The simplest, and very common symmetry of this type is the equivariance of the defining equations under the orthogonal group O(2). We formulate a novel symmetry reduction scheme for such systems by combining the method of slices with invariant polynomial methods, and show how it works by applying it to the Kuramoto–Sivashinsky system in one spatial dimension. As an example, we track a relative periodic orbit through a sequence of bifurcations to the onset of chaos. Within the symmetry-reduced state space we are able to compute and visualize the unstable manifolds of relative periodic orbits, their torus bifurcations, a transition to chaos via torus breakdown, and heteroclinic connections between various relative periodic orbits. It would be very hard to carry through such analysis in the full state space, without a symmetry reduction such as the one we present here.","lang":"eng"}],"oa_version":"Submitted Version","day":"01","date_published":"2017-05-01T00:00:00Z","isi":1,"file":[{"file_id":"5319","content_type":"application/pdf","date_created":"2018-12-12T10:18:01Z","file_size":2820207,"date_updated":"2020-07-14T12:44:39Z","file_name":"IST-2017-782-v1+1_BudCvi15.pdf","checksum":"3e971d09eb167761aa0888ed415b0056","creator":"system","access_level":"open_access","relation":"main_file"}],"volume":167,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2017","file_date_updated":"2020-07-14T12:44:39Z","publication_status":"published","has_accepted_license":"1","oa":1,"intvolume":"       167","issue":"3-4","publication":"Journal of Statistical Physics","author":[{"full_name":"Budanur, Nazmi B","last_name":"Budanur","orcid":"0000-0003-0423-5010","id":"3EA1010E-F248-11E8-B48F-1D18A9856A87","first_name":"Nazmi B"},{"full_name":"Cvitanović, Predrag","last_name":"Cvitanović","first_name":"Predrag"}],"department":[{"_id":"BjHo"}],"publisher":"Springer","_id":"1211","language":[{"iso":"eng"}],"scopus_import":"1","publist_id":"6136","article_processing_charge":"No","date_created":"2018-12-11T11:50:44Z"},{"ec_funded":1,"publication_status":"published","volume":137,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2017","publication":"Cytokinesis","intvolume":"       137","project":[{"name":"Synthesis of bacterial cell wall","_id":"2596EAB6-B435-11E9-9278-68D0E5697425","grant_number":"ALTF 2015-1163"},{"_id":"25681D80-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"291734","name":"International IST Postdoc Fellowship Programme"}],"department":[{"_id":"MaLo"}],"author":[{"first_name":"Natalia","id":"38661662-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3086-9124","last_name":"Baranova","full_name":"Baranova, Natalia"},{"id":"462D4284-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7309-9724","first_name":"Martin","full_name":"Loose, Martin","last_name":"Loose"}],"scopus_import":"1","article_processing_charge":"No","publist_id":"6134","date_created":"2018-12-11T11:50:45Z","publisher":"Academic Press","_id":"1213","language":[{"iso":"eng"}],"acknowledgement":"Natalia Baranova is supported by an EMBO Long-Term Fellowship (EMBO ALTF 1163-2015) and Martin Loose by an ERC Starting Grant (ERCStG-2015-SelfOrganiCell).","alternative_title":["Methods in Cell Biology"],"date_updated":"2025-07-10T11:50:24Z","quality_controlled":"1","status":"public","external_id":{"isi":["000403542900022"]},"page":"355 - 370","title":"Single-molecule measurements to study polymerization dynamics of FtsZ-FtsA copolymers","doi":"10.1016/bs.mcb.2016.03.036","type":"book_chapter","editor":[{"first_name":"Arnaud ","last_name":"Echard","full_name":"Echard, Arnaud "}],"publication_identifier":{"issn":["0091-679X"]},"citation":{"mla":"Baranova, Natalia S., and Martin Loose. “Single-Molecule Measurements to Study Polymerization Dynamics of FtsZ-FtsA Copolymers.” <i>Cytokinesis</i>, edited by Arnaud  Echard, vol. 137, Academic Press, 2017, pp. 355–70, doi:<a href=\"https://doi.org/10.1016/bs.mcb.2016.03.036\">10.1016/bs.mcb.2016.03.036</a>.","ieee":"N.

Its primary component is FtsZ, a tubulin-like GTPase, that like its eukaryotic relative forms protein filaments in the presence of GTP. Since the discovery of the Z-ring 25 years ago, various models for the role of FtsZ have been suggested. However, important information about the architecture and dynamics of FtsZ filaments during cytokinesis is still missing. One reason for this lack of knowledge has been the small size of bacteria, which has made it difficult to resolve the orientation and dynamics of individual FtsZ filaments in the Z-ring. While superresolution microscopy experiments have helped to gain more information about the organization of the Z-ring in the dividing cell, they were not yet able to elucidate a mechanism of how FtsZ filaments reorganize during assembly and disassembly of the Z-ring. In this chapter, we explain how to use an in vitro reconstitution approach to investigate the self-organization of FtsZ filaments recruited to a biomimetic lipid bilayer by its membrane anchor FtsA. We show how to perform single-molecule experiments to study the behavior of individual FtsZ monomers during the constant reorganization of the FtsZ-FtsA filament network. We describe how to analyze the dynamics of single molecules and explain why this information can help to shed light onto possible mechanism of Z-ring constriction. We believe that similar experimental approaches will be useful to study the mechanism of membrane-based polymerization of other cytoskeletal systems, not only from prokaryotic but also eukaryotic origin."}],"oa_version":"None","acknowledged_ssus":[{"_id":"Bio"}],"day":"01"},{"author":[{"full_name":"Killip, Rowan","last_name":"Killip","first_name":"Rowan"},{"first_name":"Satoshi","last_name":"Masaki","full_name":"Masaki, Satoshi"},{"full_name":"Murphy, Jason","last_name":"Murphy","first_name":"Jason"},{"full_name":"Visan, Monica","last_name":"Visan","id":"056daca0-b8d1-11f0-964f-f91054abf8ca","first_name":"Monica"}],"article_number":"38","language":[{"iso":"eng"}],"_id":"22025","publisher":"Springer Nature","das_tickbox":"1","date_created":"2026-06-19T07:32:33Z","article_processing_charge":"No","scopus_import":"1","year":"2017","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":24,"oa":1,"OA_type":"green","publication_status":"published","intvolume":"        24","publication":"Nonlinear Differential Equations and Applications NoDEA","issue":"4","extern":"1","month":"06","citation":{"ista":"Killip R, Masaki S, Murphy J, Vişan M. 2017.

The current best known approach due to Huber [9] uses O(qlnn⋅[lnq+lnlnn+ε−2]) oracle calls on average where ε is the desired accuracy of approximation and H(⋅) is assumed to lie in {0}∪[1,n]. We improve the complexity to O(qlnn⋅ε−2) oracle calls.

However, whether developmental methylation reprogramming during the sporophytic life cycle of flowering plants regulates genes is presently unknown.

Loss of sexual-lineage-specific RdDM causes mis-splicing of the MPS1 gene (also known as PRD2), thereby disrupting meiosis.

These rapidly evolving techniques allow for the generation of neuronal sub-populations, and have sparked interest not only in monogenetic neuro-psychiatric diseases, but also in poly-genetic and poly-aetiological disorders such as schizophrenia (SCZ) and bipolar disorder (BPD). This review provides a summary of 19 publications on reprogrammed adult somatic cells derived from patients with SCZ, and five publications using this technique in patients with BPD. As both disorders are complex and heterogeneous, there is a plurality of hypotheses to be tested in vitro. In SCZ, data on alterations of dopaminergic transmission in vitro are sparse, despite the great explanatory power of the so-called DA hypothesis of SCZ. Some findings correspond to perturbations of cell energy metabolism, and observations in reprogrammed cells suggest neuro-developmental alterations. Some studies also report on the efficacy of medicinal compounds to revert alterations observed in cellular models. However, due to the paucity of replication studies, no comprehensive conclusions can be drawn from studies using reprogrammed cells at the present time. In the future, findings from cell culture methods need to be integrated with clinical, epidemiological, pharmacological and imaging data in order to generate a more comprehensive picture of SCZ and BPD."}],"oa_version":"Published Version","day":"01","type":"journal_article","doi":"10.1111/ejn.13418","citation":{"ieee":"U.

Here we introduce a new phenomenon that occurs with vaporizable soft solids - the elastic Leidenfrost effect. By dropping hydrogel spheres onto hot surfaces we find that, rather than hovering, they energetically bounce several times their diameter for minutes at a time. With high-speed video during a single impact, we uncover high-frequency microscopic gap dynamics at the sphere/substrate interface. We show how these otherwise-hidden agitations constitute work cycles that harvest mechanical energy from the vapour and sustain the bouncing.

Starting with the seminal work of Onak and Rubinfeld [STOC 2010], this problem has received significant attention in recent years. Very recently, extending the framework of Baswana, Gupta and Sen [FOCS 2011], Solomon [FOCS 2016] gave a randomized 2-approximation dynamic algorithm for this problem that has amortized update time of O(1) with high probability. We consider the natural open question of derandomizing this result. We present a new deterministic fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover and maximum fractional matching, with an amortized update time of O(1). Previously, the best deterministic algorithm for this problem was due to Bhattacharya, Henzinger and Italiano [SODA 2015]; it had an approximation ratio of (2+ϵ) and an amortized update time of O(logn/ϵ2). Our result can be generalized to give a fully dynamic O(f3)-approximation algorithm with O(f2) amortized update time for the hypergraph vertex cover and fractional matching problems, where every hyperedge has at most f vertices.","lang":"eng"}],"oa_version":"Preprint","main_file_link":[{"url":"https://arxiv.org/abs/1611.00198","open_access":"1"}],"date_published":"2017-05-24T00:00:00Z","date_updated":"2024-11-06T12:03:44Z","alternative_title":["LNCS"],"title":"Deterministic fully dynamic approximate vertex cover and fractional matching in O(1) amortized update time","page":"86-98","external_id":{"arxiv":["1611.00198"]},"status":"public","quality_controlled":"1","author":[{"first_name":"Sayan","last_name":"Bhattacharya","full_name":"Bhattacharya, Sayan"},{"first_name":"Deeparnab","full_name":"Chakrabarty, Deeparnab","last_name":"Chakrabarty"},{"full_name":"Henzinger, Monika H","last_name":"Henzinger","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","orcid":"0000-0002-5008-6530"}],"_id":"12571","language":[{"iso":"eng"}],"publisher":"Springer Nature","date_created":"2023-02-20T07:52:31Z","article_processing_charge":"No","scopus_import":"1","year":"2017","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":10328,"oa":1,"publication_status":"published","intvolume":"     10328","conference":{"name":"IPCO: Integer Programming and Combinatorial Optimization","location":"Waterloo, ON, Canada","end_date":"2017-06-28","start_date":"2017-06-26"},"publication":"19th International Conference on Integer Programming and Combinatorial Optimization"},{"date_published":"2017-12-01T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.1017/jog.2017.65","open_access":"1"}],"day":"01","oa_version":"Published Version","abstract":[{"text":"The spatio-temporal distribution of air temperature over mountain glaciers can demonstrate complex patterns, yet it is often represented simplistically using linear vertical temperature gradients (VTGs) extrapolated from off-glacier locations. We analyse a network of centreline and lateral air temperature observations at Tsanteleina Glacier, Italy, during summer 2015. On average, VTGs are steep (&lt;−0.0065 °C m<jats:sup>−1</jats:sup>), but they are shallow under warm ambient conditions when the correlation between air temperature and elevation becomes weaker. Published along-flowline temperature distribution methods explain centreline observations well, including warming on the lower glacier tongue, but cannot estimate lateral temperature variability. Application of temperature distribution methods improves simulation of melt rates (RMSE) in an energy-balance model by up to 36% compared to the environmental lapse rate extrapolated from an off-glacier station. However, results suggest that model parameters are not easily transferable to glaciers with a small fetch without recalibration. Such methods have potential to improve estimates of temperature across a glacier, but their parameter transferability should be further linked to the glacier and atmospheric characteristics. Furthermore, ‘cold spots’, which can be &gt;2°C cooler than expected for their elevation, whose occurrence is not predicted by the temperature distribution models, are identified at one-quarter of the measurement sites.","lang":"eng"}],"type":"journal_article","doi":"10.1017/jog.2017.65","extern":"1","citation":{"apa":"SHAW, T.

Here, we simulate the distributed energy and mass balance of Juncal Norte Glacier (33°S) during a 2-month summer period. Forcing fields of near-surface air temperature and wind speed are generated using two methods accounting for the main physical processes that shape their spatial variations. Simulated meteorological variables and ablation agree well with observations on the glacier tongue and reveal complex patterns of energy and mass fluxes. Ablation decreases from 70 mm w.e. d<jats:sup>−1</jats:sup> at the low-albedo glacier terminus (~3000 m), where almost 100% of total ablation corresponds to melt, to &lt;5 mm w.e. d<jats:sup>−1</jats:sup> at wind-exposed, strong-radiated sites above 5500 m, where surface sublimation represents &gt;75% of total ablation. Our simulations provide the first glacier-scale estimates of ablation components on a glacier in the study region and better reproduce the observed and expected spatial variations of melt and surface sublimation, in comparison with more simple assumptions, such as linear gradients and uniform wind speeds.","lang":"eng"}],"oa_version":"Published Version","doi":"10.1017/jog.2017.46","type":"journal_article","extern":"1","citation":{"ieee":"A.

Supraglacial ponds represent sinks within the discontinuous supraglacial drainage system, and occasionally drain englacially. To assess pond dynamics, we made pond water level measurements on Lirung Glacier, Nepal, during May and October of 2013 and 2014. Simultaneously, aerial, satellite, and terrestrial orthoimages and digital elevation models were obtained, providing snapshots of the ponds and their surroundings. We performed a DEM-based analysis of the glacier's closed surface catchments to identify surface drainage pathways and englacial drainage points, and compared this to field observations of surface and near-surface water flow. The total ponded area was higher in the pre-monsoon than post-monsoon, with individual ponds filling and draining seasonally associated with the surface exposure of englacial conduit segments. We recorded four pond drainage events, all of which occurred gradually (duration of weeks), observed diurnal fluctuations indicative of varying water supply and outflow discharge, and we documented instances of interaction between distant ponds. The DEM drainage analysis identified numerous sinks >3 m in depth across the glacier surface, few of which exhibited ponds (23%), while the field survey highlighted instances of surface water only explicable via englacial routes. Taken together, our observations provide evidence for widespread supraglacial-englacial connectivity of meltwater drainage paths. Results suggest that successive englacial conduit collapse events, themselves likely driven by supraglacial pond drainage, cause the glacier surface drainage system to evolve into a configuration following relict englacial conduit systems. Within this system, ponds form in depressions of reduced drainage efficiency and link the supraglacial and englacial drainage networks."}],"day":"21","publication_status":"published","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":5,"year":"2017","publication":"Frontiers in Earth Science","intvolume":"         5","keyword":["General Earth and Planetary Sciences"],"article_number":"69","author":[{"full_name":"Miles, Evan S.","last_name":"Miles","first_name":"Evan S."},{"first_name":"Jakob","full_name":"Steiner, Jakob","last_name":"Steiner"},{"first_name":"Ian","full_name":"Willis, Ian","last_name":"Willis"},{"full_name":"Buri, Pascal","last_name":"Buri","first_name":"Pascal"},{"first_name":"Walter W.","last_name":"Immerzeel","full_name":"Immerzeel, Walter W."},{"full_name":"Chesnokova, Anna","last_name":"Chesnokova","first_name":"Anna"},{"first_name":"Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","full_name":"Pellicciotti, Francesca","last_name":"Pellicciotti"}],"article_processing_charge":"No","scopus_import":"1","date_created":"2023-02-20T08:14:04Z","publisher":"Frontiers Media","language":[{"iso":"eng"}],"_id":"12610"}]
