Transcriptional profiling of the M. complexus in naked neck chickens suggest a direct pleiotropic effect of GDF7 on feathering and reduced hatchability
No full textAbstract Background The locus for naked neck (Na) in chickens reduces feather coverage and leads to increased heat dissipation from the body surface resulting in better adaptability to hot conditions. However, the Na gene is linked to significantly lower hatchability due to an increased late embryonic mortality. It has been argued that the causative gene GDF7 may have a direct pleiotropic effect on hatchability via its effect on muscle development. Thus, the study presented here analyses the transcriptome of the hatching muscle (M. complexus) and shows how GDF7 impacts development leading to reduced hatching rates in Na chickens. Results Using 12 chicken embryos (6 x wildtype (Wt) and 6 x Na) RNA was extracted from the M. complexus of each embryo and sequenced. The resulting differential expression analyses led to the discovery of 461 differentially expressed (DE) genes in the M. complexus of the experimental group. Among those, 77 genes were of uncertain function (LOC symbols), with 31 were classified as uncharacterised. The regulation of a number of pathways involved in normal embryonic development, were found to be negatively influenced by the Na genotype. Further pathways involved in cell-cell adhesion, cell signalling pathways, and amino acid (AA) metabolism/transport were also observed. GDF7 (alias BMP12), whose localised overexpression in the neck skin causes the Na/Na phenotype, was significantly overexpressed in the M. complexus of Na/Na embryos, and shows a significant increase in the number of binding sites for the transcription factor PITX2 was also observed. Conclusion In Na chickens, GDF7 is under the control of a mutated cis-regulatory element, whose actions are known to suppress the development and distribution of feathers through the sensitizing action of retinoic acid. In this study, a number of DE genes with over 10 retinoic acid response elements (RAREs) in close proximity were observed, indicating changes to the retinol metabolism. With the understanding that the Na/Na mutation leads to increased retinoic acid activity, this indicates a high likelihood of GDF7 excerpting a direct pleiotropic effect, not just in the observed reduction in feather patterning, but also impacting the development of the M.complexus, and consequently leading to the reduced hatchability observed in birds with the Na/Na genotype. Furthermore, the enrichment of PITX2 binding sites in proximity to DE genes in the M. complexus, also indicates that muscle development is still ongoing in Na embryos. This suggests that the M. complexus is not yet fully developed, further increasing the potential for late embryonic mortality in Na chicks at hatching.Open-Access-Publikationsfonds 202

Enhancement of chiral edge currents in (+1)-dimensional atomic Mott-band hybrid insulators
No full textWe consider the effect of a local interatomic repulsion on synthetic
heterostructures where a discrete synthetic dimension is created by Raman
processes on top of -symmetric two-dimensional lattice systems. At a
filling of one fermion per site, increasing the interaction strength, the
system is driven towards a Mott state which is adiabatically connected to a
band insulator. The chiral currents associated with the synthetic magnetic
field increase all the way to the Mott transition, where they reach the maximum
value, and they remain finite in the whole insulating state. The transition
towards the Mott-band insulator is associated with the opening of a gap within
the low-energy quasiparticle peak, while a mean-field picture is recovered deep
in the insulating state.Comment: 27 Pages, 10 Figure
Exotic Quantum Spin Models in Spin-Orbit-Coupled Mott Insulators
No full textWe study cold atoms in an optical lattice with synthetic spin-orbit coupling in the Mott-insulator regime. We calculate the parameters of the corresponding tight-binding model using Peierls substitution and “localized Wannier states method” and derive the low-energy spin Hamiltonian for bosons and fermions. The spin Hamiltonian is a combination of Heisenberg model, quantum compass model and Dzyaloshinskii-Moriya interactions and it has a rich classical phase diagram with collinear, spiral and vortex phases. We discuss the state of the art of experiments to realize and detect magnetic orderings in strongly correlated optical lattices
Nanoscale self-organization and metastable non-thermal metallicity in Mott insulators
No full textMott transitions in real materials are first order and almost always associated with lattice distortions, both features promoting the emergence of nanotextured phases. This nanoscale self-organization creates spatially inhomogeneous regions, which can host and protect tran- sient non-thermal electronic and lattice states triggered by light excitation. Here, we combine time-resolved X-ray microscopy with a Landau-Ginzburg functional approach for calculating the strain and electronic real-space configurations. We investigate V2O3, the archetypal Mott insulator in which nanoscale self-organization already exists in the low-temperature monoclinic phase and strongly affects the transition towards the high-temperature corundum metallic phase. Our joint experimental-theoretical approach uncovers a remarkable out-of- equilibrium phenomenon: the photo-induced stabilisation of the long sought monoclinic metal phase, which is absent at equilibrium and in homogeneous materials, but emerges as a metastable state solely when light excitation is combined with the underlying nanotexture of the monoclinic lattice
Constructing the Cyberterrorist: Critical Reflections on the UK Case
No full textThis book maps and analyses the official British construction of the threat of cyberterrorism. By using interpretive discourse analysis, this book identifies ‘strands’ from a corpus of policy documents, statements and speeches from UK ministers, MPs and peers, between 12 May 2010 and 24 June 2016. The book examines how the threat of cyberterrorism was constructed in the UK, and what this securitisation has made possible. The author makes novel contributions to the Copenhagen School’s ‘securitisation theory’ framework by outlining a ‘tiered’ rather than monolithic audience system; refining the ‘temporal’ and ‘spatial’ conditioning of a securitisation with reference to the distinctive characteristics of cyberterrorism; and, lastly, by detailing the way in which popular fiction can be ascribed agency to ‘fill in’ an absence of ‘cyberterrorism’ case studies. He also argues that the UK government’s classification of cyberterrorism as a ‘Tier One’ threat created a central strand upon which a discursive securitisation was established
O auge de Nellie Bly: uma jornalista estadunidense no final do século XIX
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Jornalismo, Florianópolis, 2013.Esta pesquisa apresenta a análise de 11 reportagens escritas pela jornalista Nellie Bly e publicadas no jornal The New York World entre 1887 e 1889, com o objetivo de recuperar o trabalho desenvolvido por ela e avaliar as possíveis contribuições dessa mulher para a história do jornalismo. A partir das abordagens metodológicas da chamada Nova História, buscou-se contextualizar a análise em relação ao período histórico em que a jornalista se inseria. Os autores Michael Schudson, Frank Luther Mott e George Juergens ofereceram o suporte para a contextualização da história da imprensa nos Estados Unidos. Este trabalho pretende oferecer contribuições para o debate atual acerca de importantes questões para o jornalismo, nomeadamente, o método de apuração e a conceituação de jornalismo investigativo. Abstract : This research presents the analysis of 11 articles written by the journalist Nellie Bly and published in the New York World between 1887 and 1889, aiming at reviving the work she developed and at evaluating her possible contributions to the history of journalism. Based on methodological approaches provided by the so-called New History, the effort was to contextualize the analysis in relation to the historical period she belonged to. The authors Michael Schudson, Frank Luther Mott and George Juergens provided the basic grounding to rebuild the journalism history in the United States. This work intends to offer contributions to the current debate concerning important issues in journalism, namely, the newsgathering methods and conceptualization of investigative journalism
