A similar analysis can be carried out for any pulse shape, such as the hyperbolic secant-squared (sech 2) pulse profile generated by most ultrashort pulse lasers. If the pulse is of sufficient intensity, the spectral broadening process of SPM can balance with the temporal compression due to anomalous dispersion and reach an equilibrium state.
Statistical parametric mapping (SPM) is a statistical technique for examining differences in brain activity recorded during functional neuroimaging experiments. It was created by Karl Friston . It may alternatively refer to software created by the Wellcome Department of Imaging Neuroscience at University College London to carry out such analyses.
In physics, statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. Sometimes called statistical physics or statistical thermodynamics, its applications include many problems in the fields of physics, biology, [1] chemistry, neuroscience, [2] computer science, [3] [4] information theory [5] and ...
For example, in a very small system with N = 2 dipoles, there are three macrostates, corresponding to =,, Since the N ↑ = 0 {\displaystyle N_{\uparrow }=0} and N ↑ = 2 {\displaystyle N_{\uparrow }=2} macrostates require both dipoles to be either anti-aligned or aligned, respectively, the multiplicity of either of these states is 1.
In theoretical physics, statistical field theory (SFT) is a theoretical framework that describes phase transitions. [1] It does not denote a single theory but encompasses many models, including for magnetism, superconductivity, superfluidity, [2] topological phase transition, wetting [3] [4] as well as non-equilibrium phase transitions. [5]
The Sijil Pelajaran Malaysia (SPM), or the Malaysian Certificate of Education, is a national examination sat for by all Form 5 secondary school students in Malaysia.It is the equivalent of the General Certificate of Secondary Education (GCSE) of England, Wales and Northern Ireland; the Nationals 4/5 of Scotland; and the GCE Ordinary Level (O Level) of the Commonwealth of Nations.
astrophysics, the physics in the universe, including the properties and interactions of celestial bodies in astronomy; atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System
Fermi–Dirac statistics is a type of quantum statistics that applies to the physics of a system consisting of many non-interacting, identical particles that obey the Pauli exclusion principle. A result is the Fermi–Dirac distribution of particles over energy states .
