In this paper, we introduce value positivity and uniform value positivity, two properties that refine the notion of optimality in the context of polynomially perturbed matrix games. The first concept captures how the value depends on the perturbation parameter, and the second consists of the existence of a fixed strategy that guarantees the value of the unperturbed matrix game for every sufficiently small positive parameter. We provide polynomial-time algorithms to check whether a polynomially perturbed matrix game satisfies these properties. We further provide the functional form for a parameterized optimal strategy and the value function. Finally, we translate our results to linear programming and stochastic games, where value positivity is related to the existence of robust solutions.","lang":"eng"}],"isi":1,"year":"2024"},{"doi":"10.48550/arXiv.2309.05488","type":"preprint","department":[{"_id":"LaEr"}],"publication_status":"draft","title":"Eigenstate thermalisation at the edge for Wigner matrices","project":[{"call_identifier":"H2020","_id":"62796744-2b32-11ec-9570-940b20777f1d","grant_number":"101020331","name":"Random matrices beyond Wigner-Dyson-Mehta"}],"author":[{"full_name":"Cipolloni, Giorgio","last_name":"Cipolloni","first_name":"Giorgio","id":"42198EFA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4901-7992"},{"full_name":"Erdös, László","last_name":"Erdös","orcid":"0000-0001-5366-9603","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87","first_name":"László"},{"full_name":"Henheik, Sven Joscha","last_name":"Henheik","id":"31d731d7-d235-11ea-ad11-b50331c8d7fb","orcid":"0000-0003-1106-327X","first_name":"Sven Joscha"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"external_id":{"arxiv":["2309.05488"]},"date_published":"2024-12-17T00:00:00Z","article_processing_charge":"No","corr_author":"1","related_material":{"record":[{"id":"19540","status":"public","relation":"dissertation_contains"}]},"date_created":"2025-04-11T08:19:22Z","_id":"19545","acknowledgement":"Supported by ERC Advanced Grant “RMTBeyond” No. 101020331.","oa_version":"Preprint","oa":1,"arxiv":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2309.05488"}],"OA_place":"repository","status":"public","citation":{"ista":"Cipolloni G, Erdös L, Henheik SJ.

We show that already a small noise of variance 1/N completely thermalises the bulk singular vectors, in particular they satisfy the strong form of Quantum Unique Ergodicity (QUE) with an optimal speed of convergence. In physics terms, we thus extend the Eigenstate Thermalisation Hypothesis, formulated originally by Deutsch [34] and proven for Wigner matrices in [23], to arbitrary non-Hermitian matrices with an i.i.d. noise. As a consequence we obtain an optimal lower bound on the diagonal overlaps of the corresponding non-Hermitian eigenvectors. This quantity, also known as the (square of the) eigenvalue condition number measuring the sensitivity of the eigenvalue to small perturbations, has notoriously escaped rigorous treatment beyond the explicitly computable Ginibre ensemble apart from the very recent upper bounds given in [7] and [45]. As a key tool, we develop a new systematic decomposition of general observables in random matrix theory that governs the size of products of resolvents with deterministic matrices in between.","lang":"eng"}],"year":"2024","isi":1,"date_updated":"2026-07-29T13:18:17Z","publication":"Journal of Functional Analysis","article_type":"original","language":[{"iso":"eng"}],"file_date_updated":"2025-06-24T13:14:21Z","day":"15","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","month":"08","OA_place":"publisher","has_accepted_license":"1","oa":1,"oa_version":"Published Version","status":"public","article_number":"110495","scopus_import":"1","publication_identifier":{"issn":["0022-1236"],"eissn":["1096-0783"]},"ddc":["510"],"ec_funded":1,"volume":287,"citation":{"ama":"Cipolloni G, Erdös L, Henheik SJ, Schröder DJ.

The main feature of our analysis is that we express the error terms in the optimal Schatten (tracial) norms of the observables, allowing us to track the exact dependence of the errors on their rank. In particular, for significantly overlapping observables with low rank the OTOC is shown to exhibit a significant local maximum at the scrambling time, a feature that may not have been noticed in the physics literature before.

Much of this can be attributed to massively increased scale, both in the size of the model as well as the amount of training data, from 100s of millions to 100s of billions, or even trillions. This trend is expected to continue, which, although exciting, also raises major practical concerns. Already today's 100+ billion parameter LLMs require top-of-the-line hardware just to run. Hence, it is clear that sustaining these developments will require significant efficiency advances.\r\n\r\nHistorically, one of the most practical ways of improving model efficiency has been compression, especially in the form of sparsity or quantization. While this has been studied extensively in the past, existing accurate methods are all designed for models around 100 million parameters; scaling them up to ones literally 1000x larger is highly challenging. In this thesis, we introduce a new unified sparsification and quantization approach OBC, which through additional algorithmic enhancements leads to GPTQ and SparseGPT, the first techniques fast and accurate enough to compress 100+ billion parameter models to 4- or even 3-bit precision and 50% weight-sparsity, respectively. Additionally, we show how weight-only quantizion does not just bring space savings but also up to 4.5x faster generation speed, via custom GPU kernels.\r\n\r\nIn fact, we show for the first time that it is possible to develop an FP16 times INT4 mixed-precision matrix multiplication kernel, called Marlin, which comes close to simultaneously maximizing both memory and compute utilization, making weight-only quantization highly practical even for multi-user serving. Further, we demonstrate that GPTQ can be scaled to widely overparametrized trillion-parameter models, where extreme sub-1-bit compression rates can be achieved without any inference slow-down, by co-designing a bespoke entropy coding scheme together with an efficient kernel.\r\n\r\nFinally, we also study compression from the perspective of someone with access to massive amounts of compute resources for training large models completely from scratch. Here the key questions evolve around the joint scaling behavior between compression, model size, and amount of training data used. Based on extensive experimental results for both vision and text models, we introduce the first scaling law which accurately captures the relationship between weight-sparsity, number of non-zero weights and data. This further allows us to characterize the optimal sparsity, which we find to increase the longer a fixed cost model is being trained.\r\n\r\nOverall, this thesis presents contributions to three different angles of large model efficiency: affordable but accurate algorithms, highly efficient systems implementations, and fundamental scaling laws for compressed training."}],"year":"2024","month":"09","language":[{"iso":"eng"}],"alternative_title":["ISTA Thesis"],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","file_date_updated":"2024-09-06T16:24:59Z","day":"05","status":"public","publication_identifier":{"issn":["2663-337X"]},"degree_awarded":"PhD","OA_place":"publisher","has_accepted_license":"1","oa":1,"oa_version":"Published Version","ec_funded":1,"citation":{"ama":"Frantar E.

In this setting, we identify the first scaling law describing the relationship between weight sparsity, number of non-zero parameters, and amount of training data, which we validate empirically across model and data scales; on ViT/JFT-4B and T5/C4. These results allow us to characterize the \"optimal sparsity\", the sparsity level which yields the best performance for a given effective model size and training budget. For a fixed number of non-zero parameters, we identify that the optimal sparsity increases with the amount of data used for training.

For example, the SwitchTransformer-c2048 model has 1.6 trillion parameters, requiring 3.2TB of accelerator memory to run efficiently, which makes practical deployment challenging and expensive. In this paper, we present a solution to this memory problem, in form of a new compression and execution framework called QMoE. Specifically, QMoE consists of a scalable algorithm which accurately compresses trillion-parameter MoEs to less than 1 bit per parameter, in a custom format co-designed with bespoke GPU decoding kernels to facilitate efficient end-to-end compressed inference, with minor runtime overheads relative to uncompressed execution. Concretely, QMoE can compress the 1.6 trillion parameter SwitchTransformer-c2048 model to less than 160GB (20x compression, 0.8 bits per parameter) at only minor accuracy loss, in less than a day on a single GPU. This enables, for the first time, the execution of a trillion-parameter model on affordable commodity hardware, like a single server with 4x NVIDIA A6000 or 8x NVIDIA 3090 GPUs, at less than 5% runtime overhead relative to ideal uncompressed inference.

Hydro-pedotransfer functions (PTFs) relate easy-to-measure and readily available soil information to soil hydraulic properties (SHPs) for applications in a wide range of process-based and empirical models, thereby enabling the assessment of soil hydraulic effects on hydrological, biogeochemical, and ecological processes. At least more than 4 decades of research have been invested to derive such relationships. However, while models, methods, data storage capacity, and computational efficiency have advanced, there are fundamental concerns related to the scope and adequacy of current PTFs, particularly when applied to parameterise models used at the field scale and beyond. Most of the PTF development process has focused on refining and advancing the regression methods, while fundamental aspects have remained largely unconsidered. Most soil systems are not represented in PTFs, which have been built mostly for agricultural soils in temperate climates. Thus, existing PTFs largely ignore how parent material, vegetation, land use, and climate affect processes that shape SHPs. The PTFs used to parameterise the Richards–Richardson equation are mostly limited to predicting parameters of the van Genuchten–Mualem soil hydraulic functions, despite sufficient evidence demonstrating their shortcomings. Another fundamental issue relates to the diverging scales of derivation and application, whereby PTFs are derived based on laboratory measurements while often being applied at the field to regional scales. Scaling, modulation, and constraining strategies exist to alleviate some of these shortcomings in the mismatch between scales. These aspects are addressed here in a joint effort by the members of the International Soil Modelling Consortium (ISMC) Pedotransfer Functions Working Group with the aim of systematising PTF research and providing a roadmap guiding both PTF development and use. We close with a 10-point catalogue for funders and researchers to guide review processes and research.</jats:p>"}],"month":"07","PlanS_conform":"1","day":"29","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","language":[{"iso":"eng"}],"extern":"1","scopus_import":"1","publication_identifier":{"issn":["1027-5606"],"eissn":["1607-7938"]},"status":"public","has_accepted_license":"1","oa":1,"oa_version":"Published Version","OA_place":"publisher","main_file_link":[{"open_access":"1","url":"https://doi.org/10.5194/hess-28-3391-2024"}],"citation":{"ama":"Weber TKD, Weihermüller L, Nemes A, et al.

Several studies have shown that such scaling laws hold also for natural ecosystems, including individual trees and forests, riverine metabolism, and river network organization. However, the derivation of scaling laws for catchment-scale water and carbon fluxes has not been achieved so far. Here, we focus on scaling relations of catchment green metabolism, defined as the set of ecohydrological and biogeochemical processes through which vegetation assemblages in catchments maintain their structure and react to the surrounding environment. By revising existing plant size–density relationships and integrating them across large-scale domains, we show that the ecohydrological fluxes occurring at the catchment scale are invariant with respect to the above-ground vegetation biomass per unit area of the basin, while they scale linearly with catchment size. We thus demonstrate that the sublinear scaling of plant metabolism results in an isometric scaling at catchment and regional scales. Deviations from such predictions are further shown to collapse onto a common distribution, thus incorporating natural fluctuations due to resource limitations into a generalized scaling theory. Results from scaling arguments are supported by hyperresolution ecohydrological simulations and remote sensing observations.","lang":"eng"}],"publication":"Proceedings of the National Academy of Sciences","das_tickbox":"1","date_updated":"2026-07-30T11:27:23Z","ddc":["550"],"citation":{"ieee":"F.

Urban expansion is altering the permeability of the land, thus increasing the risk of flooding. This study investigates the impact of urban morphology on pluvial floodwater distribution in 15 urban catchments across England, UK, to provide an analysis of how urban morphology influences flood magnitude. Using a cellular automata-based model, pluvial flood simulations were conducted for catchments characterized by diverse urban morphologies. Then a series of machine learning models were adopted to reveal the relationships between the morphological characteristics of urban configurations (e.g., building footprints, impervious surfaces, street network, topography) and pluvial flooding. These models were used to identify and quantify the effects of key urban morphological indicators on pluvial flooding. The results indicate that, although the total area of impervious surfaces plays the most significant role in floodwater distribution, the edge density (ED) of building footprints and impervious surfaces also influences this process. Synthetic experiments with an exemplary urban fabric show that decreasing “ED of building footprint” and increasing “ED of impervious surface” can mitigate flood volume by up to 6.3 % at 100 % drainage efficiency and 7.8 % at 50 % efficiency.

Yet, the role of CUE in regulating SOC storage remains debated, with evidence for both positive and negative SOC‐CUE relations. Here, we use a combination of measured data around the world and numerical simulations to explore SOC‐CUE relations accounting for temperature (T) effects on CUE. Results reveal that the sign of the CUE‐T relation controls the direction of the SOC‐CUE relations. A negative CUE‐T relation leads to a positive SOC‐CUE relation and vice versa, highlighting that CUE‐T patterns significantly affect how organic carbon is used by microbes and hence SOC‐CUE relations. Numerical results also confirm the observed negative SOC‐T relation, regardless of the CUE‐T patterns, implying that temperature plays a more dominant role than CUE in controlling SOC storage. The SOC‐CUE relation is usually negative when temperature effects are isolated, even though it can become positive when nonlinear microbial turnover is considered. These results indicate a dominant role of CUE‐T patterns in controlling the SOC‐CUE relation. Our findings help to better understand SOC and microbial responses to a warming climate.</jats:p>","lang":"eng"}],"year":"2024","PlanS_conform":"1","month":"09","extern":"1","language":[{"iso":"eng"}],"article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","article_number":"e17492","status":"public","publication_identifier":{"eissn":["1365-2486"],"issn":["1354-1013"]},"scopus_import":"1","OA_place":"publisher","main_file_link":[{"url":"https://doi.org/10.1111/gcb.17492","open_access":"1"}],"oa_version":"Published Version","has_accepted_license":"1","oa":1,"volume":30,"citation":{"apa":"Luo, Z., Ren, J., Manzoni, S., &#38; Fatichi, S.

This is based on\r\njoint work with Leonhard Hochfilzer.\r\n(2) We study rational points on smooth complete intersections X defined by cubic and\r\nquadratic hypersurfaces over Fq(t). We refine the Farey dissection of the “unit square”\r\ndeveloped by Vishe [202] and use the circle method with a Kloosterman refinement to\r\nestablish an asymptotic formula for the number of rational points of bounded height on\r\nX when dim(X) ≥ 23. Under the same hypotheses, we also verify weak approximation.\r\n(3) In joint work with Hochfilzer, we obtain upper bounds for the number of rational points of\r\nbounded height on del Pezzo surfaces of low degree over any global field. Our approach\r\nis to take hyperplane sections, which reduces the problem to uniform estimates for the\r\nnumber of rational points on curves.\r\n(4) We develop a version of the circle method capable of counting Fq-points on jet schemes\r\nof moduli spaces of rational curves on hypersurfaces. Combining this with a spreading\r\nout argument and a result of Mustaţă [150], this allows us to show that these moduli\r\nspaces only have canonical singularities under suitable assumptions on the degree and the\r\ndimension.\r\nIn addition, we give an overview of guiding questions and conjectures in the field of rational\r\npoints and explain the basic mechanism underlying the circle method.\r\n","lang":"eng"}],"supervisor":[{"full_name":"Browning, Timothy D","id":"35827D50-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8314-0177","first_name":"Timothy D","last_name":"Browning"}],"das_tickbox":"0","date_updated":"2026-08-06T10:33:33Z","alternative_title":["ISTA Thesis"],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","file_date_updated":"2024-09-25T14:08:57Z","day":"23","language":[{"iso":"eng"}],"supplementarymaterial":"no","month":"09","publisher":"Institute of Science and Technology Austria","type":"dissertation","doi":"10.15479/at:ista:18132","department":[{"_id":"GradSch"},{"_id":"TiBr"}],"publication_status":"published","file":[{"date_updated":"2024-09-23T18:49:22Z","checksum":"2f8cf5cefdab108b1979caa8146cae9a","relation":"source_file","file_id":"18133","access_level":"closed","creator":"jglas","file_size":5382106,"date_created":"2024-09-23T18:49:22Z","content_type":"application/x-zip-compressed","file_name":"PhDthesis (3).zip"},{"file_name":"example-phd.pdf","content_type":"application/pdf","date_created":"2024-09-25T14:08:57Z","file_size":2380127,"creator":"jglas","access_level":"open_access","file_id":"18140","success":1,"relation":"main_file","checksum":"08bb6f14c42b47ff25882a2ce3ea0d8a","date_updated":"2024-09-25T14:08:57Z"}],"researchdata_availability":"no","title":"Counting rational points over function fields","project":[{"grant_number":"P36278","_id":"bd8a4fdc-d553-11ed-ba76-80a0167441a3","name":"Rational curves via function field analytic number theory"}],"author":[{"full_name":"Glas, Jakob","first_name":"Jakob","id":"d6423cba-dc74-11ea-a0a7-ee61689ff5fb","last_name":"Glas"}],"tmp":{"short":"CC BY-NC (4.0)","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","image":"/images/cc_by_nc.png","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode"},"date_published":"2024-09-23T00:00:00Z","page":"195","article_processing_charge":"No","corr_author":"1","related_material":{"record":[{"id":"18173","relation":"part_of_dissertation","status":"public"},{"id":"18295","relation":"part_of_dissertation","status":"public"},{"id":"18294","relation":"part_of_dissertation","status":"public"},{"id":"18293","status":"public","relation":"part_of_dissertation"}]},"date_created":"2024-09-23T18:58:08Z","_id":"18132"},{"article_type":"original","language":[{"iso":"eng"}],"day":"08","file_date_updated":"2024-04-26T10:34:07Z","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","month":"04","supplementarymaterial":"no","abstract":[{"lang":"eng","text":"Materials with low thermal conductivity usually have complex crystal structures. Herein we experimentally find that a simple crystal structure material AgTlI2 (I4/mcm) owns an extremely low thermal conductivity of 0.25 W/mK at room temperature. To understand this anomaly, we perform in-depth theoretical studies based on ab initio molecular dynamics simulations and anharmonic lattice dynamics. We find that the unique atomic arrangement and weak chemical bonding provide a permissive environment for strong oscillations of Ag atoms, leading to a considerable rattling behaviour and giant lattice anharmonicity. This feature is also verified by the experimental probability density function refinement of single-crystal diffraction. The particularly strong anharmonicity breaks down the conventional phonon gas model, giving rise to non-negligible wavelike phonon behaviours in AgTlI2 at 300 K. Intriguingly, unlike many strongly anharmonic materials where a small propagative thermal conductivity is often accompanied by a large diffusive thermal conductivity, we find an unusual coexistence of ultralow propagative and diffusive thermal conductivities in AgTlI2 based on the thermal transport unified theory. This study underscores the potential of simple crystal structures in achieving low thermal conductivity and encourages further experimental research to enrich the family of materials with ultralow thermal conductivity."}],"year":"2024","isi":1,"dataavailabilitystatement":"All necessary source data files generated for this study are available in the SI repository https://github.com/ZengZezhu/Thermal-conductivity-AgTlI2 see ref 72.\r\n72.

In this first of two parts focusing on structure generation methods, many crystal structure prediction (CSP) methods performed well for the small but flexible agrochemical compound, successfully reproducing the experimentally observed crystal structures, while few groups were successful for the systems of higher complexity. A powder X-ray diffraction (PXRD) assisted exercise demonstrated the use of CSP in successfully determining a crystal structure from a low-quality PXRD pattern. The use of CSP in the prediction of likely cocrystal stoichiometry was also explored, demonstrating multiple possible approaches. Crystallographic disorder emerged as an important theme throughout the test as both a challenge for analysis and a major achievement where two groups blindly predicted the existence of disorder for the first time. Additionally, large-scale comparisons of the sets of predicted crystal structures also showed that some methods yield sets that largely contain the same crystal structures.","lang":"eng"}],"isi":1,"year":"2024"},{"arxiv":1,"oa_version":"Preprint","oa":1,"has_accepted_license":"1","article_number":"161101","status":"public","publication_identifier":{"eissn":["1089-7550"],"issn":["0021-8979"]},"scopus_import":"1","ddc":["530"],"volume":135,"ec_funded":1,"citation":{"ista":"Dong H, Shi Y, Ying P, Xu K, Liang T, Wang Y, Zeng Z, Wu X, Zhou W, Xiong S, Chen S, Fan Z. 2024.

An essential requirement for reliably predicting heat transport properties is the use of accurate and efficient interatomic potentials. Recently, machine-learned potentials (MLPs) have shown great promise in providing the required accuracy for a broad range of materials. In this mini-review and tutorial, we delve into the fundamentals of heat transport, explore pertinent MD simulation methods, and survey the applications of MLPs in MD simulations of heat transport. Furthermore, we provide a step-by-step tutorial on developing MLPs for highly efficient and predictive heat transport simulations, utilizing the neuroevolution potentials as implemented in the GPUMD package. Our aim with this mini-review and tutorial is to empower researchers with valuable insights into cutting-edge methodologies that can significantly enhance the accuracy and efficiency of MD simulations for heat transport studies.","lang":"eng"}],"isi":1,"year":"2024","das_tickbox":"1","dataavailabilitystatement":"All the training and test datasets and the trained NEP models for crystalline silicon are freely available at https://gitlab.com/brucefan1983/nep-data.
