Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, Volume 249, Issue 5, Page 1005-1020, November 2026.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

A Nonlinear Extension of Parametric Model Embedding for Dimensionality Reduction in Parametric Shape Design

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT Dimensionality reduction is essential in simulation‐based shape design, where high‐dimensional parameterizations hinder optimization, surrogate modeling, and systematic design‐space exploration. Parametric Model Embedding (PME) addresses this issue by constructing reduced variables from geometric information while preserving an explicit ...

Evaluation of registration accuracy using short‐arc cone‐beam computed tomography for image‐guided radiotherapy in breast cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Image‐guided radiotherapy (IGRT) using cone‐beam computed tomography (CBCT) enables highly accurate imaging registration; however, increased radiation exposure remains a concern. Recently, short‐arc CBCT (SA‐CBCT), which reduces projection data and reconstructs images, has become available.

Commissioning and end‐to‐end validation of a combined surface‐guided and triggered kV imaging workflow for breath‐hold SBRT on a Varian TrueBeam

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Respiratory motion introduces significant geometric uncertainty in Stereotactic Body Radiotherapy (SBRT) for thoracic and abdominal tumors. Deep Inspiration Breath‐Hold (DIBH) mitigates this, but the surface signal alone may not reflect internal target position, supporting the need for real‐time internal‐anatomy verification during ...

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, Volume 2, Issue 5, October 2026.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...
