Virtual homological torsion: abundance versus growth in books of $I$-bundles
Let $\mathcal{B}$ be a book of $I$-bundles, all of whose pages are surfaces of negative Euler characteristic. In this short note, we prove that torsion in the first homology of $\mathcal{B}$ grows subexponentially in the index along any exhausting tower of regular finite-sheeted covers. By contrast, recent work of Ascari and the author shows that, apart from the obvious exceptions, $\mathcal{B}$ has abundant virtual homological torsion, which can grow exponentially along exhausting towers of no…

Sparse-Autoencoder-Guided Internal Representation Unlearning for Large Language Models
As large language models (LLMs) are increasingly deployed across various applications, privacy and copyright concerns have heightened the need for more effective LLM unlearning techniques. Many existing unlearning methods aim to suppress undesirable outputs through additional training (e.g., gradient ascent), which reduces the probability of generating such outputs. While such suppression-based approaches can control model outputs, they may not eliminate the underlying knowledge embedded in the…

State Field Coverage: A Metric for Oracle Quality
The effectiveness of testing in uncovering software defects depends not only on the characteristics of the test inputs and how thoroughly they exercise the software, but also on the quality of the oracles used to determine whether the software behaves as expected. Therefore, assessing the quality of oracles is crucial to improve the overall effectiveness of the testing process. Existing metrics have been used for this purpose, but they either fail to provide a comprehensive basis for guiding or…

O palhacito do Marques Mendes, a única coisa que tem a dizer sobre a cena do elevador da Glória parece ser que "o Estado falhou".
Parece que lhe passa ao lado (ou por cima, provavelmente) que a manutenção daquilo é agora privada.
O Estado falhou? Talvez, sim, ao passar a manutenção daquilo para mãos privadas, deitando fora trabalhadores com décadas de experiência para poupar uns cobres.
