Starting from Shannon's definition of dynamic entropy, we proposed a simple theory to describe the transition between different rare event related states in condensed matters, and used it investigate high pressure ice VII. Instead thermodynamic intensive quantities such as temperature pressure, quantity named field is taken controlling variable for transition. Based on entropy versus curve, two...
In the present study, we propose and develop a flexible pressure sensor based on the piezoresistive effect of multilayer graphene films on polyester textile. The pressure response results from the deformation of graphene conductive network structure and the changes in resistance. Here, we show that the graphene pressure sensor can achieve a sensitivity value of 0.012 kPa - 1 , the measurement r...
We determined the effects of static and dynamic muscle contraction at equivalent workloads on central aortic pressure and wave reflection. At random, 14 healthy men and women (23 +/- 5 yr of age) performed a static handgrip forearm contraction [90 s at 30% of maximal voluntary contraction (MVC)], dynamic handgrip contractions (1 contraction/s for 180 s at 30% MVC), and a control trial. During s...
