How optimal is the genetic code?
The genetic code is well-known to be fault tolerant, in the sense that transcription errors in the third codon position frequently do not influence the amino acid expressed, while errors in other codon positions often lead to amino acids having similar chemical properties. Several articles in the recent past ([?, ?, ?] etc.) have studied the question of optimality of the genetic code. In [?] Di...
متن کاملA modified optimal stomatal conductance model under water-stressed condition
Accurate estimation of leaf stomatal conductance (gs) is important in predicting carbon andwater cycles of terrestrial ecosystem. To estimate gs on field-grown soybean and maize underwater-stressed condition accurately, a modified optimal stomatal conductance (OSCM) modelwas established based on the relationship between marginal water cost of carbon gain and soilwater content by introducing a w...
متن کاملTo which extend is the "neural code" a metric ?
Here is proposed a review of the different choices to structure spike trains, using deterministic metrics. Temporal constraints observed in biological or computational spike trains are first taken into account The relation with existing neural codes (rate coding, rank coding, phase coding, ..) is then discussed. To which extend the “neural code” contained in spike trains is related to a metric ...
متن کاملSimulation of a Model-based Optimal Controller for Heating Systems under Realistic Hypotheses
An optimal controller for auxiliary heating of passive solar buildings and commercial buildings with high internal gains is tested in simulation. Some of the most restrictive simplifications that were used in previous studies of that controller (Kummert et al., 2001) are lifted: the controller is applied to a multizone building, and a detailed model is used for the HVAC system. The model-based ...
متن کاملEarly fixation of an optimal genetic code.
The evolutionary forces that produced the canonical genetic code before the last universal ancestor remain obscure. One hypothesis is that the arrangement of amino acid/codon assignments results from selection to minimize the effects of errors (e.g., mistranslation and mutation) on resulting proteins. If amino acid similarity is measured as polarity, the canonical code does indeed outperform mo...
