In (sequential) token swapping, the goal is to use the shortest possible sequence of swaps, each of which exchanges the tokens at the two endpoints of an edge of the graph. In parallel token swapping, the goal is to use the fewest rounds, each of which consists of one or more swaps on the edges of a matching. We prove that both of these problems remain NP-hard when the graph is restricted to be a tree. These token swapping problems have been studied by disparate groups of researchers in discrete mathematics, theoretical computer science, robot motion planning, game theory, and engineering. Previous work establishes NP-completeness on general graphs (for both problems), constant-factor approximation algorithms, and some poly-time exact algorithms for simple graph classes such as cliques, stars, paths, and cycles. Sequential and parallel token swapping on trees were first studied over thirty years ago (as \"sorting with a transposition tree\") and over twenty-five years ago (as \"routing permutations via matchings\"), yet their complexities were previously unknown. We also show limitations on approximation of sequential token swapping on trees: we identify a broad class of algorithms that encompass all three known polynomial-time algorithms that achieve the best known approximation factor (which is 2) and show that no such algorithm can achieve an approximation factor less than 2."}],"oa":1,"volume":244,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["2103.06707"]}},{"project":[{"_id":"261099A6-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"742985","name":"Tracing Evolution of Auxin Transport and Polarity in Plants"}],"publication_status":"published","editor":[{"first_name":"Ibrokhim Y.","last_name":"Abdurakhmonov","full_name":"Abdurakhmonov, Ibrokhim Y."}],"type":"book_chapter","date_created":"2024-05-29T06:35:13Z","quality_controlled":"1","author":[{"last_name":"Floriach-Clark","first_name":"Jordi","full_name":"Floriach-Clark, Jordi"},{"id":"19BDF720-25A0-11EA-AC6E-928F3DDC885E","first_name":"Han","last_name":"Tang","orcid":"0000-0001-6152-6637","full_name":"Tang, Han"},{"first_name":"Viola","last_name":"Willemsen","full_name":"Willemsen, Viola"}],"publication_identifier":{"isbn":["9781839697500"]},"department":[{"_id":"JiFr"}],"date_updated":"2025-05-14T11:20:40Z","publisher":"IntechOpen","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"publication":"Model Organisms in Plant Genetics","abstract":[{"text":"Mosses are a cosmopolitan group of land plants, sister to vascular plants, with a high potential for molecular and cell biological research. The species Physcomitrium patens has helped gaining better understanding of the biological processes of the plant cell, and it has become a central system to understand water-to-land plant transition through 2D-to-3D growth transition, regulation of asymmetric cell division, shoot apical cell establishment and maintenance, phyllotaxis and regeneration. P. patens was the first fully sequenced moss in 2008, with the latest annotated release in 2018. It has been shown that many gene functions and networks are conserved in mosses when compared to angiosperms. Importantly, this model organism has a simplified and accessible body structure that facilitates close tracking in time and space with the support of live cell imaging set-ups and multiple reporter lines. This has become possible thanks to its fully established molecular toolkit, with highly efficient PEG-assisted, CRISPR/Cas9 and RNAi transformation and silencing protocols, among others. Here we provide examples on how mosses exhibit advantages over vascular plants to study several processes and their future potential to answer some other outstanding questions in plant cell biology.","lang":"eng"}],"oa_version":"Published Version","status":"public","ec_funded":1,"language":[{"iso":"eng"}],"article_processing_charge":"No","day":"23","_id":"17085","citation":{"short":"J.

In this model, an estimator observes n samples of a d-dimensional parameter vector θ∗∈Rd, multiplied by a random sign Si (1≤i≤n), and corrupted by isotropic standard Gaussian noise. The sequence of signs {Si}i∈[n]∈{−1,1}n is drawn from a stationary homogeneous Markov chain with flip probability δ∈[0,1/2]. As δ varies, this model smoothly interpolates two well-studied models: the Gaussian Location Model for which δ=0 and the Gaussian Mixture Model for which δ=1/2. Assuming that the estimator knows δ, we establish a nearly minimax optimal (up to logarithmic factors) estimation error rate, as a function of ∥θ∗∥,δ,d,n. We then provide an upper bound to the case of estimating δ, assuming a (possibly inaccurate) knowledge of θ∗. The bound is proved to be tight when θ∗ is an accurately known constant. These results are then combined to an algorithm which estimates θ∗ with δ unknown a priori, and theoretical guarantees on its error are stated.","lang":"eng"}],"conference":{"start_date":"2022-11-28","end_date":"2022-12-09","name":"NeurIPS: Neural Information Processing Systems","location":"New Orleans, LA, United States"},"file_date_updated":"2024-08-05T09:44:49Z","day":"01","citation":{"apa":"Zhang, Y., & Weinberger, N.

We introduce the Optimal BERT Surgeon (oBERT), an efficient and accurate pruning method based on approximate second-order information, which we show to yield state-of-the-art results in both stages of language tasks: pre-training and fine-tuning. Specifically, oBERT extends existing work on second-order pruning by allowing for pruning weight blocks, and is the first such method that is applicable at BERT scale. Second, we investigate compounding compression approaches to obtain highly compressed but accurate models for deployment on edge devices. These models significantly push boundaries of the current state-of-the-art sparse BERT models with respect to all metrics: model size, inference speed and task accuracy. For example, relative to the dense BERT-base, we obtain 10x model size compression with < 1% accuracy drop, 10x CPU-inference speedup with < 2% accuracy drop, and 29x CPU-inference speedup with < 7.5% accuracy drop.

In the same step, the chosen node picks a random neighbor, and the two nodes balance their loads by averaging them. We are interested in the expected gap between the minimum and maximum loads at nodes as the process progresses, and its dependence on n and on the graph structure. Variants of the above graphical balanced allocation process have been studied previously by Peres, Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and Sun, 2015]. These authors left as open the question of characterizing the gap in the case of cycle graphs in the dynamic case, where weights are created during the algorithm’s execution. For this case, the only known upper bound is of 𝒪(n log n), following from a majorization argument due to [Peres et al., 2015], which analyzes a related graphical allocation process. In this paper, we provide an upper bound of 𝒪 (√n log n) on the expected gap of the above process for cycles of length n. We introduce a new potential analysis technique, which enables us to bound the difference in load between k-hop neighbors on the cycle, for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds the maximum value of the gap by bounding its value across all possible subsets of a certain structure, and recursively bounding the gaps within each subset. We provide analytical and experimental evidence that our upper bound on the gap is tight up to a logarithmic factor.

A natural (and efficient) way to approximate an isomanifold is to consider its Piecewise-Linear (PL) approximation based on a triangulation T of the ambient space Rd. In this paper, we give conditions under which the PL-approximation of an isomanifold is topologically equivalent to the isomanifold. The conditions are easy to satisfy in the sense that they can always be met by taking a sufficiently\r\nfine triangulation T . This contrasts with previous results on the triangulation of manifolds where, in arbitrary dimensions, delicate perturbations are needed to guarantee topological correctness, which leads to strong limitations in practice. We further give a bound on the Fréchet distance between the original isomanifold and its PL-approximation. Finally we show analogous results for the PL-approximation of an isomanifold with boundary.","lang":"eng"}],"oa":1,"volume":22,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"isi":["000673039600001"]},"date_updated":"2025-04-22T13:45:18Z","publication_identifier":{"eissn":["1615-3383"]},"date_created":"2021-07-14T06:44:53Z","author":[{"last_name":"Boissonnat","first_name":"Jean-Daniel","full_name":"Boissonnat, Jean-Daniel"},{"last_name":"Wintraecken","first_name":"Mathijs","id":"307CFBC8-F248-11E8-B48F-1D18A9856A87","full_name":"Wintraecken, Mathijs","orcid":"0000-0002-7472-2220"}],"project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"}],"scopus_import":"1","month":"01","title":"The topological correctness of PL approximations of isomanifolds","date_published":"2022-01-01T00:00:00Z","year":"2022","_id":"9649","intvolume":" 22","article_processing_charge":"Yes (via OA deal)","article_type":"original","language":[{"iso":"eng"}],"status":"public","ec_funded":1,"ddc":["516"],"publication":"Foundations of Computational Mathematics ","related_material":{"record":[{"relation":"earlier_version","id":"7952","status":"public"}]},"has_accepted_license":"1","publisher":"Springer Nature","corr_author":"1","file":[{"creator":"mwintrae","access_level":"open_access","checksum":"f1d372ec3c08ec22e84f8e93e1126b8c","date_updated":"2021-07-14T06:44:36Z","file_name":"Boissonnat-Wintraecken2021_Article_TheTopologicalCorrectnessOfPLA.pdf","date_created":"2021-07-14T06:44:36Z","relation":"main_file","file_size":1455699,"content_type":"application/pdf","file_id":"9650"}],"department":[{"_id":"HeEd"}],"quality_controlled":"1","publication_status":"published","type":"journal_article","doi":"10.1007/s10208-021-09520-0","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"acknowledgement":"First and foremost, we acknowledge Siargey Kachanovich for discussions.

When assessing the similarity between data points, one can build various distance measures using subsets of these features. Using the fewest features but still retaining sufficient information about the system is crucial in many statistical learning approaches, particularly when data are sparse. We introduce a statistical test that can assess the relative information retained when using two different distance measures, and determine if they are equivalent, independent, or if one is more informative than the other. This in turn allows finding the most informative distance measure out of a pool of candidates. The approach is applied to find the most relevant policy variables for controlling the Covid-19 epidemic and to find compact yet informative representations of atomic structures, but its potential applications are wide ranging in many branches of science."}],"oa_version":"Published Version","arxiv":1,"pmid":1,"external_id":{"arxiv":["2104.15079"],"pmid":["36713323"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"volume":1,"language":[{"iso":"eng"}],"article_processing_charge":"Yes","article_type":"original","status":"public","date_published":"2022-05-01T00:00:00Z","scopus_import":"1","month":"05","title":"Ranking the information content of distance measures","intvolume":" 1","_id":"9695","year":"2022","department":[{"_id":"BiCh"}],"file":[{"file_id":"17080","success":1,"file_size":2005167,"content_type":"application/pdf","relation":"main_file","date_created":"2024-05-29T06:21:33Z","file_name":"2022_PNASNexus_Glielmo.pdf","date_updated":"2024-05-29T06:21:33Z","access_level":"open_access","creator":"dernst","checksum":"f6552854d760eb574ce97abce2c8ef89"}],"publication_status":"published","type":"journal_article","quality_controlled":"1","ddc":["000"],"publication":"PNAS Nexus","publisher":"Oxford University Press","has_accepted_license":"1","file_date_updated":"2024-05-29T06:21:33Z","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","article_number":"pgac039","doi":"10.1093/pnasnexus/pgac039","issue":"2","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"acknowledgement":"A.G., C.Z., and A.L. gratefully acknowledge support from the European Union’s Horizon 2020 research and innovation program (grant number 824143, MaX ’Materials design at the eXascale’ Centre of Excellence).

Immunological challenge causes LNs to increase more than tenfold in size within a few days. Here, we characterized the biomechanics of LN swelling on the cellular and organ scale. We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion. Thus, different fibroblast populations mechanically control LN swelling in a multitier fashion."}],"volume":23,"oa":1,"external_id":{"pmid":["35817845"],"isi":["000822975900002"]},"pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2022-07-25T07:11:32Z","page":"1246-1255","acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"PreCl"},{"_id":"LifeSc"}],"doi":"10.1038/s41590-022-01257-4","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"acknowledgement":"This research was supported by the Scientific Service Units of IST Austria through resources provided by the Imaging and Optics, Electron Microscopy, Preclinical and Life Science Facilities.

Here, we explored the development of the neurotransmitter identity of neurons of the avian nucleus isthmi parvocellularis (Ipc), whose axon terminals are retinotopically arranged in the optic tectum (TeO) and exert a focal gating effect upon the ascending transmission of retinal inputs. Although cholinergic and glutamatergic markers are both found in Ipc neurons and terminals of adult pigeons and chicks, the mRNA expression of the vesicular acetylcholine transporter, VAChT, is weak or absent. To explore how the Ipc neurotransmitter identity is established during ontogeny, we analyzed the expression of mRNAs coding for cholinergic (ChAT, VAChT, and CHT) and glutamatergic (VGluT2 and VGluT3) markers in chick embryos at different developmental stages. We found that between E12 and E18, Ipc neurons expressed all cholinergic mRNAs and also VGluT2 mRNA; however, from E16 through posthatch stages, VAChT mRNA expression was specifically diminished. Our ex vivo deposits of tracer crystals and intracellular filling experiments revealed that Ipc axons exhibit a mature paintbrush morphology late in development, experiencing marked morphological transformations during the period of presumptive dual vesicular transmitter release. Additionally, although ChAT protein immunoassays increasingly label the growing Ipc axon, this labeling was consistently restricted to sparse portions of the terminal branches. Combined, these results suggest that the synthesis of glutamate and acetylcholine, and their vesicular release, is complexly linked to the developmental processes of branching, growing and remodeling of these unique axons."}],"oa_version":"None","pmid":1,"external_id":{"pmid":["34363623"],"isi":["000686420000001"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","volume":530},{"date_published":"2022-03-01T00:00:00Z","scopus_import":"1","month":"03","title":"Resurgence analysis of quantum invariants of Seifert fibered homology spheres","intvolume":" 105","_id":"9977","year":"2022","language":[{"iso":"eng"}],"article_processing_charge":"Yes (via OA deal)","article_type":"original","status":"public","ec_funded":1,"abstract":[{"lang":"eng","text":"For a Seifert fibered homology sphere X we show that the q-series invariant Zˆ0(X; q) introduced by Gukov-Pei-Putrov-Vafa, is a resummation of the Ohtsuki series Z0(X).

In high activity regimes, such as epileptic episodes, this process is thought to rely on the glutamate-glutamine cycle between neurons and astrocytes. However the presence of an astroglial glutamine supply, as well as its functional relevance in vivo in the healthy brain remain controversial, partly due to a lack of tools that can directly examine glutamine transfer. Here, we generated a fluorescent probe that tracks glutamine in live cells, which provides direct visual evidence of an activity-dependent glutamine supply from astroglial networks to presynaptic structures under physiological conditions. This mobilization is mediated by connexin43, an astroglial protein with both gap-junction and hemichannel functions, and is essential for synaptic transmission and object recognition memory. Our findings uncover an indispensable recruitment of astroglial glutamine in physiological synaptic activity and memory via an unconventional pathway, thus providing an astrocyte basis for cognitive processes."}],"status":"public","article_type":"original","article_processing_charge":"No","language":[{"iso":"eng"}],"year":"2022","_id":"10764","intvolume":" 13","title":"Physiological synaptic activity and recognition memory require astroglial glutamine","month":"02","scopus_import":"1","date_published":"2022-02-08T00:00:00Z"},{"date_updated":"2026-04-02T12:14:43Z","publication_identifier":{"eissn":["2041-1723"]},"date_created":"2022-02-20T23:01:30Z","author":[{"full_name":"Herguedas, Beatriz","first_name":"Beatriz","last_name":"Herguedas"},{"full_name":"Kohegyi, Bianka K.","last_name":"Kohegyi","first_name":"Bianka K."},{"full_name":"Dohrke, Jan Niklas","last_name":"Dohrke","first_name":"Jan Niklas"},{"id":"63836096-4690-11EA-BD4E-32803DDC885E","last_name":"Watson","first_name":"Jake","full_name":"Watson, Jake","orcid":"0000-0002-8698-3823"},{"first_name":"Danyang","last_name":"Zhang","full_name":"Zhang, Danyang"},{"full_name":"Ho, Hinze","first_name":"Hinze","last_name":"Ho"},{"full_name":"Shaikh, Saher A.","first_name":"Saher A.","last_name":"Shaikh"},{"full_name":"Lape, Remigijus","first_name":"Remigijus","last_name":"Lape"},{"full_name":"Krieger, James M.","first_name":"James M.","last_name":"Krieger"},{"full_name":"Greger, Ingo H.","last_name":"Greger","first_name":"Ingo H."}],"oa_version":"Published Version","abstract":[{"text":"AMPA-type glutamate receptors (AMPARs) mediate rapid signal transmission at excitatory\r\nsynapses in the brain.

Gating kinetics shape synaptic transmission\r\nand are strongly modulated by transmembrane AMPAR regulatory proteins (TARPs)\r\nthrough currently incompletely resolved mechanisms. Here, electron cryo-microscopy\r\nstructures of the GluA1/2 TARP-γ8 complex, in both open and desensitized states\r\n(at 3.5 Å), reveal state-selective engagement of the LBDs by the large TARP-γ8 loop (‘β1’),\r\nelucidating how this TARP stabilizes specific gating states. We further show how TARPs alter\r\nchannel rectification, by interacting with the pore helix of the selectivity filter. Lastly, we\r\nreveal that the Q/R-editing site couples the channel constriction at the filter entrance to the\r\ngate, and forms the major cation binding site in the conduction path.

Nos enfocamos en fermiones de Dirac masivos con potencial químico en 1+1 dimensiones espacio-temporales. Usando la entropía de entrelazamiento en un intervalo, construimos la función c entrópica que es finita. Esta función c no es monótona, e incorpora el entrelazamiento de largo alcance proveniente de la superficie de Fermi. Motivados por trabajos previos de modelos en la red, calculamos numéricamente las entropías de Renyi y encontramos oscilaciones de Friedel. Seguidamente, analizamos la información mutua como una medida de correlación entre diferentes regiones. Usando una expansión de distancia grande desarrollada por Cardy, argumentamos que la información mutua detecta las correlaciones inducidas por la superficie de Fermi todavía al orden dominante en la expansión. Finalmente, analizamos la entropía relativa y sus generalizaciones de Renyi para distinguir estados con diferente carga. Encontramos que estados en diferentes sectores de superselección dan origen a un comportamiento super-extensivo en la entropía relativa.","lang":"eng"}],"oa_version":"Published Version","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","volume":32,"oa":1,"OA_type":"gold","publication_identifier":{"eissn":["1850-1168"]},"date_updated":"2026-04-02T12:30:12Z","date_created":"2022-02-20T23:01:32Z","author":[{"first_name":"L.","last_name":"Daguerre","full_name":"Daguerre, L."},{"first_name":"G.","last_name":"Torroba","full_name":"Torroba, G."},{"orcid":"0000-0002-5383-2869","full_name":"Medina Ramos, Raimel A","first_name":"Raimel A","last_name":"Medina Ramos","id":"CE680B90-D85A-11E9-B684-C920E6697425"},{"full_name":"Solís, M.","last_name":"Solís","first_name":"M."}],"date_published":"2022-01-13T00:00:00Z","month":"01","scopus_import":"1","title":"Non relativistic quantum field theory: Dynamics and irreversibility","intvolume":" 32","year":"2022","_id":"10769","language":[{"iso":"spa"}],"article_processing_charge":"No","article_type":"original","status":"public","DOAJ_listed":"1","ddc":["530"],"publication":"Anales de la Asociacion Fisica Argentina","publisher":"Asociación Física Argentina","has_accepted_license":"1","OA_place":"publisher","department":[{"_id":"MaSe"}],"file":[{"file_id":"10782","success":1,"content_type":"application/pdf","file_size":4505751,"date_created":"2022-02-21T09:32:44Z","relation":"main_file","creator":"dernst","access_level":"open_access","checksum":"ca66a3017205677c5b4d22b3bb74fb0b","date_updated":"2022-02-21T09:32:44Z","file_name":"2022_AnalesAFA_Daguerre.pdf"}],"publication_status":"published","type":"journal_article","quality_controlled":"1","doi":"10.31527/analesafa.2021.32.4.93","issue":"4","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"acknowledgement":"Se agradece a Horacio Casini por distintas discusiones y comentarios a lo largo del trabajo.
