The contact stress applied from the probe head to the microscale LEDs is 0.91 MPa, which is at least two orders of magnitude lower than the yield stress that will typically create surface defects. We show that the system can perform more than 1 million repeated contact measurements with...

Moreover, synchronies in phenological events can be intra-annual or supra-annual such as that of the multi-year cycles induced by El Niño Southern Oscillation events [89]. Together, this creates a mosaic of individual and community level phenological events that vary across space and through...
The year 1453, when Constantinople was conquered by the Ottomans, is commonly seen as the end of the Byzantine Empire; however, most of the Eastern part of the Roman Empire was lost to the Arabs already in the 7th century, downgrading it to a regional power. Thus, if we speak hereafter...
