The main objective is to clarify how mechanical properties and fracture are affected by the toughness ratio between cell walls and matrix. Cell microstructures are generated using an approach combining the discrete element method to define a spatial distribution of sites (particle centers) and a Voronoi-Laguerre tessellation built on these sites to generate the cell topology. A parametric study is then carried out by varying the toughness ratio β by a factor of five, with ten repetitions per β value. The modulus of elasticity evolves as a power-law function of β. Stress distributions and maps show that stress concentrations are strongly influenced by pore distribution and only weakly by β. An important point was to highlight the dependence of fracture regimes on the β parameter, with a value of β≃3 separating a regime where the fracture passes through the walls and a regime where it bypasses the cells and remains confined within the cohesive matrix, as has been observed in the literature.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055507"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a recent study [Phys. Rev. E 109, 044149 (2024)2470-004510.1103/PhysRevE.109.044149], these effects were analyzed within the framework of the time-delayed Newton's law of cooling under the assumption of instantaneous temperature quenches. Here, the analysis is extended to incorporate finite-rate quenches, characterized by a nonzero quench duration σ. The results indicate that a genuine Mpemba effect is absent under finite-rate quenches if both samples experience the same thermal environment during the quenching process. However, if σ remains sufficiently small, the deviations in the thermal environment stay within an acceptable range, allowing the Mpemba effect to persist with a slightly enhanced magnitude. In contrast, the Kovacs effect is significantly amplified, with the transient hump in the temperature evolution becoming more pronounced as both the waiting time and σ increase. These findings underscore the importance of incorporating finite-time effects in nonequilibrium thermal relaxation models and offer a more realistic perspective for experimental studies.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5-2","pages":"055402"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spatial configuration of trees is modeled either by uncorrelated percolation with occupation probability p or by correlated percolation using the Ising model with an artificial temperature T, which controls correlations. The burning clusters are shown to exhibit a depinning transition at a p-dependent critical β_{c} (or T-dependent in the correlated case), with critically pinned states indicating that β acts as a driving force. For uncorrelated percolation, the critical exponents for nonfractal observables place the transition in the percolation universality class, while the hull fractal dimension varies from 1.34(1) at p=1 to 1.73(2) at p=p_{c}, showing that introducing correlation in the spatial structure changes the OP universality class to a new universality class for the driven interfaces.

However, limited works have been conducted on the swimming behavior of C.reinhardtii, a typical \"puller\" type cell, near solid surfaces, particularly with varying and conflicting experimental observations. Here, we investigate the swimming behavior of C.reinhardtii using a three-dimensional real-time tracking microscopy system both near a solid-liquid interface and in the fluid bulk region. We explore the relationships between the cell density, swimming speed and orientation with respect to the distance from the solid-liquid interface, confirming the phenomenon of C.reinhardtii accumulation near the solid-liquid interface. Based on the traditional definitions of \"pusher\" and \"puller\" cells, we propose a simplified model consisting of a pair of mutually perpendicular force dipoles for C.reinhardtii. This model is employed to analyze the complex hydrodynamic interactions between C.reinhardtii and the solid surface, providing a potential theoretical explanation for the observed accumulation phenomenon at the solid-liquid interface.","PeriodicalId":48698,"journal":{"name":"Physical Review E","volume":"111 5","pages":"L052401"},"PeriodicalIF":2.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
