work Proximity to Jamming Governs Acoustic Attenuation in Damped Packings A grain-scale "Jammed-Network Scattering" framework that explains the long-standing linear frequency dependence of acoustic attenuation in fluid-saturated granular media, using particle-based simulations. Apple LLM Performance Tracker Which open-weight models actually run well on which Apple silicon, and through which engine — per CPU, memory and machine count, from M1 to M5 Ultra. Who's still in? Self-reported serving status of U.S. Naval Academy classmates — reported still in, out, and unreported shares of each class's documented commissions, plus pay grade, community, and post-service industry breakdowns. fun
