In sorting the motor behavior by the clockwise bias, we find that the distributions of the clockwise (CW) and counterclockwise (CCW) intervals are either exponential or nonexponential with long tails. At low bias, CW intervals are exponentially distributed and CCW intervals exhibit long tails. At intermediate CW bias (0.5) both CW and CCW intervals are mainly exponentially distributed. A simple model suggests that these two distinct switching behaviors are governed by the presence of signaling noise within the chemotaxis network. Low noise yields exponentially distributed intervals, whereas large noise yields nonexponential behavior with long tails. These drastically different motor statistics may play a role in optimizing bacterial behavior for a wide range of environmental conditions."}],"pmid":1,"intvolume":"       101","article_processing_charge":"No","publisher":"Elsevier","issue":"10","publication":"Biophysical Journal","day":"16","page":"2336-2340","volume":101,"type":"journal_article","quality_controlled":"1","year":"2011","date_created":"2019-05-28T11:54:29Z","citation":{"ama":"Park H, Oikonomou P, Guet CC, Cluzel P.

To faithfully capture this combinatorial process in a math- ematical model is an important challenge in systems biology. Exploiting the limited context on which most binding and modification events are conditioned, attempts have been made to reduce the com- binatorial complexity by quotienting the reachable set of molecular species, into species aggregates while preserving the deterministic semantics of the thermodynamic limit. Recently we proposed a quotienting that also preserves the stochastic semantics and that is complete in the sense that the semantics of individual species can be recovered from the aggregate semantics. In this paper we prove that this quotienting yields a sufficient condition for weak lumpability and that it gives rise to a backward Markov bisimulation between the original and aggregated transition system. We illustrate the framework on a case study of the EGF/insulin receptor crosstalk."}],"intvolume":"        40","status":"public","arxiv":1,"publication_status":"published","file":[{"access_level":"open_access","file_id":"5904","checksum":"eaaba991a86fff37606b0eb5196878e8","file_size":907155,"date_updated":"2020-07-14T12:46:14Z","creator":"kschuh","file_name":"Lumpability_abstractions_of_rule-based_systems.pdf","date_created":"2019-01-31T12:09:09Z","relation":"main_file","content_type":"application/pdf"}],"type":"conference","volume":40,"day":"30","page":"142-161","publisher":"Open Publishing Association","acknowledgement":"Jérôme Feret’s contribution was partially supported by the ABSTRACTCELL ANR-Chair of Excellence.

SABRE implements fast adaptive uniformization (FAU), a direct numerical approximation algorithm for computing transient solutions of biochemical reaction networks. Biochemical reactions networks represent biological systems studied at a molecular level and these reactions can be modeled as transitions of a Markov chain. SABRE accepts as input the formalism of guarded commands, which it interprets either as continuous-time or as discrete-time Markov chains. Besides operating in a stochastic mode, SABRE may also perform a deterministic analysis by directly computing a mean-field approximation of the system under study. We illustrate the different functionalities of SABRE by means of biological case studies.","lang":"eng"}],"pubrep_id":"63","file":[{"access_level":"open_access","file_id":"4726","file_size":433824,"checksum":"38707b149d2174f01be406e794ffa849","date_updated":"2020-07-14T12:46:17Z","creator":"system","file_name":"IST-2012-63-v1+1_SABRE-A_tool_for_the_stochastic_analysis_of_biochemical_reaction_networks.pdf","date_created":"2018-12-12T10:09:03Z","content_type":"application/pdf","relation":"main_file"}],"publication_status":"published","title":"SABRE: A tool for the stochastic analysis of biochemical reaction networks","file_date_updated":"2020-07-14T12:46:17Z","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","publist_id":"2339","oa":1,"citation":{"ista":"Didier F, Henzinger TA, Mateescu M, Wolf V. 2010.

An appropriate stochastic description is provided by the chemical master equation, which represents a continuous- time Markov chain (CTMC).\r\nStandard Uniformization (SU) is an efficient method for the transient analysis of CTMCs. For systems with very different time scales, such as biochemical reaction networks, SU is computationally expensive. In these cases, a variant of SU, called adaptive uniformization (AU), is known to reduce the large number of iterations needed by SU. The additional difficulty of AU is that it requires the solution of a birth process.\r\nIn this paper we present an on-the-fly variant of AU, where we improve the original algorithm for AU at the cost of a small approximation error.
