Recent theoretical studies and experiments in simpler, shear-driven flows suggest that the onset of turbulence is a directed-percolation non-equilibrium phase transition, but whether these findings are generic and also apply to open or pressure-driven flows is unknown. In pipe flow, the extremely long time scales near the transition make direct observations of critical behaviour virtually impossible. Here we find a technical solution to that limitation and show that the universality class of the transition is directed percolation, from which a jammed phase of puffs emerges above the critical point. Our method is to experimentally characterize all pairwise interactions between localized patches of turbulence puffs and use these interactions as input for renormalization group and computer simulations of minimal models that extrapolate to long length and time scales. The strong interactions in the jamming regime enable us to explicitly measure the turbulent fraction and confirm model predictions. Our work shows that directed-percolation scaling applies beyond simple closed shear flows and underscores how statistical mechanics can lead to profound, quantitative and predictive insights on turbulent flows and their phases."}],"acknowledgement":"We gratefully acknowledge the assistance of J.

Since the\r\ninception of experimental eforts toward building a quantum computer, the community has\r\nfaced challenges in engineering such a system. Among the various methods of implementing a\r\nquantum computer, superconducting qubits have shown fast gates close to tens of nanoseconds,\r\nwith the state-of-the-art reaching a coherence of a few milliseconds. However, achieving\r\nsimultaneously long lifetimes with fast qubit operations poses an inherent paradox. Qubits\r\nwith high coherence require isolation from the environment, while fast operation necessitates\r\nstrong coupling of the qubit. This thesis approaches this issue by proposing the idea of\r\nengineering superconducting qubits capable of transitioning between operating in a protected\r\nregime, where the qubit is completely isolated from the environment, and coupling to the\r\ncommunication channels as needed. In this direction, we use the geometric superinductor to\r\nscan the parameter space of rf-SQUID devices, searching for a regime where we can take the\r\nqubit protection to its extreme.\r\n\r\nThis leads us to the inductively shunted transmon (IST) regime, characterized by EJ /EC ≫ 1\r\nand EJ /EL ≫ 1, where the circuit potential exhibits a double well with a large barrier\r\nseparating the local ground states of each quantum well. In this regime, although it is\r\nanticipated that the two quantum wells would be isolated from each other, we observe single\r\nfuxon tunneling between them. The interplay of the cavity photons and the fuxon transition\r\nforms a rich physical system, containing resonance conditions that allow the preparation of the\r\nfuxon ground or excited states. This enables us to study the relaxation rate of such transition\r\nand show that it can be as large as 3.6 hours. Dynamically controlling the barrier height\r\nbetween the two quantum wells allows for controllable coupling, which scales exponentially,\r\nfor a qubit encoded in two fuxon states.\r\nThe 0-π qubit is one of the very few known superconducting circuit types that ofers exponential\r\nprotection from both relaxation and dephasing simultaneously. However, this qubit is not\r\nexempt from the fact that such protection comes at the expense of complex readout and\r\ncontrol. In this thesis, we propose a way to controllably break the circuit symmetry, the\r\nkey reason for the protection, to momentarily restore the ability to control and manipulate\r\nthe qubit. An asymmetry in capacitances and inductances in the 0-π circuit is detrimental\r\nsince they lead to coupling of the protected state to the thermally occupied parasitic mode\r\nof the circuit. However, here we try to exploit a controlled asymmetry in Josephson energies\r\nand show that this can be used as a tunable coupler between the protected states. In the\r\nfuture, this should allow to perform gate operations by dynamically controlling the asymmetry\r\ninstead of driving the protected transition with microwave pulses. Therefore, we believe that\r\nthe proposed method can make the use of protected qubits more practical in experimental\r\nrealizations of quantum computing."}],"publisher":"Institute of Science and Technology Austria","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","file_date_updated":"2024-06-20T11:52:22Z","department":[{"_id":"GradSch"},{"_id":"JoFi"}],"alternative_title":["ISTA Thesis"],"status":"public","corr_author":"1","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","citation":{"ista":"Hassani F. 2024.

Notably, the severity of these sensory symptoms is often predictive of the expression of other autistic traits. However, the origin of these perceptual deficits remains largely elusive. Here, we show a recurrent impairment in visual threat perception that is similarly impaired in 3 independent mouse models of ASD with different molecular aetiologies. Interestingly, this deficit is associated with reduced avoidance of threatening environments—a nonperceptual trait. Focusing on a common cause of ASDs, the Setd5 gene mutation, we define the molecular mechanism. We show that the perceptual impairment is caused by a potassium channel (Kv1)-mediated hypoexcitability in a subcortical node essential for the initiation of escape responses, the dorsal periaqueductal grey (dPAG). Targeted pharmacological Kv1 blockade rescued both perceptual and place avoidance deficits, causally linking seemingly unrelated trait deficits to the dPAG. Furthermore, we show that different molecular mechanisms converge on similar behavioural phenotypes by demonstrating that the autism models Cul3 and Ptchd1, despite having similar behavioural phenotypes, differ in their functional and molecular alteration. Our findings reveal a link between rapid perception controlled by subcortical pathways and appropriate learned interactions with the environment and define a nondevelopmental source of such deficits in ASD."}],"acknowledgement":"This work was supported by a European Research Council Starting Grant 756502 (MJ).

To obtain quantitative estimates on the speed of convergence, we consider variations on the classical Kurdyka–Łojasiewicz inequality for a large class of parameter functions. Our assumptions are given in terms of the initial data, without any reference to an equilibrium point. The main results are convergence statements for gradient flow curves and proximal point sequences to a global minimiser, together with sharp quantitative estimates on the speed of convergence. These convergence results apply in the general setting of lower semicontinuous functionals on complete metric spaces, generalising recent results for smooth functionals on Rn. While the non-smooth setting covers very general spaces, it is also useful for (non)-smooth functionals on Rn.\r\n.","lang":"eng"}],"acknowledgement":"The authors gratefully acknowledges support by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No. 716117).

For most of the thesis, the focus is on smooth complex varieties with\r\nan action of a principally paired group, e.g. a parabolic subgroup of a reductive group.\r\nThe fundamental theorem 5.2.11 from co-authored article [66] says that if the principal\r\nnilpotent has a unique zero, then the zero scheme over the Kostant section is isomorphic\r\nto the spectrum of the equivariant cohomology ring, remembering the grading in terms of\r\na C^* action. A similar statement is proved also for the G-invariant functions on the total\r\nzero scheme over the whole Lie algebra. Additionally, we are able to prove an analogous\r\nresult for the GKM spaces, which poses the question on a joint generalisation.\r\nWe also tackle the situation of a singular variety. As long as it is embedded in a smooth\r\nvariety with regular action, we are able to study its cohomology as well by means of\r\nthe zero scheme. In case of e.g. Schubert varieties this determines the cohomology ring\r\ncompletely. In largest generality, this allows us to see a significant part of the cohomology\r\nring.\r\nWe also show (Theorem 6.2.1) that the cohomology ring of spherical varieties appears as\r\nthe ring of functions on the zero scheme. The computational aspect is not easy, but one\r\ncan hope that this can bring some concrete information about such cohomology rings.\r\nLastly, the K-theory conjecture 6.3.1 is studied, with some results attained for GKM\r\nspaces.\r\nThe thesis includes also an introduction to group actions on algebraic varieties. In\r\nparticular, the vector fields associated to the actions are extensively studied. We also\r\nprovide a version of the Kostant section for arbitrary principally paired group, which\r\nparametrises the regular orbits in the Lie algebra of an algebraic group. Before proving\r\nthe main theorem, we also include a historical overview of the field. In particular we bring\r\ntogether the results of Akyildiz, Carrell and Lieberman on non-equivariant cohomology\r\nrings.","lang":"eng"}],"page":"117","publication_status":"published","article_processing_charge":"No","oa":1,"OA_place":"publisher","degree_awarded":"PhD","ddc":["516"],"day":"25","author":[{"full_name":"Rychlewicz, Kamil P","first_name":"Kamil P","id":"85A07246-A8BF-11E9-B4FA-D9E3E5697425","last_name":"Rychlewicz"}],"supervisor":[{"full_name":"Hausel, Tamás","first_name":"Tamás","orcid":"0000-0002-9582-2634","id":"4A0666D8-F248-11E8-B48F-1D18A9856A87","last_name":"Hausel"}],"language":[{"iso":"eng"}],"year":"2024","file":[{"file_id":"17179","relation":"source_file","file_name":"thesis.zip","checksum":"1610063569f5452f8a5acef728c2fc26","date_created":"2024-06-26T20:56:27Z","file_size":2761814,"date_updated":"2024-06-26T21:00:14Z","creator":"krychlew","content_type":"application/zip","access_level":"closed"},{"file_size":3695952,"date_updated":"2024-06-26T20:58:24Z","date_created":"2024-06-26T20:58:24Z","creator":"krychlew","content_type":"application/pdf","access_level":"open_access","file_id":"17180","relation":"main_file","file_name":"thesis.pdf","checksum":"7bbadb1fbc9ed2a1ecf54597f88af99c"}],"publication_identifier":{"issn":["2663-337X"]}},{"project":[{"grant_number":"26777","name":"Exploring protein dynamics by solid-state MAS NMR through specific labeling approaches","_id":"7be609c4-9f16-11ee-852c-85015ce2b9b0"}],"scopus_import":"1","date_created":"2024-06-23T22:01:02Z","date_updated":"2025-06-11T13:26:12Z","quality_controlled":"1","volume":5,"oa_version":"Published Version","_id":"17161","month":"06","doi":"10.5194/mr-5-69-2024","type":"journal_article","has_accepted_license":"1","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":" 5","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2024-06-11T00:00:00Z","citation":{"ista":"Aebischer K, Becker LM, Schanda P, Ernst M. 2024.

For spin relaxation, this can easily be understood from the sampling frequencies of the spectral-density function by different relaxation-rate constants. In addition to data from relaxation measurements, determining dynamically averaged anisotropic interactions in magic-angle spinning (MAS) solid-state NMR allows for better quantification of the amplitude of molecular motion. For partially averaged anisotropic interactions, the relevant timescales of motion are not so clearly defined. Whether the averaging depends on the experimental methods (e.g., pulse sequences) or conditions (e.g., MAS frequency, magnitude of anisotropic interaction, radio-frequency field amplitudes) is not fully understood. To investigate these questions, we performed numerical simulations of dynamic systems based on the stochastic Liouville equation using several experiments for recoupling the dipolar coupling, chemical-shift anisotropy or quadrupolar coupling. As described in the literature, the transition between slow motion, where parameters characterizing the anisotropic interaction are not averaged, and fast motion, where the tensors are averaged leading to a scaled anisotropic quantity, occurs over a window of motional rate constants that depends mainly on the strength of the interaction. This transition region can span 2 orders of magnitude in exchange-rate constants (typically in the microsecond range) but depends only marginally on the employed recoupling scheme or sample spinning frequency. The transition region often coincides with a fast relaxation of coherences, making precise quantitative measurements difficult. Residual couplings in off-magic-angle experiments, however, average over longer timescales of motion. While in principle one may gain information on the timescales of motion from the transition area, extracting such information is hampered by low signal-to-noise ratio in experimental spectra due to fast relaxation that occurs in the same region."}],"acknowledgement":"We would like to thank Kay Saalwächter for pointing out important aspects of the intermediate regime during the open review process.

In this work, we consider two classical quantitative problems in cost analysis for probabilistic programs. The first problem is to find a bound on the expected total cost of the program. This is a natural measure for the resource usage of the program and can also be directly applied to average-case runtime analysis. The second problem asks for a tail bound, i.e. given a threshold t the goal is to find a probability bound p such that ℙ[total cost ≥ t] ≤ p. Intuitively, given a threshold t on the resource, the problem is to find the likelihood that the total cost exceeds this threshold.\r\nFirst, for expectation bounds, a major obstacle in previous works on cost analysis is that they can handle only non-negative costs or bounded variable updates. In contrast, we provide a new variant of the standard notion of cost martingales, that allows us to find expectation bounds for a class of programs with general positive or negative costs and no restriction on the variable updates. More specifically, our approach is applicable as long as there is a lower bound on the total cost incurred along every path.\r\nSecond, for tail bounds, all previous methods are limited to programs in which the expected total cost is finite. In contrast, we present a novel approach, based on a combination of our martingale-based method for expectation bounds with a quantitative safety analysis, to obtain a solution to the tail bound problem that is applicable even to programs with infinite expected cost. Specifically, this allows us to obtain runtime tail bounds for programs that do not terminate almost-surely.\r\nIn summary, we provide a novel combination of martingale-based cost analysis and quantitative safety analysis that is able to find expectation and tail cost bounds for probabilistic programs, without the restrictions of non-negative costs, bounded updates, or finiteness of the expected total cost. Finally, we provide experimental results showcasing that our approach can solve instances that were beyond the reach of previous methods."}],"author":[{"full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","last_name":"Chatterjee"},{"first_name":"Amir Kafshdar","full_name":"Goharshady, Amir Kafshdar","orcid":"0000-0003-1702-6584","last_name":"Goharshady","id":"391365CE-F248-11E8-B48F-1D18A9856A87"},{"id":"b21b0c15-30a2-11eb-80dc-f13ca25802e1","last_name":"Meggendorfer","orcid":"0000-0002-1712-2165","full_name":"Meggendorfer, Tobias","first_name":"Tobias"},{"full_name":"Zikelic, Dorde","first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","last_name":"Zikelic","orcid":"0000-0002-4681-1699"}],"day":"29","ddc":["000"],"issue":"OOPSLA1","article_processing_charge":"Yes (in subscription journal)","oa":1,"year":"2024","article_type":"original","language":[{"iso":"eng"}],"file":[{"file_name":"2024_ProcACMProgLanguage_Chatterjee.pdf","file_id":"17182","relation":"main_file","checksum":"9243ded966f71df1572be5466019be5c","creator":"dernst","success":1,"file_size":413096,"date_created":"2024-06-27T07:48:16Z","date_updated":"2024-06-27T07:48:16Z","content_type":"application/pdf","access_level":"open_access"}],"publication_identifier":{"eissn":["2475-1421"]},"publication":"Proceedings of the ACM on Programming Languages","doi":"10.1145/3649824","scopus_import":"1","project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","call_identifier":"H2020"}],"_id":"17162","oa_version":"Published Version","month":"04","date_created":"2024-06-23T22:01:02Z","date_updated":"2025-04-14T07:52:47Z","quality_controlled":"1","volume":8,"type":"journal_article","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"has_accepted_license":"1","article_number":"107","status":"public","ec_funded":1,"intvolume":" 8","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2024-04-29T00:00:00Z","citation":{"mla":"Chatterjee, Krishnendu, et al. “Quantitative Bounds on Resource Usage of Probabilistic Programs.” Proceedings of the ACM on Programming Languages, vol. 8, no.

In the first part, we consider the random\r\nvariable X := Tr(f1(W)A1 . . . fk(W)Ak) where W is an N × N Hermitian Wigner matrix, k ∈ N, and we choose (possibly N-dependent) regular functions f1, . . . , fk as well as\r\nbounded deterministic matrices A1, . . . , Ak. In this context, we prove a functional central\r\nlimit theorem on macroscopic and mesoscopic scales, showing that the fluctuations of X\r\naround its expectation are Gaussian and that the limiting covariance structure is given\r\nby a deterministic recursion. We further give explicit error bounds in terms of the scaling\r\nof f1, . . . , fk and the number of traceless matrices among A1, . . . , Ak, thus extending\r\nthe results of Cipolloni, Erdős and Schröder [40] to products of arbitrary length k ≥ 2.\r\nAnalyzing the underlying combinatorics leads to a non-recursive formula for the variance\r\nof X as well as the covariance of X and Y := Tr(fk+1(W)Ak+1 . . . fk+ℓ(W)Ak+ℓ) of similar\r\nbuild. When restricted to polynomials, these formulas reproduce recent results of Male,\r\nMingo, Peché, and Speicher [107], showing that the underlying combinatorics of noncrossing partitions and annular non-crossing permutations continue to stay valid beyond\r\nthe setting of second-order free probability theory. As an application, we consider the\r\nfluctuation of Tr(eitW A1e\r\n−itW A2)/N around its thermal value Tr(A1) Tr(A2)/N2 when t\r\nis large and give an explicit formula for the variance.\r\nThe second part of the thesis collects three smaller projects focusing on different random\r\nmatrix models. In the first project, we show that a class of weakly perturbed Hamiltonians\r\nof the form Hλ = H0 + λW, where W is a Wigner matrix, exhibits prethermalization.\r\nThat is, the time evolution generated by Hλ relaxes to its ultimate thermal state via an\r\nintermediate prethermal state with a lifetime of order λ\r\n−2\r\n. As the main result, we obtain\r\na general relaxation formula, expressing the perturbed dynamics via the unperturbed\r\ndynamics and the ultimate thermal state. The proof relies on a two-resolvent global law\r\nfor the deformed Wigner matrix Hλ.\r\nThe second project focuses on correlated random matrices, more precisely on a correlated N × N Hermitian random matrix with a polynomially decaying metric correlation\r\nstructure. A trivial a priori bound shows that the operator norm of this model is stochastically dominated by √\r\nN. However, by calculating the trace of the moments of the matrix\r\nand using the summable decay of the cumulants, the norm estimate can be improved to a\r\nbound of order one.\r\nIn the third project, we consider a multiplicative perturbation of the form UA(t) where U\r\nis a unitary random matrix and A = diag(t, 1, ..., 1). This so-called UA model was\r\nfirst introduced by Fyodorov [73] for its applications in scattering theory. We give a\r\ngeneral description of the eigenvalue trajectories obtained by varying the parameter t and\r\nintroduce a flow of deterministic domains that separates the outlier resulting from the\r\nrank-one perturbation from the typical eigenvalues for all sub-critical timescales. The\r\nresults are obtained under generic assumptions on U that hold for various unitary random\r\nmatrices, including the circular unitary ensemble (CUE) in the original formulation of\r\nthe model."}],"title":"Central limit theorems for random matrices: From resolvents to free probability"},{"alternative_title":["LIPIcs"],"arxiv":1,"ec_funded":1,"status":"public","intvolume":" 293","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2024-06-06T00:00:00Z","citation":{"ista":"Attali D, Kourimska H, Fillmore CD, Ghosh I, Lieutier A, Stephenson ER, Wintraecken M. 2024.

In their work, Niyogi, Smale, and Weinberger studied samples of C² manifolds with positive reach embedded in ℝ^d. We extend their results in the following ways: - As the ambient space we consider both ℝ^d and Riemannian manifolds with lower bounded sectional curvature. - In both types of ambient spaces, we study sets of positive reach - a significantly more general setting than C² manifolds - as well as general manifolds of positive reach. - The sample P of a set (or a manifold) 𝒮 of positive reach may be noisy. We work with two one-sided Hausdorff distances - ε and δ - between P and 𝒮. We provide tight bounds in terms of ε and δ, that guarantee that there exists a parameter r such that the union of balls of radius r centred at the sample P deformation-retracts to 𝒮. We exhibit their tightness by an explicit construction. We carefully distinguish the roles of δ and ε. This is not only essential to achieve tight bounds, but also sensible in practical situations, since it allows one to adapt the bound according to sample density and the amount of noise present in the sample separately."}],"ddc":["516"],"day":"06","author":[{"last_name":"Attali","full_name":"Attali, Dominique","first_name":"Dominique"},{"full_name":"Kourimska, Hana","first_name":"Hana","last_name":"Kourimska","id":"D9B8E14C-3C26-11EA-98F5-1F833DDC885E","orcid":"0000-0001-7841-0091"},{"last_name":"Fillmore","id":"35638A5C-AAC7-11E9-B0BF-5503E6697425","first_name":"Christopher D","full_name":"Fillmore, Christopher D"},{"full_name":"Ghosh, Ishika","first_name":"Ishika","id":"ee449b28-344d-11ef-a6d5-9ca430e9e9ff","last_name":"Ghosh"},{"last_name":"Lieutier","first_name":"André","full_name":"Lieutier, André"},{"orcid":"0000-0002-6862-208X","id":"2D04F932-F248-11E8-B48F-1D18A9856A87","last_name":"Stephenson","first_name":"Elizabeth R","full_name":"Stephenson, Elizabeth R"},{"orcid":"0000-0002-7472-2220","id":"307CFBC8-F248-11E8-B48F-1D18A9856A87","last_name":"Wintraecken","first_name":"Mathijs","full_name":"Wintraecken, Mathijs"}],"article_processing_charge":"No","oa":1},{"issue":"3","author":[{"orcid":"0000-0001-8457-2572","last_name":"Cheung","id":"471195F6-F248-11E8-B48F-1D18A9856A87","first_name":"Giselle T","full_name":"Cheung, Giselle T"},{"full_name":"Streicher, Carmen","first_name":"Carmen","last_name":"Streicher","id":"36BCB99C-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Simon","full_name":"Hippenmeyer, Simon","last_name":"Hippenmeyer","id":"37B36620-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2279-1061"}],"day":"20","ddc":["570"],"OA_place":"publisher","oa":1,"OA_type":"gold","article_processing_charge":"Yes","publication_status":"published","acknowledgement":"We thank A.

Instead of inspecting the options\r\nherself, P delegates the information acquisition to a rational and self-interested agent A. After\r\ninspection, A proposes one of the options, and P can accept or reject.\r\nDelegation is a classic setting in economic information design with many prominent applications,\r\nbut the computational problems are only poorly understood. In this paper, we study a natural\r\nonline variant of delegation, in which the agent searches through the options in an online fashion.\r\nFor each option, he has to irrevocably decide if he wants to propose the current option or discard\r\nit, before seeing information on the next option(s). How can we design algorithms for P that\r\napproximate the utility of her best option in hindsight?\r\nWe show that in general P can obtain a Θ(1∕𝑛)-approximation and extend this result to ratios\r\nof Θ(𝑘∕𝑛) in case (1) A has a lookahead of 𝑘 rounds, or (2) A can propose up to 𝑘 different\r\noptions. We provide fine-grained bounds independent of 𝑛 based on three parameters. If the ratio\r\nof maximum and minimum utility for A is bounded by a factor 𝛼, we obtain an Ω(loglog 𝛼∕ log 𝛼)-\r\napproximation algorithm, and we show that this is best possible. Additionally, if P cannot\r\ndistinguish options with the same value for herself, we show that ratios polynomial in 1∕𝛼 cannot\r\nbe avoided. If there are at most 𝛽 different utility values for A, we show a Θ(1∕𝛽)-approximation.\r\nIf the utilities of P and A for each option are related by a factor 𝛾, we obtain an Ω(1∕ log 𝛾)-\r\napproximation, where 𝑂(log log 𝛾∕ log 𝛾) is best possible.","lang":"eng"}],"title":"Delegated online search","publication_identifier":{"issn":["0004-3702"]},"isi":1,"file":[{"access_level":"open_access","content_type":"application/pdf","success":1,"creator":"dernst","date_updated":"2025-01-09T10:45:24Z","file_size":772226,"date_created":"2025-01-09T10:45:24Z","checksum":"f02a56bc7ea88f41fcc68968e4ceddf3","file_name":"2024_ArtificialIntelligence_Braun.pdf","relation":"main_file","file_id":"18806"}],"publication":"Artificial Intelligence","article_type":"original","year":"2024","language":[{"iso":"eng"}],"external_id":{"isi":["001260448100001"],"arxiv":["2203.01084"]},"has_accepted_license":"1","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"type":"journal_article","doi":"10.1016/j.artint.2024.104171","volume":334,"quality_controlled":"1","date_created":"2024-06-30T22:01:05Z","date_updated":"2025-09-08T08:00:42Z","_id":"17188","oa_version":"Published Version","month":"09","scopus_import":"1","publisher":"Elsevier","department":[{"_id":"MoHe"}],"file_date_updated":"2025-01-09T10:45:24Z","corr_author":"1","status":"public","article_number":"104171","arxiv":1,"citation":{"ieee":"P.

However, their internal flows, which can be probed only by helioseismology, are not well understood. We analyse dopplergrams recorded by the Solar Dynamics Observatory satellite to identify and characterize ~23,000 supergranules. We find that the vertical flows peak at a depth of ~10,000 km, and remain invariant over the full range of lateral supergranular scales, contrary to numerical predictions. We also infer that, within the local seismic resolution (≳5,000 km), downflows are ~40% weaker than upflows, indicating an apparent mass-flux imbalance. This may imply that the descending flows also comprise plumes, which maintain the mass balance but are simply too small to be detected by seismic waves. These results challenge the widely used mixing-length description of solar convection."}],"acknowledgement":"We thank F. J. Simons for the codes for computing Slepian functions,\r\nM. Rempel and R.
