  • Ebrahimi, Davoud; Whittle, Andrew; Pellenq, Roland Jm (American Institute of Physics (AIP), 2014-04)
    Face-to-face and edge-to-edge free energy interactions of Wyoming Na-montmorillonite platelets were studied by calculating potential of mean force along their center to center reaction coordinate using explicit solvent ...
  • Ebrahimi, Davoud; Whittle, Andrew J.; Pellenq, Roland Jm; Whittle, Andrew (Springer Berlin Heidelberg, 2016-06)
    This paper proposes a novel methodology for understanding the meso-scale aggregation of clay platelets in water. We use Molecular Dynamics simulations using the CLAYFF force fields to represent the interactions between two ...
  • Bauchy, Mathieu; Masoero, Enrico; Levitz, Pierre; Del Gado, Emanuela; Ioannidou, Katerina; Krakowiak, Konrad J; Hoover, Christian G; Yip, Sidney; Ulm, Franz-Josef; Pellenq, Roland Jm (National Academy of Sciences (U.S.), 2016-02)
    Strength and other mechanical properties of cement and concrete rely upon the formation of calcium–silicate–hydrates (C–S–H) during cement hydration. Controlling structure and properties of the C–S–H phase is a challenge, ...
  • Yu, Zechuan; Zhou, Ao; Lau, Denvid (Nature Publishing Group, 2016-11)
    At 100-nanometer length scale, the mesoscopic structure of calcium silicate hydrate (C-S-H) plays a critical role in determining the macroscopic material properties, such as porosity. In order to explore the mesoscopic ...
  • Hall, Anthony Shoji; Yoon, Youngmin; Wuttig, Anna; Surendranath, Yogesh (American Chemical Society (ACS), 2015-11)
    Gold inverse opal (Au-IO) thin films are active for CO[subscript 2] reduction to CO with high efficiency at modest overpotentials and high selectivity relative to hydrogen evolution. The specific activity for hydrogen ...
  • Yu, Hang Z.; Cross, Samuel Robert; Schuh, Christopher A (Springer US, 2017-01)
    As multi-material additive manufacturing technologies mature, a new opportunity for materials science and engineering emerges between the scale of the microstructure and the scale of an engineering component. Here we explore ...
  • 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 ...
  • Vassio, Luca; Fagnani, Fabio; Frasca, Paolo; Ozdaglar, Asuman E. (Institute of Electrical and Electronics Engineers (IEEE), 2014-04)
    This paper proposes a new measure of node centrality in social networks, the Harmonic Influence Centrality (HIC), which emerges naturally in the study of social influence over networks. Using an intuitive analogy between ...
  • 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 ...
  • Gilbert, Wendy; Bell, Tristan Andrew; Schaening, Cassandra (American Association for the Advancement of Science (AAAS), 2016-06)
    RNA contains more than 100 distinct modifications that promote the functions of stable noncoding RNAs in translation and splicing. Recent technical advances have revealed widespread and sparse modification of messenger ...
  • 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 ...
  • Morfeld, Peter; Mundt, Kenneth; Dell, Linda; Sorahan, Tom; McCunney, Robert J (MDPI AG, 2016-03)
    Epidemiological studies have demonstrated associations between airborne environmental particle exposure and cardiac disease and mortality; however, few have examined such effects from poorly soluble particles of low toxicity ...
  • Irizarry, Rafael A.; Duvallet, Claire; Gibbons, Sean Michael; Gurry, Thomas Jerome; Alm, Eric J (Nature Publishing Group, 2017-12)
    Hundreds of clinical studies have demonstrated associations between the human microbiome and disease, yet fundamental questions remain on how we can generalize this knowledge. Results from individual studies can be ...
  • Burge, Christopher B.; Sudmant, Peter; Alexis, Maria Sarah (BioMed Central, 2015-12)
    Background Differences in gene expression drive phenotypic differences between species, yet major organs and tissues generally have conserved gene expression programs. Several comparative transcriptomic studies have ...
  • 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 ...
  • Go, Young-Mi; Liang, Yongliang; Uppal, Karan; Soltow, Quinlyn A.; Promislow, Daniel E. L.; Jones, Dean P.; Wachtman, Lynn M. (Public Library of Science, 2015-11)
    High-resolution metabolomics has created opportunity to integrate nutrition and metabolism into genetic studies to improve understanding of the diverse radiation of primate species. At present, however, there is very little ...
  • Cha, Young; Han, Min-Joon; Cha, Hyuk-Jin; Burkart, Alison; Jung, Jin Hyuk; Jang, Yongwoo; Kim, Chun-Hyung; Jeong, Ho-Chang; Kim, Byung-Gyu; Kahn, C. Ronald; Kim, Kwang-Soo; Zoldan, Janeta; Langer, Robert S; Guarente, Leonard Pershing (Nature Publishing Group, 2017-04)
    A hallmark of cancer cells is the metabolic switch from oxidative phosphorylation (OXPHOS) to glycolysis, a phenomenon referred to as the 'Warburg effect', which is also observed in primed human pluripotent stem cells ...
