Conversely, for pulsatile flows, in particular for aortic blood flow, turbulence levels remain low despite relatively large peak velocities. For aortic blood flow, high turbulence levels are intolerable as they would damage the shear-sensitive endothelial cell layer2,3,4,5. Here we show that turbulence in ordinary pipe flow is diminished if the flow is driven in a pulsatile mode that incorporates all the key features of the cardiac waveform. At Reynolds numbers comparable to those of aortic blood flow, turbulence is largely inhibited, whereas at much higher speeds, the turbulent drag is reduced by more than 25%. This specific operation mode is more efficient when compared with steady driving, which is the present situation for virtually all fluid transport processes ranging from heating circuits to water, gas and oil pipelines."}],"article_processing_charge":"No","issue":"7977","volume":621,"publication_status":"published","article_type":"original","oa_version":"None","year":"2023","external_id":{"pmid":["37673988"]},"scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-09-20T12:10:22Z","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"ScienComp"}],"publication_identifier":{"issn":["0028-0836"],"eissn":["1476-4687"]}},{"article_processing_charge":"Yes","article_number":"5633","file":[{"date_created":"2023-09-25T08:32:37Z","success":1,"relation":"main_file","file_id":"14366","content_type":"application/pdf","checksum":"82d2d4ad736cc8493db8ce45cd313f7b","access_level":"open_access","date_updated":"2023-09-25T08:32:37Z","creator":"dernst","file_size":2317272,"file_name":"2023_NatureComm_Riedl.pdf"}],"_id":"14361","abstract":[{"lang":"eng","text":"Whether one considers swarming insects, flocking birds, or bacterial colonies, collective motion arises from the coordination of individuals and entails the adjustment of their respective velocities. In particular, in close confinements, such as those encountered by dense cell populations during development or regeneration, collective migration can only arise coordinately. Yet, how individuals unify their velocities is often not understood. Focusing on a finite number of cells in circular confinements, we identify waves of polymerizing actin that function as a pacemaker governing the speed of individual cells. We show that the onset of collective motion coincides with the synchronization of the wave nucleation frequencies across the population. Employing a simpler and more readily accessible mechanical model system of active spheres, we identify the synchronization of the individuals’ internal oscillators as one of the essential requirements to reach the corresponding collective state. The mechanical ‘toy’ experiment illustrates that the global synchronous state is achieved by nearest neighbor coupling. We suggest by analogy that local coupling and the synchronization of actin waves are essential for the emergent, self-organized motion of cell collectives."}],"date_published":"2023-09-13T00:00:00Z","publication_status":"published","oa":1,"file_date_updated":"2023-09-25T08:32:37Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":14,"article_type":"original","has_accepted_license":"1","oa_version":"Published Version","year":"2023","scopus_import":"1","external_id":{"isi":["001087583700030"],"pmid":["37704595"]},"date_updated":"2023-12-13T12:29:41Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eissn":["2041-1723"]},"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"M-Shop"}],"month":"09","date_created":"2023-09-24T22:01:10Z","publisher":"Springer Nature","isi":1,"publication":"Nature Communications","quality_controlled":"1","department":[{"_id":"MiSi"},{"_id":"NanoFab"},{"_id":"BjHo"}],"intvolume":"        14","status":"public","citation":{"chicago":"Riedl, Michael, Isabelle D Mayer, Jack Merrin, Michael K Sixt, and Björn Hof. “Synchronization in Collectively Moving Inanimate and Living Active Matter.” <i>Nature Communications</i>.

The dynamics of these stripes is central to transition, and recent studies proposed an analogy to directed percolation where the stripes’ proliferation is ultimately responsible for the turbulence becoming sustained. In the present study we focus on the internal stripe dynamics as well as on the eventual stripe expansion, and we compare the underlying mechanisms in pressure- and shear-driven planar flows, respectively, plane-Poiseuille and plane-Couette flow. Despite the similarities of the overall laminar–turbulence patterns, the stripe proliferation processes in the two cases are fundamentally different. Starting from the growth and sustenance of individual stripes, we find that in plane-Couette flow new streaks are created stochastically throughout the stripe whereas in plane-Poiseuille flow streak creation is deterministic and occurs locally at the downstream tip. Because of the up/downstream symmetry, Couette stripes, in contrast to Poiseuille stripes, have two weak and two strong laminar turbulent interfaces. These differences in symmetry as well as in internal growth give rise to two fundamentally different stripe splitting mechanisms. In plane-Poiseuille flow splitting is connected to the elongational growth of the original stripe, and it results from a break-off/shedding of the stripe's tail. In plane-Couette flow splitting follows from a broadening of the original stripe and a division along the stripe into two slimmer stripes."}],"date_published":"2023-11-10T00:00:00Z","article_number":"A21","file":[{"access_level":"open_access","date_updated":"2024-02-15T09:05:21Z","checksum":"17c64c1fb0d5f73252364bf98b0b9e1a","creator":"dernst","file_size":2804641,"file_name":"2023_JourFluidMechanics_Marensi.pdf","success":1,"date_created":"2024-02-15T09:05:21Z","file_id":"14996","relation":"main_file","content_type":"application/pdf"}],"oa":1,"publication_status":"published","volume":974,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2024-02-15T09:05:21Z","has_accepted_license":"1","oa_version":"Published Version","year":"2023","article_type":"original","publication_identifier":{"eissn":["1469-7645"],"issn":["0022-1120"]},"date_updated":"2024-02-15T09:06:23Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"isi":["001088363700001"],"arxiv":["2212.12406"]}},{"publication_status":"published","file_date_updated":"2023-12-06T13:14:15Z","article_processing_charge":"No","file":[{"checksum":"4127c285b34f4bf7fb31ef24f9d14c25","access_level":"closed","date_updated":"2023-12-06T13:13:26Z","file_size":46405919,"creator":"mhenness","file_name":"mike_thesis_v06-12-2023.odt","date_created":"2023-12-06T13:13:26Z","relation":"source_file","file_id":"14648","content_type":"application/vnd.oasis.opendocument.text"},{"embargo":"2024-11-30","file_name":"mike_thesis_v06-12-2023.pdf","creator":"mhenness","file_size":21282155,"date_updated":"2023-12-06T13:14:15Z","access_level":"closed","checksum":"f5203a61eddaf35235bbc51904d73982","content_type":"application/pdf","file_id":"14649","relation":"main_file","date_created":"2023-12-06T13:14:15Z","embargo_to":"open_access"}],"_id":"14641","date_published":"2023-11-30T00:00:00Z","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2023-12-07T14:12:25Z","publication_identifier":{"issn":["2663 - 337X"]},"acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"CampIT"}],"oa_version":"Published Version","has_accepted_license":"1","year":"2023","publisher":"Institute of Science and Technology Austria","degree_awarded":"PhD","department":[{"_id":"GradSch"},{"_id":"BjHo"}],"status":"public","page":"104","month":"11","date_created":"2023-12-04T13:17:37Z","supervisor":[{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754","last_name":"Hof","full_name":"Hof, Björn","first_name":"Björn"}],"project":[{"grant_number":"665385","name":"International IST Doctoral Program","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"language":[{"iso":"eng"}],"keyword":["microfluidics","miceobiology","mutations","quorum sensing"],"ddc":["570"],"doi":"10.15479/at:ista:14641","ec_funded":1,"citation":{"ama":"Hennessey-Wesen M.

Unlike the vast majority of previous numerical studies, we analyse the flow in periodic parallelogram-annular domains, following a coordinate change that aligns one of the parallelogram sides with the spiral pattern. The domain size, shape and spatial resolution have been varied and the results compared with those in a sufficiently large computational orthogonal domain with natural axial and azimuthal periodicity. We find that a minimal parallelogram of the right tilt significantly reduces the computational cost without notably compromising the statistical properties of the supercritical turbulent spiral. Its mean structure, obtained from extremely long time integrations in a co-rotating reference frame using the method of slices, bears remarkable similarity with the turbulent stripes observed in plane Couette flow, the centrifugal instability playing only a secondary role.","lang":"eng"}],"issue":"2246","article_processing_charge":"No","file_date_updated":"2024-01-09T09:13:53Z","volume":381,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"publication_status":"published","oa":1},{"project":[{"_id":"238598C6-32DE-11EA-91FC-C7463DDC885E","name":"Revisiting the Turbulence Problem Using Statistical Mechanics: Experimental Studies on Transitional and Turbulent Flows","grant_number":"662960"}],"acknowledgement":"We thank Baofang Song as well as the developers of Channelflow for sharing their numerical codes, and Mukund Vasudevan and Holger Kantz for fruitful discussions.

A well-known challenge for these techniques is posed by the continuous symmetries, e.g. translations and rotations, of the system under consideration, as drifts in the data dominate the modal expansions without providing an insight into the dynamics of the problem. In the present study, we address this issue for fluid flows in rectangular channels by formulating a continuous symmetry reduction method that eliminates the translations in the streamwise and spanwise directions simultaneously. We demonstrate our method by computing the symmetry-reduced dynamic mode decomposition (SRDMD) of sliding windows of data obtained from the transitional plane-Couette and turbulent plane-Poiseuille flow simulations. In the former setting, SRDMD captures the dynamics in the vicinity of the invariant solutions with translation symmetries, i.e. travelling waves and relative periodic orbits, whereas in the latter, our calculations reveal episodes of turbulent time evolution that can be approximated by a low-dimensional linear expansion."}],"date_published":"2023-01-10T00:00:00Z","arxiv":1,"article_processing_charge":"Yes (via OA deal)"},{"publication_identifier":{"eissn":["2522-5820"]},"date_updated":"2023-08-01T12:50:48Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","external_id":{"isi":["000890148700002"]},"scopus_import":"1","oa_version":"None","year":"2023","article_type":"original","publication_status":"published","volume":5,"article_processing_charge":"No","abstract":[{"lang":"eng","text":"It may come as a surprise that a phenomenon as ubiquitous and prominent as the transition from laminar to turbulent flow has resisted combined efforts by physicists, engineers and mathematicians, and remained unresolved for almost one and a half centuries.

These deviations from ideality impact the process's overall efficiency and the effectiveness of the equipment. To recognize the associated non-ideality, one needs to have enough understanding of the formulation of the equations and in-depth knowledge of the residence time distribution (RTD) data of real reactors. In the current work, step input and pulse input were used to create RTD data for Cascade continuous stirred tank reactors (CSTRs). For the aforementioned configuration, experiments were run at various flow rates to validate the developed characteristic equations. To produce RTD data, distilled water was utilized as the flowing fluid, and NaOH was the tracer substance. The ideal behavior of tracer concentration exits age distribution, and cumulative fraction for each setup and each input was plotted and experimental results were compared with perfect behavior. Deviation of concentration exit age distribution and cumulative fractional distribution from ideal behavior is more in pulse input as compared to a step input. For ideal cases, the exit age distribution curve and cumulative fraction curves are independent of the type of input. But a significant difference was observed for the two cases, which may be due to non-measurable fluctuations in volumetric flow rate, non-achievement of instant injection of tracer in case of pulse input, and slight variations in the sampling period. Further, with increasing flow rate, concentration, exit age, and cumulative fractional curves shifted upward, and this behavior matches with the actual case.","lang":"eng"}],"_id":"12172","date_published":"2023-03-20T00:00:00Z","publication_status":"published","volume":78,"citation":{"short":"B.

Another phenomenon, elasto-inertial turbulence (EIT), has been far less studied even though elastic instabilities have already been observed in dilute polymer solutions before the discovery of polymer drag reduction. EIT is a chaotic state driven by polymer dynamics that is observed across many orders of magnitude in Reynolds number. It involves energy transfer from small elastic scales to large flow scales. The investigation of the mechanisms of EIT offers the possibility to better understand other complex phenomena such as elastic turbulence and maximum drag reduction. In this review, we survey recent research efforts that are advancing the understanding of the dynamics of EIT. We highlight the fundamental differences between EIT and Newtonian/inertial turbulence from the perspective of experiments, numerical simulations, instabilities, and coherent structures. Finally, we discuss the possible links between EIT and elastic turbulence and polymer drag reduction, as well as the remaining challenges in unraveling the self-sustaining mechanism of EIT."}],"file":[{"content_type":"application/pdf","file_id":"12690","relation":"main_file","success":1,"date_created":"2023-02-27T09:23:02Z","file_name":"2023_AnnReviewFluidMech_Dubief.pdf","creator":"dernst","file_size":4036706,"date_updated":"2023-02-27T09:23:02Z","access_level":"open_access","checksum":"2666aa3af2a25252d35eb8681d3edff7"}],"article_processing_charge":"No","issue":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":55,"file_date_updated":"2023-02-27T09:23:02Z","oa":1,"publication_status":"published"},{"author":[{"last_name":"Avila","full_name":"Avila, Marc","first_name":"Marc"},{"full_name":"Barkley, Dwight","first_name":"Dwight","last_name":"Barkley"},{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754","last_name":"Hof","first_name":"Björn","full_name":"Hof, Björn"}],"type":"journal_article","day":"19","title":"Transition to turbulence in pipe flow","citation":{"mla":"Avila, Marc, et al. “Transition to Turbulence in Pipe Flow.” <i>Annual Review of Fluid Mechanics</i>, vol. 55, Annual Reviews, 2023, pp. 575–602, doi:<a href=\"https://doi.org/10.1146/annurev-fluid-120720-025957\">10.1146/annurev-fluid-120720-025957</a>.","chicago":"Avila, Marc, Dwight Barkley, and Björn Hof. “Transition to Turbulence in Pipe Flow.” <i>Annual Review of Fluid Mechanics</i>.

To the observer it is therefore intriguing\r\nwhen a moving collective exhibits order. Collective motion of flocks of birds, schools\r\nof fish or swarms of self-propelled particles or robots have been studied extensively\r\nover the past decades but the mechanisms involved in the transition from chaos to\r\norder remain unclear. Here, the interactions, that in most systems give rise to chaos,\r\nsustain order. In this thesis we investigate mechanisms that preserve, destabilize\r\nor lead to the ordered state. We show that endothelial cells migrating in circular\r\nconfinements transition to a collective rotating state and concomitantly synchronize\r\nthe frequencies of nucleating actin waves within individual cells. Consequently,\r\nthe frequency dependent cell migration speed uniformizes across the population.\r\nComplementary to the WAVE dependent nucleation of traveling actin waves, we\r\nshow that in leukocytes the actin polymerization depending on WASp generates\r\npushing forces locally at stationary patches. Next, in pipe flows, we study methods\r\nto disrupt the self–sustaining cycle of turbulence and therefore relaminarize the\r\nflow. While we find in pulsating flow conditions that turbulence emerges through a\r\nhelical instability during the decelerating phase. Finally, we show quantitatively in\r\nbrain slices of mice that wild-type control neurons can compensate the migratory\r\ndeficits of a genetically modified neuronal sub–population in the developing cortex.","lang":"eng"}],"_id":"12726","date_published":"2023-03-23T00:00:00Z","file":[{"file_name":"Thesis_Riedl_2023.pdf","file_size":63734746,"creator":"cchlebak","description":"the main file is missing the bibliography.

Here, we show that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness requires neither force sensing via the nucleus nor adhesive interactions with a substrate. Upon global compression of the cell body as well as local indentation of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into dot-like structures, providing activation platforms for Arp2/3 nucleated actin patches. These patches locally push against the external load, which can be obstructing collagen fibers or other cells, and thereby create space to facilitate forward locomotion. We show in vitro and in vivo that this WASp function is rate limiting for ameboid leukocyte migration in dense but not in loose environments and is required for trafficking through diverse tissues such as skin and lymph nodes.","lang":"eng"}],"project":[{"grant_number":"747687","name":"Mechanical Adaptation of Lamellipodial Actin Networks in Migrating Cells","_id":"260AA4E2-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"_id":"25FE9508-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"724373","name":"Cellular navigation along spatial gradients"}],"pmid":1,"related_material":{"record":[{"status":"public","id":"12726","relation":"dissertation_contains"},{"relation":"dissertation_contains","id":"14530","status":"public"},{"status":"public","id":"12401","relation":"dissertation_contains"}]},"acknowledgement":"We thank N.

Cortical layers emerge during development and defects in the developmental programs that orchestrate cortical lamination are associated with neurodevelopmental diseases. The developmental principle of cortical layer formation depends on concerted radial projection neuron migration, from their birthplace to their final target position. Radial migration occurs in defined sequential steps, regulated by a large array of signaling pathways. However, based on genetic loss-of-function experiments, most studies have thus far focused on the role of cell-autonomous gene function. Yet, cortical neuron migration in situ is a complex process and migrating neurons traverse along diverse cellular compartments and environments. The role of tissue-wide properties and genetic state in radial neuron migration is however not clear. Here we utilized mosaic analysis with double markers (MADM) technology to either sparsely or globally delete gene function, followed by quantitative single-cell phenotyping. The MADM-based gene ablation paradigms in combination with computational modeling demonstrated that global tissue-wide effects predominate cell-autonomous gene function albeit in a gene-specific manner. Our results thus suggest that the genetic landscape in a tissue critically affects the overall migration phenotype of individual cortical projection neurons. In a broader context, our findings imply that global tissue-wide effects represent an essential component of the underlying etiology associated with focal malformations of cortical development in particular, and neurological diseases in general.","lang":"eng"}],"publication_status":"published","oa":1,"file_date_updated":"2023-08-16T08:00:30Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":1,"article_type":"original","oa_version":"Published Version","has_accepted_license":"1","year":"2022","date_updated":"2023-11-30T10:55:12Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"PreCl"},{"_id":"Bio"}],"publication_identifier":{"eissn":["2753-149X"]}},{"editor":[{"last_name":"Sherwin","first_name":"Spencer","full_name":"Sherwin, Spencer"},{"full_name":"Schmid, Peter","first_name":"Peter","last_name":"Schmid"},{"first_name":"Xuesong","full_name":"Wu, Xuesong","last_name":"Wu"}],"oa_version":"None","year":"2022","publication_identifier":{"eisbn":["9783030679026"],"eissn":["1875-3493"],"isbn":["9783030679019"],"issn":["1875-3507"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-03T12:54:59Z","external_id":{"isi":["000709087600051"]},"scopus_import":"1","article_processing_charge":"No","_id":"10820","abstract":[{"lang":"eng","text":"Streaky structures in the boundary layers are often generated by surface roughness elements and/or free-stream turbulence, and are known to have significant effects on boundary-layer instability. In this paper, we investigate the impact of two forms of streaks on the instability of supersonic boundary layers. The first concerns the streaks generated by an array of spanwise periodic and streamwise elongated surface roughness elements, and our interest is how these streaks influence the lower-branch viscous first modes, whose characteristic wavelength and frequency are on the classical triple-deck scales. By adapting the triple-deck theory in the incompressible regime to the supersonic one, we first derived a simplified system which allows for efficient calculation of the streaks. The asymptotic analysis simplifies a bi-global eigenvalue problem to a one-dimensional problem in the spanwise direction, showing that the instability is controlled at leading order solely by the spanwise-dependent wall shear. In the fundamental configuration, the streaks stabilize first modes at low frequencies but destabilize the high-frequency ones. In the subharmonic configuration, the streaks generally destabilize the first mode across the entire frequency band. Importantly, the spanwise even modes are of radiating nature, i.e. they emit acoustic waves spontaneously to the far field. Streaks of the second form are generated by low-frequency vortical disturbances representing free-stream turbulence. They alter the flow in the entire layer and their effects on instability are investigated by solving the inviscid bi-global eigenvalue problem. Different from the incompressible case, a multitude of compressible instability modes exists, of which the dominant mode is an inviscid instability associated with the spanwise shear. In addition, there exists a separate branch of instability modes that have smaller growth rates but are spontaneously radiating."}],"date_published":"2022-01-01T00:00:00Z","edition":"1","publication_status":"published","volume":38,"conference":{"end_date":"2019-09-06","start_date":"2019-09-02","name":"IUTAM Symposium","location":"London, United Kingdom"},"title":"Effects of streaky structures on the instability of supersonic boundary layers","citation":{"short":"J.

Such an acceleration in epidemic spread is usually attributed to time-dependent effects, e.g. human travel, seasonal behavioral changes, mutations of the pathogen etc. In this case however the acceleration occurred when counter measures such as testing and contact tracing exceeded their capacity limit. Considering Austria as an example, here we show that this dynamics can be captured by a time-independent, i.e. autonomous, compartmental model that incorporates these capacity limits. In this model, the epidemic acceleration coincides with the exhaustion of mitigation efforts, resulting in an increasing fraction of undetected cases that drive the effective reproduction rate progressively higher. We demonstrate that standard models which does not include this effect necessarily result in a systematic underestimation of the effective reproduction rate.","lang":"eng"}],"issue":"7","article_processing_charge":"No","language":[{"iso":"eng"}],"doi":"10.1371/journal.pone.0269975","ddc":["510"],"related_material":{"record":[{"status":"public","relation":"research_data","id":"11711"}]},"day":"18","type":"journal_article","author":[{"full_name":"Budanur, Nazmi B","first_name":"Nazmi B","last_name":"Budanur","id":"3EA1010E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0423-5010"},{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754","full_name":"Hof, Björn","first_name":"Björn","last_name":"Hof"}],"citation":{"mla":"Budanur, Nazmi B., and Björn Hof. “An Autonomous Compartmental Model for Accelerating Epidemics.” <i>PLoS ONE</i>, vol. 17, no. 7, e0269975, Public Library of Science, 2022, doi:<a href=\"https://doi.org/10.1371/journal.pone.0269975\">10.1371/journal.pone.0269975</a>.","ieee":"N.

Multiple model studies reported DP exponents, however, experimental evidence is limited since the largest possible observation times are orders of magnitude shorter than the flows’ characteristic timescales. An exception is cylindrical Couette flow where the limit is not temporal, but rather the realizable system size. We present experiments in a Couette setup of unprecedented azimuthal and axial aspect ratios. Approaching the critical point to within less than 0.1% we determine five critical exponents, all of which are in excellent agreement with the 2+1D DP universality class. The complex dynamics encountered at \r\nthe onset of turbulence can hence be fully rationalized within the framework of statistical mechanics."}],"arxiv":1,"issue":"1","article_processing_charge":"No","language":[{"iso":"eng"}],"doi":"10.1103/PhysRevLett.128.014502","acknowledgement":"We thank T.Menner, T.Asenov, P.

However, interventions to control outbreaks may fundamentally alter epidemic dynamics. Here we reveal how such interventions modify the type of phase transition. In particular, we uncover three distinct types of explosive phase transitions for epidemic dynamics with capacity-limited interventions. Depending on the capacity limit, interventions may (i) leave the standard second order phase transition unchanged but exponentially suppress the probability of large outbreaks, (ii) induce a first-order discontinuous transition to macroscopic outbreaks, or (iii) cause a secondary explosive yet continuous third-order transition. These insights highlight inherent limitations in predicting and containing epidemic outbreaks. More generally our study offers a cornerstone example of a third-order explosive phase transition in complex systems."}],"article_number":"04LT02","file":[{"checksum":"35c5c5cb0eb17ea1b5184755daab9fc9","access_level":"open_access","date_updated":"2023-01-24T07:24:37Z","file_size":1006106,"creator":"dernst","file_name":"2022_JourPhysics_Boerner.pdf","date_created":"2023-01-24T07:24:37Z","success":1,"relation":"main_file","file_id":"12350","content_type":"application/pdf"}],"article_processing_charge":"No","issue":"4","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":3,"file_date_updated":"2023-01-24T07:24:37Z","oa":1,"publication_status":"published","author":[{"full_name":"Börner, Georg","first_name":"Georg","last_name":"Börner"},{"full_name":"Schröder, Malte","first_name":"Malte","last_name":"Schröder"},{"id":"40315C30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5227-4271","last_name":"Scarselli","full_name":"Scarselli, Davide","first_name":"Davide"},{"orcid":"0000-0003-0423-5010","id":"3EA1010E-F248-11E8-B48F-1D18A9856A87","last_name":"Budanur","first_name":"Nazmi B","full_name":"Budanur, Nazmi B"},{"last_name":"Hof","full_name":"Hof, Björn","first_name":"Björn","id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754"},{"first_name":"Marc","full_name":"Timme, Marc","last_name":"Timme"}],"type":"journal_article","day":"25","title":"Explosive transitions in epidemic dynamics","citation":{"mla":"Börner, Georg, et al. “Explosive Transitions in Epidemic Dynamics.” <i>Journal of Physics: Complexity</i>, vol. 3, no. 4, 04LT02, IOP Publishing, 2022, doi:<a href=\"https://doi.org/10.1088/2632-072x/ac99cd\">10.1088/2632-072x/ac99cd</a>.","chicago":"Börner, Georg, Malte Schröder, Davide Scarselli, Nazmi B Budanur, Björn Hof, and Marc Timme. “Explosive Transitions in Epidemic Dynamics.” <i>Journal of Physics: Complexity</i>.

The primary focus of the study is placed on the emergence of drifting–rotating waves (DRW) that capture, in a relatively small domain, the main features of coherent structures typically observed in developed turbulence. The transitional dynamics of the subcritical region, far below the first instability of the laminar circular Couette flow, is determined by the upper and lower branches of DRW solutions originated at saddle-node bifurcations. The mechanism whereby these solutions self-sustain, and the chaotic dynamics they induce, are conspicuously reminiscent of other subcritical shear flows. Remarkably, the flow properties of DRW persist even as the Reynolds number is increased beyond the linear stability threshold of the base flow. Simulations in a narrow parallelogram domain stretched in the azimuthal direction to revolve around the apparatus a full turn confirm that self-sustained vortices eventually concentrate into a localised pattern. The resulting statistical steady state satisfactorily reproduces qualitatively, and to a certain degree also quantitatively, the topology and properties of spiral turbulence as calculated in a large periodic domain of sufficient aspect ratio that is representative of the real system."}],"article_number":"A21","publication_identifier":{"issn":["0022-1120"],"eissn":["1469-7645"]},"date_updated":"2023-08-04T08:54:16Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","external_id":{"isi":["000879446900001"],"arxiv":["2207.12990"]},"scopus_import":"1","year":"2022","oa_version":"Preprint","article_type":"original","isi":1,"publisher":"Cambridge University Press","status":"public","intvolume":"       951","department":[{"_id":"BjHo"}],"quality_controlled":"1","publication":"Journal of Fluid Mechanics","date_created":"2023-01-12T12:04:17Z","month":"11","acknowledgement":"K.D.’s research was supported by an Australian Research Council Discovery Early Career\r\nResearcher Award (DE170100171).
