对美型妖精大混战的结局怎么看?觉得祭璃雪找到真爱了吗? - 知乎
感觉心情好一点就想穿一种风格，想要穿的酷一点又是一种风格，这完全是个人的事情。该男子的观点显然是对女性的误解和不尊重。在现代社会，我们应该尊重每个人的个人选择和权利。女性的穿着并不代表她们就想要故意吸引男性或者刻意在迎合男性。

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.化(Hua)学(Xue)ChemistryA machine-learning tool to predict substrate-adaptive conditions for Pd-catalyzed C–N couplings预(Yu)测(Ce)钯(Zuo)催(Cui)化(Hua)碳(Tan)氮(Dan)偶(Ou)联(Lian)的(De)底(Di)物(Wu)自(Zi)适(Shi)应(Ying)条(Tiao)件(Jian)的(De)机(Ji)器(Qi)学(Xue)习(Xi)工(Gong)具(Ju)▲ 作(Zuo)者(Zhe)：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 oligomers不(Bu)产(Chan)生(Sheng)环(Huan)低(Di)聚(Ju)物(Wu)的(De)环(Huan)低(Di)聚(Ju)硅(Gui)氧(Yang)烷(Wan)开(Kai)环(Huan)聚(Ju)合(He)▲ 作(Zuo)者(Zhe)：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.气(Qi)候(Hou)和(He)古(Gu)人(Ren)类(Lei)学(Xue)Climate and PaleoanthropologyFluctuating Atlantic inflows modulate Arctic atlantification波(Bo)动(Dong)大(Da)西(Xi)洋(Yang)流(Liu)入(Ru)调(Diao)节(Jie)北(Bei)极(Ji)“大(Da)西(Xi)洋(Yang)化(Hua)”▲ 作(Zuo)者(Zhe)：IGOR V.

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.计(Ji)量(Liang)学(Xue)MetrologyEstablishing a new standard of care for calculus using trials with randomized student allocation利(Li)用(Yong)随(Sui)机(Ji)分(Fen)配(Pei)学(Xue)生(Sheng)试(Shi)验(Yan)建(Jian)立(Li)微(Wei)积(Ji)分(Fen)学(Xue)习(Xi)新(Xin)标(Biao)准(Zhun)▲ 作(Zuo)者(Zhe)：LAIRD KRAMER, EDGAR FULLER, CHARITY WATSON, ADAM CASTILLO, PABLO DURAN OLIVA▲ 链(Lian)接(Jie)：https://www.science.org/doi/full/10.1126/science.ade9803▲ 摘(Zhai)要(Yao)：在(Zai)美(Mei)国(Guo)高(Gao)校(Xiao)，微(Wei)积(Ji)分(Fen)是(Shi)获(Huo)得(De)STEM学(Xue)位(Wei)的(De)入(Ru)门(Men)课(Ke)程(Cheng)。在(Zai)所(Suo)有(You)最(Zui)初(Chu)攻(Gong)读(Du)STEM学(Xue)位(Wei)的(De)学(Xue)生(Sheng)中(Zhong)，超(Chao)过(Guo)一(Yi)半(Ban)的(De)人(Ren)毕(Bi)业(Ye)时(Shi)没(Mei)有(You)获(Huo)得(De)学(Xue)位(Wei)，通(Tong)常(Chang)是(Shi)在(Zai)努(Nu)力(Li)完(Wan)成(Cheng)课(Ke)程(Cheng)之(Zhi)后(Hou)。教(Jiao)师(Shi)默(Mo)认(Ren)采(Cai)用(Yong)传(Chuan)统(Tong)的(De)以(Yi)讲(Jiang)座(Zuo)为(Wei)基(Ji)础(Chu)的(De)教(Jiao)学(Xue)方(Fang)式(Shi)，加(Jia)剧(Ju)了(Liao)不(Bu)合(He)格(Ge)率(Lv)的(De)差(Cha)异(Yi)；这(Zhe)对(Dui)女(Nv)性(Xing)、西(Xi)班(Ban)牙(Ya)裔(Yi)和(He)黑(Hei)人(Ren)学(Xue)生(Sheng)的(De)影(Ying)响(Xiang)尤(You)为(Wei)严(Yan)重(Zhong)，剥(Bao)夺(Duo)了(Liao)劳(Lao)动(Dong)力(Li)中(Zhong)来(Lai)自(Zi)不(Bu)同(Tong)群(Qun)体(Ti)的(De)人(Ren)才(Cai)和(He)见(Jian)解(Jie)。作(Zuo)者(Zhe)进(Jin)行(Xing)了(Liao)一(Yi)项(Xiang)大(Da)型(Xing)试(Shi)验(Yan)，将(Jiang)学(Xue)生(Sheng)随(Sui)机(Ji)分(Fen)配(Pei)到(Dao)微(Wei)积(Ji)分(Fen)教(Jiao)室(Shi)，教(Jiao)师(Shi)积(Ji)极(Ji)地(Di)与(Yu)学(Xue)生(Sheng)合(He)作(Zuo)（治(Zhi)疗(Liao)），或(Huo)者(Zhe)依(Yi)赖(Lai)传(Chuan)统(Tong)的(De)授(Shou)课(Ke)方(Fang)式(Shi)，将(Jiang)他(Ta)们(Men)视(Shi)为(Wei)被(Bei)动(Dong)的(De)学(Xue)习(Xi)者(Zhe)（对(Dui)照(Zhao)）。在(Zai)不(Bu)同(Tong)的(De)人(Ren)口(Kou)统(Tong)计(Ji)群(Qun)体(Ti)中(Zhong)，这(Zhe)种(Zhong)治(Zhi)疗(Liao)更(Geng)有(You)效(Xiao)，因(Yin)为(Wei)参(Can)与(Yu)培(Pei)养(Yang)了(Liao)对(Dui)微(Wei)积(Ji)分(Fen)的(De)更(Geng)深(Shen)理(Li)解(Jie)，提(Ti)高(Gao)了(Liao)成(Cheng)绩(Ji)，并(Bing)促(Cu)进(Jin)了(Liao)代(Dai)表(Biao)性(Xing)不(Bu)足(Zu)的(De)学(Xue)生(Sheng)的(De)融(Rong)入(Ru)。这(Zhe)表(Biao)明(Ming)微(Wei)积(Ji)分(Fen)教(Jiao)学(Xue)的(De)新(Xin)标(Biao)准(Zhun)和(He)完(Wan)成(Cheng)STEM学(Xue)位(Wei)的(De)机(Ji)会(Hui)增(Zeng)加(Jia)。▲ 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.
