TL;DR: This review highlights the recent advances in the field of probiotic beverages both from dairy and non-dairy origin.
Abstract: Nowadays there has been an increased interest in the development of new functional foods and their incorporation in a healthy diet. Such products and especially probiotics exert a beneficial effect on host gut microbiota after consumption and may be capable to prevent several diseases. Fermented beverages are traditional products that act as vehicles of probiotics in human diet. Many studies the last decades have concluded that the best substrates for the delivery of probiotics are dairy products. However lactose intolerance, high fat and cholesterol, milk allergies and also the growing trend of vegetarianism has promoted the research in the field of non-dairy probiotic products. Therefore this review highlights the recent advances in the field of probiotic beverages both from dairy and non-dairy origin.

TL;DR: The second-order statistics and the channel capacity of the Weibull fading channel are studied and exact closed-form expressions are derived for the average level crossing rate, the average fade duration, as well as the average Shannon's channel capacity.
Abstract: The second-order statistics and the channel capacity of the Weibull fading channel are studied. Exact closed-form expressions are derived for the average level crossing rate, the average fade duration, as well as the average Shannon's channel capacity of the Weibull fading process. Numerical results are presented to illustrate the proposed mathematical analysis and to examine the effects of the fading severity on the concerned quantities.

TL;DR: In this paper, the authors used the COBE/DIRBE (1.2, 2.2 and 2.5 µm) maps and the FIRAS spectra to constrain a model for the spatial distribution of the dust, the stars, and the gas in the Milky Way.
Abstract: We use the COBE/DIRBE (1.2, 2.2, 60, 100, 140, and 240 µm) maps and the COBE/FIRAS spectra (for the wavelength range 100−1000 µm) to constrain a model for the spatial distribution of the dust, the stars, and the gas in the Milky Way. By assuming exponential axisymmetric distributions for the dust and the stars and by performing the corresponding radiative transfer calculations we closely (given the simple geometry of the model) reproduce the FIR and NIR maps of the Milky Way. Similar distributions for the atomic and molecular hydrogen in the disk are used (with an inner cut-off radius for the atomic hydrogen) to fit the gas data. The star formation rate as a function of the Galactic radius is derived from the FIR emission and is well in agreement with existing estimates from various star formation tracers. The gas surface density is plotted against the star formation rate density and an “intrinsic” Galactic Schmidt law is derived with excellent agreement with the “external” Schmidt law found for spiral galaxies. The Milky Way is found to consume ∼1% and ∼10% of its gas in the outer and inner regions respectively (for a period of 0.1 Gyr) to make stars. The dust-induced B − V color excess observed in various directions and distances (up to ∼6.5 kpc) with well-studied Cepheid stars is compared with the model predictions showing a good agreement. The simple assumption of exponential distributions of stars and dust in the Galaxy is found to be quite instructive and adequate in modeling all the available data sets from 0.45 µ m( B-band) to 1000 µm.

01 Jul 2005TL;DR: A new learning algorithm for Fuzzy Cognitive Maps, which is based on the application of a swarm intelligence algorithm, namely Particle Swarm Optimization, is introduced, which overcomes some deficiencies of other learning algorithms and improves the efficiency and robustness of FuzzY Cognitive Maps.
Abstract: This paper introduces a new learning algorithm for Fuzzy Cognitive Maps, which is based on the application of a swarm intelligence algorithm, namely Particle Swarm Optimization. The proposed approach is applied to detect weight matrices that lead the Fuzzy Cognitive Map to desired steady states, thereby refining the initial weight approximation provided by the experts. This is performed through the minimization of a properly defined objective function. This novel method overcomes some deficiencies of other learning algorithms and, thus, improves the efficiency and robustness of Fuzzy Cognitive Maps. The operation of the new method is illustrated on an industrial process control problem, and the obtained simulation results support the claim that it is robust and efficient.
