  • More data means less inference: A pseudo-max approach to structured learning 
    Sontag, David; Meshi, Ofer; Jaakkola, Tommi S.; Globerson, Amir (Neural Information Processing Systems Foundation, 2010-12)
    The problem of learning to predict structured labels is of key importance in many applications. However, for general graph structure both learning and inference in this setting are intractable. Here we show that it is ...
  • A more effective way to label affective expressions 
    Eckhardt, Micah Rye; Picard, Rosalind W. (Institute of Electrical and Electronics Engineers, 2009-09)
    Labeling videos for affect content such as facial expression is tedious and time consuming. Researchers often spend significant amounts of time annotating experimental data, or simply lack the time required to label their ...
  • More on Haecceitism and Possible Worlds 
    Skow, Bradford (Wiley Blackwell (Blackwell Publishing), 2011-12)
    Anti-haecceitism is the thesis that the universe could not be nonqualitatively different without being qualitatively different. Haecceitism is the denial of anti-haecceitism.1 In “Haecceitism, Anti-Haecceitism, and ...
  • More on the antiautomorphism of the Steenrod algebra 
    Giambalvo, Vince; Miller, Haynes R. (Mathematical Sciences Publishers, 2011-09)
    The relations of Barratt and Miller are shown to include all relations among the elements P[superscript i]χP[superscript n−i} in the mod p Steenrod algebra, and a minimal set of relations is given.

    McKernan, James (Springer, 2010-04)
    We explore the circle of ideas connecting finite generation of the Cox ring, Mori dream spaces and invariant theory.
  • Morphogenetic and regulatory mechanisms during developmental chondrogenesis: New paradigms for cartilage tissue engineering 
    Quintana, Lluís; Nieden, Nicole I. zur; Semino, Carlos Eduardo (Mary Ann Liebert, 2008-12)
    Cartilage is the first skeletal tissue to be formed during embryogenesis leading to the creation of all mature cartilages and bones, with the exception of the flat bones in the skull. Therefore, errors occurring during ...
  • Morphological and molecular evidence for functional organization along the rostrocaudal axis of the adult zebrafish intestine 
    Wang, Zhengyuan; Du, Jianguo; Lam, Siew H.; Mathavan, Sinnakarupan; Matsudaira, Paul T.; Gong, Zhiyuan (BioMed Central Ltd., 2010-06)
    Background The zebrafish intestine is a simple tapered tube that is folded into three sections. However, whether the intestine is functionally similar along its length remains unknown. Thus, a systematic structural and ...
  • Morphological record of oxygenic photosynthesis in conical stromatolites 
    Petroff, Alexander Peter; Sim, Min Sub; Liang, Biqing; Bosak, Tanja (United States National Academy of Sciences, 2009-05)
    Conical stromatolites are thought to be robust indicators of the presence of photosynthetic and phototactic microbes in aquatic environments as early as 3.5 billion years ago. However, phototaxis alone cannot explain the ...
  • Morphology effects on non-isotropic thermal conduction of aligned single- and multi-walled carbon nanotubes in polymer nanocomposites 
    Duong, Hai M.; Yamamoto, Namiko; Bui, Khoa; Papavassiliou, Dimitrios V.; Maruyama, Shigeo; Wardle, Brian L. (American Chemical Society (ACS), 2010-04)
    Carbon nanotube (CNT)−CNT contact and CNT distribution effects on anisotropic thermal transport in aligned CNT−polymer nanocomposites (PNCs) are studied using an off-lattice Monte Carlo numerical simulation. Inter-CNT ...
  • Mosh: An Interactive Remote Shell for Mobile Clients 
    Winstein, Keith J.; Balakrishnan, Hari (Advanced Computing Systems Association, 2012-06)
    Mosh (mobile shell) is a remote terminal application that supports intermittent connectivity, allows roaming, and speculatively and safely echoes user keystrokes for better interactive response over high-latency paths. ...
  • Most mammalian mRNAs are conserved targets of microRNAs 
    Friedman, Robin Carl; Farh, Kyle Kai-How; Burge, Christopher B.; Bartel, David (Cold Spring Harbor Laboratory Press in association with The Genetics Society, 2008-10)
    MicroRNAs (miRNAs) are small endogenous RNAs that pair to sites in mRNAs to direct post-transcriptional repression. Many sites that match the miRNA seed (nucleotides 2–7), particularly those in 3′ untranslated regions ...
  • The Most Metal-Poor Stars. I. Discovery, Data, and Atmospheric Parameters 
    Frebel, Anna L.; Norris, John E.; Bessell, M. S.; Yong, David; Christlieb, N.; Barklem, P. S.; Asplund, M.; Murphy, Simon J.; Beers, Timothy C.; Ryan, S. G. (IOP Publishing, 2012-12)
    We report the discovery of 34 stars in the Hamburg/ESO Survey for metal-poor stars and the Sloan Digital Sky Survey that have [Fe/H] [< over ~]–3.0. Their median and minimum abundances are [Fe/H] = –3.1 and –4.1, respectively, ...
  • The Most Metal-Poor Stars. II. Chemical Abundances of 190 Metal-Poor Stars Including 10 New Stars With [Fe/H] ≤ -3.5 
    Frebel, Anna L.; Yong, David; Bessell, M. S.; Christlieb, N.; Asplund, M.; Beers, Timothy C.; Barklem, P. S.; Ryan, S. G.; Norris, John E. (IOP Publishing, 2012-12)
    We present a homogeneous chemical abundance analysis of 16 elements in 190 metal-poor Galactic halo stars (38 program and 152 literature objects). The sample includes 171 stars with [Fe/H] ≤ –2.5, of which 86 are extremely ...
  • The Most Metal-Poor Stars. III. The Metallicity Distribution Function and CEMP Fraction 
    Frebel, Anna L.; Yong, David; Norris, John E.; Bessell, M. S.; Christlieb, N.; Asplund, M.; Beers, Timothy C.; Barklem, P. S.; Ryan, S. G. (IOP Publishing, 2012-12)
    We examine the metallicity distribution function (MDF) and fraction of carbon-enhanced metal-poor (CEMP) stars in a sample that includes 86 stars with [Fe/H] ≤ –3.0, based on high-resolution, high signal-to-noise spectroscopy, ...
  • The Most Metal-Poor Stars. IV. The Two Populations With [Fe/H] [< over ~] -3.0

  • Motif Discovery in Physiological Datasets: A Methodology for Inferring Predictive Elements 
    Syed, Zeeshan; Stultz, Collin M.; Kellis, Manolis; Indyk, Piotr; Guttag, John V. (Association for Computing Machinery (ACM), 2010-01)
    In this article, we propose a methodology for identifying predictive physiological patterns in the absence of prior knowledge. We use the principle of conservation to identify activity that consistently precedes an outcome ...
  • Motion blur removal with orthogonal parabolic exposures 
    Cho, Taeg Sang; Levin, Anat; Durand, Fredo; Freeman, William T. (Institute of Electrical and Electronics Engineers, 2010-03)
    Object movement during exposure generates blur. Removing blur is challenging because one has to estimate the motion blur, which can spatially vary over the image. Even if the motion is successfully identified, blur removal ...
