Three s-triazine derivatives have been synthesized and their structures been de-termined. These are Compound I: 2,4-dimethyl-6-(p-N,N-dimethylaminostyryl)-s-triazine (abbre-viated to NMe-1., Compound II: 2,4-dimethyl-6-(p-N,N-diethylaminostyryl)-s-triazine (to NEt-1., and Compound III: 2-methyl-4,6-bis(p-N,N-dimethylaminostyryl)-s-triazine (NMe-2). NMe-1.and NEt-1.molecules belong to the D-π-A type with a one-dimensional charge-transfer character. NMe-1.crystallizes to centrosymmetric P1.space group, while NEt-1.to non-centrosymmetric polar Cc space group with all of the molecular charge-transfer axes taking the same orientation. Under the irradiation of 1.64 nm fundamental laser, NEt-1.powder crystals radiate a 2-order harmonic light with an intensity 46.8 times that of urea. The Λ typed NMe-2 molecule, which has a two-dimensional charge-transfer character, crystallizes to polar P21.space group. Its powder crystals exhibit a 2-order harmonic intensity 46.2 times that of urea. The quantum chemical cal-culations and tensor analyses have been carried out to reveal the dependence of the macro 2-order nonlinear optical (NLO) efficiency on the micro 2-order NLO coefficients (β) and on the crystalline packing styles.

The proton-proton(pp)fusion chain dominates the neutrino production in the *** uncertainty of the predicted pp neutrino flux is at the sub-percent level,whereas that of the best measurement is O(1.%).In this study,for the first time,we measure solar pp neutrinos in the electron recoil energy range from 24 to 1.4 keV using the PandaX-4T commissioning data with 0.63 tonne×year *** pp neutrino flux is determined as(8.0±3.9(stat)±1..0(syst))×1.1. s^(-1.cm^(-2),which is consistent with the Standard Solar Model and existing measurements,corresponding to an upper flux limit of 23.3×1.^(1.)s^(-1.cm^(-2)at 90%C.L..

Using e^(+)e^(−)annihilation data corresponding to an integrated luminosity of 2.93 fb^(−1.taken at the center-of-mass energy√s=3.773 GeV with the BESIII detector,a joint amplitude analysis is performed on the decays D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η).The fit fractions of individual components are obtained,and large interferences among the dominant components of the decays D^(0)→a_(1.(1.60)π,D^(0)→π(1.00)π,D^(0)→ρ(770)ρ(770),and D^(0)→2(ππ)_(S)are observed in both *** the obtained amplitude model,the CP-even fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are determined to be(75.2±1.1.(stat).±1.5_(syst.))%and(68.9±1.5_(stat).±2.4_(syst.))%,*** branching fractions of D^(0)→π^(+)π^(−)π^(+)π^(−)and D^(0)→π^(+)π^(−)π^(0)π^(0)(non-η)are measured to be(0.688±0.01._(stat.)±0.01._(syst.))%and(0.951.0.025_(stat.)±0.021.(syst.))%,*** amplitude analysis provides an important model for the binning strategy in measuring the strong phase parameters of D^(0)→4πwhen used to determine the CKM angleγ(ϕ_(3))via the B^(−)→DK^(−)decay.

奥陶系在塔里木盆地西北缘柯坪地区广泛出露。本研究对该地区任英沟剖面上奥陶统凯迪阶上部的阿日苏组和铁热克阿瓦提组进行了系统的主、微量元素地球化学分析,通过一系列地球化学指标(CIA、CIAcorr.、Sr/Ba、U/Th、Ni/Co、V/Cr、Al_(2)O_(3)/TiO_(2)、TiO_(2)/Zr等)和主、微量元素判别图解,得出以下几点认识:(1.阿日苏组和铁热克阿瓦提组记录了化学风化作用先减弱后增强的变化趋势,对应了区域内古温度先降低后升高的过程,这与全球范围内Boda事件中期的降温-升温事件吻合;(2)该套地层沉积水体盐度不高,海水呈间歇性漫入,这与上覆的志留系柯坪塔格组底部地层的开阔海沉积环境不同;(3)该套地层的物源以远源较古老的沉积岩地层为主,混入近源早奥陶世地层,其沉积物的搬运和沉积过程受到南天山洋洋壳消减的影响;(4)柯坪塔格山北麓印干组顶部的厚层生物灰岩代表了柯坪地区早古生代最后的碳酸盐岩沉积,之后转换为以阿日苏组、铁热克阿瓦提组、柯坪塔格组、塔塔埃尔塔格组和克兹尔塔格组为代表的巨厚碎屑岩沉积,对应于整个塔里木盆地在奥陶纪晚期发生的沉积相转化事件。这一沉积模式的转换,可能与晚奥陶世至志留纪发生的区域内南天山洋洋壳消减有密切关系。

随着中国总人口的不断增加以及改革开放以来经济的飞速发展,中国面临来自气候变化的健康威胁也在不断上升.与此同时,中国也处于一个独特的机遇窗口期,如果能够有效应对气候变化带来的健康风险,将造福今后几代人的健康.反之,如果没有及时、充分的应对措施,气候变化对中国居民健康和生命的威胁将与日俱增.为了推动更及时且有利于改善人群健康的气候应对行动,由清华大学牵头建立的柳叶刀倒计时亚洲中心在全球柳叶刀倒计时工作的基础上[1.2],从2020年开始,聚焦气候变化对中国人群健康的影响进行全面且系统的评估[3,4].
