Such systems are exposed to both internal, localized, failures and external disturbances or perturbations. Owing to their interconnected structure, complex systems might be severely degraded, to the point of disintegration or systemic dysfunction. Examples include cascading failures, triggered by an initially localized overload in power systems, and the critical slowing downs of ecosystems which can be driven towards extinction. In recent years, this general phenomenon has been investigated by framing localized and systemic failures in terms of perturbations that can alter the function of a system. We capitalize on this mathematical framework to review theoretical and computational approaches to characterize robustness and resilience of complex networks. We discuss recent approaches to mitigate the impact of perturbations in terms of designing robustness, identifying early-warning signals and adapting responses. In terms of applications, we compare the performance of the state-of-the-art dismantling techniques, highlighting their optimal range of applicability for practical problems, and provide a repository with ready-to-use scripts, a much-needed tool set. Complex biological, social and engineering systems operate through intricate connectivity patterns. Understanding their robustness and resilience against disturbances is crucial for applications. This Review addresses systemic breakdown, cascading failures and potential interventions, highlighting the importance of research at the crossroad of statistical physics and machine learning.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 2","pages":"114-131"},"PeriodicalIF":38.5,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139422122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This field started with optics-based proposals in the 1970s. Progress has required breakthroughs in physics, chemistry, materials science, laser science and engineering. This Review focuses on the physics underlying optics-based approaches, including interference lithography, tomographic volumetric additive manufacturing, stereolithography, continuous liquid-interface printing, light-sheet printing, parallelized spatiotemporal focusing and (multi-)focus scanning. Light–matter interactions that are discussed include one-photon, two-photon, multi-photon or cascaded nonlinear optical absorption processes for excitation and stimulated-emission depletion or excited-state absorption followed by reverse intersystem crossing for de-excitation. The future physics challenges lie in further boosting three metrics: spatial resolution, rate of voxel creation and range of available dissimilar material properties. Engineering challenges lie in achieving these metrics in compact, low-cost and low-energy-consumption instruments and in identifying new applications. This Review categorizes the physics of many different light-based 3D printing modalities and expounds on the light–matter interactions required for the creation of (multi-)material 3D structures. An outlook is provided regarding key printing performance parameters and future directions.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 2","pages":"99-113"},"PeriodicalIF":38.5,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138576372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The desire to explore the properties of atoms and their nuclei in a regime of very large numbers of electrons, protons and neutrons has motivated new experimental facilities to create new elements and nuclides at the limits of atomic number and mass. But the small production rates and short lifetimes of superheavy nuclei and their atoms mean that ‘atom-at-a-time’ studies are the only experimental way to probe them. The physical and chemical data obtained so far, augmented by theoretical calculations, indicate significant deviations from extrapolations from lighter elements and isotopes. This situation raises the following question: how much further can one push the limits of the periodic table? In this Review, we describe the major challenges in the field of the superheavy elements and speculate about future directions. Advances in superheavy element studies providing insight into the nuclear and atomic structure and the chemical behaviour of these exotic short-lived systems will help push to the limit of the periodic table of elements and revise the concept of the island of stability.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 2","pages":"86-98"},"PeriodicalIF":38.5,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138576578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acquiring spatiotemporal information of development, especially for humans, is limited by technical and ethical constraints. Thus, both stem cell-based, in vitro development models and theoretical models have been constructed to recapitulate morphogenetic events during development. These in vitro experimental and theoretical models offer accessibility, efficiency and modulability. However, their physiological relevance often remains obscure, owing to their simplistic nature, which obstructs their applicability as faithful and predictive models of natural development. We examine existing in vitro experimental and theoretical models of various developmental events and compare them with the current knowledge of natural development, with particular considerations of biomechanical driving forces and stereotypic morphogenetic features. We highlight state-of-the-art methods used to construct these in vitro models and emphasize the biomechanical and biophysical principles these models have helped unveil. We also discuss challenges faced by the current in vitro experimental and theoretical models and propose how theoretical modelling and in vitro experimental models should be combined with in vivo studies to advance fundamental understanding of development. Beyond in vivo models, stem cell-based in vitro models and theoretical models of morphogenesis have been constructed to recapitulate morphogenetic events during embryo development with heightened quantitative specificity. This Review discusses the accomplishments, challenges and opportunities of these models in promoting knowledge of mammalian development, including human development.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"6 1","pages":"28-44"},"PeriodicalIF":38.5,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138576583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
