Automated BioPart characterisation for synthetic biology
Creators: name: Hirst, Christopher David
Publisher: name: Imperial College London
Year: 2014

description: Synthetic Biology is an approach to the development of biological systems based on engineering principles. By using concepts from other engineering disciplines such as abstraction it is possible to break down complicated biological functions into components termed ‘BioParts’. BioParts can be assembled collectively into modules and systems to carry out advanced functions, designed from the bottom up. A key part of this approach is the standardisation of BioParts and practices to aid design, testing and implementation. An automated characterisation methodology focused primarily on promoter BioParts has been developed which is potentially scalable to other BioPart families. The standardised workflow is optimised to enable BioPart characterisation under highly reproducible growth conditions, reliably producing high quality data. It has been designed around automation equipment which should ensure accurate reproduction of experiments at other sites. The automated characterisation workflow has been demonstrated to produce high quality data for both constitutive and inducible promoters. The entire Anderson promoter collection has been characterised and high details results for all library members are available for the first time. A pair of inducible promoter BioPart were characterised to obtain a deep data level regarding their activity in response to inducer over time. To allow the characterisation of more inducible BioParts in a shorter period of time, promoter engineering was also used to generate novel promoters which are induced by xylose. The development of the automated workflow should be a step towards the standardisation of characterisation protocols and production of large numbers of BioParts with associated high quality, reproducible characterisations. Standardisation will further aid the comparison of the data sets produced, potentially shining light on unknown interactions between BioParts and their environment and improving the ability of Synthetic Biologists to design novel biological systems from the ground up.

Modelling of turbulent wakes
Creators: name: Rigas, Georgios
Publisher: name: Imperial College London
Year: 2014

description: The dynamics of the turbulent three-dimensional wake generated by an axisymmetric bluff body with blunt trailing edge are experimentally and theoretically investigated at a diameter based Reynolds number of 188,000. A detailed analysis of the base pressure measurements shows that the large scale structures of the turbulent three-dimensional wake retain the structure of the laminar instabilities observed in the transitional regimes, in a statistical sense. These persisting instabilities at the turbulent regime, are associated with spatial and temporal symmetry breaking, giving rise to spatial reflectional symmetry and quasi-periodic vortex shedding. The influence of turbulence recovers the lost temporal and spatial symmetries in the long-time average. It is shown that the turbulent spatial dynamics are reproduced by a simple stochastic model the deterministic part of which accounts for the spatial symmetry breaking and gives rise to steady large scale structures through a supercritical pitchfork bifurcation, and the stochastic part modelling in a phenomenological sense the turbulent fluctuations acting on the large scale structures. The axisymmetric body wake is further investigated when axisymmetric slot-jet zero-net-mass-flux forcing is applied on the rear base. Landau-like models that capture the weakly nonlinear interaction between the global vortex shedding mode and axisymmetric forcing are derived from the phase-averaged Navier-Stokes equations. The Landau-like models describe accurately the forced response by means of measured base pressure of the global vortex shedding mode. With the present analysis it is demonstrated that the concept of weakly nonlinear global modes can be extended to a fully turbulent flow, far from the critical bifurcation Reynolds number, and a general framework for the description of systems with broken symmetries---giving rise to global dynamics---and turbulent dynamics is provided. The novel results presented here advance the understanding of the dynamics of three-dimensional turbulent wakes and pave the way for turbulence prediction and control.

description: We study the field theory for the SU($N_c$) symmetric antiferromagnetic quantum critical metal with a one-dimensional Fermi surface embedded in general space dimensions between two and three. The asymptotically exact solution valid in this dimensional range provides an interpolation between the perturbative solution obtained from the $ε$-expansion near three dimensions and the nonperturbative solution in two dimensions. We show that critical exponents are smooth functions of the space dimension. However, physical observables exhibit subtle crossovers that make it hard to access subleading scaling behaviors in two dimensions from the low-energy solution obtained above two dimensions. These crossovers give rise to noncommutativities, where the low-energy limit does not commute with the limits in which the physical dimensions are approached.

description: La biogéographie des espèces ectothermes de l'océan Austral est déterminée en partie par la température comme semble l'attester la distribution spatiale des espèces en fonction du gradient thermique latitudinal. Les campagnes REPCCOAI proposent (1) de poursuivre l'échantillonnage en continu du mésozooplancton par un Continuous Plankton Recorder et (2) l'échantillonnage à quelques stations du macrozooplancton (principalement les euphausiacés) et des poissons mésopélagiques avec un Isaacs Kidd Midwater Trawl, petit chalut pélagique. Ces campagnes, couplées aux campagnes OISO en océanographie et THEMISTO en acoustique, permettront d'étudier la distribution spatiale de la diversité pélagique de la zone subtropicale à la zone antarctique de la partie indienne de l'océan Austral. Les modèles actuels prédisent que les zones subantarctiques et subtropicales se décaleront plus au sud en raison du réchauffement climatique en limitant la zone antarctique au Sud du front polaire antarctique. C'est au niveau de ces zones de transition que s'observent les plus forts gradients biogéographiques et d'abondance du plancton et des poissons mésopélagiques, proies de nombreuses espèces d'oiseaux ou de mammifères marins. Un des objectifs de ces campagnes sera d'évaluer, par expérimentation, les capacités de résilience des différentes espèces ou populations de krill confrontées à des élévations de température du milieu marin. Cela consiste en l'étude des capacités de l'organisme à résister à un choc thermique mais aussi des mécanismes physiologiques associés. Il s'agit d'expliquer la distribution actuelle des espèces mais également de prédire comment le réchauffement global est susceptible d'impacter les espèces là où elles se trouvent et comment elles seront capables d'y faire face.

description: In this paper, we investigate cross-lingual learning (CLL) for multilingual scene text recognition (STR). CLL transfers knowledge from one language to another. We aim to find the condition that exploits knowledge from high-resource languages for improving performance in low-resource languages. To do so, we first examine if two general insights about CLL discussed in previous works are applied to multilingual STR: (1) Joint learning with high- and low-resource languages may reduce performance on low-resource languages, and (2) CLL works best between typologically similar languages. Through extensive experiments, we show that two general insights may not be applied to multilingual STR. After that, we show that the crucial condition for CLL is the dataset size of high-resource languages regardless of the kind of high-resource languages. Our code, data, and models are available at https://github.com/ku21fan/CLL-STR.

The application of novel imaging modalities in the monitoring of inflammatory activity in Crohn’s disease
Creators: name: Russo, Evangelos Alessios
Publisher: name: Imperial College London
Year: 2015

description: Clinical scores, serum and faecal markers, and endoscopy all have limitations in their use as instruments to monitor disease activity in Crohn’s disease (CD). Recently, 18F-FDG-PET and novel MRI techniques have been proposed as sensitive and specific methods to quantify the inflammatory load. The aim of this work was to assess the reliability, responsiveness and, to an extent, the validity of outcome measures in these modalities, in monitoring inflammatory activity over a 12-week interval. In addition, two receptors, TSPO and IL-2R were assessed on tissue specimens ex-vivo for their potential to act as alternative targets for molecular imaging in CD. Three distinct groups of patients were recruited, 2 of which participated in the clinical imaging study, and one to donate tissue for the laboratory work. Dual timepoint FDG-PET and MRI scanning was performed within 1 week (Group 1) to assess the test-retest reliability of the imaging outcome measures, and before, and twelve weeks into anti-TNFα therapy (Group 2) to assess their responsiveness indices. The third group contributed tissue during scheduled intestinal resection for assessment of TSPO and IL-2R interactions with their corresponding radioligands. To support the latter study, stored tissue sections were also obtained for immunohistochemical assessment of target receptor expression. Results on 22 patients show that PET endpoints such as SUVMAX and SUVMEAN have high responsiveness and reliability indices and demonstrated significant differences in anti-TNF responders compared to non-responders. The finding of luminal FDG signal may affect the face validity of the scan. MRI modalities appeared less responsive at three months. Analysis on ex-vivo specimens showed increased abundance of TSPO in normal bowel, but a relative over-expression in inflamed specimens which was not statistically significant. IL-2R appeared more abundant in transmural sections containing severe CD, but autoradiographic corroboration was not achieved for technical reasons.

Although the new 3He(d,p)4He S-factors are significantly lower than those reported by Engstler et al. they clearly show the presence of electron screening effects. From the new S-factors we find an electron screening energy in agreement with the adiabatic limit.

description: Cable bacteria (Ca. Electrothrix) are long, filamentous, multicellular bacteria that grow in marine sediments and couple sulfur oxidation to oxygen reduction over centimeter-scale distances via an enigmatic long-distance electron transport mechanism. They can grow to tremendous densities and strongly modify the sediment environment in multiple ways, including efficient sulfide removal, stimulation of sulfate reduction, and alteration of porewater pH distribution. In this thesis, I asked if cable bacteria can influence the sympatric microbial community composition and activity, using a time-series manipulation experiment. As anticipated, based on their influence on sediment geochemistry, cable bacteria growth was associated with the stimulation of several genera of sulfate-reducing bacteria, and a sulfur-disproportionating genus (Desulfocapsa). I observed a positive relationship with the OM27 clade of the predatory Bdellovibrionota. Finally, I detected evidence of interaction with two chemoautotrophic sulfur oxidizers (Thiogranum, Sedimenticola), which are good candidates for further examination of potential electrical connection with cable bacteria.

Dispersing Crude Oils of Varying Viscosities Using a Food-Grade Dispersant

Subjects: subject: Chemical engineering

description: The mitigation of crude oil spills in the ocean is generally done using chemical dispersants, which convert the oil slick into small droplets. These dispersants are mixtures of surface-active molecules (surfactants) dissolved in a solvent. Questions regarding the toxicity of current commercial dispersants have prompted our lab to develop an eco-friendly alternative based on the food-grade surfactants, soy lecithin (L) and Tween 80 (T). In previous studies, the roles played by L/T and the solvent in a typical dispersant have been studied, but all those studies were done with a light crude oil, i.e., one with a low viscosity. In this thesis, we examine if our food-grade dispersant remains effective at dispersing heavier crude oils, i.e., crudes of higher viscosity. We study a light, a medium, and a heavy crude and compare their dispersion into seawater using a fixed L/T blend in various solvents. As expected, we find that the efficiency of dispersion is lower when the crude is more viscous. Moreover, in line with our previous findings, simply varying the solvent can alter the dispersion efficiency from poor to good. The solvents that promote dispersion can be identified systematically by using a plot of Hansen Solubility Parameters (HSPs). However, there do exist several key differences between the solvents most effective for the three crudes. Our analysis suggests that crude oil composition must be taken into account when optimizing the formulation of a dispersant.

The Formation of Giant Elliptical Galaxies and Their Globular Cluster Systems

description: The bimodal globular cluster (GC) metallicity distributions of many giant elliptical galaxies are often cited as evidence for the formation of such galaxies through mergers involving gas-rich spirals. In such models, the metal- rich GCs are assumed to have formed during the merger process. We explore an alternative possibility: that these metal-rich clusters represent the galaxy's intrinsic GC population and that the metal-poor component of the observed GC metallicity distribution arises from the capture of GCs from other galaxies, either through mergers or through tidal stripping. Starting with plausible assumptions for the initial galaxy luminosity function and for the dependence of GC metallicity on parent galaxy luminosity, we show that the growth of a pre-existing seed galaxy through mergers and tidal stripping is accompanied by the capture of metal-poor GCs whose properties are similar to those which are observed to surround giant ellipticals. We describe a method of using the observed number of metal-poor and metal-rich GCs to infer the merger histories of individual elliptical galaxies, and use this technique to derive limits on the number of galaxies and total luminosity accreted to date by M49. We argue that although GC specific frequency is conserved in galaxy mergers, the same may not be true of tidal stripping by the mean field of the host galaxy cluster. Comparisons of model GC metallicity distributions and specific frequencies to those observed for the well-studied galaxies M49 and M87 show that it is possible to explain their bimodal GC metallicity distributions and discordant specific frequencies without resorting to the formation of new GCs in mergers or by invoking multiple bursts of GC formation.

1) contribuer à l'évaluation annuelle du bilan de carbone global, en alimentant régulièrement les bases de données globales, notamment SOCAT et GLODAP;
2) mieux comprendre la variabilité du flux air-mer de CO2 dans l'Océan Indien Sud et Austral, dans le but d'isoler la perturbation anthropique, et ainsi évaluer l'évolution du puits de CO2 océanique (validation des modèles climatiques) et mieux comprendre le processus d'acidification des eaux qui en résulte;
3) documenter la variabilité des mécanismes physiques et biologiques qui influencent le cycle du CO2 dans l¿Océan Indien Sud et Austral;
4) fournir des observations in situ permettant de calibrer et valider les observations autonomes (e.g., données satellites, flotteurs Argo, BioArgo, CARIOCA, mammifères marins équipés de capteurs océanographiques);
5) documenter les changements environnementaux en lien avec la variabilité du climat et évaluer l'impact sur les organismes marins (coll., BIAF, MNHN, CEBC).
La campagne OISO28 avait pour but de poursuivre les observations dans les eaux de surface (en continu) et sur la colonne d'eau (18 stations) le long des trajets inter-iles et dans la zone Antarctique. L'exploration au sud de Crozet pour le programme REPCOAI a permis de renouveler les observations réalisées en janvier 2017 afin d'évaluer la variabilité interannuelle du CO2 dans les eaux Antarctiques de surface (mesures en continu) et en profondeur (station 37).Les projets de rattachement sont LEFE/CO2sink (G.

description: We consider a simplified model for resonant neutron-nucleus interaction with coupled channels. An analytical solution is given for two coupled channels and arbitrary neutron orbital momentum. A case of a week channel coupling, corresponding to narrow Breit-Wigner resonance, is analyzed in details. As far as the total width of a resonance coincides with the neutron width, the model is directly appropriate only for light nuclei. We study a mixing of two narrow s- and p-wave resonances by P- and P-,T-noninvariant potentials in the first order of perturbation theory. As an example a close-lying pair of s- and p-wave resonances of the $^{35}$Cl nucleus is considered. The favorable possibilities are shown to exist on thick targets for measurements beyond the resonance widths. In particular, an interference minimum near s-wave resonance is of interest for P-odd neutron spin rotation on light spinless nuclei.

Ab-initio modelling of Zr and Be alloys for nuclear applications
Creators: name: Burr, Patrick
Publisher: name: Imperial College London
Year: 2015

description: Zr and Be alloys are crucially important for a number of applications in extreme environments. Here, density functional theory simulations were carried out to investigate the effect of alloying additions and second phase particles (SPPs) on the physical, mechanical and corrosion properties of the alloys. First the partitioning of H between Zr SPPs and Zr metal is investigated. Zr(Cr,Fe)₂ is not expected to getter hydrogen from the Zr matrix but it may act as a bridge for locally enhanced H diffusion across the oxide barrier layer. On the other hand, Zr₂(Fe,Ni) may getter some H from Zr solution if the Fe/Ni ratio is low. Fe always decreases the H affinity of SPPs, whilst Nb increases H affinity of Laves phases and decreases that of β-(Zr,Nb) SPPs. Following irradiation induced SPP amorphisation, Fe and Cr dissolve and cluster in the Zr matrix. Both substitutional and interstitial accommodation are relevant to Fe and Cr additions and two new low-energy interstitial sites were identified. Local stress states affect the stability of point defects and, in turn, these cause highly anisotropic lattice strains in Zr-Fe and Zr-Cr solid solutions, which deviate from Vegard’s law. The solubility of Fe and Cr, which is remarkably limited in pristine Zr, is increased dramatically by pre-existing Zr vacancies. Strong binding was predicted for the clustering of V_Zr and Feᵢ/Crᵢ defects. Furthermore, up to four Fe or three Cr atoms may be accommodated on or around a single V_Zr, with lower solution energies and relaxation volumes than dilute solutions. Al and Fe are the most common impurities found in commercial Be alloys, yet the binary and ternary phases of the Be-Al-Fe system are poorly characterised. First, the Be-Fe phase diagram is considered and a new structure and composition were identified for the Be-rich ε phase. Phonon density of states calculations indicate that ε-Fe₂−xBe₁₇+x phase is only stable up to ∼ 1500 K, while δ-FeBe₅ is stable only above ∼ 1100 K and ζ-FeBe₂ is stable at all temperatures below melting. Non-stoichiometry, elastic and magnetic properties of the intermetallics were also evaluated. Small additions of Al stabilise the δ-FeBe₅ intermetallic over ε-Fe₂−xBe₁₇+x and ζ-FeBe₂. Increasing amounts of Al lead to the formation of a disordered (Al,Fe)Be₂ phase. Finally, the solubilities of selected extrinsic elements in Be metal and its SPPs were investigated. It was found that Si, Al, Li and H are preferentially dissolved in δ-FeBe₅, ζ-FeBe₂ and (Al,Fe)Be₂ over Be metal. The ability of Fe-bearing SPPs to absorb Al and Si is thought to be beneficial for the mechanical properties of Be alloys. On the other hand, if a sufficient volume fraction of SPPs is present, their high affinity for H may aggravate tritium retention in Be-based plasma facing components used in fusion reactors. SPPs were shown to not interact strongly with He. O, Mg and C preferentially form other SPPs (BeO, MgBe₁₃ and Be₂C respectively).

description: We report the first unambiguous detection of the host galaxy of a normal radio-quiet QSO at high-redshift in K-band. The luminosity of the host comprises about 35% of the total K-band luminosity. Assuming the average colour of QSOs at z=2, the host would be about 5 to 6 mag brighter than an unevolved L* galaxy placed at z=2, and 3 to 4 mag brighter than a passively evolved L* galaxy at the same redshift. The luminosity of the host galaxy of the QSO would thus overlap with the highest found in radio-loud QSOs and radio-galaxies at the same redshift.

description: We present a complete set of chemo-structural descriptors to significantly extend the applicability of machine-learning (ML) in material screening and mapping energy landscape for multicomponent systems. These new descriptors allow differentiating between structural prototypes, which is not possible using the commonly used chemical-only descriptors. Specifically, we demonstrate that the combination of pairwise radial, nearest neighbor, bond-angle, dihedral-angle and core-charge distributions plays an important role in predicting formation energies, bandgaps, static refractive indices, magnetic properties, and modulus of elasticity for three-dimensional (3D) materials as well as exfoliation energies of two-dimensional (2D) layered materials. The training data consists of 24549 bulk and 616 monolayer materials taken from JARVIS-DFT database. We obtained very accurate ML models using gradient boosting algorithm. Then we use the trained models to discover exfoliable 2D-layered materials satisfying specific property requirements. Additionally, we integrate our formation energy ML model with a genetic algorithm for structure search to verify if the ML model reproduces the DFT convex hull. This verification establishes a more stringent evaluation metric for the ML model than what commonly used in data sciences. Our learnt model is publicly available on the JARVIS-ML website (https://www.ctcms.nist.gov/jarvisml ) property predictions of generalized materials.
Enhancing gap junction coupling in reperfused myocardium
Creators: name: Debney, Michael Thomas
Publisher: name: Imperial College London
Year: 2015

description: The work in this thesis sought to examine the effects of enhancing cardiac gap junction coupling using the pharmacological agent Rotigaptide in clinically applicable models of acute myocardial infarction. Specifically, the studies in this thesis investigated the effect of Rotigaptide on ventricular arrhythmogenesis and structural remodelling of the reperfused substrate, with particular emphasis on the development, application and histological validation of diffusion tensor magnetic resonance imagine (DTI) as a novel imaging modality to describe and quantify structural remodelling post-infarction. An ex vivo rat model of acute regional ischaemia-reperfusion was characterised and used to study the effect of Rotigaptide on ventricular arrhythmogenesis during acute ischaemia and reperfusion. Arrhythmias occurred during ischaemia in a monomodal distribution with a peak incidence between 12-15 minutes after ischaemia. The incidence of reperfusion arrhythmias was dependent on the preceding duration of ischaemia with a progressive reduction as ischaemic time extended from 15 to 60 minutes. Rotigaptide pre-treatment afforded a significant reduction in ischaemia-induced arrhythmias compared to administration at the onset of ischaemia or at the time of reperfusion. An in vivo rat model of infarction-reperfusion, mimicking clinical reperfusion in the setting of acute MI was characterised and Rotigaptide administered prior to reperfusion and for a week post-MI. At four-weeks post-MI animals were studied with 6-lead ECG, ambulatory telemetry, programmed electrical simulation (PES), optical mapping, DTI and histology. Rotigaptide reduced the susceptibility to arrhythmias induced by PES and partially restored DTI-derived indices of tissue disruption in infarcted myocardium.
Isoscalar Roper Excitation in $p(α, α')$ Reactions in the $10 - 15$ $GeV$ Region

description: Recent experiments at Saturne at $4$ $GeV$ showed that the $(α,α')$ reaction on the proton shows two distinctive peaks, which were associated to $Δ$ projectile excitation and Roper target excitation. A subsequent theoretical analysis has shown that this picture is qualitatively correct but there are important interference effects between the two mechanisms. Futhermore, at this energy the ratio of strengths for the Roper and $Δ$ peak is about $1/4$. In the present paper we show that by going to the $10 - 15$ $GeV$ region the interference effects become negligible, the signal for the Roper excitation is increased by more than an order of magnitude and the ratio of cross sections at the peaks for Roper and $Δ$ excitation becomes of the order of unity, thus making this range of energies ideal for studies of isoscalar Roper excitation.

Surface reconstruction through microscopy data fusion
Creators: name: Yang, Shuo
Publisher: name: Imperial College London
Year: 2015

description: Reconstructing the surface microtopography through data fusion from a range of microscopies offers a way to provide considerably more information than any one technique alone. This thesis explores several methods for combining the info rmation from different kinds of microscopes including height data, electron images and optical images. Each microscopy has distinct advantages and disadvantages that can be considered in terms of data leakage in the transfer function from the actual sampl e topography to any individual dataset. These leakage paths are identified for a range of microscopies including atomic force microscopy, scanning electron microscopy and white light interferometry. Existing techniques for reconstruction from multiple image datasets, such as shape-from-shading and stereomicroscopy are evaluated, again in terms of information leakage. A new approach is presented which attempts to minimize leakage by identifying a pathway of data fusion which first isolates the most reliable information in each dataset, and then maintains this information as the datasets are combined. The identification of the most trusted data requires knowledge of each imaging mechanism, while the final reconstruction is based on iterative matching between the datasets and a simulated image. Hence the final reconstruction incorporates both the datasets from the microscopes and their imaging physics to suppress data leakage. This approach is first validated with a model micromachined sample using a combination of height interferometer data together with back-scattered and secondary scanning electron microscope images. It is then applied to particulate samples to demonstrate the capabilities of the approach.

description: La biogéographie des espèces ectothermes de l'océan Austral est déterminée en partie par la température comme semble l'attester la distribution spatiale des espèces en fonction du gradient thermique latitudinal.
La campagne REPCCOAI 2018 s'est proposée (1) de poursuivre l'échantillonnage en continu du mésozooplancton par un Continuous Plankton Recorder et (2) d'échantillonner à quelques stations du mésozooplancton par un WP2 et du macrozooplancton (principalement les euphausiacés) et des poissons mésopélagiques avec un Isaacs Kidd Midwater Trawl.
Cette deuxième campagne d'une série de quatre est couplée aux campagnes OISO en océanographie et THEMISTO en acoustique. Elle permettra d'étudier la distribution spatiale de la diversité pélagique de la zone subtropicale à la zone antarctique de la partie indienne de l'océan Austral.
Les modèles actuels prédisent que les zones subantarctiques et subtropicales se décaleront plus au sud en raison du réchauffement climatique en limitant la zone antarctique au Sud du front polaire antarctique. C'est au niveau de ces zones de transition que nous étudions que s'observent les plus forts gradients biogéographiques et d'abondance du plancton et des poissons mésopélagiques, proies de nombreuses espèces d'oiseaux ou de mammifères marins.Les projets de rattachement sont Southern Ocean Continous Plankton Recorder, Zone atelier Antarctique du CNRS et MESOPP (H2020).

Ly-alpha/H-alpha Ratio of Singly Ionized Helium in Quasars

description: He II Ly-alpha 304/H-alpha 1640 emission lines are mainly produced by recombination, and their canonical ratio of about 10 may be a sensitive reddening indicator. We obtain the high S/N optical spectra of two quasars and combine them with the far-UV spectra that show the He II 304 emission. For HS 1700+64, the He II 1640 emission is not detected, and an upper limit to it sets the ratio greater than 20. For Q0302-003, the ratio is very low, on the order of unity. The most plausible cause for such a low ratio is extinction in the EUV band by very fine grains of dust. Q0302-003 has a prominent narrow component of FWHM ~ 2000 km/s in its major emission lines, and it appears that reddening is associated only with the line-emitting region. We suggest that the geometry of the line-emitting region in high-z quasars resembles that in the low-luminosity active galaxies, with the presence of dust mostly in the outer part.

description: We consider, in general terms, the early thermal evolution of an isolated neutron star, i.e., during the first $10^5$ years after the supernova explosion when the cooling is driven by neutrino emission from the core. It is shown that, if fast neutrino emission is occuring, the surface temperature is actually determined by the critical temperature $T_c$ at which the core baryons become superfluid, and almost nothing else. In particular, the dependence on the actual neutrino emission process is very weak. In other terms, fast neutrino cooling neutron stars are thermometers for the highest $T_c$ superfluid (superconductor) in the Universe. The observational data are briefly presented.

description: HADOCC est un projet d'écoute acoustique passive à l'aide d'un hydrophone autonome au large de l'archipel de Crozet pour mieux comprendre la déprédation de la légine australe par les orques et les cachalots. Au cours de la mission MD211, cet hydrophone a été déployé dans la colonne d'eau à 75m de la surface sur une ligne de mouillage dans l'archipel de Crozet. Cet hydrophone collectera de façon autonome et passive les bruits du milieu marin (échantillonnés à 32 kHz) jusqu'à sa récupération, début
2019. L'analyse des enregistrements permettra d'évaluer la présence d'orques et de cachalots en dehors ou pendant des opérations de pêche (i.e. présence naturelle ou uniquement en saison de pêche) mais aussi d'autres espèces de cétacés dans la ZEE de Crozet.Le projet HADOCC (Hydrophone Autonome pour la compréhension de la Déprédation de la légine australe par les Orques et les Cachalots de Crozet) s'inscrit dans le programme ORCA DEPRED (resp. Christophe Guinet, CEBC) qui cherche à préciser le comportement de déprédation des orques et des cachalots par des approches différentes et complémentaires (acoustique passive court et long terme, lignes expérimentales de pêche, déploiement de balises).Levé bathymétrique multifaisceaux et site du mouillage HADOCC (triangle rouge)
