description: We present an analytical model to investigate the production of pebbles and their radial transport through a protoplanetary disk (PPD) with magnetically driven winds. While most of the previous analytical studies in this context assume that the radial turbulent coefficient is equal to the vertical dust diffusion coefficient, in the light of the results of recent numerical simulations, we relax this assumption by adopting effective parametrisations of the turbulent coefficients involved in terms of the strength of the magnetic fields driving the wind. Theoretical studies have already pointed out that even in the absence of winds, these coefficients are not necessarily equal, though its consequences regarding pebble production have not been explored. In this paper, we investigate the evolution of the pebble production line, the radial mass flux of the pebbles and their corresponding surface density as a function of the plasma parameter at the disk midplane. Our analysis explicitly demonstrates that the presence of magnetically-driven winds in a PPD leads to considerable reduction of the rate and duration of the pebble delivery. We show that when the wind is strong, the core growth in mass due to the pebble accretion is so slow that it is unlikely that a core could reach a pebble isolation mass during a PPD lifetime. When the mass of a core reaches this critical value, pebble accretion is halted due to core-driven perturbations in the gas. With decreasing wind strength, however, pebble accretion may, in a shorter time, increase the mass of a core to the pebble isolation mass.

description: We show how to extend the usual black string instability of vacuum or charged black p-branes to the anti-de Sitter background. The string fragments in an analogous fashion to the $Λ=0$ case, the main difference being that instead of a periodic array of black holes forming, an accumulation of ``mini'' black holes occurs towards the AdS horizon. In the case where the AdS space is of finite extent, such as an orbifold compactification, we show how the instability switches off below a certain compactification scale.

description: The U.S. Air Force proposes to install an underground fiber optic line between TPK-8 and the FAC Alpha Facility on FaC HIII on the Nellis Air Force Range. The length of this line is approximately 5 km (3.5 miles) and its proposed route parallels an existing improved gravel road for about 3. 7 km of that distance. The remaining portion of the line follows an unimproved dirt road. The proposed route was surveyed for cultural resources by a single pedestrian transect (30 m; 100 ft wide) along the flagged centerline. Four cultural resources (26NY8648, 26NY8782, 26NY8783, and 26NY8784) and three isolated artifacts were recorded during the reconnaissance. Two of the cultural resources (26NY8782 and 26NY8783) are recommended to be eligible for nomination to the National Register of Historic Places under criterion d of 36 CFR 60.4. The remaining cultural resources, including all isolated artifacts, are recommended as not being eligible for protection. It is apprised that the proposed installation of the fiber optic line will have no adverse effect on either historic property (26NY8782 or 26NY8783) as long as the route for this line is confined to previously disturbed areas through or adjacent to these properties.

We compute the one-loop contribution of the scalar to the quantum effective potential of the vierbein and find that it does not have GL(4) invariance. The minima of the effective potential occur for a vierbein which is proportional to the unit matrix.

Investigation of FACTS devices to improve power quality in distribution networks
Creators: name: Rehman Shaikh, Muhammad Asim
Publisher: name: Imperial College London
Year: 2010

description: Flexible AC transmission system (FACTS) technologies are power electronic solutions that improve power transmission through enhanced power transfer volume and stability, and resolve quality and reliability issues in distribution networks carrying sensitive equipment and non-linear loads. The use of FACTS in distribution systems is still in its infancy. Voltages and power ratings in distribution networks are at a level where realistic FACTS devices can be deployed. Efficient power converters and therefore loss minimisation are crucial prerequisites for deployment of FACTS devices. This thesis investigates high power semiconductor device losses in detail. Analytical closed form equations are developed for conduction loss in power devices as a function of device ratings and operating conditions. These formulae have been shown to predict losses very accurately, in line with manufacturer data. The developed formulae enable circuit designers to quickly estimate circuit losses and determine the sensitivity of those losses to device voltage and current ratings, and thus select the optimal semiconductor device for a specific application. It is shown that in the case of majority carrier devices (such as power MOSFETs), the conduction power loss (at rated current) increases linearly in relation to the varying rated current (at constant blocking voltage), but is a square root of the variable blocking voltage when rated current is fixed. For minority carrier devices (such as a pin diode or IGBT), a similar relationship is observed for varying current, however where the blocking voltage is altered, power losses are derived as a square root with an offset (from the origin). Finally, this thesis conducts a power loss-oriented evaluation of cascade type multilevel converters suited to reactive power compensation in 11kV and 33kV systems. The cascade cell converter is constructed from a series arrangement of cell modules. Two prospective structures of cascade type converters were compared as a case study: the traditional type which uses equal-sized cells in its chain, and a second with a ternary relationship between its dc-link voltages. Modelling (at 81 and 27 levels) was carried out under steady state conditions, with simplified models based on the switching function and using standard circuit simulators. A detailed survey of non punch through (NPT) and punch through (PT) IGBTs was completed for the purpose of designing the two cascaded converters. Results show that conduction losses are dominant in both types of converters in NPT and PT IGBTs for 11kV and 33kV systems. The equal-sized converter is only likely to be useful in one case (27-levels in the 33kV system). The ternary-sequence converter produces lower losses in all other cases, and this is especially noticeable for the 81-level converter operating in an 11kV network.

A Functionalised Aptamer Electrochemical Biosensor Platform
Creators: name: Zhang, Yangyang
Publisher: name: Imperial College London
Year: 2011

description: The ability to utilise new knowledge of biomarkers from genomic and proteomic data will have a great impact on molecular diagnosis. Biomarker detection could be achieved by utilising a capture molecule that associates specifically with the target biomarker. The work described in this thesis focuses on a platform comprising a lysozyme binding aptamer and an amperometric electrode (an electrochemical aptasensor). To couple the binding reaction to a change in current, the aptamer is modified with a redox group, ferrocene. Two types of signalling aptamer were constructed, one comprised the aptamer self-assembled on gold and hybridised to a short complementary oligonucleotide carrying a ferrocene group. The second incorporated the binding sequence into a molecular beacon, one end of which self-assembled onto the electrode, the other end carried the ferrocene group. Both of these showed a lysozyme dependent change in current on a gold electrode. Further characterisation of the first aptasensor suggested that the nucleic acid formed a multilayer structure on the electrode surface and that lysozyme binding induced conformational change moved ferrocene close to the surface, increasing the current. In contrast, the second aptamer usually showed a decrease in current in the presence of lysozyme suggesting that the binding resulted in the ferrocene moving away from the surface. In order to evaluate the possible use of these aptasensors for continuous in vivo measurement, needle shaped microelectrodes arrays were produced and the beacon aptamer immobilised on the surface. These electrodes had high impedance which resulted in low sensitivity, however lysozyme binding could still be detected using electrochemical impedance spectroscopy with ferrocyanide in solution. These microspike arrays could also be used for glucose sensing following modification with glucose oxidase.

description: The U.S. Air Force (USAF) proposes to install a 10.6 mile (17.1 km) long fiber optic line between the Tolicha Peak Compound and the top of Black Mountain (Figures 1 and 2). The proposed route was chosen to coincide with corridors of existing utility lines and other disturbance, as much as possible, in order to minimize potential effects to the overall environment and to known historic properties. All but 0.4 miles (1 acre) of the 10.2 miles follows previously-disturbed and previously-surveyed rights-of-way. The 0.4 mile undisturbed portion is a deviation from the existing corridor. The Desert Research Institute conducted a Class III survey along that proposed deviation and found no cultural resources.

description: In this paper we report the theory describing the electro-osmotic flow in charged nanopores with constant radius and charge density driven by alternating current. We solve the ion and solution transport in unsteady conditions as described by the Navier-Stokes and Nernst-Planck equations considering the electrical potential inside the charged nanopore uniform in the radial direction (Uniform Potential model approximation). We derive the transport equation system in the case in which the pore is connected to two boundary diffusion layers and the cations and anions have different diffusion coefficients. This approach allows the theoretical description of the characteristic frequency dependence of the phase shift between the applied current density and the electro-osmotic flow. Additionally we show how the analysis of the dynamic response of the electro-osmotic coupling factor versus the AC frequency allows us to quantify the apparent ion diffusion coefficient in membranes. Notably, the frequency window where the phase-shift is predicted is well inside the commonly used sampling rate for electro-osmotic flow experiments $f\in\left[10^{-4},10^1\right]$ Hz, hence the proposed method can be useful to determine the apparent diffusion coefficient of ions (such as redox complex for flow batteries) in charged membranes.

Restoring immune homeostasis in a mouse model of autoimmune arthritis
Creators: name: Somenzi, Olivier
Publisher: name: Imperial College London
Year: 2011

description: Rheumatoid arthritis (RA) is a chronic inflammatory disorder with features of autoimmunity whose exact aetiology remains unknown although interactions between genetic factors, sex hormones and environmental factors are thought to play a role. Recent data support the view that RA is a disease characterised by aberrant adaptive immune responses, imposed in part via defective pathways of T cell activation. SKG mice carry a mutation in the protein tyrosine kinase ZAP-70, leading to attenuated TCR signalling and activation, and develop an autoimmune inflammatory arthritis resembling human RA, mediated by T cells. The hypothesis behind this project is that reconstitution of TCR signalling in mature, peripheral arthritogenic SKG T cells can restore immune homeostasis, which in turn suppresses the disease process. Firstly, it was demonstrated that naïve Balb/c and ZAP-70 mutant SKG CD4+ T cells expressing a TCR transgene differentiate into distinct subsets of effector Th cells following stimulation with specific antigen in the absence of a polarising cytokine environment. Significantly, SKG effector T cells are deficient in IL-2, IL-4 and IFN-γ production during differentiation and become IL-17 high-producers, when compared to wild type Balb/c T cells. The mechanism through which defective TCR signalling in SKG T cells favours the generation of arthritogenic IL-17 expressing T cells was then investigated, using two complimentary approaches. The first approach sought to establish virus-mediated gene transfer protocols to compare the effects of reconstituting SKG T cells with wild type or mutant ZAP-70 on the development of arthritis in a T cell-mediated adoptive transfer model. Despite trying both lentiviral and retroviral vector approaches, the efficiency of gene transduction into target murine primary T cells was insufficient for further in vitro functional analysis or for testing the arthritogenicity of transduced T cells in adoptive transfer experiments. Using a second approach, I tested the effects of reconstituting in vitro the defects in cytokine expression observed during differentiation of SKG T cells. Notably, supplementation of differentiating SKG T cells with exogenous recombinant IL-2 inhibited the differentiation to IL-17 producing T cells. This effect was associated with repression of induction of RORc, the master transcriptional regulator of IL-17 gene expression. The effects of IL-2 supplementation were also tested in vivo in the adoptive transfer model and found to have a suppressive effects on disease severity and incidence.

description: We study the optimal performance of Carnot-like heat engines working in low dissipation regime using the product of the efficiency and the power output, also known as the efficient power, as our objective function. Efficient power function represents the best trade-off between power and efficiency of a heat engine. We find lower and upper bounds on the efficiency in case of extreme asymmetric dissipation when the ratio of dissipation coefficients at the cold and the hot contacts approaches, respectively, zero or infinity. In addition, we obtain the form of efficiency for the case of symmetric dissipation. We also discuss the universal features of efficiency at maximum efficient power and derive the bounds on the efficiency using global linear-irreversible framework introduced recently by one of the authors.

description: We derive the precise late-time asymptotics for solutions to the wave equation on extremal Reissner-Nordström black holes and explicitly express the leading-order coefficients in terms of the initial data. Our method is based on purely physical space techniques. We derive novel weighted energy hierarchies and develop a singular time inversion theory, which allow us to uncover the subtle contribution of both the near-horizon and near-infinity regions to the precise asymptotics. We introduce a new horizon charge and provide applications pertaining to the interior dynamics of extremal black holes. Our work confirms, and in some cases extends, the numerical and heuristic analysis of Lucietti-Murata-Reall-Tanahashi, Ori-Sela and Blaksley-Burko.

Analysis of Venous Blood Flow and Deformation in the Calf under External Compression
Creators: name: Wang, Ying
Publisher: name: Imperial College London
Year: 2011

description: Deep vein thrombosis (DVT) is a common post-operative complication, and a serious threat to the patient’s general recovery. In recent years, there has been increasing awareness of the risk of DVT in healthy individuals after prolonged immobility, such as people taking long-period flights or sitting at a computer. Mechanical methods of DVT prophylaxis, such as compression stockings, have gained widespread acceptance, but the haemodynamic mechanism of their action is still not well understood. In this study, computational modelling approaches based on magnetic resonance (MR) images are used to (i) predict the deformation of calf and deep veins under external compression, (ii) determine blood flow and wall shear stress in the deep veins of the calf, and (iii) quantify the effect of external compression on flow and wall shear stress in the deep veins. As a first step, MR images of the calf obtained with and without external compression were analysed, which indicated different levels of compressibility for different calf muscle compartments. A 2D finite element model (FEM) with specifically tailored boundary conditions for different muscle components was developed to simulate the deformation of the calf under compression. The calf tissues were described by a linear elastic model. The simulation results showed a good qualitative agreement with the measurements in terms of deep vein deformation, but the area reduction predicted by the FEM was much larger than that obtained from the MR images. In an attempt to improve the 2D FEM, a hyperelastic material model was employed and a finite element based non-rigid registration algorithm was developed to calculate the bulk modulus of the calf tissues. Using subject-specific bulk modulus derived with this method together with a hyperelastic material model, the numerical results showed better quantitative agreement with MR measured deformations of deep veins and calf tissues. In order to understand the effect of external compression on flow in the deep veins, MR imaging and real-time flow mapping were performed on 10 healthy volunteers before and after compression. Computational fluid dynamics was then employed to calculate the haemodynamic wall shear stress (WSS), based on the measured changes in vessel geometry and flow waveforms. The overall results indicated that application of the compression stocking led to a reduction in both blood flow rate and cross sectional area of the peroneal veins in the calf, which resulted in an increase in WSS, but the individual effects were highly variable. Finally, a 3D fluid-structure interactions (FSI) model was developed for a segment of the calf with realistic geometry for the calf muscle and bones but idealised geometry for the deep vein. The hyperelastic material properties evaluated previously were employed to describe the solid behaviours. Some predictive ability of the FSI model was demonstrated, but further improvement and validation are still needed.

Ionization dynamics in intense pulsed laser radiation. Effects of frequency chirping

description: Via a non-perturbative method we study the population dynamics and photoelectron spectra of Cs atoms subject to intense chirped laser pulses, with gaussian beams. We include above threshold ionization spectral peaks. The frequency of the laser is near resonance with the 6s-7p transition. Dominant couplings are included exactly, weaker ones accounted for perturbatively. We calculate the relevant transition matrix elements, including spin-orbit coupling. The pulse is taken to be a hyperbolic secant in time and the chirping a hyperbolic tangent. This choice allows the equations of motions for the probability amplitudes to be solved analytically as a series expansion in the variable u=(tanh(pi t/tau)+1)/2, where tau is a measure of the pulse length. We find that the chirping changes the ionization dynamics and the photoelectron spectra noticeably, especially for longer pulses of the order of 10^4 a.u. The peaks shift and change in height, and interference effects between the 7p levels are enhanced or diminished according to the amount of chirping and its sign. The integrated ionization probability is not strongly affected.

description: The proposed land wirhdrawal, if granted, should have an overall beneficial effect on the historic properties within the land parcels due to the restriction of public access. Recent recreational activities on White Sides have already affected the cultural resource at 26LN3761 by the removal of rocks to construct wind breaks and have affected both historic roads (26LN3218 and 26LN3985) which have been heavily traveled to gain access to the southern land parcel. An adverse effect of land withdrawal would be the restricted access to these sites for scientific study. It is recommended that the BLM develop a management plan for that portion of the Summit Spring Road that traverses BLM managed lands since this particular road appears to have played a key role in the early development of southern Nevada and Lincoln County.
On gauge fields - strings duality as an integrable system

description: It was suggested in hep-th/0002106, that semiclassically, a partition function of a string theory in the 5 dimensional constant negative curvature space with a boundary condition at the absolute satisfy the loop equation with respect to varying the boundary condition, and thus the partition function of the string gives the expectation value of a Wilson loop in the 4 dimensional QCD. In the paper, we present the geometrical framework, which reveals that the equations of motion of such string theory are integrable, in the sense that they can be written via a Lax pair with a spectral parameter. We also show, that the issue of the loop equation rests solely on the properly posing the boundary condition.

description: The project is a proposed Nevada Bell fiber optic cable burial route, 51.2 miles in length by 25 feet in width. The route extends between Centel-owned underground facilities located at the corner of Ann Road and U.S. Highway 95 on the southeast, to just northeast of the junction of Mercury Road and US Highway 95 on the northwest, where the new service will enter the Nevada Test Site. In addition, a short stretch of line on BLM administered lands will reach from Nevada Bell's Specter Mountain repeater onto the Nevada Test Site.
Spatial and temporal signatures of ecological constraints on diversity
Creators: name: McInnes, Lynsey
Publisher: name: Imperial College London
Year: 2011

description: Broad-scale diversity patterns are the outcome of ecological and evolutionary processes that permit different numbers of species to coexist in a region. Many studies have focused on understanding the factors that allow a region to contain more species or a clade to diversify more rapidly. In this thesis, I shift focus to instead explore the constraints that prevent biodiversity increasing unbounded, using a combination of phylogenetic and biogeographical approaches across a range of temporal and spatial scales. In chapter two, I investigate conservatism (i.e., the tendency for more closely related species to be more similar) in the extremes of climate tolerated by a species, assessing the hypothesis that tightly-conserved tolerances are influential in determining the range extents of the species. By using global data from two vertebrate classes and a range of climatic variables, I assess the taxonomic generality of this hypothesis and identify the most strongly conserved variables. In chapters three and four, I develop novel macroecological analyses of factors that may limit the extent of geographic ranges and apply them to Afrotropical birds (chapter three) and all continental mammals (chapter four). Chapter five assesses how the spatial distribution of range limits can be used to compare species’ relative abilities to occupy available landscape. In chapter six, I present new methods to detect signals of past changes to diversity limits in phylogenies, using simulations to explore the power of phylogenies to reveal such patterns of diversity-dependent cladogenesis. In addition to the main research chapters, I append a synthetic review, of which I am joint first author, exploring the evolutionary underpinnings of large-scale species-area relationships. This thesis builds links between the macroecology of species’ distributions with the dynamics of clades over macroevolutionary timescales to determine how geography, phylogeny and history interact in the generation and maintenance of large-scale biodiversity.

description: Objective: The objective of this study was to evaluate the experimental effects of exercise on memory function among adults with mild cognitive impairment (MCI). Methods: A systematic review and meta-analysis were employed. Studies were identified using electronic databases, including PubMed, PsychInfo, SPORTDiscus, and Google Scholar. To be eligible for inclusion, studies had to employ an experimental design, be conducted in humans (no animal models) with mild cognitive impairment, include an exercise intervention arm (either acute exercise or chronic training), and measure memory function (any type) as the outcome measure. Comprehensive Meta-Analysis software was used to compute the standardized mean difference effect size (Cohen’s d) and 95% CI using a random-effects model. Results: In total, 11 studies met our criteria, contributing to 20 effect size estimates. Among the 20 effect size estimates, 13 contributed to a short-term memory recall, with 7 contributing to a delayed/long-term memory recall. The overall weighted mean effect size was d = 0.30 (95% CI: 0.16–0.44; P Q = 0.004, df(1), P = 0.95), as exercise (vs. control) demonstrated both short-term (d = 0.31; 95% CI: 0.14–0.47; P d = 0.29; 95% CI: 0.06–0.53; P = 0.013) benefits. Conclusion: Current evidence suggests that exercise may help to improve memory function among those with MCI. Safe and progressive forms of exercise should be promoted among MCI patients.
A functional approach to estimation of the parameters of generalized negative binomial and gamma distributions

description: The generalized negative binomial distribution (GNB) is a new flexible family of discrete distributions that are mixed Poisson laws with the mixing generalized gamma (GG) distributions. This family of discrete distributions is very wide and embraces Poisson distributions, negative binomial distributions, Sichel distributions, Weibull--Poisson distributions and many other types of distributions supplying descriptive statistics with many flexible models. These distributions seem to be very promising for the statistical description of many real phenomena. GG distributions are widely applied in signal and image processing and other practical problems. The statistical estimation of the parameters of GNB and GG distributions is quite complicated. To find estimates, the methods of moments or maximum likelihood can be used as well as two-stage grid EM-algorithms. The paper presents a methodology based on the search for the best distribution using the minimization of $\ell^p$-distances and $L^p$-metrics for GNB and GG distributions, respectively. This approach, first, allows to obtain parameter estimates without using grid methods and solving systems of nonlinear equations and, second, yields not point estimates as the methods of moments or maximum likelihood do, but the estimate for the density function. In other words, within this approach the set of decisions is not a Euclidean space, but a functional space.

description: The project area is located in Indian Springs, Clark County, Nevada, within T16S, R56E, Section 9 (Figure 2). It is a 17.4‐acre, roughly rectangular parcel bounded on three sides by Creech AFB and on the fourth (south) side by a frontage road paralleling the north side of US Highway 95 (US 95). Spatial definition of the project area was generated by digitizing a project map provided by Nellis AFB, combined with refinement using tax assessor parcel boundaries. The parcel is privately owned, but is scheduled to be acquired and incorporated into the surrounding Creech AFB property. Presently, there are several commercial and residential buildings on the property, as can be seen in the aerial view in Figure 3, including a gas station and Indian Springs Casino.
