Factors governing formation from methyl halogens and pseudohalogens.

The formation of following the double ionization of small organic compounds via a roaming mechanism, which involves the generation of H and subsequent proton abstraction, has recently garnered significant attention. Nonetheless, a cohesive model explaining trends in the yield of characterizing these unimolecular reactions is yet to be established. We report yield and femtosecond time-resolved measurements following the strong-field double ionization of CHX molecules, where X = OD, Cl, NCS, CN, SCN, and I.

Revision Unicompartmental Knee Arthroplasty: Worse Than a Primary, But Better Than a Revision Total Knee Arthroplasty.

Background: Revision of a unicompartmental to a total knee arthroplasty (TKA) is often compared to primary TKA with regard to its technical difficulty and complication rates. We sought to compare medical and surgical complications following revision unicompartmental knee arthroplasty (UKA) to those following primary TKA and aseptic revision TKA.

Methods: A national administrative claims database was queried for patients undergoing revision UKA between 2010 and 2019.

A self-guided e-learning program improves metamemory outcomes in healthy older adults: a randomized controlled trial.

Objectives: Aging brings memory changes that can be concerning for some older adults. Whereas in-person memory interventions can positively impact knowledge, mental health, and behavioural outcomes, self-guided e-learning programs may offer scalable and accessible alternatives to in-person programming. The current study aimed to evaluate efficacy of an e-learning program compared to no treatment.
