  • 简介:都市化的过程被人的常规运动形成。它在一个城市里产出不同功能的地区,例如居住地区和商业地区。因而,在那里存在在人的活动性模式和城市之间的一个靠近的连接是地区。然而,收集能精确捕获在个人的运动和地区性的功能之间的内在的关系的大规模社会宽的数据不是容易的。因此,我们为理解人的活动性的基本模式的知识仍然是有限的。以便在一个城市里发现不同区域的功能,我们建议一种亲密关系在这份报纸基于方法。亲密关系是为在一个复杂网络测量二个连接节点的关联的一个最近介绍的度量标准。建议模型由经由相对的熵测量用户的到达/离开分发组织不同功能的地区。除了这,我们也由拿核密度评价(KDE)识别每个功能的地区的紧张方法。最后,一些实验被进行与大规模真实数据集评估我们的方法,它从一个月的一个时期由300万个蜂窝电话用户的记录组成。我们在活动性模式和地区性的函数之间的相互作用上的调查结果能高效地捕获城市动力学并且为城市的规划者提供珍贵引用。

  • 简介:C类型natriuretic肽(CNP)是调停的本地规章的因素的一种最新发现的类型它通过specic的生物效果,膜界限natriuretic肽receptor-B(NPR-B)。最近的研究证实了CNP是仔细与男繁殖功能有关。这研究的目的是通过不同方法在人的呼喊的精子决定CNP/NPR-B的分发,然后在精子功能invitro上评估CNP的影响(例如immunolocalization,实时聚合酶链反应和西方的污点),例如活动性和acrosome反应。人的精液样品从同意的施主被收集为normozoospermia满足了世界健康组织的标准。我们的结果证明CNP的specic受体NPR-B在头和精子的前端尾巴的膜的acrosomal区域是局部性的,并且没有在人的精子的CNP的信号。与控制相比,CNP能在精子活动性和acrosome反应导致signicant剂量依赖者增加。在摘要,CNP/NPR-B能影响精子活动性和acrosome反应,因此调整男性的繁殖功能。CNP可以是在调整精子功能的一个新关键因素。
