Image Reject Patterns in Computed Radiography: Insights From a Ghanaian Radiology Department
Journal of Medical Radiation Sciences, EarlyView.This study examined image rejection patterns in a computed radiography system at a tertiary hospital in Ghana. An overall reject rate of 16.5% was observed, exceeding recommended thresholds, with anatomical cut‐off and positioning errors being the most common causes.

Systematic Error-Correcting Codes for Rank Modulation [PDF]
, 2013 The rank-modulation scheme has been recently proposed for efficiently storing data in nonvolatile memories. Error-correcting codes are essential for rank modulation, however, existing results have been limited.

International Journal of Climatology, EarlyView.Significant trends of precipitation totals are visible at seasonal (negative in spring and positive in winter) and monthly level. The deepening rainfall deficit in April in Western Sudetes threatens the stabilisation of forest ecosystems, the preservation of biodiversity and significantly limits water resources for economic use.

International Journal of Climatology, EarlyView.Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Hierarchical Archimedean Copulas for MATLAB and Octave: The HACopula Toolbox
Journal of Statistical Software, 2020 To extend the current implementation of copulas in MATLAB to non-elliptical distributions in arbitrary dimensions enabling for asymmetries in the tails, the toolbox HACopula provides functionality for modeling with hierarchical (or nested) Archimedean ...

The Pythagorean Won-Loss Formula and Hockey: A Statistical Justification for Using the Classic Baseball Formula as an Evaluative Tool in Hockey [PDF]
, 2013 Originally devised for baseball, the Pythagorean Won-Loss formula estimates the percentage of games a team should have won at a particular point in a season. For decades, this formula had no mathematical justification.

The Laryngoscope, EarlyView.Machine learning algorithms (MLAs) demonstrated significantly higher diagnostic performance than radiologists in detecting extranodal extension (ENE) in head and neck squamous cell carcinoma using CT scans. This meta‐analysis of six studies found that MLAs had a pooled AUC of 0.91, whereas radiologists achieved only 0.65.

A simple non-parametric goodness-of-fit test for elliptical copulas
Dependence Modeling, 2017 In this paper, we propose a simple non-parametric goodness-of-fit test for elliptical copulas of any dimension. It is based on the equality of Kendall’s tau and Blomqvist’s beta for all bivariate margins.

Constipation Is Linked to Neuroinflammation in Early Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Constipation is a risk factor for the onset and accelerated progression of Parkinson's disease (PD), but the mechanisms underlying this association are unknown. Neuroinflammation in PD has been demonstrated in postmortem and neuroimaging studies; however, its relationship with constipation has not been investigated.
