description: We study the effects of finite proton mass on the energy levels of hydrogen atoms moving transverse to a superstrong magnetic field $B$ with generalized pseudomomentum $K_\perp$. Field strengths of order $B\sim 10^{12}$ Gauss are typically found on the surfaces of neutron stars, but we also study the regime $B\go B_{crit}= 4.23\times 10^{13}$ Gauss, where the Landau excitation energy of the proton is large. We adopt two different approaches to the two-body problem in strong magnetic field, and obtain an approximate, but complete solution of the atomic energy as a function of $B$ and $K_\perp$. We show that, for $B>>B_{crit}$, there is an orthogonal set of bound states, which do not have any Landau excitation contribution in their energies. The states with very large $K_\perp$ have small binding energy and small transverse velocity, but are nevertheless distinct from the fully ionized states. The final results for the excitation energies are given in the form of analytical fitting formulae. The generalized Saha equation for the ionization-recombination equilibrium of hydrogen gas in the presence of a superstrong magnetic field is then derived. Although the maximum transverse velocity of a bound atom decreases as $B$ increases, the statistical weight due to transverse motion is actually increased by the strong magnetic field. For astrophysically interesting case of relatively low density and temperature, we obtain analytic approximations for the partition functions. The highly excited bound states have a smaller statistical weight than the fully ionized component.

description: Previous mRNA transcriptome studies of Euglena gracilis have shown that this organism possesses a large and diverse complement of protein coding genes; however, the study of non-coding RNA classes has been limited. The natural extensive fragmentation of the E. gracilis large subunit ribosomal RNA presents additional barriers to the identification of non-coding RNAs as size-selected small RNA libraries will be dominated by rRNA sequences. In this study we have developed a strategy to significantly reduce rRNA amplification prior to RNA-Seq analysis thereby producing a ncRNA library allowing for the identification of many new E. gracilis small RNAs. Library analysis reveals 113 unique new small nucleolar (sno) RNAs and a large collection of snoRNA isoforms, as well as the first significant collection of nuclear tRNAs in this organism. A 3′ end AGAUGN consensus motif and conserved structural features can now be defined for E. gracilis pseudouridine guide RNAs. snoRNAs of both classes were identified that target modification of the 3′ extremities of rRNAs utilizing predicted base-pairing interactions with internally transcribed spacers (ITS), providing insight into the timing of steps in rRNA maturation. Cumulatively, this represents the most comprehensive analysis of small ncRNAs in Euglena gracilis to date.

description: USAID’s Integrated Pest Management (IPM) Innovation Lab has been involved in the surveillance and environmentally-friendly management of recent invasions of exotic pests, including the weed parthenium (Parthenium hysterophorus), and insect pests such as papaya mealybug (Paracoccus marginatus), South America tomato leafminer (Tuta absoluta), and fall armyworm (Spodoptera frugiperda). To suppress parthenium in Ethiopia, we introduced and mass-reared two natural enemies – Zygogramma bicolorata and Listronotus setosipennis. For papaya mealybug control in India, we assisted in the introduction and mass release of a parasitoid from Mexico, Acerophagus papaya. We have surveilled the global spread of the South American tomato leafminer and have implemented control technologies such as pheromone traps and bio-rational pesticides. For fall armyworm control in Africa and Asia, we are developing methodology to rear and release local egg parasitoids, Trichogramma spp. and Telenomus remus.

Near-Infrared Imaging of Early-Type Galaxies IV. The Physical Origins of the Fundamental Plane Scaling Relations

description: The physical origins of the Fundamental Plane (FP) scaling relations are investigated for early-type galaxies observed at optical and near-infrared wavelengths. The slope for the FP is shown to increase systematically with wavelength from the U-band through the K-band. A distance-independent construction of the observables is described which provides an accurate measurement of the change in the FP slope between any pair of bandpasses. The variation of the FP slope with wavelength is strong evidence of systematic variations in stellar content along the elliptical galaxy sequence. The intercept of the diagnostic relationship between log(D_K/D_V) and log(sigma_0) shows no significant dependence on environment within the uncertainties of the Galactic extinction corrections, demonstrating the universality of the stellar populations contributions at the level of Delta(V-K)=0.03 mag to the zero-point of the global scaling relations. Several other constraints on the properties of early-type galaxies --- the slope of the Mg_2-sigma_0 relation, the effects of stellar populations gradients, and deviations of early-type galaxies from a dynamically homologous family --- are included to construct an empirical, self-consistent model which provides a complete picture of the underlying physical properties which are varying along the early-type galaxy sequence. This empirical approach demonstrates that there are significant systematic variations in both age and metallicity along the elliptical galaxy sequence, and that a small, but systematic, breaking of dynamical homology (or a similar, wavelength independent effect) is required. Predictions for the evolution of the slope of the FP with redshift are described. [abriged]

The innate immune rheostat : miRNA and negative regulation pathways which determine susceptibility to secondary bacterial complication
Creators: name: Godlee, Alexandra Elisabeth Clare
Publisher: name: Imperial College London
Year: 2012

description: Analysis of post-mortem specimens from the 1918 influenza pandemic showed that although many people were infected with this virus, of those that died the vast majority had a secondary bacterial pneumonia. Such complications are now recognised as a dangerous consequence of many inflammatory lung diseases. The innate immune rheostat determines the responsiveness of the immune system to infection. We aim to map the signalling pathways which influence the rheostat in the lung at homeostasis; and how prior infection with Respiratory Syncytial Virus or Influenza virus alters this to cause secondary bacterial pneumonia and sepsis. Our central hypothesis is that prior inflammation in the lung alters subsequent innate responsiveness by modulating specific immune regulatory pathways, and that the extent of this change is dictated by the severity of the first inflammatory insult. We show that susceptibility to bacterial complication extends far beyond the period of acute viral disease in all viral models studied. Concentrating on alveolar macrophage, the front line of defence in the lung, we observe that viral infection leads to Toll-like receptor desensitisation, an increase in the expression of innate negative regulators, and a dramatic change in the microRNA profile of these cells. Similar alterations in the microRNA profile of alveolar macrophage were observed following a variety of inflammatory insults, suggesting this represents a universal phenomenon. By manipulating these microRNAs it seems possible to reset the threshold of activation of alveolar macrophage, suggesting that these small molecules may be viable therapeutic targets.

The use of kisspeptin as a novel physiological oocyte maturation trigger for patients undergoing IVF treatment
Creators: name: Christopoulos, Georgios
Publisher: name: Imperial College London
Year: 2015

description: Background: Patients with inactivating mutations in kisspeptin signalling are infertile. Kisspeptin-54, the major circulating isoform of kisspeptin in humans, potently stimulates reproductive hormone secretion in humans. Animal studies suggest that kisspeptin is involved in the generation of the luteinising hormone surge, which is required for ovulation. I hypothesised that kisspeptin-54 could be a novel method used to trigger egg maturation in women undergoing in vitro fertilisation therapy. Methods: This was a proof of concept study. Following superovulation with follicle stimulating hormone, and gonadotrophin releasing hormone antagonist administration to prevent premature ovulation, 53 women were administered a single subcutaneous injection of kisspeptin-54 (1.6nmol/kg, n=2; 3.2nmol/kg, n=3; 6.4nmol/kg, n=24; 12.8nmol/kg, n=24) to induce a luteinising hormone surge and egg maturation. Eggs were retrieved transvaginally 36h after kisspeptin injection, assessed for maturation (primary outcome), and fertilised by intracytoplasmic sperm injection with subsequent transfer of one or two embryos. Results: Overall, egg maturation was observed in 96% (51/53) of patients. Fertilisation of eggs and transfer of embryos to the uterus occurred in 92% (49/53) of patients. Biochemical and clinical pregnancy rates were 40% (21/53) and 23% (12/53), respectively. Conclusion: This study demonstrates that a single injection of kisspeptin-54 can induce high rates of egg maturation in women with sub-fertility undergoing in vitro fertilisation therapy. Subsequent fertilisation of eggs matured following kisspeptin-54 administration and transfer of resulting embryos can lead to successful human pregnancy.

description: Circulating microRNAs (miRNAs) are considered as reliable candidates for biomarker discovery. RNA-Sequencing has become the most suitable technique to accurately quantify the miRNAome. However, RNA-Sequencing relies on several technical passages before reaching the final-end. HTG EdgeSeq technology, thanks to the abrogation of RNA extraction step, allows productivity enhancement by reducing the number of hands-on steps, the time for sample preparation and, therefore, the costs. We found a strong correlation between qPCR and dPCR with HTG (Pearson’s coefficient of 0.93 and 0.94, respectively). In conclusion, we showed that HTG EdgeSeq, performed on human plasma specimens without RNA extraction, is reliable, allows the simultaneous screening of more than 2,000 miRNAs, and thus, it could be applied to biomarker discovery in large cohorts.

description: Observations have revealed that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, these SMBHs form SMBH binaries (SMBHBs) that emit low-frequency gravitational waves (GWs). The incoherent superposition of these sources produce a stochastic GW background (GWB) that can be observed by pulsar timing arrays (PTAs). The optimal statistic is a frequentist estimator of the amplitude of the GWB that specifically looks for the spatial correlations between pulsars induced by the GWB. In this paper, we introduce an improved method for computing the optimal statistic that marginalizes over the red noise in individual pulsars. We use simulations to demonstrate that this method more accurately determines the strength of the GWB, and we use the noise-marginalized optimal statistic to compare the significance of monopole, dipole, and Hellings-Downs (HD) spatial correlations and perform sky scrambles.

Aeroelastic modelling and control of very flexible air vehicles using a nonlinear modal formulation
Creators: name: Wang, Yinan
Publisher: name: Imperial College London
Year: 2015

description: We present the development of a nonlinear reduced-order formulation for the simulation of geometrically-nonlinear responses of flexible aircraft and other aeroelastic systems. The theoretical foundation of the formulation will be presented first, based on a modal projection of the intrinsic description for beams, coupled with a 2-D unsteady aerodynamic description. We will then investigate the preservation of conservation laws in the proposed method and develop the numerical details in a practical implementation of the method in MATLAB. In this work we also developed a method of obtaining coeffcients of the nonlinear modal beam equations by means of a condensation process, based on the direct application of Guyan reduction of a high-fidelity 3D FE model. Structural and aeroelastic simulations will be presented to verify the implementation of the method against theory and published results, as well as demonstrating the numerical properties of the approach. Static trim, stability analysis and open-loop nonlinear flight simulations using the framework will be demonstrated on a highly-flexible flying wing and compared with published results, as well as carrying out control design and closed-loop nonlinear simulations to demonstrate the capabilities of the proposed reduced-order method.

description: The relativistically broad X-ray iron line seen in many AGN spectra is thought to originate from the central regions of the putative black hole accretion disk. Both the line profile and strength will vary in response to rapid variability of the primary X-ray continuum source. The temporal response of the line contains information on the accretion disk structure, the X-ray source geometry, and the spin of the black hole. Since the X-ray source will have a size comparable to the fluorescing region of the accretion disk, the general reverberation problem is not invertible. However, progress can be made since, empirically, AGN light curves are seen to undergo dramatic short timescale variability which presumably corresponds to the creation of a single new active region within the distributed X-ray source. The iron line response to these individual events can be described using linear transfer theory. We consider the line response to the activation/flaring of a new X-ray emitting region. Most of our detailed calculations are performed for the case of an X-ray source on the symmetry axis and at some height above the disk plane around a Kerr black hole. We also present preliminary calculations for off-axis flares. We suggest ways in which future, high-throughput X-ray observatories such as XMM and the Constellation X-ray Mission may use these reverberation signatures to probe both the mass and spin of AGN black holes, as well as the X-ray source geometry.

description: A non-linear equation obtained by adding gravitational self-interaction terms to the Poisson equation for Newtonian gravity is here employed in order to analyse a static spherically sym- metric homogeneous compact source of given proper mass and radius and the outer vacuum. The main feature of this picture is that, although the freedom of shifting the potential by an ar- bitrary constant is of course lost, the solutions remain qualitatively very close to the Newtonian behaviour. We also notice that the negative gravitational potential energy is smaller than the proper mass for sources with small compactness, but for sources that should form black holes according to General Relativity, the gravitational potential energy becomes of the same order of magnitude of the proper mass, or even larger. Moreover, the pressure overcomes the energy density for large values of the compactness, but it remains finite for finite compactness, hence there exists no Buchdahl limit. This classical description is meant to serve as the starting point for investigating quantum features of (near) black hole configurations within the corpuscular picture of gravity in future developments.

Hydrogen Molecules In Superstrong Magnetic Field: II. Excitation Levels

description: We study the energy levels of H$_2$ molecules in a superstrong magnetic field ($B\go 10^{12}$ G), typically found on the surfaces of neutron stars. The interatomic interaction potentials are calculated by a Hartree-Fock method with multi-configurations assuming electrons are in the ground Landau state. Both the aligned configurations and arbitrary orientations of the molecular axis with respect to the magnetic field axis are considered. Different types of molecular excitations are then studied: electronic excitations, aligned (along the magnetic axis) vibrational excitations, transverse vibrational excitations (a constrained rotation of the molecular axis around the magnetic field line). Similar results for the molecular ion H$_2^+$ are also obtained and compared with previous variational calculations. Both numerical results and analytical fitting formulae are given for a wide range of field strengths. In contrast to the zero-field case, it is found that the transverse vibrational excitation energies can be larger than the aligned vibration excitation, and they both can be comparable or larger than the electronic excitations. For $B\go B_{crit}=4.23\times 10^{13}$ G, the Landau energy of proton is appreciable and there is some controversy regarding the dissociation energy of H$_2$. We show that H$_2$ is bound even for $B>>B_{crit}$ and that neither proton has a Landau excitation in the ground molecular state.

Characterization of response properties in the mouse lateral geniculate nucleus
Creators: name: Tang, Jiaying
Publisher: name: Imperial College London
Year: 2015

description: The lateral geniculate nucleus (LGN) has been increasingly recognized to actively regulate information transmission to primary visual cortex (V1). Although efforts have been devoted to study its morphological and functional features, the full array of response characteristics in mouse LGN as well as their dependency on subjective state have been relatively unexplored. To address the question we recorded from mouse LGN with multisite-electrode-arrays (MEAs). From a dataset with 185 single units, our results revealed several exceptional response features in mouse LGN. We also demonstrated that subtypes, such as ON-/OFF-centre and transient/sustained cells exhibited functionally distinctive features, which might indicate parallel projections. To further compare response features from the full extent of mouse LGN, we developed a three-dimension (3D) LGN volume through histological approach. This volume explicitly captures morphological features of mouse LGN and provides the preciseness to classify location of single neuron into the anterior/middle/posterior LGN. Based on this categorization, we showed that response features were not regionally restricted within mouse LGN. We further examined neural activity with subjects in high or low isoflurane states. The distinct features in LFPs between the two states indicated that adjusting isoflurane concentration could provide a reliable and controllable experimental model to explore the state-dependent neural activity in mouse visual system. Subsequently, our results demonstrated that properties, including response latency, contrast sensitivity and spatial frequency properties were modulated by isoflurane concentration. Our current work suggests that mouse LGN can dynamically regulate information transmission to the cortex using numerous mechanisms, including responding mode, modulation of neuronal responses according to subjects’ states.

description: We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4-0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617-5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 kyr, the sixth smallest of all known pulsars. The unusual apparent youth of the pulsar and its proximity to a young remnant requires that an association be considered. Although the respective ages and distances are consistent within substantial uncertainties, the large inferred pulsar transverse velocity is difficult to explain given the observed pulsar velocity distribution, the absence of evidence for a pulsar wind nebula, and the symmetry of the remnant. Rather, we argue that the objects are likely superposed on the sky; this is reasonable given the complex area. Without an association, the question of where is the supernova remnant left behind following the birth of PSR J1617-5055 remains open. We also discuss a possible association between PSR J1617-5055 and the gamma-ray source 2CG 333+01. Though an association is energetically plausible, it is unlikely given that EGRET did not detect 2CG 333+01.

description: Quantum state diffusion (QSD) as a tool to solve quantum-optical master equations by stochastic simulation can be made several orders of magnitude more efficient if states in Hilbert space are represented in a moving basis of excited coherent states. The large savings in computer memory and time are due to the localization property of the QSD equation. We show how the method can be used to compute spectra and give an application to second harmonic generation.

description: Les étudiants de 2ème année des deux filières « Géologie » et « Geophysique » du Master de l'Université Côte d'Azur suivent l'intégralité du module « Geosciences Marines » qui gravite autour du stage embarqué. Ce module se décompose ainsi :
- Introduction Thématique : Structuration tectonique et évolution sédimentaire de la marge N. Ligure. (Cours Magistral 3h)
- Introduction Méthodologique : théorie de l'acquisition de données de sismique réflexion (Cours Magistral 3h)
- Embarquement : Acquisition d'une ou plusieurs lignes sismiques (24h en mer, TD :8h)
- Traitement de données sismiques superficielles avec Seismic Unix (6h)
- Traitement de données de sismique profonde avec Geovation (20h)
- Interprétation des images sismiques obtenues (6h)
- Rédaction d'un rapport présentant l'intégralité des apprentissages de la théorie de la méthode à l'interprétation des résultats dans le contexte Géologique Régional (Travail personnel).Au cours du stage, les sorties en mer permettent d'acquérir deux à trois grands profils sismiques. Ces données, une fois traitées avec Seismic Unix et interprétées, permettent de carter les structures tectoniques de la marge et les édifices sédimentaires sur les premiers kilomètres du sous-sol. Ce traitement destiné à imager les structures superficielles se double d'un apprentissage du logiciel de traitement Geovation qui a pour but d'imager les structures profondes de la marge sur la base d'un profil 720-traces acquis sur le "Pourquoi Pas?" au cous de la Campagne Sefassil. L'ensemble de la séquence pédagogique détaillée ci-dessus est donc mis en ?uvre concrètement au cours du stage. Ce module marin associés aux sorties de terrain à terre permettent aux étudiants d'aborder quelques problèmes géologiques particulièrement démonstratifs sur la marge continentale nord-ligure, tels que le rifting Oligo-Miocène, la crise de salinité Messinienne et le bassin profond de la mer Ligure.Cette formation est très valorisante pour les étudiants car :
- Elle leur permet de réaliser un véritable travail de recherche qui aboutit à l'écriture d'un rapport complet (voir un exemple en annexe). L'accent est tout particulièrement mis sur la démarche scientifique consistant à assimiler l'état de l'art du contexte géodynamique et tectonique de la zone et à mettre en évidence les apports que les acquisitions réalisées fournissent à cet état de l'art.
- Elle fournit un contenu méthodologique fort qui leur permet d'être ensuite autonome sur deux logiciels fondamentaux du traitement de l'imagerie sismique, dont Géovation®, logiciel développé par la CGG et qui équipe grand nombre des instituts académiques et groupes privés nationaux et internationaux travaillant dans le domaine de la prospection géophysique marine.
- Enfin, d'un point de vue Thématique, l'accent est mis dans le cadre du Master, sur l'aspect Terre-Mer des structures et caractéristiques tectoniques. Les étudiants recherchent sur ces données sismiques la continuité de ce qu'ils observent également à terre.

description: The synthesis of dimensionally stable carbon-based chemically modified electrodes (CMEs) is a challenge. The synthesis method, the electrode composition, and the heating used influences various properties of the electrodes. Here, we show an innovative, low cost, and efficient heating method for the CMEs production. We deposited ternary ruthenium, antimony, and tantalum or bismuth oxides on carbon-felts by the Pechini method focusing on the influence of different heating methods (conventional and microwave) on their electrochemical and physical properties. The oxides synthesized using microwave heating coated completely the carbon-felts fibers, displaying homogeneous morphology, while maintaining their three-dimensional character. XRD and XRF analyses confirm the presence of the desired oxides on the coating surfaces and the experimental metal load values close to the nominal (87–91% for Ru, 3–6% for Sb, and 4–7% for Ta or Bi, respectively). The microwave-assisted method yields CMEs with electrochemical active areas 136-fold (for tantalum-based) and 153-fold (for bismuth-based) higher than the unmodified carbon felt. The service lifetime of the CMEs is almost twice as high when using microwave heating than when using conventional heating, which is attributed to the complete and homogeneous coating of the fibers obtained using this heating method. In contrast, the conventional heating led to the incomplete covering of the fibers and to CMEs with low stability. Therefore, the use of microwave heating for the CMEs synthesis reduces the production time at around 60%, thus decreasing the production costs and producing CMEs with improved quality and stability when compared to both conventional-made CMEs and unmodified electrodes.
Fermi surface pockets in electron-doped iron superconductor by Lifshitz transition

description: The Fermi surface pockets that lie at the corner of the two-iron Brillouin zone in heavily electron-doped iron selenide superconductors are accounted for by an extended Hubbard model over the square lattice of iron atoms that includes the principal 3d xz and 3d yz orbitals. At half filling, and in the absence of intra-orbital next-nearest neighbor hopping, perfect nesting between electron-type and hole-type Fermi surfaces at the the center and at the corner of the one-iron Brillouin zone is revealed. It results in hidden magnetic order in the presence of magnetic frustration within mean field theory. An Eliashberg-type calculation that includes spin-fluctuation exchange finds that the Fermi surfaces undergo a Lifshitz transition to electron/hole Fermi surface pockets centered at the corner of the two-iron Brillouin zone as on-site repulsion grows strong. In agreement with angle-resolved photoemission spectroscopy on iron selenide high-temperature superconductors, only the two electron-type Fermi surface pockets remain after a rigid shift in energy of the renormalized band structure by strong enough electron doping. At the limit of strong on-site repulsion, a spin-wave analysis of the hidden-magnetic-order state finds a "floating ring" of low-energy spin excitations centered at the checkerboard wavenumber (pi,pi). This prediction compares favorably with recent observations of low-energy spin resonances around (pi,pi) in intercalated iron selenide by inelastic neutron scattering.

ISOCAM Molecular Hydrogen Images of the Cep E Outflow

description: The physical characteristics of Cepheus E (Cep E) `embedded' outflow are analyzed using ISOCAM images in the v=0-0 S(5) 6.91 um and S(3) 9.66 um molecular hydrogen lines. We find that the morphology of the Cep E outflow in the ground vibrational H2 lines is similar to that of the near infrared v=1-0 2.12 um line. At these mid-IR wavelengths, we do not detect the second H2 outflow which is almost perpendicular to Cep E 2.121 um flow or traces of H2 emission along the second 12CO J = 2-1 outflow at 52 degrees angle, down to a surface brightness of 12 - 46 uJy/arcsec square. We do detect at 6.91 um the likely source of the main H2 and CO outflows, IRAS 23011+6126, and show that the source is easily seen in all IRAS bands using HiRes images. The source is not detected at 9.66 um, but we think this agrees with the interstellar extinction curve which has a minimum at 7 um, but rises a 9.7 um due to the strong absorption silicate feature, enhanced in this case by a cocoon surrounding the Class 0 object. This idea is supported by our models of the spectral energy distribution (SED) of the central object. The models assume that the main source of opacity is due to bare silicates and our best fit for the SED yields a total mass of envelope of 17 solar masses and a dust temperature of 18 K.
