Trust evaluation model based on improved D-S evidence theory [PDF]

open access: yesTongxin xuebao, 2013
The existing trust evidence models cannot deal with malicious attacks in the distributed net quickly and effectively, and are lack of a trust normalization method that can measure relationship described by a triple set, so a trust model based on the ...

First evidence for the annihilation decay mode $B^{+} \to D_{s}^{+} \phi$ [PDF]

open access: yes, 2012
Evidence for the hadronic annihilation decay mode B+→D+sϕ is found with greater than 3σ significance. The branching fraction and CP asymmetry are measured to be B(B+→D+sϕ)=(1.87+1.25−0.73(stat)±0.19(syst)±0.32(norm))×10−6,ACP(B+→D+sϕ)=−0.01±0.41(stat)±0 ...

Feature Selection for Interval-Valued Data Based on D-S Evidence Theory

open access: yesIEEE Access, 2021
Feature selection is one basic and critical technology for data mining, especially in current “big data era”. Rough set theory (RST) is sensitive to noise in feature selection due to the strict condition of equivalence relation.

s±+d wave multiband Eliashberg theory for the iron pnictides [PDF]

open access: yes, 2022
We calculated the critical temperature in the framework of s± + d-wave multiband Eliashberg theory. We have solved these equations numerically to see at what values of the input parameters there is a solution with a non-zero critical temperature and ...
