Comparison of some Reduced Representation Approximations
In the field of numerical approximation, specialists considering highly
complex problems have recently proposed various ways to simplify their
underlying problems. In this field, depending on the problem they were tackling
and the community that are at work, different approaches have been developed
with some success and have even gained some maturity, the applications can now
be applied to information analysis or for numerical simulation of PDE's. At
this point, a crossed analysis and effort for understanding the similarities
and the differences between these approaches that found their starting points
in different backgrounds is of interest. It is the purpose of this paper to
contribute to this effort by comparing some constructive reduced
representations of complex functions. We present here in full details the
Adaptive Cross Approximation (ACA) and the Empirical Interpolation Method (EIM)
together with other approaches that enter in the same category

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017
Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning
The estimation of digestibility of a new physically modified starch preparation in research on the rats
Celem niniejszej pracy było ustalenie wpływu wysokiego udziału nowego preparatu skrobi modyfikowanej w diecie na wybrane parametry ogólnożywieniowe u szczurów, a w szczególności ocena jego strawności in vivo. Doświadczenie zrealizowano na 20 samcach szczurów białych rasy Wistar w wieku 9 tygodni, którym podawano 2 półoczyszczone diety eksperymentalne z wysokim (50%-owym) udziałem badanych preparatów skrobiowych: preparatu kleikowanej skrobi ziemniaczanej (Solamyl - S) oraz badanej skrobi modyfikowanej na drodze wysokociśnieniowej homogenizacji kleików (H). Spożywanie diety z dużym udziałem preparatu skrobiowego H miało podobny wpływ na parametry wzrostowe i ogólnożywieniowe u szczurów, w tym na ogólną strawność diety, jak w przypadku podawania diety ze skrobią S.
Wysoki udział preparatu skrobi modyfikowanej H w diecie powodował, w porównaniu z preparatem S, przyspieszenie pasażu treści pokarmowej oraz zwiększenie zawartość wody w kale, co może sugerować wpływ degradacji bakteryjnej na uzyskane wyniki strawności.The aim of the work was to determine the effect of a high proportion of a novel modified starch preparation in the diet on selected nutrition parameters in rats, particularly it’s in vivo digestibility. The experiment was conducted on 20 males Wistar white rats, aged 9 weeks, fed 2 semi-purified experimental diets with a high (50%) addition of analyzed starch preparations: gelatinized potato starch preparation (Solamyl - S) and analyzed starch modified by high pressure homogenization of pastes (H). The intake of a diet, with a high addition of starch preparation H, had similar influence on growth and nutritional parameters in rats, including diet digestibility, as in case of feeding of diet with starch S participation. A high addition of new modified starch preparation H in the diet, in comparison with starch S, resulted in transit time acceleration and elevated water feces content, which can indicate an influence of bacterial degradation on digestibility results

Étude de survie du traitement par omalizumab dans une cohorte multicentrique française de patients atteints d’urticaire chronique
L’omalizumab (OMA), anticorps monoclonal anti-IgE, peut être prescrit depuis 2015 en France dans les urticaires chroniques spontanées (UCS) résistantes aux antihistaminiques. Une rémission spontanée est possible et il n’existe pas de recommandation sur la durée optimale de traitement par OMA. Notre objectif était d’évaluer les modalités d’arrêt de l’OMA en vie réelle dans une cohorte multicentrique française
