Search for D0 ??? and improved measurement of the branching fraction for D0 ??0?0
(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 report the results of a search for the flavor-changing neutral current process D0 ??? using a double-tag ...
Searches for isospin-violating transitions χc0,2 → π0ηc
(American Physical Society, 2015)
We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2 → π0ηc. The measurements are performed using 106×106ψ(3686) events accumulated with the BESIII detector at ...
Observation of a Neutral Charmoniumlike State Zc (4025)0 in e+e- → (D∗ D ¯ ∗)0π0
(American Physical Society, 2015)
We report a study of the process e+e-→(D∗D¯∗)0π0 using e+e- collision data samples with integrated luminosities of 1092 pb-1 at s=4.23 GeV and 826 pb-1 at s=4.26 GeV collected with the BESIII detector at the BEPCII storage ...
The determination of short circuits and grounding faults in electric power systems using time-frequency analysis
(UNIV CAPE TOWN, ENERGY RES CENTRE, 2015)
In order to ensure that electrical energy reaches consumers uninterrupted, researchers constantly try to improve power transmission lines. To realize this improvement, probable faults should be analysed through every known ...
Nano-Bioceramic Synthesis from Tropical Sea Snail Shells (Tiger Cowrie - Cypraea Tigris) with Simple Chemical Treatment
(POLISH ACAD SCIENCES INST PHYSICS, 2015)
In this study several bioceramic materials (i.e. hydroxyapatite, whitlockite) were prepared by using chemical synthesis method from sea snail shells (Tiger Cowrie - Cypraea Tigris), originated from Pacific Ocean. Maxine ...
