We say that the relaxation is totally half-integral if f̂(x) is a polyhedral function with half-integral extreme points x, and this property is preserved after adding an arbitrary combination of constraints of the form x i=x j, x i=1-x j, and x i=γ where γ∈{0,1,1/2} is a constant. A well-known example is the roof duality relaxation for quadratic pseudo-Boolean functions f. We argue that total half-integrality is a natural requirement for generalizations of roof duality to arbitrary pseudo-Boolean functions. Our contributions are as follows. First, we provide a complete characterization of totally half-integral relaxations f̂ by establishing a one-to-one correspondence with bisubmodular functions. Second, we give a new characterization of bisubmodular functions. Finally, we show some relationships between general totally half-integral relaxations and relaxations based on the roof duality. On the conceptual level, our results show that bisubmodular functions provide a natural generalization of the roof duality approach to higher-order terms. This can be viewed as a non-submodular analogue of the fact that submodular functions generalize the s-t minimum cut problem with non-negative weights to higher-order terms.","lang":"eng"}],"type":"journal_article","external_id":{"arxiv":["1005.2305"]},"date_published":"2012-03-01T00:00:00Z","publisher":"Elsevier","month":"03","publist_id":"3397","status":"public","language":[{"iso":"eng"}],"quality_controlled":"1","page":"416 - 426","day":"01","issue":"4-5"},{"abstract":[{"lang":"eng","text":"CA3 pyramidal neurons are important for memory formation and pattern completion in the hippocampal network. It is generally thought that proximal synapses from the mossy fibers activate these neurons most efficiently, whereas distal inputs from the perforant path have a weaker modulatory influence. We used confocally targeted patch-clamp recording from dendrites and axons to map the activation of rat CA3 pyramidal neurons at the subcellular level. Our results reveal two distinct dendritic domains. In the proximal domain, action potentials initiated in the axon backpropagate actively with large amplitude and fast time course. In the distal domain, Na+ channel–mediated dendritic spikes are efficiently initiated by waveforms mimicking synaptic events. CA3 pyramidal neuron dendrites showed a high Na+-to-K+ conductance density ratio, providing ideal conditions for active backpropagation and dendritic spike initiation. Dendritic spikes may enhance the computational power of CA3 pyramidal neurons in the hippocampal network."}],"year":"2012","citation":{"ama":"Kim S, Guzmán J, Hu H, Jonas PM.

Here we study the evolution of bids in biological auctions. For each auction, n individuals are drawn at random from a population of size N. Each individual makes a bid which entails a cost. The winner obtains a benefit of a certain value. Costs and benefits are translated into reproductive success (fitness). Therefore, successful bidding strategies spread in the population. We compare two types of auctions. In “biological all-pay auctions”, the costs are the bid for every participating individual. In “biological second price all-pay auctions”, the cost for everyone other than the winner is the bid, but the cost for the winner is the second highest bid. Second price all-pay auctions are generalizations of the “war of attrition” introduced by Maynard Smith. We study evolutionary dynamics in both types of auctions. We calculate pairwise invasion plots and evolutionarily stable distributions over the continuous strategy space. We find that the average bid in second price all-pay auctions is higher than in all-pay auctions, but the average cost for the winner is similar in both auctions. In both cases, the average bid is a declining function of the number of participants, n. The more individuals participate in an auction the smaller is the chance of winning, and thus expensive bids must be avoided.\r\n","lang":"eng"}],"year":"2012","citation":{"mla":"Chatterjee, Krishnendu, et al. “Evolutionary Dynamics of Biological Auctions.” <i>Theoretical Population Biology</i>, vol. 81, no. 1, Academic Press, 2012, pp. 69–80, doi:<a href=\"https://doi.org/10.1016/j.tpb.2011.11.003\">10.1016/j.tpb.2011.11.003</a>.","short":"K.

But the expression of transcription factor proteins is itself regulated, and many transcription factors regulate their own expression in addition to responding to other input signals. Here we analyze the simplest of such self-regulatory circuits, asking how parameters can be chosen to optimize information transmission from inputs to outputs in the steady state. Some nonzero level of self-regulation is almost always optimal, with self-activation dominant when transcription factor concentrations are low and self-repression dominant when concentrations are high. In steady state the optimal self-activation is never strong enough to induce bistability, although there is a limit in which the optimal parameters are very close to the critical point.","lang":"eng"}],"date_published":"2012-04-01T00:00:00Z","type":"journal_article","publisher":"American Institute of Physics","month":"04","status":"public","publist_id":"3386","language":[{"iso":"eng"}],"quality_controlled":"1","day":"01","issue":"4"},{"type":"conference","date_published":"2012-01-12T00:00:00Z","author":[{"full_name":"Ion, Adrian","id":"29F89302-F248-11E8-B48F-1D18A9856A87","last_name":"Ion","first_name":"Adrian"},{"full_name":"Carreira, Joao","first_name":"Joao","last_name":"Carreira"},{"full_name":"Sminchisescu, Cristian","first_name":"Cristian","last_name":"Sminchisescu"}],"publisher":"IEEE","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"HeEd"}],"month":"01","date_updated":"2021-01-12T07:42:15Z","publist_id":"3382","status":"public","language":[{"iso":"eng"}],"quality_controlled":"1","publication_status":"published","title":"Image segmentation by figure-ground composition into maximal cliques","oa_version":"None","doi":"10.1109/ICCV.2011.6126486","day":"12","conference":{"start_date":"2011-11-06","end_date":"2011-11-13","location":"Barcelona, Spain","name":"ICCV: International Conference on Computer Vision"},"date_created":"2018-12-11T12:02:21Z","_id":"3265","citation":{"ama":"Ion A, Carreira J, Sminchisescu C.

Potential functions over cliques combine unary, Gestalt-based figure qualities, and pairwise compatibilities among spatially neighboring segments, constrained by T-junctions and the boundary interface statistics of real scenes. Learning the model parameters is based on maximum likelihood, alternating between sampling image tilings and optimizing their potential function parameters.

By now it is clear that clues to the understanding of this crucial transition in the evolution of life can arise in a fourth pathway besides the three possibilities in the quest for simplicity outlined by Bonner in his classical book. In other words, solar system exploration seems to be one way in the long-term to elucidate the simplicity of evolutionary development. We place these ideas in the context of different inheritance systems, namely the genotypic and phenotypic replicators with limited or unlimited heredity, and ask which of these can support multicellular development, and to which degree of complexity. However, the quest for evidence on the evolution of biotas from planets around other stars does not seem to be feasible with present technology with direct visualization of living organisms on exoplanets. But this may be attempted on the Galilean moons of Jupiter where there is a possibility of detecting reliable biomarkers in the next decade with the Europa Jupiter System Mission, in view of recent progress by landing micropenetrators on planetary, or satellite surfaces. Mars is a second possibility in the inner Solar System, in spite of the multiple difficulties faced by the fleet of past, present and future missions.

The learning parities with noise problem (LPN) is the special case where the elements of the vectors are bits. In recent years, the LWE and LPN problems have found many applications in cryptography. In this paper we introduce a (seemingly) much stronger adaptive assumption, called &quot;subspace LWE&quot; (SLWE), where the adversary can learn the inner product of the secret and random vectors after they were projected into an adaptively and adversarially chosen subspace. We prove that, surprisingly, the SLWE problem mapping into subspaces of dimension d is almost as hard as LWE using secrets of length d (the other direction is trivial.) This result immediately implies that several existing cryptosystems whose security is based on the hardness of the LWE/LPN problems are provably secure in a much stronger sense than anticipated. As an illustrative example we show that the standard way of using LPN for symmetric CPA secure encryption is even secure against a very powerful class of related key attacks.

In this work we propose a wide variety of other approaches to building efficient MACs, without going through a PRF first. In particular, unlike deterministic PRF-based MACs, where each message has a unique valid tag, we give a number of probabilistic MAC constructions from various other primitives/assumptions. Our main results are summarized as follows: We show several new probabilistic MAC constructions from a variety of general assumptions, including CCA-secure encryption, Hash Proof Systems and key-homomorphic weak PRFs. By instantiating these frameworks under concrete number theoretic assumptions, we get several schemes which are more efficient than just using a state-of-the-art PRF instantiation under the corresponding assumption. For probabilistic MACs, unlike deterministic ones, unforgeability against a chosen message attack (uf-cma ) alone does not imply security if the adversary can additionally make verification queries (uf-cmva ). We give an efficient generic transformation from any uf-cma secure MAC which is &quot;message-hiding&quot; into a uf-cmva secure MAC. This resolves the main open problem of Kiltz et al. from Eurocrypt'11; By using our transformation on their constructions, we get the first efficient MACs from the LPN assumption. While all our new MAC constructions immediately give efficient actively secure, two-round symmetric-key identification schemes, we also show a very simple, three-round actively secure identification protocol from any weak PRF. In particular, the resulting protocol is much more efficient than the trivial approach of building a regular PRF from a weak PRF. © 2012 International Association for Cryptologic Research.","lang":"eng"}],"title":"Message authentication, revisited","publication_status":"published","file_date_updated":"2020-07-14T12:46:06Z","oa_version":"Submitted Version","doi":"10.1007/978-3-642-29011-4_22","acknowledgement":"Supported by the European Research Council under the European Union’s Seventh Framework Programme (FP7/2007-2013) / ERC Starting Grant (259668-PSPC)","department":[{"_id":"KrPi"}],"ec_funded":1,"date_updated":"2021-01-12T07:42:22Z","intvolume":"      7237","oa":1,"volume":7237,"author":[{"first_name":"Yevgeniy","last_name":"Dodis","full_name":"Dodis, Yevgeniy"},{"first_name":"Krzysztof Z","last_name":"Pietrzak","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z"},{"full_name":"Kiltz, Eike","last_name":"Kiltz","first_name":"Eike"},{"full_name":"Wichs, Daniel","last_name":"Wichs","first_name":"Daniel"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","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)"},"project":[{"_id":"258C570E-B435-11E9-9278-68D0E5697425","name":"Provable Security for Physical Cryptography","grant_number":"259668","call_identifier":"FP7"}],"has_accepted_license":"1","pubrep_id":"686","quality_controlled":"1","page":"355 - 374","day":"10","month":"03","status":"public","publist_id":"3364","language":[{"iso":"eng"}],"ddc":["000","004"],"alternative_title":["LNCS"],"date_published":"2012-03-10T00:00:00Z","type":"conference","publisher":"Springer"},{"pmid":1,"publisher":"ASM","type":"journal_article","date_published":"2012-01-01T00:00:00Z","external_id":{"pmid":["22031940"]},"language":[{"iso":"eng"}],"month":"01","publist_id":"3356","status":"public","page":"172 - 184","day":"01","quality_controlled":"1","issue":"1","author":[{"full_name":"Pereira, Anna","first_name":"Anna","last_name":"Pereira"},{"first_name":"Flávia","last_name":"Leite","id":"36705F98-F248-11E8-B48F-1D18A9856A87","full_name":"Leite, Flávia"},{"first_name":"Bruno","last_name":"Brasil","full_name":"Brasil, Bruno"},{"full_name":"Soares Martins, Jamaria","first_name":"Jamaria","last_name":"Soares Martins"},{"first_name":"Alice","last_name":"Torres","full_name":"Torres, Alice"},{"full_name":"Pimenta, Paulo","first_name":"Paulo","last_name":"Pimenta"},{"first_name":"Thais","last_name":"Souto Padrón","full_name":"Souto Padrón, Thais"},{"last_name":"Tranktman","first_name":"Paula","full_name":"Tranktman, Paula"},{"full_name":"Ferreira, Paulo","first_name":"Paulo","last_name":"Ferreira"},{"last_name":"Kroon","first_name":"Erna","full_name":"Kroon, Erna"},{"first_name":"Cláudio","last_name":"Bonjardim","full_name":"Bonjardim, Cláudio"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","volume":86,"oa":1,"intvolume":"        86","department":[{"_id":"JoBo"}],"date_updated":"2021-01-12T07:42:25Z","publication":"Journal of Virology","scopus_import":1,"doi":"10.1128/JVI.05638-11","main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3255887/"}],"acknowledgement":"This work was supported by grants from Fundação de Amparo a Pesquisa do Estado de Minas Gerais (FAPEMIG), the Brazilian Federal Agency for Support and Evaluation of Graduate Education (CAPES), and the National Council for Scientific and Technological Development (CNPq).

Here, we demonstrate that vaccinia virus (VACV) infection leads to activation of the stress-activated protein kinase (SAPK)/extracellular signal-regulated kinase (ERK) 4/7 (MKK4/7)-c-Jun N-terminal protein kinase 1/2 (JNK1/2) pathway; further, the stimulation of this pathway requires postpenetration, prereplicative events in the viral replication cycle. Although the formation of intracellular mature virus (IMV) was not affected in MKK4/7- or JNK1/2-knockout (KO) cells, we did note an accentuated deregulation of microtubule and actin network organization in infected JNK1/2-KO cells. This was followed by deregulated viral trafficking to the periphery and enhanced enveloped particle release. Furthermore, VACV infection induced alterations in the cell contractility and morphology, and cell migration was reduced in the JNK-KO cells. In addition, phosphorylation of proteins implicated with early cell contractility and cell migration, such as microtubule-associated protein 1B and paxillin, respectively, was not detected in the VACV-infected KO cells. In sum, our findings uncover a regulatory role played by the MKK4/7-JNK1/2 pathway in cytoskeleton reorganization during VACV infection.\r\n","lang":"eng"}],"date_created":"2018-12-11T12:02:29Z","_id":"3289"},{"issue":"11","has_accepted_license":"1","pubrep_id":"542","quality_controlled":"1","page":"1436 - 1444","day":"01","month":"08","status":"public","publist_id":"3330","language":[{"iso":"eng"}],"ddc":["000"],"date_published":"2012-08-01T00:00:00Z","type":"journal_article","publisher":"Elsevier","_id":"3310","date_created":"2018-12-11T12:02:36Z","file":[{"date_created":"2018-12-12T10:15:00Z","relation":"main_file","file_size":280280,"date_updated":"2020-07-14T12:46:06Z","file_name":"IST-2016-542-v1+1_2012-J-01-Poinculus.pdf","access_level":"open_access","checksum":"d65f79775b51258a604ca5ec741297cc","content_type":"application/pdf","creator":"system","file_id":"5116"}],"year":"2012","citation":{"short":"P.

For both discounted and mean-payoff two-level games, we show the existence of pure memoryless optimal strategies for both players and an ordered field property. We show that if there is only one player (Markov decision processes), then the values can be computed in polynomial time.

Recent functional analysis indicates that in some fast central synapses, transmitter release is triggered by a small number of Ca2+ channels that are coupled to Ca2+ sensors at the nanometre scale. Molecular analysis suggests that this tight coupling is generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors and various other synaptic proteins. Nanodomain coupling has several functional advantages, as it increases the efficacy, speed and energy efficiency of synaptic transmission.","lang":"eng"}],"year":"2012","citation":{"ama":"Eggermann E, Bucurenciu I, Goswami S, Jonas PM.

We also consider the important special case of turn-based stochastic games where players make moves in turns, rather than concurrently. We study concurrent games with \\omega-regular winning conditions specified as parity objectives. The value for player 1 for a parity objective is the maximal probability with which the player can guarantee the satisfaction of the objective against all strategies of the opponent. We study the problem of continuity and robustness of the value function in concurrent and turn-based stochastic parity gameswith respect to imprecision in the transition probabilities. We present quantitative bounds on the difference of the value function (in terms of the imprecision of the transition probabilities) and show the value continuity for structurally equivalent concurrent games (two games are structurally equivalent if the support of the transition function is same and the probabilities differ). We also show robustness of optimal strategies for structurally equivalent turn-based stochastic parity games. Finally we show that the value continuity property breaks without the structurally equivalent assumption (even for Markov chains) and show that our quantitative bound is asymptotically optimal. Hence our results are tight (the assumption is both necessary and sufficient) and optimal (our quantitative bound is asymptotically optimal)."}],"year":"2012","citation":{"ieee":"K.

HTL is a hierarchical extension of Giotto and, like its predecessor, based on the logical execution time (LET) paradigm of real-time programming. Giotto is compiled into code for a virtual machine, called the EmbeddedMachine (or E machine). If HTL is targeted to the E machine, then the hierarchicalprogram structure needs to be flattened; the flattening makes separatecompilation difficult, and may result in E machinecode of exponential size. In this paper, we propose a generalization of the E machine, which supports a hierarchicalprogram structure at runtime through real-time trigger mechanisms that are arranged in a tree. We present the generalized E machine, and a modular compiler for HTL that generates code of linear size. The compiler may generate code for any part of a given HTL program separately in any order.","lang":"eng"}],"issue":"2","date_created":"2018-12-11T12:05:26Z","_id":"3836","scopus_import":1,"page":"96 - 112","doi":"10.1016/j.scico.2010.06.004","day":"01","title":"Separate compilation of hierarchical real-time programs into linear-bounded embedded machine code","quality_controlled":"1","publication_status":"published","oa_version":"None","language":[{"iso":"eng"}],"intvolume":"        77","department":[{"_id":"ToHe"}],"month":"02","date_updated":"2021-01-12T07:52:32Z","publist_id":"2370","status":"public","publication":"Science of Computer Programming","author":[{"first_name":"Arkadeb","last_name":"Ghosal","full_name":"Ghosal, Arkadeb"},{"full_name":"Iercan, Daniel","last_name":"Iercan","first_name":"Daniel"},{"full_name":"Kirsch, Christoph","last_name":"Kirsch","first_name":"Christoph"},{"first_name":"Thomas A","last_name":"Henzinger","orcid":"0000−0002−2985−7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","full_name":"Henzinger, Thomas A"},{"full_name":"Sangiovanni Vincentelli, Alberto","first_name":"Alberto","last_name":"Sangiovanni Vincentelli"}],"publisher":"Elsevier","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","type":"journal_article","date_published":"2012-02-01T00:00:00Z","volume":77}]
