Keywords: Cooperative/collaborative learning Interactive learning environments Authoring tools and methods a b s t r a c t A limitation of current Web-based collaborative learning is the restricted ability of students to create and share individual annotations with annotated documents. Applying Web 2.0 collaborative annotation systems and analyzing(More)
The Internet of Things (IoT) offers the promise of integrating the digital world of the Internet with the physical world in which we live. But realizing this promise necessitates a systematic approach to integrating the sensors, actuators, and information on which they operate into the Internet we know today. This paper reports the design and development of(More)
This paper presents a social network-based peer-to-peer search service for identifying right collaborators in the context of Web 2.0. We present a three-layer hierarchical social network, in which we identify two important relationship ties - knowledge relationship tie and social relationship tie. These relationship ties are metric used to measure the(More)
Myelin transcription factor 1 (Myt1) is one of the three vertebrate C2HC-type zinc finger transcription factors that include Myt1 (Nzf1), Myt1L (Png1), and Myt3 (Nzf3, St18). All three paralogs are widely expressed in developing neuronal cells. Yet their function for mammalian development has not been investigated directly. Here we report that only Myt1 is(More)
As Web services become more and more popular, how to manage multimedia Web services that can be composed as value-added service solutions remains challenging. This paper presents a service-oriented multimedia componentization model to support Quality of Service (QoS)-centered, device-independent multimedia Web services, which seamlessly incorporates(More)
Knowledge sharing in computer supported collaborative learning (CSCL) requires intensive social interactions among participants, typically in the form of annotations. An annotation refers to an explicit expression of knowledge that is attached to a document to reveal the conceptual meanings of an annotator's implicit thoughts. In this research, we develop a(More)
— Triggered by the ever growing demand of wireless data rate, modern cellular network is in the middle of a paradigm shift. By deploying small cells underlaying current macrocells, a heterogeneous network (HetNet) architecture is formed with great potentials to improve system capacity and reduce overall energy consumption in the mean time. However, such(More)
Mononuclear phagocytes are a population of multi-phenotypic cells and have dual roles in brain destruction/reconstruction. The phenotype-specific roles of microglia/macrophages in traumatic brain injury (TBI) are, however, poorly characterized. In the present study, TBI was induced in mice by a controlled cortical impact (CCI) and animals were killed at 1(More)
