In previous laboratory experiments, we measured the temperature dependence of sticking forces between micrometer grains chondritic composition. The data showed a decrease in surface energy by factor ~5 with increasing temperature. Here, focus on effect water grains. Under ambient conditions laboratory, multiple layers are present. At low pressure protoplanetary discs and for moderate temperatur...

Social learning algorithms provide models for the formation of opinions over social networks resulting from local reasoning and peer-to-peer exchanges. Interactions occur an underlying graph topology, which describes flow information among agents. To account drifting conditions in environment, this work adopts adaptive strategy, is able to track variations signal statistics. Among other results...

Photoplethysmography is a simple measurement of the variation in blood volume in tissue. It detects the pulse signal of heart beat as well as the low frequency signal of vasoconstriction and vasodilation. The transmission type measurement is limited to only a few specific positions for example the index finger that have a short path length for light. The reflectance type measurement can be conv...
