Periodic and Chaotic Flapping of Insectile Wings
, 2015 Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of ...

A Generalized Theory of DNA Looping and Cyclization [PDF]
, 2009 We have developed a generalized semi-analytic approach for efficiently computing cyclization and looping $J$ factors of DNA under arbitrary binding constraints. Many biological systems involving DNA-protein interactions impose precise boundary conditions

Power-optimized stiffness and nonlinear position control of an actuator with Variable Torsion Stiffness [PDF]
2013 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2013 Introducing compliant actuation to robotic joints is an approach to ensure safety in closer human-machine interaction. Further, the possibility to adjust stiffness can be beneficial considering energy storage and the power consumption required to track certain trajectories. The subject of this paper is the stiffness and position control of the Variable

Evaluating the cutaneous involvement in scleroderma: torsional stiffness revisited [PDF]
Rheumatology, 2001 The pace, progression and extent of the skin lesions in scleroderma may parallel the risk of new internal organ involvement and the progression of existing internal lesions. Accurate assessment of cutaneous change permits an evaluation of patient prognosis and the response to therapy.
