    • Q measurements for high-Q cavities 

      Rapuano, Robert A.; Halpern, J. (Research Laboratory of Electronics, Massachusetts Institute of Technology, 1946)
    • Q&A: Expansion microscopy 

      Gao, Ruixuan; Asano, Shoh M; Boyden, Edward (Biomed Central Ltd, 2017-06)
      Expansion microscopy (ExM) is a recently invented technology that uses swellable charged polymers, synthesized densely and with appropriate topology throughout a preserved biological specimen, to physically magnify the ...
    • A (-q)-analogue of weight multiplicities 

      Lusztig, George; Yun, Zhiwei
      We prove a conjecture in [L11] stating that certain polynomials P-Y(sigma),(w)(q) introduced in [LV11] for twisted involutions in an affine Weyl group give ( -q)-analogues of weight multiplicities of the Langlands dual ...
    • The q-AGT–W Relations Via Shuffle Algebras 

      Negut, Andrei (Springer Berlin Heidelberg, 2018-02-21)
      We construct the action of the q-deformed W-algebra on its level r representation geometrically, using the moduli space of U(r) instantons on the plane and the double shuffle algebra. We give an explicit LDU decomposition ...
    • A q-analogue of spanning trees : nilpotent transformations over finite fields 

      Yin, Jingbin (Massachusetts Institute of Technology, 2009)
      The main result of this work is a q-analogue relationship between nilpotent transformations and spanning trees. For example, nilpotent endomorphisms on an n-dimensional vector space over Fq is a q-analogue of rooted spanning ...
    • Q-Learning and Enhanced Policy Iteration in Discounted Dynamic Programming 

      Bertsekas, Dimitri P; Yu, Huizhen (Institute for Operations Research and the Management Sciences (INFORMS), 2012-02)
      We consider the classical finite-state discounted Markovian decision problem, and we introduce a new policy iteration-like algorithm for finding the optimal state costs or Q-factors. The main difference is in the policy ...
    • Q-learning and policy iteration algorithms for stochastic shortest path problems 

      Yu, Huizhen; Bertsekas, Dimitri P. (Springer-Verlag, 2012-04)
      We consider the stochastic shortest path problem, a classical finite-state Markovian decision problem with a termination state, and we propose new convergent Q-learning algorithms that combine elements of policy iteration ...
    • Q-particles and the nature of covert movement: Evidence from Bùlì 

      Sulemana, Abdul-Razak (Ubiquity Press, Ltd., 2019-08-23)
      There are a number of intriguing issues surrounding wh-questions that have drawn considerable attention in the literature. Among the most commonly observed is the fact that in certain languages, wh-phrases move overtly ...
    • The q-PushASEP: A New Integrable Model for Traffic in 1+1 Dimension 

      Corwin, Ivan; Petrov, Leonid (Springer-Verlag, 2015-02)
      We introduce a new interacting (stochastic) particle system q-PushASEP which interpolates between the q [italicized q]-TASEP of Borodin and Corwin (Probab Theory Relat Fields 158(1–2):225–400, 2014; see also Borodin et ...
    • The Q[superscript p][subscript Weak] experiment 

      Androic, D.; Armstrong, D. S; Asaturyan, A.; Averett, T.; Beaufait, J.; e.a. (Springer-Verlag, 2013-02)
      In May 2012, the Q[superscript p][subscript Weak] collaboration completed a two year measurement program to determine the weak charge of the proton Q[superscript p][subscript Weak] = ( 1 - 4sin [superscript 2] θ[subscript ...
    • QCD axion window and low-scale inflation 

      Yin, Wen; Takahashi, Fuminobu; Guth, Alan (American Physical Society, 2018-07)
      We show that the upper bound of the classical QCD axion window can be significantly relaxed for low-scale inflation. If the Gibbons-Hawking temperature during inflation is lower than the QCD scale, the initial QCD axion ...
    • QCD inequalities for hadron interactions 

      Detmold, William (American Physical Society, 2015-06)
      We derive generalizations of the Weingarten-Witten QCD mass inequalities for particular multihadron systems. For systems of any number of identical pseudoscalar mesons of maximal isospin, these inequalities prove that near ...

      Conrad, Janet; Fisher, Peter H.; Formaggio, Joseph A.; Karagiorgi, Georgia Stelios; Milner, Richard G.; e.a. (World Scientific, 2010-01)
      We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction ...
    • QED radiative corrections to low-energy Møller and Bhabha scattering 

      Epstein, Charles S.; Milner, Richard G (American Physical Society, 2016-08)
      We present a treatment of the next-to-leading-order radiative corrections to unpolarized Møller and Bhabha scattering without resorting to ultrarelativistic approximations. We extend existing soft-photon radiative corrections ...

      The mainstream commercialization of colloidal quantum dots (QDs) for light-emitting applications has begun: Sony televisions emitting QD-enhanced colors are now on sale. The bright and uniquely size-tunable colors of ...
    • QnAs with Susan L. Lindquist 

      Nair, Prashant; Lindquist, Susan (National Academy of Sciences of the United States of America, 2011-11)
      Prions defy molecular biology’s central dogma. Misfolded proteins that self-perpetuate, prions were first isolated in the early 1980s as the cause of a fatal sheep disease called scrapie. Since then, prions have been ...
