We used the ant Cardiocondyla obscurior as a model system to study adaptive adjustment of male mating tactics. This species shows a male diphenism of wingless fighter males and peaceful winged males. Whereas the wingless males stay and exclusively mate in the maternal colony, the mating behaviour of winged males is plastic. They copulate with female sexuals in their natal nests early in life but later disperse in search for sexuals outside. In this study, we observed the nest-leaving behaviour of winged males under different conditions and found that they adaptively adjust the timing of their dispersal to the availability of mating partners, as well as the presence, and even the type of competitors in their natal nests. In colonies with virgin female queens winged males stayed longest when they were the only male in the nest. They left earlier when mating partners were not available or when other males were present. In the presence of wingless, locally mating fighter males, winged males dispersed earlier than in the presence of docile, winged competitors. This suggests that C. obscurior males are capable of estimating their local breeding chances and adaptively adjust their dispersal behaviour in both an opportunistic and a risk-sensitive way, thus showing hitherto unknown behavioural plasticity in social insect males.","lang":"eng"}],"date_created":"2018-12-11T12:03:07Z","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2025-09-30T08:40:50Z","citation":{"mla":"Cremer, Sylvia, et al. “Competition and Opportunity Shape the Reproductive Tactics of Males in the Ant Cardiocondyla Obscurior.” <i>PLoS One</i>, vol. 6, no. 3, e17323, Public Library of Science, 2011, doi:<a href=\"https://doi.org/10.1371/journal.pone.0017323\">10.1371/journal.pone.0017323</a>.","ieee":"S.

The simplest models of gradient formation rely on constant protein synthesis and diffusion from anteriorly localized source mRNA, coupled with uniform protein degradation. However, currently such models cannot account for all known gradient characteristics. Recent work has proposed that bicoid mRNA spatial distribution is sufficient to produce the observed protein gradient, minimizing the role of protein transport. Here, we adapt a novel method of fluorescent in situ hybridization to quantify the global spatio-temporal dynamics of bicoid mRNA particles. We determine that &gt;90% of all bicoid mRNA is continuously present within the anterior 20% of the embryo. bicoid mRNA distribution along the body axis remains nearly unchanged despite dynamic mRNA translocation from the embryo core to the cortex. To evaluate the impact of mRNA distribution on protein gradient dynamics, we provide detailed quantitative measurements of nuclear Bicoid levels during the formation of the protein gradient. We find that gradient establishment begins 45 minutes after fertilization and that the gradient requires about 50 minutes to reach peak levels. In numerical simulations of gradient formation, we find that incorporating the actual bicoid mRNA distribution yields a closer prediction of the observed protein dynamics compared to modeling protein production from a point source at the anterior pole. We conclude that the spatial distribution of bicoid mRNA contributes to, but cannot account for, protein gradient formation, and therefore that protein movement, either active or passive, is required for gradient formation."}],"title":"The formation of the Bicoid morphogen gradient requires protein movement from anteriorly localized source","year":"2011","type":"journal_article","article_number":"e1000596","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Public Library of Science","oa_version":"None","doi":"10.1371/journal.pbio.1000596"},{"department":[{"_id":"HaJa"}],"ddc":["570","571"],"language":[{"iso":"eng"}],"volume":2,"date_published":"2011-03-08T00:00:00Z","publication":"Nature Communications","external_id":{"isi":["000289982600022"]},"has_accepted_license":"1","intvolume":"         2","day":"08","article_processing_charge":"No","date_created":"2018-12-11T12:03:09Z","abstract":[{"lang":"eng","text":"Glutamate is the major excitatory neurotransmitter in the mammalian central nervous system and gates non-selective cation channels.

The S-peptide from ribonuclease S forms its α-helical structure only upon binding to the folded S-protein. We characterized the transition state for this binding-induced folding reaction at high resolution by determining the effect of site-specific backbone thioxylation and side-chain modifications on the kinetics and thermodynamics of the reaction, which allows us to monitor formation of backbone hydrogen bonds and side-chain interactions in the transition state. The experiments reveal that α-helical structure in the S-peptide is absent in the transition state of binding. Recognition between the unfolded S-peptide and the S-protein is mediated by loosely packed hydrophobic side-chain interactions in two well defined regions on the S-peptide. Close packing and helix formation occurs rapidly after binding. Introducing hydrophobic residues at positions outside the recognition region can drastically slow down association.","lang":"eng"}],"date_updated":"2023-11-07T11:50:29Z","citation":{"mla":"Bachmann, Annett, et al. “Mapping Backbone and Side-Chain Interactions in the Transition State of a Coupled Protein Folding and Binding Reaction.” <i>PNAS</i>, vol. 108, no. 10, Proceedings of the National Academy of Sciences, 2011, pp. 3952–57, doi:<a href=\"https://doi.org/10.1073/pnas.1012668108\">10.1073/pnas.1012668108</a>.","ieee":"A.

This conjecture generalizes the Cauchy identity for Macdonald polynomials and is a common generalization of two formulas that we prove in this paper. The first is a formula for the E-polynomial of these character varieties which we obtain using the character table of GLn(Fq). We use this formula to compute the Euler characteristic of character varieties. The second formula gives the Poincaré polynomial of certain associated quiver varieties which we obtain using the character table of gln(Fq). In the last main result we prove that the Poincaré polynomials of the quiver varieties equal certain multiplicities in the tensor product of irreducible characters of GLn(Fq). As a consequence we find a curious connection between Kac-Moody algebras associated with comet-shaped, and typically wild, quivers and the representation theory of GLn(Fq).","lang":"eng"}],"page":"323 - 400","extern":1,"acknowledgement":"Hausel’s work was supported by National Science Foundation grants DMS-0305505 and DMS-0604775, by an Alfred Sloan Fellowship, and by a Royal Society University Research Fellowship.

We start with molecules terminated with trimethyltin end groups that cleave off in situ, resulting in formation of a direct covalent σ bond between the carbon backbone and the gold metal electrodes. The molecular carbon backbone used in this study consist of a conjugated π system that has one terminal methylene group on each end, which bonds to the electrodes, achieving large electronic coupling of the electrodes to the π system. The junctions formed with the prototypical example of 1,4-dimethylenebenzene show a conductance approaching one conductance quantum (G0 = 2e2/h). Junctions formed with methylene-terminated oligophenyls with two to four phenyl units show a 100-fold increase in conductance compared with junctions formed with amine-linked oligophenyls. The conduction mechanism for these longer oligophenyls is tunneling, as they exhibit an exponential dependence of conductance on oligomer length. In addition, density functional theory based calculations for the Au–xylylene–Au junction show near-resonant transmission, with a crossover to tunneling for the longer oligomers.","lang":"eng"}],"date_created":"2024-09-09T12:33:46Z","type":"journal_article","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"scopus_import":"1","oa_version":"Preprint","pmid":1},{"article_processing_charge":"No","date_updated":"2025-01-03T09:36:40Z","citation":{"short":"M.

Through combination of HAS and STM data, we determine that the molecules are bound on step edges with an adsorption energy of about 1.2 eV, which is about 0.2 eV stronger than the adsorption energy we measure on flat surface. Preferential bonding to the under-coordinated Au atoms on step edges suggests that the molecules bind to Au through the nitrogen lone pair.

Herein we report scanning tunneling microscope based break junction measurements of cobalt chalcogenide clusters with Te, Se and S to probe the conductance properties. Our measured conductance trends show that the Co–Te based clusters have the highest conductance while the Co-S clusters the lowest. These trends are in very good agreement with cyclic voltammetry measurements of the first oxidation potentials and with density functional theory calculations of their HOMO–LUMO gaps."}],"article_processing_charge":"No","pmid":1,"publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"scopus_import":"1","oa_version":"None","date_published":"2011-05-03T00:00:00Z","volume":133,"language":[{"iso":"eng"}],"day":"03","intvolume":"       133","external_id":{"pmid":["21539375"]},"OA_type":"closed access","publication":"Journal of the American Chemical Society","year":"2011","title":"Conductance of single cobalt chalcogenide cluster junctions","page":"8455-8457","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Chemical Society","doi":"10.1021/ja201334s","author":[{"full_name":"Boardman, Brycelyn M.","first_name":"Brycelyn M.","last_name":"Boardman"},{"full_name":"Widawsky, Jonathan R.","first_name":"Jonathan R.","last_name":"Widawsky"},{"full_name":"Park, Young S.","first_name":"Young S.","last_name":"Park"},{"first_name":"Christine L.","full_name":"Schenck, Christine L.","last_name":"Schenck"},{"orcid":"0000-0002-6957-6089","last_name":"Venkataraman","first_name":"Latha","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf"},{"last_name":"Steigerwald","full_name":"Steigerwald, Michael L.","first_name":"Michael L."},{"last_name":"Nuckolls","full_name":"Nuckolls, Colin","first_name":"Colin"}],"status":"public","month":"05","_id":"18016","issue":"22","article_type":"letter_note","quality_controlled":"1","publication_status":"published"},{"author":[{"last_name":"Fatemi","full_name":"Fatemi, V.","first_name":"V."},{"last_name":"Kamenetska","full_name":"Kamenetska, M.","first_name":"M."},{"last_name":"Neaton","first_name":"J.

Solvents are found to increase the conductance of these molecular junctions by as much as 50%. Using first principles calculations, we explain this increase by showing that a shift in the Au contact work function is induced by solvents binding to undercoordinated Au sites around the junction. Increasing the Au contact work function reduces the separation between the Au Fermi energy and the highest occupied molecular orbital of BDA in the junction, increasing the measured conductance. We demonstrate that the solvent-induced shift in conductance depends on the affinity of the solvent to Au binding sites and also on the induced dipole (relative to BDA) upon adsorption. Via this mechanism, molecular junction level alignment and transport properties can be statistically altered by solvent molecule binding to the contact surface.","lang":"eng"}],"article_processing_charge":"No","pmid":1,"publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"oa_version":"None","scopus_import":"1"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.1021/nl104411f","publisher":"American Chemical Society","year":"2011","title":"A single-molecule potentiometer","extern":"1","page":"1575-1579","issue":"4","article_type":"letter_note","_id":"18018","publication_status":"published","quality_controlled":"1","author":[{"full_name":"Meisner, Jeffrey S.","first_name":"Jeffrey S.","last_name":"Meisner"},{"last_name":"Kamenetska","full_name":"Kamenetska, Masha","first_name":"Masha"},{"last_name":"Krikorian","full_name":"Krikorian, Markrete","first_name":"Markrete"},{"last_name":"Steigerwald","full_name":"Steigerwald, Michael L.","first_name":"Michael L."},{"orcid":"0000-0002-6957-6089","last_name":"Venkataraman","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","first_name":"Latha"},{"last_name":"Nuckolls","first_name":"Colin","full_name":"Nuckolls, Colin"}],"month":"03","status":"public","pmid":1,"scopus_import":"1","oa_version":"None","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"date_created":"2024-09-09T12:36:26Z","abstract":[{"text":"Controlling electron transport through a single-molecule device is key to the realization of nanoscale electronic components.

We then study systematic trends for single gold metal−molecule−metal junctions for a series of molecules terminated with amine and pyridine linkers. For all molecules studied, single molecule junctions rupture at the Au−N bond. Selective binding of the linker group allows us to correlate the N−Au bond-rupture force to the molecular backbone.

Direct metal–carbon coupling has been shown through C60, benzene and π-stacked benzene4,5,6,7, but ideally the carbon backbone of the molecule should be covalently bonded to the electrode without intervening link groups. Here, we demonstrate a method to create junctions with such contacts. Trimethyl tin (SnMe3)-terminated polymethylene chains are used to form single-molecule junctions with a break-junction technique2,3. Gold atoms at the electrode displace the SnMe3 linkers, leading to the formation of direct Au–C bonded single-molecule junctions with a conductance that is ∼100 times larger than analogous alkanes with most other terminations. The conductance of these Au–C bonded alkanes decreases exponentially with molecular length, with a decay constant of 0.97 per methylene, consistent with a non-resonant transport mechanism. Control experiments and ab initio calculations show that high conductances are achieved because a covalent Au–C sigma (σ) bond is formed. This offers a new method for making reproducible and highly conducting metal–organic contacts.","lang":"eng"}],"type":"journal_article","publication_identifier":{"eissn":["1748-3395"],"issn":["1748-3387"]},"scopus_import":"1","oa_version":"None","pmid":1,"volume":6,"language":[{"iso":"eng"}],"date_published":"2011-06-01T00:00:00Z","external_id":{"pmid":["21552252"]},"publication":"Nature Nanotechnology","OA_type":"closed access","intvolume":"         6","day":"01"},{"title":"Adaptive response and enlargement of dynamic range","type":"journal_article","year":"2011","abstract":[{"lang":"eng","text":"Many membrane channels and receptors exhibit adaptive, or desensitized, response to a strong sustained input stimulus, often supported by protein activity-dependent inactivation. Adaptive response is thought to be related to various cellular functions such as homeostasis and enlargement of dynamic range by background compensation. Here we study the quantitative relation between adaptive response and background compensation within a modeling framework. We show that any particular type of adaptive response is neither sufficient nor necessary for adaptive enlargement of dynamic range. In particular a precise adaptive response, where system activity is maintained at a constant level at steady state, does not ensure a large dynamic range neither in input signal nor in system output. A general mechanism for input dynamic range enlargement can come about from the activity-dependent modulation of protein responsiveness by multiple biochemical modification, regardless of the type of adaptive response it induces. Therefore hierarchical biochemical processes such as methylation and phosphorylation are natural candidates to induce this property in signaling systems."}],"date_created":"2018-12-11T11:54:10Z","date_updated":"2021-01-12T06:53:23Z","oa":1,"citation":{"apa":"Friedlander, T., &#38; Brenner, N.
