description: Four operating neutrino observatories confirm the long standing discrepancy between detected and predicted solar neutrino flux. Among these four experiments the Homestake experiment is taking data for almost 25 years. The reliability of the radiochemical method for detecting solar neutrinos has been tested recently by the GALLEX experiment. All efforts to solve the solar neutrino problem by improving solar, nuclear, and neutrino physics have failed so far. This may also mean that the average solar neutrino flux extracted from the four experiments may not be the proper quantity to explain the production of neutrinos in the deep interior of the Sun. Occasionally it has been emphasized that the solar neutrino flux may vary over time. In this paper we do address relations among specific neutrino fluxes produced in the proton-proton chain that are imposed by the coupled systems of non-linear partial differential equations of solar structure and kinetic equations by focusing our attention on a statistical interpretation of selected kinetic equation of PPII/PPIII branch reactions of the proton-proton chain. A fresh look at the statistical implications for the outcome of kinetic equations for nuclear reactions may shed light on recent claims that the $^7$Be-neutrino flux of the Sun is suppressed in comparison to the pp- and $^8$B neutrino fluxes and may hint at that the solar neutrino flux is indeed varying over time as shown by the Homestake experiment.

Multi-games and bayesian nash equilibriums
Creators: name: Ghoroghi, Ali
Publisher: name: Imperial College London
Year: 2015

description: A growing awareness of the prominent role the environment plays in multi-agent systems has led to gradual acceptance of its importance by the multi-agent system community in general. Within this line of research, we propose a new class of games, called Multi-Games. A Multi-game is one in which a given number of players play a fixed finite number of basic games simultaneously. The basic games in a multi-game can be regarded as different environments for the players, and, in particular, we submit that multi-games can be used to model investment in multiple national and continental markets within a global economy. Furthermore, when the players' weights for different games in the multi-game are classed as private information or as types with given conditional probability distributions, we obtain a particular class of Bayesian games. The main contribution of this thesis is to illustrate how, for the class of so-called completely pure regular multi-games with finite sets of types, the Nash equilibria of the basic games can be used to compute a Bayesian Nash equilibrium in multi-games, with complexity independent of the number of types. Following the presentation of the main results, the thesis presents two algorithms that allow us to establish whether we have a Bayesian Nash equilibrium which can be determined with lower computational complexity.
An Optical/Near-Infrared Study of Radio-Loud Quasar Environments I. Methods and z=1-2 Observations

description: We have conducted an optical/near-infrared study of the environments of radio-loud quasars (RLQs) at redshifts z=0.6-2. In this paper we discuss the sample selection and observations for the z=1-2 subsample and the reduction and cataloguing techniques used. We discuss technical issues at some length, since few detailed descriptions of near-IR data reduction and multicolor object cataloguing are currently available in single literature references. Our sample of 33 RLQs contains comparable numbers of flat- and steep- radio spectrum sources and sources of various radio morphologies, and spans a similar range of absolute magnitude and radio power, allowing us to disentangle dependence of environment on such properties from redshift evolution. We use the standard ``shift-and-stare'' method of creating deep mosaiced images where the exposure time (and thus the RMS noise) at each pixel is not constant across the mosaic. An unusual feature of our reduction procedure is the creation of images with constant RMS noise from such mosaics. We adopted this procedure to enable use of the FOCAS detection package over almost the entire mosaic instead of only in the area of deepest observation where the RMS noise is constant, thereby roughly doubling our areal coverage. We correct the object counts in our fields for stellar contamination using the SKY model of Cohen (1995) and compare the galaxy counts to those in random fields. Even after accounting for possible systematic magnitude offsets we find a significant excess of K>=19 galaxies. Analysis and discussion of this excess population is presented by Hall & Green (1998).

description: Ontology Matching aims to find the semantic correspondences between ontologies that belong to a single domain but that have been developed separately. However, there are still some problem areas to be solved, because experts are still needed to supervise the matching processes and an efficient way to reuse the alignments has not yet been found. We propose a novel technique named Reverse Ontology Matching, which aims to find the matching functions that were used in the original process. The use of these functions is very useful for aspects such as modeling behavior from experts, performing matching-by-example, reverse engineering existing ontology matching tools or compressing ontology alignment repositories. Moreover, the results obtained from a widely used benchmark dataset provide evidence of the effectiveness of this approach.

Numerical modelling of stiff clay cut slopes with nonlocal strain regularisation
Creators: name: Summersgill, Freya
Publisher: name: Imperial College London
Year: 2014

description: The aim of this project is to investigate the stability of cut slopes in stiff clay. The findings are subsequently applied to model stabilisation with piles, used to remediate failure of existing slopes and stabilise potentially unstable slopes created by widening transport corridors. Stiff clay is a strain softening material, meaning that soil strength reduces as the material is strained, for example in the formation of a slip surface. In an excavated slope this can lead to a progressive, brittle slope failure. Simulation of strain softening behaviour is therefore an important aspect to model. The interaction of piles and stiff clay cut slopes is investigated using the Imperial College Geotechnics section’s finite element program ICFEP. In designing a suitable layout of the finite element mesh, preliminary analyses found the two existing local strain softening models to be very dependent on the size and arrangement of elements. To mitigate this shortcoming, a nonlocal strain softening model was implemented in ICFEP. This model controls the development of strain by relating the surrounding strains to the calculation of strain at that point, using a weighting function. Three variations of the nonlocal formulation are evaluated in terms of their mesh dependence. A parametric study with simple shear and biaxial compression analyses evaluated the new parameters required by the nonlocal strain softening model. The nonlocal results demonstrated very low mesh dependence and a clear improvement on the local strain softening models. In order to examine the mesh dependence of the new model in a boundary value problem compared to the local strain softening approach, excavated slope analyses without piles were first performed. The slope was modelled in plane strain with coupled consolidation. These analyses also investigated other factors such as the impact of adopting a small strain stiffness material model on the development of the failure mechanism and the impact of the spatial variation of permeability on the time to failure. The final set of analyses constructed vertical stabilisation piles in the excavated slope, represented as either solid elements or one dimensional beam elements. The development of various failure mechanisms for stiff clay cuttings was found to be dependent on pile location, pile diameter and pile length. This project provides an insight into the constitutive model and boundary conditions required to study stabilisation piles in a stiff clay cutting. The nonlocal model performed very well to reduce mesh dependence, confirming the biaxial compression results. However, the use of coupled consolidation was found to cause further mesh dependence of the results.

Characterisation of cellular responses to pandemic influenza in naturally infected individuals

Publisher: name: Imperial College London

description: Understanding the relevance of T cells in limiting influenza illness severity will facilitate the rational design and evaluation of T cell-based universal influenza vaccines. The aim of this thesis was to characterise pre-existing T cell responses to influenza and follow the kinetics of these T cell responses to infection by exploiting the 2009 H1N1 pandemic (pH1N1). Peripheral blood mononuclear cells (PBMCs) were collected from healthy adults naïve to pH1N1 who were longitudinally followed over 2 influenza seasons from 2009 – 2011. Ex vivo pH1N1-specific memory CD4+ and CD8+ T cell responses were characterised by IFN-γ/IL-2 fluorescence-immunospot and 14-colour flow cytometry. In pH1N1 seronegative adults in a community setting, pre-existing influenza-specific T cells cross-reacting with pH1N1 were prevalent, pre-dominantly of a single-cytokine positive (IFN-γ+, IL-2+ or TNF-α+) and effector memory (CD45RA-CCR7-) or late effector (CD45RA+CCR7-) phenotype and expressed lung homing receptor (CCR5+) and cytotoxic degranulation marker (CD107ab+). Pre-existing CD8+IFN-γ+IL-2- Temra (CD45RA+CCR7-) cells limited disease severity following incident pH1N1 infection in the absence of protective strain-specific antibodies. Furthermore, we show that this protection-associated T cell subset is durably maintained in the absence of re-infection up to 1.5 years post-infection. The identification of a protection-associated immune correlate, the frequencies of which were increased and durably maintained by natural infection, is highly relevant for the development of a universal influenza vaccine inducing long-lasting, protective T cells.

description: The damped Lyman alpha systems seen in the spectra of high redshift QSOs offer the means to determine element abundances in galaxies observed while still at an early stage of evolution. Such measurements, which have only recently come within reach, complement and extend the data provided by studies of different stellar populations in our Galaxy and of extragalactic H~II regions which have up to now formed the basis of galactic chemical evolution models. In this paper we demonstrate the potential of this new approach with high-resolution echelle observations of several elements in the z(abs) = 2.27936 absorption system in the bright z(em) = 2.940 QSO 2348-147. The absorbing galaxy appears to be chemically unevolved, with heavy element abundances only 1/100 of solar; if it is the progenitor of a spiral galaxy like our own, it is unlikely to have collapsed to form a thin disk by z = 2.3 (corresponding to a look-back time of approximately 13 Gyr for H_0 = 50 km/s/Mpc and q_0 = 0.01). Our data allow us to measure the nitrogen-to-oxygen ratio at a metallicity lower than those of the most metal-poor dwarf galaxies known. We find that, relative to the solar scale, N is more underabundant than O by at least a factor of 15. This result is broadly in line with current ideas on the relative importance of primary and secondary production of N; future measurements in several damped Lyman alpha systems will permit more stringent tests of models for the evolution of the N/O ratio with time. Oxygen and other alpha-elements are overabundant relative to Fe by no more than the factor of about 3 typical of metal-poor stars in the disk and halo of the Milky Way.

Worst-case resource-usage analysis of java card classic editions application bytecode
Creators: name: Urquhart, Luke Dominic Mark
Publisher: name: Imperial College London
Year: 2016

description: Java Card is the dominant smartcard technology in use today, with over 12 billion Java Card smartcards having shipped globally in the last 15 years. Almost exclusively, the deployed Java Card smartcards are instances of a Classic edition for which garbage collection is an optional component in even the most recent Classic edition. Poorly written or malicious Java Card applications may drain the available memory of a Java Card Virtual Machine to the point the card becomes unusable, and undisciplined use of the transaction mechanism may exhaust the available transaction buffers, resulting in programmatic abort by the Java Card Runtime Environment and so limit the range of services a Java Card application may successfully be able to offer. Given the size and global nature of the user base, and the commercial importance of Java Card, there is a stunning lack of tools supporting analysis or certification of the memory, transactional or CPU usage of Java Card applications. In this thesis we present a worst-case resource-usage analysis tool for Java Card which is capable of producing worst-case memory usage and worst-case execution-time estimates for Java Card applications (also known as applets). Our main theoretical contribution is a static analysis for Java Card applets at the bytecode level which conservatively approximates properties of interest affecting memory usage, input-output/APDU usage and transaction usage. Our static analysis provides the high-level information for subsequent worst-case resource-usage analysis in our tool which exploits well-known results and techniques from hard real-time systems. We generate a resource usage graph per registered applet lifecycle method entry point as the start node and the control-flow returning to the Java Card Runtime Environment as the final node. We use the Implicit Path Enumeration Technique to generate and solve Integer Linear Programming problems representing the worst-case memory-usage and worst-case execution-time.

description: The galaxy intrinsic alignment (IA) is a major challenge of weak lensing cosmology. To alleviate this problem, Zhang (2010, MNRAS, 406, L95) proposed a self-calibration method, independent of IA modeling. This proposal relies on several scaling relations between two-point clustering of IA and matter/galaxy fields, which were previously only tested with analytical IA models. In this paper, these relations are tested comprehensively with an $N$-body simulation of $3072^3$ simulation particles and boxsize 600 $h^{-1} \, \mathrm{Mpc}$. They are verified at the accuracy level of $\mathcal{O}(1)\%$ over angular scales and source redshifts of interest. We further confirm that these scaling relations are generic, insensitive to halo mass, weighting in defining halo ellipticities, photo-$z$ error, and misalignment between galaxy ellipticities and halo ellipticities. We also present and verify three new scaling relations on the B-mode IA. These results consolidate and complete the theory side of the proposed self-calibration technique.

description: Changing ocean conditions are driving distribution shifts in many marine species on a global scale, which will have major ecological implications for marine environments. I investigated the recent trend of increased silver hake (Merluccius bilinearis) abundances within the Gulf of St. Lawrence to characterize their biology in their northernmost extent. I assessed the diet and distribution of silver hake, as well as the overlap between the diet and distribution of silver hake with those of two resident species, Greenland halibut (Reinhardtius hippoglossoides) and redfish (Sebastes sp.). Silver hake’s diet in the Gulf was primarily benthic, with smaller contributions from pelagic prey than in diets reported along other parts of their range. Overlaps of diet and distribution between silver hake and the two highly abundant resident species were also high. I analyzed otoliths from the silver hake samples to investigate the age structure and growth of hake in the Gulf of St. Lawrence. Hake’s age structure in the Gulf is similar to that of nearby regions where most individuals are age four or younger, while von Bertalanffy growth rates showed higher rates of growth and lower asymptotic lengths in the Gulf compared to hake from the Scotian Shelf and Northeast United States Shelf. My results provide some of the first descriptions of silver hake biology within the Gulf of St. Lawrence.

description: We investigate the consistency of visual morphological classifications of galaxies by comparing classifications for 831 galaxies from six independent observers. The galaxies were classified on laser print copy images or on computer screen produced from scans with the Automated Plate Measuring (APM) machine. Classifications are compared using the Revised Hubble numerical type index T. We find that individual observers agree with one another with rms combined dispersions of between 1.3 and 2.3 type units, typically about 1.8 units. The dispersions tend to decrease slightly with increasing angular diameter and, in some cases, with increasing axial ratio $(b/a)$. The agreement between independent observers is reasonably good but the scatter is non-negligible. In spite of the scatter the Revised Hubble T system can be used to train an automated galaxy classifier, e.g. an Artificial Neural Network, to handle the large number of galaxy images that are being compiled in the APM and other surveys.

description: A complete flux-limited sample of 118 ultraluminous infrared galaxies (ULIGs) has been identified from the IRAS Faint Source Catalog (FSC). The selection criteria were a 60 micron flux density greater than 1 Jy in a region of the sky delta > -40 deg, |b| > 30 deg. All sources were subsequently reprocessed using coadded IRAS maps in order to obtain the best available flux estimates in all four IRAS wavelength bands. The maximum observed infrared luminosity is L_ir = 10^{12.90} L_{sun}, and the maximum redshift is z = 0.268. The luminosity function for ULIGs over the decade luminosity range L_ir = 10^{12} - 10^{13} L_{sun} can be approximated by a power law Phi (L) ~= L^{-2.35} Mpc^{-3} mag^{-1}. In the local Universe z < 0.1, the space density of ULIGs appears to be comparable to or slightly larger than that of optically selected QSOs at comparable bolometric luminosities. A maximum likelihood test suggests strong evolution for our sample; assuming density evolution proportional to (1+z)^{alpha} we find alpha = 7.6+/-3.2. Examination of the two-point correlation function shows a barely significant level of clustering, xi (r) = 1.6 +/- 1.2, on size scales r ~= 22 h^{-1} Mpc.

description: We review the quantitative science that can be and has been done with redshift and peculiar velocity surveys of galaxies in the nearby universe. After a brief background setting the cosmological context for this work, the first part of this review focuses on redshift surveys. The practical issues of how redshift surveys are carried out, and how one turns a distribution of galaxies into a smoothed density field, are discussed. Then follows a description of major redshift surveys that have been done, and the local cosmography out to 8,000 km/s that they have mapped. We then discuss in some detail the various quantitative cosmological tests that can be carried out with redshift data. The second half of this review concentrates on peculiar velocity studies, beginning with a thorough review of existing techniques. After discussing the various biases which plague peculiar velocity work, we survey quantitative analyses done with peculiar velocity surveys alone, and finally with the combination of data from both redshift and peculiar velocity surveys. The data presented rule out the standard Cold Dark Matter model, although several variants of Cold Dark Matter with more power on large scales fare better. All the data are consistent with the hypothesis that the initial density field had a Gaussian distribution, although one cannot rule out broad classes of non-Gaussian models. Comparison of the peculiar velocity and density fields constrains the Cosmological Density Parameter. The results here are consistent with a flat universe with mild biasing of the galaxies relative to dark matter, although open universe models are by no means ruled out.

Development of novel biosensing and diagnostic platforms using nanoparticle complexes

description: Metal nanomaterials, such as gold nanoparticles (Au NPs), exhibit unique localised surface plasmon resonance, which can be exploited for probing biochemical and biophysical phenomena at the nanoscale and molecular level. Furthermore, the ability to control the synthesis and growth of such nanomaterials using organic and biomimetic molecules, such as nucleic acids and small molecules, facilitates deeper understanding of the interactions between biomolecules and nanomaterials. This thesis described the development of various highly sensitive and novel diagnostic platforms for detecting micro-RNA (miRNA), small molecule and protein biomarkers, by utilising the unique plasmonic properties of Au NPs, as well as modulating the morphology and size of various gold nanostructures. Au NP-conjugated nucleic acid probes, together with a poly(ethylene glycol)-functionalised microarray, enabled highly sensitive and multiplexed detection of miRNAs, conveniently under an optical microscope. Also, colorimetric detection of small molecules using the naked eye was achieved via the controlled growth of aptamer-functionalised Au NPs into various distinct nanostructures, which were dependent on aptamer–target interactions and aptamer-mediated NP growth. Lastly, the interactions between small molecules and Au seeds, and the effect on the size and aspect ratios of grown gold nanorods were investigated and elucidated. The size-modulating mechanism was further incorporated in an immunoassay for the sensitive detection of a protein biomarker, enabling its application in clinical diagnostics. The platforms developed in this thesis could serve as a basis for future development of new biosensing strategies that utilise plasmonic nanomaterials.

description: This is the second paper in a series discussing the properties of ultraluminous infrared galaxies (ULIGs: L_ir > 10^{12} L_sun; Ho = 75 km s^{-1} Mpc^{-1} and qo = 0.0) from the 1-Jy sample of Kim (1995). This paper presents the first results of a spectroscopic survey at optical wavelengths of a randomly selected subset of 45 ULIGs from Kim & Sanders (1997). These new data are combined with previous data from Veilleux et al. (1995) to determine the spectral properties of luminous infrared galaxies (LIGs) with L_ir ~= 10^{10.5}-10^{13} L_sun. We find that the fraction of Seyfert galaxies among LIGs increases dramatically above L_ir ~= 10^{12.3} L_sun --- nearly half of the galaxies with L_ir > 10^{12.3} L_sun present Seyfert characteristics. Many of the optical properties of these Seyfert galaxies are consistent with the presence of a genuine active galactic nucleus (AGN) in the core of these objects. The continuum colors and strengths of the stellar H-beta and MgIb features in and out of the nuclei of ULIGs indicate that star formation has recently (~10^7 yr) taken place in the nuclear and circumnuclear regions of many of these objects. As expected, photoionization by hot stars appears to be the dominant source of ionization in the objects with H II region-like spectra. Evidence is presented that the ionization source in infrared-selected galaxies with nuclear LINER-like spectra (38% of the ULIGs in our sample) is likely to be shocks or of stellar origins rather than an AGN. Shock ionization associated with starburst-driven outflows may also explain the LINER-like emission detected outside the nuclei of some galaxies.

description: The unique ability of slot and sub-wavelength grating (SWG) waveguides to confine light outside of the waveguide core material has attracted significant interest in their application to chemical and biological sensing. However, high sensitivity to sidewall roughness induced scattering loss in these structures compared to strip waveguides casts doubt on their efficacy. In this article, we seek to settle the controversy by quantitatively comparing the sensing performance of various waveguide geometries through figures of merit that we derive for each mode of sensing. These methods take into account both modal confinement and roughness scattering loss, the latter of which is computed using a volume-current (Green's-function) method with a first Born approximation. For devices based on the standard 220 nm silicon-on-insulator (SOI) platform whose propagation loss is predominantly limited by random line-edge sidewall roughness scattering, our model predicts that properly engineered TM-polarized strip waveguides claim the best performance for refractometry and absorption spectroscopy, while optimized slot waveguides demonstrate >5x performance enhancement over the other waveguide geometries for waveguide-enhanced Raman spectroscopy.

Mechanism of interpersonal sensorimotor interaction
Creators: name: Takagi, Atsushi
Publisher: name: Imperial College London
Year: 2015

description: This thesis uncovers the mechanism of interaction between human partners in continuous contact. During such sensorimotor interaction, I propose that people interpret their partner's desired movement through the forces they feel. The evidence of this interpersonal goal integration mechanism comes from three behavioural experiments and computational modelling of their results. Novel dual-robotic interfaces were used in the experiments for two reasons: first, to eliminate the partner's gaze as it was found to influence the behaviour of interacting pairs of subjects. Second, to systematically and quantitatively measure the effects of sensorimotor interaction on task performance and adaptations in muscular activity, i.e. motor force and joint impedance. The first experiment revealed that sensorimotor interaction during a tracking task, where partners track a randomly moving target with their cursor, enabled both the worse and better partners in the pair to improve at tracking. This mutually beneficial effect of interaction, regardless of the partner's skill, cannot be explained by existing theories in psychology and neuroscience, but the discovered interpersonal goal integration mechanism does capture this behaviour; when this interaction mechanism was implemented in a robot partner, people interacting with this robot behaved similarly to those during interpersonal interaction. Adaptations in the muscular activity were observed in the second experiment, where pairs were rigidly or weakly coupled during a tracking task. The better partners increased their motor force and joint impedance, whereas the worse partners decreased both. The interaction mechanism also predicted these changes in the motor force. Finally, an experiment where four partners interacting together during a tracking task showed that the best partner's performance was not hindered by many worse partners, which was also predicted by the interpersonal goal integration mechanism. The interpersonal goal integration mechanism is the first robotic algorithm to exhibit human-like behaviour during sensorimotor interaction. It has applications where continuous contact with a human partner is critical, such as the transport of large objects or in the co-operative control of lower-limb exoskeletons. It offers a new approach for robotic rehabilitation through continuous, physical interaction which exploits the benefits of simultaneous action observation and physical training. Finally, the interaction mechanism may be used as an investigative and therapeutic tool for autism spectrum disorder (ASD). Individuals affected by ASD commonly lack the ability to extrapolate someone's goal by observing their actions alone. Similarly, they may lack the ability to estimate a partner's desired movement from observing haptics forces alone, thus the interpersonal goal integration mechanism may shed light on the specific differences between people with ASD and healthy individuals.

Molecular profiling of bark beetle mycobiota
Creators: name: Miller, Kirsten Eleanor
Publisher: name: Imperial College London
Year: 2015

description: No organism evolves in isolation; the symbiotic microorganisms associated with insects are key determinants of their hosts ecology and evolution. This thesis investigates the fungal communities found with bark and ambrosia beetles (Curculionidae: Scolytinae & Platypodinae) in an attempt to better understand the diversity and variability of this ecologically and economically important system. I start by assessing the efficacy of high throughput sequencing (HTS) and metabarcoding for the characterisation of fungal communities derived from whole arthropod DNA extracts (Chapter 2). I then apply this approach to understanding the biotic and abiotic determinants of beetle associated fungal taxa, and find that both beetle species identity and environmental conditions significantly predict community richness and composition (Chapter 3). In Chapter 4, I expand upon the beetle species level differences in microbial communities to show that they are driven by a relatively small subset of fungal taxa, predominantly belonging to the beetle associated Microascales, but also to the relatively unexplored Saccharomycetes. I further apply HTS to the recreation of beetle evolutionary histories using mitochondrial genomics, and test for correlations between beetle phylogenetic and mycobiotic similarities (Chapter 5). My investigations demonstrate the utility of recently developed sequencing technologies to the study of microbial symbioses and I conclude with a synthetic summary of my findings with suggestions for further research.
The Axl receptor tyrosine kinase is a discriminator of macrophage function in the inflamed lung

description: Much of the biology surrounding macrophage functional specificity has arisen through examining them during inflammation. However, tissue-specific triggers influence macrophage phenotype and function in health. The TAM family of receptor protein tyrosine kinases mediates the non-inflammatory removal of apoptotic cells by phagocytes through the bridging phosphatidylserine-binding molecules Gas6 or Protein S. We show that one such TAM receptor (Axl) is exclusively expressed on mouse airway macrophages, but not interstitial macrophages and other lung leukocytes, under homeostatic conditions and is constitutively ligated to Gas6. Axl expression is potently induced by GM-CSF expressed in the healthy and inflamed airway, and by type I interferon or TLR3 stimulation on human and mouse macrophages, indicating potential involvement of Axl in apoptotic cell removal under inflammatory conditions. Indeed, an absence of Axl does not cause sterile inflammation in health, but leads to exaggerated lung inflammatory disease upon influenza infection. The exacerbation of influenza infection was not due to inability to clear the viruses in Axl-/- mice, but was associated with enhanced weight loss, increased airway cellular infiltrates, and elevated nucleosome release indicative of secondary necrosis. These data imply that Axl allows specific identification of airway macrophages, and that its expression is critical for macrophage functional compartmentalisation in the airspaces or lung interstitium. We propose that this may be a critical feature to prevent excessive inflammation due to secondary necrosis of unefferocytosed apoptotic cells following inflammation.

title: Seafloor massive sulfide deposits from the Juan de Fuca Ridge: evidence from multiple sulfur isotopes for buried sediment and microbial activity.
Creators: name: Moriarty, Sarah
Publisher: name: Memorial University of Newofundland
Year: 2020

description: Submarine hydrothermal vent systems hosted at sedimented mid-ocean ridges are often associated with larger seafloor massive sulfide deposits than typical sediment-free mid-ocean ridge systems. The Juan de Fuca spreading ridge contains both sediment-hosted and sediment-free hydrothermal systems (Middle Valley and Axial Volcano, respectively). The ridge also contains the Endeavour vent field, which occurs at the outer extent of turbiditic sediments, where the seafloor is currently sediment-free and consists of basaltic lava flows, but evidence from hydrothermal vent fluid composition suggests the presence of buried sediment. Multiple sulfur isotope ratios of hydrothermal precipitates from these three sites were analyzed to isotopically fingerprint differences in hydrothermal sulfur cycling associated with sedimented and sediment-free substrates. A three-component mixing model in Δ³³S and δ³⁴S space was developed that represents the differing contributions of sulfur derived from seawater, magmatic sources, and both sediment and crustal sulfur sources that have been influenced by microbial activity.
