Stellar Ages and an Extended Theory of Gravitation [PDF]

Progress of Theoretical Physics, 1970
Some consequences on stellar ages of the time-varying physical constants as deduced from a modified form of Dirac's hypothesis are discussed. The variation of the gravitational "constant" is shown to be consistent with a Jordan theory of gravitation.

Exercise Capacity, Physical Activity, Fatigue, and Neurocognitive Function in Adult Survivors of Childhood Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at risk of reduced exercise capacity, decreased physical activity levels, persistent fatigue, and neurocognitive deficits. The aim was to investigate exercise capacity and physical activity levels of adult survivors of childhood ALL and their associations with ...

The heavy element mixture and the stellar cluster age

Astrophysics and Space Science, 2006
Recent analyses of solar spectroscopic data (see Asplund, Grevesse & Sauval 2004 and references therein) suggest a significative variation of the heavy elements abundance. The change of heavy mixture might affect the determination of the clusters age for two different reasons: the change of theoretical isochrones at fixed metallicity and the ...

“We Cannot Talk as a Family”: Complexities of Survivorship Communication Among Hispanic/Latino Young Adult Survivors of Childhood Cancer, Parents, and Clinicians

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Young adult childhood cancer survivors (YA‐CCS) have an increased risk of treatment‐related health complications throughout their lives. Lifelong survivorship care is recommended, yet many YA‐CCS experience disruptions in care during pediatric‐to‐adult transitions and do not receive recommended survivorship care.

Stellar Ages for Galactic Archaeology : Methods and Applications [PDF]

, 2021
Galactic Archaeology is the study of the formation and evolution of the Milky Way through the properties of stars and stellar populations. The combination of stellar ages, chemical compositions, positions, and velocities can reveal the history of star ...

Age and metallicity of low-mass galaxies: From their centres to their stellar halos

Astronomy & Astrophysics
Aims. In this work we aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies (M* ≲ 1010 M⊙) to better understand their formation history. Methods.

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...

The Effect of Different Methods for Accounting for α-enhancement on the Asteroseismic Modeling of Metal-poor Stars

The Astrophysical Journal
Constraining stellar models using asteroseismic and spectroscopic observations is a powerful method for precisely determining the fundamental properties of stars in different kinematic components of our Galaxy.
