  • Bimonte, Giuseppe; Emig, Thorsten; Kardar, Mehran (American Physical Society, 2014-10)
    We use a derivative expansion for gently curved surfaces to compute the leading and the next-to-leading curvature corrections to the Casimir-Polder interaction between a polarizable small particle and a nonplanar surface. ...
  • Zaheer, Saad; Rahi, Sahand Jamal; Emig, Thorsten; Jaffe, Robert L. (American Physical Society, 2010-11)
    We study the electromagnetic Casimir interaction of a compact object contained inside a closed cavity of another compact object. We express the interaction energy in terms of the objects’ scattering matrices and translation ...
  • Levin, Michael; McCauley, Alexander Patrick; Rodriguez, Alejandro W.; Reid, M. T. Homer; Johnson, Steven G. (American Physical Society, 2010-08)
    We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole. We prove that ...
  • Oliver, Trudy; Meylan, Etienne; Chang, Gregory P.; Xue, Wen; Burke, James R.; Humpton, Timothy J.; Hubbard, Diana D.; Bhutkar, Arjun (AJ); Jacks, Tyler E. (Elsevier, 2011-07)
    Caspase-2 is an evolutionarily conserved caspase, yet its biological function and cleavage targets are poorly understood. Caspase-2 is activated by the p53 target gene product PIDD (also known as LRDD) in a complex called ...
  • Li, Zheng; Jo, Jihoon; Jia, Jie-Min; Lo, Shih-Ching; Whitcomb, Daniel J.; Jiao, Song; Cho, Kwangwook; Sheng, Morgan (Elsevier, 2010-05)
    NMDA receptor-dependent synaptic modifications, such as long-term potentiation (LTP) and long-term depression (LTD), are essential for brain development and function. LTD occurs mainly by the removal of AMPA receptors from ...
  • Sun, Wei; Boulais, Etienne; Hakobyan, Yera; Wang, Wei Li; Guan, Amy; Bathe, Mark; Yin, Peng (American Association for the Advancement of Science (AAAS), 2014-10)
    We report a general strategy for designing and synthesizing inorganic nanostructures with arbitrarily prescribed three-dimensional shapes. Computationally designed DNA strands self-assemble into a stiff “nanomold” that ...
  • Szkody, Paula; Anderson, Scott F.; Hayden, Michael; Kronberg, Martin; McGurk, Rosalie; Riecken, Thomas; Schmidt, Gary D.; West, Andrew A.; Gansicke, Boris T.; Gomez-Moran, Ada N.; Schneider, Donald P.; Schreiber, Matthias R.; Schwope, Axel D. (IOP Publishing, 2009-03)
    Coordinates, magnitudes, and spectra are presented for 39 cataclysmic variables (CVs) found in Sloan Digital Sky Survey (SDSS) spectra that were primarily obtained in 2006. Of these, 13 were CVs identified prior to the ...
  • Muno, Michael P.; Bauer, Franz E.; Bandyopadhyay, R. M.; Bower, Geoffrey C.; Brandt, W. N.; Broos, P. S.; Cotera, A.; Eikenberry, S. S.; Garmire, Gordon P.; Hyman, S. D.; Kassim, N. E.; Lang, C. C.; Lazio, T. Joseph W.; Law, J. C.; Mauerhan, Jon C.; Morris, M. R.; Nagata, T.; Nishiyama, S.; Park, S.; Ramìrez, S. V.; Stolovy, S. R.; Wijnands, R.; Wang, Q. D.; Wang, Z.; Yusef-Zadeh, F.; Baganoff, Frederick K. (IOP Publishing, 2009-03)
    We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2°× 0°.8 field around the Galactic center. This enlarges the number of known X-ray sources in the region by a factor of 2.5. The catalog ...
  • Ueda, Satoshi; Buchwald, Stephen Leffler (Wiley Blackwell, 2012-09)
    What N would you like? The chemoselective and complementary Pd- and Cu-catalyzed N-arylation of 2-aminobenzimidazoles is described. Selective N-arylation of the amino group was achieved with a Pd-catalyzed method, while ...
  • Yu, Miao; Schrock, Richard Royce; Hoveyda, Amir H. (John Wiley & Sons, 2014-11)
    Molybdenum-, tungsten-, and ruthenium-based complexes that control the stereochemical outcome of olefin metathesis reactions have been recently introduced. However, the complementary nature of these systems through their ...
  • Sjolin-Goodfellow, Hanna; Frushicheva, Maria P.; Ji, Qinqin; Cheng, Debra A.; Kadlecek, Theresa A.; Cantor, Aaron J.; Kuriyan, John; Chakraborty, Arup K.; Salomon, Arthur R.; Weiss, Arthur (American Association for the Advancement of Science (AAAS), 2015-05)
    T cell activation by antigens binding to the T cell receptor (TCR) must be properly regulated to ensure normal T cell development and effective immune responses to pathogens and transformed cells while avoiding autoimmunity. ...
  • Ho, Chun-Yu; Chan, Chun-Wa; Schleicher, Kristin D.; Jamison, Timothy F. (Thieme Publishing Group, 2009-09)
    Recent advances using nickel complexes in the activation of unactivated monosubstituted olefins for catalytic intermolecular carbon-carbon bond-forming reactions with carbonyl compounds, such as simple aldehydes, isocyanates, ...
  • Yang, Yang; Shi, Shi-Liang; Niu, Dawen; Liu, Peng; Buchwald, Stephen Leffler (American Association for the Advancement of Science (AAAS), 2015-07)
    Catalytic assembly of enantiopure aliphatic amines from abundant and readily available precursors has long been recognized as a paramount challenge in synthetic chemistry. Here, we describe a mild and general copper-catalyzed ...
  • Liang, Yufan; Fu, Gregory C. (American Chemical Society (ACS), 2014-03)
    The development of new approaches to the construction of fluorine-containing target molecules is important for a variety of scientific disciplines, including medicinal chemistry. In this Article, we describe a method for ...
  • Fu, Gregory C.; Zultanski, Susan (American Chemical Society (ACS), 2011-09)
    With the aid of a chiral nickel catalyst, enantioselective γ- (and δ-) alkylations of carbonyl compounds can be achieved through the coupling of γ-haloamides with alkylboranes. In addition to primary alkyl nucleophiles, ...
  • Cordier, Christopher J.; Fu, Gregory C.; Binder, Jorg T. (American Chemical Society (ACS), 2012-10)
    We have developed a nickel-catalyzed method for the asymmetric cross-coupling of secondary electrophiles with secondary nucleophiles, specifically, stereoconvergent Negishi reactions of racemic benzylic bromides with achiral ...
  • Cong, Huan; Fu, Gregory C. (American Chemical Society (ACS), 2014-03)
    As part of our ongoing effort to expand the scope of cross-coupling reactions of alkyl electrophiles, we have pursued a strategy wherein the nucleophilic coupling partner includes a pendant olefin; after transmetalation ...
