Path Planning Algorithm for Manipulators in Complex Scenes Based on Improved RRT.
Sensors (Basel)
January 2025
School of Vehicle and Transportation Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China.
Aiming at the problems of a six-degree-of-freedom robotic arm in a three-dimensional multi-obstacle space, such as low sampling efficiency and path search failure, an improved fast extended random tree (RRT*) algorithm for robotic arm path planning method (abbreviated as HP-APF-RRT*) is proposed. The algorithm generates multiple candidate points per iteration, selecting a sampling point probabilistically based on heuristic values, thereby optimizing sampling efficiency and reducing unnecessary nodes. To mitigate increased search times in obstacle-dense areas, an artificial potential field (APF) approach is integrated, establishing gravitational and repulsive fields to guide sampling points around obstacles toward the target.

Healthcare (Basel)
January 2025
Exercise and Rehabilitation Sciences Institute, Faculty of Rehabilitation Sciences, Universidad Andres Bello, Santiago 7591538, Chile.
: Aging involves a series of changes in non-pathological age-related conditions, some of which impact the cognitive functioning of older adults. Executive functions are cognitive skills that are often affected in this process, although they have been shown to improve after physical exercise interventions. This protocol aims to describe the procedures that will be carried out in a systematic literature review, including a meta-analysis of the effects of resistance interventions on the main dimensions of executive function in cognitively healthy older adults compared to active or passive control groups.

BMC Prim Care
January 2025
College of Health & Medicine, Australian National University, Canberra, Australia.
Background: Strong primary care (PC) services are the foundation of high-performing health care systems and can support effective responses to public health emergencies. Primary care practitioners (PCPs) and PC services played crucial roles in supporting global health system responses to the COVID-19 pandemic. However, these contributions have come at a cost, impacting on PC services and affecting patient care.

Purpose: The aim of this study was to evaluate the feasibility of using patient-specific implants (PSI) for complex shaft corrective osteotomies in multiplanar deformities of long bones in the lower extremities. Additionally, it aimed to investigate the added value of these implants by quantifying surgical accuracy on postoperative CT, comparing their outcomes to two commonly used techniques: 3D virtual visualizations and 3D-printed surgical guides.
Methods: Six tibial and femoral shaft corrective osteotomies were planned and performed on three Thiel embalmed human specimen.
