Concussions can lead to cognitive or neuromotor impairments which may influence skill performance. Few studies have investigated concussion and sports-specific skill performance, particularly in youth. Therefore...

In his July 1984 interview with Michael Cooke, W. H. Winborne described his work with the Orangeburg Area Sickle Cell Anemia Foundation, the Family Health Center, and the outreach programs related to the foundation. Winborne...
Objective: To examine rates of concussion and more severe concussion (time loss of greater than 10 days) in elite 13- to 17-year-old ice hockey players. Methods: This is a prospective cohort study (Alberta, Canada). Bantam...
The first example of enantioselective S‐H insertion reactions of sulfoxonium ylides is reported. Under the influence of thiourea catalysis, excellent levels of enantiocontrol (up to 95% ee) and yields (up to 97%) are achieved...

The neutral hydrogen (H I) content of dark matter haloes forms an intermediate state in the baryon cycle that connects the hot shock-heated gas and cold star-forming gas in haloes. Measurement of the relationship between H I...
Abstract: Searches for CP violation in the two-body decays Ds+→h+π0 and Ds+→h+η (where h+ denotes a π+ or K+ meson) are performed using pp collision data collected by the LHCb experiment corresponding to either 9 fb−1 or 6 fb−1...

Searches for $CP$ violation in the two-body decays $D_{(s)}^{+}\rightarrow
h^{+}\pi^{0}$ and $D_{(s)}^{+} \rightarrow h^{+}\eta$ (where $h^{+}$ denotes a
$\pi^{+}$ or $K^{+}$ meson) are performed using $pp$ collision data...
Abstract: Background/Objective: Current severe traumatic brain injury (TBI) outcome prediction models calculate the chance of unfavourable outcome after 6 months based on parameters measured at admission. We aimed to improve...
Herein, we report the ruthenium-catalyzed ortho C–H alkenylation of a wide range of N-aryloxazolidinone scaffolds. Alkenylation was achieved with complete monoselectivity with a scope of 27 examples in 2-MeTHF. Yields ranged...

Superionic states simultaneously exhibit properties of a fluid and a solid. Proton (H+) superionicity in ice, H3O, He-H2O, and He-NH3 compounds is well-studied. However, hydride (H-) superionicity in H-rich compounds is rare...
