We report a comprehensive kinetic examination of a model carboxylate O-arylation, comparing a state-of-the-art homogeneous photocatalyst (Ir(ppy)3) with a competitive heterogeneous photocatalyst (graphitic carbon nitride). Experimental conditions were adjusted such that the nickel catalytic cycle is saturated with excited photocatalyst. This approach was designed to remove the role of the photocatalyst, by which only the intrinsic behaviors of the nickel catalytic cycles are observed. The two reactions did not display identical kinetics. Ir(ppy)3 deactivates the nickel catalytic cycle and creates more dehalogenated side product. Kinetic data for the reaction using Ir(ppy)3 supports a turnover-limiting reductive elimination. Graphitic carbon nitride gave higher selectivity, even at high photocatalyst-to-nickel ratios. The heterogeneous reaction also showed a rate dependence on aryl halide, indicating that oxidative addition plays a role in rate determination. The results argue against the current mechanistic hypothesis, which states that the photocatalyst is only involved to trigger reductive elimination."}],"intvolume":" 142"},{"oa":1,"citation":{"mla":"Gisbertz, Sebastian, et al. “Overcoming Limitations in Dual Photoredox/Nickel-Catalysed C–N Cross-Couplings Due to Catalyst Deactivation.” Nature Catalysis, vol. 3, no. 8, Springer Nature, 2020, pp. 611–20, doi:10.1038/s41929-020-0473-6.","ieee":"S.

The formation of catalytically inactive nickel-black is responsible for this limitation and causes severe reproducibility issues. Here, we demonstrate that catalyst deactivation can be avoided by using a carbon nitride photocatalyst. The broad absorption of the heterogeneous photocatalyst enables wavelength-dependent control of the rate of reductive elimination to prevent nickel-black formation during the coupling of cyclic, secondary amines and aryl halides. A second approach, which is applicable to a broader set of electron-rich aryl halides, is to run the reactions at high concentrations to increase the rate of oxidative addition. Less nucleophilic, primary amines can be coupled with electron-rich aryl halides by stabilizing low-valent nickel intermediates with a suitable additive. The developed protocols enable reproducible, selective C–N cross-couplings of electron-rich aryl bromides and can also be applied for electron-poor aryl chlorides."}],"intvolume":" 3","publication":"Nature Catalysis","main_file_link":[{"url":"https://doi.org/10.26434/chemrxiv.10298735","open_access":"1"}],"quality_controlled":"1","day":"01","date_created":"2022-08-25T11:06:16Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2020-08-01T00:00:00Z","status":"public","year":"2020","issue":"8","publisher":"Springer Nature","article_type":"original","type":"journal_article","doi":"10.1038/s41929-020-0473-6","_id":"11979","oa_version":"Preprint","extern":"1","date_updated":"2024-10-14T12:06:23Z"},{"article_number":"1387","_id":"11980","oa_version":"Published Version","doi":"10.1038/s41467-020-15131-0","extern":"1","date_updated":"2023-02-21T10:10:14Z","date_published":"2020-03-13T00:00:00Z","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2022-08-25T11:10:15Z","publisher":"Springer Nature","type":"journal_article","article_type":"original","year":"2020","title":"Dichloromethylation of enones by carbon nitride photocatalysis","publication_status":"published","intvolume":" 11","abstract":[{"lang":"eng","text":"Small organic radicals are ubiquitous intermediates in photocatalysis and are used in organic synthesis to install functional groups and to tune electronic properties and pharmacokinetic parameters of the final molecule.

Through careful tuning of the oscillator properties, the residence time distribution (RTD) was optimized, whilst maintaining a stable catalyst suspension. Short residence times (20 min) were achieved using optimized conditions and the recyclability of the photocatalyst was demonstrated over 10 cycles with no loss of activity. During a stable 4.5 hour scale-out demonstration, the model substrate could be isolated on 12 g scale (90% yield, 2.67 g h−1).

Distinct histone modifications are often associated with ON/OFF epigenetic states, but how these states are stably maintained through DNA replication, yet in certain situations switch from one to another remains unclear. Here, we address this problem through identification of Arabidopsis INCURVATA11 (ICU11) as a Polycomb Repressive Complex 2 accessory protein. ICU11 robustly immunoprecipitated in vivo with PRC2 core components and the accessory proteins, EMBRYONIC FLOWER 1 (EMF1), LIKE HETEROCHROMATIN PROTEIN1 (LHP1), and TELOMERE_REPEAT_BINDING FACTORS (TRBs). ICU11 encodes a 2-oxoglutarate-dependent dioxygenase, an activity associated with histone demethylation in other organisms, and mutant plants show defects in multiple aspects of the Arabidopsis epigenome. To investigate its primary molecular function we identified the Arabidopsis FLOWERING LOCUS C (FLC) as a direct target and found icu11 disrupted the cold-induced, Polycomb-mediated silencing underlying vernalization. icu11 prevented reduction in H3K36me3 levels normally seen during the early cold phase, supporting a role for ICU11 in H3K36me3 demethylation. This was coincident with an attenuation of H3K27me3 at the internal nucleation site in FLC, and reduction in H3K27me3 levels across the body of the gene after plants were returned to the warm. Thus, ICU11 is required for the cold-induced epigenetic switching between the mutually exclusive chromatin states at FLC, from the active H3K36me3 state to the silenced H3K27me3 state. These data support the importance of physical coupling of histone modification activities to promote epigenetic switching between opposing chromatin states.","lang":"eng"}],"intvolume":" 117","publication":"Proceedings of the National Academy of Sciences","quality_controlled":"1","day":"22","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7368280/","open_access":"1"}],"date_published":"2020-05-22T00:00:00Z","status":"public","keyword":["Multidisciplinary"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-01-16T09:15:44Z","publisher":"Proceedings of the National Academy of Sciences","article_type":"original","type":"journal_article","year":"2020","pmid":1,"issue":"28","ddc":["580"],"file":[{"access_level":"open_access","date_updated":"2023-02-07T11:29:55Z","checksum":"cedee184cb12f454f2fba4158ff47db9","file_size":1105414,"file_name":"2020_PNAS_Bloomer.pdf","file_id":"12526","creator":"alisjak","relation":"main_file","date_created":"2023-02-07T11:29:55Z","success":1,"content_type":"application/pdf"}],"_id":"12188","oa_version":"Published Version","file_date_updated":"2023-02-07T11:29:55Z","tmp":{"short":"CC BY (4.0)","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)"},"doi":"10.1073/pnas.1920621117","extern":"1","date_updated":"2023-05-08T10:53:55Z","external_id":{"pmid":["32601198"]},"department":[{"_id":"XiFe"}]},{"publisher":"Public Library of Science (PLoS)","article_type":"original","type":"journal_article","issue":"6","pmid":1,"year":"2020","date_published":"2020-06-29T00:00:00Z","status":"public","date_created":"2023-01-16T09:16:10Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Cancer Research","Genetics (clinical)","Genetics","Molecular Biology","Ecology","Evolution","Behavior and Systematics"],"external_id":{"pmid":["32598340"]},"extern":"1","date_updated":"2023-05-08T10:54:39Z","department":[{"_id":"XiFe"}],"oa_version":"Published Version","article_number":"e1008894","_id":"12189","doi":"10.1371/journal.pgen.1008894","publication_identifier":{"issn":["1553-7404"]},"month":"06","scopus_import":"1","volume":16,"language":[{"iso":"eng"}],"author":[{"full_name":"Christophorou, Nicolas","first_name":"Nicolas","last_name":"Christophorou"},{"last_name":"She","first_name":"Wenjing","full_name":"She, Wenjing"},{"last_name":"Long","first_name":"Jincheng","full_name":"Long, Jincheng"},{"full_name":"Hurel, Aurélie","last_name":"Hurel","first_name":"Aurélie"},{"full_name":"Beaubiat, Sébastien","last_name":"Beaubiat","first_name":"Sébastien"},{"full_name":"Idir, Yassir","last_name":"Idir","first_name":"Yassir"},{"full_name":"Tagliaro-Jahns, Marina","first_name":"Marina","last_name":"Tagliaro-Jahns"},{"full_name":"Chambon, Aurélie","first_name":"Aurélie","last_name":"Chambon"},{"full_name":"Solier, Victor","first_name":"Victor","last_name":"Solier"},{"first_name":"Daniel","last_name":"Vezon","full_name":"Vezon, Daniel"},{"full_name":"Grelon, Mathilde","first_name":"Mathilde","last_name":"Grelon"},{"orcid":"0000-0002-4008-1234","full_name":"Feng, Xiaoqi","last_name":"Feng","id":"e0164712-22ee-11ed-b12a-d80fcdf35958","first_name":"Xiaoqi"},{"full_name":"Bouché, Nicolas","first_name":"Nicolas","last_name":"Bouché"},{"full_name":"Mézard, Christine","last_name":"Mézard","first_name":"Christine"}],"citation":{"short":"N.

COs are unevenly distributed along chromosomes and the underlying mechanisms controlling CO localization are not well understood. We previously showed that meiotic COs are mis-localized in the absence of AXR1, an enzyme involved in the neddylation/rubylation protein modification pathway in Arabidopsis thaliana. Here, we report that in axr1-/-, male meiocytes show a strong defect in chromosome pairing whereas the formation of the telomere bouquet is not affected. COs are also redistributed towards subtelomeric chromosomal ends where they frequently form clusters, in contrast to large central regions depleted in recombination. The CO suppressed regions correlate with DNA hypermethylation of transposable elements (TEs) in the CHH context in axr1-/- meiocytes. Through examining somatic methylomes, we found axr1-/- affects DNA methylation in a plant, causing hypermethylation in all sequence contexts (CG, CHG and CHH) in TEs. Impairment of the main pathways involved in DNA methylation is epistatic over axr1-/- for DNA methylation in somatic cells but does not restore regular chromosome segregation during meiosis. Collectively, our findings reveal that the neddylation pathway not only regulates hormonal perception and CO distribution but is also, directly or indirectly, a major limiting pathway of TE DNA methylation in somatic cells."}],"intvolume":" 16","publication":"PLOS Genetics","title":"AXR1 affects DNA methylation independently of its role in regulating meiotic crossover localization","publication_status":"published"},{"external_id":{"arxiv":["1906.00632"]},"date_updated":"2024-10-09T21:05:15Z","extern":"1","doi":"10.1016/j.jnt.2019.09.003","oa_version":"Preprint","_id":"12310","issue":"4","year":"2020","article_type":"original","type":"journal_article","publisher":"Elsevier","date_created":"2023-01-16T11:45:07Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Algebra and Number Theory"],"status":"public","date_published":"2020-04-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.1906.00632"}],"day":"01","quality_controlled":"1","publication":"Journal of Number Theory","intvolume":" 209","abstract":[{"lang":"eng","text":"Let be a sequence of points on an elliptic curve defined over a number field K.

The structure of a debris cover is unique to each glacier and sensitive to climate. Despite this, debris cover has been omitted from global glacier models and forecasts of their response to a changing climate. Fundamental to resolving these omissions is a global map of debris cover and an estimate of its future spatial evolution. Here we use Landsat imagery and a detailed correction to the Randolph Glacier Inventory to show that 7.3% of mountain glacier area is debris covered and over half of Earth’s debris is concentrated in three regions: Alaska (38.6% of total debris-covered area), Southwest Asia (12.6%) and Greenland (12.0%). We use a set of new metrics, which include stage, the current position of a glacier on its trajectory towards reaching its spatial carrying capacity of debris cover, to quantify the state of glaciers. Debris cover is present on 44% of Earth’s glaciers and prominent (>1.0 km2) on 15%. Of Earth’s glaciers, 20% have a substantial percentage of debris cover for which the net stage is 36% and the bulk of individual glaciers have evolved beyond an optimal moraine configuration favourable for debris-cover expansion. Use of this dataset in global-scale models will enable improved estimates of melt over 10.6% of the global glacier domain.","lang":"eng"}],"intvolume":" 13","publication_status":"published","title":"The state of rock debris covering Earth’s glaciers","day":"02","quality_controlled":"1","author":[{"full_name":"Herreid, Sam","first_name":"Sam","last_name":"Herreid"},{"last_name":"Pellicciotti","first_name":"Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","full_name":"Pellicciotti, Francesca"}],"language":[{"iso":"eng"}],"page":"621-627","citation":{"short":"S.

Nevertheless, such information typically relies upon extrapolation from a sparse network of observations at low elevations. Here, we test the potential of high-resolution snow depth data derived from optical stereophotogrammetry of Pléiades satellites for improving the representation of snow depth initial conditions (SDICs) in a glacio-hydrological model and assess potential improvements in the skill of snowmelt and streamflow simulations in a high-elevation Andean catchment. We calibrate model parameters controlling glacier mass balance and snow cover evolution using ground-based and satellite observations, and consider the relative importance of accurate estimates of SDICs compared to model parameters and forcings. We find that Pléiades SDICs improve the simulation of snow-covered area, glacier mass balance, and monthly streamflow compared to alternative SDICs based upon extrapolation of meteorological variables or statistical methods to estimate SDICs based upon topography. Model simulations are found to be sensitive to SDICs in the early spring (up to 48% variability in modeled streamflow compared to the best estimate model), and to temperature gradients in all months that control albedo and melt rates over a large elevation range (>2,400 m). As such, appropriately characterizing the distribution of total snow volume with elevation is important for reproducing total streamflow and the proportions of snowmelt. Therefore, optical stereo-photogrammetry offers an advantage for obtaining SDICs that aid both the timing and magnitude of streamflow simulations, process representation (e.g., snow cover evolution) and has the potential for large spatial domains.","lang":"eng"}],"intvolume":" 56","publication":"Water Resources Research","publication_status":"published","title":"The utility of optical satellite winter snow depths for initializing a glacio‐hydrological model of a High‐Elevation, Andean catchment","issue":"8","year":"2020","publisher":"American Geophysical Union","type":"journal_article","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-02-20T08:12:22Z","keyword":["Water Science and Technology"],"date_published":"2020-08-01T00:00:00Z","status":"public","extern":"1","date_updated":"2023-02-28T12:41:45Z","doi":"10.1029/2020wr027188","oa_version":"Published Version","_id":"12594","article_number":"e2020WR027188"},{"doi":"10.3390/rs12152389","article_number":"2389","_id":"12595","oa_version":"Published Version","extern":"1","date_updated":"2023-02-28T12:36:22Z","date_created":"2023-02-20T08:12:29Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2020-07-24T00:00:00Z","status":"public","year":"2020","issue":"15","publisher":"MDPI","type":"journal_article","article_type":"original","title":"Seasonal dynamics of a temperate Tibetan glacier revealed by high-resolution UAV photogrammetry and in situ measurements","publication_status":"published","intvolume":" 12","abstract":[{"lang":"eng","text":"The seasonal dynamic changes of Tibetan glaciers have seen little prior investigation, despite the increase in geodetic studies of multi-year changes.

Over an annual timescale, surface lowering was greatly suppressed by the resupply of ice from the glacier’s accumulation area—the annual emergence velocity compensates for about 55% of surface ablation in our study area. Cold season emergence velocities (3.0 ± 1.2 m) were ~5-times larger than those observed in the warm season (0.6 ± 1.0 m). Distinct spring precipitation patterns may contribute to these distinct seasonal signals. Such seasonal dynamic conditions are possibly critical for different glacier responses to climate change in this region of the Tibetan Plateau, and perhaps further afield."}],"publication":"Remote Sensing","main_file_link":[{"url":"https://doi.org/10.3390/rs12152389","open_access":"1"}],"quality_controlled":"1","day":"24","oa":1,"citation":{"chicago":"Yang, Wei, Chuanxi Zhao, Matthew Westoby, Tandong Yao, Yongjie Wang, Francesca Pellicciotti, Jianmin Zhou, Zhen He, and Evan Miles. “Seasonal Dynamics of a Temperate Tibetan Glacier Revealed by High-Resolution UAV Photogrammetry and in Situ Measurements.” Remote Sensing.

We investigate glacier runoff in the period 1955–2016 in the Maipo River basin (4843 km2, 33.0–34.3∘ S, 69.8–70.5∘ W), in the semiarid Andes of Chile. The basin contains more than 800 glaciers, which cover 378 km2 in total (inventoried in 2000). We model the mass balance and runoff contribution of 26 glaciers with the physically oriented and fully distributed TOPKAPI (Topographic Kinematic Approximation and Integration)-ETH glacio-hydrological model and extrapolate the results to the entire basin. TOPKAPI-ETH is run at a daily time step using several glaciological and meteorological datasets, and its results are evaluated against streamflow records, remotely sensed snow cover, and geodetic mass balances for the periods 1955–2000 and 2000–2013. Results show that in 1955–2016 glacier mass balance had a general decreasing trend as a basin average but also had differences between the main sub-catchments. Glacier volume decreased by one-fifth (from 18.6±4.5 to 14.9±2.9 km3). Runoff from the initially glacierized areas was 177±25 mm yr−1 (16±7 % of the total contributions to the basin), but it shows a decreasing sequence of maxima, which can be linked to the interplay between a decrease in precipitation since the 1980s and the reduction of ice melt. Glaciers in the Maipo River basin will continue retreating because they are not in equilibrium with the current climate. In a hypothetical constant climate scenario, glacier volume would reduce to 81±38 % of the year 2000 volume, and glacier runoff would be 78±30 % of the 1955–2016 average. This would considerably decrease the drought mitigation capacity of the basin."}],"publication_identifier":{"issn":["1994-0424"]},"volume":14,"scopus_import":"1","month":"06","page":"2005-2027","citation":{"ieee":"Á.

The dataset consists of a 10-year (2005–2014) meteorological record along the glacier centreline up to an upper glacier cirque, spanning an elevation difference of 900 m. We test the validity of on-glacier linear lapse rates, and a model that calculates Ta based on the influence of katabatic winds and other heat sources along the glacier flow line. During the coldest hours of each summer (10% of time), average lapse rates across the entire glacier range from −4.7 to −6.7°C km−1, with a strong relationship between Ta and elevation (R2 > 0.7). During warm conditions, Ta shows more complex, non-linear patterns that are better explained by the flow line-dependent model, reducing errors by up to 0.5°C compared with linear lapse rates, although more uncertainty might be associated with these observations due to occasionally poor sensor ventilation. We conclude that Ta spatial distribution can vary significantly from year to year, and from one glacier section to another. Importantly, extrapolations using linear lapse rates from the ablation zone might lead to large underestimations of Ta on the upper glacier areas.","lang":"eng"}],"publication_status":"published","title":"Modelling spatial patterns of near-surface air temperature over a decade of melt seasons on McCall Glacier, Alaska","main_file_link":[{"url":"https://doi.org/10.1017/jog.2020.12","open_access":"1"}],"day":"01","quality_controlled":"1"},{"main_file_link":[{"url":"https://doi.org/10.1029/2019WR024880","open_access":"1"}],"quality_controlled":"1","day":"01","publication_status":"published","title":"Snow depth patterns in a high mountain Andean catchment from satellite optical tristereoscopic remote sensing","abstract":[{"text":"Obtaining detailed information about high mountain snowpacks is often limited by insufficient ground-based observations and uncertainty in the (re)distribution of solid precipitation. We utilize high-resolution optical images from Pléiades satellites to generate a snow depth map, at a spatial resolution of 4 m, for a high mountain catchment of central Chile. Results are negatively biased (median difference of −0.22 m) when compared against observations from a terrestrial Light Detection And Ranging scan, though replicate general snow depth variability well. Additionally, the Pléiades dataset is subject to data gaps (17% of total pixels), negative values for shallow snow (12%), and noise on slopes >40–50° (2%). We correct and filter the Pléiades snow depths using surface classification techniques of snow-free areas and a random forest model for data gap filling. Snow depths (with an estimated error of ~0.36 m) average 1.66 m and relate well to topographical parameters such as elevation and northness in a similar way to previous studies. However, estimations of snow depth based upon topography (TOPO) or physically based modeling (DBSM) cannot resolve localized processes (i.e., avalanching or wind scouring) that are detected by Pléiades, even when forced with locally calibrated data. Comparing these alternative model approaches to corrected Pléiades snow depths reveals total snow volume differences between −28% (DBSM) and +54% (TOPO) for the catchment and large differences across most elevation bands. Pléiades represents an important contribution to understanding snow accumulation at sparsely monitored catchments, though ideally requires a careful systematic validation procedure to identify catchment-scale biases and errors in the snow depth derivation.","lang":"eng"}],"intvolume":" 56","publication":"Water Resources Research","month":"02","scopus_import":"1","volume":56,"publication_identifier":{"issn":["0043-1397"],"eissn":["1944-7973"]},"oa":1,"citation":{"ama":"Shaw TE, Gascoin S, Mendoza PA, Pellicciotti F, McPhee J.

Primarily, colorless phylloleucobilins featuring four deconjugated pyrrole units were identified. Their yellow counterparts, phylloxanthobilins, were discovered more recently. Although the two catabolites differ only by one double bond, physicochemical properties are very distinct. Moreover, the presence of the double bond seems to enhance physiologically relevant bioactivities: in contrast to phylloleucobilin, we identified a potent anti-proliferative activity for a phylloxanthobilin, and show that this natural product induces apoptotic cell death and a cell cycle arrest in cancer cells. Interestingly, upon modifying inactive phylloleucobilin by esterification, an anti-proliferative activity can be observed that increases with the chain lengths of the alkyl esters. We provide first evidence for anti-cancer activity of phyllobilins, report a novel plant source for a phylloxanthobilin, and by using paper spray MS, show that these bioactive yellow chlorophyll catabolites are more prevalent in Nature than previously assumed."}],"intvolume":" 2020","title":"Phylloxanthobilins are abundant linear tetrapyrroles from chlorophyll breakdown with activities against cancer cells","publication_status":"published","day":"09","quality_controlled":"1","main_file_link":[{"url":"https://doi.org/10.1002/ejoc.202000692","open_access":"1"}],"status":"public","date_published":"2020-08-09T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-05-10T14:49:30Z","keyword":["Organic Chemistry","Physical and Theoretical Chemistry"],"type":"journal_article","article_type":"original","publisher":"Wiley","issue":"29","year":"2020","oa_version":"Published Version","_id":"12939","doi":"10.1002/ejoc.202000692","date_updated":"2023-05-15T07:57:14Z","extern":"1"},{"year":"2020","pmid":1,"issue":"21","type":"journal_article","article_type":"letter_note","publisher":"American Chemical Society","keyword":["Analytical Chemistry"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-05-10T14:50:19Z","status":"public","date_published":"2020-10-16T00:00:00Z","date_updated":"2023-05-15T08:01:20Z","extern":"1","external_id":{"pmid":["33063994"]},"doi":"10.1021/acs.analchem.0c02615","_id":"12940","oa_version":"Published Version","volume":92,"scopus_import":"1","month":"10","publication_identifier":{"issn":["0003-2700","1520-6882"]},"oa":1,"page":"14314-14318","citation":{"apa":"Meisenbichler, C., Kluibenschedl, F., & Müller, T.

However, every single method has its limitation in terms of polarity and molecular weight of analyte molecules. After the miniaturization of every possible component of the different ion sources, we finally were able to embed two emitters and an ion transfer tubing into a small, hand-held device. The pen-like interface is connected to the mass spectrometer and a separate control unit via a bundle of flexible tubing and cables. The novel device allows the user to ionize an extended range of chemicals by simple switching between DESI, voltage-free EASI, or LTP ionization as well as to freely move the interface over a surface of interest. A mini camera, which is mounted on the tip of the pen, magnifies the desorption area and enables a simple positioning of the pen. The interface was successfully tested using different types of chemicals, pharmaceuticals, and real life samples. Moreover, the combination of optical data from the camera module and chemical data obtained by mass analysis facilitates a novel type of imaging mass spectrometry, which we name “interactive mass spectrometry imaging (IMSI)”.","lang":"eng"}],"intvolume":" 92"},{"tmp":{"short":"CC BY (4.0)","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)"},"doi":"10.5281/ZENODO.3961561","_id":"13056","title":"Converting microwave and telecom photons with a silicon photonic nanomechanical interface","corr_author":"1","oa_version":"Published Version","abstract":[{"lang":"eng","text":"This datasets comprises all data shown in plots of the submitted article \"Converting microwave and telecom photons with a silicon photonic nanomechanical interface\".

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."}],"oa_version":"Published Version","tmp":{"short":"CC0 (1.0)","image":"/images/cc_0.png","legal_code_url":"https://creativecommons.org/publicdomain/zero/1.0/legalcode","name":"Creative Commons Public Domain Dedication (CC0 1.0)"},"doi":"10.5061/DRYAD.CRJDFN318","type":"research_data_reference","publisher":"Dryad","year":"2020","license":"https://creativecommons.org/publicdomain/zero/1.0/","month":"12","ddc":["570"],"status":"public","citation":{"apa":"Milutinovic, B., Stock, M., Grasse, A.
