OBJECTIVE： To identify global research trends in neuroimaging diagnosis for cerebral infarction using a bibliometric analysis of the Web of Science. DATA RETRIEVAL： We performed a bibliometric analysis of data retrieval for neuroimaging diagnosis for cerebral infarction containing the key words ＂CT, magnetic resonance imaging, MRI, transcranial Doppler, transvaginal color Doppler, digital subtraction angiography, and cerebral infarction＂ using the Web of Science. SELECTION CRITERIA： Inclusion criteria were：（a） peer-reviewed articles on neuroimaging diagnosis for cerebral infarction which were published and indexed in the Web of Science; （b） original research articles and reviews; and （c） publication between 2004-2011. Exclusion criteria were：（a） articles that required manual searching or telephone access; and （b） corrected papers or book chapters. MAIN OUTCOME MEASURES：（1）Annual publication output; （2） distribution according to country; （3） distribution according to institution; （4） top cited publications; （5） distribution according to journals; and （6） comparison of study results on neuroimaging diagnosis for cerebral infarction. RESULTS： Imaging has become the predominant method used in diagnosing cerebral infarction. The most frequently used clinical imaging methods were digital subtraction angiography, CT, MRI, and transcranial color Doppler examination. Digital subtraction angiography is used as the gold standard. However, it is a costly and time-consuming invasive diagnosis that requires some radiation exposure, and is poorly accepted by patients. As such, it is mostly adopted in interventional therapy in the clinic. CT is now accepted as a rapid, simple, and reliable non-invasive method for use in diagnosis of cerebrovascular disease and preoperative appraisal. Ultrasonic Doppler can be used to reflect the hardness of the vascular wall and the nature of the plaque more clearly than CT and MRI. CONCLUSION： At present, there is no unified standard of classif

Becoming a mother is one of the most monumental experiences in a woman's lifetime. Women typically bear the primary caregiving responsibility for their infants, and they undergo numerous changes both mentally and physically, including behavioral, emotional, and hormonal changes, during the postpartum period. Studies have indicated that hormonal, experiential, and temporal factors significantly regulate emotional and cognitive brain functions during the postpartum period [1]. The determination of the neural basis of a maternal brain is critically important for understanding mother-infant attachments and thus perpetuating the human species. Until recently, limited investigations of the neuroanatomical and functional status of mothers have contributed to understanding the processing of maternal behaviors.

Understanding the neural basis underlying Internet gaming disorder(IGD) is essential for the diagnosis and treatment of this type of behavioral addiction. On the interactions between different brain regions involving in IGD, most of the current works using resting-state functional connectivity(rsFC) analysis to examine intrinsic brain network related to IGD. Aberrant rsFC of the default mode network(DMN) has been reported in individuals with IGD. A majority of studies suggested that the IGD demonstrated decreased rsFC between DMN-related regions, when comparing with healthy control. The question on the role of DMN plays in addiction has been widely discussed, as reFC provides us a good way to explore it. However, traditional rsFC evaluates pearson correlations among regions of interest(ROI) based on time series. This analytical approach could not answer questions about causal or directed connectivity among ROIs. Here we employed spectral dynamic causal modeling(spDCM) to explore this issue. The spDCM is an analytic technique that is modeled at the neuronal level. Therefore, it has the capacity to prompt the directional connectivity(effective connectivity) among functionally-related brain areas, compared with rsFC. In the current study, our main goal is to explore the effective connectivity within DMN network in IGD, which is the most active network in resting-state. Plenty of researches have revealed that the core regions of the DMN could also be observe aberrant changes in resting-state studies using IGD. we collected resting-state fMRI data from sizable samples(64 IGD and 63 recreational Internet game users, RGU). It must be said that the RGU had more gaming experience and longer game duration than the general control group but do not lose control of game, Which could overcome the limitations of previous studies using low frequent game players as controls. 4 regions within default mode network(medial prefrontal cortex, mPFC;posterior cingulate cortex, PCC;bilatera

基于东江流域博罗站月径流数据,采用游程理论提取水文干旱事件.选用Meta-Gaussian Copula函数,统计模拟水文干旱指标的多变量联合分布.采用Kendall联合重现期和最大可能权函数,设计给定联合超越重现期的水文干旱指标组合值,并定量评估水库径流调节作用对水文干旱多变量联合特征的影响.结果表明:东江流域水文干旱历时、强度和峰值的统计优选分布均为韦布尔分布.干旱指标之间具有较高的正相关性,Meta-Gaussian Copula能够很好地模拟水文干旱指标两变量和三变量联合分布.基于任意两个变量联合设计和三变量联合设计,干旱指标设计组合值位于同频位置附近,且同一个干旱指标设计值在不同变量组合之间差别较小.水库径流调节作用对于缓解东江流域水文干旱效果明显,同一组干旱指标的多变量联合超越重现期在水库影响下明显变大.联合超越重现期越小,水库对联合设计值的影响程度越大.根据目前水库运行模式,若要满足河道内最小管理流量目标,联合超越重现期10 a一遇的干旱历时、强度和峰值依然达到了约3.89~4.04月、7.20~7.97亿m3和2.99~3.12亿m3.

Reported here is an iridium-catalyzed enantio-divergent C（sp3）–H borylation of α-gem-dimethyl groups of trifluoromethyl ketone-derived hydrazones to construct a series of acyclic all-carbon quaternary stereocenters with a high level of chiral induction. Two different chiral bidentate boryl ligands from a common chiral source not only can switch the enantioselectivity but also are complementary in terms of the substrate scope.
