Taste interaction is a well-known phenomenon in sensory stodies,but how to quantify the magnitode of the effect of one tastant on other taste attribute(s)is still largely unsolved,let alone further explorations from a salivary biochemistry *** acquiring the individual taste threshold and evaluating the just noticeable difference(JND).this stody firstly established a quantitative method to assess the magnitude of taste interaction in a binary taste mixture by evaluating the concentration difference upon psychologically-comparable *** change of salty taste intensity(CSI)was therefore defined as the subtraction of JND using sour-salty taste stimulant from JND using pure salty taste stimulant,with a dimension of concentration in mmol/*** was then used to demonstrate how citric acid affected salty taste perception in a salty-sour binary taste mixture in 16 young and healthy *** of citric acid used in the binary taste mixtore were 0.***.0.09.0.***.0.24 and 0.40 mmolL,*** results showed that salty taste perception was enhanced(average CSI of 0.93 mmolL)when the citric acid concentration was low(at 0.05 and 0.09 mmolL).but with an increasing concentration of citric acid ranging from 0.14 to 0.40 mmol/L,this effect gradually turned from enhancement to suppression of salty taste perception(correspondingly a continoously decreasing CSI all the way down to an average of-2.94 mumol/L).It was also found that cystatin SN concentration in participants'unstimulated saliva samples was significantly negatively correlated with salty taste threshold(with and without the presence of citric acid),and it was one of the most significant factors affecting CSI,s shown in multiple regression *** anhydrase VI concentration in participants'unstimulated saliva sanples was also found to be significantly negatively correlated with salty taste recognition(with and without presence of citric acid).but it did not pose signific

文章基于2019年中国家庭金融调查(CHFS)数据,量化了再分配过程中居民获得的社会福利和第三次分配中的其他转移性净收入对相对贫困的缓解效应,并测度了可支配收入形成后进一步消除相对贫困所需的额外福利强度。以居民人均可支配收入中位数的40%为相对贫困线的分析结果表明,再分配确实降低了居民收入的相对贫困率,全国社会福利减贫效应达到15.81%;再分配改变了相对贫困率最低省份的分布格局,但未改变相对贫困率最高省份的分布格局,也未改变相对贫困程度东、中、西依次递增的区域分布模式。居民实际获得的社会福利强度及其减贫效应呈现东、中、西依次递减的特征,社会福利一定程度的错配影响了其整体减贫效应;第三次分配在减少相对贫困方面的作用有很大提升空间,地区差异不大;中国进一步消除相对贫困所需的平均额外福利强度为2.07%,表现出东、中、西依次递增的特征。

The Qinghai Nanshan fault is a larger fault in the Northeastern Xizang *** previous studies,its movement characteristics are mainly investigated with geological and seismic observations,and the tectonic transformation role of the fault on its east is not yet *** study uses data fusion to obtain denser GPS observations near the Qinghai Nanshan *** on tectonic characteristics,we establish a block model to investigate the fault slip rate,locking degree,and slip *** results show that the Qinghai Nanshan fault slip rate is characterized by sinistral and convergent *** the sinistral and convergent rates display a decreasing trend from west to *** locking degree and slip deficit are higher in the western segment(with an average of about 0.74 and 1.1 mm/a)and lower in the eastern ***,we construct a strain rate field using GPS observations to analyze the regional strain *** results indicate that along the fault,the western segment shows a larger shear strain rate and negative dilation *** earthquake records show that the frequency of earthquakes is lower near the *** joint results suggest that the western segment may have a higher earthquake *** addition,the insignificant fault slip rate in the eastern segment may indicate that it does not participate in the tectonic transformation among the Riyueshan,Lajishan,and West Qinling faults.

As the hardware industry moves toward using specialized heterogeneous many-core processors to avoid the effects of the power wall,software developers are finding it hard to deal with the complexity of these *** this paper,we share our experience of developing a programming model and its supporting compiler and libraries for Matrix-3000,which is designed for next-generation exascale supercomputers but has a complex memory hierarchy and processor *** assist its software development,we have developed a software stack from scratch that includes a low-level programming interface and a high-level OpenCL *** low-level programming model offers native programming support for using the bare-metal accelerators of Matrix-3000,while the high-level model allows programmers to use the OpenCL programming *** detail our design choices and highlight the lessons learned from developing system software to enable the programming of bare-metal *** programming models have been deployed in the production environment of an exascale prototype system.
