Stopped Light in Passive and Active Plasmonic and Metamaterial Waveguides
Creators: name: Pickering, Timothy William
Publisher: name: Imperial College London
Year: 2013

description: The phenomena of slow and stopped light have attracted a growing interest in recent years, not only in relation to fundamental physics but also due to the possibility to enhance the density of states over a broad bandwidth. In this thesis the effects of both loss and gain on slow and stopped light are investigated in a representative metamaterial and plasmonic waveguide setting, using both semi-analytic calculations and numerical time-domain simulations. Initially the influence of material loss on the ability to stop light in these passive structures is considered. By directly measuring the propagation of wavepackets it is demonstrated that extremely low group velocities, with deceleration factors of the order of 200,000, can be achieved even in the presence of realistic material loss, resolving a previous dispute that this would not be possible. It is further shown that stopped light in the plasmonic waveguide is robust to low levels of surface roughness, currently a limiting factor in other slow light devices such as photonic crystal waveguides. The inclusion of gain materials into the waveguides is then investigated for loss compensation. Here full compensation of losses and even amplification of the modal fields is observed while maintaining zero group velocities. Importantly for the metamaterial waveguide it is found that the effective negative refractive index is maintained even in the amplification regime, as previously it had been suggested this would not be possible. Finally it is shown that in the amplification regime stopped light provides an inherent feedback mechanism leading to the dynamic formation of a lasing mode. The properties of these stopped-light lasing states are studied and it is shown that subwavelength localisation of the modal fields can be achieved, thus presenting a new route to creating nanoscale light sources.

description: L'objectif de la campagne WACS (West Africa Cold Seeps) était d'étudier le fonctionnement et la diversité des écosystèmes associés aux sources de fluides froids dans le Golfe de Guinée à partir de l'étude multidisciplinaire  de quelques structures actives sur les marges du Congo, de l'Angola et du Gabon. La campagne était basée sur une stratégie multi-échelles. A l'échelle locale il s'agissait d'analyser les relations entre les associations biologiques et l'hétérogénéité de l'habitat, en intégrant l'étude des adaptations faunistiques à un habitat contraignant, une estimation quantitative des flux de méthane, et de poursuivre une démarche temporelle en collaboration avec nos partenaires allemands. A l'échelle régionale (Golfe de Guinée) les communautés colonisent différentes structures géologiques actives (pockmarks, diapirs). Nous avions pour objectif de rechercher les relations entre structures géologiques et communautés, et les échanges génétiques entre les zones étudiées.La seconde partie de la campagne était dédiée à l'exploration de deux zones profondes en bas de pente et dans les lobes terminaux du chenal du Congo, afin de déterminer si les communautés à base chimiosynthétique repérées dans ces zones sont liées au recyclage superficiel de matière organique d'origine terrestre ou à des remontées de méthane depuis des réservoirs profonds. La faune de ces environnements réducteurs sera comparée à celle des structures géologiques actives et les flux géniques éventuels entre les zones seront estimés.À l'échelle océanique (radiale équatoriale atlantique - AEB en collab. Avec nos partenaires américains), nous avions pour objectif les parentés entre espèces homologues des sources hydrothermales et « cold-seeps », pour en inférer les voies de dispersion et les barrières biogéographiques, les cas de co-évolution dans les associations pérennes.Le projet de rattachement est le Projet Ifremer "Biodiversité et fonctionnement des écosystèmes profonds, impacts".

description: The weak decay as well as the strong nucleon coupling constants of the isoscalar axial vector meson $f_1 (1285)$ are estimated within the octet quark model. It is shown that the empirical value for the coupling of $\overline{s}s$ quarkonium to nucleons can be understood by attributing the $f_1(1285)$-nucleon coupling to the $a_0πN$ triangle diagram.

“Smart” Self-Assembled β-Sheet Poly (γ-glutamic acid) Hybrid Hydrogels
Creators: name: Clarke, David
Publisher: name: Imperial College London
Year: 2013

description: Hybrid materials have been found to be possessed with unique and novel properties, by superimposing the advantages of each component to provide material properties far superior to the individual constituents alone. These types of material are used throughout the field of bioengineering, and can facilitate biological interactions on both a molecular and cellular level, responding to biological and mechanical queues. With these inherent unique properties these materials provide novel platforms to help repair, replace and regenerate body tissues and function. This thesis explores the synthesis of new “smart” hybrid hydrogels and their properties. Through the conjugation of self-assembling β-sheet peptide sequences to a naturally occurring poly (γ-glutamic acid) polymer backbone, peptide-polymer hybrid hydrogels were formed. These hybrid hydrogels were attributed with robust and tunable mechanical properties. Through the reassembly of the physical β-sheet crosslinks the hydrogels can respond to their mechanical environment, exhibiting “self-healing” capabilities and a resistance to cyclic strain. Also, being composed entirely of natural peptide bonds they have excellent biocompatibility and are a promising platform for future tissue engineering scaffolds and biomedical applications. These hybrid hydrogels were further functionalised to detect for the activity of enzymatic biomarkers. A simple assay based on Förster resonance energy transfer was incorporated in to the hydrogel platform through the immobilisation of quantum dots modified with peptide substrates. The activity of matrix metalloproteinase-7 was targeted specifically, a marker for inflammation and immunity. This hydrogel sensing platform provides a basis for the in vivo sensing of enzymes and also, the potential to be used as a powerful tool to investigate biological processes in vitro.

description: A wave of Omicron infections rapidly emerged in China in 2022, but large-scale data concerning the safety profile of vaccines and Coronavirus disease 2019 (COVID-19) infection features in liver transplant (LT) recipients have not been collected. Therefore, the aim of this study was to assess the protectiveness and safety profile of the inactivated vaccines in LT patients against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infections. A multi-center retrospective study was conducted in a cohort with a history of liver transplantation. Electronic questionnaires were used to collect data on demographics, vaccination information, history of liver transplantation, and characteristics of COVID-19 infection until June 2022. The vaccine information included number of doses, vaccine type, injection time, and adverse events. A total of 1881 participants (487 vaccinated and 1394 unvaccinated patients) were enrolled from seven centers in China. Fourteen of the participants were infected by Omicron, and 50% patients had over 14 days of viral shedding duration. The protection rate of COVID-19 vaccinations to Omicron was 2.59%. The three breakthrough infections occurred more than 6 months after fully vaccinated. A total of 96 (19.7%) vaccinated patients had adverse events, including fatigue, myalgia, liver dysfunction, swelling, and scleroma. There were more Grade 3 adverse events in the preoperative vaccination group than those in the postoperative vaccination group. Inactivated whole-virion SARS-CoV-2 vaccines are safe in patients with post-liver transplantation. The efficacy of inactivated vaccines decreases after 6 months of vaccination, it is recommended that liver transplant patients get boosted vaccinations as early as possible even when they are fully vaccinated. Although clinical manifestations of Omicron infections were mild in LT patients, unvaccinated patients might have a higher risk of liver dysfunction during infections.
Equivalent width, shape and proper motion of the iron fluorescent line emission from the molecular clouds as an indicator of the illuminating source X-ray flux history

description: Observations of the diffuse emission in the 8--22 keV energy range, elongated parallel to the Galactic plane (Sunyaev et al. 1993) and detection of the strong 6.4 keV fluorescent line with $\sim$ 1 keV equivalent width from some giant molecular clouds (e.g. Sgr B2) in the Galactic Centre region (Koyama 1994) suggest that the neutral matter of these clouds is (or was) illuminated by powerful X-ray radiation, which gave rise to the reprocessed radiation. The source of this radiation remains unknown. Transient source close to the Sgr B2 cloud or short outburst of the X-ray emission from supermassive black hole at the Galactic Centre are the two prime candidates under consideration. We argue that new generation of X-ray telescopes combining very high sensitivity and excellent energy and angular resolutions would be able to discriminate between these two possibilities studying time dependent changes of the morphology of the surface brightness distribution, the equivalent width and the shape of the fluorescent line in the Sgr B2 and other molecular clouds in the region. We note also that detection of broad and complex structures near the 6.4 keV line in the spectra of distant AGNs, which are X-ray weak now, may prove the presence of violent activity of the central engines of these objects in the past. Accurate measurements of the line shape may provide an information on the time elapsed since the outburst. Proper motion (super or subluminal) of the fluorescent radiation wave front can give additional information on the location of the source. Observations of the described effects can provide unique information on the matter distribution inside Sgr B2 and other giant molecular clouds.

description: Existing attention mechanisms either attend to local image grid or object level features for Visual Question Answering (VQA). Motivated by the observation that questions can relate to both object instances and their parts, we propose a novel attention mechanism that jointly considers reciprocal relationships between the two levels of visual details. The bottom-up attention thus generated is further coalesced with the top-down information to only focus on the scene elements that are most relevant to a given question. Our design hierarchically fuses multi-modal information i.e., language, object- and gird-level features, through an efficient tensor decomposition scheme. The proposed model improves the state-of-the-art single model performances from 67.9% to 68.2% on VQAv1 and from 65.7% to 67.4% on VQAv2, demonstrating a significant boost.

It is shown that the extraction of the radiative capture cross sections $^7Be(p,\ γ)^8B$ which are relevant for the solar neutrino problem is not affected appreciably by Coulomb reacceleration. A non-perturbative model is used for the purpose. Emphasis is put on the perspectives for future experiments which are planned at the University of Notre Dame, RIKEN (Japan), and GSI (Germany). An analysis of the total yields of ``photon-point" processes in inelastic electron scattering is also done.

The role of complex II of the mitochondrial respiratory chain in cell death induction
Creators: name: Hwang, Ming
Publisher: name: Imperial College London
Year: 2014

description: Complex II of the respiratory chain (RC) recently emerged as a prominent regulator of cell death. In both cancer as well as neurodegenerative diseases, mutations in its subunits have been found along with other genetic alterations indirectly affecting this complex. Moreover, anticancer compounds were developed that target complex II and cause cell death in a tumour-specific way. I found evidence that this protein assembly is specifically activated for cell death via the dissociation of its SDHA and SDHB subunits from the membrane-anchoring proteins through mitochondrial Ca2+ influx. The relationship between Ca2+ and cell death activation has been under intense investigation, but not much has been identified on the associated mechanisms. Ca2+ influx into mitochondria plays a significant role in cell death induction, but it was unknown how the observed massive Ca2 accumulation activates the organelle for cell destruction. The disintegration of complex II subunits is prevented in vitro when cardiolipin is substituted with a lipid devoid of Ca2+ binding. Cardiolipin is known to associate with complex II, but coalesces into tight homotypic clusters upon Ca2+ binding. When complex II is deprived of this lipid, it disintegrates for ROS formation and cell death induction. My results reveal Ca2+ binding to cardiolipin and subsequent complex II disintegration as a crucial step for oxidative stress and cell death induction. Ultimately, it emphasizes the important role that Ca2+ plays in ROS-induced cell death via the respiratory chain, which can be used for many translational investigations. For instance, future studies on Ca2+ and its binding to cardiolipin for cell death induction will further elucidate complex II as a target for cancer treatment as well as neurodegenerative diseases and reveal its role as a nexus for many diverse stimuli in cell death signalling.

Using fMRI to investigate speech production in healthy adults and patients with post-stroke aphasia
Creators: name: Geranmayeh, Fatemeh
Publisher: name: Imperial College London
Year: 2015

description: This thesis presents an investigation of brain networks mediating both language-specific and domain-general control of propositional speech production in health and following left hemisphere stroke. The research used univariate and multivariate analyses of functional magnetic resonance imaging data as participants produced sentential speech in response to stimuli (Speech). The activity of specific brain networks during Speech was compared against different baseline conditions. Two studies on healthy participants confirmed a language-specific role for a left fronto-temporo-parietal (LFTP) network. Propositional speech was accompanied by a relative suppression of activity in domain-general networks including a right fronto-temporo-parietal (RFTP) network, default mode network (DMN), and cingulo-opercular (CingOper) network. A separate study investigated alterations in the activity of these networks following a chronic left hemisphere stroke. The network measures in patients were related to those from the healthy participants. There was an up-regulation of the CingOper network during Speech, a task the patients found difficult. Although the activity within individual networks was not predictive of speech production in patients, the relative activity between networks was a predictor of both within-scanner and out-of-scanner performance, over and above that predicted from lesion volume and various demographic factors. Specifically, the robust functional imaging predictors were the differential activity between the DMN and both the left and right fronto-temporo-parietal networks. The patients also demonstrated an altered speech-related between-networks functional connectivity. A further study of cerebrovascular reactivity measurements suggested that signal changes in the healthy tissue remote from the infarct were unlikely to be confounded by cerebrovascular reactivity changes following stroke. The results of the thesis indicate that recovery of speech production after stroke, is not adequately captured by notions of brain regions ‘taking over’ lost domain-specific functions. Rather it is best considered as the interaction between what remains of domain-specific networks and the domain-general systems that regulate behaviour.

description: Brightest Cluster Galaxies (BCGs) in massive dark matter halos are shaped by complex merging processes. We present a detailed stellar population analysis in the central region of Abell 3827 at $z\sim0.1$, including five-nucleus galaxies involved in a BCG assembly. Based on deep spectroscopy from Multi Unit Spectroscopic Explorer (MUSE), we fit the optical spectra of 13 early-type galaxies (ETGs) in the central 70 kpc of the cluster. The stellar populations in the central $R=1$ kpc of these ETGs are old (6-10 Gyr). Their [Fe/H] increases with $σ_{\star}$ and stellar mass. More importantly, [$α$/Fe] of galaxies close to the cluster center do not seem to depend on $σ_{\star}$ or stellar mass, indicating that the cluster center shapes the [$α$/Fe]-$σ_{\star}$ and [$α$/Fe]-$M_{\star}$ relations differently than other environments where [$α$/Fe] is observed to increase with increasing $σ_{\star}$ or $M_{\star}$. Our results reveal the coordinated assembly of BCGs: their building blocks are different from the general low mass populations by their high [$α$/Fe]. Massive galaxies thus grow by accreting preferentially high [$α$/Fe] systems. The radial profiles also bear the imprint of the coordinated assembly. Their declining [Fe/H] and flat [$α$/Fe] radial profiles confirm that the accreted systems have low metallicity and high [$α$/Fe] stellar contents.

description: La diversification de l’agriculture est indispensable. Elle peut conduire à des rendements plus élevés et plus stables, à une diminution du changement d’usage des sols et à une réduction de l’utilisation de produits chimiques nocifs.

Dans un contexte agricole et alimentaire tendu, la transition du système alimentaire vers des processus et pratiques plus soutenables est souvent remise en question. Une série de découvertes en écologie et en agriculture suggère que la biodiversité, tant spécifique que génétique, peut aider à résoudre les problèmes de durabilité auxquels est confrontée l’agriculture intensive moderne. De la parcelle au pays, cette étude démontre les avantages apportés par une diversification des cultures (variétale, spécifique, paysagère) par rapport à l’agriculture intensive conventionnelle. 

La modernisation de l’agriculture a entraîné une réduction de la diversité génétique des espèces utilisées. Celle-ci est pourtant la clé pour une agriculture plus adaptée au changement climatique, à une nutrition plus équilibrée, à des pratiques plus durables pour l’environnement et la santé humaine. Cette diversification permet des rendements plus élevés et plus stables, un moindre recours aux engrais et aux pesticides, un besoin moins important en terres cultivables et des apports nutritionnels plus équilibrés.

description: We compute the $\mathcal{N}=1$ superconformal blocks from the networks of open Wilson lines in the $\text{osp}(1|2)$ Chern-Simons theory in the expansion of large central charge $c$. We first reproduce the $1/c$ correction of conformal weight from an open Wilson line by adopting the regularization prescription developed in our previous works. We then obtain the closed form expressions of superconformal blocks including $1/c$ corrections, which were not available before. We also examine heavy operators corresponding to supersymmetric conical spaces, and the geometry is quantized by utilizing the coadjoint orbits of the super Virasoro group. Superconformal blocks involving these operators are also examined.

Design, fabrication and testing of miniaturized neural recording platform for robotic applications in fly sensorimotor research

description: Blowflies are exquisite fliers and have long been established as models for sensorimotor research. Their flight performance crucially depends on both visual and mechanoreceptive feedback. Our understanding of how the nervous system integrates signals of these sensory modalities, however, leaves two important issues unresolved. First: As most experiments are performed on restrained animals, how are neural signals integrated when the animal actually moves? Second: Are neural mechanisms underlying optic-flow-based self-motion estimation modulated by mechanosensory modalities when controlling motor behaviour? To address these questions, I have designed a mobile platform and miniaturized electrophysiological recording equipment. Here, I describe details of the platform’s mechanical and electronic components, test its performance, and demonstrate that it enables high quality recordings from an identified interneuron in the fly motion vision pathway, the H1-cell, which is believed to process optic-flow, generate during self-motion. I compare the recordings obtained with my novel platform to those gathered with much bigger setups, which are orders of magnitude heavier, and characterize the responses of the H1-cell under various stimulus conditions. My results are mostly in agreement with earlier work but include new findings on pattern size-dependent responses of the cell, which are in contrast to theoretical predictions based on previous behavioural and physiological studies. To investigate how the fly uses signals from different sensory modalities to control various optomotor behaviours and potentially vision-based collision avoidance, I have established a brain machine interface on a small mobile robot that uses the neural activity of the H1-cell to control the robot's motor system. In summary, I have created a platform for in vivo recordings of neural activity in flies on a small robot. This novel technology will enable further studies on multisensory integration to gain new insights into the design of fly sensorimotor pathways involved in course control and collision avoidance.

Design, synthesis and characterisation of conjugated polymers containing reactive functionality for organic photovoltaics

description: The nanoscale morphology of the active layer in organic photovoltaic devices is critical to their performance. Blend morphologies can be manipulated by using a variety of additives, co-solvents and by thermal annealing. However, one crucial issue for any organic photovoltaic device is operational lifetime, which is largely dictated by changes in the active layer morphology. Such changes may be due to reordering of the polymer material, or diffusion and aggregation of fullerene derivatives to a more thermodynamically stable state. This reordered structure can potentially have detrimental effect by losses in interfacial surface area and an increase in exciton recombination. Many novel polymers are designed without this consideration and may be susceptible to this type of degradation. Herein, we explore a variety of approaches to stabilise the blend morphology, principally by the incorporation of various reaction functionalities onto the polymer backbone. The three main areas which have been investigated are; varying of acceptor strengths, chain end modifications with various crosslinking chemistries and thermally cleavable leaving groups. Firstly, poly(dithienogermole-benzothiadiazole) analogues are synthesised to investigate how changes to the acceptor strength of the D-A co-polymers will affect the bulk heterojunction morphology and polymer performance. Then the synthesis and functionalisation of benzotriazole in poly(cyclopentadithiophene-benzotriazole) with alkyl bromine crosslinking groups and thienopyrroledione in poly(dithienogermole-thienopyrroledione), with both alkyl bromide & alkyl oxetane crosslinking groups was investigated. Further studies will investigate the effects on material and optoelectronic properties as well as device performance in OPV and suitability of additives with crosslinking. Lastly, we explore the incorporation of thermal cleavable BOC groups on thienopyrroledione, in poly(cyclopentadithiophene-thienopyrroledione), the deprotection of Boc in polymeric materials and its effects on material and optoelectronic properties.

description: We report results of analysis of the ASCA observation of 1993, May 7th of the dipping LMXB source XBT 0748-676, and propose a new explanation of the spectral evolution in dipping in this source. We show that the non-dip and dip spectra in several intensity bands are well fitted using the same physical model that we have previously shown gives good explanations of several dipping sources, consisting of point source blackbody emission from the neutron star, plus extended Comptonised emission from the accretion disk corona (ADC), with progressive covering of the ADC during dipping. Best fit values of kT_bb = 1.99 +/- 0.16 keV and power law photon index Gamma = 1.70 +/- 0.16 are found. The strong excess below 1 keV was well fitted by a Gaussian line at ~0.65 keV. In dipping, good fits were obtained by allowing it to be covered by the same progressive covering factor as the extended continuum emission, providing strong evidence that the line originates in the ADC. By using our two-component model we show that the unabsorbed component is the uncovered fraction of the Comptonised emission, and in the band 1 - 10 keV, we do not need to invoke substantial electron scattering to explain dipping.

description: This paper takes a comprehensive view on the protocol stacks that are under debate for a future Internet of Things (IoT). It addresses the holistic question of which solution is beneficial for common IoT use cases. We deploy NDN and the two popular IP-based application protocols, CoAP and MQTT, in its different variants on a large-scale IoT testbed in single- and multi-hop scenarios. We analyze the use cases of scheduled periodic and unscheduled traffic under varying loads. Our findings indicate that (a) NDN admits the most resource-friendly deployment on nodes, and (b) shows superior robustness and resilience in multi-hop scenarios, while (c) the IP protocols operate at less overhead and higher speed in single-hop deployments. Most strikingly we find that NDN-based protocols are in significantly better flow balance than the UDP-based IP protocols and require less corrective actions.
