Errare machinale est: the use of error-related potentials in brain-machine interfaces

The ability to recognize errors is crucial for efficient behavior. Numerous studies have identified electrophysiological correlates of error recognition in the human brain (error-related potentials, ErrPs). Consequently, it has been proposed to use these signals to improve human-computer interaction (HCI) or brain-machine interfacing (BMI). Here, we present a review of over a decade of developm...

Measurement of the Earth's rotation: 720 BC to AD 2015

New compilations of records of ancient and medieval eclipses in the period 720 BC to AD 1600, and of lunar occultations of stars in AD 1600-2015, are analysed to investigate variations in the Earth's rate of rotation. It is found that the rate of rotation departs from uniformity, such that the change in the length of the mean solar day (lod) increases at an average rate of +1.8 ms per century. ...

The western medical tradition: 800 bc to ad 1800

Thirty years ago historians of medicine generally showed little interest in the development of western medicine before the birth of the modern hospital and laboratorybased medical science in the course of the nineteenth century. Although historians might acknowledge the existence of important individuals such as Harvey from an earlier period, these figures were only of interest as precursors of...
