Linear and nonlinear stiffness compensation for low-frequency vibration isolation: a comparative study
Quasi-zero stiffness (QZS) vibration isolators show great advantages in low frequency vibration isolation and often developed by compensating the negative stiffness of the bistable structure by linear spring. ...

Open AccessUp-regulation of heat shock protein 27 inhibits apoptosis in lumbosacral nerve root avulsion-induced neurons
Lumbosacral nerve root avulsion leads to widespread death of neurons in the anterior horn area of the injured spinal cord, which results in dysfunction in the lower extremities. Heat shock protein 27 (Hsp27) h...

Changes in weathering effectiveness and community of culturable mineral-weathering bacteria along a soil profile
Bacteria play important roles in mineral weathering, element mobilization, and soil formation. However, little is known about the mineral-weathering bacteria in subsurface soil environments. In this study, a t...
