  • Flint, Rebecca; Todadri, Senthil (American Physical Society, 2013-03)
    Motivated by the potential chiral spin liquid in the metallic spin ice Pr[subscript 2]Ir[subscript 2]O[subscript 7], we consider how such a chiral state might be selected from the spin-ice manifold. We propose that chiral ...
  • Chubukov, Andrey V.; Nandkishore, Rahul Mahajan; Levitov, Leonid (2012-01)
    Chiral superconductivity, which breaks time-reversal symmetry, can exhibit a wealth of fascinating properties that are highly sought after for nanoscience applications. We identify doped graphene monolayer as a system where ...
  • Chen, Xie; Wen, Xiao-Gang (American Physical Society, 2012-12)
    Symmetry protected topological (SPT) states are short-range entangled states with symmetry. The boundary of a SPT phases has either gapless excitations or degenerate ground states, around a gapped bulk. Recently, we proposed ...
  • Abeysekera, Chamara; Zack, Lindsay N.; Park, Barratt; Joalland, Baptiste; Oldham, James M.; Prozument, Kirill; Ariyasingha, Nuwandi M.; Sims, Ian R.; Field, Robert W.; Suits, Arthur G. (American Institute of Physics (AIP), 2014-12)
    This second paper in a series of two reports on the performance of a new instrument for studying chemical reaction dynamics and kinetics at low temperatures. Our approach employs chirped-pulse Fourier-transform microwave ...
  • Prozument, Kirill; Colombo, Anthony P.; Zhou, Yan; Park, Barratt; Petrovic, Vladimir S.; Coy, Stephen L.; Field, Robert W. (American Physical Society (APS), 2011-09)
    Transitions between Rydberg states of Ca atoms, in a pulsed, supersonic atomic beam, are directly detected by chirped-pulse millimeter-wave spectroscopy. Broadband, high-resolution spectra with accurate relative intensities ...
  • Colombo, Anthony P.; Zhou, Yan; Prozument, Kirill; Coy, Stephen L.; Field, Robert W. (American Institute of Physics, 2013)
    We apply the chirped-pulse millimeter-wave (CPmmW) technique to transitions between Rydberg states in calcium atoms. The unique feature of Rydberg–Rydberg transitions is that they have enormous electric dipole transition ...
  • Misailovic, Sasa; Achour, Sara; Qi, Zichao; Rinard, Martin C.; Carbin, Michael James (Association for Computing Machinery (ACM), 2014-10)
    The accuracy of an approximate computation is the distance between the result that the computation produces and the corresponding fully accurate result. The reliability of the computation is the probability that it will ...
  • Paluska, Justin Mazzola; Ward, Stephen A. (Institute of Electrical and Electronic Engineers, 2010-03)
    We propose a model for reliable remote storage founded on contract law. Consumers submit their bits to storage providers in exchange for a chit. A chit is a cryptographically secure, verifiable contract between a consumer ...
  • Abaluck, Jason; Gruber, Jonathan (American Economic Association, 2011-06)
    We evaluate the choices of elders across their insurance options under the Medicare Part D Prescription Drug plan, using a unique dataset of prescription drug claims matched to information on the characteristics of choice ...
  • Bertuccelli, Luca F.; Pellegrino, Nicholas A.; Cummings, M. L. (American Automatic Control Council, 2010-06)
    This paper addresses human decision-making in supervisory control of a team of unmanned vehicles performing search missions. Previous work has proposed the use of a two-alternative choice framework, in which operators ...
  • Olvera-Gomez, Irlanda; Hamilton, Sara E.; Xiao, Zhengguo; Guimaraes, Carla P.; Ploegh, Hidde; Hogquist, Kristin A.; Wang, Liangchun; Jameson, Stephen C. (National Academy of Sciences, 2012-01)
    The ability to induce humoral and cellular immunity via antigen delivery through the unbroken skin (epicutaneous immunization, EPI) has immediate relevance for vaccine development. However, it is unclear which adjuvants ...
  • Sengupta, Poulomi; Basu, Sudipta; Soni, Shivani; Pandey, Ambarish; Roy, Bhaskar; Oh, Michael S.; Chin, Kenneth T.; Paraskar, Abhimanyu S.; Sarangi, Sasmit; Connor, Yamicia D.; Sabbisetti, Venkata; Kopparam, Jawahar; Kulkarni, Ashish; Muto, Katherine; Amarasiriwardena, Chitra; Jayawardene, Innocent; Lupoli, Nicola; Dinulescu, Daniela M.; Bonventre, Joseph V.; Mashelkar, Raghunath Anant; Sengupta, Shiladitya (National Academy of Sciences (U.S.), 2012-07)
    Nanoscale drug delivery vehicles have been harnessed extensively as carriers for cancer chemotherapeutics. However, traditional pharmaceutical approaches for nanoformulation have been a challenge with molecules that exhibit ...
  • Chubykin, Alexander A.; Roach, Emma B.; Shuler, Marshall G. Hussain; Bear, Mark; Chubykin, Alexander A. (Elsevier, 2013-02)
    Neurons in rodent primary visual cortex (V1) relate operantly conditioned stimulus-reward intervals with modulated patterns of spiking output, but little is known about the locus or mechanism of this plasticity. Here we ...
  • Bloem, Bernard; Poorthuis, Rogier B.; Mansvelder, Huibert D. (Frontiers Research Foundation, 2014-03)
    Acetylcholine (ACh) release in the medial prefrontal cortex (mPFC) is crucial for normal cognitive performance. Despite the fact that many have studied how ACh affects neuronal processing in the mPFC and thereby influences ...
  • Abrahamsson, Christoffer K.; Yang, Fan; Park, Hyoungshin; Brunger, Jonathan M.; Valonen, Piia K.; Langer, Robert; Welter, Jean F.; Caplan, Arnold I.; Guilak, Farshid; Freed, Lisa E. (Mary Ann Liebert, Inc., 2010-07)
    Human mesenchymal stem cells (hMSCs) and three-dimensional (3D) woven poly(ɛ-caprolactone) (PCL) scaffolds are promising tools for skeletal tissue engineering. We hypothesized that in vitro culture duration and medium ...
  • Shu, K.; Thatte, H.; Spector, Myron (Institute of Electrical and Electronics Engineers, 2009-05)
    Mesenchymal stem cell (MSC) contraction associated with chondrogenesis is attributed to the expression of alpha-smooth muscle actin (alpha-SMA). In this study, pluripotent embryonic carcinoma cells (ECCs) and MSCs were ...
  • Imbens, Guido W.; Donald, Stephen G.; Newey, Whitney K. ()
    Properties of GMM estimators are sensitive to the choice of instruments. Using many instruments leads to high asymptotic asymptotic efficiency but can cause high bias and/or variance in small samples. In this paper we ...
  • Luo, Linjie; Baran, Ilya; Rusinkiewicz, Szymon; Matusik, Wojciech (Association for Computing Machinery (ACM), 2012-11)
    3D printing technology is rapidly maturing and becoming ubiquitous. One of the remaining obstacles to wide-scale adoption is that the object to be printed must fit into the working volume of the 3D printer. We propose a ...

    The marine cyanobacterium Prochlorococcus MED4 has the smallest genome and cell size of all known photosynthetic organisms. Like all phototrophs at temperate latitudes, it experiences predictable daily variation in available ...
