Age differences in the controls of ring doves' pecking
Physiology & Behavior, 1993 Three experiments investigated the endogenous and exogenous controls of ring dove pecking. Experiment 1 confirmed that deprivation modulates adult pecking although nondeprived subjects peak at high levels. Experiment 2 determined that the level of pecking in nondeprived birds is modulated by exogenous cues such as the salience of the seed. Experiment 3

Protoplanetary Disk Rings and Gaps across Ages and Luminosities [PDF]
The Astrophysical Journal, 2019 Abstract Since the discovery of the multiring structure of the HL Tau disk, ALMA data suggest that the dust continuum emission of many, if not all, protoplanetary disks consists of rings and gaps, no matter their spectral type or age. The origin of these gaps so far remains unclear.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...
