Laing a aumentar sus ingresos y de ese modo pasar a formar parte de su vida, en 1981 le sugerí a Laing que escribiera un libro para decir a sus lectores cómo tener una relación terapéutica con una persona elegida con cuidado fuera de los límites de la terapia. De inmediato contestó con la propuesta de que me reuniera con él en Londres para escribir ese libro, y, al hacerlo, pudiéramos poner a prueba este tipo de relación constructiva nosotros mismos. Nuestro propósito era crear un “manual de instrucciones” exitoso y aumentar nuestras opciones personales como uno lo hace en una terapia exitosa. Así fue como empezó este libro, que es en realidad una auténtica historia de amor.

description: In order to mimic the phase changes in the primordial Big Bang, several "cosmological" solid-state experiments have been conceived, during the last decade, to investigate the spontaneous symmetry breaking in superconductors and superfluids cooled through their transition temperature. In one of such experiments the number of magnetic flux quanta spontaneously trapped in a superconducting loop was measured by means of a long Josephson tunnel junction built on top of the loop itself. We have analyzed this system and found a number of interesting features not occurring in the conventional case with simply connected electrodes. In particular, the fluxoid quantization results in a frustration of the Josephson phase, which, in turn, reduces the junction critical current. Further, the possible stable states of the system are obtained by a self-consistent application of the principle of minimum energy.

description: We study a general model describing a self-detecting single electron transistor realized by a suspended carbon nanotube actuated by a nearby antenna. The main features of the device, recently observed in a number of experiments, are accurately reproduced. When the device is in a low current-carrying state, a peak in the current signals a mechanical resonance. On the contrary, a dip in the current is found in high current-carrying states. In the nonlinear vibration regime of the resonator, we are able to reproduce quantitatively the characteristic asymmetric shape of the current-frequency curves. We show that the nonlinear effects coming out at high values of the antenna amplitude are related to the effective nonlinear force induced by the electronic flow. The interplay between electronic and mechanical degrees of freedom is understood in terms of an unifying model including in an intrinsic way the nonlinear effects driven by the external probe.

Heat transport and flow structure in rotating Rayleigh-Bénard convection

description: Here we summarize the results from our direct numerical simulations (DNS) and experimental measurements on rotating Rayleigh-Bénard (RB) convection. Our experiments and simulations are performed in cylindrical samples with an aspect ratio Γvarying from 1/2 to 2. Here Γ=D/L, where D and L are the diameter and height of the sample, respectively. When the rotation rate is increased, while a fixed temperature difference between the hot bottom and cold top plate is maintained, a sharp increase in the heat transfer is observed before the heat transfer drops drastically at stronger rotation rates. Here we focus on the question of how the heat transfer enhancement with respect to the non-rotating case depends on the Rayleigh number Ra, the Prandtl number Pr, and the rotation rate, indicated by the Rossby number Ro. Special attention will be given to the influence of the aspect ratio on the rotation rate that is required to get heat transport enhancement. In addition, we will discuss the relation between the heat transfer and the large scale flow structures that are formed in the different regimes of rotating RB convection and how the different regimes can be identified in experiments and simulations.

description: The resonant excitation of neutron star (NS) modes by tides is investigated as a source of short gamma-ray burst (sGRB) precursors. We find that the driving of a crust-core interface mode can lead to shattering of the NS crust, liberating ~10^46-10^47 erg of energy seconds before the merger of a NS-NS or NS-black hole binary. Such properties are consistent with Swift/BAT detections of sGRB precursors, and we use the timing of the observed precursors to place weak constraints on the crust equation of state. We describe how a larger sample of precursor detections could be used alongside coincident gravitational wave detections of the inspiral by Advanced LIGO class detectors to probe the NS structure. These two types of observations nicely complement one another, since the former constrains the equation of state and structure near the crust-core boundary, while the latter is more sensitive to the core equation of state.

description: We study strongly graded vertex algebras and their strongly graded modules, which are conformal vertex algebras and their modules with a second, compatible grading by an abelian group satisfying certain grading restriction conditions. We consider a tensor product of strongly graded vertex algebras and its tensor product strongly graded modules. We prove that a tensor product of strongly graded irreducible modules for a tensor product of strongly graded vertex algebras is irreducible, and that such irreducible modules, up to equivalence, exhaust certain naturally defined strongly graded irreducible modules for a tensor product of strongly graded vertex algebras. We also prove that certain naturally defined strongly graded modules for the tensor product strongly graded vertex algebra are completely reducible if and only if every strongly graded module for each of the tensor product factors is completely reducible. These results generalize the corresponding known results for vertex operator algebras and their modules.

description: The Ultrarelativistic Quantum Molecular Dynamics [UrQMD] model is widely used to simulate heavy ion collisions in broad energy ranges. It consists of various components to implement the different physical processes underlying the transport approach. A major building block are the shared tables of constants, implementing the baryon masses and widths. Unfortunately, many of these input parameters are not well known experimentally. In view of the upcoming physics program at FAIR, it is therefore of fundamental interest to explore the stability of the model results when these parameters are varied. We perform a systematic variation of particle masses and widths within the limits proposed by the particle data group (or up to 10%). We find that the model results do only weakly depend on the variation of these input parameters. Thus, we conclude that the present implementation is stable with respect to the modification of not yet well specified particle parameters.

description: Calculation of the energies, magnetic dipole hyperfine structure constants, E1 transition amplitudes between the low-lying states, and nuclear spin-dependent parity-nonconserving amplitudes for the ^2S_{1/2} - ^2D_{3/2,5/2} transitions in ^{171}Yb^+ ion is performed using two different approaches. First, we carried out many-body perturbation theory calculation considering Yb^+ as a monovalent system. Additional all-order calculations are carried out for selected properties. Second, we carried out configuration interaction calculation considering Yb as a 15-electron system and compared the results obtained by two methods. The accuracy of different methods is evaluated. We find that the monovalent description is inadequate for evaluation of some atomic properties due to significant mixing of the one-particle and the hole-two-particle configurations. Performing the calculation by such different approaches allowed us to establish the importance of various correlation effects for Yb^+ atomic properties for future improvement of theoretical precision in this complicated system.

QCD resummation for light-particle jets

Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We construct an evolution equation for the invariant-mass distribution of light-quark and gluon jets in the framework of QCD resummation. The solution of the evolution equation exhibits a behavior consistent with Tevatron CDF data: the jet distribution vanishes in the small invariant-mass limit, and its peak moves toward the high invariant-mass region with the jet energy. We also construct an evolution equation for the energy profile of the light-quark and gluon jets in the similar framework. The solution shows that the energy accumulates faster within a light-quark jet cone than within a gluon jet cone. The jet energy profile convoluted with hard scattering and parton distribution functions matches well with the Tevatron CDF and the large-hadron-collider (LHC) CMS data. Moreover, comparison with the CDF and CMS data implies that jets with large (small) transverse momentum are mainly composed of the light-quark (gluon) jets. At last, we discuss the application of the above solutions for the light-particle jets to the identification of highly-boosted heavy particles produced at LHC.

description: Entangling a mechanical oscillator with an optical mode is an enticing and yet a very challenging goal in cavity optomechanics. Here we consider a pulsed scheme to create Einstein-Podolsky-Rosen-type entanglement between a traveling-wave light pulse and a mechanical oscillator. The entanglement can be verified unambiguously by a pump-probe sequence of pulses. In contrast to schemes that work in a steady-state regime under a continuous-wave drive, this protocol is not subject to stability requirements that normally limit the strength of achievable entanglement. We investigate the protocol's performance under realistic conditions, including mechanical decoherence, in full detail. We discuss the relevance of a high mechanical Qf product for entanglement creation and provide a quantitative statement on which magnitude of the Qf product is necessary for a successful realization of the scheme. We determine the optimal parameter regime for its operation and show it to work in current state-of-the-art systems.

description: The billiard systems within quadrics, playing the role of discrete analogues of geodesics on ellipsoids, are incorporated into the theory of integrable quad-graphs. An initial observation is that the Six-pointed star theorem, as the operational consistency for the billiard algebra, is equivalent to an integrabilty condition of a line congruence. A new notion of the double-reflection nets as a subclass of dual Darboux nets associated with pencils of quadrics is introduced, basic properies and several examples are presented. Corresponding Yang-Baxter maps, associated with pencils of quadrics are defined and discussed.

description: In this article, we consider a matrix exponential unbalanced panel data model that allows for (i) spillover effects using matrix exponential terms, (ii) unobserved heterogeneity across entities and time, and (iii) potential heteroscedasticity in the error terms across entities and time. We adopt a likelihood based direct estimation approach in which we jointly estimate the common parameters and fixed effects. To ensure that our estimator has the standard large sample properties, we show how the score functions should be suitably adjusted under both homoscedasticity and heteroscedasticity. We define our suggested estimator as the root of the adjusted score functions, and therefore our approach can be called the M-estimation approach. For inference, we suggest an analytical bias correction approach involving the sample counterpart and plug-in methods to consistently estimate the variance-covariance matrix of the suggested M-estimator. Through an extensive Monte Carlo study, we show that the suggested M-estimator has good finite sample properties. In an empirical application, we use our model to investigate the third country effects on the U.S. outward foreign direct investment (FDI) stock at the industry level.

description: Using an off-critical deformation of the identity of Duminil-Copin and Smirnov, we prove a relationship between half-plane surface critical exponents $γ_1$ and $γ_{11}$ as well as wedge critical exponents $γ_2(α)$ and $γ_{21}(α)$ and the exponent characterising the winding angle distribution of the O($n$) model in the half-plane, or more generally in a wedge of wedge-angle $α.$ We assume only the existence of these exponents and, for some values of $n,$ the conjectured value of the critical point. If we assume their values as predicted by conformal field theory, one gets complete agreement with the conjectured winding angle distribution, as obtained by CFT and Coulomb gas arguments. We also prove the exponent inequality $γ_1-γ_{11} \ge 1,$ and its extension $γ_2(α)-γ_{21}(α) \ge 1$ for the edge exponents. We provide conjectured values for all exponents for $n \in [-2,2).$

description: Widely used methods for analyzing missing data can be biased in small samples. To understand these biases, we evaluate in detail the situation where a small univariate normal sample, with values missing at random, is analyzed using either observed-data maximum likelihood (ML) or multiple imputation (MI). We evaluate two types of MI: the usual Bayesian approach, which we call posterior draw (PD) imputation, and a little-used alternative, which we call ML imputation, in which values are imputed conditionally on an ML estimate. We find that observed-data ML is more efficient and has lower mean squared error than either type of MI. Between the two types of MI, ML imputation is more efficient than PD imputation, and ML imputation also has less potential for bias in small samples. The bias and efficiency of PD imputation can be improved by a change of prior.

description: We present a detailed comparison between the well-known SPH code GADGET and the new moving-mesh code AREPO on a number of hydrodynamical test problems. Through a variety of numerical experiments we establish a clear link between test problems and systematic numerical effects seen in cosmological simulations of galaxy formation. Our tests demonstrate deficiencies of the SPH method in several sectors. These accuracy problems not only manifest themselves in idealized hydrodynamical tests, but also propagate to more realistic simulation setups of galaxy formation, ultimately affecting gas properties in the full cosmological framework, as highlighted in papers by Vogelsberger et al. (2011) and Keres et al. (2011). We find that an inadequate treatment of fluid instabilities in GADGET suppresses entropy generation by mixing, underestimates vorticity generation in curved shocks and prevents efficient gas stripping from infalling substructures. In idealized tests of inside-out disk formation, the convergence rate of gas disk sizes is much slower in GADGET due to spurious angular momentum transport. In simulations where we follow the interaction between a forming central disk and orbiting substructures in a halo, the final disk morphology is strikingly different. In AREPO, gas from infalling substructures is readily depleted and incorporated into the host halo atmosphere, facilitating the formation of an extended central disk. Conversely, gaseous sub-clumps are more coherent in GADGET simulations, morphologically transforming the disk as they impact it. The numerical artefacts of the SPH solver are particularly severe for poorly resolved flows, and thus inevitably affect cosmological simulations due to their hierarchical nature. Our numerical experiments clearly demonstrate that AREPO delivers a physically more reliable solution.

description: Recently, there has been much interest in the evolution of quantum particles on closed time-like curves (CTCs). However, such models typically assume point-like particles with only two degrees of freedom - a very questionable assumption given the relativistic setting of the problem. We show that it is possible to generalise the Deutsch model of CTCs to fields using the equivalent circuit formalism. We give examples for coherent, squeezed and single-photon states interacting with the CTC via a beamsplitter. The model is then generalised further to account for the smooth transition to normal quantum mechanics as the CTC becomes much smaller than the size of the modes interacting on it. In this limit, we find that the system behaves like a standard quantum mechanical feedback loop.

Exploring the relationship between research in Information Retrieval and Information Seeking Behavior, 1979-2008
Creators: name: Talal, Alhaji
Publisher: name: University of British Columbia
Year: 2012

description: Information Retrieval (IR) and Information Seeking Behavior (ISB) are fields of study which contribute to the process by which relevant information is identified and used. In order to understand how to design more effective and easy-to-use information retrieval systems, researchers from both fields have called for greater collaboration and interaction between them. The objective of this study is to explore and measure the development of the relationship between IR and ISB from 1979 to 2008 by examining how IR and ISB developed separately, how the relationship between them changed, and what factors governed that relationship. The 30-year period was divided into six five-year time slices and several bibliometric studies were conducted: a study of IR and ISB publications and citations, a study of the membership of conference committees, and a study of references from the syllabi of courses. In addition to quantitative evidence, qualitative evidence derived from the literature was used. The findings of this study show IR steadily moving from a young established field with a settled core of researchers to a mature field that is open to the changing perspectives and the influence of new research problems and challenges. ISB, on the other hand, started out as a small emerging field, appearing as a highly dynamic field that moved quickly to a cohesive and focused field of research. IR and ISB focused on their fundamental models, theories, and methods, while sharing common interest in investigating the topics “Library Automation” and “Evaluation”, in the first two time slices (1979-1988). The relationship between the fields grew stronger and they shared more authors, references, and sources that focused on bridging topics, such as “Information Seeking” and “Relevance”. The strongest collaboration and integration between IR and ISB occurred in the fourth time slice (1994-1998). This was followed by a decline in the number of common authors and references occurred in the last two time slices (1999-2008). However, there is a greater interest in investigating bridging topics, such as “Information Needs” and “Information Use”. Four factors governed the relationship between the fields: calls for change, topics, research venues, and technological advances.

description: We carried out a systematic analysis of time lags between X-ray energy bands in a large sample (32 sources) of unabsorbed, radio quiet active galactic nuclei (AGN), observed by XMM-Newton. The analysis of X-ray lags (up to the highest/shortest frequencies/time-scales), is performed in the Fourier-frequency domain, between energy bands where the soft excess (soft band) and the primary power law (hard band) dominate the emission. We report a total of 15 out of 32 sources displaying a high frequency soft lag in their light curves. All 15 are at a significance level exceeding 97 per cent and 11 are at a level exceeding 99 per cent. Of these soft lags, 7 have not been previously reported in the literature, thus this work significantly increases the number of known sources with a soft/negative lag. The characteristic time-scales of the soft/negative lag are relatively short (with typical frequencies and amplitudes of ν\sim 0.07-4 \times 10^{-3} Hz and τ\sim 10-600 s, respectively), and show a highly significant (\gsim 4σ) correlation with the black hole mass. The measured correlations indicate that soft lags are systematically shifted to lower frequencies and higher absolute amplitudes as the mass of the source increases. To first approximation, all the sources in the sample are consistent with having similar mass-scaled lag properties. These results strongly suggest the existence of a mass-scaling law for the soft/negative lag, that holds for AGN spanning a large range of masses (about 2.5 orders of magnitude), thus supporting the idea that soft lags originate in the innermost regions of AGN and are powerful tools for testing their physics and geometry.

Ildl factorizations for sparse skew-symmetric matrices
Creators: name: He, Shiwen
Publisher: name: University of British Columbia
Year: 2012

description: Our goal is to solve a sparse skew-symmetric linear system efficiently. We propose a slight modification to the Bunch LDL\T factorization with partial pivoting strategy for skew-symmetric matrices, which saves approximately one third of the overall number of swaps of rows and columns on average. We also develop a rook pivoting strategy for this LDL\T factorization in Crout order. We derive an incomplete LDL\T factorization based on the full LDL\T factorization, with both partial pivoting strategy and rook pivoting strategy. The incomplete factorization can be used as a preconditioner for Krylov subspace solvers. Various column versions of ILUTP factorizations are investigated. We show that the approach taken saves approximately half of the work and storage compared to standard ILU factorizations that do not exploit the structure of the matrix, and the rook pivoting strategy is often superior to the partial pivoting strategy, in particular when the matrix is ill-conditioned and the overall number of elements in the rows of the factors is restricted.

description: We present a new test of gravitational interactions at the r\sim(0.2-20)Mpc scale, around the virial radius of dark matter halos measured through cluster-galaxy lensing of maxBCG clusters from the Sloan Digital Sky Survey (SDSS). We employ predictions from self-consistent simulations of f(R) gravity to find an upper bound on the background field amplitude of f_R0<3.5x10^-3 at the 1D-marginalized 95% confidence level. As a model-independent assessment of the constraining power of cluster profiles measured through weak gravitational lensing, we also constrain the amplitude F_0 of a phenomenological modification based on the profile enhancement induced by f(R) gravity when not including effects from the increased cluster abundance in f(R). In both scenarios, dark-matter-only simulations of the concordance model corresponding to f_R0=0 and F_0=0 are consistent with the lensing measurements, i.e., at the 68% and 95% confidence level, respectively.

description: In this paper, we consider a matrix exponential unbalanced panel data model that allows for (i) spillover effects using matrix exponential terms, (ii) unobserved heterogeneity across entities and time, and (iii) potential heteroskedasticity in the error terms across entities and time. We adopt a likelihood based direct estimation approach in which we jointly estimate the common parameters and fixed effects. To ensure that our estimator has the standard large sample properties, we show how the score functions should be suitably adjusted under both homoskedasticity and heteroskedasticity. We define our suggested estimator as the root of the adjusted score functions, and therefore our approach can be called the M-estimation approach. For inference, we suggest an analytical bias correction approach involving the sample counterpart and plug-in methods to consistently estimate the variance-covariance matrix of the suggested M-estimator. Through an extensive Monte Carlo study, we show that the suggested M-estimator has good finite sample properties. In an empirical application, we use our model to investigate the third country effects on the US outward foreign direct investment (FDI) stock at the industry level.
Bianchi-V string cosmological model and late time acceleration

description: In the present work we have searched the existence of the late time acceleration of the universe with string fluid as source of matter in Bianchi V space-time. To get the deterministic solution, we choose the scale factor as increasing function of time that yields a time dependent deceleration parameter, representing a model which generates a transition of universe from early decelerating phase to recent accelerating phase. The study reveals that strings dominate the early universe and eventually disappear from the universe for sufficiently large times i. e. at present epoch. The same is observed by current astronomical observations. The physical behaviour of universe has been discussed in detail.

description: "Store-Operated Calcium Entry (SOCE) is a Ca2+ signal pathway that consists in the ability of cells to sense a decrease in endoplasmic reticulum luminal Ca2+ and induce Ca2+ entry across the plasma membrane. It relies on two key players: STIM proteins and ORAI channels. Lines of evidence reported Ca2+ homeostasis dysregulation and a crucial role of SOCE mechanism in the pathophysiology of rare muscular disorders (e.g., myopathies and dystrophies) as well as autoimmune diseases, thus making SOCE as a novel therapeutic target in these conditions. In this perspective, a copper-catalyzed azide-alkyne cycloaddition-based medicinal chemistry campaign led to the discovery of CIC-39, a negative modulator of SOCE, as the lead compound endowed with high selectivity over other Ca2+-permeable channels, a good pharmacokinetic profile and an excellent safety profile. Based on its efficacy in models of Tubular Aggregate Myopathy (TAM) and Duchenne Muscular Dystrophy (DMD), CIC-39 has received two orphan designations and is now being preclinically developed through a collaborative project between academia and industry. So far, the in vivo efficacy of CIC-39 has been demonstrated in adult mice using intraperitoneal minipumps. However, this delivery strategy is not feasible in younger animals, where early treatment is crucial due to the genetic nature of TAM and DMD. To address this issue, we developed a library of prodrugs as injectable oil depot formulations for SC administration. We identified prodrug 3 as the best compound in terms of hydrolytic stability in mouse plasma and log P value, as well as solubility in the selected oil-based vehicle. In view of the in vivo testing, we have planned a PK study of compound 3 in 2-week-old wild-type mice."

description: From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic follow up using the FLWO, SAAO, WIYN, CTIO, KPNO, Magellan, MMT and Gemini telescopes, and from archival SDSS spectroscopy. We classify the optical counterparts as 50% BLAGN, 16% NELG, 14% ALG, and 20% stars. We detect QSOs out to z~5.5 and galaxies out to z~3. We have compiled extensive photometry from X-ray to radio bands. Together with our spectroscopic information, this enables us to derive detailed SEDs for our extragalactic sources. We fit a variety of templates to determine bolometric luminosities, and to constrain AGN and starburst components where both are present. While ~58% of X-ray Seyferts require a starburst event to fit observed photometry only 26% of the X-ray QSO population appear to have some kind of star formation contribution. This is significantly lower than for the Seyferts, especially if we take into account torus contamination at z>1 where the majority of our X-ray QSOs lie. In addition, we observe a rapid drop of the percentage of starburst contribution as X-ray luminosity increases. This is consistent with the quenching of star formation by powerful QSOs, as predicted by the merger model, or with a time lag between the peak of star formation and QSO activity. We have tested the hypothesis that there should be a strong connection between X-ray obscuration and star-formation but we do not find any association between X-ray column density and star formation rate both in the general population or the star-forming X-ray Seyferts. Our large compilation also allows us to report here the identification of 81 XBONG, 78 z>3 X-ray sources and 8 Type-2 QSO candidates. Also we have identified the highest redshift (z=5.4135) X-ray selected QSO with optical spectroscopy.

description: El Teide es un volcán situado en la isla española de Tenerife, en Canarias. Cuenta con una altitud oficial de 3715 metros sobre el nivel del mar1 y 7500 metros sobre el lecho oceánico, siendo el pico más alto del país, el de cualquier tierra emergida del océano Atlántico y el tercer mayor volcán de la Tierra desde su base en el lecho oceánico, después del Mauna Kea y el Mauna Loa, ambos en Hawái.2 La altitud del Teide convierte además a la isla de Tenerife en la décima isla más alta del mundo. La última erupción del Teide se corresponde con las lavas negras que cubren el cono, y ha sido datada entre los siglos vii y x de nuestra era.34 El Teide forma parte del parque nacional homónimo, declarado Patrimonio de la Humanidad por la UNESCO el 28 de junio de 2007. Es además un espacio natural protegido en la categoría de monumento natural que encierra el complejo volcánico Teide-Pico Viejo, un gran estratovolcán de tipo vesubiano que se mantiene dormido desde la última erupción de las Narices del Teide ocurrida en 1798, aunque permanecen activas las fumarolas que emite regularmente desde su cráter. El Teide es considerado el monumento natural más emblemático del archipiélago canario.5 También es un gran atractivo turístico que cada año atrae a millones de personas.

New D1-D5-P geometries from string amplitudes

description: We derive the long range supergravity fields sourced by a D1-D5-P bound state from disk amplitudes for massless closed string emission. We suggest that since the parameter controlling the string perturbation expansion for this calculation decreases with distance from the bound state, the resulting asymptotic fields are valid even in the regime of parameters in which there is a classical black hole solution with the same charges. The supergravity fields differ from the black hole solution by multipole moments and are more general than those contained within known classes of solutions in the literature, whilst still preserving four supersymmetries. Our results support the conjecture that the black hole solution should be interpreted as a coarse-grained description rather than an exact description of the gravitational field sourced by D1-D5-P bound states in this regime of parameters.

From black holes to their progenitors: A full population study in measuring black hole binary parameters from ringdown signals

description: A perturbed black hole emits gravitational radiation, usually termed the ringdown signal, whose frequency and time-constant depends on the mass and spin of the black hole. I investigate the case of a binary black hole merger resulting from two initially non-spinning black holes of various mass ratios, in quasi-circular orbits. The observed ringdown signal will be determined, among other things, by the black hole's spin-axis orientation with respect to Earth, its sky position and polarization angle - parameters which can take any values in a particular observation. I have carried out a statistical analysis of the effect of these variables, focusing on detection and measurement of the multimode ringdown signals using the reformulated European LISA mission, Next Gravitational-Wave Observatory, NGO, the third generation ground-based observatory, Einstein Telescope and the advanced era detector, aLIGO. To the extent possible I have discussed the effect of these results on plausible event rates, as well as astrophysical implications concerning the formation and growth of supermassive and intermediate mass black holes.
