Na-O Anticorrelation And HB I. The Na-O anticorrelation in NGC 2808 [PDF]

, 2005
We derived atmospheric parameters and elemental abundances of Fe, O and Na for about 120 red giant stars in the Galactic globular cluster NGC 2808. Our results are based on the analysis of medium-high resolution (R=22000-24000) GIRAFFE spectra acquired ...

Pollinator Visitation Alters Cranberry Flower Fungal Communities in Wisconsin Cranberry Agroecosystems

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
A two‐year study reveals shared fungal communities between cranberry flowers and insect visitors, including Apis mellifera, Bombus species, solitary bees and hover flies. Greater fungal richness was present in pollinator‐accessible flowers compared to those that were tented.

The connection between missing AGB stars and extended horizontal branches

, 2010
Recent surveys confirm early results about a deficiency or even absence of CN-strong stars on the asymptotic giant branch (AGB) of globular clusters (GCs), although with quite large cluster-to-cluster variations.

Pulsational M_V versus [Fe/H] relation(s) for globular cluster RR Lyrae variables [PDF]

, 2000
We use the results from recent computations of updated non-linear convective pulsating models to constrain the distance modulus of Galactic globular clusters through the observed periods of first overtone RRc pulsators. The resulting relation between the

Factor Analysis of the Neurological Evaluation Scale (NES) and Corresponding Brain Function and Structures

International Journal of Methods in Psychiatric Research, Volume 35, Issue 1, March 2026.
ABSTRACT Objective Neurological soft signs (NSS) are minor, non‐localizable neurological abnormalities. This study aimed to investigate the factor structure of the Neurological Evaluation Scale. Material and Methods A total of 355 subjects (233 patients and 122 general population subjects). NSS were assessed using the NES.

Lithium abundances in globular cluster giants: NGC 6218 (M12) and NGC 5904 (M5)

, 2014
Convergent lines of evidence suggest that globular clusters host multiple stellar populations. It appears that they experience at least two episodes of star formation whereby a fraction of first-generation stars contribute astrated ejecta to form the ...

Episodic Northward Transport Along Nares Strait Brings Anomalously Warm Water Into the Arctic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Nares Strait is one of the primary Arctic export pathways for sea ice and freshwater, connecting the Arctic Ocean to the subpolar North Atlantic. The southward transport along the strait, primarily driven by the higher sea level in the Arctic compared to Baffin Bay, has occasionally been observed to reverse.

Integrated Spectroscopy of Bulge Globular Clusters and Fields. II. Implications for stellar population models and elliptical galaxies [PDF]

, 2002
Synthetic Lick indices (e.g. Mg_2, Fe, etc.) of Simple Stellar Population (SSP) models are calibrated for the first time up to solar metallicity with a sample of Milky Way globular clusters (GCs) which includes the metal rich GCs of the Galactic bulge ...

Evidence for increased background neural noise in migraine with aura: Hyperactive but not hyperresponsive

Headache: The Journal of Head and Face Pain, Volume 66, Issue 3, Page 615-632, March 2026.
Abstract Objective This study had two aims: (1) to investigate the contrast gain in migraine and compare it to that in photosensitive epilepsy; (2) to explore any effects of colored spectacles (precision ophthalmic tints [POT]) on contrast gain. Background Individuals with migraine with aura (MA) typically show high amplitude electrophysiological ...
