Trajectories of Physical Function in Canadian Children with Juvenile Idiopathic Arthritis

Arthritis Care &Research, Accepted Article.
Objectives We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...

Evolution of unconditional dispersal in periodic environments

, 2010
Organisms modulate their fitness in heterogeneous environments by dispersing. Prior work shows that there is selection against "unconditional" dispersal in spatially heterogeneous environments.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Reduced Representation and Whole‐Genome Sequencing Approaches Highlight Beluga Whale Populations Associated to Eastern Canada Summer Aggregations

Evolutionary Applications
Effective conservation strategies inherently depend on preserving populations, which in turn requires accurate tools for their detection. Beluga whales (Delphinapterus leucas) inhabit the circumpolar Arctic and form discrete summer aggregations. Previous

When do beetles and bugs fly? A unified scheme for describing seasonal flight behaviour of highly dispersing primary aquatic insects [PDF]

, 2013
Many authors investigated the dispersal flight of aquatic insects, but the exact length of the seasonal flying periods and its main characteristics have not been determined.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Global distribution and climatic match of a highly traded ornamental freshwater fish, the sailfin molly Poecilia latipinna (Lesueur, 1821)

Knowledge and Management of Aquatic Ecosystems, 2018
Predicting alien species' establishment through climate matching may inform management actions preventing future invasions. The aim of the current study was to evaluate the climate match of the sailfin molly (Poecilia latipinna) worldwide, with emphasis ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Ecological correlates of group integrity among dispersing cliff swallows

Ecosphere, 2019
Breeding colonies of birds represent groups of individuals that associate during one breeding season, at least partially dissociate for the non‐breeding season, and may re‐associate the next year through collective settlement at another breeding site ...
