There is limited data regarding the effects of melatonin on the
activity of neuronal acetylcholine receptors (nAChRs) themselves. This study
analyzes the effects of low concentrations of melatonin on nicotine-evoked
currents from cerebellar granule neurons (CGNs) in culture. Using
electrophysiological…

Natal dispersal is the time elapsed between departing from the natal site and settling to attempt breeding for the first time. In long-lived species with deferred sexual maturity this period may last several years, making this process crucial for their…

To provide more efficient and flexible alternatives for the applications of secret sharing schemes, this paper describes a threshold sharing scheme based on exponentiation of matrices in Galois fields. A significant characteristic of the proposed scheme is that each participant…

Retinal image quality is commonly analyzed through parameters inherited from instrumental optics. These parameters are defined for ‘good optics’ so they are hard to translate into visual quality metrics. Instead of using point or artificial functions, we propose a quality…
