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 ...
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.. ...
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 ...
Efficient Election Campaign Optimization Using Integer Programming
(Omniascience, 2018)
Purpose: Political parties spend significant amounts of resources during their election campaigns, which are usually designed in a sub-optimal and informal way. This study aims to provide a mathematical framework for ...
Luminosity measurements for the R scan experiment at BESIII
(Chinese Physical, 2017)
By analyzing the large-angle Bhabha scattering events e(+)e(-) -> (gamma)e(+)e(-) and diphoton events e(+)e(-) -> (gamma)gamma gamma for the data sets collected at center-of-mass (c.m.) energies between 2.2324 and 4.5900 ...
OPCOMITS: Developing an Adaptive and Intelligent Web Based Educational System Based on Concept Map Model
(Wiley, 2016)
Concept map model is a method that creates domain model by identifying the relationship between concepts in course contents. This study presents an adaptive intelligent web based learning system called OPCOMITS (Object ...
Precision Measurement of the Branching Fractions of eta ' Decays
(Amer Physic Soc., 2019-04-09)
Based on a sample of (1310.6 +/- 7.0) x 10(6)J/psi events collected with the BESIII detector, we present measurements of J=. and. 0 absolute branching fractions using the process J/psi -> gamma eta'. By analyzing events ...
Overlapping clusters algorithm in ad hoc networks
(IEEE, 2010)
Clustering allows efficient data routing and multi-hop communication among the nodes. In this paper, we propose Overlapping Clusters Algorithm (OCA) for mobile ad hoc networks. The goal of OCA is to achieve network reliability ...
Urban design factors involved in the aesthetic assessment of newly built environments and their incorporation into legislation: The case of Istanbul
(Urban Planning Inst. Republic Slovenia, 2018-12)
Newly built environments in cities whose features have changed due to neoliberal policies and priorities have often been criticized for their lack of aesthetic qualities. This criticism has made the aesthetic assessment ...
Measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu)
(Elsevier Science, 2017)
We report the first measurement of the absolute branching fraction for Lambda(+)(c) -> Lambda mu(+)nu(mu).This measurement is based on a sample of e+e(-) annihilation data produced at a center-of-mass energy root s = 4.6 ...
