Flexure hinges are widely used for very high precision mechanisms, such as a high precision linear guide, a nano positioning stage, a robot hand and etc., because of no gap FERM PROTEINS VANILLA and no friction.Regarding circular hinge stiffnesses, Paros and Weisbord derived exact solutions, but they are unwieldly because of the complexity.Simpler
The effect of combined action observation therapy and eccentric exercises in the treatment of mid-portion Achilles tendinopathy: study protocol for a feasibility pilot randomised controlled trial
Abstract Background Mid-portion Achilles tendinopathy (AT) is a common overuse injury which can be difficult to successfully rehabilitate.Whilst peripherally directed treatment approaches that strengthen the Achilles tendon complex can be efficacious for some individuals, others will continue to experience long-standing pain and functional deficits
Research progress and prospect of marine carbon sink
The ocean has great potential as a carbon sink.Under the background of global climate change, marine carbon sink is an effective way to build ecological civilization and achieve carbon neutrality in the new era, and has received extensive attention from academia.As an efficient long-term carbon sink, the carbon sink mechanism, carbon sink effect, c
Clinical Study of NeuroRegen Scaffold Combined with Human Mesenchymal Stem Cells for the Repair of Chronic Complete Spinal Cord Injury
Regeneration of damaged neurons and recovery of sensation and motor function after complete spinal cord injury (SCI) are challenging.We previously Round Baker developed a collagen scaffold, NeuroRegen, to promote axonal growth along collagen fibers and inhibit glial scar formation after SCI.When functionalized with multiple biomolecules, this scaff
