Current techniques that allow to reduce the feature size of patterns below 1 μm are, however, often costly and require sophisticated equipment. We present here a straightforward and convenient method to generate highly condensed nanopatterns of proteins without the need for clean room facilities or expensive equipment. Our approach is based on nanocontact printing and allows for the fabrication of protein patterns with feature sizes of 80 nm and periodicities down to 140 nm. This was made possible by the use of the material X-poly(dimethylsiloxane) (X-PDMS) in a two-layer stamp layout for protein printing. In a proof of principle, different proteins at various scales were printed and the pattern quality was evaluated by atomic force microscopy (AFM) and super-resolution fluorescence microscopy.","lang":"eng"}],"month":"01","type":"journal_article","oa_version":"Published Version","intvolume":"         6","citation":{"chicago":"Lindner, Marco, Aliz Tresztenyak, Gergö Fülöp, Wiebke Jahr, Adrian Prinz, Iris Prinz, Johann G Danzl, Gerhard J.

JuliaReach consists of two main packages: Reachability, containing implementations of reachability algorithms for continuous and hybrid systems, and LazySets, a standalone library that implements state-of-the-art algorithms for calculus with convex sets. The library offers both concrete and lazy set representations, where the latter stands for the ability to delay set computations until they are needed. The choice of the programming language Julia and the accompanying documentation of our toolbox allow researchers to easily translate set-based algorithms from mathematics to software in a platform-independent way, while achieving runtime performance that is comparable to statically compiled languages. Combining lazy operations in high dimensions and explicit computations in low dimensions, JuliaReach can be applied to solve complex, large-scale problems.","lang":"eng"}],"date_updated":"2023-08-24T14:47:21Z","page":"39-44","_id":"6035","year":"2019","quality_controlled":"1","doi":"10.1145/3302504.3311804","publication_identifier":{"isbn":["9781450362825"]},"language":[{"iso":"eng"}],"keyword":["reachability analysis","hybrid systems","lazy computation"],"conference":{"name":"HSCC: Hybrid Systems Computation and Control","location":"Montreal, QC, Canada","start_date":"2019-04-16","end_date":"2019-04-18"},"isi":1,"project":[{"grant_number":"Z211","name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"name":"Rigorous Systems Engineering","call_identifier":"FWF","_id":"25832EC2-B435-11E9-9278-68D0E5697425","grant_number":"S 11407_N23"},{"name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411"}],"arxiv":1,"title":"JuliaReach: A toolbox for set-based reachability","day":"16","file":[{"checksum":"28ed56439aea5991c3122d4730fd828f","file_id":"6067","date_updated":"2020-07-14T12:47:17Z","access_level":"open_access","date_created":"2019-03-05T09:27:18Z","file_name":"hscc19.pdf","creator":"cschilli","file_size":3784414,"content_type":"application/pdf","relation":"main_file"}],"author":[{"id":"369D9A44-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0686-0365","full_name":"Bogomolov, Sergiy","last_name":"Bogomolov","first_name":"Sergiy"},{"full_name":"Forets, Marcelo","first_name":"Marcelo","last_name":"Forets"},{"full_name":"Frehse, Goran","first_name":"Goran","last_name":"Frehse"},{"full_name":"Potomkin, Kostiantyn","last_name":"Potomkin","first_name":"Kostiantyn"},{"full_name":"Schilling, Christian","id":"3A2F4DCE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3658-1065","first_name":"Christian","last_name":"Schilling"}],"scopus_import":"1","article_processing_charge":"No","ec_funded":1,"publication":"Proceedings of the 22nd International Conference on Hybrid Systems: Computation and Control","department":[{"_id":"ToHe"}],"publisher":"ACM","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8"},{"intvolume":"     11427","citation":{"apa":"Christakis, M., Heizmann, M., Mansur, M.

However, developers still spend a significant amount of time on debugging. This involves processing long error traces in an effort to localize a bug to a relatively small part of the program and to identify its cause. In this paper, we present a technique for automated fault localization that, given a program and an error trace, efficiently narrows down the cause of the error to a few statements. These statements are then ranked in terms of their suspiciousness. Our technique relies only on the semantics of the given program and does not require any test cases or user guidance. In experiments on a set of C benchmarks, we show that our technique is effective in quickly isolating the cause of error while out-performing other state-of-the-art fault-localization techniques."}],"type":"conference","month":"04","oa_version":"Published Version","isi":1,"conference":{"end_date":"2019-04-11","name":"TACAS: Tools and Algorithms for the Construction and Analysis of Systems","location":"Prague, Czech Republic","start_date":"2019-04-06"},"language":[{"iso":"eng"}],"project":[{"call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411"},{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"The Wittgenstein Prize","grant_number":"Z211"},{"grant_number":"S 11407_N23","_id":"25832EC2-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Rigorous Systems Engineering"}],"doi":"10.1007/978-3-030-17462-0_13","quality_controlled":"1","publication":"25th International Conference on Tools and Algorithms for the Construction and Analysis of Systems ","article_processing_charge":"No","ec_funded":1,"scopus_import":"1","tmp":{"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)","short":"CC BY (4.0)"},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"Springer Nature","department":[{"_id":"ToHe"}],"title":"Semantic fault localization and suspiciousness ranking","author":[{"last_name":"Christakis","first_name":"Maria","full_name":"Christakis, Maria"},{"last_name":"Heizmann","first_name":"Matthias","full_name":"Heizmann, Matthias"},{"full_name":"Mansur, Muhammad Numair","last_name":"Mansur","first_name":"Muhammad Numair"},{"first_name":"Christian","last_name":"Schilling","full_name":"Schilling, Christian","orcid":"0000-0003-3658-1065","id":"3A2F4DCE-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Valentin","last_name":"Wüstholz","full_name":"Wüstholz, Valentin"}],"day":"04","file":[{"date_created":"2019-05-10T14:16:05Z","access_level":"open_access","file_id":"6408","date_updated":"2020-07-14T12:47:17Z","checksum":"9998496f6fe202c0a19124b4209154c6","file_size":773083,"relation":"main_file","content_type":"application/pdf","creator":"dernst","file_name":"2019_LNCS_Christakis.pdf"}]},{"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"Embo Press","pmid":1,"department":[{"_id":"GaTk"}],"publication":"Molecular systems biology","article_processing_charge":"No","scopus_import":"1","author":[{"id":"39B66846-F248-11E8-B48F-1D18A9856A87","full_name":"Mitosch, Karin","first_name":"Karin","last_name":"Mitosch"},{"last_name":"Rieckh","first_name":"Georg","full_name":"Rieckh, Georg","id":"34DA8BD6-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Bollenbach","first_name":"Mark Tobias","orcid":"0000-0003-4398-476X","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","full_name":"Bollenbach, Mark Tobias"}],"day":"14","title":"Temporal order and precision of complex stress responses in individual bacteria","article_number":"e8470","project":[{"grant_number":"P27201-B22","name":"Revealing the mechanisms underlying drug interactions","call_identifier":"FWF","_id":"25E9AF9E-B435-11E9-9278-68D0E5697425"},{"name":"Revealing the fundamental limits of cell growth","_id":"25EB3A80-B435-11E9-9278-68D0E5697425","grant_number":"RGP0042/2013"}],"isi":1,"language":[{"iso":"eng"}],"issue":"2","doi":"10.15252/msb.20188470","quality_controlled":"1","year":"2019","_id":"6046","abstract":[{"lang":"eng","text":"Sudden stress often triggers diverse, temporally structured gene expression responses in microbes, but it is largely unknown how variable in time such responses are and if genes respond in the same temporal order in every single cell. Here, we quantified timing variability of individual promoters responding to sublethal antibiotic stress using fluorescent reporters, microfluidics, and time‐lapse microscopy. We identified lower and upper bounds that put definite constraints on timing variability, which varies strongly among promoters and conditions. Timing variability can be interpreted using results from statistical kinetics, which enable us to estimate the number of rate‐limiting molecular steps underlying different responses. We found that just a few critical steps control some responses while others rely on dozens of steps. To probe connections between different stress responses, we then tracked the temporal order and response time correlations of promoter pairs in individual cells. Our results support that, when bacteria are exposed to the antibiotic nitrofurantoin, the ensuing oxidative stress and SOS responses are part of the same causal chain of molecular events. In contrast, under trimethoprim, the acid stress response and the SOS response are part of different chains of events running in parallel. Our approach reveals fundamental constraints on gene expression timing and provides new insights into the molecular events that underlie the timing of stress responses."}],"date_updated":"2023-08-24T14:49:53Z","type":"journal_article","oa_version":"Submitted Version","month":"02","volume":15,"date_created":"2019-02-24T22:59:18Z","external_id":{"pmid":["30765425"],"isi":["000459628300003"]},"status":"public","intvolume":"        15","citation":{"ista":"Mitosch K, Rieckh G, Bollenbach MT. 2019.

This is simply illustrated through the mean field Landau theory whose feedback dynamics turn out to be described by the Van der Pol equation and it is then validated for the fully connected Ising model following heat bath dynamics. Despite its simplicity, this theory accounts potentially for a rich range of phenomena: here it is applied to describe in a stylized way (i) excess demand-price cycles due to strong herding in a simple agent-based market model; (ii) congestion waves in queuing networks triggered by user feedback to delays in overloaded conditions; and (iii) metabolic network oscillations resulting from cell growth control in a bistable phenotypic landscape."}],"file_date_updated":"2020-07-14T12:47:17Z","date_created":"2019-02-24T22:59:19Z","volume":52,"year":"2019","_id":"6049","quality_controlled":"1","doi":"10.1088/1751-8121/aaf2dd","project":[{"grant_number":"291734","call_identifier":"FP7","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme"}],"issue":"4","language":[{"iso":"eng"}],"isi":1,"file":[{"file_id":"6344","date_updated":"2020-07-14T12:47:17Z","checksum":"1112304ad363a6d8afaeccece36473cf","date_created":"2019-04-19T12:18:57Z","access_level":"open_access","file_name":"2019_IOP_DeMartino.pdf","file_size":1804557,"content_type":"application/pdf","relation":"main_file","creator":"kschuh"}],"day":"07","author":[{"full_name":"De Martino, Daniele","orcid":"0000-0002-5214-4706","id":"3FF5848A-F248-11E8-B48F-1D18A9856A87","first_name":"Daniele","last_name":"De Martino"}],"article_number":"045002","title":"Feedback-induced self-oscillations in large interacting systems subjected to phase transitions","department":[{"_id":"GaTk"}],"publisher":"IOP Publishing","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","tmp":{"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)","short":"CC BY (4.0)"},"ec_funded":1,"scopus_import":"1","article_processing_charge":"Yes (in subscription journal)","publication":"Journal of Physics A: Mathematical and Theoretical"},{"isi":1,"language":[{"iso":"eng"}],"doi":"10.1090/proc/14240","quality_controlled":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publisher":"AMS","department":[{"_id":"HeEd"}],"publication":"Proceedings of the American Mathematical Society","scopus_import":"1","article_processing_charge":"No","author":[{"orcid":"0000-0002-2548-617X","id":"430D2C90-F248-11E8-B48F-1D18A9856A87","full_name":"Akopyan, Arseniy","last_name":"Akopyan","first_name":"Arseniy"},{"full_name":"Fedorov, Roman","last_name":"Fedorov","first_name":"Roman"}],"day":"01","arxiv":1,"title":"Two circles and only a straightedge","external_id":{"arxiv":["1709.02562"],"isi":["000450363900008"]},"status":"public","intvolume":"       147","citation":{"short":"A.

The classic gel recipe results in an expansion factor of ~4×, with a resolution of 60–80 nm. We have recently developed X10 microscopy, which uses a gel that achieves an expansion factor of ~10×, with a resolution of ~25 nm. Here, we provide a step-by-step protocol for X10 expansion microscopy. A typical experiment consists of seven sequential stages: (i) immunostaining, (ii) anchoring, (iii) polymerization, (iv) homogenization, (v) expansion, (vi) imaging, and (vii) validation. The protocol presented here includes recommendations for optimization, pitfalls and their solutions, and detailed guidelines that should increase reproducibility. Although our protocol focuses on X10 expansion microscopy, we detail which of these suggestions are also applicable to classic fourfold expansion microscopy. We exemplify our protocol using primary hippocampal neurons from rats, but our approach can be used with other primary cells or cultured cell lines of interest. This protocol will enable any researcher with basic experience in immunostainings and access to an epifluorescence microscope to perform super-resolution microscopy with X10. The procedure takes 3 d and requires ~5 h of actively handling the sample for labeling and expansion, and another ~3 h for imaging and analysis.","lang":"eng"}],"oa_version":"Submitted Version","type":"journal_article","month":"03","_id":"6052","year":"2019"},{"day":"01","author":[{"first_name":"Mahmoud","last_name":"Kalaee","full_name":"Kalaee, Mahmoud"},{"first_name":"Mohammad","last_name":"Mirhosseini","full_name":"Mirhosseini, Mohammad"},{"full_name":"Dieterle, Paul B.","first_name":"Paul B.","last_name":"Dieterle"},{"last_name":"Peruzzo","first_name":"Matilda","full_name":"Peruzzo, Matilda","orcid":"0000-0002-3415-4628","id":"3F920B30-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink"},{"full_name":"Painter, Oskar","last_name":"Painter","first_name":"Oskar"}],"title":"Quantum electromechanics of a hypersonic crystal","department":[{"_id":"JoFi"}],"publisher":"Springer Nature","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_processing_charge":"No","scopus_import":"1","article_type":"original","publication":"Nature Nanotechnology","publication_identifier":{"issn":["1748-3387"],"eissn":["1748-3395"]},"quality_controlled":"1","doi":"10.1038/s41565-019-0377-2","language":[{"iso":"eng"}],"issue":"4","isi":1,"date_updated":"2023-08-24T14:48:08Z","abstract":[{"lang":"eng","text":"Recent technical developments in the fields of quantum electromechanics and optomechanics have spawned nanoscale mechanical transducers with the sensitivity to measure mechanical displacements at the femtometre scale and the ability to convert electromagnetic signals at the single photon level. A key challenge in this field is obtaining strong coupling between motion and electromagnetic fields without adding additional decoherence. Here we present an electromechanical transducer that integrates a high-frequency (0.42 GHz) hypersonic phononic crystal with a superconducting microwave circuit. The use of a phononic bandgap crystal enables quantum-level transduction of hypersonic mechanical motion and concurrently eliminates decoherence caused by acoustic radiation. Devices with hypersonic mechanical frequencies provide a natural pathway for integration with Josephson junction quantum circuits, a leading quantum computing technology, and nanophotonic systems capable of optical networking and distributing quantum information."}],"type":"journal_article","month":"04","oa_version":"Submitted Version","page":"334–339","date_created":"2019-02-24T22:59:21Z","volume":14,"year":"2019","_id":"6053","publication_status":"published","oa":1,"main_file_link":[{"open_access":"1","url":"https://authors.library.caltech.edu/92123/"}],"date_published":"2019-04-01T00:00:00Z","status":"public","external_id":{"isi":["000463195700014"]},"citation":{"apa":"Kalaee, M., Mirhosseini, M., Dieterle, P.

This lack of randomness is a consequential limitation, given that a wide variety of real-world financial contracts, such as casino games and lotteries, depend entirely on randomness. As a result, several ad-hoc random number generation approaches have been developed to be used in smart contracts. These include ideas such as using an oracle or relying on the block hash. However, these approaches are manipulatable, i.e. their output can be tampered with by parties who might not be neutral, such as the owner of the oracle or the miners.We propose a novel game-theoretic approach for generating provably unmanipulatable pseudorandom numbers on the blockchain. Our approach allows smart contracts to access a trustworthy source of randomness that does not rely on potentially compromised miners or oracles, hence enabling the creation of a new generation of smart contracts that are not limited to being non-probabilistic and can be drawn from the much more general class of probabilistic programs."}],"oa_version":"Preprint","month":"05","type":"conference","citation":{"ama":"Chatterjee K, Goharshady AK, Pourdamghani A.

The transport behavior of these materials is best described by low Reynolds number hydrodynamics, where the constitutive pressure–speed relation is Stoke’s law. Here we report evidence of such vortices observed in a viscous flow of Newtonian fluid in a microfluidic device consisting of a rectangular cavity—analogous to the electronic system. We extend our experimental observations to elliptic cavities of different eccentricities, and validate them by numerically solving bi-harmonic equation obtained for the viscous flow with no-slip boundary conditions. We verify the existence of a  predicted threshold at which vortices appear. Strikingly, we find that a two-dimensional theoretical model captures the essential features of three-dimensional Stokes flow in experiments.","lang":"eng"}],"date_updated":"2023-09-08T11:39:02Z","volume":10,"date_created":"2019-03-05T13:18:30Z","file_date_updated":"2020-07-14T12:47:18Z","year":"2019","_id":"6069","publication_status":"published","oa":1,"has_accepted_license":"1","ddc":["530","532"],"date_published":"2019-02-26T00:00:00Z","external_id":{"isi":["000459704600001"]},"status":"public","intvolume":"        10","citation":{"short":"J.

However, this specificity is limited, leading to frequent incorrect binding of transcription factors that might have deleterious consequences on the cell. By constructing a biophysical model of TF-DNA binding in the context of gene regulation, I will first explore how regulatory constraints can strongly shape the distribution of a population in sequence space. Then, by directly linking this to a picture of multiple types of transcription factors performing their functions simultaneously inside the cell, I will explore the extent of regulatory crosstalk -- incorrect binding interactions between transcription factors and binding sites that lead to erroneous regulatory states -- and understand the constraints this places on the design of regulatory systems. I will then develop a generic theoretical framework to investigate the coevolution of multiple transcription factors and multiple binding sites, in the context of a gene regulatory network that performs a certain function. As a particular tractable version of this problem, I will consider the evolution of two transcription factors when they transmit upstream signals to downstream target genes. Specifically, I will describe the evolutionary steady states and the evolutionary pathways involved, along with their timescales, of a system that initially undergoes a transcription factor duplication event. To connect this important theoretical model to the prominent biological event of transcription factor duplication giving rise to paralogous families, I will then describe a bioinformatics analysis of C2H2 Zn-finger transcription factors, a major family in humans, and focus on the patterns of evolution that paralogs have undergone in their various protein domains in the recent past.

However, whether this is the only signaling mode mediating lateral inhibition remains unclear. Here we show that in zebrafish oogenesis, a group of cells within the granulosa cell layer at the oocyte animal pole acquire elevated levels of the transcriptional coactivator TAZ in their nuclei. One of these cells, the future micropyle precursor cell (MPC), accumulates increasingly high levels of nuclear TAZ and grows faster than its surrounding cells, mechanically compressing those cells, which ultimately lose TAZ from their nuclei. Strikingly, relieving neighbor-cell compression by MPC ablation or aspiration restores nuclear TAZ accumulation in neighboring cells, eventually leading to MPC re-specification from these cells. Conversely, MPC specification is defective in taz−/− follicles. These findings uncover a novel mode of lateral inhibition in cell fate specification based on mechanical signals controlling TAZ activity.","lang":"eng"}],"oa_version":"Published Version","month":"03","type":"journal_article","volume":176,"date_created":"2019-03-10T22:59:19Z","status":"public","external_id":{"isi":["000460509600013"],"pmid":["30773315"]},"intvolume":"       176","related_material":{"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/in-zebrafish-eggs-most-rapidly-growing-cell-inhibits-its-neighbours-through-mechanical-signals/"}]},"citation":{"chicago":"Xia, Peng, Daniel J Gütl, Vanessa Zheden, and Carl-Philipp J Heisenberg. “Lateral Inhibition in Cell Specification Mediated by Mechanical Signals Modulating TAZ Activity.” <i>Cell</i>.

There is a crucial need for pharmacological ABCB1 and ABCG2 inhibition protocols for a more effective treatment of brain diseases. In the present study, seven marketed drugs (osimertinib, erlotinib, nilotinib, imatinib, lapatinib, pazopanib, and cyclosporine A) and one nonmarketed drug (tariquidar), with known in vitro ABCB1/ABCG2 inhibitory properties, were screened for their inhibitory potency at the BBB in vivo. Positron emission tomography (PET) using the model ABCB1/ABCG2 substrate [11C]erlotinib was performed in mice. Tested inhibitors were administered as i.v. bolus injections at 30 min before the start of the PET scan, followed by a continuous i.v. infusion for the duration of the PET scan. Five of the tested drugs increased total distribution volume of [11C]erlotinib in the brain (VT,brain) compared to vehicle-treated animals (tariquidar, + 69%; erlotinib, + 19% and +23% for the 21.5 mg/kg and the 43 mg/kg dose, respectively; imatinib, + 22%; lapatinib, + 25%; and cyclosporine A, + 49%). For all drugs, increases in [11C]erlotinib brain distribution were lower than in Abcb1a/b(−/−)Abcg2(−/−) mice (+149%), which suggested that only partial ABCB1/ABCG2 inhibition was reached at the mouse BBB. The plasma concentrations of the tested drugs at the time of the PET scan were higher than clinically achievable plasma concentrations. Some of the tested drugs led to significant increases in blood radioactivity concentrations measured at the end of the PET scan (erlotinib, + 103% and +113% for the 21.5 mg/kg and the 43 mg/kg dose, respectively; imatinib, + 125%; and cyclosporine A, + 101%), which was most likely caused by decreased hepatobiliary excretion of radioactivity. Taken together, our data suggest that some marketed tyrosine kinase inhibitors may be repurposed to inhibit ABCB1 and ABCG2 at the BBB. From a clinical perspective, moderate increases in brain delivery despite the administration of high i.v. doses as well as peripheral drug–drug interactions due to transporter inhibition in clearance organs question the translatability of this concept."}],"date_updated":"2023-08-25T08:02:51Z","type":"journal_article","month":"03","oa_version":"None","page":"1282-1293","date_created":"2019-03-10T22:59:19Z","volume":16,"status":"public","external_id":{"isi":["000460600400031"],"pmid":["30694684"]},"citation":{"chicago":"Traxl, Alexander, Severin Mairinger, Thomas Filip, Michael Sauberer, Johann Stanek, Stefan Poschner, Walter Jäger, et al. “Inhibition of ABCB1 and ABCG2 at the Mouse Blood-Brain Barrier with Marketed Drugs to Improve Brain Delivery of the Model ABCB1/ABCG2 Substrate [11C]Erlotinib.” <i>Molecular Pharmaceutics</i>.

If a mutation has opposite effects on fitness when expressed in different contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce the efficacy of selection by limiting the fixation of beneficial mutations through adaptation, and the removal of deleterious mutations through purifying selection. Although this has been widely discussed, in particular in the context of a putative “gender load,” it has yet to be systematically quantified. In this work, we empirically estimate to which extent different pleiotropic regimes impede the efficacy of selection in Drosophila melanogaster. We use whole-genome polymorphism data from a single African population and divergence data from D. simulans to estimate the fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction of selection (DoS). After controlling for confounding covariates, we find that the different pleiotropic regimes have a relatively small, but significant, effect on selection efficacy. Specifically, our results suggest that pleiotropic sexual antagonism may restrict the efficacy of selection, but that this conflict can be resolved by limiting the expression of genes to the sex where they are beneficial. Intermediate levels of pleiotropy across tissues and life stages can also lead to maladaptation in D. melanogaster, due to inefficient purifying selection combined with low frequency of mutations that confer a selective advantage. Thus, our study highlights the need to consider the efficacy of selection in the context of antagonistic pleiotropy, and of genetic conflict in general.","lang":"eng"}],"date_updated":"2024-02-21T13:59:17Z","page":"500-515","date_created":"2019-03-10T22:59:19Z","volume":36},{"quality_controlled":"1","doi":"10.1103/PhysRevE.99.022423","issue":"2","language":[{"iso":"eng"}],"isi":1,"day":"26","author":[{"full_name":"Carballo-Pacheco, Martín","last_name":"Carballo-Pacheco","first_name":"Martín"},{"full_name":"Desponds, Jonathan","first_name":"Jonathan","last_name":"Desponds"},{"full_name":"Gavrilchenko, Tatyana","last_name":"Gavrilchenko","first_name":"Tatyana"},{"first_name":"Andreas","last_name":"Mayer","full_name":"Mayer, Andreas"},{"full_name":"Prizak, Roshan","id":"4456104E-F248-11E8-B48F-1D18A9856A87","last_name":"Prizak","first_name":"Roshan"},{"full_name":"Reddy, Gautam","last_name":"Reddy","first_name":"Gautam"},{"full_name":"Nemenman, Ilya","last_name":"Nemenman","first_name":"Ilya"},{"first_name":"Thierry","last_name":"Mora","full_name":"Mora, Thierry"}],"article_number":"022423","title":"Receptor crosstalk improves concentration sensing of multiple ligands","department":[{"_id":"NiBa"},{"_id":"GaTk"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"American Physical Society","article_processing_charge":"No","scopus_import":"1","publication":"Physical Review E","oa":1,"publication_status":"published","main_file_link":[{"url":"https://www.biorxiv.org/content/10.1101/448118v1.abstract","open_access":"1"}],"date_published":"2019-02-26T00:00:00Z","external_id":{"isi":["000459916500007"]},"status":"public","citation":{"chicago":"Carballo-Pacheco, Martín, Jonathan Desponds, Tatyana Gavrilchenko, Andreas Mayer, Roshan Prizak, Gautam Reddy, Ilya Nemenman, and Thierry Mora. “Receptor Crosstalk Improves Concentration Sensing of Multiple Ligands.” <i>Physical Review E</i>.

The molecular recognition of ligands by surface receptors is degenerate in many systems, leading to crosstalk between ligand-receptor pairs. Crosstalk is often thought of as a deviation from optimal specific recognition, as the binding of noncognate ligands can interfere with the detection of the receptor's cognate ligand, possibly leading to a false triggering of a downstream signaling pathway. Here we quantify the optimal precision of sensing the concentrations of multiple ligands by a collection of promiscuous receptors. We demonstrate that crosstalk can improve precision in concentration sensing and discrimination tasks. To achieve superior precision, the additional information about ligand concentrations contained in short binding events of the noncognate ligand should be exploited. We present a proofreading scheme to realize an approximate estimation of multiple ligand concentrations that reaches a precision close to the derived optimal bounds. Our results help rationalize the observed ubiquity of receptor crosstalk in molecular sensing."}],"date_updated":"2024-02-28T13:12:06Z","date_created":"2019-03-10T22:59:20Z","volume":99,"year":"2019","_id":"6090"},{"publisher":"eLife Sciences Publications","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","department":[{"_id":"SiHi"}],"pmid":1,"publication":"eLife","tmp":{"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)","short":"CC BY (4.0)"},"scopus_import":"1","article_processing_charge":"No","author":[{"full_name":"Henderson, Nathan T.","first_name":"Nathan T.","last_name":"Henderson"},{"full_name":"Le Marchand, Sylvain J.","first_name":"Sylvain J.","last_name":"Le Marchand"},{"full_name":"Hruska, Martin","first_name":"Martin","last_name":"Hruska"},{"id":"37B36620-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2279-1061","full_name":"Hippenmeyer, Simon","first_name":"Simon","last_name":"Hippenmeyer"},{"first_name":"Liqun","last_name":"Luo","full_name":"Luo, Liqun"},{"full_name":"Dalva, Matthew B.","first_name":"Matthew B.","last_name":"Dalva"}],"day":"21","file":[{"date_created":"2019-03-11T16:15:37Z","access_level":"open_access","date_updated":"2020-07-14T12:47:19Z","file_id":"6098","checksum":"7b0800d003f14cd06b1802dea0c52941","content_type":"application/pdf","relation":"main_file","file_size":7260753,"creator":"dernst","file_name":"2019_eLife_Henderson.pdf"}],"article_number":"e41563","title":"Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs","isi":1,"language":[{"iso":"eng"}],"doi":"10.7554/eLife.41563","quality_controlled":"1","year":"2019","_id":"6091","month":"02","oa_version":"Published Version","type":"journal_article","date_updated":"2023-08-24T14:50:50Z","abstract":[{"lang":"eng","text":"Cortical networks are characterized by sparse connectivity, with synapses found at only a subset of axo-dendritic contacts. Yet within these networks, neurons can exhibit high connection probabilities, suggesting that cell-intrinsic factors, not proximity, determine connectivity. Here, we identify ephrin-B3 (eB3) as a factor that determines synapse density by mediating a cell-cell competition that requires ephrin-B-EphB signaling. In a microisland culture system designed to isolate cell-cell competition, we find that eB3 determines winning and losing neurons in a contest for synapses. In a Mosaic Analysis with Double Markers (MADM) genetic mouse model system in vivo the relative levels of eB3 control spine density in layer 5 and 6 neurons. MADM cortical neurons in vitro reveal that eB3 controls synapse density independently of action potential-driven activity. Our findings illustrate a new class of competitive mechanism mediated by trans-synaptic organizing proteins which control the number of synapses neurons receive relative to neighboring neurons."}],"volume":8,"file_date_updated":"2020-07-14T12:47:19Z","date_created":"2019-03-10T22:59:20Z","status":"public","external_id":{"isi":["000459380600001"],"pmid":["30789343"]},"intvolume":"         8","citation":{"mla":"Henderson, Nathan T., et al. “Ephrin-B3 Controls Excitatory Synapse Density through Cell-Cell Competition for EphBs.” <i>ELife</i>, vol. 8, e41563, eLife Sciences Publications, 2019, doi:<a href=\"https://doi.org/10.7554/eLife.41563\">10.7554/eLife.41563</a>.","ista":"Henderson NT, Le Marchand SJ, Hruska M, Hippenmeyer S, Luo L, Dalva MB. 2019.
