The spectra of $bc\bar{b}\bar{c}$ tetraquark states from a diquark-antidiquark perspective
Within the diquark-antidiquark framework, this study investigates the masses of ground-state tetraquarks composed of heavy charm ($c$) and bottom ($b$) quarks and antiquarks, using the Bethe-Salpeter formalism. We establish the Bethe-Salpeter equations for the fully heavy $bc\bar{b}\bar{c}$ tetraquarks to the leading order in $1/m_Q$ expansion. These equations are subsequently solved numerically under the covariant instantaneous approximation with kernels containing scalar confinement and one-g…

Frankly, They Don’t Give a Damn: “Fair-For-Me-Not-Thee Use” Rulings Leave Artist Consent in Tatters
Early rulings in Bartz v. Anthropic and Kadrey v. Meta sidelined the core of copyright—an author’s right to say no. Defendants brushed off consent (shadow libraries, “transformative” copy-and-train…

RPKT: Learning What You Don't -- Know Recursive Prerequisite Knowledge Tracing in Conversational AI Tutors for Personalized Learning
Educational systems often assume learners can identify their knowledge gaps, yet research consistently shows that students struggle to recognize what they don't know they need to learn-the "unknown unknowns" problem. This paper presents a novel Recursive Prerequisite Knowledge Tracing (RPKT) system that addresses this challenge through dynamic prerequisite discovery using large language models. Unlike existing adaptive learning systems that rely on pre-defined knowledge graphs, our approach rec…
