  • Xia, Ling; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers, 2010-05)
    As in Si CMOS, the incorporation of mechanical strain offers the possibility of improving the performance of III-V field effect transistors (FETs). Quantifying its potential and providing fundamental understanding of the ...
  • Karumanchi, Sisir; Iagnemma, Karl; Scheding, Steve; Karumanchi, Sisir, B (Institute of Electrical and Electronics Engineers (IEEE), 2013-05)
    This paper addresses the problem of ensuring mobile robot motion safety when reacting to soft and hard hazards in a static environment. The work is aimed at off-road navigation for mobile ground robots where soft hazards ...
  • Chun, Byung-Gon; Curino, Carlo; Sears, Russell; Shraer, Alexander; Madden, Samuel R.; Ramakrishnan, Raghu (Association for Computing Machinery, 2012-06)
    Mobile application development is challenging for several reasons: intermittent and limited network connectivity, tight power constraints, server-side scalability concerns, and a number of fault-tolerance issues. Developers ...
  • Hackl, Martin; Nissenbaum, Jon (Springer-Verlag, 2011-10)
    This squib presents two puzzles related to an ambiguity found in for-infinitival relative clauses (FIRs). FIRs invariably receive a modal interpretation even in the absence of any overt modal verb. The modal interpretation ...
  • Murphy, E.; Ghisalberti, M.; Nepf, Heidi (American Geophysical Union, 2007-05)
    Vegetation is ubiquitous in rivers, estuaries, and wetlands, strongly influencing water conveyance and mass transport. The plant canopy affects mean and turbulent flow structure, and thus both advection and dispersion. ...
  • Zhang, Yong; Liu, Tao; Meyer, Clifford A; Eeckhoute, Jerome; Johnson, David S; Nussbaum, Chad; Myers, Richard M; Brown, Myles; Li, Wei; Liu, Xiaole S; Bernstein, Bradley E. (BioMed Central Ltd, 2008-09)
    We present Model-based Analysis of ChIP-Seq data, MACS, which analyzes data generated by short read sequencers such as Solexa's Genome Analyzer. MACS empirically models the shift size of ChIP-Seq tags, and uses it to improve ...
  • Heldt, Thomas; Verghese, George C. (Institute of Electrical and Electronics Engineers (IEEE), 2010-08)
    As a result of improved hospital information-technology infrastructure and declining costs of storage media, vast amounts of physiological waveform and trend data can now be continuously collected and archived from bedside ...
  • Mikaelian, Tsoline; Rhodes, Donna H.; Nightingale, Deborah J.; Hastings, Daniel E. (Institute of Electrical and Electronics Engineers, 2009-04)
    Uncertainties can be managed through real options that provide a decision maker the right, but not the obligation, to exercise actions at a later time. In previous work we introduced an integrated real options framework ...
  • Milicevic, Aleksandar; Jackson, Daniel; Gligoric, Milos; Marinov, Darko (Association for Computing Machinery (ACM), 2013-10)
    Applications are increasingly distributed and event-driven. Advances in web frameworks have made it easier to program standalone servers and their clients, but these applications remain hard to write. A model-based programming ...
  • Cummings, M. L.; Stimpson, Alexander J.; Buinhas, Luisa S.; Bezek, Scott; Boussemart, Yves (Human Factors and Ergonomics Society, 2012-09)
    Procedures play an important role in domains where humans interact with critical, complex systems. In such environments, the operator’s ability to correctly follow a given set of procedures can directly impact system safety. ...
  • Kashif, Faisal M.; Verghese, George C.; Heldt, Thomas; Novak, Vera; Czosnyka, Marek (American Association for the Advancement of Science (AAAS), 2012-04)
    Intracranial pressure (ICP) is affected in many neurological conditions. Clinical measurement of pressure on the brain currently requires placing a probe in the cerebrospinal fluid compartment, the brain tissue, or other ...
  • McGee, Sasha; Mirkovic, Jelena; Mardirossian, Vartan; Elackattu, Alphi; Yu, Chung-Chieh; Kabani, Sadru; Gallagher, George; Pistey, Robert; Galindo, Luis H.; Badizadegan, Kamran; Wang, Zimmern; Dasari, Ramachandra Rao; Feld, Michael S.; Grillone, Gregory (Society of Photo-optical Instrumentation Engineers, 2008-12)
    In order to evaluate the impact of anatomy on the spectral properties of oral tissue, we used reflectance and fluorescence spectroscopy to characterize nine different anatomic sites. All spectra were collected in vivo ...
  • Zavala, M.; Molina, Mario J.; Lei, Wenfang; Molina, Luisa Tan (Copernicus Publications on behalf of the European Geosciences Union, 2009-01)
    The emission characteristics of mobile sources in the Mexico City Metropolitan Area (MCMA) have changed significantly over the past few decades in response to emission control policies, advancements in vehicle technologies ...
  • Geramifard, Alborz; Redding, Joshua D.; Joseph, Joshua Mason (2012-06)
    Risk and reward are fundamental concepts in the cooperative control of unmanned systems. In this research, we focus on developing a constructive relationship between cooperative planning and learning algorithms to mitigate ...
  • Chakraborty, Arup K.; Meissner, Alexander; Artyomov, Maxim N. (Public Library of Science, 2010-05)
    With relatively low efficiency, differentiated cells can be reprogrammed to a pluripotent state by ectopic expression of a few transcription factors. An understanding of the mechanisms that underlie data emerging from such ...
  • Fowler, Kevin Daniel; Kuchroo, Vijay K.; Chakraborty, Arup K. (Public Library of Science, 2012-03)
    The reason why IL-6 induces a pro-inflammatory response, while IL-10 induces an anti-inflammatory response, despite both cytokines activating the same transcription factor, STAT3, is not well understood. It is known that ...
  • Kasimov, Aslan R.; Faria, Luiz M.; Rosales, Rodolfo R. (American Physical Society, 2013-03)
    We propose the following model equation, u[subscript t]+1/2(u[superscript 2]-uu[subscript s])[subscript x]=f(x,u[subscript s]) that predicts chaotic shock waves, similar to those in detonations in chemically reacting ...
  • Joh, Jungwoo; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers, 2008-03)
    We have found that there is a critical drain-to-gate voltage beyond which GaN high-electron mobility transistors start to degrade in electrical-stress experiments. The critical voltage depends on the detailed voltage biasing ...
  • Muller, Caroline; Back, Larissa E.; O'Gorman, Paul Ambrose; Emanuel, Kerry Andrew (American Geophysical Union, 2009-08)
    Several observational studies have shown a tight relationship between tropical precipitation and column-integrated water vapor. We show that the observed relationship in the tropics between column-integrated water vapor, ...
  • Choudhury, Charisma F.; Ramanujam, Varun; Ben-Akiva, Moshe E. (Transportation Research Board of the National Academies, 2009-12)
    In uncongested traffic situations, a merge is executed when the available gap is sufficiently large. However, in congested traffic, acceptable gaps for merging are often not readily available, and merging can involve more ...
