Scaling Relations of Early-Type Galaxies in MOND

Galaxies
We investigate the shape and morphology of early-type galaxies (ETGs) within the framework of Modified Newtonian Dynamics (MOND). Building on our previous studies, which demonstrated that the monolithic collapse of primordial gas clouds in MOND produces ...

Behavioural Determinants of Post‐Brushing Dental Plaque Levels: A Video‐Based Analysis

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives Toothbrushing remains the most widely practiced method for dental plaque removal. However, evidence‐based guidance on optimal brushing method, duration, toothbrush bristle wear, and dentifrice quantity is still insufficient. This study aimed to identify behavioural factors associated with post‐brushing dental plaque levels using ...

Cores of Early-Type Galaxies [PDF]

Symposium - International Astronomical Union, 1987
Systematic study of galaxy cores has become possible through improved understanding of seeing and the reduction of photometric errors by the use of CCDs. Many cores are well resolved in a photometry program with the Canada-France-Hawaii Telescope (median stellar FWHM = 0″.80).

Differences in the Gastric Microbiotas of Neighboring Populations With Divergent Risks of Gastric Cancer

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Background Although Helicobacter pylori plays a central role in gastric cancer (GC), other microorganisms involved in gastric dysbiosis may also impact carcinogenesis. We aimed to characterize gastric dysbiosis and its role in the transition from non‐atrophic gastritis (NAG) to gastric premalignant lesions (GPLs) in two populations from Nariño,

Abundant Molecular Gas in the Central Region of Lenticular Galaxy PGC 39535

The Astrophysical Journal
Lenticular galaxies (S0s) in the local Universe are generally absent of recent star formation and lack molecular gas. In this paper, we investigate one massive ( M _* ∼ 5 × 10 ^10 M _⊙ ) star-forming S0, PGC 39535, with the Northern Extended Millimeter ...

Modular training resources for bioimage analysis

Journal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

Mass Stratification in the Globular Cluster System Revealing the Assembly History of the Nearest S0 Galaxy NGC 3115

The Astrophysical Journal
Galaxy formation and evolution are hierarchical. The most massive galaxies are thought to form their central regions early through violent dissipational processes, then grow inside-out by accreting smaller satellites.

The 40K‐K dating system: 1. Improving data interpretation using new model calculations

Meteoritics &Planetary Science, EarlyView.
Abstract The 40K‐K cosmic‐ray exposure (CRE) dating system offers a promising method for determining exposure ages of iron meteorites by combining the radioactive cosmogenic 40K with the stable cosmogenic isotopes 39K and 41K. However, earlier applications relied on semi‐empirical production models and inconsistent analytical data sets, limiting their ...

The First Exploration of the Correlations Between WISE 12 μm and CO Emission in Early-type Galaxies

The Astrophysical Journal
We present the analysis of a comprehensive sample of 352 early-type galaxies using public data, to investigate the correlations between CO luminosities and mid-infrared luminosities observed by Wide-field Infrared Survey Explorer.
