The advent of the Internet inadvertently augmented the functioning and success of violent extremist organizations. Terrorist organizations like the Islamic State in Iraq and Syria (ISIS) use the Internet to project their message to a global audience. The majority of research and practice on web‐based terrorist propaganda uses human coders to classify ...

From demonstrative to definite and beyond: the case of nage in spoken Taiwan Mandarin
When demonstrative pronouns undergo grammaticalization, they have regularly been shown to evolve into definite or specific articles (Lehmann 2002, De Mulder & Carlier 2001). In a synchronic perspective, it has also been shown that for some languages, demonstrative determiners are not restricted to deictic or anaphoric functions, but may extend their ...

在学界,狭义相对论原理的建立过程仍有待进一步细化,以便学者们能够准确把握住狭义相对论的逻辑细节。狭义相对论原理的确立,本质上是爱因斯坦对经典力学内部不一致性的分析与批判,对\"同时的相对性\"的揭示是其整个论证的枢纽环节。在此过程中,爱因斯坦展现出了西方哲学主流的思维方式,这一思维方式以\"思想的前提批判\"为本质特征,为\"中国哲学 ...

Research of Opto-electronic Integrated Receiver in Industrial Control for POF Communication [PDF]
随着经济的飞速发展,传统的手工生产方式正逐步被自动化的生产方式取代。工人仅操作控制面板,将生产指令经传输媒介传达至自动化设备末端进行生产的方式是大势所趋。作为传输指令的载体,采用传统的铜线进行传输已无法确保数据完整性及工业精准度。符合“光进铜退”环保政策的新兴材料——塑料光纤(PlasticOpticalFiber,POF)因具有优异的电磁抗扰性和易接续、低成本的特性,日渐广泛的应用在工业控制、车载网络、音频数据传输等各种短距离通信领域。工业控制中,POF的使用可以隔离共模电压 ...
