Background Rates of preterm birth have increased in most industrialised countries but data on later lung function of late preterm births are limited. A study was undertaken to compare lung function at ...

A new configuration for realization of a stabilized bandgap voltage is described. The new two-transistor circuit uses collector current sensing to eliminate errors due to base current. Because the ...

Prior work has shown that smartphone spirometry can effectively measure lung function using the phone’s built-in microphone and could one day play a critical role in making spirometry more usable, ...
