Fabrication of Lithium/Strontium‐Releasing Smart Bioactive Glasses with Anti‐Inflammatory and Osteogenic Effects Tailored to Pathological Stages

Macromolecular Bioscience, EarlyView.
Bioactive glasses with controllable dual ion release capability are developed to aid bone regeneration. The bioactive glasses rapidly release lithium ions that exert an anti‐inflammatory effect, suppressing inflammation after bone injury. Simultaneously, the bioactive glasses slowly release strontium ions, which support bone formation by suppressing ...

On Generalized Avicenna Numbers

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Avicenna numbers that we define in this paper, are a class of figurate numbers, including icosahedral, octahedral, tetrahedral, dodecahedral, rhombicosidodecahedral numbers and cubes, play a key role in mathematics, physics and various scientific fields.

Estimation of longitudinal and transverse stiffness of hemp fibers and their composites using experimental material parameters and invariants

Polymer Composites, EarlyView.
The utilization of the trace normalized stiffness parameter facilitates direct comparison between natural and non‐natural composites, as it acts as a material parameter. This facilitates the reverse calculation of fiber properties. Abstract The use of hemp is becoming increasingly favored due to its low carbon footprint and biodegradability advantages ...

Capacity building needed to reap the benefits of access to biodiversity collections

PLANTS, PEOPLE, PLANET, EarlyView.
Global conservation efforts increasingly depend on digitised natural history collections, yet the benefits of this digital data are not equally shared. We analysed biodiversity specimens and citation data from Montserrat and the Cayman Islands to assess who collected these specimens, how they are used, and by whom.

Using a Small Hexapod Robot to Pick up Large Cylinders for Munitions Response

Journal of Field Robotics, EarlyView.
ABSTRACT In shallow water environments, traditional technologies face challenges in retrieving unexploded ordnance (UXO). We present an innovative and safe alternative robotic platform to replace traditional divers in this dangerous task. A waterproof 18‐DOF legged robot MR.

A Framework to Enable Eco‐Cyber‐Physical Systems for Robotics‐Focused Digital Twins in Smart Farming

Journal of Field Robotics, EarlyView.
ABSTRACT This paper introduces the R‐ECPS (Robotics‐focused Eco‐Cyber‐Physical System) framework for the development of robotics‐enabled digital twins, integrating human knowledge into the decision‐making process. Our framework adapts ECPS and Digital Twin (DT) definitions to agricultural field robotics.

A Path Planning Algorithm Based on Tangent Point Search and Constrained B‐Spline

Journal of Field Robotics, EarlyView.
ABSTRACT The traditional Tangent Point Search (TPS) algorithm, as a path planning algorithm suitable for large‐scale maps, performs well in the presence of large rectangular obstacles. However, it has two disadvantages: 1. it requires that the obstacles be rectangular so that the shape of obstacles is limited to the fixed form. 2.
