# s-ai: POTUS races: the MogIA's granular prophecies, by Sanjiv Rai

<< An artificial intelligence system that correctly predicted the last three U.S. presidential elections puts Republican nominee Donald Trump ahead of Democrat rival Hillary Clinton in the race for the White House >>

<< MogIA is based on Mowgli, the child from Rudyard Kipling's novel "The Jungle Book." Rai [Sanjiv Rai] said this is because his AI model learns from the environment >>

<< "If you look at the primaries, in the primaries, there were immense amounts of negative conversations that happen with regards to Trump. However, when these conversations started picking up pace, in the final days, it meant a huge game opening for Trump and he won the primaries with a good margin," Rai told CNBC in a phone interview >>

<< Using social media to predict outcomes of elections has become increasingly popular because of the amount of data available publicly. In September, Nick Beauchamp [..] published a paper about his experiment applying AI to more than 100 million tweets in the 2012 election. He found that this closely mirrored the results seen in state-level polling >>

<< Rai said his system would be improved by more granular data  [from] each digital device [..] he could then collect data on exactly what people were thinking >>

# s-gst-music: Hexacorda mollia inside acyclical order and disorder

<< A new composition for string quartet takes listeners on a journey into the weird world of soft matter >>

<< Hexacorda mollia revolves around the theme of order and disorder in soft matter—materials like liquid crystals and biological organisms that can be easily deformed by thermal fluctuations or an external stress, such as an electric or magnetic field. For many of these systems, this form of disorder is required to create ordered structures that can perform some function >>

<< Music is always going through various states of order to disorder and back again, in ways that [scientists] might recognize as phase transitions >>

# s-chem-ethno: nanotech acupuncture needles

<< this experiment [..] combined nanotechnology with acupuncture needles >>

AA << developed porous acupuncture needles (PANs) with fine pores ranging in sizes from nanometers (one billionth of a meter) to micrometers (one millionth of a meter) on the surface of the needles using a nano-electrochemical method >>

<< PANs are expected to be as effective as conventional large and long needles by minimizing the sense of pain during acupuncture treatment while expanding the surface area of the needle 20 times greater than conventional acupuncture ones >>

<< Through electrophysiological experiments with rats [AA] proved that PANs excel in transferring signals from a spinal dorsal horn by the in vivo stimulation of Shenmen (HT7) points, and in particular, demonstrated that the efficacy of PANs is superior to conventional acupuncture needles in treating alcohol and cocaine addiction in animal experiments >>

# s-gst: multiple cracks, simultaneously ...

<< While  the  initiation  of  fracture  in  brittle  solids  is  generally associated  with  the  preexistence  of  material  imperfections,  the mechanism  for  initiation  of  fracture  in  viscoelastic  fluids,  e.g.,  polymer melts  and  solutions,  remains  an  open  question. >>

<< The  images  reveal  the  simultaneous propagation  of  multiple  cracks >>

<< The  critical  stress  and  strain  for  the onset  of  crack  propagation  are  found  to  be  highly  reproducible  functions of  the  stretch  rate,  while  the  position  of  initiation  is  completely  random >>

# s-gst: about internal tides

<< In certain parts of the ocean, towering, slow-motion rollercoasters called internal tides trundle along for miles, rising and falling for hundreds of feet in the ocean's interior while making barely a ripple at the surface >>

<< Internal tides are generated in part by differences in water density, and created along continental shelf breaks, where a shallow seafloor suddenly drops off like a cliff, creating a setting where lighter water meets denser seas. In such regions, tides on the surface produce oscillating, vertical currents, which in turn generate waves below the surface, at the interface between warmer, shallow water , and colder, deeper water >>

<< Now for the first time [AA] have accurately simulated the motion of internal tides along a shelf break called the Middle Atlantic Bight ... >>
