description: Prior social contagion models consider the spread of either one contagion at a time on interdependent networks or multiple contagions on single layer networks or under assumptions of competition. We propose a new threshold model for the diffusion of multiple contagions. Individuals are placed on a multiplex network with a periodic lattice and a random-regular-graph layer. On these population structures, we study the interface between two key aspects of the diffusion process: the level of synergy between two contagions, and the rate at which individuals become dormant after adoption. Dormancy is defined as a looser form of immunity that models the ability to spread without resistance. Monte Carlo simulations reveal lower synergy makes contagions more susceptible to percolation, especially those that diffuse on lattices. Faster diffusion of one contagion with dormancy probabilistically blocks the diffusion of the other, in a way similar to ring vaccination. We show that within a band of synergy, contagions on the lattices undergo bimodal or trimodal branching if they are the slower diffusing contagion.

For smooth manifolds with spin structure, this could explain why the phase factor $Ω(x)$ calculated with a D-brane state x in IIB theory appears in Diaconescu, Moore and Witten's computation of the partition function of IIA string theory.

An investigation into environmental modifiers of grassland response to ozone
Creators: name: Khalid, Sofia
Publisher: name: Imperial College London
Year: 2011

description: The thesis concerns the role of nitrogen and drought in modifying the responses of grassland plant species towards tropospheric ozone. The first part focuses on nitrogen with a pilot study conducted in green-house environment with closed chambers and four plant species from mesotrophic grasslands growing singly in pots. Nitrogen (up to 50 Kg/ha) and ozone (up to 90 ppb) showed that high nitrogen ameliorated detrimental ozone effects on visible injury in Cirsium arvense, Centaurea nigra and Trifolium pratense. Low nitrogen (0 Kg/ha) on the other hand, counterbalanced ozone effects by showing greater number of leaves as well as greater above ground, below ground and total biomass in Holcus lanatus. An expansion of the ozone x nitrogen interactions, exploring combined effects on photosynthesis and stomatal conductance, was carried out in open top chambers facility at Silwood Park (Ascot, UK), using four air treatments (Filtered Air, 40, 70 and 100 ppb ozone). Species representative of calcifugous grasslands, grown both as mixed and single species were used. The results indicted that ozone-induced decreases in stomatal conductance were greater in high-nitrogen-treated Trifolium repens grown as a single species. Similarly greater ozone-induced decreases were found for photosynthesis rates of high nitrogen treated Trifolium repens and Rumex acetosella grown as single and mixed species. The second part of the research evaluates the ecological impacts of rising tropospheric ozone levels and drought on grassland mesocosms characteristic of Silwood Park. The experiment was conducted in the open top chambers with rain exclusion roofs. Ozone concentrations used were 0 (Filtered Air), 30, 60 & 90 ppb. The results showed species level differences in response to both ozone and drought. Generally greater ozone effects were observed on well-watered plants and this could be explained through greater stomatal conductance when compared to droughted plants, leading to greater ozone flux. At community level, above ground biomass responses showed an increased dominance of grasses compared to forbs in high-ozone, well-watered treatments.

Role and functional consequences of PU.1 transcriptional factor loss and mutations in a mouse model of radiation-induced acute myeloid leukaemia
Creators: name: Olme, Carl-Henrik Axel
Publisher: name: Imperial College London
Year: 2011

description: In a mouse model of radiation-induced acute myeloid leukaemia (rAML), the CBA/H strain, copy loss of Sfpi1 is found in up to 90 % of cases. The gene codes for the transcription factor PU.1, an important regulator of haematopoiesis, which acts as a tumour suppressor. Point mutations specifically in the DNA sequence encoding the binding domain of the protein are found at a high frequency, suggesting that the transcription factor has a reduced function in leukaemic blasts. Transgenic CBA/H mice expressing green fluorescent protein (GFP) under the control of the Sfpi1 promoter allowed the use of flow cytometry to, for the first time, study copy loss of Sfpi1 in cases of rAML by analysing the expression levels of GFP. Analysis of mRNA levels of Sfpi1 showed there probably is a different mechanism for leukaemogenesis in cases with point mutations in the sequence encoding the DNA binding domain compared to cases with a wild type Sfpi1, the former potentially through lack of function in the transcription factor PU.1 and the latter through suppression of Sfpi1 gene expression. Fluorescent activated cell sorting was used to isolate immature bone marrow cells (BMC) containing Sfpi1 deletions from previously irradiated mice. The isolated cells were transplanted into myeloablated hosts with some success, although this new approach to study radiation-induced leukaemogenesis needs refinement. A population of immature BMCs was found to be less radiosensitive in the CBA/H strain compared to the C57BL/6 strain, which is not susceptible to rAML. This gave an indication of where the target cell population for the initial leukaemic events may occur. The work in this thesis presents novel ways of studying early events in rAML induction in the CBA/H mouse and gives new insights into the mechanisms of leukaemogenesis in the model.

description: We report the MAXI observation of the gravitational-wave (GW) event GW170817 and the electromagnetic counterpart of GW170817. GW170817 is a binary neutron star coalescence candidate detected by the Advanced LIGO and Advanced Virgo detectors, and it is the first event for which the optical counterpart has been discovered. In the MAXI observation, the Gas Slit Camera (GSC) covered approximately 62% of the sky region of the GW event within 90% probability during the first 92 min of orbit after the trigger. No significant X-ray transient was detected in the error region, and the upper limit of the average flux with a significance of 3 $σ$ in the 2--10 keV band was 53/26 mCrab (one-orbit observation/one-day observation). In the optical counterpart of GW170817, the observational window of GSC at the position started at 20 s after the GW trigger, but the high voltage of GSC was unfortunately off at the time because the ISS was entering a high-particle-background region. The first observation of the position by GSC was eventually performed at 16797 sec (4.6 hours) since the GW trigger, yielding the 3 $σ$ upper limit of 8.60$\times$10$^{-9}$ erg cm$^{-2}$ s$^{-1}$ in the 2--10 keV band, though it was the earliest X-ray observation of the counterpart.

Molecular and genetic mechanisms of myocardial insulin resistance in humans and mice
Creators: name: Kleinert, Christina
Publisher: name: Imperial College London
Year: 2011

description: Patients with type 2 diabetes mellitus have a greatly increased risk of coronary artery disease and heart failure due to a number of factors such as insulin resistance, hyperglycaemia, arterial hypertension, and obesity. To study the changes seen in hearts of diabetic patients the aim of this project was to generate a clinically relevant diet-induced obese mouse model which could mimic these changes. Male C57BL/6 mice were fed a 45% high fat diet for 8, 11, and 14 weeks. Metabolic and histological changes in animals that responded to the high fat diet (diet-induced obese, DIO) were investigated and the most appropriate feeding period was determined for further studies. DIO animals showed significantly increased body weight gain, elevated fasting serum insulin levels and over time animals developed impaired glucose tolerance. Histological analysis of DIO hearts after 14 weeks of high fat diet showed significantly increased interstitial fibrosis and after all three time points a previously unrecognised coronary microvascular remodelling was observed in DIO mice. Molecular mechanisms involved in insulin resistance and coronary microvascular remodelling were investigated in DIO mice after 11 weeks of high fat diet. Animals showed alterations in coronary flow, endothelial dysfunction and myocardial gene expression analysis revealed differentially expressed genes involved in lipid and carbohydrate metabolism. Validation experiments showed that one of these genes, regulator of G-protein signalling (RGS2), had a significant reduction at both RNA and protein level in total heart lysates. Additionally, RGS2 expression in vascular smooth muscle cells of small vessels in the heart was significantly reduced in DIO mice. After a shift from high fat to a normal rodent chow a reversal of microvascular remodelling as well as a return of RGS2 expression levels back to baseline were observed. In conclusion, this diet-induced mouse model shows features of cardiomyopathy and coronary microvascular remodelling which is closer to the phenotype seen in patients with arterial hypertension or hypertrophic cardiomyopathy compared to other mouse or rat models.

description: Instanton and seven-brane solutions of type IIB supergravity carrying charges in the Ramond-Ramond sector are constructed. The singular seven-brane has a quantized \RR \ \lq magnetic' charge whereas its dual is the instanton, which is non-singular in the string frame and has an associated {\it global} \lq electric' charge. The product of these charges is constrained by a Dirac quantization condition. The instanton has the form of a space-time wormhole in the string frame, and is responsible for the non-conservation of the Noether current.

Magnetic and spin evolution of neutron stars in close binaries

description: The evolution of neutron stars in close binary systems with a low-mass companion is considered assuming the magnetic field to be confined within the solid crust. We adopt the standard scenario of the evolution in a close binary system in accordance with which the neutron star passes throughout four evolutionary phases ("isolated pulsar" -- "propeller" -- accretion from the wind of a companion -- accretion due to Roche-lobe overflow). Calculations have been performed for a great variety of parameters characterizing the properties both of the neutron star and low-mass companion. We find that neutron stars with more or less standard magnetic field and spin period being processed in low-mass binaries can evolve to low-field rapidly rotating pulsars. Even if the main-sequence life of a companion is as long as $10^{10}$ yr, the neutron star can maintain a relatively strong magnetic field to the end of the accretion phase. The considered model can well account for the origin of millisecond pulsars.

The differential freeze out scenario of strange hadron $K^{0}_{s}$ assumed while analyzing the data using a Tsallis distribution which is modified to include transverse flow. The $p_{T}$ distributions of strange hadron in different systems are characterized in terms of the parameters namely, Tsallis temperature ($T$), power ($n$) and average transverse flow velocity ($β$).

Metallic Nanopores for Single Molecule Biosensing
Creators: name: Ayub, Mariam
Publisher: name: Imperial College London
Year: 2011

description: This thesis describes a novel approach to the fabrication and characterisation of metallic nanopores and their application for the detection of single DNA molecules. Metallic nanopores with apparent diameters below 20 nm are produced using electrochemical deposition and real-time ionic current feedback. Beginning with large nanopores (diameter 100-200 nm) milled into gold silicon nitride membranes using a focused ion beam, platinum metal is electrodeposited onto the gold surface, thus reducing the effective pore diameter. By simultaneously observing the ion current feedback, the shrinking of the nanopore can be monitored and terminated at any pre-defined value of the pore conductance in a precisely controlled and reproducible way. The ion transport properties of the metallic nanopore system are investigated by characterising the pore conductance at varying potentials across the nanopore and concentrations of electrolyte. The results are compared to conventional bare silicon nitride nanopore systems. Chemical modification at the nanopore surface is also studied using thiolisation to reduce the capacitive charging effects observed with metallic nanopores. Further to this, impedance measurements are carried out to study the resistive behaviour exhibited in these systems. An equivalent circuit model is proposed to validate the results obtained from the experimental studies. To evaluate the suitability of these nanopores for applications in single-molecule biosensing, translocation experiments using λ-DNA are performed. DNA molecules are electrokinetically driven through the nanopore under an applied electric field, hence as the DNA translocates through the pore, current blockade events are detected. Each event is the result of a single molecular interaction of DNA with the nanopore and is characterised by its dwell time and amplitude. Characterisation studies and noise analysis towards the applicability of metallic nanopores as single molecule detectors are also studied and compared to current bare silicon nitride pore systems.

The MeerChoirs View of HI in Galaxy Groups
Creators: name: Mogotsi, Moses
Publisher: name: Zenodo
Year: 2024

description: MeerChoirs is a HI survey of nearby (23-151 Mpc) galaxy groups selected from SINGG.  The groups were observed in the H-alpha, R-band and UV, and they cover a wide range of compactness, number of members, HI-richness and group evolution.  Therefore, their constituent galaxies are in a wide range of environments.  MeerKAT provides an unprecedented combination of high sensitivity, spatial resolution and wide field of view; this is ideal for resolved observations of large and dwarf galaxies, and the intra-group medium of these groups.  This is highlighted by how the initial results from the survey have identified many HI sources in our groups, and large amounts of gas outside of some of the galaxy discs.  In some cases the intra-group gas is more massive than the magellanic clouds, and we detect many signatures of gas inflows and inflows.  These observations are the best to date of these groups and are key to understanding the flow of baryons and fuelling of star formation in group galaxies.  I will be presenting the results from our work and how MeerKAT is proving to be an excellent instrument for such studies.

description: A new construction of biorthogonal splines for isogeometric mortar methods is proposed. The biorthogonal basis has a local support and, at the same time, optimal approximation properties, which yield optimal results with mortar methods. We first present the univariate construction, which has an inherent crosspoint modification. The multivariate construction is then based on a tensor product for weighted integrals, whereby the important properties are inherited from the univariate case. Numerical results including large deformations confirm the optimality of the newly constructed biorthogonal basis.

In particular, we identify the $S$-duality between noncommutative open string theory and noncommutative Yang-Mills theory in $(3+1)$ dimensions as the exchange of two circles of a torus on which OM-theory is compactified. Also, we briefly discuss $T$-duality between noncommutative open string theories.

Strategies for personal mobility: A study of consumer acceptance of subscription drive-it-yourself car services
Creators: name: Le Vine, Scott
Publisher: name: Imperial College London
Year: 2011

description: This thesis investigates consumer acceptance of subscription drive-it-yourself car services [SDCSs], which are an evolution of car hire that began entering the commercial marketplace in the mid- 1990s. The aim of this research is to develop techniques to forecast how consumer demand for SDCSs may develop. On the basis of research reported in this thesis, it is argued that a person’s [strategic] decision to subscribe to an SDCS can be reasonably considered to have a dependency with their expectation of [tactically] using it to access particular out-of-home personal activities. It is shown that people can also be thought to view subscribing to an SDCS as part of a larger ‘portfolio’ choice of travel options. Traditional analyses of people’s travel choices are insensitive to these two issues. Two datasets, one revealed-choice and the other stated-choice, were designed in order to provide empirical data to test the proposed ‘strategic/tactical’ and ‘portfolio’ analytical form. The revealed-choice dataset made use of web-based data-mining techniques, whilst the stated-choice survey is novel in several respects to address the challenges presented by the SDCS context. The methodological innovations proposed in this research proved successful in forecasting consumer demand for SDCSs in the empirical application, and appear promising for wider use within the transport domain and related research fields.
The Fraction of Stars That Form in Clusters in Different Galaxies

description: We estimate the fraction of stars that form in compact clusters (bound and unbound), Gamma_F, in a diverse sample of eight star-forming galaxies, including two irregulars, two dwarf starbursts, two spirals, and two mergers. The average value for our sample is Gamma_F ~ 24 +/- 9%. We also calculate the fraction of stars in clusters that survive to ages between t1 and t2, denoted by Gamma_S(t1,t2), and find Gamma_S(10,100)=4.6 +/- 2.5% and Gamma_S(100,400)=2.4 +/- 1.1 %, significantly lower than Gamma_F for the same galaxies. We do not find any systematic trends in Gamma_F or Gamma_S with the star formation rate (SFR), the SFR per unit area (Sigma_SFR), or the surface density of molecular gas (Sigma_H2) within the host galaxy. Our results are consistent with those found previously from the CMF/SFR statistic (where CMF is the cluster mass function), and with the quasi-universal model in which clusters in different galaxies form and disrupt in similar ways. Our results, however, contradict many previous claims that the fraction of stars in bound clusters increases strongly with Sigma_SFR and Sigma_H_2. We find that the previously reported trends are largely driven by comparisons that mixed Gamma_F ~ Gamma_S(0,10) and Gamma_S(10,100), where Gamma_S(0,10) was systematically used for galaxies with higher Sigma_SFR and Sigma_H2, and Gamma_S(10,100) for galaxies with lower Sigma_SFR and Sigma_H_2.

description: In this article, we present the charged and neutral current coherent pion production in the neutrino-nucleus interaction in the resonance region using the formalism based on the partially conserved axial current (PCAC) theorem which relates the neutrino-nucleus cross section to the pion-nucleus elastic cross section. The pion nucleus elastic cross section is calculated using the Glauber model approach. We calculate the integrated cross sections for neutrino-carbon, neutrino-iron and neutrino-oxygen scattering. The results of integrated cross-section calculations are compared with the measured data

description: The distance to the centroid of the M31 globular cluster system is determined by fitting theoretical isochrones to the observed red-giant branches of fourteen globular clusters in M31. The mean true distance modulus of the M31 globular clusters is found to be 24.47 +/- 0.07 mag. This is consistent with distance modulii for M31 that have been obtained using other distance indicators.

description: Resembling acute promyelocytic leukemia (APL) is a unique subtype of APL who sharing clinical, morphological, and immunophenotypic features with typical APL, but lacking evidence of PML-RARA fusion gene and usually insensitive to arsenic trioxide (ATO) and all-trans retinoic acid (ATRA). For years, RARA, RARB and RARG rearrangement were found in resembling APL continually. The confirmed partner genes of RARG rearrangement included CPSF6, NUP98, NPM1, PML, and HNRNPC. These patients were a group of resembling APL with rare molecular genetic abnormality and unfavorable prognosis. They usually were resistant to ATO and ATRA but partially sensitive to anthracycline-based chemotherapy. We reported a 25-year-old female patient with a novel fusion gene RARG-HNRNPM (RARG chr12:53606869: –; HNRNPM chr19: 8527413: + based on GRCh37/hg19 Assembly) through RNA-seq as resembling APL. The patient with RARG-HNRNPM was benefited from a combined chemotherapy homoharringtonine, cytarabine, and aclacinomycin (HAA) regimen with no relapse. RARG rearrangement resembling APL are various. The treatment should be switched from ATRA/ATO to AML combined chemotherapy regimen early.

Unbound Young Stellar Systems: Star Formation on the loose

description: [abridged] Unbound young stellar systems, the loose ensembles of physically related young bright stars, trace the typical regions of recent star formation in galaxies. Their morphologies vary from small associations of stars to enormous stellar complexes. Being associated with star-forming regions of various sizes, they trace the regions where stars form at various scales, from compact clusters to whole galactic disks. They have been, thus, the focus of several studies with special interest on their demographics, classification, and structural morphology. Their surveys demonstrate that the clear distinction of these systems into well-defined classes is not straightforward, due to their low densities, asymmetric shapes and variety in structural parameters. Unbound stellar structures follow a hierarchical clustering pattern up to the scale of a whole star-forming galaxy. This structural pattern, which is usually characterized as self-similar or fractal, appears to be identical to that of star-forming giant molecular clouds and interstellar gas, driven mainly by turbulence cascade. In this short review, I make a concise compilation of our understanding of unbound young stellar systems across various environments in the local universe, as it is developed during the last 60 years. I present a factual assessment of the clustering behavior of star formation, as revealed from the assembling pattern of stars across loose stellar structures and its relation to the interstellar medium and the environmental conditions. I also provide a consistent account of the processes that possibly play important role in the formation of unbound stellar systems, compiled from both theoretical and observational investigations on the field.

description: The Batalin-Fradkin-Tyutin (BFT) scheme, which is an improved version of Dirac quantization, is applied to the $CP^1$ model, and the compact form of a nontrivial first-class Hamiltonian is directly obtained by introducing the BFT physical fields. We also derive a BRST-invariant gauge fixed Lagrangian through the standard path-integral procedure. Furthermore, performing collective coordinate quantization we obtain energy spectrum of rigid rotator in the $CP^1$ model. Exploiting the Hopf bundle, we also show that the $CP^1$ model is exactly equivalent to the O(3) nonlinear sigma model at the canonical level.

Surface states in Dirac metals and topological crystalline insulators

description: We reconsider the problem of surface states spectrum in type One Dirac metals. We find that the surface states, despite being gapped, always form branches terminating at Dirac points. Furthermore, we consider evolution of the surface states in the case, when rotational symmetry is broken, and as a result, Dirac points are gapped. We find, that in this case, special role is played by mirror symmetry relative to the plane connecting Dirac points. When it is present, the resulting gapped state is a topological crystalline insulator, which surface spectrum can contain either one or three Dirac points, two of which are protected solely by the mirror symmetry. Thus, the Dirac metal can be viewed as a topological phase transition between two phases with different mirror Chern numbers.

description: The dramatic discovery with the Rossi X-Ray Timing Explorer satellite of remarkably coherent $\sim$300--1200 Hz oscillations in the X-ray brightness of some sixteen neutron stars in low-mass binary systems has spurred theoretical modeling of these oscillations and investigation of their implications for the neutron stars and accretion flows in these systems. High-frequency oscillations are observed both during thermonuclear X-ray bursts and during intervals of accretion-powered emission and appear to be a characteristic feature of disk-accreting neutron stars with weak magnetic fields. In this review we focus on the high-frequency quasi-periodic oscillations (QPOs) seen in the accretion-powered emission. We first summarize the key properties of these kilohertz QPOs and then describe briefly the models that have been proposed to explain them. The existing evidence strongly favors beat-frequency models. We mention several of the difficulties encountered in applying the magnetospheric beat-frequency model to the kilohertz QPOs. The most fully developed and successful model is the sonic-point beat-frequency model. We describe the work on this model in some detail. We then discuss observations that could help to distinguish between models. We conclude by noting some of the ways in which study of the kilohertz QPOs may advance our understanding of dense matter and strong gravitational fields.

description: Simple, low-cost, and fast determination of cysteine and glutathione with high sensitivity is an essential problem to evaluate the physiological processes in living organisms. Artificial nanozymes have provided considerable opportunities in biosensing. In this work, using a graphene-based ternary nanozyme, we present a simple but efficient colorimetric method for the determination of cysteine and glutathione. The nanozyme exhibits excellent and stable catalytic performance toward H2O2 and catalyzes the 3,3′,5,5′-tetramethylbenzidine chromogenic reaction. However, this reaction is significantly suppressed by cysteine and glutathione. Thus, a sensitive colorimetric method is presented based upon this inhibition. Excellent performance with low detection limits, good selectivity, and rapid analysis suggests potential bioanalytical applications for the determination of cysteine and glutathione.

description: Topological defects play a key role in a variety of physical systems, ranging from high-energy to solid state physics. They yield fascinating emergent phenomena and serve as a bridge between the microspic and macroscopic world. A skyrmion is a unique type of topological defect, showing great promise for applications in the fields of magnetic storage and spintronics. Here, we discover and observe optical skyrmion lattices that can be easily created and controlled, while illustrating their robustness to imperfections. Optical skyrmions are experimentally demonstrated by interfering surface plasmon polaritons and are measured via phase-resolved near-field optical microscopy. This discovery could give rise to new physical phenomena involving skyrmions and exclusive to photonic systems; open up new possibilities for inducing skyrmions in material systems through light-matter interactions; and enable applications in optical information processing, transfer and storage.
The interplay between MYCN and the DNA damage response: modulation of MYCN expression, its interactions with components of the DNA damage response and cellular responses to N-myc following genotoxic stress
Creators: name: Duarte, Alexandra
Publisher: name: Imperial College London
Year: 2012

description: The DNA damage response (DDR) forms a signaling cascade rapidly activated upon exposure to genotoxic stress. The DDR safeguards genomic integrity by halting cell cycle progression to allow repair of damaged DNA or by inducing cell death. Myc proteins are key regulators of cell proliferation that transcriptionally control the cell cycle machinery. Amplification of N-myc in neuroblastomas (MNA-NB) is associated with abrogation of the regulatory mechanisms that normally prevent aberrant cell proliferation and the interplay between N-myc and the DDR was here analysed. Initially, an association between N-myc and the cdk inhibitor p21 was investigated in MNA-NB as a possible mechanism by which p21 is functionally suppressed in these cells. Although an N-myc/p21 interaction was not observed, MNA-NB cells appear to express short N-myc isoforms with the potential to associate with p21. Expression of N-myc rendered Rat-1 cells resistant to the cell cycle block imposed by serum starvation but these cells were not able to bypass a G1 arrest imposed by ectopic p21 suggesting N-myc does not abolish p21 activity through regulation at the protein level. Analysis of the N-myc response to DNA damage in MNA-NB cells revealed that N-myc is downregulated in a proteasome-dependent manner in response to UVC or a UV-mimetic carcinogen, 4NQO. This effect was not reproduced with other agents such as IR which like UVC were found to repress cyclin D1 expression likely indicating that alternative DDR signaling pathways differently regulate N-myc. N-myc was found to interact with the DDB2 subunit of the damaged-DNA binding (DDB) complex, a substrate receptor for the DDB1-Cul4ADDB2 E3 ligase. The DDB complex has been implicated in UV-induced protein ubiquitylation suggesting it may play a role in the N-myc response to UVC radiation. These findings highlight the complexities of the DDR and uncover potentially important mechanisms of cell cycle control through regulation of N-myc.
