A loopy view of telomere evolution
About a decade ago, I proposed that t-loops, the lariat structures adopted by many eukaryotic telomeres, could explain how the transition from circular to linear chromosomes was successfully negotiated by early eukaryotes. Here I reconsider this loopy hypothesis in the context of the idea that eukaryotes evolved through a period of genome invasion by Group II introns.
متن کاملLoopy Logic
In this paper we describe a new logic-based stochastic modeling language. It is an extension of the Bayesian logic programming approach of Kersting and De Raedt [1]. We specialize the Kirsting and De Raedt formalism by suggesting that product distributions are an effective combining rule for Horn clause heads. We use a refinement of Pearl’s loopy belief propagation [2] for the inference algorit...
متن کاملLoopy SAM
Smoothing approaches to the Simultaneous Localization and Mapping (SLAM) problem in robotics are superior to the more common filtering approaches in being exact, better equipped to deal with non-linearities, and computing the entire robot trajectory. However, while filtering algorithms that perform map updates in constant time exist, no analogous smoothing method is available. We aim to rectify...
متن کاملQuantifying Loopy Network Architectures
Biology presents many examples of planar distribution and structural networks having dense sets of closed loops. An archetype of this form of network organization is the vasculature of dicotyledonous leaves, which showcases a hierarchically-nested architecture containing closed loops at many different levels. Although a number of approaches have been proposed to measure aspects of the structure...
متن کاملHybrid Loopy Belief Propagation
We propose an algorithm called Hybrid Loopy Belief Propagation (HLBP), which extends the Loopy Belief Propagation (LBP) (Murphy et al., 1999) and Nonparametric Belief Propagation (NBP) (Sudderth et al., 2003) algorithms to deal with general hybrid Bayesian networks. The main idea is to represent the LBP messages with mixture of Gaussians and formulate their calculation as Monte Carlo integratio...
