Fair Kernel-Lock-Free Claim/Release Protocol for Shared Object Access in Cooperatively Scheduled Runtimes
We present the first spin-free, kernel-lock-free mutex that cooperates with user-mode schedulers and is formally proven FIFO-fair and linearizable using CSP/FDR. Our fairness oracle and stability-based proof method are reusable across coroutine runtime designs. We designed the claim/release protocol for a process-oriented language -- ProcessJ -- to manage the race for claiming shared inter-process communication channels. Internally, we use a lock-free queue to park waiting processes for gaining…

AutoPR: Let's Automate Your Academic Promotion!
As the volume of peer-reviewed research surges, scholars increasingly rely on social platforms for discovery, while authors invest considerable effort in promoting their work to ensure visibility and citations. To streamline this process and reduce the reliance on human effort, we introduce Automatic Promotion (AutoPR), a novel task that transforms research papers into accurate, engaging, and timely public content. To enable rigorous evaluation, we release PRBench, a multimodal benchmark that l…

Gamma-Ray Spectra of $R$-Process Nuclei
The radioactive decay of unstable nuclei created in the rapid neutron capture process release a large amount of $γ$-rays. When the ejecta is optically thick, these $γ$-rays may contribute to an associated kilonova. Once transparent, prominent spectral features will be directly observable in current and future $γ$-ray detectors. In this work, we study and compare the $γ$-ray spectra of a limited, weak, strong, and extended $r$-process across a broad timescale, identifying the nuclei which si…

J-PLUS: Understanding outlier white dwarfs in the third data release via dimensionality reduction
We present the white dwarf catalog derived from the third data release of the Javalambre Photometric Local Universe Survey (J-PLUS DR3), which covers 3284 deg2 using 12 optical filters. A particular focus is given to the classification of outlier sources. We applied a Bayesian fitting process to the 12-band J-PLUS photometry of white dwarf candidates from Gaia EDR3. The derived parameters were effective temperature, surface gravity, and parallax. We used theoretical models from H- and He-domina…

Slowly moving my openSUSE systems over from Tumbleweed to Tumbleweed Slowroll (a more conservative edition of the TW rolling release). The migration process is painless and well-documented (https://en.opensuse.org/Portal:Slowroll), and the end product is just as pleasant to use as regular Tumbleweed. (…

Probing redshift-dependent systematics in the Hubble tension: Model-independent $H_0$ constraints from DESI R2
We present a model-independent determination of the Hubble constant ($H_0$) using the latest observational data from multiple cosmological probes. By combining baryon acoustic oscillation (BAO) measurements from the second data release of the Dark Energy Spectroscopic Instrument (DESI DR2), cosmic chronometer $H(z)$ data, and the Pantheon Plus Type Ia supernova (SN Ia) sample, we reconstruct the cosmic expansion history through Gaussian process regression without assuming a specific cosmologica…
