It is maintained in nature through three transmission pathways: systemic, non-systemic and transovarial. Understanding the relative contributions of these transmission pathways is crucial for developing evidence-informed public health interventions to reduce its spillover risks to humans. Using next-generation matrices, sensitivity analyses, elasticity analyses and random forest models, we estimated the basic reproduction number R0, relative contribution of each pathway, and identified the most sensitive model parameters across 27 scenarios. Results showed that [Formula: see text] ranged from 0.72 to 2.08 across scenarios, increasing with higher tick abundance and longer viraemia. Transovarial transmission dominated in 26 scenarios, while the importance of the other two varied, with non-systemic transmission more important under high tick abundance, short viraemia or aggregated tick distribution. [Formula: see text] dropped below 1 in all scenarios when transovarial transmission was excluded. These findings emphasize the need for interventions targeting transovarial transmission, such as reducing female adult tick survival and limiting large vertebrate host movement, and underscore the importance of laboratory studies measuring sensitive parameters including transovarial transmission efficiency, tick survival probabilities and the duration of viraemia and potential for non-systemic transmission for key animal host species with high seroprevalence rates.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250140"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419887/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These experiments can be summarized with key parameters that facilitate objective comparisons across various cell and particle pairs, such as the particle-cell association rate. Previous studies often focus on point estimates of such parameters and neglect heterogeneity in routine measurements. In this study, we develop an ordinary differential equation-based mechanistic mathematical model that incorporates and exploits the heterogeneity in routine measurements. Connecting this model to data using approximate Bayesian computation parameter inference and prediction tools, we reveal the significant role of heterogeneity in parameters that characterize particle-cell interactions. We then generate predictions for key quantities, such as the time evolution of the number of particles per cell.

We identified eight major hull colours to represent the full colour spectrum and applied principal component analysis to divide each nut into seven spatial sections. Within each section, we constructed eight colour-based feature variables (covariates) and associated them with a binary response variable indicating kernel presence or absence. We explored the specific response-covariate relationships at each developmental time point using a data-driven method called categorical exploratory data analysis, which identified key first-order and second-order feature-categories that link hull colour patterns with kernel status. These relationships were visualized using block-structured heatmaps, revealing consistent distinctions between filled and blank nuts.

Understanding how the weather is associated with SARS-CoV-2 transmissibility can enhance projections of COVID-19 incidence and improve estimation of the effectiveness of control measures. During the pandemic, transmissibility was tracked by the reproduction number Rt. This study aims to determine whether information about the daily temperature, absolute humidity and solar radiation improves predictions of Rt in The Netherlands from 2020 to 2022, and to quantify the relationship between Rt and daily weather data. We conducted a regression analysis, accounting for immunity from vaccination and previous infection, higher transmissibility of new variants and changes in contact behaviour due to control measures. Results show a linear association between logRt and daily solar radiation and temperature, indicating a ratio of Rt in winter versus summer of 1.7 (95% CI, 1.4; 2.1). The possibility that this association arises from unrelated seasonal patterns was dismissed, as weather data from earlier years provided poorer fits with only small effect sizes. This suggests a causal relationship between solar radiation and temperature with SARS-CoV-2 transmissibility, enhancing confidence in using this relationship for short-term predictions and other epidemiological analyses.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250317"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we explore the hypothesis that the coiled structure of the umbilical cord could strengthen diffusive coupling between the arteries and the vein, resulting in a functional shunt. We calculate the diffusion of solutes, such as oxygen, and heat in the umbilical cord to quantify how this shunt is affected by vascular configuration within the cord. We demonstrate that the shunt is enhanced by coiling and vessel proximity. Furthermore, our model predicts that typical vascular configurations of the human cord tend to minimize shunting, which could otherwise disrupt thermal regulation of the fetus. We also show that the exchange, amplified by coiling, can provide additional oxygen supply to the cord tissue surrounding the umbilical vessels.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250148"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12457040/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145131149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bacteria reproduce exponentially via 2n growth kinetics and thus must respond to changing nutrient availability to reproduce rapidly during short periods of feast and survive during long periods of famine. Type II TASs represent stable enzyme-unstable inhibitor systems that are regulated by reversible competitive inhibition, which allows them to efficiently produce pleiotropic effects on prokaryotic cells in a continuous (analogue) manner due to varying concentrations of free toxin throughout the life cycle. A nutrient-responsive cybernetic system (NRCS) model is proposed where intracellular nutrient concentration feeds back to control the emergent properties of growth, death and growth/death arrest, which results in a novel fitness strategy termed K Sensing and Control. When nutrients become limiting, alternative general stress response sigma factors ϬS and ϬB regulate the expression of hundreds of genes that may control the transformation of vegetative bacteria into coccoid, stress-tolerant 'motherspores'. An integrated NRCS model is presented that shows how TASs and sigma factors may work in concert to efficiently regulate population dynamics, cellular physiology and cellular differentiation throughout the life cycle, which optimizes the biological fitness of free-living bacteria.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250185"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12440627/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crack propagation follows the path of least resistance or the lowest fracture toughness. Previous work showed that applying asymmetrical stress to burrow walls to simulate steering had minimal effect on crack propagation direction, suggesting that crack branching or the fusing of microcracks near the crack tip with the main burrow allows for burrowers to navigate by choosing between two directions. Here we use the lattice element method for modelling of fracture in heterogeneous materials to examine how fracture toughness, variability in fracture toughness and worm behaviours affect crack branching and microcracking. Experimental observations of worms burrowing in custom-built ant farm tanks support the modelling results that burrowing activities create microcracks both within the vicinity of the crack tip and in the surrounding sediment. In addition, hydraulic fracture driven by burrow irrigation reduces microcracking outside of the fracture process zone, potentially increasing the efficiency of burrowing. These results highlight the potential feedback between burrowing activities and sediment heterogeneity that characterize ecosystem engineering of sediment habitats by infaunal burrowers.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250113"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12441751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we show that variations in a listener's facial temperature, a marker of the autonomic emotional response, reflect the pain expressed by a baby's cry. Specifically, by conducting listening experiments with cries expressing mild discomfort or acute pain, we demonstrate that NLP modulate the facial thermal response in adult listeners, irrespective of sex and of cry pitch variation. The temporal dynamics of the thermal response is more closely synchronized with the amplitude envelope of the acoustic signal when listening to a cry containing a large level of NLP than when NLP are less prominent. The pain encoded in a baby's cry thus generates a synchronized emotional response in both adult men and women, emphasizing that our ability to decode the information carried by babies' cries integrates an immediate activation of the autonomic nervous system before engaging higher-order cognitive processes.","PeriodicalId":17488,"journal":{"name":"Journal of The Royal Society Interface","volume":"22 230","pages":"20250150"},"PeriodicalIF":3.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12419898/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As iridescence in golden moles is created through a thin-film mechanism from a compressed cuticle structure, and the structure of hair is highly conserved, we expect iridescence to be present, and produced by the same mechanism, in mammals that share similar hair properties. Here, we test this hypothesis by first collecting and analysing existing documentation of iridescence in mammals, finding written evidence spanning 25 genera across eight mammalian families. We then identified the underlying mechanisms of iridescence for 14 species from Rodentia and Afrosoricida (including one outside Chrysochloridae), and showed that iridescence in these species is created through the same system of thin, alternating layers of keratin and probably lipid-rich material within the cuticle, in similar proportions as Chrysochloridae.
