FCCS is an extension of the fluorescence correlation spectroscopy (FCS) method that uses two fluorescent molecules instead of one that emits different colours. The technique measures coincident green and red intensity fluctuations of distinct molecules that correlate if green and red labelled particles move together through a predefined confocal volume. [2]
A basic diagram of a fluorescence correlation spectroscopy instrument. The typical FCS setup consists of a laser line (wavelengths ranging typically from 405–633 nm (), and from 690–1100 nm (pulsed)), which is reflected into a microscope objective by a dichroic mirror.
In molecular spectroscopy, a Jablonski diagram is a diagram that illustrates the electronic states and often the vibrational levels of a molecule, and also the transitions between them. The states are arranged vertically by energy and grouped horizontally by spin multiplicity . [ 1 ]
Human Design is a pseudoscientific [1] [2] new age practice, described as a holistic self-knowledge system. [3] It combines astrology , the Chinese I Ching , Judaic Kabbalah , Vedic philosophy and modern physics .
Warning label for an electrostatic sensitive device, denoting the devices susceptibility to damage. A similar symbol without the bar and with a black "dome" denotes ESD-safe equipment. The human-body model (HBM) is the most commonly used model for characterizing the susceptibility of an electronic device to damage from electrostatic discharge ...
Human Factors in Engineering and Design has had a significant impact on the field of human factors and ergonomics. The book has helped shape the development of the field and provided a framework for designing human-centered systems. It continues to be a valuable resource for students, researchers, and practicing professionals.
It was based on the same principle as the spectroscope, but it had a camera in place of the viewing tube. In recent years, the electronic circuits built around the photomultiplier tube have replaced the camera, allowing real-time spectrographic analysis with far greater accuracy. Arrays of photosensors are also used in place of film in ...
Diffuse correlation spectroscopy (DCS) is a type of medical imaging and optical technique that utilizes near-infrared light to directly and non-invasively measure tissue blood flow. [1] The imaging modality was created by David Boas and Arjun Yodh in 1995.
