      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 (2013-07)
      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-Deformed character theory for infinite-dimensional symplectic and orthogonal groups 

      Cuenca, Cesar; Gorin, Vadim (Springer International Publishing, 2020-06-12)
      Abstract The classification of irreducible, spherical characters of the infinite-dimensional unitary/orthogonal/symplectic groups can be obtained by finding all possible limits of normalized, irreducible ...
    • 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-learning with nearest neighbors 

      Shah, Devavrat; Xie, Qiaomin (2018)
      © 2018 Curran Associates Inc.All rights reserved. We consider model-free reinforcement learning for infinite-horizon discounted Markov Decision Processes (MDPs) with a continuous state space and unknown transition kernel, ...
    • 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 ...
    • A q-player impartial avoidance game for generating finite groups 

      Benesh, Bret J; Gaetz, Marisa R (Springer Berlin Heidelberg, 2018-05-10)
      Abstract We study a q-player variation of the impartial avoidance game introduced by Anderson and Harary, where q is a prime. The game is played by the q players taking turns selecting previously-unselected ...
    • 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 ...
    • Q[subscript weak]: First Direct Measurement of the Proton’s Weak Charge 

      Balewski, Jan T.; Guo, Fang; Kowalski, Stanley B; Rajotte, Jean-Francois (EDP Sciences, 2017-03)
      The Q[subscript weak] experiment, which took data at Jefferson Lab in the period 2010 - 2012, will precisely determine the weak charge of the proton by measuring the parity-violating asymmetry in elastic e-p scattering at ...
    • 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 ...

      Parotto, Paolo; Bluhm, Marcus; Mroczek, Debora; Nahrgang, Marlene; Noronha-Hostler, J.; e.a. (American Physical Society, 2020-03-02)
      We construct a family of equations of state for QCD in the temperature range 30MeV≤T≤800MeV and in the chemical potential range 0≤μ_{B}≤450MeV. These equations of state match available lattice QCD results up to O(μ_{B}^{4}) ...
    • 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 ...
