Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

Small, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

Probing local atomic structure in thin films by grazing‐incidence total X‐ray scattering with a convergent X‐ray beam

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1420-1425, October 2026.
We performed grazing‐incidence total X‐ray scattering on an indium tin oxide thin film using a convergent incident beam. This approach enables the acquisition of total scattering profiles up to Q = 21 Å−1, demonstrating the feasibility of laboratory instruments for thin film pair distribution function analysis.Grazing‐incidence total X‐ray scattering ...

Enhancing Reference Tracking in Induction Motor Drives: A Hybrid Model Predictive Control and Artificial Neural Network Approach

International Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6719-6738, 25 September 2026.
ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...

Structure design and implementation of a water cooling sub‐20 nm multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline ID23 at HEPS

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1346-1355, September 2026.
A water‐cooling nano multilayer Kirkpatrick–Baez mirrors system has been implemented at ID23 HEPS. The focal spot size of 13.39 nm × 15.15 nm (H × V) at a photon energy of 21.8 keV demonstrates the system's performance.The first water‐cooling nano multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline (ID23) at High Energy Photon

Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, Volume 50, Issue 8, Page 1125-1135, August 2026.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...
