In the same step, the chosen node picks a random neighbor, and the two nodes balance their loads by averaging them. We are interested in the expected gap between the minimum and maximum loads at nodes as the process progresses, and its dependence on n and on the graph structure. Variants of the above graphical balanced allocation process have been studied previously by Peres, Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and Sun, 2015]. These authors left as open the question of characterizing the gap in the case of cycle graphs in the dynamic case, where weights are created during the algorithm’s execution. For this case, the only known upper bound is of 𝒪(n log n), following from a majorization argument due to [Peres et al., 2015], which analyzes a related graphical allocation process. In this paper, we provide an upper bound of 𝒪 (√n log n) on the expected gap of the above process for cycles of length n. We introduce a new potential analysis technique, which enables us to bound the difference in load between k-hop neighbors on the cycle, for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds the maximum value of the gap by bounding its value across all possible subsets of a certain structure, and recursively bounding the gaps within each subset. We provide analytical and experimental evidence that our upper bound on the gap is tight up to a logarithmic factor."}],"citation":{"apa":"Alistarh, D.-A., Nadiradze, G., & Sabour, A. (2020).

Whilst multiple infections are intensively studied in solitary hosts, it is so far unresolved how social host interactions interfere with pathogen competition, and if this depends on coinfection diversity. We studied how the collective disease defenses of ants – their social immunity – influence pathogen competition in coinfections of same or different fungal pathogen species. Social immunity reduced virulence for all pathogen combinations, but interfered with spore production only in different-species coinfections. Here, it decreased overall pathogen sporulation success, whilst simultaneously increasing co-sporulation on individual cadavers and maintaining a higher pathogen diversity at the community-level. Mathematical modeling revealed that host sanitary care alone can modulate competitive outcomes between pathogens, giving advantage to fast-germinating, thus less grooming-sensitive ones. Host social interactions can hence modulate infection dynamics in coinfected group members, thereby altering pathogen communities at the host- and population-level.","lang":"eng"}],"year":"2020","article_processing_charge":"No","license":"https://creativecommons.org/publicdomain/zero/1.0/","department":[{"_id":"SyCr"},{"_id":"KrCh"}],"date_updated":"2023-09-05T16:04:48Z","oa":1,"author":[{"first_name":"Barbara","id":"2CDC32B8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8214-4758","last_name":"Milutinovic","full_name":"Milutinovic, Barbara"},{"id":"42462816-F248-11E8-B48F-1D18A9856A87","first_name":"Miriam","last_name":"Stock","full_name":"Stock, Miriam"},{"id":"406F989C-F248-11E8-B48F-1D18A9856A87","first_name":"Anna V","last_name":"Grasse","full_name":"Grasse, Anna V"},{"last_name":"Naderlinger","id":"31757262-F248-11E8-B48F-1D18A9856A87","first_name":"Elisabeth","full_name":"Naderlinger, Elisabeth"},{"last_name":"Hilbe","orcid":"0000-0001-5116-955X","first_name":"Christian","id":"2FDF8F3C-F248-11E8-B48F-1D18A9856A87","full_name":"Hilbe, Christian"},{"orcid":"0000-0002-2193-3868","last_name":"Cremer","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","first_name":"Sylvia","full_name":"Cremer, Sylvia"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Social immunity modulates competition between coinfecting pathogens","month":"12","date_published":"2020-12-19T00:00:00Z","publisher":"Dryad"},{"month":"10","date_published":"2020-10-19T00:00:00Z","publisher":"Dryad","date_updated":"2023-08-04T11:19:26Z","oa":1,"author":[{"full_name":"Arnoux, Stephanie","last_name":"Arnoux","first_name":"Stephanie"},{"first_name":"Christelle","id":"32DF5794-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8441-5075","last_name":"Fraisse","full_name":"Fraisse, Christelle"},{"full_name":"Sauvage, Christopher","first_name":"Christopher","last_name":"Sauvage"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"VCF files of synonymous SNPs related to: Genomic inference of complex domestication histories in three Solanaceae species","article_processing_charge":"No","department":[{"_id":"NiBa"}],"year":"2020","citation":{"ama":"Arnoux S, Fraisse C, Sauvage C.

Reconstructing historical gene flow, effective population size changes and their timing is therefore of fundamental interest to understand how plant demography and human selection jointly shape genomic divergence during domestication. Yet, the comparison under a single statistical framework of independent domestication histories across different crop species has been little evaluated so far. Thus, it is unclear whether domestication leads to convergent demographic changes that similarly affect crop genomes. To address this question, we used existing and new transcriptome data on three crop species of Solanaceae (eggplant, pepper and tomato), together with their close wild relatives. We fitted twelve demographic models of increasing complexity on the unfolded joint allele frequency spectrum for each wild/crop pair, and we found evidence for both shared and species-specific demographic processes between species. A convergent history of domestication with gene-flow was inferred for all three species, along with evidence of strong reduction in the effective population size during the cultivation stage of tomato and pepper. The absence of any reduction in size of the crop in eggplant stands out from the classical view of the domestication process; as does the existence of a “protracted period” of management before cultivation. Our results also suggest divergent management strategies of modern cultivars among species as their current demography substantially differs. Finally, the timing of domestication is species-specific and supported by the few historical records available.","lang":"eng"}],"_id":"13065","tmp":{"short":"CC0 (1.0)","image":"/images/cc_0.png","name":"Creative Commons Public Domain Dedication (CC0 1.0)","legal_code_url":"https://creativecommons.org/publicdomain/zero/1.0/legalcode"},"ddc":["570"],"date_created":"2023-05-23T16:30:20Z","day":"19","status":"public","main_file_link":[{"url":"https://doi.org/10.5061/dryad.q2bvq83hd","open_access":"1"}],"doi":"10.5061/DRYAD.Q2BVQ83HD","related_material":{"link":[{"relation":"software","url":"https://github.com/starnoux/arnoux_et_al_2019"}],"record":[{"relation":"used_in_publication","status":"public","id":"8928"}]},"oa_version":"Published Version"},{"oa_version":"Published Version","related_material":{"record":[{"id":"8755","status":"public","relation":"used_in_publication"}]},"doi":"10.5281/ZENODO.4052882","main_file_link":[{"url":"https://doi.org/10.5281/zenodo.4052883","open_access":"1"}],"status":"public","day":"27","date_created":"2023-05-23T16:42:30Z","tmp":{"image":"/images/cc_by.png","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)"},"_id":"13070","ddc":["530"],"abstract":[{"lang":"eng","text":"This dataset comprises all data shown in the figures of the submitted article \"Surpassing the resistance quantum with a geometric superinductor\".

This allows us to study \"replicated\" instances of secondary contact between closely-related species. Previous work on this complex has shown that local introgression is both widespread and highly heterogeneous, and has identified SNPs that are outliers of differentiation between lineages. Here, we developed an ancestry-informative panel of such SNPs. We then compared their frequencies in newly-sampled populations, including samples from within the hybrid zones, and parental populations at different distances from the contact. Results show that close to the hybrid zones, some outlier loci are near to fixation for the heterospecific allele, suggesting enhanced local introgression, or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses, treating local parental populations as the reference, reveal a globally high concordance among loci, albeit with a few signals of asymmetric introgression. Enhanced local introgression at specific loci is consistent with the early transfer of adaptive variants after contact, possibly including asymmetric bi-stable variants (Dobzhansky-Muller incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having escaped one barrier, however, these variants can be trapped or delayed at the next barrier, confining the introgression locally. These results shed light on the decay of species barriers during phases of contact."}],"citation":{"ama":"Simon A, Fraisse C, El Ayari T, et al.

Bacteriorhodopsin, for example, is a protein embedded within archaeal cell membranes that binds the chromophore retinal within its hydrophobic pocket. Exposure to light triggers regioselective photoisomerization of the confined retinal, which in turn initiates a cascade of conformational changes within the protein, triggering proton flux against the concentration gradient, providing the microorganisms with the energy to live. We are inspired by these functions in nature to harness light energy using synthetic photoswitches under confinement. Like retinal, synthetic photoswitches require some degree of conformational flexibility to isomerize. In nature, the conformational change associated with retinal isomerization is accommodated by the structural flexibility of the opsin host, yet it results in steric communication between the chromophore and the protein. Similarly, we strive to design systems wherein isomerization of confined photoswitches results in steric communication between a photoswitch and its confining environment. To achieve this aim, a balance must be struck between molecular crowding and conformational freedom under confinement: too much crowding prevents switching, whereas too much freedom resembles switching of isolated molecules in solution, preventing communication.\r\n\r\nIn this Account, we discuss five classes of synthetic light-switchable compounds—diarylethenes, anthracenes, azobenzenes, spiropyrans, and donor–acceptor Stenhouse adducts—comparing their behaviors under confinement and in solution. The environments employed to confine these photoswitches are diverse, ranging from planar surfaces to nanosized cavities within coordination cages, nanoporous frameworks, and nanoparticle aggregates. The trends that emerge are primarily dependent on the nature of the photoswitch and not on the material used for confinement. In general, we find that photoswitches requiring less conformational freedom for switching are, as expected, more straightforward to isomerize reversibly under confinement. Because these compounds undergo only small structural changes upon isomerization, however, switching does not propagate into communication with their environment. Conversely, photoswitches that require more conformational freedom are more challenging to switch under confinement but also can influence system-wide behavior.\r\n\r\nAlthough we are primarily interested in the effects of geometric constraints on photoswitching under confinement, additional effects inevitably emerge when a compound is removed from solution and placed within a new, more crowded environment. For instance, we have found that compounds that convert to zwitterionic isomers upon light irradiation often experience stabilization of these forms under confinement. This effect results from the mutual stabilization of zwitterions that are brought into close proximity on surfaces or within cavities. Furthermore, photoswitches can experience preorganization under confinement, influencing the selectivity and efficiency of their photoreactions. Because intermolecular interactions arising from confinement cannot be considered independently from the effects of geometric constraints, we describe all confinement effects concurrently throughout this Account."}],"scopus_import":"1","publication_identifier":{"issn":["0001-4842"],"eissn":["1520-4898"]},"extern":"1","citation":{"chicago":"Grommet, Angela B., Lucia M.

For instance, the optical properties of BODIPY dyes are inherently related to the degree of aggregation and the mutual orientation of BODIPY units within these aggregates. Whereas the noncovalent aggregation of various BODIPY dyes has been studied in diverse media, the ill-defined nature of these aggregates has made it difficult to elucidate the structure–property relationships. Here, we studied the encapsulation of three structurally simple BODIPY derivatives within the hydrophobic cavity of a water-soluble, flexible PdII6L4 coordination cage. The cavity size allowed for the selective encapsulation of two dye molecules, irrespective of the substitution pattern on the BODIPY core. Working with a model, a pentamethyl-substituted derivative, we found that the mutual orientation of two BODIPY units in the cage’s cavity was remarkably similar to that in the crystalline state of the free dye, allowing us to isolate and characterize the smallest possible noncovalent H-type BODIPY aggregate, namely, an H-dimer. Interestingly, a CF3-substituted BODIPY, known for forming J-type aggregates, was also encapsulated as an H-dimer. Taking advantage of the dynamic nature of encapsulation, we developed a system in which reversible switching between H- and J-aggregates can be induced for multiple cycles simply by addition and subsequent destruction of the cage. We expect that the ability to rapidly and reversibly manipulate the optical properties of supramolecular inclusion complexes in aqueous media will open up avenues for developing detection systems that operate within biological environments."}],"type":"journal_article","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"citation":{"chicago":"Gemen, Julius, Johannes Ahrens, Linda J.

Conversion between DHP and CPD is thought to proceed via a biradical intermediate; bimolecular events involving this unstable intermediate thus result in rapid decomposition and poor cycling performance. Here, we show that the reversible isomerization of DHP can be stabilized upon confinement within a PdII6L4 coordination cage. By protecting this reactive intermediate using the cage, each isomerization reaction proceeds to higher yield, which significantly decreases the fatigue experienced by the system upon repeated photocycling. Although molecular confinement is known to help stabilize reactive species, this effect is not typically employed to protect reactive intermediates and thus improve reaction yields. We envisage that performing reactions under confinement will not only improve the cyclic performance of photochromic molecules, but may also increase the amount of product obtainable from traditionally low-yielding organic reactions.","lang":"eng"}],"scopus_import":"1","language":[{"iso":"eng"}],"article_type":"original","article_processing_charge":"No","title":"Improving fatigue resistance of dihydropyrene by encapsulation within a coordination cage","author":[{"full_name":"Canton, Martina","first_name":"Martina","last_name":"Canton"},{"first_name":"Angela B.","last_name":"Grommet","full_name":"Grommet, Angela B."},{"full_name":"Pesce, Luca","last_name":"Pesce","first_name":"Luca"},{"full_name":"Gemen, Julius","last_name":"Gemen","first_name":"Julius"},{"last_name":"Li","first_name":"Shiming","full_name":"Li, Shiming"},{"first_name":"Yael","last_name":"Diskin-Posner","full_name":"Diskin-Posner, Yael"},{"full_name":"Credi, Alberto","first_name":"Alberto","last_name":"Credi"},{"full_name":"Pavan, Giovanni M.","last_name":"Pavan","first_name":"Giovanni M."},{"last_name":"Andréasson","first_name":"Joakim","full_name":"Andréasson, Joakim"},{"full_name":"Klajn, Rafal","last_name":"Klajn","first_name":"Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Chemical Society"},{"article_type":"original","language":[{"iso":"eng"}],"article_processing_charge":"No","author":[{"first_name":"Luca","last_name":"Pesce","full_name":"Pesce, Luca"},{"full_name":"Perego, Claudio","last_name":"Perego","first_name":"Claudio"},{"first_name":"Angela B.","last_name":"Grommet","full_name":"Grommet, Angela B."},{"full_name":"Klajn, Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","first_name":"Rafal","last_name":"Klajn"},{"full_name":"Pavan, Giovanni M.","first_name":"Giovanni M.","last_name":"Pavan"}],"title":"Molecular factors controlling the isomerization of Azobenzenes in the cavity of a flexible coordination cage","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Chemical Society","publication_status":"published","quality_controlled":"1","_id":"13365","scopus_import":"1","abstract":[{"lang":"eng","text":"Photoswitchable molecules are employed for many applications, from the development of active materials to the design of stimuli-responsive molecular systems and light-powered molecular machines. To fully exploit their potential, we must learn ways to control the mechanism and kinetics of their photoinduced isomerization. One possible strategy involves confinement of photoresponsive switches such as azobenzenes or spiropyrans within crowded molecular environments, which may allow control over their light-induced conversion. However, the molecular factors that influence and control the switching process under realistic conditions and within dynamic molecular regimes often remain difficult to ascertain. As a case study, here we have employed molecular models to probe the isomerization of azobenzene guests within a Pd(II)-based coordination cage host in water. Atomistic molecular dynamics and metadynamics simulations allow us to characterize the flexibility of the cage in the solvent, the (rare) guest encapsulation and release events, and the relative probability/kinetics of light-induced isomerization of azobenzene analogues in these host–guest systems. In this way, we can reconstruct the mechanism of azobenzene switching inside the cage cavity and explore key molecular factors that may control this event. We obtain a molecular-level insight on the effects of crowding and host–guest interactions on azobenzene isomerization. The detailed picture elucidated by this study may enable the rational design of photoswitchable systems whose reactivity can be controlled via host–guest interactions."}],"type":"journal_article","publication_identifier":{"issn":["0002-7863"],"eissn":["1520-5126"]},"citation":{"chicago":"Pesce, Luca, Claudio Perego, Angela B.

However, strong evidence suggests the binary fraction of massive stars is ≳70%. Moreover, simulations so far have yielded values of fesc falling only on the lower end of the ∼10%–20% range, the amount presumed necessary to reionize the universe. Analyzing a high-resolution (4 pc) cosmological radiation-hydrodynamic simulation, we study how fesc changes when we include two different products of binary stellar evolution—stars stripped of their hydrogen envelopes and massive blue stragglers. Both produce significant amounts of ionizing photons 10–200 Myr after each starburst. We find the relative importance of these photons to be amplified with respect to escaped ionizing photons, because peaks in star formation rates (SFRs) and fesc are often out of phase by this 10–200 Myr. Additionally, low-mass, bursty galaxies emit Lyman continuum radiation primarily from binary products when SFRs are low. Observations of these galaxies by the James Webb Space Telescope could provide crucial information on the evolution of binary stars as a function of redshift. Overall, including stripped stars and massive blue stragglers increases our photon-weighted mean escape fraction ($\\langle {f}_{\\mathrm{esc}}\\rangle $) by ∼13% and ∼10%, respectively, resulting in $\\langle {f}_{\\mathrm{esc}}\\rangle =17 \\% $.

Here, we focus on pulsational pair-instability evolution, which can result in signatures that are observable with electromagnetic and gravitational waves. We simulated grids of bare helium stars to characterize the resulting black hole (BH) masses together with the ejecta composition, velocity, and thermal state. We find that the stars do not react “elastically” to the thermonuclear ignition in the core: there is not a one-to-one correspondence between pair-instability driven ignition and mass ejections, which causes ambiguity as to what is an observable pulse. In agreement with previous studies, we find that for initial helium core masses of 37.5 M⊙ ≲ MHe, init ≲ 41 M⊙, corresponding to carbon-oxygen core masses 27.5 M⊙ ≲ MCO ≲ 30.1 M⊙, the explosions are not strong enough to affect the surface. With increasing initial helium core mass, they become progressively stronger causing first large radial expansion (41 M⊙ ≲ MHe, init ≲ 42 M⊙, corresponding to 30.1 M⊙ ≲ MCO ≲ 30.8 M⊙) and, finally, also mass ejection episodes (for MHe, init ≳ 42 M⊙, or MCO ≳ 30.8 M⊙). The lowest mass helium core to be fully disrupted in a pair-instability supernova is MHe, init ≃ 80 M⊙, corresponding to MCO ≃ 55 M⊙. Models with MHe, init ≳ 200 M⊙ (MCO ≳ 114 M⊙) reach the photodisintegration regime, resulting in BHs with masses of MBH ≳ 125 M⊙. Although this is currently considered unlikely, if BHs from these models form via (weak) explosions, the previously-ejected material might be hit by the blast wave and convert kinetic energy into observable electromagnetic radiation. We characterize the hydrogen-free circumstellar material from the pulsational pair-instability of helium cores by simply assuming that the ejecta maintain a constant velocity after ejection. We find that our models produce helium-rich ejecta with mass of 10−3 M⊙ ≲ MCSM ≲ 40 M⊙, the larger values corresponding to the more massive progenitor stars. These ejecta are typically launched at a few thousand km s−1 and reach distances of ∼1012 − 1015 cm before the core-collapse of the star. The delays between mass ejection events and the final collapse span a wide and mass-dependent range (from subhour to 104 years), and the shells ejected can also collide with each other, powering supernova impostor events before the final core-collapse. The range of properties we find suggests a possible connection with (some) type Ibn supernovae."}],"type":"journal_article","_id":"13463","quality_controlled":"1","publication_status":"published","date_published":"2020-08-12T00:00:00Z","month":"08","intvolume":" 640","article_number":"A56","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"date_updated":"2023-08-09T12:58:41Z","oa":1,"external_id":{"arxiv":["2002.05077"]},"year":"2020","volume":640,"date_created":"2023-08-03T10:12:58Z","day":"12","status":"public","publication":"Astronomy & Astrophysics","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1051/0004-6361/202037710"}],"doi":"10.1051/0004-6361/202037710","oa_version":"Published Version"}]
