CyTOF. Cytometry by time of flight, or CyTOF, is an application of mass cytometry used to quantify labeled targets on the surface and interior of single cells. CyTOF allows the quantification of multiple cellular components simultaneously using an ICP-MS detector. CyTOF takes advantage of immunolabeling to quantify proteins, carbohydrates or ...
Time of flight. Basic time-of-flight principles applied to laser range-finding. Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about ...
Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.
Daniel Lewin. Daniel Mark Lewin (Hebrew: דניאל "דני" מארק לוין; May 14, 1970 – September 11, 2001) was an American mathematician and entrepreneur who co-founded Akamai Technologies. A passenger on board American Airlines Flight 11, it is believed that Lewin was stabbed to death by Satam al-Suqami, one of the hijackers of that ...
Delayed extraction is a method used with a time-of-flight mass spectrometer in which the accelerating voltage is applied after some short time delay following pulsed laser desorption/ionization from a flat surface of target plate or, in other implementation, pulsed electron ionization or Resonance enhanced multiphoton ionization in some narrow ...
A total of 2,996 were killed on 9/11 and more than 6,000 were injured, according to The Washington Post. The total dead include the hijackers; the plane passengers, pilots and crew; 2,606 people ...
The Hafele–Keating experiment was a test of the theory of relativity. In 1971, [ 1 ] Joseph C. Hafele, a physicist, and Richard E. Keating, an astronomer, took four caesium -beam atomic clocks aboard commercial airliners. They flew twice around the world, first eastward, then westward, and compared the clocks in motion to stationary clocks at ...
Time-of-flight diffraction (TOFD) method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington [1] in 1975 which paved the way for TOFD. Later works on this technique are given in a number of ...
