An Improved QAA-Based Method for Monitoring Water Clarity of Honghu Lake Using Landsat TM, ETM+ and OLI Data

open access: yesRemote Sensing, 2022
Secchi disk depth (ZSD) is used to quantify water clarity as an important water-quality parameter, and one of the most used mechanistic models for ZSD is the quasi-analytical algorithm (QAA), of which the latest version is QAA_v6. There are two models in

Evaluating Dietary Volume Measurements

open access: yesPoultry Science, 1965
Abstract THERE is evidence in the literature which indicates that the control of nutrient intake to provide an adequate but not excessive quantity of each nutrient increases longevity, decreases susceptibility to disease and controls body weight (Berg, 1960; Berg and Simms, 1960; Singsen et al., 1958).

Inconclusive quantum measurements and decisions under uncertainty [PDF]

open access: yes, 2016
We give a mathematical definition for the notion of inconclusive quantum measurements. In physics, such measurements occur at intermediate stages of a complex measurement procedure, with the final measurement result being operationally testable.

Sickle Cell Disease Is an Inherent Risk for Asthma in a Sibling Comparison Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Sickle cell disease (SCD) and asthma share a complex relationship. Although estimates vary, asthma prevalence in children with SCD is believed to be comparable to or higher than the general population. Determining whether SCD confers an increased risk for asthma remains challenging due to overlapping symptoms and the ...
