However, the day-to-day experience and psychological recovery from social deprivation, especially among individuals with high trait anxiety, remains poorly understood. We conducted a 10-day longitudinal study with 116 university students returning to campus, collecting approximately 31 000 momentary assessments of affect and social interactions during a 3-day quarantine and subsequent period. Quarantine increased the need for social interaction and altered patterns of social engagement, whereas trait anxiety was robustly associated with reduced positive affect and elevated negative affect. Close interactions following quarantine were associated with higher positive affect. We also administered a virtual patch-foraging task to participants during and after quarantine. Greater variability in negative affect was associated with lower patch exit thresholds, suggesting a tendency to persist in depleted patches. These findings highlight how trait anxiety shapes emotional experience and social behaviour in daily life and reveal how fluctuations in negative affect can influence sequential decision-making under uncertainty.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"251773"},"PeriodicalIF":3.0,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13673250/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149216853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

However, these labels do not define invariant molecular properties. A molecule may realize different functions depending on reaction partner, local coupling, spatial domain and prior trajectory. Function is therefore not primitive but emergent. Here, we develop a mathematical theory of redox biology from first principles. At the mesoscopic level, chemically defined molecular states are treated as objects and reactions as transformations, yielding an admissible biochemical state space naturally represented as a hypergraph. Function is then defined as a derived relational quantity induced by realized flux over this structural network. As realized flux is temporally mutable, function is necessarily dynamic. By introducing locality, the realized redox state is mathematically represented as an informational occupancy field over space and time. This field is bounded, admits geometric deformation and provides a formal basis for memory, attractors and coarse-grained scalar descriptions like oxidative stress. Measurement and manipulation are treated as coupled informational interfaces to this field, bounding causal inference. The theory yields falsifiable predictions, including flux-dependent function at fixed concentration and history-dependent responses under matched present inputs.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"260547"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641906/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In doing so, it offers an explanation for the characteristic ventilation heterogeneity (or clustered ventilation defects) seen in asthma. The terminal airway bistability is based on the Anafi-Wilson model, and this is embedded and extended into a symmetric bifurcating airway tree, in which an enforced tidal volume target and an imposed degree of airway smooth-muscle activation interact to generate spatially structured ventilation patterns. Here, we provide the first open-source implementation of the Venegas-Winkler bronchoconstriction cascade model and use it to identify several previously undescribed properties: both the tree depth and wall thickness assumptions affect the bifurcation onset, tidal volume and acinar elastance assumptions require careful interpretation for a model at sub-lung scale and airway geometry assumptions strongly affect driving pressures and bifurcation cascade characteristics.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"261168"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641895/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Ionic liquids (ILs) are considered highly promising absorbents. However, their vast chemical space poses significant challenges for experimental screening. In this study, Morgan fingerprint descriptors were combined with a stacking ensemble learning algorithm, and SHapley Additive exPlanations (SHAP) analysis was employed to develop an accurate and interpretable framework for predicting CO2 solubility. The stacking ensemble model employs the light gradient boosting machine and the backpropagation neural network as base learners. The dung beetle optimizer and the grey wolf optimizer were used to determine optimal hyperparameter combinations for these learners, while linear regression was adopted as the meta-learner to produce the final CO2 solubility prediction. The results demonstrate that the stacking ensemble algorithm achieves the highest predictive accuracy, attaining a test-set coefficient of determination (R 2) of 0.9888, a mean absolute error of 0.0149 and a mean squared error of 0.0006. SHAP analysis further reveals that the [Tf2N] (bis(trifluoromethylsulfonyl)amide) anion exerts the most significant influence, followed by the alkyl chain length of imidazolium cations. Accordingly, combining the [Tf2N] anion with imidazolium cations bearing longer alkyl chains represents a promising strategy for synthesizing ILs with high CO2 absorption efficiency.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"260335"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641916/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149128506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

However, the prevailing structures of academic institutions tend to be based on specialized disciplinary knowledge and expertise, rather than cross-disciplinary synthesis of the insights from disciplinary knowledge and expertise, reflexivity and holistic approaches. As such, the existing model for generating 'excellence' in novel and specialized research does not lend itself to the synthesis of existing disciplinary insight, where the long-term goals and short-term metrics of success are different. There is, therefore, a need to create opportunities for a new and complementary conceptual methodological approach to address persistent complex challenges. This paper proposes two tools designed to facilitate thinking about what types of disciplinary knowledge and expertise can be relevant to tackling complex challenges, and to identify what questions might spark productive and unconventional dialogues across disciplines that result in interdisciplinary insight. Approaching complex challenges using these tools addresses the need to deal with different facets of the challenge in concert, and the need for effective juxtaposition and combination of knowledge and expertise from multiple disciplines to develop interdisciplinary insight and approaches to craft questions and address the challenge.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"252200"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641920/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

However, the evolutionary history of these carnivorans is still not fully understood. To explore this topic, we studied the bite of two fossil close relatives of the modern grey wolf, Canis borjgali and Canis mosbachensis, through digital bite simulations via finite element analysis (FEA). We used computer simulations based on computed tomography (CT) scans of fossil skulls to recreate how these animals catch and chew their prey. These simulations allowed us to test how their skulls react during different types of bites. To improve our analysis, the bite performance of C. borjgali and C. mosbachensis was compared with those of a selection of living canids having different diets. Our results suggest that C. borjgali had a relatively strong skull capable of handling hard food (such as bones). On the other hand, C. mosbachensis showed higher stress on its skull during the bite simulations, which means that its skull was somewhat weaker. Moreover, the FEA bite simulation evidence shows that the frontal sinuses (a pair of cavities located in the frontal bones) play a key role in dealing with bite-related stress, especially in a canine bite scenario.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"261396"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641898/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

To assess possible effects of tephra exposure on coral physiology, we conducted controlled culture experiments with three scleractinian corals (Stylophora pistillata, Turbinaria reniformis and Pocillopora damicornis) exposed to weekly additions of 50 g of untreated tephra, collected from the volcanic island of St. Vincent, and its leachate over a six-week period. All exposed colonies experienced optimized photosynthetic light-harvesting processes, while most other physiological parameters were not affected. Remobilized tephra supplies hormetic concentrations of water soluble trace metals, with high-resolution inductively coupled plasma mass spectrometer (HR-ICP-MS) analyses showing significant increases in seawater trace metal (V, Mn, Fe, Co, Ni, Cu, Cd and Pb) concentrations.

Greater distances of high-speed galloping accumulated during racing campaigns are associated with MSI. Bone injury is the most common MSI, and understanding how training practices influence bone damage accumulation is critical for improving both horse welfare and racing outcomes. This study builds on an existing mathematical model of bone adaptation and damage to investigate the impact of different training programmes on bone injury risk. Several training programmes (three progressive, four race-fit, six rest programmes and two with rest replaced by low-intensity training) were constructed to reflect representative practices undertaken by professional trainers in Victoria, Australia. Training programmes varied in training volume, rest frequency and programme duration. Lower-volume training programmes that included high-speed training achieved sufficient bone adaptation with less accumulation of bone damage, and subsequently lower risk of bone failure. In addition, incorporating more frequent rests (minimum of two per year) and/or longer rest periods (minimum of six weeks) reduced bone damage owing to the extended opportunity to remove and repair bone damage. These results provide an in silico mathematical model of the bone's response to training, demonstrating the effects of training programmes on bone adaptation, damage formation and repair. The findings can guide the design of training programmes that balance both bone adaptation and bone health throughout a horse's racing career.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"260818"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641913/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Microbial biofilms act as positive cues for larval settlement across species, yet the behavioural processes preceding settlement are poorly understood. Here, we investigated age-dependent changes in settlement behaviour in marine polychaete Platynereis dumerilii larvae in response to Grammatophora marina diatom biofilms. Settlement behaviours (crawling, crawling speed and track straightness) were quantified from recordings of larvae ranging from the mid-trochophore to late-nectochaete in the presence or absence of diatom biofilms, using spot-tracking software. As larvae developed, the proportion of individuals crawling over the biofilm increased. Older larvae colonized biofilms more rapidly and showed greater discrimination between G. marina biofilms and controls. Older larvae straighten their movements compared with individuals swimming in the presence of biofilms, or behaviour witnessed in the absence of biofilms. The prevalence of these behaviours may reflect changes in the prioritization of sensory inputs from physical and chemical cues as larvae develop. Our findings suggest that settlement behaviours are developmentally programmed in P. dumerilii. Understanding settlement behaviours in P. dumerilii expands on this species' behavioural repertoire and sheds light on the evolutionary relationship between marine larvae and microalgal biofilms.","PeriodicalId":21525,"journal":{"name":"Royal Society Open Science","volume":"13 10","pages":"261521"},"PeriodicalIF":3.0,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13641892/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149114597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
