The Pulse coupled neural network(PCNN)has been widely used in digital image processing, but the automatic parameters determination is still a difficult aspect, which becomes the focus of PCNN research. In this paper, by the classical solution to difference equations and the time-domain analysis of PCNN model, we provide the expressions of the firing time and the firing period of neurons, and reveal the "mathematics firing" phenomenon of PCNN. Based on this, we propose a new method of automatic parameters determination based on both eliminating the "mathematics firing" and getting the highest efficiency of PCNN. We also present an edge detection model on the basis of image segmentation of PCNN and a method to determine automatically the parameters of the model. Experimental results prove the validity and efficiency of our proposed algorithm for the segmentation and the edge detection of the test images.

Traditional image segmentation algorithms exhibit weak performance for plant cells which have complex structure. On the other hand, pulse-coupled neural network (PCNN) based on Eckhorn’s model of the cat visual cortex should be suitable to the segmentation of plant cell image. But the present theories cannot explain the relationship between the parameters of PCNN mathematical model and the effect of segmentation. Satisfactory results usually require time-consuming selection of experimental parameters. Mean-while, in a proper, selected parametric model, the number of iteration determines the segmented effect evaluated by visual judgment, which decreases the efficiency of image segmentation. To avoid these flaws, this note proposes a new PCNN algorithm for automatically segmenting plant embryonic cell image based on the maximum entropy principle. The algorithm produces a desirable result. In addition, a model with proper parameters can automatically determine the number of iteration, avoid visual judgment,

The logical sequence of China＇s state governance is ＂governing party--consultative conferences--people＇s congresses--the people.＂ The ＂governing party--consultative conferences＂ link in the chain involves political consultation through people＇s consultative conferences. The ＂governing party--consultative conferences--people＇s congresses＂ link involves a process of obtaining legitimacy for the Party＇s views based on political consultations which are then translated into the national will by the system of people＇s congresses. The ＂people＇s congresses--the people＂ link involves the two-pronged logic of elections and governing the country according to law. The ＂governing party--the people＂ link is an illustration of the party＇s mass line, which essentially involves social consultation. Consultative democracy usually includes the political consultation in the ＂governing party---consultative conferences＂ link and the social consultation in the ＂governing party-- the people＂ link in the chain, both of which are connected through the system of people＇s congresses. This logically determines the inner relations between the Party＇s leadership, consultative democracy and the people＇s congress form of representative democracy and shapes the institutionalization of consultative democracy. That is, in the process of democratic decision-making, a circular system consisting of ＂political consultation-- legislative consultation--social consultation＂ is created to guide development of the actual system.

Under the guidance of “technical value theory” taking both the natural and social attributes of technique into consideration, the fault in indirect infringements of copyrights by video sharing websites includes two forms:“intention” and “negligence”. As an objective criterion of negligence identification, the duty of care, is the natural extension of the security obligation in cyberspace;for a video sharing website, the foreseeable obligation of infringements is the main content of the duty of care;and it is highlighted that the degree of the duty of care hinges on different factors. For the form of liability, a video sharing website faces the difficulties of excessive costs in debt recovery after assuming the complementary liability, joint and several liability is thus alienated as an aggravating responsibility. However, according to the causative potency between the fault of a video sharing website and the infringement results, the several/shared liability can avoid the overburden to a video sharing website and distribute the risks of inadequate compensation based on the principle of fairness.

技术标准是全球基础设施的组成部分,技术标准许可是国际技术服务贸易的重要内容。技术标准是经标准化组织批准、非强制执行、可重复使用的通用技术方案规则和指南。在技术标准许可定价规则尚未统一的情况下,“国家”试图强化对技术标准实施活动的控制,表现为不同国家的司法机关在裁决标准必要专利许可费时适用不同的定价规则,而这些规则为国家力量的介入创造了空间。可比许可法是一种“非国家化”的技术标准许可定价规则,能集中反映消费者愿为标准必要专利支付的信息,注重参考在市场作用下业已形成的许可费水平,从而克服分摊式专利价值评估方法的缺陷。可比许可协议的识别、可比许可协议中许可费信息的披露以及复杂标准必要专利许可情形中隐性单向许可费率的解析,是可比许可法适用的关键。专利劫持和技术标准化价值等问题的澄清,有利于认定标准必要专利许可费的范围,打破对部分可比许可协议参考价值的质疑,确保可比许可法适用的稳定性。作为一项由市场主导的技术标准许可定价规则,可比许可法有助于定价规则的“非国家化”,在不同国家的司法机关间形成“规则共识”。

技术交互利用催生技术标准,技术标准许可贸易是全球多边贸易的重要内容。单边技术标准定价规则引发大量诉讼,使得以技术为生的市场主体疲于应对,无暇升级自身经济结构。技术标准的推行需要公平、合理、无歧视的多边贸易体制。作为技术标准的法律形态,标准必要专利许可费定价规则是多边技术贸易规则体系的核心内容。现有标准必要专利许可费定价规则表明,不同国家基于各自利益,在多边贸易体制外主动或被动制定单边规则,致使技术标准定价规则碎片化。以市场因素整合技术定价规则,重塑多边贸易体制的职能,实现多边贸易规则体系的现代化,增强多边贸易体制对全球价值链的适应性,是解决技术标准定价规则冲突的可行方案。倡导建立以市场为标准必要专利定价规则,使不同层级发展水平的国家能够在多边贸易体制下共享技术革命成果,以此推动全球均衡、包容、普惠发展,为构建人类命运共同体贡献中国智慧和中国方案。
