Within the canonical ensemble framework, this paper investigates the presence of higher-order transition signals in the q-state Potts model (for q≥3), using two geometric order parameters: isolated spins number and the average perimeter of clusters. Our results confirm that higher-order transitions exist in the Potts model, where the number of isolated spins reliably indicates third-order independent transitions. This signal persists regardless of the system's phase transition order, even at higher values of q. In contrast, the average perimeter of clusters, used as an order parameter for detecting third-order dependent transitions, shows that for q=6 and 8, the signal for third-order dependent transitions disappears, indicating its absence in systems undergoing first-order transitions. These findings are consistent with results from microcanonical inflection-point analysis, further validating the robustness of this approach.

Importance: It remains uncertain whether surgical evacuation improves functional outcomes in patients with supratentorial intracerebral hemorrhage (ICH).
Objective: To compare the safety and efficacy of minimally invasive surgery with the Artemis Neuro Evacuation Device to guideline-based medical management alone for spontaneous supratentorial ICH.
Design, Setting, And Participants: The MIND open-label, multicenter randomized clinical trial randomized patients with spontaneous supratentorial ICH in a 2:1 ratio to either minimally invasive surgery or medical management alone.

Wetting phenomena are relevant in several technological applications, particularly those involving hydrophobic or hydrophilic surfaces. Many substrates support multiple wetting states depending on surface conditions or droplet history-a behavior known as metastability. This feature is crucial both for its theoretical complexity and for its relevance in practical applications that rely on controlling metastable states.

Background: Excessive daytime sleepiness (EDS) is a complex sleep problem that affects approximately 33% of the United States population. Although EDS usually occurs in conjunction with insufficient sleep and other sleep and circadian disorders, recent studies have shown unique genetic markers and metabolic pathways underlying EDS. Here, we aimed to further elucidate the biological profile of EDS using large-scale single- and pathway-level metabolomics analyses.

The investigation of nonequilibrium thermodynamics in quantum many-body systems underscores the importance of quantum work, which differs from its classical counterpart due to its statistical nature. Recent studies have shown that quantum work can serve as an effective indicator of quantum phase transitions in systems subjected to sudden quenches. However, the potential of quantum work to identify thermal phase transitions remains largely unexplored.

We investigate the multipartite mutual information between N discrete-state stochastic units interacting in a network that is invariant under unit permutations. We show that, when the system relaxes to fixed point attractors, multipartite correlations in the stationary state either do not scale extensively with N or the extensive scaling is not robust to arbitrarily small perturbations of the system dynamics. In particular, robust extensive scaling cannot occur in thermodynamic equilibrium.
