The study of first order transition (explosive synchronization) in an ensemble (network) of coupled oscillators has been the topic of paramount interest among the researchers for more than one decade. Several frameworks have been proposed to induce explosive synchronization in a network and it has been reported that phase frustration in a network usually suppresses first order transition in the presence of pairwise interactions among the oscillators. However, on the contrary, by considering networks of phase frustrated coupled oscillators in the presence of higher-order interactions (up to 2-simplexes) we show here, under certain conditions, phase frustration can promote explosive synchronization in a network. A low-dimensional model of the network in the thermodynamic limit is derived using the Ott-Antonsen ansatz to explain this surprising result. Analytical treatment of the low-dimensional model, including bifurcation analysis, explains the apparent counter intuitive result quite clearly.

Recent findings suggest that higher-order (group) interactions provide a general pathway to explosive phenomena in networks of coupled oscillators. While these abrupt, first-order transitions, termed explosive synchronization, are of significant theoretical interest, they are often undesirable and potentially dangerous in many real-world systems. Motivated by this, we investigate a control mechanism to suppress explosive synchronization in adaptive multilayer networks incorporating higher-order interactions by introducing a phase lag into the system.

Inspired by the distinct circular coffee-ring stains left by coffee droplets, we explore another type of circular stain formed by colorimetric nanomaterials on hydrophilic and porous nitrocellulose (NC) papers, which are termed diffusion coffee rings (DCRs). Layered MoS nanosheets, utilized as colorimetric nanomaterials, exhibit an intriguing MoS-marked DCR (MoS/DCR) boundary on NC substrates. When MoS-loaded NC was immersed into HAuCl solutions, a spontaneous reaction between MoS nanosheets and Au ions results in notable color changes at the MoS/DCR due to the formation of -synthesized gold nanoparticles (issAu), and this phenomenon is termed issAu staining in our protocol.

On September 17, 2024, Lebanon experienced a mass-casualty event involving the simultaneous detonation of explosive-laden pagers, resulting in 12 fatalities and injuries to nearly 3,000 individuals, primarily involving the eyes, face, and hands. This unprecedented attack marked the first large-scale use of mass communication devices as weapons. Hospitals, particularly the American University of Beirut’s Department of Ophthalmology, faced extraordinary challenges in managing these injuries, performing over 80 vision-saving surgeries within four days.

Current systems, including target-controlled infusion (TCI) and closedloop systems, either rely on relatively static pharmacokinetic/pharmacodynamic (PK/PD) models or focus on single anesthetic control. So they limit both personalization and collaborative control.
