Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Stochastic Optimization of Non‐Convex Component Solution Spaces

International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT In systems engineering, solution spaces provide a practical way to reconcile competing goals by working with sets of good designs instead of point‐based solutions. Earlier contributions, however, were restricted either by limiting the dimensionality per component or, more recently, by constraining these spaces to be convex, which can, in some ...

Laser‐Enabled Nanopinholes for Silicon Solar Cells with Polycrystalline Si/SiOx Passivating Contacts

Solar RRL, Volume 10, Issue 8, 27 April 2026.
Conductive nanoscale pinholes are created by selective heating of pyramid tips on randomly textured silicon via pulsed laser irradiation. Due to heat concentration at the pyramid tips, the dielectric passivating layer is selectively opened at the pyramid tips.

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...

Muscle performance but not biomechanics associate with second knee injury in a matched cohort of athletes who passed functional return‐to‐sport criteria after ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 3, Page 1118-1130, March 2026.
Abstract Purpose Athletes remain at risk for a second knee injury after anterior cruciate ligament reconstruction (ACLR), even after passing return‐to‐sport (RTS) testing. While biomechanical asymmetries have been linked to reinjury, it is unclear whether deficits persist in athletes who meet RTS criteria.
