By doing so, they hope to reduce the number of coupons that must be sampled by each collector in order to obtain a full set. This extension is natural when considering real-world manifestations of the coupon collector phenomenon, and has been remarked upon and studied empirically (Hayes and Hannigan 2006, Ahmad et al. 2014, Delmarcelle 2019).\r\n\r\nWe provide the first theoretical analysis for such a scenario. We find that “coupon collecting with friends” can indeed significantly reduce the number of coupons each collector must sample, and raises interesting connections to the more traditional variants of the problem. While our analysis is in most cases asymptotically tight, there are several open questions raised, regarding finer-grained analysis of both “coupon collecting with friends,” and of a long-studied variant of the original problem in which a collector requires multiple full sets of coupons.","lang":"eng"}]},{"file_date_updated":"2022-07-02T22:30:06Z","acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"NanoFab"},{"_id":"M-Shop"}],"tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"date_updated":"2023-09-07T13:33:27Z","alternative_title":["ISTA Thesis"],"doi":"10.15479/at:ista:9623","related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"9750"},{"relation":"part_of_dissertation","status":"public","id":"9006"}]},"article_processing_charge":"No","date_published":"2021-07-01T00:00:00Z","author":[{"full_name":"Caballero Mancebo, Silvia","id":"2F1E1758-F248-11E8-B48F-1D18A9856A87","first_name":"Silvia","orcid":"0000-0002-5223-3346","last_name":"Caballero Mancebo"}],"degree_awarded":"PhD","publication_status":"published","file":[{"date_created":"2021-07-01T14:48:54Z","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","embargo_to":"open_access","creator":"scaballe","access_level":"closed","relation":"source_file","file_name":"PhDThesis_SCM.docx","checksum":"e039225a47ef32666d59bf35ddd30ecf","file_size":131946790,"date_updated":"2022-07-02T22:30:06Z","file_id":"9624"},{"file_size":17094958,"file_name":"PhDThesis_SCM.pdf","checksum":"dd4d78962ea94ad95e97ca7d9af08f4b","file_id":"9625","embargo":"2022-07-01","date_updated":"2022-07-02T22:30:06Z","content_type":"application/pdf","date_created":"2021-07-01T14:46:25Z","relation":"main_file","access_level":"open_access","creator":"scaballe"}],"ddc":["570"],"language":[{"iso":"eng"}],"month":"07","publisher":"Institute of Science and Technology Austria","department":[{"_id":"GradSch"},{"_id":"CaHe"}],"title":"Fertilization-induced deformations are controlled by the actin cortex and a mitochondria-rich subcortical layer in ascidian oocytes","oa_version":"Published Version","date_created":"2021-07-01T14:50:17Z","abstract":[{"text":"Cytoplasmic reorganizations are essential for morphogenesis. In large cells like oocytes, these reorganizations become crucial in patterning the oocyte for later stages of embryonic development. Ascidians oocytes reorganize their cytoplasm (ooplasm) in a spectacular manner. Ooplasmic reorganization is initiated at fertilization with the contraction of the actomyosin cortex along the animal-vegetal axis of the oocyte, driving the accumulation of cortical endoplasmic reticulum (cER), maternal mRNAs associated to it and a mitochondria-rich subcortical layer – the myoplasm – in a region of the vegetal pole termed contraction pole (CP). Here we have used the species Phallusia mammillata to investigate the changes in cell shape that accompany these reorganizations and the mechanochemical mechanisms underlining CP formation.\r\nWe report that the length of the animal-vegetal (AV) axis oscillates upon fertilization: it first undergoes a cycle of fast elongation-lengthening followed by a slow expansion of mainly the vegetal pole (VP) of the cell. We show that the fast oscillation corresponds to a dynamic polarization of the actin cortex as a result of a fertilization-induced increase in cortical tension in the oocyte that triggers a rupture of the cortex at the animal pole and the establishment of vegetal-directed cortical flows. These flows are responsible for the vegetal accumulation of actin causing the VP to flatten. \r\nWe find that the slow expansion of the VP, leading to CP formation, correlates with a relaxation of the vegetal cortex and that the myoplasm plays a role in the expansion. We show that the myoplasm is a solid-like layer that buckles under compression forces arising from the contracting actin cortex at the VP. Straightening of the myoplasm when actin flows stops, facilitates the expansion of the VP and the CP. Altogether, our results present a previously unrecognized role for the myoplasm in ascidian ooplasmic segregation. \r\n","lang":"eng"}],"type":"dissertation","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","page":"111","has_accepted_license":"1","year":"2021","_id":"9623","supervisor":[{"id":"39427864-F248-11E8-B48F-1D18A9856A87","full_name":"Heisenberg, Carl-Philipp J","orcid":"0000-0002-0912-4566","last_name":"Heisenberg","first_name":"Carl-Philipp J"}],"status":"public","oa":1,"publication_identifier":{"issn":["2663-337X"],"isbn":["978-3-99078-012-1"]},"citation":{"mla":"Caballero Mancebo, Silvia. <i>Fertilization-Induced Deformations Are Controlled by the Actin Cortex and a Mitochondria-Rich Subcortical Layer in Ascidian Oocytes</i>.

Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap engineering and vacancy compensation. We found that PbTe can significantly reduce the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain boundary could also reduce the intergrain energy barrier which largely enhances the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe.

However, the nature and coordination of the underlying forces remains poorly characterized. Here, using light-sheet microscopy and large-scale imaging quantification, we demonstrate that crypt formation coincides with a stark reduction in lumen volume. We develop a 3D biophysical model to computationally screen different mechanical scenarios of crypt morphogenesis. Combining this with live-imaging data and multiple mechanical perturbations, we show that actomyosin-driven crypt apical contraction and villus basal tension work synergistically with lumen volume reduction to drive crypt morphogenesis, and demonstrate the existence of a critical point in differential tensions above which crypt morphology becomes robust to volume changes. Finally, we identified a sodium/glucose cotransporter that is specific to differentiated enterocytes that modulates lumen volume reduction through cell swelling in the villus region. Together, our study uncovers the cellular basis of how cell fate modulates osmotic and actomyosin forces to coordinate robust morphogenesis.","lang":"eng"}],"ec_funded":1,"date_created":"2021-07-04T22:01:25Z","oa_version":"Preprint","publication":"Nature Cell Biology","title":"Cell fate coordinates mechano-osmotic forces in intestinal crypt formation","department":[{"_id":"EdHa"}],"publisher":"Springer Nature","isi":1,"month":"06","language":[{"iso":"eng"}],"project":[{"name":"Design Principles of Branching Morphogenesis","grant_number":"851288","_id":"05943252-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020"},{"grant_number":"P31639","name":"Active mechano-chemical description of the cell cytoskeleton","_id":"268294B6-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"pmid":1,"day":"21","intvolume":"        23","main_file_link":[{"url":"https://www.biorxiv.org/content/10.1101/2020.05.13.094359","open_access":"1"}],"publication_status":"published","scopus_import":"1","quality_controlled":"1","date_published":"2021-06-21T00:00:00Z","author":[{"full_name":"Yang, Qiutan","last_name":"Yang","first_name":"Qiutan"},{"first_name":"Shi-lei","last_name":"Xue","full_name":"Xue, Shi-lei","id":"31D2C804-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Chan","first_name":"Chii Jou","full_name":"Chan, Chii Jou"},{"first_name":"Markus","last_name":"Rempfler","full_name":"Rempfler, Markus"},{"first_name":"Dario","last_name":"Vischi","full_name":"Vischi, Dario"},{"last_name":"Maurer-Gutierrez","first_name":"Francisca","full_name":"Maurer-Gutierrez, Francisca"},{"full_name":"Hiiragi, Takashi","first_name":"Takashi","last_name":"Hiiragi"},{"id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","full_name":"Hannezo, Edouard B","orcid":"0000-0001-6005-1561","last_name":"Hannezo","first_name":"Edouard B"},{"full_name":"Liberali, Prisca","first_name":"Prisca","last_name":"Liberali"}],"article_processing_charge":"No","date_updated":"2023-08-10T13:57:36Z","doi":"10.1038/s41556-021-00700-2"},{"status":"public","oa":1,"citation":{"chicago":"Higginbotham, Andrew P. “Data for ‘Breakdown of Induced p ± Ip Pairing in a Superconductor-Semiconductor Hybrid.’” Institute of Science and Technology Austria, 2021.","ieee":"A.

Population structure is known to affect the dynamics of the evolutionary process. Amplifiers of selection are population structures that increase the fixation probability of beneficial mutants compared to well-mixed populations. Over the past 15 years, extensive research has produced remarkable structures called strong amplifiers which guarantee that every beneficial mutation fixates with high probability. But strong amplification has come at the cost of considerably delaying the fixation event, which can slow down the overall rate of evolution. However, the precise relationship between fixation probability and time has remained elusive. Here we characterize the slowdown effect of strong amplification. First, we prove that all strong amplifiers must delay the fixation event at least to some extent. Second, we construct strong amplifiers that delay the fixation event only marginally as compared to the well-mixed populations. Our results thus establish a tight relationship between fixation probability and time: Strong amplification always comes at a cost of a slowdown, but more than a marginal slowdown is not needed.","lang":"eng"}],"intvolume":"        12","file":[{"file_size":628992,"checksum":"5767418926a7f7fb76151de29473dae0","file_name":"2021_NatCoom_Tkadlec.pdf","file_id":"9692","date_updated":"2021-07-19T13:02:20Z","content_type":"application/pdf","date_created":"2021-07-19T13:02:20Z","success":1,"relation":"main_file","creator":"cziletti","access_level":"open_access"}],"publication_status":"published","month":"06","isi":1,"project":[{"call_identifier":"FP7","name":"Quantitative Graph Games: Theory and Applications","grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"},{"name":"Modern Graph Algorithmic Techniques in Formal Verification","grant_number":"P 23499-N23","_id":"2584A770-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23","name":"Rigorous Systems Engineering"}],"language":[{"iso":"eng"}],"pmid":1,"ddc":["510"],"day":"29","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"},"file_date_updated":"2021-07-19T13:02:20Z","article_number":"4009","scopus_import":"1","quality_controlled":"1","author":[{"id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87","full_name":"Tkadlec, Josef","last_name":"Tkadlec","orcid":"0000-0002-1097-9684","first_name":"Josef"},{"orcid":"0000-0002-8943-0722","last_name":"Pavlogiannis","first_name":"Andreas","id":"49704004-F248-11E8-B48F-1D18A9856A87","full_name":"Pavlogiannis, Andreas"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu"},{"last_name":"Nowak","first_name":"Martin A.","full_name":"Nowak, Martin A."}],"date_published":"2021-06-29T00:00:00Z","article_processing_charge":"No","doi":"10.1038/s41467-021-24271-w","date_updated":"2025-07-14T09:10:05Z"},{"abstract":[{"lang":"eng","text":"At the encounter with a novel environment, contextual memory formation is greatly enhanced, accompanied with increased arousal and active exploration. Although this phenomenon has been widely observed in animal and human daily life, how the novelty in the environment is detected and contributes to contextual memory formation has lately started to be unveiled. The hippocampus has been studied for many decades for its largely known roles in encoding spatial memory, and a growing body of evidence indicates a differential involvement of dorsal and ventral hippocampal divisions in novelty detection. In this brief review article, we discuss the recent findings of the role of mossy cells in the ventral hippocampal moiety in novelty detection and put them in perspective with other novelty-related pathways in the hippocampus. We propose a mechanism for novelty-driven memory acquisition in the dentate gyrus by the direct projection of ventral mossy cells to dorsal dentate granule cells. By this projection, the ventral hippocampus sends novelty signals to the dorsal hippocampus, opening a gate for memory encoding in dentate granule cells based on information coming from the entorhinal cortex. We conclude that, contrary to the presently accepted functional independence, the dorsal and ventral hippocampi cooperate to link the novelty and contextual information, and this dorso-ventral interaction is crucial for the novelty-dependent memory formation."}],"publication":"Neurobiology of Learning and Memory","title":"The role of hippocampal mossy cells in novelty detection","department":[{"_id":"RySh"}],"publisher":"Elsevier","ec_funded":1,"date_created":"2021-07-11T22:01:16Z","oa_version":"Published Version","acknowledgement":"This work was supported by a European Research Council Advanced Grant 694539 to Ryuichi Shigemoto.","status":"public","oa":1,"external_id":{"isi":["000677694900004"],"pmid":["34214666"]},"article_type":"original","citation":{"chicago":"Fredes, Felipe, and Ryuichi Shigemoto. “The Role of Hippocampal Mossy Cells in Novelty Detection.” <i>Neurobiology of Learning and Memory</i>.

Current strategies to remove PNN are long-lasting, invasive, and trigger neuropsychiatric symptoms. Here, we apply repeated anesthetic ketamine as a method with minimal behavioral effect. We find that this paradigm strongly reduces PNN coating in the healthy adult brain and promotes juvenile-like plasticity. Microglia are critically involved in PNN loss because they engage with parvalbumin-positive neurons in their defined cortical layer. We identify external 60-Hz light-flickering entrainment to recapitulate microglia-mediated PNN removal. Importantly, 40-Hz frequency, which is known to remove amyloid plaques, does not induce PNN loss, suggesting microglia might functionally tune to distinct brain frequencies. Thus, our 60-Hz light-entrainment strategy provides an alternative form of PNN intervention in the healthy adult brain."}]},{"day":"01","language":[{"iso":"eng"}],"project":[{"grant_number":"863818","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020"}],"isi":1,"month":"06","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2104.01189"}],"publication_status":"published","author":[{"first_name":"Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ehsan Kafshdar","last_name":"Goharshady","full_name":"Goharshady, Ehsan Kafshdar"},{"last_name":"Novotný","first_name":"Petr","id":"3CC3B868-F248-11E8-B48F-1D18A9856A87","full_name":"Novotný, Petr"},{"full_name":"Zikelic, Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","first_name":"Dorde","orcid":"0000-0002-4681-1699","last_name":"Zikelic"}],"date_published":"2021-06-01T00:00:00Z","doi":"10.1145/3453483.3454093","date_updated":"2025-07-14T09:10:06Z","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"14539"}]},"article_processing_charge":"No","scopus_import":"1","quality_controlled":"1","conference":{"start_date":"2021-06-20","location":"Online","end_date":"2021-06-26","name":"PLDI: Programming Language Design and Implementation"},"acknowledgement":"We thank the anonymous reviewers for their helpful comments.

Our technique is rather simple but efficient. It relies on a purely syntactic reversal of the program's transition system followed by a constraint-based invariant synthesis with constraints coming from both the original and the reversed transition system. The latter task is performed by a simple call to an off-the-shelf SMT-solver, which allows us to leverage the latest advances in SMT-solving. Moreover, our method offers a combination of features not present (as a whole) in previous approaches: it handles programs with non-determinism, provides relative completeness guarantees and supports programs with polynomial arithmetic. The experiments performed with our prototype tool RevTerm show that our approach, despite its simplicity and stronger theoretical guarantees, is at least on par with the state-of-the-art tools, often achieving a non-trivial improvement under a proper configuration of its parameters."}],"title":"Proving non-termination by program reversal","department":[{"_id":"KrCh"}],"publication":"Proceedings of the 42nd ACM SIGPLAN International Conference on Programming Language Design and Implementation","publisher":"Association for Computing Machinery","oa_version":"Preprint","date_created":"2021-07-11T22:01:17Z","ec_funded":1},{"article_processing_charge":"No","date_updated":"2025-07-14T09:10:06Z","doi":"10.1145/3453483.3454076","date_published":"2021-06-01T00:00:00Z","author":[{"last_name":"Asadi","first_name":"Ali","full_name":"Asadi, Ali"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu"},{"last_name":"Fu","first_name":"Hongfei","id":"3AAD03D6-F248-11E8-B48F-1D18A9856A87","full_name":"Fu, Hongfei"},{"last_name":"Goharshady","orcid":"0000-0003-1702-6584","first_name":"Amir Kafshdar","id":"391365CE-F248-11E8-B48F-1D18A9856A87","full_name":"Goharshady, Amir Kafshdar"},{"first_name":"Mohammad","last_name":"Mahdavi","full_name":"Mahdavi, Mohammad"}],"quality_controlled":"1","scopus_import":"1","conference":{"name":" PLDI: Programming Language Design and Implementation","end_date":"2021-06-26","location":"Online","start_date":"2021-06-20"},"day":"01","month":"06","isi":1,"project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020"},{"_id":"267066CE-B435-11E9-9278-68D0E5697425","name":"Quantitative Analysis of Probablistic Systems with a focus on Crypto-currencies"}],"language":[{"iso":"eng"}],"publication_status":"published","main_file_link":[{"url":"https://hal.archives-ouvertes.fr/hal-03183862/","open_access":"1"}],"abstract":[{"lang":"eng","text":"We consider the fundamental problem of reachability analysis over imperative programs with real variables. Previous works that tackle reachability are either unable to handle programs consisting of general loops (e.g. symbolic execution), or lack completeness guarantees (e.g. abstract interpretation), or are not automated (e.g. incorrectness logic). In contrast, we propose a novel approach for reachability analysis that can handle general and complex loops, is complete, and can be entirely automated for a wide family of programs. Through the notion of Inductive Reachability Witnesses (IRWs), our approach extends ideas from both invariant generation and termination to reachability analysis.\r\n\r\nWe first show that our IRW-based approach is sound and complete for reachability analysis of imperative programs. Then, we focus on linear and polynomial programs and develop automated methods for synthesizing linear and polynomial IRWs. In the linear case, we follow the well-known approaches using Farkas' Lemma. Our main contribution is in the polynomial case, where we present a push-button semi-complete algorithm. We achieve this using a novel combination of classical theorems in real algebraic geometry, such as Putinar's Positivstellensatz and Hilbert's Strong Nullstellensatz. Finally, our experimental results show we can prove complex reachability objectives over various benchmarks that were beyond the reach of previous methods."}],"publisher":"Association for Computing Machinery","publication":"Proceedings of the 42nd ACM SIGPLAN International Conference on Programming Language Design and Implementation","department":[{"_id":"KrCh"}],"title":"Polynomial reachability witnesses via Stellensätze","date_created":"2021-07-11T22:01:17Z","ec_funded":1,"oa_version":"Submitted Version","external_id":{"isi":["000723661700050"]},"status":"public","oa":1,"acknowledgement":"This research was partially supported by the ERC CoG 863818 (ForM-SMArt), the National Natural Science Foundation of China (NSFC) Grant No. 61802254, the Huawei Innovation Research Program, the Facebook PhD Fellowship Program, and DOC Fellowship No. 24956 of the Austrian Academy of Sciences (ÖAW).","publication_identifier":{"isbn":["9781450383912"]},"citation":{"apa":"Asadi, A., Chatterjee, K., Fu, H., Goharshady, A.

The ensuing regulating function is often represented as a combinational logic circuit, where output (gene expression) is determined by current input values (promoter bound TFs) only. However, the simultaneous arrival of TFs is a strong assumption, since transcription and translation of genes introduce intrinsic time delays and there is no global synchronisation among the arrival times of different molecular species at their targets. We present an experimentally implementable genetic circuit with two inputs and one output, which in the presence of small delays in input arrival, exhibits qualitatively distinct population-level phenotypes, over timescales that are longer than typical cell doubling times. From a dynamical systems point of view, these phenotypes represent long-lived transients: although they converge to the same value eventually, they do so after a very long time span. The key feature of this toy model genetic circuit is that, despite having only two inputs and one output, it is regulated by twenty-three distinct DNA-TF configurations, two of which are more stable than others (DNA looped states), one promoting and another blocking the expression of the output gene. Small delays in input arrival time result in a majority of cells in the population quickly reaching the stable state associated with the first input, while exiting of this stable state occurs at a slow timescale. In order to mechanistically model the behaviour of this genetic circuit, we used a rule-based modelling language, and implemented a grid-search to find parameter combinations giving rise to long-lived transients. Our analysis shows that in the absence of feedback, there exist path-dependent gene regulatory mechanisms based on the long timescale of transients. The behaviour of this toy model circuit suggests that gene regulatory networks can exploit event timing to create phenotypes, and it opens the possibility that they could use event timing to memorise events, without regulatory feedback. The model reveals the importance of (i) mechanistically modelling the transitions between the different DNA-TF states, and (ii) employing transient analysis thereof."}]},{"publication_status":"published","file":[{"file_id":"10105","date_updated":"2021-10-07T13:42:47Z","file_name":"2021_NewPhytologist_Han.pdf","checksum":"6422a6eb329b52d96279daaee0fcf189","file_size":1939800,"access_level":"open_access","creator":"kschuh","relation":"main_file","success":1,"date_created":"2021-10-07T13:42:47Z","content_type":"application/pdf"}],"intvolume":"       232","day":"01","ddc":["580"],"pmid":1,"project":[{"call_identifier":"H2020","_id":"261099A6-B435-11E9-9278-68D0E5697425","name":"Tracing Evolution of Auxin Transport and Polarity in Plants","grant_number":"742985"},{"call_identifier":"FWF","name":"Molecular mechanisms of endocytic cargo recognition in plants","grant_number":"I03630","_id":"26538374-B435-11E9-9278-68D0E5697425"}],"language":[{"iso":"eng"}],"month":"10","isi":1,"file_date_updated":"2021-10-07T13:42:47Z","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"},"date_updated":"2023-08-10T14:02:41Z","doi":"10.1111/nph.17617","article_processing_charge":"Yes (via OA deal)","date_published":"2021-10-01T00:00:00Z","author":[{"last_name":"Han","first_name":"Huibin","id":"31435098-F248-11E8-B48F-1D18A9856A87","full_name":"Han, Huibin"},{"full_name":"Adamowski, Maciek","id":"45F536D2-F248-11E8-B48F-1D18A9856A87","first_name":"Maciek","last_name":"Adamowski","orcid":"0000-0001-6463-5257"},{"full_name":"Qi, Linlin","id":"44B04502-A9ED-11E9-B6FC-583AE6697425","first_name":"Linlin","orcid":"0000-0001-5187-8401","last_name":"Qi"},{"full_name":"Alotaibi, SS","last_name":"Alotaibi","first_name":"SS"},{"full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jiří","last_name":"Friml","orcid":"0000-0002-8302-7596"}],"quality_controlled":"1","scopus_import":"1","type":"journal_article","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","page":"510-522","volume":232,"has_accepted_license":"1","year":"2021","_id":"9656","external_id":{"isi":["000680587100001"],"pmid":["34254313"]},"article_type":"original","issue":"2","status":"public","acknowledgement":"We are grateful to Lukas Fiedler, Alexandra Mally (IST Austria) and Dr. Bartel Vanholme (VIB, Ghent) for their critical comments on the manuscript.

In this review, we discuss recent advances concerning regulations of PIN polarity during tropisms, focusing on PIN phosphorylation and trafficking.

Similar to other organs, nodule formation is determined by a local maximum of the phytohormone auxin at the primordium site. However, how auxin regulates nodule development remains poorly understood. Here, we found that in soybean, (Glycine max), dynamic auxin transport driven by PIN-FORMED (PIN) transporter GmPIN1 is involved in nodule primordium formation. GmPIN1 was specifically expressed in nodule primordium cells and GmPIN1 was polarly localized in these cells. Two nodulation regulators, (iso)flavonoids trigger expanded distribution of GmPIN1b to root cortical cells, and cytokinin rearranges GmPIN1b polarity. Gmpin1abc triple mutants generated with CRISPR-Cas9 showed impaired establishment of auxin maxima in nodule meristems and aberrant divisions in the nodule primordium cells. Moreover, overexpression of GmPIN1 suppressed nodule primordium initiation. GmPIN9d, an ortholog of Arabidopsis thaliana PIN2, acts together with GmPIN1 later in nodule development to acropetally transport auxin in vascular bundles, fine-tuning the auxin supply for nodule enlargement. Our findings reveal how PIN-dependent auxin transport modulates different aspects of soybean nodule development and suggest that establishment of auxin gradient is a prerequisite for the proper interaction between legumes and rhizobia."}],"year":"2021","has_accepted_license":"1","_id":"9657","type":"journal_article","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","page":"2981–3003","volume":33,"publication_identifier":{"issn":["1040-4651"],"eissn":["1532-298x"]},"citation":{"ieee":"Z.

Depending on the ratio κ of the impurity and fermion masses, the billiards can be integrable or non-integrable (also referred to in the main text as chaotic). To set the stage, we first investigate the energy level distributions of the billiards as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to analyze properties of probability distributions of individual quantum states. We find that convolutional neural networks can correctly classify integrable and non-integrable states. The decisive features of the wave functions are the normalization and a large number of zero elements, corresponding to the existence of a nodal line. The network achieves typical accuracies of 97%, suggesting that machine learning tools can be used to analyze and classify the morphology of probability densities obtained in theory or experiment.","lang":"eng"}],"arxiv":1},{"tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"file_date_updated":"2022-05-13T07:40:15Z","article_number":"14","scopus_import":"1","quality_controlled":"1","date_published":"2021-08-16T00:00:00Z","author":[{"full_name":"Schmitt, Heather M.","first_name":"Heather M.","last_name":"Schmitt"},{"full_name":"Fehrman, Rachel L.","first_name":"Rachel L.","last_name":"Fehrman"},{"id":"3838F452-F248-11E8-B48F-1D18A9856A87","full_name":"Maes, Margaret E","orcid":"0000-0001-9642-1085","last_name":"Maes","first_name":"Margaret E"},{"full_name":"Yang, Huan","first_name":"Huan","last_name":"Yang"},{"full_name":"Guo, Lian Wang","last_name":"Guo","first_name":"Lian Wang"},{"first_name":"Cassandra L.","last_name":"Schlamp","full_name":"Schlamp, Cassandra L."},{"full_name":"Pelzel, Heather R.","first_name":"Heather R.","last_name":"Pelzel"},{"full_name":"Nickells, Robert W.","last_name":"Nickells","first_name":"Robert W."}],"article_processing_charge":"Yes","date_updated":"2023-08-14T06:35:17Z","doi":"10.1167/IOVS.62.10.14","intvolume":"        62","file":[{"content_type":"application/pdf","date_created":"2022-05-13T07:40:15Z","success":1,"relation":"main_file","creator":"dernst","access_level":"open_access","file_size":19707796,"checksum":"c430967746f653aa1ae84ee617f62b73","file_name":"2021_IOVS_Schmitt.pdf","file_id":"11369","date_updated":"2022-05-13T07:40:15Z"}],"publication_status":"published","isi":1,"month":"08","language":[{"iso":"eng"}],"pmid":1,"ddc":["570"],"day":"16","date_created":"2021-09-12T22:01:23Z","oa_version":"Published Version","publication":"Investigative Ophthalmology and Visual Science","department":[{"_id":"SaSi"}],"title":"Increased susceptibility and intrinsic apoptotic signaling in neurons by induced HDAC3 expression","publisher":"Association for Research in Vision and Ophthalmology","abstract":[{"lang":"eng","text":"Inhibition or targeted deletion of histone deacetylase 3 (HDAC3) is neuroprotective in a variety neurodegenerative conditions, including retinal ganglion cells (RGCs) after acute optic nerve damage.

This problem generalizes the SCC decomposition problem of graphs and closed recurrent sets of Markov chains. The model of symbolic algorithms is widely used in formal verification and model-checking, where access to the input model is restricted to only symbolic operations (e.g., basic set operations and computation of one-step neighborhood). For an input MDP with  n  vertices and  m  edges, the classical symbolic algorithm from the 1990s for the MEC decomposition requires  O(n2)  symbolic operations and  O(1)  symbolic space. The only other symbolic algorithm for the MEC decomposition requires  O(nm−−√)  symbolic operations and  O(m−−√)  symbolic space. A main open question is whether the worst-case  O(n2)  bound for symbolic operations can be beaten. We present a symbolic algorithm that requires  O˜(n1.5)  symbolic operations and  O˜(n−−√)  symbolic space. Moreover, the parametrization of our algorithm provides a trade-off between symbolic operations and symbolic space: for all  0<ϵ≤1/2  the symbolic algorithm requires  O˜(n2−ϵ)  symbolic operations and  O˜(nϵ)  symbolic space ( O˜  hides poly-logarithmic factors). Using our techniques we present faster algorithms for computing the almost-sure winning regions of  ω -regular objectives for MDPs. We consider the canonical parity objectives for  ω -regular objectives, and for parity objectives with  d -priorities we present an algorithm that computes the almost-sure winning region with  O˜(n2−ϵ)  symbolic operations and  O˜(nϵ)  symbolic space, for all  0<ϵ≤1/2 .","lang":"eng"}],"arxiv":1,"oa_version":"Preprint","ec_funded":1,"date_created":"2021-09-12T22:01:24Z","publisher":"Institute of Electrical and Electronics Engineers","department":[{"_id":"KrCh"}],"title":"Symbolic time and space tradeoffs for probabilistic verification","publication":"Proceedings of the 36th Annual ACM/IEEE Symposium on Logic in Computer Science","publication_identifier":{"issn":["1043-6871"],"eisbn":["978-1-6654-4895-6"],"isbn":["978-1-6654-4896-3"]},"citation":{"ieee":"K.
