Lie great number of lies, depending on how the political wind blows." The question of whether lies can reliably be detected through nonverbal means is a subject of some controversy. Polygraph "lie detector" machines measure the physiological stress a subject endures in a number of measures while he/she gives statements or answers questions. Spikes in stress are purported to indicate lying. The accuracy of this method is widely disputed, and in several well-known cases it was proven to have been deceived. Nonetheless, it remains in use in many areas, primarily as a method for eliciting confessions or employment screening. Polygraph results
Pilatus (detector) ASICs so that the view from the point of view of the crystal is of an unbroken sphere of detector. Pilatus (detector) Pilatus is the name of a series of silicon pixel detectors developed at the Swiss Light Source, and commercialised by Dectris. The common factor is that X-rays are converted to an electrical signal by the photoelectric effect in silicon subject to a substantial bias voltage, and then counted directly by a series of cells in an ASIC bonded to the silicon detector, rather than relying on a phosphor. That is, each pixel has its own amplifier, discriminator (for
