Charge densities in stellar interiors: a step towards the understanding ofthe rotation–activity–age relationship for low-mass stars
Creators: name: Brito, Ana

Publisher: name: Zenodo
Year: 2023

description: Although space-based missions such as CoRoT, Kepler/K2, TESS, and the future data from the PLATO mission have provided a wealth of observational data, the connections between rotation, magnetic activity, and the thermodynamic properties of stellar interiors are still not well understood. To shed light on these connections and their implications for interpreting observational data, we study the internal distributions of net electric charge densities in a set of low-mass theoretical models (0.7 - 1.4 solar masses) with varying ages and metallicities, and explore their relationship with observable rotational trends on the main sequence. The amplitude scattering of charge densities exhibits substantial variation across orders of magnitude with respect to mass, age, and metallicity. Our research shows that models with lower mass have higher net charge density values through the radiative zones compared to models with higher mass. We also show that the properties of the charge evolve on the main sequence following a Skumanich--type relation. Furthermore, the amplitudes of net charges exhibit a sharp decline during the first half of the main sequence, which may be related to the weakened magnetic braking. Finally, we verified that high-metallicity stars have higher net charge amplitude values than low-metallicity stars, implying that high-metallicity values favor lower rotation rates as some recent studies indicate. Thus, our results show that the properties of net charge density distributions in stellar interiors can be associated with all major observational trends for the main-sequence rotation of low-mass stars.

description: Analyticity and unitarity techniques are employed to obtain bounds on the shape parameters of the scalar and vector form factors of semileptonic $K_{l3}$ decays. For this purpose we use vector and scalar correlators evaluated in pQCD, a low energy theorem for scalar form factor, lattice results for the ratio of kaon and pion decay constants, chiral perturbation theory calculations for the scalar form factor at the Callan-Treiman point and experimental information on the phase and modulus of $Kπ$ form factors up to an energy $\tin=1 {\rm GeV}^2$. We further derive regions on the real axis and in the complex-energy plane where the form factors cannot have zeros.

description: This study sought to better understand knowledge building as defined by Scardamalia and Bereiter (2003) as “the production and continual improvement of ideas of value to a community, through means that increase the likelihood that what the community accomplishes will be greater than the sum of individual contributions and part of broader cultural efforts” (p. 1370). This study, which was carried out in a grade three and four classroom, was bound by the following research question: What learning designs enable a class of students to engage in knowledge building? I employed practitioner action research as a methodological approach to examine, critically question, and transform my understandings of my practice, how I conduct my practice and the conditions under which I practice (Kemmis et al., 2014). Sources of evidence included samples of computer supported collaborative work, documents, observations and journals. Designs for knowledge building included the use of hooks to elicit real ideas and authentic questions from students, ongoing reference to knowledge building principles as defined by Scardamalia (2002), scaffolds to support student discourse, both face-to-face and online, and the use of Google Applications for Education (GAFE) as a networked space to support sharing and feedback for improving ideas. The outcomes of this research suggested that students did, with the support of scaffolds, engage with knowledge building principles, worked as a community to improve ideas of value to the community and used GAFE in support of the work of knowledge building. Findings of this study support an ongoing understanding of how both a teacher and a group of students new to knowledge building advance in their effort to continually improve ideas as a community. Recommendations for further research include: 1) how a culture for knowledge building might continue to shift in a classroom over time; 2) how those students with some experience in knowledge building might support those new to knowledge building; and 3) how the Social Infrastructure Framework (Bielaczyc, 2006, 2013) can support in the design for knowledge building.

description: The assessment of information flows is an essential part of analyzing Android apps, and is frequently supported by static taint analysis. Its precision, however, can suffer from the analysis not being able to precisely determine what elements a pointer can (and can not) point to. Recent advances in static analysis suggest that incorporating dynamic heap snapshots, taken at one point at runtime, can significantly improve general static analysis. In this paper, we investigate to what extent this also holds for taint analysis, and how various design decisions, such as when and how many snapshots are collected during execution, and how exactly they are used, impact soundness and precision. We have extended FlowDroid to incorporate heap snapshots, yielding our prototype Heapster, and evaluated it on DroidMacroBench, a novel benchmark comprising real-world Android apps that we also make available as an artifact. The results show (1) the use of heap snapshots lowers analysis time and memory consumption while increasing precision; (2) a very good trade-off between precision and recall is achieved by a mixed-mode in which the analysis falls back to static points-to relations for objects for which no dynamic data was recorded; and (3) while a single heap snapshot (ideally taken at the end of the execution)suffices to improve performance and precision, a better trade-off can be obtained by using multiple snapshots.

description: Evolutionary crystal structure prediction proved to be a powerful approach for studying a wide range of materials. Here, we present a specifically designed algorithm for the prediction of the structure of complex crystals consisting of well-defined molecular units. The main feature of this new approach is that each unit is treated as a whole body, which drastically reduces the search space and improves the efficiency, but necessitates the introduction of new variation operators described here. To increase diversity of the population of structures, the initial population and part($\scriptsize{\sim}$20%) of the new generations are generated using space group symmetry combined with random cell parameters and random positions and orientations of molecular units. We illustrate the efficiency and reliability of this approach by number of tests (ice, ammonia, carbon dioxide, methane, benzene, glycine and butane-1,4-diammonium dibromide). This approach easily predicts the crystal structure of methane \emph{A} containing 21 methane molecules (105 atoms) per unit cell. We demonstrate that this new approach has also a high potential for the study of complex inorganic crystals on the examples of a complex hydrogen storage material Mg(BH$_4$)$_2$ and elemental boron.

description: Aims. We compare the predictions of evolutionary models for early-type stars with atmospheric parameters, projected rotational velocities and nitrogen abundances estimated for a sample of Be-type stars. Our targets are located in 4 fields centred on the Large Magellanic Cloud cluster: NGC 2004 and the N 11 region as well as the Small Magellanic Cloud clusters: NGC 330 and NGC 346. Methods. Atmospheric parameters and photospheric abundances have been determined using the non-LTE atmosphere code tlusty. Effective temperature estimates were deduced using three different methodologies depending on the spectral features observed; in general they were found to yield consistent estimates. Gravities were deduced from Balmer line profiles and microturbulences from the Si iii spectrum. Additionally the contributions of continuum emission from circumstellar discs were estimated. Given its importance in constraining stellar evolutionary models, nitrogen abundances (or upper limits) were deduced for all the stars analysed. Results. Our nitrogen abundances are inconsistent with those predicted for targets spending most of their main sequence life rotating near to the critical velocity. This is consistent with the results we obtain from modelling the inferred rotational velocity distribution of our sample and of other investigators. We consider a number of possibilities to explain the nitrogen abundances and rotational velocities of our Be-type sample.

Bayesian optimization for adaptive MCMC

Publisher: name: University of British Columbia

description: A new randomized strategy for adaptive Markov chain Monte Carlo (MCMC) using Bayesian optimization, called Bayesian-optimized MCMC, is proposed. This approach can handle non-differentiable objective functions and trades off exploration and exploitation to reduce the number of function evaluations. Bayesian-optimized MCMC is applied to the complex setting of sampling from constrained, discrete and densely connected probabilistic graphical models where, for each variation of the problem, one needs to adjust the parameters of the proposal mechanism automatically to ensure efficient mixing of the Markov chains. It is found that Bayesian-optimized MCMC is able to match or surpass manual tuning of the proposal mechanism by a domain expert.

Фахівця, що не лише обізнаний у питаннях теорії і практики, але й такого, що спроможний критично осмислювати назрілі проблемні питання, уміти творчо підходити до їх вирішення, інтегруючись таким чином у середовище і змінюючи його.
Потреби постіндустріального суспільства вимагають від сучасного фахівця не лише знань і механістичних умінь, але й здатності критично осмислювати назрілі проблеми, творчо підходити до їх подолання і з усією відповідальністю брати участь у творчій трансформації реальності, а отже, відчувати свою причетність і потрібність. Проте сучасна вітчизняна система освіти є віддзеркаленням учорашнього дня., що в своїй основі опирається на традиційне навчання, переносячи у день завтрашній усі його недоліки.
Подолання назрілих проблем традиційного навчання, що опирається на аналітичне мислення, залишаючи поза увагою творче, можливе, почасти, за умови ширшого впровадження в університетську практику проблемно-орієнтованого навчання за одночасного скорочення наративу у навчальному процесі. Серед методик, які дозволяють це здійснити, є методики модерації та ситуаційного навчання.
Використання модерації та ситуаційних вправ, як і інших інтерактивних навчальних методик є на сьогодні актуальним і доволі перспективним напрямом трансформації навчального процесу – процесу формування конкурентного фахівця, здатного працювати і приймати відповідальні рішення в умовах постіндустріального суспільства. Представлені навчальні методики, попри усю свою позірну простоту, зорієнтовані на цілісність знань та можливість їх застосування, не виходячи за межі аудиторії.

Anisotropic magnetic properties and giant magnetocaloric effect in antiferromagnetic $R$MnO$_3$ crystals ($R$=Dy, Tb, Ho and Yb)

description: We have systematically investigated the magnetic properties and magnetocaloric effect (MCE) in $R$MnO$_3$ ($R$$=$Dy, Tb, Ho and Yb) single crystals. Above a critical value of applied field ($H_c$), $R$MnO$_3$ undergo a first-order antiferromagnetic (AFM) to ferromagnetic (FM) transition below the ordering temperature ($T_{N}^{R}$) of $R^{3+}$ moment and a second-order FM to paramagnetic (PM) transition above $T_{N}^{R}$. Both $H$ and $T$ dependence of $M$ shows that the system is highly anisotropic in the FM as well as PM states and, as a result, the magnetic entropy change ($ΔS_{M}$) is extremely sensitive to the direction of applied field and can be negative (normal MCE) or positive (inverse MCE). For hexagonal HoMnO$_3$ and YbMnO$_3$ systems, a very small inverse MCE is observed only for $H$ parallel to c axis and it decreases with increasing $H$ and crosses over to normal one above $H_c$. On the other hand, for orthorhombic DyMnO$_3$ and TbMnO$_3$, though the inverse MCE disappears above $H_c$ along easy-axis of magnetization, it increases rapidly with $H$ along hard-axis of magnetization for $T$$\ll$$T_{N}^{R}$. Except for YbMnO$_3$, the values of $ΔS_{M}$, relative cooling power and adiabatic temperature change along easy-axis of magnetization are quite large in the field-induced FM state for a moderate field strength. The large values of these parameters, together with negligible hysteresis, suggest that the multiferroic manganites could be potential materials for magnetic refrigeration in the low-temperature region.

description: У підручнику представлено навчальні матеріали для вивчення української літератури другої половини XIX — початку XX століть. У цьому часі відкриється художня самобутність українського письменства, естетична неповторність національної картини буття народу, його розвиток у контексті європейського літературного процесу. Цей період ознаменувався великими перемогами реалізму в літературі, пов’язаними з іменами Івана Нечуя-Левицького, Панаса Мирного, Михайла Старицького, Бориса Грінченка, Івана Карпенка-Карого, Марка Кропивницького, Івана Франка. Українські митці дотримувалися засад демократизму, гуманізму, психологізму та суспільної зумовленості характеру людини. Вони змалювали яскраві картини буття народу, глибоко висвітлили історичні закономірності і фактори, що обумовлюють вчинки і характери героїв. У другій половині XIX століття розквітали драматургія і лірика, розвивалась літературна критика, утверджувався роман як свідчення зрілості української літератури, її європейськості. Виникали нові естетичні явища: натуралізм, модернізм та його стильові течії — символізм, імпресіонізм, неоромантизм, експресіонізм.
Українська література поступово завойовувала європейське визнання. Її пропагандистами на Заході були Марко Вовчок, Михайло Драгоманов, Іван Франко, Ольга Кобилянська, Богдан Лепкий, англійська письменниця Етель Ліліан Войнич, польська поетеса Марія Конопніцька. Читачів вражали моральна краса народу у творах Михайла Коцюбинського, Василя Стефаника, універсалізм Івана Франка і Лесі Українки.
Належне вивчення української літератури в 10 класі дає змогу поглибити літературну освіту, сформувати естетичні смаки, виховати найкращі риси особистості, зокрема патріотизм, гуманізм, активну життєву позицію, навички вирішувати нестандартні ситуації.

description: Mobile applications (apps) have exploded in popularity, with billions of smartphone users using millions of apps available through markets such as the Google Play Store or the Apple App Store. While these apps have rich and useful functionality that is publicly exposed to end users, they also contain hidden behaviors that are not disclosed, such as backdoors and blacklists designed to block unwanted content. In this paper, we show that the input validation behavior—the way the mobile apps process and respond to data entered by users—can serve as a powerful tool for uncovering such hidden functionality. We therefore have developed a tool, InputScope, that automatically detects both the execution context of user input validation and also the content involved in the validation, to automatically expose the secrets of interest. We have tested InputScope with over 150,000 mobile apps, including popular apps from major app stores and pre- installed apps shipped with the phone, and found 12,706 mobile apps with backdoor secrets and 4,028 mobile apps containing blacklist secrets.

description: A general, exact formula is derived for the expectation value of the electromagnetic energy density of an inhomogeneous absorbing and dispersive dielectric medium in thermal equilibrium, assuming that the medium is well approximated as a continuum. From this formula we obtain the formal expression for the Casimir force density. Unlike most previous approaches to Casimir effects in which absorption is either ignored or admitted implicitly through the required analytic properties of the permittivity, we include dissipation explicitly via the coupling of each dipole oscillator of the medium to a reservoir of harmonic oscillators. We obtain the energy density and the Casimir force density as a consequence of the van der Waals interactions of the oscillators and also from Poynting's theorem.

description: Click-jacking protection on the modern Web is commonly enforced via client-side security mechanisms for framing control, like the X-Frame-Options header (XFO) and Content Security Policy (CSP). Though these client-side security mechanisms are certainly useful and successful, delegating protection to web browsers opens room for inconsistencies in the security guarantees offered to users of different browsers. In particular, inconsistencies might arise due to the lack of support for CSP and the different implementations of the underspecified XFO header. In this paper, we formally study the problem of inconsistencies in framing control policies across different browsers and we implement an automated policy analyzer based on our theory, which we use to assess the state of click-jacking protection on the Web. Our analysis shows that 10% of the (distinct) framing control policies in the wild are inconsistent and most often do not provide any level of protection to at least one browser. We thus propose recommendations for web developers and browser vendors to mitigate this issue. Finally, we design and implement a server-side proxy to retrofit security in web applications.

description: In robot assisted surgery, haptic hand controllers are used as an interface between the human oper- ator and a robot manipulator operating on the patient. A well designed haptic hand controller gives users the confidence by allowing the operator to maneuver with ease. There is a desire to translate qualitative preferences to quantifiable design considerations for a hand controller. A teleoperated task related to neurosurgery with three groups of participants and four 6 DOF commercial hand controllers was conducted. Quantitative performance metrics in terms of user effort, motion smoothness, and workspace was evaluated along with qualitative data from questionnaire response. Results provided insights for future designs. A new method for controlling actuation and feedback for bipolar forceps was prototyped and showed improved perception of stiffness and confidence in a user based psychometric experiment. This showed the feasibility and benefits of having the actual tool as part of the hand controller.
Towards improved functionality and performance of intrusion detection systems

description: Based on analysis from collected network traces, a decade of literature in the field of intrusion detection, experiences shared by people in the network security domain, and some new heuristics, this thesis explores several directions in which to extend the functionality and performance of existing Intrusion Detection Systems(IDS). We first present a new method for detecting a whole range of TCP attacks, and an extension of that method for detecting Distributed Denial of Service attacks. We then analyze two directions for enhancing performance: using cloud services to flexibly scale to higher IDS throughput; and leveraging hardware functionality in modern network cards for efficient multi-core processing.

description: The complexity of the common envelope phase and of magnetic stellar wind braking currently limits our understanding of close binary evolution. Because of their intrinsically simple structure, observational population studies of white dwarf plus main sequence (WDMS) binaries hold the potential to test theoretical models and constrain their parameters. The Sloan Digital Sky Survey (SDSS) has provided a large and homogeneously selected sample of WDMS binaries, which we are characterising in terms of orbital and stellar parameters. We have obtained radial velocity information for 385 WDMS binaries from follow-up spectroscopy, and for an additional 861 systems from the SDSS sub-spectra. Radial velocity variations identify 191 of these WDMS binaries as post common envelope binaries (PCEBs). Orbital periods of 58 PCEBs were subsequently measured, predominantly from time-resolved spectroscopy, bringing the total number of SDSS PCEBs with orbital parameters to 79. Observational biases inherent to this PCEB sample were evaluated through extensive Monte Carlo simulations. We find that 21-24% of all SDSS WDMS binaries have undergone common envelope evolution, which is in good agreement with published binary population models and high-resolution HST imaging of WDMS binaries unresolved from the ground. The bias corrected orbital period distribution of PCEBs ranges from 1.9 h to 4.3 d and follows approximately a normal distribution in log(Porb), peaking at ~10.3 h. There is no observational evidence for a significant population of PCEBs with periods in the range of days to weeks. The large and homogeneous sample of SDSS WDMS binaries provides the means to test fundamental predictions of binary population models, and hence to observationally constrain the evolution of all close compact binaries.

description: We investigate several important properties of multi-band superconductors. They are time-reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band superconductors. The BCS (Bardeen-Cooper-Schrieffer) gap equation has a solution with time-reversal symmetry breaking in some cases. We derive the Ginzburg-Landau free energy from the BCS microscopic theory. The frustrating pairing interaction among Fermi surfaces leads to a state with broken time-reversal symmetry, that is, a chiral solution. The Ginzburg-Landau equation for three-component superconductors leads to a double sine-Gordon model. A kink solution exists to this equation as in the conventional sine-Gordon model. In the chiral region of the double sine-Gordon model, an inequality of Bogomol'nyi type holds, and fractional-$π$ kink solutions exist with the topological charge Q. This yields multi-vortex bound states in three-band superconductors.

description: Using the Herschel PACS and SPIRE FIR/submm data, we investigate variations in the dust spectral index $β$ in the nearby spiral galaxy M33 at a linear resolution of 160 pc. We use an iteration method in two different approaches, single and two-component modified black body models. In both approaches, $β$ is higher in the central disk than in the outer disk similar to the dust temperature. There is a positive correlation between $β$ and Halpha as well as with the molecular gas traced by CO(2-1). A Monte-Carlo simulation shows that the physical parameters are better constrained when using the two-component model.

Poétique des frontières dans le roman francophone africain et caribéen

description: This study explores, on the one hand, the interactions between narratives and other art and media forms within the narrative and, on the other, the correlation between fiction and non-fiction. Within the context of new trends in francophone literature since the 90s where the novel has become a genre without limit, the work interrogates the reconfiguration of discursive space of the francophone novel made of interactions and transgressions. It focalises on the mixture of genres, the interaction between the fictional text and the paratextual elements (title, preface, postface, foot and endnotes etc.), the narrative text and media forms of expression, and the violence which characterises the elements of narration. The study is based on six novels of six different writers of sub-Saharan Africa and Haiti. This choice is informed by the desire to compare the aesthetics of these writers of different periods, as well as that of the two territories identified notably by cultural and sociological resemblance. This study will be conducted in the light of a comparative research methodology, using elements of the theory of dialogism of Mikhail Bakhtin, coupled with the concepts of intertextuality, intermediality, and the mosaic which deal basically with the interaction of various discourses, voices, and genres, bringing out the conflicting and complementing relationship within a shared space. The analysis reveals that current media and technological advancement and improved culture of mobility which have banished frontiers, account for the loss identities and the creation multifaceted space in literary works. Besides, the fashionable transgression of discursive practices and subversion of established orders have decompartmentalised the literary expression, widening its horizons and giving it a global and a transfrontiers outlook. To this end, the notion of frontiers in the contemporary francophone novel surpasses the status of a theme and imposes itself rather as a framework for the reading of the novel.

TeV cosmic ray electrons from millisecond pulsars

name: Kawanaka, Norita
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Recent γ-ray observations suggest that the γ-ray millisecond pulsar (MSP) population is separated into two sub-classes with respect to the pair multiplicity. Here, we calculate the cosmic ray electron/positron spectra from MSPs. Based on the assumption of the equipartition in the pulsar wind region the typical energy of electrons/positrons ejected by a MSP with the pair multiplicity of order unity is \sim 50 TeV. In this case, we find that a large peak at 10 - 50 TeV energy range would be observed in the cosmic ray electron/positron spectrum. Even if the fraction of pair starved MSPs is 10%, the large peak would be detectable in the future observations. We also calculate the contribution from MSPs with high pair multiplicity to the electron/positron spectrum. We suggest that if the multiplicity of dominant MSP population is \sim 10^3, electrons/positrons from them may contribute to the observed excess from the background electron/positron flux and positron fraction.

Acres of diamonds: a heuristic self-search inquiry into intuition
Creators: name: Meents, JoAnne
Publisher: name: University of Calgary
Year: 2006

description: Bibliography: p. 249-271
description: My dissertation is a qualitative, exploratory research study of how I, as the researcher, experience intuition. My study is unusual in that it represents one of the first formal, recognized applications of heuristic self-search inquiry (HSSI), a rigorous, relatively new and relatively unknown research approach developed by Sandy Sela-Smith (2002a; 2002b). My research is unique in that it offers an alternative to the HSSI application Sela-Smith advocates. My research is also unique as it represents the first HSSI into intuition. To me HSSI is about staying in one place and digging deep into internal landscapes in search of "acres of diamonds." This dissertation, then, is about unearthing my internal understanding of myself in relationship to intuition; it is not about understanding intuition as an external phenomenon, as most research approaches would require. My focus is on process. The dissertation tells the story of how I uncovered my research question (how do I experience intuition?), the internal process I went through to find my answers, and what those answers mean to me. It reflects my intuitive nature. The dissertation describes in detail my application of HSSI, my resistance to the internal search required of HSSI, and my surrender to HSSl's phases (initial engagement, immersion, incubation, illumination, explication, creative synthesis and my own addition, validation) and concepts and processes (identification with the focus of the inquiry, tacit knowing, intuition, indwelling, self-dialogue, focusing, feelings, and internal frame of reference) as I came to understand and appreciate what intuition means to me. I discuss personal discoveries about transformation and heuristic containers uncovered through the course of my inquiry that helped me and may help others conducting similar first-person research. I consider validity in detail- HSSl's validity as a research methodology, the validity of my research as HSSI, the validity of my application of HSSI, and the truth of my research findings-in seeking to answer the question, "Is THIS research?" Lastly, I present my research contributions for the study of HSSI, intuition, and transformation and implications arising from my work for the areas of HSSI, intuition, transformation, and my own internal explorations.

description: У підручнику представлено навчальні матеріали для вивчення української літератури другої половини XIX — початку XX століть. У цьому часі відкриється художня самобутність українського письменства, естетична неповторність національної картини буття народу, його розвиток у контексті європейського літературного процесу. Цей період ознаменувався великими перемогами реалізму в літературі, пов’язаними з іменами Івана Нечуя-Левицького, Панаса Мирного, Михайла Старицького, Бориса Грінченка, Івана Карпенка-Карого, Марка Кропивницького, Івана Франка. Українські митці дотримувалися засад демократизму, гуманізму, психологізму та суспільної зумовленості характеру людини. Вони змалювали яскраві картини буття народу, глибоко висвітлили історичні закономірності і фактори, що обумовлюють вчинки і характери героїв. У другій половині XIX століття розквітали драматургія і лірика, розвивалась літературна критика, утверджувався роман як свідчення зрілості української літератури, її європейськості. Виникали нові естетичні явища: натуралізм, модернізм та його стильові течії — символізм, імпресіонізм, неоромантизм, експресіонізм.
Українська література поступово завойовувала європейське визнання. Її пропагандистами на Заході були Марко Вовчок, Михайло Драгоманов, Іван Франко, Ольга Кобилянська, Богдан Лепкий, англійська письменниця Етель Ліліан Войнич, польська поетеса Марія Конопніцька. Читачів вражали моральна краса народу у творах Михайла Коцюбинського, Василя Стефаника, універсалізм Івана Франка і Лесі Українки.
Належне вивчення української літератури в 10 класі дасть вам змогу поглибити літературну освіту, сформувати естетичні смаки, виховати найкращі риси особистості, зокрема патріотизм, гуманізм, активну життєву позицію, навички вирішувати нестандартні ситуації.

description: We construct two parametrizations of the non compact exceptional Lie group G=E7(-25), based on a fibration which has the maximal compact subgroup K=(E6 x U(1))/Z_3 as a fiber. It is well known that G plays an important role in the N=2 d=4 magic exceptional supergravity, where it describes the U-duality of the theory and where the symmetric space M=G/K gives the vector multiplets' scalar manifold. First, by making use of the exponential map, we compute a realization of G/K, that is based on the E6 invariant d-tensor, and hence exhibits the maximal possible manifest [(E6 x U(1))/Z_3]-covariance. This provides a basis for the corresponding supergravity theory, which is the analogue of the Calabi-Vesentini coordinates. Then we study the Iwasawa decomposition. Its main feature is that it is SO(8)-covariant and therefore it highlights the role of triality. Along the way we analyze the relevant chain of maximal embeddings which leads to SO(8). It is worth noticing that being based on the properties of a "mixed" Freudenthal-Tits magic square, the whole procedure can be generalized to a broader class of groups of type E7.

description: When considering a material for use as a catalyst or adsorbent, its pore structure is important, and can be determined by nitrogen gas adsorption. This thesis focuses on activated carbon materials prepared from petroleum coke, which are challenging to characterize due to the difficulties in modelling their disordered pore structures. The published models used to calculate the pore structure from experimental data have been reviewed and compared. From this review a procedure has been developed to select the most appropriate model for the material being studied, which is generally based on 2-Dimensional Non-Local Density Functional Theory, and applied to four carbon materials with varying pore structures. The results from this procedure show that pore structure properties can be calculated from a single model, and have been complemented with carbon dioxide adsorption, hysteresis scanning isotherms, and helium ion microscopy images but further work is recommended with the latter two methods.
