description: We present new measurements of the Rossiter-McLaughlin (RM) effect for three WASP planetary systems, WASP-16, WASP-25 and WASP-31, from a combined analysis of their complete sets of photometric and spectroscopic data. We find a low amplitude RM effect for WASP-16 (Teff = 5700 \pm 150K), suggesting that the star is a slow rotator and thus of an advanced age, and obtain a projected alignment angle of lambda = -4.2 degrees +11.0 -13.9. For WASP-25 (Teff = 5750\pm100K) we detect a projected spin-orbit angle of lambda = 14.6 degrees \pm6.7. WASP-31 (Teff = 6300\pm100K) is found to be well-aligned, with a projected spin-orbit angle of lambda = 2.8degrees \pm3.1. A circular orbit is consistent with the data for all three systems, in agreement with their respective discovery papers. We consider the results for these systems in the context of the ensemble of RM measurements made to date. We find that whilst WASP-16 fits the hypothesis of Winn et al. (2010) that 'cool' stars (Teff < 6250K) are preferentially aligned, WASP-31 has little impact on the proposed trend. We bring the total distribution of the true spin-orbit alignment angle, psi, up to date, noting that recent results have improved the agreement with the theory of Fabrycky & Tremaine (2007) at mid-range angles. We also suggest a new test for judging misalignment using the Bayesian Information Criterion, according to which WASP-25 b's orbit should be considered to be aligned.

description: Trojan asteroids are minor planets that share the orbit of a planet about the Sun and librate around the L4 or L5 Lagrangian points of stability. Although only three Mars Trojans have been discovered, models suggest that at least ten times this number should exist with diameters >= 1 km. We derive a model that constrains optimal sky search areas and present a strategy for the most efficient use of telescope survey time that maximizes the probability of detecting Mars Trojans. We show that the Gaia space mission could detect any Mars Trojans larger than 1 km in diameter, provided the relative motion perpendicular to Gaia's CCD array is less than 0.40 arcsec per second.

description: Understanding the mechanisms by which competing species coexist is fundamental to explaining nature’s biodiversity. One hypothesis is that intraspecific diversity promotes species coexistence. A number of ecological and evolutionary mechanisms have been identified through which intraspecific diversity can generate stabilizing mechanisms, those that increase the negative frequency-dependence of population growth. However, intraspecific diversity, can also increase a species’ competitive ability through a number of ecological and evolutionary mechanisms, altering equalizing mechanisms and potentially destabilizing coexistence. Modern coexistence theory provides a framework for understanding how these two suites of mechanisms interact: decreases in equalizing mechanisms must be compensated for by increases in stabilizing mechanisms to maintain the stability of coexistence. In this thesis, I explore how intraspecific diversity affects stabilizing and equalizing mechanisms using a classic subject of competition and coevolution studies, bruchid beetles (Callosobruchus spp.). I explored the ecological consequences of intraspecific diversity for coexistence by assaying the coexistence (mutual invasibility) of populations of two competing species (Callosobruchus maculatus and C. chinensis) when each comprised one, three, or five genetically- and phenotypically-distinct lineages. Populations composed of five lineages were then experimentally evolved in sympatry or allopatry to explore the evolutionary consequences of intraspecific diversity. Through periodic assays of life-history traits I tested for ecological character displacement. After assaying each population’s phenotype, I assayed population-pairs for mutual-invasibility to explore how adaptive evolution alters species coexistence. In both the short- and long-term, intraspecific diversity often inhibited coexistence, rather than promoting it. Intraspecific diversity promoted both ecological and evolutionary stabilizing mechanisms, but often had a negative effect on equalizing mechanisms. Intraspecific diversity increased species’ competitive abilities through a combination of ecological (e.g., niche complementarity) and evolutionary (e.g., selection effects) mechanisms. Similar increases in competitive ability by coexisting species maintained fitness equality and strengthened coexistence, due to a strengthening of stabilizing mechanisms, as predicted. However, species often experienced different gains in competitive ability, destabilizing coexistence. I review the mechanisms by which intraspecific diversity alters equalizing mechanisms and identify a need to better understand how these mechanisms interact.
R-parity Conservation via the Stueckelberg Mechanism: LHC and Dark Matter Signals

description: We investigate the connection between the conservation of R-parity in supersymmetry and the Stueckelberg mechanism for the mass generation of the B-L vector gauge boson. It is shown that with universal boundary conditions for soft terms of sfermions in each family at the high scale and with the Stueckelberg mechanism for generating mass for the B-L gauge boson present in the theory, electric charge conservation guarantees the conservation of R-parity in the minimal B-L extended supersymmetric standard model. We also discuss non-minimal extensions. This includes extensions where the gauge symmetries arise with an additional U(1)_{B-L} x U(1)_X, where U(1)_X is a hidden sector gauge group. In this case the presence of the additional U(1)_X allows for a Z' gauge boson mass with B-L interactions to lie in the sub-TeV region overcoming the multi-TeV LEP constraints. The possible tests of the models at colliders and in dark matter experiments are analyzed including signals of a low mass Z' resonance and the production of spin zero bosons and their decays into two photons. In this model two types of dark matter candidates emerge which are Majorana and Dirac particles. Predictions are made for a possible simultaneous observation of new physics events in dark matter experiments and at the LHC.

description: In order to address the issue of limited data samples for the deployment of pre-trained models in unseen environments, this paper proposes a residual channel-based data augmentation strategy for Radio Frequency Fingerprint Identification (RFFI), coupled with a lightweight SimSiam contrastive learning framework. By applying least square (LS) and minimum mean square error (MMSE) channel estimations followed by equalization, signals with different residual channel effects are generated. These residual channels enable the model to learn more effective representations. Then the pre-trained model is fine-tuned with 1% samples in a novel environment for RFFI. Experimental results demonstrate that our method significantly enhances both feature extraction ability and generalization while requiring fewer samples and less time, making it suitable for practical wireless security applications.

Asymptotic and numerical modeling of magnetic field profiles in superconductors with rough boundaries and multi-component gas transport in PEM fuel cells
Creators: name: Lindstrom, Michael Robert
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a combination of two research projects in applied mathematics, which use the applied math techniques of numerical and asymptotic analysis to study real-world problems. The first problem is in superconductivity. This section is motivated by recent experimental results at the Paul Sherrer Institute. Here, we need to determine how the surface roughness of a superconductor influences the penetration properties of an externally applied magnetic field. We apply asymptotic analysis to study the influences, and then verify the accuracy - even going well-beyond the limits of the asymptotics - by means of computational approximations. Through our analysis, we are able to offer insights into the experimental results, and we discover the influence of a few particular surface geometries. The second problem is in gas diffusion. The application for this study is in fuel cells. We compare two gas diffusion models in a particular fuel cell component, the gas diffusion layer, which allows transport of reactant gases from channels to reaction sites. These two models have very different formulations and we explore the question of how they differ qualitatively in computing concentration changes of gas species. We make use of asymptotic analysis, but also use computational methods to verify the asymptotics and to study the models more deeply. Our work leads us to a deeper understanding of the two models, both in how they differ and what similarities they share.

description: The problem of expansion planning is the problem of determining the optimum size, time, and location of infrastructure that is required to be added into the system. In this thesis, an integrated and multi-area framework for expansion planning of electricity, heat, and gas infrastructure is developed with the objective of minimizing cost over the planning horizon. First, the expansion planning problem involving electricity and heat energy systems is modeled. This model finds a plan for future installation of electricity generation units, CHPs and boilers along with the optimal dispatch of existing and new facilities. Second, the model is further developed by including the gas infrastructure. Thus, a comprehensive expansion planning of the electricity generation and transmission, heat generation, gas production, gas pipelines, and gas storage is conducted. The simulation results on Alberta energy system indicate the proposed model outperforms the existing expansion planning models in terms of cost and emissions.
Resistência à colistina e sua disseminação: implicações em saúde pública

Publisher: name: Revista Portuguesa de Farmacoterapia
Year: 2018

description: A colistina é um antibiótico polipeptídico que foi extensivamente utilizado, a nível mundial, em medicina humana e veterinária, na década de 1960. Na medicina humana, a elevada incidência de nefrotoxicidade e de neurotoxicidade, desencadeou o declínio da utilização sistémica da colistina. Consequentemente, a colistina foi substituída por outros antibióticos menos tóxicos. No entanto, nas últimas décadas, o elevado número de surtos hospitalares provocados por bactérias Gram-negativo resistentes a múltiplos fármacos, levou os clínicos a re-introduzir a colistina sistémica, como fármaco de último recurso.

Até 2015, a resistência à colistina relacionava-se com a ocorrência de mutações cromossómicas, não havendo descrição da ocorrência de transferência horizontal de genes. Em novembro de 2015, na China, foi publicado, pela primeira vez, um caso de resistência à colistina codificado pelo gene mcr-1, localizado num plasmídeo. Em junho de 2016, na Bélgica, foi detetado outro gene de resistência à colistina mediada por plasmídeo, designado mcr-2. Após a sua divulgação, os genes foram detetados em amostras de animais produtores de alimentos, amostras clínicas humanas e fontes ambientais, em muitos países, o que indica uma disseminação global e ameaça ao tratamento de infeções multirresistentes.

description: Stainless steel-to-titanium bimetallic transitions have been fabricated with an explosively bonded joint. This novel joining technique was conducted by the Russian Federal Nuclear Center, working under contract for the Joint Institute for Nuclear Research. These bimetallic transitions are being considered for use in future superconducting radio-frequency cavity cryomodule assemblies. This application requires cryogenic testing to demonstrate that this transition joint remains leak-tight when sealing superfluid helium. To simulate a titanium cavity vessel connection to a stainless steel service pipe, bimetallic transition joints were paired together to fabricate piping assemblies. These piping assemblies were then tested in superfluid helium conditions at Fermi National Accelerator Laboratory test facilities. The transition joint test program will be described. Fabrication experience and test results will be presented.

description: In this thesis an integrated approach to predict the effective thermal conductivity of porous media is presented. A pore scale level heat transfer model is developed and used to generate a custom mixing rule for thermal conductivity prediction. The novel mixing rule is developed based on particle size distribution data for unconsolidated porous media. The fluid and solid phase are considered, with fluid phase being stagnant. The point contact between the grains and spherical shape of the grains are also assumed. The model and mixing rule are validated and sensitivity analysis is performed. The question of upscaling the results of pore scale level modeling is also addressed. Two approaches are presented: equivalent network model and upscaling using computer tomography images. Equivalent network model was validated using model-by-model validation approach. Computer tomography images upscaling approach was applied to predict the scaled up thermal conductivity of oil sand core samples.

description: Description:This research introduces a novel thermodynamic model of Earth's upper atmosphere, rooted in an interdisciplinary fusion of classical atmospheric physics, information theory, and magnetic field interaction. The work proposes the existence of thermal memory — a behavior whereby heat in the thermosphere is not merely dissipated but retained, aligned, and re-released in response to geomagnetic field structure.

The theoretical foundation integrates three core models:

Cold Vacuum Model (CVM): Interprets mass-energy systems as regulators of surrounding vacuum temperature through entropy emission.

Fundamental Conservation of Information (FCI): Reformulates the second law of thermodynamics through the lens of information preservation and entropy structuring.

Soft Magnetism Framework (SMF): Applies principles of soft magnetic hysteresis to field-aligned entropy flow in ionized atmospheric layers.

Using these combined frameworks, the thesis introduces Magnoentropene — a hypothesized transient field-responsive thermodynamic structure responsible for retaining heat in field-aligned domains. The model explains persistent post-sunset thermospheric heating, auroral thermal asymmetries, and entropy flow anomalies using a single unifying lens.

Numerical simulations demonstrate how the CVM/FCI framework reproduces real-world thermal lag behaviors observed by NASA's ICON and TIMED missions. Results are supported by parameter values from validated sources including IRI models, NOAA magnetic field data, and IR thermospheric radiometry.

Key outcomes and capabilities:

Simulated post-sunset temperature decay with entropy-aligned delay terms

Field-aligned entropy dispersion modeling and hysteresis behavior

Testable predictions using IR satellites, magnetometers, and machine learning-enhanced models

This thesis offers a testable, interdisciplinary model with potential implications for space weather forecasting, climate modeling, planetary habitability studies, and computational thermodynamics.
Identifying universality classes of absorbing phase transitions by block renormalization

description: We propose a renormalization scheme that can be used as a reliable method to identify universality classes of absorbing phase transitions. Following the spirit of Wilson's block-spin renormalization group, the lattice is divided into blocks, assigning to them an effective state by a suitable Boolean function of the interior degrees of freedom. The effective states of adjacent blocks form certain patterns which are shown to occur with universal probability ratios if the underlying process is critical. Measuring these probability ratios in the limit of large block sizes one obtains a set of universal numbers as an individual fingerprint for each universality class.

Year: 2018

description: O objectivo deste estudo foi encontrar um consenso relativamente às funções do farmacêutico clinico mais valorizadas pelos médicos de uma unidade de internamento de curta duração de um Serviço de Urgência.

O estudo foi realizado no Hospital Prof. Dr. Fernando Fonseca, E.P.E que serve 700 000 habitantes do concelho Amadora e Sintra. A uma equipa fixa de 13 clínicos aplicou-se, usando a técnica de Delphi, um questionário que avaliava as intervenções do Farmacêutico em dois momentos: intervenções detalhadas durante a admissão, internamento e alta do doente e apreciação geral do seu trabalho no serviço de Urgência. O questionário foi aplicado 3 vezes e cada perito valorizou a intervenção do farmacêutico de acordo com uma escala qualitativa de Likert. O consenso foi atingido em Abril/Maio de 2017.

Da aplicação do questionário obtiveram-se 21 indicadores com consenso, 12 relacionados com o momento da admissão e internamento e os restantes com a apreciação geral do trabalho do Farmacêutico. Os peritos valorizaram indicadores relativos à identificação de reacções adversas, de problemas com medicamentos de alto risco, de padrões incorrectos de prescrição, de problemas na distribuição do medicamento correcto e à necessidade de discussão de todos os problemas encontrados com o clínico. Algumas intervenções consideradas muito importantes do ponto de vista farmacêutico não foram valorizadas pelos clínicos como a reconciliação da terapêutica, a monitorização de parâmetros clínicos, a validação farmacêutica de antibióticos e a promoção da adesão à terapêutica. Os clínicos consensualmente referem que o Farmacêutico tem um impacto positivo nos resultados clínicos do doente e aumenta a eficiência, segurança e efectividade do medicamento, antecipando problemas.

O Farmacêutico Clínico do Serviço de Urgência tem um papel importante e é reconhecido dentro da sua equipa como um elemento que acrescenta valor à prática clínica.

Geometric morphometric analysis of the breast-shoulder apparatus of Greater Antillean anole ecomorphs

description: Anoline lizards of the Greater Antillean islands have repeatedly followed parallel paths of morphological adaptation, resulting in ecologically and morphologically similar ecomorph communities (ecomorphs) on each island. Locomotor performance has been shown to be a key factor related to differential microhabitat occupancy of anoles, but to date studies on possible differences in the form and configuration of the postcranial skeleton and musculature (deep anatomy) that relate to ecomorphological differentiation are scant. Here I employ the breast-shoulder apparatus (BSA; the skeleton, musculature, and connective tissue that comprise the pectoral region of tetrapods) to examine the morphological variability of the pectoral region of island anoles. I employ microcomputed tomography to image the skeletal elements of the BSA, and three-dimensional geometric morphometric analysis to compare the shapes of the skeletal features of twenty-six anole species representing four distinctive ecomorphs (trunk-ground, trunk-crown, crown-giant, twig). My material is sourced from three Greater Antillean islands (Jamaica, Puerto Rico, and Hispaniola). Despite several limitations of the techniques employed, I show that a comprehensive understanding of the interactions between ecological preferences and morphological adaptations can only be gained from an investigation of the complex integration of form, function, and ecological role. The geometry of the shoulder girdle in situ, and that of its components, differs between anole species. These morphological differences show a hierarchy of influences: they are primarily driven by ecomorph designation, but are also influenced by patterns of phylogenetic relationship, which contrasts with the findings from linear measurements and counts used to characterise ecomorphs. The three arboreal ecomorphs are characterised by a differential shape of the presternum, which is likely associated with changes in the musculature of these anoles, and made possible through the insensible transition between the pre- and mesosternum, facilitating migration of the rib attachment sites. This has potentially facilitated adaptive radiation in anoles. My investigations further show that linear external measurements cannot be employed to predict patterns of variation in the skeletal elements of the BSA. Varying environmental factors on the three islands examined allowed for the occurrence of similar, but not identical, skeletal patterns of ecological-morphological adaptation in geographically distinct areas.

The mill-site : Victorian processing in England and "Vancouver"; from Eliot to Marlatt
Creators: name: Woods, Derek John
Publisher: name: University of British Columbia
Year: 2010

description: This thesis explores the mill-site as a discursive, literary, and physical location. The philology of “mill” sets the focus on processing, which is described as a transformative action between nature and culture, one that nonetheless contributes to the ideological purification of those categories and to the construction of the “resource” as a formless reserve for consumption. The histories of power technologies (like mills) and their integration with ecologic and economic systems participate in determining the kind of relationship manifest between nature and culture. Noting the extension of the literal and figurative senses of “mill” to the processing of language, I also propose a notion of transcursivity to signal the transformation of language and symbolic additions to the activity of the mill-site. Chapter Two focuses on a reading of George Eliot’s novel The Mill on the Floss (1860), supplemented by an analysis of processing in Herman Melville’s story The Paradise of Bachelors and the Tartarus of Maids (1855) and Charles Dickens’ article “A Paper-Mill” (1850). I argue for the importance of mill and setting to Eliot’s novel, finding the mill to be an active force in the plot at several junctures; The Mill on the Floss, through its engagement with the relation between different economies and the relation of economy to ecology, can be considered a central text for the study of such themes in Victorian literature. Close analysis of the language of processing itself points to the importance of medial substances like fibre and grain to the construction of materials as “resources.” Chapter Three describes the Hastings Mill, located in various historiographies as the Victorian “origin” of the City of Vancouver. Through exploration of archival and published historical texts, I describe that mill’s originary intervention as a break in the system that alters the region’s economic/ecologic history. Daphne Marlatt’s novel Ana Historic (1988) depicts this historical origin and seeks to problematize its common narrative by reimagining ignored women’s histories and by queering the significance of this colonial mill-site. Marlatt elucidates problems of historical interpretation associated with the mill’s form of biopower, and its influence on relation of nature to culture.

description: Dripping water from a faucet is a typical example exhibiting rich nonlinear phenomena. For such a system, the time stamps at which water drops separate from the faucet can be directly observed in real experiments, and the time series of intervals τ_n between drop separations becomes a subject of analysis. Even if the mass m_n of a drop at the onset of the n-th separation, which cannot be observed directly, exhibits perfectly deterministic dynamics, it sometimes fails to obtain important information from time series of τ_n. This is because the return plot τ_n-1 vs. τ_n may become a multi-valued function, i.e., not a deterministic dynamical system. In this paper, we propose a method to construct a nonlinear coordinate which provides a "surrogate" of the internal state m_n from the time series of τ_n. Here, a key of the proposed approach is to use ISOMAP, which is a well-known method of manifold learning. We first apply it to the time series of $τ_n$ generated from the numerical simulation of a phenomenological mass-spring model for the dripping faucet system. It is shown that a clear one-dimensional map is obtained by the proposed approach, whose characteristic quantities such as the Lyapunov exponent, the topological entropy, and the time correlation function coincide with the original dripping faucet system. Furthermore, we also analyze data obtained from real dripping faucet experiments which also provides promising results.

description: We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally amplifies curvature perturbations at small scales via gravitationally enhanced friction, a mechanism critical for the formation of primordial black holes and the associated production of potentially detectable scalar-induced gravitational waves. We derive analytical expressions for the primordial power spectrum, enabling efficient exploration of the model parameter space without requiring computationally intensive numerical solutions of the Mukhanov-Sasaki equation. Using the third data release of the Parkes Pulsar Timing Array (PPTA DR3), we constrain the model parameters characterizing the coupling function: $ϕ_c = 3.7^{+0.3}_{-0.5} M_\mathrm{P}$, $\log_{10} ω_L = 7.1^{+0.6}_{-0.3}$, and $\log_{10} σ= -8.3^{+0.3}_{-0.6}$ at 90\% confidence level. Our results demonstrate the growing capability of pulsar timing arrays to probe early Universe physics, complementing traditional cosmic microwave background observations by providing unique constraints on inflationary dynamics at small scales.

description: The Rubber Hand Illusion (RHI) can be induced by synchronous brushing of a seen rubber hand and the subject’s real hidden hand. We sought to determine whether the RHI could be induced using one somatosensory modality and maintained using another. In 75 subjects, one of three modalities was used to induce the RHI: touch (brush), vibration (128Hz), or temperature (cooling). We then tested whether the illusion was maintained when only the rubber hand received stimuli from all modalities including kinesthesia (passive movement of arm). The RHI was successfully induced with touch, vibration and cooling modalities in 35 of 75 subjects. When only the seen rubber hand received a stimulus and not the hidden real hand, ownership persisted in 24 of 35 subjects who were successfully induced before. Our results may contribute to the understanding of the RHI and to the development of somatosensory neuroprosthetics.

description: We establish a condition for obtaining nonsingular potentials using the Cox-Thompson inverse scattering method with one phase shift. The anomalous singularities of the potentials are avoided by maintaining unique solutions of the underlying Regge-Newton integral equation for the transformation kernel. As a by-product, new inequality sequences of zeros of Bessel functions are discovered.

description: Introdução: Os medicamentos biológicos inovadores têm vindo a ser associados a preços galopantes que introduzem elevadas pressões nos orçamentos para a saúde. A adoção de medicamentos biossimilares permite aumentar o acesso dos doentes a terapias biológicas, oferecendo diversidade de opções de tratamento, atenuando as pressões orçamentais sobre os sistemas de saúde e libertando recursos que poderão ser investidos em outras áreas. Apesar destas vantagens, o mercado europeu dos biossimilares está longe de estar consolidado, existindo uma elevada variância de adoção entre Estados-Membro motivada pelo desconhecimento tido pelos vários intervenientes em relação às dinâmicas de mercado. O presente estudo propõe-se a identificar as principais dinâmicas que regem o mercado europeu dos biossimilares, determinando a influência das mesmas na quota de mercado obtida pelos diversos produtos aprovados ao longo de 10 anos.
Métodos: Realiza-se assim um estudo estatístico partindo de uma mostra de 22 países da União Europeia para os quais são selecionadas 11 dinâmicas de mercado (variáveis independentes) cuja correlação com a quota de mercado (variável dependente) é determinada através de regressão linear múltipla, com recurso ao método estatístico análise de variância (ANOVA).
Resultados: São obtidos três modelos matemáticos que constatam a influência de três dinâmicas na quota de mercado de um biossimilar nos mercados europeus.
Conclusão: Conclui-se que, para os mercados maturados (epoetina, filgrastim e somatropina), a quota de mercado de um biossimilar aumenta 0,7% por cada redução de preço em 1%, introduzida pelo biossimilar (no conjunto biossimilar e produto de referência), e diminui 12,9% por cada ano de presença de biossimilares da mesma classe num dado país e 16,3% por cada ano de atraso na entrada do biossimilar (face à autorização de introdução no mercado centralizada) num dado país.

description: Dementia is an incurable neurocognitive disorder and recognizing early pathological biomarkers can help to predict future dementia. Transient Ischemic Attack (TIA) and minor stroke patients are at risk of dementia. We hypothesized that TIA and minor stroke patients experience higher brain atrophy rates and that baseline brain and hippocampal volumes may predict cognitive decline at 3 years. Our results suggest that TIA and minor stroke patients experienced a higher percent brain atrophy rate over 3 years compared to controls. Cognitive decline was observed at 3 years for tests assessing processing speed, and short and long delay free recall. Age was a predictor of decline in processing speed and time was a predictor for short and long delay free recall as well. Higher whole-brain atrophy and cognitive decline at 3 years suggests that TIA/minor stroke patients are a high-risk population for dementia.
Evolutionary synthesis models as a tool and guide towards the first galaxies

description: We summarize the principles and fundamental ingredients of evolutionary synthesis models, which are stellar evolution, stellar atmospheres, the IMF, star-formation histories, nebular emission, and also attenuation from the ISM and IGM. The chapter focusses in particular on issues of importance for predictions of metal-poor and Population III dominated galaxies. We review recent predictions for the main physical properties and related observables of star-forming galaxies based on up-to-date inputs. The predicted metallicity dependence of these quantities and their physical causes are discussed. The predicted observables include in particular the restframe UV-to-optical domain with continuum emission from stars and the ionized ISM, as well as emission lines from H, He, and metals. Based on these predictions we summarize the main observational signatures (emission line strengths, colors etc.), which can be used to distinguish "normal" stellar populations from very metal-poor objects or even Pop III. Evolutionary synthesis models provide an important and fundamental tool for studies of galaxy formation and evolution, from the nearby Universe back to first galaxies. They are used in many applications to interpret existing observations, to predict and guide future missions/instruments, and to allow direct comparisons between state-of-the-art galaxy simulations and observations.

An Ancient Metal-Poor Population in M32, and Halo Satellite Accretion in M31, Identified by RR Lyrae Stars

description: We present time-series photometry of two fields near M32 using archival observations from ACS/WFC onboard HST. One field is centered about 2 arcmin from M32 while the other is located 15 arcmin to the southeast of M31. We identify a total of 1139 RR Lyrae variables of which 821 are ab-type and 318 are c-type. In the field near M32, we find a radial gradient in the density of RR Lyraes relative to the center of M32. This gradient is consistent with the surface brightness profile of M32 suggesting that a significant number of the RR Lyraes in this region belong to M32. This provides further confirmation that M32 contains an ancient stellar population formed around the same time as the oldest population in M31 and the Milky Way. The RR Lyrae stars in M32 exhibit a mean metal abundance of [Fe/H] ~ -1.42 +/- 0.02, which is ~15 times lower than the metal abundance of the overall M32 stellar population. Moreover, the abundance of RR Lyrae stars normalized to the luminosity of M32 in the field analyzed further indicates that the ancient metal-poor population in M32 represents only a very minor component of this galaxy, consistent with the 1% to 4.5% in mass inferred from the CMD analysis of Monachesi et al. In the other field, we find unprecedented evidence for two populations of RR Lyraes in M31 as shown by two distinct sequences among the ab-type variables in the Bailey Diagram. When interpreted in terms of metal abundance, one population exhibits a peak at [Fe/H] ~ -1.3 and the other is at [Fe/H] ~ -1.9. One possible interpretation of this result is that the more metal-rich population represents the dominant M31 halo, while the metal-poorer group could be a disrupted dwarf satellite galaxy orbiting M31. If true, this represents a further indication that the formation of the M31 spheroid has been significantly influenced by the merger and accretion of dwarf galaxy satellites. [abridged]

Toward a Deeper Awareness: Becoming a Mindful Educational Leader

Subjects: subject: Education
subject: Mindfulness
subject: Leadership

description: This study explored the meditative practice and non-meditative process of mindfulness and its application to educational leadership. The definition of mindfulness that guided this research was – being attentive and aware in the present moment. Mindfulness was viewed as being more than meditation; it was seen as clear comprehension of a situation and being prepared and willing to address whatever happened. It was a way of understanding one’s self and one’s self in relation to others and the world. The purpose of this research was to construct a conceptualization of mindful educational leadership. This Scholarly Personal Narrative (Nash, 2004; Nash & Bradley, 2011; Nash & Viray, 2013) study provided a conceptualization of what it means to be a mindful educational leader. The conceptualization came from the application of a review: of mindfulness; of leadership as expressed in a way closest to mindfulness, and through the application of Scholarly Personal Narrative to the researcher’s experiences as an educational leader, and as a participant in major life-changing events. Data collection included: epistolary letters, journal reflections, as well as narrative and poetic life texts. A parallax vantage analysis was utilized to uncover and identify universalizable themes within the narrative. These themes offered an understanding of the duality of mindfulness (awareness of self and others) that was linked to the duality of leadership that, at its base, is about the leader and the follower, and thus it is both self and relational. The resulting construct of mindful educational leadership would fill a gap in the academic literature on leadership and would offer to educational leaders, a reflective and purposeful way of being in the world.
