Here, we have quantitatively investigated the neuronal output of individual progenitor cells in the ventricular zone of the developing mouse neocortex using a combination of methods that together circumvent the biases and limitations of individual approaches. We found that individual cortical progenitor cells show a high degree of stochasticity and generate pyramidal cell lineages that adopt a wide range of laminar configurations. Mathematical modelling these lineage data suggests that a small number of progenitor cell populations, each generating pyramidal cells following different stochastic developmental programs, suffice to generate the heterogenous complement of pyramidal cell lineages that collectively build the complex cytoarchitecture of the neocortex."}],"citation":{"apa":"Llorca, A., Ciceri, G., Beattie, R.

These proteins are bright, but exhibit several drawbacks such as relatively large size, oxygen-dependence, sensitivity to low pH, and limited switching speed. Therefore, RSFPs from other origins with improved properties need to be explored. Here, we report the development of two RSFPs based on the LOV domain of the photoreceptor protein YtvA from Bacillus subtilis. LOV domains obtain their fluorescence by association with the abundant cellular cofactor flavin mononucleotide (FMN). Under illumination with blue and ultraviolet light, they undergo a photocycle, making these proteins inherently photoswitchable. Our first improved variant, rsLOV1, can be used for RESOLFT imaging, whereas rsLOV2 proved useful for STED nanoscopy of living cells with a resolution of down to 50 nm. In addition to their smaller size compared to GFP-related proteins (17 kDa instead of 27 kDa) and their usability at low pH, rsLOV1 and rsLOV2 exhibit faster switching kinetics, switching on and off 3 times faster than rsEGFP2, the fastest-switching RSFP reported to date. Therefore, LOV-domain-based RSFPs have potential for applications where the switching speed of GFP-based proteins is limiting.","lang":"eng"}],"article_number":"2724","year":"2018","citation":{"ama":"Gregor C, Sidenstein SC, Andresen M, Sahl SJ, Danzl JG, Hell SW.

We find that the expectations are essentially the same as for the Poisson–Delaunay mosaic in n-dimensional Euclidean space. Assuming the points are not contained in a hemisphere, the Delaunay mosaic is isomorphic to the boundary complex of the convex hull in Rn+1, so we also get the expected number of faces of a random inscribed polytope. As proved in Antonelli et al. [Adv. in Appl. Probab. 9–12 (1977–1980)], an orthant section of the n-sphere is isometric to the standard n-simplex equipped with the Fisher information metric.

However, little is known about systemic regulators that could allow the acquisition of these mechanisms. We performed a genetic screen in Drosophila melanogaster to identify regulators of germband invasion by embryonic macrophages into the confined space between the ectoderm and mesoderm. We have found that bZIP circadian transcription factors (TFs) Kayak (dFos) and Vrille (dNFIL3) have opposite effects on macrophage germband infiltration: Kayak facilitated and Vrille inhibited it. These TFs are enriched in the macrophages during migration and genetically interact to control it. Kayak sets a less coordinated mode of migration of the macrophage group and increases the probability and length of Levy walks. Intriguingly, the motility of kayak mutant macrophages was also strongly affected during initial germband invasion but not along another less confined route. Inhibiting Rho1 signaling within the tail ectoderm partially rescued the Kayak mutant phenotype, strongly suggesting that migrating macrophages have to overcome a barrier imposed by the stiffness of the ectoderm. Also, Kayak appeared to be important for the maintenance of the round cell shape and the rear edge translocation of the macrophages invading the germband. Complementary to this, the cortical actin cytoskeleton of Kayak- deficient macrophages was strongly affected. RNA sequencing revealed the filamin Cheerio and tetraspanin TM4SF to be downstream of Kayak. Chromatin immunoprecipitation and immunostaining revealed that the formin Diaphanous is another downstream target of Kayak. Immunostaining revealed that the formin Diaphanous is another downstream target of Kayak. Indeed, Cheerio, TM4SF and Diaphanous are required within macrophages for germband invasion, and expression of constitutively active Diaphanous in macrophages was able to rescue the kayak mutant phenotype. Moreover, Cher and Diaphanous are also reduced in the macrophages overexpressing Vrille. We hypothesize that Kayak, through its targets, increases actin polymerization and cortical tension in macrophages and thus allows extra force generation necessary for macrophage dissemination and migration through confined stiff tissues, while Vrille counterbalances it."}],"year":"2018","citation":{"ista":"Belyaeva V. 2018.

In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We performed a microarray-based approach to find regulators of the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs (PATL). Here, we show that PATLs are expressed in partially overlapping cells types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia, and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests PATLs redundantly play a crucial role in polarity and patterning in Arabidopsis.","lang":"eng"}],"type":"journal_article","date_published":"2018-01-29T00:00:00Z","external_id":{"isi":["000424842400019"]},"publisher":"Company of Biologists","isi":1,"month":"01","publist_id":"6530","status":"public","ddc":["581"],"language":[{"iso":"eng"}],"quality_controlled":"1","day":"29","issue":"2","has_accepted_license":"1","project":[{"call_identifier":"FP7","grant_number":"282300","name":"Polarity and subcellular dynamics in plants","_id":"25716A02-B435-11E9-9278-68D0E5697425"}],"pubrep_id":"988"},{"author":[{"last_name":"Danzl","first_name":"Johann G","full_name":"Danzl, Johann G","id":"42EFD3B6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8559-3973"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","volume":4,"oa":1,"intvolume":"         4","department":[{"_id":"JoDa"}],"date_updated":"2021-12-03T07:31:05Z","publication":"Opera Medica et Physiologica","scopus_import":"1","main_file_link":[{"open_access":"1","url":"http://operamedphys.org/content/molecular-and-cellular-neuroscience"}],"doi":"10.20388/omp2018.00s1.001","publication_identifier":{"issn":["2500-2287"],"eissn":["2500-2295"]},"article_type":"letter_note","publication_status":"published","title":"Diffraction-unlimited optical imaging for synaptic physiology","oa_version":"Published Version","article_processing_charge":"No","citation":{"mla":"Danzl, Johann G. “Diffraction-Unlimited Optical Imaging for Synaptic Physiology.” <i>Opera Medica et Physiologica</i>, vol. 4, no.

Its underlying protocol (Nakamoto consensus) achieves this by using proof of work, which has the drawback that it causes the consumption of vast amounts of energy to maintain the ledger. Moreover, Bitcoin mining dynamics have become less distributed over time.\r\n\r\nTowards addressing these issues, we propose SpaceMint, a cryptocurrency based on proofs of space instead of proofs of work. Miners in SpaceMint dedicate disk space rather than computation. We argue that SpaceMint’s design solves or alleviates several of Bitcoin’s issues: most notably, its large energy consumption. SpaceMint also rewards smaller miners fairly according to their contribution to the network, thus incentivizing more distributed participation.\r\n\r\nThis paper adapts proof of space to enable its use in cryptocurrency, studies the attacks that can arise against a Bitcoin-like blockchain that uses proof of space, and proposes a new blockchain format and transaction types to address these attacks. Our prototype shows that initializing 1 TB for mining takes about a day (a one-off setup cost), and miners spend on average just a fraction of a second per block mined. Finally, we provide a game-theoretic analysis modeling SpaceMint as an extensive game (the canonical game-theoretic notion for games that take place over time) and show that this stylized game satisfies a strong equilibrium notion, thereby arguing for SpaceMint ’s stability and consensus."}],"title":"SpaceMint: A cryptocurrency based on proofs of space","publication_status":"published","article_processing_charge":"No","oa_version":"Submitted Version","scopus_import":"1","main_file_link":[{"url":"https://eprint.iacr.org/2015/528","open_access":"1"}],"doi":"10.1007/978-3-662-58387-6_26","publication_identifier":{"issn":["0302-9743"],"eissn":["1611-3349"],"isbn":["9783662583869","9783662583876"]}},{"department":[{"_id":"SyCr"}],"ec_funded":1,"date_updated":"2023-10-17T11:50:05Z","publication":"Science","intvolume":"       362","volume":362,"oa":1,"related_material":{"record":[{"id":"13055","status":"public","relation":"research_data"}],"link":[{"url":"https://ist.ac.at/en/news/for-ants-unity-is-strength-and-health/","description":"News on IST Homepage","relation":"press_release"}]},"author":[{"first_name":"Nathalie","last_name":"Stroeymeyt","full_name":"Stroeymeyt, Nathalie"},{"full_name":"Grasse, Anna V","id":"406F989C-F248-11E8-B48F-1D18A9856A87","last_name":"Grasse","first_name":"Anna V"},{"last_name":"Crespi","first_name":"Alessandro","full_name":"Crespi, Alessandro"},{"full_name":"Mersch, Danielle","first_name":"Danielle","last_name":"Mersch"},{"first_name":"Sylvia","last_name":"Cremer","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868","full_name":"Cremer, Sylvia"},{"full_name":"Keller, Laurent","first_name":"Laurent","last_name":"Keller"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2018-12-11T11:44:07Z","_id":"7","citation":{"ama":"Stroeymeyt N, Grasse AV, Crespi A, Mersch D, Cremer S, Keller L.

Social animals could potentially further reduce epidemic risk by altering their social networks in the presence of pathogens, yet there is currently no evidence for such pathogen-triggered responses. We tested this hypothesis experimentally in the ant Lasius niger using a combination of automated tracking, controlled pathogen exposure, transmission quantification, and temporally explicit simulations. Pathogen exposure induced behavioral changes in both exposed ants and their nestmates, which helped contain the disease by reinforcing key transmission-inhibitory properties of the colony's contact network. This suggests that social network plasticity in response to pathogens is an effective strategy for mitigating the effects of disease in social groups.","lang":"eng"}],"publication_status":"published","title":"Social network plasticity decreases disease transmission in a eusocial insect","oa_version":"Published Version","article_processing_charge":"No","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://serval.unil.ch/resource/serval:BIB_E9228C205467.P001/REF.pdf"}],"doi":"10.1126/science.aat4793","acknowledgement":"This project was funded by two European Research Council Advanced Grants (Social Life, 249375, and resiliANT, 741491) and two Swiss National Science Foundation grants (CR32I3_141063 and 310030_156732) to L.K. and a European Research Council Starting Grant (SocialVaccines, 243071) to S.C.","publication_identifier":{"issn":["1095-9203"]},"article_type":"original","isi":1,"month":"11","publist_id":"8049","status":"public","language":[{"iso":"eng"}],"type":"journal_article","date_published":"2018-11-23T00:00:00Z","external_id":{"isi":["000451124500041"]},"publisher":"AAAS","issue":"6417","project":[{"call_identifier":"FP7","grant_number":"243071","name":"Social Vaccination in Ant Colonies: from Individual Mechanisms to Society Effects","_id":"25DC711C-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","page":"941 - 945","day":"23"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"id":"4BF426E2-F248-11E8-B48F-1D18A9856A87","full_name":"Nejjar, Peter","first_name":"Peter","last_name":"Nejjar"}],"oa":1,"volume":15,"intvolume":"        15","arxiv":1,"publication":"Latin American Journal of Probability and Mathematical Statistics","ec_funded":1,"date_updated":"2023-10-10T13:11:29Z","department":[{"_id":"LaEr"},{"_id":"JaMa"}],"article_type":"original","publication_identifier":{"issn":["1980-0436"]},"doi":"10.30757/ALEA.v15-49","scopus_import":"1","file_date_updated":"2020-07-14T12:47:46Z","article_processing_charge":"No","oa_version":"Published Version","publication_status":"published","title":"Transition to shocks in TASEP and decoupling of last passage times","abstract":[{"lang":"eng","text":"We consider the totally asymmetric simple exclusion process in a critical scaling parametrized by a≥0, which creates a shock in the particle density of order aT−1/3, T the observation time.

In order to understand precise functions of pre- or postsynaptic dopamine receptors (DRs), the development of protocols to differentiate pre- and postsynaptic DRs is essential. So far, most studies on determination and quantification of DRs did not discriminate between subsynaptic localization. Therefore, the aim of the study was to generate a robust workflow for the localization of DRs. This work provides the basis for future work on hippocampal DRs, in light that DRs may have different functions at pre- or postsynaptic sites. Synaptosomes from rat hippocampi isolated by a sucrose gradient protocol were prepared for super-resolution direct stochastic optical reconstruction microscopy (dSTORM) using Bassoon as a presynaptic zone and Homer1 as postsynaptic density marker. Direct labeling of primary validated antibodies against dopamine receptors D1 (D1R) and D2 (D2R) with Alexa Fluor 594 enabled unequivocal assignment of D1R and D2R to both, pre- and postsynaptic sites. D1R immunoreactivity clusters were observed within the presynaptic active zone as well as at perisynaptic sites at the edge of the presynaptic active zone. The results may be useful for the interpretation of previous studies and the design of future work on DRs in the hippocampus. Moreover, the reduction of the complexity of brain tissue by the use of synaptosomal preparations and dSTORM technology may represent a useful tool for synaptic localization of brain proteins.","lang":"eng"}],"year":"2018","citation":{"short":"A.

In particular, there has been intensive research on reducing the communication cost of training when using multiple computational devices, through reducing the precision of the underlying data representation. Naturally, such methods induce system trade-offs—lowering communication precision could de-crease communication overheads and improve scalability; but, on the other hand, it can also reduce the accuracy of training. In this paper, we study this trade-off space, and ask:Can low-precision communication consistently improve the end-to-end performance of training modern neural networks, with no accuracy loss?From the performance point of view, the answer to this question may appear deceptively easy: compressing communication through low precision should help when the ratio between communication and computation is high. However, this answer is less straightforward when we try to generalize this principle across various neural network architectures (e.g., AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g., EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL), and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is not clear how a realistic realization of all these factors maps to the speed up provided by low-precision communication. In this paper, we conduct an empirical study to answer this question and report the insights."}],"publication_status":"published","title":"Synchronous multi-GPU training for deep learning with low-precision communications: An empirical study","article_processing_charge":"No","oa_version":"Published Version","file_date_updated":"2020-07-14T12:47:49Z","scopus_import":1,"doi":"10.5441/002/EDBT.2018.14","publication_identifier":{"isbn":["9783893180783"],"issn":["2367-2005"]},"month":"03","status":"public","ddc":["000"],"language":[{"iso":"eng"}],"type":"conference","date_published":"2018-03-26T00:00:00Z","publisher":"OpenProceedings","tmp":{"image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"has_accepted_license":"1","quality_controlled":"1","page":"145-156","day":"26"},{"month":"01","isi":1,"status":"public","language":[{"iso":"eng"}],"date_published":"2018-01-30T00:00:00Z","external_id":{"arxiv":["1704.04947"],"isi":["000483921200145"]},"type":"conference","publisher":"ACM","quality_controlled":"1","page":"2221-2239","day":"30","department":[{"_id":"DaAl"}],"publication":"Proceedings of the 29th Annual ACM-SIAM Symposium on Discrete Algorithms","date_updated":"2023-09-19T15:03:16Z","arxiv":1,"oa":1,"author":[{"id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3650-940X","full_name":"Alistarh, Dan-Adrian","first_name":"Dan-Adrian","last_name":"Alistarh"},{"last_name":"Aspnes","first_name":"James","full_name":"Aspnes, James"},{"last_name":"Gelashvili","first_name":"Rati","full_name":"Gelashvili, Rati"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","conference":{"location":"New Orleans, LA, United States","name":"SODA: Symposium on Discrete Algorithms","end_date":"2018-01-10","start_date":"2018-01-07"},"_id":"7123","date_created":"2019-11-26T15:10:55Z","year":"2018","citation":{"chicago":"Alistarh, Dan-Adrian, James Aspnes, and Rati Gelashvili. “Space-Optimal Majority in Population Protocols.” In <i>Proceedings of the 29th Annual ACM-SIAM Symposium on Discrete Algorithms</i>, 2221–39.

Inspired by recent developments in DNA programming, an extensive series of papers, across different communities, has examined the computability and complexity characteristics of this model. Majority, or consensus, is a central task in this model, in which agents need to collectively reach a decision as to which one of two states A or B had a higher initial count. Two metrics are important: the time that a protocol requires to stabilize to an output decision, and the state space size that each agent requires to do so. It is known that majority requires Ω(log log n) states per agent to allow for fast (poly-logarithmic time) stabilization, and that O(log2 n) states are sufficient. Thus, there is an exponential gap between the space upper and lower bounds for this problem. This paper addresses this question.\r\n\r\nOn the negative side, we provide a new lower bound of Ω(log n) states for any protocol which stabilizes in O(n1–c) expected time, for any constant c > 0. This result is conditional on monotonicity and output assumptions, satisfied by all known protocols. Technically, it represents a departure from previous lower bounds, in that it does not rely on the existence of dense configurations. Instead, we introduce a new generalized surgery technique to prove the existence of incorrect executions for any algorithm which would contradict the lower bound. Subsequently, our lower bound also applies to general initial configurations, including ones with a leader. On the positive side, we give a new algorithm for majority which uses O(log n) states, and stabilizes in O(log2 n) expected time. Central to the algorithm is a new leaderless phase clock technique, which allows agents to synchronize in phases of Θ(n log n) consecutive interactions using O(log n) states per agent, exploiting a new connection between population protocols and power-of-two-choices load balancing mechanisms. We also employ our phase clock to build a leader election algorithm with a state space of size O(log n), which stabilizes in O(log2 n) expected time.","lang":"eng"}],"publication_status":"published","title":"Space-optimal majority in population protocols","article_processing_charge":"No","oa_version":"Preprint","doi":"10.1137/1.9781611975031.144","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1704.04947"}],"publication_identifier":{"isbn":["9781611975031"]}},{"author":[{"first_name":"Pietro","last_name":"Oliveto","full_name":"Oliveto, Pietro"},{"last_name":"Paixao","first_name":"Tiago","full_name":"Paixao, Tiago","id":"2C5658E6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2361-3953"},{"first_name":"Jorge","last_name":"Pérez Heredia","full_name":"Pérez Heredia, Jorge"},{"full_name":"Sudholt, Dirk","last_name":"Sudholt","first_name":"Dirk"},{"full_name":"Trubenova, Barbora","orcid":"0000-0002-6873-2967","id":"42302D54-F248-11E8-B48F-1D18A9856A87","last_name":"Trubenova","first_name":"Barbora"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","volume":80,"oa":1,"intvolume":"        80","department":[{"_id":"NiBa"},{"_id":"CaGu"}],"ec_funded":1,"date_updated":"2023-09-11T14:11:35Z","publication":"Algorithmica","scopus_import":"1","doi":"10.1007/s00453-017-0369-2","title":"How to escape local optima in black box optimisation when non elitism outperforms elitism","publication_status":"published","oa_version":"Published Version","article_processing_charge":"No","file_date_updated":"2020-07-14T12:47:54Z","citation":{"short":"P.

Using the metaphor of a fitness landscape, local optima correspond to hills separated by fitness valleys that have to be overcome. We define a class of fitness valleys of tunable difficulty by considering their length, representing the Hamming path between the two optima and their depth, the drop in fitness. For this function class we present a runtime comparison between stochastic search algorithms using different search strategies. The (1+1) EA is a simple and well-studied evolutionary algorithm that has to jump across the valley to a point of higher fitness because it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population genetics, are both able to cross the fitness valley by accepting worsening moves. We show that the runtime of the (1+1) EA depends critically on the length of the valley while the runtimes of the non-elitist algorithms depend crucially on the depth of the valley. Moreover, we show that both SSWM and Metropolis can also efficiently optimise a rugged function consisting of consecutive valleys."}],"date_created":"2018-12-11T11:48:09Z","file":[{"content_type":"application/pdf","creator":"system","file_id":"4674","checksum":"7d92f5d7be81e387edeec4f06442791c","access_level":"open_access","file_name":"IST-2018-1014-v1+1_2018_Paixao_Escape.pdf","date_created":"2018-12-12T10:08:14Z","relation":"main_file","date_updated":"2020-07-14T12:47:54Z","file_size":691245}],"_id":"723","publisher":"Springer","type":"journal_article","date_published":"2018-05-01T00:00:00Z","external_id":{"isi":["000428239300010"]},"ddc":["576"],"language":[{"iso":"eng"}],"isi":1,"month":"05","publist_id":"6957","status":"public","page":"1604 - 1633","day":"01","quality_controlled":"1","pubrep_id":"1014","issue":"5","project":[{"_id":"25B1EC9E-B435-11E9-9278-68D0E5697425","name":"Speed of Adaptation in Population Genetics and Evolutionary Computation","grant_number":"618091","call_identifier":"FP7"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"has_accepted_license":"1"},{"quality_controlled":"1","day":"01","page":"166 - 207","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"has_accepted_license":"1","project":[{"grant_number":"S 11407_N23","call_identifier":"FWF","name":"Rigorous Systems Engineering","_id":"25832EC2-B435-11E9-9278-68D0E5697425"},{"name":"Game Theory","_id":"25863FF4-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"S11407"},{"name":"Modern Graph Algorithmic Techniques in Formal Verification","_id":"2584A770-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"P 23499-N23"},{"call_identifier":"FP7","grant_number":"279307","name":"Quantitative Graph Games: Theory and Applications","_id":"2581B60A-B435-11E9-9278-68D0E5697425"},{"_id":"2587B514-B435-11E9-9278-68D0E5697425","name":"Microsoft Research Faculty Fellowship"}],"issue":"1","pubrep_id":"960","external_id":{"isi":["000419955500006"]},"date_published":"2018-01-01T00:00:00Z","type":"journal_article","publisher":"Springer","status":"public","publist_id":"6929","month":"01","isi":1,"language":[{"iso":"eng"}],"ddc":["000"],"file_date_updated":"2020-07-14T12:47:56Z","article_processing_charge":"No","oa_version":"Published Version","publication_status":"published","title":"Automated competitive analysis of real time scheduling with graph games","doi":"10.1007/s11241-017-9293-4","scopus_import":"1","_id":"738","file":[{"date_updated":"2020-07-14T12:47:56Z","relation":"main_file","date_created":"2018-12-12T10:17:14Z","file_size":1163507,"file_name":"IST-2018-960-v1+1_2017_Chatterjee_Automated_competetive.pdf","access_level":"open_access","checksum":"c2590ef160709d8054cf29ee173f1454","content_type":"application/pdf","creator":"system","file_id":"5267"}],"date_created":"2018-12-11T11:48:14Z","abstract":[{"lang":"eng","text":"This paper is devoted to automatic competitive analysis of real-time scheduling algorithms for firm-deadline tasksets, where only completed tasks con- tribute some utility to the system.

Our approach is flexible as it also provides ways to model meaningful constraints on the released task sequences that determine the competitive ratio. We provide an experimental study of many well-known on-line scheduling algorithms, which demonstrates the feasibility of our competitive analysis approach that effectively replaces human ingenuity (required Preliminary versions of this paper have appeared in Chatterjee et al.

For the competitive synthesis case, we are just given a taskset T , and the goal is to automatically synthesize an opti- mal on-line scheduling algorithm A , i.e., one that guarantees the largest competitive ratio possible for T . We show how the competitive synthesis problem can be reduced to a two-player graph game with partial information, and establish that the compu- tational complexity of solving this game is Np -complete. The competitive synthesis problem is hence in Np in the size of the state space of the non-deterministic labeled transition system encoding the taskset. Overall, the proposed framework assists in the selection of suitable scheduling algorithms for a given taskset, which is in fact the most common situation in real-time systems design.

PoS were introduced as a more ecological and economical replacement for proofs of work which are currently used to secure blockchains like Bitcoin. In this work we investigate extensions of PoS which allow the prover to embed useful data into the dedicated space, which later can be recovered. Our first contribution is a security proof for the original PoS from CRYPTO'15 in the random oracle model (the original proof only applied to a restricted class of adversaries which can store a subset of the data an honest prover would store). When this PoS is instantiated with recent constructions of maximally depth robust graphs, our proof implies basically optimal security. As a second contribution we show three different extensions of this PoS where useful data can be embedded into the space required by the prover. Our security proof for the PoS extends (non-trivially) to these constructions. We discuss how some of these variants can be used as proofs of catalytic space (PoCS), a notion we put forward in this work, and which basically is a PoS where most of the space required by the prover can be used to backup useful data. Finally we discuss how one of the extensions is a candidate construction for a proof of replication (PoR), a proof system recently suggested in the Filecoin whitepaper.
