Observation of a Resonant Structure in e(+)e(-)-> Omega Eta and Another in e(+)e(-)-> Omega pi(0) at center-of-mass Energies Between 2.00 and 3.08 GeV
(Elsevier, 2021)
Born cross sections for the processes e(+)e(-) -> omega eta and e(+)e(-) -> omega pi(0) have been determined for centerof-mass energies between 2.00 and 3.08GeVwith the BESIII detector at the BEPCII collider. The results ...
Life Experiences of Mothers of Children with an Intellectual Disability: A Qualitative Study
(Taylor & Francis, 2018)
Introduction: Mothers of intellectually disabled children face several psychological problems. Qualitative studies use a process that can reveal truthful perceptions and help mothers express their emotions about their ...
Single machine scheduling problems under position-dependent fuzzy learning effect with fuzzy processing times
(Elsevier Science, 2017)
In this paper, we consider single machine scheduling problems under position-dependent fuzzy learning effect with fuzzy processing times. We study three objectives which are to minimize makespan, total completion time and ...
Spectrum Measurement of Variable Irradiance Controlled LED-Based Solar Simulator
(Int Journal Renewable Energy Research, 2020)
Efficiency of photovoltaic devices are based on testing all equipment and systems used to produce devices in a healthy way, from electrical and optical points of view. Considering that photovoltaic devices which enable the ...
Study of decay dynamics and CP asymmetry in D+ ? KL0 e+?e decay
(American Physical Society, 2015)
Using 2.92 fb-1 of electron-positron annihilation data collected at s=3.773 GeV with the BESIII detector, we obtain the first measurements of the absolute branching fraction B(D+?KL0e+?e)=(4.481±0.027(stat)±0.103(sys))% ...
Temperature dependence of magnetic and thermal properties of chiral HyFe and HyMn close to phase transitions by using the Landau mean field model
(Elsevier Science, 2019)
Magnetic and thermal properties of chiral metal formate frameworks (MOFs) of NH2NH3M(HCOO)(3), M = Fe, Mn, namely, HyFe and HyMn are investigated close to phase transitions by using Landau phenomenological model. By expanding ...
Evaluation of enterprise investment attractiveness under circumstances of economic development
(SCIENDO, 2020)
This article introduces a step-by-step methodology for evaluating an enterprise's investment attractiveness in the context of economic development, using appropriate valuation parameters at macro, meso and micro levels. A ...
