Typically, the former occurs with little attachment of the particles to the rebounding droplet, while the latter emerges with the signature of a liquid marble formation. We propose a simplified model to predict the contact time of the droplet on the superhydrophobic particles by considering the additional surface deformation underneath the droplet and the possible formation of a liquid marble induced by the particles. This proposed model not only supplies the upper and lower bounds of the contact time that covers all the experimentally measured data, but also provides a way to estimate the effective viscosity in the liquid-particle mixture, which collapses the maximum spreading factor of all tested impact cases to one curve.</p>","PeriodicalId":20085,"journal":{"name":"Physical review.

To achieve this, we propose a method to identify moments of high and low team performance based on the analysis of match events. This approach enables the construction of sets of temporal passing networks associated with each performance context. By analyzing topological metrics such as clustering, eigenvector centrality, and betweenness across both sets, significant structural differences are identified between moments of high and low performance. These differences reflect changes in the interaction dynamics among players and, consequently, in the team's playing system. Subsequently, a logistic regression model is employed to classify high- and low-performance networks. The analysis of the model coefficients identifies which metrics need to be adjusted to promote the emergence of structures associated with better performance. This framework provides quantitative tools to guide tactical decisions and optimize playing dynamics. Finally, the proposed method is applied to address the \"blocked player\" problem, optimizing passing relationships to minimize the emergence of structures associated with low performance, thereby ensuring more robust dynamics against contextual changes.</p>","PeriodicalId":20085,"journal":{"name":"Physical review.

We explore whether diffusion models can enhance parameter inference by augmenting small datasets. Our findings demonstrate this potential through a synthetic task involving inverse Ising inference and a real-world application of reconstructing missing values in neural activity data.

{"title":"Effect of gravity-induced shape change on the diffusion-limited evaporation of thin sessile and pendant droplets.","authors":"Hannah-May D'Ambrosio, Stephen K Wilson, Alexander W Wray, Brian R Duffy","doi":"10.1103/PhysRevE.111.045107","DOIUrl":"https://doi.org/10.1103/PhysRevE.111.045107","url":null,"abstract":"<p><p>A comprehensive study of the effect of gravity-induced shape change on the diffusion-limited evaporation of thin sessile and pendant droplets on a horizontal substrate is performed. Specifically, theoretical predictions for the evolution, and hence the lifetime, of sessile and pendant droplets evaporating in four modes of evaporation, namely, the constant contact radius (CR), the constant contact angle (CA), the stick-slide (SS), and the stick-jump (SJ) modes, are obtained. In particular, it is shown that gravity-induced shape change can cause quantitative differences in the evolution of sessile and pendant droplets compared to that of a droplet in the absence of (or in the neglect of) the effect of gravity (a \"zero-gravity droplet\"). For example, whereas sessile and pendant droplets evaporating in the CR mode evolve in qualitatively the same manner as a zero-gravity droplet, the evolution of droplets evaporating in the CA mode is more complicated. Specifically, while a zero-gravity droplet evaporating in the CA mode evolves according to the well-known d^{2} and 2/3 laws, an initially large sessile droplet evolves according to qualitatively different d and 1/2 laws, and an initially large pendant droplet evolves with the contact radius and the volume (but not, of course, the contact angle) behaving as if the droplet was evaporating in the CR mode. It is also found, perhaps somewhat unexpectedly, that the maximum height of a sessile droplet evaporating in the CA mode is a nonmonotonic function of time when the initial volume of the droplet is sufficiently large. Furthermore, it is found that for all four modes of evaporation a sessile droplet always evaporates faster, and hence has a shorter lifetime, than a zero-gravity droplet with the same initial volume, which in turn always evaporates faster, and hence has a shorter lifetime, than a pendant droplet with the same initial volume. It is also shown that for all four modes of evaporation the lifetime of a droplet is a monotonically increasing function of the initial volume of the droplet, that the lifetime of a droplet evaporating in the CA mode is always longer than that of the same droplet evaporating in the CR mode, and that the lifetimes of droplets evaporating in the SS and SJ modes both always lie between the lifetimes of the same droplet evaporating in the extreme modes.</p>","PeriodicalId":20085,"journal":{"name":"Physical review.

In this paper, we investigate the nonlinear phenomena caused by charge carrier motion at the gap of a single SRR operating in the terahertz (THz) frequency range. Unlike previous approaches, our model incorporates an additional controlled field to adjust the loss parameter, providing a more generalized framework for understanding nonlinear behavior in SRRs. The nonlinear dynamics are revealed by the two-parameter space diagrams, which allow us to identify periodic and chaotic oscillations for different parameter sets of the nonlinear SRR material. In order to explore the multifunctionality of the material, we construct two-dimensional diagrams by sweeping each parameter in two directions for the same initial values and we find a plethora of hysteresis regions, demonstrating the interesting phenomenon of multistability. Our results show that this behavior occurs in extremely large dynamic regions for all cases studied, favoring the coexistence of up to three different signals/attractors. The different types of multistable patterns are studied in the cross-section of the demarcation region and presented as the coexistence of chaotic with periodic states, and the coexistence of only periodic states. We analyze the parallel branches in hysteresis regions, and we identify a parallel branch in some range where the bifurcation presents a jump. According to our results, the parallel branch has a key impact on multistability, since it increases the number of coexisting states. However, it appears in a very tiny range of parameters and annihilates after a collision crisis. Finally, we analyze the influence of the loss parameter on nonlinear material dynamics using two-parameter spatial diagrams, demonstrating that control of the loss parameter can gradually eliminate the presence of chaotic behavior, thus serving as a pivotal control mechanism for future applications.</p>","PeriodicalId":20085,"journal":{"name":"Physical review.
