A regime shift in the Southeast Greenland marine ecosystem
Global Change Biology, Volume 29, Issue 3, Page 668-685, February 2023., 2023 The amount of drift‐ice along East Greenland has decreased significantly over the past two decades, and the summer sea ice has virtually disappeared since 2003 leading to a regime shift in oceanographic and ecological conditions in the region. The lack of pack ice in summer together with a warming ocean generated cascading effects on the ecosystem in ...

The spectra and ages of blue stragglers
The Astrophysical Journal, 1985 A mechanism similar to Wheeler's quasi-homogeneous evolution and Finzi and Wolf's proposal for blue stragglers is proposed as the origin of the blue stragglers in intermediate-age clusters. Blue stragglers are stars whose positions in color-magnitude diagrams of open and globular clusters are significantly above the turn-off points and in the region of

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape
The Anatomical Record, EarlyView.Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

Blue Straggler Stars: Early Observations that Failed to Solve the Problem [PDF]
, 2014 In this chapter, I describe early ideas on blue stragglers, and various observations (some published, some not) that promised but failed to resolve the question of their origin. I review the data and ideas that were circulating from Allan Sandage's original discovery in 1953 of "anomalous blue stars" in the globular cluster M3, up until about 1992 ...

Autism Research, EarlyView.ABSTRACT Prior research has established differences between autistic and non‐autistic individuals across the domains of executive function (EF). While some early theories portrayed these differences as universal to the autism spectrum, recent findings have been quite mixed.

Journal of the American Ceramic Society, Volume 106, Issue 2, Page 897-912, February 2023., 2023 States in the process starting with metal oxide nanoparticles in nonequilibrium configurations and ending with functional ceramics that exhibit engineered intergranular regions. Abstract Ion exsolution can be instrumental to engineer intergranular regions inside ceramic microstructures. BaO admixtures that were trapped inside nanometer‐sized MgO grains

Field Blue Stragglers and Related Mass Transfer Issues [PDF]
, 2014 This chapter contains my impressions and perspectives about the current state of knowledge about field blue stragglers (FBS) stars, drawn from an extensive literature that I searched. I conclude my review of issues that attend FBS and mass transfer, by a brief enumeration of a few mildly disquieting observational facts.

Moth light traps perform better with vanes: A comparison of different designs
Journal of Applied Entomology, Volume 146, Issue 10, Page 1343-1352, December 2022., 2022 Abstract Many light trap designs exist in the field of applied and basic entomology for catching moths, yet a robust comparative analysis of structural designs of such traps is lacking. Our study compares the performance of three different trap designs to assess the effect of presence/absence of vanes and their colour on trapping efficiency.
