Summary: This research studies the tunable underwater low-frequency sound absorption of locally resonant piezoelectric metamaterials (LRPM). A theoretical model is established to analyze the tunable sound absorption characteristics and perfect absorption mechanism from the perspective of effective materials. The theoretical results are in good agreement with the numerical ones. The research shows that a thin LRPM layer can achieve perfect sound absorption at targeted low-frequency, which can be actively tuned by manipulating the resonant shunt circuit. Furthermore, introducing negative capacitance (NC) shunt significantly improves the sound absorption bandwidth. The study also discusses the causal constraints and its improvement by NC shunt, providing guidance for efficient and widely adjustable ultra-thin underwater sound absorbers.

Summary: We designed and demonstrated a nearly perfect low-frequency sound absorption in subwavelength H-fractal metamaterials by continuously tuning the absorption peak frequency through changing the opening positions. Moreover, we successfully decreased the total thickness of the acoustic metamaterial to & lambda;/92.2 by increasing the number of openings. The underlying mechanism is the impedance matching caused by additional couplings from new openings. The experimental results agree well with numerical analyses, and this proposed method offers a new route for reducing the thickness of sound-absorbing materials with potentially wide application demands in the field of noise control.

Summary: We propose a theoretical design and experimental authentication of an ultrathin sound absorber that consists of a perforated plate and a back cavity with zigzag channels for high-efficiency and broadband absorption of low-frequency sound. The dependency of absorption performance on structural parameters is analyzed, suggesting the possibility of decreasing the resonance noise absorption peak frequency while maintaining compactness. We also propose a hybrid design composed of multiple structures with different parameters and suggest further optimization by adjusting the inclined partitions in the zigzag channel to enhance low-frequency absorption. Experimental results show nearly 100% sound absorption at resonance frequency (< 500 Hz) with an absorber 30 times thinner than the wavelength. This designed sound absorber with deep-subwavelength size, broadband functionality, and easy fabrication has potential applications in noise control engineering.

Summary: This article considers the consensus problem of unknown linear multiagent systems (MASs) through adaptive event-driven control in both leader-follower and leaderless networks. The proposed event-driven algorithms are fully distributed and do not require any global information related to the network structure. They achieve consensus by only relying on local information exchange. Unlike other algorithms, the control algorithms in this article are not dependent on the dynamics parameters of each agent and therefore do not require precise information about the MAS dynamics. The article also proves the existence of a strict positive lower bound between any two adjacent events, effectively excluding the possibility of Zeno behavior for each agent. The effectiveness of the proposed algorithms is further demonstrated through a simulation example.

Summary: This paper addresses the problem of observer-based mismatched faults for switched singular fuzzy systems subject to disturbances. First, a fuzzy adaptive observer is obtained to estimate unmeasurable or partially measurable states while eliminating the influence of external disturbances and mismatched faults. Second, by constructing appropriate piecewise Lyapunov functions and average dwell time, the stability of the switched singular fuzzy stochastic system with external parameter perturbations and faults is guaranteed. Furthermore, a sufficient condition to maintain the stability of the error dynamic system is presented by solving linear matrix inequalities.

Summary: High entropy alloy (HEA) nanoparticles are formed by aggregation of metal cluster intermediates, rather than nucleation and growth, according to this study utilizing liquid phase transmission electron microscopy (LPTEM), systematic synthesis, and mass spectrometry (MS). The researchers used aqueous co-reduction of metal salts with sodium borohydride in the presence of thiolated polymer ligands to synthesize AuAgCuPtPd HEA nanoparticles. The size of the nanoparticles increased with increasing supersaturation ratio, supporting an aggregative growth mechanism. The findings highlight the importance of cluster species as potential synthetic handles for controlling the atomic structure of HEA nanoparticles.
