{"doi":"10.1103/physrevfluids.6.103102","title":"Helical trajectories of swimming cells with a flexible flagellar hook","abstract":"A model bacterium with a flexible flagellar hook generically swims along a helical trajectory, even when incorporating detailed hydrodynamics. A bifurcation in the hook's equilibrium bending angle below a critical bending stiffness can have a dramatic effect on the trajectory's helical pitch angle. Analytical predictions for the bifurcation's dependence on the hook's spontaneous curvature, the shape of the cell body, and the flagellum geometry are provided.","journal":"Physical Review Fluids","year":2021,"id":224607,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9512,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":826632,"name":"Wilson Lough","orcid":"0009-0000-7207-068X","position":1,"is_corresponding":false},{"id":516523,"name":"Saverio E.
