  • Pilawa-Podgurski, Robert C. N.; Perreault, David J. (Institute of Electrical and Electronics Engineers (IEEE), 2012-05)
    In this paper, we introduce a merged two-stage dc-dc power converter for low-voltage power delivery. By separating the transformation and regulation function of a dc-dc power converter into two stages, both large voltage ...
  • Lin, Ying-Tsong; Newhall, Arthur E.; Duda, Timothy F.; Lermusiaux, Pierre F. J.; Haley, Patrick J. (Institute of Electrical and Electronics Engineers, 2010-10)
    In this paper, a method for merging partial overlapping time series of ocean profiles into a single time series of profiles using empirical orthogonal function (EOF) decomposition with the objective analysis is presented. ...
  • Drake, Adam; Chen, Qingfeng; Dong, Di; Leskov, Ilya; Fragoso, Maria F.; Li, Yan; Iliopoulou, Bettina P.; Hwang, William; Lodish, Harvey F.; Chen, Jianzhu (Mary Ann Liebert, 2010-12)
    Clinical and preclinical applications of human hematopoietic stem cells (HSCs) are often limited by scarcity of cells. Expanding human HSCs to increase their numbers while maintaining their stem cell properties has therefore ...
  • Aloupis, Greg; Demaine, Erik D.; Demaine, Martin L.; Iacono, John; Dujmovic, Vida (Springer-Verlag, 2012)
    The minimum feature size of a planar straight-line graph is the minimum distance between a vertex and a nonincident edge. When such a graph is partitioned into a mesh, the degradation is the ratio of original to final ...
  • Amaro, J. E.; Barbaro, M. B.; Caballero, J. A.; Maieron, C.; Udias, J. M.; Donnelly, T. William (American Physical Society, 2010-01)
    The effects of meson-exchange currents (MEC) are computed for the one-particle one-hole transverse response function for finite nuclei at high momentum transfers q in the region of the quasi-elastic peak. A semirelativistic ...
  • Amaro, J. E.; Barbaro, M. B.; Caballero, J. A.; Donnelly, T. William (American Physical Society, 2012-04)
    We evaluate quasielastic double-differential antineutrino cross sections obtained in a phenomenological model based on the superscaling behavior of electron scattering data and estimate the contribution of the vector ...
  • Faulkner, Thomas; Liu, Hong (Elsevier, 2009-02)
    We show that open strings living on a D-brane which lies outside an AdS black hole We show that open strings living on a D-brane which lies outside an AdS black hole can tunnel into the black hole through worldsheet ...
  • Homer, Eric R.; Schuh, Christopher A. (Elsevier, 2009-03)
    A new mesoscale modeling technique for the thermo-mechanical behavior of metallic glasses is proposed. The modeling framework considers the shear transformation zone (STZ) as the fundamental unit of deformation, and ...
  • Sanghavi, Sujay; Shah, Devavrat; Willsky, Alan S. (2009-10)
    In this paper, we investigate the use of message-passing algorithms for the problem of finding the max-weight independent set (MWIS) in a graph. First, we study the performance of the classical loopy max-product belief ...
  • Giaccone, Paolo; Shah, Devavrat (Institute of Electrical and Electronics Engineers (IEEE), 2010-09)
    In the recent years, message-passing paradigm has emerged as a canonical algorithmic solution to solve networkwide problems by means of minimal local information exchange, across variety of disciplines. The primary purpose ...
  • Willsky, Alan S.; Kreidl, Olivier Patrick (Institute of Electrical and Electronics Engineers, 2010-01)
    Motivated by distributed inference applications in unreliable communication networks, we adapt the popular (sum-product) belief propagation (BP) algorithm under the constraint of discrete-valued messages. We show that, in ...
  • Johnson, Catherine L.; Purucker, Michael E.; Korth, Haje; Anderson, Brian J.; Winslow, Reka M.; Al Asad, Manar M. H.; Slavin, James A.; Alexeev, Igor. I.; Phillips, Roger J.; Zuber, Maria; Solomon, Sean C. (American Geophysical Union, 2012-12)
    We present a baseline, time-averaged model for Mercury's magnetosphere, derived from MESSENGER Magnetometer data from 24 March to 12 December 2011, comprising the spacecraft's first three Mercury years in orbit around the ...
  • Ueda, Satoshi; Fors, Brett P.; Ali, Siraj Z.; Buchwald, Stephen Leffler (American Chemical Society (ACS), 2012-02)
    A new biarylphosphine ligand, Me[subscript 3](OMe)tBuXPhos (L3), was designed as a surrogate for Me[subscript 4]tBuXPhos (L1). The Me[subscript 3](OMe)tBuXPhos could be prepared in a chromatography-free manner from inexpensive ...
  • Vander Heiden, Matthew G.; Davidson, Shawn Michael; Vander Heiden, Matthew G. (Elsevier, 2012-02)
    In this issue of Cell Metabolism, Yuneva et al. (2012) use mouse cancer models to characterize tumor nutrient metabolism in vivo. This study suggests that the metabolic phenotype of cancer cells is not only determined by ...
  • Libert, Sergiy V.; Guarente, Leonard Pershing (Annual Reviews, 201-10)
    Most living organisms, including humans, age. Over time the ability to do physical and intellectual work deteriorates, and susceptibility to infectious, metabolic, and neurodegenerative diseases increases, which leads to ...
  • Slavov, Nikolai G.; Macinskas, Joanna; Caudy, Amy; Botstein, David (National Academy of Sciences (U.S.), 2011-11)
    Despite rapid progress in characterizing the yeast metabolic cycle, its connection to the cell division cycle (CDC) has remained unclear. We discovered that a prototrophic batch culture of budding yeast, growing in a ...
  • Braakman, Rogier; Smith, Eric (Public Library of Science, 2014-2)
  • Rapoport, Benjamin I. (Public Library of Science, 2010-10)
    Each year in the past three decades has seen hundreds of thousands of runners register to run a major marathon. Of those who attempt to race over the marathon distance of 26 miles and 385 yards (42.195 kilometers), more ...
  • Rabani, Michal; Levin, Joshua Z.; Fan, Lin; Adiconis, Xian; Raychowdhury, Raktima; Garber, Manuel; Gnirke, Andreas; Nusbaum, Chad; Hacohen, Nir; Friedman, Nir; Amit, Ido; Regev, Aviv (Nature Publishing Group, 2011-04)
    Cellular RNA levels are determined by the interplay of RNA production, processing and degradation. However, because most studies of RNA regulation do not distinguish the separate contributions of these processes, little ...
  • Chindelevitch, Leonid; Regev, Aviv; Berger, Bonnie (Springer-Verlag, 2011)
    Metabolic networks are a representation of current knowledge about the metabolic reactions available to a given organism. These networks can be placed into various mathematical frameworks, of which the constraintbased ...
