Investigator’s Global Assessment of Chronic Prurigo: A New Instrument for Use in Clinical Trials
Acta Dermato-Venereologica, 2021 Chronic prurigo is a pruritic disease characterized by the development of pruriginous lesions due to scratching. The number of lesions is representative of the stage of the disease, while the presence of excoriations reflects the scratching activity. Aim

Integrated Environmental Assessment and Management, EarlyView., 2023 Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Interpreting Kendall’s Tau and Tau-U for single-case experimental designs
Cogent Psychology, 2018 Tau (τ), a nonparametric rank order correlation statistic, has been applied to single-case experimental designs with promising results. Tau-U, a family of related coefficients, partitions variance associated with changes in trend and level.

Information Entropy Based on Propagation Feature of Node for Identifying the Influential Nodes
Complexity, 2021 For understanding and controlling spreading in complex networks, identifying the most influential nodes, which can be applied to disease control, viral marketing, air traffic control, and many other fields, is of great importance. By taking the effect of

Kendall's tau-type rank statistics in genome data [PDF]
, 2008 summary:High-dimensional data models abound in genomics studies, where often inadequately small sample sizes create impasses for incorporation of standard statistical tools. Conventional assumptions of linearity of regression, homoscedasticity and (multi-

Simulation of potential evapotranspiration values based on vine copula
Meteorological Applications, 2021 Vine copula had a great impact on the study and analysis of dependence structures in various sciences. In multivariate analyses with dimensions of more than two variables, it is associated with computational complexities that solve vine copulas and these

Is CT-based perfusion and collateral imaging sensitive to time since stroke onset?
Frontiers in Neurology, 2015 PurposeCT-based perfusion and collateral imaging is increasingly used in the assessment of patients with acute stroke. Time of stroke onset is a critical factor in determining eligibility for and benefit from thrombolysis. Animal studies predict that the
