Could the logic of life be shaped by the architecture of biological circuitry? In this paper, @manlius.bsky.social shows how genetic, metabolic, and social networks can govern slow evolutionary dynamics in a unified nonequilibrium framework. iopscience.iop.org/article/10.1...

Are Labubus that expensive? Wow!

SFI’s GWCSS program is designed for Ph.D. students pursuing thesis research in computational social science. Participants work closely with peers and faculty to advance their own research and take part in collaborative complexity-based problem solving.

Can a single mathematical edxpression capture the whole spectrum of shapes that can exist? An attempt towards the "super formula" was made in this paper by Johan Gielis, revealing a novel and powerful way to study universal natural forms & phenomena. @manlius.bsky.social @jordipinero.bsky.social

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

I loved this game when I was a kid! (The old one)

Yes, because (in my interpretation):

1) natural language is not precise
2) we take a long time to find the words that make more sense to what is happening in our minds

Illustration of the hypothesized flows of information between perception, memory and cognitive control in a conceptual model of working memory. Stimuli attributes are processed to varying degrees of abstraction and parts of these representations can be loaded into working memory under the guidance of cognitive control. Familiar stimuli such as the letter B activate visually abstract representations while less familiar stimuli are limited to sensory representations. Information can be shifted both up and down levels of the perceptual hierarchy to build either more or less abstract representations of either perceived or imagined stimuli. Working memories can be shifted into or out of the hierarchy as needed.

We recently published a theoretical review about how compositional and generative mechanisms in working memory provide a flexible engine for creative perception and imagery.

“I believe the Data & Code Support Service is incredibly beneficial and important.” “My current research involves computationally intense data analysis, but there’s no centralized support for data quality or management within my lab group or department. Since discovering this service last summer, it has become an essential resource I rely on regularly.” College of Engineering Ph.D. Candidate Kester Wade

As part of his research into energy affordability for U.S. households, a Ph.D. candidate reached out to the Data & Code Support team for help with his data. He was paired with one of our amazing Data & Code consultants, Alfredo González-Espinoza (@spiralizing.bsky.social).

The Open at CMU team at Carnegie Mellon University Libraries supports researchers in making their work more transparent, accessible, and reproducible by providing expertise in open science, open data, open access publishing, and open-source software.

A national study put out by our incredible team of librarians is shedding light on how libraries are keeping up with the fast-changing world of #OpenScience. The study appears last month in The Journal of Academic Librarianship.

The method also identifies non-rich nodes which are crucial for information flows btw rich nodes.

Plus? It has a clear statistical interpretation.
