  • Oliveira, M. J.; Peixoto, A. C.; Correia, J. H.; Goncalves, S. B; Silva, A. F. (Springer London, 2015-10)
    \This paper describes an optimized out-of-plane fabrication method for neural 3D high-aspect-ratio microelectrode array (MEA) based on a dicing technology platform (a standard procedure in semiconductor industry). The ...
  • Phithakkitnukoon, Santi; Calabrese, Francesco; Smoreda, Zbigniew; Ratti, Carlo (Institute of Electrical and Electronics Engineers (IEEE), 2011-10)
    In this work we use anonymous telecommunication data to investigate how migration influences the dynamics of mobile social networks. We analyze the evolution of social ties for an entire country over a period of 11 months, ...
  • Kelley, Wyn (Wiley Blackwell, 2011-03)
    Late-twentieth-century digital archives of canonical authors have produced uncommonly expansive texts. Whereas once editors had to squeeze a book, with notes, glossaries, bibliographies, lists of variants, illustrations, ...
  • Madsen, Mickey P.; Perreault, David J.; Knott, Arnold; Andersen, Michael A. E. (Institute of Electrical and Electronics Engineers (IEEE), 2015-07)
    In this paper an outphasing modulation control method suitable for line regulation of very high frequency resonant converters is described. The pros and cons of several control methods suitable for very high frequency ...
  • Dawson, Joel L.; Perreault, David J.; Godoy, Philip Andrew (2009-12)
    We describe a new outphasing energy recovery amplifier (OPERA) which replaces the isolation resistor in the conventional matched combiner with a resistance-compressed rectifier for improved efficiency. The rectifier recovers ...

  • Manchester, Ian; Slotine, Jean-Jacques E (Institute of Electrical and Electronics Engineers, 2014-11)
    Control contraction metrics (CCMs) are a new approach to nonlinear control design based on contraction theory. The resulting design problems are expressed as pointwise linear matrix inequalities and are and well-suited to ...
  • Merer, Anthony J.; Field, Robert W.; Baraban, Joshua H.; Changala, Peter Bryan; Steeves, Adam; Bechtel, Hans A. (Taylor & Francis, 2012-11)
    The ungerade vibrational levels of the [~ over A] [superscript 1]A[subscript u] (S[subscript 1]-trans) state of C[subscript 2]H[subscript 2] lying in the region 45,800–46,550 cm[superscript −1] have been assigned from IR–UV ...
  • Youngsaye, Willmen; Dockendorff, Chris; Hartland, Cathy L.; Bittker, Joshua A.; Dandapani, Sivaraman; Palmer, Michelle; Whitesell, Luke; Lindquist, Susan; Schreiber, Stuart L.; Munoz, Benito (Elsevier B.V., 2012-05)
    Continuing efforts to discover novel means of combating fluconazole resistance in Candida albicans have identified an indole derivative that sensitizes strains demonstrating resistance to fluconazole. This tetracycle (3, ...
  • Biggs, Bradley Walters; Lim, Chin Giaw; Sagliani, Kristen; Shankar, Smriti; Ajikumar, Parayil Kumaran; Stephanopoulos, Gregory; De Mey, Marjan (National Academy of Sciences (U.S.), 2016-03)
    Recent advances in metabolic engineering have demonstrated the potential to exploit biological chemistry for the synthesis of complex molecules. Much of the progress to date has leveraged increasingly precise genetic tools ...
  • Frank, Michael C.; Gibson, Edward A. (Taylor & Francis, 2011-03)
    Adults, infants, and other species are able to learn and generalize abstract patterns from sequentially presented stimuli. Rule learning of this type may be involved in children's acquisition of linguistic structure, but ...
  • Liu, Adrian Chi-Yan; Hewitt, Jacqueline N.; Morgan, Edward H.; Levine, Alan M.; Morales, Miguel F.; Tingay, Steven J.; Bernardi, G.; Bowman, Judd D.; Briggs, Frank H.; Emrich, David; Mitchell, Daniel A.; Oberoi, Divya; Prabu, Thiagaraj; Wayth, Randall; Webster, Rachel L.; Dillon, Joshua Shane; Williams, Christopher Leigh; Tegmark, Max Erik; Cappallo, Roger J. (American Physical Society, 2014-01)
    We present techniques for bridging the gap between idealized inverse covariance weighted quadratic estimation of 21 cm power spectra and the real-world challenges presented universally by interferometric observation. By ...
  • Ilic, Ognjen; Jablan, Marinko; Joannopoulos, John D.; Celanovic, Ivan; Soljacic, Marin (Optical Society of America, 2012-03)
    Near-field thermophotovoltaic (TPV) systems with carefully tailored emitter-PV properties show large promise for a new temperature range (600 – 1200K) solid state energy conversion, where conventional thermoelectric (TE) ...
  • Choi, Youngwoon; Yang, Taeseok Daniel; Fang-Yen, Chris; Kang, Pilsung; Lee, Kyoung Jin; Dasari, Ramachandra Rao; Feld, Michael S.; Choi, Wonshik (American Physical Society, 2011-07)
    We report that disordered media made of randomly distributed nanoparticles can be used to overcome the diffraction limit of a conventional imaging system. By developing a method to extract the original image information ...
  • Larson, Erin B.; Graham, Danielle L.; Arzaga, Rose R.; Buzin, Nicole; Webb, Joseph; Green, Thomas A.; Bass, Caroline E.; Neve, Rachael L.; Terwilliger, Ernest F.; Nestler, Eric J.; Self, David W. (Society for Neuroscience, 2011-11)
    Chronic exposure to addictive drugs enhances cAMP response element binding protein (CREB)-regulated gene expression in nucleus accumbens (NAc), and these effects are thought to reduce the positive hedonic effects of passive ...
  • Yin, Yeshi; Withers, T. Ryan; Wang, Xin; Yu, Hongwei D.; de Regt, Anna Katherine; Baker, Tania; Sauer, Robert T (Wiley Blackwell, 2014-07)
    In Pseudomonas aeruginosa, alginate overproduction, also known as mucoidy, is negatively regulated by the transmembrane protein MucA, which sequesters the alternative sigma factor AlgU. MucA is degraded via a proteolysis ...
  • Ilker, Efe; Berker, A. Nihat (American Physical Society, 2014-04)
    In spin-glass systems, frustration can be adjusted continuously and considerably, without changing the antiferromagnetic bond probability p, by using locally correlated quenched randomness, as we demonstrate here on ...
