Unavoidability and Functionality of Nervous System and Behavioral Randomness

Applied Sciences
The basic functioning of the central nervous system is based on the opening and closing of ionic channels in the membranes of neurons. The behavior of ionic channels is considered to be a random process with an exponential probability distribution ...

Exponential-Discrete Generalized Exponential Distribution: A New Compound Model [PDF]

Journal of Statistical Theory and Applications (JSTA), 2016
In this paper, the researchers attempt to introduce a new generalization of the exponential distribution. This new model is obtained by compounding the exponential distribution and discrete generalized exponential distribution of a second type, which is ...

A New Generalization of Weighted Geometric Distribution and its Properties [PDF]

Journal of Statistical Theory and Applications (JSTA), 2017
Discrete distributions are widely used to model lifetime for count data. In this paper we introduce a new generalization of weighted geometric (GWG) distribution with the weight function w(x) = (1−p^{αx})^β whose special case proposes a discrete ...

Non-Uniformly Multidimensional Moran Random Walk with Resets

Axioms
In this paper, we investigate the non-uniform m-dimensional Moran walk (Zn(1),…,Zn(m)), where each component process (Zn(j))1≤j≤m, either increases by one unit or resets to zero at each step.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Weighted-Likelihood-Ratio-Based EWMA Schemes for Monitoring Geometric Distributions

Axioms
Monitoring the parameter of discrete distributions is common in industrial production. Also, it is often crucial to monitor the parameter of geometric distribution, which is often regarded as the nonconforming item rate.

Ruin probability analysis in geometric inhomogeneous claims case

Lietuvos Matematikos Rinkinys, 2011
The discrete time risk model with inhomogeneous claims is analyzed. The finite time ruin probability expression is obtained for the case when claims are distributed by geometric distribution with changing parameters.

Geometric Power Lindley Poisson Distribution: Properties and Applications [PDF]

Journal of Statistical Theory and Applications (JSTA), 2016
In this Paper, a new four-parameter distribution motivated mainly by dealing with series-parallel system is introduced. Moments, conditional moments and moment generating function of the new distribution including are presented.
