Today's somewhat disjointed approach to discipline-specific computing and generic computer literacy does not accurately mirror the knowledge, skills and abilities needed by the engineer of the future global workplace. Computing in the workplace is pervasive and involves many complex tools, many approaches to problem solving, strategic decision making and synthesis. Knowledge, comprehension and application are no longer enough for one to be labeled highly competent in computing. A successful engineer will need a mastery of computing applicable to the higher level cognitive skills of analysis, synthesis and evaluation, as well. To prepare students for pervasive, advanced computing in the workplace, we must begin to think in terms of pervasive, advanced computing in their education. This premise served as the basis for a project funded by the National science Foundation CISE Pathways to Revitalized Undergraduate Computing Education (CPATH) initiative in 2007. The project is being carried out by the authors comprised of a multidisciplinary team of faculty from six departments in the College of engineering and one from the College of Education at NC State University. The project has two overarching goals: (1) create a computational thinking thread in the engineering curriculum that spans from the freshman to senior years and bridges the divide between freshman year computing and computing in upper-level classes, and (2) enable students to take computing competency to the next level, where they are able to perform high-level computing tasks within the context of a discipline. The first phase of the project entails the establishment of an academe-industry community in which stakeholders from a broad range of disciplines will convene to discuss the challenges and opportunities inherent in transforming the undergraduate computing education, and to identify and implement creative strategies to do so. The "Computing Across Curricula" (CAC) community includes involvement from a

IEEE International Conference on Micro Electro Mechanical Systems

A thermally actuated organic display device using UV-sensitive polydiacetylene (PDA)-polyvinyl alcohol (PVA) composite film with self aligned patterns is presented. A novel technique that patterns UV-sensitive organic films on a transparent substrate using a chip-embedded photomask is demonstrated. In contrast to related works regarding PDA and its composites, the current investigation represents the first attempt to realize a PDA derivative film for a thermal-display. Micro-pixels ranging from 200 mum to 700 mum size were fabricated on a glass substrate. The transition tones of the blue, red and yellow micro-pixels were successfully tuned with embedded micro-heaters under the PDA-PVA layer using both low-temperature (75degC) and high-temperature (180degC) activation processes. The retention time was measured and found to be less than a few hundred milliseconds.

We immobilized the probe DNA oligonucleotides onto single wall carbon nanotube(SWNT) films and hybridized target DNA oligonucleotides with the complementary or non-complementary bases, in which SWNT films with a wide range of conductivities were prepared by vacuum filtration methods. Single strand DNA oligonucleotides were covalently attached to prepatterned films through amide bond formation using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride. Sensing ability of the DNA hybridization was demonstrated by investigating a change of response to linked DNA and its complementarity. We show that resultant DNA-attached CNT multilayer films are shown to exhibit good specificity for their potential use in biosensors. © 2007 CBMS.

In this paper, we present the electrochemically programmed release of immobilized IgG protein molecules that have been attached to gold coated surfaces via a thiol-gold linkage. Fluorescence microscopy has been used to image the release of fluorescently tagged IgGs in phosphate buffered saline. In this technique, the reductive desorption of self-assembled monolayers is employed for the release of proteins, which are immobilized on the surface either by non-covalent or covalent interactions. The voltage applied for the release of proteins is in a range of -1.5V to -60V. © 2007 Materials Research Society.

Cell robustness and complexity have been recognized as unique features of biological systems. This is attributable to the existence of multiple (or redundant) metabolic pathways and the concomitant multiple flux distributions, with each pathway leading to a single phenotype. Moreover, the multiple pathways may result in a variety of products or byproducts under different environmental conditions, e.g., substrate concentration, PH, and temperature. Appropriately controlling environmental or genetic conditions renders it possible to maximize the rate of substrate conversion and the production of a desired product or products by circumventing the occurrence of the secondary reactions yielding undesirable intermediates and byproducts. As such, we would enable us to devise or design biochemical manufacturing processes with enhanced energy efficiency and robustness;the resultant processes would be capable of increasing the rates of production, thereby lowering their costs. Proposed herein is an effective approach for exploring metabolic pathways, which algorithmically synthesizes all the candidate pathways by a rigorous graph-theoretic method based on P-graphs (process graphs).

We report a non-volatile, write-once-read-many times (WORM) memory device based on a simple organic-inorganic heterojunction. The organic-based hybrid used is 9, 9-dihexylfluorene and Eu-complexed benzoate (PF6Eu (DBM)), which contains both electron-donor (9, 9-dihexylfluorene) and electron-acceptor (europium complex) groups. The inorganic n-type silicon substrate is used as the bottom electrode, while the Al is used as the top electrode. Under current-voltage testing, the device is able to switch from one initial non-conducting state (OFF) to a conducting state (ON) once a threshold voltage is reached under the first positive sweep. The "OFF" state is not recoverable with subsequent negative sweep after the device is turned "ON". The ON/OFF current ratio is around 4×104. Diode rectifying characteristics is also observed for the tumed-on device with a current ratio of 7×104, which is essential to address one memory cell in large passive matrix circuits. Reliability test is carried out and the device is able to sustain its "ON" state for at least 12 hours without any external bias. © 2006 Materials Research Society.
