Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ [PDF]

open access: yes, 2012
The ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is

Analysis of Gutenberg-Richter b-value and mmax [PDF]

open access: yes, 2021
When we analyzed the Gutenberg-Richter distribution function in our earlier works, we assumed that the b-value is positive.  Using generalized estimators, we found that in some cases the b-value can be also negative.

基于经验模型分析2018年2月台湾花莲地震序列特征及其前震的成因机制

open access: yesDizhen xuebao, 2020
利用地震学的三个经典经验模型(古登堡-里克特定律、修正的大森定律和巴特定律)和描述前震活动的Dieterich前震模型对2018年2月中国台湾花莲地震序列的特征进行了分析。将该地震序列分为ML5.5前震序列、ML5.5余震序列和ML6.0余震序列等3段子序列进行研究,结果显示:利用古登堡-里克特定律得到的ML5.5余震序列和ML6.0余震序列的b值近似为1,ML5.5前震序列的b值近似为0.5;利用修正的大森定律得到的ML5.5余震序列和ML6.0余震序列的p值近似为0.9;利用修正的巴特定律得出ML5.

Correcting the Gutenberg-Richter b-value for Effects of Rounding and Noise [PDF]

open access: yes, 2015
"The effects of magnitude rounding and of the presence of noise in the rounded magnitudes on the estimation of the Gutenberg–Richter b-value are explored, and the ways to correct for these effects are proposed.

Spatial Temporal Condition of Recent Seismicity In The Northern Part of Sumatra

open access: yesElkawnie: Journal of Islamic Science and Technology, 2021
: The condition of stress and recent seismicity in the seismic-prone area can be statistically analyzed with the Gutenberg-Richter relation (Log N = a-bM).

Variability of the b value in the Gutenberg–Richter distribution [PDF]

open access: yesGeophysical Journal International, 2014
The b value of the Gutenberg - Richter distribution is estimated as a function of a threshold magnitude m_th and it is found to depend on m_th for magnitudes larger than the completeness magnitude m_c. We identify a magnitude interval [m_c;m_m] where b is a decreasing function of m_th followed by a regime of increasing b for large magnitudes. This is a
