    Reflections on Teaching Anthropologically and Fostering Belonging as Anti-Racist Allies in a ‘Widening Participation’ University: An Ecological Approach

    This article critically reflects on anti-racist and anthropological teaching practices in a widening participation university. It argues that to make meaningful change to entrenched racism and awarding gaps in higher education lecturers must take action and work towards embedding anti-racism into every level of the university structure. We propose using an ecological model with lecturers at its heart as a practical tool to support this work. Lecturers can begin by examining themselves and bring their vulnerabilities and openness to change to their different fields of connectivity – with students, with the curriculum, with academic structures, and with colleagues, across the institution. Such work helps challenge sedimented beliefs and practices and moves the institution toward becoming a more inclusive or pro-belonging university for students and staff alike

    Migratory Divorce: A Proposed Congressional Remedy

    It is the thesis of this paper that a review of the procession of cases in which the Supreme Court has unsuccessfully grappled with the problems posed by inter-state divorce, dating back to Cheever v. Wilson, decided in 1869, and continuing up to the present decision, make manifest the inadequacy of the judiciary as the agency for resolving these problems. It is this inadequacy of the judiciary\u27s solution which suggests that in definitive legislation may be found a more adequate instrumentality for the elimination of many of the existing uncertainties, conflicts, and difficulties in the administration of divorce laws

    Radiation Shielding for Nuclear Thermal Propulsion

    Design and analysis of radiation shielding for nuclear thermal propulsion has continued at Marshall Space Flight Center. A set of optimization tools are in development, and strategies for shielding optimization will be discussed. Considerations for the concurrent design of internal and external shielding are likely required for a mass optimal shield design. The task of reducing radiation dose to crew from a nuclear engine is considered to be less challenging than the task of thermal mitigation for cryogenic propellant, especially considering the likely implementation of additional crew shielding for protection from solar particles and cosmic rays. Further consideration is thus made for the thermal effects of radiation absorption in cryogenic propellant. Materials challenges and possible methods of manufacturing are also discussed

    Computational modeling of microRNA Biogenesis

    Over the past few years it has been observed, thanks in no small part to high-throughput methods, that a large proportion of the human genome is transcribed in a tissue- and time-specific manner. Most of the detected transcripts are non-coding RNAs and their functional consequences are not yet fully understood. Among the different classes of non-coding transcripts, microRNAs (miRNAs) are small RNAs that post-transcriptionally regulate gene expression. Despite great progress in understanding the biological role of miRNAs, our understanding of how miRNAs are regulated and processed is still developing. High-throughput sequencing data have provided a robust platform for transcriptome-level, as well as gene-promoter analyses. In silico predictive models help shed light on the transcriptional and post-transcriptional regulation of miRNAs, including their role in gene regulatory networks. Here we discuss the advances in computational methods that model different aspects of miRNA biogeneis, from transcriptional regulation to post-transcriptional processing. In particular, we show how the predicted miRNA promoters from PROmiRNA, a miRNA promoter prediction tool, can be used to identify the most probable regulatory factors for a miRNA in a specific tissue. As differential miRNA post-transcriptional processing also affects gene-regulatory networks, especially in diseases like cancer, we also describe a statistical model proposed in the literature to predict efficient miRNA processing from sequence features

    Phenomenological model for predicting the energy resolution of neutron-damaged coaxial HPGe detectors

    Full text link
    The peak energy resolution of germanium detectors deteriorates with increasing neutron fluence. This is due to hole capture at neutron-created defects in the crystal which prevents the full energy of the gamma-ray from being recorded by the detector. A phenomenological model of coaxial HPGe detectors is developed that relies on a single, dimensionless parameter that is related to the probability for immediate trapping of a mobile hole in the damaged crystal. As this trap parameter is independent of detector dimensions and type, the model is useful for predicting energy resolution as a function of neutron fluence.Comment: 7 pages, 7 figure

    Structural and electronic properties of Li intercalated graphene on SiC(0001)

    Full text link
    We investigate the structural and electronic properties of Li-intercalated monolayer graphene on SiC(0001) using combined angle-resolved photoemission spectroscopy and first-principles density functional theory. Li intercalates at room temperature both at the interface between the buffer layer and SiC and between the two carbon layers. The graphene is strongly nn-doped due to charge transfer from the Li atoms and two π\pi-bands are visible at the Kˉ\bar{K}-point. After heating the sample to 300^\circC, these π\pi-bands become sharp and have a distinctly different dispersion to that of Bernal-stacked bilayer graphene. We suggest that the Li atoms intercalate between the two carbon layers with an ordered structure, similar to that of bulk LiC6_6. An AA-stacking of these two layers becomes energetically favourable. The π\pi-bands around the Kˉ\bar{K}-point closely resemble the calculated band structure of a C6_6LiC6_6 system, where the intercalated Li atoms impose a super-potential on the graphene electronic structure that opens pseudo-gaps at the Dirac points of the two π\pi-cones.Comment: 9 pages, 7 figure
