Direct Measurement of the Branching Fractions B(psi(3686) -> J/psi X) and B(psi(3770) -> J/psi X), and Observation of the State R(3760) in e(+)e(-) -> J/psi X
(Amer Physical Soc., 2021)
We report a measurement of the observed cross sections of e(+)e(-) -> J/psi X based on 3.21 fb(-1) of data accumulated at energies from 3.645 to 3.891 GeV with the BESIII detector operated at the BEPCII collider. In analysis ...
Oscillating Features in The Electromagnetic Structure of The Neutron
(Nature Research, 2021)
The complicated structure of the neutron cannot be calculated using first-principles calculations due to the large colour charge of quarks and the self-interaction of gluons. Its simplest structure observables are the ...
Maximal normal subgroups of the automorphism groups of free nilpotent groups
(Kossuth Lajos Tudomanyegyetem, 2020)
We prove that the subgroup of all IA-automorphisms of the automorphism group Aut(N) of a free nilpotent group N of infinite rank is normality-small. As a consequence, every maximal normal subgroup of the group Aut(N) is a ...
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 ...
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 ...
