2024年12月29日,而故事最后来自镇上女人们的善意,也并非是皆大欢喜的圆满,反倒是对人性的另一次剖析,从前的诽谤、殴打、撕衣服是凌辱,如今的“善意”其实是在心底对玛莲娜的再次凌辱。

These are the two largest fresh impact craters discovered by the Mars Reconnaissance Orbiter since operations started 16 years ago. The impacts created two of the largest seismic events (magnitudes greater than 4) recorded by InSight during its 3-year mission. The combination of orbital imagery and seismic ground motion enables the investigation of subsurface and atmospheric energy partitioning of the impact process on a planet with a thin atmosphere and the first direct test of martian deep-interior seismic models with known event distances. The impact at 35°N excavated blocks of water ice, which is the lowest latitude at which ice has been directly observed on Mars.Surface waves and crustal structure on Marshuoxingbiaomianbohedikejiegou▲ zuozhe:D.

By measuring group velocity dispersion along the impact-lander path, we obtained a direct constraint on crustal structure away from the InSight lander. The crust north of the equatorial dichotomy had a shear wave velocity of approximately 3.2 kilometers per second in the 5- to 30-kilometer depth range, with little depth variation. This implies a higher crustal density than inferred beneath the lander, suggesting either compositional differences or reduced porosity in the volcanic areas traversed by the surface waves. The lower velocities and the crustal layering observed beneath the landing site down to a 10-kilometer depth are not a global feature. Structural variations revealed by surface waves hold implications for models of the formation and thickness of the martian crust.cailiaokexueMaterials SciencePlastic deformation in silicon nitride ceramics via bond switching at coherent interfacesdanhuaguitaocizaigonggejiemianshangtongguojianqiehuanchanshengsuxingbianxing▲ zuozhe:JIE ZHANG, GUANGHUA LIU, WEI CUI, YIYAO GE, SONGMO DU, YIXUAN GAO, ET AL.▲ lianjie:https://www.science.org/doi/10.1126/science.abq7490▲ zhaiyao:gongjiajianhetaocijuyouyouyidexingneng(baokuoyingdu、qiangdu、huaxueduoxing、nairexinghenaifushixing),danyouyuqishiwencuixing,ruheshixiangengguangfandeyingyongpojutiaozhan。yujinshuzhongdeyuanzikeyiyanzhuohuayimianhuadongyibianxingbutong,gongjiajianhetaociyouyuyuanzijiangongjiajiandeqiangdingxiangxing,qibianxingxuyaoduanjian。zhezuizhonghuidaozhijiazaishifashengduanlie。yanjiuzutichuliaoyizhongkebianxinggongjiajianhedanhuagui(Si3N4)taocideshejifangfa,qitedianshijuyougonggejiemiandeshuangxiangjiegou。zaigonggejiemianshangshixianliaolianxujianqiehuan,zheyouliyuyingliyoudaoxiangbian,bingzuizhongchanshengsuxingbianxingnengli。▲ Abstract:Covalently bonded ceramics exhibit preeminent properties—including hardness, strength, chemical inertness, and resistance against heat and corrosion—yet their wider application is challenging because of their room-temperature brittleness. In contrast to the atoms in metals that can slide along slip planes to accommodate strains, the atoms in covalently bonded ceramics require bond breaking because of the strong and directional characteristics of covalent bonds. This eventually leads to catastrophic failure on loading. We present an approach for designing deformable covalently bonded silicon nitride (Si3N4) ceramics that feature a dual-phase structure with coherent interfaces. Successive bond switching is realized at the coherent interfaces, which facilitates a stress-induced phase transformation and, eventually, generates plastic deformability.huaxueChemistryStereochemical editing logic powered by the epimerization of unactivated tertiary stereocentersweijihuosanjilitizhongxindechaxiangyigouzhulilitihuaxuebianjiluoji▲ zuozhe:YU-AN ZHANG, VIGNESH PALANI, ALEXANDER E.

In this work, we describe a complementary paradigm for the synthesis of chiral molecules and their isomers, which tunes the three-dimensional structure of a molecule at a late stage. Key to the success of this strategy is the development of a mild and highly general photocatalytic method composed of decatungstate polyanion and disulfide cocatalysts, which enable the interconversion of unactivated tertiary stereogenic centers that were previously configurationally fixed. We showcase the versatility of this method—and the implementation of stereoediting logic—by the rapid construction of chiral scaffolds that would be challenging to access using existing tools and by the late-stage stereoediting of complex targets.Closed-loop optimization of general reaction conditions for heteroaryl Suzuki-Miyaura couplingzafangjiSuzuki-Miyauraoulianfanyingtongyongtiaojiandebihuanyouhua▲ zuozhe:NICHOLAS H.

Discovering more general reaction conditions requires considering vast regions of chemical space derived from a large matrix of substrates crossed with a high-dimensional matrix of reaction conditions, rendering exhaustive experimentation impractical. Here, we report a simple closed-loop workflow that leverages data-guided matrix down-selection, uncertainty-minimizing machine learning, and robotic experimentation to discover general reaction conditions. Application to the challenging and consequential problem of heteroaryl Suzuki-Miyaura cross-coupling identified conditions that double the average yield relative to a widely used benchmark that was previously developed using traditional approaches. This study provides a practical road map for solving multidimensional chemical optimization problems with large search spaces.gonggongweishengPublic HealthEvolution and antiviral activity of a human protein of retroviral originnizhuanlubingdulaiyuanrenleidanbaizhidejinhuahekangbingduhuoxing▲ zuozhe:JOHN A.

In several mammals, the envelope proteins encoded by these elements protect against exogenous viruses, but this activity has not been documented with endogenously expressed envelopes in humans. We report that the human genome harbors a large pool of envelope-derived sequences with the potential to restrict retroviral infection. To test this, we characterized an envelope-derived protein, Suppressyn. We found that Suppressyn is expressed in human preimplantation embryos and developing placenta using its ancestral retroviral promoter. Cell culture assays showed that Suppressyn, and its hominoid orthologs, could restrict infection by extant mammalian type D retroviruses. Our data support a generalizable model of retroviral envelope co-option for host immunity and genome defense.maixiangyiban,weidaoxianmei
