As such, a lot of attention has been devoted to the development of decoding algorithms with good error performance and efficient hardware implementation. One of the leading candidates in this regard is represented by successive-cancellation list (SCL) decoding. However, its hardware implementation requires a large amount of memory. Recently, a partitioned SCL (PSCL) decoder has been proposed to significantly reduce the memory consumption. In this paper, we consider the paradigm of PSCL decoding from a practical standpoint, and we provide several improvements. First, by changing the target signal-to-noise ratio and consequently modifying the construction of the code, we are able to improve the performance at no additional computational, latency, or memory cost. Second, we bridge the performance gap between SCL and PSCL decoding by introducing a generalized PSCL decoder and a layered PSCL decoder. In this way, we obtain almost the same performance of the SCL decoder with a significantly lower memory requirement, as testified by hardware implementation results. Third, we present an optimal scheme to allocate cyclic redundancy checks. Finally, we provide a lower bound on the list size that guarantees optimal maximum a posteriori performance for the binary erasure channel."}],"publication_status":"published","status":"public","language":[{"iso":"eng"}]},{"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","status":"public","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1801.03153","open_access":"1"}],"related_material":{"record":[{"status":"public","relation":"later_version","id":"7007"}]},"abstract":[{"text":"We present a coding paradigm that provides a new achievable rate for the primitive relay channel by combining compress-and-forward and decode-and-forward with a chaining construction. In the primitive relay channel model, the source broadcasts a message to the relay and to the destination; and the relay facilitates this communication by sending an additional message to the destination through a separate channel. Two well-known coding approaches for this setting are decode-and-forward and compress-and-forward: in the former, the relay decodes the message and sends some of the information to the destination; in the latter, the relay does not attempt to decode, but it sends a compressed description of the received sequence to the destination via Wyner-Ziv coding. In our scheme, we transmit over pairs of blocks and we use compress-and-forward for the first block and decode-and-forward for the second. In particular, in the first block, the relay does not attempt to decode and it sends only a part of the compressed description of the received sequence; in the second block, the relay decodes the message and sends this information plus the remaining part of the compressed sequence relative to the first block. As a result, we strictly outperform both compress-and- forward and decode-and-forward. Furthermore, this paradigm can be implemented with a low-complexity polar coding scheme that has the typical attractive features of polar codes, i.e., quasi-linear encoding/decoding complexity and super-polynomial decay of the error probability. Throughout the paper we consider as a running example the special case of the erasure relay channel and we compare the rates achievable by our proposed scheme with the existing upper and lower bounds.","lang":"eng"}],"publication_status":"published","extern":"1","type":"conference","citation":{"apa":"Mondelli, M., Hassani, H., &#38; Urbanke, R.

In particular, we take the point of view of modern coding theory and discuss how recent advances in coding for symmetric channels help provide more efficient solutions for the asymmetric case. We consider, in more detail, three basic coding paradigms. The first one is Gallager's scheme that consists of concatenating a linear code with a non-linear mapping so that the input distribution can be appropriately shaped. We explicitly show that both polar codes and spatially coupled codes can be employed in this scenario. Furthermore, we derive a scaling law between the gap to capacity, the cardinality of the input and output alphabets, and the required size of the mapper. The second one is an integrated scheme in which the code is used both for source coding, in order to create codewords distributed according to the capacity-achieving input distribution, and for channel coding, in order to provide error protection. Such a technique has been recently introduced by Honda and Yamamoto in the context of polar codes, and we show how to apply it also to the design of sparse graph codes. The third paradigm is based on an idea of Böcherer and Mathar, and separates the two tasks of source coding and channel coding by a chaining construction that binds together several codewords. We present conditions for the source code and the channel code, and we describe how to combine any source code with any channel code that fulfill those conditions, in order to provide capacity-achieving schemes for asymmetric channels. In particular, we show that polar codes, spatially coupled codes, and homophonic codes are suitable as basic building blocks of the proposed coding strategy. Rather than focusing on the exact details of the schemes, the purpose of this tutorial is to present different coding techniques that can then be implemented with many variants. There is no absolute winner and, in order to understand the most suitable technique for a specific application scenario, we provide a detailed comparison that takes into account several performance metrics.","lang":"eng"}],"language":[{"iso":"eng"}],"status":"public","_id":"6678","date_created":"2019-07-24T12:38:49Z","external_id":{"arxiv":["1406.7373"]},"publication":"IEEE Transactions on Information Theory","page":"3371-3393","date_published":"2018-05-01T00:00:00Z","date_updated":"2023-02-23T12:50:46Z","title":"How to achieve the capacity of asymmetric channels","month":"05","extern":"1","issue":"5","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"intvolume":"        64","volume":64,"main_file_link":[{"url":"https://arxiv.org/abs/1406.7373","open_access":"1"}],"related_material":{"record":[{"id":"6740","relation":"earlier_version","status":"public"}]}},{"page":"1633 - 1643","file_date_updated":"2020-07-14T12:47:37Z","publication":"Nature Ecology and Evolution","date_created":"2018-12-11T11:44:27Z","external_id":{"isi":["000447947600021"]},"project":[{"name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7","grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425"},{"_id":"2578D616-B435-11E9-9278-68D0E5697425","grant_number":"648440","call_identifier":"H2020","name":"Selective Barriers to Horizontal Gene Transfer"},{"_id":"251EE76E-B435-11E9-9278-68D0E5697425","grant_number":"24573","name":"Design principles underlying genetic switch architecture (DOC Fellowship)"}],"_id":"67","month":"09","date_updated":"2024-03-25T23:30:27Z","title":"Evolutionary potential of transcription factors for gene regulatory rewiring","ec_funded":1,"date_published":"2018-09-10T00:00:00Z","article_processing_charge":"No","scopus_import":"1","volume":2,"related_material":{"record":[{"status":"public","relation":"popular_science","id":"5585"},{"relation":"dissertation_contains","status":"public","id":"6371"}]},"issue":"10","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa":1,"intvolume":"         2","oa_version":"Submitted Version","doi":"10.1038/s41559-018-0651-y","day":"10","publisher":"Nature Publishing Group","department":[{"_id":"CaGu"},{"_id":"GaTk"},{"_id":"JoBo"}],"isi":1,"author":[{"full_name":"Igler, Claudia","last_name":"Igler","id":"46613666-F248-11E8-B48F-1D18A9856A87","first_name":"Claudia"},{"full_name":"Lagator, Mato","last_name":"Lagator","id":"345D25EC-F248-11E8-B48F-1D18A9856A87","first_name":"Mato"},{"orcid":"0000-0002-6699-1455","full_name":"Tkacik, Gasper","last_name":"Tkacik","first_name":"Gasper","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Jonathan P","id":"2C6FA9CC-F248-11E8-B48F-1D18A9856A87","last_name":"Bollback","orcid":"0000-0002-4624-4612","full_name":"Bollback, Jonathan P"},{"first_name":"Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","full_name":"Guet, Calin C","orcid":"0000-0001-6220-2052","last_name":"Guet"}],"year":"2018","citation":{"ama":"Igler C, Lagator M, Tkačik G, Bollback JP, Guet CC.

In vivo repression measurements of two repressors at mutated operator sites reveal their contrasting evolutionary potential: while robustness and evolvability were positively correlated, both were in trade-off with tunability. Epistatic interactions between adjacent operators alleviated this trade-off. A thermodynamic model explains how the differences in robustness, tunability and evolvability arise from biophysical characteristics of repressor–DNA binding. The model also uncovers that the energy matrix, which describes how mutations affect repressor–DNA binding, encodes crucial information about the evolutionary potential of a repressor. The biophysical determinants of evolutionary potential for regulatory rewiring constitute a mechanistic framework for understanding network evolution."}],"publication_status":"published","publist_id":"7987","quality_controlled":"1"},{"oa_version":"Preprint","arxiv":1,"publication":"2018 IEEE Global Communications Conference ","doi":"10.1109/glocom.2018.8647308","date_created":"2019-07-30T06:43:15Z","external_id":{"arxiv":["1806.11195"]},"day":"01","publisher":"IEEE","_id":"6728","month":"12","date_updated":"2021-01-12T08:08:42Z","title":"On the decoding of polar codes on permuted factor graphs","publication_identifier":{"isbn":["9781538647271"]},"author":[{"last_name":"Doan","full_name":"Doan, Nghia","first_name":"Nghia"},{"last_name":"Hashemi","full_name":"Hashemi, Seyyed Ali","first_name":"Seyyed Ali"},{"id":"27EB676C-8706-11E9-9510-7717E6697425","first_name":"Marco","last_name":"Mondelli","orcid":"0000-0002-3242-7020","full_name":"Mondelli, Marco"},{"last_name":"Gross","full_name":"Gross, Warren J.","first_name":"Warren J."}],"date_published":"2018-12-01T00:00:00Z","conference":{"name":"GLOBECOM: Global Communications Conference","start_date":"2018-12-09","location":"Abu Dhabi, United Arab Emirates","end_date":"2018-12-13"},"year":"2018","type":"conference","citation":{"apa":"Doan, N., Hashemi, S.

The belief propagation (BP) decoder allows for parallel decoding of polar codes, making it suitable for high throughput applications. However, the error-correction performance of polar codes under BP decoding is far from the requirements of 5G. It has been shown that the error-correction performance of BP can be improved if the decoding is performed on multiple permuted factor graphs of polar codes. However, a different BP decoding scheduling is required for each factor graph permutation which results in the design of a different decoder for each permutation. Moreover, the selection of the different factor graph permutations is at random, which prevents the decoder to achieve a desirable error correction performance with a small number of permutations. In this paper, we first show that the permutations on the factor graph can be mapped into suitable permutations on the codeword positions. As a result, we can make use of a single decoder for all the permutations. In addition, we introduce a method to construct a set of predetermined permutations which can provide the correct codeword if the decoding fails on the original permutation. We show that for the 5G polar code of length 1024, the error-correction performance of the proposed decoder is more than 0.25 dB better than that of the BP decoder with the same number of random permutations at the frame error rate of 10 -4 ."}],"publication_status":"published","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1806.11195"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"quality_controlled":"1"},{"_id":"6774","project":[{"grant_number":"M01980","_id":"25F8B9BC-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Robust invariants of Nonlinear Systems"},{"call_identifier":"FWF","_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1","name":"FWF Open Access Fund"}],"date_created":"2019-08-08T06:47:40Z","publication":"Journal of Applied and Computational Topology","file_date_updated":"2020-07-14T12:47:40Z","page":"177-231","date_published":"2018-12-01T00:00:00Z","title":"Computing simplicial representatives of homotopy group elements","date_updated":"2023-09-07T13:10:36Z","month":"12","intvolume":"         2","oa":1,"issue":"3-4","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"6681"}]},"volume":2,"publisher":"Springer","day":"01","doi":"10.1007/s41468-018-0021-5","oa_version":"Published Version","year":"2018","author":[{"last_name":"Filakovský","full_name":"Filakovský, Marek","first_name":"Marek","id":"3E8AF77E-F248-11E8-B48F-1D18A9856A87"},{"id":"473294AE-F248-11E8-B48F-1D18A9856A87","first_name":"Peter","last_name":"Franek","orcid":"0000-0001-8878-8397","full_name":"Franek, Peter"},{"full_name":"Wagner, Uli","orcid":"0000-0002-1494-0568","last_name":"Wagner","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","first_name":"Uli"},{"last_name":"Zhechev","full_name":"Zhechev, Stephan Y","id":"3AA52972-F248-11E8-B48F-1D18A9856A87","first_name":"Stephan Y"}],"department":[{"_id":"UlWa"}],"publication_identifier":{"issn":["2367-1726"],"eissn":["2367-1734"]},"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"},"ddc":["514"],"article_type":"original","file":[{"access_level":"open_access","file_name":"2018_JourAppliedComputTopology_Filakovsky.pdf","date_updated":"2020-07-14T12:47:40Z","content_type":"application/pdf","file_size":1056278,"checksum":"cf9e7fcd2a113dd4828774fc75cdb7e8","relation":"main_file","creator":"dernst","date_created":"2019-08-08T06:55:21Z","file_id":"6775"}],"type":"journal_article","citation":{"short":"M.

For the computational version of the problem, it is well known that there is no algorithm to decide whether the fundamental group  𝜋1(𝑋)  of a given finite simplicial complex X is trivial. On the other hand, there are several algorithms that, given a finite simplicial complex X that is simply connected (i.e., with   𝜋1(𝑋)  trivial), compute the higher homotopy group   𝜋𝑑(𝑋)  for any given   𝑑≥2 . However, these algorithms come with a caveat: They compute the isomorphism type of   𝜋𝑑(𝑋) ,   𝑑≥2  as an abstract finitely generated abelian group given by generators and relations, but they work with very implicit representations of the elements of   𝜋𝑑(𝑋) . Converting elements of this abstract group into explicit geometric maps from the d-dimensional sphere   𝑆𝑑  to X has been one of the main unsolved problems in the emerging field of computational homotopy theory. Here we present an algorithm that, given a simply connected space X, computes   𝜋𝑑(𝑋)  and represents its elements as simplicial maps from a suitable triangulation of the d-sphere   𝑆𝑑  to X. For fixed d, the algorithm runs in time exponential in   size(𝑋) , the number of simplices of X. Moreover, we prove that this is optimal: For every fixed   𝑑≥2 , we construct a family of simply connected spaces X such that for any simplicial map representing a generator of   𝜋𝑑(𝑋) , the size of the triangulation of   𝑆𝑑  on which the map is defined, is exponential in size(𝑋) ."}],"publication_status":"published","has_accepted_license":"1","status":"public","language":[{"iso":"eng"}]},{"date_created":"2018-12-11T11:44:27Z","_id":"68","project":[{"call_identifier":"FP7","_id":"2532554C-B435-11E9-9278-68D0E5697425","grant_number":"308036","name":"Lifelong Learning of Visual Scene Understanding"}],"page":"92","supervisor":[{"id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","first_name":"Christoph","last_name":"Lampert","orcid":"0000-0001-8622-7887","full_name":"Lampert, Christoph"}],"pubrep_id":"1048","file_date_updated":"2020-07-14T12:47:40Z","ec_funded":1,"article_processing_charge":"No","date_published":"2018-09-01T00:00:00Z","month":"09","title":"Learning from dependent data","date_updated":"2023-09-07T12:29:07Z","oa":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","alternative_title":["ISTA Thesis"],"day":"01","publisher":"Institute of Science and Technology Austria","oa_version":"Published Version","doi":"10.15479/AT:ISTA:TH1048","year":"2018","author":[{"last_name":"Zimin","full_name":"Zimin, Alexander","first_name":"Alexander","id":"37099E9C-F248-11E8-B48F-1D18A9856A87"}],"department":[{"_id":"ChLa"}],"publication_identifier":{"issn":["2663-337X"]},"degree_awarded":"PhD","ddc":["004","519"],"type":"dissertation","citation":{"ista":"Zimin A. 2018.

This disparity between the machine learning theory and applications underlies a growing demand in the development of algorithms that learn from dependent data and theory that can provide generalization guarantees similar to the independent situations. This thesis is dedicated to two variants of dependencies that can arise in practice. One is a dependence on the level of samples in a single learning task. Another dependency type arises in the multi-task setting when the tasks are dependent on each other even though the data for them can be i.i.d. In both cases we model the data (samples or tasks) as stochastic processes and introduce new algorithms for both settings that take into account and exploit the resulting dependencies. We prove the theoretical guarantees on the performance of the introduced algorithms under different evaluation criteria and, in addition, we compliment the theoretical study by the empirical one, where we evaluate some of the algorithms on two real world datasets to highlight their practical applicability.","lang":"eng"}],"publication_status":"published"},{"oa":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"23"},{"status":"public","relation":"part_of_dissertation","id":"840"}]},"alternative_title":["ISTA Thesis"],"article_processing_charge":"No","date_published":"2018-09-01T00:00:00Z","date_updated":"2023-09-26T15:50:22Z","title":"Charge sensing and spin relaxation times of holes in Ge hut wires","month":"09","_id":"69","date_created":"2018-12-11T11:44:28Z","supervisor":[{"id":"38DB5788-F248-11E8-B48F-1D18A9856A87","first_name":"Georgios","full_name":"Katsaros, Georgios","orcid":"0000-0001-8342-202X","last_name":"Katsaros"}],"pubrep_id":"1047","file_date_updated":"2020-07-14T12:47:44Z","page":"103","publist_id":"7985","abstract":[{"text":"A qubit, a unit of quantum information, is essentially any quantum mechanical two-level system which can be coherently controlled.

This leads to loss of the information stored in the qubit. The upper bound of the time scale on which decoherence happens is set by the spin relaxation time. In this thesis I studied a two-level system consisting of a Zeeman-split hole spin confined in a quantum dot formed in a Ge hut wire. Such Ge hut wires have emerged as a promising material system for the realization of spin qubits, due to the combination of two significant properties: long spin coherence time as expected for group IV semiconductors due to the low hyperfine interaction and a strong valence band spin-orbit coupling. Here, I present how to fabricate quantum dot devices suitable for electrical transport measurements. Coupled quantum dot devices allowed the realization of a charge sensor, which is electrostatically and tunnel coupled to a quantum dot. By integrating the charge sensor into a radio-frequency reflectometry setup, I performed for the first time single-shot readout measurements of hole spins and extracted the hole spin relaxation times in Ge hut wires.","lang":"eng"}],"publication_status":"published","has_accepted_license":"1","status":"public","language":[{"iso":"eng"}],"ddc":["530","600"],"file":[{"creator":"dernst","date_created":"2019-04-09T07:00:40Z","file_id":"6247","access_level":"open_access","file_name":"2018_Thesis_Vukusic.pdf","date_updated":"2020-07-14T12:47:44Z","content_type":"application/pdf","file_size":28452385,"checksum":"c570b656e30749cd65b1c7e13a9ce0a8","relation":"main_file"},{"access_level":"closed","file_name":"2018_Thesis_Vukusic_source.zip","content_type":"application/zip","date_updated":"2020-07-14T12:47:44Z","file_size":53058704,"checksum":"7856771d9cd401fe0b311191076db6e1","relation":"source_file","creator":"dernst","date_created":"2019-04-09T07:00:40Z","file_id":"6248"}],"type":"dissertation","citation":{"mla":"Vukušić, Lada. <i>Charge Sensing and Spin Relaxation Times of Holes in Ge Hut Wires</i>.

Imprinted genes are essential for brain development, and deregulation of imprinting is associated with neurodevelopmental diseases and the pathogenesis of psychiatric disorders. However, the cell-type specificity of imprinting at single cell resolution, and how imprinting and thus gene dosage regulates neuronal circuit assembly is still largely unknown. Here, MADM (Mosaic Analysis with Double Markers) technology was employed to assess genomic imprinting at single cell level. By visualizing MADM-induced uniparental disomies (UPDs) in distinct colors at single cell level in genetic mosaic animals, this experimental paradigm provides a unique quantitative platform to systematically assay the UPD-mediated imbalances in imprinted gene expression at unprecedented resolution. An experimental pipeline based on FACS, RNA-seq and bioinformatics analysis was established and applied to systematically map cell-type-specific ‘imprintomes’ in the mouse brain. The results revealed that parental-specific expression of imprinted genes per se is rarely cell-type-specific even at the individual cell level. Conversely, when we extended the comparison to downstream responses resulting from imbalanced imprinted gene expression, we discovered an unexpectedly high degree of cell-type specificity. Furthermore, we determined a novel function of genomic imprinting in cortical astrocyte production and in olfactory bulb (OB) granule cell generation. These results suggest important functional implication of genomic imprinting for generating cell-type diversity in the brain. In addition, MADM provides a powerful tool to study candidate genes by concomitant genetic manipulation and fluorescent labelling of single cells. MADM-based candidate gene approach was utilized to identify potential imprinted genes involved in the generation of cortical astrocytes and OB granule cells. We investigated p57Kip2, a maternally expressed gene and known cell cycle regulator. Although we found that p57Kip2 does not play a role in these processes, we detected an unexpected function of the paternal allele previously thought to be silent. Finally, we took advantage of a key property of MADM which is to allow unambiguous investigation of environmental impact on single cells. The experimental pipeline based on FACS and RNA-seq analysis of MADM-labeled cells was established to probe the functional differences of single cell loss of gene function compared to global loss of function on a transcriptional level. With this method, both common and distinct responses were isolated due to cell-autonomous and non-autonomous effects acting on genotypically identical cells. As a result, transcriptional changes were identified which result solely from the surrounding environment. Using the MADM technology to study genomic imprinting at single cell resolution, we have identified cell-type-specific gene expression, novel gene function and the impact of environment on single cell transcriptomes. Together, these provide important insights to the understanding of mechanisms regulating cell-type specificity and thus diversity in the brain."}],"publication_status":"published","publist_id":"8046","type":"dissertation","citation":{"chicago":"Laukoter, Susanne. “Role of Genomic Imprinting in Cerebral Cortex Development.” Institute of Science and Technology Austria, 2018. <a href=\"https://doi.org/10.15479/AT:ISTA:th1057\">https://doi.org/10.15479/AT:ISTA:th1057</a>.","ama":"Laukoter S.

We show that counting the periods of the jittery clock signal produces random numbers of significantly better quality than the methods in which the jittery signal is simply sampled (the case in almost all current methods). Moreover, we use the counter values to characterize and continuously monitor the source of randomness. However, instead of using the widely used statistical variance, we propose to use Allan variance to do so. There are two main advantages: Allan variance is insensitive to low frequency noises such as flicker noise that are known to be autocorrelated and significantly less circuitry is required for its computation than that used to compute commonly used variance. We also show that it is essential to use a differential principle of randomness extraction from the jitter based on the use of two identical oscillators to avoid autocorrelations originating from external and internal global jitter sources and that this fact is valid for both kinds of rings. Last but not least, we propose a method of statistical testing based on high order Markov model to show the reduced dependencies when the proposed randomness extraction is applied."}],"quality_controlled":"1","oa_version":"Published Version","doi":"10.13154/tches.v2018.i3.214-242","day":"01","publisher":"International Association for Cryptologic Research","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"},"publication_identifier":{"eissn":["2569-2925"]},"department":[{"_id":"KrPi"}],"year":"2018","author":[{"first_name":"Elie Noumon","full_name":"Allini, Elie Noumon","last_name":"Allini"},{"last_name":"Skórski","full_name":"Skórski, Maciej","first_name":"Maciej","id":"EC09FA6A-02D0-11E9-8223-86B7C91467DD"},{"last_name":"Petura","full_name":"Petura, Oto","first_name":"Oto"},{"last_name":"Bernard","full_name":"Bernard, Florent","first_name":"Florent"},{"first_name":"Marek","last_name":"Laban","full_name":"Laban, Marek"},{"first_name":"Viktor","full_name":"Fischer, Viktor","last_name":"Fischer"}],"scopus_import":"1","volume":2018,"oa":1,"intvolume":"      2018","issue":"3","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","page":"214-242","publication":"IACR Transactions on Cryptographic Hardware and Embedded Systems","file_date_updated":"2021-11-15T10:27:29Z","date_created":"2021-11-14T23:01:25Z","_id":"10286","month":"01","title":"Evaluation and monitoring of free running oscillators serving as source of randomness","date_updated":"2021-11-15T10:48:49Z","article_processing_charge":"No","date_published":"2018-01-01T00:00:00Z"},{"quality_controlled":"1","pmid":1,"status":"public","language":[{"iso":"eng"}],"publication_status":"published","abstract":[{"lang":"eng","text":"The misfolding and aggregation of proteins into linear fibrils is widespread in human biology, for example, in connection with amyloid formation and the pathology of neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases. The oligomeric species that are formed in the early stages of protein aggregation are of great interest, having been linked with the cellular toxicity associated with these conditions. However, these species are not characterized in any detail experimentally, and their properties are not well understood. Many of these species have been found to have approximately spherical morphology and to be held together by hydrophobic interactions. We present here an analytical statistical mechanical model of globular oligomer formation from simple idealized amphiphilic protein monomers and show that this correlates well with Monte Carlo simulations of oligomer formation. We identify the controlling parameters of the model, which are closely related to simple quantities that may be fitted directly from experiment. We predict that globular oligomers are unlikely to form at equilibrium in many polypeptide systems but instead form transiently in the early stages of amyloid formation. We contrast the globular model of oligomer formation to a well-established model of linear oligomer formation, highlighting how the differing ensemble properties of linear and globular oligomers offer a potential strategy for characterizing oligomers from experimental measurements."}],"article_type":"original","type":"journal_article","citation":{"short":"A.J.

This is because these processes involve multiple molecular mechanisms that are associated with the rearrangement of large numbers of weak bonds, resulting in complex free energy landscapes with many kinetic barriers. Reaction rate measurements at different temperatures can offer unprecedented insights into the underlying molecular mechanisms. However, to be able to interpret such measurements, a key challenge is to establish which properties of the complex free energy landscapes are probed by the reaction rate. Here, we present a reaction rate theory for supramolecular kinetics based on Kramers theory of diffusive reactions over multiple kinetic barriers. We find that reaction rates for protein aggregation are of the Arrhenius–Eyring type and that the associated activation energies probe only one relevant barrier along the respective free energy landscapes. We apply this advancement to interpret, in experiments and in coarse-grained computer simulations, reaction rates of amyloid aggregation in terms of molecular mechanisms and associated thermodynamic signatures. These results suggest a practical extension of the concept of rate-determining steps for complex supramolecular processes and establish a general platform for probing the underlying energy landscape using kinetic measurements.","lang":"eng"}],"language":[{"iso":"eng"}],"status":"public","quality_controlled":"1","type":"journal_article","citation":{"chicago":"Michaels, Thomas C.

Most of these components do not bind the cargo. Here, we show that such “inert” components can be crucial for the precise control of cross-membrane trafficking. Using a statistical mechanics model and molecular dynamics simulations, we demonstrate that the presence of inert membrane components of small isotropic curvatures dramatically influences cargo endocytosis, even if the total spontaneous curvature of such a membrane remains unchanged. Curved lipids, such as cholesterol, as well as asymmetrically included proteins and tethered sugars can, therefore, actively participate in the control of the membrane trafficking of nanoscopic cargo. We find that even a low-level expression of curved inert membrane components can determine the membrane selectivity toward the cargo size and can be used to selectively target membranes of certain compositions. Our results suggest a robust and general method of controlling cargo trafficking by adjusting the membrane composition without needing to alter the concentration of receptors or the average membrane curvature. This study indicates that cells can prepare for any trafficking event by incorporating curved inert components in either of the membrane leaflets.","lang":"eng"}],"publication_status":"published","quality_controlled":"1","page":"5350-5356","publication":"Nano Letters","external_id":{"pmid":["29667410"]},"date_created":"2021-11-26T12:15:47Z","_id":"10359","month":"04","title":"Controlling cargo trafficking in multicomponent membranes","date_updated":"2021-11-26T15:14:08Z","keyword":["mechanical engineering","condensed matter physics"],"article_processing_charge":"No","date_published":"2018-04-18T00:00:00Z","extern":"1","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1712.10147"}],"volume":18,"oa":1,"intvolume":"        18","issue":"9","acknowledgement":"We acknowledge discussions with Giuseppe Battaglia as well as support from the Herchel Smith scholarship (T.C.), the CAS PIFI fellowship (T.C.), the UCL Institute for the Physics of Living Systems (T.C. and A.Š.), the Austrian Academy of Sciences through a DOC fellowship (P.W.), the European Union Horizon 2020 programme under ETN grant no. 674979-NANOTRANS and FET grant no. 766972-NANOPHLOW (J.D. and D.F.), the Engineering and Physical Sciences Research Council (D.F. and A.Š.), the Academy of Medical Sciences and Wellcome Trust (A.Š.), and the Royal Society (A.Š.).

Our results reveal that interactions between monomeric Aβ42 and amyloid fibrils during fibril-dependent secondary nucleation fundamentally reverse the thermodynamic signature of this process relative to primary nucleation, even though both processes generate aggregates from soluble peptides. By mapping the energetic and entropic contributions along the reaction trajectories, we show that the catalytic efficiency of Aβ42 fibril surfaces results from the enthalpic stabilization of adsorbing peptides in conformations amenable to nucleation, resulting in a dramatic lowering of the activation energy for nucleation."}],"publication_status":"published","quality_controlled":"1","citation":{"chicago":"Cohen, Samuel I.

They impose a diffusion barrier to macromolecules and enable the selective transport of nuclear transport receptors with bound cargo. The underlying mechanisms that establish these permeability properties remain to be fully elucidated but require unstructured nuclear pore proteins rich in Phe-Gly (FG)-repeat domains of different types, such as FxFG and GLFG. While physical modeling and in vitro approaches have provided a framework for explaining how the FG network contributes to the barrier and transport properties of the NPC, it remains unknown whether the number and/or the spatial positioning of different FG-domains along a cylindrical, ∼40 nm diameter transport channel contributes to their collective properties and function. To begin to answer these questions, we have used DNA origami to build a cylinder that mimics the dimensions of the central transport channel and can house a specified number of FG-domains at specific positions with easily tunable design parameters, such as grafting density and topology. We find the overall morphology of the FG-domain assemblies to be dependent on their chemical composition, determined by the type and density of FG-repeat, and on their architectural confinement provided by the DNA cylinder, largely consistent with here presented molecular dynamics simulations based on a coarse-grained polymer model. In addition, high-speed atomic force microscopy reveals local and reversible FG-domain condensation that transiently occludes the lumen of the DNA central channel mimics, suggestive of how the NPC might establish its permeability properties.","lang":"eng"}],"publication_status":"published","pmid":1,"status":"public","language":[{"iso":"eng"}],"article_type":"original","type":"journal_article","citation":{"mla":"Fisher, Patrick D.

To successfully colonize its host, U. maydis secretes proteins, known as effectors, that suppress plant defense responses and facilitate the establishment of biotrophy. In this work, we describe the U. maydis effector protein Cce1. Cce1 is essential for virulence and is upregulated during infection. Through microscopic analysis and in vitro assays, we show that Cce1 is secreted from hyphae during filamentous growth of the fungus. Strikingly, Δcce1 mutants are blocked at early stages of infection and induce callose deposition as a plant defense response. Cce1 is highly conserved among smut fungi and the Ustilago bromivora ortholog complemented the virulence defect of the SG200Δcce1 deletion strain. These data indicate that Cce1 is a core effector with apoplastic localization that is essential for U. maydis to infect its host."}],"publication_status":"published","publist_id":"7950","quality_controlled":"1","type":"journal_article","citation":{"ama":"Seitner D, Uhse S, Gallei MC, Djamei A.
