Unsupervised Multiway Data Analysis: A Literature Survey

Abstract: Two-way arrays or matrices are often not enough to represent all the information in the data and standard two-way analysis techniques commonly applied on matrices may fail to find the underlying structures in multi-modal datasets. Multiway data analysis has recently become popular as an exploratory analysis tool in discovering the structures in higher-order datasets, where data have more than two modes. We provide a review of significant contributions in the literature on multiway models, algorithms as well as their applications in diverse disciplines including chemometrics, neuroscience, social network analysis, text mining and computer vision.

The Role of Incubators in the Entrepreneurial Process

Abstract: We outline a model that improves our understanding of the role of incubators in the entrepreneurial process. Specifically, we focus on the impact of the services offered, namely infrastructure, coaching and networks, on the graduation rates of the respective incubators' tenants. The model is tested among three different types of incubators, for-profit, non-profit, university-based incubators. Based on our qualitative findings, we conclude that our initial model is ineffective, in the sense that it cannot fully explain the role of the incubators in facilitating entrepreneurship. Interviews with directors of incubator centers were also carried out simultaneously. Further analysis of the results along with interview responses from incubator directors, led us to propose a more comprehensive model to explain how incubators affect the entrepreneurial process.

SLPA: Uncovering Overlapping Communities in Social Networks via a Speaker-Listener Interaction Dynamic Process

Abstract: Overlap is one of the characteristics of social networks, in which a person may belong to more than one social group. For this reason, discovering overlapping structures is necessary for realistic social analysis. In this paper, we present a novel, general framework to detect and analyze both individual overlapping nodes and entire communities. In this framework, nodes exchange labels according to dynamic interaction rules. A specific implementation called Speaker-listener Label Propagation Algorithm (SLPA) demonstrates an excellent performance in identifying both overlapping nodes and overlapping communities with different degrees of diversity.

Fabrication of high-aspect ratio, micro-fluidic channels and tunnels using femtosecond laser pulses and chemical etching

Abstract: We present novel results obtained in the fabrication of high-aspect ratio micro-fluidic microstructures chemically etched from fused silica substrates locally exposed to femtosecond laser radiation. A volume sampling method to generate three-dimensional patterns is proposed and a systematic SEM-based analysis of the microstructure is presented. The results obtained gives new insights toward a better understanding of the femtosecond laser interaction with fused silica glass (a-SiO2).
