Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

Guangtongxin yanjiu, 2018 白光发光二极管（LED）的发光模型是室内可见光定位系统设计的重要基础,发光模型参数不准确会严重影响可见光定位的精度。针对这一问题,文章提出了一种朗伯模型参数优化方法,该方法利用基于接收信号强度的可见光室内技术中朗伯模型参数对定位误差的影响,通过调整朗伯指数寻找最小测距误差,当测距误差最小时,所对应的朗伯指数与LED的真实朗伯指数最为接近。仿真了室内5m×5m×3m的场景,结果表明,朗伯模型参数优化方法能显著提高可见光室内定位精度,也验证了朗伯模型参数优化方法的可行性及有效性。
