2025年01月09日，当前，随着税收大数据的建设与发展，数据应用领域不断拓展。而在税收大数据发展和应用的推进过程中，依然有许多方面需进一步完善和拓展。首先，涉税数据的采集和共享机制缺乏明确的法律规定，相关部门制度标准不统一，导致部门之间存在壁垒。其次，数据挖掘不够，缺乏对宏观经济、公司财务数据和第叁方数据的有效利用，加之各地区数据应用标准不统一，影响数据分析的准确性。再次，应用场景单一，目前仍主要局限于税收征管领域，缺乏对税制改革、税费优惠政策等的剖析，切实需要进行多样化、多领域的探索。

帕尔默传球沃特金斯得球转身摆脱德弗里随即起脚劲射得手英格兰2-1绝杀
人有的时候因为工作、情感、生活等不如意，经常会让自己陷入烦闷、压抑、抑郁情绪之中，细细品读这20句话，肯定会让你心情不再沉重，也许会豁然开朗。半场泰山队0射门0角球，进攻毫无威胁，整个球队都毫无生气。赛前想到这场比赛会很艰难，但谁能想到会如此不堪？克雷桑的红牌恐怕不是他自己心态的问题，而是近期整个球队内部一系列难以明说的问题的累积。

Theory predicts that sufficiently strong magnetic fields can halt the accretion flow, producing a magnetically arrested disk (MAD). We analyzed archival multiwavelength observations of an outburst from the black hole x-ray binary MAXI J1820+070 in 2018. The radio and optical fluxes were delayed compared with the x-ray flux by about 8 and 17 days, respectively. We interpret this as evidence for the formation of a MAD. In this scenario, the magnetic field is amplified by an expanding corona, forming a MAD around the time of the radio peak. We propose that the optical delay is due to thermal viscous instability in the outer disk.huaxueChemistryA machine-learning tool to predict substrate-adaptive conditions for Pd-catalyzed C–N couplingsyucezuocuihuatandanouliandediwuzishiyingtiaojiandejiqixuexigongju▲ zuozhe：N.

A tool that gives substrate-adaptive conditions for palladium (Pd)–catalyzed carbon-nitrogen (C–N) couplings is presented. The design and construction of this tool required the generation of an experimental dataset that explores a diverse network of reactant pairings across a set of reaction conditions. A large scope of C–N couplings was actively learned by neural network models by using a systematic process to design experiments. The models showed good performance in experimental validation: Ten products were isolated in more than 85% yield from a range of couplings with out-of-sample reactants designed to challenge the models. Importantly, the developed workflow continually improves the prediction capability of the tool as the corpus of data grows.Ring-opening polymerization of cyclic oligosiloxanes without producing cyclic oligomersbuchanshenghuandijuwudehuandijuguiyangwankaihuanjuhe▲ zuozhe：LIMIAO SHI, AUR?LIE BOUL?GUE-MONDI?RE, DELPHINE BLANC, ANTOINE BACEIREDO, VICEN?

However, there is a small fraction of these chains that inevitably bite back on themselves late in the reaction to produce cyclic impurities. Shi et al. report that benzyl alcohol can complex with the chain end through hydrogen bonding and inhibit the back-biting process. Moreover, they describe a phosphonium counterion that is also stabilized by the alcohol but decomposes in its absence to deactivate chain growth, likewise preventing the by-product formation.qihouhegurenleixueClimate and PaleoanthropologyFluctuating Atlantic inflows modulate Arctic atlantificationbodongdaxiyangliurudiaojiebeiji“daxiyanghua”▲ zuozhe：IGOR V.

Polyakov et al. show that the large-scale weather pattern called the Arctic Dipole causes atmospheric wind patterns that modulate North Atlantic inflows across the Fram Strait and within the Barents Sea, resulting in variations in Arctic Ocean circulation, freshwater fluxes into the Amerasian Basin, ocean stratification, and heat fluxes.Genomic inference of a severe human bottleneck during the Early to Middle Pleistocene transitionzaogengxinshidaozhonggengxinshiguodushiqiyanzhongrenleipingjingdejiyinzutuiduan▲ zuozhe：WANGJIE HU, ZIQIAN HAO, PENGYUAN DU, FABIO DI VINCENZO, GIORGIO MANZI, JIALONG CUI, YUN-XIN FU, YI-HSUAN PAN , AND HAIPENG LI▲ lianjie：https://www.science.org/doi/full/10.1126/science.abq7487▲ zhaiyao：jintian，diqiushangyou80duoyiren，zhuzaizhuodiqiu。danzai80wandao90wannianqian，qingkuangdabuxiangtong。yanjiuzheshiyongyizhongxinkaifadeningjumoxing，cong3000duogexiandairenleijiyinzuzhongyuceguoqurenleiderenkouguimo。gaimoxingfaxian，renleizuxiandeguimozengcongdayue10wanrenjianshaodaodayue1000ren，zhezhongqingkuangchixuliaodayue10wannian。zhezhongxiajiangsihuyuzhuyaodeqihoubianhuahesuihoudewuzhongxingchengshijiantongshifasheng。▲ Abstract：Today, there are more than 8 billion human beings on the planet. We dominate Earth’s landscapes, and our activities are driving large numbers of other species to extinction. Had a researcher looked at the world sometime between 800,000 and 900,000 years ago, however, the picture would have been quite different. Hu et al. used a newly developed coalescent model to predict past human population sizes from more than 3000 present-day human genomes. The model detected a reduction in the population size of our ancestors from about 100,000 to about 1000 individuals, which persisted for about 100,000 years. The decline appears to have coincided with both major climate change and subsequent speciation events.jiliangxueMetrologyEstablishing a new standard of care for calculus using trials with randomized student allocationliyongsuijifenpeixueshengshiyanjianliweijifenxuexixinbiaozhun▲ zuozhe：LAIRD KRAMER, EDGAR FULLER, CHARITY WATSON, ADAM CASTILLO, PABLO DURAN OLIVA▲ lianjie：https://www.science.org/doi/full/10.1126/science.ade9803▲ zhaiyao：zaimeiguogaoxiao，weijifenshihuodeSTEMxueweiderumenkecheng。zaisuoyouzuichugongduSTEMxueweidexueshengzhong，chaoguoyibanderenbiyeshimeiyouhuodexuewei，tongchangshizainuliwanchengkechengzhihou。jiaoshimorencaiyongchuantongdeyijiangzuoweijichudejiaoxuefangshi，jiajuliaobuhegelvdechayi；zheduinvxing、xibanyayiheheirenxueshengdeyingxiangyouweiyanzhong，baoduoliaolaodonglizhonglaizibutongquntiderencaihejianjie。zuozhejinxingliaoyixiangdaxingshiyan，jiangxueshengsuijifenpeidaoweijifenjiaoshi，jiaoshijijidiyuxueshenghezuo（zhiliao），huozheyilaichuantongdeshoukefangshi，jiangtamenshiweibeidongdexuexizhe（duizhao）。zaibutongderenkoutongjiquntizhong，zhezhongzhiliaogengyouxiao，yinweicanyupeiyangliaoduiweijifendegengshenlijie，tigaoliaochengji，bingcujinliaodaibiaoxingbuzudexueshengderongru。zhebiaomingweijifenjiaoxuedexinbiaozhunhewanchengSTEMxueweidejihuizengjia。▲ Abstract：Across US universities, calculus is a gateway course for STEM degrees. Of all students who initially pursue STEM degrees, more than half graduate without one, often after struggling through coursework. Instructors defaulting to traditional lecture-based instruction exacerbates disparities in failure rates; this disproportionately affects women, Hispanic, and Black students, depriving the workforce of talent and insights from diverse groups. Kramer et al. conducted a large trial that randomized students into calculus classrooms where instructors actively engaged students collaboratively (treatment) or relied on traditional lecture styles that treated them as passive learners (control). Across demographic groups, the treatment was more effective, as engagement fostered a deeper understanding of calculus, improved grades, and promoted the inclusion of underrepresented students.“gangweixinziduoshao？zhuanyeyoushimeyaoqiu？yougangqianpeixunma？”jin（5）ri，jiulongpoquerlangjiedao，yichang“bairiqianwanzhuanxiangxingdong”zhuanchangzhaopinhuixiyinbushaoqiuzhizheruchang，gezhaopinqiyezhantaiqianrentouzandong，qiyezhaopinrenyuanreqingdiweiqiuzhizhejiedawenti，jieshaorenzhitiaojian、gongzidaiyu、qiyefulibaozhangdengjibenqingkuang。
