DAT surface availability is dynamically regulated by endocytic trafficking, and direct protein kinase C (PKC) activation acutely diminishes DAT surface expression by accelerating DAT internalization. Previous cell line studies demonstrated that PKC-stimulated DAT endocytosis requires both Ack1 inactivation, which releases a DAT-specific endocytic brake, and the neuronal GTPase, Rit2, which binds DAT. However, it is unknown whether Rit2 is required for PKC-stimulated DAT endocytosis in DAergic terminals or whether there are region- and/or sex-dependent differences in PKC-stimulated DAT trafficking. Moreover, the mechanisms by which Rit2 controls PKC-stimulated DAT endocytosis are unknown. Here, we directly examined these important questions. Ex vivo studies revealed that PKC activation acutely decreased DAT surface expression selectively in ventral, but not dorsal, striatum. AAV-mediated, conditional Rit2 knockdown in DAergic neurons impacted baseline DAT surface:intracellular distribution in DAergic terminals from female ventral, but not dorsal, striatum. Further, Rit2 was required for PKC-stimulated DAT internalization in both male and female ventral striatum. FRET and surface pulldown studies in cell lines revealed that PKC activation drives DAT-Rit2 surface dissociation and that the DAT N terminus is required for both PKC-mediated DAT-Rit2 dissociation and DAT internalization. Finally, we found that Rit2 and Ack1 independently converge on DAT to facilitate PKC-stimulated DAT endocytosis. Together, our data provide greater insight into mechanisms that mediate PKC-regulated DAT internalization and reveal unexpected region-specific differences in PKC-stimulated DAT trafficking in bona fide DAergic terminals.

At the calyx of Held in brainstem slices from rats of either sex, isoflurane at clinical doses attenuated EPSCs by decreasing the release probability and the number of readily releasable vesicles. In presynaptic recordings of Ca2+ currents and exocytic capacitance changes, isoflurane attenuated exocytosis by inhibiting Ca2+ currents evoked by a short presynaptic depolarization, whereas it inhibited exocytosis evoked by a prolonged depolarization via directly blocking exocytic machinery downstream of Ca2+ influx. Since the length of presynaptic depolarization can simulate the frequency of synaptic inputs, isoflurane anesthesia is likely mediated by distinct dual mechanisms, depending on input frequencies. In simultaneous presynaptic and postsynaptic action potential recordings, isoflurane impaired the fidelity of repetitive spike transmission, more strongly at higher frequencies. Furthermore, in the cerebrum of adult mice, isoflurane inhibited monosynaptic corticocortical spike transmission, preferentially at a higher frequency. We conclude that dual presynaptic mechanisms operate for the anesthetic action of isoflurane, of which direct inhibition of exocytic machinery plays a low-pass filtering role in spike transmission at central excitatory synapses.","lang":"eng"}],"publication":"Journal of Neuroscience","issue":"21","oa_version":"Published Version","has_accepted_license":"1","scopus_import":"1","publication_status":"published","department":[{"_id":"RySh"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"file":[{"file_name":"2020_JourNeuroscience_Wang.pdf","date_created":"2020-06-02T09:12:16Z","relation":"main_file","date_updated":"2020-07-14T12:48:05Z","access_level":"open_access","checksum":"6571607ea9036154b67cc78e848a7f7d","creator":"dernst","file_id":"7912","file_size":3817360,"content_type":"application/pdf"}],"title":"Frequency-dependent block of excitatory neurotransmission by isoflurane via dual presynaptic mechanisms","license":"https://creativecommons.org/licenses/by/4.0/","author":[{"first_name":"Han Ying","last_name":"Wang","full_name":"Wang, Han Ying"},{"orcid":"0000-0002-6170-2546","full_name":"Eguchi, Kohgaku","id":"2B7846DC-F248-11E8-B48F-1D18A9856A87","last_name":"Eguchi","first_name":"Kohgaku"},{"first_name":"Takayuki","full_name":"Yamashita, Takayuki","last_name":"Yamashita"},{"first_name":"Tomoyuki","last_name":"Takahashi","full_name":"Takahashi, Tomoyuki"}],"external_id":{"pmid":["32327530"],"isi":["000535694700004"]}},{"author":[{"full_name":"Mistakidis, S.

The presented numerical simulations are based upon the variational multilayer multiconfiguration time-dependent Hartree method for bosons. To analyze and quantify induced impurity-impurity correlations, we employ an effective two-body Hamiltonian with a contact interaction.

The majority of high-temperature experiments performed thus far, however, have been unable to discern whether the antinodal states are rendered unobservable due to their damping or whether they vanish due to their gapping7,8,9,10,11,12,13,14,15,16,17,18. Here, we distinguish between these two scenarios by using quantum oscillations to examine whether the small Fermi surface pocket, found to occupy only 2% of the Brillouin zone in the underdoped cuprates19,20,21,22,23,24, exists in isolation against a majority of completely gapped density of states spanning the antinodes, or whether it is thermodynamically coupled to a background of ungapped antinodal states. We find that quantum oscillations associated with the small Fermi surface pocket exhibit a signature sawtooth waveform characteristic of an isolated two-dimensional Fermi surface pocket25,26,27,28,29,30,31,32. This finding reveals that the antinodal states are destroyed by a hard gap that extends over the majority of the Brillouin zone, placing strong constraints on a drastic underlying origin of quasiparticle disappearance over almost the entire Brillouin zone in the pseudogap regime7,8,9,10,11,12,13,14,15,16,17,18.","lang":"eng"}],"day":"01","publication_status":"published","scopus_import":"1","related_material":{"record":[{"status":"public","relation":"research_data","id":"9708"}]}},{"oa":1,"month":"07","article_processing_charge":"No","volume":71,"citation":{"ama":"Maghiaoui A, Bouguyon E, Cuesta C, et al.

Besides its role as a nutrient, nitrate has been shown to act as a signal molecule for plant growth, development and stress responses. In Arabidopsis, the NRT1.1 nitrate transceptor represses lateral root (LR) development at low nitrate availability by promoting auxin basipetal transport out of the LR primordia (LRPs). In addition, our present study shows that NRT1.1 acts as a negative regulator of the TAR2 auxin biosynthetic gene expression in the root stele. This is expected to repress local auxin biosynthesis and thus to reduce acropetal auxin supply to the LRPs. Moreover, NRT1.1 also negatively affects expression of the LAX3 auxin influx carrier, thus preventing cell wall remodeling required for overlying tissues separation during LRP emergence. Both NRT1.1-mediated repression of TAR2 and LAX3 are suppressed at high nitrate availability, resulting in the nitrate induction of TAR2 and LAX3 expression that is required for optimal stimulation of LR development by nitrate. Altogether, our results indicate that the NRT1.1 transceptor coordinately controls several crucial auxin-associated processes required for LRP development, and as a consequence that NRT1.1 plays a much more integrated role than previously anticipated in regulating the nitrate response of root system architecture."}],"day":"25","oa_version":"Submitted Version","publication_status":"published","scopus_import":"1"},{"date_updated":"2023-09-05T12:17:46Z","status":"public","publisher":"American Society for Biochemistry and Molecular Biology","type":"journal_article","intvolume":"        19","acknowledgement":"We thank Maria Njo, Sarah De Cokere, Marieke Mispelaere and Darren Wells, for practical assistance, Daniël Van Damme for assistance with image analysis, Marnik Vuylsteke for advice on statistics, Catherine Perrot-Rechenmann for useful discussions, Steffen Lau for critical reading oft he manuscript, and Philip Benfey, Gerd Jürgens, Philippe Nacry, Frederik Börnke, and Frans Tax for sharing materials.","doi":"10.1074/mcp.ra119.001826","_id":"7949","page":"1248-1262","pmid":1,"year":"2020","isi":1,"article_type":"original","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","date_created":"2020-06-08T10:10:53Z","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1535-9484"]},"quality_controlled":"1","file_date_updated":"2021-05-05T10:10:14Z","date_published":"2020-08-01T00:00:00Z","oa":1,"month":"08","article_processing_charge":"No","volume":19,"citation":{"short":"S.

Our (phospho)proteome-wide analyses of C-terminally encoded peptide 5 (CEP5)-mediated changes revealed an impact on abiotic stress-related processes. Drought has a dramatic impact on plant growth, development and reproduction, and the plant hormone auxin plays a role in drought responses. Our genetic, physiological, biochemical and pharmacological results demonstrated that CEP5-mediated signaling is relevant for osmotic and drought stress tolerance in Arabidopsis, and that CEP5 specifically counteracts auxin effects. Specifically, we found that CEP5 signaling stabilizes AUX/IAA transcriptional repressors, suggesting the existence of a novel peptide-dependent control mechanism that tunes auxin signaling. These observations align with the recently described role of AUX/IAAs in stress tolerance and provide a novel role for CEP5 in osmotic and drought stress tolerance."}],"external_id":{"isi":["000561114000001"],"pmid":["32404488"]},"author":[{"full_name":"Smith, S","last_name":"Smith","first_name":"S"},{"first_name":"S","full_name":"Zhu, S","last_name":"Zhu"},{"first_name":"L","last_name":"Joos","full_name":"Joos, L"},{"first_name":"I","last_name":"Roberts","full_name":"Roberts, I"},{"last_name":"Nikonorova","first_name":"N","full_name":"Nikonorova, N"},{"full_name":"Vu, LD","last_name":"Vu","first_name":"LD"},{"full_name":"Stes, E","last_name":"Stes","first_name":"E"},{"first_name":"H","full_name":"Cho, H","last_name":"Cho"},{"full_name":"Larrieu, A","first_name":"A","last_name":"Larrieu"},{"full_name":"Xuan, W","last_name":"Xuan","first_name":"W"},{"last_name":"Goodall","full_name":"Goodall, B","first_name":"B"},{"full_name":"van de Cotte, B","last_name":"van de Cotte","first_name":"B"},{"first_name":"JM","full_name":"Waite, JM","last_name":"Waite"},{"last_name":"Rigal","full_name":"Rigal, A","first_name":"A"},{"full_name":"R Harborough, SR","last_name":"R Harborough","first_name":"SR"},{"first_name":"G","last_name":"Persiau","full_name":"Persiau, G"},{"first_name":"S","last_name":"Vanneste","full_name":"Vanneste, S"},{"full_name":"Kirschner, GK","last_name":"Kirschner","first_name":"GK"},{"last_name":"Vandermarliere","first_name":"E","full_name":"Vandermarliere, E"},{"full_name":"Martens, L","first_name":"L","last_name":"Martens"},{"last_name":"Stahl","full_name":"Stahl, Y","first_name":"Y"},{"first_name":"D","last_name":"Audenaert","full_name":"Audenaert, D"},{"id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jiří","full_name":"Friml, Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596"},{"last_name":"Felix","first_name":"G","full_name":"Felix, G"},{"full_name":"Simon, R","first_name":"R","last_name":"Simon"},{"first_name":"M","full_name":"Bennett, M","last_name":"Bennett"},{"last_name":"Bishopp","full_name":"Bishopp, A","first_name":"A"},{"full_name":"De Jaeger, G","first_name":"G","last_name":"De Jaeger"},{"full_name":"Ljung, K","first_name":"K","last_name":"Ljung"},{"first_name":"S","full_name":"Kepinski, S","last_name":"Kepinski"},{"last_name":"Robert","full_name":"Robert, S","first_name":"S"},{"last_name":"Nemhauser","first_name":"J","full_name":"Nemhauser, J"},{"first_name":"I","full_name":"Hwang, I","last_name":"Hwang"},{"last_name":"Gevaert","first_name":"K","full_name":"Gevaert, K"},{"full_name":"Beeckman, T","first_name":"T","last_name":"Beeckman"},{"first_name":"I","last_name":"De Smet","full_name":"De Smet, I"}],"title":"The CEP5 peptide promotes abiotic stress tolerance, as revealed by quantitative proteomics, and attenuates the AUX/IAA equilibrium in Arabidopsis","file":[{"checksum":"3f3f37b4a1ba2cfd270fc7733dd89680","file_id":"9373","creator":"kschuh","access_level":"open_access","date_updated":"2021-05-05T10:10:14Z","relation":"main_file","date_created":"2021-05-05T10:10:14Z","success":1,"file_name":"2020_MCP_Smith.pdf","content_type":"application/pdf","file_size":1632311}],"department":[{"_id":"JiFr"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"}},{"alternative_title":["LIPIcs"],"article_number":"20:1-20:18","related_material":{"record":[{"id":"9649","status":"public","relation":"later_version"}]},"has_accepted_license":"1","publication_status":"published","corr_author":"1","scopus_import":"1","publication":"36th International Symposium on Computational Geometry","project":[{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"abstract":[{"text":"Isomanifolds are the generalization of isosurfaces to arbitrary dimension and codimension, i.e. manifolds defined as the zero set of some multivariate vector-valued smooth function f: ℝ^d → ℝ^(d-n).

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 fine 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.

From that perspective, chiral molecules acting as efficient spin selectors pose a puzzle that attracted a lot of attention in recent years. Here, we revisit the physical origins of chiral-induced spin selectivity (CISS) and propose a simple analytic minimal model to describe it. The model treats a chiral molecule as an anisotropic wire with molecular dipole moments aligned arbitrarily with respect to the wire’s axes and is therefore quite general. Importantly, it shows that the helical structure of the molecule is not necessary to observe CISS and other chiral nonhelical molecules can also be considered as potential candidates for the CISS effect. We also show that the suggested simple model captures the main characteristics of CISS observed in the experiment, without the need for additional constraints employed in the previous studies. The results pave the way for understanding other related physical phenomena where the CISS effect plays an essential role."}],"issue":"21","publication":"The Journal of Physical Chemistry C","oa_version":"Published Version","ec_funded":1,"has_accepted_license":"1","scopus_import":"1","publication_status":"published","corr_author":"1"},{"day":"15","abstract":[{"lang":"eng","text":"Multilayer graphene lattices allow for an additional tunability of the band structure by the strong perpendicular electric field. In particular, the emergence of the new multiple Dirac points in ABA stacked trilayer graphene subject to strong transverse electric fields was proposed theoretically and confirmed experimentally. These new Dirac points dubbed “gullies” emerge from the interplay between strong electric field and trigonal warping. In this work, we first characterize the properties of new emergent Dirac points and show that the electric field can be used to tune the distance between gullies in the momentum space. We demonstrate that the band structure has multiple Lifshitz transitions and higher-order singularity of “monkey saddle” type. Following the characterization of the band structure, we consider the spectrum of Landau levels and structure of their wave functions. In the limit of strong electric fields when gullies are well separated in momentum space, they give rise to triply degenerate Landau levels. In the second part of this work, we investigate how degeneracy between three gully Landau levels is lifted in the presence of interactions. Within the Hartree-Fock approximation we show that the symmetry breaking state interpolates between the fully gully polarized state that breaks C3  symmetry at high displacement field and the gully symmetric state when the electric field is decreased. The discontinuous transition between these two states is driven by enhanced intergully tunneling and exchange. We conclude by outlining specific experimental predictions for the existence of such a symmetry-breaking state."}],"publication":"Physical Review B","issue":"24","oa_version":"Preprint","article_number":"245411","scopus_import":"1","publication_status":"published","department":[{"_id":"MaSe"}],"main_file_link":[{"url":"https://arxiv.org/abs/2002.05739","open_access":"1"}],"title":"Gully quantum Hall ferromagnetism in biased trilayer graphene","author":[{"id":"47C23AC6-02D0-11E9-BD0E-99399A5D3DEB","full_name":"Rao, Peng","first_name":"Peng","last_name":"Rao","orcid":"0000-0003-1250-0021"},{"orcid":"0000-0002-2399-5827","first_name":"Maksym","full_name":"Serbyn, Maksym","last_name":"Serbyn","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"}],"external_id":{"isi":["000538715500010"],"arxiv":["2002.05739"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","isi":1,"year":"2020","_id":"7971","doi":"10.1103/physrevb.101.245411","intvolume":"       101","publisher":"American Physical Society","status":"public","type":"journal_article","date_updated":"2025-06-04T07:45:18Z","citation":{"ista":"Rao P, Serbyn M. 2020.

Batteries are vital to this endeavor, whether used in electric vehicles, to store renewable electricity, or in aviation. Present lithium-ion technologies are preparing the public for this inevitable change, but their maximum theoretical specific capacity presents a limitation. Their high cost is another concern for commercial viability. Metal–air batteries have the highest theoretical energy density of all possible secondary battery technologies and could yield step changes in energy storage, if their practical difficulties could be overcome. The scope of this review is to provide an objective, comprehensive, and authoritative assessment of the intensive work invested in nonaqueous rechargeable metal–air batteries over the past few years, which identified the key problems and guides directions to solve them. We focus primarily on the challenges and outlook for Li–O2 cells but include Na–O2, K–O2, and Mg–O2 cells for comparison. Our review highlights the interdisciplinary nature of this field that involves a combination of materials chemistry, electrochemistry, computation, microscopy, spectroscopy, and surface science. The mechanisms of O2 reduction and evolution are considered in the light of recent findings, along with developments in positive and negative electrodes, electrolytes, electrocatalysis on surfaces and in solution, and the degradative effect of singlet oxygen, which is typically formed in Li–O2 cells.","lang":"eng"}],"ddc":["540"],"day":"05","oa_version":"Submitted Version","has_accepted_license":"1","publication_status":"published","scopus_import":"1","file":[{"file_size":8525678,"content_type":"application/pdf","file_name":"ChemRev_final.pdf","date_created":"2020-06-29T16:36:01Z","date_updated":"2020-07-14T12:48:06Z","relation":"main_file","access_level":"open_access","creator":"sfreunbe","file_id":"8060","checksum":"1a683353d46c5841c8bb2ee0a56ac7be"}],"department":[{"_id":"StFr"}],"title":"Lithium-oxygen batteries and related systems: Potential, status, and future","author":[{"full_name":"Kwak, WJ","last_name":"Kwak","first_name":"WJ"},{"full_name":"Sharon, D","last_name":"Sharon","first_name":"D"},{"full_name":"Xia, C","last_name":"Xia","first_name":"C"},{"first_name":"H","last_name":"Kim","full_name":"Kim, H"},{"first_name":"LR","last_name":"Johnson","full_name":"Johnson, LR"},{"first_name":"PG","full_name":"Bruce, PG","last_name":"Bruce"},{"last_name":"Nazar","first_name":"LF","full_name":"Nazar, LF"},{"full_name":"Sun, YK","first_name":"YK","last_name":"Sun"},{"full_name":"Frimer, AA","first_name":"AA","last_name":"Frimer"},{"last_name":"Noked","full_name":"Noked, M","first_name":"M"},{"id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","first_name":"Stefan Alexander","full_name":"Freunberger, Stefan Alexander","last_name":"Freunberger","orcid":"0000-0003-2902-5319"},{"full_name":"Aurbach, D","first_name":"D","last_name":"Aurbach"}],"external_id":{"pmid":["32134255"],"isi":["000555413600008"]}},{"date_updated":"2025-07-10T11:54:54Z","type":"conference","status":"public","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","intvolume":"       164","doi":"10.4230/LIPIcs.SoCG.2020.61","_id":"7989","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"date_created":"2020-06-22T09:14:18Z","conference":{"start_date":"2020-06-22","location":"Zürich, Switzerland","end_date":"2020-06-26","name":"SoCG: Symposium on Computational Geometry"},"language":[{"iso":"eng"}],"quality_controlled":"1","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771436"]},"file_date_updated":"2020-07-14T12:48:06Z","date_published":"2020-06-01T00:00:00Z","oa":1,"article_processing_charge":"No","volume":164,"month":"06","citation":{"short":"Z.

Combined with a recent result of Holmsen and Lee, it gives fractional Helly theorem, and consequently the existence of weak ε-nets as well as a (p,q)-theorem. More precisely: Let X be either ℝ^d, smooth real d-manifold, or a finite d-dimensional simplicial complex. Then if F is a finite, intersection-closed family of sets in X such that the ith reduced Betti number (with ℤ₂ coefficients) of any set in F is at most b for every non-negative integer i less or equal to k, then the Radon number of F is bounded in terms of b and X. Here k is the smallest integer larger or equal to d/2 - 1 if X = ℝ^d; k=d-1 if X is a smooth real d-manifold and not a surface, k=0 if X is a surface and k=d if X is a d-dimensional simplicial complex. Using the recent result of the author and Kalai, we manage to prove the following optimal bound on fractional Helly number for families of open sets in a surface: Let F be a finite family of open sets in a surface S such that the intersection of any subfamily of F is either empty, or path-connected. Then the fractional Helly number of F is at most three.

A partial triangulation on P is a full triangulation of some subset P' of P containing all extreme points in P. A bistellar flip on a partial triangulation either flips an edge, removes a non-extreme point of degree 3, or adds a point in P ⧵ P' as vertex of degree 3. The bistellar flip graph has all partial triangulations as vertices, and a pair of partial triangulations is adjacent if they can be obtained from one another by a bistellar flip. The goal of this paper is to investigate the structure of this graph, with emphasis on its connectivity. For sets P of n points in general position, we show that the bistellar flip graph is (n-3)-connected, thereby answering, for sets in general position, an open questions raised in a book (by De Loera, Rambau, and Santos) and a survey (by Lee and Santos) on triangulations. This matches the situation for the subfamily of regular triangulations (i.e., partial triangulations obtained by lifting the points and projecting the lower convex hull), where (n-3)-connectivity has been known since the late 1980s through the secondary polytope (Gelfand, Kapranov, Zelevinsky) and Balinski’s Theorem. Our methods also yield the following results (see the full version [Wagner and Welzl, 2020]): (i) The bistellar flip graph can be covered by graphs of polytopes of dimension n-3 (products of secondary polytopes). (ii) A partial triangulation is regular, if it has distance n-3 in the Hasse diagram of the partial order of partial subdivisions from the trivial subdivision. (iii) All partial triangulations are regular iff the trivial subdivision has height n-3 in the partial order of partial subdivisions. (iv) There are arbitrarily large sets P with non-regular partial triangulations, while every proper subset has only regular triangulations, i.e., there are no small certificates for the existence of non-regular partial triangulations (answering a question by F. Santos in the unexpected direction)."}],"ddc":["510"],"corr_author":"1","publication_status":"published","scopus_import":"1","article_number":"67:1 - 67:16","alternative_title":["LIPIcs"],"has_accepted_license":"1","related_material":{"record":[{"id":"12129","status":"public","relation":"later_version"}]}},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"7991","year":"2020","doi":"10.4230/LIPIcs.SoCG.2020.12","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","type":"conference","status":"public","date_updated":"2025-07-10T11:54:56Z","intvolume":"       164","volume":164,"article_processing_charge":"No","month":"06","oa":1,"citation":{"mla":"Avvakumov, Sergey, and Gabriel Nivasch. “Homotopic Curve Shortening and the Affine Curve-Shortening Flow.” <i>36th International Symposium on Computational Geometry</i>, vol. 164, 12:1-12:15, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2020, doi:<a href=\"https://doi.org/10.4230/LIPIcs.SoCG.2020.12\">10.4230/LIPIcs.SoCG.2020.12</a>.","ieee":"S.

Our process, which we call homotopic curve shortening (HCS), starts with a closed curve (which might self-intersect) in the presence of a set P⊂ ℝ² of point obstacles, and evolves in discrete steps, where each step consists of (1) taking shortcuts around the obstacles, and (2) reducing the curve to its shortest homotopic equivalent. We find experimentally that, if the initial curve is held fixed and P is chosen to be either a very fine regular grid or a uniformly random point set, then HCS behaves at the limit like the affine curve-shortening flow (ACSF). This connection between HCS and ACSF generalizes the link between \"grid peeling\" and the ACSF observed by Eppstein et al. (2017), which applied only to convex curves, and which was studied only for regular grids. We prove that HCS satisfies some properties analogous to those of ACSF: HCS is invariant under affine transformations, preserves convexity, and does not increase the total absolute curvature. Furthermore, the number of self-intersections of a curve, or intersections between two curves (appropriately defined), does not increase. Finally, if the initial curve is simple, then the number of inflection points (appropriately defined) does not increase."}],"ddc":["510"],"oa_version":"Published Version","alternative_title":["LIPIcs"],"article_number":"12:1 - 12:15","has_accepted_license":"1","publication_status":"published","scopus_import":"1","file":[{"file_name":"2020_LIPIcsSoCG_Avvakumov.pdf","checksum":"6872df6549142f709fb6354a1b2f2c06","creator":"dernst","file_id":"8007","date_created":"2020-06-23T11:13:49Z","access_level":"open_access","date_updated":"2020-07-14T12:48:06Z","relation":"main_file","content_type":"application/pdf","file_size":575896}],"department":[{"_id":"UlWa"}],"tmp":{"short":"CC BY (3.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/3.0/legalcode","name":"Creative Commons Attribution 3.0 Unported (CC BY 3.0)"},"title":"Homotopic curve shortening and the affine curve-shortening flow","author":[{"id":"3827DAC8-F248-11E8-B48F-1D18A9856A87","last_name":"Avvakumov","first_name":"Sergey","full_name":"Avvakumov, Sergey","orcid":"0000-0002-7840-5062"},{"last_name":"Nivasch","full_name":"Nivasch, Gabriel","first_name":"Gabriel"}],"license":"https://creativecommons.org/licenses/by/3.0/","external_id":{"arxiv":["1909.00263"]}},{"conference":{"start_date":"2020-06-22","location":"Zürich, Switzerland","name":"SoCG: Symposium on Computational Geometry","end_date":"2020-06-26"},"arxiv":1,"date_created":"2020-06-22T09:14:20Z","quality_controlled":"1","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771436"]},"language":[{"iso":"eng"}],"date_published":"2020-06-01T00:00:00Z","file_date_updated":"2020-07-14T12:48:06Z","citation":{"short":"Z.

Given a point p in the interior of K, a hyperplane h passing through p is called barycentric if p is the barycenter of K ∩ h. In 1961, Grünbaum raised the question whether, for every K, there exists an interior point p through which there are at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly resolved affirmatively by showing that this is the case if p=p₀ is the point of maximal depth in K. However, while working on a related question, we noticed that one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample; this re-opens Grünbaum’s question. It follows from known results that for n ≥ 2, there are always at least three distinct barycentric cuts through the point p₀ ∈ K of maximal depth. Using tools related to Morse theory we are able to improve this bound: four distinct barycentric cuts through p₀ are guaranteed if n ≥ 3.","lang":"eng"}],"ddc":["510"],"publication":"36th International Symposium on Computational Geometry"},{"date_updated":"2025-07-10T11:54:58Z","status":"public","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","type":"conference","intvolume":"       164","doi":"10.4230/LIPIcs.SoCG.2020.9","_id":"7994","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"date_created":"2020-06-22T09:14:21Z","conference":{"end_date":"2020-06-26","name":"SoCG: Symposium on Computational Geometry","location":"Zürich, Switzerland","start_date":"2020-06-22"},"language":[{"iso":"eng"}],"quality_controlled":"1","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771436"]},"file_date_updated":"2020-07-14T12:48:06Z","date_published":"2020-06-01T00:00:00Z","oa":1,"article_processing_charge":"No","month":"06","volume":164,"citation":{"ama":"Arroyo Guevara AM, Bensmail J, Bruce Richter R.

One example where multiple barrier effects are coupled consists of a single trait that is under divergent natural selection and also mediates assortative mating. Such multiple‐effect traits can strongly reduce gene flow. However, there are few cases where patterns of assortative mating have been described quantitatively and their impact on gene flow has been determined. Two ecotypes of the coastal marine snail, Littorina saxatilis , occur in North Atlantic rocky‐shore habitats dominated by either crab predation or wave action. There is evidence for divergent natural selection acting on size, and size‐assortative mating has previously been documented. Here, we analyze the mating pattern in L. saxatilis with respect to size in intensively sampled transects across boundaries between the habitats. We show that the mating pattern is mostly conserved between ecotypes and that it generates both assortment and directional sexual selection for small male size. Using simulations, we show that the mating pattern can contribute to reproductive isolation between ecotypes but the barrier to gene flow is likely strengthened more by sexual selection than by assortment."}],"day":"01","project":[{"grant_number":"797747","name":"Theoretical and empirical approaches to understanding Parallel Adaptation","call_identifier":"H2020","_id":"265B41B8-B435-11E9-9278-68D0E5697425"}],"publication":"Evolution","issue":"7","oa_version":"Published Version","ec_funded":1,"author":[{"first_name":"Samuel","last_name":"Perini","full_name":"Perini, Samuel"},{"last_name":"Rafajlović","full_name":"Rafajlović, Marina","first_name":"Marina"},{"orcid":"0000-0003-1050-4969","first_name":"Anja M","id":"3C147470-F248-11E8-B48F-1D18A9856A87","last_name":"Westram","full_name":"Westram, Anja M"},{"full_name":"Johannesson, Kerstin","first_name":"Kerstin","last_name":"Johannesson"},{"last_name":"Butlin","full_name":"Butlin, Roger K.","first_name":"Roger K."}],"external_id":{"isi":["000539780800001"]},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"department":[{"_id":"NiBa"}],"file":[{"file_size":1080810,"content_type":"application/pdf","access_level":"open_access","date_updated":"2020-11-25T10:49:48Z","relation":"main_file","date_created":"2020-11-25T10:49:48Z","creator":"dernst","file_id":"8808","checksum":"56235bf1e2a9e25f96196bb13b6b754d","file_name":"2020_Evolution_Perini.pdf","success":1}],"title":"Assortative mating, sexual selection, and their consequences for gene flow in Littorina"}]
