On construction of the smallest one-sided confidence interval for the difference of two proportions [PDF]

open access: yes, 2010
For any class of one-sided $1-\alpha$ confidence intervals with a certain monotonicity ordering on the random confidence limit, the smallest interval, in the sense of the set inclusion for the difference of two proportions of two independent binomial ...

Correlation between Animal and Mathematical Models for Prostate Cancer Progression

open access: yesComputational and Mathematical Methods in Medicine, Volume 10, Issue 4, Page 241-252, 2009., 2009
This work demonstrates that prostate tumour progression in vivo can be analysed by using solutions of a mathematical model supplemented by initial conditions chosen according to growth rates of cell lines in vitro. The mathematical model is investigated and solved numerically.

A statistical study of COVID-19 pandemic in Egypt

open access: yesDemonstratio Mathematica, 2021
The spread of the COVID-19 started in Wuhan on December 31, 2019, and a powerful outbreak of the disease occurred there. According to the latest data, more than 165 million cases of COVID-19 infection have been detected in the world (last update May 19 ...

Effect of Allocated Radiotherapy after Breast Surgeries over Death Risk in Early Breast Cancer Patients: A Meta‐Analysis

open access: yesComputational and Mathematical Methods in Medicine, Volume 7, Issue 1, Page 45-51, 2006., 2006
Meta‐analysis is a widely used tool to synthesize the results of a set of primary studies leading to more powerful conclusions than those provided by isolated ones. To evaluate the effect of allocated radiotherapy, types of breast surgery and other risk factors over death risk in early breast cancer patients, we carried out a meta‐analysis using ...

Solving the 100 Swiss Francs Problem [PDF]

open access: yes, 2011
Sturmfels offered 100 Swiss Francs in 2005 to a conjecture, which deals with a special case of the maximum likelihood estimation for a latent class model.

On the use of L-functionals in regression models

open access: yesOpen Mathematics, 2023
In this article, we survey and unify a large class or LL-functionals of the conditional distribution of the response variable in regression models.

Comparison of Different Underlying Distributions in The Accelerated Failure Time (AFT) Model on Mortality of Covid-19 Patients

open access: yesInPrime, 2022
In 2022, the COVID-19 virus is still making headlines in various mass media because it is a virus that is very dangerous to health. The world health organization, WHO, explained that the virus caused a global pandemic that infected the whole world.

An Equilibrium Assembly Model Applied to Murine Polyomavirus

open access: yesComputational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 91-93, 2005., 2005
In Keef et al., Assembly Models for Papovaviridae based on Tiling Theory (submitted to J. Phys. Biol.), 2005 [1] we extended an equilibrium assembly model to the (pseudo–)T = 7 viral capsids in the family of Papovaviridae providing assembly pathways for the most likely or primary intermediates and computing their concentrations.

Identification of causal intervention effects under contagion

open access: yesJournal of Causal Inference, 2021
Defining and identifying causal intervention effects for transmissible infectious disease outcomes is challenging because a treatment – such as a vaccine – given to one individual may affect the infection outcomes of others. Epidemiologists have proposed

The Architecture of Viral Capsids Based on Tiling Theory

open access: yesComputational and Mathematical Methods in Medicine, Volume 6, Issue 2, Page 87-90, 2005., 2005
A vital constituent of a virus is its protein shell, called the viral capsid, that encapsulates and hence protects the viral genome. The surface structures of a large number of icosahedral viruses can be modelled via Caspar‐Klug Theory, which has hence become one of the fundamental concepts in virology. However, growing experimental evidence have shown
