International Journal of Geosciences 2022年第10期13卷 882-904页

Bafia Group is part of the southernmost portion of the Central African Fold Belt (CAFB) in Cameroon. The geological feature of the group is characterized by the presence of metamorphic rocks in which tourmaline had been recognized among accessory minerals. In the present study, attention is focus on the tourmaline bearing quartzite to the southeast of Kombé II. Structure refinement shows that tourmaline is a Fe-dravite with the formula X(Na0.95[]0.05)Y(Mg2.39Fe0.61)Z(Al5.10Mg0.90)(BO3)3T[Si6O18](OH)3[(O,OH)0.88F0.12]. The Fe-dravite is hosted in a Ca-poor quartzite, which is made up, in addition to quartz and tourmaline, of biotite and muscovite. The structure of the dravites shows a low vacancy at the X site, which militates for a crystallization of the tourmaline at a high temperature > 750℃. This is in agreement with previous work which shows that the metamorphic peak in the associated biotite gneiss reaches 825℃. The R1 value of 1.24% means that the crystal structure of the tourmalines is of high quality. The genetical link between gold mineralization and tourmaline should stimulate exploration interest in the study area.

作物产量估测关系到人民生活质量和国家粮食安全问题,在田块尺度下及时准确估算产量,对于农事操作管理、收获、销售及种植计划制定均具有重要意义。选择地势起伏及空间差异较大的农田为研究区,利用低空无人机遥感平台搭载多光谱相机、热红外相机和RGB相机,同步获取小麦关键生育时期的无人机遥感影像,并提取光谱反射率、热红外温度和数字高程信息。首先统计不同地形特征下遥感参数和生长指标的空间变异情况,分析植被指数和温度参数与小麦产量的相关性,然后利用多元线性回归(multiple linear regression,MLR)、偏最小二乘回归(partial least squares regression,PLSR)、支持向量机回归(support vector machine regression,SVR)和随机森林回归(random forest regression,RFR)4种机器学习方法以单模态数据和多模态遥感信息融合2种方式进行建模,比较单模态数据和多模态数据融合的产量估测能力。结果表明,坡度是影响作物生长和产量的重要因子,3个生育期内,不同坡度等级下遥感参数差异明显,土壤含水量、植株含水量和地上部生物量与坡度的相关性均达显著水平,植被指数和温度参数与产量的相关性均达显著水平。依据与产量的相关性,筛选7个植被指数(NDVI、GNDVI、EVI2、OSAVI、SAVI、NDRE、WDRVI)和2个温度参数(NRCT、CTD)作为模型输入变量,对于单模态数据而言,对产量的估算效应为植被指数>温度参数,以灌浆期植被指数的RFR模型效果最好(R2=0.724,RMSE=614.72 kg hm^(-2),MAE=478.08 kg hm^(-2));对于双模态数据融合来说,在植被指数基础上融入冠层温度参数表现最好,开花期RFR模型效果进一步提高(R2=0.865,RMSE=440.73 kg hm^(-2),MAE=374.86 kg hm^(-2));在双模态数据基础上引入坡度信息进行三模态数据融合,其产量估算效果明显优于单模态和双模态数据融合,其中以开花期植被指数、温度参数和坡度信息融合的RFR估算效果最好(R2=0.893,RMSE=420.06 kg hm^(-2),MAE=352.69 kg hm^(-2)),模型验证效果较好(R2=0.892,RMSE=423.55 kg hm^(-2),MAE=334.43 kg hm^(-2))。可见,在本试验条件下通过引入地形因子,结合随机森林回归算法将多模态数据有效融合,可充分发挥不同遥感信息源之间互补协同作用,有效提高了产量估算模型的精度与稳定性,为作物生长监测及产量估算提供思路参考和方法支持。

矿物粉尘在当今气候研究中发挥着重要的作用.矿物粉尘气溶胶具有的发射性质使其直接影响着大气圈的辐射平衡.矿物粉尘也以多种间接方式积极参与了气候活动,其中包括成为云层凝聚中心来决定云盖层的规模和特征以及可能控制着遥远的营养贫瘠的大洋与大陆地区的原始生物生产力.尽管我们并不十分了解所有这些作用过程,但是过去矿物粉尘循环的重大动力作用会使人考虑到它是一个气候变化的重要反馈回路.在这个问题上,我们还不确定冰期时期矿物粉尘浓度的大量增加(正如在极地冰心中观察到的那样)是否仅局限于高纬度地区还是涵盖了大部分的大气圈.

Neural Regeneration Research 2013年第24期8卷 2290-2302页

In the last few years, there have been important new insights into the structural biology of G-protein coupled receptors. It is now known that allosteric binding sites are involved in the affinity and selec- tivity of ligands for G-protein coupled receptors, and that signaling by these receptors involves both G-protein dependent and independent pathways. The present review outlines the physiological and pharmacological implications of this perspective for the design of new drugs to treat disorders of the central nervous system. Specifically, new possibilities are explored in relation to allosteric and or- thosteric binding sites on dopamine receptors for the treatment of Parkinson＇s disease, and on muscarinic receptors for Alzheimer＇s disease. Future research can seek to identify ligands that can bind to more than one site on the same receptor, or simultaneously bind to two receptors and form a dimer. For example, the design of bivalent drugs that can reach homo/hetero-dimers of D2 dopa- mine receptor holds promise as a relevant therapeutic strategy for Parkinson＇s disease. Regarding the treatment of Alzheimer＇s disease, the design of dualsteric ligands for mono-oligomeric mus- carinic receptors could increase therapeutic effectiveness by generating potent compounds that could activate more than one signaling pathway.

Outpatient subcutaneous (s.c.) therapies are becoming more and more common in the treatment of different diseases. The effectiveness of community-pharmacy-based interventions in preventing problems that arise during s.c. self-injections of low-molecular-weight heparins (LMWH) is unknown. Our objective was to provide a standard operating procedure (SOP) for community pharmacists and to compare pharmaceutical vs. standard care in both clinical and daily life settings. We hypothesized that: pharmaceutical care results in improved adherence, safety, and satisfaction, and in fewer complications;the interventions used are feasible in daily life;and the results achieved in clinical and daily life settings are comparable. In the clinical setting (randomized controlled trial), patients were recruited sequentially in hospital wards;in the daily life setting (quasi-experimental design with a comparison group), recruitment took place in community pharmacies by pharmacists and trained master students during their internship. Interventions were offered according to patient needs. Data were collected by means of a monitored self-injection at home and structured questionnaire-based telephone interviews at the beginning and the end of the LMWH treatment. The main outcome measures were: scores to assess patient’s skills;syringe count to assess adherence;and frequency, effectiveness, and patient’s assessment of received interventions. The results show a median age of the 139 patients of 54 years. Interventions resulted in improved application quality (p p = 0.03). Oral instructions were pivotal for improving patients’ application quality. We found no significant score differences between the intervention groups in the clinical and daily life settings. Patients’ baseline skills were high, with the lowest score being 0.86 (score range ?2.00 to +2.00). Adherence rate was high (95.8%). In conclusion, our SOP for pharmacist interventions was of good quality, adequate, appreciated, and feas
