Large classical universes emerging from quantum cosmology

subject: FOS: Physical sciences

description: It is generally believed that one cannot obtain a large Universe from quantum cosmological models without an inflationary phase in the classical expanding era because the typical size of the Universe after leaving the quantum regime should be around the Planck length, and the standard decelerated classical expansion after that is not sufficient to enlarge the Universe in the time available. For instance, in many quantum minisuperspace bouncing models studied in the literature, solutions where the Universe leave the quantum regime in the expanding phase with appropriate size have negligible probability amplitude with respect to solutions leaving this regime around the Planck length. In this paper, I present a general class of moving gaussian solutions of the Wheeler-DeWitt equation where the velocity of the wave in minisuperspace along the scale factor axis, which is the new large parameter introduced in order to circumvent the abovementioned problem, induces a large acceleration around the quantum bounce, forcing the Universe to leave the quantum regime sufficiently big to increase afterwards to the present size, without needing any classical inflationary phase in between, and with reasonable relative probability amplitudes with respect to models leaving the quantum regime around the Planck scale. Furthermore, linear perturbations around this background model are free of any transplanckian problem.

description: Mobile clients that consume and produce data are abundant in fog environments and low latency access to this data can only be achieved by storing it in their close physical proximity. To adapt data replication in fog data stores in an efficient manner and make client data available at the fog node that is closest to the client, the systems need to predict both client movement and pauses in data consumption. In this paper, we present variations of Markov model algorithms that can run on clients to increase the data availability while minimizing excess data. In a simulation, we find the availability of data at the closest node can be improved by 35% without incurring the storage and communication overheads of global replication.

Effetto della combinazione di cellule CD4+CD25+, cellule staminali emopoietiche CD34+e ATG nella prevenzione della risposta alloreattiva delle cellule T in vitro ed in vivo

description: Il trapianto delle cellule staminali emopoietiche umane CD34+ in combinazione con le cellule T regolatorie CD4+/CD25+ FoxP3+ (Tregs) potrebbe  prevenire  l'alloreattività verso le cellule staminali emopoietiche e ridurre il rischio di rigetto in trapianti allogenici HLA non correlati.
Per dimostrare questa ipotesi abbiamo messo in coltura le cellule CD34+ e le cellule CD4+/CD25+ isolate con metodica immunomagnetica (Miltnyi Biotec)da sangue periferico  non manipolato,sangue periferico mobilizzato con G-CSF o da Cordone ombelicale.
Gli esperimenti svolti in vitro, hanno evidenziato che le cellule Tregs arricchite, ottenute dalla stessa fonte delle cellule CD34+( autologhe), mostravano un effetto inibitorio maggiore sulle celulle T alloreattive, rispetto alle cellule Tregs ottenute da un donatore terzo(allogenico).Inoltre  l'attività immunosoppressoria delle Tregs era mantenuta dopo stimolazione con cellule CD34+ allogeniche e i Tregs non modificavano l'attività clonogenica delle cellule staminali CD34+. Avendo ottenuto  questi dati in vitro abbiamo trapiantato in topi NOD/SCID le cellule Tregs e le cellule CD34+ in rapporto 1:1 o 1:2 ed è stato osservato un normale attecchimento delle cellule staminali.
Incubando queste cellule con dosi fisiologiche di timoglobulina derivata da coniglio (nota molecola immunosopressoria) non veniva modificato il numero dei Tregs dopo 6 giorni di coltura. Dopo l'esposizione  alla Timoglobulina, inoltre, i Tregs mantenevano la loro attività soppressoria, aumentava l'espressione del recettore chemochinico CCR7, e venivano rilasciate diverse citochine principalmente l'interleuchina 10(IL-10). Tali dati dimostrano come sia le cellule tregs autologhe che quelle allogeniche potrebbero essere trapiantate insieme alle cellule staminali CD34+ dopo un regime preparatorio di terapia che include la timoglobulina. A tale scopo sono state eseguite selezioni di Tregs da aferesi di donatori sani mobilizzati con G-CSF su scala clinica utilizzando biglie immunomagnetiche Clinical grade (Miltenyi Biotec) e sono state confrontate 2 modalità di selezione con due o tre passaggi con o senza la deplezione dei monociti CD14+.Si è dimostrato così che è possibile selezionare un numero uguale di CD34+ e Tregs ,che con  la metodica che prevede la deplezione dei monociti si ottiene una popolazione di cellule Tregs più pura ( > 80%) e infine le applicazioni possibili di questi risultati includo: trapianto di cellule CD34+  del donatore insieme a cellule Tregs in trapianti aploidentici ; infusione of cellule tregs isolate da PBSC mobilizzati con G-nei casi di pazienti con  GVHD steroide-resistente; infusione di  G-Tregs  del donatore nei casi di rigetto di organo trapiantato da of  donatore ancora vivente.
Electrothermal characterization and nonlinear modelling of GaN transistors for telecommunication circuit design

Subjects: ING-INF/01 Elettronica

description: This thesis starts showing the main characteristics and application fields of the AlGaN/GaN HEMT technology, focusing on reliability aspects essentially due to the presence of low frequency dispersive phenomena which limit in several ways the microwave performance of this kind of devices. Based on an equivalent voltage approach, a new low frequency device model is presented where the dynamic nonlinearity of the trapping effect is taken into account for the first time allowing considerable improvements in the prediction of very important quantities for the design of power amplifier such as power added efficiency, dissipated power and internal device temperature. An innovative and low-cost measurement setup for the characterization of the device under low-frequency large-amplitude sinusoidal excitation is also presented. This setup allows the identification of the new low frequency model through suitable procedures explained in detail. 
In this thesis a new non-invasive empirical method for compact electrothermal modeling and thermal resistance extraction is also described. The new contribution of the proposed approach concerns the non linear dependence of the channel temperature on the dissipated power. This is very important for GaN devices since they are capable of operating at relatively high temperatures with high power densities and the dependence of the thermal resistance on the temperature is quite relevant.
Finally a novel method for the device thermal simulation is investigated: based on the analytical solution of the tree-dimensional heat equation, a Visual Basic program has been developed to estimate, in real time, the temperature distribution on the hottest surface of planar multilayer structures. The developed solver is particularly useful for peak temperature estimation at the design stage when critical decisions about circuit design and packaging have to be made. It facilitates the layout optimization and reliability improvement, allowing the correct choice of the device geometry and configuration to achieve the best possible thermal performance.

description: The 30 and 44 GHz Back End Modules (BEM) for the Planck Low Frequency Instrument are broadband receivers (20% relative bandwidth) working at room temperature. The signals coming from the Front End Module are amplified, band pass filtered and finally converted to DC by a detector diode. Each receiver has two identical branches following the differential scheme of the Planck radiometers. The BEM design is based on MMIC Low Noise Amplifiers using GaAs P-HEMT devices, microstrip filters and Schottky diode detectors. Their manufacturing development has included elegant breadboard prototypes and finally qualification and flight model units. Electrical, mechanical and environmental tests were carried out for the characterization and verification of the manufactured BEMs. A description of the 30 and 44 GHz Back End Modules of Planck-LFI radiometers is given, with details of the tests done to determine their electrical and environmental performances. The electrical performances of the 30 and 44 GHz Back End Modules: frequency response, effective bandwidth, equivalent noise temperature, 1/f noise and linearity are presented.

description: Recent kinetic simulations sparked a debate regarding the emission mechanism responsible for pulsed GeV $γ$-ray emission from pulsars. Some models invoke curvature radiation, while other models assume synchrotron radiation in the current-sheet. We interpret the curved spectrum of the Vela pulsar as seen by H.E.S.S. II (up to $\sim$100 GeV) and the $Fermi$ Large Area Telescope (LAT) to be the result of curvature radiation due to primary particles in the pulsar magnetosphere and current sheet. We present phase-resolved spectra and energy-dependent light curves using an extended slot gap and current sheet model, invoking a step function for the accelerating electric field as motivated by kinetic simulations. We include a refined calculation of the curvature radius of particle trajectories in the lab frame, impacting the particle transport, predicted light curves, and spectra. Our model reproduces the decrease of the flux of the first peak relative to the second one, evolution of the bridge emission, near-constant phase positions of peaks, and narrowing of pulses with increasing energy. We can explain the first of these trends because we find that the curvature radii of the particle trajectories in regions where the second $γ$-ray light curve peak originates are systematically larger than those associated with the first peak, implying that the spectral cutoff of the second peak is correspondingly larger. However, an unknown azimuthal dependence of the $E$-field as well as uncertainty in the precise spatial origin of the GeV emission, precludes a simplistic discrimination of emission mechanisms.

description: The production of two b-quark pairs is a prominent background for Higgs and New Physics searches in various extensions of the Standard Model. We present here the next-to-leading order QCD corrections to the quark induced subprocess using the GOLEM approach for the virtual corrections. We show that our result considerably improves the prediction and conclude that the inclusion of next-to-leading order effects is indispensable for reliable studies of four b-quark observables in hadronic collisions.

The targum (1971:Feb. 1 - 1971:Feb. 26)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1971

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Its onset occurs above a critical driving energy and it is accompanied by giant waves that constitute an acoustic analogue of the rogue waves that occasionally appear on the surface of the ocean. The theory of the phenomenon is developed and shown to be in good agreement with the experiments.

description: The hot gas in clusters of galaxies creates a distinctive spectral distortion in the cosmic microwave background (CMB) via the Sunyaev-Zel'dovich (SZ) effect. The spectral signature of the SZ can be used to measure the CMB temperature at cluster redshift ($T_{\rm CMB}(z)$) and to constrain the monopole of the y-type spectral distortion of the CMB spectrum. In this work, we start showing the measurements of $T_{\rm CMB}(z)$ for a sample extracted from the Second Catalog of galaxy clusters produced by Planck (PSZ2) and containing 75 clusters selected from CHEX-MATE. Then we show the forecasts for future CMB experiments about the constraints on the monopole of the y-type spectral distortion of the CMB spectrum via the spectrum of the SZE.

Gravitational redshift and other redshift-space distortions of the imaginary part of the power spectrum
Creators: name: McDonald, Patrick
Publisher: name: arXiv
Year: 2009
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: I extend the usual linear-theory formula for large-scale clustering in redshift-space to include gravitational redshift. The extra contribution to the standard galaxy power spectrum is suppressed by k_c^{-2}, where k_c=c k/a H (k is the wavevector, a the expansion factor, and H=\dot{a}/a), and is thus effectively limited to the few largest-scale modes and very difficult to detect; however, a correlation, \propto k_c^{-1}, is generated between the real and imaginary parts of the Fourier space density fields of two different types of galaxy, which would otherwise be zero, i.e., the cross-power spectrum has an imaginary part: P_{ab}(k,μ)/P(k)=(b_a+fμ^2)(b_b+fμ^2) -i(3Ω_m/2)(μ/k_c)(b_a-b_b)+\mathcal{O}(k_c^{-2}), where P(k) is the real-space mass-density power spectrum, b_i are the galaxy biases, μis the cosine of the angle between the wavevector and line of sight, and f=dlnD/dlna (D is the linear growth factor). The total signal-to-noise of measurements of this effect is not dominated by the largest scales -- it converges at k~0.05 h/Mpc. This gravitational redshift result is pedagogically interesting, but naive in that it is gauge dependent and there are other effects of similar form and size, related to the transformation between observable and proper coordinates. I include these effects, which add other contributions to the coefficient of μ/k_c, and add a μ^3/k_c term, but don't qualitatively change the picture. The leading source of noise in the measurement is galaxy shot-noise, not sample variance, so developments that allow higher S/N surveys can make this measurement powerful, although it would otherwise be only marginally detectable in a JDEM-scale survey.

description: A Machining Centre is nowadays a complex mechanical, electronic, electrical system
that needs integrated design capabilities which very often require a high time-consuming effort.
Numerical techniques for designing and dimensioning the machine structure and components
usually requires different knowledge according to the system that have to be designed. This Ph. D
Thesis is related about the efforts of the Authors to develop a system that allows to perform the
complete project of a new machine optimized in its dynamic behaviour. An integration of the
different systems developed, each of which respond to specific necessities of designer, is here
presented. In particular a dynamic analysis system, based on a lumped mass approach, that rapidly
allows to setup the drives of the machine and an Integrated Dynamic Simulation System, based on a
FEM approach, that permit a dynamic optimization, are shown. A multilevel Data Base, and an
operator interface module provide to complete the designing platform. The proposed approach
represents a significant step toward the virtual machining for the prediction of the quality of the
worked surface.

description: Phytochemicals are photoprotective compounds that prevent mutations involved in skin cancer and ageing. We studied protective activity of plant compounds against ultraviolet B (UVB) radiation induced skin erythema in albino BALB/c mice. The protective effect was quantified using narrow-band reflectance spectroscopy both in the presence and the absence of plant compounds. Among the studied compounds, five (apigenin, caffeic acid, epigallocatechin gallate (EGCG), kaempferol, and pinocembrin) inhibited UVB-induced skin erythema in mice; thus, they are promising for skin photoprotection. Erythema measurements of mice skin using narrow-band reflectance spectroscopy are valuable for the identification of photoprotective compounds.

description: The binomial Science & Technology (S & T) is inseparable. In this contribution are presented some general considerations on the question of the aspect and interrelationships of the Science, Technology, Government and Society, and the role of Non Equilibrium Statistical Mechanics that are present in the nowadays highly sophisticated technologies and industrial processes that contribute to the wealth and well being of world society. The evolution of the Non Equilibrium Statistical Mechanics is briefly described. In present days remarkable development of all the modern technology, essential for the welfare and progress of the global society, imposes an immense stress on basic Physics, and consequently on Non Equilibrium Statistical Mechanics, in situations like, for example: fluids with complex structures, electronics and photonics involving systems out of equilibrium, nano-technologies, low-dimensional systems, non-linear and ultrafast processes in semiconductors devices, and soft matter. It is shown that the Non Equilibrium Statistical Mechanics can deal, within a certain degree of triumph, with some these situations, namely: 1. nonconventional thermo-hydrodynamics; 2. ultrafast relaxation processes in semiconductors devices; 3. nonequilibrium Bose-Einstein-like condensations and coherent states; 4. low-dimensional semiconductors; 5. thermo-statistics of complex structured systems; 6. nonlinear higher-order thermo-hydrodynamics; and 7. nonlinear transport in semiconductors devices. These areas are of particular interest, at the scientific, technological and at the production line, and therefore of relevance for government and society, successfully analyzed in terms of the formalism of Non Equilibrium Statistical Mechanics.

description: Consumer food waste, like many environmental behaviours, takes place in private, and is not directly subject to social monitoring. Nevertheless, social interactions can affect private opinions and behaviours. This paper builds an agent-based model of interactions between consumers heterogeneous in their sociability, initial opinions and behaviours related to food waste and willingness to consider different opinions, in order to assess how social interactions can affect private behaviours. Compared to existing models of opinion dynamics, we innovate by including a range of ``cognitive dissonance'' between stated opinions and actual behaviours that consumers are willing to accept before changing one of the two. We calibrate the model using questionnaire data on household food waste in Italy. We find that a limited degree of mixing between different socio-demographic groups, namely adult and young consumers, is enough to trigger change, but a certain openness of mind is required from more wasteful individuals. Equally, a small group of environmentally committed consumers can attract a sizeable share of the population towards low-waste behaviours if they show a certain variability of opinions and are willing to compromise with individuals in their close neighbourhood in terms of opinions. These findings can help design effective interventions to promote pro-environmental behaviours, taking advantage of the beneficial network effects while anticipating negative externalities.

Creep and damage models for the service behaviour of structural members

Subjects: ICAR/09 Tecnica delle costruzioni

description: Deformability is often a crucial to the conception of many civil-engineering structural elements.
Also, design is all the more burdensome if both long- and short-term deformability has to be
considered. In this thesis, long- and short-term deformability has been studied from the material
and the structural modelling point of view. Moreover, two materials have been handled: pultruded
composites and concrete.
A new finite element model for thin-walled beams has been introduced. As a main assumption,
cross-sections rigid are considered rigid in their plane; this hypothesis replaces that of the classical
beam theory of plane cross-sections in the deformed state. That also allows reducing the total
number of degrees of freedom, and therefore making analysis faster compared with twodimensional
finite elements. Longitudinal direction warping is left free, allowing describing
phenomena such as the shear lag. The new finite-element model has been first applied to concrete
thin-walled beams (such as roof high span girders or bridge girders) subject to instantaneous service
loadings. Concrete in his cracked state has been considered through a smeared crack model for
beams under bending.
At a second stage, the FE-model has been extended to the viscoelastic field and applied to pultruded
composite beams under sustained loadings. The generalized Maxwell model has been adopted.
As far as materials are concerned, long-term creep tests have been carried out on pultruded
specimens. Both tension and shear tests have been executed. Some specimen has been strengthened
with carbon fibre plies to reduce short- and long- term deformability. Tests have been done in a
climate room and specimens kept 2 years under constant load in time.
As for concrete, a model for tertiary creep has been proposed. The basic idea is to couple the
UMLV linear creep model with a damage model in order to describe nonlinearity. An effective
strain tensor, weighting the total and the elasto-damaged strain tensors, controls damage evolution
through the damage loading function. Creep strains are related to the effective stresses (defined by
damage models) and so associated to the intact material.

description: Impairment due to narcolepsy strongly limits job performance, but there are no standard criteria to
assess disability in people with narcolepsy and a scale of disease severity is still lacking. We
explored: 1. the interobserver reliability among Italian Medical Commissions making disability and
handicap benefit decisions for people with narcolepsy, searching for correlations between the
recognized disability degree and patients’ features; 2. the willingness to report patients to the
driving licence authority; 3. possible sources of variance in judgement. Fifteen narcoleptic patients
were examined by four Medical Commissions in simulated sessions. Raw agreement and
interobserver reliability among Commissions were calculated for disability and handicap benefit
decisions and for driving licence decisions. Levels of judgement differed on percentage of disability
(p<0.001), severity of handicap (p=0.0007) and the need to inform the driving licence authority
(p=0.032). Interobserver reliability ranged from Kappa = - 0.10 to Kappa = 0.35 for disability
benefit decision and from Kappa = - 0.26 to Kappa = 0.36 for handicap benefit decision. The raw
agreement on driving licence decision ranged from 73% to 100% (Kappa not calculable).
Spearman’s correlation between percentages of disability and patients’ features showed correlations
with age, daytime naps, sleepiness, cataplexy and quality of life. This first interobserver reliability
study on social benefit decisions for narcolepsy shows the difficulty of reaching an agreement in
this field, mainly due to variance in interpretation of the assessment criteria. The minimum set of
indicators of disease severity correlating with patients’ self assessments encourages a disability
classification of narcolepsy.

description: A high order, deterministic direct numerical method is proposed for the nonrelativistic $2D_{\bf x} \times 3D_{\bf v}$ Vlasov-Maxwell system, coupled with Fokker-Planck-Landau type operators. Such a system is devoted to the modelling of electronic transport and energy deposition in the general frame of Inertial Confinement Fusion applications. It describes the kinetics of plasma physics in the nonlocal thermodynamic equilibrium regime. Strong numerical constraints lead us to develop specific methods and approaches for validation, that might be used in other fields where couplings between equations, multiscale physics, and high dimensionality are involved. Parallelisation (MPI communication standard) and fast algorithms such as the multigrid method are employed, that make this direct approach be computationally affordable for simulations of hundreds of picoseconds, when dealing with configurations that present five dimensions in phase space.

description: Context: Determining the parameters of massive stars is crucial to understand many processes in galaxies and the Universe, since these objects are important sources of ionization, chemical enrichment and momentum. 10m class telescopes enable us to perform detailed quantitative spectroscopic analyses of massive stars in other galaxies, sampling areas of different metallicity. Relating the stars to their environment is crucial to understand the physical processes ruling their formation and evolution. Aims: In preparation for the GTC, our goal is to build a catalogue of massive star candidates in the metal-poor irregular galaxy IC1613 with high astrometric accuracy, apt for the current generation of multi-object spectrographs. A census of OB associations in this galaxy is also needed, to provide important additional information about age and environment of the candidate OB stars. Methods: From INT-WFC observations, we have built an astrometric and photometric catalogue of stars in IC1613. Candidate blue massive stars are preselected from their colors. A friends-of-friends algorithm is developed to find their clustering in the galaxy. While a common physical origin for all the members of the associations cannot be ensured, this is a necessary first step to place candidate OB stars in a population context. Results: We have produced a deep catalogue of targets in IC1613 that covers a large field of view. To achieve high astrometric accuracy a new astrometric procedure is developed for the INT-WFC data. We have also built a catalogue of OB associations in IC1613. We have found that they concentrate in the central regions, specially in the HII bubbles. The study of extinction confirms that it is patchy, with local values of color-excess above the foreground value.

Dynamics behind the quark mass hierarchy

description: We introduce a new class of models describing the quark mass hierarchy. In this class, the dynamics primarily responsible for electroweak symmetry breaking (EWSB) leads to the mass spectrum of quarks with no (or weak) isospin violation. Moreover, the values of these masses are of the order of the observed masses of the down-type quarks. Then, strong (although subcritical) horizontal diagonal interactions for the $t$ quark plus horizontal flavor-changing neutral interactions between different families lead (with no fine tuning) to a realistic quark mass spectrum. In this scenario, many composite Higgs bosons occur. A concrete model with the dynamical EWSB with the fourth family is described in detail.

description: Water supplies in arid regions have traditionally been assured by cisterns, channels, wells, among other man-made structures with smooth vertical walls that can be deadly traps for several animals, including amphibians and reptiles. In this study, we investigate the incidence of such “trap structures” on the herpetofauna of the eastern Iberian Peninsula. We explored which features of these structures and which biological traits are associated with higher incidence of falling into these traps. We studied 205 trap structures and found 1,224 amphibians or reptiles representing 25 different species, including endangered and protected ones. Broad-scale macroclimate and landscape variables were not associated with the incidence of traps. Instead, trap impact was influenced mainly by trap morphology and season of the year, which suggests that construction design and species phenology are the main factors to affect the incidence of a trap. Biological traits (subterranean or aquatic habits, diet, nocturnal activity or emission of reproductive calls) in some species were related to the probability of falling into these traps. Some species of snakes, lizards, and toads were more prone to fall in trap structures than other species. We conclude that trap structures can strongly impact amphibian and reptile survival, especially in arid or semi-arid regions where wells and water cisterns are widespread.

description: Providing uninterrupted response service is of paramount importance for emergency medical services, regardless of the operating scenario. Thus, reliable estimates of the time to the critical condition, under which there will be no available servers to respond the next incoming call, become very useful measures of the system's performance. In this contribution, we develop a key performance indicator by providing an explicit formula for the average time to the shortage condition. Our analytical expression for this average time is a function of the number of parallel servers and the inter-arrival and service times. We assume exponential distributions of times in our analytical expression but for evaluating the mean first-passage time to the critical condition under more realistic scenarios we validate our result through exhaustive simulations with lognormal service time distributions. For this task we have implemented an simulator in $R$. Our results indicate that our analytical formula is an acceptable approximation under any situation of practical interest.

Environment or Outflows? New insight into the origin of narrow associated QSO absorbers

description: Recent detailed studies of Narrow Absorption Line (NAL) systems in QSO-spectra have revealed that at least 50% of QSOs have NALs associated with the central engine, and in most cases they are found to be outflowing. Will studies of NALs provide the much sort after evidence for ubiquitous QSO feedback that can halt the formation of stars in galaxies? I present new results on the distribution of line-of-sight velocity offsets between MgII absorbers and their background QSOs, based on a large catalogue of absorbers from SDSS DR6 and greatly improved QSO-redshift estimates. My analysis reveals a high-velocity population of MgII NALs extending out to at least 6000 km/s from the QSOs, which cannot be ascribed to the clustering of local galaxies, similar to that observed recently for CIV absorbers. The very existence of such low ionisation gas clouds in the intense ionising field of the QSO suggests that we may indeed be witnessing the mechanical expulsion of gas, alongside the heating previously observed. I also show that there is a significant excess of low-velocity MgII NALs in radio-loud QSOs compared to radio-quiet QSOs. In the near future, improved QSO clustering results will allow us to say whether this is due to environmental or feedback effects.
