A single epithelial tubule undergoes morphogenesis to form a functional shape during the development of internal organs; however, the mechanical processes that are directed by the molecular signals regulating tubular morphogenesis are poorly understood. Here, axial tubular buckling triggered by cell proliferation is shown to drive the morphogenesis of murine epididymal tubules through mechanica...

In this paper, we study the unobserved vibrations of the head in hard disk drives which may lead to destruction of user data. We show that the acceleration input excites the mechanical resonance near the sampling frequency of the hold in the settling characteristics after the track-seeking control. We also show that the degree to which these oscillations are unobservable depends on the sampling...

Enzymes are molecular machines that bind substrates specifically, provide an adequate chemical environment for catalysis and exchange products rapidly, to ensure fast turnover rates. Direct information about the energetics that drive conformational changes is difficult to obtain. We used subnanometre single-molecule force spectroscopy to study the energetic drive of substrate-dependent lid clos...

the case is 43 years old woman referred to emergency department of our hospital with quadriplegia and severe respiratory insufficiency due to c5-c6 injury after falling. she discharged from icu after fixation of the lesion and successful weaning. we evaluated electrical activity of diaphragm signal (edi), respiratory drive (p100) during one month period. we detected increase in level of electri...

recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. the spherical tours (st) fusion energy development path is complementary to the tokamak burning plasma experiment such as nstx and higher toroidal beta regimes and improves the design of a po...

Piezo1 ion channels mediate the conversion of mechanical forces into electrical signals and are critical for responsiveness to touch in metazoans. The apparent mechanical sensitivity of Piezo1 varies substantially across cellular environments, stimulating methods and protocols, raising the fundamental questions of what precise physical stimulus activates the channel and how its stimulus sensiti...
