This is a usable training artifact, not a launch claim: the repository supplies PPO and AMP locomotion tasks, single- and multi-GPU training paths, evaluation and ONNX export, supported hardware, and pinned setup dependencies. It documents a walking policy rather than a general robotics stack, but the implementation detail makes it a durable reference for teams evaluating reproducibility in humanoid RL.

NVIDIA’s OpenShell runtime turns operator policy into sandbox limits, while the optional Sentry layer observes and enforces policy from BlueField-4 hardware. The reference design moves a key safety boundary outside the model process; it is a vendor architecture, not evidence that deployed agents are broadly secure.

The paper connects firm-level inflation-forecast accuracy to both Domar weights and price flexibility, then quantifies a network mechanism: endogenous nominal rigidity accounts for about 30% of production networks’ attenuation of monetary-policy shocks. It is preliminary working-paper evidence rather than a completed causal estimate, but the data-and-model bridge gives macro readers something specific to audit.

The first of a three-part series maps the funding chain behind private repo: dealers intermediate, hedge funds are the main cash borrowers, and money market funds the main lenders. Its 2013–25 participant series makes leveraged Treasury funding concrete without claiming a new stress event.

U.S. commercial paper outstanding grew to $1.46 trillion in the week ending Sept. 23, an increase of $19.8 billion from a week earlier, per Federal Reserve data. Commercial paper comprises short-term promissory notes issued mostly by corporations.

FRED reports $1.46 trillion of U.S. commercial paper outstanding for the week ending September 23. The weekly increase is a narrow money-market observation, so it belongs beside broader funding indicators rather than as a standalone growth or credit call.
