On the vortex evolution in non-isothermal protoplanetary discs

description: It is believed that large-scale horseshoe-like brightness asymmetries found in dozens of transitional protoplanetary discs are caused by anticyclonic vortices. These vortices can play a key role in planet formation, as mm-sized dust -- the building blocks of planets -- can be accumulated inside them. Anticyclonic vortices are formed by the Rossby wave instability, which can be excited at the gap edges opened by a giant planet or at sharp viscosity transitions of accretionally inactive regions. It is known that vortices are prone to stretching and subsequent dissolution due to disc self-gravity for canonical disc masses in the isothermal approximation. To improve the hydrodynamic model of protoplanetary discs, we include the disc thermodynamics in our model. In this paper, we present our results on the evolution of the vortices formed at the outer edge of an accretionally inactive region (dead zone) assuming an ideal equation of state and taking $PdV$ work, disc cooling in the $β$-approximation, and disc self-gravity into account. Thermodynamics affects the offset and the mode number (referring to the number of small vortices at the early phase) of the RWI excitation, as well as the strength, shape, and lifetime of the large-scale vortex formed through merging of the initial small vortices. We found that the inclusion of gas thermodynamics results in stronger, however decreased lifetime vortices. Our results suggest that a hypothetical vortex-aided planet formation scenario favours effectively cooling discs.

title: Synthesis of activity-based probes for the metalloprotease CSN5

description: The Cullin-RING E3 ligase (CRL) family consists of over 200 enzymes that are responsible for the ubiquitylation and regulation of a huge variety of proteins involved in the immune response, cell cycle control and cell proliferation. CRLs are activated by covalent attachment to the C-terminus of the ubiquitin-like modifier NEDD8 by forming an isopeptide bond in a process called NEDDylation. Inhibition of CRLs is mediated by the COP9 signalosome complex (CSN) which cleaves the isopeptide bond binding to NEDD8 and removes it. CRL homeostasis is disrupted by CSN overactivity and is associated with the pathogenesis of ~50% of all cancers in humans. The means by which the activity of the catalytic subunit of CSN (CSN5) is regulated is not fully understood and thus new tools are required to study its activity. CSN5 contains a JAMM domain with a Zn2+ atom facilitating its catalytic activity. The synthesis of several activity-based probes for CSN5 was attempted, each containing a zinc-binding group (ZBG) for attachment onto the catalytic site, a NEDD8 peptide to enable selectivity to CSN5 and a biotin tag for subsequent biochemical assays. Three zinc-binding groups were considered including hydroxamic acid, imidazole and a precursor of a potent small molecule CSN5 inhibitor, CSN5i-3. The multi-step synthesis of the CSN5i-3 precursor was attempted but not completed due to time constraints. In an endeavour to mimic the entire substrate of CSN5, the synthesis of NEDD8 was attempted but not successful. In a separate approach, a peptide of the NEDD8 C-terminal tail was synthesised and successfully biotinylated, however conjugation to the zinc-binding groups hydroxamic acid and imidazole were unsuccessful due to the low solubility of the peptide.
The Future of Middle-Skill Jobs

description: We analyze the likely trends in supply and demand for workers with different levels of education and training over the next decade and beyond. We present data on the current distributions of jobs and wages, and how these distributions have evolved in the recent past; we also review projections from the Bureau of Labor Statistics on future demand by occupation. We compare these demand-side projections with forecasts of the supply of workers with varying levels of education and training. Overall, we conclude that the demand for middle-skill workers will remain quite robust relative to its supply, especially in key sectors of the economy. A range of policies could help low-income workers obtain more education and training for these middle-skill jobs, thereby raising their earnings and their family’s living standards.

description: Over the last decade, more intermittent renewable power has been introduced to the power grid, causing instabilities in the power grid and fluctuations in the price of electricity. Nuclear-renewable hybrid energy systems (NHES) have been proposed as a potential solution. These systems can take advantage of flexible loads and energy storage to more flexibly meet the demands of highly-dynamic power grids. Economical operation of these systems requires careful optimization. In this project, a simple NHES model is developed to capture the dynamic operational behavior of these systems. The operation of this model is then optimized to minimize economic costs. A series of optimizers and algorithms, including but not limited to SNOPT, SLSQP, Nelder-Mead, and Fmincon, are then benchmarked for the optimization process. The resulting strengths and weaknesses of each solver for this problem domain are then compared and reported.

La parole, l'identité, l'incarnation dans "Une légère blessure"

Publisher: name: Università degli Studi di Trento. Dipartimento di Lettere e Filosofia.
Year: 2021

description: Le monologue d’Une légère blessure unit l’examen de soi à la confidence. Ce double niveau de parole ne se réalise pas sans tension générique, et l’on pourrait dire, en forçant la langue, que la Femme se parle à sa domestique. L’examen de soi est un discours qui se retourne sur lui-même et qui suit le mouvement de la conscience, alors que la confidence est adressée à un allocutaire (la domestique) dont on recherche la compréhension et le soutien en investissant une position discursive particulière. En effet, dans la structure de la confidence, la Femme s’attribue un rôle de confieuse. Au-delà des motifs fictionnels, le monologue d’Une légère blessure déploie une forme de mise en abyme, entre l’essence du théâtre et la situation du personnage. Cette pièce est bâtie sur une poétique spéculaire : à partir d’une parole travaillée par le rapport du sujet à son identité, Laurent Mauvignier met en scène la théâtralité ; mais en reflet, à partir de la théâtralité, Laurent Mauvignier met en scène le rapport du sujet à son identité.

By implementing two new estimators alongside preexisting estimators, the bmte command provides a picture of the average causal effects of the treatment across a variety of assumptions.

Highly Efficient Porous FexCe1–xO2−δ with Three-Dimensional Hierarchical Nanoflower Morphology for H2S-Selective Oxidation
Creators: name: Zheng, Xiaohai
Publisher: name: figshare
Year: 2020
Subjects: Environmental Chemistry

description: CeO2-based catalysts are potentially suitable for H2S selective oxidation, but their practical application is limited due to the problem of sulfate formation. Herein, we report a facile citric acid-assisted hydrothermal process for the fabrication of porous Fe-doped CeO2 with flower-like morphology that can drastically promote the catalytic activities of CeO2 with high durability. Among the synthesized catalysts, the one with well-defined (110) and (100) planes is highly active for H2S selective oxidation with H2S conversion and sulfur selectivity of almost 100% at 220 °C, superior to most of the reported Ce-based catalysts. Meanwhile, outstanding catalytic stability is achieved because the presence of Fe ions alleviates ceria deactivation due to sulfation. The results of systematic investigation prove that the doping of Fe not only raises the density of oxygen vacancies, but also promotes the redox ability and oxygen activity of the catalyst. We conducted in situ DRIFTS experiments and density functional theory (DFT) calculations to disclose the reaction mechanism of H2S oxidation. The derived insights are important for the design of efficient ceria-related catalysts for practical applications.

For nonstationary heterogeneous panels that are long (large T) and wide (large N), xtpedroni tests for cointegration among one or more regressors by using seven test statistics under the null of no cointegration, and it also estimates the cointegrating equation for each individual as well as the group mean of the panel.

description: George Taylor was a great uncle on my Mother's side. He was born on June 6 1882 at Beauvale, Newthorpe, Nottinghamshire, England. He was the son of Zachariah and Millicent Taylor. Zachariah Taylor married Millicent Clarke on December 8 1879. His siblings were: Ernest Taylor born March 13 1881, Arthur Taylor born October 16 1885, Alice Taylor born February 28 1887, Percy Taylor born November 29 1891 and Benjamin Robert Taylor born July 24 1899. Alice Taylor married Henry Marriott in 1911. Ernest, Benjamin Robert and another son also served in the First World War; Benjamin died of injuries.

George served in France. According to his discharge papers George Taylor enlisted on 14/09/1914 at Nottingham. In civilian life he had been a coal miner. His regimental number was 12766. He was discharged on 14/09/1916 at Lichfield in consequence of being no longer fit for War Service. He died from injuries on 26 March 1918. He is buried at Greasley (St Mary) Churchyard and Cemetery, Nottinghamshire. The inscription on his gravestone reads "SERVED AND SACRIFICED".

We have a letter to Benjamin (Ben) written by George when he was in hospital. In the letter he refers to attending an event at the Albert Hall; 'just before the meeting commenced all us boys 3,000 in all sang the old trench songs and it sounded grand'. He refers in the letter to Ben's hansom and encloses a one franc note.

description: We demonstrate advantages of non-standard grading for computing cohomology of restricted Hamiltonian and Poisson algebras. These algebras contain the inner grading element in the properly defined symmetric grading compatible with the symplectic structure. Using modulo p analog of the theorem on the structure of cohomology of Lie algebra with inner grading element, we show that all nontrivial cohomology classes are located in the grades which are the multiples of the characteristic p. Besides, this grading implies another symmetries in the structure of cohomology. These symmetries are based on the Poincare duality and symmetry with respect to transpositions of conjugate variables of the symplectic space. Some results obtained by computer program utilizing these peculiarities in the cohomology structure are presented.

description: Si les romans de Laurent Mauvignier sont déjà connus en Italie, son théâtre en revanche, pourtant essentiel à la compréhension de son oeuvre, semble bien jusqu’à maintenant être ignoré. Cet ouvrage est donc destiné à faire connaître l’oeuvre théâtrale de Laurent Mauvignier. Il le fait de deux manières : d’une part, en mettant à la disposition des lecteurs, dans une édition bilingue, les traductions d’Alberto Bramati de "Tout mon amour" et de "Une légère blessure" ; et d’autre part, en accompagnant ces traductions par six études universitaires qui approfondissent la réflexion sur une oeuvre qui est tout à la fois polygraphique, transgénérique et hybride, car elle met en cause l’identité et la nature des genres dont elle s’empare. On ne saurait saisir l’oeuvre de Laurent Mauvignier en négligeant la dynamique d’une écriture qui, du roman au théâtre, retravaille les genres littéraires. D’ailleurs, le lien entre les genres romanesque et dramatique est d’autant plus important que, comme le rappellent plusieurs articles présents dans cet ouvrage, les romans de Laurent Mauvignier sont marqués par une évidente forme de théâtralité, en raison de leurs structures, de leurs dispositifs de langage et de leurs effets d’oralité. Convaincus par cette théâtralité des récits, de nombreux artistes de théâtre ont en effet songé à des adaptations scéniques et pour certains les ont réalisées. Ainsi en publiant des pièces, Laurent Mauvignier semble donc, pour partie, accomplir une qualité intrinsèque de son écriture, déjà présente dans ses récits.

description: An eigenvalue based framework is developed for the stability analysis and stabilization of coupled systems with time-delays, which are naturally described by delay differential algebraic equations. The spectral properties of these equations are analyzed and their stability properties are studied, taking into account the effect of small delay perturbations. Subsequently, numerical methods for stability assessment and for designing stabilizing controllers with a prescribed structure or order, based on a direct optimization approach, are briefly addressed. The effectiveness of the approach is illustrated with a software demo. The paper concludes by pointing out the similarities with the computation and optimization of H-infinity norms.

description: We examine metastable and transient effects both above and below the first-order decoupling line in a 3D simulation of magnetically interacting pancake vortices. We observe pronounced transient and history effects as well as supercooling and superheating between the 3D coupled, ordered and 2D decoupled, disordered phases. In the disordered supercooled state as a function of DC driving, reordering occurs through the formation of growing moving channels of the ordered phase. No channels form in the superheated region; instead the ordered state is homogeneously destroyed. When a sequence of current pulses is applied we observe memory effects. We find a ramp rate dependence of the V(I) curves on both sides of the decoupling transition. The critical current that we obtain depends on how the system is prepared.

title: Trafficked women in the media: discursive constructions of trafficked women in three media genres
Creators: name: Stolic, Tijana
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: In this thesis I explore how women trafficked for sexual exploitation emerge as subjects of public pity in media discourse. I do this by analysing their depictions in three media genres: film, celebrity advocacy, and newspaper journalism. The broad goal of the study is to understand how proposals for emotional and moral obligation towards trafficked women are constructed in the mediated communication of human trafficking. More specifically, I explore the dichotomy between ideal and undeserving victimhood through an intersectional lens by analysing how the embodiment, agency, and vulnerability of trafficked women are constructed in the media. The analytics of mediation is employed as a methodological approach, combining multimodal and critical discourse analysis as tools for analysing data. My thesis reveals that representations of trafficked women are characterised by discursive ambivalence and that dominant trafficking discourses, which coalesce around depictions of naïve, innocent, young women exploited by evil traffickers carry the most visibility, which is reflected in laws, policies, and humanitarian and human rights appeals. But more importantly, rather than an absence of marginalised identities and narratives, this study shows that victim hierarchies legitimate only those voices which are already dominant in social and institutional discourse. In other words, victim hierarchies are problematic not only because they highlight some groups as particularly worthy of public pity, but because they create and perpetuate dominant discourses at the expense of contextualising and politicising marginalised subjectivities and experiences. Victim hierarchies, therefore, result in a discursive ambivalence within semiotic texts that do carry political potential but, as it is, fall short of giving full political agency to those trafficked women whose experiences and identities do not conform to notions of ideal victimhood.

description: Lewis Mathieson was my great uncle. He was the youngest of four brothers, the eldest brother being my grandfather, James Mathieson. Lewis followed his three brothers into the Gordon Highlanders, enlisting on 17th August 1903. He served in India and was discharged into the reserve on 6th January 1912. Please see the biography of Lewis that I have written for the story of Lewis in the First World War, his desertion from the army, his subsequent enrolment into the Royal Navy Reserve and his participation in the Battle of Jutland. The story is briefly summarised below.
On the outbreak of the First World War Lewis was mobilised into the 1st Battalion of the Gordon Highlanders and by Sunday 23rd August the Gordons were in position south-west of Mons. In 1915 Lewis was invalided home with frostbite in both feet. He was successfully treated. He reported fit for duty but then decided he would soldier no more and deserted. However, on 30th July 1915 Lewis joined the Royal Navy Reserve using the alias, Alexander Wood, and taking the rating of Stoker. After training he joined HMS Malaya on 28th January 1916. He took part in the Battle of Jutland and received good assessments, Superior for ability and Very Good for conduct.

Lewis Mathieson was awarded the 1914 Star with clasp, the British War Medal and the Victory Medal in spite of being a deserter, the latter two awards being authorised by the Admiralty in respect of service of Wood A.

Using the known values for the chi_c0 decays branching fractions, we combine these results to obtain BR(B+- --> chi_c0 K+-) = (2.7+-0.7)* 10^-4.

description: Accurate and efficient aeroelastic models are critically important for enabling the optimization and control of highly flexible aerospace structures, which are expected to become pervasive in future transportation and energy systems. Advanced materials and morphing wing technologies are resulting in next-generation aeroelastic systems that are characterized by highly-coupled and nonlinear interactions between the aerodynamic and structural dynamics. In this work, we leverage emerging data-driven modeling techniques to develop highly accurate and tractable reduced-order aeroelastic models that are valid over a wide range of operating conditions and are suitable for control. In particular, we develop two extensions to the recent dynamic mode decomposition with control (DMDc) algorithm to make it suitable for flexible aeroelastic systems: 1) we introduce a formulation to handle algebraic equations, and 2) we develop an interpolation scheme to smoothly connect several linear DMDc models developed in different operating regimes. Thus, the innovation lies in accurately modeling the nonlinearities of the coupled aerostructural dynamics over multiple operating regimes, not restricting the validity of the model to a narrow region around a linearization point. We demonstrate this approach on a high-fidelity, three-dimensional numerical model of an airborne wind energy (AWE) system, although the methods are generally applicable to any highly coupled aeroelastic system or dynamical system operating over multiple operating regimes. Our proposed modeling framework results in real-time prediction of nonlinear unsteady aeroelastic responses of flexible aerospace structures, and we demonstrate the enhanced model performance for model predictive control. Thus, the proposed architecture may help enable the widespread adoption of next-generation morphing wing technologies.

description: We apply a recently introduced reduction procedure based on the embedding of non-crystallographic Coxeter groups into crystallographic ones to Calogero-Moser systems. For rational potentials the familiar generalized Calogero Hamiltonian is recovered. For the Hamiltonians of trigonometric, hyperbolic and elliptic type, we obtain novel integrable dynamical systems with a second potential term which is rescaled by the golden ratio. We explicitly show for the simplest of these non-crystallographic models how the corresponding classical equations of motion can be derived from a Lie algebraic Lax pair based on the larger, crystallographic Coxeter group.

description: We report a theoretical study of sulphur chemistry, as applied to hot cores, where S-bearing molecular ratios have been previously proposed and used as chemical clocks. As in previous models, we follow the S-bearing molecular composition after the injection of grain mantle components into the gas phase. For this study, we developed a time-dependent chemical model with up-to-date reaction rate coefficients. We ran several cases, using different realistic chemical compositions for the grain mantles and for the gas prior to mantle evaporation. The modeling shows that S-bearing molecular ratios depend very critically on the gas temperature and density, the abundance of atomic oxygen, and, most importantly, on the form of sulphur injected in the gas phase, which is very poorly known. Consequently, ratios of S-bearing molecules cannot be easily used as chemical clocks. However, detailed observations and careful modeling of both physical and chemical structure can give hints on the source age and constrain the mantle composition (i.e. the form of sulphur in cold molecular clouds) and, thus, help to solve the mystery of the sulphur depletion. We analyse in detail the cases of Orion and IRAS16293-2422. The comparison of the available observations with our model suggests that the majority of sulphur released from the mantles is mainly in, or soon converted into, atomic form.

HHH also implements a novel text representation and similarity deep learning model, Hierarchical BiLSTM Attention Model (HBAM), to find the most similar question from a large QA dataset. We compare HBAM with other state-of-the-art language models such as bidirectional encoder representation from transformers (BERT) and Manhattan LSTM Model (MaLSTM). We train and test the models with a subset of the Quora duplicate questions dataset in the medical area. The experimental results show that our model is able to achieve a superior performance than these existing methods.

description: Trees can become an attractive integral component of farming systems by demonstrating that they are as profitable than traditional agricultural crops. Agroforestry systems help address the short-term profitability needs of the farmer while achieving long-term goals of maintaining yields and the environment. This study compares the profitabilities of traditional crops and an agroforestry system. A linear programming model finds an optimal farming alternatives through long-term financial analysis. The results are presented in the context of scenarios which include different discount rates and land quality classifications.
title: An Investigation into the relevance of JH Newman's Essay in Aid of a Grammar of Assent for the practice and development of Key Stage Three Religious Education in a Catholic School
Creators: name: Gray, Alison
Publisher: name: The Open University
Year: 2007

description: This study investigates the principles and arguments of JH Newman's Essay in Aid of a Grammar of Assent. Newman argued that the mind receives impressions of revealed truth, which form a real and permanent inward knowledge that may be recognised implicitly or explicitly by those who possess it. This recognition is considered by Newman to be an insight into the act of assent to religious belief before it can be understood and explained. According to Newman's epistemology as articulated in the Grammar (in the principles of perception, apprehension, assent and inference, first principles, conscience, certitude and the illative sense) the human person can believe without understanding and proof.

This is the hypothesis that is the driving force of this study that uses bracketing to isolate Key Stage Three (11-14 years) pupil insights in accord with qualitative research methods. The pupils of a Catholic Comprehensive in the Greater London area in this study discovered and experimented with age-old and contemporary conventions within the domain of the Philosophy of Religion in response to problem-solving tasks set on the doctrine of the Trinity. This teaching and learning took place long before a secular educational paradigm driven by stage theory would consider feasible. The perception of doctrine as provocative educational materials that the Catholic Church enforces through the processes of indoctrination is not verified in this study. The cognitive challenges of doctrine were found to be no more or less than the cognitive capacities of students. Teaching methodology needs to take a strong account of the teacher as expert as well as the teacher as facilitator of learning. Newman's epistemology reveals the human person as a believing person demonstrating the inherent capacity to believe is critical to an understanding of how pupils learn in religious and non-religious matters.
Effect of Semicore Orbitals on the Electronic Band Gaps of Si, Ge, and GaAs within the GW Approximation

description: We study the effect of semicore states on the self-energy corrections and electronic energy gaps of silicon, germanium and GaAs. Self-energy effects are computed within the GW approach, and electronic states are expanded in a plane-wave basis. For these materials, we generate {\it ab initio} pseudopotentials treating as valence states the outermost two shells of atomic orbitals, rather than only the outermost valence shell as in traditional pseudopotential calculations. The resulting direct and indirect energy gaps are compared with experimental measurements and with previous calculations based on pseudopotential and ``all-electron'' approaches. Our results show that, contrary to recent claims, self-energy effects due to semicore states on the band gaps can be well accounted for in the standard valence-only pseudopotential formalism.

description: While charged lepton flavor violation (cLFV) with taus is often expected to be largest in many extensions of the Standard Model (SM), it is currently much less constrained than cLFV with electrons and muons. We study the sensitivity of the LHeC to $e$-$τ$ (and $e$-$μ$) conversion processes $p e^- \to τ^- + j$ (and $p e^- \to μ^- + j$) mediated by a $Z'$ with flavor-violating couplings to charged leptons in the $t$-channel. Compared to current tests at the LHC, where cLFV decays of the $Z'$ (produced in the s-channel) are searched for, the LHeC has sensitivity to much higher $Z'$ masses, up to O(10) TeV. For cLFV with taus, we find that the LHeC sensitivity from the process $p e^- \to τ^- + j$ can exceed the current limits from collider and non-collider experiments in the whole considered $Z'$ mass range (above $500$ GeV) by more than two orders of magnitude. In particular for extensions of the SM with a heavy $Z'$, where direct production at colliders is kinematically suppressed, $e-τ$ conversion at LHeC provides an exciting new discovery channel for this type of new physics.

Modeling cloth behavior using penalty optimization

Subjects: Applied Computer Science

description: The purpose of this research was to investigate methods in optimization that could be used to accomplish digital fitting. As an initial step towards this goal, this study sought to develop an algorithm that would replicate the behaviour of a cloth interacting with a sphere. The basic approach was to model the cloth as a mesh of nodes connected by linear springs. A function that calculated the total potential, spring, and bending energy of all nodes was used as an objective function for optimization. Using these calculations, it was found that a reasonable approximation of cloth behaviour could be generated. However, the optimization of this simplified model was too computationally expensive to be implemented as a viable commercial solution to the problem. Recommendations for improvements are given in the final section of this report.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Benjamin Robert Taylor was a great uncle on my mother's side. He was born on July 24 1899 at Beauvale, Newthorpe, Nottinghamshire, England. He was the son of Zachariah and Millicent Taylor. Zachariah Taylor married Millicent Clarke on December 8 1879. His siblings were: Ernest Taylor born March 13 1881, George Taylor born June 6 1882, Arthur Taylor born October 16 1885, Alice Taylor born February 28 1887 and Percy Taylor born November 29 1891.He died on 14 May 1918. He is buried at Bagneux British Cemetery, Gezaincourt, Somme, France.

title: Systematic studies in Neotropical Myrtaceae with an emphasis on Myrcia s.l.: The evolution and biogeography of a large South American clade
Creators: name: Lucas, E.J.
Publisher: name: The Open University
Year: 2007

description: Low morphological variation at all taxonomic levels give Neotropical Myrtaceae a reputation as a 'difficult' family to identify even to genus, resulting in a lack of taxonomic data on every front. The subtribal classification of the predominantly Neotropical and exclusively fleshy-fruited tribe Myrteae (49 genera and c. 2500 species) is unstable, as are generic boundaries within it. Neotropical Myrtaceae are particularly species rich in some of South America's most threatened habitats. The second largest Neotropical genus, Myrcia s.l., comprises >700 taxonomically 'difficult' species with species diversity reaching its peak in the Brazilian Atlantic rainforest and cerrado, habitats in urgent need of inventories of their plant species before conservation initiatives can be undertaken.

Phylogenetic hypotheses are provided for evolutionary relationships within Myrteae and Myrcia s.l. based on nuclear ITS and ETS ribosomal DNA and plastid psbA-trnH and matK DNA sequences, using parsimony and Bayesian inference. Four morphological characters of Myrteae are optimized on the resulting trees and nineteen are used in a cladistic analysis of Myrcia s.l. Myrteae appear monophyletic, comprising seven clades plus two isolated taxa. Of the four previously accepted genera of subtribe Myrciinae sensu DC., two are polyphyletic and all emerge in a single clade treated here as Myrcia s.l. Morphological characters exhibit homoplasy at both ranks, although in combination are useful for clade diagnosis.

Biogeographical analysis is inconclusive regarding tribal ancestral areas, but South American colonization before northern radiation via the Andes appears likely. The largest genera, Eugenia and Myrcia s.l., have western and southeastern South American origins, respectively. Nonmetric multidimensional scaling and ordination techniques are employed to divide the distribution of Myrcia s.l. into discrete areas of endemism and historical biogeographical scenarios are discussed. Finally, modern, natural, subtribal and infrageneric classifications are proposed and concluding inferences are drawn regarding drivers of large genera using Myrtaceae and Myrcia s.l. as case studies.
