Random Variables Aren’t Random

Mathematics
This paper examines the foundational concept of random variables in probability theory and statistical inference, demonstrating that their mathematical definition requires no reference to randomization or hypothetical repeated sampling. We show how measure-theoretic probability provides a framework for modeling populations through distributions ...

On the Sojourn Time of the Brownian Process in a Multidimensional Sphere

Nonlinear Analysis, 2009
We consider the Brownian motion process B m(s) in the m-space and the distribution F m(t, x, a) = P ˘ sup 0≤s≤t ˛ ˛B m(s) + x ˛ ˛ < a¯ , where a > 0, x ∈ R m, |x| < a.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Physical mechanisms and models of long-term transformations of radiative recombination in n-GaAs due to the magnetic field treatments

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2016
Simulation of long-time changes in photoluminescence of n-GaAs has been performed, and the mechanism of transformation of the defect structure caused by magnetic field treatments has been represented.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

A generalization of the Ricets distribution

Revista Técnica de la Facultad de Ingeniería, 2011
In this paper we generalize the Rice's random variable. We calculate the m-th moment, the distribution function, the characteristic function, the mode and the distribution of the products of Rice's -(a, a, v) random variables.

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

Molecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

Variability Measures of Positive Random Variables

PLoS ONE, 2011
During the stationary part of neuronal spiking response, the stimulus can be encoded in the firing rate, but also in the statistical structure of the interspike intervals. We propose and discuss two information-based measures of statistical dispersion of the interspike interval distribution, the entropy-based dispersion and Fisher information-based ...
