Observation of the doubly radiative decay eta ' -> gamma gamma pi(0)
(Amer Physical Soc., 2017)
Based on a sample of 1.31 billion J/psi events collected with the BESIII detector, we report the study of the doubly radiative decay eta' -> gamma gamma pi(0) for the first time, where the eta' meson is produced via the ...
HEEL: A new clustering method to improve wireless sensor network lifetime
(Inst Engineering Technology, 2020)
In wireless sensor networks, some resources such as memory and energy are limited. In recent years, there has been an increasing interest in improving network lifetime. Node energy plays an important role in the network ...
Branching fraction measurements of psi (3686) -> gamma chi(cJ)
(Amer Physical Soc., 2017)
Using a sample of 106 million psi(3686) decays, the branching fractions of psi(3686) -> gamma chi(c0), psi(3686) -> gamma chi(c1), and psi(3686) -> gamma chi(c2) are measured with improved precision to be (9.389 +/- 0.014 ...
Study of the Decay D-s(+) -> pi(+) pi(+) pi(-)eta and Observation of the W-annihilation Decay D-s(+) -> a(0)(980)(+)rho(0)
(Amer Physical Soc., 2021)
The decay D-s(+) -> pi(+) pi(+) pi(-)eta is observed for the first time, using e(+)e(-) collision data corresponding to an integrated luminosity of 6.32 fb(-1), collected by the BESIII detector at center-of-mass energies ...
Study of e(+)e(-) -> 2(p(p)over-bar) at center-of-mass Energies Between 4.0 and 4.6 GeV
(Amer Physical Soc., 2021)
Using data taken at 23 center-of-mass energies between 4.0 and 4.6 GeV with the BESIII detector at the Beijing Electron Positron Collider and with a total integrated luminosity of approximately 15 fb(-1), the process ...
Investigation of Microhardness Properties of the Multi-Walled Carbon Nanotube Additive Mgb2 Structure By Using The Vickers Method
(Elsevier, 2021)
In this study, the effect of multi-walled carbon nanotube doping to MgB2 compound on microhardness properties of MgB2 was investigated by using solid-state reaction method. The amount of multi-walled carbon nanotubes was ...
Finite-element analysis of shear tests on masonry triplets
(Ice Publishing, 2020)
The goal of this study is to develop a computational model for analyzing triplet specimens under shear loading. In order to simulate realistically the stiffness degradation and inelastic deformability during shear failure ...
Hybrid Algorithms Based On Combining Reinforcement Learning And Metaheuristic Methods To Solve Global Optimization Problems
(Elsevier, 2021)
This paper introduces three hybrid algorithms that help in solving global optimization problems using reinforcement learning along with metaheuristic methods. Using the algorithms presented, the search agents try to find ...
Low Dynamic Range Histogram Equalization (LDR-HE) Via Quantized Haar Wavelet Transform
(Springer, 2021)
Conventional contrast enhancement methods stretch histogram bins to provide a uniform distribution. However, they also stretch the existing natural noises which cause abnormal distributions and annoying artifacts. Histogram ...
Search for the Rare Semi-leptonic Decay J/psi -> D(-)e(+)nu(e) + c.c.
(Springer, 2021)
Using 10.1 x 10(9)J/ events produced by the Beijing Electron Positron Collider (BEPCII) at a center-of-mass energy s = 3.097 GeV and collected with the BESIII detector, we present a search for the rare semi-leptonic decay ...
