Surface characterization driven CMP optimization for gallium nitride
(ECS, 2016)
Gallium nitride is a hard and chemically inert material demoting high material removal rates in the chemical mechanical planarization (CMP) applications. This paper focuses on the optimization of the process conditions to ...
EM-based joint time delay and channel estimation for cooperative communications
(IEEE, 2011)
In this paper, we study joint time delay and channel estimation for a cooperative communication system with amplify-and-forward (AF) relaying. The proposed joint estimator is based on Expectation-Maximization (EM) algorithm ...
Dilation and constriction of subjective time based on observed walking speed
(Frontiers Media S.A., 2018-12-21)
The physical properties of events are known to modulate perceived time. This study tested the effect of different quantitative (walking speed) and qualitative (walking-forward vs. walking-backward) features of observed ...
Aperture averaging in multiple-input single-output free-space optical systems
(SPIE, 2015-06)
Multiple-input single-output systems are employed in free-space optical links to mitigate the degrading effects of atmospheric turbulence. We formulate the power scintillation as a function of transmitter and receiver ...
Emerging optical wireless communications-advances and challenges
(IEEE, 2015-09)
New data services and applications are emerging continuously and enhancing the mobile broadband experience. The ability to cope with these varied and sophisticated services and applications will be a key success factor for ...
Ultraviolet communications for ground-to-air links
(IEEE, 2019)
Ultraviolet (UV) communication enables non-line-of-sight (NLOS) wireless connectivity through strong molecular and aerosol scattering. Due to their NLOS nature, UV links bring robustness to blockage or shadowing and relax ...
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
(IEEE, 2010)
In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study ...
Measurement of the top quark Yukawa coupling from t¯t kinematic distributions in the dilepton final state in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2020-11-30)
A measurement of the Higgs boson Yukawa coupling to the top quark is presented using proton-proton collision data at root s = 13 TeV, corresponding to an integrated luminosity of 137 fb(-1), recorded with the CMS detector. ...
Study of the B +→ J / ψ Λ ¯ p decay in proton-proton collisions at √s = 8 TeV
(Springer, 2019-12-12)
A study of the B +→ J / ψ Λ ¯ p decay using proton-proton collision data collected at s = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb−1, is presented. The ratio of branching ...
Search for natural supersymmetry in events with top quark pairs and photons in pp collisions at √s=8 TeV
(Springer Nature, 2018-03)
Results are presented from a search for natural gauge-mediated supersymmetry (SUSY) in a scenario in which the top squark is the lightest squark, the next-to-lightest SUSY particle is a bino-like neutralino, and the lightest ...
