自然语言处理建构在“道元(token)”之上,道元是AI算法处理和学习各种文字、图像与声音数据类型的基本元素。道元生成的过程与老子“道生一,一生二,二生三,三生万物”相似。大语言模型利用“间距”产生道元后,转换成位,透过大量数据的学习与计算,进行新的道元生成与意义重组。由于结合概率重组,人工智能出现类似于人类行为的不可预测性和独特性。未来借鉴老子哲学和汉字的多样性,人工智能可以发展出更全面和创新的框架。

将Fe-MIL-101通过聚偏二氟乙烯固定在三聚氰胺泡沫(MF)上制备MIL-101@MF复合材料,将其用做枪头固相萃取(PT-SPE)的吸附剂,并结合液相色谱-串联质谱法实现了鸡蛋中酰胺醇类(CAPs)抗生素的高效测定。对MIL-101@MF的形貌、晶体结构和官能团进行了表征,证实了Fe-MIL-101的成功合成并固定在MF上。优化了PT-SPE萃取条件,在多反应监测模式下,以基质标准曲线结合内标法同时测定氯霉素(CAP)、甲砜霉素(TAP)、氟苯尼考(FF)。由于氢键、π-π、静电等相互作用,MIL-101@MF对3种CAPs具有极高的萃取能力,萃取过程小于3 min,材料可重复使用60次。3种CAPs的定量下限为0.1μg/kg,加标回收率为78.2%~108%。采用该方法测定80批次鸡蛋样品,TAP的检出率2.50%,含量为0.21~1.2μg/kg;FF的检出率8.75%,含量为0.47~4.2μg/kg。该方法操作简便、灵敏度高且定量准确,有望应用于动物源性食品中多兽药残留的预处理中,为我国进出口食品安全残留监控提供技术支撑。

MHC class II expression is controlled mainly at transcriptional level by class II transactivator(CIITA),which is a non-DNA binding coactivator and serves as a master control factor for MHC class II genes ***,we describe the function of a novel splice-isoform of CIITA,DC-expressed caspase inhibitory isoform of CIITA(or DC-CASPIC),and we show that the expression of DCCASPIC in DC is upregulated upon lipopolysaccharides(LPS)***-CASPIC localizes to mitochondria,and protein-protein interaction study demonstrates that DC-CASPIC interacts with caspases and inhibits its activity in ***,DC-CASPIC suppresses caspases-induced degradation of nitric oxide synthase-2(NOS2)and subsequently promotes the synthesis of nitric oxide(NO).NO is an essential regulatory molecule that modulates the capability of DC in stimulating T cell proliferation/activation in vitro;hence,overexpression of DC-CASPIC in DC enhances this ***,our findings reveal that DC-CASPIC is a key molecule that regulates caspases activity and NO synthesis in DC.

This study presents a seismic fragility analysis and ultimate spectral displacement assessment of regular low-rise masonry infilled （MI） reinforced concrete （RC） buildings using a coefficient-based method. The coefficient-based method does not require a complicated finite element analysis; instead, it is a simplifed procedure for assessing the spectral acceleration and displacement of buildings subjected to earthquakes. A regression analysis was first performed to obtain the best-fitting equations for the inter-story drift ratio （IDR） and period shift factor of low-rise MI RC buildings in response to the peak ground acceleration of earthquakes using published results obtained from shaking table tests. Both spectral acceleration- and spectral displacement-based fragility curves under various damage states （in terms of IDR） were then constructed using the coefficient-based method. Finally, the spectral displacements of low-rise MI RC buildings at the ultimate （or near- collapse） state obtained from this paper and the literature were compared. The simulation results indicate that the fragility curves obtained from this study and other previous work correspond well. Furthermore, most of the spectral displacements of low-rise MI RC buildings at the ultimate state from the literature fall within the bounded spectral displacements predicted by the coefficient-based method.

与传统水热合成工艺相比,采用微波水热合成新工艺可以快速合成比表面积大、孔体积和孔径大、孔径分布范围更窄、孔洞呈六方排布的有序介孔材料MCM-41.微波水热合成工艺合成的MCM-41具有合成效率高、成功率高等特点,为此类介孔材料商业化提供了高效的技术手段.采用传统水热工艺合成MCM-41通常需要48～72h,而采用微波水热合成技术仅需要30min.采用X射线粉晶衍射(XRD),氮气吸附等技术手段对合成MCM-41材料的物相、比表面积、孔体积、孔径等进行了表征.采用微波水热合成MCM-41的工艺参数为:微波处理的温度120℃,时间30min,微波辐射功率500W,经过滤、洗涤、干燥、焙烧等处理后,得到的MCM-41具有六方排布的孔系,晶格常数a0=4.4nm,比表面积可达1113m2/g,平均孔径为2.7nm,与选用同样配方采用传统水热合成工艺合成的MCM-41的性能相当,却极大提高了合成效率.采用微波水热合成工艺,同样可以合成立方晶系的MCM-48和六方晶系的SBA-15等介孔氧化硅分子筛材料.此外,在微波合成的MCM-41中采用液相工艺成功组装了ZnO纳米粒子,并对组装在MCM-41中的纳米ZnO粒子进行了光催化降解苯酚的实验研究.

We propose a quasi-degenerate dark matter scenario to simultaneously explain the 1.4 TeV peak in the high-energy cosmic-ray electron-positron spectrum reported by the DAMPE collaboration very recently and the 3.5 keV X-ray line observed in galaxies clusters and from the Galactic centre and confirmed by the Chandra and NuSTAR satellites. We consider a dark S U（2）′× U（1）′ gauge symmetry under which the dark matter is a Dirac fermion doublet composed of two S U（2）′ doublets with non-trivial U（1 ）′ charges. At the one-loop level the two dark fermion components can have a mass split as a result of the dark gauge symmetry breaking. Through the exchange of a mediator scalar doublet the two quasi-degenerate dark fermdons can mostly annihilate into the electron-positron pairs at the tree level for explaining the 1.4 TeV positron anomaly, meanwhile, the heavy dark fermion can very slowly decay into the light dark fermion with a photon at the one-loop level for explaining the 3.5 keV X-ray line. Our dark fermions can be also verified in the direct detection experiments.
