CME relies on the precise recruitment of regulators for vesicle maturation and release. Homologues of components of mammalian vesicle scission are strong candidates to be part of the scissin machinery in plants, but the precise roles of these proteins in this process is not fully understood. Here, we characterised the roles of Plant Dynamin-Related Proteins 2 (DRP2s) and SH3-domain containing protein 2 (SH3P2), the plant homologue to Dynamins’ recruiters, like Endophilin and Amphiphysin, in the CME by combining high-resolution imaging of endocytic events in vivo and characterisation of the purified proteins in vitro. Although DRP2s and SH3P2 arrive similarly late during CME and physically interact, genetic analysis of the Dsh3p1,2,3 triple-mutant and complementation assays with non-SH3P2-interacting DRP2 variants suggests that SH3P2 does not directly recruit DRP2s to the site of endocytosis. These observations imply that despite the presence of many well-conserved endocytic components, plants have acquired a distinct mechanism for CME. One Sentence Summary In contrast to predictions based on mammalian systems, plant Dynamin-related proteins 2 are recruited to the site of Clathrin-mediated endocytosis independently of BAR-SH3 proteins."}],"project":[{"name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","call_identifier":"H2020"}],"publication_status":"draft","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"LifeSc"},{"_id":"Bio"}],"date_created":"2023-11-22T10:17:49Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","month":"10"},{"language":[{"iso":"eng"}],"date_updated":"2026-07-06T12:50:45Z","department":[{"_id":"GradSch"},{"_id":"JoDa"}],"oa":1,"ec_funded":1,"ddc":["610"],"author":[{"id":"443DB6DE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3862-1235","full_name":"Michalska, Julia M","first_name":"Julia M","last_name":"Michalska"}],"fulldoi":"https://doi.org/10.15479/at:ista:12470","citation":{"ieee":"J.

Our\r\nprimary focus lies on two particular types of VQAs: the Quantum Approximate Optimization\r\nAlgorithm (QAOA), used for solving binary optimization problems, and the Variational Quantum\r\nEigensolver (VQE), utilized for finding ground states of quantum many-body systems.\r\nIn the first part of the thesis, we examine the issue of effective parameter initialization for\r\nthe QAOA. The work demonstrates that random initialization of the QAOA often leads to\r\nconvergence in local minima with sub-optimal performance. To mitigate this issue, we propose\r\nan initialization of QAOA parameters based on the Trotterized Quantum Annealing (TQA).\r\nWe show that TQA initialization leads to the same performance as the best of an exponentially\r\nscaling number of random initializations.\r\nThe second study introduces Transition States (TS), stationary points with a single direction\r\nof descent, as a tool for systematically exploring the QAOA optimization landscape. This\r\nleads us to propose a novel greedy parameter initialization strategy that guarantees for the\r\nenergy to decrease with increasing number of circuit layers.\r\nIn the third section, we extend the QAOA to qudit systems, which are higher-dimensional\r\ngeneralizations of qubits. This chapter provides theoretical insights and practical strategies for\r\nleveraging the increased computational power of qudits in the context of quantum optimization\r\nalgorithms and suggests a quantum circuit for implementing the algorithm on an ion trap\r\nquantum computer.\r\nFinally, we propose an algorithm to avoid “barren plateaus”, regions in parameter space with\r\nvanishing gradients that obstruct efficient parameter optimization. This novel approach relies\r\non defining a notion of weak barren plateaus based on the entropies of local reduced density\r\nmatrices and showcases how these can be efficiently quantified using shadow tomography.\r\nTo illustrate the approach we employ the strategy in the VQE and show that it allows to\r\nsuccessfully avoid barren plateaus in the initialization and throughout the optimization.\r\nTaken together, this thesis greatly enhances our understanding of parameter initialization and\r\noptimization in VQAs, expands the scope of QAOA to higher-dimensional quantum systems,\r\nand presents a method to address the challenge of barren plateaus using the VQE. These\r\ninsights are instrumental in advancing the field of near-term quantum computation."}],"supervisor":[{"last_name":"Serbyn","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","first_name":"Maksym","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"oa_version":"Published Version","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publication_status":"published","project":[{"_id":"bd660c93-d553-11ed-ba76-fb0fb6f49c0d","name":"IBM PhD Nomination Fellowship - Stefan Sack"},{"name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","grant_number":"850899","call_identifier":"H2020"}],"doi_confirm":"1","month":"11","publication_identifier":{"issn":["2663-337X"]},"has_accepted_license":"1","article_processing_charge":"No"},{"author":[{"id":"dd622248-f6e0-11ea-865d-ce382a1c81a5","orcid":"0000-0001-5400-8508","first_name":"Stefan","full_name":"Sack, Stefan","last_name":"Sack"},{"last_name":"Medina Ramos","id":"CE680B90-D85A-11E9-B684-C920E6697425","orcid":"0000-0002-5383-2869","full_name":"Medina Ramos, Raimel A","first_name":"Raimel A"},{"last_name":"Kueng","first_name":"Richard","full_name":"Kueng, Richard"},{"last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2399-5827","full_name":"Serbyn, Maksym","first_name":"Maksym"}],"ddc":["530"],"ec_funded":1,"arxiv":1,"oa":1,"language":[{"iso":"eng"}],"date_updated":"2026-11-08T23:31:03Z","department":[{"_id":"MaSe"}],"tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_created":"2023-06-07T06:57:32Z","publisher":"American Physical Society","external_id":{"arxiv":["2209.01159"],"isi":["001016927100012"]},"corr_author":"1","fulldoi":"https://doi.org/10.1103/physreva.107.062404","citation":{"short":"S.

For a random initialization, the optimization typically leads to local minima with poor performance, motivating the search for initialization strategies of QAOA variational parameters. Although numerous heuristic initializations exist, an analytical understanding and performance guarantees for large p remain evasive.We introduce a greedy initialization of QAOA which guarantees improving performance with an increasing number of layers. Our main result is an analytic construction of 2p + 1 transition states—saddle points with a unique negative curvature direction—for QAOA with p + 1 layers that use the local minimum of QAOA with p layers. Transition states connect to new local minima, which are guaranteed to lower the energy compared to the minimum found for p layers. We use the GREEDY procedure to navigate the exponentially increasing with p number of local minima resulting from the recursive application of our analytic construction. The performance of the GREEDY procedure matches available initialization strategies while providing a guarantee for the minimal energy to decrease with an increasing number of layers p.

Interestingly, the X has undergone turnover in multiple fly species (Diptera) after being conserved for more than 450 MY. The long evolutionary distance between Diptera and other sequenced insect clades makes it difficult to infer what could have contributed to this sudden increase in rate of turnover. Here, we produce the first genome and transcriptome of a long overlooked sister-order to Diptera: Mecoptera. We compare the scorpionfly Panorpa cognata X-chromosome gene content, expression, and structure, to that of several dipteran species as well as more distantly-related insect orders (Orthoptera and Blattodea). We find high conservation of gene content between the mecopteran X and the dipteran Muller F element, as well as several shared biological features, such as the presence of dosage compensation and a low amount of genetic diversity, consistent with a low recombination rate. However, the two homologous X chromosomes differ strikingly in their size and number of genes they carry. Our results therefore support a common ancestry of the mecopteran and ancestral dipteran X chromosomes, and suggest that Muller element F shrank in size and gene content after the split of Diptera and Mecoptera, which may have contributed to its turnover in dipteran insects."}],"publication":"Molecular Biology and Evolution","volume":40,"file_date_updated":"2024-01-02T11:39:38Z","issue":"12","doi":"10.1093/molbev/msad245","day":"01","publication_identifier":{"eissn":["1537-1719"],"issn":["0737-4038"]},"has_accepted_license":"1","article_processing_charge":"Yes","quality_controlled":"1","month":"12","project":[{"grant_number":"F8810","name":"The highjacking of meiosis for asexual reproduction","_id":"34ae1506-11ca-11ed-8bc3-c14f4c474396"},{"name":"Mechanisms and Evolution of Reproductive Plasticity","_id":"ebb230e0-77a9-11ec-83b8-87a37e0241d3","grant_number":"ESP39 49461"}],"publication_status":"published","pmid":1,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","acknowledgement":"We thank the Vicoso lab for their assistance with specimen collection, and Tim Connallon for valuable comments and suggestions on earlier versions of the manuscript.

Here we report a study of the transport and microwave response of Josephson arrays with interactions exceeding this level. Contrary to expectations, we observe that the array resistance drops dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and then saturates at low temperature. Applying a magnetic field, we eventually observe a transition to a highly resistive regime. These observations can be understood within a theoretical picture that accounts for the effect of thermal fluctuations on the insulating phase. On the basis of the agreement between experiment and theory, we suggest that apparent superconductivity in our Josephson arrays arises from melting the zero-temperature insulator."}],"publication":"Nature Physics","volume":19,"file_date_updated":"2024-01-29T11:25:38Z","day":"01","doi":"10.1038/s41567-023-02161-w","scopus_import":"1","title":"Superconductivity from a melted insulator in Josephson junction arrays","keyword":["General Physics and Astronomy"],"date_published":"2023-11-01T00:00:00Z","acknowledgement":"We thank D.

The evolution of X chromosomes after they stop recombining in males, but before they become hemizygous, has not been well explored theoretically. We use the diffusion approximation to infer substitution rates of beneficial and deleterious mutations under such a scenario. Our results show that selection is less efficient on diploid X loci than on autosomal and hemizygous X loci under a wide range of parameters. This “slower-X” effect is stronger for genes affecting primarily (or only) male fitness, and for sexually antagonistic genes.

However, their fundamental limits, the performance of gradient methods and the features learnt during optimization remain poorly understood, even in the two-layer setting. In fact, earlier work has considered either linear autoencoders or specific training regimes (leading to vanishing or diverging compression rates). Our paper addresses this gap by focusing on non-linear two-layer autoencoders trained in the challenging proportional regime in which the input dimension scales linearly with the size of the representation. Our results characterize the minimizers of the population risk, and show that such minimizers are achieved by gradient methods; their structure is also unveiled, thus leading to a concise description of the features obtained via training. For the special case of a sign activation function, our analysis establishes the fundamental limits for the lossy compression of Gaussian sources via (shallow) autoencoders. Finally, while the results are proved for Gaussian data, numerical simulations on standard datasets display the universality of the theoretical predictions.","lang":"eng"}],"arxiv":1,"oa":1,"author":[{"first_name":"Aleksandr","full_name":"Shevchenko, Aleksandr","id":"F2B06EC2-C99E-11E9-89F0-752EE6697425","last_name":"Shevchenko"},{"last_name":"Kögler","first_name":"Kevin","full_name":"Kögler, Kevin","id":"94ec913c-dc85-11ea-9058-e5051ab2428b"},{"first_name":"Hamed","full_name":"Hassani, Hamed","last_name":"Hassani"},{"last_name":"Mondelli","orcid":"0000-0002-3242-7020","full_name":"Mondelli, Marco","first_name":"Marco","id":"27EB676C-8706-11E9-9510-7717E6697425"}],"date_updated":"2026-11-08T23:31:11Z","language":[{"iso":"eng"}],"department":[{"_id":"MaMo"},{"_id":"DaAl"}],"publisher":"ML Research Press","date_created":"2023-10-29T23:01:17Z","alternative_title":["PMLR"],"intvolume":"       202","citation":{"short":"A.

Tunable directionality can be achieved by applying external magnetic fields that modify optical selection rules, by using nonlinear effects, or interactions with vibrations. However, these approaches are less suitable to control microwave photon propagation inside integrated superconducting quantum devices. Here, we demonstrate on-demand tunable directional scattering based on two periodically modulated transmon qubits coupled to a transmission line at a fixed distance. By changing the relative phase between the modulation tones, we realize unidirectional forward or backward photon scattering. Such an in-situ switchable mirror represents a versatile tool for intra- and inter-chip microwave photonic processors. In the future, a lattice of qubits can be used to realize topological circuits that exhibit strong nonreciprocity or chirality.","lang":"eng"}],"scopus_import":"1","title":"Tunable directional photon scattering from a pair of superconducting qubits","year":"2023","file":[{"content_type":"application/pdf","date_created":"2023-06-06T07:31:20Z","relation":"main_file","success":1,"access_level":"open_access","file_id":"13123","file_name":"2023_NaturePhysics_Redchenko.pdf","date_updated":"2023-06-06T07:31:20Z","checksum":"a857df40f0882859c48a1ff1e2001ec2","file_size":1654389,"creator":"dernst"}],"article_number":"2998","_id":"13117","acknowledgement":"The authors thank W.D.

of natural scenes are not uniform - their structure varies dramatically from ground to sky. It remains unknown whether these non-uniformities are reflected in the large-scale organization of the early visual system and what benefits such adaptations would confer. Here, by relying on the efficient coding hypothesis, we predict that changes in the structure of receptive fields across visual space increase the efficiency of sensory coding. We show experimentally that, in agreement with our predictions, receptive fields of retinal ganglion cells change their shape along the dorsoventral retinal axis, with a marked surround asymmetry at the visual horizon. Our work demonstrates that, according to principles of efficient coding, the panoramic structure of natural scenes is exploited by the retina across space and cell-types.

During bacterial cell division, FtsZ -- a prokaryotic homologue of the eukaryotic protein tubulin -- polymerizes into treadmilling filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments can form dynamic chiral assemblies. However, how the active and passive properties of individual filaments relate to these large-scale self-organized structures remains poorly understood. Here, we connect single filament properties with the mesoscopic scale by combining minimal active matter simulations and biochemical reconstitution experiments. We show that density and flexibility of active chiral filaments define their global order. At intermediate densities, curved, flexible filaments organize into chiral rings and polar bands. An effectively nematic organization dominates for high densities and for straight, mutant filaments with increased rigidity. Our predicted phase diagram captures these features quantitatively, demonstrating how the flexibility, density and chirality of active filaments affect their collective behaviour. Our findings shed light on the fundamental properties of active chiral matter and explain how treadmilling FtsZ filaments organize during bacterial cell division.

During bacterial cell division, FtsZ—a prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments can form dynamic chiral assemblies. However, how the active and passive properties of individual filaments relate to these large-scale self-organized structures remains poorly understood. Here we connect single-filament properties with the mesoscopic scale by combining minimal active matter simulations and biochemical reconstitution experiments. We show that the density and flexibility of active chiral filaments define their global order. At intermediate densities, curved, flexible filaments organize into chiral rings and polar bands. An effectively nematic organization dominates for high densities and for straight, mutant filaments with increased rigidity. Our predicted phase diagram quantitatively captures these features, demonstrating how the flexibility, density and chirality of the active filaments affect their collective behaviour. Our findings shed light on the fundamental properties of active chiral matter and explain how treadmilling FtsZ filaments organize during bacterial cell division.","lang":"eng"}],"file_date_updated":"2024-01-30T14:28:30Z","volume":19,"publication":"Nature Physics","day":"01","doi":"10.1038/s41567-023-02218-w"},{"department":[{"_id":"AnKi"}],"date_updated":"2026-11-08T23:31:23Z","language":[{"iso":"eng"}],"oa":1,"author":[{"first_name":"Thomas","full_name":"Minchington, Thomas","id":"7d1648cb-19e9-11eb-8e7a-f8c037fb3e3f","last_name":"Minchington"},{"last_name":"Rus","orcid":"0000-0001-8703-1093","full_name":"Rus, Stefanie","first_name":"Stefanie","id":"4D9EC9B6-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Kicheva","first_name":"Anna","full_name":"Kicheva, Anna","orcid":"0000-0003-4509-4998","id":"3959A2A0-F248-11E8-B48F-1D18A9856A87"}],"ddc":["570"],"article_type":"original","intvolume":"        35","corr_author":"1","fulldoi":"https://doi.org/10.1016/j.coisb.2023.100459","citation":{"apa":"Minchington, T., Rus, S., &#38; Kicheva, A.

This complex process requires coordination between the generation of cell mass and the morphogenetic mechanisms that sculpt tissues. These processes are regulated by morphogen signalling pathways and mechanical forces. Yet, in many systems, it is unclear how biochemical and mechanical signalling are quantitatively interpreted to determine the behaviours of individual cells and how they contribute to growth and morphogenesis at the tissue scale. In this review, we discuss the development of the vertebrate neural tube and somites as an example of the state of knowledge, as well as the challenges in understanding the mechanisms of tissue size control in vertebrate organogenesis. We highlight how the recent advances in stem cell differentiation and organoid approaches can be harnessed to provide new insights into this question.","lang":"eng"}],"oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","project":[{"name":"Mechanisms of tissue size regulation in spinal cord development","_id":"bd7e737f-d553-11ed-ba76-d69ffb5ee3aa","grant_number":"101044579"},{"grant_number":"F7802","_id":"059DF620-7A3F-11EA-A408-12923DDC885E","name":"Stem Cell Modulation in Neural Development and Regeneration/ P02-Morphogen control of growth and pattern in the spinal cord"},{"grant_number":"SC19-011","name":"The regulatory logic of pattern formation in the vertebrate dorsal neural tube","_id":"9B9B39FA-BA93-11EA-9121-9846C619BF3A"}],"quality_controlled":"1","month":"09","publication_identifier":{"eissn":["2452-3100"]},"article_processing_charge":"Yes (via OA deal)","has_accepted_license":"1"},{"month":"03","quality_controlled":"1","article_processing_charge":"Yes (via OA deal)","has_accepted_license":"1","publication_identifier":{"issn":["0962-1083"],"eissn":["1365-294X"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"grant_number":"P32166","_id":"05959E1C-7A3F-11EA-A408-12923DDC885E","name":"Snapdragon Speciation"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","name":"Formal methods for the design and analysis of complex systems","call_identifier":"FWF","grant_number":"Z211"},{"grant_number":"101055327","name":"Understanding the evolution of continuous genomes","_id":"bd6958e0-d553-11ed-ba76-86eba6a76c00"}],"pmid":1,"publication_status":"published","abstract":[{"text":"The term “haplotype block” is commonly used in the developing field of haplotype-based inference methods. We argue that the term should be defined based on the structure of the Ancestral Recombination Graph (ARG), which contains complete information on the ancestry of a sample. We use simulated examples to demonstrate key features of the relationship between haplotype blocks and ancestral structure, emphasizing the stochasticity of the processes that generate them. Even the simplest cases of neutrality or of a “hard” selective sweep produce a rich structure, often missed by commonly used statistics. We highlight a number of novel methods for inferring haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate how they can be used to define haplotype blocks using an empirical data set. While the advent of new, computationally efficient methods makes it possible to apply these concepts broadly, they (and additional new methods) could benefit from adding features to explore haplotype blocks, as we define them. Understanding and applying the concept of the haplotype block will be essential to fully exploit long and linked-read sequencing technologies.","lang":"eng"}],"oa_version":"Published Version","day":"01","doi":"10.1111/mec.16793","issue":"6","volume":32,"publication":"Molecular Ecology","file_date_updated":"2023-08-16T08:15:41Z","title":"On the origin and structure of haplotype blocks","scopus_import":"1","keyword":["Genetics","Ecology","Evolution","Behavior and Systematics"],"related_material":{"record":[{"id":"20694","status":"public","relation":"dissertation_contains"}]},"type":"journal_article","status":"public","acknowledgement":"We thank the Barton group for useful discussion and feedback during the writing of this article.

Forward genetic approaches in the model plant Arabidopsis thaliana have identified major components of auxin signalling and established the canonical mechanism mediating transcriptional and thus developmental reprogramming. In this textbook view, TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFBs) are auxin receptors, which act as F-box subunits determining the substrate specificity of the Skp1-Cullin1-F box protein (SCF) type E3 ubiquitin ligase complex. Auxin acts as a “molecular glue” increasing the affinity between TIR1/AFBs and the Aux/IAA repressors. Subsequently, Aux/IAAs are ubiquitinated and degraded, thus releasing auxin transcription factors from their repression making them free to mediate transcription of auxin response genes (Yu et al., 2022). Nonetheless, accumulating evidence suggests existence of rapid, non-transcriptional responses downstream of TIR1/AFBs such as auxin-induced cytosolic calcium (Ca2+) transients, plasma membrane depolarization and apoplast alkalinisation, all converging on the process of root growth inhibition and root gravitropism (Li et al., 2022). Particularly, these rapid responses are mostly contributed by predominantly cytosolic AFB1, while the long-term growth responses are mediated by mainly nuclear TIR1 and AFB2-AFB5 (Li et al., 2021; Prigge et al., 2020; Serre et al., 2021). How AFB1 conducts auxin-triggered rapid responses and how it is different from TIR1 and AFB2-AFB5 remains elusive. Here, we compare the roles of TIR1 and AFB1 in transcriptional and rapid responses by modulating their subcellular localization in Arabidopsis and by testing their ability to mediate transcriptional responses when part of the minimal auxin circuit reconstituted in yeast.","lang":"eng"}],"oa_version":"Published Version","das_tickbox":"1","doi":"10.1016/j.molp.2023.06.007","day":"01","publication":"Molecular Plant","volume":16,"file_date_updated":"2024-01-29T10:37:05Z","issue":"7"},{"issue":"1","volume":70,"publication":"Glia","file_date_updated":"2022-03-04T08:55:27Z","doi":"10.1002/glia.24101","day":"01","oa_version":"Published Version","abstract":[{"lang":"eng","text":"Microglia cells are active players in regulating synaptic development and plasticity in the brain.

In this study, we characterized the effects of pharmacological microglia depletion, achieved by administration of PLX5622, on hippocampal CA3-CA1 synapses of adult wild type mice. Following microglial depletion, we observed a reduction of spontaneous and evoked glutamatergic activity associated with a decrease of dendritic spine density. We also observed the appearance of immature synaptic features and higher levels of plasticity. Microglia depleted mice showed a deficit in the acquisition of the Novel Object Recognition task. These events were accompanied by hippocampal astrogliosis, although in the absence ofneuroinflammatory condition. PLX-induced synaptic changes were absent in Cx3cr1−/− mice, highlighting the role of CX3CL1/CX3CR1 axis in microglia control of synaptic functioning. Remarkably, microglia repopulation after PLX5622 withdrawal was associated with the recovery of hippocampal synapses and learning functions.

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."}],"oa_version":"None","doi":"10.1007/978-3-030-67902-6_51","day":"01","publication":"IUTAM Laminar-Turbulent Transition","volume":38},{"file":[{"date_created":"2022-03-07T07:55:23Z","content_type":"application/pdf","success":1,"relation":"main_file","file_size":8478995,"file_id":"10831","file_name":"2022_Cell_Yanagida.pdf","checksum":"ae305060e8031297771b89dae9e36a29","date_updated":"2022-03-07T07:55:23Z","access_level":"open_access","creator":"dernst"}],"year":"2022","_id":"10825","acknowledgement":"We are grateful to H.

An important example is the mammalian inner cell mass, in which the primitive endoderm (PrE, founder of the yolk sac) physically segregates from the epiblast (EPI, founder of the fetus). While the molecular requirements have been well studied, the physical mechanisms determining spatial segregation between EPI and PrE remain elusive. Here, we investigate the mechanical basis of EPI and PrE sorting. We find that rather than the differences in static cell surface mechanical parameters as in classical sorting models, it is the differences in surface fluctuations that robustly ensure physical lineage sorting. These differential surface fluctuations systematically correlate with differential cellular fluidity, which we propose together constitute a non-equilibrium sorting mechanism for EPI and PrE lineages. By combining experiments and modeling, we identify cell surface dynamics as a key factor orchestrating the correct spatial segregation of the founder embryonic lineages."}],"project":[{"call_identifier":"H2020","grant_number":"851288","_id":"05943252-7A3F-11EA-A408-12923DDC885E","name":"Design Principles of Branching Morphogenesis"}],"pmid":1,"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eissn":["1097-4172"],"issn":["0092-8674"]},"has_accepted_license":"1","article_processing_charge":"No","quality_controlled":"1","month":"02","date_updated":"2025-07-10T11:50:00Z","department":[{"_id":"EdHa"}],"language":[{"iso":"eng"}],"oa":1,"ec_funded":1,"ddc":["570"],"author":[{"last_name":"Yanagida","full_name":"Yanagida, Ayaka","first_name":"Ayaka"},{"last_name":"Corujo-Simon","first_name":"Elena","full_name":"Corujo-Simon, Elena"},{"first_name":"Christopher K.","full_name":"Revell, Christopher K.","last_name":"Revell"},{"last_name":"Sahu","id":"55BA52EE-A185-11EA-88FD-18AD3DDC885E","first_name":"Preeti","full_name":"Sahu, Preeti"},{"last_name":"Stirparo","first_name":"Giuliano G.","full_name":"Stirparo, Giuliano G."},{"full_name":"Aspalter, Irene M.","first_name":"Irene M.","last_name":"Aspalter"},{"first_name":"Alex K.","full_name":"Winkel, Alex K.","last_name":"Winkel"},{"first_name":"Ruby","full_name":"Peters, Ruby","last_name":"Peters"},{"last_name":"De Belly","first_name":"Henry","full_name":"De Belly, Henry"},{"full_name":"Cassani, Davide A.D.","first_name":"Davide A.D.","last_name":"Cassani"},{"full_name":"Achouri, Sarra","first_name":"Sarra","last_name":"Achouri"},{"first_name":"Raphael","full_name":"Blumenfeld, Raphael","last_name":"Blumenfeld"},{"full_name":"Franze, Kristian","first_name":"Kristian","last_name":"Franze"},{"full_name":"Hannezo, Edouard B","first_name":"Edouard B","orcid":"0000-0001-6005-1561","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","last_name":"Hannezo"},{"last_name":"Paluch","first_name":"Ewa K.","full_name":"Paluch, Ewa K."},{"last_name":"Nichols","full_name":"Nichols, Jennifer","first_name":"Jennifer"},{"full_name":"Chalut, Kevin J.","first_name":"Kevin J.","last_name":"Chalut"}],"intvolume":"       185","isi":1,"article_type":"original","fulldoi":"https://doi.org/10.1016/j.cell.2022.01.022","citation":{"ista":"Yanagida A, Corujo-Simon E, Revell CK, Sahu P, Stirparo GG, Aspalter IM, Winkel AK, Peters R, De Belly H, Cassani DAD, Achouri S, Blumenfeld R, Franze K, Hannezo EB, Paluch EK, Nichols J, Chalut KJ. 2022.

The mechanisms underpinning this cross-modal plasticity are poorly understood. We probe such mechanisms by performing a forward genetic screen for mutants with enhanced O2 perception in Caenorhabditis elegans. Multiple mutants exhibiting increased O2 responsiveness concomitantly show defects in other sensory responses. One mutant, qui-1, defective in a conserved NACHT/WD40 protein, abolishes pheromone-evoked Ca2+ responses in the ADL pheromone-sensing neurons. At the same time, ADL responsiveness to pre-synaptic input from O2-sensing neurons is heightened in qui-1, and other sensory defective mutants, resulting in enhanced neurosecretion although not increased Ca2+ responses. Expressing qui-1 selectively in ADL rescues both the qui-1 ADL neurosecretory phenotype and enhanced escape from 21% O2. Profiling ADL neurons in qui-1 mutants highlights extensive changes in gene expression, notably of many neuropeptide receptors. We show that elevated ADL expression of the conserved neuropeptide receptor NPR-22 is necessary for enhanced ADL neurosecretion in qui-1 mutants, and is sufficient to confer increased ADL neurosecretion in control animals. Sensory loss can thus confer cross-modal plasticity by changing the peptidergic connectome."}],"volume":11,"publication":"eLife","file_date_updated":"2022-03-07T07:39:25Z","doi":"10.7554/eLife.68040","day":"24","has_accepted_license":"1","article_processing_charge":"No","publication_identifier":{"eissn":["2050-084X"]},"month":"02","quality_controlled":"1","pmid":1,"publication_status":"published","project":[{"grant_number":"209504/A/17/Z","_id":"23870BE8-32DE-11EA-91FC-C7463DDC885E","name":"Molecular mechanisms of neural circuit function"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","acknowledgement":"We would like to thank Gemma Chandratillake and Merav Cohen for identifying mutants and José David Moñino Sánchez for his help on neurosecretion assays.
