Implementing Systemic Innovation Strategies for a More Sustainable Future: The Case of Three Overseas Countries and Territories

Frontiers in Research Metrics and Analytics, 2022
Addressing sustainability issues requires a radical systemic change across multiple dimensions, including policy, culture, and civil society. This also implies that no blueprints for governing critical sustainability issues both at the local and global ...

Arches and Culture [PDF]

Nexus Network Journal, 2006
Verf. diskutiert Fragen der Verwendung bzw. der Nichtverwendung des echten Gewölbebogens in der Baugeschichte, insbesondere in Ägypten und Griechenland, und argumentiert, dass hier nicht nur praktische Gesichtspunkte eine Rolle gespielt haben, sondern dass auch das allgemeine kulturelle Umfeld wesentlich war.

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

From Graphic Analysis of Equilibrium to Architectural Design. Cèsar Martinell

Diségno
Graphic statics is a structural calculation method derived from the concept of the thrust line and used by Catalan Modernism. A disciple of Antoni Gaudí, Cèsar Martinell, employed it in the design of 15 wineries between 1918 and 1922, which are now ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

Advanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

Reviving Dead Leaf: Understanding Historical Color Terminology Through Reconstruction

Heritage
The terms fillenoert, villemort, feulje mort, and fillemot are obsolete historical color names derived from the French feuille morte (dead leaf), referred to a broad spectrum of brownish, yellowish, greenish, and reddish hues in early modern textile ...

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these
