Multi-modal Approach for Affective Computing
Throughout the past decade, many studies have classified human emotions using
only a single sensing modality such as face video, electroencephalogram (EEG),
electrocardiogram (ECG), galvanic skin response (GSR), etc. The results of
these studies are constrained by the limitations of these modalities such as
the absence of physiological biomarkers in the face-video analysis, poor
spatial resolution in EEG, poor temporal resolution of the GSR etc. Scant
research has been conducted to compare the merits of these modalities and
understand how to best use them individually and jointly. Using multi-modal
AMIGOS dataset, this study compares the performance of human emotion
classification using multiple computational approaches applied to face videos
and various bio-sensing modalities. Using a novel method for compensating
physiological baseline we show an increase in the classification accuracy of
various approaches that we use. Finally, we present a multi-modal
emotion-classification approach in the domain of affective computing research.Comment: Published in IEEE 40th International Engineering in Medicine and

Biomimetic and bioinspired silica : recent developments and applications
In a previous review of biological and bioinspired silica formation (S. V. Patwardhan et al., Chem. Commun., 2005, 1113 [ref. 1]), we have identified and discussed the roles that organic molecules (additives) play in silica formation in vitro. Tremendous progress has been made in this field since and this review attempts to capture, with selected examples from the literature, the key advances in synthesising and controlling properties of silica-based materials using bioinspired approaches, i.e. conditions of near-neutral pH, all aqueous environments and room temperature. One important reason to investigate biosilicifying systems is to be able to develop novel materials and/or technologies suitable for a wide range of applications. Therefore, this review will also focus on applications arising from research on biological and bioinspired silica. A range of applications such as in the areas of sensors, coatings, hybrid materials, catalysis and biocatalysis and drug delivery have started appearing. Furthermore, scale-up of this technology suitable for large-scale manufacturing has proven the potential of biologically inspired synthesis
From Pronoun to Identity: Tracing the History of the Word Otaku
Words are vessels of power; the power to convey meaning. Words can give shape to the identity of a group, and the same word can stereotype one for generations. This research paper is about one such word – ‘Otaku’. The aim of this research paper is to trace the history of the term ‘otaku’, and understand how it evolved from a second person
pronoun to a term that identifies an entire subcultur
