Investigation of the Factors Affecting the Population Dynamics of Captive Partula Snails
Creators: name: Gouveia, Ana Rita Peres Cardoso
Publisher: name: Imperial College London
Year: 2011

description: Partula snails, also known as Polynesian tree snails, were first recorded scientifically from Captain Cook's voyage 236 years ago. They are small gastropod molluscs which belong to the order Stylommatophora. Their distribution is focused in the Pacific region where the majority of the species are island endemics. Half the species are found in the Society Islands of French Polynesia where most research has been carried out. Wild populations were almost annihilated following the introduction of a predatory snail, Euglandina rosea, to control the introduced giant African land snail (Lissachatina fulica) which had become an agricultural pest affecting the local economy. In 1987 the Partula Propagation Group (PPG) initiated a worldwide captive breeding programme for Partula snails in an attempt to save them from extinction. In captivity, though, episodes of high mortality have led to the extinction of some species. The causes of these declines are as yet uncertain. This study aimed to investigate the factors that have affected the survival of 15 species (including two subspecies) of Partula snails in captivity. In summary, the results indicate that both environmental factors (temperature, relative humidity and light) and diet (calcium concentration and dog and cat vitamins in the diet) significantly affect the population dynamics of Partula snails. Both excess light and unstable temperatures and humidity had detrimental impacts on the survival and reproductive success of the species. Additionaly, the low concentration of calcium and the addition of dog and cat vitamins in the diet are also significantly detrimental on the survival and reproductive success of Partula gibba. These studies are highly significant because the biology and requirements of Partula snails are poorly understood, and this can jeopardise a successful captive breeding programme and future reintroductions into their natural environment. It is imperative that the factors that have affected the survival rates of snails in captivity for the last 25 years are fully understood. Partula snails face an uncertain future, with the mass mortality episodes observed during the years several species were lost. It is hoped that these findings stimulate further research in this area and can be applied to other species in similar circumstances.

A novel hybrid score level and decision level fusion scheme for cancelable multi-biometric verification
Creators: name: Dwivedi, Rudresh

Publisher: name: arXiv
Year: 2018
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: In spite of the benefits of biometric-based authentication systems, there are few concerns raised because of the sensitivity of biometric data to outliers, low performance caused due to intra-class variations and privacy invasion caused by information leakage. To address these issues, we propose a hybrid fusion framework where only the protected modalities are combined to fulfill the requirement of secrecy and performance improvement. This paper presents a method to integrate cancelable modalities utilizing mean-closure weighting (MCW) score level and Dempster-Shafer (DS) theory based decision level fusion for iris and fingerprint to mitigate the limitations in the individual score or decision fusion mechanisms. The proposed hybrid fusion scheme incorporates the similarity scores from different matchers corresponding to each protected modality. The individual scores obtained from different matchers for each modality are combined using MCW score fusion method. The MCW technique achieves the optimal weight for each matcher involved in the score computation. Further, DS theory is applied to the induced scores to output the final decision. The rigorous experimental evaluations on three virtual databases indicate that the proposed hybrid fusion framework outperforms over the component level or individual fusion methods (score level and decision level fusion). As a result, we achieve (48%,66%), (72%,86%) and (49%,38%) of performance improvement over unimodal cancelable iris and unimodal cancelable fingerprint verification systems for Virtual_A, Virtual_B and Virtual_C databases, respectively. Also, the proposed method is robust enough to the variability of scores and outliers satisfying the requirement of secure authentication.
Phosphatidylinositol transfer proteins : does the topology and the stored curvature elastic stress of lipid bilayers regulate membrane-association and lipid abstraction?
Creators: name: Goehring, Natalia
Publisher: name: Imperial College London
Year: 2011

description: Lipids in a bilayer determine the stresses and the topology of the membrane they form. An understanding of the link between lipid composition and biomechanical parameters such as the spontaneous curvature and bending rigidity is key to elucidate the mechanisms behind protein‐membrane interactions. Despite their relatively low abundance in‐vivo, one of the most important class of lipids involved in signalling cascades in cells are the phosphatidylinositols (PIs) lipids. Experimental studies of the effect of phosphatidylinositol lipids upon model and cellular membrane systems remain in their infancy and have not matched the pace of discovery with respect to their role in regulating key cellular processes. Synthesised at the endoplasmic reticulum, one route for the distribution of the PIs to other organelle membranes is via translocation by the phosphatidylinositol transfer proteins (PITP). In order to study the link between membrane composition and PITP function, these proteins have been assayed for their interaction and binding with model membranes containing differing amounts of PI. Corresponding studies of the phase behaviour of these systems have been conducted using Small Angle X‐ray scattering specifically investigating the influence PI has in a bilayer membrane formed by dioleoylphosphatidylcholine, as well as in an inverted hexagonal phase formed by dioleoyl‐phosphatidylethanolamine. Additionally, a novel platform based upon a BODIPY fluorescent probe is presented, which is able to sense the stored stresses within lipid bilayers, and whose measurements are correlated these with the make‐up of membranes.

In particular we apply this analysis to a wide class of supergravities to argue against the existence of smooth domain walls interpolating between supersymmetric vacua. We find that if the superpotential changes sign then any Goldstino modes will diverge.

On Representations of Conformal Field Theories and the Construction of Orbifolds
Creators: name: Montague, P. S.
Publisher: name: arXiv
Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider representations of meromorphic bosonic chiral conformal field theories, and demonstrate that such a representation is completely specified by a state within the theory. The necessary and sufficient conditions upon this state are derived, and, because of their form, we show that we may extend the representation to a representation of a suitable larger conformal field theory. In particular, we apply this procedure to the lattice (FKS) conformal field theories, and deduce that Dong's proof of the uniqueness of the twisted representation for the reflection-twisted projection of the Leech lattice conformal field theory generalises to an arbitrary even (self-dual) lattice. As a consequence, we see that the reflection-twisted lattice theories of Dolan et al are truly self-dual, extending the analogies with the theories of lattices and codes which were being pursued. Some comments are also made on the general concept of the definition of an orbifold of a conformal field theory in relation to this point of view.

Scrutinizing coupled vector dark energy in light of data

description: Since current challenges faced by $Λ$CDM might be hinting at new unravelled physics, here we investigate a plausible cosmological model where a vector field acts as source of dark energy. In particular, we examine whether an energy-momentum exchange between dark energy and dark matter could provide an explanation for current discrepancies in cosmological parameters. We carefully work out equations governing background and linear order perturbations and implement them in a Boltzmann code. We found that a negative coupling makes the dark energy equation of state less negative and closer to a cosmological constant during the matter dominated epoch than an uncoupled vector dark energy model. While the effect of the coupling is hardly noticeable through its effect on matter density perturbations, matter velocity perturbations and gravitational potentials are enhanced at late-times when dark energy dominates. Therefore, data of redshift space distortions help to narrow down these kinds of couplings in the dark sector. We computed cosmological constraints and found common parameters also present in $Λ$CDM are in good agreement with the Planck Collaboration baseline result. Our best fit for a negatively coupled vector field predicts a higher growth rate of matter perturbations at low redshift, thus exacerbating the disagreement with redshift space distortions data. While a positively coupled vector field can lead to power suppression of $P_{\rm{m}}(k,z=0)$ on small scales as well as a lower growth rate of matter perturbations than the standard model, it might compromise the goodness of fit to the CMB angular power spectrum on small scales. We conclude that our negatively coupled vector dark energy model does not solve current tensions (i.e., $H_0$ and $σ_8$). (abridged)

Diffraction effects in mechanically chopped laser pulses

description: A mechanical beam chopper consists of a rotating disc of regularly spaced wide slits which allow light to pass through them. A continuous light beam, after passing through the rotating disc, is switched-on and switched-off periodically, and a series of optical pulses are produced. The intensity of each pulse is expected to rise and fall smoothly with time. However, a careful study has revealed that the edges of mechanically chopped laser light pulses consist of periodic intensity undulations which can be detected with a photo detector. It has been shown in this paper that the intensity undulations in mechanically chopped laser pulses are produced by diffraction of light from the rotating disc and a detailed explanation of the intensity undulations is given. The experiment provides an efficient method to capture a one dimensional diffraction profile of light from a straight sharp-edge in the time domain. In addition, the experiment accurately measured wavelengths of three different laser beams from the undulations in mechanically chopped laser light pulses.
DP-Colorings of Hypergraphs

description: Classical problems in hypergraph coloring theory are to estimate the minimum number of edges, $m_2(r)$ (respectively, $m^\ast_2(r)$), in a non-$2$-colorable $r$-uniform (respectively, $r$-uniform and simple) hypergraph. The best currently known bounds are \[c \cdot \sqrt{r/\log r} \cdot 2^r \,\leqslant\, m_2(r) \,\leqslant\, C \cdot r^2 \cdot 2^r \qquad \text{and} \qquad c' \cdot r^{-\varepsilon} \cdot 4^r \,\leqslant\, m_2^\ast(r) \,\leqslant\, C' \cdot r^4 \cdot 4^r,\] for any fixed $\varepsilon > 0$ and some $c$, $c'$, $C$, $C' > 0$ (where $c'$ may depend on $\varepsilon$). In this paper we consider the same problems in the context of DP-coloring (also known as correspondence coloring), which is a generalization of list coloring introduced by Dvořák and Postle and related to local conflict coloring studied independently by Fraigniaud, Heinrich, and Kosowski. Let $\tilde{m}_2(r)$ (respectively, $\tilde{m}^\ast_2(r)$) denote the minimum number of edges in a non-$2$-DP-colorable $r$-uniform (respectively, $r$-uniform and simple) hypergraph. By definition, $\tilde{m}_2(r) \leqslant m_2(r)$ and $\tilde{m}^\ast_2(r)\leqslant m^\ast_2(r)$. While the proof of the bound $m^\ast_2(r) = Ω( r^{-3} 4^r)$ due to Erdős and Lovász also works for $\tilde{m}^\ast_2(r)$, we show that the trivial lower bound $\tilde{m}_2(r) \geqslant 2^{r-1}$ is asymptotically tight, i.e., $\tilde{m}_2(r) \leqslant (1 + o(1))2^{r-1}$. On the other hand, when $r \geqslant 2$ is even, we prove that the lower bound $\tilde{m}_2(r) \geqslant 2^{r-1}$ is not sharp, i.e., $\tilde{m}_2(r) \geqslant 2^{r-1}+1$. Whether this result holds for any odd values of $r$ remains an open problem. Nevertheless, we conjecture that the difference $\tilde{m}_2(r) - 2^{r-1}$ can be arbitrarily large.

description: A good group reputation often facilitates more efficient synergistic teamwork in production activities. Here we translate this simple motivation into a reputation-based synergy and discounting mechanism in the public goods game. Specifically, the reputation type of a group, either good or bad determined by a reputation threshold, modifies the nonlinear payoff structure described by a unified reputation impact factor. Results show that this reputation-based incentive mechanism could effectively promote cooperation compared with linear payoffs, despite the coexistence of synergy and discounting effects. Notably, the complicated interactions between reputation impact and reputation threshold result in a sharp phase transition from full cooperation to full defection. We also find that the presence of a few discounting groups could increase the average payoffs of cooperators, leading to an interesting phenomenon that when the reputation threshold is raised, the gap between the average payoffs of cooperations and defectors increases while the overall payoff decreases. Our work provides important insights into facilitating cooperation in social groups.

Tools for single cell proteomics
Creators: name: Salehi-Reyhani, Ali
Publisher: name: Imperial College London
Year: 2011

description: Despite recent advances that offer control of single cells, in terms of manipulation and sorting and the ability to measure gene expression, the need to measure protein copy number remains unmet. Measuring protein copy number in single cells and related quantities such as levels of phosphorylation and protein-protein interaction is the basis of single cell proteomics. A technology platform to undertake the analysis of protein copy number from single cells has been developed. The approach described is ‘all-optical’ whereby single cells are manipulated into separate analysis chambers using an optical trap; single cells are lysed by mechanical shearing caused by laser-induced microcavitation; and the protein released from a single cell is measured by total internal reflection microscopy as it is bound to micro-printed antibody spots within the device. The platform was tested using GFP transfected cells and the relative precision of the measurement method was determined to be 88%. Single cell measurements were also made on a breast cancer cell line to measure the relative levels of unlabelled human tumour suppressor protein p53 using a chip incorporating an antibody sandwich assay format. This demonstrates the ability count protein copy number from single cells in a manner which could be applied in principle to any set of proteins and for any cell type without the need for genetic engineering. Metabolism can undergo alteration in diseases such as cancer and heart failure and also as cells differentiate during development. In order to assess how it may inform a proteomic measurement, multidimensional two-photon fluorescence metabolic imaging is conducted on a cultured cancer cell line, primary adult rat cardiomyocytes and human embryonic stem cells. By measuring the parameters of fluorescence such as intensity and lifetime of the autofluorescent metabolic co-factors NADH and FAD, it was found to be possible to contrast cells under various conditions and metabolic stimuli. In particular, human embryonic stem cells were able to be contrasted at 3 stages of development as they underwent differentiation into embryonic stem cell derived cardiomyocytes. Metabolic imaging provides a non-destructive method to monitor cellular metabolic activity with high resolution. This is complimentary to the single cell proteomic platform and the convergence of both techniques holds promise in future investigations into how metabolism influences cell function and the proteome in development and disease.

For consistency, GPS data is used to select dynamically the best PIM parameters, in a 3DVAR fashion. We demonstrate the ingestion of GPS (IGS and GPS/MET) data into a parameterized ionospheric model, used to select the set of parameters that minimize a suitable cost functional. The resulting PIM-fitted model is compared to direct 3D voxel tomography. We demonstrate the value of this method analyzing IGS and GPS/MET GPS data, and present our results in terms of a 4D model of the ionospheric electronic density.

description: Core-collapse supernovae are sources of powerful gravitational waves (GWs). We assess the possibility of extracting information about the equation of state (EOS) of high density matter from the GW signal. We use the bounce and early post-bounce signals of rapidly rotating supernovae. A large set of GW signals is generated using general relativistic hydrodynamics simulations for various EOS models. The uncertainty in the electron capture rate is parametrized by generating signals for six different models. To classify EOSs based on the GW data, we train a convolutional neural network (CNN) model. Even with the uncertainty in the electron capture rates, we find that the CNN models can classify the EOSs with an average accuracy of about 87 percent for a set of four distinct EOS models.

description: Following on from recent work describing the representation content of a meromorphic bosonic conformal field theory in terms of a certain state inside the theory corresponding to a fixed state in the representation, and using work of Zhu on a correspondence between the representations of the conformal field theory and representations of a particular associative algebra constructed from it, we construct a general solution for the state defining the representation and identify the further restrictions on it necessary for it to correspond to a ground state in the representation space. We then use this general theory to analyze the representations of the Heisenberg algebra and its $Z_2$-projection. The conjectured uniqueness of the twisted representation is shown explicitly, and we extend our considerations to the reflection-twisted FKS construction of a conformal field theory from a lattice.

description: We investigate propagation of gravitational waves in the most general teleparallel gravity model with second order field equations around the Minkowski background. We argue that in this case the most general Lagrangian at the first order of perturbations is given by the linear combination of quadratic invariants and hence coincides with the well-known new general relativity model. We derive the linearized field equations and analyze them using the principal polynomial and the Newman-Penrose formalism. We demonstrate that all gravitational wave modes propagate at the speed of light and there are up to six possible polarizations. We show that two tensorial modes of general relativity are always present and the number of extra polarizations depends on the free parameters of the new general relativity model.

The introduction of a phase variable enables an effective representation of grain geometry and facilitates the application of physical laws, such as chemo-mechanical couplings, for modeling shape changes. These physical laws are solved numerically using the finite element method coupled in a staggered scheme to the discrete element model. The efficacy of the proposed Phase-Field Discrete Element Model (PFDEM) is demonstrated through its ability to accurately capture the real grain shape in a material subjected to dissolution only and compute the stress evolution. It is then applied to model the phenomenon of pressure solution involving dissolution and precipitation in granular materials at the microscale and enables to reproduce the creep response observed experimentally. This framework contributes to the enhanced understanding and simulation of complex behaviors in granular materials and sedimentary rocks for many geological processes like diagenesis or earthquake nucleation.

Ab initio Studies of Aluminium Halides
Creators: name: Bailey, Christine Lynn
Publisher: name: Imperial College London
Year: 2009

description: The catalytic fluorination of hydrocarbons facilitates the large-scale production of chlorofluorocarbons for a wide range of applications including aerosol propellants, refrigerants and solvents. Lewis acid catalysts, such as Swarts catalysts based on antimony pentafluoride, are commonly used. Recently, a sol-gel based synthesis method has been developed which yields very high surface area aluminium fluoride (HS-AlF3) that has a Lewis acidity comparable to that of the Swarts catalysts. This makes HS-AlF3 a promising candidate for use in several Lewis acid catalysed reactions. Despite the importance of the surface in the catalytic process little is known about the detailed atomic scale structure of AlF3 surfaces. Surface thermodynamics calculations, based on hybrid-exchange density functional theory, are employed to predict the composition and structure of AlF3 surfaces. The surfaces of AlF3 expose under coordinated Al ions that are potential Lewis acid sites. Under standard atmospheric conditions the AlF3 surfaces are shown to adsorb water above the under coordinated Al ions. Theoretical characterisation of the under coordinated Al ions shows that the most reactive type of site is not exposed on crystalline α-AlF3 samples, however, it is predicted to occur in small quantities on β crystallites. It is speculated that such sites occur in higher quantities on the high surface area materials. This result may explain the different reactivity of α-, β- and HS-AlF3. Our detailed understanding of AlF3 surfaces allows us to propose a reaction centre and mechanism for the dismutation of CCl2F2 on β-AlF3. Aluminium chloride is extensively used as a catalyst in Friedal-Crafts reactions. It is therefore, commonly assumed that pure crystalline AlCl3 is strongly Lewis acidic. Ab initio surface thermodynamics calculations are used to study the surfaces of crystalline AlCl3 and show that it is chemically inert.
Critical collapse of ultra-relativistic fluids: damping or growth of aspherical deformations

description: We perform fully nonlinear numerical simulations to study aspherical deformations of the critical self-similar solution in the gravitational collapse of ultra-relativistic fluids. Adopting a perturbative calculation, Gundlach predicted that these perturbations behave like damped or growing oscillations, with the frequency and damping (or growth) rates depending on the equation of state. We consider a number of different equations of state and degrees of asphericity and find very good agreement with the findings of Gundlach for polar $\ell = 2$ modes. For sufficiently soft equations of state, the modes are damped, meaning that, in the limit of perfect fine-tuning, the spherically symmetric critical solution is recovered. We find that the degree of asphericity has at most a small effect on the frequency and damping parameter, or on the critical exponents in the power-law scalings. Our findings also confirm, for the first time, Gundlach's prediction that the $\ell = 2$ modes become unstable for sufficiently stiff equations of state. In this regime the spherically symmetric self-similar solution can no longer be recovered by fine-tuning to the black-hole threshold, and one can no longer expect power-law scaling to hold to arbitrarily small scales.

Intestinal and urinary schistosomiasis dynamics in sub-Saharan Africa
Creators: name: Gouvras, Anouk N
Publisher: name: Imperial College London
Year: 2010

description: Schistosomiasis is a chronic infection by a digean trematode of the genus Schistosoma. More than 207 million people are infected with this parasite, of which 120 million are symptomatic. There are two main species infecting humans in sub-Saharan Africa: Schistosoma haematobium and S. mansoni, both occur in areas with similar socio-economic and environmental conditions and often have matching distribution patterns. The principle aims of the research presented in this thesis were to further our understanding of schistosome population genetics, associated human host morbidity and chemotherapeutic treatment of schistosomes in relation to mixed species infections. Structured sampling of parasites and/or host traits from school-aged children at baseline and post Mass Drug Administration (MDA) in Niger and Kenya were performed. The results presented provided evidence for S. haematobium - S. mansoni interactions and their impact on the human host and on the parasite population. In Kenya coinfections had lower S. haematobium related morbidity relative to single S. haematobium infections pre and post MDA. Additionally parasite infra-populations from coinfected children had higher genetic diversity levels compared to single infected children in mixed infection foci. In Niger, an impact of MDA on the population genetics of S. mansoni was detected in one mixed infection village, characterised as a noticeable bottleneck effect, but not in the other. There was no apparent impact of MDA on the population genetics of S. haematobium. Conversely, in Kenya, a significant impact of MDA on both species was detected, with a bottleneck effect occurring on the S. haematobium population and conversely, an increase in genetic diversity in the S. mansoni population. The results of this thesis are discussed in terms of their implications on schistosome epidemiology and evolution, and in relation to the control of schistosomiasis in sub-Saharan Africa.
