Pericytes set the tone

The tone is set: a common language for quality

Peripheral signals set the tone for central regulation of metabolism.

In 1849, Claude Bernard suggested that the central nervous system (CNS) regulates blood glucose levels, after his classic experiments showing that “piqûre” (pricking) of the floor of the fourth ventricle of rabbits produced hyperglycemia (1). Remarkably, he speculated that the effect was mediated by stimulation of the sympathetic innervation of the liver. The next major step was the work of Shi...

Fuzzy Set Theoretical Approach to the Tone Triangular System

The present study considers a fuzzy color system in which three input fuzzy sets are constructed on the tone triangle. This system can process a fuzzy input to a tone triangular system and output to a color on the RGB triangular system. Three input fuzzy sets (not black, white, and light) are applied to the tone triangle relationship. By treating three attributes of chromaticness, whiteness, an...

Selection Scheme of the Optimal Tone Set in TR Method

In tone reservation (TR) scheme, it is known that the randomly generated set of peak reduction tones (PRT’s) performs better than the contiguous PRT set and interleaved PRT set in the PAPR reduction of orthogonal frequency division multiplexing (OFDM). It is known that finding the optimal PRT set corresponds to the secondary peak minimization problem in TR scheme. But, the problem is NP-hard be...

Pericytes in the microvasculature.

Pericytes, also known as Rouget cells or mural cells, are associated abluminally with all vascular capillaries and post-capillary venules. Differences in pericyte morphology and distribution among vascular beds suggest tissue-specific functions. Based on their location and their complement of muscle cytoskeletal proteins, pericytes have been proposed to play a role in the regulation of blood fl...
