Sigma receptor
CLASS OF CELL SURFACE RECEPTORS RECOGNIZED BY ITS PHARMACOLOGICAL PROFILE
Sigmaergics; Sigmaergic; Sigmamimetic; Sigmamimetics; Sigma agonist; Sigma antagonist; Sigma receptors
Sigma receptors (σ-receptors) are protein cell surface receptors that bind ligands such as 4-PPBP (4-phenyl-1-(4-phenylbutyl) piperidine), SA 4503 (cutamesine), ditolylguanidine, dimethyltryptamine, and siramesine. There are two subtypes, sigma-1 receptors (σ1) and sigma-2 receptors (σ2), which are classified as sigma receptors for their pharmacological similarities, even though they are evolutionarily unrelated.
Detection limit
FOR A GIVEN ANALYTICAL PROCEDURE, CONCENTRATION OR QUANTITY DERIVED FROM THE SMALLEST MEASURE THAT CAN BE DETECTED WITH REASONABLE CERTAINTY
Limit of detection; Limit of Detection; Detection Limits; Limit of quantification; LOQ; Limit of quantitation
The limit of detection (LOD or LoD) is the lowest signal, or the lowest corresponding quantity to be determined (or extracted) from the signal, that can be observed with a sufficient degree of confidence or statistical significance. However, the exact threshold (level of decision) used to decide when a signal significantly emerges above the continuously fluctuating background noise remains arbitrary and is a matter of policy and often of debate among scientists, statisticians and regulators depending on the stakes in different fields.
Sigma SD1
DIGITAL CAMERA MODEL
Sigma SD1 Merrill
The Sigma SD1 is a digital SLR camera produced by the Sigma Corporation of Japan. The camera uses a Foveon X3 sensor, which comprises 3 layers of 4800 x 3200 pixels (46 megapixels), giving much higher chromatic resolution than the equivalent Bayer array.
Wikipedia
Limit set
In mathematics, especially in the study of dynamical systems, a limit set is the state a dynamical system reaches after an infinite amount of time has passed, by either going forward or backwards in time. Limit sets are important because they can be used to understand the long term behavior of a dynamical system. A system that has reached its limiting set is said to be at equilibrium.
