Effects of localization and amplification on distribution of intensity transmitted through random media [PDF]
, 2004 We numerically study the statistical distribution of intensity transmitted through quasi-one dimensional random media by varying the dimensionless conductance $g$ and the amount of absorption or gain.

Rayleigh-Based Distributed Optical Fiber Sensing
Sensors, 2022 Distributed optical fiber sensing is a unique technology that offers unprecedented advantages and performance, especially in those experimental fields where requirements such as high spatial resolution, the large spatial extension of the monitored area, and the harshness of the environment limit the applicability of standard sensors.

Sub-Rayleigh resolution of two incoherent sources by array homodyning
, 2020 Conventional incoherent imaging based on measuring the spatial intensity distribution in the image plane faces the resolution hurdle described by the Rayleigh diffraction criterion.

Intensity Fluctuations in Closed and Open Systems
, 1996 We consider the intensity pattern, generated by a monochromatic source, in a disordered cavity coupled to the environment. For weak coupling, and when the source frequency is tuned to a resonance, the intensity distribution is close to Porter-Thomas ...

Protoplanet Dynamics in a Shear-Dominated Disk [PDF]
, 2006 The velocity dispersion, or eccentricity distribution, of protoplanets interacting with planetesimals is set by a balance between dynamical friction and viscous stirring.

Truncated Rayleigh Pareto Distribution
Journal of Physics: Conference Series, 2020 Abstract In this paper, we introduced a new distribution which is the truncated Rayleigh Pareto distribution of a variable, and some useful functions, and some mathematical and statistical properties such as density function, the cumulative distribution function, limit function, reliability function, hazard function, stress - strength ...

Stable Equilibrium Based on L\'evy Statistics: Stochastic Collision Models Approach
, 2003 We investigate equilibrium properties of two very different stochastic collision models: (i) the Rayleigh particle and (ii) the driven Maxwell gas. For both models the equilibrium velocity distribution is a L\'evy distribution, the Maxwell distribution ...

Non‐Rayleigh Statistics of Ultrasonic Backscattered Echo from Tissues [PDF]
, 1994 The envelope of the backscattered signal from tissues can exhibit non‐Rayleigh statistics if the number density of scatterers is small or if the variations in the scattering cross sections are random. The K distribution which has been used extensively in

, 1999 We propose an information-theoretic model for the transport of waves through a chaotic cavity in the presence of absorption. The entropy of the S-matrix statistical distribution is maximized, with the constraint $ =\alpha n$: n is the dimensionality of S,

Consistency of a Causal Theory of Radiative Reaction with the Optical Theorem [PDF]
, 2011 The Abraham-Lorentz-Dirac equation for a point electron, while suffering from runaway solutions and an acausal response to external forces, is compatible with the optical theorem.
