Besides, this new algorithm behaves faster convergence speed based on the analysis of equalizers’ working rules, which is more suitable to implement communications in dif-ferent unknown channels. Corresponding results and conclusions are validated by simulations and spot experiments.展开更多
间变型弥漫大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)是一种罕见的非特指型DLBCL,组织形态学常为窦性或者弥漫生长。该文报道1例,其左侧腋窝淋巴结具有大量多形性的中心母细胞样伴间变特征的细胞和HRS样细胞呈结节状或滤泡...间变型弥漫大B细胞淋巴瘤(diffuse large B-cell lymphoma,DLBCL)是一种罕见的非特指型DLBCL,组织形态学常为窦性或者弥漫生长。该文报道1例,其左侧腋窝淋巴结具有大量多形性的中心母细胞样伴间变特征的细胞和HRS样细胞呈结节状或滤泡生发中心样生长,符合DLBCL,非特殊类型,间变型。结合相关文献探讨其临床病理学及分子遗传学特征,以提高临床和病理医师对该肿瘤的认识。展开更多
