The self-organizing nature of ad hoc networks generally has an advantage that the networks are free from fixed infrastructures such as APs (Access points). However, this also has a disadvantage that the networks are unstable and unreliable compared with wired and fixed communication.
Highly efficient high power short pulse lasers at the wavelength range of 2 µm based on Tm3+ doped materials have a variety of applications such as material processing, LiDAR, mid-infrared OPOs for wavelengths up to 12 μm, or mid-infrared supercontinuum generation. They also would enable direct coherent soft X-ray generation by high order harmonics generation.
Social media is expected to be a good source of data for analyzing human behavior and statuses of locations. It is possible to provide location-based information simply by geospatially filtering archived data.
Musical scores for piano usually have a large number of notes and instructions, such as marks indicating expression, articulation, and accidentals. When pianists sight-read sheet music, they must decode such information instantly and transform it into finger actions and movement. However, it is still not clear how pianists are able to achieve such fast decoding.
