Classification of four-class motor imagery employing single-channel electroencephalography. [PDF]

open access: yesPLoS ONE, 2014
With advances in brain-computer interface (BCI) research, a portable few- or single-channel BCI system has become necessary. Most recent BCI studies have demonstrated that the common spatial pattern (CSP) algorithm is a powerful tool in extracting ...

Four Channel Assignment Schemes for WiFi in 2.4 GHz Band

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
Nowadays, WiFi is mostly operating in 2.4 GHz band, which allows only 3 non-overlapping channels. For deployment in building it could be a problem to repeat only three channels. In this paper we compare standard three channel scheme (channels 1, 6 and 11)

Evolutionary genomics reveals lineage-specific gene loss and rapid evolution of a sperm-specific ion channel complex: CatSpers and CatSperbeta. [PDF]

open access: yesPLoS ONE, 2008
The mammalian CatSper ion channel family consists of four sperm-specific voltage-gated Ca2+ channels that are crucial for sperm hyperactivation and male fertility. All four CatSper subunits are believed to assemble into a heteromultimeric channel complex,
