Cross correlations of Frank sequences and Chu Sequences.
No full textSets of Frank sequences and Chu sequences are two classes of polyphase sequence with ideal periodic autocorrelation functions, which at the same time have optimum crosscorrelation functions. The authors consider the crosscorrelations of sets of combined Frank/Chu sequences, which contain a larger number of sequences than either of the two constituent sets. It is shown analytically that the crosscorrelations are similar to those of the original sets with one exception, while the autocorrelations remain perfectly impulsiv
Anomalies and locality in field theories and M-theory
No full textWe review some basic notions on anomalies in field theories and superstring theories, with particular emphasis on the concept of locality. The aim is to prepare the ground for a discussion on anomalies in theories with branes. In this light we review the problem of chiral anomaly cancellation in M-theory with a 5-brane
On the Low-Rank Approximation of Data on the Unit Sphere
No full textIn various applications, data in multidimensional space are normalized to unit length. This paper considers the problem of best fitting given points on the m-dimensional unit sphere Sm-1 by k-dimensional great circles with k much less than m. The task is cast as an algebraically constrained low-rank matrix approximation problem. Using the fidelity of the low-rank approximation to the original data as the cost function, this paper offers an analytic expression of the projected gradient which, on one hand, furnishes the first order optimality condition and, on the other hand, can be used as a numerical means for solving this problem

PCB 118 induces ultrastructural alterations in the rat liver
No full textPolychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that bioaccumulate in the food chain and thus pose a health risk to humans and other animals. In this study, PCB 118 was added to the diets of Sprague Dawley rats for 13 weeks in concentrations of 2, 20, 200, 2000 p.p.b. to the females and 10, 100, 1000 and 10 000 p.p.b, to the males. The chemical was dissolved in corn oil; animals that served as the control received corn oil in the diets devoid of PCB. Use of transmission electron microscopy and stereology revealed significant (P < 0.05) elevation in the mean volume fraction of smooth reticulum profiles (20 p.p.b.), peroxisomes (200, 2600 p.p.b.) and lipid droplets (2000 p.p.b.) in the females. Hepatocytes from the males exhibited a significant increase in the mean volume fraction of lipid droplets at 10 000 p.p.b. (P < 0.05). Interactions between large quantity of estrogen and the PCB probably would account for more profound alterations in the liver of female Sprague-Dawley rats than in the males.

STUDIO : Surveillance épidémiologique des prothèses orthopédiques dans les CHU de l'Ouest - cohorte à partir des entrepôts de données cliniques eHOP®
No full textNational audienceLa surveillance organisée spécifique des dispositifs médicaux implantables (DMI) est primordiale face aux enjeux de santé publique (complications, perte qualité vie et surcoûts pour la société), mais reste complexe. Les arthroplasties hanche, genou épaule (PTO) sont en hausse continue au vieillissement populations l'augmentation demandes, avec conditions pose (âge, comorbidités) plus à risque complications. Notre étude évaluait faisabilité d'une e-cohorte patients PTO, partir données cliniques du réseau d'entrepôts eHOP® (CDC). incluait les première PTO opérés entre 2010 2019 deux sources disponibles dans un EDS (CDC Rennes Tours): PMSI (22 actes CCAM) pharmacie (1523 codes LPP Assurance maladie). Le programme d'extraction automatique DMI a été développé par le CHU pilote: (i) identification séjours ou CCAM, (ii) sélection LPP+CCA
Chu Guangxi, a Belated Silver Poet of the High Tang
No full textThe Tang dynasty official Chu Guangxi was a well-regarded poet with a place in the literary circle of the eighth century, that most famous era of poetic production known as the High Tang, and yet he was not canonized by posterity in the way that many of his contemporaries were. Perhaps as a direct result of this, there exists no modern critical edition of Chu’s poetry, and very little has been written about him in Western languages. Thus, I offer here an introduction to the life and poetry of Chu Guangxi, a High Tang poet possessing something of a “silver” status. In the course of examining his poetic corpus, I attempt to challenge the one analytical strain that still persists in the majority of Chinese-language scholarship on Chu, namely that his best poetry shows him to be an epigone of the Six Dynasties poet-recluse Tao Qian and a waypoint in the teleological trajectory of pastoral verse. In my reading of Chu’s poems, I find that while some owe an undeniable stylistic debt to Tao Qian, these and many others also evince a strong poetic tension between Chu and his famous reclusive forebear, a tension made manifest in a literary consciousness aswim with the work not just of Tao, but of countless other earlier poets as well. Building on the critical writings of T. S. Eliot and Harold Bloom, I analyze Chu’s poetry as the work of an author who is both conscious of his place in the grand historical matrix of literary tradition, and also working to forge his own poetic identity
