Apamin Apamin Apamin is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom). Dry bee venom consists of 2–3% of apamin. Apamin selectively blocks SK channels, a type of Ca-activated K channel expressed in the central nervous system. Toxicity is caused by only a few amino acids, these are cysteine, lysine, arginine, arginine and histidine. These amino acids are involved in the binding of apamin to the Ca-activated K channel. Due to its specificity for SK channels, apamin is used as a drug in biomedical research to study the electrical properties of SK channels and their role in the
Spaghetti sort Spaghetti sort Spaghetti sort is a linear-time, analog algorithm for sorting a sequence of items, introduced by Alexander Dewdney in his "Scientific American" column. This algorithm sorts a sequence of items requiring O("n") stack space in a stable manner. It requires a parallel processor. For simplicity, assume we are sorting a list of natural numbers. The sorting method is illustrated using uncooked rods of spaghetti: Preparing the "n" rods of spaghetti takes linear time. Lowering the rods on the table takes constant time, O("1"). This is possible because the hand, the spaghetti rods and the table work as a fully
