• Estimating the extent and sources of model uncertainty in political science AI翻译

  摘要：Assessing model uncertainty is crucial to quantitative political science. Yet, most available sensitivity analyses focus only on a few modeling choices, most notably the covariate space, while neglecting to jointly consider several equally important modeling choices simultaneously. In this article, we combine the exhaustive and systematic method of the Extreme Bounds Analysis with the more multidimensional logic underpinning the multiverse approach to develop an approach to sensitivity analyse...
• Sp140L functions as a herpesvirus restriction factor suppressing viral transcription and activating interferon- stimulated genes AI翻译

  摘要：Herpesviruses, including Epstein-Barr virus (EBV)-a human oncogenic virus and essential trigger of multiple sclerosis-must bypass host DNA-sensing mechanisms to establish lifelong, latent infection. Therefore, herpesviruses encode viral proteins to disrupt key host factors involved in DNA sensing and viral restriction. The first viral latency protein expressed, EBNA-LP, is essential for transformation of na & iuml;ve B cells and establishment of viral gene expression, yet its role in evading h...

  摘要：Microscopic robots exhibit efficient locomotion in liquids by leveraging fluid dynamics and chemical reactions to generate force asymmetry, thereby enabling critical applications in photonics and biomedicine. However, achieving controllable locomotion of such robots on terrestrial surfaces remains challenging because fluctuating adhesion on nonideal surfaces disrupts the necessary asymmetry for propulsion. Here, we present a microscopic robot composed of three-dimensional nanomembranes, which ...

  摘要：The freezing of droplets on surfaces is closely relevant with various industrial processes such as aviation, navigation, and transportation. Previous studies mainly focus on physiochemically heterogeneous but electrically homogeneous surfaces, on which the presence of vapor pressure gradient between droplets is the predominant mechanism for interdroplet freezing bridging, propagation, and eventual frosting across the entire surface. An interesting yet unanswered question is whether electrostat...
• Reactivation of an embryonic cardiac neural crest transcriptional profile during zebrafish heart regeneration AI翻译

  摘要：During vertebrate development, the heart primarily arises from mesoderm, with crucial contributions from cardiac neural crest (CdNC) cells that migrate to the heart and form a variety of cardiovascular derivatives. Here, by integrating bulk and single cell RNA- seq with ATAC- seq, we identify a gene regulatory subcircuit specific to migratory cardiac crest cells composed of key transcription factors egr1, sox9a, tfap2a, and ets1. Notably, we show that cells expressing the canonical neural cres...

  摘要：A charge density wave (CDW) is a phase of matter characterized by a periodic modulation of valence electron density coupled with lattice distortion. Its formation is closely tied to the dynamical charge susceptibility, x(q, 0)), which reflects the collective electron dynamics of the material. Despite decades of study, x(q, 0)) near a CDW transition has never been measured at nonzero momentum, q, with meV energy resolution. Here, we investigate the canonical CDW transition in ErTe3 using moment...

• An endosymbiotic origin of the crimson pigment from the lac insect AI翻译

  摘要：Symbioses with microorganisms expand the genetic and metabolic repertoire of many insects. The lac insect Kerria lacca (Hemiptera: Sternorrhyncha) is a phloem-feeding scale insect that is brightly colored due to the presence of natural polyhydroxy-anthraquinone pigments called laccaic acids. The deep red pigments possibly provide defense against pathogens and predators and are commercially important as dyes in textiles, lacquerware, and cosmetics. Laccaic acids are categorized as polyketides c...

  摘要：Determining how people behave in contexts governed by social norms can clarify both how norms influence human behavior and how norms evolve. We examined cooperative farming harvest division among the Derung, a Tibeto-Burman-speaking horticultural society in southwestern China. In the village of Dizhengdang, the norm dictates that cofarming harvests should be divided equally among participating households. This contrasts with an alternative norm followed in some other Derung villages that holds...
