  • Demaine, Erik D.; Viglietta, Giovanni; Williams, Aaron (2016-06)
    Mario is back! In this sequel, we prove that solving a generalized level of Super Mario Bros. is PSPACE-complete, strengthening the previous NP-hardness result (FUN 2014). Both our PSPACE-hardness and the previous NP-hardness ...
  • Gelfand, Joseph D.; Castro, Daniel; Slane, Patrick O.; Temim, Tea; Hughes, John P.; Rakowski, Cara (Institute of Physics/American Astronomical Society, 2013-11)
    The supernova remnant Kes 17 (SNR G304.6+0.1) is one of a few but growing number of remnants detected across the electromagnetic spectrum. In this paper, we analyze recent radio, X-ray, and γ-ray observations of this object, ...
  • Slane, Patrick; Bykov, Andrei; Dubner, Gloria; Castro, Daniel; Ellison, Donald C. (Springer Netherlands, 2014-07)
    The giant molecular clouds (MCs) found in the Milky Way and similar galaxies play a crucial role in the evolution of these systems. The supernova explosions that mark the death of massive stars in these regions often lead ...
  • Ort, Moses Teddy; Wu, Faye Y; Hensel, Nicholas Charles; Asada, Haruhiko (ASME International, 2015-10)
    Patients with hemiparesis often have limited functionality in the left or right hand. The standard therapeutic approach requires the patient to attempt to make use of the weak hand even though it is not functionally capable, ...
  • Erez, Uri; Wornell, Gregory W. (Institute of Electrical and Electronics Engineers (IEEE), 2011-09)
    A natural joint physical and link layer transmission architecture is developed for communication over underwater acoustic channels, based on the concept of super-Nyquist (SNQ) signaling. In such systems, the signaling rate ...
  • Campos, Raymond; Guenthner, Andrew J.; Meuler, Adam J.; Tuteja, Anish; Cohen, Robert E.; McKinley, Gareth H.; Haddad, Timothy S.; Mabry, Joseph M. (American Chemical Society (ACS), 2012-05)
    The liquid repellency and surface topography characteristics of coatings comprising a sprayed-on mixture of fluoroalkyl-functional precipitated silica and a fluoropolymer binder were examined using contact and sliding angle ...
  • So, Peter T. C.; Heemskerk, Johannes Antonius; Tucker-Kellogg, Lisa; Nguyen, Binh P. (BioMed Central, 2016-12)
    Background Confetti fluorescence and other multi-color genetic labelling strategies are useful for observing stem cell regeneration and for other problems of cell lineage tracing. One difficulty of such strategies is ...
  • Dyer, Ethan Stanley; Sonner, Julian; Crossley, Michael J. (Springer-Verlag, 2014-12)
    We compute the supersymmetric Rényi entropies across a spherical entanglement surface in N = 4 SU(N) SYM theory using localization on the four-dimensional ellipsoid. We extract the leading result at large N and λ and match ...
  • Taylor, Dane; Mucha, Peter J.; Caceres, Rajmonda S. (American Physical Society, 2017-09)
    Applied network science often involves preprocessing network data before applying a network-analysis method, and there is typically a theoretical disconnect between these steps. For example, it is common to aggregate ...
  • Moitra, Ankur (ACM Symposium on Theory of Computing. Proceedings, 2015-06)
    Super-resolution is a fundamental task in imaging, where the goal is to extract fine-grained structure from coarse-grained measurements. Here we are interested in a popular mathematical abstraction of this problem that has ...
  • Johnson-Buck, Alexander; Nangreave, Jeanette; Kim, Do-Nyun; Bathe, Mark; Yan, Hao; Walter, Nils G. (American Chemical Society (ACS), 2013-01)
    We employ the single-particle fluorescence nanoscopy technique points accumulation for imaging in nanoscale topography (PAINT) using site-specific DNA probes to acquire two-dimensional density maps of specific features ...
  • Ikeda, Shiro; Tazaki, Fumie; Kuramochi, Kazuki; Broderick, Avery E.; Dexter, Jason; Mościbrodzka, Monika; Honma, Mareki; Doeleman, Sheperd S.; Akiyama, Kazunori; Pleau, Mollie; Fish, Vincent L.; Gowanlock, Michael G (IOP Publishing, 2017-03)
    We propose a new technique for radio interferometry to obtain superresolution full-polarization images in all four Stokes parameters using sparse modeling. The proposed technique reconstructs the image in each Stokes ...
  • Cho, Won-ki; Jayanth, Namrata; Mullen, Susan; Tan, Tzer Han; Jung, Yoon; Cisse, Ibrahim I (Nature Publishing Group, 2016-10)
    Live cell imaging of mammalian RNA polymerase II (Pol II) has previously relied on random insertions of exogenous, mutant Pol II coupled with the degradation of endogenous Pol II using a toxin, α-amanitin. Therefore, it ...
  • Boettiger, Alistair N.; Bintu, Bogdan; Moffitt, Jeffrey R.; Wang, Siyuan; Beliveau, Brian J.; Wu, Chao-ting; Zhuang, Xiaowei; Fudenberg, Geoffrey; Imakaev, Maksim Viktorovich; Mirny, Leonid A (Nature Publishing Group, 2016-01)
    Metazoan genomes are spatially organized at multiple scales, from packaging of DNA around individual nucleosomes to segregation of whole chromosomes into distinct territories. At the intermediate scale of kilobases to ...
  • Eldar, Yonina C.; Bhandari, Ayush; Raskar, Ramesh (Institute of Electrical and Electronics Engineers (IEEE), 2015-08)
    This work considers the problem of super-resolution. The goal is to resolve a Dirac distribution from knowledge of its discrete, low-pass, Fourier measurements. Classically, such problems have been dealt with parameter ...
  • Sagarra, Oleguer; Szell, Michael; Santi, Paolo; Ratti, Carlo; Diaz-Guilera, Albert; Sagarra. Oleguer (Public Library of Science, 2015-08)
    Understanding human mobility is of vital importance for urban planning, epidemiology, and many other fields that draw policies from the activities of humans in space. Despite the recent availability of large-scale data ...
  • Recht, Daniel; Smith, Matthew J.; Charnvanichborikarn, Supakit; Sullivan, Joseph T.; Winkler, Mark T.; Mathews, Jay; Warrender, Jeffrey M.; Buonassisi, Tonio; Williams, James S.; Aziz, Michael J.; Gradecak, Silvija (American Institute of Physics (AIP), 2013-09)
    We investigate the possibility of creating an intermediate band semiconductor by supersaturating Si with a range of transition metals (Au, Co, Cr, Cu, Fe, Pd, Pt, W, and Zn) using ion implantation followed by pulsed laser ...
  • Maieron, C.; Amaro, J. E.; Barbaro, M. B.; Caballero, J. A.; Donnelly, T. William; Williamson, Claude F. (American Physical Society, 2009-09)
    The present study focuses on the superscaling behavior of electron-nucleus cross sections in the region lying above the quasielastic peak, especially the region dominated by electroexcitation of the Δ. Non-quasielastic ...
  • Lewandowski, Jozef R.; Paepe, Gael De; Eddy, Matthew Thomas; Griffin, Robert Guy (American Chemical Society (ACS), 2009-04)
    We describe a new magic angle spinning (MAS) NMR experiment for obtaining [superscript 15]N−[superscript 15]N correlation spectra. The approach yields direct information about the secondary and tertiary structure of proteins, ...
  • Sochor, F.; Müller, D.; Richter, C.; Fürtig, B.; Schwalbe, H.; Silvers, Robert Paul Georg (Springer Netherlands, 2015-12)
    In comparison to proteins and protein complexes, the size of RNA amenable to NMR studies is limited despite the development of new isotopic labeling strategies including deuteration and ligation of differentially labeled ...
