Clinical features of COVID-19 mortality: development and validation of a clinical prediction model
Background The COVID-19 pandemic has affected millions of individuals and caused hundreds of thousands of
deaths worldwide. Predicting mortality among patients with COVID-19 who present with a spectrum of complications
is ...
Predictive validity of the body adiposity index in overweight and obese adults using dual-energy X-ray absorptiometry
(2016)
The body adiposity index (BAI) is a recent anthropometric measure proven to be valid in predicting body fat percentage (BF%) in some populations. However, the results have been inconsistent across populations. This study ...
Endogenous-like orienting of visual attention in rats
(SPRINGER HEIDELBERG, 2011)
This study investigated the orienting of visual attention in rats using a 3-hole nose-poke task analogous to Posner, Information processing in cognition: the Loyola Symposium, Erlbaum, Hillsdale, (1980) covert attention ...
Predicting 13Ca chemical shifts for validation of protein structures
(Springer, 2007-07)
The 13Ca chemical shifts for 16,299 residues from 213 conformations of four proteins (experimentally determined by X-ray crystallography and Nuclear Magnetic Resonance methods) were computed by using a combination of ...
Validity of an adaptation of the framingham cardiovascular risk function: comparison of predicted and observed outcomes with international risk models
Background: Global risk calculation is considered the best tool for community approach of comprehensive cardiovascular (CV) primary prevention, aiding in the establishment of health priorities.
One of the first predictive ...
New approach for proximate analysis by thermogravimetry using CO2 atmosphere: Validation and application to different biomasses
(2017-04-01)
This study investigates the most appropriate conditions to perform the proximate analysis (moisture, volatile matter, fixed carbon, and ash) of biomasses by thermogravimetry, focusing on providing better distinction for ...
Predictive Outcome Validity of General Health Questionnaire (GHQ-28) in Substance Abuse Patients Treated in Therapeutic Communities
Objective: The use of psychoactive substances has been one of the most important global public health problems over the last few decades. Among the problems associated with substance use, dual diagnosis is one of the most ...
Predictability limit of partially observed systems
(Nature, 2020)
Applications from finance to epidemiology and cyber-security require accurate forecasts of dynamic phenomena, which are often only partially observed. We demonstrate that a system's predictability degrades as a function ...
