description: SuperSpec is an on-chip filter-bank spectrometer designed for wideband moderate-resolution spectroscopy at millimeter wavelengths, employing TiN kinetic inductance detectors. SuperSpec technology will enable large-format spectroscopic integral field units suitable for high-redshift line intensity mapping and multi-object spectrographs. In previous results we have demonstrated noise performance in individual detectors suitable for photon noise limited ground-based observations at excellent mm-wave sites. In these proceedings we present the noise performance of a full $R\sim 275$ spectrometer measured using deployment-ready RF hardware and software. We report typical noise equivalent powers through the full device of $\sim 3 \times 10^{-16} \ \mathrm{W}/\sqrt{\mathrm{Hz}}$ at expected sky loadings, which are photon noise dominated. Based on these results, we plan to deploy a six-spectrometer demonstration instrument to the Large Millimeter Telescope in early 2020.

description: We predict the loss of superfluidity in a Bose-Einstein condensate in an axially symmetric harmonic trap alone during resonant collective oscillations via a classical dynamical transition. The forced resonant oscillation can be initiated by (a) a periodic modulation of the atomic scattering length with a frequency that equals twice the radial trapping frequency or multiples thereof, or by (b) a periodic modulation of the radial trapping potential with a frequency that equals the radial trapping frequency or multiples thereof. Suggestion for future experiment is made.

description: Changes in the functional state of mitochondria have profound effects on other cellular compartments. Genome-wide expression analysis of Arabidopsis rps10 mutants with an RNAi-silenced expression of mitoribosomal S10 protein has revealed extensive transcriptional reprogramming. A meta-analysis comparing expression datasets of 25 mitochondrial perturbations showed a high similarity of the aox1a:rpoTmp mutant, which is defective in the alternative oxidase (AOX1a) and dual-targeted mitochondrial and plastid RNA polymerase (RPOTmp), to rps10. Both rps10 and aox1a:rpoTmp showed a significantly decreased electron flux through both the cytochrome and the alternative respiratory pathways, and a markedly decreased the expression of nuclear-encoded components of the chloroplast transcription machinery. In line with this, a decreased level of plastid transcripts was observed in rps10 and aox1a:rpoTmp, which was reflected in a reduced rate of chloroplast transcription. Chemical treatment of wild-type seedlings with respiratory inhibitors showed that only simultaneous and direct inhibition of complex IV and AOX activity decreased the level of plastid transcripts. Taken together, both chemical and genetic studies show that the limitation of the activity of two mitochondrial terminal oxidases, complex IV and AOX, negatively impacts chloroplast transcription. Salicylic acid and oxygen are discussed as putative mediators of the signalling pathway between mitochondria, nucleus and chloroplasts.This article is part of the theme issue ‘Retrograde signalling from endosymbiotic organelles’.

description: Muslim Rohingyas living in the Rakhine State of Myanmar live as stateless persons, as the government of Myanmar continues to refuse their right to citizenship. They are deemed foreigners, ethnically Bengali, and therefore unwelcomed in Myanmar. Their dehumanization has led to gross human rights atrocities including ethnic cleansing, torture and starvation. What is the moral and legal responsibility of the state and the international community to protect their human rights and uphold international law? Also, how has trauma and isolation affected them and what are the methods of healing and moral repair needed? Exploring these questions is vital to examining the social consequences on Muslim Rohingya communities in specific and on marginalized ethnic populations in general. Using interpretive ethnography as the primary research method, this paper will task itself with further exploring these complex questions.

description: It is discussed the limitations of the widely used markovian approximation applied to model the turbulent refractive index in lightwave propagation. It is well-known the index is a passive scalar field. Thus, the actual knowledge about these quantities is used to propose an alternative stochastic process to the markovian approximation: the fractional Brownian motion. This generalizes the former introducing memory; that is, there is correlation along the propagation path.

description: We propose a simple situation in which the magnetic Aharonov-Bohm potential influences the values of the deficiency indices of the initial Schrödinger operator, so determining whether the particle interacts with the solenoid or not. Even with the particle excluded from the magnetic field, the number of self-adjoint extensions of the initial Hamiltonian depends on the magnetic flux. This is a new point of view of the Aharonov-Bohm effect.

description: This study investigated the consumer perceptions about special butchers, also known as “gourmet meat shops”. The objective was to list the factors that contribute to a differentiated perception of gourmet meat shops and whether these factors are related to coordination of quality in clusters of differentiated quality meat. Methodological procedures of qualitative research were adopted. Three case studies were described in gourmet meat shops located in São Paulo, Goiânia and Florianópolis. Semi-structured interviews were conducted with owners and consumers at different times of purchase, during weekdays and weekends. The study concluded that the provision of differentiated services and the adoption of strict coordination mechanisms ensure a positive consumer perceptions about the quality of meat purchased in gourmet meat shops.

description: The objective of this paper is to present the results of a bibliographic effort oriented hypothetical and conceptual development of a maturity model for certified processes in agribusiness systems in view of the of the supply chain management. The variables that constitute this model were specified from the relevant attributes to the accreditation process developed by coffee SAG institutions. Such attributes are distributed at different levels of maturity. The model parameters were selected because they are the essential factors contained in the main certification standards used in Brazilian coffee and are aligned with the requirements of BPO approach (Business Process Orientation). The model allows to analyze the level of the relationship between process maturity of certified firms and its impact on organizational performance.

description: First principles linear combinations of Gaussian type orbitals-fitting function (LCGTO-FF) electronic structure calculations are used to study thickness dependencies in the surface energies and work functions of ultra-thin (111) films of fcc delta-Pu, up to five layers thick. The calculations are carried out at both scalar- and fully-relativistic (with and without spin-orbit coupling) levels of approximation. The surface energy is shown to be rapidly convergent, while the work function exhibits a strong quantum size effect for all thicknesses considered. The surface energy and work function of the semi-infinite solid are predicted to be 1.12 J/m^2 and 2.85(+ or -0.20) eV, respectively, for the fully-relativistic case. These results are in substantial disagreement with results from previous electronic structure calculations. The present predictions are in fair agreement with the most recent experimental data for polycrystalline delta-Pu, namely 0.91 J/m^2 and 3.1-3.3 eV, for the surface energy and work function, respectively.

description: Finite temperature Euclidean SU(2) lattice gauge fields close to the deconfinement phase transition are subjected to cooling. We find relatively stable or absolutely stable configurations with an action below the one-instanton action $S_{inst}=2π^2$ both in the deconfinement and the confinement phases. In this paper we attempt an interpretation of these lowest action configurations. Their action is purely magnetic and amounts to $S/S_{inst} \approx N_t/N_s$, where $N_t$ ($N_s$) is the timelike (spacelike) lattice size, while the topological charge vanishes. In the confined phase part of the corresponding lattice configurations turns out to be absolutely stable with respect to the cooling process in which case Abelian projection reveals a homogeneous, purely Abelian magnetic field closed over the "boundary" in one of the spatial directions. Referring to the dyonic structure established for the confinement phase near $T_c$ and based on the observation made for this phase that such events below the instanton action $S_{inst}$ emerge from dyon-antidyon annihilation, the question of stability (metastability) is discussed for both phases. The hypothetically different dyonic structure of the deconfinement phase, inaccessible by cooling, could explain the metastability.

title: Talk and learning ESL-examing the effectiveness of teacher talk in terms of fostering the learning of esl students in a Portuguese classroom
Creators: name: Simas, Luis Filipe
Publisher: name: The Open University
Year: 2010

description: This dissertation describes classroom-based research on talk and learning. The educational problem I addressed is underachievement. My research addressed a group of thirteen to fourteen year-old ESL students in Portuguese classrooms, with a view to foster their speaking skills and turn them into successes, through the use of scaffolding techniques. The theoretical framework for my research was largely informed by Vygotsky's theory of socio-cognitive development, complemented by contributions from the Neo-Vygotskian school of thought. But, given the specifics of its context, other research traditions also receive attention in my literature review. Among these are research on the importance of context and ideology for my study, and research on the grammar of spoken English. The research design adopted for both the pilot and the main research study was a quasiexperimental 'pre and post' approach, intended to test the outcomes achieved by the use of specific scaffolding strategies. The analysis looked at scaffolding already being used by the teachers I worked with and identified weaknesses and possible ways of scaffolding the learners, with references to the literature reviewed. I then identified and discussed these additional possibilities with the teachers and recorded and analysed their subsequent work with the learners. A tentative conclusion is that it is possible to foster the speaking skills of underachievers in the contexts under analysis, through a more sensitive deployment of scaffolding strategies by the teacher. While more research is needed in this field, it is hoped that my study will make a valid contribution to the teaching of English, as a foreign language in non-English speaking countries.
title: An investigation into the role of chromatin modifying elements on the production of recombinant antibodies from CHO Cells
Creators: name: Saunders, Fay Louise
Publisher: name: The Open University
Year: 2011

description: Stable cell line generation requires the gene of interest to become stably integrated into the host cells genome. The generation of stable cell lines by random integration produces large variation in clonal expression and stability that is due, in part, to the nature of the chromatin it has integrated into. Elements have been identified that can modify the chromatin structure and have been shown to protect transgcne expression from the effects of the neighbouring chromatin environment. The aim of the study was to investigate whether the identified chromatin structure modifying elements (UCOE, MAR, STAR and HS4) could increase the level and stability of antibody expression in stable cell lines in the mammalian expression systems used at UCB. A series of expression constructs were generated to assess the effect of the chromatin structure modifying elements on antibody expression in stable cell lines. Initially seven different vectors for each clement that possessed different combinations of the individual elements were assessed as pooled and clonal stable cell populations which indicated that the elements increased antibody expression by varying amounts and optimal vector configurations were different for the elements. The optimised vectors were subsequently used in a comparative side-by-side study with expression levels from pooled and stable cell lines being analysed. A subset of clones harbouring each of the five test constructs (Ab535 control, 1.5kb A2UCOE, MAR X_S29, STAR 7 and cHS4 tandem) derived from the pooled stable cell lines were genetically characterised to determine copy number and clonal diversity. Clones were cultured long-term in the absence of selection pressure which resulted in a decrease in expression being observed in all of the clones. The decline in antibody expression was accompanied by a decrease in mRNA levels which was not caused by a loss of either HC or LC gene copies from the genome. Analysis of DNA methylation patterns across the hCMV-MIE promoter regions demonstrated that this epigenetic regulatory mechanism was involved in the silencing of a number of clones which exhibited a decreasein productivity.

description: The magnitude-limited catalog of the Southern Sky Redshift Survey (SSRS2), is used to characterize the properties of galaxies hosting Active Galactic Nuclei. Using emission-line ratios, we identify a total of 162 (3%) Seyfert galaxies out of the parent sample with 5399 galaxies. The sample contains 121 Seyfert 2 galaxies and 41 Seyfert 1. The SSRS2 Seyfert galaxies are predominantly in spirals of types Sb and earlier, or in galaxies with perturbed appearance as the result of strong interactions or mergers. Seyfert galaxies in this sample are twice as common in barred hosts than the non-Seyferts. By assigning galaxies to groups using a percolation algorithm we find that the Seyfert galaxies in the SSRS2 are more likely to be found in binary systems, when compared to galaxies in the SSRS2 parent sample. However, there is no statistically significant difference between the Seyfert and SSRS2 parent sample when systems with more than 2 galaxies are considered. The analysis of the present sample suggests that there is a stronger correlation between the presence of the AGN phenomenon with internal properties of galaxies (morphology, presence of bar, luminosity) than with environmental effects (local galaxy density, group velocity dispersion, nearest neighbor distance).

description: Recently Segev et al. (Phys. Rev. E 64,2001, Phys.Rev.Let. 88, 2002) made long-term observations of spontaneous activity of in-vitro cortical networks, which differ from predictions of current models in many features. In this paper we generalize the EI cortical model introduced in a previous paper (S.Scarpetta et al. Neural Comput. 14, 2002), including intrinsic white noise and analyzing effects of noise on the spontaneous activity of the nonlinear system, in order to account for the experimental results of Segev et al.. Analytically we can distinguish different regimes of activity, depending from the model parameters. Using analytical results as a guide line, we perform simulations of the nonlinear stochastic model in two different regimes, B and C. The Power Spectrum Density (PSD) of the activity and the Inter-Event-Interval (IEI) distributions are computed, and compared with experimental results. In regime B the network shows stochastic resonance phenomena and noise induces aperiodic collective synchronous oscillations that mimic experimental observations at 0.5 mM Ca concentration. In regime C the model shows spontaneous synchronous periodic activity that mimic activity observed at 1 mM Ca concentration and the PSD shows two peaks at the 1st and 2nd harmonics in agreement with experiments at 1 mM Ca. Moreover (due to intrinsic noise and nonlinear activation function effects) the PSD shows a broad band peak at low frequency. This feature, observed experimentally, does not find explanation in the previous models. Besides we identify parametric changes (namely increase of noise or decreasing of excitatory connections) that reproduces the fading of periodicity found experimentally at long times, and we identify a way to discriminate between those two possible effects measuring experimentally the low frequency PSD.

title: Social presence in online multimodal communication: A framework to analyse online interactions between language learners
Creators: name: Satar, Hatice Müge
Publisher: name: The Open University
Year: 2011

description: New technologies permeate every aspect of life, not least human communication. Collaboration and social interaction have become buzz words in online communication and education mediated by Web 2.0 technologies and inspired by socio-constructivist theories of learning. Social presence theory explores this mediation through which individuals project themselves socially and emotionally into the community (Rourke, Anderson, Garrison, & Archer, 1999). Understanding the experience of social presence is crucial for its strategic use in online learning, while the pivotal role of communication makes social presence an indispensable component of language teaching. Although social presence theory has evolved from a media richness view as a quality of the media (Short, Williams, & Christie, 1976) to a relational view as a quality of relational aspects of communication (Kehrwald, 2008), the multimodal nature of new technologies has not previously been explored. Social presence research has also largely ignored the role of language (verbal or nonverbal, native or foreign) on the mediation process. This exploratory case study investigates social presence in dyadic online foreign language interaction via desktop videoconferencing (DVC) between trainee language teachers. Multiple data sources (DVC recordings, interviews, questionnaires) are qualitatively analysed, drawing on principles of thematic analysis, interactional linguistics and social semiotics. The findings highlight the need for workable methods, tools and theories to research and analyse multimodal online communication. Social presence theory is revised to accommodate multi modal foreign-language interactions, and to incorporate potential differences between the ways individuals intend to project themselves and the ways this projection might be perceived by others in the community. An original approach to analysing and classifying language-learner interactions is demonstrated. Pedagogical implications stress the skills required to support rewarding educational experiences for both learners and teachers. Despite the specific features of the case study; the findings--can be extrapolated to virtually all areas of online communication.

description: Synthesis of large-scale, uniform, easily transferable, and highly crystalline monolayer (1L) molybdenum disulfide (MoS2) on different substrates is a challenge and could decide its suitability for opto-electronic device applications. Herein, we report a facile NaCl-assisted Chemical Vapor Deposition (CVD) synthesis of high-quality MoS2 on amorphous, crystalline and layered substrates. Optical microscopy and Raman spectroscopy show that sapphire and SiO2/Si are suitable substrates for large 1L-MoS2 flakes growth, while mica is excellent for large-area continuous films. Comparatively lesser full-width-at-half-maximum (FWHM) of predominant A exciton peak (which is associated with direct band gap at K point) in photoluminescence spectra of 1L-MoS2 on sapphire suggests its high crystalline quality. However, 1L-MoS2 on other substrates, especially on quartz and bare Si show poor crystalline quality. The study depicts that the NaCl assists in the formation of seeding promoter such as water-soluble layer of Na2S and/or Na2SO4 on the substrate that helps in 2D planar nucleation of MoS2. The formation of such intermediate seeding layers also helps in layer transfer owing to its easy water solubility. The study could be utilized for large-scale synthesis of 1L-MoS2 on different substrates for high-performance optoelectronic devices.

description: In this article we present preliminary results on the upper limits to the mass of a companion for 8 apparently single subdwarf B stars, derived from high-precision radial velocity measurements obtained from Harps-N spectra. These limits, corresponding to a few Jupiter masses, show that these stars do not have close companions and keep open the unresolved question of the mechanism that caused the almost complete loss of the envelope for the giant precursors of these stars. For 4 stars with a larger data coverage, it was also possible to set upper limits to the mass of a more massive companion in a wider orbit.

description: From velocity-gated small-angle correlation functions the emission chronology can be deduced for non-identical particles, if the emission is independent. This is not the case for non-identical particles that originate from two-body decay of fragments. Experimental results may contain contributions from both independent emission and two-body decay, so care is needed in interpreting the velocity-gated correlation functions. It is shown that in some special cases, it is still possible to deduce the emission chronology, even if there is a contribution from two-body decay.

description: Companion galaxy environment for a subset of 78 bright and nearby barred galaxies from the Shapley Ames Catalog is presented. Among spiral barred galaxies there are Seyfert galaxies, galaxies with circumnuclear structures, galaxies not associated with any large scale galaxy cloud structure, galaxies with peculiar disk morphology (crooked arms) and galaxies with normal disk morphology; the list includes all Hubble types. The companion galaxy list includes number of companion galaxies within 20 diameters (D25), their Hubble type and projected separation distance. Additionally, companion environment was searched for four known active spiral galaxies, three of them are Seyfert galaxies, namely, NGC 1068, NGC 1097, NGC 5548 and one is a starburst galaxy, M82. Among the results obtained it is noted that the only spiral barred galaxy classified as Sy 1 in our list has no companions within a projected distance of 20 diameters; 6 out of 10 Sy 2 bar galaxies have no companions within 10 diamters, 6 out of 10 Sy 2 galaxies have one or more companions at projected separation distances between 10 and 20 diameters; 6 out of 12 galaxies with circumnuclear structures have 2 or more companions within 20 diameters

title: Automatic Multilevel Feature Abstraction in Adaptable Machine Vision Systems

description: Vision is a complex task which can be accomplished with apparent ease by biological systems, but for which the design of artificial systems is difficult. Although machine vision systems can be successfully designed for a specific task, under certain conditions, they are likely to fail if circumstances change. This was the motivation for the research into ways in which systems can be self-designing and adaptable to new visual tasks. The research was conducted in three vital areas of concern for machine vision systems. The first area is finding a suitable architecture for forming an appropriate representation for the current task. The research investigated the application of Hypernetworks theory to building a multilevel, generally-applicable representation, through repeated application of a fundamental 'self-similarity' principle, that parts of objects assembled under a particular relation at one level, form whole objects at the next. Results show that this is potentially a powerful approach for autonomously generating an adaptable system-architecture suitable for multiple visual tasks. The second area is the autonomous extraction of suitable low-level features, which the research investigated through random generation of minimally-constrained pixel-configurations and algorithmic generation of homogeneous and heterogeneous polygons. The results suggest that, despite the simplicity of the features making them vulnerable to image transformations, these are promising approaches worth developing further. The third area is automatic feature selection. The research explored management of 'dimensionality' and of 'combinatorial explosion', as well as how to locate relevant features at multiple representation levels, in the context of 'emergence' of structure. Results indicate that this approach can find useful 'intermediate-level' constructs through analysis of the connectivity of the simplices representing objects at higher levels. The research concludes that the proposed novel approaches to tackling the above issues, in particular the application of hypernetworks to the formation of multilevel representations and the resulting emergence of higher-level structure, is fruitful.
CHANDRA Observations of the X-ray Halo around the Crab Nebula

description: Two Chandra observations have been used to search for thermal X-ray emission from within and around the Crab Nebula. Dead-time was minimized by excluding the brightest part of the Nebula from the field of view. A dust-scattered halo comprising 5% of the strength of the Crab is clearly detected with surface brightness measured out to a radial distance of 18 arcminutes. Coverage is 100% at 4 arcminutes, 50% at 12 arcminutes, and 25% at 18 arcminutes. The observed halo is compared with predictions based on 3 different interstellar grain models and one can be adjusted to fit the observation. This dust halo and mirror scattering form a high background region which has been searched for emission from shock-heated material in an outer shell. We find no evidence for such emission. We can set upper limits a factor of 10-1000 less than the surface brightness observed from outer shells around similar remnants. The upper limit for X-ray luminosity of an outer shell is about 10e34 erg/s. Although it is possible to reconcile our observation with an 8-13 solar mass progenitor, we argue that this is unlikely.

description: We present an investigation of synthetic spectroscopic indices that can plausibly help in identifying the presence of multiple stellar populations in globular clusters. The study is based on a new grid of stellar model atmospheres and high-resolution (R=500,000) synthetic spectra, that consider chemical partitions that have been singled out in Galactic globular clusters. The database is composed of 3472 model atmospheres and theoretical spectra calculated with the collection of Fortran codes DFSYNTHE, ATLAS9 and SYNTHE, developed by Robert L. Kurucz. They cover a range of effective temperature from 4300 to 7000 K, surface gravity from 2.0 to 5.0 dex and four different chemical compositions. A set of 19 spectroscopic indices were calculated from a degraded version (R=2500) of the theoretical spectra dataset. The set includes five indices previously used in the context of globular clusters analyses and 14 indices that we have newly defined by maximizing the capability of differentiating the chemical compositions. We explored the effects of atmospheric parameters on the index values and identified the optimal spectral diagnostics that allow to trace the signatures of objects of different stellar populations, located in the main sequence, the red giant branch and the horizontal branch. We found a suitable set of indices, that mostly involve molecular bands (in particular NH, but also CH and CN), that are very promising for spectroscopically identifying multiple stellar populations in globular clusters.

Food Consumption/Nutrition/Food Safety

description: S cientific research increasingly confirms that a healthful diet reduces the risk of developing chronic diseases. Many groups, including the food industry, voluntary organizations (like the American Heart Association), and Federal and local government agencies, either independently or cooperatively, have stepped in to accelerate the trend toward healthful eating by promoting eating patterns that conform to Federal recommendations. These efforts have focused on providing nutrition information and education to persuade and guide Americans to consume more healthful diets, and/ or directly altering the nutrient content of foods or meals. Many Americans seem to have heard the message. High interest in nutrition during the 1990's prompted the food industry to step in with products and information to help Americans choose healthful foods. Evidence suggests that some Americans are changing their diets and moving closer to recommendations by nutritionists and other health professionals. However, changes vary considerably, both for individuals and food groups. For example, USDA food consumption surveys show that fat intake as a percentage of total calories has declined in the last decade-a move in the right direction. The same surveys, however, show that people are not increasing their consumption of fruits and vegetables as recommended, and that the number of obese Americans is rising.
High-$p_{T}$ electron distributions in d+Au and p+p collisions at RHIC

description: We present preliminary measurements of electron and positron spectra in d+Au and p+p collisions at $\sqrt{s_{NN}}=200$ GeV for $1.5 < p_{T} < 7.0$ GeV/c. These measurements were carried out using the STAR Time Projection Chamber (TPC) and the Barrel Electromagnetic calorimeter (EMC). Overall hadron rejection factors in the range of $10^{5}$ have been achieved. In this work we describe the measurement technique used to discriminate electrons from hadrons and compare the results for single electron spectra with Pythia based pQCD calculations for electrons from heavy-quark semi-leptonic decays.

description: The bending rigidity $k_c$ of bilayer vesicles self-assembled from amphiphilic diblock copolymers has been measured using single and dual-micropipet techniques. These copolymers are nearly a factor of 5 greater in hydrophobic membrane thickness $d$ than their lipid counterparts, and an order of magnitude larger in molecular weight $\bar{M}_n$. The macromolecular structure of these amphiphiles lends insight into and extends relationships for traditional surfactant behavior. We find the scaling of $k_c$ with thickness to be nearly quadratic, in agreement with existing theories for bilayer membranes. The results here are key to understanding and designing soft interfaces such as biomembrane mimetics.
