      Gao, Ruixuan; Asano, Shoh M; Boyden, Edward (Biomed Central Ltd, 2017-06)

    • 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 ...

      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 ...

      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 ...
    • QCD PRECISION MEASUREMENTS AND STRUCTURE FUNCTION EXTRACTION AT A HIGH STATISTICS, HIGH ENERGY NEUTRINO SCATTERING EXPERIMENT: NuSOnG 

      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 ...
