The sensor employs a thin metal-dielectric interface integrated atop an all-dielectric photonic crystal, enabling two ultra-narrowband resonances under normal incidence without the use of coupling prisms or gratings. Numerical modeling using the transfer matrix method (TMM) confirms strong field confinement at the metal-sample interface, resulting in high spectral selectivity and dual resonance modes with full width at half maximum (FWHM) values of 0.133 nm and 0.143 nm. The corresponding quality factors (<em>Q</em>) reach 4029 and 3778, and figures of merit (FoM) are 90 RIU⁻¹ and 106 RIU⁻¹, respectively. The device exhibits sensitivities of 12 nm/RIU and 15.1 nm/RIU for a refractive index variation of Δ<em>n</em>_<em>S</em> = 0.01. For biological testing with A549 lung cells, resonance shifts of 0.20 nm and 0.23 nm are observed between healthy (<em>n</em> = 1.3662) and cancerous (<em>n</em> = 1.3568) samples. Considering a spectrometer resolution of 0.1 nm, the minimum detectable refractive index changes are 8.3 × 10⁻³ RIU and 6.6 × 10⁻³ RIU for the two resonances. Due to its ultra‑narrow linewidth, high FoM, label‑free operation, and compatibility with standard thin‑film fabrication, the proposed TPP‑based biosensor offers a compact and accurate platform for real‑time optical cancer diagnostics.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"347 ","pages":"Article 172642"},"PeriodicalIF":3.1,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145842307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing methods often face challenges, including low embedding capacity, high communication overhead, security vulnerabilities, and overflow/underflow. Addressing these limitations, this paper proposes an efficient separable RDH in Encrypted Images (RDH-EI) method based on a contingent bit-pair. Embedding data at the contingent bit-pair level enhances the embedding capacity and fortifies the security and privacy of both the user message and the plain cover. The embedding process modifies the Most Significant Bits (MSBs) of interpolated pixels according to the proposed bit-pair rule set. Each encrypted cover byte can contribute up to seven bits for data embedding, enabling greater data concealment. At the receiving end, the extraction process recovers the embedded message by reconstructing it using the XOR operation and the plain cover by reversing the encryption, requiring no overhead for recovery. The proposed method is evaluated against state-of-the-art techniques, and results demonstrate significant enhancements in embedding capacity. It achieves a maximum embedding capacity of 455,175 bits at a bit rate of 1.7432 bpp, utilizing minimal execution time over BOWS2, USC-SIPI, and Kodak datasets, low distortion, and perfect reversibility, making it suitable for secure data transmission.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"347 ","pages":"Article 172645"},"PeriodicalIF":3.1,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145885498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distributed Denial of Service (DDoS) attacks hijack many distributed devices to overwhelm systems, making them a persistent cybersecurity concern. Although there are various detection methods already, the growing complexity and frequency of these threats demand more resilient and adaptive security solutions. Existing detection methods frequently fall short in effectively handling the dynamic nature of cloud environments. These limitations collectively motivate the development of more robust and integrated approaches. As a result, this study presents a new architecture for detecting DDoS attacks in virtual cloud computing systems using the Adaptive Hybrid Learning (AHyL) approach. Initially, datasets are collected from publicly available standard sources. Then, the gathered data undergoes data preprocessing to improve its quality. Subsequently, a Spatial Cross-Attention-based Fuzzy Autoencoder (SCA-FAE) is employed to extract robust features. The combination of Spatial Cross-Attention (SCA) and Fuzzy Autoencoder (FAE) in the SCA-FAE approach offers the distinctive advantage by leveraging spatial correlations and handling data uncertainty. These extracted features are forwarded to the AHyL model for the detection process. This offers the distinctive advantage of integrating an Extreme Learning Machine (ELM) with a Residual Recurrent Neural Network (Res-RNN) to balance high-speed processing. Prediction performance is further enhanced by optimizing the model’s parameters using the Random Number Updated Hippopotamus Optimization (RNU-HO) algorithm. Finally, a comparative evaluation shows that the proposed technique significantly outperforms traditional approaches.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"346 ","pages":"Article 172641"},"PeriodicalIF":3.1,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145786603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interaction between the magnetization of the medium and the magnetic field component of the EM wave is studied by solving Maxwell’s equations coupled with the Landau-Lifshitz (L-L) equation, which governs the magnetization dynamics. The resulting nonlinear magnetization behavior is described by a generalized derivative nonlinear Schrödinger (DNLS) equation, selected for its ability to capture complex spin interactions and electromagnetically induced nonlinear effects that are inadequately represented in conventional integrable models. To investigate the nonlinear spin excitations, we perform numerical simulations by solving the generalized DNLS equation using the Method of Lines, implemented in Mathematica software. This approach enables the identification of nonlinear spin excitations in the form of damped and amplitude-modulated one-soliton structures and phase-sensitive two-soliton collisions. Despite energy dissipation, the interactions retain spatial coherence, demonstrating the robustness of solitonic behavior under dispersive and nonlinear perturbations. Dispersion plays a critical role in modulating collision timing and shaping the post-interaction profiles.

Modulation instability analysis highlights the role of nearest-neighbor coupling in altering the intensity and bandwidth of these solitons.
