The Na-O anticorrelation in horizontal branch stars. III. 47 Tuc and M 5

, 2012
To check the impact of the multiple population scenario for globular clusters on their HB, we present an analysis of the composition of 110 red HB (RHB) stars in 47 Tucanae and of 61 blue HB (BHB) and 30 RHB stars in M5.

Star Formation Histories of Globular Clusters with Multiple Populations. I. \omega\ Cen, M22, and NGC 1851

, 2012
There is increasing evidence that some massive globular clusters (GCs) host multiple stellar populations having different heavy element abundances enriched by supernovae.

Heat Therapy: Targeting Health, Disease, and Disability

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
The predominance of evidence suggests heat therapy has an impact on all aspects of health and performance, but the drivers of that improvement, the extent to which they are improved, and the specific populations in which improvements manifest are far from completely understood.

Infrared photometry of Young Massive Clusters in the starburst galaxy NGC 4214 [PDF]

, 2013
We present the results of an infrared photometric survey performed with NICS@TNG in the nearby starburst galaxy NGC 4214. We derived accurate integrated JK magnitudes of 10 young massive clusters and compared them with the already available Hubble Space ...

Not Even Remotely Close: How Co‐Location Imbalance Affects Subgroup Formation in Hybrid Teams

Journal of Organizational Behavior, Volume 47, Issue 2, Page 192-207, February 2026.
ABSTRACT Despite the substantial proliferation of hybrid work, little has been done to reconcile extant individual‐ and team‐level perspectives. This is problematic because it does not acknowledge how individuals' hybrid work practices constrain team‐level interactions and subsequent outcomes.

The peculiar Horizontal Branch of NGC 2808

, 2010
We present an accurate analysis of the peculiar Horizontal Branch (HB) of the massive Galactic globular cluster NGC 2808, based on high-resolution far-UV and optical images of the central region of the cluster obtained with HST. We confirm the multimodal

The EEG‐Indexed Impacts of Caffeine on Auditory Novelty Processing Across Phases of the Human Menstrual Cycle

European Journal of Neuroscience, Volume 63, Issue 4, February 2026.
Caffeine enhanced auditory novelty processing and attentional ERPs across the menstrual cycle, with the strongest effects observed during the menstrual phase. Increased MMN amplitude and shortened latency under caffeine were accompanied by larger P3b and RON responses and improved behavioural performance.

Self-enrichment in globular clusters. I. An analytic approach

, 2005
By means of analytical calculations, we explore the self-enrichment scenario for Globular Cluster formation. According to this scenario, an initial burst of star formation occurs inside the core radius of the initial gaseous distribution.

Na-O Anticorrelation and HB. IV. Detection of He-rich and He-poor stellar populations in the globular cluster NGC 6218

, 2007
We used the multifiber spectrograph FLAMES on the ESO Very Large Telescope UT2 to derive atmospheric parameters, metallicities and abundances of O and Na for 79 red giant stars in the Galactic globular cluster NGC 6218 (M 12).
