Herein, a systematic mechanism behind long‐range ferromagnetic (FM) ground state is described based on 4 d –4 f interactions demonstrated in strongly correlated Ba 2 DyRuO 6 and TmRuO double‐perovskite (DP) systems. Density functional theory (DFT) + U possible half‐metallic FM nature of the considered DPs realized along with integer values spin magnetic moments (8.0 3.0 μ B f.u. −1 , respectively). This robust configuration mainly dependent Ru 5+ rare‐earth (RE 3+ ) elements highlighting...
Abstract In the present study, ferromagnetic semiconductor behavior of Mn doped BaTe is reported along with their physical properties. The calculations are done by full potential linearized augmented plane wave (FP-LAPW) approach within spin-polarized density functional theory (SP-DFT). Formation energies were computed to satisfy stability alloys. spin-polarization included in study electronic (band structure (BS), states (DOS)) and magnetic characteristics. Ba 1−x x Te elucidates nature...

Besides its positive uses, it also popular among cybercriminals illegal activities such as trafficking, smuggling, betting, and illicit trade. There a need Browser forensics to identify use in unlawful explore consequences. This research analyzes artifacts generated by on Windows-based systems. methodology integrates forensic techniques into incident responses per NIST SP (800-86), exploring areas...
The growing prevalence of AI-generated multimedia content, particularly deepfakes, has facilitated the spread fake news, propaganda, identity theft, and undermined importance privacy authenticity in digital media. Existing techniques often lack robustness handling complex deepfake artifacts, especially those involving fused facial regions such as eyes, nose, mouth. This study addresses challenges posed by deepfakes across domains social media, politics, entertainment proposing a hybrid deep...
This research focuses on the detection of deepfake images and videos for forensic analysis using deep learning techniques. It highlights importance preserving privacy authenticity in digital media. The background study emphasizes growing threat deepfakes, which pose significant challenges various domains, including social media, politics, entertainment. Current methodologies primarily rely visual features that are specific to dataset fail generalize well across varying manipulation However,...
Nanomaterials, due to their large aspect-to-size ratio and reactive surfaces that facilitate access through biological barriers, can induce oxidative stress in host cells. Therefore, there is a growing concern about the risks of nanomaterials. This study investigated effects copper (1.5 mg/L) as CuO or nanoparticles (Cu-NPs) common carp Cyprinus carpio along with beneficial Myristiga fragrans seed extract (MFSE) administrated post-treatment at different doses (4 8 12 for 28 days. The MFSE...

Abstract Barium based double perovskite rhenates are being comprehensively studied due to their diverse magnetic behaviors, extending from ferri- (anti) ferro-magnetism which is mostly influenced by theoretical Hubbard interaction parameter (U). Therefore, density functional theory (DFT) and U brought together reveal the origin of half metallicity with ferromagnetic ordering in Ba 2 CdReO 6 ferrimagnetism ErReO . The precise estimation exchange correlation energies has been performed...
