Organosilane deposition for microfluidic applications

Treatment of surfaces to change the interaction of fluids with them is a critical step in constructing useful microfluidics devices, especially those used in biological applications. Silanization, the generic term applied to the formation of organosilane monolayers on substrates, is both widely reported in the literature and troublesome in actual application for the uninitiated. These monolayers can be subsequently modified to produce a surface of a specific functionality. Here various organosilane deposition protocols and some application notes are provided as a basis for the novice reader to construct their own silanization procedures, and as a practical resource to a broader range of techniques even for the experienced user.     

A hypermedia system for teaching database design task

The number of commercial object-oriented database systems and object-oriented interfaces to traditional database systems is increasing. To facilitate the process of object-oriented data modelling (OODM) for experts and end-users, a hypermedia system is designed that is able to teach and guide users in performing OODM. The system supports the full range of modelling activities, from the identification of a class and its properties, to the relationships among classes. It provides other important functions, such as error checking of the model, graphical interface and the provision of hypermedia contextual explanations. Hypermedia are effectively used in the system so that the users can learn OODM effectively, as well as perform OODM correctly and quickly. The system has been empirically evaluated to gauge its effectiveness and ease of use. The evaluation suggests that the system will be useful for a OODM training or teaching course, and it can also be an effective computer-based learning tool for selflearning

风险投资与天使投资对创业企业创新活动的影响

创业企业的创新活动对其生存和发展具有重要影响,风险投资和天使投资作为创业初期两种重要的权益资本来源,对其创业创新活动有重要的影响,但其影响的机理和效果却存在一定的差异.本文利用美国考夫曼创业企业基金会的考夫曼企业调查(Kauffman firm survey,KFS)数据进行了实证分析,指出具有风险投资融资背景的创业企业更关注企业长期竞争力的构建与维持,注重创新活动的投入与质量,从而在R&D费用投入强度方面比天使投资参与的创业企业要高;具有天使投资的创业企业则更看重短期创新活动的产出效果,从而在专利申请量上略高于风险投资参与的创业企业.     

Towards precision medicine: from quantitative imaging to radiomics

Radiology (imaging) and imaging-guided interventions, which provide multi-parametric morphologic and functional information, are playing an increasingly significant role in precision medicine. Radiologists are trained to understand the imaging phenotypes, transcribe those observations (phenotypes) to correlate with underlying diseases and to characterize the images. However, in order to understand and characterize the molecular phenotype (to obtain genomic information) of solid heterogeneous tumours, the advanced sequencing of those tissues using biopsy is required. Thus, radiologists image the tissues from various views and angles in order to have the complete image phenotypes, thereby acquiring a huge amount of data. Deriving meaningful details from all these radiological data becomes challenging and raises the big data issues. Therefore, interest in the application of radiomics has been growing in recent years as it has the potential to provide significant interpretive and predictive information for decision support. Radiomics is a combination of conventional computer-aided diagnosis, deep learning methods, and human skills, and thus can be used for quantitative characterization of tumour phenotypes. This paper discusses the overview of radiomics workflow, the results of various radiomics-based studies conducted using various radiological images such as computed tomography (CT), magnetic resonance imaging (MRI), and positron-emission tomography (PET), the challenges we are facing, and the potential contribution of radiomics towards precision medicine.     

From PSAs to reel communities: exploring the sounds and silences of urban youth mobilizing digital media production

ABSTRACT

Amplified by a global political climate of fear, oppression, and increased nationalism, this article examines how U.S. secondary students in a digital media elective course used multimodal composition, and video production in particular, as a nexus of ‘participatory politics.’ By partnering theories of multiliterate expression with youth civic engagement, it offers new understandings into how urban youth use digital media production to leverage school-based social action. Refracted through a mediated discourse analysis lens, and with a particular focus on sound as a modal resource for design, findings suggest that youth used media production and semiotic sense-making to simultaneously enliven community action as well as shield students from personal histories of trauma. By engaging in the process of digital media production, as this article suggests, students cultivated new core practices of civic interaction and local engagement by amplifying injustice.
