Observation of the dalitz decay ?’??e+e?
(American Physical Society, 2015)
We report the first observation of the Dalitz decay ?’??e+e?, based on a data sample of 1.31 billion J/? events collected with the BESIII detector. The ?’ mesons are produced via the J/????’ decay process. The ratio ...
Optimization of the finned double-pipe heat exchanger using nanofluids as working fluids
(Springer, 2020)
The heat exchanger pipe diameter has a significant effect on the flow characteristics as well as on the initial investment, operation and overall cost. Increasing fin dimensions increases the annulus hydraulic diameters. ...
Measurements of ? (3686) ?k- ? ? ¯ ++ c. c. and ? (3686) ??K- ? ? ¯ ++ c. c.
(American Physical Society, 2015)
Using a sample of 1.06×108?(3686) events produced in e+e- collisions at s=3.686 GeV and collected with the BESIII detector at the BEPCII collider, we present studies of the decays ?(3686)?K-??¯++c.c. and ?(3686)??K-??¯++c.c.. ...
A Numerical Analysis of Convection Heat Transfer and Friction Factor for Oscillating Corrugated Channel Flows
(Taylor and Francis Ltd., 2021)
The aim of this article is to understand numerically the flow and heat transfer characteristics under oscillating flow conditions for periodically corrugated wavy channel. For the same channel, under steady-state flow ...
Observation of the isospin-violating decay J /? ???0f0 (980)
(American Physical Society, 2015)
Using a sample of 1.31×109 J/? events collected with the BESIII detector at the BEPCII collider, the decays J/????+?-?0 and J/????0?0?0 are investigated. The isospin-violating decay J/????0f0(980) with f0(980)??? is observed ...
Search for the rare decay eta ' -> pi(0)pi(0)pi(0)pi(0) at BESIII
(Amer Physical Soc., 2020)
Using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, we perform a search for the rare decay if eta' -> 4 pi(0) via J/psi -> gamma eta'. No significant eta' signal is observed in the 4 pi(0) ...
Long-Term Outcomes of a New Minimally Invasive Approach in Chiari Type 1 and 1.5 Malformations: Technical Note and Preliminary Results
(Elsevier, 2018-07)
BACKGROUND: The treatment options for patients with Chiarimalformation type 1 (CM1) and Chiarimalformation type 1.5 (CM1.5) have not yet been standardized. In these malformations, the main factors include obstruction at ...
A new Fuzzy C-Means and AHP-based three-phased approach for multiple criteria ABC inventory classification
(Springer, 2020)
ABC analysis is an efficient and easy-to-use methodology to classify inventory based on a single or multi-criteria basis that may consist of thousands of items. The first study by Dickie (Fact Manag Maint 109(7):92-94, ...
The long-term impacts of preterm birth and associated morbidities on bone health in preschool children: a prospective cross-sectional study from Turkey
(Taylor & Francis, 2020)
Objective: To evaluate the impact of preterm birth on bone health in preschool children. Methods: A total of 166 preschool children (aged 7-8 years) born preterm (n = 86, <37-week gestation) and at term (n = 80, >= 37 weeks ...
Variable antenna-space shift keying for high spectral efficiency in exponentially correlated channels
(Wiley, 2017)
the case of correlated channels. Then, to reduce the correlation effect, a novel antenna codeword construction method that minimizes the pairwise error probability is introduced for exponentially correlated channels. ...
