Publisher: name: Imperial College London

description: With the ubiquity of visual data being recorded, we now have the ability to view vast amounts of visual imagery. However, searching through imagery for an indeterminate target in tasks such as security baggage inspection, medical scan screening and Wilderness Search and Rescue (WiSAR), remains problematic for most people and cannot be automated. If the imagery was presented to account for the way in which humans cognitively process such visuals, then the success of these tasks might be improved. This thesis proposes and evaluates a series of presentation methods to manipulate imagery to seek this improvement. A series of user experience studies were conducted. Given the task of searching for inconspicuous 'lost' human beings in a WiSAR scenario, subjects observed multiple sequences of aerial photography embodied in six specially designed presentations. These presentations were designed following an analysis of existing visual attention literature. The first study to evaluate these methods compared the standard live (i.e. scrolling) view of the terrain to a static representation. This static portrayal of aerial search yielded an improved success rate for target location. The second method adapted the static representation, by segmenting the image into smaller tiles that were displayed for correspondingly shorter durations, while the third method enlarged the segmented tiles to fill the display. With increased segmentation, the ability for subjects to locate targets was broadly unaffected. The fourth study investigated two methods that use eye-tracking equipment to dynamically enhance the display. Contained within this thesis are the findings from these four studies, which include the analysis of each subject's performance, opinions and eye-movement behaviour. The inspiration for each presentation method was the development of a proposed model for visual search. Ultimately, the static method is revealed as the most effective for the chosen scenario of WiSAR.
