Online visibility: EMBS gets e-savvy [Student Activities]

I came across an e-newsletter from the British Museum last week advertising free delivery when you spend more than ￡100 on British Museum sculptures and replicas. Inasmuch as my small flat in London could use a bust replica of an Egyptian noble woman or a Rosetta Stone coffee mug, it was the ending of the newsletter that caught my eye in particular. To help others find this newsletter, the British Museum has conveniently provided links to ten networking Web sites (some of which I have never heard of): Digg It!, Del.ico.us, Newsvine, Reddit, StumbleUpon, Facebook, Google, Twitter, Myspace, LinkedIn. The British Museum is e-savvy. I started to think about the IEEE and the IEEE Engineering in Medicine and Biology Society (EMBS), and I thought I would share some of our own proud e-achievements and current endeavors that we have come a long way over the past several years.     

Classification of normal and dysphagic swallows by acoustical means

This paper proposes a noninvasive, acoustic-based method to differentiate between individuals with and without dysphagia or swallowing dysfunction. Swallowing sound signals, both normal and abnormal (i.e., at risk of some degree of dysphagia) were recorded with accelerometers over the trachea. Segmentation based on waveform dimension trajectory (a distance-based technique) was developed to segment the nonstationary swallowing sound signals. Two characteristic sections emerged, Opening and Transmission, and 24 characteristic features were extracted and subsequently reduced via discriminant analysis. A discriminant algorithm was also employed for classification, with the system trained and tested using the leave-one-out approach. Overall, 350 signals were used from three bolus consistencies (semisolid, thick and thin liquids). A final screening algorithm correctly classified 13 of 15 control subjects and 11 of 11 subjects with some degree of dysphagia and/or neurological impairments. The proposed method has great potential to reduce the need for videofluoroscopic swallowing studies (the current gold standard method for swallowing assessment, which is invasive and nonportable) and to assist in the overall clinical assessment of swallowing sound signals.     

The dreaded question. . . [GOLD]

All good things must come to an end, including a thesis. After years of reading countless journal articles, scouring through textbooks, listening to hours of lectures, attending annual IEEE Engineering in Medicine and Biology Society (EMBS) conferences, meeting numerous clinicians, coding at all hours of the night, and dissecting draft after draft after written draft, there comes a time in every graduate student?s life when the thesis is ready for the print room. Engineering graduate students around the world spend years of their lives striving toward the goal of a finished thesis product, one which contributes novel ideas and techniques to the scientific community. However, upon reaching the pinnacle of their early careers, it is almost a certainty that every student will be faced with the dreaded question: "Now that you have finished your thesis, what's next?"     

DNA-directed synthesis of zinc oxide nanowires on carbon nanotube tips

This paper describes a class of three component hybrid nanowires templated by DNA directed self-assembly. Through the modification of carbon nanotube (CNT) termini with synthetic DNA oligonucleotides, gold nanoparticles are delivered, via DNA hybridization, to CNT tips that then serve as growth sites for zinc oxide (ZnO) nanowires. The structures we have generated using DNA templating represent an advance toward building higher order sequenced one dimensional nanostructures with rational control.
