Summary: This study investigated the stability of municipal solid waste (MSW) landfills by analyzing the effects of landfill age and moisture content on the shear strength of MSW. The results demonstrate that both landfill age and moisture content have a significant impact on the shear strength, cohesive force, and internal friction angle of MSW.

Summary: Research indicates that spectroscopy of Stark-localized states can effectively map the surface curvature of nanostructures. By varying the field direction, local curvatures can be extracted from absorption spectra, and it has been shown that the required field strength is feasible experimentally.

Summary: This paper proposes a self-optimization algorithm based on electrostatic field to solve the influence maximization problem in high-order networks. By treating the network as an electrostatic field, the interaction forces between nodes are revealed. Experimental results demonstrate the superiority of the proposed algorithm over six other algorithms on real-world networks.

Summary: A new shear stress model of MRPF is proposed in this study, which explains the relationship between the number of sliding particles and shear rate using an exponential function. The theoretical model effectively explains the variation of shear stress with shear rate compared to experimental data. The correctness of the particle slip hypothesis has been verified by finite element method.

Summary: A novel colorimetric probe, SPNO, was successfully synthesized and characterized. The probe displayed remarkable selectivity and sensitivity for the detection of Au3+ in a 1,4-dioxane-H2O solution. The detection limit of Au3+ was determined to be 335 nM. SPNO-coated test strips were also prepared and demonstrated to be applicable for highly sensitive detection of Au3+ in mixed 1,4-dioxane:water solutions.

Summary: In this study, a peptide-QDs composite fluorescent probe was developed for high-performance imaging and early diagnosis of dental caries caused by the primary bacteria S. mutans. The probe exhibited high fluorescence stability, good biocompatibility, and low biotoxicity in physiological environments. It enabled specific recognition and fluorescence labeling of S. mutans, accurately locating early carious lesions and susceptible sites. Combined with visible fluorescence analysis, it provided a more convenient screening method for hidden dental lesions. The peptide-QDs composite fluorescent probe can be widely used in routine dental examinations for accurate screening of dental diseases due to its low synthesis cost, stable storage, and simple imaging method.

Summary: 6'-(indolin-1-yl)-1-(4-methoxybenzyl)-3,3-dimethylspiro[indoline-2,3'-naphtho[2,1-b][1,4]oxazine] (SPO) is a novel colorimetric probe with superior selectivity and sensitivity for CH3Hg+ detection in a 1,4-dioxane solution. Complexes of SPO with Hg2+ or CH3Hg+ were formed at a 1:1 mol ratio, with detection limits in the nM level in 1,4-dioxane. Test strips coated with SPO also showed highly sensitive detection of CH3Hg+ in mixed 1,4-dioxane:water solutions.

Summary: Revealing the mechanism of interface-type resistive switching is challenging and requires direct observation of the buried interface. Using a memory device based on the MoS2/Nb:SrTiO3 heterojunction, this study investigated the resistive switching mechanism. The results showed an apparent hysteresis loop and resistive switching phenomenon between high and low resistance states. The surface potential of MoS2 and its PL spectrum also varied with the resistance state, confirming the interface charge trapping/ detrapping mechanism.

Summary: This paper investigates the use of the virtual element method to solve frictional contact problems with normal compliance conditions. Existence and uniqueness results for the discretized scheme are obtained, along with an a priori error analysis and an optimal error bound for the lowest order virtual element method. A numerical example is provided to demonstrate the efficiency of the method and validate the theoretical error estimate.

Summary: The paper presents an efficient design approach based on Coulomb's law for generating well-shaped and fluent grids for free-form grid structural design. By considering nodes as interacting particles in an electric field, the method adds nodes to the surface progressively and connects particles in equilibrium to generate the grid. Two variations of the method, point-based progressive method (PBPM) and curve-based progressive method (CBPM), are introduced based on different ways of adding particles.
