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 ...
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 ...
Observation of the decays chi(cJ) -> phi phi eta
(Amer Physical Soc., 2020)
Using a data sample of (448.1 +/- 2.9) x 10( )(6)psi(3686) decays collected by the BESIII detector at the Beijing Electron Positron Collider (BEPCII), we observe the decays chi(cJ) -> phi phi eta (J = 0, 1, 2), where the ...
Observation of the Y(4220) and Y(4390) in the process e(+)e(-) -> eta J/psi
(Amer Physical Soc., 2020)
The cross sections of the process e(+)e(-) -> eta J/psi lip at center-of-mass energies (root s) between 3.81 and 4.60 GeV are measured with high precision by using data samples collected with the BESIII detector operating ...
Improved model-independent determination of the strong-phase difference between D-0 and (D)over-bar(0) -> (KS,LK+)-K-0 K- decays
(Amer Physical Soc., 2020)
We present a measurement of the strong-phase difference between D-0 and (D) over bar (0) -> (KS,LK+K-)-K-0 decays, performed through a study of quantum-entangled pairs of charm mesons. The measurement exploits a data sample ...
Dataset on Catal's reagent: Sensitive detection of iron (II) sulfate using spectrophotometry
(Elsevier, 2020)
Catal's reagent is characterized by spectroscopic methods such as fourier-transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), ultraviolet (UV)-visible spectrophotometry. ...
Determination of Strong-Phase Parameters in D -> K-S,L(0)pi(+)pi(-)
(Amer Physical Soc., 2020)
We report the most precise measurements to date of the strong-phase parameters between D-0 and (D) over bar (0) decays to K-S,L(0)pi(+)pi(-) using a sample of 2.93 fb(-1) of e(+) e(-) annihilation data collected at a ...
Search for the semileptonic decay D0(+) -> b(1) (1235)(-(0))e(+)v(e)
(Physical Review D., 2020)
Using 2.93 fb-1 of e(+)e(-) data collected at a center-of-mass energy root s = 3.773 GeV with the BESIII detector operating at the BEPCII collider, we search for the semileptonic D0(+) decays into a b(1)(1235)(-(0)) ...
Partial wave analysis of psi(3686) -> K+ K- eta
(Amer Physical Soc., 2020)
Using a sample of (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector, we perform the first partial wave analysis of psi(3686) -> K+K- eta. In addition to the well established states, phi(1020), ...
Study of Open-Charm Decays and Radiative Transitions of the X(3872)
(Amer Physical Soc., 2020)
The processes X(3872) -> D*(0)(D) over bar (0) + c.c., gamma J/psi, gamma psi(2S), and gamma D+D- are searched for in a 9.0 fb(-1) data sample collected at center-of-mass energies between 4.178 and 4.278 GeV with the BESIII ...
