摘要：An abstraction and an investigation to the worth of dendritic cells (DCs) ability to collect, process and present antigens are presented. Computationally, this ability is shown to provide a feature reduction mechanism that could be used to reduce the complexity of a search space, a mechanism for development of highly specialized detector sets as well as a selective mechanism used in directing subsets of detectors to be activated when certain danger signals are present. It is shown that DCs, primed by different danger signals, provide a basis for different anomaly detection pathways. Different antigen-peptides are developed based on different danger signals present, and these peptides are presented to different adaptive layer detectors that correspond to the given danger signal. Experiments are then undertaken that compare current approaches, where a full antigen structure and the whole repertoire of detectors are used, with the proposed approach. Experiment results indicate that such an approach is feasible and can help reduce the complexity of the problem by significant levels. It also improves the efficiency of the system, given that only a subset of detectors are involved during the detection process. Having several different sets of detectors increases the robustness of the resulting system. Detectors developed based on peptides are also highly discriminative, which reduces the false positives rates, making the approach feasible for a real time environment.

摘要：弹簧圈栓塞最初被设计并经美国食品药品监督管理局批准用于治疗显微外科手术夹闭风险高的脑动脉瘤，但目前该方法越来越被认为是颅内动脉瘤的一线治疗方法。动脉瘤血管内治疗技术已有长足进步，新器材的研发使得以前因血管解剖结构复杂而无法填塞的动脉瘤也得以治疗，从而扩大了血管内治疗的适应证。而且，血管内弹簧圈栓塞已成为当前动脉瘤血管内治疗的主流方法；医学文献证明，在特定患者人群中，弹簧圈栓塞的转归优于外科手术夹闭。最近的一份美国心脏协会（AmericanHeartAssociation，AHA）科学声明指出，对于适合治疗的脑动脉瘤，不论是血管内栓塞还是显微外科手术夹闭，均为破裂动脉瘤I级推荐治疗方法和未破裂动脉瘤的11a级推荐治疗方法。在这两组患者中，治疗利大于弊。一个在血管显微神经外科、神经重症监护和介入神经外科方面有着丰富经验的多学科团队最有利于对颅内动脉瘤的处理实施最佳的技术。神经血管联合写作组此前已发表过一份联合声明，提出了有关脑血管介入治疗的培训和认证的推荐意见。

摘要：丹麦著名建筑师事务所BIG（Bjarke Ingels Group）最近公布了哥本哈根动物园熊猫馆的设计方案。新的熊猫馆呈环形状分布，像一个巨大的太极符号，由多个交叉的步道和周边现有的设施组成。身处场馆中，人类就像是熊猫请来的客人，并没有与这种珍稀动物产生从遥远国土被邀请而来的疏离感。栖息地为它们提供了最自由和最自然的生活环境，以及理想的交配条件，这也是解决熊猫濒临灭绝问题的最主要的挑战之一。
