    (A) The atomic model (7X7M) composed of 60 monomers arranged in icosahedral symmetry is superimposed into the cryo-EM map. (B) The ribbon diagram of LS is viewed from the 5-fold axis. (C) The atomic model of the monomer based on the cryo-EM map (cyan) is superimposed on the x-ray crystal structure (tan, 1HQK). The RMSD of both structures is 0.174 Å for the 154 Cα atoms. (D) The pentamer of LS based on the cryo-EM map (cyan) coincides with that of the x-ray crystal structure of Aquifex aeolicus LS (tan, 1HQK). (E) Representative secondary structural elements of the LS complex are shown within the cryo-EM map.</p

    Sex differences in quadrupedal walking gaits of Uner Tan syndrome cases, healthy humans and nonhuman primates

    No full text
    PubMedID: 28058999Background: Uner Tan syndrome (UTS) cases with habitual quadrupedal locomotion (QL), impaired intelligence, and dysarthric or no speech predominantly use lateral sequence (LS) gait like nonprimates rather than the predominantly diagonal sequence (DS) gait of nonhuman primates. However, these studies neglected possible sex-related differences in these gait types. Objectives: (1) To assess the possible sex-related gait types in UTS cases, healthy infants and adults with requested QL, and the nonhuman primates. (2) To test the hypothesis that sex differences may exist in quadrupedal walking gaits in UTS cases, healthy humans, and nonhuman primates. Methods: The UTS cases were filmed, the other study groups were taken from public open ‘youtube’ videos, which were used to assess the walking gait types as DS and LS. The right and left hind-limb phase values were calculated separately for males and females to allow a possible sex difference in walking gaits to be determined. Results: Females predominantly used DS gait, contrary to males with predominantly LS gait. Conclusions: Consistent with the working hypothesis, the results suggested a biological sex-related trend in preferred walking gaits exists in all of the human and nonhuman primates using QL. © 2017 Informa UK Limited, trading as Taylor & Francis Group

    Author Attributions in Medieval Text Collections: An Exploration

    No full text
    This article examines the role and function of author attributions in multi-text manuscripts containing Dutch, English, French or German short verse narratives. The findings represent one strand of the investigations undertaken by the cross-European project ‘The Dynamics of the Medieval Manuscript’, which analysed the dissemination of short verse narratives and the principles of organisation underlying the compilation of text collections. Whilst short verse narratives are more commonly disseminated anonymously, there are manuscripts in which authorship is repeatedly attributed to a text or corpus. Through six case studies, this article explores medieval concepts of authorship and how they relate to constructions of authority, whether regarding an empirical figure or a literary construction. In addition, it looks at how authorship plays a role in manuscript compilation, and at the effects of attributions (by author and/or compiler) on reception. The case studies include manuscripts from the thirteenth to fifteenth centuries, produced in a range of social and cultural contexts, and featuring some of the most important European authors of short verse narratives: Rutebeuf, Baudouin de Condé, Der Striker, Konrad von Würzberg, Willem of Hildegaersberch, and Geoffrey Chaucer. The preliminary findings contribute to our understanding of author attributions in text collections from across northern Europe and point towards future lines of enquiry into the role of authorship in medieval textual dissemination

    Batch Bayesian Learning of Large-Scale LS-SVMs Based on Low-rank Tensor Networks

    No full text
    Least Squares Support Vector Machines (LS-SVMs) are state-of-the-art learning algorithms that have been widely used for pattern recognition. The solution for an LS-SVM is found by solving a system of linear equations, which involves the computational complexity of O(N^3). When datasets get larger, solving LS-SVM problems with standard methods becomes burdensome or even unfeasible. The Tensor Train (TT) decomposition provides an approach to representing data in highly compressed formats without loss of accuracy. By converting vectors and matrices in the TT format, the storage and computational requirements can be greatly reduced. In this thesis, we develop a Bayesian learning method in the TT format to solve large-scale LS-SVM problems, which involves the computation of a matrix inverse. This method allows us to include the information we know about the model parameters in the prior distribution. As a result, we are able to obtain a probability distribution of the parameters, which enables us to construct confidence levels of the predictions. In the numerical experiment, we show that the developed method performs competitively with the current methods.Mechanical Engineering | Systems and Contro

    Additive Manufacturing: Polymers Applicable for Laser Sintering (LS)

    No full text
    AbstractAdditive Manufacturing (AM) is close to become a production technique changing the way of part fabrication in future. Enhanced complexity and personalized features are aimed. The expectations in AM for the future are enormous and betimes it is considered as kind of the next industrial revolution. Laser Sintering (LS) of polymer powders is one component of the AM production techniques. However materials successfully applicable to Laser Sintering (LS) are very limited today. The presentation picks up this topic and gives a short introduction on the material available today. Important factors of polymer powders, their significance for effective LS processing and analytical approaches to access those values are presented in the main part. Concurrently the exceptional position of polyamide 12 powders is this connection is outlined

    Electrical evaluation of laser annealed junctions by Hall measurements

    No full text
    Hall measurements performed on laser annealed ultrashallow ion implanted p-type layers on n-type substrates over a wide temperature range showed expected p-type characteristics at low temperature but unexpected n-type behaviour at higher temperature. Samples annealed with lower laser energy fluences displayed the unexpected n-type characteristics over a wider temperature range compared to those annealed at higher energy fluences. These results can be explained by the increased contribution of the n-type substrate to the Hall readings, made possible by a more leaky junction, when the implant damage is inadequately removed. Thus, Hall measurements can be proposed as a quick evaluation tool of the integrity of laser annealed junctions without the need of device fabrication or high-resolution transmission electron microscopy.
