This raises the hitherto untested possibility that heterogeneity of the untransformed tumor stroma can actively fuel malignant progression. As biological heterogeneity is inherently difficult to control, we adopted a reductionist approach and let tumor cells invade micro-engineered environments harboring obstacles with precision-controlled geometry. We find that not only the presence of obstacles, but more surprisingly their spatial disorder, causes a drastic shift from a collective to a single-cell mode of invasion – comparable in strength to cadherin loss. Combining live-imaging and perturbation experiments with minimal biophysical modeling, we demonstrate that cell detachments result both from local geometrical constraints and a global integration of spatial disorder over time. We show that different types of microenvironments map onto different universality classes of invasion dynamics - homogeneous substrates follow Kardar–Parisi–Zhang (KPZ) scaling, while disordered ones exhibit exponents consistent with KPZ with quenched disorder (KPZq). Our findings highlight generic physical principles for how the mode of cancer cell invasion depends on environmental heterogeneity, with potential implications to understand tumor evolution in vivo."}],"date_created":"2026-03-11T08:40:06Z","oa":1,"has_accepted_license":"1","OA_place":"repository","title":"Substrate heterogeneity promotes cancer cell dissemination through interface roughening","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","year":"2025","project":[{"_id":"bd91e723-d553-11ed-ba76-fe7eeb2185fd","grant_number":"101071793","name":"Pushing from within: Control of cell shape, integrity and motility by cytoskeletal pushing forces"},{"name":"Motile active matter models of migrating cells and chiral filaments","grant_number":"26360","_id":"34d75525-11ca-11ed-8bc3-89b6307fee9d"}],"publisher":"bioRxiv","ddc":["539","570"],"article_processing_charge":"No","date_published":"2025-09-25T00:00:00Z","author":[{"first_name":"Zuzana","last_name":"Dunajova","id":"4B39F286-F248-11E8-B48F-1D18A9856A87","full_name":"Dunajova, Zuzana"},{"orcid":"0000-0003-1671-393X","first_name":"Saren","last_name":"Tasciyan","full_name":"Tasciyan, Saren","id":"4323B49C-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Majek","id":"3e6d9473-f38e-11ec-8ae0-c4e05a8aa9e1","full_name":"Majek, Juraj","first_name":"Juraj"},{"orcid":"0000-0001-5145-4609","first_name":"Jack","last_name":"Merrin","full_name":"Merrin, Jack","id":"4515C308-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Sahai, Erik","last_name":"Sahai","first_name":"Erik"},{"last_name":"Sixt","full_name":"Sixt, Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","first_name":"Michael K"},{"id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","full_name":"Hannezo, Edouard B","last_name":"Hannezo","first_name":"Edouard B","orcid":"0000-0001-6005-1561"}],"_id":"21427"},{"type":"preprint","date_updated":"2026-05-19T11:20:27Z","abstract":[{"text":"The recent surge in high-quality open-source Generative AI text models (colloquially: LLMs), as well as efficient finetuning techniques, have opened the possibility of creating high-quality personalized models that generate text attuned to a specific individual’s needs and are capable of credibly imitating their writing style by refining an open-source model with that person’s own data. The technology to create such models is accessible to private individuals, and training and running such models can be done cheaply on consumer-grade hardware. While these advancements are a huge gain for usability and privacy, this position paper argues that the practical feasibility of impersonating specific individuals also introduces novel safety risks. For instance, this technology enables the creation of phishing emails\r\nor fraudulent social media accounts, based on small amounts of publicly available text, or by the individuals themselves to escape AI text detection. We further argue that these risks are complementary to—and distinct from—the much-discussed risks of other impersonation attacks such as image, voice, or video deepfakes, and are not adequately addressed by the larger research community, or the current generation of open- and closed-source models.","lang":"eng"}],"date_created":"2026-05-11T08:55:23Z","publication":"arXiv","oa":1,"OA_place":"repository","title":"Position: It's time to act on the risk of efficient personalized text generation","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","OA_type":"green","acknowledgement":"This research was supported by the Scientific Service Units (SSU) of IST Austria through resources\r\nprovided by Scientific Computing (SciComp).

In this article, we study how the main solution concepts, the discounted and undiscounted values, vary when these parameters are perturbed. We focus on the marginal values, introduced by Mills in 1956 in the context of matrix games—that is, the directional derivatives of the value along any fixed perturbation.

This famous\r\nquotation of the brilliant Richard Feynman within a conference talk on \"Simulating physics\r\nwith computers.” is often reverently praised as the origin of the field of quantum computing.\r\nThe idea was to use quantum mechanical systems itself to simulate \"Nature\", which is\r\ninherently quantum mechanical. Now, 43 years later, the theoretical framework of how such\r\na computer can operate has been developed. Two main important concepts for a potential\r\nquantum supremacy, superposition and entanglement, have been exploited to design quantum\r\nalgorithms to significantly speed up certain tasks. Yet, the specific hardware implementation\r\nis still far from being certain, in fact the race between the most promising platforms such as\r\nsuperconducting qubits, bosonic codes, cold atoms, trapped ions, optical computing as well\r\nas spin qubits has recently intensified. If one also includes the most mature applications of\r\nquantum communication technologies, secure quantum key distribution and quantum random\r\nnumber generators, as part of a quantum information technology ecosystem, we are confronted\r\nwith a plethora of different materials, concepts, and also operation frequencies. While\r\nsuperconducting qubits, bosonic codes and spin qubits work in the regime of approximately 5\r\nGHz and are controlled by electrical fields, trapped ions, cold atoms, and optical quantum\r\ncomputing operate with light in the infrared or visible range.\r\nConsequently, a quantum frequency converter or microwave-optic transducer is required\r\nto interface the different frequency domains or establish a long-range network connection\r\nwith suitable telecom fibers. In fact, the combination of different frequency regimes is also\r\nan essential part in our classical modern communication network, where computations are\r\nperformed in electrical circuits and the information exchange over longer distances happens\r\nvia optical fibers. However, the specific challenges specific to building a quantum computer,\r\nalso apply to the development of such a quantum frequency transducer: 1) As we deal with\r\nsingle excitations as the carrier of information, i.e. the smallest possible quantity, the signal\r\ncan easily be corrupted by other noise sources which needs to be avoided by all means. This\r\nis also the reason why microwave quantum computers operate at temperature environments\r\nclose to zero temperature (< 0.1 Kelvin) to avoid corruption by thermal noise. 2) The\r\nfrequency interface generally needs to preserve the phase of the signal as an essential part\r\nof the quantum state. And 3) Quantum signals cannot be copied which would be a typical\r\nstrategy to account for errors in classical computers. And finally, there is a challenge specific to\r\nmicrowave-optic transducers: While quantum computers are operating in one specific frequency\r\ndomain, microwave-optic transducers combine microwave and optical fields in one device.\r\nThis results in the particular challenge that high-energy optical radiation, which is usually\r\nwell-shielded from superconducting microwave quantum processors, are now an essential part\r\nof the device. The concomitant optical radiation in the operating transducer will inevitably\r\nhave a detrimental effect on the superconducting microwave components. Together with the\r\nrequirement of minimal background noise for quantum-limited operation as described above,\r\nv\r\nheating from the absorption of optical photons within the same device where single microwave\r\nexcitations are processed forms a formidable challenge.\r\nThis thesis aims to address this challenge by developing microwave-optic transducers where\r\nthe impact of optical absorption on superconducting circuits in general and superconducting\r\nqubits specifically can be mitigated. In our first approach, we developed a compact device\r\nwith optimized interaction strengths between the different frequency domains. This minimizes\r\nthe optical powers used for transducer operation and thus the optical absorption heating. This\r\nwork was - to the best of our knowledge - the first comprehensive noise study, in an integrated\r\nmicrowave-optic transducer. Unfortunately, we saw that the optical absorption heating added\r\nnoise way above a single excitation. Consequently, a potential quantum signal would have\r\nbeen buried in the noise, added by the transduction.\r\nBuilding on this insight, we utilized a three-dimensional microwave-optic transducer instead\r\nof an integrated device. The larger heat capacity of the macroscopic device with a size\r\nof a few millimeters can absorb a larger fraction of the optical heating before it increases\r\nthe temperature of the device. This allowed us to interface the transducer directly with a\r\nsuperconducting qubit to readout the qubit state in a novel all-optical manner. We showed\r\nthat the microwave-optic transducer can be operated in a regime in which optical fields don’t\r\nharm the sensitive qubit. This is an important prerequisite for the operation of microwave-optic\r\ntransducers in conjunction with microwave quantum processors and brings the integration and\r\nseamless orchestration of different frequency components in a quantum network a step closer.\r\n"}],"date_created":"2025-01-24T10:28:39Z","supervisor":[{"first_name":"Johannes M","orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","last_name":"Fink"}],"publication_identifier":{"issn":["2663-337X"]},"acknowledged_ssus":[{"_id":"SSU"},{"_id":"M-Shop"},{"_id":"NanoFab"}],"oa_version":"Published Version","language":[{"iso":"eng"}],"related_material":{"record":[{"id":"6609","relation":"part_of_dissertation","status":"public"},{"id":"8529","relation":"part_of_dissertation","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"18953"},{"status":"public","relation":"part_of_dissertation","id":"10924"},{"relation":"part_of_dissertation","id":"9114","status":"public"},{"id":"13200","relation":"part_of_dissertation","status":"public"}]},"corr_author":"1","month":"01","department":[{"_id":"JoFi"},{"_id":"GradSch"}],"publication_status":"published","day":"24","doi":"10.15479/at:ista:18871","ec_funded":1,"acknowledgement":"This work was supported by the European Research Council under grant agreement no. 758053\r\n(ERC StG QUNNECT) and the European Union’s Horizon 2020 research, innovation program\r\nunder grant agreement no. 899354 (FETopen SuperQuLAN) and the Austrian Science Fund\r\n(FWF) through BeyondC (F7105).

Combining multicellular patch-clamp recording with expansion-based superresolution microscopy and full-scale modeling, we determined the cellular and microcircuit properties of the human hippocampal CA3 region, a fundamental circuit for memory storage. In contrast to neocortical networks, human hippocampal CA3 displayed sparse connectivity, providing a circuit architecture that maximizes associational power. Human synapses showed unique reliability, high precision, and long integration times, exhibiting both species- and circuit-specific properties. Together with expanded neuronal numbers, these circuit characteristics greatly enhanced the memory storage capacity of CA3.

Among these, Ag8SnSe6 stands out for its exceptionally low sound velocity and thermal conductivity. However, the inherent poor electrical conductivity and suboptimal thermoelectric properties of Ag8SnSe6 necessitate further improvement. Here, a novel approach is initiated to enhance the thermoelectric properties of Ag8SnSe6 by combining low-dimensionalization with intrinsic doping. For the first time, this work successfully synthesizes single-phase Ag8SnSe6 nanocrystals, ≈10 nm in size, with the correct phase and composition using a robust and reliable colloidal method. This approach represents a significant improvement over previous reports on this material. Reducing the crystal domains of Ag8SnSe6 to the nanoscale induces quantum confinement effects, increasing the density of states near the Fermi surface. It also introduces additional grain boundaries, which lower the lattice thermal conductivity and simplify structural design. Moreover, incorporating small amounts of Sn nanopowder into the Ag8SnSe6 nanocrystals before consolidation further enhances the thermoelectric performance. Sn acts as a donor dopant, increasing the electronic concentration while at the same time improving their mobility by reducing interface barriers, thus significantly improving the material transport properties. Additionally, the presence of Sn leads to the formation of point defects, dislocations, and secondary phases, which increase phonon scattering and further reduce the thermal conductivity. Through this synergistic optimization, the figure of merit  shows a significant increase across a wide temperature range. Overall, a strategy is presented for the controlled preparation of Ag8SnSe6 nanocrystals, the decoupling of their electrical and thermal transport, and the practical application of this material to thermoelectric single-leg modules.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Low-dimensional structure modulation in Ag8SnSe6 for enhanced thermoelectric performance","OA_type":"closed access","article_type":"original","scopus_import":"1","acknowledgement":"X.Z. and M.L. contributed equally to this work.

This thesis summarizes three projects related to computations in TDA.\r\n\r\nThe first one establishes a variant of TDA for chromatic point sets, where each point is given a color. For example, we are given positions of cells within a tumor microenvironment, and color the cancerous cells red, and the immune cells blue.\r\n\r\nThe aim is then to give a quantitative description of how the two or more sets of points spatially interact. Building on image, kernel and cokernel variants of persistent homology, we suggest six-packs of persistent diagrams as such a descriptor.\r\n\r\nWe describe a construction of a chromatic alpha complex, which enables  efficient computation of several variants of the six-packs. We give topological descriptions of natural subcomplexes of the chromatic alpha complex, and show that the radii of the simplices form a discrete Morse function. Finally, we provide an implementation of the presented chromatic TDA pipeline.\r\n\r\nThe second part aims to translate a powerful tool of sheaf theory to elementary terms using labeled matrices. The goal is to enable their use in computational settings. We show that derived categories of sheaves over finite posets have, up to isomorphism, unique objects---minimal injective resolutions---and give a concrete algorithm to compute them. We further describe simple algorithms to compute derived pushforwards and pullbacks for monotonic maps, and their proper variants for inclusions, and demonstrate their tractability by providing an implementation. Finally, we suggest a discrete definition of microsupport and show desirable properties inspired by discrete Morse theory.\r\n\r\nIn the last part, we present a collection of observations about collapses. We give a characterization of collapsibility in terms of unitriangular submatrices of the boundary matrix, a cotree-tree decomposition, and the optimal solution to a variant of the Procrustes problem. We establish relation between dual collapses and relative Morse theory and pose several open questions. Finally, focusing on complexes embedded in the three-dimensional Euclidean space, we describe a relation between the collapsibility and the triviality of a polygonal knot.","lang":"eng"}],"has_accepted_license":"1","oa":1,"keyword":["topological data analysis","chromatic point set","alpha complex","persistent homology","six pack","sheaf","microlocal discrete Morse","injective resolution","collapse","knot","discrete Morse theory"],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","title":"Structures and computations in topological data analysis","OA_place":"publisher","acknowledgement":"The research presented in this thesis was funded with the Wittgenstein Prize,\r\nAustrian Science Fund (FWF), grant no.

Mathematically, they represent a fundamental class of transformations and symmetries. Unlike spatial displacements, rotational transformations in three-dimensional space  are non-commutative: the result of applying a sequence of rotations depends on the order of these operations. This feature makes the emergent physics that involves rotations rather intricate, but instrumental for studies of highly-interconnected many-body systems. In the presence of an environment, rotational properties of an object change, due to the interaction with particles of the environment. Owing to the complexity of this interaction, it can be engineered to exhibit certain properties of interest. In this Thesis, we examine several scenarios of how the rotational behavior of an impurity can be modified by interactions with its environment."}],"date_created":"2025-02-18T01:41:27Z","supervisor":[{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","first_name":"Mikhail","orcid":"0000-0002-6990-7802"}],"publication_identifier":{"issn":["2663-337X"]},"file_date_updated":"2025-02-18T14:25:59Z","type":"dissertation","date_updated":"2026-04-16T12:20:38Z","OA_place":"publisher","title":"Emergent physics of rotating quantum impurities in many-body environments","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","has_accepted_license":"1","oa":1},{"scopus_import":"1","acknowledgement":"The authors thank the International Space Science Institute for sponsoring the ISSI team: ‘Star Formation within rapidly evolving galaxies’ where many ideas discussed in this article have been brainstormed.

The lensed clumps present magnifications ranging between μ = 1.8 and μ = 300. We perform simultaneous size-photometry estimates in 20 JWST/NIRCam median and broad-band filters from 0.7 to 5 μm.\r\nSpectral energy distribution (SED) fitting analyses enable us to recover the physical properties of the clumps. The majority of the clumps are spatially resolved and have effective radii in the range Reff = 10–700 pc. We restrict this first study to the 1751 post-reionization era clumps with redshift < 5.5. We find a significant evolution of the average clump ages, star formation rates (SFRs), SFR surface densities, and metallicity with increasing redshift, while median stellar mass and stellar mass surface densities are similar in the probed redshift range. We observe a strong correlation between the clump properties and the properties of their host galaxies, with more massive galaxies hosting more massive and older clumps. We find that clumps closer to their host galactic centre are on average more massive, while their ages do not show clear sign of migration. We find that clumps at cosmic noon sample the upper-mass end of the mass function to higher masses than at z > 3, reflecting the rapid increase towards the peak of the cosmic star formation history. We conclude that the results achieved over the studied redshift range are in agreement with expectation of in situ clump formation scenario from large-scale disc fragmentation.

This leads to clear design principles that often result in high assembly yield, but it is not a scalable approach—at some point, one must grapple with “reusing” building blocks, which lowers the degree of addressability and may cause a multitude of off-target structures to form, complicating the design process. Here, we solve a key obstacle preventing robust inverse design in the “semiaddressable regime” by developing a highly efficient algorithm that enumerates all structures that can be formed from a given set of building blocks. By combining this with established partition-function-based yield calculations, we show that it is almost always possible to find economical semiaddressable designs where the entropic gain from reusing building blocks outweighs the presence of off-target structures and even increases the yield of the target. Thus, not only does our enumeration algorithm enable robust and scalable inverse design in the semiaddressable regime, our results demonstrate that it is possible to operate in this regime while maintaining the level of control often associated with full addressability."}],"language":[{"iso":"eng"}],"quality_controlled":"1","oa_version":"Preprint","arxiv":1,"publication_status":"published","department":[{"_id":"CaGo"},{"_id":"GradSch"}],"day":"07","doi":"10.1103/PhysRevLett.134.058204","related_material":{"link":[{"url":"https://github.com/mxhbl/Roly.jl","relation":"software"}]},"corr_author":"1","month":"02","scopus_import":"1","acknowledgement":"We thank Daichi Hayakawa, Thomas E.

Studies in zebrafish have identified a remarkable morphological\r\nleft-right asymmetry in the dorsal habenula (zebrafish equivalent of mammalian\r\nMHb)-to-interpeduncular nucleus (IPN) pathway and its left-side specific role in\r\nmodulating fear responses. However, there is little evidence for structural or\r\nfunctional lateralization in the mammalian MHb-IPN pathway.\r\nHere, I investigated the synaptic properties of the left and right MHb\r\nafferents to the IPN in mice and addressed whether these synaptic connections\r\nselectively influence the expression of conditioned fear in mice. My findings reveal\r\nthat each individual IPN neuron receives inputs from both left and right MHb.\r\nElectrophysiological recordings from the same postsynaptic IPN neurons\r\ndemonstrate that the left MHb-originating synapses exhibit lower release\r\nprobability and higher 𝛾-aminobutyric acid type B receptor (GABABR)-mediated\r\npotentiation compared to the right MHb-originating synapses. Interestingly,\r\nchemogenetic inhibition of cholinergic neurons in the left but not the right MHb\r\nsignificantly attenuated cue-dependent fear recall. Furthermore, conditional\r\ndeletion of GABABR in the left MHb interfered with the recall of cued fear memory,\r\nwhereas that in the right MHb neurons spared fear memory expression.\r\nCollectively, I demonstrate a functional asymmetry of the MHb in mice,\r\nrevealing a predominant role for GABABR-mediated signaling in the left MHb-IPN\r\npathway in the modulation of fear memories.

Within this taxon, Brine shrimp of the genus Artemia, a\r\nbranchiopod crustacean, are well suited for such explorations, as they have both highly\r\ndimorphic traits and closely related sexual and asexual species. Although brine shrimp are\r\nknown to have ZW sex chromosomes (Bowen, 1963; Parraguez et al., 2009), the sex\r\nchromosomes are still not well characterized at the genomic level, the sex-determination gene\r\nis unknown, and it is still unclear whether the same sex chromosomes as shared by the\r\ndifferent species.\r\nThe first part of this thesis was to characterize the Z and W chromosomes in Artemia\r\nusing an array of methods, from generating multiple chromosome and contig level genome\r\nassemblies to identifying W-linked scaffolds and transcripts in multiple species using k-mer\r\nbased approaches.\r\nThe second part tackles the conservation of the cell type specific regulatory pathways\r\nin the female reproductive system between Artemia and Drosophila, and the expression of the\r\nZ-specific region throughout meiosis using single-nucleus RNA-seq data. Our results show\r\nthat germline cells lack dosage compensation, with a subset of cells showing evidence of\r\nextreme repression of the Z chromosome.\r\nWith multiple sexual species and several asexual lineages of parthenogenetic females\r\nthat produce rare males at low frequencies, Brine shrimp present the perfect opportunity to\r\nexplore the transition to asexuality and shed light on the prerequisites and repercussions of\r\nthe form of modified meiosis maintaining the asexual lineages. The last chapter is an\r\ninvestigation of the molecular pathways involved in asexual reproduction in Artemia using\r\nnewly generated single nucleus RNAseq and WGS data and previously published data.

In contrast to classical rotations, quantum mechanics unveils the SO(3) symmetry group structure, manifesting in phenomena without classical counterparts, from angular momentum quantization to non-trivial addition of angular momenta.\r\nWhile most studies of topological physics have focused on two-band systems, the SO(3) symmetry group of quantum rotors offers an inherently more complex platform with unprecedented possibilities for exploring topological phenomena. Despite their ubiquity in nature– from molecules to nanorotors– their potential for hosting topological phases has remained largely unexamined.\r\nIn this thesis, we mainly focus on periodically driven linear molecules as a prototype for studying topological phenomena in quantum rotors. Recent technological advances in coherent control of molecules, particularly through precisely shaped laser pulses, have made it possible to investigate linear rotors in the context of topology. While planar rotors have received some attention in recent years, threedimensional rotors–particularly linear molecules–harbor substantially richer topological phenomena due to their non-abelian nature and their additional angular degrees of freedom. We demonstrate that these systems can host novel edge states and topological features fundamentally impossible in planar systems.\r\nWe begin by establishing a theoretical bridge between periodically kicked rotors and \"crystalline\" lattices in angular momentum space. Using non-interacting linear molecules as our primary example, we show how quantum interference and revival patterns lead to the possibility to simulate band models with arbitrary number of bands N. While our framework applies to various quantum rotors, including nanorotors and kicked Bose-Einstein condensates, linear\r\nmolecules provide an ideal experimental platform due to their abovementioned precise controllability.\r\nThe core of this work examines adiabatic dynamics of 3D quantum rotors, establishing a geometric framework based on the Euler class to characterize its non-abelian topology. The non-Hermitian nature of the system enables novel braiding behaviors and topological transitions impossible in static systems, leading to an anomalous Dirac string phase with edge states in each gap, even though the Berry phases are all zero. These features can be directly observed through\r\nmolecular alignment and rotational level populations.\r\nThese findings establish quantum rotors as an alternative platform for studying multi-band topological physics, while suggesting practical implementations for quantum computation where topological protection could offer natural resilience against decoherence. The rich structure of three-dimensional rotation groups, combined with the tunability of topological features through driving parameters, makes this platform particularly valuable for exploring fundamental\r\nphysics and developing quantum technologies.","lang":"eng"}],"language":[{"iso":"eng"}],"oa_version":"Published Version","doi":"10.15479/AT-ISTA-19393","day":"13","department":[{"_id":"GradSch"},{"_id":"MiLe"}],"publication_status":"published","corr_author":"1","month":"03","related_material":{"record":[{"relation":"part_of_dissertation","id":"14851","status":"public"},{"relation":"part_of_dissertation","id":"12788","status":"public"},{"status":"public","id":"19425","relation":"part_of_dissertation"},{"id":"9903","relation":"part_of_dissertation","status":"public"},{"id":"15004","relation":"part_of_dissertation","status":"public"}]},"file":[{"access_level":"open_access","success":1,"checksum":"d3ab25782c7ea38ce9910e57d25f6733","relation":"main_file","content_type":"application/pdf","file_name":"thesis_final.pdf","date_created":"2025-03-12T12:56:46Z","file_id":"19394","creator":"vkarle","file_size":10625143,"date_updated":"2025-03-12T12:56:46Z"},{"date_updated":"2025-03-20T08:02:35Z","creator":"vkarle","file_size":23119202,"date_created":"2025-03-13T13:15:10Z","file_id":"19400","file_name":"thesis.zip","content_type":"application/zip","checksum":"3ccfb0aeba4d860d71e18347913034e4","relation":"source_file","access_level":"closed"}],"citation":{"apa":"Karle, V.
