The first scientists to coin the term“trained immunity”were Mihai ***,Jessica Quintin,and Jos *** der Meer in a‘Perspective’article in 2011[2].With the publication of vast amounts of experimental data and follow-up reviews,the concept that the innate immune system can develop a memory function in parallel to the well-recognized adaptive memory,mediated by B and T lymphocytes,is largely accepted.

squamous papillomas are common lesions of the oral mucosa with a predilection for the mucosa of the hard and soft palate. As an oral lesion,it raises concern because of its clinical appearance,which may mimic exophytic carcinoma,verrucous carcinoma or condyloma acuminatum. Its pathogenesis is related to human papilloma virus but there is controversy regarding its viral origin. We present a case of squamous papilloma presenting as oral lesion along with a review of the literature.

GRACE卫星已于2002年3月17发射入轨。CRACE任务的实验目的旨在改进地球重力场模型的精度。CRACE任务由两颗几乎完全一样的孪生卫星来执行,两颗GRACE卫星运行在约500km高度的同一个准极轨道平面内,相距约200km。每颗卫星携带四种仪器:一台GPs接收机,一个K/Ka波段微波测距系统,一台星像机(这三种仪器均与一个公用处理器组装为一体),一个精密加速度计。GPs接收机能够跟踪最多14颗GPs卫星,可获得的双频数据精度与精密测地型地面接收机相当。K/Ka波段微波测距系统能实现μm级的测距精度(有一个常值偏差)。加速度计的测量精度高达1mm/s^2。而星跟踪器的姿态测量精度为10″。GPs数据经处理后可用于:(1)复原地球的长波引力场;(2)消除星上振荡器长期漂移引起的误差;(3)使2个GRACE卫星的K/Ka波段测量的定时精度校准到优于0.1ns。加速度计的标度因子和偏值参数是综合利用GPs数据和加速度计误差模型确定的。本文着重介绍利用GPs实现的这些定时和标定功能,而不讨论地球重力场的恢复问题。当然,GPs的定时功能与精确定轨(POD)密切相关。三轴的定轨精度均优于2cm。本文发表了GRACE的验证结果,包括GPs残差,轨道重叠,K/Ka波段测距以及卫星激光测距(sLR)的结果。为确定轨道参数和时钟参数,所有GPs数据的处理都是利用一个数据驱动的自动化系统完成的,该处理系统是专门为装备GPs接收机的卫星星座设计的。
