The more recent concept of differential privacy, introduced by the cryptographic community, is an approach which provides a rigorous definition of privacy with meaningful privacy guarantees in the presence of arbitrary external information, although the guarantees may come at a serious price in terms of data utility. Building on such notions, we propose new methods to release aggregate GWAS data without compromising an individual’s privacy. We present methods for releasing differentially private minor allele frequencies, chi-square statistics and p-values. We compare these approaches on simulated data and on a GWAS study of canine hair length involving 685 dogs. We also propose a privacy-preserving method for finding genome-wide associations based on a differentially-private approach to penalized logistic regression.","lang":"eng"}],"oa_version":"Published Version","month":"08","publication":"Journal of Privacy and Confidentiality ","year":"2013","language":[{"iso":"eng"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","day":"01","publist_id":"5067","publication_status":"published","oa":1,"date_updated":"2021-01-12T06:54:41Z","main_file_link":[{"url":"http://repository.cmu.edu/jpc/vol5/iss1/6","open_access":"1"}],"citation":{"ieee":"C.

The main justification for imposing this assumption is that the set of unfaithful distributions has Lebesgue measure zero, since it can be seen as a collection of hypersurfaces in a hypercube. However, due to sampling error the faithfulness condition alone is not sufficient for statistical estimation, and strong-faithfulness has been proposed and assumed to achieve uniform or high-dimensional consistency. In contrast to the plain faithfulness assumption, the set of distributions that is not strong-faithful has nonzero Lebesgue measure and in fact, can be surprisingly large as we show in this paper. We study the strong-faithfulness condition from a geometric and combinatorial point of view and give upper and lower bounds on the Lebesgue measure of strong-faithful distributions for various classes of directed acyclic graphs. Our results imply fundamental limitations for the PC-algorithm and potentially also for other algorithms based on partial correlation testing in the Gaussian case.","lang":"eng"}],"volume":41,"date_published":"2013-04-01T00:00:00Z","issue":"2","publication":"The Annals of Statistics","day":"01","year":"2013","language":[{"iso":"eng"}],"title":"Geometry of the faithfulness assumption in causal inference","status":"public","type":"journal_article","citation":{"short":"C.

Better performance may be achieved at the expense of relaxing correctness, by redefining the semantics of data structures. We address such a redefinition of data structure semantics and present a systematic and formal framework for obtaining new data structures by quantitatively relaxing existing ones. We view a data structure as a sequential specification S containing all &quot;legal&quot; sequences over an alphabet of method calls. Relaxing the data structure corresponds to defining a distance from any sequence over the alphabet to the sequential specification: the k-relaxed sequential specification contains all sequences over the alphabet within distance k from the original specification. In contrast to other existing work, our relaxations are semantic (distance in terms of data structure states). As an instantiation of our framework, we present two simple yet generic relaxation schemes, called out-of-order and stuttering relaxation, along with several ways of computing distances. We show that the out-of-order relaxation, when further instantiated to stacks, queues, and priority queues, amounts to tolerating bounded out-of-order behavior, which cannot be captured by a purely syntactic relaxation (distance in terms of sequence manipulation, e.g. edit distance). We give concurrent implementations of relaxed data structures and demonstrate that bounded relaxations provide the means for trading correctness for performance in a controlled way. The relaxations are monotonic which further highlights the trade-off: increasing k increases the number of permitted sequences, which as we demonstrate can lead to better performance. Finally, since a relaxed stack or queue also implements a pool, we actually have new concurrent pool implementations that outperform the state-of-the-art ones.","lang":"eng"}],"author":[{"id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A","orcid":"0000−0002−2985−7724","last_name":"Henzinger","first_name":"Thomas A"},{"last_name":"Kirsch","first_name":"Christoph","full_name":"Kirsch, Christoph"},{"first_name":"Hannes","last_name":"Payer","full_name":"Payer, Hannes"},{"first_name":"Ali","last_name":"Sezgin","full_name":"Sezgin, Ali","id":"4C7638DA-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Ana","last_name":"Sokolova","full_name":"Sokolova, Ana"}],"file_date_updated":"2020-07-14T12:45:31Z","department":[{"_id":"ToHe"}],"quality_controlled":"1","acknowledgement":" and an Elise Richter Fellowship (Austrian Science Fund V00125).

Our framework provides a systematic way for counter-example guided abstraction refinement for quantitative properties. The salient aspect of the framework is that it allows anytime verification, that is, verification algorithms that can be stopped at any time (for example, due to exhaustion of memory), and report approximations that improve monotonically when the algorithms are given more time. We instantiate the framework with a number of quantitative abstractions and refinement schemes, which differ in terms of how much quantitative information they keep from the original system. We introduce both state-based and trace-based quantitative abstractions, and we describe conditions that define classes of quantitative properties for which the abstractions provide over-approximations. We give algorithms for evaluating the quantitative properties on the abstract systems. We present algorithms for counter-example based refinements for quantitative properties for both state-based and segment-based abstractions. We perform a case study on worst-case execution time of executables to evaluate the anytime verification aspect and the quantitative abstractions we proposed."}],"date_published":"2013-01-01T00:00:00Z","author":[{"first_name":"Pavol","last_name":"Cerny","full_name":"Cerny, Pavol","id":"4DCBEFFE-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Thomas A","last_name":"Henzinger","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"id":"3B51CAC4-F248-11E8-B48F-1D18A9856A87","full_name":"Radhakrishna, Arjun","last_name":"Radhakrishna","first_name":"Arjun"}],"date_updated":"2021-01-12T06:55:50Z","ec_funded":1,"publication_status":"published","conference":{"location":"Rome, Italy","end_date":"2013-01-25","name":"POPL: Principles of Programming Languages","start_date":"2013-07-23"},"publist_id":"4800","day":"01","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"year":"2013","publication":"Proceedings of the 40th annual ACM SIGPLAN-SIGACT symposium on Principles of programming language","oa_version":"None","month":"01","type":"conference","status":"public","scopus_import":1,"title":"Quantitative abstraction refinement","publisher":"ACM","citation":{"mla":"Cerny, Pavol, et al. “Quantitative Abstraction Refinement.” <i>Proceedings of the 40th Annual ACM SIGPLAN-SIGACT Symposium on Principles of Programming Language</i>, ACM, 2013, pp. 115–28, doi:<a href=\"https://doi.org/10.1145/2429069.2429085\">10.1145/2429069.2429085</a>.","apa":"Cerny, P., Henzinger, T.

We consider a generalised version of discounted reward objectives, in which the amount of discounting depends on the states visited and on the objective. This definition extends the usual definition of discounted reward, and allows to capture the systems in which the value of different commodities diminish at different and variable rates.\r\n\r\nWe establish results for two prominent subclasses of the problem, namely state-discount models where the discount factors are only dependent on the state of the MDP (and independent of the objective), and reward-discount models where they are only dependent on the objective (but not on the state of the MDP). For the state-discount models we use a straightforward reduction to expected total reward and show that the problem whether a value is achievable can be solved in polynomial time. For the reward-discount model we show that memory and randomisation of the strategies are required, but nevertheless that the problem is decidable and it is sufficient to consider strategies which after a certain number of steps behave in a memoryless way.\r\n\r\nFor the general case, we show that when restricted to graphs (i.e. MDPs with no randomisation), pure strategies and discount factors of the form 1/n where n is an integer, the problem is in PSPACE and finite memory suffices for achieving a given value. We also show that when the discount factors are not of the form 1/n, the memory required by a strategy can be infinite.\r\n"}],"volume":8312,"date_published":"2013-12-01T00:00:00Z","author":[{"orcid":"0000-0002-4561-241X","last_name":"Chatterjee","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Forejt, Vojtěch","first_name":"Vojtěch","last_name":"Forejt"},{"first_name":"Dominik","last_name":"Wojtczak","full_name":"Wojtczak, Dominik"}],"ec_funded":1,"day":"01","year":"2013","language":[{"iso":"eng"}],"series_title":"Lecture Notes in Computer Science","scopus_import":1,"publisher":"Springer","project":[{"call_identifier":"FP7","grant_number":"279307","_id":"2581B60A-B435-11E9-9278-68D0E5697425","name":"Quantitative Graph Games: Theory and Applications"}],"date_created":"2018-12-11T11:56:30Z"},{"has_accepted_license":"1","alternative_title":["LIPIcs"],"month":"09","oa_version":"Published Version","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publist_id":"4708","conference":{"name":"CSL: Computer Science Logic","start_date":"2013-09-02","end_date":"2013-09-05","location":"Torino, Italy"},"oa":1,"publication_status":"published","ddc":["000","004"],"date_updated":"2020-08-11T10:09:42Z","citation":{"mla":"Michaliszyn, Jakub, and Jan Otop. <i>Elementary Modal Logics over Transitive Structures</i>.

We want to &quot;untangle&quot; the βj from the αi by a self-homeomorphism of ℳ; more precisely, we seek an homeomorphism φ: ℳ → ℳ fixing the boundary of ℳ pointwise such that the total number of crossings of the αi with the φ(βj) is as small as possible. This problem is motivated by an application in the algorithmic theory of embeddings and 3-manifolds. We prove that if ℳ is planar, i.e., a sphere with h ≥ 0 boundary components (&quot;holes&quot;), then O(mn) crossings can be achieved (independently of h), which is asymptotically tight, as an easy lower bound shows. In general, for an arbitrary (orientable or nonorientable) surface ℳ with h holes and of (orientable or nonorientable) genus g ≥ 0, we obtain an O((m + n)4) upper bound, again independent of h and g.

Here we study direct reciprocity in the context of the alternating Prisoner's Dilemma. We consider all strategies that can be implemented by one and two-state automata. We calculate the payoff matrix of all pairwise encounters in the presence of noise. We explore deterministic selection dynamics with and without mutation. Using different error rates and payoff values, we observe convergence to a small number of distinct equilibria. Two of them are uncooperative strict Nash equilibria representing always-defect (ALLD) and Grim. The third equilibrium is mixed and represents a cooperative alliance of several strategies, dominated by a strategy which we call Forgiver. Forgiver cooperates whenever the opponent has cooperated; it defects once when the opponent has defected, but subsequently Forgiver attempts to re-establish cooperation even if the opponent has defected again. Forgiver is not an evolutionarily stable strategy, but the alliance, which it rules, is asymptotically stable. For a wide range of parameter values the most commonly observed outcome is convergence to the mixed equilibrium, dominated by Forgiver. Our results show that although forgiving might incur a short-term loss it can lead to a long-term gain. Forgiveness facilitates stable cooperation in the presence of exploitation and noise."}],"file_date_updated":"2020-07-14T12:45:34Z","issue":"12","ec_funded":1,"publication":"PLoS One","year":"2013","language":[{"iso":"eng"}],"day":"12","title":"Forgiver triumphs in alternating prisoner's dilemma ","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"pubrep_id":"409","type":"journal_article","status":"public","citation":{"mla":"Zagorsky, Benjamin, et al. “Forgiver Triumphs in Alternating Prisoner’s Dilemma .” <i>PLoS One</i>, vol. 8, no. 12, e80814, Public Library of Science, 2013, doi:<a href=\"https://doi.org/10.1371/journal.pone.0080814\">10.1371/journal.pone.0080814</a>.","apa":"Zagorsky, B., Reiter, J., Chatterjee, K., &#38; Nowak, M.

The verifier is able to recover m from τ and at the same time verify its authenticity. The two most important parameters of such a scheme are its security and overhead |τ| − |m|. A simple argument shows that for any scheme with “n bits security” |τ| − |m| ≥ n, i.e., the overhead is lower bounded by the security parameter n. Currently, the best known constructions in the random oracle model are far from this lower bound requiring an overhead of n + logq h , where q h is the number of queries to the random oracle. In this paper we give a construction which basically matches the n bit lower bound. We propose a simple digital signature scheme with n + o(logq h ) bits overhead, where q h denotes the number of random oracle queries.\r\n\r\nOur construction works in two steps. First, we propose a signature scheme with message recovery having optimal overhead in a new ideal model, the random invertible function model. Second, we show that a four-round Feistel network with random oracles as round functions is tightly “public-indifferentiable” from a random invertible function. At the core of our indifferentiability proof is an almost tight upper bound for the expected number of edges of the densest “small” subgraph of a random Cayley graph, which may be of independent interest.\r\n","lang":"eng"}],"doi":"10.1007/978-3-642-40041-4_31","intvolume":"      8042","page":"571 - 588","_id":"2258","quality_controlled":"1","department":[{"_id":"KrPi"}],"citation":{"ieee":"E.

The LWR problem was shown to be as hard as LWE for a setting of parameters where the modulus and modulus-to-error ratio are super-polynomial. In this work we resolve the main open problem and give a new reduction that works for a larger range of parameters, allowing for a polynomial modulus and modulus-to-error ratio. In particular, a smaller modulus gives us greater efficiency, and a smaller modulus-to-error ratio gives us greater security, which now follows from the worst-case hardness of GapSVP with polynomial (rather than super-polynomial) approximation factors.\r\n\r\nAs a tool in the reduction, we show that there is a “lossy mode” for the LWR problem, in which LWR samples only reveal partial information about the secret. This property gives us several interesting new applications, including a proof that LWR remains secure with weakly random secrets of sufficient min-entropy, and very simple constructions of deterministic encryption, lossy trapdoor functions and reusable extractors.\r\n\r\nOur approach is inspired by a technique of Goldwasser et al. from ICS ’10, which implicitly showed the existence of a “lossy mode” for LWE. By refining this technique, we also improve on the parameters of that work to only requiring a polynomial (instead of super-polynomial) modulus and modulus-to-error ratio.\r\n","lang":"eng"}],"volume":8042,"file_date_updated":"2020-07-14T12:45:35Z","issue":"1","ec_funded":1,"year":"2013","language":[{"iso":"eng"}],"day":"01","title":"Learning with rounding, revisited: New reduction properties and applications","pubrep_id":"684","status":"public","type":"conference","citation":{"ieee":"J.

Here, we demonstrate that neural stem cells (NSCs) and intermediate neural progenitor cells (NPCs) employ a zinc-finger transcription factor specificity protein 2 (Sp2) as a cell cycle regulator in two temporally and spatially distinct progenitor domains. Differential conditional deletion of Sp2 in early embryonic cerebral cortical progenitors, and perinatal olfactory bulb progenitors disrupted transitions through G1, G2 and M phases, whereas DNA synthesis appeared intact. Cell-autonomous function of Sp2 was identified by deletion of Sp2 using mosaic analysis with double markers, which clearly established that conditional Sp2-null NSCs and NPCs are M phase arrested in vivo. Importantly, conditional deletion of Sp2 led to a decline in the generation of NPCs and neurons in the developing and postnatal brains. Our findings implicate Sp2-dependent mechanisms as novel regulators of cell cycle progression, the absence of which disrupts neurogenesis in the embryonic and postnatal brain.","lang":"eng"}],"date_published":"2013-02-01T00:00:00Z","author":[{"last_name":"Liang","first_name":"Huixuan","full_name":"Liang, Huixuan"},{"last_name":"Xiao","first_name":"Guanxi","full_name":"Xiao, Guanxi"},{"full_name":"Yin, Haifeng","first_name":"Haifeng","last_name":"Yin"},{"orcid":"0000-0003-2279-1061","last_name":"Hippenmeyer","first_name":"Simon","id":"37B36620-F248-11E8-B48F-1D18A9856A87","full_name":"Hippenmeyer, Simon"},{"full_name":"Horowitz, Jonathan","first_name":"Jonathan","last_name":"Horowitz"},{"full_name":"Ghashghaei, Troy","first_name":"Troy","last_name":"Ghashghaei"}],"issue":"3","department":[{"_id":"SiHi"}],"quality_controlled":"1","_id":"2264","page":"552 - 561","intvolume":"       140","doi":"10.1242/dev.085621","external_id":{"pmid":["23293287"]},"status":"public","type":"journal_article","title":"Neural development is dependent on the function of specificity protein 2 in cell cycle progression","article_processing_charge":"No","citation":{"ieee":"H.

The agents in such games are vertices in a graph, and the value of a coalition is the sum of the weights of the edges present between coalition members. The optimal coalition structure is a partition of the agents to coalitions, that maximizes the sum of utilities obtained by the coalitions. We  show  that  finding  the  optimal  coalition  structure  is  not only hard for general graphs,  but is also intractable for restricted families such as planar graphs which are amenable for many other combinatorial problems.
