Utilizing the theory of Wigner-In\"{o}nu\u0000contractions, we begin with a brief review of how one can apply these\u0000contractions to the well-known Poincar'{e} algebra, yielding the corresponding\u0000Galilean (both massive and mass-less) and Carrollian algebras as $c to infty$\u0000and $cto 0$, respectively. Subsequently, we methodically apply these\u0000contractions to non-commutative $kappa$-deformed spaces, revealing compelling\u0000insights into the interplay among the non-commutative parameters $a^mu$ (with\u0000$|a^nu|$ being of the order of Planck length scale) and the speed of light $c$\u0000as it approaches both infinity and zero. Our exploration predicts a sort of\u0000\"branching\" of the non-commutative parameters $a^mu$, leading to the emergence\u0000of a novel length scale and time scale in either limit. Furthermore, our\u0000investigation extends to the examination of curved momentum spaces and their\u0000geodesic distances in appropriate subspaces of the $kappa$-deformed Newtonian\u0000and Carrollian space-times. We finally delve into the study of their deformed\u0000dispersion relations, arising from these deformed geodesic distances, providing\u0000a comprehensive understanding of the nature of these space-times.","PeriodicalId":501275,"journal":{"name":"arXiv - PHYS - Mathematical Physics","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139463818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the learning period completes, the model will predict additional\u0000observations and its parameters uniquely characterise the complement of ion\u0000channels. However, the assimilation of biological data, as opposed to model\u0000data, is complicated by the lack of knowledge of the true neuron equations.\u0000Reliance on guessed conductance models is plagued with multi-valued parameter\u0000solutions. Here, we report on the distributions of parameters and currents\u0000predicted with intentionally erroneous models, over-specified models, and an\u0000approximate model fitting hippocampal neuron data. We introduce a recursive\u0000piecewise data assimilation (RPDA) algorithm that converges with near-perfect\u0000reliability when the model is known. When the model is unknown, we show model\u0000error introduces correlations between certain parameters.

Unexpressed ionic currents are correctly filtered out even in the\u0000presence of mild model error.
