description: Strong interplay of spin and charge/orbital degrees of freedom is the fundamental characteristic of the iron-based superconductors (FeSCs), which leads to the emergence of a nematic state as a rule in the vicinity of the antiferromagnetic state. Despite intense debate for many years, however, whether nematicity is driven by spin or orbital fluctuations remains unsettled. Here, by use of transport, magnetization, and $^{75}$As nuclear magnetic resonance (NMR) measurements, we show a striking transformation of the relationship between nematicity and spin fluctuations (SFs) in Na$_{1-x}$Li$_x$FeAs; For $x\leq 0.02$, the nematic transition promotes SFs. In contrast, for $x\geq 0.03$, the system undergoes a non-magnetic phase transition at a temperature $T_0$ into a distinct nematic state that suppresses SFs. Such a drastic change of the spin fluctuation spectrum associated with nematicity by small doping is highly unusual, and provides insights into the origin and nature of nematicity in FeSCs.

Data reduction algorithms to enable long-term monitoring from low-power miniaturised wireless EEG systems
Creators: name: Logesparan, Lojini
Publisher: name: Imperial College London
Year: 2012

description: Objectives: The weight and volume of battery-powered wireless electroencephalography (EEG) systems are dominated by the batteries. Battery dimensions are in turn determined by the required energy capacity, which is derived from the system power consumption and required monitoring time. Data reduction may be carried out to reduce the amount of data transmitted and thus proportionally reduce the power consumption of the wireless transmitter, which dominates system power consumption. This thesis presents two new data selection algorithms that, in addition to achieving data reduction, also select EEG containing epileptic seizures and spikes that are important in diagnosis. Methods: The algorithms analyse short EEG sections, during monitoring, to determine the presence of candidate seizures or spikes. Phase information from different frequency components of the signal are used to detect spikes. For seizure detection, frequencies below 10 Hz are investigated for a relative increase in frequency and/or amplitude. Significant attention has also been given to metrics in order to accurately evaluate the performance of these algorithms for practical use in the proposed system. Additionally, signal processing techniques to emphasize seizures within the EEG and techniques to correct for broad-level amplitude variation in the EEG have been investigated. Results: The spike detection algorithm detected 80% of spikes whilst achieving 50% data reduction, when tested on 992 spikes from 105 hours of 10-channel scalp EEG data obtained from 25 adults. The seizure detection algorithm identified 94% of seizures selecting 80% of their duration for transmission and achieving 79% data reduction. It was tested on 34 seizures with a total duration of 4158 s in a database of over 168 hours of 16-channel scalp EEG obtained from 21 adults. These algorithms show great potential for longer monitoring times from miniaturised wireless EEG systems that would improve electroclinical diagnosis of patients.

description: In many domains, the previous decade was characterized by increasing data volumes and growing complexity of computational workloads, creating new demands for highly data-parallel computing in distributed systems. Effective operation of these systems is challenging when facing uncertainties about the performance of jobs and tasks under varying resource configurations, e.g., for scheduling and resource allocation. We survey predictive performance modeling (PPM) approaches to estimate performance metrics such as execution duration, required memory or wait times of future jobs and tasks based on past performance observations. We focus on non-intrusive methods, i.e., methods that can be applied to any workload without modification, since the workload is usually a black-box from the perspective of the systems managing the computational infrastructure. We classify and compare sources of performance variation, predicted performance metrics, required training data, use cases, and the underlying prediction techniques. We conclude by identifying several open problems and pressing research needs in the field.

Perspectives on the role of bioenergy for distributed heat and power generation
Creators: name: Pantaleo, Antonio Marco
Publisher: name: Imperial College London
Year: 2013

description: The thesis assesses the potential of bioenergy to serve the heat and power demands through a series of case studies in bioenergy systems modelling, and proposing a holistic approach to draw general conclusions about the drivers, threats and trends of bioenergy for stationary applicatons. The overarching aim is the assessment of the key factors for the penetration of bioenergy into energy systems, with a specific focus on urban areas. For this purpose, a generic framework for the spatially explicit optimization of the variety of bioenergy chains and infrastructures is proposed. The methodology is based on a multi-objective mixed integer linear programming optimization and allows investigating: (i) the trade-off between distributed and centralized plants; (ii) the optimal location and sizing of storage/processing platforms to serve decentralized plants; (iii) the optimal temporal planning of biomass supply; (iv) the potential for integration of bioenergy routes into existing energy infrastructures. In order to address the issues of biomass supply chain and inform the bio-energy modeling tool, a general methodology is proposed and applied to techno-economic feasibility studies of small scale CHP routes; the energy potential assessment, techno-economic analysis and plant sizing methodologies could be generalized to other case studies. Moreover, as an example of optimal integration of bioenergy into existing energy systems, a specific focus on gas/biomass dual fuel microturbines is provided, through a methodology for optimal planning and operation of small scale CHP and an application to thermo-economic assessment of on site 100 kWe CHP systems. Finally, in order to address some issues that are not captured by quantitative optimization modeling approaches, biomass ESCOs business models are investigated to evaluate the main key factors and barriers influencing the ESCO operations in the market segment of biomass heating and CHP. Some representative case studies are proposed in the Italian scenario.

description: Objective: To apply a causal analysis approach to estimate the intent-to-treat and per-protocol effects in a safety outcome study of the 30-day risk of liver injury associated with antibiotic use (macrolides, penicillin-based antibiotics, and fluoroquinolones). Research design and methods: For each antibiotic class, we constructed a pooled cohort of treated episodes matched with untreated episodes using an electronic medical record database from a university hospital. High-dimensional propensity scores were calculated using baseline patient characteristics, concomitant medications and medical history as surrogate confounders. Intent-to-treat hazard ratios (HRs) were estimated using inverse probability of treatment weighted discrete hazard models that ignored subsequent treatment changes. Per-protocol HRs were calculated using inverse probability of treatment and censoring weighted models after terminating each episode’s observation at the first treatment change. Results: For macrolides, the intent-to-treat HR (95% confidence interval) was 1.22 (0.75–1.98) and the per-protocol HR was 1.22 (0.67–2.22). For penicillin-based antibiotics, the intent-to-treat HR was 4.01 (3.16–5.08) and the per-protocol HR was 7.25 (5.58–9.41). For fluoroquinolones, the intent-to-treat HR was 1.60 (1.27–2.03) and the per-protocol HR was 1.69 (1.23–2.30). Conclusion: Researchers should clearly define the target estimands, and carefully estimate and interpret both effects.

description: This deliverable D1.2 of the LIFT project forms the second phase in the establishment of the LIFT farm typology depending on ecological practices. The purpose was to gather the opinion of local stakeholders in different case studies, in order to understand the current state of existing typologies and to collect their recommendations for the development of the LIFT typology that was initiated with a literature review in LIFT Deliverable D1.1. The qualitative study in the current deliverable D1.2 was carried out using face-to-face interviews or workshops with two or three stakeholders. A diversity of stakeholders was interviewed through a qualitative questionnaire. Twenty one stakeholders from five different case study areas participated. Four major themes were covered during the interviews: 1) typologies that stakeholders know, use and design; 2) stakeholders’ opinion on the practices that should be considered to capture the degree of ecological farming; 3) stakeholders’ interest in a user-friendly tool to assign a farm to a farming system through a specific typology of ecological practices; and 4) stakeholders’ opinion on the LIFT typology. This study reveals key elements to integrate in the development of the LIFT typology and the LIFT typology-tool. For example, all stakeholders recognised in their area one or more farming systems proposed by the LIFT typology, but also indicated that it is difficult to use this typology as it is, given the potential overlaps between different systems. They suggested the use of summary indicators e.g. taking into account the use of fossil energy.

description: We describe a model-independent method of assessing the uncertainties in cross-correlation lags determined from AGN light curves, and use this method to investigate the reality of lags between UV and optical continuum variations in well-studied AGNs. Our results confirm the existence of such lags in NGC 7469. We find that the continuum variations at 1825 A, 4845 A, and 6962 A follow those at 1315A by 0.22^{+0.12}_{-0.13} days, 1.25^{+0.48}_{-0.35} days, and 1.84^{+0.93}_{-0.94} days, respectively, based on the centroids of the cross-correlation functions; the error intervals quoted correspond to 68% confidence levels, and each of these lags is greater than zero at no less than 97% confidence. We do not find statistically significant interband continuum lags in NGC 5548, NGC 3783, or Fairall 9. Wavelength-dependent continuum lags may be marginally detected in the case of NGC 4151. However, on the basis of theoretical considerations, wavelength-dependent continuum lags in sources other than NGC 7469 are not expected to have been detectable in previous experiments. We also confirm the existence of a statistically significant lag between X-ray and UV continuum variations in the blazar PKS 2155-304.

Multi-Agent System Control and Coordination of Distributed Energy Resources in Electrical Power Networks
Creators: name: Collins, Mark
Publisher: name: Imperial College London
Year: 2013

description: The central question to be addressed in this thesis is whether Active Network Management (ANM) implemented through a Multi-Agent System (MAS) can offer a realistic basis for managing a distribution network of the future. These networks will contain many more Distributed Energy Resources (DER) than present networks resulting in a more regular occurrence of constraints being violated because of the network’s increased usage. A review of ANM schemes is presented in order to show their impact on the global and local operation of distribution networks, the economic impacts and benefits they have, and the limitations that arise from the centralisation of operations. This thesis shows that a distributed MAS implementation of ANM could potentially remove limitations associated with a centralised approach to ANM. However, present MAS ANM approaches raise concerns with regards to their operation on realistic networks, the communication burden they create, the safety and security of their operation and the economic considerations taken when implementing decisions. This thesis proposes a MAS ANM scheme with an agent allocated to every node of the network, implementing a fully decentralised decision making algorithm. These agents are all peers and use message propagation so voltage approximations can be calculated and DER corrective actions shared without the need for a complete, central network model to exist. Agents select a beneficial control action to satisfy voltage constraints in order to minimise corrective costs associated with the DER actions. This is achieved by combining the cost of various DER corrective actions and a cost allocated to voltage excursions outside the target control range. This approach removes the need for a central moderator, avoiding potential single point failures and reducing communication overheads of present MAS ANM schemes. Furthermore to ensure this MAS ANM does not affect the present GB energy market operation, the cost associated with DER corrective actions reflects the real revenue incurred by DER owners and compensated by the MAS ANM scheme operator. Finally to confirm that the MAS ANM meets the main aim of the thesis, it is shown to successfully operate upon many test distribution network configurations, rapidly bring voltage excursions from load changes back within limits. The solutions found are comparable to an Optimal Power Flow (OPF) supplied with a full network model and set of DER costs, confirming its ability to provide similar results to centralised ANM schemes with the benefits over the operational limitations of proposed centrally moderated MAS ANM schemes.
The Computational Enhancement of Automated Non-Destructive Inspection
Creators: name: Brierley, Nicholas
Publisher: name: Imperial College London
Year: 2014

description: In industrial NDE it is increasingly common for data acquisition to be automated, driving a recent substantial increase in the availability of data. The collected data need to be analysed and currently this is largely done manually by a skilled operator - a rather painstaking task given how rarely defects occur. Moreover, in automated NDE a region of an inspected component is typically interrogated several times, be it within a single data channel due to multiple probe passes, across several channels acquired simultaneously or over the course of repeated inspections. The systematic combination of these diverse readings is recognised to offer an opportunity to improve the reliability of the inspection, for example by enabling noise suppression, but is not achievable in a manual analysis. Hence there is scope for the inspection reliability to be improved whilst reducing the time taken for the data analysis by computational means. This thesis describes the development of a software framework providing a partial automation capability, aligning then fusing the available experimental data to declare regions of the component defect-free to a very high probability whilst readily identifying indications, thereby optimising the use of the operator's time. The framework is designed to be applicable to a wide range of automated NDE scenarios, but the focus in development has been on two distinct, industrial inspections: the ultrasonic inspection of power station turbine rotor bores and the ultrasonic immersion inspection of aerospace turbine disks. Results obtained for industrial datasets from these two applications convincingly demonstrate the benefits of using the developed software system.

description: In this paper, with two-dimensional (2-D) hybrid simulations, we study the generation mechanism of filamentary structures downstream of a quasi-parallel shock. The results show that in the downstream both the amplitude of magnetic field and number density exhibit obvious filamentary structures, and the magnetic field and number density are anticorrelated. Detailed analysis find that these downstream compressive waves propagate almost perpendicular to the magnetic field, and the dominant wave number is around the inverse of ion kinetic scale. Their parallel and perpendicular components roughly satisfies(where and represent the parallel and in-plane perpendicular components of magnetic field, is the wave number in the perpendicular direction, and in the ion gyroradius), and their Alfven ratio also roughly agree with the analytical relation (where and indicate the Alfven ratio and plasma beta), while the corresponding cross helicity and compressibility show good agreement with previous theoretical calculations. All these properties are consistent with those of kinetic slow waves (KSWs). Therefore, we conclude that the filamentary structures in the downstream of a quasi-parallel shock are produced due to the excitation of KSWs.

The spreadsheet is organized into key categories such as Governance Structure, Organizational Structure, Ethical Considerations, Risk Management, and Security, among others. Each category is broken down into subcategories and specific assessment statements. Organizations evaluate their current state using a three-level scale: Fully Implemented, Partially Implemented, or Not Implemented. The tool consolidates the results by category and subcategory, and uses tables and charts to visualize the level of readiness. This Excel file serves as the operational artifact supporting the research project based on the Design Science Research (DSR) methodology.
Porous Melt-Derived Bioactive Glass Scaffolds for Bone Regeneration via Gel-Cast Foaming
Creators: name: Tang, Hok Man
Publisher: name: Imperial College London
Year: 2013

description: Scaffolds suitable for trabecular bone regeneration were produced via the gel-cast foaming process using the melt-derived glass composition SBP-3. A problem common to most bioactive glass compositions that undergo sintering in order to achieve scaffold form is that they crystallise, lowering bioactivity as well as incurring mechanical instability of the structure via unpredictable local degradation. The scaffolds did not exhibit significant bulk crystallisation upon sintering and the presence of potassium sodium sulphate crystals were not detected on the surface, which were formed with a previously studied composition ICIE16. The process was then optimised further and up-scaled to produce scaffolds in sufficient quantities for an in vivo ovine condyle defect study (undertaken at University College London by Prof. Allen Goodship and Prof. Gordon Blunn). Despite possessing a relatively high network connectivity - 2.31 - and low bioactivity from SBF studies, results from the in-vivo study concluded that the SBP-3 scaffolds performed better than the original 45S5 Bioglass granules, displaying 99 % bone aposition over a period of 91 days, in addition to the new bone more closely resembling the trabecular bone structure. Work was then carried out to simplify the process, switching from a chemical polymerisation process to a thermal gelation process, thus allowing for greater optimisation of the process.

description: The non commutative geometry is a possible framework to regularize Quantum Field Theory in a nonperturbative way. This idea is an extension of the lattice approximation by non commutativity that allows to preserve symmetries. The supersymmetric version is also studied and more precisely in the case of the Schwinger model on supersphere [14]. This paper is a generalization of this latter work to more general gauge groups.

description: We employ an algebraic approach for unifying perturbative and non-perturbative superstring states on an equal footing, in the form of U-duality multiplets, at all excited string levels. In compactified type-IIA supertring theory we present evidence that the multiplet is labelled by two spaces, ``index'' space and ``base'' space, on which U acts without mixing them. Both spaces are non-perturbative extensions of similar spaces that label perturbative T-duality multiplets. Base space consists of all the central charges of the 11D SUSY algebra, while index space corresponds to represetations of the maximal compact subgroup K in U. This structure predicts the quantum numbers of the non-perturbative states. We also discuss whether and how U-multiplets may coexist with 11-dimensional multiplets, that are associated with an additional non-perturbative 11D structure that seems to be lurking behind in the underlying theory.

We successfully measure time delays for eight of the nine sources, and find values ranging from about two weeks to a little over two months. Combining the measured lags and widths of the variable parts of the emission lines allows us to make virial mass estimates for the active nucleus in each galaxy. The virial masses are in the range 10^{7-8} solar masses.

TGF-beta family ligands in autophagy and muscle wasting

description: Chronic Obstructive Pulmonary Disease (COPD) is a collective term for emphysema, chronic bronchitis, and obstructive bronchiolitis, which is caused by chronic tobacco smoke exposure. COPD is a multi-system disease; skeletal muscle is one such system that is dysfunctional in a significant proportion of COPD patients. Muscle weakness and wasting is observed in COPD patients, with fibre type changes as well as fibre atrophy reported. Skeletal muscle as a target for pharmacotherapy in COPD as exercise training improves life expectancy and quality of life in patients. Loss of protein contributes to muscle atrophy; however, the mechanisms and signalling pathways involved in protein degradation are not fully understood. Autophagy is a protein degradation pathway implicated in muscle atrophy. Additionally, the TGF-β superfamily member -myostatin and FHL1 are signalling molecules of interest. The cytokine myostatin is a recognised inhibitor of muscle growth, whilst FHL1 is an adaptor protein usually associated with hypertrophy in muscle. The data presented herein focuses on three aspects: the effect of myostatin on autophagy, the interaction between myostatin and FHL1 in atrophy and the effect of smoke exposure on autophagy. Furthermore, the effects of other atrophy associated signalling molecules (growth differentiation factor 15, GDF-15 and angiotensin-II, ang-II) on these themes were examined. The data show that myostatin is a novel inducer of autophagy indicating that myostatin can induce protein degradation through autophagy. FHL1 augmented myostatin induced signalling in vitro and in vivo, suggesting a potential mechanism by which type II fibres are more susceptible to atrophy than others and helping to account for the fibre type changes and atrophy in COPD. The role of smoke exposure of autophagy remains unclear; however, GDF-15 may be involved in muscle atrophy. Ang-II did not induce autophagy in vivo and inhibition of angiotensin signalling had no effect on autophagy in COPD patients.

description: Nano and bulk-forms of zinc oxide (ZnO) are used extensively in industry and consequently may accumulate in the environment. However, there is little information available on the comparative effects of these forms during the critical early stages of plant life. Furthermore, the role of chelating agents, which affect the bioavailability of metals, in ameliorating plant stress due to exposure to nano and bulk-forms of ZnO is not well characterised. In this study, the effects of different concentrations (0.5, 2.5, 5, 10, 50 and 100 ppm) of nano ZnO (22 nm) and bulk ZnO (natural form, 1000 nm) with and without organic (citrate) and inorganic (EDTA) chelators on germination and seedling growth, and oxidative stress markers of Nicotiana tabacum L. were compared. Chelators (without ZnO) enhanced root growth, whilst ZnO negatively affected seedling growth. ZnO toxicity was often mitigated by adding chelators, especially citrate, although at the highest levels (50 and 100 ppm) of ZnO, toxicity was more pronounced when chelated with EDTA, but was decreased with citrate. Collectively, our findings provide important information regarding the different morpho-physiological and biochemical effects of bulk and nano ZnO and organic and inorganic chelators (citrate and EDTA), which are all prevalent in the environment.

description: The semiclassical approximation of the worldline path integral is a powerful tool to study nonperturbative electron-positron pair creation in spacetime-dependent background fields. Finding solutions of the classical equations of motion, i.e. worldline instantons, is possible analytically only in special cases, and a numerical treatment is nontrivial as well. We introduce a completely general numerical approach based on an approximate evaluation of the discretized path integral that easily and robustly gives the full semiclassical pair production rate in nontrivial multi-dimensional fields, and apply it to some example cases.

Carborane containing conjugated polymers for use in organic electronics
Creators: name: Marshall, Jonathan
Publisher: name: Imperial College London
Year: 2014

description: Organic semiconductors have emerged as potential replacements for inorganic materials based on several promising advantages, such as their low-cost, high-throughput fabrication and tolerance for flexible substrates. While these attributes ensure that the use of organic semiconductors is appealing, further improvements in electronic performance and stability are still required. This work focuses on the design, synthesis and analysis of a novel range of organic semiconductors incorporating carborane units. Carboranes possess unusual properties which, in principle, make them highly attractive species to incorporate into optoelectronically active materials, although they have been largely untested as components of organic electronic devices. An uncommon three-dimensional delocalised bonding motif infers upon carboranes extreme thermal and chemical stability and a strong electron-withdrawing nature, traits that, if correctly exploited, could potentially lead to organic semiconductors with improved stabilities and optimised electronic properties. This thesis reports a number of approaches to the incorporation of carborane into semiconducting polymers. In the first, ortho-carborane is directly fused to the aromatic backbone via both carbon atoms. The novel difunctionalisation of benzocarborane, and its subsequent incorporation into two previously unreported polymer systems, is reported. Copolymerisation with electron-rich and electron-poor comonomers established that the incorporation of benzocarborane did not prevent electronic delocalisation along the polymer backbone, and that it acted as a mildly electron withdrawing comonomer. P-type behaviour in organic field effect transistors was observed. Based on these results, a second-generation monomer unit was synthesised, incorporating two fused thienyl rings and facilitating observable improvements in molecular ordering and charge-transporting behaviour. The second approach focuses on the attachment of carborane to the conjugated polymer backbone via the functionalisation of one of its carbon atoms, either directly or via a vinylene spacer. Hence carborane functionalised benzodithiophene monomers were prepared via a novel method of carborane C-arylation, before subsequent polymerisation with a range of electron accepting comonomers. The resultant polymers demonstrate OFET performance higher than that reported for non-carborane containing equivalents and exhibit promising solar cell performance. The final chapter details the attachment of various carboranes onto two polythiophene systems via a vinylene linker. Through careful consideration of carborane and vinyl bond stereochemistries, and pendant group spacing it was observed that optical, material, OFET and OPV properties of the resultant polymers could be controlled.

description: Studies of cold material through IRAS 60um and 100um observations indicated that half of ordinary E and E/S0 galaxies were detected above the 3 sigma level, indicating that cold gas is common, although no correlation was found between the optical and far- infrared fluxes. Most detections were near the instrumental threshold, and given an improved understanding of detection confidence, we reconsider the 60um and 100um detection rate. After excluding active galactic nuclei, peculiar systems, and background contamination, only 15 non-peculiar E and E/S0 galaxies from the RSA catalog are detected above the 98% confidence level, about 12% of the sample. An unusually high percentage of these 15 galaxies possess cold gas (HI, CO) and optical emission lines (Halpha), supporting the presence of gas cooler than 10E4 K. The 60um to 100um flux ratios imply a median dust temperature for the sample of 30 K, with a range of 23-38 K. These detections define the upper envelope of the optical to far-infrared relationship, F_fir propto F_B^0.24+/-0.08, showing that optically bright objects are also brighter in the infrared, although with considerable dispersion. A luminosity correlation is present with L_fir propto L_B^1.65+/-0.28, but the dust temperature is uncorrelated with luminosity. Models that contain large dust grains composed of amorphous carbon plus silicates come close to reproducing the typical 60um to 100um flux ratios, the far-infrared luminosity, and the L_fir - L_B relationship.

description: We collate active galactic nuclei (AGN) with reported detections of both relativistic reflection and ultra-fast outflows. By comparing the inclination of the inner disc from reflection with the line-of-sight velocity of the outflow, we show that it is possible to meaningfully constrain the geometry of the absorbing material. We find a clear relation between the velocity and inclination, and demonstrate that it can potentially be explained either by simple wind geometries or by absorption from the disc surface. Due to systematic errors and a shortage of high- quality simultaneous measurements our conclusions are tentative, but this study represents a proof-of-concept that has great potential.

description: The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized that the joint processing of the narrative in the text and the visual narrative in the illustrations could make the comic format more effective for acquiring and remembering scientific information. Two experiments were conducted using explicit and inferential question types to compare performance between comics, illustrated texts, and text-only materials. Both verbatim and applied question types were included to see if performance changed based on the type of mental representation required to answer questions correctly. Image recognition checks revealed poor target-lure discrimination ability, which suggests that participants were not focusing on illustrated text images when presented. Null findings from these experiments may have implications for theory and future studies.
