Where the Blue Stragglers Roam: Searching for a Link Between Formation and Environment [PDF]
Astrophys.J.661:210-221,2007, 2007 The formation of blue stragglers is still not completely understood, particularly the relationship between formation environment and mechanism. We use a large, homogeneous sample of blue stragglers in the cores of 57 globular clusters to investigate the relationships between blue straggler populations and their environments.

Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review
Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022 Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

Blue straggler stars in the globular cluster NGC 5053 [PDF]
The Astrophysical Journal, 1989 A study of the low central concentration globular cluster NGC 5053 based on photometry to 23 mag is reported. Deep C-M diagrams are presented, a mean metal abundance for the cluster is derived from the color of the RGB at the level of the horizontal branch, and theoretical isochrones are used to derive a distance modulus of (m - M0) = 16.05 + or - 0.14

Low‐field MRI: Clinical promise and challenges
Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023 Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

WOCS 4540: Detailed Analysis of a very Long Orbital Period Blue Straggler
The Astrophysical Journal, 2023 WOCS 4540 is the longest orbital period ( P _orb = 3030 days) blue straggler star (BSS)—white dwarf (WD) pair in the old open cluster NGC 188. It also contains one of the most luminous BSS in the cluster.

Blue straggler production in globular clusters [PDF]
Mon.Not.Roy.Astron.Soc. 349 (2004) 129, 2004 Recent HST observations of a large sample of globular clusters reveal that every cluster contains between 40 and 400 blue stragglers. The population does not correlate with either stellar collision rate (as would be expected if all blue stragglers were formed via collisions) or total mass (as would be expected if all blue stragglers were formed via the

Seasonal resource selection and movement ecology of free‐ranging horses in the western United States
The Journal of Wildlife Management, Volume 87, Issue 2, February 2023., 2023 Feral horses selected for areas of high herbaceous vegetation and avoided forest but moved to higher elevations in winter. Surface water influenced movement patterns for harem groups, whereas bachelor males moved faster, farther, and were less constrained by water availability than harems. Because of the importance of surface water, strategic placement

Nonstandard Modeling of a Possible Blue Straggler Star, KIC 11145123 [PDF]
The Astrophysical Journal, 2021 Abstract Nonstandard modeling of KIC 11145123, a possible blue straggler star, has been asteroseismically carried out based on a scheme to compute stellar models with the chemical compositions in their envelopes arbitrarily modified, mimicking the effects of some interactions with other stars through which blue straggler stars are ...

A comparative study on corrosion failure analysis of hearing aid devices from different markets
Materials and Corrosion, Volume 74, Issue 1, Page 159-173, January 2023., 2023 The miniaturized design trend in hearing aids has caused a tremendous reduction in sizes for electronic parts and assembly, and as a result, the robustness of the device towards corrosion‐induced failures is compromised. In this study, a large number of field‐failed hearing aid devices across different markets were analyzed to understand their failure ...
