Experimental observation of non-Abelian topological charges and edge states非阿贝尓拓扑结构荷可带系统软件的试验观察▲ 【微信号码:yaodaoyaofang】:Qinghua Guo, Tianshu Jiang, Ruo-Yang Zhang, Lei Zhang, Zhao-Qing Zhang, et al.▲ 连接:https://www.nature.com/articles/s41586-021-03521-3▲ 引言近期,科学研究工作人员明确提出了非阿贝尔拓扑结构荷的定义,这类正电荷具备多种多样的非互换的辫构造,而且好几个带隙缠结在一起。本科学研究试验观查了时间与空间逆变技术对称性维护同轴电缆互联网中的非阿贝尔拓扑结构荷。四元数拓扑结构荷清楚地投射到一个本征座标架曲面上。除此之外,大家还发觉了非阿贝尓体—边相匹配,给予了界限/畴壁态遍布的全局性主视图。大家的工作中打开了了解非阿贝尔拓扑结构荷表现的大门口,这也许会造成有意思的观查,如二维系统软件中运动轨迹依靠的Dirac/Weyl连接点撞击、三维中可以的连接点线构形,并很有可能给予对歪曲多层石墨烯材料一些强有关相的看法。▲ AbstractVery recently, researchers proposed the notion of non-Abelian topological charges, which possess non-commutative and fruitful braiding structures with multiple (more than one) bandgaps tangled together. Here we experimentally observe the non-Abelian topological charges in a time-reversal and inversion-symmetric transmission line network. The quaternion-valued non-Abelian topological charges are clearly mapped onto an eigenstate-frame sphere. Moreover, we find a non-Abelian quotient relation that provides a global perspective on the distribution of edge/domain-wall states. Our work opens the door towards characterization and manipulation of non-Abelian topological charges, which may lead to interesting observables such as trajectory-dependent Dirac/Weyl node collisions in two-dimensional systems, admissible nodal line configurations in three dimensions, and may provide insight into certain strongly correlated phases of twisted bilayer graphene.
Quantum-enhanced nonlinear microscopy量子科技提高离散系统光学显微镜▲ 【微信号码:yaodaoyaofang】:Catxere A. Casacio, Lars S.

Our microscope is a coherent Raman microscope that offers subwavelength resolution and incorporates bright quantum correlated illumination. The correlations allow imaging of molecular bonds within a cell with a 35 per cent improved signal-to-noise ratio compared with conventional microscopy, corresponding to a 14 per cent improvement in concentration sensitivity. This enables the observation of biological structures that would not otherwise be resolved. Coherent Raman microscopes allow highly selective biomolecular fingerprinting in unlabelled specimens, but photodamage is a major roadblock for many applications. By showing that the photodamage limit can be overcome, our work will enable order-of-magnitude improvements in the signal-to-noise ratio and the imaging speed.

In under six hours, our method automatically generates chip floorplans that are superior or comparable to those produced by humans in all key metrics, including power consumption, performance and chip area. To achieve this, we pose chip floorplanning as a reinforcement learning problem, and develop an edge-based graph convolutional neural network architecture capable of learning rich and transferable representations of the chip. As a result, our method utilizes past experience to become better and faster at solving new instances of the problem, allowing chip design to be performed by artificial agents with more experience than any human designer. Our method was used to design the next generation of Google’s artificial intelligence (AI) accelerators, and has the potential to save thousands of hours of human effort for each new generation.
Swarm Learning for decentralized and confidential clinical machine learning用以区块链技术且信息保密临床医学深度学习的Swarm Learning技术性▲ 【微信号码:yaodaoyaofang】:Stefanie Warnat-Herresthal, Hartmut Schultze, Krishnaprasad Lingadahalli Shastry, et al.▲ 连接:https://www.nature.com/articles/s41586-021-03583-3▲ 引言在这里,为了更好地在没有违背隐私法的情形下融合来源于全世界一切数据信息使用者的一切医疗数据,大家引进了Swarm Learning——一种区块链技术的AI技术性,融合了边缘计算、根据数字货币的对等网络和融洽,与此同时信息保密,不用中间融洽器。为了更好地表明应用Swarm Learning开发设计分布式系统数据信息疾病分类别器的可行性分析,大家选用了4个异质性病症(新冠肺炎、肺结核、败血症和肺病)的病案。根据来源于127项临床实验的16400好几份血夜转录组及其超出95000张拍胸片片,大家发觉Swarm Learning分类器的性能指标好于在单独定点医疗机构开发设计的分类器。除此之外,Swarm Learning在设计方案上彻底达到了信息保密要求。大家坚信,这类办法将明显加速精准诊疗的引进。▲ AbstractHere, to facilitate the integration of any medical data from any data owner worldwide without violating privacy laws, we introduce Swarm Learning—a decentralized machine-learning approach that unites edge computing, blockchain-based peer-to-peer networking and coordination while maintaining confidentiality without the need for a central coordinator, thereby going beyond federated learning. To illustrate the feasibility of using Swarm Learning to develop disease classifiers using distributed data, we chose four use cases of heterogeneous diseases (COVID-19, tuberculosis, leukaemia and lung pathologies). With more than 16,400 blood transcriptomes derived from 127 clinical studies with non-uniform distributions of cases and controls and substantial study biases, as well as more than 95,000 chest X-ray images, we show that Swarm Learning classifiers outperform those developed at individual sites. In addition, Swarm Learning completely fulfils local confidentiality regulations by design. We believe that this approach will notably accelerate the introduction of precision medicine.

Reconstruction of ancient microbial genomes from the human gut从人们肠胃中复建古时候微生物菌种基因▲ 【微信号码:yaodaoyaofang】:Marsha C. Wibowo, Zhen Yang, Maxime Borry, Alexander Hübner, Kun D. Huang, Braden T. Tierney, et al.▲ 连接:https://www.nature.com/articles/s41586-021-03532-0▲ 引言在这里,大家对古排泄物中的微生物菌种基因实现了规模性从头开始拼装。从英国南部和西班牙八个储存完好无损的人们古排泄物样版(1000 - 2000年)中,大家复建了49八个中等水平和高品质的微生物菌种基因。在18一个最历史悠久与人们肠胃发源有关的基因中,有39%具备之前末知的种群基因。这为核心的人们共生体甲烷气体短链球菌明确提出了多元化时刻表。与来源于八个我国的789个当代人们肠道微生物组样版对比,古排泄物样版和非现代化人们肠道微生物组更类似。古排泄物样版的功能设计表明,抗菌素承受病理性和粘蛋白溶解遗传基因的进化速率显著较低,比现代化后的肠道微生物组有关的流通性基因遗传元器件更聚集。▲ AbstractHere we performed a large-scale de novo assembly of microbial genomes from palaeofaeces. From eight authenticated human palaeofaeces samples (1,000–2,000 years old) with well-preserved DNA from southwestern USA and Mexico, we reconstructed 498 medium- and high-quality microbial genomes. Among the 181 genomes with the strongest evidence of being ancient and of human gut origin, 39% represent previously undescribed species-level genome bins. Tip dating suggests an approximate diversification timeline for the key human symbiont Methanobrevibacter smithii. In comparison to 789 present-day human gut microbiome samples from eight countries, the palaeofaeces samples are more similar to non-industrialized than industrialized human gut microbiomes. Functional profiling of the palaeofaeces samples reveals a markedly lower abundance of antibiotic-resistance and mucin-degrading genes, as well as enrichment of mobile genetic elements relative to industrial gut microbiomes.

Anisotropic satellite galaxy quenching modulated by black hole activity各种各样通讯卫星星球猝灭受超级黑洞主题活动危害▲ 【微信号码:yaodaoyaofang】:Ignacio Martín-Navarro, Annalisa Pillepich, Dylan Nelson, Vicente Rodriguez-Gomez, et al.▲ 连接:https://www.nature.com/articles/s41586-021-03545-9▲ 引言在这里,大家汇报对124163个通讯卫星星球的档案资料数据的分析,这种通讯卫星星球坐落于2963一个暗能量晕的势阱中,品质在太阳质量的1012到1014中间。大家发觉猝灭的通讯卫星星球相对性较少发生现如今核心星球的小轴上。由于超级黑洞主题活动预估会首先向寄主星球的小轴方位喷涌品质和动能,这一观查很有可能看起来违背判断力。殊不知,大家的观察说明各种各样数据信号刚好来自于极大光环中的超级黑洞意见反馈的抛射特性,即由主题活动星球核推动的流出物消除了星球周边的物质,降低了碰撞工作压力,进而储存了通讯卫星星球中的行星产生。这一表述获得了IllustrisTNG天文学模拟计算组的适用,虽然该实体模型的亚网格图完成的超级黑洞意见反馈是各向异性的。▲ AbstractHere we report an analysis of archival data on 124,163 satellite galaxies in the potential wells of 29,631 dark matter halos with masses between 1012 and 1014 solar masses. We find that quenched satellite galaxies are relatively less frequent along the minor axis of their central galaxies. This observation might appear counterintuitive given that black hole activity is expected to eject mass and energy preferentially in the direction of the minor axis of the host galaxy. We show, however, that the observed anisotropic signal results precisely from the ejective nature of black hole feedback in massive halos, as outflows powered by active galactic nuclei clear out the circumgalactic medium, reducing the ram pressure and thus preserving star formation in satellite galaxies. This interpretation is supported by the IllustrisTNG suite of cosmological numerical simulations, even though the model’s sub-grid implementation of black hole feedback is effectively isotropic.药道网【帕唑帕尼网上订购方式】。印度的全世界海淘药店:印度的帕唑帕尼价钱。
