Barriers to and enablers of physical activity and its association with daily steps after hospitalisation for a COPD exacerbation: what patients say matters.

Introduction: Exacerbations of COPD decrease physical activity. Physical activity interventions after these events are desirable but have had mixed results. Understanding the barriers to and enablers of physical activity may help to improve the results of these interventions.

First metatarsal osteotomy with an intramedullary locking plate is a good alternative for the reintervention of recurrent hallux valgus.

This study describes the results of first metatarsal (M1) distal osteotomy with an intramedullary locking plate in persistent/recurrent painful hallux valgus (HV) deformity (without advanced degenerative changes) after primary surgery. Outcomes included postoperative incidences of HV angle (HVA)<16°, intermetatarsal angle (IMA)<9°, proximal articular set angle (PASA)<10°, and the American Orthopedic Foot and Ankle Society (AOFAS) score. Data normality was assessed with the Shapiro-Wilk test, and preoperative vs.

Programmable Magnetic Hysteresis in Orthogonally-Twisted 2D CrSBr Magnets via Stacking Engineering.

Twisting 2D van der Waals magnets allows the formation and control of different spin-textures, as skyrmions or magnetic domains. Beyond the rotation angle, different spin reversal processes can be engineered by increasing the number of magnetic layers forming the twisted van der Waals heterostructure. Here, pristine monolayers and bilayers of the A-type antiferromagnet CrSBr are considered as building blocks.

Two coding-complete genomes of porcine reproductive and respiratory syndrome virus 2 (PRRSV-2) from field clinical samples in the Philippines.

We report two coding-complete genome sequences of porcine reproductive and respiratory syndrome virus 2 from field clinical samples obtained in 2021 (BA2021012A) and 2023 (ME20230008B-2) from the Philippines. BA2021012A (15,388 bp) is classified as a lineage L8C strain while ME20230008B-2 (15,513 bp) is a vaccine-like strain in lineage L7.

Stacking-Engineered Ferroelectricity and Multiferroic Order in van der Waals Magnets.

Two-dimensional (2D) materials that exhibit spontaneous magnetization, polarization, or strain (referred to as ferroics) have the potential to revolutionize nanotechnology by enhancing the multifunctionality of nanoscale devices. However, multiferroic order is difficult to achieve, requiring complicated coupling between electron and spin degrees of freedom. We propose a universal method to engineer multiferroics from van der Waals magnets by taking advantage of the fact that changing the stacking between 2D layers can break inversion symmetry, resulting in ferroelectricity as well as magnetoelectric coupling.
