Scanning vibrating electrode technique was originally introduced to sensitively measure extracellular currents by Jaffe and Nuccitelli in 1974. [1] Jaffe and Nuccitelli then demonstrated the ability of the technique through the measurement of the extracellular currents involved with amputated and re-generating newt limbs, [5] developmental currents of chick embryos, [6] and the electrical ...
Touch probes differ from a standalone coordinate-measuring machine in that they are typically used on the machine cutting materials. While commonly used in milling machines with automatic tool change systems, touch probes can also be manually swapped with cutting tools and are often paired with a CNC Milling Tool Height Setter for optimized ...
Technology readiness levels were conceived at NASA in 1974 and formally defined in 1989. The original definition included seven levels, but in the 1990s NASA adopted the nine-level scale that subsequently gained widespread acceptance.

Nanoprobe at the Advanced Photon Source, Argonne National Laboratory.. A nanoprobe is an optical device developed by tapering an optical fiber to a tip measuring 100 nm = 1000 angstroms wide.
Navigation of the probe tips in SEM based nanoprobers are typically controlled by precision piezoelectric manipulators. Typical systems have anywhere from 2 to 8 probe manipulators with high end tools having better than 5 nm of placement resolution in the X, Y & Z axes and a high accuracy sample stage for navigation of the sample under test.
Technical translation is a type of specialized translation involving the translation of documents produced by technical writers (owner's manuals, user guides, etc.), or more specifically, texts which relate to technological subject areas or texts which deal with the practical application of scientific and technological information.
A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile. Specific types include test prods, oscilloscope probes and current probes.
TaqMan probes are oligonucleotides that have a fluorescent probe attached to the 5' end and a quencher to the 3' end. During PCR amplification, these probes will hybridize to the target sequences located in the amplicon and as polymerase replicates the template with TaqMan bound, it also cleaves the fluorescent probe due to polymerase 5 ...
