PET Tracer Separation Using Conditional Diffusion Transformer with Multi-latent Space Learning
In clinical practice, single-radiotracer positron emission tomography (PET) is commonly used for imaging. Although multi-tracer PET imaging can provide supplementary information of radiotracers that are sensitive to physiological function changes, enabling a more comprehensive characterization of physiological and pathological states, the gamma-photon pairs generated by positron annihilation reactions of different tracers in PET imaging have the same energy, making it difficult to distinguish t…

Okay, spent a little time with Python's Matplotlib to get this graph of miles biked so far this year...
At some point I should be able to pull the data from Run Gap's SQLite database to automate this more, and get more granular.
I still need to figure out how to space the bars and some other formatting stuff but it's a good start!

“Siloviki” is perhaps the most borrowed word in Russian studies
— probably because it explains so much about Putin’s Russia.
Its members are the police, the border control, the army, the security services, the spies.
For their service to the regime, they are rewarded with early pensions,
plenty of cash and almost total immunity from investigation for corruption or brutality.
In truth, the American security state, with its qualified immunity, surveillance appar…

Opinion | Here’s What’s Happening in America, in Six (Mostly) Russian Terms
To help Americans name their new reality, we wrote a phrase book of authoritarianism.

"As the West debates red lines and escalation risks, Ukraine’s spies are doing what no NATO agency dared: hunting Russian war criminals across three continents, from Moscow’s suburbs to Mali’s deserts — the very territories where Russia projected power unopposed for years.
Russia’s failed blitzkrieg birthed something far more dangerous than Ukrainian resistance — Ukrainian revenge."

Some fun facts about #Python limited API / stable ABI.
1. #CPython supports "limited API". When you use it, you get extensions that are compatible with the specified CPython version and versions newer than that. To indicate this compatibility, such extensions use `.abi3.so` suffix (or equivalent) rather than the usual `.cpython-313-x86_64-linux-gnu.so` or alike.
2. The actual support is split between CPython itself and #PEP517 build systems. For example, if you use #setuptools and specify `py_limited_api=` argument to the extension, setuptools will pass appropriate C compiler flags and swap extension suffix. There's a similar support in #meson, and probably other build systems.
3. Except that CPython freethreading builds don't support stable ABI right now, so building with "limited API" triggers an explicit error from the headers. Setuptools have opted for building explicit about this: it emits an error if you try to use `py_limited_api` on a freethreading interpreter. Meson currently just gives the compile error. This implies that package authors need to actively special-case freethreading builds and enable "limited API" conditionally.
4. A some future versions of CPython will support "limited API" in freethreading builds. I haven't been following the discussions closely, but I suspect that it will only be possible when you target that version or newer. So I guess people will need to be building two stable ABI wheels for a time — one targeting older Python versions, and one targeting newer versions plus freethreading. On top of that, all these projects will need to update their "no 'limited API' on freethreading" conditions.
5. And then there's #PyPy. PyPy does not feature a stable ABI, but it allows you to build extensions using "limited API". So setuptools and meson just detect that there is no `.abi3.so` on PyPy, and use regular suffix for the extensions built with "limited API".

PARROT: Synergizing Mamba and Attention-based SSL Pre-Trained Models via Parallel Branch Hadamard Optimal Transport for Speech Emotion Recognition
The emergence of Mamba as an alternative to attention-based architectures has led to the development of Mamba-based self-supervised learning (SSL) pre-trained models (PTMs) for speech and audio processing. Recent studies suggest that these models achieve comparable or superior performance to state-of-the-art (SOTA) attention-based PTMs for speech emotion recognition (SER). Motivated by prior work demonstrating the benefits of PTM fusion across different speech processing tasks, we hypothesize t…
