description: We have conducted a VLA search for radio pulsars at the positions of 44 nearby OB runaway stars. The observations involved both searching images for point sources of continuum emission and a time series analysis. Our mean flux sensitivity to pulsars slower than 50 ms was 0.2 mJy. No new pulsars were found in the survey. The size of the survey, combined with the high sensitivity of the observations, sets a significant constraint on the probability, $f_p$, of a runaway OB star having an observable pulsar companion. We find $f_p \le 6.5$\% with 95\% confidence, if the general pulsar luminosity function is applicable to OB star pulsar companions. If a pulsar beaming fraction of \onethird\ is assumed, then we estimate that fewer than 20\% of runaway OB stars have neutron star companions, unless pulsed radio emission is frequently obscured by the OB stellar wind. Our result is consistent with the dynamical (or cluster) ejection model for the formation of OB runaways. The supernova ejection model is not ruled out, but is constrained by these observations to allow only a small binary survival fraction, which may be accommodated if neutron stars acquire significant natal kicks. According to Leonard, Hills and Dewey (1994), a 20\% survival fraction corresponds to a 3-d kick velocity of 420 km s$^{-1}$. This value is in close agreement with recent revisions of the pulsar velocity distribution.

Controlled Nanoparticle Deposition Reveals High-Temperature Stability and Density-Independent Sintering of Pd/SiO2 Emissions Control Catalysts

description: Supported-metal emissions control catalysts must maintain steady activity at high temperatures over their entire lifetimes. However, preventing loss of reactive surface area due to particle sintering is challenging. It is thought that spatially isolating metal nanoparticles on the catalyst support slows high-temperature degradation by minimizing the probability of interparticle interaction. Yet, studying this effect is complicated by an inability to synthesize catalysts with well-defined nanoparticle spatial distributions using traditional synthesis methods. Herein, we prepare Pd/SiO​2 catalysts with quantifiable nanoparticle spatial distributions using colloidal Pd nanoparticles and amorphous spherical silica supports. With this model system, we demonstrate that Pd/SiO​2 sintering is thermally activated at 888°C and is independent of nanoparticle density on the support surface over two orders of magnitude. The vapor pressure of Pd and corresponding NP atomic solid-vapor exchange rate suggest a gas-phase sintering mechanism activated at the reduction temperature of PdO to metallic Pd. While minimal fusion of adjacent nanoparticles occurs at temperatures below 888 °C, the loss of reactive surface area is negligible. These results call into question the traditional approach of achieving maximum stability via spatial isolation of nanoparticles. Moreover, the remarkable stability of our system up to 888°C unlocks new strategies for the realization of sinter-resistant catalysts.
Physical layer network coding using lattice codes
Creators: name: Liu, William
Publisher: name: Imperial College London
Year: 2016

description: In this thesis, using lattice codes and channel codes, we propose several solutions to improve the performance of physical-layer network coding (PNC) schemes over the two-way relay network as well as the multi-way relay network. In the first part of our work, we propose an efficient equation-coefficient search algorithm for compute-and-forward over complex-valued channels, which guarantees to find the optimal coefficients over the ring of Gaussian integers as well as the ring of Eisenstein integers. We also propose an optimal coefficient search algorithm for the Integer-Forcing compute-and-forward receiver, when multiple receive antennas are available at the relay. The proposed algorithms are shown to have low polynomial complexity in transmitting user number and we use numerical results to verify the performance of our algorithms against other competitive search algorithms in literature. In the second part of our work we investigate the performance of popular PNC schemes for the two-way relay network and derive their end-to-end achievable rates with channel inversion precoding over the Rayleigh fading channel. We also propose a power efficient precoding scheme based on compute-and forward-to improve the network throughput. In the third part of our work, after introducing the novel concept of compatibility between channel code and lattice code, we propose several low complexity joint channel coded network coding (JCCNC) schemes for PAM and QAM two-way relay networks. Firstly, using LDPC codes, we propose the lattice-decoded JCCNC (LD-JCCNC) scheme. Secondly, we propose two JCCNC schemes using low density construction A (LDA) lattices and polar lattices, which we call LDA-JCCNC and PLA-JCCNC respectively. In both JCCNC schemes, channel coding and network coding operations are integrated through the use of lattice decoding at the relay, where the arithmetic addition of lattice codewords is directly decoded using their corresponding lattice decoding algorithm. In contrast with most existing JCCNC schemes which are restricted to set types of modulation schemes, we also give clear methodology on how our JCCNC schemes can be applied to general types of higher order PAM and QAM modulation schemes. In the final part of our work, we extend our novel JCCNC schemes to the general multi-way relay network for the compute-and-forward scheme, and show how they can be used with general types of PAM and QAM modulation systems. Detailed simulation analysis are carried out to evaluate and compare the performance of all proposed JCCNC schemes in relation to existing schemes in literature.

Thermodynamic assessments of the (Zr,Hf) carbides and borides revisited and informed by the calculation of defect formation energies in ZrC
Creators: name: Davey, Theresa
Publisher: name: Imperial College London
Year: 2017

description: Some transition metal carbides and borides are ultra-high temperature ceramic compounds that have application in the nuclear and aerospace industries. The existing thermodynamic assessments of the systems containing the hafnium and zirconium carbides and borides were examined, along with all available experimental and theoretical data. One of the challenges of thermodynamic modelling is in accurately describing the point defects in ordered compounds. In the transition metal carbides and borides, vacancies and substitutional defects are common and play a significant role in determining the material behaviour. Hafnium and zirconium are very difficult to separate, and as such there is always some level of contamination in these compounds. Despite this, there is very limited quantitative information available about the effect that this contamination has on the properties of the material. Using first principles calculations of substitutional point defects in UHTC compounds, the CALPHAD modelling in existing thermodynamic assessments of the ternary boron-hafnium-zirconium and carbon-hafnium-zirconium systems was considered and areas for improvement were identified using the first principles insights. Hafnium and zirconium carbide have a wide range of stoichiometry facilitated by carbon vacancies. Developments to first principles techniques have allowed calculations of properties such as the vacancy formation energy that should be considered in thermodynamic assessment, but are currently not explicitly considered in the modelling. Using the carbon-zirconium system as an example, a method was developed by which the vacancy formation energy and vacancy-vacancy interaction energies can be considered directly in an existing CALPHAD optimisation without losing any of the information already encoded within it. This was applied to a thermodynamic assessment in the literature and to a new assessment of the carbon-zirconium system that was performed incorporating new experimental insights.

description: We consider minimal type-I seesaw framework to realize $ μ-τ$ reflection symmetry in the low-energy neutrino mass matrix, $ M_ν $. Considering DUNE experiment, we scrutinize its potential to measure the precision of 2-3 mixing angle, $ θ_{23} $ and the Dirac CP-phase, $ δ$ for the given symmetry. Later, we examine the precision of these two parameters considering NuFit-3.2 data as one of the important true points. To study the low-energy phenomenology, we further discuss various breaking patterns of such an exact symmetry. Moreover, for each breaking scenario we perform the capability test of DUNE for the determination of $ θ_{23} $ and to establish the phenomenon of CP violation considering the true benchmark point arising from the breaking of $ μ-τ$ reflection symmetry. We also make remarks on the potential of DUNE to rule out maximal CP-violation or CP-conservation hypothesis at a certain confidence level for different scenarios.

Tools, data resources and methods for modelling climate change effects on plant disease
Creators: name: Sparks, Adam Henry
Publisher: name: Zenodo
Year: 2024

description: Modelling the effects of climate change on plant disease has been and continues to be animportant part of the work that plant disease experts. An important piece of the work is tochoose right methods, tools and data. There are several freely open source (FOSS) tools areavailable which do not require purchases and help make the work more widely shareable asanyone can download and install them without purchase. The programming languages, Julia,R and Python are all FOSS, and widely used in science which makes them ideal for this typeof work. Good quality historical and future climate data is main ingredient to do this type ofmodelling work. There are several freely available historical, current and future climate andweather data sources that are easily accessible through any of these three languages, e.g.,NASA POWER, GSOD, WORLDCLIM (Fick & Hijmans, 2017), but all have advantages anddisadvantages depending upon the type of work being conducted. Several approaches havebeen used for modelling the effects of climate change on plant disease, ranging frommechanistic (Jiranek et al., 2023) to statistical or empirical models (Bebber, 2019; Sparks etal., 2014) with linkages between different types of models being used as well (Duku et al.,2016) at geographic scales ranging from local to global and all scales in between. Due to theflexible nature of these tools, it is possible to use only one end-to-end to create whole pipelinesto carry out the work or combine them to use the best packages available for the task now thatit is much easier to seamlessly use these three languages together. All three languages offeruser-contributed packages that make this work easier, whether it is acquiring weather andclimate data, processing data statistical methods or even providing plant disease models. Allcan also easily handle modelling the effects of climate change on plant disease. The choicesmade will largely come down to the researcher’s comfort with any of the three first, andsecondly, the availability of the desired models or methods. I will discuss the support that allthree languages provide for these activities and provide a brief overview of climate andweather data sources and some of the modelling approaches that have been used as a primerto get started in this area.

description: An (improper) graph colouring has "defect" $d$ if each monochromatic subgraph has maximum degree at most $d$, and has "clustering" $c$ if each monochromatic component has at most $c$ vertices. This paper studies defective and clustered list-colourings for graphs with given maximum average degree. We prove that every graph with maximum average degree less than $\frac{2d+2}{d+2} k$ is $k$-choosable with defect $d$. This improves upon a similar result by Havet and Sereni [J. Graph Theory, 2006]. For clustered choosability of graphs with maximum average degree $m$, no $(1-ε)m$ bound on the number of colours was previously known. The above result with $d=1$ solves this problem. It implies that every graph with maximum average degree $m$ is $\lfloor{\frac{3}{4}m+1}\rfloor$-choosable with clustering 2. This extends a result of Kopreski and Yu [Discrete Math., 2017] to the setting of choosability. We then prove two results about clustered choosability that explore the trade-off between the number of colours and the clustering. In particular, we prove that every graph with maximum average degree $m$ is $\lfloor{\frac{7}{10}m+1}\rfloor$-choosable with clustering $9$, and is $\lfloor{\frac{2}{3}m+1}\rfloor$-choosable with clustering $O(m)$. As an example, the later result implies that every biplanar graph is 8-choosable with bounded clustering. This is the best known result for the clustered version of the earth-moon problem. The results extend to the setting where we only consider the maximum average degree of subgraphs with at least some number of vertices. Several applications are presented.
Far-Infrared Water Line Emissions From Circumstellar Outflows

description: We have modeled the far-infrared water line emission expected from circumstellar outflows from oxygen-rich late-type stars, as a function of the mass-loss rate and the terminal outflow velocity. For each mass-loss rate and terminal outflow velocity considered, we computed self-consistently the gas density, temperature, outflow velocity, and water abundance as a function of distance from the star. We then used an escape probability method to solve for the equilibrium level populations of 80 rotational states of water and thereby obtained predictions for the luminosity of a large number of far-infrared rotational transitions of water. In common with previous models, our model predicts that water will be copiously produced in the warm circumstellar gas, and that water rotational emission will dominate the radiative cooling. However, our use of a realistic radiative cooling function for water leads to a lower gas temperature than that predicted in previous models. Our predictions for the far-infrared water line luminosities are consequently significantly smaller than those obtained in previous studies. Observations to be carried out by the Infrared Space Observatory will provide a crucial test of the models presented here.

description: We present a high-dimensional analysis of three popular algorithms, namely, Oja's method, GROUSE and PETRELS, for subspace estimation from streaming and highly incomplete observations. We show that, with proper time scaling, the time-varying principal angles between the true subspace and its estimates given by the algorithms converge weakly to deterministic processes when the ambient dimension $n$ tends to infinity. Moreover, the limiting processes can be exactly characterized as the unique solutions of certain ordinary differential equations (ODEs). A finite sample bound is also given, showing that the rate of convergence towards such limits is $\mathcal{O}(1/\sqrt{n})$. In addition to providing asymptotically exact predictions of the dynamic performance of the algorithms, our high-dimensional analysis yields several insights, including an asymptotic equivalence between Oja's method and GROUSE, and a precise scaling relationship linking the amount of missing data to the signal-to-noise ratio. By analyzing the solutions of the limiting ODEs, we also establish phase transition phenomena associated with the steady-state performance of these techniques.

description: We present the first results from a major HST WFPC2 imaging study aimed at providing the first statistically meaningful comparison of the morphologies, luminosities, scalelengths and colours of the host galaxies of radio-quiet quasars, radio-loud quasars, and radio galaxies. We describe the design of this study and present the images which have been obtained for the first half of our 33-source sample. We find that the hosts of all three classes of luminous AGN are massive elliptical galaxies, with scalelengths ~=10 kpc, and R-K colours consistent with mature stellar populations. Most importantly this is the the first unambiguous evidence that, just like radio-loud quasars, essentially all radio-quiet quasars brighter than M_R = -24 reside in massive ellipticals. This result removes the possibility that radio `loudness' is directly linked to host galaxy morphology, but is however in excellent accord with the black-hole/spheroid mass correlation recently highlighted by Magorrian et al. (1998). We apply the relations given by Magorrian et al. to infer the expected Eddington luminosity of the putative black hole at the centre of each of the spheroidal host galaxies we have uncovered. Comparison with the actual nuclear R-band luminosities suggests that the black holes in most of these galaxies are radiating at a few percent of the Eddington luminosity; the brightest host galaxies in our low-z sample are capable of hosting quasars with M_R = -28, comparable to the most luminous quasars at z = 3. Finally we discuss our host-derived black-hole masses in the context of the radio-luminosity:black-hole mass correlation recently uncovered for nearby galaxies by Franceschini et al. (1998), and the resulting implications for the physical origin of radio loudness.

description: We present the results of deep Lyman limit imaging in four new fields as part of a continuing search for galaxies at $3.0 \le z \le 3.5$. The technique uses a custom broad--band filter set ($U_n G {\cal R}$) designed to isolate objects having Lyman continuum breaks superposed on otherwise flat--spectrum ultraviolet continua. The observations are specifically aimed at detecting known galaxies producing optically thick QSO metal line absorption systems, but are equally sensitive to more generally distributed objects at the redshifts of interest. Together with previously published results of the survey, we have now detected in two out of six cases objects with the expected properties of star--forming galaxies at $z \simgt 3$ within 3~arcsec of the QSO sight lines; the two candidate absorbers have similar luminosities, $M_B \simeq -22$ ($q_0=0.5$, $H_0=50$ \kms Mpc$^{-1}$), and impact parameters, $R \sim 10~h^{-1}$~kpc. The average surface density of robust Lyman break objects is $\sim 0.5$ galaxies per square arcminute to a magnitude limit ${\cal R} = 25.0$. A simple, ``no evolution'' model based on the properties of normal galaxies at $z \simlt 1$ predicts a density of Lyman break objects only a few times larger than observed. We conclude that there is a substantial population of star--forming galaxies, of relatively normal luminosity, already in place at $z = 3 - 3.5$.

Les 06 clubs ont été observé, 07 entretiens formels semi-directifs passés au DTN, aux présidents de Canon et d’APEJES, à leurs entraineurs et préparateurs physiques. Le cadre théorique retenu est celui de Bouarrata (2001). Seuls deux clubs ont un préparateur physique, qui utilise un matériel basique, ne fréquente pas les salles de fitness du fait des connaissances limitées et des moyens financiers insuffisants. Le métier de préparateur physique est embryonnaire dans le football camerounais, en attendant que ces acteurs lui reconnaissent son importance.

description: We have obtained low-resolution optical spectra of three faint brown dwarf candidates in the Pleiades open cluster. The objects observed are Roque 12 (I=18.5), Roque 5 (I=19.7) and Roque 25 (I=21.2). The spectrum of Roque 25 does not show the strong TiO bandheads that characterize the optical spectra of M-type stars, but molecular bands of CaH, CrH and VO are clearly present. We classify Roque 25 as an early L-type brown dwarf. Using current theoretical evolutionary tracks we estimate that the transition from M-type to L-type in the Pleiades (age ~ 120 Myr) takes place at Teff ~ 2200 K or M ~ 0.04 Msol. Roque 25 is a benchmark brown dwarf in the Pleiades because it is the first known one that belongs to the L-type class. It provides evidence that the IMF extends down to about 0.035 Msol, and serves as a guide for future deep searches for even less massive young brown dwarfs.

description: We present a detailed calculation of the propagation of AGN-like ionizing radiation through the intergalactic space. We model the ionization state of absorbing clouds, and show that the universe will be more opaque above $4\,$Ryd than previously estimated. Singly ionized helium in \Lya forest clouds and Lyman-limit systems is found to be very efficient in reprocessing soft X-ray, helium-ionizing photons into ultraviolet, hydrogen-ionizing ones. We demonstrate that a significant fraction of the absorbed primary photons (emitted, e.g., by quasar sources) will be reradiated by the photoionized gas through \Lya line emission, two-photon continuum, and recombination continuum radiation. In the light of new data and recent studies, we also reassess the contribution of the QSOs observed in optical surveys to the UV extragalactic background, and find that the stochastic reprocessing of quasar Lyman continuum radiation by hydrogen and helium along the line of sight will significantly affect the amplitude, spectral shape, and fluctuations properties of the metagalactic flux. In a scenario in which QSOs are the primary source of ionizing photons in the universe, the integrated \HI \Lya emission at $z=0$ from photoionized \Lya clouds and Lyman-limit systems is found to be at a level of less than 5\% of current observational limits on the far-UV extragalactic radiation flux. We show that $J_{912}$ increases from $\approx 10^{-23} \uvunits$ at the present epoch to $\approx 5\times 10^{-22}\uvunits$ at $z=2.5$. The attenuated direct quasar emission plus recombination radiation from intergalactic gas appears to provide enough hydrogen-ionizing photons to satisfy the proximity effect at large redshift. The \HeII/\HI ratio in the diffuse intergalactic medium and the \Lya clouds increases from $\approx25$ at

This thesis provides insight into the influence of dialysis modality on quality of life in older people with advanced kidney disease. It also explores the relationship between cognitive impairment and dialysis. Firstly, quality of life measures were compared between older patients on assisted peritoneal dialysis and haemodialysis. Patients on assisted peritoneal dialysis were matched to haemodialysis patients by baseline characteristics. Quality of life assessments were carried out quarterly for 2 years. Following multivariate analyses, there was no consistent difference in quality of life between patients on haemodialysis and assisted peritoneal dialysis. The second study assesses the influence of dialysis on cognition and patient reported outcome measures in patients with advanced kidney disease. Patients on haemodialysis, peritoneal dialysis or with chronic kidney disease (eGFR < 30ml/min) patients were recruited. Study participants were assessed 4 monthly for up to 2 years. Mixed model analysis showed that cognitive function declined faster in dialysis patients compared with non-dialysis patients with chronic kidney disease. In the dialysis cohort, executive function was better preserved in patients on peritoneal dialysis compared with haemodialysis patients. Dialysis did not consistently influence trends in patient reported outcome measures during follow up. Finally, the relationship between cognition and decision making capacity was explored in a small pilot of renal patients. Cognition and decision making capacity were assessed by the Montreal Cognitive Assessment and Macarthur Competence Assessment tools respectively. Patients with lower cognitive scores tended to have lower capacity assessment scores, albeit without reaching statistical significance. In older patients with advanced kidney disease, risk factors other than dialysis modality, influence quality of life. Cognitive decline, one such risk factor, may accelerate with dialysis depending on modality. It may also affect decision making. These findings highlight the need to screen for geriatric syndromes in older patients with renal disease.

description: We present the results of the monitoring of the GRB 970111 field that started 19 hours after the event. This observation represents the fastest ground-based follow-up performed for GRB 970111 in all wavelengths. As soon as the detection of the possible GRB 970111 X-ray afterglow was reported by Feroci et al. (1998) we reanalyzed the optical data collected for the GRB 970111 field. Although we detect small magnitude variability in some objects, no convincing optical counterpart is found inside the WFC error box. Any change in brightness 19 hours after the GRB is less than 0.2 mag for objects with B < 21 and R < 20.8. The bluest object found in the field is coincident with 1SAXJ1528.8+1937. Spectroscopic observations revealed that this object is a Seyfert-1 galaxy with redshift z=0.657, which we propose as the optical counterpart of the X-ray source. Further observations allowed to perform multicolour photometry for objects in the GRB 970111 error box. The colour-colour diagrams do not show any object with unusual colours. We applied a photometric classification method to the objects inside the GRB error box, that can distinguish stars from galaxies and estimate redshifts. We were able to estimate photometric redshifts in the range 0.2 < z < 1.4 for several galaxies in this field and we did not find any conspicuous unusual object. We note that GRB 970111 and GRB 980329 could belong to the same class of GRBs, which may be related to nearby sources (z ~1) in which high intrinsic absorption leads to faint optical afterglows.

Development and application of first-principles methods for complex oxide surfaces and interfaces
Creators: name: Greco, Andrea

description: In this thesis we develop and apply a variety of first-principles computational methods to the study of complex oxide heterostructures. Firstly, we introduce a new set of partially localised orbitals that offer a natural description for 1D- and 2D-periodic systems, providing the same accuracy as traditional plane-wave DFT-based approaches but with a computational cost that increases only linearly with the size of the system along the non-periodic directions, thus alleviating the unfavourable scaling of traditional DFT calculations. The method was implemented in the ONETEP code, which is a leading large-scale DFT code that was originally designed to work with fully localised orbitals and Gamma-point sampling only of the Brillouin zone. We show that the use of our new basis set in conjunction with the implementation of the Brillouin zone sampling at arbitrary k-points significantly extends the systems that can be studied with a DFT-based approach. We then discuss the performance of a force field parametrised to reproduce DFT energies, stresses and forces in bulk barium titanate (BTO), when it is applied to the study of BTO surfaces and interfaces. We find that, upon structural relaxation, the displacements of the surface atoms are qualitatively incorrect when compared with DFT predictions because of the different local environment with respect to the bulk, and that the transferability of the force field can be greatly improved by introducing a handful of extra parameters for the surface atoms only. We then explore interesting phenomena at the interface between two different complex oxides. We first analyse the possibility to induce oxygen octahedral distortions from a perovskite substrate into an originally undistorted film. We observe that for the system of interest (barium zirconate grown on top of strontium zirconate) the induced distortions have a non-negligible decay length of roughly 25 angstrom, and the gradients associated with the decaying modes can induce novel physical properties in the film. We finally explore the application of complex oxides as solid electrolytes in next-generation Li-ion batteries, a promising path towards the development of efficient, light and safe energy storage systems to be used in the transportation industry. We develop a custom framework to perform a preliminary screening of potential candidates, focusing on the requirement of the electrolyte to be stable against commonly used electrodes, and we find materials that are stable in contact with pure Li metal at significantly higher voltages than the traditional organic solvents used in current Li-ion batteries.

description: The report’s purpose is to summarize the results of Task T7.2 “Operational phase offshore”, presenting an overall blueprint of the activities conducted during the pre-operational phase. Hence, the blueprint synthesizes pre-test activities (tests on biofouling and monitoring tools development of site-specific monitoring programs, seaweed net and seeding strategy tests, material tests of oyster cultivation, etc.), material choices (selection of scour protection material, instrument choices, installation procedures, etc.), design set-ups (method of mooring, connectors, net systems vs. longlines), technical requirement specifications (e.g. estimation of minimum breaking loads), training and capacity building of personnel (e.g. offshore sea survival course, offshore first aid course) as well as health and safety issues, on which the operational offshore phase builds upon. The report depicts the planning stages (primarily from the bio-technology point of view as the planning of the licensing procedures are highly variable in various jurisdictions and will always require a site-specific approach) as well as a detailed description of the development trajectory of offshore multi-use concepts: combination of wind energy and seaweed-/ blue mussel research and production (German Pilot), floating solar energy production and seaweed culture (Dutch Pilot), wind energy production and seaweed-/oyster culture (Belgian Pilot), wind energy production and tourism (Danish Pilot) as well as fish aquaculture and tourism (Greek Pilot). Furthermore, simulations of the seaweed net design for the German, Dutch and Belgian Pilot were performed to determine an optimum choice for each site. In order to generate a complete report, not only concerning technological matters, but also most relevant environmental issues (i.e. revised assessment needs that differ from conventional approaches), social aspects (i.e. stakeholder engagement and consensus building), economic considerations (i.e. key performance indicators, specific to each pilot). Also, the legal aspects (i.e. national regulations & insurance specifically for the project partners but not EU wide) are addressed regarding every Pilot and pivotal requirements are presented and discussed.

description: We compute the anisotropic in-plane thermal conductivity of suspended single-layer black phosphorous (SLBP) using three molecular dynamics (MD) based methods, including the equilibrium MD method, the nonequilibrium MD (NEMD) method, and the homogeneous nonequilibrium MD (HNEMD) method. Two existing parameterizations of the Stillinger-Weber (SW) potential for SLBP are used. Consistent results are obtained for all the three methods and conflicting results from previous MD simulations are critically assessed. Among the three methods, the HNEMD method is the most and the NEMD method the least efficient. The thermal conductivity values from our MD simulations are about an order of magnitude larger than the most recent predictions obtained using the Boltzmann transport equation approach considering long-range interactions in density functional theory calculations, suggesting that the short-range SW potential might be inadequate for describing the phonon anharmonicity in SLBP.

description: We compute the shift in the epoch of matter-radiation equality due to the possible existence of a different statistical (non-extensive) background. The shift is mainly caused by a different neutrino-photon temperature ratio. We then consider the prospects to use future large galaxy surveys and cosmic microwave background measurements to constrain the degree of non-extensivity of the universe.

The accretion luminsoity of a massive black hole in an elliptical galaxy

Publisher: name: arXiv
Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: Most large elliptical galaxies should now host a massive black hole leftover from an earlier quasar phase. Such galaxies also have an extensive hot gaseous halo. Here we consider why the nuclei of elliptical galaxies are not luminous sources due to the accretion of the hot gas by the central black hole, yet have weak radio sources. In particular we suggest that accretion from the hot medium has low radiative efficiency and forms a hot ion torus surrounding the black hole. Synchrotron emission from the torus can account for at least part of the weak radio sources commonly seen in otherwise normal elliptical galaxies. The inner funnel of the ion torus can also begin the collimation of a narrow jet. We speculate on the difference between jets from the nuclei of spiral and elliptical galaxies and suggest that the extensive hot atmosphere seen in ellipticals is essential for maintaining the collimation and provoking the observed radio structures of radio galaxies. We also note that low radiative efficiency, and not necessarity a large change in accretion rate, may be responsible for the demise of quasars and may contribute to the hard X-ray Background. Hot ion tori may be common in galactic nuclei.
