An Explicit Form of Signum Function
MathematicsIn this paper, the author derives an analytical exact form of signum function, which evidently constitutes a fundamental concept of Communication Systems and Control Theory along with digital control systems and is also involved in many other fields of ...

Atomic diffraction in counter-propagating Gaussian pulses of laser light
, 2007 We present an analysis of atomic diffraction due to the interaction of an atomic beam with a pair of Gaussian light pulses. We derive a simple analytical expression for the populations in different diffraction orders.

Harmonic generation by atoms in circularly polarized two-color laser fields with coplanar polarizations and commensurate frequencies [PDF]
, 2002 The generation of harmonics by atoms or ions in a two-color, coplanar field configuration with commensurate frequencies is investigated through both, an analytical calculation based on the Lewenstein model and the numerical ab initio solution of the time-

Transcriptional Bursting in Gene Expression: Analytical Results for General Stochastic Models. [PDF]
PLoS Computational Biology, 2015 Gene expression in individual cells is highly variable and sporadic, often resulting in the synthesis of mRNAs and proteins in bursts. Such bursting has important consequences for cell-fate decisions in diverse processes ranging from HIV-1 viral ...

Charged-particle orbits near a magnetic null point [PDF]
, 2000 An approximate analytical expression is obtained for the orbits of a charged particle moving in a cusp magnetic field. The particle orbits pass close to or through a region of zero magnetic field before being reflected in regions where the magnetic field

The expansion of the occurrence the source adverb In the Qur'an
الأستاذ, 2015 After the investigation and audit, the researcher found that (expansion) in the language differs from narrowness, in other words, it means idiomatically in the Koran that one expression could have more than one meaning and these meanings are all ...

An Analytic Expression for the Inverse Involute
Mathematical Problems in Engineering, 2019 This article introduces new types of rational approximations of the inverse involute function, widely used in gear engineering, allowing the processing of this function with a very low error. This approximated function is appropriate for engineering applications, with a much reduced number of operations than previous formulae in the existing literature,
