Flash Endurance as Depreciating Capital in Robot Memory

A robot's flash memory endurance is a non-renewable asset that degrades with each write. A wear-aware pricing model introduces a shadow price $η$ to guide memory placement across RAM, NVM, and cloud, with optimal routing depending on the value-write association $χ$. Empirical measurements show $χ$ is positive in long-horizon manipulation, null in short-horizon tasks, and negative in teleoperation, and the endurance budget is binding only on low-end QLC/eMMC memory, where wear-aware control influences routing based on task value without improving performance.

Measurement Gap in EU Law Automation

Large language models can produce median-quality legal text, but no benchmark evaluates their ability to perform doctrinal legal reasoning. This gap undermines the EU AI Act's requirement of 'appropriate accuracy' in judicial AI, as the necessary doctrinal-reasoning evaluation remains absent.

Word2Vec's Performance in Toki Pona's Minimal Vocabulary

This study evaluates Word2Vec's ability to capture semantic relationships in Toki Pona, a language with only 130 words. Using 1.4 million sentences, it finds that non-core tokens do not disrupt embedding structure and may actually bring similar words closer in vector space. The results show Word2Vec's effectiveness relies more on distributional patterns than vocabulary size, even at extreme lexical reduction.

LLM-Generated Stories Show Low Diversity

Large language models produce narratives that are more similar to each other than human-written stories. Frontier models converge on a generic narrative pattern, lacking the diversity found in human-authored stories. Common techniques like negative prompting and temperature scaling do not significantly reduce this homogeneity.
