To examine the role of GCs in spatial coding, we measured excitatory postsynaptic potentials (EPSPs) and action potentials (APs) in head-fixed mice running on a linear belt. Intracellular recording from morphologically identified GCs revealed that most cells were active, but activity level varied over a wide range. Whereas only ∼5% of GCs showed spatially tuned spiking, ∼50% received spatially tuned input. Thus, the GC population broadly encodes spatial information, but only a subset relays this information to the CA3 network. Fourier analysis indicated that GCs received conjunctive place-grid-like synaptic input, suggesting code conversion in single neurons. GC firing was correlated with dendritic complexity and intrinsic excitability, but not extrinsic excitatory input or dendritic cable properties. Thus, functional maturation may control input-output transformation and spatial code conversion.","lang":"eng"}],"external_id":{"isi":["000579698700009"],"pmid":["32763145"]},"status":"public","has_accepted_license":"1","date_created":"2020-08-14T09:36:05Z","publication":"Neuron","scopus_import":"1","oa_version":"Published Version","corr_author":"1","type":"journal_article","ec_funded":1,"article_type":"original","citation":{"chicago":"Zhang, Xiaomin, Alois Schlögl, and Peter M Jonas. “Selective Routing of Spatial Information Flow from Input to Output in Hippocampal Granule Cells.” <i>Neuron</i>.

Lossy compression of data is an intriguing solution, but comes with its own drawbacks, such as potential signal loss, and the need for careful optimization of the compression ratio. In this work, we focus on a setting where this problem is especially acute: compressive sensing frameworks for interferometry and medical imaging. We ask the following question: can the precision of the data representation be lowered for all inputs, with recovery guarantees and practical performance Our first contribution is a theoretical analysis of the normalized Iterative Hard Thresholding (IHT) algorithm when all input data, meaning both the measurement matrix and the observation vector are quantized aggressively. We present a variant of low precision normalized IHT that, under mild conditions, can still provide recovery guarantees. The second contribution is the application of our quantization framework to radio astronomy and magnetic resonance imaging. We show that lowering the precision of the data can significantly accelerate image recovery. We evaluate our approach on telescope data and samples of brain images using CPU and FPGA implementations achieving up to a 9x speedup with negligible loss of recovery quality.","lang":"eng"}],"status":"public","external_id":{"arxiv":["1802.04907"],"isi":["000562044500001"]},"intvolume":"        68","date_updated":"2025-07-10T11:55:10Z","arxiv":1,"article_processing_charge":"No","publication_identifier":{"eissn":["1941-0476"],"issn":["1053-587X"]},"day":"20","department":[{"_id":"DaAl"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"title":"Compressive sensing using iterative hard thresholding with low precision data representation: Theory and applications","date_published":"2020-07-20T00:00:00Z","_id":"8268","quality_controlled":"1","isi":1,"acknowledgement":"The authors would like to thank Dr. Michiel Brentjens at the Netherlands Institute for Radio Astronomy (ASTRON) for providing radio interferometer data and Dr. Josip Marjanovic and Dr. Franciszek Hennel at the Magnetic Resonance Technology of ETH Zurich for providing their insights on the experiments.

Stochastic games are standard models in control, verification, and synthesis of stochastic reactive systems that exhibit both randomness as well as angelic and demonic non-determinism. Lexicographic order allows to consider multiple objectives with a strict preference order over the satisfaction of the objectives. To the best of our knowledge, stochastic games with lexicographic objectives have not been studied before. We establish determinacy of such games and present strategy and computational complexity results. For strategy complexity, we show that lexicographically optimal strategies exist that are deterministic and memory is only required to remember the already satisfied and violated objectives. For a constant number of objectives, we show that the relevant decision problem is in   NP∩coNP , matching the current known bound for single objectives; and in general the decision problem is   PSPACE -hard and can be solved in   NEXPTIME∩coNEXPTIME . We present an algorithm that computes the lexicographically optimal strategies via a reduction to computation of optimal strategies in a sequence of single-objectives games. We have implemented our algorithm and report experimental results on various case studies.","lang":"eng"}],"language":[{"iso":"eng"}],"citation":{"apa":"Chatterjee, K., Katoen, J.

The mechanism of coupling between ion or electron transfer and proton translocation in this large protein family is unknown. Here, we present the structure of the Mrp complex from Anoxybacillus flavithermus solved by cryo-EM at 3.0 Å resolution. It is a dimer of seven-subunit protomers with 50 trans-membrane helices each. Surface charge distribution within each monomer is remarkably asymmetric, revealing probable proton and sodium translocation pathways. On the basis of the structure we propose a mechanism where the coupling between sodium and proton translocation is facilitated by a series of electrostatic interactions between a cation and key charged residues. This mechanism is likely to be applicable to the entire family of redox proton pumps, where electron transfer to substrates replaces cation movements."}],"type":"journal_article","scopus_import":"1","publication":"eLife","oa_version":"Published Version","date_created":"2020-08-24T06:24:04Z","month":"07","volume":9,"related_material":{"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/mystery-of-giant-proton-pump-solved/"}],"record":[{"id":"8353","status":"public","relation":"dissertation_contains"}]},"file_date_updated":"2020-08-24T13:31:53Z","publication_status":"published","year":"2020","pmid":1,"author":[{"orcid":"0000-0003-0493-3775","first_name":"Julia","last_name":"Steiner","full_name":"Steiner, Julia","id":"3BB67EB0-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Sazanov, Leonid A","id":"338D39FE-F248-11E8-B48F-1D18A9856A87","last_name":"Sazanov","orcid":"0000-0002-0977-7989","first_name":"Leonid A"}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"LifeSc"}],"publisher":"eLife Sciences Publications","isi":1,"file":[{"file_size":7320493,"success":1,"checksum":"b3656d14d5ddbb9d26e3074eea2d0c15","file_name":"2020_eLife_Steiner.pdf","file_id":"8289","date_updated":"2020-08-24T13:31:53Z","creator":"cziletti","relation":"main_file","access_level":"open_access","date_created":"2020-08-24T13:31:53Z","content_type":"application/pdf"}],"doi":"10.7554/eLife.59407","acknowledgement":"This research was supported by the Scientific Service Units (SSU) of IST Austria through resources provided by the Electron Microscopy Facility (EMF), the Life Science Facility (LSF) and the IST high-performance computing cluster.

This task is known to be computationally expensive for linear hybrid systems. Reachability analysis works by iteratively applying continuous and discrete post operators to compute states reachable according to continuous and discrete dynamics, respectively. In this paper, we enhance both of these operators and make sure that most of the involved computations are performed in low-dimensional state space. In particular, we improve the continuous-post operator by performing computations in high-dimensional state space only for time intervals relevant for the subsequent application of the discrete-post operator. Furthermore, the new discrete-post operator performs low-dimensional computations by leveraging the structure of the guard and assignment of a considered transition. We illustrate the potential of our approach on a number of challenging benchmarks.","lang":"eng"}],"status":"public","has_accepted_license":"1","external_id":{"arxiv":["1905.02458"],"isi":["000587712700072"]},"project":[{"call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23"},{"grant_number":"Z00312","call_identifier":"FWF","name":"Synaptic communication in neuronal microcircuits","_id":"25C5A090-B435-11E9-9278-68D0E5697425"},{"grant_number":"754411","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"date_updated":"2026-04-03T09:32:00Z","arxiv":1,"ddc":["000"],"author":[{"full_name":"Bogomolov, Sergiy","last_name":"Bogomolov","first_name":"Sergiy"},{"full_name":"Forets, Marcelo","first_name":"Marcelo","last_name":"Forets"},{"last_name":"Frehse","first_name":"Goran","full_name":"Frehse, Goran"},{"full_name":"Potomkin, Kostiantyn","last_name":"Potomkin","first_name":"Kostiantyn"},{"id":"3A2F4DCE-F248-11E8-B48F-1D18A9856A87","full_name":"Schilling, Christian","last_name":"Schilling","first_name":"Christian","orcid":"0000-0003-3658-1065"}],"related_material":{"record":[{"id":"8790","status":"public","relation":"later_version"}]},"month":"10","year":"2020","publication_status":"published","file_date_updated":"2020-08-24T12:53:15Z","date_published":"2020-10-01T00:00:00Z","_id":"8287","quality_controlled":"1","file":[{"access_level":"open_access","creator":"cschilli","relation":"main_file","date_created":"2020-08-24T12:53:15Z","content_type":"application/pdf","file_size":696384,"file_name":"2020EMSOFT.pdf","file_id":"8288","date_updated":"2020-08-24T12:53:15Z","checksum":"d19e97d0f8a3a441dc078ec812297d75","success":1}],"isi":1,"conference":{"name":"EMSOFT: Embedded Software","start_date":"2020-09-20","location":"Virtual ","end_date":"2020-09-25"},"article_processing_charge":"No","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"day":"01","keyword":["reachability","hybrid systems","decomposition"],"department":[{"_id":"ToHe"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","oa":1,"title":"Reachability analysis of linear hybrid systems via block decomposition"},{"author":[{"last_name":"Hauschild","first_name":"Robert","orcid":"0000-0001-9843-3522","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","full_name":"Hauschild, Robert"}],"tmp":{"name":"The 3-Clause BSD License","short":"3-Clause BSD","legal_code_url":"https://opensource.org/licenses/BSD-3-Clause"},"license":"https://opensource.org/licenses/BSD-3-Clause","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file_date_updated":"2020-09-08T14:26:33Z","oa":1,"title":"RGtracker","day":"10","department":[{"_id":"Bio"}],"month":"09","date_created":"2020-08-25T12:52:48Z","type":"software","corr_author":"1","abstract":[{"lang":"eng","text":"Automated root growth analysis and tracking of root tips.

In this work, we achieve the best of both worlds by proposing a novel abstractions called the finality gadget. A finality gadget allows for transactions to always optimistically commit but informs the clients that these transactions might be unsafe. As a result, a blockchain can execute transactions optimistically and only commit them after they have been sufficiently and provably audited. In\r\nthis work, we formally model the finality gadget abstraction, prove that it is impossible to solve it deterministically in full asynchrony (even though it is stronger than consensus) and provide a partially synchronous protocol which is currently securing a major blockchain. This way we show that the protocol designer can decouple safety and liveness in order to speed up recovery from failures. We believe that there can be other types of finality gadgets that provide weaker safety (e.g., probabilistic) in order to gain more efficiency and this can depend on the probability that the network is not in synchrony.","lang":"eng"}],"doi":"10.48550/arXiv.2007.01560","extern":"1","arxiv":1,"date_updated":"2025-06-26T11:27:41Z"},{"article_processing_charge":"No","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"title":"Stability of mobility edges in disordered interacting systems","day":"26","department":[{"_id":"MaSe"}],"_id":"8308","quality_controlled":"1","date_published":"2020-08-26T00:00:00Z","article_number":"060202(R)","file":[{"access_level":"open_access","creator":"mserbyn","relation":"main_file","date_created":"2020-08-26T19:28:55Z","content_type":"application/pdf","file_size":488825,"file_id":"8309","file_name":"PhysRevB.102.060202.pdf","date_updated":"2020-08-26T19:28:55Z","success":1,"checksum":"716442fa7861323fcc80b93718ca009c"},{"file_size":711405,"success":1,"checksum":"be0abdc8f60fe065ea6dc92e08487122","date_updated":"2020-08-26T19:29:00Z","file_id":"8310","file_name":"Supplementary-mbme.pdf","relation":"main_file","creator":"mserbyn","access_level":"open_access","date_created":"2020-08-26T19:29:00Z","content_type":"application/pdf"}],"doi":"10.1103/physrevb.102.060202","acknowledgement":"Acknowledgments.

The breakdown of thermalization may be complete, when all eigenstates in the many-body spectrum become localized, or partial, when the so-called many-body mobility edge separates localized and delocalized parts of the spectrum. Previously, De Roeck et al. [Phys. Rev. B 93, 014203 (2016)] suggested a possible instability of the many-body mobility edge in energy density. The local ergodic regions—so-called “bubbles”—resonantly spread throughout the system, leading to delocalization. In order to study such instability mechanism, in this work we design a model featuring many-body mobility edge in particle density: the states at small particle density are localized, while increasing the density of particles leads to delocalization. Using numerical simulations with matrix product states, we demonstrate the stability of many-body localization with respect to small bubbles in large dilute systems for experimentally relevant timescales. In addition, we demonstrate that processes where the bubble spreads are favored over processes that lead to resonant tunneling, suggesting a possible mechanism behind the observed stability of many-body mobility edge. We conclude by proposing experiments to probe particle density mobility edge in the Bose-Hubbard model."}],"status":"public","has_accepted_license":"1","external_id":{"isi":["000562628300001"],"arxiv":["2005.02999"]},"article_type":"original","ec_funded":1,"citation":{"ista":"Brighi P, Abanin DA, Serbyn M. 2020.

We also determined cryo-EM structures of major and minor native states of the complex, differing in the position of the peripheral arm. Crystal structures show that binding of quinone-like compounds (but not of NADH) leads to a related global conformational change, accompanied by local re-arrangements propagating from the quinone site to the nearest proton channel. Normal mode and molecular dynamics analyses indicate that these are likely to represent the first steps in the proton translocation mechanism.

For probabilistic programs the notion is naturally extended to expected sensitivity. A previous approach develops a relational program logic framework for proving expected sensitivity of probabilistic while loops, where the number of iterations is fixed and bounded. In this work, we consider probabilistic while loops where the number of iterations is not fixed, but randomized and depends on the initial input values. We present a sound approach for proving expected sensitivity of such programs. Our sound approach is martingale-based and can be automated through existing martingale-synthesis algorithms. Furthermore, our approach is compositional for sequential composition of while loops under a mild side condition. We demonstrate the effectiveness of our approach on several classical examples from Gambler's Ruin, stochastic hybrid systems and stochastic gradient descent. We also present experimental results showing that our automated approach can handle various probabilistic programs in the literature.","lang":"eng"}],"project":[{"grant_number":"S11407","_id":"25863FF4-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Game Theory"}],"intvolume":"         4","ddc":["004"],"arxiv":1,"date_updated":"2025-04-15T06:30:10Z"},{"acknowledgement":"We thank Andrea Sportiello for sharing his insights on perturbative regimes of the Abelian sandpile model which was the starting point of our work.

Thus we made a step towards understanding the phenomena of the identity in the sandpile group for planar domains where solitons appear according to experiments.

This is due to the sheer number of possible interleavings of a concurrent program, all of which have to be tracked and accounted for in a formal proof. Inventing an inductive invariant that captures all interleavings of a low-level implementation is theoretically possible, but practically intractable. We develop a refinement-based verification framework that provides mechanisms to simplify proof construction by decomposing the verification task into smaller subtasks.\r\n\r\nIn a first line of work, we present a foundation for refinement reasoning over structured concurrent programs. We introduce layered concurrent programs as a compact notation to represent multi-layer refinement proofs. A layered concurrent program specifies a sequence of connected concurrent programs, from most concrete to most abstract, such that common parts of different programs are written exactly once. Each program in this sequence is expressed as structured concurrent program, i.e., a program over (potentially recursive) procedures, imperative control flow, gated atomic actions, structured parallelism, and asynchronous concurrency. This is in contrast to existing refinement-based verifiers, which represent concurrent systems as flat transition relations. We present a powerful refinement proof rule that decomposes refinement checking over structured programs into modular verification conditions. Refinement checking is supported by a new form of modular, parameterized invariants, called yield invariants, and a linear permission system to enhance local reasoning.\r\n\r\nIn a second line of work, we present two new reduction-based program transformations that target asynchronous programs. These transformations reduce the number of interleavings that need to be considered, thus reducing the complexity of invariants. Synchronization simplifies the verification of asynchronous programs by introducing the fiction, for proof purposes, that asynchronous operations complete synchronously. Synchronization summarizes an asynchronous computation as immediate atomic effect. Inductive sequentialization establishes sequential reductions that captures every behavior of the original program up to reordering of coarse-grained commutative actions. A sequential reduction of a concurrent program is easy to reason about since it corresponds to a simple execution of the program in an idealized synchronous environment, where processes act in a fixed order and at the same speed.\r\n\r\nOur approach is implemented the CIVL verifier, which has been successfully used for the verification of several complex concurrent programs. In our methodology, the overall correctness of a program is established piecemeal by focusing on the invariant required for each refinement step separately. While the programmer does the creative work of specifying the chain of programs and the inductive invariant justifying each link in the chain, the tool automatically constructs the verification conditions underlying each refinement step.","lang":"eng"}],"has_accepted_license":"1","status":"public","citation":{"chicago":"Kragl, Bernhard. “Verifying Concurrent Programs: Refinement, Synchronization, Sequentialization.” Institute of Science and Technology Austria, 2020. <a href=\"https://doi.org/10.15479/AT:ISTA:8332\">https://doi.org/10.15479/AT:ISTA:8332</a>.","short":"B.

Although their Histidine Kinase receptors are substantially localised to the endoplasmic reticulum, cellular sites of cytokinin perception and importance of spatially heterogeneous cytokinin distribution continue to be debated. Here we show that cytokinin perception by plasma membrane receptors is an effective additional path for cytokinin response. Readout from a Two Component Signalling cytokinin-specific reporter (TCSn::GFP) closely matches intracellular cytokinin content in roots, yet we also find cytokinins in extracellular fluid, potentially enabling action at the cell surface. Cytokinins covalently linked to beads that could not pass the plasma membrane increased expression of both TCSn::GFP and Cytokinin Response Factors. Super-resolution microscopy of GFP-labelled receptors and diminished TCSn::GFP response to immobilised cytokinins in cytokinin receptor mutants, further indicate that receptors can function at the cell surface. We argue that dual intracellular and surface locations may augment flexibility of cytokinin responses.","lang":"eng"}],"status":"public","external_id":{"isi":["000567931000001"],"pmid":["32855409"]},"has_accepted_license":"1","scopus_import":"1","date_created":"2020-09-06T22:01:13Z","oa_version":"Published Version","publication":"Nature Communications","type":"journal_article","ec_funded":1,"article_type":"original","citation":{"chicago":"Antoniadi, Ioanna, Ondřej Novák, Zuzana Gelová, Alexander J Johnson, Ondřej Plíhal, Radim Simerský, Václav Mik, et al. “Cell-Surface Receptors Enable Perception of Extracellular Cytokinins.” <i>Nature Communications</i>.

The literature contains a wealth of useful theorems about the behavior of discrete Gaussians under convolutions and related operations. Yet despite their structural similarities, most of these theorems are formally incomparable, and their proofs tend to be monolithic and written nearly “from scratch,” making them unnecessarily hard to verify, understand, and extend.\r\nIn this work we present a modular framework for analyzing linear operations on discrete Gaussian distributions. The framework abstracts away the particulars of Gaussians, and usually reduces proofs to the choice of appropriate linear transformations and elementary linear algebra. To showcase the approach, we establish several general properties of discrete Gaussians, and show how to obtain all prior convolution theorems (along with some new ones) as straightforward corollaries. As another application, we describe a self-reduction for Learning With Errors (LWE) that uses a fixed number of samples to generate an unlimited number of additional ones (having somewhat larger error). The distinguishing features of our reduction are its simple analysis in our framework, and its exclusive use of discrete Gaussians without any loss in parameters relative to a prior mixed discrete-and-continuous approach.\r\nAs a contribution of independent interest, for subgaussian random matrices we prove a singular value concentration bound with explicitly stated constants, and we give tighter heuristics for specific distributions that are commonly used for generating lattice trapdoors. These bounds yield improvements in the concrete bit-security estimates for trapdoor lattice cryptosystems.","lang":"eng"}],"external_id":{"isi":["001299210200021"]},"status":"public","project":[{"_id":"258AA5B2-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Teaching Old Crypto New Tricks","grant_number":"682815"}],"intvolume":"     12110","date_updated":"2026-04-16T09:32:27Z"},{"_id":"8341","date_published":"2020-09-08T00:00:00Z","supervisor":[{"full_name":"Loose, Martin","id":"462D4284-F248-11E8-B48F-1D18A9856A87","last_name":"Loose","orcid":"0000-0001-7309-9724","first_name":"Martin"}],"degree_awarded":"PhD","publisher":"Institute of Science and Technology Austria","acknowledgement":"My thanks goes to the Loose lab members, BioImaging, Life Science and Nanofabrication Facilities and the wonderful international community at IST for sharing this experience with me.","file":[{"access_level":"closed","relation":"source_file","creator":"dernst","date_created":"2020-09-08T09:00:29Z","content_type":"application/x-zip-compressed","file_size":65246782,"date_updated":"2021-09-16T12:49:12Z","file_name":"2020_Urban_Bezeljak_Thesis_TeX.zip","file_id":"8342","checksum":"70871b335a595252a66c6bbf0824fb02"},{"date_updated":"2021-09-16T12:49:12Z","file_id":"8343","file_name":"2020_Urban_Bezeljak_Thesis.pdf","checksum":"59a62275088b00b7241e6ff4136434c7","file_size":31259058,"content_type":"application/pdf","date_created":"2020-09-08T09:00:27Z","access_level":"open_access","relation":"main_file","creator":"dernst"}],"doi":"10.15479/AT:ISTA:8341","publication_identifier":{"issn":["2663-337X"]},"tmp":{"short":"CC BY-NC-SA (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","image":"/images/cc_by_nc_sa.png","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)"},"article_processing_charge":"No","department":[{"_id":"MaLo"}],"day":"08","oa":1,"title":"In vitro reconstitution of a Rab activation switch","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","citation":{"chicago":"Bezeljak, Urban. “In Vitro Reconstitution of a Rab Activation Switch.” Institute of Science and Technology Austria, 2020. <a href=\"https://doi.org/10.15479/AT:ISTA:8341\">https://doi.org/10.15479/AT:ISTA:8341</a>.","ieee":"U.

Each of these membrane-enclosed compartments has a distinct composition of lipids and proteins, which is essential for accurate membrane traffic and homeostasis. Interestingly, their biochemical identities are achieved with the help\r\nof small GTPases of the Rab family, which cycle between GDP- and GTP-bound forms on the selected membrane surface. While this activity switch is well understood for an individual protein, how Rab GTPases collectively transition between states to generate decisive signal propagation in space and time is unclear. In my PhD thesis, I present\r\nin vitro reconstitution experiments with theoretical modeling to systematically study a minimal Rab5 activation network from bottom-up. We find that positive feedback based on known molecular interactions gives rise to bistable GTPase activity switching on system’s scale. Furthermore, we determine that collective transition near the critical\r\npoint is intrinsically stochastic and provide evidence that the inactive Rab5 abundance on the membrane can shape the network response. Finally, we demonstrate that collective switching can spread on the lipid bilayer as a traveling activation wave, representing a possible emergent activity pattern in endosomal maturation. Together, our\r\nfindings reveal new insights into the self-organization properties of signaling networks away from chemical equilibrium. Our work highlights the importance of systematic characterization of biochemical systems in well-defined physiological conditions. This way, we were able to answer long-standing open questions in the field and close the gap between regulatory processes on a molecular scale and emergent responses on system’s level.","lang":"eng"}],"has_accepted_license":"1","status":"public","oa_version":"Published Version","date_created":"2020-09-08T08:53:53Z","type":"dissertation","corr_author":"1","date_updated":"2026-04-08T07:24:56Z","ddc":["570"],"OA_place":"publisher","page":"215","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"NanoFab"}],"author":[{"last_name":"Bezeljak","first_name":"Urban","orcid":"0000-0003-1365-5631","id":"2A58201A-F248-11E8-B48F-1D18A9856A87","full_name":"Bezeljak, Urban"}],"alternative_title":["ISTA Thesis"],"month":"09","related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"7580"}]},"publication_status":"published","file_date_updated":"2021-09-16T12:49:12Z","year":"2020"}]
