Observationally-Motivated Analysis of Simulated Galaxies
The spatial and temporal relationships between stellar age, kinematics, and
chemistry are a fundamental tool for uncovering the physics driving galaxy
formation and evolution. Observationally, these trends are derived using
carefully selected samples isolated via the application of appropriate
magnitude, colour, and gravity selection functions of individual stars;
conversely, the analysis of chemodynamical simulations of galaxies has
traditionally been restricted to the age, metallicity, and kinematics of
`composite' stellar particles comprised of open cluster-mass simple stellar
populations. As we enter the Gaia era, it is crucial that this approach
changes, with simulations confronting data in a manner which better mimics the
methodology employed by observers. Here, we use the \textsc{SynCMD} synthetic
stellar populations tool to analyse the metallicity distribution function of a
Milky Way-like simulated galaxy, employing an apparent magnitude plus gravity
selection function similar to that employed by the RAdial Velocity Experiment
(RAVE); we compare such an observationally-motivated approach with that
traditionally adopted - i.e., spatial cuts alone - in order to illustrate the
point that how one analyses a simulation can be, in some cases, just as
important as the underlying sub-grid physics employed.Comment: Accepted for publication in PoS (Proceedings of Science): Nuclei in

Biometric Data and Bone Identification of Topmouth Gudgeon Pseudorasbora Parva and Sunbleak Leucaspius Delineatus
Identification and analysis of the size and composition of prey taken by piscivorous predators assists in the further understanding of ecology of piscivorous fauna (Mann & Beaumont 1980, Hansel et al. 1988, Copp & Roche 2003). Comprehensive evaluation of the digested prey is central to the assessment of predation impacts and is equally important for sustainable fisheries management. Two non-native fish species in England that may be potential prey for native species are sunbleak Leucaspius delineatus (Heckel) and topmouth gudgeon Pseudorasbora parva (Temminck et Schlegel). These species were introduced to English waters in the mid 1980’s (Farr - Cox 1996, Gozlan et al. 2002) where they have since developed extensive populations (Gozlan et al. 2003, Hickley & Chare 2004). Recent studies associate sunbleak and topmouth gudgeon with novel non-native parasites (Beyer et al. 2005, Gozlan et al. 2005). Results such as these have emphasized the need to be able to identify these two species as part of the native predators’ diet. The aim of the study was to provide a tool for species identification and to elaborate the biometric relationships between bone dimensions and body size of sunbleak and topmouth gudgeon. Head bones of fish are particularly useful for identifying the size and composition of prey species from the food remains of predators, as they withstand digestion and are
taxonomically valuable (Copp & Kováč 2003)
Strongly Inhomogeneous Phases and Non-Fermi Liquid Behavior in Randomly Depleted Kondo Lattices
We investigate the low-temperature behavior of Kondo lattices upon random
depletion of the local -moments, by using strong-coupling arguments and
solving SU() saddle-point equations on large lattices. For a large range of
intermediate doping levels, between the coherent Fermi liquid of the dense
lattice and the single-impurity Fermi liquid of the dilute limit, we find
strongly inhomogeneous states that exhibit distinct non-Fermi liquid
characteristics. In particular, the interplay of dopant disorder and strong
interactions leads to rare weakly screened moments which dominate the bulk
susceptibility. Our results are relevant to compounds like Ce_{x}La_{1-x}CoIn_5
and Ce_{x}La_{1-x}Pb_3Comment: 4 pages, 5 figure
Probing neutrino transition magnetic moments with coherent elastic neutrino-nucleus scattering
We explore the potential of current and next generation of coherent elastic
neutrino-nucleus scattering (CENS) experiments in probing neutrino
electromagnetic interactions. On the basis of a thorough statistical analysis,
we determine the sensitivities on each component of the Majorana neutrino
transition magnetic moment (TMM), , that
follow from low-energy neutrino-nucleus experiments. We derive the sensitivity
to neutrino TMM from the first CENS measurement by the COHERENT
experiment, at the Spallation Neutron Source. We also present results for the
next phases of COHERENT using HPGe, LAr and NaI[Tl] detectors and for reactor
neutrino experiments such as CONUS, CONNIE, MINER, TEXONO and RED100. The role
of the CP violating phases in each case is also briefly discussed. We conclude
that future CENS experiments with low-threshold capabilities can improve
current TMM limits obtained from Borexino data.Comment: 25 pages, 8 figures, 2 tables, analysis updated; conclusions

Propagação vegetativa do mogno (Swietenia macrophylla King) por enraizamento de estacas semilenhosas em câmara úmida.
A exploração predatória do mogno representa uma ameaça à sobrevivência da espécie, provocando a destruição da maior parte do germoplasma, especialmente daquelas árvores com as características mais desejáveis para a produção de madeira, às quais representam alto potencial de conservação "in situ" como plantas matrizes. Diante desta realidade e dada a importância da espécie para a produção de madeira de alto valor, são necessários estudos com o objetivo de desenvolver um método prático de reprodução vegetativa para estabelecer uma estratégia de conservação e reprodução do germoplasma de melhor qualidade. Entre os métodos de propagação vegetativa recomendados a espécies tropicais para produção de madeira, destaca-se o enraizamento de estacas semilenhosas em câmara úmida. O objetivo deste trabalho foi determinar a eficiência de diferentes substratos e concentração de ácido indolbutírico (AIB) no enraizamento de estacas semilenhosas de S. macrophylla, utilizando uma câmara propagadora de subirrigação.bitstream/item/164612/1/3990.pd
Application of Lymphedema Education Toolkit for Nurse Coordinators
Problem: There is approximately one in five breast cancer survivors affected by breast cancer-related lymphedema (BCRL), a potentially debilitating condition affecting the physical, emotional, social, and financial well-being of individuals. Context: This Quality Improvement (QI) project was conducted at an outpatient facility of Hospital X’s Women’s Cancer Center. Within this microsystem, there are 24 permanent clinical nurse coordinators and advanced practice providers, with 15 nurse coordinators dedicated to care for patients with breast cancer or gynecological conditions. Intervention: The intervention aims to evaluate if a standardized educational tool improves early interventions for patients with lymphedema and knowledge among healthcare providers on the comprehension of lymphedema stages, diagnostic modalities, risk reduction, and treatments. By implementing this toolkit for nurse coordinators, intervention helps assist patients make informed decisions about their care. Measures: Data collection gathered evidence-based research to improve early lymphedema interventions compared to current methods. The application of a pre-and post-survey assesses stakeholder’s efficacy of the education toolkit. Results: A pre-assessment survey evaluating the effectiveness of an education toolkit achieved an 81% response rate, and the post-assessment survey had an average score of 93%. To institute early interventions for patients the average response rate improved by 12% after implementing a standardized education tool for nurse coordinators. Conclusion: In the transition of the change process of this microsystem, an increase in knowledge following the implementation of a standardized toolkit enhanced early interventions for patients and clinical nurse coordinators at Hospital X Women’s Cancer Center
