A Stiffness Estimator for Agonistic–Antagonistic Variable-Stiffness-Actuator Devices [PDF]
IEEE Transactions on Robotics, 2014 Safe Physical Human Robot Interaction, conservation of energy and adaptability are just the main robotic applications that prompted the development of a number of Variable Stiffness Actuators (VSA). Implemented in a variety of ways, they use various technologies, and feature the most diverse mechanical solutions, all of which share a fundamentally ...

Variable Volumetric Stiffness Fluid Mount Design
Shock and Vibration, 2004 Passive fluid mounts are commonly used in the automotive and aerospace applications to isolate the cabin from the engine noise and vibration. Due to manufacturing and material variabilities, no two identical fluid mount designs act the same.

Variable-stiffness tensegrity spine [PDF]
Vertebrates, including amphibians, reptiles, birds, and mammals, with their ability to change the stiffness of the spine to increase load-bearing capability or flexibility, have inspired roboticists to develop artificial variable-stiffness spines ...

Design Analysis of a 3-DOF Cable-driven Variable-stiffness Joint Module
, 2015 Variable-stiffness manipulators can produce intrinsically-safe motions, which are essential for next generation service robots. In this paper, the design analysis of a 3-DOF cable-driven joint module with variable stiffness is proposed.

Stiffness modeling of a variable stiffness compliant link
Mechanism and Machine Theory, 2020 Abstract Recently, a variable stiffness robotic link based on the rotating beam concept has been developed for applications in physical human robot interaction. A substantial challenge for design of such links is the modeling of stiffness behavior to permit stiffness control.

Constraint-based equilibrium and stiffness control of variable stiffness actuators [PDF]
2011 IEEE International Conference on Robotics and Automation, 2011 Considerable research effort has gone into the design of variable passive stiffness actuators (VSAs). A number of different mechanical designs have been proposed, aimed at either a biomorphic (i.e., antagonistic) design, compactness, or simplified modelling and control.

FEBS Letters, EarlyView.Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
