Many laptops (I know Lenovo at least does this) allow you to charge the battery up to 80% (probably around 3.9-4 volts) and keep it there. This is ideal if you want to use your laptop with AC power, as lithium cobalt batteries lose the least capacity when stored at around 75-80% charge.
A Data and Safety Monitoring Board (DSMB) is an independent group of experts that advises the sponsor and the study investigators. The members of the DSMB serve in an individual capacity and provide their expertise and recommendations. Other names for committees that monitor accumulating data are Data Monitoring Committee (DMC) and Data Safety Monitoring Committee (DSMC).
The Diagnostic and Statistical Manual of Mental Disorders, or DSM for short, is a text that provides the requirements to diagnose a mental disorder, along with statistics and suggested course of treatment for different psychological disorders. The DSM has gone through many revisions, and the most current version is the DSM-5.
