Finite-action approximation of Markov decision processes
(Birkhäuser Basel, 2018)In this chapter, we study the finite-action approximation of optimal control policies for discrete-time Markov decision processes (MDPs) with Borel state and action spaces, under discounted and average cost criteria. One ... -
Finite-state approximation of Markov decision processes
(Springer, 2018)In this chapter we study the finite-state approximation problem for computing near optimal policies for discrete-time MDPs with Borel state and action spaces, under discounted and average costs criteria. Even though existence ... -
Finite-state approximations to discounted and average cost constrained Markov decision processes
(IEEE, 2019-07)In this paper, we consider the finite-state approximation of a discrete-time constrained Markov decision process (MDP) under the discounted and average cost criteria. Using the linear programming formulation of the constrained ... -
First lattice calculation of charmed hadrons' electromagnetic form factors
(IOP Publishing, 2014)Electromagnetic form factors of D and D* mesons and Ξcc, Σc, Ωc and Ωcc baryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. ... -
First measurement of large area jet transverse momentum spectra in heavy-ion collisions
(Springer, 2021-05-31)Jet production in lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is studied with the CMS detector at the LHC, using PbPb and pp data samples corresponding to ... -

Frequently hypercyclic weighted backward shifts on spaces of real analytic functions
(TÜBİTAK, 2018)We study frequent hypercyclicity in the case of weighted backward shift operators acting on locally convex spaces of real analytic functions. We obtain certain conditions on frequent hypercyclicity and linear chaoticity ... -
The generalized fractional Benjamin–Bona–Mahony equation: Analytical and numerical results
(Elsevier, 2020-08)The generalized fractional Benjamin-Bona-Mahony (gfBBM) equation models the propagation of small amplitude long unidirectional waves in a nonlocally and nonlinearly elastic medium. The equation involves two fractional terms ... -
Hard color-singlet exchange in dijet events in proton-proton collisions at root √s = 13 TeV
(2021-08-26)Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at root s = 13 TeV. The signature is expected ... -
