Determination of substrate log-normal distribution in the AZ91/SICP composite

open access: yesMetalurgija, 2015
The aim in this work is to develop a log-normal distribution of heterogeneous nucleation substrates for the composite based on AZ91 alloy reinforced by SiC particles.

Use of Hazard Functions for Determining Power-Law Behaviour in Data

open access: yesAnalytics
Determining the ‘best-fitting’ distribution for data is an important problem in data analysis. Specifically, observing how the distribution of data changes as values below (or above) a threshold are omitted from analyses can be of use in various ...

Positively skewed data: revisiting the box-cox power transformation.

open access: yesInternational Journal of Psychological Research, 2010
Although the normal probability distribution is the cornerstone of applying statistical methodology; data do not always meet the necessary normal distribution assumptions. In these cases, researchers often transform non-normal data to a distribution that

The Log-Rayleigh Distribution for Local Maxima of spectrally Represented Log-normal Processes

open access: yes
We address a novel probability distribution, namely the log-Rayleigh distribution, suited to model the maximum occurring loads in a log-normal process. Log-normal processes in engineering applications can be used to model for example wave or wind loads ...

A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

"Simultaneous estimation of normal precision matrices" [PDF]

open access: yes
This paper treats the problem of simultaneously estimating the precision matrices in multivariate normal distributions. A condition for improvement on the unbiased estimators of the precision matrices is derived under a quadratic loss function.

The log-normal distribution for cascade multiplicities in hadron collisions

open access: yes, 1990
We introduce the log-normal distribution as a simple parametrization of multiplicities in hadron-hadron minimum-bias scattering and show that it fits data at all available energies, including the highest energy (pp̄ at √s=900 GeV) were the negative ...

Paramagnetic Rim Lesions Are Associated With Trans‐Synaptic Degeneration of the Visual Pathway in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

Determination of Variation in Soil Water Storage Capacity on Watersheds

open access: yesJournal of Agricultural Sciences, 2003
The purpose ofthis study is to bring up variation of soil water storage capacity (S) based on probability distributions on vvatersheds, and to compare S obtained from probability distribution to S according to Soil Conservation Service (SCS). İn order to

Dementia Incidence in Individuals With Parkinson's Disease in the Framingham Heart Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Limited information exists on incident dementia in individuals with Parkinson's disease (PD) in US community‐based samples. We examined cognitive statuses and PD diagnoses of 183 individuals in the Framingham Heart Study (FHS) to establish incident dementia, mortality rates, associations with sex, age at PD onset, and education level.
