The fraction f of ${\mathit{D}}^{0}$ semimuonic decays which occur through the K\ensuremath{\mu}\ensuremath{\nu} mode has been measured in a hybrid emulsion spectrometer. Analysis 124 ${\mathit{D}}^{0}$-decay candidates gives f=0.32\ifmmode\pm\else\textpm\fi{}0.05 (stat) \ifmmode\pm\else\textpm\fi{}0.05 (syst). From this measurement and existing data on semileptonic branching ratio lifetime, we obtain...
One way to improve the efficiency of mine search, compared with a complete coverage algorithm, is direct search based on spatial distribution minefield. The key for success this probabilistic approach efficiently extract minefield during process search. In our research, we assume that follows regular pattern, which belongs family known patterns. A Bayesian pattern extraction developed underlying algorithm performs well in its ability catch "actual" situation where placement and detector...
One way to improve the efficiency of mine search, compared with a complete coverage algorithm, is direct search based on spatial pattern minefield. This paper extends our original statistical approach (2001) identify regular minefield at beginning searching process. The extracted parameters are used build probability distribution map configuration then can be guide for more mines efficiently. new efficiently capture systematic and accumulated random departure actual locations from grid...
Abstract Evaluating the quality of air traffic control operations is crucial for enhancing airspace management. Thus, this paper proposes a data mining approach conducting comprehensive assessment operation (COQ) in increasingly complex environments. First, authors establish COQ evaluation index system that combines both subjective and objective measures. Key parameters are determined using wavelet filtering interval estimation techniques on basis results. Second, apply an entropy‐weighted...
We explore the big-bang nucleosynthesis (BBN) constraint on heavy neutrino that is a mixture of gauge singlet fermion and active neutrinos in Standard Model. work minimal model with only two parameters, mass $m_4$ mixing parameter $|U_{a4}|^2$, where $a=e$, $\mu$, or $\tau$ stands for flavor. show both early universe production mechanism decay products are determined by little room further assumptions. This predictivity allows us to present portrait entire BBN excluded space. Our analysis...
We report on the characteristics of 9 bb pair events produced by a 600 GeV/c π- beam and detected in hybrid emulsion spectrometer Fermilab experiment E653. The measured lifetimes for samples 12 neutral 6 charged beauty hadrons are τb0 = 0.81+0.34+0.08-0.22-0.02 ps, τb± 3.84+2.73+0.80-1.36-0.16 ps.
