    Music generation stops chasing generic appeal: distilling a listening history into an aesthetic profile makes the same track fit the listener

    PAG-Agent distills a listener's favorite songs and contextual profile into an explicit Personal Aesthetic Profile that a planning model turns into generation instructions, raising target-user consistency by roughly 9 to 19 percent over direct conditioning on Personal-100.

    Remote sensing super-resolution stops feeding dense low-res maps: object slots lift PSNR by 2.03 dB over DiT4SR on UCMerced

    Remote sensing super-resolution previously injected low-resolution observations as dense spatial conditions into a diffusion Transformer, so small foreground objects were easily diluted by dominant backgrounds. MOSAIC organizes degraded observations into compact object-level and layout-level structural slots, fuses them across resolutions, and retrieves recurring structural priors from a shared prototype memory, then injects them into a frozen DiT4SR backbone through lightweight residual modulation. On UCMerced, AID and RSSCN7, PSNR is best at both scales, exceeding DiT4SR by 2.03 dB on UCMerced, 4.54 dB on AID and 1.49 dB on RSSCN7, with the lowest LPIPS on RSSCN7 and AID.

  3. Cathode lithium-rich compensators for next-generation lithium-ion batteries: classification framework, challenges, and synergistic prelithiation strategies

    This review addresses active lithium loss during the initial cycling and long-term operation of lithium-ion batteries by establishing a classification framework for cathode lithium-rich compensators (LRCs) based on lithium compensation mechanisms, covering binary, ternary, over-lithiated, sacrificial lithium salt, and sustained-release types; it systematically summarizes their working principles, typical charge compensation pathways, and practical performance, discusses key challenges including air instability, gas evolution, high delithiation voltage, and processing issues, highlights mitigation strategies involving nanoscale engineering, surface coating, defect and doping design, and electrolyte optimization, and further proposes a synergistic multimodal lithium-compensation strategy int
