摘要：
Previous studies on the neural basis of insight reflected weak consistency except for the anterior cingulate cortex. The present work adopted the semantic and homophonic punny riddle to explore the uniformity and nonuniformity of neural activities correlated to different insight problem solving. Results showed that in the early period of insight solving, the semantic and homophonic punny riddles induced a common N350-500 over the central scalp. However, during -400 to 0 ms before the riddles were solved, the semantic punny riddles induced a positive event-related potential (ERP) deflection over the temporal cortex for retrieving the extensive semantic information, while the homophonic punny riddles induced a positive ERP deflection over the temporal cortex and a negative one in the left frontal cortex which might reflect the semantic and phonological information processing respectively. Our study indicated that different insight problem solving should have the same cognitive process of detecting cognitive conflicts, but have different ways to solve the conflicts. (C) 2014 IBRO.

摘要：
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb(-1) collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Xi(b)(0) --> Xi(c)(+)pi(-), Xi(c)(+)) --> pK(-)pi(+) signal decays are reconstructed. From this sample, the first measurement of the Xi(b)(0) baryon lifetime is made, relative to that of the Lambda(b)(0) baryon. The mass differences M(Xi(b)(0))-M(Lambda(b)(0)) and M(Xi(c)(+))-M(Lambda(c)(+)) are also measured with precision more than 4 times better than the current world averages. The resulting values are tau(Xi(b)(0))/tau(Lambda)(b)(0)) = 1.006 +/- 0.018 +/- 0.010,M(Xi(b)(0))-M(Lambda(b)(0)) = 172.44 +/- 0.39 +/- 0.17 MeV/c(2),M(Xi(c)(+))-M(Lambda(c)(+)) = 181.51 +/- 0.14 +/- 0.10 MeV/c(2),where the first uncertainty is statistical and the second is systematic. The relative rate of Xi(b)(0) to Lambda(b)(0) baryon production is measured to be f(Xi)(b)(0))/f(Lambda)(b)(0))B(Xi(b)(0) --> Xi(c)(+)pi(-))/B(Lambda(b)(0) --> Lambda(c)(+)pi(-))B(Xi(c)(+) --> pK(-)pi(+))/B(Lambda(c)(+) --> pK(-)}pi(+)) = (1.88 +/- 0.04 +/- 0.03) x 10(-2),where the first factor is the ratio of fragmentation fractions, b --> Xi(b)(0) relative to b --> Lambda(b)(0). Relative production rates as functions of transverse momentum and pseudorapidity are also presented.
