Article Abstract

Shape-morphing robots can change their morphology to fulfill different tasks in varying environments, but existing shape-morphing capability is not embedded in a robot's body, requiring bulky supporting equipment. Here, we report an embedded shape-morphing scheme with the shape actuation, sensing, and locking, all embedded in a robot's body. We showcase this embedded scheme using three morphing robotic systems: 1) self-sensing shape-morphing grippers that can adapt to objects for adaptive grasping; 2) a quadrupedal robot that can morph its body shape for different terrestrial locomotion modes (walk, crawl, or horizontal climb); 3) an untethered robot that can morph its limbs' shape for amphibious locomotion. We also create a library of embedded morphing modules to demonstrate the versatile programmable shapes (e.g., torsion, 3D bending, surface morphing, etc.). Our embedded morphing scheme offers a promising avenue for robots to reconfigure their morphology in an embedded manner that can adapt to different environments on demand.

Evaluation practices in the French-speaking countries of the West African Economic and Monetary Union (WAEMU) are poorly understood and infrequently documented. Our study is a descriptive analysis that elucidates how stakeholders are conceptualized and involved in evaluation processes in WAEMU. In these countries, evaluators are concerned about the weak stakeholder involvement in evaluation activity and call for greater stakeholder engagement, juxtaposed to the challenges of doing so.

Circuit Modules for Flexible Locomotion.

Annu Rev Neurosci

January 2025

1Department of Neuroscience, Karolinska Institutet, Stockholm, Sweden; email:

Locomotion, like all behaviors, possesses an inherent flexibility that allows for the scaling of movement kinematic features, such as speed and vigor, in response to an ever-changing external world and internal drives. This flexibility is embedded in the organization of the spinal locomotor circuits, which encode and decode commands from the brainstem and proprioceptive feedback. This review highlights our current understanding of the modular organization of these locomotor circuits and how this modularity endows them with intrinsic mechanisms to adjust speed and vigor, thereby contributing to the flexibility of locomotor movements.

Principles for embedding learning and adaptation into New Zealand health system functioning: the example of the Viable System Model.

This article makes the case for taking a model-based management approach, specifically using the Viable System Model (VSM), to embed learning and adaptation into the New Zealand health system so it can function as a learning health system. We draw on a case study of a specialist clinical service where the VSM was used to guide semi-structured interviews and workshops with clinicians and managers and to guide analysis of the findings. The VSM analysis revealed a lack of clarity of organisational functioning, and of the systems, processes and integrated IT infrastructure necessary to support the fundamental requirements of a learning health system.

Background: Periprosthetic joint infections (PJIs) are a major complication of total joint replacement surgeries. This study investigated the enhancement of mechanical properties and antibiotic release in ultra-high molecular weight polyethylene (UHMWPE) through the encapsulation of submicron gentamicin sulfate (GS) particles, addressing the critical need for improved implant materials in orthopaedic surgery, particularly in managing PJIs.

Methods: The present study involved embedding submicron GS particles into UHMWPE flakes at concentrations of 2% to 10% by weight.

Systems biology tackles the challenge of understanding the high complexity in the internal regulation of homeostasis in the human body through mathematical modelling. These models can aid in the discovery of disease mechanisms and potential drug targets. However, on one hand the development and validation of knowledge-based mechanistic models is time-consuming and does not scale well with increasing features in medical data.
