Summary: Rabi-like splitting and self-referenced refractive index sensing have been theoretically demonstrated in hybrid plasmonic-1D photonic crystal structures. The coupling between Tamm plasmon and cavity photon modes is achieved by incorporating a low refractive index spacer layer. The modes coupling exhibits Rabi-like splitting with different splitting energy, supported by coupled mode theory. The polarization splitting of the lower hybrid mode is stronger than that of the upper hybrid mode. The hybrid modes can be used for designing self-referenced refractive index sensors.

Summary: This study focuses on the elevated concrete water tower and investigates its ground motion response under different types of seismic waves with consideration of the liquid-solid-soil interaction. The results show that the seismic response of the water tower varies depending on the type of seismic wave. Pulsed seismic waves cause the most intense response, followed by far-field long-period seismic waves, while the response to near-field no-pulse seismic waves is minimal.

Summary: Integration of human papilloma virus (HPV) DNA into the human genome may progressively contribute to cervical carcinogenesis. We analyzed multiomics data from 50 patients with cervical cancer to explore how HPV integration affects gene expression by altering DNA methylation. High-frequency HPV-integrated genes, including five novel recurrent genes, were identified. HPV integrations occurring in exons were associated with altered gene expression in tumor tissues. Our study provides novel insights into HPV-induced cervical cancer at the biological and clinical level.

Summary: The stress characteristics of the Sejila area are preliminarily identified based on measured stress data, structural history, and features. A three-dimensional numerical model with real topographic features is established, and a distribution law of stress boundary conditions is proposed. By using support vector regression (SVR), the stress field of the whole Sejila region is determined and shows reasonable accordance with the measured stress data. The study provides the basis for the prediction and prevention of rockbursts in the Sejila tunnel.

Summary: This paper introduces the idea of variable step-size into the Hybrid Affine Projection Algorithm (H-APA) and proposes two variable step-size algorithms based on H-APA, namely the Variable Step-Size Hybrid Affine Projection Algorithm (VSS-H-APA) and the Modified Variable Step-Size Hybrid Affine Projection Algorithm (MVSS-H-APA). These two variable-step algorithms aim to further improve the robust performance and convergence speed of H-APA under non-Gaussian noise. The MVSS-H-APA goes beyond VSS-H-APA to estimate the noise for better convergence performance. The proposed algorithm performs better than existing algorithms in system identification under symmetric non-Gaussian noise.

Summary: This study demonstrates the selective growth of high-purity gold films onto nanoscale 3D architectures using the Me2Au (acac) precursor and pulsed laser pyrolytic chemical vapor deposition. The high thermal resistance of the nanoscale geometries enables selective deposition. The effects of laser irradiance, pulse width, and precursor pressure on the growth rate were explored, and feature-targeting resolutions of approximately 100 and 5 μm were achieved using diode lasers coupled to multimode (915 nm) and single mode (785 nm) fiber optics, respectively. Finite element thermal modeling was used to rationalize the experimental results.

Summary: A novel hybrid affine projection algorithm (H-APA) is proposed as a derivation of the affine projection sign algorithm (APSA). The proposed algorithm incorporates the robust mixed-norm algorithm (RMNA) to handle impulsive noise. Simulation results demonstrate that the proposed algorithm is robust to impulsive noise and achieves fast convergence under colored input conditions. Additionally, a simplified version of H-APA (SH-APA) is derived to reduce algorithm complexity, and numerical simulations show that the proposed algorithms outperform existing AP-type algorithms in terms of convergence speed.

Summary: 3D nanoprinting using focused electron beam-induced deposition is susceptible to structural distortions caused by temperature gradients. In this study, an electron dose compensation strategy called the Decelerating Beam Exposure Algorithm (DBEA) is proposed to correct for nanowire bending during computer-aided design. The DBEA utilizes an analytical solution derived from 3D nanoprinting simulations to offset undesired heating effects. This compensation strategy has the potential to improve the fidelity of 3D nanoscale printing.
