Here, we combine comparative genomics, transcriptomics and proteomics to obtain a complete overview of the evolution of gene dosage on the Z-chromosome of Schistosoma parasites. We compare the Z-chromosome gene content of African (Schistosoma mansoni and S. haematobium) and Asian (S. japonicum) schistosomes and describe lineage-specific evolutionary strata. We use these to assess gene expression evolution following sex-linkage. The resulting patterns suggest a reduction in expression of Z-linked genes in females, combined with upregulation of the Z in both sexes, in line with the first step of Ohno’s classic model of dosage compensation evolution. Quantitative proteomics suggest that post-transcriptional mechanisms do not play a major role in balancing the expression of Z-linked genes.

The Reynolds number ( ) for which turbulence first appears in a given experiment – the ‘natural transition point’ – depends on imperfections of the set-up, or, more precisely, on the magnitude of finite amplitude perturbations. At onset, turbulence typically only occupies a certain fraction of the flow, and this fraction equally is found to differ from experiment to experiment. Despite these findings, Reynolds proposed that after sufficiently long times, flows may settle to steady conditions: below a critical velocity, flows should (regardless of initial conditions) always return to laminar, while above this velocity, eddying motion should persist. As will be shown, even in pipes several thousand diameters long, the spatio-temporal intermittent flow patterns observed at the end of the pipe strongly depend on the initial conditions, and there is no indication that different flow patterns would eventually settle to a (statistical) steady state. Exploiting the fact that turbulent puffs do not age (i.e. they are memoryless), we continuously recreate the puff sequence exiting the pipe at the pipe entrance, and in doing so introduce periodic boundary conditions for the puff pattern. This procedure allows us to study the evolution of the flow patterns for arbitrary long times, and we find that after times in excess of advective time units, indeed a statistical steady state is reached. Although the resulting flows remain spatio-temporally intermittent, puff splitting and decay rates eventually reach a balance, so that the turbulent fraction fluctuates around a well-defined level which only depends on . In accordance with Reynolds’ proposition, we find that at lower (here 2020), flows eventually always resume to laminar, while for higher ( ), turbulence persists. The critical point for pipe flow hence falls in the interval of $2020 , which is in very good agreement with the recently proposed value of . The latter estimate was based on single-puff statistics and entirely neglected puff interactions. Unlike in typical contact processes where such interactions strongly affect the percolation threshold, in pipe flow, the critical point is only marginally influenced. Interactions, on the other hand, are responsible for the approach to the statistical steady state. As shown, they strongly affect the resulting flow patterns, where they cause ‘puff clustering’, and these regions of large puff densities are observed to travel across the puff pattern in a wave-like fashion.","lang":"eng"}],"oa_version":"Preprint","project":[{"grant_number":"306589","_id":"25152F3A-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Decoding the complexity of turbulence at its origin"}],"department":[{"_id":"BjHo"}],"external_id":{"arxiv":["1709.06372"],"isi":["000437858300003"]},"quality_controlled":"1","date_updated":"2026-07-28T14:02:09Z","intvolume":"       839","date_published":"2018-03-25T00:00:00Z","publication":"Journal of Fluid Mechanics","article_processing_charge":"No","scopus_import":"1","fulldoi":"https://doi.org/10.1017/jfm.2017.923","doi":"10.1017/jfm.2017.923","date_created":"2019-02-14T12:50:50Z","publication_status":"published","article_type":"original","year":"2018"},{"type":"dissertation","author":[{"last_name":"Kolesnikov","first_name":"Alexander","full_name":"Kolesnikov, Alexander","id":"2D157DB6-F248-11E8-B48F-1D18A9856A87"}],"file_date_updated":"2020-07-14T12:45:22Z","citation":{"ama":"Kolesnikov A.

Moreover, very recently computer vision research widely adopted techniques for representation learning, which further increase the demand for labeled data. However, for many important practical problems there is relatively small amount of labeled data available, so it is problematic to leverage full potential of the representation learning methods. One way to overcome this obstacle is to invest substantial resources into producing large labelled datasets. Unfortunately, this can be prohibitively expensive in practice. In this thesis we focus on the alternative way of tackling the aforementioned issue. We concentrate on methods, which make use of weakly-labeled or even unlabeled data. Specifically, the first half of the thesis is dedicated to the semantic image segmentation task. We develop a technique, which achieves competitive segmentation performance and only requires annotations in a form of global image-level labels instead of dense segmentation masks. Subsequently, we present a new methodology, which further improves segmentation performance by leveraging tiny additional feedback from a human annotator. By using our methods practitioners can greatly reduce the amount of data annotation effort, which is required to learn modern image segmentation models. In the second half of the thesis we focus on methods for learning from unlabeled visual data. We study a family of autoregressive models for modeling structure of natural images and discuss potential applications of these models. Moreover, we conduct in-depth study of one of these applications, where we develop the state-of-the-art model for the probabilistic image colorization task.","lang":"eng"}],"ec_funded":1,"oa_version":"Published Version","project":[{"grant_number":"308036","_id":"2532554C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Lifelong Learning of Visual Scene Understanding"}],"department":[{"_id":"ChLa"},{"_id":"GradSch"}],"alternative_title":["ISTA Thesis"],"doi_confirm":"1","date_updated":"2026-07-29T13:22:05Z","publist_id":"7718","date_published":"2018-05-25T00:00:00Z","article_processing_charge":"No","supervisor":[{"last_name":"Lampert","first_name":"Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","full_name":"Lampert, Christoph"}],"fulldoi":"https://doi.org/10.15479/AT:ISTA:th_1021","doi":"10.15479/AT:ISTA:th_1021","publication_status":"published","date_created":"2018-12-11T11:45:09Z","year":"2018"},{"OA_place":"publisher","degree_awarded":"PhD","has_accepted_license":"1","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","title":"Multiple covers with balls","corr_author":"1","status":"public","day":"11","month":"06","oa_version":"Published Version","_id":"201","abstract":[{"text":"We describe arrangements of three-dimensional spheres from a geometrical and topological point of view. Real data (fitting this setup) often consist of soft spheres which show certain degree of deformation while strongly packing against each other. In this context, we answer the following questions: If we model a soft packing of spheres by hard spheres that are allowed to overlap, can we measure the volume in the overlapped areas? Can we be more specific about the overlap volume, i.e. quantify how much volume is there covered exactly twice, three times, or k times? What would be a good optimization criteria that rule the arrangement of soft spheres while making a good use of the available space? Fixing a particular criterion, what would be the optimal sphere configuration? The first result of this thesis are short formulas for the computation of volumes covered by at least k of the balls. The formulas exploit information contained in the order-k Voronoi diagrams and its closely related Level-k complex. The used complexes lead to a natural generalization into poset diagrams, a theoretical formalism that contains the order-k and degree-k diagrams as special cases. In parallel, we define different criteria to determine what could be considered an optimal arrangement from a geometrical point of view. Fixing a criterion, we find optimal soft packing configurations in 2D and 3D where the ball centers lie on a lattice. As a last step, we use tools from computational topology on real physical data, to show the potentials of higher-order diagrams in the description of melting crystals. The results of the experiments leaves us with an open window to apply the theories developed in this thesis in real applications.","lang":"eng"}],"department":[{"_id":"HeEd"},{"_id":"GradSch"}],"alternative_title":["ISTA Thesis"],"date_updated":"2026-07-29T13:24:38Z","doi_confirm":"1","publist_id":"7712","date_published":"2018-06-11T00:00:00Z","article_processing_charge":"No","supervisor":[{"first_name":"Herbert","orcid":"0000-0002-9823-6833","full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner"}],"doi":"10.15479/AT:ISTA:th_1026","fulldoi":"https://doi.org/10.15479/AT:ISTA:th_1026","date_created":"2018-12-11T11:45:10Z","publication_status":"published","year":"2018","type":"dissertation","file_date_updated":"2020-07-14T12:45:24Z","author":[{"first_name":"Mabel","full_name":"Iglesias Ham, Mabel","id":"41B58C0C-F248-11E8-B48F-1D18A9856A87","last_name":"Iglesias Ham"}],"citation":{"mla":"Iglesias Ham, Mabel. <i>Multiple Covers with Balls</i>.

While being very convenient mathematically, it is often very clearly violated in practice. This disparity between the machine learning theory and applications underlies a growing demand in the development of algorithms that learn from dependent data and theory that can provide generalization guarantees similar to the independent situations. This thesis is dedicated to two variants of dependencies that can arise in practice. One is a dependence on the level of samples in a single learning task. Another dependency type arises in the multi-task setting when the tasks are dependent on each other even though the data for them can be i.i.d. In both cases we model the data (samples or tasks) as stochastic processes and introduce new algorithms for both settings that take into account and exploit the resulting dependencies. We prove the theoretical guarantees on the performance of the introduced algorithms under different evaluation criteria and, in addition, we compliment the theoretical study by the empirical one, where we evaluate some of the algorithms on two real world datasets to highlight their practical applicability.","lang":"eng"}],"oa_version":"Published Version","project":[{"grant_number":"308036","_id":"2532554C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Lifelong Learning of Visual Scene Understanding"}],"department":[{"_id":"ChLa"},{"_id":"GradSch"}],"alternative_title":["ISTA Thesis"],"has_accepted_license":"1","degree_awarded":"PhD","OA_place":"publisher","title":"Learning from dependent data","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","corr_author":"1","day":"01","month":"09","status":"public","article_processing_charge":"No","supervisor":[{"last_name":"Lampert","first_name":"Christoph","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","full_name":"Lampert, Christoph"}],"fulldoi":"https://doi.org/10.15479/AT:ISTA:TH1048","doi":"10.15479/AT:ISTA:TH1048","date_created":"2018-12-11T11:44:27Z","publication_status":"published","year":"2018","doi_confirm":"1","date_updated":"2026-07-29T13:31:12Z","publist_id":"7986","date_published":"2018-09-01T00:00:00Z","author":[{"full_name":"Zimin, Alexander","id":"37099E9C-F248-11E8-B48F-1D18A9856A87","first_name":"Alexander","last_name":"Zimin"}],"file_date_updated":"2020-07-14T12:47:40Z","citation":{"chicago":"Zimin, Alexander. “Learning from Dependent Data.” Institute of Science and Technology Austria, 2018. <a href=\"https://doi.org/10.15479/AT:ISTA:TH1048\">https://doi.org/10.15479/AT:ISTA:TH1048</a>.","ista":"Zimin A. 2018.

Motivated by the success of decentralized cryptocurrencies, exemplified by Bitcoin, the focus of this thesis will be on proof systems which found applications in some sustainable alternatives to Bitcoin, such as the Spacemint and Chia cryptocurrencies. In particular, we focus on proofs of space and proofs of sequential work.\r\nProofs of space (PoSpace) were suggested as more ecological, economical, and egalitarian alternative to the energy-wasteful proof-of-work mining of Bitcoin. However, the state-of-the-art constructions of PoSpace are based on sophisticated graph pebbling lower bounds, and are therefore complex. Moreover, when these PoSpace are used in cryptocurrencies like Spacemint, miners can only start mining after ensuring that a commitment to their space is already added in a special transaction to the blockchain. Proofs of sequential work (PoSW) are proof systems in which a prover, upon receiving a statement x and a time parameter T, computes a proof which convinces the verifier that T time units had passed since x was received. Whereas Spacemint assumes synchrony to retain some interesting Bitcoin dynamics, Chia requires PoSW with unique proofs, i.e., PoSW in which it is hard to come up with more than one accepting proof for any true statement. In this thesis we construct simple and practically-efficient PoSpace and PoSW. When using our PoSpace in cryptocurrencies, miners can start mining on the fly, like in Bitcoin, and unlike current constructions of PoSW, which either achieve efficient verification of sequential work, or faster-than-recomputing verification of correctness of proofs, but not both at the same time, ours achieve the best of these two worlds."}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"publist_id":"7971","doi_confirm":"1","date_updated":"2026-07-29T13:38:08Z","date_published":"2018-09-05T00:00:00Z","fulldoi":"https://doi.org/10.15479/AT:ISTA:TH_1046","doi":"10.15479/AT:ISTA:TH_1046","article_processing_charge":"No","supervisor":[{"first_name":"Krzysztof Z","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak"}],"year":"2018","date_created":"2018-12-11T11:44:32Z","publication_status":"published","type":"dissertation","citation":{"chicago":"Abusalah, Hamza M. “Proof Systems for Sustainable Decentralized Cryptocurrencies.” Institute of Science and Technology Austria, 2018. <a href=\"https://doi.org/10.15479/AT:ISTA:TH_1046\">https://doi.org/10.15479/AT:ISTA:TH_1046</a>.","apa":"Abusalah, H.

Under normal range of\r\nprecipitation variability, wet years typically result in ANPP gains being\r\nlarger than ANPP declines in dry years (positive asymmetry), whereas\r\nincreases in ANPP are lower in magnitude in extreme wet years compared to\r\nreductions during extreme drought (negative asymmetry). Whether the current\r\ngeneration of ecosystem models with a coupled carbon–water system in\r\ngrasslands are capable of simulating these asymmetric ANPP responses is an\r\nunresolved question. In this study, we evaluated the simulated responses of\r\ntemperate grassland primary productivity to scenarios of altered\r\nprecipitation with 14 ecosystem models at three sites: Shortgrass\r\nsteppe (SGS), Konza Prairie (KNZ) and Stubai Valley meadow (STU), spanning a\r\nrainfall gradient from dry to moist. We found that (1) the spatial slopes\r\nderived from modeled primary productivity and precipitation across sites were\r\nsteeper than the temporal slopes obtained from inter-annual variations, which\r\nwas consistent with empirical data; (2) the asymmetry of the responses of\r\nmodeled primary productivity under normal inter-annual precipitation\r\nvariability differed among models, and the mean of the model ensemble\r\nsuggested a negative asymmetry across the three sites, which was contrary to\r\nempirical evidence based on filed observations; (3) the mean sensitivity of\r\nmodeled productivity to rainfall suggested greater negative response with\r\nreduced precipitation than positive response to an increased precipitation\r\nunder extreme conditions at the three sites; and (4) gross primary productivity\r\n(GPP), net primary productivity (NPP), aboveground NPP (ANPP) and belowground\r\nNPP (BNPP) all showed concave-down nonlinear responses to altered\r\nprecipitation in all the models, but with different curvatures and mean\r\nvalues.

Understanding their variability in space and time sheds light on the link between discharge formation and water quality at the catchment scale. Here, we introduce a novel modeling framework to explore water transport mechanisms using the Hafren catchment in Wales (UK) as a case study. We show that a fully distributed hydrological model coupled with a transport component for conservative tracers is useful in analyzing how hydrometeorological conditions and spatial heterogeneity may affect water transit times and age distributions in a real catchment. We use the model to track the paths of water parcels that entered the catchment as rainfall over 2 years, labeling each day of rain individually. There is a reasonable agreement between tracer simulations and observations, suggesting that dynamic transit time distributions (TTDs) both forward and backward in time can be approximated using a high spatial and temporal resolution hydrochemical model, without assuming a priori any transit and storage selection functions at the catchment scale. TTDs are quantified for the modeled internal dynamics of the study catchment. TTDs conditional on a given rainfall time are mostly correlated to the season in which the rain event occurs, whereas TTDs conditional on a given exit time are mostly affected by catchment wetness. When TTDs for individual rainfall events are re‐scaled as functions of cumulative discharge, they collapse around a single common distribution, suggesting a potential characteristic catchment function.","lang":"eng"}],"_id":"22481","OA_place":"publisher","extern":"1","OA_type":"free access","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Water flux tracking with a distributed hydrological model to quantify controls on the spatio-temporal variability of transit time distributions","status":"public","month":"04","day":"01"},{"author":[{"full_name":"Manoli, Gabriele","first_name":"Gabriele","last_name":"Manoli"},{"full_name":"Ivanov, Valeriy Y.","first_name":"Valeriy Y.","last_name":"Ivanov"},{"full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","first_name":"Simone","last_name":"Fatichi"}],"citation":{"chicago":"Manoli, Gabriele, Valeriy Y.

Even though water stress should suppress photosynthesis and enhance tree mortality, a green‐up has been often observed during the dry season. This interplay between climatic forcing and forest phenology is poorly understood and inadequately represented in most of existing dynamic global vegetation models calling for an improved description of the Amazon seasonal dynamics. Recent findings on tropical leaf phenology are incorporated in the state‐of‐the‐art eco‐hydrological model Thetys &amp; Chloris. The new model accounts for a mechanistic light‐controlled leaf development, synchronized dry‐season litterfall, and an age‐dependent leaf photosynthetic capacity. Simulation results from 32 sites in the Amazon basin over a 15‐year period successfully mimic the seasonality of gross primary productivity; evapotranspiration (ET); as well as leaf area index, leaf age, and leaf productivity. Representation of tropical leaf phenology reproduces the observed dry‐season greening, reduces simulated gross primary productivity, and does not alter ET, when compared with simulations without phenology. Tolerance to dry periods, with the exception of major drought events, is simulated by the model. Deep roots rather than leaf area index regulation mechanisms control the response to short‐term droughts, but legacy effects can exacerbate multiyear water stress. Our results provide a novel mechanistic approach to model leaf phenology and flux seasonality in the tropics, reconciling the generally observed dry‐season greening, ET seasonality, and decreased carbon uptake during severe droughts."}],"oa_version":"Published Version","day":"01","month":"06","status":"public","OA_type":"free access","OA_place":"publisher","extern":"1","title":"Dry‐season greening and water stress in Amazonia: The role of modeling leaf phenology","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","date_created":"2026-07-27T12:30:23Z","publication_status":"published","year":"2018","article_processing_charge":"No","scopus_import":"1","fulldoi":"https://doi.org/10.1029/2017jg004282","doi":"10.1029/2017jg004282","date_published":"2018-06-01T00:00:00Z","publication":"Journal of Geophysical Research: Biogeosciences","quality_controlled":"1","date_updated":"2026-07-30T06:04:25Z","intvolume":"       123"},{"year":"2018","publication_status":"published","date_created":"2018-12-11T11:44:21Z","fulldoi":"https://doi.org/10.15479/AT:ISTA:th_1033","doi":"10.15479/AT:ISTA:th_1033","supervisor":[{"last_name":"Katsaros","first_name":"Georgios","orcid":"0000-0001-8342-202X","full_name":"Katsaros, Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","date_published":"2018-07-30T00:00:00Z","publist_id":"8005","doi_confirm":"1","date_updated":"2026-07-31T09:15:25Z","alternative_title":["ISTA Thesis"],"department":[{"_id":"GeKa"},{"_id":"GradSch"}],"_id":"49","abstract":[{"text":"Nowadays, quantum computation is receiving more and more attention as an alternative to the classical way of computing. For realizing a quantum computer, different devices are investigated as potential quantum bits. In this thesis, the focus is on Ge hut wires, which turned out to be promising candidates for implementing hole spin quantum bits. The advantages of Ge as a material system are the low hyperfine interaction for holes and the strong spin orbit coupling, as well as the compatibility with the highly developed CMOS processes in industry. In addition, Ge can also be isotopically purified which is expected to boost the spin coherence times. The strong spin orbit interaction for holes in Ge on the one hand enables the full electrical control of the quantum bit and on the other hand should allow short spin manipulation times. Starting with a bare Si wafer, this work covers the entire process reaching from growth over the fabrication and characterization of hut wire devices up to the demonstration of hole spin resonance. From experiments with single quantum dots, a large g-factor anisotropy between the in-plane and the out-of-plane direction was found. A comparison to a theoretical model unveiled the heavy-hole character of the lowest energy states. The second part of the thesis addresses double quantum dot devices, which were realized by adding two gate electrodes to a hut wire. In such devices, Pauli spin blockade was observed, which can serve as a read-out mechanism for spin quantum bits. Applying oscillating electric fields in spin blockade allowed the demonstration of continuous spin rotations and the extraction of a lower bound for the spin dephasing time. Despite the strong spin orbit coupling in Ge, the obtained value for the dephasing time is comparable to what has been recently reported for holes in Si. All in all, the presented results point out the high potential of Ge hut wires as a platform for long-lived, fast and fully electrically tunable hole spin quantum bits.","lang":"eng"}],"oa_version":"Published Version","day":"30","month":"07","status":"public","corr_author":"1","title":"Ge hut wires - from growth to hole spin resonance","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","degree_awarded":"PhD","OA_place":"publisher","has_accepted_license":"1","file":[{"relation":"main_file","checksum":"b653b5216251f938ddbeafd1de88667c","date_created":"2019-04-09T07:13:28Z","access_level":"open_access","content_type":"application/pdf","date_updated":"2020-07-14T12:46:35Z","file_name":"2018_Thesis_Watzinger.pdf","file_size":85539748,"file_id":"6249","creator":"dernst"},{"content_type":"application/zip","access_level":"closed","date_created":"2019-04-09T07:13:27Z","relation":"source_file","checksum":"39bcf8de7ac5b1bb516b11ce2f966785","creator":"dernst","file_id":"6250","file_name":"2018_Thesis_Watzinger_source.zip","date_updated":"2020-07-14T12:46:35Z","file_size":21830697}],"publication_identifier":{"issn":["2663-337X"]},"oa":1,"language":[{"iso":"eng"}],"page":"77","publisher":"Institute of Science and Technology Austria","pubrep_id":"1033","ddc":["530"],"citation":{"ama":"Watzinger H.

However, while OP-induced carbon emissions and biodiversity losses have received significant attention, OP water requirements have been marginalized and little is known on the ecohydrological changes (water and surface energy fluxes) occurring from forest clearing to plantation maturity. Numerical simulations supported by field observations from seven sites in Southeast Asia (five OP plantations and two tropical forests) are used here to illustrate the temporal evolution of OP actual evapotranspiration (ET), infiltration/runoff, gross primary productivity (GPP) and surface temperature as well as their changes relative to tropical forests. Model results from large-scale commercial plantations show that young OP plantations decrease ecosystem ET, causing hotter and drier climatic conditions, but mature plantations (age > 8−9 yr) have higher GPP and transpire more water (up to +7.7%) than the forests they have replaced. This is the result of physiological constraints on water use efficiency and the extremely high yield of OP (six to ten times higher than other oil crops). Hence, the land use efficiency of mature OP, i.e. the high productivity per unit of land area, comes at the expense of water consumption in a trade of water for carbon that may jeopardize local water resources. Sequential replanting and herbaceous ground cover can reduce the severity of such ecohydrological changes and support local water/climate regulation.","lang":"eng"}]},{"quality_controlled":"1","date_updated":"2026-08-06T07:46:04Z","intvolume":"        13","date_published":"2018-10-05T00:00:00Z","publication":"Environmental Research Letters","article_processing_charge":"No","scopus_import":"1","doi":"10.1088/1748-9326/aae267","fulldoi":"https://doi.org/10.1088/1748-9326/aae267","publication_status":"published","article_type":"letter_note","date_created":"2026-07-27T12:30:24Z","year":"2018","extern":"1","OA_place":"publisher","OA_type":"gold","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Covariation of vegetation and climate constrains present and future T/ET variability","keyword":["T/ET","Evapotranspiration partitioning","Ecohydrology","Modelling","Climate change"],"status":"public","day":"05","month":"10","oa_version":"Published Version","abstract":[{"lang":"eng","text":"The reliable partitioning of the terrestrial latent heat flux into evaporation (E) and transpiration (T) is important for linking carbon and water cycles and for better understanding ecosystem functioning at local, regional and global scales. Previous research revealed that the transpiration-to-evapotranspiration ratio (T/ET) is well constrained across ecosystems and is nearly independent of vegetation characteristics and climate. Here we investigated the reasons for such a global constancy in present-day T/ET by jointly analysing observations and process-based model simulations. Using this framework, we also quantified how the ratio T/ET could be influenced by changing climate. For present conditions, we found that the various components of land surface evaporation (bare soil evaporation, below canopy soil evaporation, evaporation from interception), and their respective ratios to plant transpiration, depend largely on local climate and equilibrium vegetation properties. The systematic covariation between local vegetation characteristics and climate, resulted in a globally constrained value of T/ET = ∼70 ± 9% for undisturbed ecosystems, nearly independent of specific climate and vegetation attributes. Moreover, changes in precipitation amounts and patterns, increasing air temperatures, atmospheric CO2 concentration, and specific leaf area (the ratio of leaf area per leaf mass) was found to affect T/ET in various manners. However, even extreme changes in the aforementioned factors did not significantly modify T/ET."}],"_id":"22540","ddc":["550"],"publisher":"IOP Publishing ","language":[{"iso":"eng"}],"oa":1,"volume":13,"publication_identifier":{"eissn":["1748-9326"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1088/1748-9326/aae267"}],"article_number":"104012","das_tickbox":"1","issue":"10","type":"journal_article","author":[{"last_name":"Paschalis","full_name":"Paschalis, Athanasios","first_name":"Athanasios"},{"last_name":"Fatichi","full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","first_name":"Simone"},{"first_name":"Christoforos","full_name":"Pappas, Christoforos","last_name":"Pappas"},{"first_name":"Dani","full_name":"Or, Dani","last_name":"Or"}],"DOAJ_listed":"1","citation":{"ama":"Paschalis A, Fatichi S, Pappas C, Or D.

These instruments measure rainfall at different spatial scales: rain-gauge samples rainfall at the point scale while weather radar averages precipitation on a relatively large area, generally around 1 km2. As such, a radar derived IDF curve is representative of the mean areal rainfall over a given radar pixel and neglects the within-pixel rainfall variability. In this study, we quantify subpixel variability of extreme rainfall by using a novel space–time rainfall generator (STREAP model) that downscales in space the rainfall within a given radar pixel. The study was conducted using a unique radar data record (23 years) and a very dense rain-gauge network in the Eastern Mediterranean area (northern Israel). Radar–IDF curves, together with an ensemble of point-based IDF curves representing the radar subpixel extreme rainfall variability, were developed fitting Generalized Extreme Value (GEV) distributions to annual rainfall maxima. It was found that the mean areal extreme rainfall derived from the radar underestimate most of the extreme values computed for point locations within the radar pixel (on average, ∼70%). The subpixel variability of rainfall extreme was found to increase with longer return periods and shorter durations (e.g. from a maximum variability of 10% for a return period of 2 years and a duration of 4 h to 30% for 50 years return period and 20 min duration). For the longer return periods, a considerable enhancement of extreme rainfall variability was found when stochastic (natural) climate variability was taken into account. Bounding the range of the subpixel extreme rainfall derived from radar–IDF can be of major importance for different applications that require very local estimates of rainfall extremes."}],"_id":"22550","quality_controlled":"1","date_updated":"2026-08-06T08:09:51Z","intvolume":"       556","date_published":"2018-01-01T00:00:00Z","publication":"Journal of Hydrology","scopus_import":"1","article_processing_charge":"No","doi":"10.1016/j.jhydrol.2016.05.033","fulldoi":"https://doi.org/10.1016/j.jhydrol.2016.05.033","date_created":"2026-07-27T12:30:24Z","article_type":"original","publication_status":"published","year":"2018"},{"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"citation":{"ama":"Hross S, Theis FJ, Sixt MK, Hasenauer J.

Imaging data provide quantitative information about biological systems; however, mechanisms causing spatial patterning often remain elusive. In recent years, spatio-temporal mathematical modelling has helped to overcome this problem. Yet, outliers and structured noise limit modelling of whole imaging data, and models often consider spatial summary statistics. Here, we introduce an integrated data-driven modelling approach that can cope with measurement artefacts and whole imaging data. Our approach combines mechanistic models of the biological processes with robust statistical models of the measurement process. The parameters of the integrated model are calibrated using a maximum-likelihood approach. We used this integrated modelling approach to study in vivo gradients of the chemokine (C-C motif) ligand 21 (CCL21). CCL21 gradients guide dendritic cells and are important in the adaptive immune response. Using artificial data, we verified that the integrated modelling approach provides reliable parameter estimates in the presence of measurement noise and that bias and variance of these estimates are reduced compared to conventional approaches. The application to experimental data allowed the parametrization and subsequent refinement of the model using additional mechanisms. Among other results, model-based hypothesis testing predicted lymphatic vessel-dependent concentration of heparan sulfate, the binding partner of CCL21. The selected model provided an accurate description of the experimental data and was partially validated using published data. Our findings demonstrate that integrated statistical modelling of whole imaging data is computationally feasible and can provide novel biological insights.","lang":"eng"}],"_id":"5858","oa_version":"Published Version","external_id":{"isi":["000456783800011"]},"title":"Mechanistic description of spatial processes using integrative modelling of noise-corrupted imaging data","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","has_accepted_license":"1","month":"12","day":"05","isi":1,"status":"public","fulldoi":"https://doi.org/10.1098/rsif.2018.0600","doi":"10.1098/rsif.2018.0600","scopus_import":"1","article_processing_charge":"No","year":"2018","publication_status":"published","date_created":"2019-01-20T22:59:18Z","intvolume":"        15","date_updated":"2026-08-12T06:28:50Z","quality_controlled":"1","publication":"Journal of the Royal Society Interface","date_published":"2018-12-05T00:00:00Z"},{"date_published":"2018-12-12T00:00:00Z","publication":"Journal of the Royal Society Interface","quality_controlled":"1","date_updated":"2026-08-12T06:28:34Z","intvolume":"        15","date_created":"2019-01-20T22:59:19Z","publication_status":"published","year":"2018","article_processing_charge":"No","scopus_import":"1","fulldoi":"https://doi.org/10.1098/rsif.2018.0395","doi":"10.1098/rsif.2018.0395","month":"12","day":"12","status":"public","isi":1,"title":"Zipf's Law, unbounded complexity and open-ended evolution","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["1612.01605"],"isi":["000456783800002"]},"abstract":[{"text":"A major problem for evolutionary theory is understanding the so-called open-ended nature of evolutionary change, from its definition to its origins. Open-ended evolution (OEE) refers to the unbounded increase in complexity that seems to characterize evolution on multiple scales. This property seems to be a characteristic feature of biological and technological evolution and is strongly tied to the generative potential associated with combinatorics, which allows the system to grow and expand their available state spaces. Interestingly, many complex systems presumably displaying OEE, from language to proteins, share a common statistical property: the presence of Zipf's Law. Given an inventory of basic items (such as words or protein domains) required to build more complex structures (sentences or proteins) Zipf's Law tells us that most of these elements are rare whereas a few of them are extremely common. Using algorithmic information theory, in this paper we provide a fundamental definition for open-endedness, which can be understood as postulates. Its statistical counterpart, based on standard Shannon information theory, has the structure of a variational problem which is shown to lead to Zipf's Law as the expected consequence of an evolutionary process displaying OEE. We further explore the problem of information conservation through an OEE process and we conclude that statistical information (standard Shannon information) is not conserved, resulting in the paradoxical situation in which the increase of information content has the effect of erasing itself. We prove that this paradox is solved if we consider non-statistical forms of information. This last result implies that standard information theory may not be a suitable theoretical framework to explore the persistence and increase of the information content in OEE systems.","lang":"eng"}],"_id":"5860","oa_version":"Preprint","department":[{"_id":"EdHa"}],"arxiv":1,"oa":1,"language":[{"iso":"eng"}],"publisher":"Royal Society","volume":15,"publication_identifier":{"issn":["1742-5689"]},"article_number":"20180395","main_file_link":[{"url":"https://arxiv.org/abs/1612.01605","open_access":"1"}],"issue":"149","type":"journal_article","author":[{"first_name":"Bernat","id":"43BE2298-F248-11E8-B48F-1D18A9856A87","full_name":"Corominas-Murtra, Bernat","orcid":"0000-0001-9806-5643","last_name":"Corominas-Murtra"},{"first_name":"Luís F.","full_name":"Seoane, Luís F.","last_name":"Seoane"},{"first_name":"Ricard","full_name":"Solé, Ricard","last_name":"Solé"}],"citation":{"mla":"Corominas-Murtra, Bernat, et al. “Zipf’s Law, Unbounded Complexity and Open-Ended Evolution.” <i>Journal of the Royal Society Interface</i>, vol. 15, no. 149, 20180395, Royal Society, 2018, doi:<a href=\"https://doi.org/10.1098/rsif.2018.0395\">10.1098/rsif.2018.0395</a>.","ista":"Corominas-Murtra B, Seoane LF, Solé R. 2018.
