Pseudoscalar-meson octet-baryon coupling constants from two-flavor lattice QCD
(Elsevier, 2010-04-01)We evaluate the pseudoscalar-meson octet-baryon coupling constants and the corresponding axial charges in eight channels (πNN, πΣΣ, πΛΣ, KΛN, KΣN, πΞΞ, KΛΞ and KΣΞ) in lattice QCD with two flavors of dynamical quarks. The ... -
Pseudoscalar-meson-octet-baryon coupling constants in two-flavor lattice QCD
(American Physical Society, 2009-04-01)We evaluate the πΝΝ, π∑∑, πΛ∑, KΛN and K∑N coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters representing the SU(3)-flavor symmetry are computed ... -
Pseudothermal light based quantum random number generator
(IEEE, 2020-10-22)The importance of quantum random number generators (QRNGs) is increasing day by day. An important aspect of any QRNG is the speed of the system. This paper introduces the theory behind a pseudothermal light based QRNG. ... -

Q-learning in regularized mean-field games
(Springer, 2023-03)In this paper, we introduce a regularized mean-field game and study learning of this game under an infinite-horizon discounted reward function. Regularization is introduced by adding a strongly concave regularization ... -
QCD coupling constants and VDM
(AIP, 2012)QCD sum rules for coupling constants of vector mesons with baryons are constructed.The corresponding QCD sum rules for electric charges and magnetic moments are also derived and with the use of vector-meson-dominance model ... -
QCD sum rules for the coupling constants of vector mesons to octet baryons
(Springer Science+Business Media, 2013-05)The QCD sum rules on the light cone proposed by Wang for the coupling constants of the ρ meson are generalized to the vector mesons ω and φ and all octet baryons, the Λ-hyperon included. A comparison with other results is given. -
QoE-aware bandwidth broker for HTTP adaptive streaming flows in an SDN-enabled HFC network
(IEEE, 2018-06)This paper proposes a software defined networking based bandwidth broker solution for improving viewer experience for any type of content delivered to any type of consumer device using HTTP adaptive streaming (HAS) in a ... -
Quality upshifting with auxiliary I-Frame splicing
(IEEE, 2023)This paper introduces the Auxiliary I-Frame Splicing method to reduce bandwidth waste in adaptive streaming. This method involves fetching a high-quality I-frame and splicing it into the already downloaded low-quality ... -
Quantum signatures in a quadratic optomechanical heat engine with an atom in a tapered trap
(Optica Publishing Group, 2022-12)We investigate how quantum signatures can emerge in a single atom heat engine consisting of an atom confined in a tapered trap and subjected to hot and cold thermal reservoirs. A similar system was realized experimentally ... -
Quantum spatial modulation of optical channels: Quantum boosting in spectral efficiency
(IEEE, 2019-11)Spatial modulation (SM) improves spectral efficiency (SE) by creating the constellation of active optical antenna indices. However, quantum properties of light are not exploited to improve the SE. In this letter, multi-plane ... -
Quasi-resonant circuitry to improve heat transfer and efficiency in induction cooker
(IEEE, 2021)This paper proposes a dual-mode coil structure for induction cookers using a single switching element quasi-resonant circuit and examines its effect on heating performance. In an induction cooker, the material base to be ... -
Quasistatic nonlinear viscoelasticity and gradient flows
(Springer Science+Business Media, 2014)We consider the equation of motion for one-dimensional nonlinear viscoelasticity of strain-rate type under the assumption that the stored-energy function is λ-convex, which allows for solid phase transformations. We formulate ... -
Quaternion capsule networks
(IEEE, 2021)Capsules are grouping of neurons that allow to represent sophisticated information of a visual entity such as pose and features. In the view of this property, Capsule Networks outperform CNNs in challenging tasks like ... -
Quickly starting media streams using QUIC
(Association for Computing Machinery, Inc, 2018-06-12)Originally proposed by Google, QUIC is a low-latency transport protocol currently being developed and specified in the IETF. QUIC's low-latency, improved congestion control, multiplexing features are promising and may help ... -
