😃 In a new article published in J Biomech, Maarleveld et al. provide an overview on experimentally derived strength parameters, including physiological cross-sectional area, muscle mass, and relative muscle mass.

We took a stab at how to infer both the dynamics and control parameters of partially-observable systems.

It’s a nasty problem, but @vgeadah.bsky.social made tremendous progress, ending up with some really elegant formalisms.
In a system subject to unobserved control, can you infer both the underlying dynamics and the control objective? 🤔

A year ago, I was presenting our work at IEEE CDC on solving this problem for stochastic LQR.
arxiv.org/abs/2502.15014

Short 🧵 on the results, and how I think about them a year later.

Spinal motor neurons in dazzling detail. ✨

Each green dot is a spinal motor neuron - crucial but rare cells making up just 1% of neurons in the spinal cord. In diseases like ALS, they are selectively damaged, making them of special interest to neuroscientists.

Word of the day, should you be feeling a little huffish, is ‘apanthropy’ (18th century): a love of solitude and the desire to be away from other people.

New paper out on @openmindjournal.bsky.social *

I propose balance is a core biophysical self-regulatory function, organisationally akin to thermo-regulation. Might seem radical off the bat, but by the end of the paper I hope you'll agree it seems pretty obvious.

Abstract. Within minutes of birth a newborn gnu or giraffe works to stand and walk, asserting postural balance and organised animate behaviour in an apparently goal-directed manner. In contrast, robot...

How do neural circuits generate the walking rhythm?

Using connectome simulations, @sarahpugly.bsky.social found a minimal central pattern generator (CPG) that produces oscillations in leg motor neurons. Same circuit motif for each 🪰 leg.

In 2020, I started to run every street in Ann Arbor and noticed the Neighborhood Watch signs around town. I was curious and learned that they came out of the 1994 Crime Bill effort for "community policing", and are part of a deeply racist tradition that aims to exclude people that "don't belong".
