description: The surface flux (and the corresponding observed flux) of a geometrically thick ``funnel'' shaped disk is computed taking into account the radiation impinging on the surface from other parts of the disk. It is found that the ratio of the maximum apparent luminosity to the real luminosity of the disk is only a factor $\approx 5$ even when the opening angle of the disk is small ($\approx 15^o$). Thus, geometrically beamed emission from ``funnel'' shaped sub-Eddington disks around stellar mass black holes, cannot explain the Ultra-Luminous X-ray sources detected in nearby galaxies.

description: The transformation which adds (or removes) NUT charge when it is applied to electrovacuum, axisymmetric and stationary space-times is studied. After analysing the Ehlers and the Reina-Treves transformations we propose a new one, more precise in the presence of the Maxwell electromagnetic field. The enhanced Ehlers transformation proposed turns out to act as a gravitomagnetic duality, analogously to the electromagnetic duality, but for gravity: it rotates the mass charge into the gravomagnetic (or NUT) charge. As an example the Kerr-Newman-NUT black hole is obtained with the help of this enhanced transformation. Moreover a new analytical exact solution is built adding the NUT charge to a double charged black hole, at equilibrium. It describes the non-extremal generalisation of the Majumdar-Papapetrou-NUT solution. From the near-horizon analysis, its microscopic entropy, according to the Kerr/CFT correspondence, is found and the second law of black hole thermodynamics is discussed.

The mysterious HI deficiency of NGC 3175

description: Australia Telescope Compact Array HI observations reveal the existence of 5.8x10^8 M_sun of HI gas in the central 7 kpc of the edge-on spiral galaxy NGC 3175. The detected HI and CO gas can explain why star formation, as traced by other emission processes, is going on in the inner part of its disk. On the other hand, the entire outer disk, beyond 3.5 kpc radius, shows no HI emission, has a very red colour and exhibits neither radio continuum nor H-alpha emission. This indicates that the outer part of NGC 3175 is quiescent, i.e. not forming stars at a measurable rate. Its HI deficiency and the small extent of the HI layer, which is confined to the boundaries of the optically visible disk, make NGC 3175 a peculiar spiral galaxy. No intergalactic HI gas in the NGC 3175 group was detected in our interferometric observations. Earlier Parkes telescope single dish HI observations put an upper limit on the amount of diffuse gas that might have been missed by the interferometer at 2x10^8 M_sun. On DSS plates no galaxy in the NGC 3175 group of galaxies (Garcia 1993) is close enough to it and none exhibits disturbances that could indicate a close interaction which might have led to the stripping of large parts of its HI gas. Thus, despite an extensive multi-wavelength investigation, the reason for the unusual absence of HI and star formation activity in the outer disk of NGC 3175 remains an intriguing mystery.

The Star Formation History and the spatial distribution of stellar populations in the Ursa Minor Dwarf Spheroidal Galaxy

description: As a part of a project devoted to the study of the Ursa Minor dSph, the star formation history of the galaxy is presented in this paper. The analysis uses wide field photometry, encompassing about 1deg x 1deg (the total covered area being 0.75 deg^2), which samples the galaxy out to its tidal radius. Derivation of the SFH has been performed using the synthetic partial model technique. The resulting SFH shows that Ursa Minor hosts a predominantly old stellar population, with virtually all the stars formed earlier than 10 Gyr ago and 90% of them formed earlier than 13 Gyr ago. Nevertheless, Ursa Minor color-magnitude diagram shows several stars above the main, old turn-off forming a blue-plume (BP). If these stars were genuine, main-sequence stars, Ursa Minor would have maintained a low star formation rate extending up to 2 Gyr ago. However, several indications (relative amount and spatial distribution of BP stars and difficulty to retain processed gas) play against this possibility. In such context, the most reliable hypothesis is that BP stars are blue-stragglers originating in the old population, Ursa Minor hence remaining the only Milky Way dSph satellite to host a pure old stellar population. A marginally significant age gradient is detected, in the sense that stars in outer regions are slightly younger, in average. The distance of Ursa Minor, has been calculated using the magnitude of the horizontal-branch and a calibration based on Hipparcos data of main sequence sub-dwarfs. We estimated a distance d=76+/-4 Kpc, which is slightly larger than previous estimates. From the RGB color, we estimate a metallicity [Fe/H]=-1.9+/-0.2, in agreement with a previous spectroscopic determination. No metallicity gradients have been detected across the galaxy.

description: He purpose of the master's thesis is to record the main roles of Dermoscopy in the diagnosis of non-melanoma skin carcinoma (NMSC). We reviewed and analyzed the most widespread Dermoscopy practices and the ways they contribute to the diagnosis of NMSC, both Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC). Subsequently, we proceeded, through descriptive statistics and existing literature, to categorize these roles, from the medical staff to the European population. The most important of them emerged, as well as the clinical impact they have, during their application.

description: In 2020, conspiracies moved from the fringes of society, to the very center of socio-political life in the United States. In response, news sources have created an area of reporting called the misinformation beat. Covering conspiratorial content, however, poses unique epistemic challenges for journalists and researchers. One concern is that covering emerging conspiracy theories may inadvertently expose trusting readers to an especially seductive form of misinformation. Another concern is that savvy conspiracy theorists may be manipulating the media into unintentionally “spreading the word”. Given these dilemmas, this project seeks to quantify and qualify the coverage of conspiracy theories by digital news sources in the United States. The interaction between news and conspiratorial content is modeled through a computational content analysis and a network analysis of New York Times articles.

description: V697 Sco, the remnant of Nova Scorpii 1941 and currently at V ~ 20.0, is found from photometric observations to have the characteristics of an intermediate polar (IP) with an orbital period (Porb) of 4.49 h and a rotation period (Prot) of 3.31 h. It therefore appears to be a member of the rare class of IPs where Prot ~ Porb, which are probably discless systems. The prominence of the modulation at 0.5 Prot, and its orbital sidebands, indicates two-pole accretion.

Interfacial dynamics and pinch-off singularities for axially symmetric Darcy flow

description: We study a model for the evolution of an axially symmetric bubble of inviscid fluid in a homogeneous porous medium otherwise saturated with a viscous fluid. The model is a moving boundary problem that is a higher-dimensional analogue of Hele-Shaw flow. Here we are concerned with the development of pinch-off singularities characterised by a blow-up of the interface curvature and the bubble subsequently breaking up into two; these singularities do not occur in the corresponding two-dimensional Hele-Shaw problem. By applying a novel numerical scheme based on the level set method, we show that solutions to our problem can undergo pinch-off in various geometries. A similarity analysis suggests that the minimum radius behaves as a power law in time with exponent $α= 1/3$ just before and after pinch-off has occurred, regardless of the initial conditions; our numerical results support this prediction. Further, we apply our numerical scheme to simulate the time-dependent development and translation of axially symmetric Saffman-Taylor fingers and Taylor-Saffman bubbles in a cylindrical tube, highlighting key similarities and differences with the well-studied two-dimensional cases.

description: Several independent lines of evidence now point to a correlation between black hole mass, M_bh, and radio-luminosity. In this paper we discuss the correlation for quasars from the FIRST Bright Quasar Survey (FBQS), using black hole mass estimates from Hbeta linewidths. The FBQS objects fill in the gap between the radio-loud and radio-quiet quasars in the radio-luminosity - optical-luminosity plane, and we find that they fill the corresponding gap in the M_bh - radio luminosity correlation. There is thus a continuous variation of radio luminosity with M_bh, and no evidence for a ``switch'' at some set of critical parameter values which turns on powerful radio jets. By combining the FBQS data with that for quasars from the Palomar-Green survey we find evidence for a dependence of radio-luminosity on accretion rate relative to the Eddington limit, L/L_Edd, as well as on M_bh, consistent with the well-known radio-optical correlation for radio-loud quasars. We therefore suggest a new scheme to ``unify'' radio-loud and radio-quiet objects in which radio luminosity scales proportional to M_bh^{1.9+/-0.2}(L/L_Edd)^{1.0} for L/L_Edd~0.1, with an apparently weaker accretion rate dependence at low L/L_Edd. The scatter about this relation is +/-1.1 dex, and may well hide significant contributions from other physical effects, such as black hole spin and radio source environment.

description: Places undergoing transition where the built environment, changing economic value, and uncontrolled nature intersect are often rich in decay and growth. Predominantly fallow, ignored or discarded sites, they are contested locations. Edges, walls and fences in such places (with their associated openings and closed-off paths) are expressions of the marginal and are true ‘edgelands’. These places embody histories, and stories are implied when one takes an archaeologist’s eye to their details and traces. The ideas, marks, qualities, and relationships discovered in these locations are the subject matter for my work and are translated into the material form of the small wearable object. The visual outcomes of this research are expressed as collections of wearable objects that draw on a series of places in transition. This project also considers the function and role of wearable objects. The small crafted forms I have made are miniature works of art and also inherit the history of jewellery. As such, they are viewed in the studio or gallery and when worn, draw focus to a person. As static objects they embody ideas and feelings of a place, implying stories, but, on the body, are conceptually re-formed in a new set of relationships in time and space.

description: The Gaia hypothesis postulates that life regulates its environment to be favorable for its own survival. Most planets experience numerous perturbations throughout their lifetimes such as asteroid impacts, volcanism, and the evolution of their host star's luminosity. For the Gaia hypothesis to be viable, life must be able to keep the conditions of its host planet habitable, even in the face of these challenges. ExoGaia, a model created to investigate the Gaia hypothesis, has been previously used to demonstrate that a randomly mutating biosphere is in some cases capable of maintaining planetary habitability. However, those model scenarios assumed that all non-biological planetary parameters were static, neglecting the inevitable perturbations that real planets would experience. To see how life responds to climate perturbations to its host planet, we created three climate perturbations in ExoGaia: one rapid cooling of a planet and two heating events, one rapid and one gradual. The planets on which Gaian feedbacks emerge without climate perturbations are the same planets on which life is most likely to survive each of our perturbation scenarios. Biospheres experiencing gradual changes to the environment are able to survive changes of larger magnitude than those experiencing rapid perturbations, and the magnitude of change matters more than the sign. These findings suggest that if the Gaia hypothesis is correct, then typical perturbations that a planet would experience may be unlikely to disrupt Gaian systems.

description:
To date, theoretical and conceptual scholarship on anti-racism has been advanced through leading contributions from several disciplines (e.g., sociology, education, psychology). Still, there remain fewer empirical studies on anti-racism constructs, and we know little about the development of anti-racism among diverse youth across key stages of development. In this special section of Child Development, we sought to address this gap by highlighting scholarship in developmental science that attends to the development of anti-racism in children across contexts (e.g., families, schools) and developmental stages (e.g., early childhood through emerging adulthood). In our introduction to the special section, we review the collective contributions of included studies and outline recommendations for future research in the development of anti-racism in youth.

description: In low-mass disks, turbulent torques are probably the most important way of redistributing angular momentum. Here we present the theory of turbulent accretion disks. We show the molecular viscosity is far too small to account for the evolutionary timescale of disks, and we describe how turbulence may result in enhanced transport of (angular) momentum. We then turn to the magnetorotational instability, which thus far is the only mechanism that has been shown to initiate and sustain turbulence in disks. Finally, we present both the basis and the structure of alpha disk models.

description: Oxide heterostructures and superlattices have attracted a great deal of attention in recent years owing to the rich exotic properties encountered at their interfaces. We focus on the potential of tunable correlated oxides by investigating the spectral function of the prototypical correlated metal SrVO3, using soft x-ray absorption spectroscopy (XAS) and resonant inelastic soft x-ray scattering (RIXS) to access both unoccupied and occupied electronic states, respectively. We demonstrate a remarkable level of tunability in the spectral function of SrVO3 by varying its thickness within the SrVO3/SrTiO3 superlattice, showing that the effects of electron correlation can be tuned from dominating the energy spectrum in a strongly correlated Mott-Hubbard insulator, towards a correlated metal. We show that the effects of dimensionality on the correlated properties of SrVO3 are augmented by interlayer coupling, yielding a highly flexible correlated oxide that may be readily married with other oxide systems.

description: Two-dimensional (2D) van der Waals (vdW) materials show a range of profound physical properties that can be tailored through their incorporation in heterostructures and manipulated with external forces. The recent discovery of long-range ferromagnetic order down to atomic layers provides an additional degree of freedom in engineering 2D materials and their heterostructure devices for spintronics, valleytronics and magnetic tunnel junction switches. Here, using direct imaging by cryo-Lorentz transmission electron microscopy we show that topologically nontrivial magnetic-spin states, skyrmionic bubbles, can be realized in exfoliated insulating 2D vdW Cr2Ge2Te6. Due to the competition between dipolar interactions and uniaxial magnetic anisotropy, hexagonally-packed nanoscale bubble lattices emerge by field cooling with magnetic field applied along the out-of-plane direction. Despite a range of topological spin textures in stripe domains arising due to pair formation and annihilation of Bloch lines, bubble lattices with single chirality are prevalent. Our observation of topologically-nontrivial homochiral skyrmionic bubbles in exfoliated vdW materials provides a new avenue for novel quantum states in atomically-thin insulators for magneto-electronic and quantum devices.

Search for vector-like leptons in multilepton final states in proton-proton collisions at $\sqrt{s}$ = 13 TeV

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for vector-like leptons in multilepton final states is presented. The data sample corresponds to an integrated luminosity of 77.4 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC in 2016 and 2017. Events are categorized by the multiplicity of electrons, muons, and hadronically decaying $τ$ leptons. The missing transverse momentum and the scalar sum of the lepton transverse momenta are used to distinguish the signal from background. The observed results are consistent with the expectations from the standard model hypothesis. The existence of a vector-like lepton doublet, coupling to the third generation standard model leptons in the mass range of 120-790 GeV, is excluded at 95% confidence level. These are the most stringent limits yet on the production of a vector-like lepton doublet, coupling to the third generation standard model leptons.

description: One hundred and forty six long-period red variable stars in the Large Magellanic Cloud (LMC) from the three year MOA project database were analysed. A careful periodic analysis was performed on these stars and a catalogue of their magnitudes, colours, periods and amplitudes is presented. We convert our blue and red magnitudes to $K$ band values using 19 oxygen-rich stars. A group of red short-period stars separated from the Mira sequence has been found on a (log P, K) diagram. They are located at the short period side of the Mira sequence consistent with the work of Wood and Sebo (1996). There are two interpretations for such stars; a difference in pulsation mode or a difference in chemical composition. We investigated the properties of these stars together with their colour, amplitude and periodicity. We conclude that they have small amplitudes and less regular variability. They are likely to be higher mode pulsators. A large scatter has been also found on the long period side of the (log P, K) diagram. This is possibly a systematic spread given that the blue band of our photometric system covers both standard B and V bands and affects carbon-rich stars.

subject: co-create-build-engage

description: The ultimate purpose of social marketing is to improve the well-being of society, yet the effectiveness of social marketing programs to improve mental health and well-being has received limited attention. Moreover, a clear roadmap to co-create, implement, promote and evaluate theory-driven social marketing programs is absent. This thesis brings together the results of four studies, reported across four papers, documenting the co-creation and market testing of one well-being program – Elevate Self Growth. Study 1 details how four participatory design sessions underpinned the co-creation of the well-being program. Study 2 demonstrates how insights obtained in Study 1 were used to select and apply theory (Social Cognitive Theory) to the program creation. It also shows specifically how theory mapping led to the development of program components and presented an engagement plan that guided the program rollout. Study 3 presents a theoretically informed mixed method evaluation of the proof-of-concept well-being program. Finally, Study 4 assesses various promotional strategies to identify the optimal method to maximise engagement and uptake of the wellbeing program. Several processes were developed to further operationalise the co-createbuild-engage (CBE) framework, which delivers a guide that social marketers can apply to social marketing program co-creation, implementation, promotion, and evaluation. This thesis makes four major contributions. First, this research verified the efficacy of social marketing in changing well-being behaviour and improving well-being outcomes. Second, this thesis expanded on the CBE framework by providing operational guidance on each of the framework’s stages (co-create, build, engage). Third, this research advanced theory understanding by providing insights into the step-by-step process of selecting and applying a theory (SCT) in social marketing program design as well as testing and demonstrating early evidence for its effectiveness in improving well-being. Fourth, this research demonstrated the value of action research. Optimal marketing effectiveness may be achieved when people are involved early on and solutions are tested early and frequently to determine their potential for creating desired change. In conclusion, this research provides both academics and practitioners with the tools to better understand how to apply social marketing for the betterment of people and society at large.

description: We present new optical spectroscopy of the lens elliptical galax in the ``Einstein Cross'' lens system HST 14176+5226, using the Faint Object Camera and Spectrograph (FOCAS) of the Subaru t Our spectroscopic observations are aimed at measuring the stella dispersion of the lens galaxy, located at high redshift of z_L= as an important component to lens models. We have measured this 230 +- 14 km s^{-1} (1 sigma) inside 0.35 effective radi based on the comparison between the observed galaxy spectrum and templates of three G-K giants by means of the Fourier cross-corr To extract the significance of this information on the geometry universe which also affects the lensing of the background image, to fit three different lens models to the available data of the Provided that the lens galaxy has the structural and dynamical p (i.e., its radial density profile, core radius, and velocity ani similar to those of local elliptical galaxies, we calculate the function for the simultaneous reproduction of both the observed and newly measured velocity dispersion of the lens. Although the interval depends rather sensitively on the adopted lens models o parameters, our experiments suggest the larger likelihood for a cosmological constant, Omega_Lambda: formal 1 sigma lower Omega_Lambda in the flat universe ranges 0.73 to 0.97, where lower limit is basically unavailable. This method for determinin model is thus dependent on lens models but is insensitive to oth ambiguities, such as the dust absorption or the evolutionary eff galaxies. Exploring spectroscopic observations of more lens gala redshift may minimize the model uncertainties and thus place a m constraint on Omega_Lambda.
