In recent years, many efforts have been made to develop advanced metal oxide semiconductor nanomaterials with exotic magnetic properties for modern applications w.r.t traditional analogues. Dilute oxides (DMSOs) are promising candidates superior control over the charge and spin degrees of freedom. DMSOs transparent, wide band gap materials induced ferromagnetism in doping, a minor percentage 3d cation create long-range antiferromagnetic order. Although significant carried out achieve DMSO...
The study examines the relationship between political behaviors, e.g., ingratiation, structure change, cooptation, and threat, their outcomes such as interpersonal trust, alienation, feeling about job performance. A negative behaviors trust andfeelings performance, a positive alienation is hypothesized. Results largely support hypotheses. However, feelings performance marginal. Findings are discussed in light of available research.
This research has used the techniques of Natural Language Processing to explore how do sentiment analysis on social media by using three algorithms, G-LSTM, RMDEASD, and BERT. It tested models perform a different set domains like disaster management, corporate performance, consumer behavior for purpose classification. The study utilized more than 500,000 posts as dataset, with accuracy rates 88.4% 85.7% 91.2% Results reveal that BERT surpassed other in terms contextual understanding...
MicroRNAs (miRNAs) are small, non-coding molecules that act as essential post-transcriptional regulators in various biological processes. Many studies suggest miRNAs may modulate the host immune response during virus infections. We analyzed publicly available transcriptomics data involving infection with different RNA viruses and identified most prominent candidate, miR-203a-3p. This miRNA is upregulated H7N9, HCV, DENV2 Interestingly, pathway analysis of microRNA-targeted genes shows...
We analyse the locking phenomena arising when an external-cavity diode laser is subjected to optical injection from another uncontrolled laser. The system stability investigated as a function of coupled cavity time delay and strength. Different regimes, spanning 'in-phase locking' 'out-of-phase with ultimate amplitude death low-frequency fluctuations/pulsations, are described experimentally well numerically for weak moderate injection. Qualitative agreements between observed results...
In an attempt to identify novel magnetic refrigerant materials, we have studied the and magnetocaloric properties in RNi compounds with R = Gd, Ho Er. GdNi is a simple ferromagnet collinear structure contrast HoNi ErNi, which moments of rare earth sublattice are arranged non-collinearly. The ordering temperatures observed be 69 K, 36.5 K 10 K for GdNi, respectively. maximum values effect found 17 J kg−1 K−1, 15 J kg−1 K−1 29 J kg−1 K−1 Er, respectively, applied field 50 kOe. relative cooling...
