目的 :评估未经治疗的无冠状动脉疾病的家族性高胆固醇血症所有原因的死亡率。设计 :家系死亡率研究。背景 :荷兰的一个大家系 ,其宗亲源自 19世纪一对夫妇。先证者 :家族中所有超过 2 0岁且有 5 0 %可能性携带家族性高胆固醇血症突变基因者。主要结果测定指标 :各种原因的死亡率。结果 :分析自 6 95 0人年的 2 5 0人中共死亡的70人。突变基因携带者的死亡率在 19世纪和 2 0世纪早期并未升高 ,1915年后开始升高 ,1935～196 4年达到高峰 (标准化死亡率比 1 78,95 %可信区间 1 13～ 2 76 ,P =0 0 0 3) ,以后下降。家系的两大分支间死亡率有显著性差异 (相对危险性3 2 6 ,95 %可信区间 1 74～ 6 11;P =0 0 0 1)。结论 :家族性高胆固醇血症患者间的死亡危险性差异显著。这种时间上及家系的不同分支间的巨大差异表明环境因素与基因有强大的相互作用。有必要进一步研究以识别那些极高危并需早期和强力预防措施的家族性高胆固醇血症患者。

No consensus was found for all other proposed elements that may be included in a general *** There is no universally accepted definition of CAL in the Netherlands and China. Diagnosis of CAL based on clinical manifestations remains a point of discussion in both countries. Dutch surgeons are more likely to report ‘subclinical' leaks as CAL,which partly explains the higher reported Dutch CAL rates.

本文主要报道一组家兔的骨组织对骨水泥造影剂硫酸钡的生物反应。于不同时间对股骨标本做组织学和显微X线照像检查。结果表明，植入含有硫酸钡骨水泥的一侧股骨，其骨组织原发性损伤与弥散性坏死较另一侧无硫酸钡对照组严重。同时，新生骨形成量较对照组少。推测硫酸钡可能是造成这种生物反应差别的主要原因。

Investment of information technology (IT) in the government sector in Indonesia continues to increase every year. However, this increase has not been followed by good governance due to the lack of attention to good IT management. Measurement of IT governance is therefore required as a basis for the continuous improvement of the IT services to government agencies. This study is aimed at producing an application to measure the maturity level of IT governance in government institutions, thus facilitating the process of improvement of IT services. The application developed is based on COBIT 4.1 framework and the design used is Unified Modeling Language. Through stages of information system development, this research results in an application for measuring the maturity level of IT governance that can be used by government agencies in assessing existing IT governance.

The pricing of moving window Asian option with an early exercise feature is considered a challenging problem in option pricing. The computational challenge lies in the unknown optimal exercise strategy and in the high dimensionality required for approximating the early exercise boundary. We use sparse grid basis functions in the Least Squares Monte Carlo approach to solve this “curse of dimensionality” problem. The resulting algorithm provides a general and convergent method for pricing moving window Asian options. The sparse grid technique presented in this paper can be generalized to pricing other high-dimensional, early-exercisable derivatives.

A multistandard software-defined radio base station must perform non-uniform channelization of multiplexed frequency bands. Non-uniform channelization accounts for a significant portion of the digital signal processing workload in the base station receiver and can be difficult to realize in a physical implementation. In non-uniform channelization methods based on generalized DFT filter banks, large prototype filter orders are a significant issue for implementation. In this paper, a multistage filter design is applied to two different non-uniform generalized DFT-based channelizers in order to reduce their filter orders. To evaluate the approach, a TETRA and TEDS base station is used. Experimental results show that the new multistage design reduces both the number of coefficients and operations and leads to a more feasible design and practical physical implementation.

2021年“21·7”河南特大暴雨打破我国大陆小时气象观测纪录,该极端天气事件位列2021年中国十大天气气候事件第2位。已有研究使用气象地面站雨量观测资料对此次过程进行雨情分析和极值统计,但降水时空分布不均匀,单一来源资料存在不确定性。通过对比气象站和水文站雨量资料,分析两套业务观测系统记录“21·7”河南特大暴雨过程的异同,发现气象站和水文站雨量在时间和空间分布上具有很好的一致性,两者不同等级的累积降雨落区、逐日和逐时降雨演变趋势均一致性强,但累积雨量和雨强极值的空间分布和数值存在差异,两套资料在暴雨中心(过程雨量大于600 mm)的系统性偏差小于1%。气象站和水文站的融合资料呈现比单一资料更细致的降雨分布、更全面的演变特征。此外,基于融合资料发现累积雨量排名前3位的城市(郑州、鹤壁、新乡)均具有累积雨量大、小时雨强极强、强降雨集中、雨强突然增长的特征,鹤壁和新乡最强降雨时段分别比郑州晚26 h和28 h。
