提出了具有间断面的球形地球三维射线追踪的伪弯曲方法。该方法的基础是一阶近似3点扰动,同时曲线坐标中的斯奈尔定律应用到间断面上。我们通过与解析解和弯曲法结果的比较,证实了不同速度模型中伪弯曲方法射线追踪的计算精度和有效性。尽管有效性的改善是明显的,但它将随着间断面数量的增加而减小。尽管弯曲法精确,但在某些情况下亦可能是计算不稳定的。因此,伪弯曲法在射线自动计算方面还是可取的。

建立了壳内地震、板间地震、板内地震的峰值地动速度(PGV)和峰值地动位移(PGD)的长周期(5~30s)地震动预测方程(GMPE)。使用了剪切波速大于或等于2 000m/s的层间的kik-net井下台网台站强地震动数据。这些数据由日本及其周边的20次6≤MW≤9.1的地震构成,包括2011年的日本东北地震。在推导长周期地震动预测方程时运用了两阶段回归分析。尽管附加了诸如震源深度和地震类型这些尽量能够使回归曲线与数据保持一致的因素,但在双线性回归时于MW7.5处产生了弯曲。所建公式表明:壳内地震的长周期峰值地动速度和峰值地动位移要大于板间地震和板内地震。长周期峰值地动速度和峰值地动位移衰减系数随着震源深度的增加而增加。估计的矩震级符合观测的峰值地动速度和峰值地动位移在5~30s周期范围内的长周期地震动预测方程。得到了由kik-net井下台网台站加速度计记录的23次地震的震级估计,而且这一结果与全球矩心矩张量项目得到的矩震级一致。上述方法对于大地震的矩震级估计是有效的,如果能够获取震源区的信息,就能快速进行矩震级的估计。

通过反演研究2008年日本岩手—宫城内陆地震(M～6.9),说明了用1Hz全球定位系统(GPS)观测数据推导中强震(M6级)震源过程的能力。比较了此次地震采样率为1Hz的GPS观测波形,发现与强震仪记录波形有很好的一致性。由于震源区及其周围有足够多的GPS台站很好地记录到了地面运动,因而使我们仅仅采用1Hz的GPS观测数据就可进行波形反演。反演的结果与大地测量和强震仪数据联合反演的结果相当一致,如地震矩(Mw～6.9)、累积滑动量分布和破裂传播等。这种一致性证明,采样率为1Hz的GPS观测数据不仅能用来推导M6级中强震破裂过程的动态特征,而且能用来推导其持久(或静态)的滑动。

AIM To unravel relationships between gastrointestinal(GI)symptoms impairing quality of life(QOL)and clinical profiles of diabetes mellitus(DM)patients. METHODS We enrolled 134 outpatients with type 2 *** age was 64.7 years,mean body mass index was 24.7 RESULTS Lower abdominal symptoms were found to be more frequent than those affecting the upper *** duration and medications showed associations with GI *** identified differences in peak prevalences of the five ***(P=0.02vs 10-14 years)and total GI symptoms(P=0.01 and P=0.02 vs 5-9 years and 10-14 years,respectively)peaked at a diabetes duration of 15-19 ***(P=0.004)and postprandial fullness(P=0.03)tended to increase with disease *** and diarrhea showed bimodal peaks,with the first early and the second late(e.g.,P=0.03 at 15-19 years vs 10-14years for diarrhea)in the disease ***,GI symptoms showed clustering that reflected the region of the GI tract affected,i.e.,constipation and diarrhea had similar frequencies(P<0.0001). CONCLUSION Our study highlights the importance of questioning patients about QOL impairment due to abdominal symptoms,especially in the early and the late periods of diabetes.

Previously, we found 123 transcription factors（TFs） as candidate regulators of secondary cell wall（SCW）formation in rice by using phylogenetic and co-expression network analyses. Among them, we examined in this work the role of OsIDD_2, a zinc finger and indeterminate domain（IDD） family TF. Its overexpressors showed dwarfism, fragile leaves, and decreased lignin content, which are typical phenotypes of plants defective in SCW formation, whereas its knockout plants showed slightly increased lignin *** RNA-seq and quantitative reverse transcription polymerase chain reaction analyses confirmed that some lignin biosynthetic genes were downregulated in the OsIDD_2-overexpressing plants, and revealed the same case for other genes involved in cellulose synthesis and sucrose metabolism. The transient expression assay using rice protoplasts revealed that OsIDD_2 negatively regulates the transcription of genes involved in lignin biosynthesis, cinnamyl alcohol dehydrogenase 2 and 3（CAD_2 and 3）, and sucrose metabolism, sucrose synthase 5（SUS_5）, whereas an Alpha Screen assay, which can detect the interaction between TFs and their target DNA sequences, directly confirmed the interaction between OsIDD_2 and the target sequences located in the promoter regions of CAD_2 and CAD_3. Based on these observations, we conclude that OsIDD_2 is negatively involved in SCW formation and other biological events by downregulating its target genes.
