To understand these, we construct three sets of machine learning potentials that are simultaneously applicable to various TiO2 surfaces, based on three density-functional-theory approximations. Here we show the water dissociation free energies on seven pristine TiO2 surfaces, and predict that anatase (100), anatase (110), rutile (001), and rutile (011) favor water dissociation, anatase (101) and rutile (100) have mostly molecular adsorption, while the simulations of rutile (110) sensitively depend on the slab thickness and molecular adsorption is preferred with thick slabs. Moreover, using an automated algorithm, we reveal that these surfaces follow different types of atomistic mechanisms for proton transfer and water dissociation: one-step, two-step, or both. These mechanisms can be rationalized based on the arrangements of water molecules on the different surfaces. Our finding thus demonstrates that the different pristine TiO2 surfaces react with water in distinct ways, and cannot be represented using just the low-energy anatase (101) and rutile (110) surfaces.","lang":"eng"}],"title":"Mechanistic insight on water dissociation on pristine low-index TiO2 surfaces from machine learning molecular dynamics simulations","acknowledgement":"F.S., J.H., and B.C. thank the Swiss National Supercomputing Centre (CSCS) for the generous allocation of CPU hours via production project s1108 at the Piz Daint supercomputer.

This paper introduces a molecular-dynamics workflow that simplifies and robustly computes the solubility of molecular or ionic crystals. This method is considerably more straightforward than the state-of-the-art, as we have streamlined and optimised each step of the process. Specifically, we calculate the chemical potential of the crystal using the gas-phase molecule as a reference state, and employ the S0 method to determine the concentration dependence of the chemical potential of the solute. We use this workflow to predict the solubilities of sodium chloride in water, urea polymorphs in water, and paracetamol polymorphs in both water and ethanol. Our findings indicate that the predicted solubility is sensitive to the chosen potential energy surface. Furthermore, we note that the harmonic approximation often fails for both molecular crystals and gas molecules at or above room temperature, and that the assumption of an ideal solution becomes less valid for highly soluble substances.","lang":"eng"}],"title":"A streamlined molecular-dynamics workflow for computing solubilities of molecular and ionic crystals","acknowledgement":"A.R. and B.C. acknowledge resources provided by the Cambridge Tier-2 system operated by the University of Cambridge Research Computing Service funded by EPSRC Tier-2 capital Grant No. EP/P020259/1.

A separate treatment of these contributions, where only the free-free part follows the Mermin dispersion, shows good agreement with LR-TDDFT results for ambient-density beryllium, but breaks down for highly compressed matter where the bound states become pressure ionized.

Herein, we study the lattice dynamics and thermal property of AgX under the framework of perturbation theory and the two-channel Wigner thermal transport model based on accurate machine learning potentials. We find that an accurate extraction of the third-order atomic force constants from largely displaced configurations is significant for the calculation of the κL of AgX, and the coherence thermal transport is also non-negligible. In AgI, however, the calculated κL still considerably overestimates the experimental values even including four-phonon scatterings. Molecular dynamics (MD) simulations using machine learning potential suggest an important role of the higher-than-fourth-order lattice anharmonicity in the low-frequency phonon linewidths of AgI at room temperature, which can be related to the simultaneous restrictions of the three- and four-phonon phase spaces. The κL of AgI calculated using MD phonon lifetimes including full-order lattice anharmonicity shows a better agreement with experiments.","lang":"eng"}],"quality_controlled":"1","project":[{"name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","call_identifier":"H2020"}],"publisher":"American Physical Society","status":"public","issue":"17","doi":"10.1103/PhysRevB.108.174302","publication_status":"published","citation":{"mla":"Ouyang, Niuchang, et al. “Role of High-Order Lattice Anharmonicity in the Phonon Thermal Transport of Silver Halide AgX (X=Cl,Br, I).” <i>Physical Review B</i>, vol. 108, no. 17, 174302, American Physical Society, 2023, doi:<a href=\"https://doi.org/10.1103/PhysRevB.108.174302\">10.1103/PhysRevB.108.174302</a>.","ama":"Ouyang N, Zeng Z, Wang C, Wang Q, Chen Y.

One prominent example is single-atom alloys, where the reactive dopant atoms can preferentially locate in the bulk or at different sites on the surface of the nanoparticle. However, ab initio modeling of catalysts usually only considers one site of the catalyst, neglecting the effects of multiple sites. Here, nanoparticles of copper doped with single-atom rhodium or palladium are modeled for the dehydrogenation of propane. Single-atom alloy nanoparticles are simulated at 400–600 K, using machine learning potentials trained on density functional theory calculations, and then the occupation of different single-atom active sites is identified using a similarity kernel. Further, the turnover frequency for all possible sites is calculated for propane dehydrogenation to propene through microkinetic modeling using density functional theory calculations. The total turnover frequencies of the whole nanoparticle are then described from both the population and the individual turnover frequency of each site. Under operating conditions, rhodium as a dopant is found to almost exclusively occupy (111) surface sites while palladium as a dopant occupies a greater variety of facets. Undercoordinated dopant surface sites are found to tend to be more reactive for propane dehydrogenation compared to the (111) surface. It is found that considering the dynamics of the single-atom alloy nanoparticle has a profound effect on the calculated catalytic activity of single-atom alloys by several orders of magnitude.","lang":"eng"}],"publication_status":"published","citation":{"ieee":"R.

This behaviour potentially plays a role in explaining the origin of the multipolar magnetic fields of Uranus and Neptune, whose mantles are thought to result from a mixture of H2O, NH3 and CH4 ices. Determining the stability domain, melting curve and electrical conductivity of these superionic phases is therefore crucial for modelling planetary interiors and dynamos. Here we report the melting curve of superionic ammonia up to 300 GPa from laser-driven shock compression of pre-compressed samples and atomistic calculations. We show that ammonia melts at lower temperatures than water above 100 GPa and that fluid ammonia’s electrical conductivity exceeds that of water at conditions predicted by hot, super-adiabatic models for Uranus and Neptune, and enhances the conductivity in their fluid water-rich dynamo layers."}],"acknowledgement":"We acknowledge the crucial contribution of the LULI2000 laser and support teams to the success of the experiments.

The HSE functional offers not only a more accurate description of the electronic band gap but also shifts the onset of molecular dissociation in the molecular dynamics simulations to significantly higher pressures. We also highlight the importance of using accurate reference standards in reflectivity experiments and reanalyze infrared and optical reflectivity data from recent experiments.

Mechanistic modeling approaches incorporating cryospheric, hydrological, and vegetation processes in high spatial, temporal, and physical detail have never been applied for high-elevation catchments of HMA. We use a land surface model at high spatial and temporal resolution (100 m and hourly) to simulate the coupled dynamics of energy, water, and vegetation for the 350 km2 Langtang catchment (Nepal). We compare our model outputs for one hydrological year against a large set of observations to gain insight into the partitioning of the water balance at the subseasonal scale and across elevation bands. During the simulated hydrological year, we find that evapotranspiration is a key component of the total water balance, as it causes about the equivalent of 20% of all the available precipitation or 154% of the water production from glacier melt in the basin to return directly to the atmosphere. The depletion of the cryospheric water budget is dominated by snow melt, but at high elevations is primarily dictated by snow and ice sublimation. Snow sublimation is the dominant vapor flux (49%) at the catchment scale, accounting for the equivalent of 11% of snowfall, 17% of snowmelt, and 75% of ice melt, respectively. We conclude that simulations should consider sublimation and other evaporative fluxes explicitly, as otherwise water balance estimates can be ill-quantified."}],"title":"Land surface modeling in the himalayas: on the importance of evaporative fluxes for the water balance of a high‐elevation catchment"},{"day":"01","article_processing_charge":"Yes","type":"journal_article","corr_author":"1","page":"8651-8662","author":[{"last_name":"Neiheiser","orcid":"0000-0001-7227-8309","full_name":"Neiheiser, Ray","id":"f09651b9-fec0-11ec-b5d8-934aff0e52a4","first_name":"Ray"},{"first_name":"Gustavo","full_name":"Inacio, Gustavo","last_name":"Inacio"},{"last_name":"Rech","first_name":"Luciana","full_name":"Rech, Luciana"},{"first_name":"Carlos","full_name":"Montez, Carlos","last_name":"Montez"},{"full_name":"Matos, Miguel","first_name":"Miguel","last_name":"Matos"},{"full_name":"Rodrigues, Luis","first_name":"Luis","last_name":"Rodrigues"}],"publication_identifier":{"issn":["2169-3536"]},"scopus_import":"1","external_id":{"isi":["000927831000001"]},"date_published":"2023-08-01T00:00:00Z","language":[{"iso":"eng"}],"keyword":["General Engineering","General Materials Science","General Computer Science","Electrical and Electronic Engineering"],"fulldoi":"https://doi.org/10.1109/access.2023.3237897","ddc":["000"],"has_accepted_license":"1","publisher":"IEEE","status":"public","quality_controlled":"1","title":"Practical limitations of Ethereum’s layer-2","abstract":[{"lang":"eng","text":"Most permissionless blockchains inherently suffer from throughput limitations. Layer-2 systems, such as side-chains or Rollups, have been proposed as a possible strategy to overcome this limitation. Layer-2 systems interact with the main-chain in two ways. First, users can move funds from/to the main-chain to/from the layer-2. Second, layer-2 systems periodically synchronize with the main-chain to keep some form of log of their activity on the main-chain - this log is key for security. Due to this interaction with the main-chain, which is necessary and recurrent, layer-2 systems impose some load on the main-chain. The impact of such load on the main-chain has been, so far, poorly understood. In addition to that, layer-2 approaches typically sacrifice decentralization and security in favor of higher throughput. This paper presents an experimental study that analyzes the current state of Ethereum layer-2 projects. Our goal is to assess the load they impose on Ethereum and to understand their scalability potential in the long-run. Our analysis shows that the impact of any given layer-2 on the main-chain is the result of both technical aspects (how state is logged on the main-chain) and user behavior (how often users decide to transfer funds between the layer-2 and the main-chain). Based on our observations, we infer that without efficient mechanisms that allow users to transfer funds in a secure and fast manner directly from one layer-2 project to another, current layer-2 systems will not be able to scale Ethereum effectively, regardless of their technical solutions. Furthermore, from our results, we conclude that the layer-2 systems that offer similar security guarantees as Ethereum have limited scalability potential, while approaches that offer better performance, sacrifice security and lead to an increase in centralization which runs against the end-goals of permissionless blockchains."}],"acknowledgement":"This work was supported in part by the Coordenação de Aperfeiçoamento de Pessoal de Nivel Superior (CAPES)—Brazil (CAPES), in part by the Fundação para a Ciência e Tecnologia (FCT) under Project UIDB/50021/2020 and Grant 2020.05270.BD, in part by the Project COSMOS (via the Orçamento de Estado (OE) with ref.

At the same time, the massive sizes of modern deep learning models have made their deployment to smaller devices more challenging; this is particularly important, as in many applications the users rely on accurate deep learning predictions, but they only have access to devices with limited memory and compute power. One solution to this problem is to prune neural networks, by setting as many of their parameters as possible to zero, to obtain accurate sparse models with lower memory footprint. Despite the great research progress in obtaining sparse models that preserve accuracy, while satisfying memory and computational constraints, there are still many challenges associated with efficiently training sparse models, as well as understanding their generalization properties.\r\n\r\nThe focus of this thesis is to investigate how the training process of sparse models can be made more efficient, and to understand the differences between sparse and dense models in terms of how well they can generalize to changes in the data distribution. We first study a method for co-training sparse and dense models, at a lower cost compared to regular training. With our method we can obtain very accurate sparse networks, and dense models that can recover the baseline accuracy. Furthermore, we are able to more easily analyze the differences, at prediction level, between the sparse-dense model pairs. Next, we investigate the generalization properties of sparse neural networks in more detail, by studying how well different sparse models trained on a larger task can adapt to smaller, more specialized tasks, in a transfer learning scenario. Our analysis across multiple pruning methods and sparsity levels reveals that sparse models provide features that can transfer similarly to or better than the dense baseline. However, the choice of the pruning method plays an important role, and can influence the results when the features are fixed (linear finetuning), or when they are allowed to adapt to the new task (full finetuning). Using sparse models with fixed masks for finetuning on new tasks has an important practical advantage, as it enables training neural networks on smaller devices. However, one drawback of current pruning methods is that the entire training cycle has to be repeated to obtain the initial sparse model, for every sparsity target; in consequence, the entire training process is costly and also multiple models need to be stored. In the last part of the thesis we propose a method that can train accurate dense models that are compressible in a single step, to multiple sparsity levels, without additional finetuning. Our method results in sparse models that can be competitive with existing pruning methods, and which can also successfully generalize to new tasks."}],"title":"Efficiency and generalization of sparse neural networks","citation":{"ama":"Krumes A.

The multi-layer structure models inference from deep generative priors, and the rotational invariance imposed on the weights generalizes the i.i.d. Gaussian assumption by allowing for a complex correlation structure, which is typical in applications. In this work, we present a new class of approximate message passing (AMP) algorithms and give a state evolution recursion which precisely characterizes their performance in the large system limit. In contrast with the existing multi-layer VAMP (ML-VAMP) approach, our proposed AMP – dubbed multilayer rotationally invariant generalized AMP (ML-RI-GAMP) – provides a natural generalization beyond Gaussian designs, in the sense that it recovers the existing Gaussian AMP as a special case. Furthermore, ML-RI-GAMP exhibits a significantly lower complexity than ML-VAMP, as the computationally intensive singular value decomposition is replaced by an estimation of the moments of the design matrices. Finally, our numerical results show that this complexity gain comes at little to no cost in the performance of the algorithm."}],"quality_controlled":"1","status":"public","publisher":"IEEE","project":[{"_id":"059876FA-7A3F-11EA-A408-12923DDC885E","name":"Prix Lopez-Loretta 2019 - Marco Mondelli"}],"fulldoi":"https://doi.org/10.1109/ITW55543.2023.10160238","language":[{"iso":"eng"}],"external_id":{"arxiv":["2212.01572"],"isi":["001031733100053"]},"date_published":"2023-05-01T00:00:00Z","arxiv":1,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2212.01572","open_access":"1"}],"publication_identifier":{"isbn":["9798350301496"],"eissn":["2475-4218"]},"scopus_import":"1","author":[{"last_name":"Xu","first_name":"Yizhou","full_name":"Xu, Yizhou"},{"last_name":"Hou","first_name":"Tian Qi","full_name":"Hou, Tian Qi"},{"last_name":"Liang","first_name":"Shan Suo","full_name":"Liang, Shan Suo"},{"first_name":"Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020","last_name":"Mondelli"}],"corr_author":"1","page":"294-298","type":"conference","article_processing_charge":"No","day":"01"},{"external_id":{"isi":["000936534100012"],"arxiv":["2204.07373"]},"date_published":"2023-03-01T00:00:00Z","arxiv":1,"language":[{"iso":"eng"}],"has_accepted_license":"1","ddc":["000"],"fulldoi":"https://doi.org/10.1109/LRA.2023.3240930","day":"01","type":"journal_article","article_processing_charge":"No","page":"1595-1602","scopus_import":"1","publication_identifier":{"eissn":["2377-3766"]},"author":[{"last_name":"Lechner","id":"3DC22916-F248-11E8-B48F-1D18A9856A87","first_name":"Mathias","full_name":"Lechner, Mathias"},{"last_name":"Amini","first_name":"Alexander","full_name":"Amini, Alexander"},{"first_name":"Daniela","full_name":"Rus, Daniela","last_name":"Rus"},{"last_name":"Henzinger","orcid":"0000-0002-2985-7724","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"}],"oa_version":"Published Version","publication":"IEEE Robotics and Automation Letters","file_date_updated":"2023-03-07T12:22:23Z","intvolume":"         8","related_material":{"record":[{"relation":"earlier_version","id":"11366","status":"public"}]},"isi":1,"file":[{"file_size":944052,"checksum":"5a75dcd326ea66685de2b1aaec259e85","relation":"main_file","access_level":"open_access","date_created":"2023-03-07T12:22:23Z","content_type":"application/pdf","success":1,"file_id":"12714","date_updated":"2023-03-07T12:22:23Z","creator":"cchlebak","file_name":"2023_IEEERobAutLetters_Lechner.pdf"}],"date_updated":"2026-08-12T06:40:15Z","oa":1,"date_created":"2023-03-05T23:01:04Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"ToHe"}],"article_type":"original","_id":"12704","month":"03","quality_controlled":"1","issue":"3","status":"public","publisher":"IEEE","acknowledgement":"We thank Christoph Lampert for inspiring this work.

However, the improved robustness does not come for free but rather is accompanied by a decrease in overall model accuracy and performance. Recent work has shown that, in practical robot learning applications, the effects of adversarial training do not pose a fair trade-off but inflict a net loss when measured in holistic robot performance. This work revisits the robustness-accuracy trade-off in robot learning by systematically analyzing if recent advances in robust training methods and theory in conjunction with adversarial robot learning, are capable of making adversarial training suitable for real-world robot applications. We evaluate three different robot learning tasks ranging from autonomous driving in a high-fidelity environment amenable to sim-to-real deployment to mobile robot navigation and gesture recognition. Our results demonstrate that, while these techniques make incremental improvements on the trade-off on a relative scale, the negative impact on the nominal accuracy caused by adversarial training still outweighs the improved robustness by an order of magnitude. We conclude that although progress is happening, further advances in robust learning methods are necessary before they can benefit robot learning tasks in practice."}],"title":"Revisiting the adversarial robustness-accuracy tradeoff in robot learning","publication_status":"published","citation":{"mla":"Lechner, Mathias, et al. “Revisiting the Adversarial Robustness-Accuracy Tradeoff in Robot Learning.” <i>IEEE Robotics and Automation Letters</i>, vol. 8, no. 3, IEEE, 2023, pp. 1595–602, doi:<a href=\"https://doi.org/10.1109/LRA.2023.3240930\">10.1109/LRA.2023.3240930</a>.","ama":"Lechner M, Amini A, Rus D, Henzinger TA.

Due to its good practical performance, this approximative approach is typically preferred over exact techniques, even though no practical bounds on the imprecision of the result could be given until recently. As a consequence, even the most used model checkers could return arbitrarily wrong results. Over the past decade, different works derived stopping criteria, indicating when the precision reaches the desired level, for various settings, in particular MDP with reachability, total reward, and mean payoff, and SG with reachability.In this paper, we provide the first stopping criteria for VI on SG with total reward and mean payoff, yielding the first anytime algorithms in these settings. To this end, we provide the solution in two flavours: First through a reduction to the MDP case and second directly on SG. The former is simpler and automatically utilizes any advances on MDP. The latter allows for more local computations, heading towards better practical efficiency.Our solution unifies the previously mentioned approaches for MDP and SG and their underlying ideas. To achieve this, we isolate objective-specific subroutines as well as identify objective-independent concepts. These structural concepts, while surprisingly simple, form the very essence of the unified solution.","lang":"eng"}],"acknowledgement":"This research was funded in part by DFG projects 383882557 “SUV” and 427755713 “GOPro”.","status":"public","publisher":"IEEE","quality_controlled":"1","doi":"10.1109/LICS56636.2023.10175771","year":"2023","volume":2023,"publication_status":"published","citation":{"ieee":"J.

None of the encoders, jammer and decoder is allowed to randomize using private or public randomness. This enforces a combinatorial nature of the problem. Our model covers a large family of channels studied in the literature, including all deterministic discrete memoryless noisy or noiseless MACs. In this work, given an arbitrary two-transmitter deterministic omniscient adversarial MAC, we characterize when the capacity region: 1) has nonempty interior (in particular, is two-dimensional); 2) consists of two line segments (in particular, has empty interior); 3) consists of one line segment (in particular, is one-dimensional); 4) or only contains (0,0) (in particular, is zero-dimensional). This extends a recent result by Wang et al. (201 9) from the point-to-point setting to the multiple access setting. Indeed, our converse arguments build upon their generalized Plotkin bound and involve delicate case analysis. One of the technical challenges is to take care of both “joint confusability” and “marginal confusability”. In particular, the treatment of marginal confusability does not follow from the point-to-point results by Wang et al.

A Z-channel with error fraction τ takes as input a length- n binary codeword and injects in an adversarial manner up to n τ asymmetric errors, i.e., errors that only zero out bits but do not flip 0’s to 1’s. It is known that the largest ( L - 1)-list-decodable code for the Z-channel with error fraction τ has exponential size (in n ) if τ is less than a critical value that we call the ( L - 1)- list-decoding Plotkin point and has constant size if τ is larger than the threshold. The ( L -1)-list-decoding Plotkin point is known to be L -1/L-1 – L -L/ L-1 , which equals 1/4 for unique-decoding with L -1 = 1. In this paper, we derive various results for the size of the largest codes above and below the list-decoding Plotkin point. In particular, we show that the largest ( L -1)-list-decodable code ε-above the Plotkin point, for any given sufficiently small positive constant ε > 0, has size Θ L (ε -3/2 ) for any L - 1 ≥ 1. We also devise upper and lower bounds on the exponential size of codes below the list-decoding Plotkin point."}]},{"OA_type":"closed access","doi":"10.1111/gcb.16667","year":"2023","volume":29,"citation":{"chicago":"Zhao, Jiacheng, Xiang Zhao, Donghai Wu, Naika Meili, and Simone Fatichi. “Satellite‐based Evidence Highlights a Considerable Increase of Urban Tree Cooling Benefits from 2000 to 2015.” <i>Global Change Biology</i>.

Tree cooling efficiency(TCE), defined as the temperature reduction for a 1% tree cover increase, plays animportant role in urban climate as it regulates the capacity of trees to alter the sur-face energy and water budget. However, the spatial variation and more importantly,temporal heterogeneity of TCE in global cities are not fully explored. Here, we usedLandsat-based tree cover and land surface temperature (LST) to compare TCEs at areference air temperature and tree cover level across 806 global cities and to exploretheir potential drivers with a boosted regression tree (BRT) machine learning model.From the results, we found that TCE is spatially regulated by not only leaf area index(LAI) but climate variables and anthropogenic factors especially city albedo, withouta specific variable dominating the others. However, such spatial difference is attenu-ated by the decrease of TCE with tree cover, most pronounced in midlatitude cities.During the period 2000–2015, more than 90% of analyzed cities showed an increas-ing trend in TCE, which is likely explained by a combined result of the increase in LAI,intensified solar radiation due to decreased aerosol content, increase in urban vaporpressure deficit (VPD) and decrease of city albedo. Concurrently, significant urbanafforestation occurred across many cities showing a global city-scale mean tree coverincrease of 5.3 ± 3.8% from 2000 to 2015. Over the growing season, such increasescombined with an increasing TCE were estimated to on average yield a midday sur-face cooling of 1.5 ± 1.3°C in tree-covered urban areas. These results are offeringnew insights into the use of urban afforestation as an adaptation to global warmingand urban planners may leverage them to provide more cooling benefits if trees areprimarily planted for this purpose.","lang":"eng"}],"publisher":"Wiley","issue":"11","status":"public","quality_controlled":"1","month":"06","extern":"1","_id":"22534","article_type":"original","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_created":"2026-07-27T12:30:24Z","date_updated":"2026-08-12T08:28:41Z","das_tickbox":"1","intvolume":"        29","publication":"Global Change Biology","oa_version":"None","author":[{"last_name":"Zhao","full_name":"Zhao, Jiacheng","first_name":"Jiacheng"},{"last_name":"Zhao","full_name":"Zhao, Xiang","first_name":"Xiang"},{"last_name":"Wu","full_name":"Wu, Donghai","first_name":"Donghai"},{"full_name":"Meili, Naika","first_name":"Naika","last_name":"Meili"},{"last_name":"Fatichi","full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","first_name":"Simone"}],"scopus_import":"1","publication_identifier":{"eissn":["1365-2486"],"issn":["1354-1013"]},"page":"3085-3097","article_processing_charge":"No","type":"journal_article","day":"01","fulldoi":"https://doi.org/10.1111/gcb.16667","language":[{"iso":"eng"}],"keyword":["Climate change","Remote sensing","Tree cooling efficiency","Tree cover","Urban afforestation"],"external_id":{"pmid":["36876991 "]},"date_published":"2023-06-01T00:00:00Z","pmid":1},{"publication_status":"published","citation":{"apa":"Chen, T., Meili, N., Fatichi, S., Hang, J., Tan, P.

This study assesses the change in the velocity of the water cycle over land at the global scale, whereas previous studies have mostly focused on changes in the atmospheric water cycle. The hydrological acceleration is quantified by a decrease in average residence time (RT) of water in the first meter of soil. The soil water RT is shown to be sensitive to the soil texture and seasonality of hydroclimatic variables. Despite substantial local variability, most of the RTs are in the range of 50–300 days. The global mean soil water RT declined at a rate of −2.30 and −0.36 days decade−1 (−1.6 to 1.0 days decade−1 the range of nine models) from 2001 to 2020 as measured by reanalysis and CMIP6 simulations for the historical scenario, respectively, which corresponds to −6.8 and −1.1 days °C−1 when expressed per degree of global warming over land. This acceleration is projected to continue at a rate of −1.35 days decade−1 (−3.4 to 0.0 days decade−1 the range of nine models) or −2.2 days °C−1 during the period 2015–2100 under the most extreme emission scenario: SSP 585. Changes in precipitation dominantly drive the acceleration of the terrestrial water cycle compared to changes in evapotranspiration. Rising temperatures and increasing carbon dioxide have opposite effects on the speed of the terrestrial water cycle with compensatory roles keeping RT relatively unchanged in the absence of PR trends.","lang":"eng"}],"fulldoi":"https://doi.org/10.1029/2022wr033970","date_published":"2023-08-01T00:00:00Z","language":[{"iso":"eng"}],"article_number":"e2022WR033970","author":[{"last_name":"Wang","first_name":"Y.","full_name":"Wang, Y."},{"first_name":"N.","full_name":"Meili, N.","last_name":"Meili"},{"last_name":"Fatichi","first_name":"Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","full_name":"Fatichi, Simone"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1029/2022WR033970"}],"publication_identifier":{"issn":["0043-1397"],"eissn":["1944-7973"]},"scopus_import":"1","day":"01","article_processing_charge":"No","type":"journal_article"}]
