Should heart age calculators be used alongside absolute cardiovascular disease risk assessment? [PDF]
BMC Cardiovascular Disorders, 2018 Background: National estimates of 'heart age' by government health organisations in the US, UK and China show most people have an older heart age than current age. While most heart age calculators are promoted as a communication tool for lifestyle change,

Should Age-Dependent Absolute Risk Thresholds Be Used for Risk Stratification in Risk-Stratified Breast Cancer Screening? [PDF]
Journal of Personalized Medicine, 2021 In risk-stratified cancer screening, multiple risk factors are incorporated into the risk assessment. An individual’s estimated absolute cancer risk is linked to risk categories with tailored screening recommendations for each risk category.

Toward The Absolute Age Of M92 With Mist
, 2016 Globular clusters provide a fundamental link between stars and galaxies. For example, it has been suggested that ultra faint dwarf galaxies formed all of their stars prior to the epoch of reionization, but this conclusion hinges entirely on the striking similarity of their stellar populations to the ancient, metal-poor globular cluster M92.

Absolute Age of Euxenite from Antarctica
Antarctic Record, 1961 南極地方Lutzow-Holm Bayの東海岸,Skallen地区に見出された花崗岩ペグマタイト中の強放射性鉱物,ユークセン石の年令決定を鉛法により行ない,Pb-206/U-238,Pb-207/U-235,Pb-208/Th-232,Pb-207/Pb-206の比を測定することによって年令を算出した.従来,しばしば異常な値を示すと考えられているPb-208/Th-232の比を除けは,他の三つの比から得られる年令は相当によい一致を示し,平均約470×10^5年程度である.最近AHRENSらは著者の一人 ...

Quaternary chronostratigraphy - a review [PDF]
Bulletin of the Geological Society of Finland, 1992 Quaternary development is characterized by strong climatic fluctuations associated with repeated glacier expansions. Consequently the Quaternary chronostratigraphy is largely based on the dating of climatic fluctuations which have led to large-scale ...
