The critical role of monocytes In transplant-related acute lung injury
Creators: name: Tatham, Kate
Publisher: name: Imperial College London
Year: 2015

description: Lung transplantation remains the final option for patients with end-stage lung disease. A significant proportion will develop primary graft dysfunction acutely post implantation, severely impacting on their morbidity and mortality. A key role for marginated monocytes has been identified in several experimental models of lung injury. Whilst other inflammatory leukocytes have been implicated in the pathogenesis of lung ischaemia-reperfusion injury (and primary graft dysfunction), a specific role for vascular monocytes has not yet been fully investigated. We hypothesised that marginated lung monocytes played a critical role in the pathogenesis of lung ischaemia-reperfusion injury. Our overall aims were to: (a) develop, optimise and characterise a murine model of ischaemia-reperfusion, utilising the isolated perfused lung system, (b) elucidate the role of monocytes with liposomal-clodronate depletion and adoptive transfer, and (c) to identify and characterise monocytes in human lung transplant samples and correlate them to patient outcomes. The major findings of this work were that lung marginated monocytes are retained and activated following ischaemia-reperfusion injury, inducing inflammatory mediator release. Clodronate depletion of vascular monocytes resulted in reversal of the injury and abrogated mediator release. Moreover, vascular monocyte repletion (via adoptive transfer), reinstated the injury and inflammation originally observed. Analysis of human lung samples, flushed prior to implantation, also demonstrated significant monocyte retention and activation, which correlated with primary graft dysfunction, in a pilot study of transplant recipients. In summary, this study was able to confirm a critical role for marginated monocytes in lung ischaemia-reperfusion injury. A significant number were retained, and activated, in both murine and human lung samples despite considerable pulmonary flushing. This indicates a propensity for these monocytes to be transferred as ‘passenger’ cells to recipients, where they are capable of the propagation of lung inflammation and injury following transplantation.
Contribution of Type Ia and Type II Supernovae for Intra-Cluster Medium Enrichment

description: The origin of the chemical composition of the intracluster medium (ICM) is discussed in this paper. In particular, the contribution from Type Ia supernovae (SNe Ia) to the ICM enrichment is shown to exist by adopting the fitting formulas which have been used in the analysis of the solar system abundances. Our analysis means that we can use the frequency of SNe Ia relative to SNe II as the better measure than $M_{Fe, SN Ia}/M_{Fe, total}$ for estimating the contribution of SNe Ia. Moreover, the chemical compositions of ICMs are shown to be similar to that of the solar system abundances. We can also reproduce the sulfur/iron abundance ratio within a factor of 2, which means that the abundance problem of sulfur needs not to be emphasized too strongly. We need more precise observations to conclude whether ICMs really suffer the shortage problem of sulfur or not.

description: A Majorana-based qubit can form within the fermion parity subspace of a two-island topological superconductor setup consisting of four Majorana zero modes. We study the relaxation time of this Majorana qubit induced by the intrinsic Majorana-phonon interaction in combination with single electron tunneling between the two islands. The theory is developed for both the spinless p-wave Kitaev chain model and the spin-orbit-coupled semiconductor nanowire with induced superconductivity and Zeeman splitting. We systematically discuss the dependence of the relaxation rate on Majorana charge distribution (varying with the chemical potential, magnetic field, superconducting paring, spin-orbit coupling and island length) as well as on phonon wavelength and the length of the tunnel barrier. Importantly, the accompanied phonon energy can be tuned by the voltage bias over the tunnel barrier, leading to relatively easy manipulation and suppression of the relaxation rate.

description: Two main features of the observable distribution of visible matter are the space correlations of galaxy positions and the mass function of galaxies. As discussed in Pietronero and Sylos Labini on this issue ([1], see also [2],[3]), the concept of multifractal (MF) distribution (including the masses) naturally unifies these two properties. Hence with the knowledge of the whole MF spectrum one obtains information on the correlations in space as well as on the mass function. From a theoretical point of view one would like to identify the dynamical process that leads to such a MF distribution. In order to gain some insight into this complex problem we have developed a simple stochastic model that includes some of the basic properties of aggregation process and allows us to pose a variety of interesting question concerning the possible dynamical origin of the MF distribution. The dynamics is characterised by some parameters, that have a direct physical meaning in term of cosmological processes. In this way we can relate the input parameters of the dynamics to the properties of the final configuration and produce a sort of phase diagram.

Resolving the virial discrepancy in clusters of galaxies with modified Newtonian dynamics

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A sample of 197 X-ray emitting clusters of galaxies is considered in the context of Milgrom's modified Newtonian dynamics (MOND). It is shown that the gas mass, extrapolated via an assumed $β$ model to a fixed radius of 3 Mpc, is correlated with the gas temperature as predicted by MOND ($M_g \propto T^2$). The observed temperatures are generally consistent with the inferred mass of hot gas; no substantial quantity of additional unseen matter is required in the context of MOND. However, modified dynamics cannot resolve the strong lensing discrepancy in those clusters where this phenomenon occurs. The prediction is that additional baryonic matter may be detected in the central regions of rich clusters.

description: The basic hypothesis of a post-Copernican Cosmological theory is that {\em all the points} of the Universe have to be essentially equivalent: this hypothesis is required in order to avoid any privileged {\em observer}. This assumption has been implemented by Einstein in the so-called Cosmological Principles (CP): {\em all the positions} in the Universe have to be essentially equivalent, so that the Universe is homogeneous. This situation implies also the condition of spherical symmetry about every point, so that the Universe in also Isotropic. There is a hidden assumption in the formulation of the CP in regard to the hypothesis that all the points are equivalent In fact, the condition that all the occupied points are statistically equivalent with respect to their environment correspond to the property of of Local Isotropy. It is generally believed that the Universe cannot be isotropic about every point without being also homogeneous [1]. Actually Local Isotropy does not necessarily implies homogeneity; in fact a topology theorem states that homogeneity is implied by the condition of local isotropy together with {\em the assumption of the analyticity or regularity} for the distribution of matter. Up to the seventies analyticity was an obvious implicit assumption in any physical problem. Recently however we have learned about intrinsically irregular structures for which analyticity should be considered as a property to be tested with appropriate analysis of experiment.

description: Lattice-based stochastic simulators are commonly used to study biological reaction-diffusion processes. Some of these schemes that are based on the reaction-diffusion master equation (RDME), can simulate for extended spatial and temporal scales but cannot directly account for the microscopic effects in the cell such as volume exclusion and diffusion-influenced reactions. Nonetheless, schemes based on the high-resolution microscopic lattice method (MLM) can directly simulate these effects by representing each finite-sized molecule explicitly as a random walker on fine lattice voxels. The theory and consistency of MLM in simulating diffusion-influenced reactions have not been clarified in detail. Here, we examine MLM in solving diffusion-influenced reactions in 3D space by employing the Spatiocyte simulation scheme. Applying the random walk theory, we construct the general theoretical framework underlying the method and obtain analytical expressions for the total rebinding probability and the effective reaction rate. By matching Collins-Kimball and lattice-based rate constants, we obtained the exact expressions to determine the reaction acceptance probability and voxel size. We found that the size of voxel should be about 2% larger than the molecule. MLM is validated by numerical simulations, showing good agreement with the off-lattice particle-based method, eGFRD. MLM run time is more than an order of magnitude faster than eGFRD when diffusing macromolecules with typical concentrations in the cell. MLM also showed good agreements with eGFRD and mean-field models in case studies of two basic motifs of intracellular signaling, the protein production-degradation process and the dual phosphorylation cycle. Moreover, when a reaction compartment is populated with volume-excluding obstacles, MLM captures the non-classical reaction kinetics caused by anomalous diffusion of reacting molecules.

Year: 1995
Subjects: subject: Astrophysics (astro-ph)

description: It is greatly expected that the relic neutrino background from past supernovae is detected by Superkamiokande (SK) which is now under construction. We calculate the spectrum and the event rate at SK systematically by using the results of simulations of a supernova explosion and reasonable supernova rates. We also investigate the effect of a cosmological constant, $Λ$, on the spectrum, since some recent cosmological observations strongly suggest the existence of $Λ$. We find following results. 1) The spectrum has a peak at about 3 MeV, which is much lower than that of previous estimate ($6 \sim$ 10 MeV). 2) The event rate at SK in the range from 10 MeV to 50 MeV, where the relic neutrinos from past supernovae is dominant, is about $25 \, {h_{50}}^2 \, \left( \frac{R_{SN}}{0.1 {\rm yr^{-1}}} \right) \left(\frac{n_G \, h_{50}^{-3}}{0.02{\rm Mpc}^{-3}}\right)$ events per year, where $R_{SN}$ is the supernova rate in a galaxy, $n_G$ is the number density of galaxies, and $h_{50} = H_0 /$ (50km/s/Mpc), where $H_0$ is the Hubble constant. 3) The event rate is almost insensitive to $Λ$. The flux increases in the low energy side ($< 10$ MeV) with increasing $Λ$, but decreases in the high energy side (10 MeV $

description: Ship detection is of great importance and full of challenges in the field of remote sensing. The complexity of application scenarios, the redundancy of detection region, and the difficulty of dense ship detection are all the main obstacles that limit the successful operation of traditional methods in ship detection. In this paper, we propose a brand new detection model based on multitask rotational region convolutional neural network to solve the problems above. This model is mainly consist of five consecutive parts: Dense Feature Pyramid Network (DFPN), adaptive region of interest (ROI) Align, rotational bounding box regression, prow direction prediction and rotational nonmaximum suppression (R-NMS). First of all, the low-level location information and high-level semantic information are fully utilized through multiscale feature networks. Then, we design Adaptive ROI Align to obtain high quality proposals which remain complete spatial and semantic information. Unlike most previous approaches, the prediction obtained by our method is the minimum bounding rectangle of the object with less redundant regions. Therefore, rotational region detection framework is more suitable to detect the dense object than traditional detection model. Additionally, we can find the berthing and sailing direction of ship through prediction. A detailed evaluation based on SRSS for rotation detection shows that our detection method has a competitive performance.
Calcium phosphate scaffolds with controlled properties for biological applications
Creators: name: Da Costa Machado, Gil Daniel
Publisher: name: Imperial College London
Year: 2016

description: The last few decades have seen major advances in the field of materials for healthcare applications. New approaches call for the development of biomaterials with controlled chemistry, tailored structure at different length scales and adequate degradation and dissolution profiles, all of which are crucial to the success of biomaterials for tissue regenerative therapies. Calcium phosphates are widely used to promote recovery of bone tissue due to their chemically similarity to the inorganic phase of bone. And although they have had considerable success, a discussion remains about the optimum characteristics of a bone substitute. This work aimed to develop a framework to study the combined effect of surface microroughness of calcium phosphates with varying composition - Hydroxyapatite (HA) to β-Tricalcium Phosphate (β-TCP), including biphasic materials - on human mesenchymal stem cells in vitro. Furthermore, the method used to tailor such microstructural features is translatable into 3D-printed scaffolds, i.e., it was possible to fabricated materials with complex structures, while controlling surface roughness. The thermal behaviour of calcium phosphate materials with different Ca/P ratio was studied, and adequate sintering conditions were optimised. These avoid the β to α transformation in materials with TCP. A novel processing route to control microstructure was developed: ceramic materials were functionalised with a pH-responsive polymer and used to stabilise microemulsions, where the hydrophobic phase was used as a soft porogen that evaporates. Independently of the HA/β-TCP ratio used, interconnected microporosity was obtained as a result of the emulsification process. The osteogenic potential of discs with these surface properties and three different chemical compositions (pure HA, pure β-TCP and a biphasic material HA/β-TCP) was evaluated in cultures with hMSCs from three independent donors. Finally, the behaviour of particle-stabilised emulsions was optimised to be used as inks for robocasting. Rheological characterisation and extrusion flow tests clarified the impact of different processing steps in their printability. In the end, calcium phosphate scaffolds with complex shapes and controlled chemistry and surface features (resulting from the oil templating) were fabricated.

The role of sulfate minerals in the search for evidence of life on Mars
Creators: name: Lewis, James Michael Timothy
Publisher: name: Imperial College London
Year: 2015

description: Spacecraft sent to Mars have revealed that some ancient martian environments were habitable for life. Attempting to detect the organic matter that this potential life may have left behind has been a priority for several missions. However, the search for both biotic and abiotic organic compounds on Mars has yielded only organochlorines, which have an ambiguous origin. Recently it has been recognised that perchlorate (ClO4-) salts found on the surface of Mars are interfering with the heating experiments used by rovers and landers to search for organic matter. The potential for other oxygen-containing salts to disrupt thermal experiments has received comparatively little attention. In this thesis it is shown that the iron sulfate mineral jarosite thermally decomposes and releases oxygen at temperatures that would interfere with the detection of macromolecular organic matter. Experiments using synthetic jarosite samples revealed that during thermal decomposition sulfur dioxide and oxygen are released concurrently at a ratio of 2:1. In the presence of organic matter only the sulfur dioxide is detected, along with the carbon dioxide resulting from the combustion of carbon compounds. Prolonged exposure to water eventually causes jarosite to decompose into goethite. It was found that goethite can retain organic matter that was originally preserved in jarosite. The results demonstrate that though jarosite should be considered a problematic mineral for thermal experiments on Mars, goethite deposits in close proximity to jarosite may be good targets for organic matter detection. Jarosite and goethite have been observed on Mars by both rovers and orbiters. The transition from a habitable world to the present environment was marked by volcanism that created jarosite-forming, acidic, sulfur-rich conditions. The improved knowledge of the thermal extraction of jarosite and goethite containing samples will therefore be relevant in the analysis of a significant part of Mars’ geological history.

description: Heat-transfer through weakly magnetized diffuse astrophysical plasmas excites whistlers. This leads to electron whistler resonant scattering, a reduction of the electron mean-free path, and heat-flux inhibition. However, only whistlers propagating at a finite angle to the magnetic field (off-axis) can scatter the heat-flux carrying electrons. Thus, the level of heat flux-inhibition along the magnetic field lines depends on the presence of off-axis whistlers.

description: Super-resolution fluorescence microscopy, with a resolution beyond the diffraction limit of light, has become an indispensable tool to directly visualize biological structures in living cells at a nanometer-scale resolution. Despite advances in high-density super-resolution fluorescent techniques, existing methods still have bottlenecks, including extremely long execution time, artificial thinning and thickening of structures, and lack of ability to capture latent structures. Here we propose a novel deep learning guided Bayesian inference approach, DLBI, for the time-series analysis of high-density fluorescent images. Our method combines the strength of deep learning and statistical inference, where deep learning captures the underlying distribution of the fluorophores that are consistent with the observed time-series fluorescent images by exploring local features and correlation along time-axis, and statistical inference further refines the ultrastructure extracted by deep learning and endues physical meaning to the final image. Comprehensive experimental results on both real and simulated datasets demonstrate that our method provides more accurate and realistic local patch and large-field reconstruction than the state-of-the-art method, the 3B analysis, while our method is more than two orders of magnitude faster.

description: We extend the disformal transformation to models with two scalar fields and look at its singular limit. Solving the eigentensor equation for the Jacobian of the transformation of the metrics we find the two-field extension of the mimetic scenario in the singular conformal limit. At the background level the setup mimics the roles of dark matter cosmology. We decompose the perturbations into the adiabatic and entropy modes in which the adiabatic perturbation is tangential to the classical trajectory while the entropy mode is perpendicular to it. We show that the adiabatic mode is frozen while the entropy mode propagates with the sound speed equal to unity with no instabilities.

Every quasar with a low-frequency (151 MHz) radio flux-density S_151 > 0.5 Jy in two regions of the sky covering 0.013 sr is included; 23 of these have sufficient extended flux to meet the selection criteria, 18 of these have steep radio spectra (hereafter denoted as SSQs). The key advantage of this sample over most samples of RLQs is the lack of an optical magnitude limit. By combining the 7C and 3CRR samples, we have investigated the properties of RLQs as a function of redshift z and radio luminosity L_151. We derive the radio luminosity function (RLF) of RLQs and find that the data are well fitted by a single power-law with slope alpha_1=1.9. We find that there must be a break in the RLQ RLF at log_10(L_151 / W Hz^-1 sr^-1) < 27, in order for the models to be consistent with the 7C and 6C source counts. The z-dependence of the RLF follows a one-tailed gaussian which peaks at z=1.7. We find no evidence for a decline in the co-moving space density of RLQs at higher redshifts. A positive correlation between the radio and optical luminosities of SSQs is observed, confirming a result of Serjeant et al. (1998). We are able to rule out this correlation being due to selection effects or biases in our combined sample. The radio-optical correlation and best-fit model RLF enable us to estimate the distribution of optical magnitudes of quasars in samples selected at low radio frequencies. We conclude that for samples with S_151 < 1 Jy one must use optical data significantly deeper than the POSS-I limit (R approx 20), in order to avoid severe incompleteness.

Dinitrogen activation and reduction with iron phosphine complexes
Creators: name: Doyle, Laurence

description: The conversion of dinitrogen to ammonia is a fundamental process for sustaining life on our planet. Ammonia provides a source of fixed nitrogen for nitrification and assimilation into plants, and is the ultimate source of almost all nitrogenated compounds. Synthetic ammonia is produced on a colossal scale by the Haber Bosch process, with an annual ammonia output exceeding 130 million tonnes. However, the intensive operating conditions of this process require a staggering energy cost; hence, the development of a lower energy solution is recognised as one of the major challenges of modern chemistry. This dissertation explores the chemistry of homogeneous systems based on iron diphosphine complexes that are able to transform coordinated dinitrogen into ammonia. A greater understanding of these systems may provide insight into the iron-based catalysts utilised in both biological nitrogen fixation and the industrial Haber Bosch process. Ultimately, this could lead to a more sustainable process for meeting the global requirement for fixed nitrogen. Chapter 1 provides a general introduction into dinitrogen fixation chemistry, with a particular focus on homogeneous systems involving iron. Chapter 2 describes a convenient synthetic protocol to 1,2-bis(dialkylphosphino)ethanes. These are among the most versatile ligands used in inorganic chemistry, although issues with prior syntheses, often involving extremely hazardous phosphine precursors, has limited their accessibility. Chapter 3 is an exploration of a seminal work on dinitrogen fixation involving iron complexes, which facilitate the conversion of coordinated dinitrogen to ammonia in what is known as the Leigh cycle. Mechanistic understanding of the key ammonia producing step has provided the focus of considerable interest and speculation for over a decade. Chapter 4 provides insight into the dinitrogen and dihydrogen affinity of an iron(I) complex. Chapter 5 details the experimental procedures performed in this work.
Non-intrusive estimation of acoustic parameters from degraded speech

description: Estimation of the acoustic parameters Signal-to-Noise Ratio (SNR), Reverberation Time (T60), Direct-to-Reverberant Ratio (DRR), and clipping level from degraded speech are open research questions. These parameters are important for determining speech quality and intelligibility, and they are widely applicable to speech enhancement and speech recognition systems. Whilst SNR, T60, and DRR are useful priors for dereverberation schemes, indications of clipping and the clipping level are useful for signal restoration. This thesis investigates how accurately and robustly to noise and, in the case of clipping detection, robustness to the coding and decoding process it is possible to estimate these parameters non-intrusively from degraded speech in real-time or near real-time, and introduces a range of novel algorithms. Alongside the algorithms, an international research challenge was staged for which a novel noisy reverberant speech corpus was developed to determine the state-of-the-art in T60 and DRR estimation. In tests, the algorithms presented in this thesis were highly competitive, being able to estimate T60 with Pearson correlation coefficient, ρ = 0.608 and DRR with ρ = 0.314. Both algorithms achieved very low computational complexity with Real-Time Factors (RTFs) of 0.0164 and 0.0589 respectively. The clipping detection algorithms achieved F1 approximately 0.6 for Global System For Mobile Communications (GSM) 06.10 decoded speech, babble noise at 20 dB SNR clipping levels in the range -5 to -20dBFS, and also produce an estimate of the original unclipped signal level.

description: Oesophageal cancer is the 13th most common cancer in the UK, but 6th most common cause of cancer death with only 15% of patients surviving 5 years (1). The disparity between incidence and mortality is due to the fact that a large proportion of oesophageal cancers are diagnosed at a late stage (2). This thesis aims to investigate the patterns of management and outcomes associated with the treatment of early neoplastic changes in the oesophagus in England, in order to try and identify areas where care may be improved. Four separate studies were performed on i) the management of high grade dysplasia (HGD) in England, ii) the proportion of oesophageal cancers missed at endoscopy, iii) the management and outcomes for early oesophageal cancer and iv) the safety and efficacy of radiofrequency ablation and complete endoscopic resection in the management of dysplastic Barrett’s oesophagus . These studies (expect study iv, which is a systematic review) were performed by linking three national databases, the National Oesophago-Gastric Cancer database, Hospital Episode Statistics and Office for National Statistics mortality data. The results of our studies highlight, that 1. a third of patients with HGD are managed by surveillance alone, with patients treated in low volume centres more likely to be managed in this manner, 2. a substantial proportion of cancers were missed at endoscopy, 3. only 6.8% of oesophageal cancers were diagnosed at an early stage, but two thirds of these patients survived 5 years if managed curatively 4. radiofrequency ablation should be used in preference to complete endoscopic resection in the management of dysplastic Barrett’s. Therefore there is still substantial room to improve the quality of care received by patients with early neoplastic changes in the oesophagus in England.
Polymer-templated synthesis of nanoparticles

Publisher: name: Imperial College London

description: This thesis describes the synthesis of nanoparticles in the cores of spherical micelles of poly(styrene)-b-poly(2-vinylpyridine) (PS-b-P2VP) and the subsequent deposition of these nanoparticle loaded micelles onto substrates, generating self-assembled nanomaterials with precisely-tuned regularly-spaced nanoparticles. Combining this bottom-up method of nanopatterning with top-down lithographic techniques allowed for the production of more complex surface patterns. Specifically, nanoparticles of Au, ZnS and Ag2S were synthesized. The formation mechanism of ZnS and Au nanoparticles were investigated using small angle X-ray scattering (SAXS). Single gold nanoparticles with diameters ranging from 4–12 nm were produced in the P2VP cores, with the size of the particles directly related to the ionic loading of the micelles. ZnS nanoparticles synthesized using this method had a unique hybrid substructure, consisting of small crystallites of ZnS embedded in an amorphous matrix composed of ZnS and the core-forming polymer. The size of the ZnS nanoparticles was dependent on the size of the ion-loaded core prior to sulfidation. The synthesis method was developed further by synthesizing multiple Ag2S particles in the micelle cores, that grew over time. Surface deposition of ZnS nanoparticle loaded micelles and subsequent exposure to hydrogen plasma and UV/ozone in order to remove the polymer shell resulted in the formation of ZnS nanoarrays on silicon and glass substrates, whose interparticle spacing could be directly controlled by varying the deposition protocol. The functionalization of these nanopatterned surfaces was successfully achieved via the attachment of poly-histidine tagged ICAM-1/CD54 to the nanoparticles surface. The capability of producing micropatterns of the ZnS nanoparticles was demonstrated by applying photolithography and focused ion beam lithography to surface deposited nanoparticle loaded micelles. In this way, it was possible to create regions of the substrate with or without ZnS nanoparticles.

description: Let $Z$ be a standard normal random variable and let $H_n$ denote the $n$-th Hermite polynomial. In this note, we obtain Stein equations for the random variables $H_3(Z)$ and $H_4(Z)$, which represents a first step towards developing Stein's method for distributional limits from the third and fourth Wiener chaoses. Perhaps surprisingly, these Stein equations are fifth and third order linear ordinary differential equations, respectively. As a warm up, we obtain a Stein equation for the random variable $aZ^2+bZ+c$, $a,b,c\in\mathbb{R}$, which leads us to a Stein equation for the non-central chi-square distribution. We also provide a discussion as to why obtaining Stein equations for $H_n(Z)$, $n\geq5$, is more challenging.

description: A variety of current models for gamma-ray bursts (GRBs) suggest a common engine - a black hole of several solar masses accreting matter from a disk at a rate 0.01 to 10 solar masses per second. Using a numerical model for relativistic disk accretion, we have studied steady-state accretion at these high rates. Inside a radius ~ 10**8 cm, for accretion rates greater than about 0.01 solar masses per second, a global state of balanced power comes to exist between neutrino losses, chiefly pair capture on nucleons, and dissipation. Energy emitted in neutrinos is less, and in the case of low accretion rates, very much less, than the maximum efficiency factor for black hole accretion (0.057 for no rotation; 0.42 for extreme Kerr rotation) times Mdot c**2. The efficiency for producing a pair fireball along the rotational axis by neutrino annihilation is calculated and found to be highly variable and very sensitive to the accretion rate. For some of the higher accretion rates studied, it can be several per cent or more; for accretion rates less than 0.05 solar masses per second, it is essentially zero. The efficiency of the Blandford-Znajek mechanism in extracting rotational energy from the black hole is also estimated. In light of these results, the viability of various gamma-ray burst models is discussed and the sensitivity of the results to disk viscosity, black hole rotation rate, and black hole mass explored. A diverse range of GRB energies seems unavoidable and neutrino annihilation in hyper-accreting black hole systems can explain bursts up to 10**52 erg. Larger energies may be inferred for beaming systems.

The Physical Origin of Scale Dependent Bias in Cosmological Simulations

description: Using large-scale hydrodynamic simulations with heuristic criteria for galaxy formation, we investigate how the galaxy field is related to the mass density and the gas temperature. We find that the bias b(R) = sigma_g(R)/sigma(R), where sigma_g(R) is the variance of galaxy counts in spheres of radius R and sigma(R) is the same for mass, varies from 2.6 at 1 h^{-1} Mpc to 1.2 at 30 h^{-1} Mpc. Including the dependence of the galaxy density on local gas temperature as well as on local mass density can fully account for this scale dependence. Galaxy density depends on temperature because gas which is too hot cannot cool to form galaxies; this causes scale dependence of b(R) because local gas temperature is related to the gravitational potential, and thus contains information about the large scale density field. We show that temperature dependence generally causes b(R) to vary on quasilinear and nonlinear scales, indicating that scale dependence of bias may be a generic effect in realistic galaxy formation scenarios. We find that the relationship between the galaxy and mass density fields is also a function of galaxy age. On large scales, the older galaxies are highly biased (b ~ 1.7) and highly correlated (r ~ 1.0) with the mass density field; younger galaxies are not biased (b ~ 0.8) and are poorly correlated (r ~ 0.5) with the mass. We argue that linear bias is inadequate to describe the relationship between galaxies and mass. (Abridged)
