description: FAR has improved anti-jamming performance over traditional pulse-Doppler radars under complex electromagnetic circumstances. To reconstruct the range-Doppler information in FAR, many compressed sensing (CS) methods including standard and block sparse recovery have been applied. In this paper, we study phase transitions of range-Doppler recovery in FAR using CS. In particular, we derive closed-form phase transition curves associated with block sparse recovery and complex Gaussian matrices, based on prior results of standard sparse recovery under real Gaussian matrices. We further approximate the obtained curves with elementary functions of radar and target parameters, facilitating practical applications of these curves. Our results indicate that block sparse recovery outperforms the standard counterpart when targets occupy more than one range cell, which are often referred to as extended targets. Simulations validate the availability of these curves and their approximations in FAR, which benefit the design of the radar parameters.

description: Neutron scattering studies on powder and single crystals have provided new evidences for unconventional magnetism in Cu2Te2O5Cl2. The compound is built from tetrahedral clusters of S=1/2 Cu2+ spins located on a tetragonal lattice. Magnetic ordering, emerging at TN=18.2 K, leads to a very complex multi-domain, most likely degenerate, ground state, which is characterized by an incommensurate (ICM) wave vector k ~ [0.15, 0.42,1/2]. The Cu2+ ions carry a magnetic moment of 0.67(1) mB/ Cu2+ at 1.5 K and form a four helices spin arrangement with two canted pairs within the tetrahedra. A domain redistribution is observed when a magnetic field is applied in the tetragonal plane (Hc≈0.5 T), but not for H||c up to 4 T. The excitation spectrum is characterized by two well-defined modes, one completely dispersionless at 6.0 meV, the other strongly dispersing to a gap of 2 meV. The reason for such complex ground state and spin excitations may be geometrical frustration of the Cu2+ spins within the tetrahedra, intra- and inter-tetrahedral couplings having similar strengths and strong Dzyaloshinski-Moriya anisotropy. Candidates for the dominant intra- and inter-tetrahedral interactions are proposed.

description: We discuss an inertial migration of oblate spheroids in a plane channel, where steady laminar flow is generated by a pressure gradient. Our lattice Boltzmann simulations show that spheroids orient in the flow, so that their minor axis coincides with the vorticity direction (a log-rolling motion). Interestingly, for spheroids of moderate aspect ratios, the equilibrium positions relative to the channel walls depend only on their equatorial radius $a$. By analysing the inertial lift force we argue that this force is proportional to $a^3b$, where $b$ is the polar radius, and conclude that the dimensionless lift coefficient of the oblate spheroid does not depend on $b$, and is equal to that of the sphere of radius $a$.

title: ‘With this face, can I take up space in the world?’: Embodied geographies of facial difference
Creators: name: Gillespie, Kerry
Publisher: name: University of Glasgow
Year: 2023

description: This PhD thesis investigates the everyday lived experience of the embodiment of facial difference/disfigurement. In collaboration with six organisations that each provide support to those living with facial difference – Alopecia UK, Cleft Lip and Palate Association, Face Equality International, Facial Palsy UK, ReMake Up, and The Psoriasis Association – the research employs a qualitative methodology to generate insight into the experience of living with a facial appearance that does not conform to geographically variable social and aesthetic norms. The methodology of the project involves an online qualitative survey (n=92 respondents) and remote qualitative interviews (n=26), carried out with individuals who self-identify as having a ‘facial difference’: any condition or characteristic that alters or impacts the appearance of the face (e.g., hair loss from eyebrows, facial paralysis, a facial birthmark). These participant testimonies evidence the existence and manifestation of a stigmatised politics of facial and bodily appearance, providing insight into the spatial – and, as I argue, disabling – consequences of facial difference. 

Engaging with scholarship across disciplines such as human geography, sociology, psychology, bioethics, and disability studies, the research theoretically situates the geography of facial difference within this interdisciplinary framework, paying particular attention to embodied and disability geographies. The empirical chapters of the thesis are then structured around four main points of departure. Firstly, I locate the human face as an interface between bodies and worlds, revealing the significance of facial appearance in everyday life. Secondly, I probe into the disabling spatialities of facial difference, documenting participant accounts of living with varying forms of facial difference/disfigurement and how these can (re)produce a politics of inclusion/exclusion. Thirdly, I make significant contributions to the field of emotional geographies, identifying how the embodiment of facial difference is wrought with complex emotions for the face-bearer, uncovering emotions such as shame, guilt, and loss. Finally, I critically analyse multiple forms of facial appearance intervention, from everyday cosmetics to surgical procedures. The thesis concludes by creatively troubling the limits of this particular research project and identifies future research avenues for a geography of facial difference, possibly informed by feminist, queer, and crip theories. The thesis therefore contributes to interdisciplinary scholarship on facial and bodily appearance and difference, making original contributions to debates about the embodying or ‘materialising’ of emotions and identities, the role of bodily difference in creating social geographies of exclusion, the contested politics of appearance and aesthetics, and the epistemic challenges arising from prioritising ‘voices’ of experience.

description: We propose to use the hadron number fluctuations in the limited momentum regions to study the evolution of initial flows in high energy nuclear collisions. In this method by a proper preparation of a collision sample the projectile and target initial flows are marked in fluctuations in the number of colliding nucleons. We discuss three limiting cases of the evolution of flows, transparency, mixing and reflection, and present for them quantitative predictions obtained within several models. Finally, we apply the method to the NA49 results on fluctuations of the negatively charged hadron multiplicity in Pb+Pb interactions at 158A GeV and conclude that the data favor a hydrodynamical model with a significant degree of mixing of the initial flows at the early stage of collisions.

description: The paper proves the existence of a subgame perfect Nash
equilibrium in a vertically differentiated duopoly with uncovered market, for a large set of symmetric and asymmetric distributions of consumers, including, among others, all logconcave distributions. The proof relies on the ’income share elasticity’ representation of the consumers’ density function, which ensures the analytical tractability of the firms’ optimality conditions at a high level of generality. Some illustrative examples of the solution are offered, in order to assess the impact of distributive shocks on the equilibrium market configuration.

Era stato proprio un filosofo, del resto, ad avvertire ogni padrone che avrebbe dovuto considerarsi come un dipendente dei suoi stessi servitori. Ad ogni modo, da qualunque parte la si guardi, siamo oggi di fronte ad una distanza, ad un divorzio tra teologia e filosofia: un tempo coniugi, amanti, oggi separati, anche quando si trovano a dover convivere nella stessa casa.

The language of popular science from the printed page to the Web: The case of the Table of Contents

description: This paper offers a linguistic study within the domain of popular scientific discourse in the digital age. In particular, it is concerned with print and digital magazines and aims at investigating the process of ‘remediation’ from the printed page to the Web. More specifically, it focuses on headlines contained in the Table of Contents and argues that, when migrating from the page to the screen, they undergo a process of ‘intralingual’ translation. The paper seeks to demonstrate that the kind of shifts taking place show similarities to the linguistic-cultural changes occurring in ‘interlingual’ translation in the digital world.
The theoretical background is mainly linguistic and broadly informed by translation studies, but has links to journalism, new media and digital communication.
An empirical analysis of a corpus of headlines contained in National Geographic − in its print edition and online version − will be illustrated as a case in point. The final goal is to see whether language shifts could be related to (1) practical constraints of the digital medium, (2) issues of global communication and/or (3) needs to cope with the rhetoric of ‘immediacy’, ‘transparency’ and ‘plain speaking’ typical of the new media (cf. Cronin 2013).

Particolarmente in questi ultimi anni se ne sente in modo impellente la necessità. La questione religiosa è quotidianamente presente sulle prime pagine di tutti i giornali internazionali, ma spesso è affrontata con superficialità e senza il necessario approfondimento. La religione, quale essa sia e a qualsiasi latitudine si esprima, tocca in profondità la vita di miliardi di persone, ma in modo stupefacente la riflessione su di essa ha un andamento episodico e quasi residuale, abbandonata all’estro dei giornalisti e di opinionisti, che mancano spesso di una adeguata formazione storico-religiosa e filosofico-religiosa.

description: Introduction: 
Open fractures of the leg represent a severe trauma. The combined approach, shared between plastic and orthopaedic surgeons, is considered to be important, although this multidisciplinary treatment is not routinely performed. Aim of this study was to verify whether the orthoplastic treatment is of any advantage over the traditional simply orthopedic treatment, through a multicentric inclusion of these unfrequent injuries into a prospective study.

Material and methods: 
The following trauma centres were involved: Rizzoli Orthopaedic Institute/University of Bologna (leading centre) and Maggiore Hospital (Bologna, Italy), Frenchay Hospital (Bristol, United Kingdom), Jinnah Hospital (Lahore, Pakistan). All patients consecutively hospitalized in the mentioned centres between January 2012 and December 2013 due to tibial open fractures were included in the study and prospectively followed up to December 2014. Demographics and other clinical features were recorded, including the type of treatment (orthopaedic or orthoplastic). The considered outcome measures included duration of hospitalization, time for bone union and soft tissue closure, Enneking score at 3, 6 and 12 months, the incidence of osteomyelitis and other complications. 

Results:
A total of 164 patients were included in the study. Out of them 68% were treated with an orthoplastic approach, whereas 32% received a purely orthopedic treatment. All considered outcome measures showed to be improved by the orthoplastic approach, compared to the orthopaedic one: time for soft tissue closure (2 versus 25 weeks), duration of hospital stay (22 versus 55 days), time for bone union (6 versus 8.5 months) , number of additional operations (0.6 versus 1.2) and functional recovery of the limb at 12 months  (27 versus 19, Enneking’s score).  All results were statistically significant. 

Conclusion: 
The combined orthoplastic approach to the treatment of open tibia fractures, in particular for high grade injuries (Gustilo 3B), is proven to improve the outcome of these severe injuries.

description: We introduce driven exclusion processes with internal states that serve as generic transport models in various contexts, ranging from molecular or vehicular traffic on parallel lanes to spintronics. The ensuing non-equilibrium steady states are controllable by boundary as well as bulk rates. A striking polarization phenomenon accompanied by domain wall motion and delocalization is discovered within a mesoscopic scaling. We quantify this observation within an analytic description providing exact phase diagrams. Our results are confirmed by stochastic simulations.

Interdictions and benedictions : an analysis of AIDS prevention materials in Vancouver Canada
Creators: name: Egan, John Patrick
Publisher: name: University of British Columbia
Year: 2009

description: This study identifies differing interests which have impacted how Acquired Immune Deficiency Syndrome (AIDS) prevention programmes in Vancouver have evolved. Drawing largely upon the writings of Michel Foucault with respect to power, knowledge and sexuality, discursive trends in materials are identified, categorized and compared to consider how pertinent subjugated knowledges have developed. The interplay between knowledge-regimes (the benedicted) and subjugated knowledges (the interdicted) are explicated through textual analyses of the materials collected. The findings suggest that knowledges cultivated within the male homosexual communities of Vancouver ensured the implementation of prevention programmes contextually relevant to their own milieu. These strategies were also integrated into broader prevention initiatives designed for society in-general, once their efficacy was apparent. Implications for community education and public health education are discussed, and areas for future research are identified.

description: Let $μ_α$ be the Lebesgue plane measure on the unit disk with the radial weight $\frac{α+1}π(1-|z|^2)^α$. Denote by $\mathcal{A}^{2}_{n}$ the space of the $n$-analytic functions on the unit disk, square-integrable with respect to $μ_α$. Extending the results of Ramazanov (1999, 2002), we explain that disk polynomials (studied by Koornwinder in 1975 and Wünsche in 2005) form an orthonormal basis of $\mathcal{A}^{2}_{n}$. Using this basis, we provide the Fourier decomposition of $\mathcal{A}^{2}_{n}$ into the orthogonal sum of the subspaces associated with different frequencies. This leads to the decomposition of the von Neumann algebra of radial operators, acting in $\mathcal{A}^{2}_n$, into the direct sum of some matrix algebras. In other words, all radial operators are represented as matrix sequences. In particular, we represent in this form the Toeplitz operators with bounded radial symbols, acting in $\mathcal{A}^{2}_n$. Moreover, using ideas by Engliš (1996), we show that the set of all Toeplitz operators with bounded generating symbols is not weakly dense in $\mathcal{B}(\mathcal{A}^{2}_n)$.

By applying sinusoidally varying potentials to the electrodes, these minima can be made to move smoothly along the array. Polar molecules in low field seeking quantum states can be trapped in these traveling potential wells. This is experimentally demonstrated by transporting metastable CO molecules in 30 mK deep wells that move at constant velocities above the substrate.

description: The analysis of the Lyman-alpha forest of absorption lines in quasar spectra has emerged as a potentially powerful technique to constrain the linear matter power spectrum. In most previous work, the amplitude of the ionizing background was fixed by calibrating simulations to match the observed mean transmitted flux in the Lyman-alpha forest. This procedure is undesirable in principle as it requires the estimation of the unabsorbed quasar continuum level, a difficult undertaking subject to various sources of systematic error and bias. We suggest an alternative approach based on measuring the one-point probability distribution function (pdf) of the fluctuations in the flux about the mean, relative to the mean, i.e. the pdf of delta_f = (f - )/. This statistic, while sensitive to the amplitude of the ionizing background, has the virtue that its measurement does not require an estimate of the unabsorbed continuum level. We present a measurement of the pdf of delta_f from seven Keck HIRES spectra, spanning a redshift range of z = 2.2 - 4.4. To illustrate that our method is useful, we compare our measurements of the pdf of delta_f, and measurements of the flux power spectrum from Croft et al. (2002) at z = 2.72, with cosmological simulations. From this comparison, we obtain constraints on the mean transmission in the Lyman-alpha forest, the slope of the temperature-density relation, as well as the amplitude and slope of the mass power spectrum. Our methodology will be useful for obtaining more precise constraints with larger data samples from the Sloan Digital Sky Survey (SDSS).

Relevance of jet magnetic field structure for blazar axionlike particle searches

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Many theories beyond the Standard Model of particle physics predict the existence of axionlike particles (ALPs) that mix with photons in the presence of a magnetic field. One prominent indirect method of searching for ALPs is to look for irregularities in blazar gamma-ray spectra caused by ALP-photon mixing in astrophysical magnetic fields. This requires the modelling of magnetic fields between Earth and the blazar. So far, only very simple models for the magnetic field in the blazar jet have been used. Here we investigate the effects of more complicated jet magnetic field configurations on these spectral irregularities, by imposing a magnetic field structure model onto the jet model proposed by Potter & Cotter. We simulate gamma-ray spectra of Mrk 501 with ALPs and fit them to no-ALP spectra, scanning the ALP and B-field configuration parameter space and show that the jet can be an important mixing region, able to probe new ALP parameter space around $m_a\sim$ 1-1000 neV and $g_{aγ}\gtrsim$ $5\times10^{-12}$ GeV$^{-1}$. However, reasonable (i.e. consistent with observation) changes of the magnetic field structure can have a large effect on the mixing. For jets in highly magnetized clusters, mixing in the cluster can overpower mixing in the jet. This means that the current constraints using mixing in the Perseus cluster are still valid.

description: There are several applications which require high position resolution UV imaging. For these applications we have developed and successfully tested a new version of a 2D UV single photon imaging detector based on a microgap RPC. The main features of such a detectors is the high position resolution - 30 micron in digital form and the high quantum efficiency (1-8% in the spectral interval of 220-140 nm). Additionally, they are spark- protected and can operate without any feedback problems at high gains, close to a streamer mode. In attempts to extend the sensitivity of RPCs to longer wavelengths we have successfully tested the operation of the first sealed parallel-plate gaseous detectors with CsTe photocathodes. Finally, the comparison with other types of photosensitive detectors is given and possible fields of applications are identified.

description: To understand human evolution, archaeologists require precise chronologies to compare and contrast the fossil collection. While indirect dating techniques of human occupation sites usually applied on sediments are somehow more precise than direct dating techniques, the accuracy of indirect dating is frequently poor. Direct dating of human remains older than 50 to 60 ka (radiocarbon limit) is limited to U-series and ESR techniques. To minimize the impact of direct dating on valuable archaeological samples, non-destructive U-series and ESR analysis have to be carried out using specifically designed protocols. Both methods are seriously compromised by the fact that teeth accumulate large amounts of uranium following their deposition in sediments. During the three years of this PhD, a 2D mapping protocol has been developed on the isotope distributions and elemental concentrations of uranium and thorium in fossil teeth using laser ablation ICP-MS. Isotopic maps of enamel and dentine show complex patterns that imply that systematic mapping of fragments would provide accurate insight for U-series and ESR internal dose assessment. A fossil Neanderthal tooth from Payre (France) showed negligible U-migration through the external enamel surface compared to the internal migration from the dentine, with great implications for ESR dating. Non-destructive ESR analyses are carried out on enamel fragments instead of powders to minimize the impact of analysis on samples. Nevertheless, the ESR spectra of fragments have a high angular dependency which complicates their study and the establishment of experimental protocols. During this PhD, new measuring protocols and analytical decomposition of ESR spectra have allowed to gain new insight on the composite nature of the signal. The development of comprehensive model describing the influence of several oriented and non-oriented CO2- radicals in the spectra with complex kinetics and transfer processes has shown that major age underestimation can be expected for most fossil tooth enamel. The new model suggests that fossils such as the Irhoud specimen or Broken Hill had their age underestimated by around 30%, propelling the Irhoud specimen amongst the oldest anatomically modem humans in Africa.

description: A heavy scalar field such as moduli or an inflaton generally mixes with a field responsible for the supersymmetry breaking. We study the scalar decay into the standard model particles and their superpartners, gravitinos, and the supersymmetry breaking sector, particularly paying attention to decay modes that proceed via the mixing between the scalar and the supersymmetry breaking field. The impacts of the new decay processes on cosmological scenarios are also discussed; the modulus field generically produces too much gravitinos, and most of the inflation models tend to result in too high reheating temperature and/or gravitino overproduction.

Girl-to-girl bullying in early adolescence : beyond "bully", "victim", "bystander"
Creators: name: Fox, Katherine Anne
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this project was to ascertain young adolescent girls' conceptualizations of girl-to-girl bullying specifically during the transition year to secondary school. The literature reveals that bullying is high amongst girls at that time. In order to provide a background for understanding bullying, I analyzed some of the ways in which this type of aggression is contextualized in schools, their families, and their cultural communities, and include the girls' opinions of these shaping forces. I also examined the range of ways in which girls can be bullied by their female peers, giving attention to the girls' perceptions of the causes, conditions, and consequences of bullying. This small-scale exploratory field study took place in two urban secondary schools in one British Columbia Lower Mainland school district in the fall of 1993. Three ethnographic methods were used: participant observation; tape-recorded in-depth interviews with fifteen grade 8 and 9 girls; and researcher-solicited written narratives. Using those latter accounts, grade 9 Drama students created and performed short plays in the classroom on the theme of same-sex bullying. These skits provided additional insights into girls' definitions of bullying going on amongst them. The girls' friendships and peer groups provided the main context for inter-girl bullying incidents. Whereas most of the girls in this study employed the term "fighting" as an equivalent for bullying, I organize the wide range of hurtful behaviours they chronicled under three basic headings: betrayal, intimidation, and humiliation. The ways in which they carried out their aggressive acts were dependent on the various "weapons" at their disposal and the skill with which they deployed them. The evidence gleaned from this study suggests that existing definitions of bullying-traditionally grounded in male experiences-ought to be extended to include one-time incidents, verbal, physical, and attitudinal types of bullying that are specific to girls, and unintentional bullying of the joking kind. Of further note, I discovered that almost three-quarters of the girls I interviewed had played more than one bullying role, calling into question the usually mutually exclusive use of labels "bully", "victim", and "by-stander".

description: The persistent motility of the individual constituents in microbial suspensions represents a prime example of so-called active matter systems. Cells consume energy, exert forces and move, overall releasing the constraints of equilibrium statistical mechanics of passive elements and allowing for complex spatio-temporal patterns to emerge. Moreover, when subject to physico-chemical stimuli their collective behaviour often drives large scale instabilities of hydrodynamic nature, with implications for biomixing in natural environments and incipient industrial applications. In turn, our ability for external control of these driving stimuli could be used to govern the emerging patterns. Light, being easily manipulable and, at the same time, an important stimulus for a wide variety of microorganisms, is particularly well suited to this end. In this paper, we will discuss the current state, developments, and some of the emerging advances in the fundamentals and applications of light-induced bioconvection with a focus on recent experimental realisations and modelling efforts.

description: Background: The magnitude and duration of conditioned pain modulation (CPM) likely depends on the nature and intensity of the conditioning stimulus (CS). Aims: The aim of this study was to measure the effect of CS intensity on the duration of CPM hypoalgesia. Methods: In this single-blind, nonrandomized, repeated measures study, we assessed CPM hypoalgesia in 20 healthy participants following cold pressor tests (CPT) at 7°C and 12°C. The test stimulus, a 60-s heat stimulation, was administered before the CPT and immediately after, and again at 5-min intervals until participants’ pain scores returned to pre-CS levels. Two hypoalgesia thresholds were used to establish return to pre-CS level: within −10/100 of baseline and within −20/100 of baseline. Results: CPM hypoalgesia, when defined as a reduction in pain levels >10/100, did not last longer following the more intense 7°C CPT compared to the 12°C CPT (32 min vs. 20 min, respectively; P = 0.06); similar results were obtained when CPM hypoalgesia was defined as a reduction in pain levels of >20/100 (16 min following the 7°C CPT vs. 9 min following the 12°C CPT; P = 0.33). The duration of CPM hypoalgesia was significantly longer when the 10/100 threshold was used compared to the 20/100 threshold, regardless of CPT temperature (P = 0.008 for the 12°C CPT; P < 0.001 for the 7°C CPT). Conclusions: The more intense CS did not induce CPM hypoalgesia of longer duration compared to the less intense CS. The choice of threshold for what constitutes CPM hypoalgesia did have a significant effect on the results.

description: Intussusception is a common surgical disorder in dogs and cats commonly observed in puppies < 1 year of age and in adult intussusception is a rare condition. A 4-month-old intact male German shepherd dog was presented to Veterinary Clinical Complex, Kumarganj, Ayodhya with a history of anorexia, frequent vomition, diarrhoea and anal prolapse during straining from last one week. Symptomatic treatment for gastroenteritis was given by local vet but no response observed. Abdominal palpation revealed a relatively sausage shaped and tender mass in caudal abdomen. Plain radiographs have shown area of reduced serosal detail, gas accumulation at proximal to the obstruction site and of increased soft tissue density in the left of mid abdomen. The clinical history and physical examination were suggestive of intestinal intussusception. The intussusception was found at ileo-caeco-colic junction on laparotomy. Correction was done with by manual reduction or squeezing, Mild tear of muscularis layer was sutured with catgut 2-0 and entroplication was done.

description: We study noncommutative geometry at the Quantum Mechanics level by means of a model where noncommutativity of both configuration and momentum spaces is considered. We analyze how this model affects the problem of the two-dimensional gravitational quantum well and use the latest experimental results for the two lowest energy states of neutrons in the Earth's gravitational field to establish an upper bound on the fundamental momentum scale introduced by noncommutativity, namely $\sqrtη\lesssim1\ \mathrm{meV/c}$, a value that can be improved in the future by up to 3 orders of magnitude. We show that the configuration space noncommutativity has, in leading order, no effect on the problem. We also analyze some features introduced by the model, specially a correction to the presently accepted value of Planck's constant to 1 part in $10^{24}$.

description: Background: Chronic pain affects one in five persons and is a leading contributor to years lived with disability and high health care costs. In 2016, the government of Ontario increased public funding for pediatric and adult hospital-based interprofessional chronic pain clinics (HICPCs) in Ontario, Canada, expanding the role of physiotherapy in chronic pain management in the province. This role has yet to be described in the literature. Aim: The aim of this study was to explore physiotherapy practice within HICPCs in Ontario. Methods: We conducted an interpretive description qualitative study based on semistructured interviews with physiotherapists employed in pediatric and adult HICPCs in Ontario. Interviews were audio recorded, transcribed verbatim, and reviewed for accuracy. We analyzed interview data using thematic analysis. Results: Ten physiotherapists who practiced in pediatric and adult HICPCs (n = 4 pediatric; n = 6 adult) in Ontario were interviewed between February and April 2020. We constructed five themes related to physiotherapy practice in this setting. Themes included (1) contributing a functional lens to care; (2) empowering through pain education; (3) facilitating participation in physical activity and exercise; (4) supporting engagement in self-management strategies; and (5) implementing a collaborative approach to whole-person care. Conclusions: Our results illuminate how physiotherapy practice within HICPCs in Ontario focuses on providing a collaborative and whole-person approach to care, with an emphasis on supporting patients to increase their functional capacity by promoting engagement in active chronic pain management strategies.
Evidence for Power-law tail of the Wealth Distribution in India

description: The higher-end tail of the wealth distribution in India is studied using recently published lists of the wealth of richest Indians between the years 2002-4. The resulting rank distribution seems to imply a power-law tail for the wealth distribution, with a Pareto exponent between 0.81 and 0.92 (depending on the year under analysis). This provides a comparison with previous studies of wealth distribution, which have all been confined to Western advanced capitalist economies. We conclude with a discussion on the appropriateness of multiplicative stochastic process as a model for asset accumulation, the relation between the wealth and income distributions (we estimate the Pareto exponent for the latter to be around 1.5 for India), as well as possible sources of error in measuring the Pareto exponent for wealth.

description: We resolve the host galaxies of seven gravitationally lensed quasars at redshift 1.5 to 2.8 using observations with the Atacama Large (sub-)Millimetre Array. Using a visibility-plane lens modelling technique, we create pixellated reconstructions of the dust morphology, and CO line morphology and kinematics. We find that the quasar hosts in our sample can be distinguished into two types: 1) galaxies characterised by clumpy, extended dust distributions ($R_{\rm eff}\sim2$ kpc) and mean star formation rate surface densities comparable to sub-mm-selected dusty star-forming galaxies ($Σ_{\rm SFR}\sim3$ M$_{\odot}$ yr$^{-1}$ kpc$^{-2}$); 2) galaxies that have sizes in dust emission similar to coeval passive galaxies and compact starbursts ($R_{\rm eff}\sim0.5$ kpc), with high mean star formation rate surface densities ($Σ_{\rm SFR}=$ 400$-$4500 M$_{\odot}$ yr$^{-1}$ kpc$^{-2}$) that may be Eddington-limited or super-Eddington. The small size of some quasar hosts suggests that we observe them at a stage in their transformation into compact spheroids, where a high density of dynamically unstable gas leads to efficient star formation and black hole accretion. For the one system where we probe the mass of the gas reservoir, we find a gas fraction of just $0.06 \pm 0.04$ and a depletion timescale of $50 \pm 40$ Myr, suggesting it is transitioning into quiescence. In general, we expect that the extreme level of star formation in the compact quasar host galaxies will rapidly exhaust their gas reservoirs and could quench with or without help from active galactic nuclei feedback.

description: We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the UV to the near-IR). A crucial improvement is that the effective temperature scale of the stars has recently been established as both accurate and precise through direct measurement of angular diameters obtained with stellar interferometers. We fit the colours as a function of effective temperature and metallicity, and derive colour estimates for the Sun in the Johnson/Cousins, Tycho, Stromgren, 2MASS and SDSS photometric systems. For (B-V)_Sun, we favour the ``red'' colour 0.64 versus the ``blue'' colour 0.62 of other recent papers, but both values are consistent within the errors; we ascribe the difference to the selection of Sun-like stars versus interpolation of wider colour-Teff-metallicity relations.
