How have biological circuits learned to solve environmental\u0000challenges over the history of life? The answer certainly follows Dobzhansky's\u0000famous quote that ``nothing in biology makes sense except in the light of\u0000evolution.'' But that quote leaves out the mechanistic basis by which natural\u0000selection's trial-and-error learning happens, which is exactly what we have to\u0000understand. How does the learning process that designs biological circuits\u0000actually work? How much insight can we gain about the form and function of\u0000biological circuits by studying the processes that have made those circuits?\u0000Because life's circuits must often solve the same problems as those faced by\u0000machine learning, such as environmental tracking, homeostatic control,\u0000dimensional reduction, or classification, we can begin by considering how\u0000machine learning designs computational circuits to solve problems. We can then\u0000ask: How much insight do those computational circuits provide about the design\u0000of biological circuits? How much does biology differ from computers in the\u0000particular circuit designs that it uses to solve problems? This article steps\u0000through two classic machine learning models to set the foundation for analyzing\u0000broad questions about the design of biological circuits. One insight is the\u0000surprising power of randomly connected networks. Another is the central role of\u0000internal models of the environment embedded within biological circuits,\u0000illustrated by a model of dimensional reduction and trend prediction. Overall,\u0000many challenges in biology have machine learning analogs, suggesting hypotheses\u0000about how biology's circuits are designed.","PeriodicalId":501044,"journal":{"name":"arXiv - QuanBio - Populations and Evolution","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204372","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}

However, human-to-animal and animal-to-human transmission cannot be\u0000ignored, as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can\u0000spread rapidly in farmed and wild animals. This could create a worrying cycle\u0000of SARS-CoV-2 spillover from humans to animals and spillback of new strains\u0000back into humans, rendering vaccines ineffective. This study provides a key\u0000indicator of animals that may be potential susceptible hosts for SARS-CoV-2 and\u0000coronavirus infections by analysing the phylogenetic distance between host\u0000angiotensin-converting enzyme 2 and the coronavirus spike protein. Crucially,\u0000our analysis identifies animals that are at elevated risk from a spillover and\u0000spillback incident. One group of animals has been identified as potentially\u0000susceptible to SARS-CoV-2 by harbouring a parasitic coronavirus spike protein\u0000similar to the SARS-CoV-2 spike protein. These animals may serve as\u0000amplification hosts in spillover events from zoonotic reservoirs. Tracing\u0000interspecies transmission in multi-host environments based solely on in vitro\u0000and in vivo examinations of animal susceptibility or serology is a\u0000time-consuming task. This approach allows rapid identification of high-risk\u0000animals to prioritize research and assessment of the risk of zoonotic disease\u0000transmission in the environment. It is a tool to rapidly identify zoonotic\u0000species that may cause outbreaks or participate in expansion cycles of\u0000coexistence with their hosts. This prevents the spread of coronavirus\u0000infections between species, preventing spillover and spillback incidents from\u0000occurring.","PeriodicalId":501044,"journal":{"name":"arXiv - QuanBio - Populations and Evolution","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204371","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}

Not only in humans, but also in the cognitively-limited\u0000organisms, this interplay between the resource and the cooperation is\u0000ubiquitously witnessed. The strategically interacting players engaged in such\u0000game-environment feedback scenarios naturally pick strategies based on their\u0000perception of the environmental state. Such perception invariably happens\u0000through some sensory information channels that the players are endowed with.\u0000The unfortunate reality is that any sensory channel must be noisy due to\u0000various factors; consequently, the perception of the environmental state\u0000becomes faulty rendering the players incapable of adopting the strategy that\u0000they otherwise would. Intriguingly, situation is not as bad as it sounds. Here\u0000we introduce the hitherto neglected information channel between players and the\u0000environment into the paradigm of stochastic evolutionary games with a view to\u0000bringing forward the counterintuitive possibility of emergence and sustenance\u0000of cooperation on account of the noise in the channel. Our primary study is in\u0000the simplest non-trivial setting of two-state stochastically fluctuating\u0000resource harnessed by a large unstructured population of cooperators and\u0000defectors adopting either memory-1 strategies or reactive strategies while\u0000engaged in repeated two-player interactions. The effect of noisy information\u0000channel in enhancing the cooperation in reactive-strategied population is\u0000unprecedented. We find that the propensity of cooperation in the population is\u0000inversely related to the mutual information (normalized by the channel\u0000capacity) of the corresponding information channel.","PeriodicalId":501044,"journal":{"name":"arXiv - QuanBio - Populations and Evolution","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204216","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}

Unfortunately, modeling of stochastic diffusion\u0000is mostly done through inaccurate deterministic tools that fail to capture the\u0000random nature of dispersal or else through expensive computational simulations.\u0000In particular, standard tools fail to fully capture the heterogeneity of the\u0000area over which this diffusion occurs.

In this work, we thus\u0000explore the possible (astro)biological implications of this discovery.

Typically, they are derived from aligned sequence data (like\u0000DNA, RNA, or proteins) by using optimization criteria like, e.g., maximum\u0000parsimony (MP). It is believed that the latter is able to reconstruct the\u0000enquote{true} tree, i.e., the tree that generated the data, whenever the\u0000number of substitutions required to explain the data with that tree is\u0000relatively small compared to the size of the tree (measured in the number $n$\u0000of leaves of the tree, which represent the species under investigation).\u0000However, reconstructing the correct tree from any alignment first and foremost\u0000requires the given alignment to perform differently on the enquote{correct}\u0000tree than on others. A special type of alignments, namely so-called $A_k$-alignments, has gained\u0000considerable interest in recent literature. These alignments consist of all\u0000binary characters (enquote{sites}) which require precisely $k$ substitutions\u0000on a given tree. It has been found that whenever $k$ is small enough (in\u0000comparison to $n$), $A_k$-alignments uniquely characterize the trees that\u0000generated them. However, recent literature has left a significant gap between\u0000$kleq 2k+2$ -- namely the cases in which no such characterization is possible\u0000-- and $kgeq 4k$ -- namely the cases in which this characterization works. It\u0000is the main aim of the present manuscript to close this gap, i.e., to present a\u0000full characterization of all pairs of trees that share the same\u0000$A_k$-alignment. In particular, we show that indeed every binary phylogenetic\u0000tree with $n$ leaves is uniquely defined by its $A_k$-alignments if $ngeq\u00002k+3$.
