Precision measurements of the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+) Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV
(Amer Physic Soc., 2019-04-11)
Using data samples collected by the BESIII detector operating at the BEPCII storage ring, we measure the e(+)e(-) -> (KSK +/-)-K-0 pi(-/+ )Born cross sections at center-of-mass energies between 3.8 and 4.6 GeV, corresponding ...
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 ...
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))% ...
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 ...

Using (1310.6 +/- 7.0) x 10(6) J/psi events acquired with the BESIII detector at the BEPCII storage rings, the decay eta' -> pi(+)pi(-)mu(+)mu(-) is observed for the first time with a significance of 8 sigma via the process ...
Cross-linkable epoxidized maleinated castor oil : a renewable resin alternative to unsaturated polyesters
(Hindawi Publishing, 2016)
As an alternative resin to conventional synthetic unsaturated polyesters (UPEs), epoxidized maleinated castor oil (EMACO) was synthesized in two steps. For this purpose, castor oil was reacted with maleic anhydride at 70° ...
