# gst: a view of multi-system self-assembly

<< a team of scientists in Turkey has demonstrated the fundamental principles of a universal self-assembly process acting on a range of materials-starting from a few atoms-large quantum dots up to nearly 100 trillion atoms-large human cells. >>

AA << not only demonstrated the self-assembly of simple as well as complex structures that are more than four orders of magnitude different in size and mass. They all come together following a sigmoid function, also known as the S-curve. Curiously, they also observed that the individual deviations from the S-curves follow the statistics of the Tracy-Widom distribution, which manifests in diverse, social, economic, and physical systems.>>

<< To initiate self-assembly, either you force the system to deliver a specific outcome, or you use its inner dynamics to your advantage for universal outcomes. We followed the second approach, >> Serim Ilday.

# ai: the dawn of 'Darwinian' self-programming machines, by Quoc Le (Google)

<< Artificial intelligence (AI) is evolving-literally. Researchers have created software that borrows concepts from Darwinian evolution, including "survival of the fittest," to build AI programs that improve generation after generation without human input. The program replicated decades of AI research in a matter of days, and its designers think that one day, it could discover new approaches to AI. >>

<< So Quoc Le, a computer scientist at Google, and colleagues developed a program called AutoML-Zero that could develop AI programs with effectively zero human input, using only basic mathematical concepts a high school student would know. >>

<< Our ultimate goal is to actually develop novel machine learning concepts that even researchers could not find, >> Quoc Le.

# gst: apropos of strange fluctuations in oscillation and translation

<< The dynamical processes of the inner core rely significantly on the viscous strength of iron. Since plastic deformation of iron may produce crystallographic preferred orientations  (CPO), creep is commonly considered to be a potential source contributing to the seismic anisotropy observed in the inner core. The viscosity of the inner core also influences the rotational dynamics of the Earth. >>

AA << show  that  dislocation  creep  is  a key  mechanism driving  deformation  of  hcp (hexagonal  close  packed) iron  at  inner  core  conditions. The  associated  viscosity  agrees well  with  the  estimates  from  geophysical  observations  supporting  that  the  inner  core  is  significantly less  viscous  than  the  Earth’s  mantle. Such  low  viscosity  rules  out  inner  core  translation,  with  melting on one side  and  solidification  on  the  opposite,  but  allows  for  the  occurrence  of  the  seismically  observed fluctuations  in  inner  core  differential  rotation. >>

# phys: bizarre, cosmic mysteries, when spin particles bump up from 1/2 to 3/2 and more

<< spin is essential when delving into virtually any topic governed by quantum mechanics (..) Yet after almost a century of playing a central role in quantum research, questions about spin remain. For example, why do all the elementary particles that we know about only have spin values of 0, 1/2, or 1? And what new behaviors might exist for particles with spin values greater than 1? The first question may remain a cosmic mystery, but there are opportunities to explore the second. (..)  In the past couple years, researchers have discovered materials in which electrons behave like their spin has been bumped up, from 1/2 to 3/2. (..)  (recently, AA) explored the new behaviors these spins might produce .>>

AA << study, for the first time, the effects of strong short-range electron-electron interactions (..) (they) combine symmetry considerations and a perturbative renormalization group analysis to discern three interacting phases that are prone to emerge in the strongly correlated regime (..) (AA) find that symmetry breaking occurs at weaker coupling if the total monopole charge remains constant across the transition. >>

# life: how humans could mutate, step by step, into proto- alien entities ...

AA << studied the brain after long-duration space flight. The authors performed serial MRI on 11 of 54 eligible International Space Station astronauts (10 men, one woman; five astronauts had previous exposure to spaceflight; mean mission duration almost 6 months), both preflight and at 1 week, 1 month, 3 months, 6 months, and 1 year after spaceflight. They found that prolonged microgravity exposure caused the following brain changes: (a) an approximate 2% expansion of brain and cerebral spinal fluid (CSF) volumes, attributable to both white matter and lateral ventricular measurements, and these remained elevated at 1-year after spaceflight, suggesting permanent alterations; (b) a 13% increase in mean CSF intraventricular (aqueductal) flow velocity, suggesting a reduction in intracranial compliance; and (c) in roughly half (six of 11 astronauts), depression of the pituitary dome compared with baseline (average midline height decreased from 5.9 to 5.3 mm), suggesting elevated intracranial pressure during spaceflight. >>

# gst: unusual properties of substances trapped in nanobubbles.

AA << modeled the behavior of nanobubbles appearing in van der Waals heterostructures and the behavior of substances trapped inside the bubbles. >>

<< The properties exhibited by substances inside the van der Waals nanobubbles are quite unusual. For example, water trapped inside a nanobubble displays a tenfold decrease in its dielectric constant and etches the diamond surface, something it would never do under normal conditions. Argon which typically exists in liquid form when in large quantities can become solid at the same pressure if trapped inside very small nanobubbles with a radius of less than 50 nanometers. >>
