Using atomic force microscopy, we capture the hierarchically organized assemblies of Bin/amphiphysin/Rvs (BAR) proteins on supported lipid membranes. Their structure reveals distinct long linear aggregates of proteins, regularly spaced by up to 300 nm. Employing accurate free-energy calculations from large-scale coarse-grained computer simulations, we found that the membrane mediates the interaction among protein filaments as a combination of short- and long-ranged interactions. The long-ranged component acts at strikingly long distances, giving rise to a variety of micron-sized ordered patterns. This mechanism may contribute to the long-ranged spatiotemporal control of membrane remodeling by proteins in the cell."}],"article_type":"original","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"publisher":"American Chemical Society","main_file_link":[{"url":"https://pubs.acs.org/doi/10.1021/acscentsci.7b00392","open_access":"1"}],"scopus_import":"1","fulldoi":"https://doi.org/10.1021/acscentsci.7b00392","extern":"1","license":"https://creativecommons.org/licenses/by/4.0/","type":"journal_article","page":"1246-1253","volume":3,"publication_status":"published","oa_version":"Published Version","status":"public","citation":{"ieee":"M.

Intriguingly, organelles avoid clashing and entangling with each other in such limited space. Mitochondria form extensive networks constantly remodeled by fission and fusion. Here, we show that mitochondrial fission is triggered by mechanical forces. Mechano-stimulation of mitochondria – via encounter with motile intracellular pathogens, via external pressure applied by an atomic force microscope, or via cell migration across uneven microsurfaces – results in the recruitment of the mitochondrial fission machinery, and subsequent division. We propose that MFF, owing to affinity for narrow mitochondria, acts as a membrane-bound force sensor to recruit the fission machinery to mechanically strained sites. Thus, mitochondria adapt to the environment by sensing and responding to biomechanical cues. Our findings that mechanical triggers can be coupled to biochemical responses in membrane dynamics may explain how organelles orderly cohabit in the crowded cytoplasm.","lang":"eng"}],"article_type":"original","file":[{"date_created":"2021-11-29T09:07:41Z","date_updated":"2021-11-29T09:07:41Z","access_level":"open_access","content_type":"application/pdf","file_id":"10372","success":1,"creator":"cchlebak","file_name":"2017_eLife_Helle.pdf","file_size":6120157,"checksum":"c35f42dcfb007f6d6c761a27e24c26d3","relation":"main_file"}],"doi":"10.7554/elife.30292","title":"Mechanical force induces mitochondrial fission","keyword":["general immunology and microbiology","general biochemistry","genetics and molecular biology","general medicine","general neuroscience"],"language":[{"iso":"eng"}],"_id":"10370","day":"09","pmid":1,"file_date_updated":"2021-11-29T09:07:41Z","intvolume":"         6","publication_identifier":{"issn":["2050-084X"]},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","ddc":["572"],"date_updated":"2021-11-29T09:28:14Z","date_published":"2017-11-09T00:00:00Z","external_id":{"pmid":["29119945"]},"month":"11","has_accepted_license":"1","oa":1,"author":[{"last_name":"Helle","first_name":"Sebastian Carsten Johannes","full_name":"Helle, Sebastian Carsten Johannes"},{"full_name":"Feng, Qian","first_name":"Qian","last_name":"Feng"},{"full_name":"Aebersold, Mathias J","last_name":"Aebersold","first_name":"Mathias J"},{"last_name":"Hirt","first_name":"Luca","full_name":"Hirt, Luca"},{"first_name":"Raphael R","last_name":"Grüter","full_name":"Grüter, Raphael R"},{"full_name":"Vahid, Afshin","last_name":"Vahid","first_name":"Afshin"},{"full_name":"Sirianni, Andrea","last_name":"Sirianni","first_name":"Andrea"},{"full_name":"Mostowy, Serge","first_name":"Serge","last_name":"Mostowy"},{"full_name":"Snedeker, Jess G","last_name":"Snedeker","first_name":"Jess G"},{"first_name":"Anđela","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","last_name":"Šarić","orcid":"0000-0002-7854-2139","full_name":"Šarić, Anđela"},{"full_name":"Idema, Timon","last_name":"Idema","first_name":"Timon"},{"first_name":"Tomaso","last_name":"Zambelli","full_name":"Zambelli, Tomaso"},{"last_name":"Kornmann","first_name":"Benoît","full_name":"Kornmann, Benoît"}],"status":"public","date_created":"2021-11-29T08:51:38Z","citation":{"short":"S.C.J.

The same would be expected to hold for magnetic charges, yet magnetic monopoles have never been observed. It is therefore surprising that the laws of nonequilibrium thermodynamics, combined with Maxwell’s equations, suggest that colloidal particles heated or cooled in certain polar or paramagnetic solvents may behave as if they carry an electric/magnetic charge. Here, we present numerical simulations that show that the field distribution around a pair of such heated/cooled colloidal particles agrees quantitatively with the theoretical predictions for a pair of oppositely charged electric or magnetic monopoles. However, in other respects, the nonequilibrium colloidal particles do not behave as monopoles: They cannot be moved by a homogeneous applied field. The numerical evidence for the monopole-like fields around heated/cooled colloidal particles is crucial because the experimental and numerical determination of forces between such colloidal particles would be complicated by the presence of other effects, such as thermophoresis."}],"publication":"Proceedings of the National Academy of Sciences","article_processing_charge":"No","quality_controlled":"1","type":"journal_article","extern":"1","fulldoi":"https://doi.org/10.1073/pnas.1621494114","main_file_link":[{"url":"https://www.pnas.org/content/114/19/4911","open_access":"1"}],"scopus_import":"1","publisher":"National Academy of Sciences","oa_version":"Published Version","publication_status":"published","volume":114,"page":"4911-4914","year":"2017","date_created":"2021-11-29T09:28:24Z","citation":{"chicago":"Wirnsberger, Peter, Domagoj Fijan, Roger A.

The macroscopic behaviour associated with such processes is remarkably diverse, ranging from simple nucleated growth to highly cooperative processes with a well-defined lagtime. Thus, conventionally, different molecular mechanisms have been used to explain the self-assembly of different proteins. Here we show that this range of behaviour can be quantitatively captured by a single unifying Petri net that describes filamentous growth in terms of aggregate number and aggregate mass concentrations. By considering general features associated with a particular network connectivity, we are able to establish directly the rate-determining steps of the overall aggregation reaction from the system's scaling behaviour. We illustrate the power of this framework on a range of different experimental and simulated aggregating systems.

This interaction works both ways: while proteins influence the membrane shape, the membrane shape affects the interactions between the proteins. To study these membrane-mediated interactions on closed and anisotropically curved membranes, we use colloids adhered to ellipsoidal membrane vesicles as a model system. We find that two particles on a closed system always attract each other, and tend to align with the direction of largest curvature. Multiple particles form arcs, or, at large enough numbers, a complete ring surrounding the vesicle in its equatorial plane. The resulting vesicle shape resembles a snowman. Our results indicate that these physical interactions on membranes with anisotropic shapes can be exploited by cells to drive macromolecules to preferred regions of cellular or intracellular membranes, and utilized to initiate dynamic processes such as cell division. The same principle could be used to find the midplane of an artificial vesicle, as a first step towards dividing it into two equal parts."}],"publication_identifier":{"eissn":["1744-6848"],"issn":["1744-683X"]},"intvolume":"        13","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2021-11-29T10:33:36Z","date_published":"2017-06-15T00:00:00Z","title":"Curvature variation controls particle aggregation on fluid vesicles","arxiv":1,"keyword":["condensed matter physics","general chemistry"],"_id":"10375","language":[{"iso":"eng"}],"day":"15","pmid":1,"issue":"28","status":"public","citation":{"ama":"Vahid A, Šarić A, Idema T.

The input is a graph where the edges are labeled with different types of opening and closing parentheses, and the reachability information is computed via paths whose parentheses are properly matched. We present new results for Dyck reachability problems with applications to alias analysis and data-dependence analysis. Our main contributions, that include improved upper bounds as well as lower bounds that establish optimality guarantees, are as follows: First, we consider Dyck reachability on bidirected graphs, which is the standard way of performing field-sensitive points-to analysis. Given a bidirected graph with n nodes and m edges, we present: (i) an algorithm with worst-case running time O(m + n · α(n)), where α(n) is the inverse Ackermann function, improving the previously known O(n2) time bound; (ii) a matching lower bound that shows that our algorithm is optimal wrt to worst-case complexity; and (iii) an optimal average-case upper bound of O(m) time, improving the previously known O(m · logn) bound. Second, we consider the problem of context-sensitive data-dependence analysis, where the task is to obtain analysis summaries of library code in the presence of callbacks. Our algorithm preprocesses libraries in almost linear time, after which the contribution of the library in the complexity of the client analysis is only linear, and only wrt the number of call sites. Third, we prove that combinatorial algorithms for Dyck reachability on general graphs with truly sub-cubic bounds cannot be obtained without obtaining sub-cubic combinatorial algorithms for Boolean Matrix Multiplication, which is a long-standing open problem. Thus we establish that the existing combinatorial algorithms for Dyck reachability are (conditionally) optimal for general graphs. We also show that the same hardness holds for graphs of constant treewidth. Finally, we provide a prototype implementation of our algorithms for both alias analysis and data-dependence analysis. Our experimental evaluation demonstrates that the new algorithms significantly outperform all existing methods on the two problems, over real-world benchmarks."}],"article_type":"original","quality_controlled":"1","article_processing_charge":"No","doi":"10.1145/3158118","acknowledgement":"The research was partly supported by Austrian Science Fund (FWF) Grant No P23499-N23, FWF NFN Grant No S11407-N23 (RiSE/SHiNE), and ERC Start grant (279307: Graph Games).\r\n","related_material":{"record":[{"id":"5455","relation":"earlier_version","status":"public"}]},"file":[{"relation":"main_file","file_name":"2017_ACMProgLang_Chatterjee.pdf","checksum":"faa3f7b3fe8aab84b50ed805c26a0ee5","file_size":460188,"creator":"cchlebak","success":1,"file_id":"10421","content_type":"application/pdf","access_level":"open_access","date_updated":"2021-12-07T08:06:28Z","date_created":"2021-12-07T08:06:28Z"}]},{"type":"journal_article","fulldoi":"https://doi.org/10.1145/3158121","publisher":"Association for Computing Machinery","scopus_import":"1","main_file_link":[{"url":"https://dl.acm.org/doi/10.1145/3158121","open_access":"1"}],"corr_author":"1","oa_version":"Published Version","publication_status":"published","volume":2,"article_number":"33","doi":"10.1145/3158121","acknowledgement":"McIver and Morgan are grateful to David Basin and the Information Security Group at ETH Zürich for hosting a six-month stay in Switzerland, during part of which this work began.

Like others, we use variant functions (a.k.a. \"super-martingales\") that are real-valued and decrease randomly on each loop iteration; but our key innovation is that the amount as well as the probability of the decrease are parametric.

Towards this, both well-studied cyanobacteria, i.e., Synechocystis sp PCC 6803 and Synechococcus elongatus PCC 7942, have been engineered to produce ethylene by introducing the ethylene-forming enzyme (Efe) from Pseudomonas syringae pv. phaseolicola PK2 (the Kudzu strain), which catalyzes the conversion of the ubiquitous tricarboxylic acid cycle intermediate 2-oxoglutarate into ethylene. Results: This study focuses on Synechocystis sp PCC 6803 and shows stable ethylene production through the integration of a codon-optimized version of the efe gene under control of the Ptrc promoter and the core Shine-Dalgarno sequence (5\\'-AGGAGG-3\\') as the ribosome-binding site (RBS), at the slr0168 neutral site. We have increased ethylene production twofold by RBS screening and further investigated improving ethylene production from a single gene copy of efe, using multiple tandem promoters and by putting our best construct on an RSF1010-based broad-host-self-replicating plasmid, which has a higher copy number than the genome. Moreover, to raise the intracellular amounts of the key Efe substrate, 2-oxoglutarate, from which ethylene is formed, we constructed a glycogen-synthesis knockout mutant (glgC) and introduced the ethylene biosynthetic pathway in it. Under nitrogen limiting conditions, the glycogen knockout strain has increased intracellular 2-oxoglutarate levels; however, surprisingly, ethylene production was lower in this strain than in the wild-type background. Conclusion: Making use of different RBS sequences, production of ethylene ranging over a 20-fold difference has been achieved. However, a further increase of production through multiple tandem promoters and a broad-host plasmid was not achieved speculating that the transcription strength and the gene copy number are not the limiting factors in our system."}],"file":[{"relation":"main_file","file_size":1361313,"creator":"system","file_name":"IST-2017-792-v1+1_s12934-017-0645-5.pdf","file_id":"5240","content_type":"application/pdf","access_level":"open_access","date_created":"2018-12-12T10:16:50Z","date_updated":"2018-12-12T10:16:50Z"}],"doi":"10.1186/s12934-017-0645-5","volume":16,"article_number":"34","oa_version":"Published Version","publication_status":"published","publisher":"BioMed Central","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"scopus_import":"1","type":"journal_article","extern":"1","fulldoi":"https://doi.org/10.1186/s12934-017-0645-5"},{"month":"04","external_id":{"isi":["000399430300022"]},"author":[{"last_name":"Guarina","first_name":"Laura","full_name":"Guarina, Laura"},{"last_name":"Vandael","id":"3AE48E0A-F248-11E8-B48F-1D18A9856A87","first_name":"David H","full_name":"Vandael, David H","orcid":"0000-0001-7577-1676"},{"first_name":"Valentina","last_name":"Carabelli","full_name":"Carabelli, Valentina"},{"full_name":"Carbone, Emilio","last_name":"Carbone","first_name":"Emilio"}],"status":"public","year":"2017","citation":{"ieee":"L.

Recent findings indicate that MCCs possess a variety of spontaneous firing modes that span from the common ‘tonic‐irregular’ to the less frequent ‘burst’ firing. This latter is evident in a small fraction of MCCs but occurs regularly when Nav1.3/1.7 channels are made less available or when the Slo1β2‐subunit responsible for BK channel inactivation is deleted. Burst firing causes large increases of Ca2+‐entry and potentiates CA release by ∼3.5‐fold and thus may be a key mechanism for regulating MCC function. With the aim to uncover a physiological role for burst‐firing we investigated the effects of acidosis on MCC activity. Lowering the extracellular pH (pHo) from 7.4 to 7.0 and 6.6 induces cell depolarizations of 10–15 mV that generate repeated bursts. Bursts at pHo 6.6 lasted ∼330 ms, occurred at 1–2 Hz and caused an ∼7‐fold increase of CA cumulative release. Burst firing originates from the inhibition of the pH‐sensitive TASK‐1/TASK‐3 channels and from a 40% BK channel conductance reduction at pHo 7.0. The same pHo had little or no effect on Nav, Cav, Kv and SK channels that support AP firing in MCCs. Burst firing of pHo 6.6 could be mimicked by mixtures of the TASK‐1 blocker A1899 (300 nm) and BK blocker paxilline (300 nm) and could be prevented by blocking L‐type channels by adding 3 μm nifedipine. Mixtures of the two blockers raised cumulative CA‐secretion even more than low pHo (∼12‐fold), showing that the action of protons on vesicle release is mainly a result of the ionic conductance changes that increase Ca2+‐entry during bursts. Our data provide direct evidence suggesting that MCCs respond to low pHo with sustained depolarization, burst firing and enhanced CA‐secretion, thus mimicking the physiological response of CCs to acute acidosis and hyperkalaemia generated during heavy exercise and muscle fatigue."}],"publication":"Journal of Physiology","doi":"10.1113/JP273735","volume":595,"page":"2587 - 2609 ","oa_version":"None","publication_status":"published","publisher":"Wiley-Blackwell","type":"journal_article","extern":"1","fulldoi":"https://doi.org/10.1113/JP273735"},{"_id":"1063","language":[{"iso":"eng"}],"day":"01","isi":1,"issue":"4","title":"Evolutionary rescue in randomly mating, selfing, and clonal populations","publist_id":"6327","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2026-06-22T14:05:53Z","date_published":"2017-04-01T00:00:00Z","das_tickbox":"1","intvolume":"        71","publication_identifier":{"issn":["0014-3820"]},"oa":1,"author":[{"first_name":"Hildegard","last_name":"Uecker","id":"2DB8F68A-F248-11E8-B48F-1D18A9856A87","full_name":"Uecker, Hildegard","orcid":"0000-0001-9435-2813"}],"external_id":{"biorxivid":["10.1101/081042"],"isi":["000398545200003"]},"month":"04","citation":{"ama":"Uecker H.

How does biparental sexual reproduction influence the chances of population persistence compared to clonal reproduction or selfing? In this article, we set up a one‐locus two‐allele model for adaptation in diploid species, where rescue is contingent on the establishment of the mutant homozygote. Reproduction can occur by random mating, selfing, or clonally. Random mating generates and destroys the rescue mutant; selfing is efficient at generating it but at the same time depletes the heterozygote, which can lead to a low mutant frequency in the standing genetic variation. Due to these (and other) antagonistic effects, we find a nontrivial dependence of population survival on the rate of sex/selfing, which is strongly influenced by the dominance coefficient of the mutation before and after the environmental change. Importantly, since mating with the wild‐type breaks the mutant homozygote up, a slow decay of the wild‐type population size can impede rescue in randomly mating populations.","lang":"eng"}],"quality_controlled":"1","article_processing_charge":"No","doi":"10.1111/evo.13191"},{"doi":"10.1016/j.ipl.2017.02.003","file":[{"date_created":"2018-12-12T10:13:17Z","date_updated":"2019-10-15T07:44:51Z","access_level":"open_access","content_type":"application/pdf","file_id":"4998","file_size":247657,"file_name":"IST-2018-991-v1+2_2018_Chatterjee_Pushdown_PREPRINT.pdf","creator":"system","relation":"main_file"}],"abstract":[{"text":"We consider the problem of reachability in pushdown graphs.

Topological defects of the superconducting order parameter, such as vortices and fluxoid states in multiply connected structures, are often the key ingredients of these phenomena. This dissertation describes a new mode of magnetic force microscopy (Φ0-MFM) for investigating vortex and fluxoid sates in mesoscopic superconducting (SC) structures. The technique relies on the magneto-mechanical coupling of a MFM cantilever to the motion of fluxons. The novelty of the technique is that a magnetic particle attached to the cantilever is used not only to sense the state of a SC structure, but also as a primary source of the inhomogeneous magnetic field which induces that state. Φ0-MFM enables us to map the transitions between tip-induced states during a scan: at the positions of the tip, where the two lowest energy states become degenerate, small oscillations of the tip drive the transitions between these states, which causes a significant shift in the resonant frequency and dissipation of the cantilever. For narrow-wall aluminum rings, the mapped fluxoid transitions form concentric contours on a scan. We show that the changes in the cantilever resonant frequency and dissipation are well-described by a stochastic resonance (SR) of cantilever-driven thermally activated phase slips (TAPS). The SR model allows us to experimentally determine the rate of TAPS and compare it to the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory for TAPS in 1D superconducting structures. Further, we use the SR model to qualitatively study the effects of a locally applied magnetic field on the phase slip rate in rings containing constrictions. The states with multiple vortices or winding numbers could be useful for the development of novel superconducting devices, or the study of vortex interactions and interference effects. Using Φ0-MFM allows us to induce, probe and control fluxoid states in thin wall structures comprised of multiple loops. We show that Φ0-MFM images of the fluxoid transitions allow us to identify the underlying states and to investigate their energetics and dynamics even in complicated structures.","lang":"eng"}],"author":[{"full_name":"Polshyn, Hryhoriy","orcid":"0000-0001-8223-8896","first_name":"Hryhoriy","last_name":"Polshyn","id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48"}],"article_processing_charge":"No","month":"09","citation":{"mla":"Polshyn, Hryhoriy. <i>Magnetic Force Microscopy Studies of Mesoscopic Superconducting Structures</i>.

However, remarkably little is known about how tissues coordinate their movements to shape the embryo. In zebrafish embryogenesis, coordinated tissue movements first become apparent during “doming,” when the blastoderm begins to spread over the yolk sac, a process involving coordinated epithelial surface cell layer expansion and mesenchymal deep cell intercalations. Here, we find that active surface cell expansion represents the key process coordinating tissue movements during doming. By using a combination of theory and experiments, we show that epithelial surface cells not only trigger blastoderm expansion by reducing tissue surface tension, but also drive blastoderm thinning by inducing tissue contraction through radial deep cell intercalations. Thus, coordinated tissue expansion and thinning during doming relies on surface cells simultaneously controlling tissue surface tension and radial tissue contraction."}]},{"acknowledgement":"This research has been supported by the EU project Toposys(FP7-ICT-318493-STREP), by ESF under the ACAT Research Network Programme, by the Russian Government under mega project 11.G34.31.0053, and by the DFG Collaborative Research Center SFB/TRR 109 “Discretization in Geometry and Dynamics”.","doi":"10.1090/tran/6991","article_type":"original","abstract":[{"text":"Given a finite set of points in Rn and a radius parameter, we study the Čech, Delaunay–Čech, Delaunay (or alpha), and Wrap complexes in the light of generalized discrete Morse theory.

These IBD blocks are direct traces of recent coalescence events and, as such, contain ample signal to infer recent demography. Here, we examine sharing of such blocks in two-dimensional populations with local migration. Using a diffusion approximation to trace genetic ancestry, we derive analytical formulae for patterns of isolation by distance of IBD blocks, which can also incorporate recent population density changes. We introduce an inference scheme that uses a composite likelihood approach to fit these formulae. We then extensively evaluate our theory and inference method on a range of scenarios using simulated data. We first validate the diffusion approximation by showing that the theoretical results closely match the simulated block sharing patterns. We then demonstrate that our inference scheme can accurately and robustly infer dispersal rate and effective density, as well as bounds on recent dynamics of population density. To demonstrate an application, we use our estimation scheme to explore the fit of a diffusion model to Eastern European samples in the POPRES data set. We show that ancestry diffusing with a rate of σ ≈ 50–100 km/√gen during the last centuries, combined with accelerating population growth, can explain the observed exponential decay of block sharing with increasing pairwise sample distance.","lang":"eng"}],"project":[{"call_identifier":"FP7","name":"Limits to selection in biology and in evolutionary computation","grant_number":"250152","_id":"25B07788-B435-11E9-9278-68D0E5697425"}],"publication":"Genetics","publication_identifier":{"issn":["0016-6731"]},"intvolume":"       205","date_published":"2017-03-01T00:00:00Z","date_updated":"2026-04-08T14:06:35Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publist_id":"6307","title":"Inferring recent demography from isolation by distance of long shared sequence blocks","issue":"3","isi":1,"day":"01","_id":"1074","language":[{"iso":"eng"}],"status":"public","department":[{"_id":"NiBa"}],"year":"2017","citation":{"ista":"Ringbauer H, Coop G, Barton NH. 2017.

The states with multiple vortices or winding numbers could be useful for the study of vortex interactions and interference effects, the braiding of Majorana bound states by winding vortices, and the development of novel superconducting devices. We demonstrate a methodology based on magnetic force microscopy that allows us to induce, probe and control fluxoid states in thin wall structures comprised of multiple loops. By using micro-magnet as a source of inhomogeneous magnetic field, we can efficiently explore the configuration space of fluxoid states. Scanning over the structure reveals the energy crossing points of the lowest laying fluxoid states. This is due the strong interaction of cantilever with thermally activated fluxoid transitions at points of degeneracy. We show that measured patterns of fluxoid transitions allow to identify the states, investigate their energetics, and manipulate them. Further, we show that the dynamics of driven fluxoid transitions can be described by stochastic resonance model, which provides a unique way of measuring fluxoid transition rate and related energy barrier for chosen transitions even in complicated structures","lang":"eng"}],"publication":"APS March Meeting 2017"},{"date_updated":"2021-01-12T06:48:06Z","user_id":"2EBD1598-F248-11E8-B48F-1D18A9856A87","date_published":"2017-02-01T00:00:00Z","ddc":["001"],"intvolume":"        15","publication_identifier":{"isbn":["978-3643908124"]},"file_date_updated":"2018-12-12T10:08:06Z","day":"01","language":[{"iso":"eng"}],"_id":"1075","publist_id":"6306","title":"An American in Allied-occupied Austria: John Dos Passos Reports on &quot;The Vienna Frontier&quot;","year":"2017","citation":{"mla":"Wenzl, Bernhard. “An American in Allied-Occupied Austria: John Dos Passos Reports on &#38;quot;The Vienna Frontier&#38;quot;” <i>Austria and America: 20th-Century Cross-Cultural Encounters</i>, edited by Joshua Parker and Ralph Poole, vol. 15, LIT Verlag Berlin-Münster-Wien-Zürich-London, 2017, pp. 73–80.","ama":"Wenzl B.

We prove the nonexistence of minimizers for the energy functional when the number of electrons is large and the total nuclear charge is small. This nonexistence result also applies to external potentials decaying faster than the Coulomb potential. In the case of arbitrary nuclear charges, we obtain the nonexistence of stable minimizers and radial minimizers."}],"doi":"10.1007/s11040-017-9238-0","article_number":"6","volume":20,"publication_status":"published","oa_version":"Submitted Version","publisher":"Springer","scopus_import":"1","main_file_link":[{"url":"https://arxiv.org/abs/1603.07368","open_access":"1"}],"fulldoi":"https://doi.org/10.1007/s11040-017-9238-0","type":"journal_article"}]
