In condensed matter physics, the dynamic structure factor (or dynamical structure factor) is a mathematical function that contains information about inter-particle correlations and their time evolution. It is a generalization of the structure factor that considers correlations in both space and time.
an outer kinetochore, which interacts with microtubules; the outer kinetochore is a very dynamic structure with many identical components, which are assembled and functional only during cell division. Even the simplest kinetochores consist of more than 19 different proteins.
In condensed matter physics and crystallography, the static structure factor (or structure factor for short) is a mathematical description of how a material scatters incident radiation. The structure factor is a critical tool in the interpretation of scattering patterns ( interference patterns ) obtained in X-ray , electron and neutron ...
From knowledge of elemental structure factors, one can also measure elemental pair correlation functions. See Radial distribution function for further information. Equal-time spin–spin correlation functions are measured with neutron scattering as opposed to x-ray scattering. Neutron scattering can also yield information on pair correlations ...
In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis , a process ...
Haefliger [1] found necessary and sufficient conditions for the existence of a spin structure on an oriented Riemannian manifold (M,g). The obstruction to having a spin structure is a certain element [k] of H 2 (M, Z 2) . For a spin structure the class [k] is the second Stiefel–Whitney class w 2 (M) ∈ H 2 (M, Z 2) of M.
The presence of multiple domains in proteins gives rise to a great deal of flexibility and mobility, leading to protein domain dynamics. [1] Domain motions can be inferred by comparing different structures of a protein (as in Database of Molecular Motions ), or they can be directly observed using spectra [ 13 ] [ 2 ] measured by neutron spin ...
The Rashba effect, also called Bychkov–Rashba effect, is a momentum-dependent splitting of spin bands in bulk crystals [note 1] and low-dimensional condensed matter systems (such as heterostructures and surface states) similar to the splitting of particles and anti-particles in the Dirac Hamiltonian.
