Industry stakeholders and Internet experts generally agree that networks using Internet Protocol version 6 (IPv6), an Internet
communications standard which is being promoted strongly by many parties, would be technically superior to today’s networks,
which are largely based on IPv4. The improvements designed for IPv6 could provide numerous benefits to Internet users, network
administrators, and applications developers; among these potential benefits are cost reductions due to improved security and
increased efficiency, improvements to existing products and services, and innovations leading to new products and services.
However, there is wide disagreement about the characteristics and timing of benefits associated with IPv6, and the costs associated
with the transition could be substantial. In this paper, we will discuss the likely costs of a transition to IPv6 for the
major stakeholders and the potential benefits. Subsequently, we will introduce the cost impact of an accelerated adoption
case and discuss potential ways in which the government could become involved in the process.
This paper is based on a broader study funded by the National Telecommunications and Information Administration (NTIA) and
National Institute of Standards and Technology (NIST). We wish to thank Greg Tassey, Fred Lee, Tim Sloan, B. Keith Fulton,
John Streck, and Baran Erkel for comments and suggestions on earlier versions of this paper. 相似文献

[HT5K]目的:观察益化清解方对2型糖尿病(T2DM)大鼠炎性分子网络调控的影响。方法:复制T2DM大鼠模型,治疗组用益化清解方中药灌胃,并与模型组、二甲双胍组及正常组作对照。分别在给药前和给药第15,30天检测T2DM大鼠的肿瘤坏死因子 α(TNF α)、白介素6(IL 6)、高敏C 反应蛋白(hsCRP)、脂联素(Adiponectin,Adp)、瘦素(leptin)水平,探讨其变化与空腹血糖(FBG)、血清胰岛素(FINS)及胰岛素敏感性指数(ISI)的关系;并检测各组大鼠脂肪组织脂联素及骨骼肌组织脂联素受体R1 Mrna表达水平,探讨Adp、Adp受体与这些因素之间的关系。结果:益化清解方能显著降低T2DM大鼠血糖、血脂、C反应蛋白等水平,并提高胰岛素敏感性,改善糖尿病大鼠的脂肪组织Adp Mrna表达水平。结论:益化清解方对糖、脂双调节的作用可能是通过增加胰岛素敏感性而实现的,其与改善糖尿病大鼠的脂肪组织Adp Mrna表达相关. 相似文献

细胞因子(IL-6、TNF-α)在损伤时间中原位杂交法研究 总被引:2,自引:1,他引:1
采用原位杂交法,研究大鼠切削皮肤中细胞团子IL-6、TNF-αmRNA表达量,旨在探讨IL-6、TNF-α推断法医损伤时间的应用价值以及其在损伤生活反应中的分子机制。研究结果表明,根据大鼠损伤皮肤中TNF-αmRNA表达量能够区别生前伤与死后伤,并可以利用TNF-αmRNA表达量改变准确区别60min内和60min后损伤时间,但IL-6mRNA表达量在研究组内均未见阳性反应,不能推断损伤时间。 相似文献

目的探讨颅内出血患者血清IL-6、TNF-α的水平变化及在法医学的临床意义。方法采用酶联免疫吸附法(ELISA)对颅内出血患者住院后不同时间段血清IL-6、TNF-α水平进行检测,并与正常对照组的健康受试者进行比较分析。结果研究组重型与轻型患者后第1、3、5、7天血清IL-6、TNF-α水平较正常对照组明显增加,重型患者入院第5、7天的血清IL-6、TNF-α较轻型患者明显增加,差异有统计学意义(P0.05);根据患者最后结果(死亡组和存活组),发现死亡组随着时间延长,在第5、7天时IL-6、TNF-α水平显著高于存活组(P0.05)。此外,血清IL-6和TNF-α水平呈正性显著相关(r=0.721,P0.05)。结论检测颅内出血患者血清IL-6、TNF-α水平对观察其病情变化有重要意义,可作为法医学鉴定的辅助手段。 相似文献

Estimating the number of contributors to mixed STR profiles can be complex. This study describes the nC-tool to assist DNA expert in this process. The nC-tool is based on the total allele count for PowerPlex® Fusion 6C profiles and showed improved performance when compared to the maximum allele count approach. 相似文献

On 26 July 2017, the Grand Chamber of the European Court of Justice rendered its seminal Opinion 1/15 about the agreement on Passenger Name Record data between the EU and Canada. The Grand Chamber considered that the decision of the Council about the conclusion, on behalf of the Union, of the agreement between the EU and Canada about the transfer and processing of PNR data must be based jointly on Article 16(2) about the protection of personal data and Article 87(2)(a) about police co-operation among member states in criminal matters, but not on Article 82(1)(d) about judicial co-operation in criminal matters in the EU of the Treaty on the Functioning of the EU. The Grand Chamber also considered that the agreement is incompatible with Article 7 on the right to respect for private life, Article 8 on the right to the protection of personal data, Article 21 on non-discrimination and Article 52(1) on the principle of proportionality of the Charter of Fundamental Rights of the EU since it does not preclude the transfer, use and retention of sensitive data. In addition to the requirement to exclude such data, the Grand Chamber listed seven requirements that the agreement must include, specify, limit or guarantee to be compatible with the Charter.The opinion of the Grand Chamber has far-reaching implications for the agreement on PNR data between the EU and Canada. It has also far-reaching implications for international agreements on PNR data between the EU and other third states. Last, it has far-reaching implications for Directive 681 of 27 April 2016 on PNR data. 相似文献

In recent years, students in police academies and higher education institutions around the world have worked together to analyse cold cases including long-term missing persons cases in collaboration with investigators and prosecutors. In 2020, three European organisations, the Police Expert Network on Missing Persons (PEN-MP), AMBER Alert Europe and Locate International, succeeded in connecting these educational organisations enabling them to work collectively on cases and conduct cold case analyses (CCA) across international borders. The International Cold Case Analysis Project (ICCAP) learning objectives were to 1) collect the necessary information about the victim, 2) reconstruct the crime, and 3) investigate trace control.In a learning objective-based evaluation using Computer-Assisted Web Interviewing, 76 participating students from the German and International ICCAP teams were asked to complete a pre- and post-review questionnaire to self-assess their personal competence development. Participants reported significant increases in competence in all evaluated areas, thus demonstrating that authentic and relevant collaborations can enrich the learning environment, promote the use of professional skills, and provide significant knowledge exchange opportunities between academia and industry.Drawing on case studies of cold case missing persons' investigations and unidentified found remains, this article shares how university academics, students and community volunteers can work together nationally and internationally to find out what has happened to missing people and how we can more effectively identify the previously unidentified. In so doing, we share the expertise required to progress these cold cases and provide recommendations to support other institutions and organisations in adopting this innovative approach. 相似文献
