Summary: Double-layer metal structures with certain distance between them show strong fields coupling. In this study, the terahertz transmission properties of a composite slab composed of double-layer metal complementary periodic cross-shaped resonators (CPCRs) were investigated. By adjusting the spacing between two metal layers and introducing a dielectric layer, multi-band filters and manipulation of transmission properties were achieved. The composite slab has the potential for high sensitivity molecular fingerprint detection and narrow bandwidth filters in terahertz regions.

The ZrP nanosheets were well distributed and oriented in a polyvinyl alcohol (PVA) matrix. The coated PLA films showed high clarity even with a high percentage of ZrP nanosheets. The resulting nanocomposites exhibited improved barrier properties and mechanical strength compared to neat PVA.

Summary: In this study, the effects of a few percent diphenyl contents on the macroscale viscoelasticity of polysiloxane material were investigated through mechanical tests and finite element simulations. It was found that the degree of cross-linking did not significantly alter the microstructure, but had profound effects on the viscoelastic response of the copolymer networks. Even a small increase in the molar ratio of the diphenyl component slowed down the relaxation of the copolymer chains.

The width of the medial and lateral meniscus increased and then decreased over 26 weeks postoperatively. The extracellular matrix initially decreased and then increased to almost normal, with significant differences in the percentage of ECM between the posterior and central regions of the medial meniscus.

Summary: In this study, a knitted PET patch was used as a nondegradable synthetic graft for bridging reconstruction of massive rotator cuff tears (MRCTs) in a rabbit model. The results showed that the PET patch not only provided mechanical support but also promoted enthesis and tendon regeneration. The PET group exhibited similar graft-bone interface scores as the autograft group, and had higher tendon maturing scores and improved collagen fiber organization. Thus, the knitted PET patch shows great promise as a graft option for MRCTs.

Summary: Anderson localization of phonons was observed in aperiodic boron nitride/carbon nanotube superlattices. The coexistence of aperiodicity and interfacial mixing was found to decrease thermal conductivity, while anharmonicity destroyed phonon localization at high temperatures. This work provides insights for designing thermoelectric materials with low thermal conductivity.

Summary: This study introduced two new flocculation methods to solve the conflict between PCC filling and AKD sizing for paper: separate flocculation of AKD and PCC, and blending of pre-flocs from AKD and PCC. The results showed that increasing the dosage of cationic starch (CS) flocculant led to improved sizing degree and filler retention rate, as well as enhanced mechanical properties of papersheets. These findings demonstrate the importance of flocculation methods in optimizing paper production processes.

Summary: The unmixing-based spatiotemporal fusion model is an effective method to overcome limitations in temporal and spatial resolution tradeoffs of a single satellite sensor. However, the performance of the model may vary due to different setups and the unmixing function's ill-posed characteristic. This study analyzes the stability of the model by focusing on three major factors: definition of homogeneous change regions, unmixing levels, and number of change regions.

Summary: In this paper, three statistical metrics are proposed to evaluate the performance of tropospheric corrections in InSAR monitoring. A time series decomposition method is used to estimate tropospheric noise and mitigate bias caused by ground displacement. The root-mean-square values of tropospheric noise are calculated to assess overall correction performance, along with semi-variograms and Spearman's rank correlation to evaluate signal reduction and topography-correlated signal mitigation. The roles of primary and secondary components in InSAR tropospheric corrections are analyzed for the first time.

Summary: A object-oriented remote sensing image change detection method based on a color co-occurrence matrix is proposed to address the misdetection problem caused by the lack of correlation among multiple bands in traditional texture characteristic extraction model. The image is divided into multi-scale objects by graph-based superpixel segmentation, and the multi-channel texture features based on the color co-occurrence matrix (CCM) are extracted. A cumulative backward search strategy (CBSS) is designed to find representative features to overcome feature redundancy. The proposed algorithm achieves higher detection accuracy than texture features without band correlation, as demonstrated through qualitative and quantitative analyses using Sentinel-2 and Skysat images in Shenzhen and Dapeng.
