Knowledge of the radiation transfer through porous materials is important for a variety of engineering systems. In our experiments with layers of packed microparticles on metal, the fraction of light that is directed from normal incidence into waveguided modes is non-negligible; we seek to estimate the absorption in this porous layer with a few, simple experiments. We employ a ray transfer-function approach and provide analytic relations for the reflected, waveguided, and transmitted light. With these relations and multi-modal experimental data taken at different laser wavelengths, the interplay between reflection, waveguiding, and transmission can be estimated. We find that waveguiding is significant when the single-pass absorption of a porous slab is more than a few percent.

Kalberla et al. used HI4PI data to analyze velocity and density fluctuations in the interstellar medium (ISM). They applied the Yuen et al. (2021) velocity decomposition algorithm (VDA) for separating such fluctuations in the position-position-velocity (PPV) space. In the first version of this manuscript they came to the conclusion that velocity and density fields are statistically correlated. Yuen et al. (2021) tried to reproduce these results and pointed to a likely mistake in the VDA expression that was used. We confirm that there was such a software problem. The statement that VDA derived density and velocity fields from HI4PI are anti-correlated needs to be withdrawn. Correct is that these density and velocity fields are uncorrelated. In turn major parts of the conclusions in the first version of this manuscript, based on an erroneous correlation, are invalid. The submission to A&A was withdrawn on 24 February 2022.

« Cours, Forrest, cours ! »... Quand le cinéma encense la marque Nike

Au cœur d’une industrie moderne où la culture populaire s’entremêle avec la culture matérielle, cette étude vise à décrypter, d’un point de vue sémiologique, la présence du langage marketing de Nike à l’intérieur du film Forrest Gump (1994) de Robert Zemeckis. Ce film a été réalisé dans un contexte où les propriétaires de la marque, qui sont remerciés pour leur assistance par les producteurs du film, tentaient de parfaire son image en déposant le nouveau slogan « Just Do It ». Il est donc intéressant d’appréhender la façon dont le réalisateur du film, dans la mise en scène de son personnage principal, Forrest Gump, suggère un lien de causalité entre la pratique du « running » et la chaussure de sport. Du fait de sa forte proéminence audiovisuelle dans l’ensemble du récit, l’histoire de la marque à la virgule se fond dans l’histoire racontée, laquelle contribue à perpétuer in fine sa propre mythologie.

WITHDRAWN ARTICLE: Effect of Sesame Lignan Supplementation on Carotid Intima-Media Thickness, Serum Lipid Profile, Serum VEGF, VCAM-1, ICAM-1 and vWF Levels in Cardiovascular Disease Patients.

Background: Atherosclerosis is a chronic inflammatory disease of the vascular wall which can alter the whole vascular system of both the aorta and coronary arteries. Sesame seeds are one of the richest sources of dietary lignans which exhibit diverse functions and valuable effects such as anti-hypertensive, anti-inflammatory, and anti-oxidative activities. Objectives: In this study, the Effect of sesame lignans on carotid intima-media thickness (CIMT), serum lipid profile, and serum levels of VEGF, VCAM-1, ICAM-1 and vWF were evaluated in cardiovascular (CVD) patients. Methods: In this double-blind, randomized, placebo-controlled clinical trial, thirty-six CVD patients who were candidates for angiography participated for 10 weeks. The subjects were asked to use 500 mg/day sesame lignans (lignan group, n = 19) or placebo (placebo group (starch), n = 17). The CIMT was measured by ultrasound and fasting blood samples were taken before and after the intervention. Results: Sesame lignans supplementation showed a significant decrease in both left and right CIMT, serum lipid profile, fasting blood glucose, and ICAM-1 serum levels compared to baseline and placebo (P < 0.05). Conclusions: These findings indicate that sesame lignans may contribute to the reduction of CIMT and prevent future cardiovascular events and so may be considered as a complementary therapeutic approach in CVD

[WITHDRAWN ARTICLE] A Study on the Performance of Solid Oxide Fuel Cells Based on Pr0.5Sr0.5Co0.8Cu0.2O3–δ-xSDC Composite Cathode

[WITHDRAWN ARTICLE] In this paper, because the new test equipment is used in the test, the debugging problems of the equipment are found in the recent experiments, resulting in the inaccurate test data, which can not reflect the actual results. We are afraid it will mislead the readers and can't explain the characteristics of the battery well. In order to maintain the seriousness of science, the authors of this article hereby apply to withdraw the manuscript and bear all consequences.
