To Burn-In, or Not to Burn-In: That’s the Question

Aerospace, 2019
In this paper it is shown that the bathtub-curve (BTC) based time-derivative of the failure rate at the initial moment of time can be considered as a suitable criterion of whether burn-in testing (BIT) should or does not have to be conducted.

Computer-modified paramedian approach technique reduces failures and alleviates pain in lumbar puncture: a prospective comparative study

Frontiers in Medicine
BackgroundThe conventional midline approach for lumbar puncture (MAT-LP) has a relatively low success rate of 70%. The paramedian approach can increase the effective puncture area and success rate but lacks standardized guidelines. This study evaluated a
