When Cronbach’s Alpha Is Not Enough: Implications for the Clinical Use of Vision-Related Patient-Reported Outcomes [PDF]

open access: yesVision
Patient-reported outcome measures (PROMs) in vision science are commonly evaluated using Cronbach’s alpha, yet Rasch-based statistics may provide different information about their reliability. This study compared Cronbach’s alpha, a Classical Test Theory

A statistics-based automated flood event separation

open access: yesJournal of Hydrology X, 2021
The classification of characteristics of flood events, like peak, volume, duration and baseflow components is essential for many hydrological applications such as multivariate flood statistics, the validation of rainfall-runoff models and comparative ...

Identification of tagged glycans with a protein nanopore

open access: yesNature Communications, 2023
The structural complexity of glycans seriously challenges the currently available analytical methods. Here, the authors report the identification of glycan isomers, glycans with varying chain lengths, and distinct branched glycans, via a glycan ...

An Interpretable Machine-Learning Algorithm to Predict Disordered Protein Phase Separation Based on Biophysical Interactions

open access: yesBiomolecules, 2022
Protein phase separation is increasingly understood to be an important mechanism of biological organization and biomaterial formation. Intrinsically disordered protein regions (IDRs) are often significant drivers of protein phase separation.

Preparation and Performance of PU/Cpsf Blend Ultrafiltration Membranes for Removal of Heavy Metal Ion Rejection Studies [PDF]

open access: yesEngineering and Technology Journal, 2022
The performance of membranes for a specific application can be determined with the help of structural properties such as molecular weight cut-off (MWCO), morphology, and pore statistics.

Probabilities for separating sets of order statistics [PDF]

open access: yesStatistics, 2009
Consider a set of order statistics that arise from sorting samples from two different populations, each with their own, possibly different distribution functions. The probability that these order statistics fall in disjoint, ordered intervals and that of the smallest statistics, a certain number come from the first populations is given in terms of the ...

A Semi-Automated Statistical Algorithm for Object Separation [PDF]

open access: yesCircuits, Systems, and Signal Processing, 2013
We explicate a semi-automated statistical algorithm for object identification and segregation in both gray scale and color images. The algorithm makes optimal use of the observation that definite objects in an image are typically represented by pixel values having narrow Gaussian distributions about characteristic mean values. Furthermore, for visually

Stochastic dynamics of single molecules across phase boundaries

open access: yesPhysical Review Research, 2021
We discuss the stochastic trajectories of single molecules in a phase-separated liquid, when a dense and a dilute phase coexist. Starting from a continuum theory of macroscopic phase separation we derive a stochastic Langevin equation for molecular ...

Line-Of-Sight Interference Statistics and User Scheduling with 3D Angular Separation

open access: yesInternational Journal of Antennas and Propagation, 2018
We focus on the interference statistical metrics of matched filter transmission over line-of-sight (LoS) downlink channels. The exact moments of the interference are derived, which can be used to make approximations for user rates and gain insights into ...
