Functional morphology of trabecular bone in the calcaneus of African apes

Journal of Anatomy, EarlyView.
Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

Novel Kinematically Redundant (3+1)-DOF Delta-Type Parallel Mechanisms

Robotics
Although parallel mechanisms are used in various fields, their application is often limited by singularities and a restricted workspace. Kinematic redundancy is a promising approach for mitigating these issues while also extending the functionality of ...

Predictive Value of TMJ Tomographic Parameters for Hypermobility‐Related Outcomes and Mouth Opening Capacity

Journal of Oral Rehabilitation, EarlyView.
Tomographic TMJ parameters showed limited predictive value for hypermobility‐related outcomes. Male sex was consistently associated with greater mouth opening, while increased age reduced the odds of TMJ subluxation. Structural imaging features demonstrated weak associations with functional measures, reinforcing the multifactorial nature of TMJ ...

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

On the danger of redundancies in some aerospace mechanisms [PDF]

An attempt is made to show that redundancies in some aerospace mechanisms do not generally improve the odds for success. Some of these redundancies may even be the very cause for failure of the system. To illustrate this fallacy, two designs based on the

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

A Compact Algorithm for Applying Periodic Boundary Conditions in 3D RVE Modeling with Abaqus

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Periodic boundary conditions (PBCs) are essential in multiscale modeling for computing the effective properties of heterogeneous materials via representative volume elements (RVEs). While several automated solutions have been developed for implementing PBCs in finite element software, many rely on structured node classification and predefined ...

Simultaneous Inversion for Underactuated Mechanical Systems with Servo‐Constraints

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The dynamic inversion of underactuated mechanical systems can be formulated in the servo‐constraint framework using a set of differential‐algebraic equations (DAEs). In case of a high differentiation index, the inversion‐based feedforward control design poses significant challenges.

Machine Learning–Based Cardiovascular Risk Classification Using Dynamic Time‐Series Features From Carotid Duplex Sonography

International Journal of Imaging Systems and Technology, Volume 36, Issue 3, May 2026.
ABSTRACT Although carotid duplex sonography provides comprehensive hemodynamic and morphological information, clinical assessments typically rely on limited static features and flow velocity measurements. This study investigated the feasibility of applying machine learning to classify cardiovascular disease (CVD) risk using dynamic arterial time‐series

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a
