Unlocking Exponential and Unbounded Robust Gains in Shannon Capacity of Classical Multiple Access Channels with Causal CSIT via Quantum Entanglement Assistance
arXiv:2606.05412v1 Announce Type: new Abstract: Quantum entanglement assistance is known to improve the Shannon capacity of classical communication networks but the largest gains noted thus far are rather modest (less than 6%), motivating the question: are large capacity gains ever possible? It is shown in this work that in the presence of causal channel state information at the transmitters, quantum entanglement assistance provides a multiplicative capacity advantage that grows...
Algebraic Diversity: Principles of a Group-Theoretic Approach to Signal Processing
arXiv:2604.19983v5 Announce Type: replace-cross Abstract: We present principles of algebraic diversity (AD), a group-theoretic approach to signal processing exploiting signal symmetry to extract more information per observation, complementing classical methods that use temporal and spatial diversity. The transformations under which a signal's statistics are invariant form a matched group; this group determines the natural transform for analysis, and averaging an estimator over the group...
Topic modeling reveals thermally partitioned and taxonomically distinct microbial subcommunities across prokaryotes and phytoplankton in the Laurentian Great Lakes
Identifying discrete microbial assemblages and their environmental drivers across multiple biological fractions simultaneously remains a central challenge in aquatic microbial ecology. We applied an integrated analytical pipeline built around Latent Dirichlet Allocation (LDA) to an eight-year 16S rRNA amplicon time series from the Laurentian Great Lakes, spanning four size-fractionated biological blocks free-living prokaryotes, particle-associated prokaryotes, and small and large...
Not All Points Are Equal: Uncertainty-Aware 4D LiDAR Scene Synthesis
arXiv:2606.02510v1 Announce Type: new Abstract: Constructing faithful 4D worlds from LiDAR-acquired sequences is crucial for embodied AI, yet current generative frameworks apply uniform modeling capacity across all spatial regions. This ignores that perceptual difficulty varies dramatically within a single scan: distant surfaces, occluded boundaries, and small-scale objects carry far higher uncertainty than well-observed structures. We present U4D, a new framework that explicitly leverages...
The people who actually want AI to replace humanity
“I want AI to be a tool that allows human flourishing!” exclaimed Brad Carson, a former member of Congress. “There is an option out there where AI is just a tool for us.” The people who actually want AI to replace humanity We need to create a new humanism before the “AI successionists” win.
Anguished Parents, Crying Doctors: Life Amid Utah’s Measles Outbreak
Ben Dowse hadn’t expected to treat measles when he became a doctor, but there he was, examining a newborn exposed to the virus in the womb. The infected mother had given birth just hours earlier. The hospital had alerted Dowse to the case before delivery, and he’d braced himself for the worst.
