# s-gst: vortex knots in wave systems

<< Waves  surround  us  all  the  time:  sound waves in  the  noise  around  us, light  waves enabling  us  to see,  and  according  to  quantum  mechanics,  all  matter  has  a  wave  nature.  Most  of  these  waves, however,  do  not  resemble  the  regular  train  of  waves  at  the  shore  of  the  ocean—the  pattern  is much  more  chaotic.  Most  significantly,  the  whirls  and  eddies  form  lines  in  space  called  vortices. Along  these  lines,  the  wave  intensity  is  zero,  and  natural  wave  fields  -  light,  sound  and  quantum matter  -  are  filled  with  a  dense  tangle  of  these  null  filaments >>

# rmx-s-phys: wave's complex exceptional points

<< When  waves  are  able  to  absorb  or  release  energy,  so-called  "exceptional  points"  occur,  around which  the  waves  show  quite  peculiar  behaviour >>

<< Exceptional  points  occur,  when  the  shape  and  the absorption  of  a  system  can  be  tuned  in  such  a  way  that  two  different  waves  can  meet  at  one specific  complex  frequency >>

<< At  this  exceptional  point  the  waves  not  only  share the  same  frequency  and  absorption  rate,  but  also  their  spatial  structure  is  the  same.  One  may thus  really  interpret  this  as  two  wave  states  merging  into  a  single  one  at  the  exceptional  point. >>

<< Unlike self-driving cars which follow well-defined rules, crowds of people have unwritten rules, interacting with each other based on social convention and etiquette, some of which they might not be aware of >>

<< Every country, every culture has its own behaviour and that is why we decided to invent an algorithm which can learn on the fly >>

<< The idea is to create an algorithm which can be used by any robot to learn the social conventions of the place it is in at the time >>

# s-ecol: climate can drive the emergence of different personalities in Anelosimus studiosus (the tangle web spider)

AA << have uncovered an unexpected benefit of (..) personalities [like shyness and aggressiveness]: to protect societies from extreme temperature changes. >>

<< This work focused on the tangle web spider, known to scientists as Anelosimus studiosus, which lives in North Carolina and across North and South America. >>

<< In this species, individual spiders have either one of two personalities: docile or highly aggressive. Together, they not only share the same living space but also share in the duties of brood care and capturing of prey. >>

AA << looked at the effect of temperature – 75 to 93 degrees Fahrenheit – on the spiders' ability to survive and reproduce as an individual and within a colony.  They found that aggressive spiders were less likely to survive and reproduce at higher temperatures. But the opposite was true for docile spiders: as the temperature heated up, the better they reproduced and survived. The researchers saw the same pattern when the colonies were made up of all aggressive individuals or all docile ones. But when a colony had different personalities – a mix of aggressive and docile spiders – the aggressive spiders didn't die in hot temperatures and docile ones didn't die in cooler ones. >>

# n-socsci: a three-level social network among Hunter-Gatherer Societies

<< In both places, individuals maintain a three-tiered social network that appears to buffer them against day-to-day shortfalls in foraging returns. >>

<< First is their immediate household, most often consisting of five or six individuals, second is a cluster of three to four closely related households who share food frequently, and third is the wider camp. >>

<< The test currently can't determine if a person is talking to another human being or a robot if the person being interrogated simply chooses to stay silent >>
