🧠 New paper by Clark et al. (2025) shows that the #dimensionality of #PopulationActivity in #RNN can be explained by just two #connectivity parameters: effective #CouplingStrength and effective #rank. Uses networks with rapidly decaying singular value spectra and structured overlaps between left and right singular vectors. Could be useful for interpreting large scale population recordings and connectome data I guess:

Enhancing electron–#phonon #couplingstrength in low-dimensional strontium ruthenate @advscinews https://onlinelibrary.wiley.com/doi/10.1002/advs.202300012 https://phys.org/news/2023-06-electronphonon-coupling-strength-low-dimensional-strontium.html
Electrons inside crystals interact closely with phonons, defined as the discrete unit of crystal vibrations. The electron–phonon coupling strength is an important fundamental physical quantity in solid state physics, determining electrodynamic behaviors and correlated functionalities of a material. This, in turn, makes for interesting material properties with advanced applications.
