description: Important efforts are currently made for understanding the so-called kinetic instabilities, driven by the anisotropy of different species of plasma particles present in the solar wind and terrestrial magnetosphere. These instabilities are fast enough to efficiently convert the free energy of plasma particles into enhanced (small-scale) fluctuations with multiple implications, regulating the anisotropy of plasma particles. In this paper we use both linear and quasilinear (QL) frameworks to describe complex unstable regimes, which realistically combine different temperature anisotropies of electrons and ions (protons). Thus parameterized are various instabilities, e.g., proton and electron firehose, electromagnetic ion cyclotron, and whistler instability, showing that their main linear properties are markedly altered by the interplay of anisotropic electrons and protons. Linear theory may predict a strong competition of two instabilities of different nature when their growth rates are comparable. In the QL phase wave fluctuations grow and saturate at different levels and temporal scales, by comparison to the individual excitation of the proton or electron instabilities. In addition, cumulative effects of the combined proton and electron induced fluctuations can markedly stimulate the relaxations of their temperature anisotropies. Only whistler fluctuations inhibit the efficiency of proton firehose fluctuations in the relaxation of anisotropic protons. These results offer valuable premises for further investigations in numerical simulations, to decode the full spectrum of kinetic instabilities resulting from the interplay of anisotropic electrons and protons in space plasmas.

description: The specific factors that influence spatial community or population dynamics are often elusive, and even less known is the impact of tropical urban landscapes on diverse species community assemblages. To address this knowledge gap, we used a survey data set with 510 fruit‐feeding butterflies comprising 20 species across two heterogeneous habitats within a city in Nigeria. Next, we constructed generalised linear mixed models to understand the differential responses of the butterfly community to changes in environmental conditions across habitats. Butterfly species community assemblages significantly differed between the two urban habitats, with butterfly species significantly higher in the savannah woodland compared with the gallery forest due to the optimal daily temperatures of the savannah woodland. However, butterfly richness was lower in the gallery forest due to extreme environmental conditions. This study highlights that butterfly community changes in tropical urban landscapes are possibly responding to local microclimates and spatial heterogeneity across habitats. For evidence‐based conservation management of tropical butterfly biodiversity, there would be a need for a long‐term, extensive and systematic insect monitoring programme for butterflies across disturbed and undisturbed fragmented habitats harbouring diverse insect species.

Perception of social support in adolescence : the impact of a stress-management intervention
Creators: name: Seigo, Nancy L.
Publisher: name: University of British Columbia
Year: 2009

description: A stress-management intervention for adolescents called the Coping Skills Program (Madden, James, & Paton, Australia, 1994) was replicated in order to test the generalizability to Canadian adolescents. A social support component was added to inform adolescents about the advantages of seeking social support in times of stress and to increase their awareness of support systems that are available. This study examined the impact of the stress intervention on perceptions of social support from family and friends and on social support coping. The participants (32 females and 25 males) were grade 9 students assigned to one of two treatment groups or a control group. Two treatment conditions were compared, a skills intervention (Skills) and a knowledge intervention (Knowledge). The intervention program consisted of five 50-minute sessions conducted over 5 weeks. Perceived Social Support from Family (Procidano & Heller, 1983), Perceived Social Support from Friends (Procidano & Heller, 1983) and the Coping Questionnaire for Adolescents (Madden, James, Paton, & King, 1992) were administered at pre, post and 6 month follow-up. It was predicted that levels of perceived support from family and friends and the relative use of social support coping would increase from pretest to posttest for both treatment conditions compared with the control group and that the Skills group would maintain these increases from posttest to follow-up. The results indicated that there was a significant Group X Time interaction from pretest to posttest for both the Perceived Social Support from Friends and Perceived Social Support from Family measures, and from posttest to follow-up for the Perceived Social Support from Friends. When the mean scores were examined, the direction of change was generally opposite to the hypothesized direction of change resulting in rejection of the hypothesis. There was a moderate and significant correlation between posttest scores of social support coping and follow-up scores of perceived social support from family. These results indicate that greater use of social support coping predicted an increase in the perceived support felt. Implications for theory and practice are discussed.

description: We study the branching ratios of the lepton flavor violating processes μ-> eγ, τ-> eγand τ-> μγby considering that the new Higgs scalars localize with Gaussian profile in the extra dimension. We see that the BRs of the LFV decays μ-> e γ, τ-> e γand τ-> μγare at the order of the magnitude of 10^{-12}, 10^{-16} and 10^{-12} in the considered range of the free parameters. These numerical values are slightly suppressed in the case that the localization points of new Higgs scalars are different than origin.

description: Virtual musicians have become a remarkable phenomenon in the contemporary multimedia arts. However, most of the virtual musicians nowadays have not been endowed with abilities to create their own behaviors, or to perform music with human musicians. In this paper, we firstly create a virtual violinist, who can collaborate with a human pianist to perform chamber music automatically without any intervention. The system incorporates the techniques from various fields, including real-time music tracking, pose estimation, and body movement generation. In our system, the virtual musician's behavior is generated based on the given music audio alone, and such a system results in a low-cost, efficient and scalable way to produce human and virtual musicians' co-performance. The proposed system has been validated in public concerts. Objective quality assessment approaches and possible ways to systematically improve the system are also discussed.
Multi Domain Anomaly Detection in Spatial Datasets

description: A spatial anomaly captures a phenomenon occurring in a region which is vastly deviant in behavior with respect to the other normal observations. However, in reality this anomaly may impact other phenomena in the region across multiple domains, for example crime is often linked to other socio political factors or phenomenon such as poverty and education. So, finding anomalies across multiple domains is important in various applications. In this thesis, we propose an approach for finding such a tangible anomalous window across multiple domains where window refers to the set of continuous point in space, since the window is multi domain there are several overlapping windows in the same space across domains. We provide detailed experimental results using real world health ranking and transportation datasets. The results show that our approach is effective in finding the anomalies in multiple domains.

description: The architectural semantics of \emph{Information-Centric Networking} bring in interesting features in regards to mobility management: Information-Centric Networking is content-oriented, connection-less, and receiver-driven. Despite such intrinsic advantages, the support for node movement is being based on the principles of IP solutions. IP-based solutions are, however, host-oriented, and Information-Centric Networking paradigms are information-oriented. By following IP mobility management principles, some of the natural mobility support advantages of Information-Centric Networking are not being adequately explored. This paper contributes with an overview on how Information-Centric Networking paradigms handle mobility management as of today, highlighting current challenges and proposing a set of design guidelines to overcome them, thus steering a vision towards a content-centric mobility management approach.
Structural Characterization of the Minimal HIV-1 Psi- RNA Packaging Signal and Potential Psi-site Interactions within the 5'-UTR

description: The 5'-untranslated region (5'-UTR) of the human immunodeficiency virus type-1 (HIV-1) genome regulates multiple RNA-dependent functions during viral replication and has been proposed to adopt multiple secondary structures.  HIV-1 was thought to package its genome by specific interactions between the nucleocapsid (NC) domain of Gag and a ~120 nucleotide region of the unspliced viral RNA located within the 5'-UTR, known as the psi-site.  Extensive site-directed mutagenesis, chemical modification, nuclease accessibility mapping, and free energy computational studies indicate that the HIV-1 psi-site contains four stemloop structures designated SL1 through SL4, connected by relatively short linkers.  All four stemloops are important to achieve wildtype packaging levels.  We have completed NMR assignments for the intact HIV-1 psi-site stemloops and no long-range inter-stem NOE's were observed that would indicate an overall tertiary structure or fold that differs from the individual stemloop structures.  Therefore, some other interaction must exist to explain the dimer dependent packaging of the HIV-1 genome.  Recent phylogenetic studies identified base pair complementarity between residues of the unique 5' (U5) element and those near the gag start codon (gagAUG< nserved among evolutionarily distant retroviruses, suggesting a potential long-range RNA-RNA interaction.  However, nucleotide accessibility studies led to conflicting conclusions about the presence of such interactions in virions and in infected cells.  Here we show that an 11-nucleotide oligo-RNA containing residues 105-115 of U5 (U5LINK< nds to oligoribonucleotides containing the gag start codon (AUG), disrupting a pre-existing stemloop and forming a heteroduplex stabilized by 11 Watson-Crick base pairs.  Addition of the HIV-1 nucleocapsid protein, the trans-acting viral factor required for genome packaging, disrupts the heteroduplex by binding tightly to U5LINK< ? 10nM at [NaCl] =100mM).  The structure of the NC:U5LINK< termined by NMR, exhibits features similar to those observed in NC complexes with HIV-1 stemloop RNAs, including the insertion of guanosine nucleobases to hydrophobic clefts on the surface of the zinc fingers and a 3'-to-5' orientation of the RNA relative to protein.  Our findings indicate that previously proposed long-range U5-gagAUG< s are feasible, and suggest a potential NC-dependent mechanism for modulating the structure of the 5'-UTR.
Toward Designing with Heterogeneous Values—A Graph Data Representation for Constructive Problem Framing in Multi-Objective Street Design

description: The process of urban design can be viewed as complex negotiations among heterogeneous value agendas representing different stakeholders. As a result, any urban design problem can yield a multitude of framings, each delineates a distinct approach to address its underlying objectives. Planners and designers frequently face the unwieldy challenge of the growing complexity of design problems, characterized by a large set of interwoven and often competing objectives.Shrouded in complex objectives and uncertainty, how can representations of design strategies provide affordance in the framing of urban design problems? Focused on multi-objective street design as the principle subject of investigation, this thesis proposed a representation of design strategies, integrating Object Process Methodology, Dynamic Bayesian Network, and graph data modeling. Subsequent experiments demonstrated that a design strategy represented as system architecture can encode the framing of its value propositions. The incorporation of Bayesian inference can meaningfully compute uncertainties in both the design and its context while supporting evidence-based belief-update. Finally, a graph data model can afford computational analyses that unveil latent interactions between different value framings, synergistic or conflicting, thus informs the reformulation of the design problem.

description: While the question of how to use human knowledge to guide evolutionary search is long-recognized, much remains to be done to answer this question adequately. This dissertation aims to further answer this question by exploring the role of domain knowledge in evolutionary computation as applied to real-world, complex problems, such as financial investing. The hypothesis is that domain knowledge can be combined with evolutionary algorithms (EAs) so as to systematically influence the traversal of a search space. A framework for incorporating domain knowledge into memetic algorithms, a specific kind of EAs, is proposed and is empirically evaluated by experiments that focus on knowledge-guided pre-processing, representation/initialization, and reproduction.  Knowledge can be incorporated into an EA adaptedly (e.g., pre-processing and initialization) or adaptively (e.g., representation and reproduction). From the adapted perspective, knowledge can facilitate data collection and data cleansing in the preprocessing phase. Knowledge can also be utilized to create the initial population. From the adaptive perspective, individuals are represented by a sequence of components (or building blocks) that are mappable to the nodes in a semantic net, on which mutation and crossover are conducted. The mutation changes components to ones based on a certain semantic distance or more dynamically, based on a function of semantic distance. The crossover swaps the building blocks between two fit individuals, where the crossover point is constrained to be the boundary of these building blocks. The test problems are asset valuation and portfolio optimization. The experimental results show that knowledge can systematically influence the traversal of a search space. More interestingly, the results show how conceptual distance in human knowledge can correspond to distance between evolutionary individuals. According to the problems being solved, knowledge might be dynamically used to increase or decrease the reproduction size in a search algorithm. These results shed light on the role of knowledge in EAs and are part of the larger body of work in the field of evolutionary computation to delineate how domain knowledge might usefully constrain EAs.

description: This dissertation provides an in-depth investigation, analysis, and critique of natural and human systems involving vacant land in neighborhoods of Southwest Baltimore City, Maryland. Using an interdisciplinary framework of theoretical, conceptual, and methodological approaches from urban ecology, political ecology, and environmental justice, this dissertation challenges popular notions from academia, science, policy, and social justice concerning vacant land in distressed inner-city neighborhoods. By challenging these notions, the dissertation aims to advance intellectual and theoretical perspectives about nature, community, safety, and health of these communities.             In order to provide a foundation for understanding the interdisciplinary nature of this dissertation, the dissertation discusses challenges, barriers, and opportunities related to designing and conducting interdisciplinary research. After laying this foundation, the chapters of the dissertation are presented under the theme of Ownership, Responsibility, and Vacant Lot Management. With respect to this theme, the chapters explore topics related to ecological, social, economic, and political systems associated with disinvested communities of Southwest Baltimore City, Maryland. In each of the chapters, meanings for ecology, environment and nature are explored in the context of ownership and responsibility for vacant land. The final chapter of the dissertation provides an interdisciplinary analysis of key findings and conclusions regarding the ecological, social and political landscape of disinvestment and the potential for procedural justice for Southwest Baltimore.

description: Context. FU Orionis is the archetypal FUor star, a subclass of young stellar object (YSO) that undergo rapid brightening events, often gaining 4-6 magnitudes on timescales of days. This brightening is often associated with a massive increase in accretion; one of the most ubiquitous processes in astrophysics from planets and stars to super-massive black holes. We present multi-band interferometric observations of the FU Ori circumstellar environment, including the first J-band interferometric observations of a YSO. Aims. We investigate the morphology and temperature gradient of the inner-most regions of the accretion disk around FU Orionis. We aim to characterise the heating mechanisms of the disk and comment on potential outburst triggering processes. Methods. Recent upgrades to the MIRC-X instrument at the CHARA array allowed the first dual-band J and H observations of YSOs.Using baselines up to 331 m, we present high angular resolution data of a YSO covering the near-infrared bands J, H, and K. The unprecedented spectral range of the data allows us to apply temperature gradient models to the innermost regions of FU Ori. Results. We spatially resolve the innermost astronomical unit of the disk and determine the exponent of the temperature gradient of the inner disk to $T=r^{-0.74\pm0.02}$. This agrees with theoretical work that predicts $T = r^{-0.75}$ for actively accreting, steady state disks, a value only obtainable through viscous heating within the disk. We find a disk which extends down to the stellar surface at $0.015\pm0.007$ au where the temperature is found to be $5800\pm700$ K indicating boundary layer accretion. We find a disk inclined at $32\pm4^\circ$ with a minor-axis position angle of $34\pm11^\circ$.

description: We report new calculations of interstellar 15N fractionation. Previously, we have shown that large enhancements of 15N/14N can occur in cold, dense gas where CO is frozen out, but that the existence of an NH + N channel in the dissociative recombination of N2H+ severely curtails the fractionation. In the light of recent experimental evidence that this channel is in fact negligible, we have reassessed the 15N chemistry in dense cloud cores. We consider the effects of temperatures below 10 K, and of the presence of large amounts of atomic nitrogen. We also show how the temporal evolution of gas-phase isotope ratios is preserved as spatial heterogeneity in ammonia ice mantles, as monolayers deposited at different times have different isotopic compositions. We demonstrate that the upper layers of this ice may have 15N/14N ratios an order of magnitude larger than the underlying elemental value. Converting our ratios to delta-values, we obtain delta(15N) > 3,000 per mil in the uppermost layer, with values as high as 10,000 per mil in some models. We suggest that this material is the precursor to the 15N `hotspots' recently discovered in meteorites and IDPs

description: The increase in the amount of data generated by modern technologies has resulted in an increasing need for context awareness. Context provides the boundaries within which we can transition from data to relevant information although context may not be explicitly present in the data itself. The interpretation of data which leads to the extraction of information, changes or varies when the context changes. In this thesis we examine data and create a contextual model that seamlessly combines data elements of a domain in order to effectively locate and provide the most appropriate information for the user according to his or her needs. Much of this contextual information becomes specialized or tailored to one special domain or environment and hence becomes completely unusable for other domains or environments. We propose a generic system design for modeling and representing any contextual model for any domain. We also propose and implement an automatic solution for creating contextual models for a particular domain or a business environment. We demonstrate the use of contextual information and semantic techniques with the implementation of a prototype in the application domain of identifying potential threats associated with the shipments from the perspective of U.S. Federal agencies. We implemented a set of tools and technologies to assist in the process of creation of a contextual model as well as semantic networks. The experimental evaluation of our methodology shows that our techniques are promising and they produce better precision results compared to the scenario when these techniques are not considered.

description: We have performed the first three-dimensional non-linear simulation of the turbulent convective envelope of a rotating 0.8 Msun RGB star using the ASH code. Adopting a global typical rotation rate of a tenth of the solar rate, we have analyzed the dynamical properties of the convection and the transport of angular momentum within the inner 50% in radius of the convective envelope. The convective patterns consist of a small number of large cell, associated with fast flows (about 3000 m/s) and large temperature fluctuations (about 300 K) in order to carry outward the large luminosity (L* = 400 Lsun) of the star. The interactions between convection and rotation give rise to a large radial differential rotation and a meridional circulation possessing one cell per hemisphere, the flow being poleward in both hemisphere. By analysing the redistribution of angular momentum, we find that the meridional circulation transports the angular momentum outward in the radial direction, and poleward in the latitudinal direction, and that the transport by Reynolds stresses acts in the opposite direction. From this 3-D simulation, we have derived an average radial rotation profile, that we will ultimately introduce back into 1-D stellar evolution code.

description: When the two dimensional q-color Potts model in the square lattice is quenched at zero temperature with Glauber dynamics, the energy decreases in time following an Allen-Cahn power law, and the system converges to a phase with energy higher than the ground state energy after an arbitrary large time when q>4. At low but finite temperature, it cesses to obey the power-law regime and orders after a very long time, which increases with q, and before which it performs a domain growth process which tends to be slower as q increases. We briefly present and comment numerical results on the ordering at nonzero temperature.

description: In recent years, there has been a growing desire among natural resource mangers to maintain and promote biodiversity in the built environment.  Though some management practices are implemented extensively in developed landscapes, their ecological implications are not currently known.  The goal of this study was to determine the effects of both dispersal and spatial variation in habitat conditions on biodiversity in urban zooplankton metacommunities.  A five-week mesocosm experiment was performed in which human management and elevated zooplankton dispersal rates were manipulated in a series of four-pond metacommunities.  Results indicate that dispersal had a significant negative effect on species turnover between communities but did not significantly affect local richness.  It was also demonstrated that dispersal and the interaction of the dispersal and management treatments could significantly affect zooplankton density.  These results highlight the importance of understanding the complex effects of dispersal and human management regimes on maintaining biodiversity in urban environments.

description: Texts obtained from web are noisy and do not necessarily follow the orthographic sentence and word boundary rules. Thus, sentence segmentation and word tokenization systems that have been developed on well-formed texts might not perform so well on unedited web texts. In this paper, we first describe the manual annotation of sentence boundaries of an Estonian web dataset and then present the evaluation results of three existing sentence segmentation and word tokenization systems on this corpus: EstNLTK, Stanza and UDPipe. While EstNLTK obtains the highest performance compared to other systems on sentence segmentation on this dataset, the sentence segmentation performance of Stanza and UDPipe remains well below the results obtained on the more well-formed Estonian UD test set.

Magnetic Fields of F-Type Stars

description: Magnetic fields are an observable feature of many stars, with warm, F-type stars of interest in searching for the transition from the fossil fields in hot stars to dynamos in cool stars driven by convection zones. Thus, this thesis presents an observational survey of F-type stars close to the expected transition between fossil and dynamo magnetic fields. A magnetic snapshot survey of 55 targets resulted in 14 magnetic field detections, across every spectral class from F3V-F9V ranging in strength from 0.3±0.1G (36 UMa, F8V) to 8.3±0.9 G (h Dra, F8V). These results are followed up with detailed mapping using Zeeman Doppler Imaging (ZDI) of the large-scale surface magnetic fields for four of these stars, β CrB, σ Boo, θ Dra, and β Vir. On the hot side of the suspected transition zone, β CrB (A9) shows a relatively complex, but stable topology which is not common for a fossil field and is more complex than a dipole. On the cool side of the suspected transition zone, the surface magnetic field of σ Boo (F3V) shows a relatively simple field topology with a dominant dipole structure. This is the first magnetic map for an F3 star and provides an opportunity to study magnetism in a star with an outer convection zone thickness less than three per cent of the stellar radius. ZDI maps are also presented for two late F-stars, θ Dra (F8IV) and β Vir (F9V). These two late F-stars are contrasted with σ Boo, and show a more complex magnetic topology. There are differences in complexity of the magnetic field between θ Dra and β Vir, which is possibly related to an increased rotation rate for θ Dra which shows more detail due to a greater surface resolution. The ZDI maps are also used in modelling the stellar winds. While definitive evidence of the transition from fossil to dynamo field is not clear from the single-epoch magnetic map results obtained, this work suggests additional future maps obtained across different epochs will provide empirical evidence for how stellar mass, rotation and age drive the emergence of dynamo fields in stars with shallow convection zones.

description: Besides structure function measurements and jet physics, there is a lively collection of more specific QCD analyses at HERA. In this contribution we present three-jet angular correlations and subjet distributions measured in ep collisions with the ZEUS detector. The angular correlations provide sensitivity to the color factors of the underlying gauge group and thus facilitate tests of basic properties of the strong interaction. The subjet distributions allow tests of the QCD radiation pattern within a jet in the perturbative regime.

description: In medical studies, it is common the presence of a fraction of patients who do not experience the event of interest. These patients are people who are not at risk of the event or are patients who were cured during the research. The proportion of immune or cured patients is known in the literature as cure rate. In general, the traditional existing lifetime statistical models are not appropriate to model data sets with cure rate, including bivariate lifetimes. In this paper, it is proposed a bivariate model based on a defective Gompertz distribution and also using a Clayton copula function to capture the possible dependence structure between the lifetimes. An extensive simulation study was carried out in order to evaluate the biases and the mean squared errors for the maximum likelihood estimators of the parameters associated to the proposed distribution. Some applications using medical data are presented to show the usefulness of the proposed model.
Breakdown of staggered fermions at nonzero chemical potential

description: The staggered fermion determinant is complex when the quark chemical potential mu is nonzero. Its fourth root, used in simulations with dynamical fermions, will have phase ambiguities that become acute when Re mu is sufficiently large. We show how to resolve these ambiguities, but our prescription only works very close to the continuum limit. We argue that this regime is far from current capabilities. Other procedures require being even closer to the continuum limit, or fail altogether, because of unphysical discontinuities in the measure. At zero temperature the breakdown is expected when Re mu is greater than approximately half the pion mass. Estimates of the location of the breakdown at nonzero temperature are less certain.

On Universal Constants of AdS Black Holes from Hawking-Page Phase Transition

description: We investigate the thermodynamic properties of the Hawking-Page phase transition of AdS black holes. We present evidence for the existence of two universal critical constants associated with the Hawking-Page (HP) and minimum black hole thermodynamical transition points. These constants are defined by C_S =\frac{S_{HP}-S_{min}}{S_{min}} and C_T =\frac{T_{HP}-T_{min}}{T_{min}} where S_{min}(S_{HP}) and T_{min}(T_{HP}) are the minimal (HP phase transition) entropy and temperature, respectively, below which no black hole can exist. For a large class of four dimensional non-rotating black holes, we find C_S =2 and C_T = \frac{2-\sqrt{3}}{\sqrt{3}}. For the rotating case, however, such universal ratios are slightly affected without losing the expected values. Taking small values of the involved rotating parameter, we recover the same constants. Higher dimensional models, with other universal constants, are also discussed in some details.

description: The recently proposed reduction method for diluted spin glasses is investigated in depth. In particular, the Edwards-Anderson model with \pm J and Gaussian bond disorder on hyper-cubic lattices in d=2, 3, and 4 is studied for a range of bond dilutions. The results demonstrate the effectiveness of using bond dilution to elucidate low-temperature properties of Ising spin glasses, and provide a starting point to enhance the methods used in reduction. Based on that, a greedy heuristic call ``Dominant Bond Reduction'' is introduced and explored.

Kepler-411 Differential Rotation from Three Transiting Planets

description: The differential rotation of the Sun is a crucial ingredient of the dynamo theory responsible for the generation of its magnetic field. Currently, the rotation profile of a star that hosts one or more transiting planets can be estimated. By detecting the same spot in a later transit, it is possible to infer the stellar rotation period at that latitude. In this work, we apply for the first time transit spot mapping to determine the differential rotation of Kepler-411, a K2V-type star with an average rotation period of 10.52 days, radius of 0.79 R$_\odot$ and mass of 0.83 M$_\odot$. Kepler-411 hosts at least four planets, the inner planet is a super-Earth with a radius of 1.88 R$_\oplus$ and an orbital period of 3.0051 days, whereas the two larger transiting planets are mini Neptunes with radii of 3.27 and 3.31 R$_\oplus$, and periods of 7.834435 and 58.0204 days, respectively. Their orbits are such that they transit the star at latitudes of -11$^{\circ}$, -21$^{\circ}$, and -49$^{\circ}$. Analysis of the transit light curves of the three planets resulted in the detection of a total of 198 spots. For each transit latitude, the rotation period of the star was estimated and the differential rotation pattern estimated independently. Then a solar like differential rotation profile was fit to the three rotation periods at the distinct latitudes, the result agreed extremely well with the previous ones, resulting in a differential shear of $0.0500\pm0.0006$ rd/d or a relative differential rotation of $8.4\pm0.1$\%.

Chemically Tagging the HR1614 Moving Group

description: We present abundances for a sample of F,G,K dwarfs of the HR1614 moving group based on high resolution, high S/N ratio spectra from AAT/UCLES. Our sample includes stars from Feltzing & Holmberg (2000, A&A, 357, 153), as well as from Eggen (1998, AJ, 115, 2453). Abundances were derived for Na, Mg, Al, Si, Ca, Mn, Fe, Ni, Zr, Ba, Ce, Nd, and Eu. The alpha, Fe, and Fe-peak element abundances show a bimodal distribution, with four stars having solar metallicities while the remaining 14 stars are metal rich [Fe/H] >= 0.25 dex. However the abundances of these two groups converge for the heavier n-capture elements. Based on their photometry and kinematics, three of the four deviating stars are likely non-members or binaries. Although one star cannot be excluded on these grounds, we do expect low-level contamination from field stars within the HR1614 moving group's range of magnitude, color and space velocities. Disregarding these four stars, the abundance scatter across the group members for all elements is low. We find that there is an 80% probability that the intrinsic scatter does not exceed the following values: Fe 0.01; Na 0.08; Mg 0.02; Al 0.06; Si 0.02; Ca 0.02; Mn 0.01; Ni 0.01; Zr 0.03; Ba 0.03; Ce 0.04; Nd 0.01 and Eu 0.02 dex. The homogeneity of the HR 1614 group in age and abundance suggests that it is the remnant of a dispersed star-forming event. Its kinematical coherence shows that such a dispersing system need not be significantly perturbed by external dynamical influences like galactic spiral structure or giant molecular clouds, at least over a period of 2 Gyr.
