Anatomic All‐Inside Repair of the Anteroinferior and Posterosuperior Popliteomeniscal Fascicles for Hypermobile Lateral Meniscus

Arthroscopy Techniques, EarlyView.
Abstract Hypermobile lateral meniscus refers to abnormal mobility of an otherwise morphologically normal meniscus without obvious tears, causing lateral knee pain due to catching or locking of the lateral meniscus during flexion. The most common cause is rupture or elongation of the popliteomeniscal fascicles (PMFs), which connect the lateral meniscus ...

Biographies, ontological security and the socio‐spatial politics shaping teachers' mobility in remote Australia

British Educational Research Journal, EarlyView.
Abstract The global teacher shortage continues to intensify, with disparate impacts across geographic and socio‐economic communities. In Queensland, Australia, where this study originates, post‐COVID teacher shortages have intensified workforce pressures, leaving several regional, rural and remote schools as some of the ‘hardest‐to‐staff’ in the ...

Powerful transformations: The experiences of higher education teaching staff who were first‐generation university students

British Educational Research Journal, EarlyView.
Abstract Historically, a university education has been seen primarily as a route for the middle classes to achieve professional qualifications while structural barriers have served to restrict entry to individuals from particular demographics. First‐generation students (FGS), often with low socio‐economic backgrounds, face multiple barriers to Higher ...

Shape‐directed formation of T8/T6 Zn–siloxane clusters and their deep‐UV shielding properties

Bulletin of the Korean Chemical Society, EarlyView.
The shape and conformational characteristics of silane substituents direct the assembly of Zn–siloxane clusters into conventional T8 or rare T6 siloxane frameworks. Non‐planar cyclic substituents selectively promote T6 formation through steric effects, while the resulting clusters exhibit deep‐ultraviolet absorption and can be processed into ...

Voltage Support Capacity Improvement for Wind Farms with Reactive Power Substitution Control

CSEE Journal of Power and Energy Systems
Generally, voltage support at the point of common coupling (PCC) of a wind farm is achieved through centralized static var generators (SVGs). Since the reactive power requirements occupy their capacity in a steady state, the reactive power support ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Flight of the dragons: a global review of migration in Odonata

Biological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.
