In addition to providing structural support, microtubule functions include axoplasmic transport and control of the cell's movement, growth and shape. [31] Orch OR combines the Penrose–Lucas argument with Hameroff's hypothesis on quantum processing in microtubules.
Quantum optical coherence tomography (Q-OCT) is an imaging technique that uses nonclassical (quantum) light sources to generate high-resolution images based on the Hong-Ou-Mandel effect (HOM). [1] Q-OCT is similar to conventional OCT but uses a fourth-order interferometer that incorporates two photodetectors rather than a second-order ...
He was the Mallinckrodt Professor of Physics at Harvard University and Adjunct Professor of Optical Sciences at the University of Arizona. Born in New York City, he was awarded one half of the 2005 Nobel Prize in Physics "for his contribution to the quantum theory of optical coherence ", with the other half shared by John L. Hall and Theodor W ...
Also, the dynein arms attached to the microtubules function as the molecular motors. The motion of the cilia and flagella is created by the microtubules sliding past one another, which requires ATP. [31] They play key roles in: intracellular transport (associated with dyneins and kinesins, they transport organelles like mitochondria or vesicles).
IF-based: The predominant cytoskeletal element within astrocyte processes at birth is microtubules. However, as these cells mature, a significant shift occurs, with microtubules being almost completely replaced by intermediate filaments (IFs), composed predominantly of glial fibrillary acidic protein (GFAP), [ 22 ] found in the end-feet of ...
The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
In his historic paper entitled "The Quantum Theory of Optical Coherence," [1] Roy J. Glauber set a solid foundation for the quantum electronics/quantum optics enterprise. The experimental development of the optical maser and later laser at that time had made the classical concept of optical coherence inadequate. Glauber started from the quantum ...
In physics, coherence theory is the study of optical effects arising from partially coherent light and radio sources. Partially coherent sources are sources where the coherence time or coherence length are limited by bandwidth, by thermal noise, or by other effect. Many aspects of modern coherence theory are studied in quantum optics.
