Mammalian gastrointestinal tract is colonized by a large number of microorganisms, known as gut microbiota, that play a key role in the physiological and pathological states. In particular, the gastrointestinal tract of dogs and cats harbors a complex and highly biodiverse microbial ecosystem. Recent studies see it involved in a wide range of life processes, including energy needs, metabolism, immunological activity, and neuro-behavioral development. This review focuses on the role of the microbiota on the health of pets and will discuss changes that occur in the disease.
In this work we describe an H.261-compatible coder with fuzzy control of the quantization parameters. The quantization parameters are evaluated in order to minimize perceptual distortion and to transmit the images at a fixed bit rate. The fuzzy controller classifies the different areas of the picture according to a set of 28 fuzzy rules using features related to temporal and spatial activity of the sequence. Experimental results show a higher perceptual quality of the new technique when compared to a customary methodology based on the buffer fullness control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
