Several families of communication-reduction methods, such as quantization, large-batch methods, and gradient sparsification, have been proposed. To date, gradient sparsification methods--where each node sorts gradients by magnitude, and only communicates a subset of the components, accumulating the rest locally--are known to yield some of the largest practical gains. Such methods can reduce the amount of communication per step by up to \\emph{three orders of magnitude}, while preserving model accuracy. Yet, this family of methods currently has no theoretical justification. This is the question we address in this paper. We prove that, under analytic assumptions, sparsifying gradients by magnitude with local error correction provides convergence guarantees, for both convex and non-convex smooth objectives, for data-parallel SGD. The main insight is that sparsification methods implicitly maintain bounds on the maximum impact of stale updates, thanks to selection by magnitude. Our analysis and empirical validation also reveal that these methods do require analytical conditions to converge well, justifying existing heuristics.","lang":"eng"}],"oa_version":"Preprint","language":[{"iso":"eng"}],"page":"5973-5983","main_file_link":[{"url":"https://arxiv.org/abs/1809.10505","open_access":"1"}],"article_processing_charge":"No","quality_controlled":"1","volume":"Volume 2018","status":"public","type":"conference"},{"project":[{"name":"Random matrices, universality and disordered quantum systems","grant_number":"338804","_id":"258DCDE6-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"date_published":"2018-06-14T00:00:00Z","arxiv":1,"article_number":"543-616","isi":1,"department":[{"_id":"LaEr"}],"scopus_import":"1","type":"journal_article","status":"public","intvolume":" 171","volume":171,"quality_controlled":"1","article_processing_charge":"No","main_file_link":[{"url":"https://arxiv.org/abs/1605.08767","open_access":"1"}],"language":[{"iso":"eng"}],"oa_version":"Preprint","abstract":[{"text":"We consider spectral properties and the edge universality of sparse random matrices, the class of random matrices that includes the adjacency matrices of the Erdős–Rényi graph model G(N, p).

Patient fibroblasts were used to study splicing defect and zebrafish to model the disease.\r\n\r\nResults: We identified six individuals from three unrelated families with a founder homozygous splice mutation in TRAPPC6B, encoding a core subunit of the complex TRAPP I. Patients manifested a neurodevelopmental disorder characterised by microcephaly, epilepsy and autistic features, and showed splicing defect. Zebrafish trappc6b morphants replicated the human phenotype, displaying decreased head size and neuronal hyperexcitability, leading to a lower seizure threshold.\r\n\r\nConclusion: This study provides clinical and functional evidence of the role of TRAPPC6B in brain development and function.","lang":"eng"}],"oa_version":"Submitted Version","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6056005/","open_access":"1"}],"language":[{"iso":"eng"}],"page":"48 - 54","type":"journal_article","status":"public","volume":55,"intvolume":" 55"},{"isi":1,"department":[{"_id":"HeEd"}],"scopus_import":"1","has_accepted_license":"1","date_published":"2018-06-01T00:00:00Z","project":[{"name":"International IST Postdoc Fellowship Programme","grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7"}],"license":"https://creativecommons.org/licenses/by/4.0/","oa_version":"Published Version","page":"55 - 64","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"We consider families of confocal conics and two pencils of Apollonian circles having the same foci.

Social animals could potentially further reduce epidemic risk by altering their social networks in the presence of pathogens, yet there is currently no evidence for such pathogen-triggered responses. We tested this hypothesis experimentally in the ant Lasius niger using a combination of automated tracking, controlled pathogen exposure, transmission quantification, and temporally explicit simulations. Pathogen exposure induced behavioral changes in both exposed ants and their nestmates, which helped contain the disease by reinforcing key transmission-inhibitory properties of the colony's contact network. This suggests that social network plasticity in response to pathogens is an effective strategy for mitigating the effects of disease in social groups."}],"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://serval.unil.ch/resource/serval:BIB_E9228C205467.P001/REF.pdf"}],"language":[{"iso":"eng"}],"page":"941 - 945","year":"2018","date_updated":"2025-04-15T08:20:52Z","publisher":"AAAS","publication":"Science","title":"Social network plasticity decreases disease transmission in a eusocial insect","publication_identifier":{"issn":["1095-9203"]},"citation":{"ista":"Stroeymeyt N, Grasse AV, Crespi A, Mersch D, Cremer S, Keller L. 2018.

In order to understand precise functions of pre- or postsynaptic dopamine receptors (DRs), the development of protocols to differentiate pre- and postsynaptic DRs is essential. So far, most studies on determination and quantification of DRs did not discriminate between subsynaptic localization. Therefore, the aim of the study was to generate a robust workflow for the localization of DRs. This work provides the basis for future work on hippocampal DRs, in light that DRs may have different functions at pre- or postsynaptic sites. Synaptosomes from rat hippocampi isolated by a sucrose gradient protocol were prepared for super-resolution direct stochastic optical reconstruction microscopy (dSTORM) using Bassoon as a presynaptic zone and Homer1 as postsynaptic density marker. Direct labeling of primary validated antibodies against dopamine receptors D1 (D1R) and D2 (D2R) with Alexa Fluor 594 enabled unequivocal assignment of D1R and D2R to both, pre- and postsynaptic sites. D1R immunoreactivity clusters were observed within the presynaptic active zone as well as at perisynaptic sites at the edge of the presynaptic active zone. The results may be useful for the interpretation of previous studies and the design of future work on DRs in the hippocampus. Moreover, the reduction of the complexity of brain tissue by the use of synaptosomal preparations and dSTORM technology may represent a useful tool for synaptic localization of brain proteins.","lang":"eng"}],"status":"public","type":"journal_article","intvolume":" 55","volume":55,"external_id":{"isi":["000431991500025"]},"citation":{"apa":"Miklosi, A., Del Favero, G., Bulat, T., Höger, H., Shigemoto, R., Marko, D., & Lubec, G.

In particular, there has been intensive research on reducing the communication cost of training when using multiple computational devices, through reducing the precision of the underlying data representation. Naturally, such methods induce system trade-offs—lowering communication precision could de-crease communication overheads and improve scalability; but, on the other hand, it can also reduce the accuracy of training. In this paper, we study this trade-off space, and ask:Can low-precision communication consistently improve the end-to-end performance of training modern neural networks, with no accuracy loss?From the performance point of view, the answer to this question may appear deceptively easy: compressing communication through low precision should help when the ratio between communication and computation is high. However, this answer is less straightforward when we try to generalize this principle across various neural network architectures (e.g., AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g., EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL), and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is not clear how a realistic realization of all these factors maps to the speed up provided by low-precision communication. In this paper, we conduct an empirical study to answer this question and report the insights."}],"file_date_updated":"2020-07-14T12:47:49Z","quality_controlled":"1","article_processing_charge":"No","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"status":"public","type":"conference","department":[{"_id":"DaAl"}],"scopus_import":1,"has_accepted_license":"1","date_published":"2018-03-26T00:00:00Z","date_created":"2019-11-26T14:19:11Z","ddc":["000"],"oa":1,"conference":{"name":"EDBT: Conference on Extending Database Technology","location":"Vienna, Austria","end_date":"2018-03-29","start_date":"2018-03-26"},"day":"26","_id":"7116","file":[{"file_name":"2018_OpenProceedings_Grubic.pdf","file_id":"7118","date_updated":"2020-07-14T12:47:49Z","access_level":"open_access","date_created":"2019-11-26T14:23:04Z","relation":"main_file","file_size":1603204,"content_type":"application/pdf","checksum":"ec979b56abc71016d6e6adfdadbb4afe","creator":"dernst"}],"publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"03","doi":"10.5441/002/EDBT.2018.14","author":[{"last_name":"Grubic","full_name":"Grubic, Demjan","first_name":"Demjan"},{"full_name":"Tam, Leo","last_name":"Tam","first_name":"Leo"},{"orcid":"0000-0003-3650-940X","first_name":"Dan-Adrian","full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","last_name":"Alistarh"},{"last_name":"Zhang","full_name":"Zhang, Ce","first_name":"Ce"}],"citation":{"mla":"Grubic, Demjan, et al. “Synchronous Multi-GPU Training for Deep Learning with Low-Precision Communications: An Empirical Study.” Proceedings of the 21st International Conference on Extending Database Technology, OpenProceedings, 2018, pp. 145–56, doi:10.5441/002/EDBT.2018.14.","ieee":"D.

Inspired by recent developments in DNA programming, an extensive series of papers, across different communities, has examined the computability and complexity characteristics of this model. Majority, or consensus, is a central task in this model, in which agents need to collectively reach a decision as to which one of two states A or B had a higher initial count. Two metrics are important: the time that a protocol requires to stabilize to an output decision, and the state space size that each agent requires to do so. It is known that majority requires Ω(log log n) states per agent to allow for fast (poly-logarithmic time) stabilization, and that O(log2 n) states are sufficient. Thus, there is an exponential gap between the space upper and lower bounds for this problem. This paper addresses this question.\r\n\r\nOn the negative side, we provide a new lower bound of Ω(log n) states for any protocol which stabilizes in O(n1–c) expected time, for any constant c > 0. This result is conditional on monotonicity and output assumptions, satisfied by all known protocols. Technically, it represents a departure from previous lower bounds, in that it does not rely on the existence of dense configurations. Instead, we introduce a new generalized surgery technique to prove the existence of incorrect executions for any algorithm which would contradict the lower bound. Subsequently, our lower bound also applies to general initial configurations, including ones with a leader. On the positive side, we give a new algorithm for majority which uses O(log n) states, and stabilizes in O(log2 n) expected time. Central to the algorithm is a new leaderless phase clock technique, which allows agents to synchronize in phases of Θ(n log n) consecutive interactions using O(log n) states per agent, exploiting a new connection between population protocols and power-of-two-choices load balancing mechanisms. We also employ our phase clock to build a leader election algorithm with a state space of size O(log n), which stabilizes in O(log2 n) expected time."}],"date_published":"2018-01-30T00:00:00Z","arxiv":1,"department":[{"_id":"DaAl"}],"isi":1,"scopus_import":"1","publication_status":"published","conference":{"end_date":"2018-01-10","start_date":"2018-01-07","name":"SODA: Symposium on Discrete Algorithms","location":"New Orleans, LA, United States"},"day":"30","_id":"7123","date_created":"2019-11-26T15:10:55Z","oa":1,"publication":"Proceedings of the 29th Annual ACM-SIAM Symposium on Discrete Algorithms","year":"2018","date_updated":"2024-10-21T06:02:41Z","publisher":"ACM","title":"Space-optimal majority in population protocols","publication_identifier":{"isbn":["9781611975031"]},"external_id":{"isi":["000483921200145"],"arxiv":["1704.04947"]},"citation":{"mla":"Alistarh, Dan-Adrian, et al. “Space-Optimal Majority in Population Protocols.” Proceedings of the 29th Annual ACM-SIAM Symposium on Discrete Algorithms, ACM, 2018, pp. 2221–39, doi:10.1137/1.9781611975031.144.","ieee":"D.-A.

Using the metaphor of a fitness landscape, local optima correspond to hills separated by fitness valleys that have to be overcome. We define a class of fitness valleys of tunable difficulty by considering their length, representing the Hamming path between the two optima and their depth, the drop in fitness. For this function class we present a runtime comparison between stochastic search algorithms using different search strategies. The (1+1) EA is a simple and well-studied evolutionary algorithm that has to jump across the valley to a point of higher fitness because it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population genetics, are both able to cross the fitness valley by accepting worsening moves. We show that the runtime of the (1+1) EA depends critically on the length of the valley while the runtimes of the non-elitist algorithms depend crucially on the depth of the valley. Moreover, we show that both SSWM and Metropolis can also efficiently optimise a rugged function consisting of consecutive valleys."}],"file_date_updated":"2020-07-14T12:47:54Z","status":"public","type":"journal_article","volume":80,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"intvolume":" 80","has_accepted_license":"1","date_published":"2018-05-01T00:00:00Z","isi":1,"department":[{"_id":"NiBa"},{"_id":"CaGu"}],"scopus_import":"1","project":[{"_id":"25B1EC9E-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Speed of Adaptation in Population Genetics and Evolutionary Computation","grant_number":"618091"}],"ec_funded":1,"day":"01","_id":"723","date_created":"2018-12-11T11:48:09Z","ddc":["576"],"pubrep_id":"1014","oa":1,"file":[{"content_type":"application/pdf","creator":"system","checksum":"7d92f5d7be81e387edeec4f06442791c","file_size":691245,"relation":"main_file","date_created":"2018-12-12T10:08:14Z","access_level":"open_access","date_updated":"2020-07-14T12:47:54Z","file_name":"IST-2018-1014-v1+1_2018_Paixao_Escape.pdf","file_id":"4674"}],"issue":"5","publication_status":"published","external_id":{"isi":["000428239300010"]},"citation":{"mla":"Oliveto, Pietro, et al. “How to Escape Local Optima in Black Box Optimisation When Non Elitism Outperforms Elitism.” Algorithmica, vol. 80, no. 5, Springer, 2018, pp. 1604–33, doi:10.1007/s00453-017-0369-2.","ieee":"P.

Given such a taskset T , the competitive ratio of an on-line scheduling algorithm A for T is the worst-case utility ratio of A over the utility achieved by a clairvoyant algorithm. We leverage the theory of quantitative graph games to address the competitive analysis and competitive synthesis problems. For the competitive analysis case, given any taskset T and any finite-memory on- line scheduling algorithm A , we show that the competitive ratio of A in T can be computed in polynomial time in the size of the state space of A . Our approach is flexible as it also provides ways to model meaningful constraints on the released task sequences that determine the competitive ratio. We provide an experimental study of many well-known on-line scheduling algorithms, which demonstrates the feasibility of our competitive analysis approach that effectively replaces human ingenuity (required Preliminary versions of this paper have appeared in Chatterjee et al.

For the competitive synthesis case, we are just given a taskset T , and the goal is to automatically synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees the largest competitive ratio possible for T . We show how the competitive synthesis problem can be reduced to a two-player graph game with partial information, and establish that the compu- tational complexity of solving this game is Np -complete. The competitive synthesis problem is hence in Np in the size of the state space of the non-deterministic labeled transition system encoding the taskset. Overall, the proposed framework assists in the selection of suitable scheduling algorithms for a given taskset, which is in fact the most common situation in real-time systems design.

PoS were introduced as a more ecological and economical replacement for proofs of work which are currently used to secure blockchains like Bitcoin. In this work we investigate extensions of PoS which allow the prover to embed useful data into the dedicated space, which later can be recovered. Our first contribution is a security proof for the original PoS from CRYPTO'15 in the random oracle model (the original proof only applied to a restricted class of adversaries which can store a subset of the data an honest prover would store). When this PoS is instantiated with recent constructions of maximally depth robust graphs, our proof implies basically optimal security. As a second contribution we show three different extensions of this PoS where useful data can be embedded into the space required by the prover. Our security proof for the PoS extends (non-trivially) to these constructions. We discuss how some of these variants can be used as proofs of catalytic space (PoCS), a notion we put forward in this work, and which basically is a PoS where most of the space required by the prover can be used to backup useful data. Finally we discuss how one of the extensions is a candidate construction for a proof of replication (PoR), a proof system recently suggested in the Filecoin whitepaper.

In the self-stabilising firing squad problem, the task is to eventually guarantee that all non-faulty nodes have simultaneous responses to external inputs: if a subset of the correct nodes receive an external “go” signal as input, then all correct nodes should agree on a round (in the not-too-distant future) in which to jointly output a “fire” signal. Moreover, no node should generate a “fire” signal without some correct node having previously received a “go” signal as input. We present a framework reducing both tasks to binary consensus at very small cost. For example, we obtain a deterministic algorithm for self-stabilising Byzantine firing squads with optimal resilience f<n/3, asymptotically optimal stabilisation and response time O(f), and message size O(log f).

However, biases in discovery and reporting of inversions make it difficult to assess their prevalence and biological importance. Here, we use an approach based on linkage disequilibrium among markers genotyped for samples collected across a transect between contrasting habitats to detect chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in a single locality for the coastal marine snail, Littorina saxatilis. Patterns of diversity in the field and of recombination in controlled crosses provide strong evidence that at least the majority of these rearrangements are inversions. Most show clinal changes in frequency between habitats, suggestive of divergent selection, but only one appears to be fixed for different arrangements in the two habitats. Consistent with widespread evidence for balancing selection on inversion polymorphisms, we argue that a combination of heterosis and divergent selection can explain the observed patterns and should be considered in other systems spanning environmental gradients.","lang":"eng"}],"oa":1,"status":"public","type":"research_data_reference","related_material":{"record":[{"id":"6095","relation":"used_in_publication","status":"public"}]},"citation":{"ama":"Faria R, Chaube P, Morales HE, et al.

Facial features reflect the underlying geometry of the skeletal structures. Here we reveal that cartilaginous nasal capsule (corresponding to upper jaw and face) is shaped by signals generated by neural structures: brain and olfactory epithelium. Brain-derived Sonic Hedgehog (SHH) enables the induction of nasal septum and posterior nasal capsule, whereas the formation of a capsule roof is controlled by signals from the olfactory epithelium. Unexpectedly, the cartilage of the nasal capsule turned out to be important for shaping membranous facial bones during development. This suggests that conserved neurosensory structures could benefit from protection and have evolved signals inducing cranial cartilages encasing them. Experiments with mutant mice revealed that the genomic regulatory regions controlling production of SHH in the nervous system contribute to facial cartilage morphogenesis, which might be a mechanism responsible for the adaptive evolution of animal faces and snouts.","lang":"eng"}],"oa":1,"day":"14","_id":"9838","article_processing_charge":"No","title":"Data from: Signals from the brain and olfactory epithelium control shaping of the mammalian nasal capsule cartilage","year":"2018","publisher":"Dryad","date_updated":"2025-04-14T13:02:22Z","department":[{"_id":"AnKi"}],"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","month":"06","doi":"10.5061/dryad.f1s76f2","author":[{"first_name":"Marketa","full_name":"Kaucka, Marketa","last_name":"Kaucka"},{"first_name":"Julian","last_name":"Petersen","full_name":"Petersen, Julian"},{"first_name":"Marketa","full_name":"Tesarova, Marketa","last_name":"Tesarova"},{"full_name":"Szarowska, Bara","last_name":"Szarowska","first_name":"Bara"},{"first_name":"Maria Eleni","full_name":"Kastriti, Maria Eleni","last_name":"Kastriti"},{"last_name":"Xie","full_name":"Xie, Meng","first_name":"Meng"},{"full_name":"Kicheva, Anna","id":"3959A2A0-F248-11E8-B48F-1D18A9856A87","last_name":"Kicheva","first_name":"Anna","orcid":"0000-0003-4509-4998"},{"full_name":"Annusver, Karl","last_name":"Annusver","first_name":"Karl"},{"first_name":"Maria","full_name":"Kasper, Maria","last_name":"Kasper"},{"first_name":"Orsolya","last_name":"Symmons","full_name":"Symmons, Orsolya"},{"last_name":"Pan","full_name":"Pan, Leslie","first_name":"Leslie"},{"first_name":"Francois","full_name":"Spitz, Francois","last_name":"Spitz"},{"full_name":"Kaiser, Jozef","last_name":"Kaiser","first_name":"Jozef"},{"first_name":"Maria","full_name":"Hovorakova, Maria","last_name":"Hovorakova"},{"first_name":"Tomas","full_name":"Zikmund, Tomas","last_name":"Zikmund"},{"first_name":"Kazunori","last_name":"Sunadome","full_name":"Sunadome, Kazunori"},{"full_name":"Matise, Michael P","last_name":"Matise","first_name":"Michael P"},{"first_name":"Hui","last_name":"Wang","full_name":"Wang, Hui"},{"full_name":"Marklund, Ulrika","last_name":"Marklund","first_name":"Ulrika"},{"first_name":"Hind","full_name":"Abdo, Hind","last_name":"Abdo"},{"first_name":"Patrik","full_name":"Ernfors, Patrik","last_name":"Ernfors"},{"full_name":"Maire, Pascal","last_name":"Maire","first_name":"Pascal"},{"first_name":"Maud","last_name":"Wurmser","full_name":"Wurmser, Maud"},{"full_name":"Chagin, Andrei S","last_name":"Chagin","first_name":"Andrei S"},{"last_name":"Fried","full_name":"Fried, Kaj","first_name":"Kaj"},{"last_name":"Adameyko","full_name":"Adameyko, Igor","first_name":"Igor"}],"citation":{"short":"M.

Here, we report the 2-Gb genome of the German cockroach, Blattella germanica, and the 1.3-Gb genome of the drywood termite Cryptotermes secundus. We show evolutionary signatures of termite eusociality by comparing the genomes and transcriptomes of three termites and the cockroach against the background of 16 other eusocial and non-eusocial insects. Dramatic adaptive changes in genes underlying the production and perception of pheromones confirm the importance of chemical communication in the termites. These are accompanied by major changes in gene regulation and the molecular evolution of caste determination. Many of these results parallel molecular mechanisms of eusocial evolution in Hymenoptera. However, the specific solutions are remarkably different, thus revealing a striking case of convergence in one of the major evolutionary transitions in biological complexity.","lang":"eng"}],"oa":1},{"department":[{"_id":"BeVi"}],"isi":1,"scopus_import":"1","has_accepted_license":"1","acknowledgement":"The authors express a special thanks to Dr Richard Willan at the Museum and Art Gallery of the Northern Territory for guidance and support in the field, and to Carole Smadja for reading and commenting on the manuscript.

Stronger assortment, or greater divergence in mating traits, between species pairs with overlapping ranges is commonly observed, but possible causes of this pattern of reproductive character displacement are difficult to distinguish. We use a multidisciplinary approach to provide a rare example where it is possible to distinguish among hypotheses concerning the evolution of reproductive character displacement. We build on an earlier comparative analysis that illustrated a strong pattern of greater divergence in penis form between pairs of sister species with overlapping ranges than between allopatric sister-species pairs, in a large clade of marine gastropods (Littorinidae). We investigate both assortative mating and divergence in male genitalia in one of the sister-species pairs, discriminating among three contrasting processes each of which can generate a pattern of reproductive character displacement: reinforcement, reproductive interference and the Templeton effect. We demonstrate reproductive character displacement in assortative mating, but not in genital form between this pair of sister species and use demographic models to distinguish among the different processes. Our results support a model with no gene flow since secondary contact and thus favor reproductive interference as the cause of reproductive character displacement for mate choice, rather than reinforcement. High gene flow within species argues against the Templeton effect. Secondary contact appears to have had little impact on genital divergence."}],"file_date_updated":"2021-08-16T07:37:28Z","article_type":"letter_note","quality_controlled":"1","article_processing_charge":"Yes","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"related_material":{"record":[{"id":"9929","relation":"research_data","status":"public"}]},"volume":2,"intvolume":" 2","status":"public","type":"journal_article","month":"12","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"first_name":"Johan","full_name":"Hollander, Johan","last_name":"Hollander"},{"first_name":"Mauricio","last_name":"Montaño-Rendón","full_name":"Montaño-Rendón, Mauricio"},{"full_name":"Bianco, Giuseppe","last_name":"Bianco","first_name":"Giuseppe"},{"last_name":"Yang","full_name":"Yang, Xi","first_name":"Xi"},{"first_name":"Anja M","orcid":"0000-0003-1050-4969","last_name":"Westram","full_name":"Westram, Anja M","id":"3C147470-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ludovic","last_name":"Duvaux","full_name":"Duvaux, Ludovic"},{"first_name":"David G.","last_name":"Reid","full_name":"Reid, David G."},{"last_name":"Butlin","full_name":"Butlin, Roger K.","first_name":"Roger K."}],"doi":"10.1002/evl3.85","citation":{"short":"J.
