    We have developed a novel strategy for simultaneous interpolation and denoising of prestack seismic data. Most seismic surveys fail to cover all possible source-receiver combinations, leading to missing data especially in ...
  • Gehring, Mary; Erdmann, Robert Michael; Souza, Amanda L.; Clish, Clary (Genetics Society of America, The, 2014-11)
    5-Hydroxymethylcytosine (5-hmC) is an intermediate in active demethylation in metazoans, as well as a potentially stable epigenetic mark. Previous reports investigating 5-hydroxymethylcytosine in plants have reached ...
  • Rajadurai, Charles V.; Havrylov, Serhiy; Coelho, Paula P.; Ratcliffe, Colin D.H.; Zaoui, Kossay; Huang, Bruce H.; Monast, Anie; Chughtai, Naila; Sangwan, Veena; Siegel, Peter M.; Park, Morag; Gertler, Frank (Rockefeller University Press, 2016-09)
    Invadopodia are specialized membrane protrusions that support degradation of extracellular matrix (ECM) by cancer cells, allowing invasion and metastatic spread. Although early stages of invadopodia assembly have been ...
  • Kim, Tae-Woo; Kim, Dae-Hyun; del Alamo, Jesus A. (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
    We have developed a new self-aligned gate technology for InGaAs High Electron Mobility Transistors with non-alloyed Mo-based ohmic contacts and a very low parasitic capacitance gate design. The new process delivers a contact ...
  • Verma, Naveen; Ramadass, Yogesh Kumar; Kwong, Joyce; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2008-12)
    Aggressive supply voltage scaling to below the device threshold voltage provides significant energy and leakage power reduction in logic and SRAM circuits. Consequently, it is a compelling strategy for energy-constrained ...
  • Daly, Denis C.; Chandrakasan, Anantha P. (Institute of Electrical and Electronics Engineers, 2009-08)
    A 6-bit highly digital flash ADC is implemented in a 0.18 mum CMOS process. The ADC operates in the subthreshold regime down to 200 mV and employs comparator redundancy and reconfigurability to improve linearity. The ...
  • Martini, Gabriella; Taylor, Washington (Springer-Verlag, 2015-06)
    We carry out a systematic study of a class of 6D F-theory models and associated Calabi-Yau threefolds that are constructed using base surfaces with a generalization of toric structure. In particular, we determine all smooth ...
  • Kumar, Vijay; Park, Daniel S.; Taylor, Washington (Springer-Verlag/International School for Advanced Studies (SISSA), 2011-04)
    We systematically investigate the finite set of possible gauge groups and matter content for supergravity theories in six dimensions with no tensor multiplets, focusing on nonabelian gauge groups which are a product of ...
  • Chandrakasan, Anantha P.; Price, Michael R.; Glass, James R. (Institute of Electrical and Electronics Engineers (IEEE), 2014-12)
    We describe an IC that provides a local speech recognition capability for a variety of electronic devices. We start with a generic speech decoder architecture that is programmable with industry-standard WFST and GMM speech ...
  • Dawson, Joel L.; Chung, SungWon (VLSI-TSA, 2009-04)
    We present a digitally assisted subsampler, designed to serve as the downconversion path in adaptive predistorters for 800MHz–5.8GHz RF power amplifiers. We use digital averaging to overcome the noise folding problems ...
  • Nguyen, Khoa M.; Kim, Helen H.; Sodini, Charles G. (Institute of Electrical and Electronics Engineers (IEEE), 2010-01)
    A 76 GHz phase-locked loop (PLL) was designed in 0.13 μm IBM BiCMOS8HP technology with the intended application of millimeter-wave imaging. The PLL has a type II second order loop filter. The voltage-controlled oscillator ...
  • Park, Matthew; Perrott, Michael H. (Institute of Electrical and Electronics Engineers, 2009-12)
    The use of a VCO-based integrator and quantizer within a continuous-time (CT) \Delta \Sigma analog-to-digital converter (ADC) structure is explored, and a custom prototype in a 0.13 \mum CMOS with a measured performance ...
