Variational Analysis in Spectral Decomposition Systems
This work is concerned with variational analysis of so-called spectral functions and spectral sets of matrices that only depend on eigenvalues of the matrix. Based on our previous work [H. T. Bùi, M. N. Bùi, and C. Clason, Convex analysis in spectral decomposition systems, arXiv 2503.14981] on convex analysis of such functions, we consider the question in the abstract framework of spectral decomposition systems, which covers a wide range of previously studied settings, including eigenvalue de…

Globe and Mail columnist Andrew Coyne, who I always thought of as one of the more dogmatically right-wing columnists in Canadian media back when I lived there 20 years ago, delivers one of the most lucid and comprehensive analyses of Trump and his so-called administration I have seen.

Spectral analysis of hierarchical continuous-time quantum walks
In this paper, we introduce hierarchical random walks at first. In this model, we use two types of random walkers, {global and local} walkers. The global walker chooses a local walker at every step, then the chosen local walker moves a single step. After that we construct the corresponding continuous-time quantum walks and discuss its spectral structures. Then we define multi-dimensional continuous-time quantum walk by taking a marginal distribution respect to the global walker.

Abundances of Rarely Detected s-process Elements Derived from the Ultraviolet Spectrum of the s-process-enhanced Metal-poor Star HD 196944
We present an analysis of the heavy-element abundances of HD 196944, a carbon-enhanced metal-poor (CEMP) star enriched with elements produced by the slow neutron-capture process (s-process). We obtained a new high-resolution ultraviolet (UV) spectrum of this star, the UV-brightest known CEMP-s star, with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. This spectrum extends deeper into the UV (2029 < lambda < 2303 Angstroms) than previous studies of any CEMP-s star.…

Cost Analysis of Human-corrected Transcription for Predominately Oral Languages
Creating speech datasets for low-resource languages is a critical yet poorly understood challenge, particularly regarding the actual cost in human labor. This paper investigates the time and complexity required to produce high-quality annotated speech data for a subset of low-resource languages, low literacy Predominately Oral Languages, focusing on Bambara, a Manding language of Mali. Through a one-month field study involving ten transcribers with native proficiency, we analyze the correction …

Saw a clip of a preacher retelling an anecdote about a chess grandmaster being shown a painting of the devil having apparently defeated his opponent at chess for his soul. The grandmaster studied the painting and saw that there was still a path to avoid a checkmate. So the painting contained a secret inspirational message of hope!
Yet when people accurately model the game state from Die Schachspieler and feed it into chess analysis algorithms, Mephistopheles always wins

Game of Life - Board position and Paul Morphy - Chess Forums
There is an painting "Checkmate" that depicts Satan playing against a young man. The board position is supposed to appear hopeless but it is said that Paul Morphy when seeing the painting studied the picture, called for a chess board to be set up and some time after declared the young man has not yet...

Claude skills are a big deal™️
Thanks to skills, you can reduce your multi-agent setup to a single agent with skills, greatly reducing complexity and increasing speed of execution.
In fact, if in the past you could have a number of agents each specialized in, for example, data analysis, getting data from a particular set of websites, making that data available in a dashboard, etc., with skills you can substitute all these agents with skills. (1/2)
