[{"oa_version":"Submitted Version","abstract":[{"text":"The process of gastrulation is highly conserved across vertebrates on both the genetic and morphological levels, despite great variety in embryonic shape and speed of development. This mechanism spatially separates the germ layers and establishes the organizational foundation for future development. Mesodermal identity is specified in a superficial layer of cells, the epiblast, where cells maintain an epithelioid morphology. These cells involute to join the deeper hypoblast layer where they adopt a migratory, mesenchymal morphology. Expression of a cascade of related transcription factors orchestrates the parallel genetic transition from primitive to mature mesoderm. Although the early and late stages of this process are increasingly well understood, the transition between them has remained largely mysterious. We present here the first high resolution in vivo observations of the blebby transitional morphology of involuting mesodermal cells in a vertebrate embryo. We further demonstrate that the zebrafish spadetail mutation creates a reversible block in the maturation program, stalling cells in the transition state. This mutation creates an ideal system for dissecting the specific properties of cells undergoing the morphological transition of maturing mesoderm, as we demonstrate with a direct measurement of cell–cell adhesion.","lang":"eng"}],"publication_status":"published","publisher":"Elsevier","citation":{"mla":"Row, Richard, et al. “Completion of the Epithelial to Mesenchymal Transition in Zebrafish Mesoderm Requires Spadetail.” <i>Developmental Biology</i>, vol. 354, no. 1, Elsevier, 2011, pp. 102–10, doi:<a href=\"https://doi.org/10.1016/j.ydbio.2011.03.025\">10.1016/j.ydbio.2011.03.025</a>.","ieee":"R.

Close to the trap center, this field is typically approximated as linear in the displacement of the trapped microsphere. However, applications demanding high forces at low laser intensities can probe the light-microsphere interaction beyond the linear regime. Here, we measured the full nonlinear force and displacement response of an optical trap in two dimensions using a dual-beam optical trap setup with back-focal-plane photodetection. We observed a substantial stiffening of the trap beyond the linear regime that depends on microsphere size, in agreement with Mie theory calculations. Surprisingly, we found that the linear detection range for forces exceeds the one for displacement by far. Our approach allows for a complete calibration of an optical trap.","lang":"eng"}],"language":[{"iso":"eng"}],"article_processing_charge":"No","department":[{"_id":"CaHe"}],"scopus_import":"1","oa":1,"isi":1,"ddc":["570"],"publist_id":"3234","issue":"7","month":"03","fulldoi":"https://doi.org/10.1364/OL.36.001260","date_updated":"2026-07-29T10:07:18Z","publication":"Optics Letters","date_created":"2018-12-11T12:02:58Z","title":"Measuring the complete force field of an optical trap","main_file_link":[{"url":"https://www.osapublishing.org/ol/abstract.cfm?uri=ol-36-7-1260","open_access":"1"}],"external_id":{"isi":["000289251000080"]},"type":"journal_article","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"1403"}]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"first_name":"Marcus","last_name":"Jahnel","full_name":"Jahnel, Marcus"},{"last_name":"Behrndt","first_name":"Martin","full_name":"Behrndt, Martin","id":"3ECECA3A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Jannasch, Anita","first_name":"Anita","last_name":"Jannasch"},{"full_name":"Schaeffer, Erik","first_name":"Erik","last_name":"Schaeffer"},{"last_name":"Grill","first_name":"Stephan","full_name":"Grill, Stephan"}],"day":"30","page":"1260 - 1262"},{"status":"public","year":"2011","_id":"3393","date_published":"2011-09-01T00:00:00Z","doi":"10.1086/661246","quality_controlled":"1","volume":178,"abstract":[{"lang":"eng","text":"Unlike unconditionally advantageous “Fisherian” variants that tend to spread throughout a species range once introduced anywhere, “bistable” variants, such as chromosome translocations, have two alternative stable frequencies, absence and (near) fixation. Analogous to populations with Allee effects, bistable variants tend to increase locally only once they become sufficiently common, and their spread depends on their rate of increase averaged over all frequencies. Several proposed manipulations of insect populations, such as using Wolbachia or “engineered underdominance” to suppress vector-borne diseases, produce bistable rather than Fisherian dynamics. We synthesize and extend theoretical analyses concerning three features of their spatial behavior: rate of spread, conditions to initiate spread from a localized introduction, and wave stopping caused by variation in population densities or dispersal rates. Unlike Fisherian variants, bistable variants tend to spread spatially only for particular parameter combinations and initial conditions. Wave initiation requires introduction over an extended region, while subsequent spatial spread is slower than for Fisherian waves and can easily be halted by local spatial inhomogeneities. We present several new results, including robust sufficient conditions to initiate (and stop) spread, using a one-parameter cubic approximation applicable to several models. The results have both basic and applied implications."}],"oa_version":"Submitted Version","citation":{"short":"N.H. Barton, M.

This requires us to track only four macroscopic variables, instead of the distribution of all the allele frequencies that influence the trait. These macroscopic variables are the expectations of: the trait mean and its square, the genetic variance, and of a measure of heterozygosity, and are derived from a generating function that is in turn derived by maximizing an entropy measure. These four macroscopics are enough to accurately describe the dynamics of the trait mean and of its genetic variance (and in principle of any other quantity). Unlike previous approaches that were based on an infinite series of moments or cumulants, which had to be truncated arbitrarily, our calculations provide a well-defined approximation procedure. We apply the framework to abrupt and gradual changes in the optimum, as well as to changes in the strength of stabilizing selection. Our approximations are surprisingly accurate, even for systems with as few as five loci. We find that when the effects of drift are included, the expected genetic variance is hardly altered by directional selection, even though it fluctuates in any particular instance. We also find hysteresis, showing that even after averaging over the microscopic variables, the macroscopic trajectories retain a memory of the underlying genetic states.","lang":"eng"}],"corr_author":"1"},{"isi":1,"language":[{"iso":"eng"}],"article_processing_charge":"No","oa":1,"department":[{"_id":"ToHe"}],"scopus_import":"1","publisher":"Springer Nature","publication_status":"published","publication_identifier":{"issn":["0302-9743"],"eisbn":["9783642175114"],"isbn":["9783642175107"],"eissn":["1611-3349"]},"conference":{"end_date":"2010-05-01","location":"Dakar, Senegal","name":"LPAR: Logic for Programming, Artificial Intelligence and Reasoning","start_date":"2010-04-25"},"citation":{"apa":"Blanc, R., Henzinger, T.

Methods and programs abound that use the gene alignment in different ways to reconstruct the species tree. In particular, different methods combine the original data at different points along the way from the underlying sequences to the final tree. Accordingly, they are classified into superalignment, supertree and medium-level approaches. Here, we present a simulation study to compare different methods from each of these three approaches.\r\n\r\nResults: We observe that superalignment methods usually outperform the other approaches over a wide range of parameters including sparse data and gene-specific evolutionary parameters. In the presence of high incongruency among gene trees, however, other combination methods show better performance than the superalignment approach. Surprisingly, some supertree and medium-level methods exhibit, on average, worse results than a single gene phylogeny with complete taxon information.\r\n\r\nConclusions: For some methods, using the reconstructed gene tree as an estimation of the species tree is superior to the combination of incomplete information. Superalignment usually performs best since it is less susceptible to stochastic error. Supertree methods can outperform superalignment in the presence of gene-tree conflict.","lang":"eng"}],"file":[{"date_created":"2018-12-12T10:09:16Z","content_type":"application/pdf","checksum":"e2497285388bc4da629bafb46662eb43","file_id":"4739","relation":"main_file","access_level":"open_access","creator":"system","date_updated":"2020-07-14T12:45:40Z","file_size":723929,"file_name":"IST-2018-939-v1+1_2010_Kupczok_Accuracy_of.pdf"}],"external_id":{"isi":["000286183400001"]},"type":"journal_article","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","day":"06","author":[{"id":"2BB22BC2-F248-11E8-B48F-1D18A9856A87","full_name":"Kupczok, Anne","last_name":"Kupczok","first_name":"Anne"},{"last_name":"Schmidt","first_name":"Heiko","full_name":"Schmidt, Heiko"},{"first_name":"Arndt","last_name":"Von Haeseler","full_name":"Von Haeseler, Arndt"}],"issue":"1","month":"12","fulldoi":"https://doi.org/10.1186/1748-7188-5-37","date_updated":"2025-09-30T09:48:29Z","file_date_updated":"2020-07-14T12:45:40Z","date_created":"2018-12-11T11:57:30Z","publication":"Algorithms for Molecular Biology","has_accepted_license":"1","title":"Accuracy of phylogeny reconstruction methods combining overlapping gene data sets"},{"article_processing_charge":"No","scopus_import":"1","department":[{"_id":"XiFe"}],"language":[{"iso":"eng"}],"pmid":1,"date_published":"2010-07-15T00:00:00Z","_id":"12199","year":"2010","status":"public","quality_controlled":"1","volume":137,"acknowledgement":"We thank the following for providing mutant lines and reagents: Hong Ma, De Ye, Sacco De Vries, and Rod Scott for providing the pA9::Barnase lines and information on A9 expression patterns.

Within each microsporangium, developing microsporocytes are surrounded by concentric monolayers of tapetal, middle layer and endothecial cells. How this intricate array of tissues, each containing relatively few cells, is established in an organ possessing no formal meristems is poorly understood. We describe here the pivotal role of the LRR receptor kinase EXCESS MICROSPOROCYTES 1 (EMS1) in forming the monolayer of tapetal nurse cells in Arabidopsis. Unusually for plants, tapetal cells are specified very early in development, and are subsequently stimulated to proliferate by a receptor-like kinase (RLK) complex that includes EMS1. Mutations in members of this EMS1 signalling complex and its putative ligand result in male-sterile plants in which tapetal initials fail to proliferate. Surprisingly, these cells continue to develop, isolated at the locular periphery. Mutant and wild-type microsporangia expand at similar rates and the ‘tapetal’ space at the periphery of mutant locules becomes occupied by microsporocytes. However, induction of late expression of EMS1 in the few tapetal initials in ems1 plants results in their proliferation to generate a functional tapetum, and this proliferation suppresses microsporocyte number. Our experiments also show that integrity of the tapetal monolayer is crucial for the maintenance of the polarity of divisions within it. This unexpected autonomy of the tapetal ‘lineage’ is discussed in the context of tissue development in complex plant organs, where constancy in size, shape and cell number is crucial."}],"publication_identifier":{"issn":["1477-9129","0950-1991"]},"publication_status":"published","publisher":"The Company of Biologists","intvolume":"       137","citation":{"apa":"Feng, X., &#38; Dickinson, H.

Mutant studies in the model plant Arabidopsis thaliana are leading to an increasingly accurate picture of (i) the cell lineages culminating in the different cell types present in the microsporangium (the microsporocytes, the tapetum, and the middle and endothecial layers), and (ii) some of the genes responsible for specifying their fates. However, the processes that confer polarity on the developing anther and position the microsporangia within it remain unclear. Certainly, data from a range of experimental strategies suggest that hormones play a central role in establishing polarity and the patterning of the anther initial, and may be responsible for locating the microsporangia. But the fact that microsporangia were originally positioned externally suggests that their development is likely to be autonomous, perhaps with the reproductive cells generating signals controlling the growth and division of the investing anther epidermis. These possibilities are discussed in the context of the expression of genes which initiate and maintain male and female reproductive development, and in the perspective of our current views of anther evolution."}],"publication_status":"published","publisher":"Portland Press Ltd.","publication_identifier":{"issn":["0300-5127","1470-8752"]},"citation":{"short":"X.

We handle full mtl and include all future operators. Our construction is based on separation of the continuous time monitoring of the input sequence and discrete predictions regarding the future. The separation of the continuous from the discrete allows us to determinize our automata in an exponential construction that does not increase the number of clocks. This leads to a doubly exponential construction from mtl to deterministic timed automata, compared with triply exponential using existing approaches. We offer an alternative to the existing approach to linear real-time model checking, which has never been implemented. It further offers a unified framework for model checking, runtime monitoring, and synthesis, in an approach that can reuse tools, implementations, and insights from the discrete setting."}],"oa_version":"Submitted Version","language":[{"iso":"eng"}],"pubrep_id":"49","oa":1,"scopus_import":1,"department":[{"_id":"ToHe"}],"project":[{"_id":"25EFB36C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"COMponent-Based Embedded Systems design Techniques","grant_number":"215543"},{"_id":"25F1337C-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Design for Embedded Systems","grant_number":"214373"}],"publist_id":"1090","ddc":["004"],"month":"09","file_date_updated":"2020-07-14T12:46:27Z","date_updated":"2024-10-09T20:54:01Z","fulldoi":"https://doi.org/10.1007/978-3-642-15297-9_13","date_created":"2018-12-11T12:08:30Z","title":"From MTL to deterministic timed automata","editor":[{"last_name":"Henzinger","first_name":"Thomas A.","full_name":"Henzinger, Thomas A."},{"full_name":"Chatterjee, Krishnendu","first_name":"Krishnendu","last_name":"Chatterjee"}],"has_accepted_license":"1","file":[{"file_size":249789,"date_updated":"2020-07-14T12:46:27Z","file_name":"IST-2012-49-v1+1_From_MTL_to_deterministic_timed_automata.pdf","creator":"system","relation":"main_file","access_level":"open_access","file_id":"5028","checksum":"b0ca5f5fbe8a3d20ccbc6f51a344a459","content_type":"application/pdf","date_created":"2018-12-12T10:13:43Z"}],"user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","type":"conference","page":"152 - 167","day":"08","author":[{"first_name":"Dejan","last_name":"Nickovic","id":"41BCEE5C-F248-11E8-B48F-1D18A9856A87","full_name":"Nickovic, Dejan"},{"last_name":"Piterman","first_name":"Nir","full_name":"Piterman, Nir"}]},{"publist_id":"1081","oa":1,"department":[{"_id":"ToHe"}],"scopus_import":1,"language":[{"iso":"eng"}],"abstract":[{"text":"Techniques such as verification condition generation, predicate abstraction, and expressive type systems reduce software verification to proving formulas in expressive logics. Programs and their specifications often make use of data structures such as sets, multisets, algebraic data types, or graphs. Consequently, formulas generated from verification also involve such data structures. To automate the proofs of such formulas we propose a logic (a “calculus”) of such data structures. We build the calculus by starting from decidable logics of individual data structures, and connecting them through functions and sets, in ways that go beyond the frameworks such as Nelson-Oppen. The result are new decidable logics that can simultaneously specify properties of different kinds of data structures and overcome the limitations of the individual logics. Several of our decidable logics include abstraction functions that map a data structure into its more abstract view (a tree into a multiset, a multiset into a set), into a numerical quantity (the size or the height), or into the truth value of a candidate data structure invariant (sortedness, or the heap property). For algebraic data types, we identify an asymptotic many-to-one condition on the abstraction function that guarantees the existence of a decision procedure. In addition to the combination based on abstraction functions, we can combine multiple data structure theories if they all reduce to the same data structure logic. As an instance of this approach, we describe a decidable logic whose formulas are propositional combinations of formulas in: weak monadic second-order logic of two successors, two-variable logic with counting, multiset algebra with Presburger arithmetic, the Bernays-Schönfinkel-Ramsey class of first-order logic, and the logic of algebraic data types with the set content function. The subformulas in this combination can share common variables that refer to sets of objects along with the common set algebra operations. Such sound and complete combination is possible because the relations on sets definable in the component logics are all expressible in Boolean Algebra with Presburger Arithmetic. Presburger arithmetic and its new extensions play an important role in our decidability results. In several cases, when we combine logics that belong to NP, we can prove the satisfiability for the combined logic is still in NP.","lang":"eng"}],"oa_version":"Submitted Version","conference":{"location":"Madrid, Spain","end_date":"2010-01-19","start_date":"2010-01-17","name":"VMCAI: Verification, Model Checking and Abstract Interpretation"},"citation":{"apa":"Kuncak, V., Piskac, R., Suter, P., &#38; Wies, T.

We claim that, in order to realize the full potential of cloud computing, the user must be presented with a pricing model that offers flexibility at the requirements level, such as a choice between different degrees of execution speed and the cloud provider must be presented with a programming model that offers flexibility at the execution level, such as a choice between different scheduling policies. In such a flexible framework, with each job, the user purchases a virtual computer with the desired speed and cost characteristics, and the cloud provider can optimize the utilization of resources across a stream of jobs from different users. We designed a flexible framework to test our hypothesis, which is called FlexPRICE (Flexible Provisioning of Resources in a Cloud Environment) and works as follows. A user presents a job to the cloud. The cloud finds different schedules to execute the job and presents a set of quotes to the user in terms of price and duration for the execution. The user then chooses a particular quote and the cloud is obliged to execute the job according to the chosen quote. FlexPRICE thus hides the complexity of the actual scheduling decisions from the user, but still provides enough flexibility to meet the users actual demands. We implemented FlexPRICE in a simulator called PRICES that allows us to experiment with our framework. We observe that FlexPRICE provides a wide range of execution options-from fast and expensive to slow and cheap-- for the whole spectrum of data-intensive and computation-intensive jobs. We also observe that the set of quotes computed by FlexPRICE do not vary as the number of simultaneous jobs increases."}],"corr_author":"1","oa_version":"Submitted Version","citation":{"ama":"Henzinger TA, Tomar A, Singh V, Wies T, Zufferey D.

Inspired by classical work on databases, formal definitions of the semantics of TM executions have been proposed. Many of these definitions assumed that accesses to shared data are solely performed through transactions. In practice, due to legacy code and concurrency libraries, transactions in a TM have to share data with non-transactional operations. The semantics of such interaction, while widely discussed by practitioners, lacks a clear formal specification. Those interactions can vary, sometimes in subtle ways, between TM implementations and underlying memory models. We propose a correctness condition for TMs, parametrized opacity, to formally capture the now folklore notion of strong atomicity by stipulating the two following intuitive requirements: first, every transaction appears as if it is executed instantaneously with respect to other transactions and non-transactional operations, and second, non-transactional operations conform to the given underlying memory model. We investigate the inherent cost of implementing parametrized opacity. We first prove that parametrized opacity requires either instrumenting non-transactional operations (for most memory models) or writing to memory by transactions using potentially expensive read-modify-write instructions (such as compare-and-swap). Then, we show that for a class of practical relaxed memory models, parametrized opacity can indeed be implemented with constant-time instrumentation of non-transactional writes and no instrumentation of non-transactional reads. We show that, in practice, parametrizing the notion of correctness allows developing more efficient TM implementations.","lang":"eng"}],"language":[{"iso":"eng"}],"pubrep_id":"46","department":[{"_id":"ToHe"}],"scopus_import":"1","oa":1,"publist_id":"1076","ddc":["005"],"month":"06","date_updated":"2024-10-21T06:03:05Z","fulldoi":"https://doi.org/10.1145/1810479.1810529","file_date_updated":"2020-07-14T12:46:28Z","date_created":"2018-12-11T12:08:34Z","has_accepted_license":"1","title":"Transactions in the jungle","file":[{"date_created":"2018-12-12T10:14:28Z","file_id":"5080","checksum":"f2ad6c00a6304da34bf21bcdcfd36c4b","content_type":"application/pdf","creator":"system","access_level":"open_access","relation":"main_file","file_name":"IST-2012-46-v1+1_Transactions_in_the_jungle.pdf","date_updated":"2020-07-14T12:46:28Z","file_size":246409}],"type":"conference","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Guerraoui, Rachid","first_name":"Rachid","last_name":"Guerraoui"},{"last_name":"Henzinger","first_name":"Thomas A","orcid":"0000−0002−2985−7724","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Kapalka","first_name":"Michal","full_name":"Kapalka, Michal"},{"first_name":"Vasu","last_name":"Singh","id":"4DAE2708-F248-11E8-B48F-1D18A9856A87","full_name":"Singh, Vasu"}],"day":"13","page":"263 - 272"}]
