description: We present results from a high-resolution, cosmological, $Λ$CDM simulation of a group of field dwarf galaxies with the "superbubble" model for clustered SN feedback, accounting for thermal conduction and cold gas evaporation. The initial conditions and the galaxy formation physics, other than SN feedback, are the same as in Shen et al. (2014). The simulated luminous galaxies have blue colors, low star formation efficiencies and metallicities, and high cold gas content, reproducing the observed scaling relations of dwarfs in the Local Volume. Bursty star formation histories and superbubble-driven outflows lead to the formation of kpc-size DM cores when stellar masses reaches $M_{*} > 10^6$ $M_{\odot}$, similar to previous findings. However, the superbubble model appears more effective in destroying DM cusps than the previously adopted "blastwave" model, reflecting a higher coupling efficiency of SN energy with the ISM. On larger scale, superbubble-driven outflows have a more moderate impact: galaxies have higher gas content, more extended stellar disks, and a smaller metal-enriched region in the CGM. The two halos with $M_{vir} \sim 10^9$ $M_{\odot}$, which formed ultra-faint dwarf galaxies in Shen et al. (2014), remain dark due to the different impact of metal-enriched galactic winds from two nearby luminous galaxies. The column density distributions of H I, Si II, C IV and O VI are in agreement with recent observations of CGM around isolated dwarfs. While H I is ubiquitous with a covering fraction of unity within the CGM, Si II and C IV are less extended. O VI is more extended, but its mass is only 11% of the total CGM oxygen budget, as the diffuse CGM is highly ionised by the UVB. Superbubble feedback produces C IV and O VI an order of magnitude higher column densities than those with blastwave feedback. The CGM and DM cores are most sensitive probes of feedback mechanisms.

description: Human protection has been a high priority since the international community’s failure in the 1990s to respond adequately to instances of mass atrocities in Somalia, Rwanda and Bosnia. Consequently, two human protection norms were developed: the ‘Responsibility to Protect’ (R2P) and the ‘Protection of Civilians in armed conflict’ (POC). Implementation of human protection through R2P is still contested, with non-Western states claiming that the concept has been used by Western states to pursue their own agendas. Non-Western rising and regional powers like Brazil, China and South Africa have taken the lead in raising these concerns. This thesis explores how Brazil, China and South Africa attempt to reconcile questions of legitimacy surrounding the pursuit of human protection through R2P. Based on Antje Wiener’s Theory of Contestation, this thesis analyses discourse of both norms surrounding specific peace operations each country has been involved in and finds that Brazil, China and South Africa contest R2P using normative concepts from POC. Outlining this process builds on the notion that non-Western states have agency in norm contestation of global governance norms, showing that Brazil, China and South Africa strategically shape R2P not only to meet their own normative expectations of human protection, but also the expectations of the global South. Further, their contestation of human protection norms has flow-on effects to the norms of standardised procedures in peace operation mandates and operational components.

description: Parrondo's paradox arises in sequences of games in which a winning expectation may be obtained by playing the games in a random order, even though each game in the sequence may be lost when played individually. We present a suitable version of Parrondo's paradox in reliability theory involving two systems in series, the units of the first system being less reliable than those of the second. If the first system is modified so that the distributions of its new units are mixtures of the previous distributions with equal probabilities, then under suitable conditions the new system is shown to be more reliable than the second in the "usual stochastic order" sense.

description: R E S U M OA água é um recurso essencial para suprir as necessidades do ser humano, porém a elevação das temperaturas, vem tornando-a escassa em partes do mundo. A poluição dos mananciais, decorrente da falta de tratamento de esgotos, também é um fator que influencia na quantidade e qualidade da água disponibilizada. Diante dessa realidade, este estudo propôs desenvolver um mapeamento sistemático na literatura, a fim de analisar as publicações de artigos sobre reutilização de águas residuais para irrigação. A base de dados SCOPUS foi utilizada para realizar a pesquisa dos artigos, usando as palavras-chave: "Wastewater" ou "Graywater", "Irrigation", "Agriculture" e "Reuse". Os resultados apontaram que nos títulos das publicações as palavras-chave mais usadas, foram: “Irrigação”, “Águas residuais”, “Água recuperada” e “Irrigação agrícola” e das palavras-chave foram: “Águas residuais”, “Agricultura”, “Reúso de água”, “Irrigação” e “Reutilização de águas residuais”. Notou-se também que, de acordo com o número de publicações, os artigos encontrados são estudos atuais e que o ano de 2020 apresentou maior número de publicações. Diante do tema abordado, os Estados Unidos se destacaram dos demais países, por ter maior índice de publicação, 15% do total. A revista Science of the Total Environment apresentou maior quantitativo de artigos sobre o tema, 14% do total publicado. Os parâmetros de qualidade comumente estudados, foram: DQO (12%), Nitrogênio (10%), Condutividade (9%), Sólidos suspensos (9%), Fósforo (8%), pH (8%) e DBO (7%). O estudo mostrou que a técnica se apresenta como uma opção propícia para a destinação adequada de efluentes.Palavras-Chave: Escassez de água, Agricultura, Tratamento de efluentes.

description: Molecular D/H ratios are frequently used to probe the chemical past of Solar System volatiles. Yet it is unclear which parts of the Solar Nebula hosted an active deuterium fractionation chemistry. To address this question, we present 0".2-0".4 ALMA observations of DCO+ and DCN 2-1, 3-2 and 4-3 towards the nearby protoplanetary disk around TW Hya, taken as part of the TW Hya Rosetta Stone project, augmented with archival data. DCO+ is characterized by an excitation temperature of ~40 K across the 70 au radius pebble disk, indicative of emission from a warm, elevated molecular layer. Tentatively, DCN is present at even higher temperatures. Both DCO+ and DCN present substantial emission cavities in the inner disk, while in the outer disk the DCO+ and DCN morphologies diverge: most DCN emission originates from a narrow ring peaking around 30~au, with some additional diffuse DCN emission present at larger radii, while DCO+ is present in a broad structured ring that extends past the pebble disk. Based on parametric disk abundance models, these emission patterns can be explained by a near-constant DCN abundance exterior to the cavity, and an increasing DCO+ abundance with radius. There appears to be an active deuterium fractionation chemistry in multiple disk regions around TW Hya, but not in the cold planetesimal-forming midplane and in the inner disk. More observations are needed to explore whether deuterium fractionation is actually absent in these latter regions, and if its absence is a common feature, or something peculiar to the old TW Hya disk.

description: With exceptional electrical and mechanical properties and at the same time air-stability, layered MoSi2N4 has recently draw great attention. However, band structure engineering via strain and electric field, which is vital for practical applications, has not yet been explored. In this work, we show that the biaxial strain and external electric field are effective ways for the band gap engineering of bilayer MoSi$_2$N$_4$ and WSi$_2$N$_4$. It is found that strain can lead to indirect band gap to direct band gap transition. On the other hand, electric field can result in semiconductor to metal transition. Our study provides insights into the band structure engineering of bilayer MoSi$_2$N$_4$ and WSi$_2$N$_4$ and would pave the way for its future nanoelectronics and optoelectronics applications.

description: Using Greenwich and SOON sunspot group data during the period 1874 -- 2005, we find that the sums of the areas of the sunspot groups in $0^\circ$ -- $10^\circ$ latitude-interval of the Sun's northern hemisphere and in the time-interval, minus 1.35 year to plus 2.15 year from the time of the preceding minimum--and in the same latitude interval of the southern hemisphere but plus 1.0 year to plus 1.75 year from the time of the maximum--of a sunspot cycle are well correlating with the amplitude (maximum of the smoothed monthly sunspot number) of its immediate following cycle. Using this relationship it is possible to predict the amplitude of a sunspot cycle by about 9 -- 13 years in advance. We predicted $74 \pm 10$ for the amplitude of the upcoming cycle~24. Variations in solar meridional flows during solar cycles and 9 -- 16 year variations in solar equatorial rotation may be responsible for the aforementioned relationship.

description: Australian artist Christian Waller nee Yandell (1894-1954) created artworks that unified her aesthetic and spiritual values. The technical and expressive brilliance of her work across a range of art media - drawing, painting, illustration, printmaking, stained glass and mosaic - makes it worthy of focused scholarly attention. Important influences on her practice included Pre-Raphaelitism, Art Deco and the Celtic Revival. Her spirituality was informed by a range of orthodox and alternative systems of belief, including: Christianity, Theosophy, the Hermetic Order of the Golden Dawn and the international Peace Mission Movement. Acting as an emissary, she included personal symbols - especially the sun, the moon, stars and flowers - in her artworks to encourage spiritual contemplation. In this thesis, I argue that Waller harnessed the decorative and expressive potential of these movements - along with a commitment to Arts and Crafts values - to develop a personal set of symbols that expressed her sense of the spiritual. This encompassed the harmony of word, image and message, which underscored her work. It is for this reason that I locate Waller within the international discourse of spiritual art. Despite her remarkable talents across media and the distinctive quality of her art, Waller has always occupied a peripheral position within Australian art and art history. Even when she is included in significant books and exhibitions, most often it is in relation to her hand-printed book 'The Great Breath: A Book of Seven Designs' (1932) and her relationship with her husband, fellow artist Napier Waller. Key aims of this thesis are to highlight the breadth and depth of Waller's art practice and to demonstrate that she made important contributions to Australian art and to art that addresses the sacred.This thesis introduces a number of Waller's artworks, stories and personal ephemera into scholarship, making a comprehensive study of the artist possible for the first time. It makes a major contribution to scholarship on the artist, especially in relation to the spiritual values that underpinned her practice, as expressed in the key symbols that are identified. By extension, it contributes a more nuanced understanding of art produced between the First and Second World Wars to Australian art history and to scholarship on art that addresses the sacred.

description: The PHENIX Experiment at the Relativistic Heavy Ion Collider has conducted a survey of fluctuations in charged hadron multiplicity in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 22, 62, and 200 GeV. A universal power law scaling for multiplicity fluctuations expressed as $σ^2/μ^2$ is observed as a function of $N_{part}$ for all species studied that is independent of the transverse momentum range of the measurement. PHENIX has also measured transverse momentum correlation amplitudes in p+p, d+Au, and Au+Au collisions. At low transverse momentum, significant differences in the correlations between the baseline p+p and d+Au data and the Au+Au data are presented.

description: Flat bands play an important role in diffraction-free photonics and attract fundamental interest in many-body physics. Here we report the engineering of flat-band localization of collective excited states of atoms in Creutz superradiance lattices with tunable synthetic gauge fields. Magnitudes and phases of the lattice hopping coefficients can be independently tuned to control the state components of the flat band and the Aharonov-Bohm phases. We can selectively excite the flat band and control the flat-band localization with the synthetic gauge field. Our study provides a room-temperature platform for flat bands of atoms and holds promising applications in exploring correlated topological materials.

Conceptualising legitimacy, moral panics and performance enhancing drugs : Crisis? Whose crisis?

description: In the debate surrounding performance enhancing drugs (PEDs) in sport, academic investigation has focused mainly on why some individual athletes use PEDs while other actors refrain from doing so. In this thesis I adopt a broader social perspective and argue that the debate can be usefully reframed by considering how sports governing bodies (SGBs) maintain legitimacy and moral authority over their sporting communities. This highlights how various drug-related controversies and reports are associated with a crisis of legitimacy for SGBs. The thesis adopts a social constructionist perspective, using a modified'moral panic' framework based on the work of Goode and Ben-Yehuda. Situating legitimacy within this moral panic model reveals the'multifaceted' nature of legitimacy and the way doping debate reflects the interests of elite SGBs. At the same time, elite SGBs affected by the debate can use the media to resist other elite SGBs and impose their own interpretation of reality upon the situation. Using a grounded theoretical model, I examine whether the anti-doping debate is an example of a 'moral panic,' involving PED-using 'folk devils.' In the first part of this thesis I present a socio-historical examination of anti-doping policies and interactions between the International Olympic Committee (IOC), the World Anti-Doping Agency (WADA) and the Australian Football League (AFL). Multiple methods were used, including a review of media coverage, an online survey and follow-up interview with sporting participants. This multi-layered approach revealed how the creation of PED-using 'folk devils' challenges SGBs legitimacy, while also providing opportunities to restore perceptions of legitimacy. A quantitative e-Survey and follow-up interviews revealed that grassroots sporting participants in Australia accepted there was a crisis of legitimacy for SGBs, even if the perceived causes of this crisis varied. Using this multi-dimensional approach, I conclude that the debate surrounding PEDs provides an example of a moral panic engineered by elite SGBs, and particularly WADA, based on a concern with maintaining the moral authority and legitimacy to control the ever-widening global sporting community.

description: Is the universe computable? If yes, is it computationally a polynomial place? In standard quantum mechanics, which permits infinite parallelism and the infinitely precise specification of states, a negative answer to both questions is not ruled out. On the other hand, empirical evidence suggests that NP-complete problems are intractable in the physical world. Likewise, computational problems known to be algorithmically uncomputable do not seem to be computable by any physical means. We suggest that this close correspondence between the efficiency and power of abstract algorithms on the one hand, and physical computers on the other, finds a natural explanation if the universe is assumed to be algorithmic; that is, that physical reality is the product of discrete sub-physical information processing equivalent to the actions of a probabilistic Turing machine. This assumption can be reconciled with the observed exponentiality of quantum systems at microscopic scales, and the consequent possibility of implementing Shor's quantum polynomial time algorithm at that scale, provided the degree of superposition is intrinsically, finitely upper-bounded. If this bound is associated with the quantum-classical divide (the Heisenberg cut), a natural resolution to the quantum measurement problem arises. From this viewpoint, macroscopic classicality is an evidence that the universe is in BPP, and both questions raised above receive affirmative answers. A recently proposed computational model of quantum measurement, which relates the Heisenberg cut to the discreteness of Hilbert space, is briefly discussed. A connection to quantum gravity is noted. Our results are compatible with the philosophy that mathematical truths are independent of the laws of physics.

description: We study the radio properties of 706 sub-millimeter galaxies (SMGs) selected at 870$μ$m with the Atacama Large Millimeter Array from the SCUBA-2 Cosmology Legacy Survey map of the Ultra Deep Survey field. We detect 273 SMGs at $>4σ$ in deep Karl G. Jansky Very Large Array 1.4 GHz observations, of which a subset of 45 SMGs are additionally detected in 610 MHz Giant Metre-Wave Radio Telescope imaging. We quantify the far-infrared/radio correlation through parameter $q_\text{IR}$, defined as the logarithmic ratio of the far-infrared and radio luminosity, and include the radio-undetected SMGs through a stacking analysis. We determine a median $q_\text{IR} = 2.20\pm0.03$ for the full sample, independent of redshift, which places these $z\sim2.5$ dusty star-forming galaxies $0.44\pm0.04$ dex below the local correlation for both normal star-forming galaxies and local ultra-luminous infrared galaxies (ULIRGs). Both the lack of redshift-evolution and the offset from the local correlation are likely the result of the different physical conditions in high-redshift starburst galaxies, compared to local star-forming sources. We explain the offset through a combination of strong magnetic fields ($B\gtrsim0.2$mG), high interstellar medium (ISM) densities and additional radio emission generated by secondary cosmic rays. While local ULIRGs are likely to have similar magnetic field strengths, we find that their compactness, in combination with a higher ISM density compared to SMGs, naturally explains why local and high-redshift dusty star-forming galaxies follow a different far-infrared/radio correlation. Overall, our findings paint SMGs as a homogeneous population of galaxies, as illustrated by their tight and non-evolving far-infrared/radio correlation.

The operating and financial performance of privatized firms : an empirical investigation
Creators: name: Laurin, Claude
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this dissertation is to analyze the impact of privatization on a firm's operating and financial performance. In a first step, a theoretical discussion of the impact privatization can have on the effort provided by the manager operating the firm in the name of the owners is exposed. It is shown that shareholders acquiring a privatized State-Owned Enterprise can get an effort monitoring advantage over the government. If the government's objectives pursued through the ownership of a firm change from being socio-political to profit maximization, then this comparative monitoring advantage of shareholders explains the privatization decision. In the second part of the dissertation, several financial aspects of share issue privatization are analyzed. Models developed for the Initial Public Offering (IPO) market are re-assessed in light of privatization particularities. It is argued that capital market limitations rather than a desire to signal good future prospects explains the fraction of ownership retained by the government in a share issue privatization (SIP). Uncertainty with respect to the future prospects of privatized firms along with a desire to insure the success of privatization share issues explains the underpricing of SIPs. Finally, unlike portfolio of IPOs, a portfolio formed of privatized firms is hypothesized to be not systematically outperformed by the market portfolio or by a portfolio composed of firms similar to the privatized firms. The empirical implications of the discussion which focus on the financial aspect of privatization are tested on a set of state-owned enterprises which were privatized between 1980 and 1995. The results of the tests are generally consistent with the predictions.

description: The earth texture with complex morphological geometry and compositions such as shale and carbonate rocks, is typically characterized with sparse field samples because of an expensive and time-consuming characterization process. Accordingly, generating arbitrary large size of the geological texture with similar topological structures at a low computation cost has become one of the key tasks for realistic geomaterial reconstruction. Recently, generative adversarial neural networks (GANs) have demonstrated a potential of synthesizing input textural images and creating equiprobable geomaterial images. However, the texture synthesis with the GANs framework is often limited by the computational cost and scalability of the output texture size. In this study, we proposed a spatially assembled GANs (SAGANs) that can generate output images of an arbitrary large size regardless of the size of training images with computational efficiency. The performance of the SAGANs was evaluated with two and three dimensional (2D and 3D) rock image samples widely used in geostatistical reconstruction of the earth texture. We demonstrate SAGANs can generate the arbitrary large size of statistical realizations with connectivity and structural properties similar to training images, and also can generate a variety of realizations even on a single training image. In addition, the computational time was significantly improved compared to standard GANs frameworks.

description: The Noninsured Crop Disaster Assistance Program (NAP) was established in 1994 and administered by USDA’s Farm Service Agency (FSA).  NAP is a risk management tool for those producers growing crops not currently covered by a crop insurance product.  The 2014 Farm Bill reauthorized NAP and made some dramatic changes to the program. NAP now offers coverage from the 50-percent level to the 65-percent level with producers able to buy-up coverage in 5-percent
increments at up to 100 percent of the established market price. Prior to the 2014 Farm Bill, NAP had only allowed coverage at the 50-percent level and 55 percent of the established market price of the crop.

description: The one-way measurement model is a framework for universal quantum computation, in which algorithms are partially described by a graph G of entanglement relations on a collection of qubits. A sufficient condition for an algorithm to perform a unitary embedding between two Hilbert spaces is for the graph G, together with input/output vertices I, O \subset V(G), to have a flow in the sense introduced by Danos and Kashefi [quant-ph/0506062]. For the special case of |I| = |O|, using a graph-theoretic characterization, I show that such flows are unique when they exist. This leads to an efficient algorithm for finding flows, by a reduction to solved problems in graph theory.

We also investigate the behavior of the complex resonance positions at the small opening limit. At the large $n$ limit, the real part of complex resonance positions approaches the solutions with different $m$ of Dirichlet problem with a scale $n^{-2}$ and the imaginary part goes zero as $n^{-2m}$ for TM and $n^{-2(m+1)}$ for TE polarization, where $m$ is the order of the resonance.

This study conducts a comparative analysis on low-rank matrix approximation methods in thermography with applications of semi-, convex-, and sparse- non-negative matrix factorization (NMF) methods for detecting subsurface thermal patterns. These methods inherit the advantages of principal component thermography (PCT) and sparse PCT, whereas tackle negative bases in sparse PCT with non-negative constraints, and exhibit clustering property in processing data. The practicality and efficiency of these methods are demonstrated by the experimental results for subsurface defect detection in three specimens (for different depth and size defects) and preserving thermal heterogeneity for distinguishing breast abnormality in breast cancer screening dataset (accuracy of 74.1%, 75.8%, and 77.8%).

description: This thesis explores a new approach to writing the environmental history of settler societies through an explicit focus on ecological processes, as distinct from the more commonly used landscape or geographic units. In this case, I focus upon the hydrological cycle and four key processes that constitute it. The processes are precipitation; flow above and below ground in rivers, creeks and aquifers; stored or still water in lakes, ponds and wetlands; and evaporation. The work examines the impact of the ecological processes that make up the hydrological cycle within the context of the daily life of colonial settlers in the catchment of the Gippsland Lakes in south eastern Victoria, Australia, from the commencement of white colonization in the late 1830s up to the turn of the century. This time period was selected because by 1900, the principal changes which laid the foundation for the Lakes seriously compromised ecological health in the late 1980s and early 1990s were all in place. Inspired by gestalt psychology, it examines the interaction of those processes with settler knowledge of biophysical processes, their religious and cultural beliefs, economic and political forces at work in their world, work and leisure time, their language and expressions, values and aspirations for themselves and their families. Each of these aspects informed their perceptions of the ecology around them, and particularly, their perception of the significance of water. The findings confirms the critical importance of cultural values, generated through myth, story and action, to understanding environmental changes. Colonial Gippslanders were committed to: a belief in progress, or alternately, banishing wilderness; a belief that the world was made by God for human benefit; and the desire for certainty versus the actual uncertainty in hydrological conditions. Collectively, colonial Gippslanders believed in progress as much as they believed in God, believed themselves largely separate from nature and plumped for certainty. They set to re-plumbing the catchment to eliminate, as far as possible within their technical capabilities, the natural variations within the hydrological cycle. The tools which they applied to achieve this radical re{u00AD}plumbing included the application of engineering knowledge, supported by increasing amounts of technology and machinery and by sophisticated socio{u00AD}political lobbying.

description: We consider winding conserving four point functions in the SL(2,R) WZW model for states in arbitrary spectral flow sectors. We compute the leading order contribution to the expansion of the amplitudes in powers of the cross ratio of the four points on the worldsheet, both in the m- and x-basis, with at least one state in the spectral flow image of the highest weight discrete representation. We also perform certain consistency check on the winding conserving three point functions.

description: We present measurements of the size of the quasar proximity zone ($R_p$) for eleven low-luminosity ($-26.16\leq M_{1450}\leq-22.83$) quasars at $z\sim6$, discovered by the Subaru High-$z$ Exploration of Low-Luminosity Quasars project (SHELLQs). Our faint quasar sample expands the $R_p$ measurement down to $M_{1450}=-22.83$ mag, where more common quasar populations dominate at the epoch. We restrict the sample to quasars whose systemic redshifts have been precisely measured by [CII] 158 $μ$m or MgII $λ$2798 emission lines. We also update the $R_p$ measurements for 26 luminous quasars presented in Eilers et al. (2017)(arXiv:1703.02539) by using the latest systemic redshift results. The luminosity dependence on $R_p$ is found to be consistent with the theoretical prediction assuming highly ionized intergalactic medium. We find a shallow redshift evolution of the luminosity-corrected $R_p$, $R_{p,{\rm corr}}^{-25}$ ($R_{p, \rm corr}^{-25}\propto(1+z)^{-3.79\pm1.72}$) over $5.8\lesssim z \lesssim6.6$. This trend is steeper than that of Eilers et al. (2017) but significantly shallower than those of the earlier studies. Our results suggest that $R_{p,\rm corr}$ is insensitive to the neutral fraction of the universe at $z\sim6$. Four quasars show exceptionally small $R_{p,\rm corr}^{-25}$ ($ \lesssim0.90$ proper Mpc), which could be the result of their young age ($<10^4$ yr) in the reionization epoch, though statistics is still small.

description: Passage Retrieval has traditionally relied on lexical methods like TF-IDF and BM25. Recently, some neural network models have surpassed these methods in performance. However, these models face challenges, such as the need for large annotated datasets and adapting to new domains. This paper presents a winning solution to the Poleval 2023 Task 3: Passage Retrieval challenge, which involves retrieving passages of Polish texts in three domains: trivia, legal, and customer support. However, only the trivia domain was used for training and development data. The method used the OKAPI BM25 algorithm to retrieve documents and an ensemble of publicly available multilingual Cross Encoders for Reranking. Fine-tuning the reranker models slightly improved performance but only in the training domain, while it worsened in other domains.

description: We study the critical points of the black hole scalar potential $V_{BH}$ in N=2, d=4 supergravity coupled to $n_{V}$ vector multiplets, in an asymptotically flat extremal black hole background described by a 2(n_{V}+1)-dimensional dyonic charge vector and (complex) scalar fields which are coordinates of a special Kähler manifold. For the case of homogeneous symmetric spaces, we find three general classes of regular attractor solutions with non-vanishing Bekenstein-Hawking entropy. They correspond to three (inequivalent) classes of orbits of the charge vector, which is in a 2(n_{V}+1)-dimensional representation $R_{V}$ of the U-duality group. Such orbits are non-degenerate, namely they have non-vanishing quartic invariant (for rank-3 spaces). Other than the 1/2-BPS one, there are two other distinct non-BPS classes of charge orbits, one of which has vanishing central charge. The three species of solutions to the N=2 extremal black hole attractor equations give rise to different mass spectra of the scalar fluctuations, whose pattern can be inferred by using invariance properties of the critical points of $V_{BH}$ and some group theoretical considerations on homogeneous symmetric special Kähler geometry.

Momentum-Dependent Local Ansatz Approach to the Metallic Ferromagnetism

description: The first principles momentum dependent local ansatz wavefunction method (MLA) has been extended to the ferromagnetic state by introducing spin-dependent variational parameters. The theory is applied to the ferromagnetic Fe, Co, and Ni. It is shown that the MLA yields the magnetizations being comparable to the results obtained by the GGA (generalized gradient approximation) in the density functional theory. The projected momentum distribution functions as well as the mass enhancement factors are also calculated on the same footing, and are compared with those in the paramagnetic state. It is shown that the calculated mass enhancement factor of Fe is strongly suppressed by the spin polarization due to exchange splitting of the e${}_{\rm g}$ flat bands, while those of Co and Ni remain unchanged by the polarization. These results are shown to be consistent with the experimental results obtained from the low-temperature specific heats.

description: Supernova remnant (SNR) shocks provide favourable sites of cosmic ray (CR) proton acceleration if the local magnetic field direction is quasi-parallel to the shock normal. Using the moving-mesh magneto-hydrodynamical (MHD) code AREPO we present a suite of SNR simulations with CR acceleration in the Sedov-Taylor phase that combine different magnetic field topologies, density distributions with gradients and large-scale fluctuations, and -- for our core-collapse SNRs -- a multi-phase interstellar medium with dense clumps with a contrast of $10^4$. Assuming the hadronic gamma-ray emission model for the TeV gamma-ray emission, we find that large-amplitude density fluctuations of $δρ/ρ_0\gtrsim75$ per cent are required to strongly modulate the gamma-ray emissivity in a straw man's model in which the acceleration efficiency is independent of magnetic obliquity. However, this causes strong corrugations of the shock surface that are ruled out by gamma-ray observations. By contrast, magnetic obliquity-dependent acceleration can easily explain the observed variance in gamma-ray morphologies ranging from SN1006 (with a homogeneous magnetic field) to Vela Junior and RX J1713 (with a turbulent field) in a single model that derives from plasma particle-in-cell simulations. Our best-fit model for SN1006 has a large-scale density gradient of $ \nabla{n}\simeq 0.0034~\mathrm{cm}^{-3}~\mathrm{pc}^{-1} $ pointing from south-west to north-east and a magnetic inclination with the plane of the sky of $\lesssim10^\circ$. Our best-fit model for Vela Junior and RX J1713 adopts a combination of turbulent magnetic field and dense clumps to explain their TeV gamma-ray morphologies and moderate shock corrugations.
