However, ice cliff contribution is difficult to quantify as they are highly dynamic features, and the paucity of observations of melt rates and their variability leads to large modelling uncertainties. We quantify monsoon season melt and 3D evolution of four ice cliffs over two debris-covered glaciers in High Mountain Asia (Langtang Glacier, Nepal, and 24K Glacier, China) at very high resolution using terrestrial photogrammetry applied to imagery captured from time-lapse cameras installed on lateral moraines. We derive weekly flow-corrected digital elevation models (DEMs) of the glacier surface with a maximum vertical bias of ±0.2 m for Langtang Glacier and ±0.05 m for 24K Glacier and use change detection to determine distributed melt rates at the surfaces of the ice cliffs throughout the study period. We compare the measured melt patterns with those derived from a 3D energy balance model to derive the contribution of the main energy fluxes. We find that ice cliff melt varies considerably throughout the melt season, with maximum melt rates of 5 to 8 cm d−1, and their average melt rates are 11–14 (Langtang) and 4.5 (24K) times higher than the surrounding debris-covered ice. Our results highlight the influence of redistributed supraglacial debris on cliff melt. At both sites, ice cliff albedo is influenced by the presence of thin debris at the ice cliff surface, which is largely controlled on 24K Glacier by liquid precipitation events that wash away this debris. Slightly thicker or patchy debris reduces melt by 1–3 cm d−1 at all sites. Ultimately, our observations show a strong spatio-temporal variability in cliff area at each site, which is controlled by supraglacial streams and ponds and englacial cavities that promote debris slope destabilisation and the lateral expansion of the cliffs. These findings highlight the need to better represent processes of debris redistribution in ice cliff models, to in turn improve estimates of ice cliff contribution to glacier melt and the long-term geomorphological evolution of debris-covered glacier surfaces.","lang":"eng"}],"author":[{"last_name":"Kneib","full_name":"Kneib, Marin","first_name":"Marin"},{"last_name":"Miles","full_name":"Miles, Evan S.","first_name":"Evan S."},{"full_name":"Buri, Pascal","last_name":"Buri","first_name":"Pascal"},{"first_name":"Stefan","last_name":"Fugger","full_name":"Fugger, Stefan"},{"first_name":"Michael","full_name":"McCarthy, Michael","last_name":"McCarthy"},{"last_name":"Shaw","full_name":"Shaw, Thomas E.","first_name":"Thomas E."},{"full_name":"Chuanxi, Zhao","last_name":"Chuanxi","first_name":"Zhao"},{"first_name":"Martin","last_name":"Truffer","full_name":"Truffer, Martin"},{"last_name":"Westoby","full_name":"Westoby, Matthew J.","first_name":"Matthew J."},{"last_name":"Yang","full_name":"Yang, Wei","first_name":"Wei"},{"full_name":"Pellicciotti, Francesca","last_name":"Pellicciotti","first_name":"Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70"}],"title":"Sub-seasonal variability of supraglacial ice cliff melt rates and associated processes from time-lapse photogrammetry","day":"11","publication":"The Cryosphere","publication_identifier":{"issn":["1994-0424"]},"article_processing_charge":"No","main_file_link":[{"url":"https://doi.org/10.5194/tc-16-4701-2022","open_access":"1"}],"date_created":"2023-02-20T08:09:42Z","status":"public","publication_status":"published","citation":{"ama":"Kneib M, Miles ES, Buri P, et al.

Enhanced energy absorption at ice cliffs and supraglacial ponds scattered across the debris surface leads these features to contribute disproportionately to glacier-wide ablation. However, the degree to which cliffs and ponds actually increase melt rates remains unclear, as these features have only been studied in a detailed manner for selected locations, almost exclusively in High Mountain Asia. In this study we model the surface energy balance for debris-covered ice, ice cliffs, and supraglacial ponds with a set of automatic weather station records representing the global prevalence of debris-covered glacier ice. We generate 5000 random sets of values for physical parameters using probability distributions derived from literature, which we use to investigate relative melt rates and to isolate the melt responses of debris, cliffs and ponds to the site-specific meteorological forcing. Modelled sub-debris melt rates are primarily controlled by debris thickness and thermal conductivity. At a reference thickness of 0.1 m, sub-debris melt rates vary considerably, differing by up to a factor of four between sites, mainly attributable to air temperature differences. We find that melt rates for ice cliffs are consistently 2–3× the melt rate for clean glacier ice, but this melt enhancement decays with increasing clean ice melt rates. Energy absorption at supraglacial ponds is dominated by latent heat exchange and is therefore highly sensitive to wind speed and relative humidity, but is generally less than for clean ice. Our results provide reference melt enhancement factors for melt modelling of debris-covered glacier sites, globally, while highlighting the need for direct measurement of debris-covered glacier surface characteristics, physical parameters, and local meteorological conditions at a variety of sites around the world.","lang":"eng"}],"intvolume":"        17","date_updated":"2023-02-28T13:34:25Z","article_number":"064004","oa_version":"Published Version","status":"public","date_created":"2023-02-20T08:10:37Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1088/1748-9326/ac6966"}],"article_processing_charge":"No","publication_identifier":{"issn":["1748-9326"]},"publication":"Environmental Research Letters","scopus_import":"1","month":"06","_id":"12582","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":17,"type":"journal_article","citation":{"short":"E.S.

Here, we apply our recently developed Bayesian grouped mixture of regressions model (GMRM) in the UK and Estonian Biobanks and obtain the highest genomic prediction accuracy reported to date across 21 heritable traits. When compared to other approaches, GMRM accuracy was greater than annotation prediction models run in the LDAK or LDPred-funct software by 15% (SE 7%) and 14% (SE 2%), respectively, and was 18% (SE 3%) greater than a baseline BayesR model without single-nucleotide polymorphism (SNP) markers grouped into minor allele frequency–linkage disequilibrium (MAF-LD) annotation categories. For height, the prediction accuracy R 2 was 47% in a UK Biobank holdout sample, which was 76% of the estimated h SNP 2 . We then extend our GMRM prediction model to provide mixed-linear model association (MLMA) SNP marker estimates for genome-wide association (GWAS) discovery, which increased the independent loci detected to 16,162 in unrelated UK Biobank individuals, compared to 10,550 from BoltLMM and 10,095 from Regenie, a 62 and 65% increase, respectively. The average χ2 value of the leading markers increased by 15.24 (SE 0.41) for every 1% increase in prediction accuracy gained over a baseline BayesR model across the traits. Thus, we show that modeling genetic associations accounting for MAF and LD differences among SNP markers, and incorporating prior knowledge of genomic function, is important for both genomic prediction and discovery in large-scale individual-level studies.","lang":"eng"}],"corr_author":"1","date_updated":"2025-06-12T06:22:36Z","citation":{"ista":"Orliac E, Trejo Banos D, Ojavee S, Läll K, Mägi R, Visscher P, Robinson MR. 2022.

Chiral metasurfaces increase the electronic sensitivity to circular polarization, but their out-of-plane architecture entails manufacturing and performance trade-offs. Here, we show that nanoporous thin films of chiral nanoparticles enable high sensitivity to circular polarization due to light-induced polarization-dependent ion accumulation at nanoparticle interfaces. Self-assembled multilayers of gold nanoparticles modified with L-phenylalanine generate a photocurrent under right-handed circularly polarized light as high as 2.41 times higher than under left-handed circularly polarized light. The strong plasmonic coupling between the multiple nanoparticles producing planar chiroplasmonic modes facilitates the ejection of electrons, whose entrapment at the membrane–electrolyte interface is promoted by a thick layer of enantiopure phenylalanine. Demonstrated detection of light ellipticity with equal sensitivity at all incident angles mimics phenomenological aspects of polarization vision in marine animals.

General\r\npurpose models typically make few assumptions about the underlying\r\ndata-structure and are known to perform well in the large-data regime. At the\r\nsame time, there has been growing interest in modular neural architectures that\r\nrepresent the data using sparsely interacting modules. These models can be more\r\nrobust out-of-distribution, computationally efficient, and capable of\r\nsample-efficient adaptation to new data. However, they tend to make\r\ndomain-specific assumptions about the data, and present challenges in how\r\nmodule behavior (i.e., parameterization) and connectivity (i.e., their layout)\r\ncan be jointly learned. In this work, we introduce a general purpose, yet\r\nmodular neural architecture called Neural Attentive Circuits (NACs) that\r\njointly learns the parameterization and a sparse connectivity of neural modules\r\nwithout using domain knowledge. NACs are best understood as the combination of\r\ntwo systems that are jointly trained end-to-end: one that determines the module\r\nconfiguration and the other that executes it on an input. We demonstrate\r\nqualitatively that NACs learn diverse and meaningful module configurations on\r\nthe NLVR2 dataset without additional supervision. Quantitatively, we show that\r\nby incorporating modularity in this way, NACs improve upon a strong non-modular\r\nbaseline in terms of low-shot adaptation on CIFAR and CUBs dataset by about\r\n10%, and OOD robustness on Tiny ImageNet-R by about 2.5%. Further, we find that\r\nNACs can achieve an 8x speedup at inference time while losing less than 3%\r\nperformance. Finally, we find NACs to yield competitive results on diverse data\r\nmodalities spanning point-cloud classification, symbolic processing and\r\ntext-classification from ASCII bytes, thereby confirming its general purpose\r\nnature."}],"volume":35,"type":"conference","author":[{"first_name":"Nasim","full_name":"Rahaman, Nasim","last_name":"Rahaman"},{"first_name":"Martin","last_name":"Weiss","full_name":"Weiss, Martin"},{"id":"26cfd52f-2483-11ee-8040-88983bcc06d4","first_name":"Francesco","orcid":"0000-0002-4850-0683","last_name":"Locatello","full_name":"Locatello, Francesco"},{"full_name":"Pal, Chris","last_name":"Pal","first_name":"Chris"},{"first_name":"Yoshua","last_name":"Bengio","full_name":"Bengio, Yoshua"},{"last_name":"Schölkopf","full_name":"Schölkopf, Bernhard","first_name":"Bernhard"},{"first_name":"Li Erran","full_name":"Li, Li Erran","last_name":"Li"},{"first_name":"Nicolas","last_name":"Ballas","full_name":"Ballas, Nicolas"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14168","department":[{"_id":"FrLo"}],"title":"Neural attentive circuits","arxiv":1,"alternative_title":[" Advances in Neural Information Processing Systems"],"month":"10","day":"14"},{"year":"2022","publication":"arXiv","related_material":{"record":[{"id":"17481","relation":"later_version","status":"public"},{"status":"public","id":"14587","relation":"dissertation_contains"}]},"ec_funded":1,"external_id":{"arxiv":["2203.17143"]},"article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2203.17143"}],"date_created":"2023-11-23T09:30:02Z","oa":1,"status":"public","doi":"10.48550/ARXIV.2203.17143","date_published":"2022-03-31T00:00:00Z","language":[{"iso":"eng"}],"oa_version":"Preprint","article_number":"2203.17143","publication_status":"draft","date_updated":"2026-04-07T13:28:13Z","citation":{"short":"J.L.

In its sharp-interface limit, the vectorial Allen-Cahn equation with a potential with N≥3 distinct minima has been conjectured to describe the evolution of branched interfaces by multiphase mean curvature flow.\r\nIn the present work, we give a rigorous proof for this statement in two and three ambient dimensions and for a suitable class of potentials: As long as a strong solution to multiphase mean curvature flow exists, solutions to the vectorial Allen-Cahn equation with well-prepared initial data converge towards multiphase mean curvature flow in the limit of vanishing interface width parameter ε↘0. We even establish the rate of convergence O(ε1/2).\r\nOur approach is based on the gradient flow structure of the Allen-Cahn equation and its limiting motion: Building on the recent concept of \"gradient flow calibrations\" for multiphase mean curvature flow, we introduce a notion of relative entropy for the vectorial Allen-Cahn equation with multi-well potential. This enables us to overcome the limitations of other approaches, e.g. avoiding the need for a stability analysis of the Allen-Cahn operator or additional convergence hypotheses for the energy at positive times.","lang":"eng"}],"corr_author":"1","author":[{"full_name":"Fischer, Julian L","last_name":"Fischer","orcid":"0000-0002-0479-558X","first_name":"Julian L","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Marveggio, Alice","last_name":"Marveggio","id":"25647992-AA84-11E9-9D75-8427E6697425","first_name":"Alice"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14597","department":[{"_id":"JuFi"}],"project":[{"name":"Bridging Scales in Random Materials","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","call_identifier":"H2020","grant_number":"948819"}],"title":"Quantitative convergence of the vectorial Allen-Cahn equation towards multiphase mean curvature flow","arxiv":1,"day":"31","month":"03"},{"status":"public","date_created":"2023-11-24T13:10:09Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2210.05308"}],"article_processing_charge":"No","ec_funded":1,"publication":"arXiv","related_material":{"record":[{"relation":"later_version","id":"14830","status":"public"},{"status":"public","id":"14539","relation":"dissertation_contains"}]},"title":"Learning control policies for stochastic systems with reach-avoid guarantees","day":"29","project":[{"grant_number":"863818","call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"name":"Vigilant Algorithmic Monitoring of Software","call_identifier":"H2020","grant_number":"101020093","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"name":"International IST Doctoral Program","grant_number":"665385","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"department":[{"_id":"KrCh"},{"_id":"ToHe"}],"license":"https://creativecommons.org/licenses/by-sa/4.0/","author":[{"last_name":"Zikelic","full_name":"Zikelic, Dorde","first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4681-1699"},{"id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias","full_name":"Lechner, Mathias","last_name":"Lechner"},{"last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas A","orcid":"0000-0002-2985-7724"},{"last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X"}],"date_updated":"2026-04-07T13:27:56Z","article_number":"2210.05308","oa_version":"Preprint","abstract":[{"lang":"eng","text":"We study the problem of learning controllers for discrete-time non-linear stochastic dynamical systems with formal reach-avoid guarantees.

Our method leverages advances in machine learning literature and it represents formal certificates as neural networks. In particular, we learn a certificate in the form of a reach-avoid supermartingale (RASM), a novel notion that we introduce in this work. Our RASMs provide reachability and avoidance guarantees by imposing constraints on what can be viewed as a stochastic extension of level sets of Lyapunov functions for deterministic systems. Our approach solves several important problems -- it can be used to learn a control policy from scratch, to verify a reach-avoid specification for a fixed control policy, or to fine-tune a pre-trained policy if it does not satisfy the reach-avoid specification.

Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with propagation of photons in the presence of the strong magnetic field. Here we present results of the observations of Cen X-3 performed with the Imaging X-ray Polarimetry Explorer. The source exhibited significant flux variability and was observed in two states different by a factor of ∼20 in flux. In the low-luminosity state, no significant polarization was found in either pulse phase-averaged (with a 3σ upper limit of 12%) or phase-resolved (the 3σ upper limits are 20%–30%) data. In the bright state, the polarization degree of 5.8% ± 0.3% and polarization angle of 49fdg6 ± 1fdg5 with a significance of about 20σ were measured from the spectropolarimetric analysis of the phase-averaged data. The phase-resolved analysis showed a significant anticorrelation between the flux and the polarization degree, as well as strong variations of the polarization angle. The fit with the rotating vector model indicates a position angle of the pulsar spin axis of about 49° and a magnetic obliquity of 17°. The detected relatively low polarization can be explained if the upper layers of the neutron star surface are overheated by the accreted matter and the conversion of the polarization modes occurs within the transition region between the upper hot layer and a cooler underlying atmosphere. A fraction of polarization signal can also be produced by reflection of radiation from the neutron star surface and the accretion curtain.","lang":"eng"}],"article_number":"L14","oa_version":"Published Version","date_updated":"2024-04-02T07:16:18Z","intvolume":"       941"},{"article_processing_charge":"Yes","acknowledgement":"We thank members of the Conradt, Lambie, and Hajnal labs for discussions and comments on the manuscript.

But how is cell size controlled in this context and how does cell size impact commitment to the cell death fate? We present evidence that the caspase CED-3 interacts with the RhoGEF ECT-2 in Caenorhabditis elegans neuroblasts that generate “unwanted” cells. We propose that this interaction promotes polar actomyosin contractility, which leads to unequal neuroblast division and the generation of a daughter cell that is below the critical “lethal” size threshold. Furthermore, we find that hyperactivation of ECT-2 RhoGEF reduces the sizes of unwanted cells. Importantly, this suppresses the “cell death abnormal” phenotype caused by the partial loss of ced-3 caspase and therefore increases the likelihood that unwanted cells die. A putative null mutation of ced-3 caspase, however, is not suppressed, which indicates that cell size affects CED-3 caspase activation and/or activity. Therefore, we have uncovered novel sequential and reciprocal interactions between the apoptosis pathway and cell size that impact a cell’s commitment to the cell death fate."}],"oa_version":"Published Version","article_number":"e3001786","date_updated":"2024-08-06T07:08:54Z","intvolume":"        20","author":[{"last_name":"Sethi","full_name":"Sethi, Aditya","first_name":"Aditya"},{"full_name":"Wei, Hai","last_name":"Wei","first_name":"Hai"},{"orcid":"0000-0002-6425-5788","first_name":"Nikhil","id":"C4D70E82-1081-11EA-B3ED-9A4C3DDC885E","full_name":"Mishra, Nikhil","last_name":"Mishra"},{"last_name":"Segos","full_name":"Segos, Ioannis","first_name":"Ioannis"},{"first_name":"Eric J.","last_name":"Lambie","full_name":"Lambie, Eric J."},{"last_name":"Zanin","full_name":"Zanin, Esther","first_name":"Esther"},{"first_name":"Barbara","full_name":"Conradt, Barbara","last_name":"Conradt"}],"article_type":"original","language":[{"iso":"eng"}],"date_published":"2022-10-06T00:00:00Z","publisher":"Public Library of Science","doi":"10.1371/journal.pbio.3001786","issue":"10","file":[{"relation":"main_file","creator":"dernst","success":1,"date_created":"2024-08-06T07:07:52Z","content_type":"application/pdf","date_updated":"2024-08-06T07:07:52Z","file_size":2515388,"file_id":"17399","file_name":"2022_PlosBio_Sethi.pdf","access_level":"open_access","checksum":"a7b46460b7819c196028481cc18a7c85"}],"oa":1,"quality_controlled":"1","year":"2022","external_id":{"pmid":["36201522"]},"_id":"17066","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"pmid":1,"scopus_import":"1","month":"10","volume":20,"type":"journal_article","publication_status":"published","citation":{"short":"A.

It is famously encountered in suspensions of corn starch in water. Despite having been discovered in the early 1930's, its underlying mechanisms remained a mystery for a long time. In 2013–14, numerical and theoretical works [[1], [2], [3]] put forward a frictional transition scenario to explain this phenomenon.\r\nIn this talk, I will present experimental work investigating this frictional transition scenario. In order to test the ideas of this model, one has to go further than standard rheological techniques, since they do not provide access to the frictional state of the measured suspension. I will thus focus on the techniques that we developed in order to evidence the frictional transition and link it to the presence of a shear-thickening behaviour."}],"intvolume":"         3","date_updated":"2024-12-11T09:24:57Z","oa_version":"Published Version","article_number":"100038","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","author":[{"orcid":"0000-0002-1843-3803","id":"5f654c5d-04a1-11eb-ab36-ba9ffec58bd8","first_name":"Cécile","full_name":"Clavaud, Cécile","last_name":"Clavaud"}],"department":[{"_id":"ScWa"}],"OA_type":"gold","has_accepted_license":"1","day":"01","ddc":["530"],"title":"Shear thickening in dense suspensions: an experimental study","year":"2022","quality_controlled":"1","article_type":"original","doi":"10.1016/j.sctalk.2022.100038","date_published":"2022-08-01T00:00:00Z","publisher":"Elsevier","language":[{"iso":"eng"}],"oa":1,"file":[{"access_level":"open_access","checksum":"379a5f0b2684cd5393a23be374591484","file_name":"2022_ScienceTalks_Clavaud.pdf","file_id":"18607","file_size":1128564,"date_updated":"2024-12-03T08:41:48Z","content_type":"application/pdf","date_created":"2024-12-03T08:41:48Z","success":1,"relation":"main_file","creator":"dernst"},{"file_size":93265727,"content_type":"video/mp4","date_updated":"2024-12-11T09:22:13Z","file_name":"2024_ScienceTalk_Clavaud_Video.mp4","checksum":"666c0bd9af8432437554d0c75c540809","access_level":"open_access","file_id":"18646","success":1,"creator":"dernst","relation":"main_file","date_created":"2024-12-11T09:22:13Z"},{"relation":"supplementary_material","creator":"dernst","date_created":"2024-12-11T09:22:19Z","file_size":58282147,"date_updated":"2024-12-11T09:22:19Z","content_type":"video/mp4","access_level":"open_access","checksum":"8fd0d6224d7a0125fcf7d9ca0d80d700","file_name":"2024_ScienceTalk__Clavaud_QA.mp4","file_id":"18647"}],"corr_author":"1","volume":3,"type":"journal_article","citation":{"short":"C.

We have chosen these lower bounds as the proofs are relatively simple, but the techniques can be extended to give lower bounds for many more algorithmic problems. The goal is to present the bounds with minimal notation, making the results accessible to a broad community and stimulating further research in the area.\r\n\r\nSpecifically, we first describe a lower bound on the symbolic complexity of computing strongly connected components, which can be extended to show lower bounds for fundamental model-checking questions in graphs, published in [CDHL16b]. Second we present a conditional lower bound for disjunctive safety problems on graphs from [CDHL18] in the RAM model of computation. This bound can be modified to give conditional lower bounds for disjunctive objectives for reachability, Büchi, coBüchi and Rabin objectives in MDPs. We also present various open questions.","lang":"eng"}],"status":"public","date_created":"2025-07-22T06:19:50Z","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant agreement No. 101019564 “The Design of Modern Fully Dynamic Data Structures (MoDynStruct)” and from the Austrian Science Fund (FWF) project “Fast Algorithms for a Reactive Network Layer (ReactNet)”, P 33775-N, with additional funding from the netidee SCIENCE Stiftung, 2020–2024.","article_processing_charge":"No","publication_identifier":{"eissn":["1611-3349"],"isbn":["9783031223365"],"issn":["0302-9743"],"eisbn":["9783031223372"]},"publication":"Principles of Systems Design","month":"12","scopus_import":"1","_id":"20062","editor":[{"full_name":"Raskin, Jean-François","last_name":"Raskin","first_name":"Jean-François"},{"orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee"},{"last_name":"Doyen","full_name":"Doyen, Laurent","first_name":"Laurent"},{"first_name":"Rupak","last_name":"Majumdar","full_name":"Majumdar, Rupak"}],"series_title":"LNCS","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Henzinger, M.

In this context, synthetic auxin analogs, such as 1-Naphtalene Acetic Acid (1-NAA), are often favored over the endogenous auxin indole-3-acetic acid (IAA), in part due to their higher stability. While such auxin analogs have proven to be instrumental to reveal the various faces of auxin, they display in some cases distinct bioactivities compared to IAA. Here, we focused on the effect of auxin analogs on the accumulation of PIN proteins in Brefeldin A-sensitive endosomal aggregations (BFA bodies), and the correlation with the ability to elicit Ca 2+ responses. For a set of commonly used auxin analogs, we evaluated if auxin-analog induced Ca 2+ signaling inhibits PIN accumulation. Not all auxin analogs elicited a Ca 2+ response, and their differential ability to elicit Ca 2+ responses correlated partially with their ability to inhibit BFA-body formation. However, in tir1/afb and cngc14, 1-NAA-induced Ca 2+ signaling was strongly impaired, yet 1-NAA still could inhibit PIN accumulation in BFA bodies. This demonstrates that TIR1/AFB-CNGC14-dependent Ca 2+ signaling does not inhibit BFA body formation in Arabidopsis roots."}],"status":"public","main_file_link":[{"open_access":"1","url":"https://biblio.ugent.be/publication/8738721"}],"date_created":"2022-02-03T09:19:01Z","acknowledgement":"We thank Joerg Kudla (WWU Munster, Germany), Petra Dietrich (F.A.
