The ash weevil, Myllocerus subfasciatus, is a significant insect pest that infests brinjal. Both the adults and grubs feed on the leaves and roots, respectively, leading to considerable yield loss. The subterranean habits of the larvae limit the effectiveness of insecticide applications, necessitating the implementation of integrated pest management programs that utilize entomopathogenic fungi.

- Wearable sensors like Seismocardiography (SCG) offer non-invasive cardiac health monitoring, but challenges from motion artefacts, primarily caused by walking, limit their effectiveness.
- The Adaptive Bidirectional Filtering (ABF) technique improves SCG signal quality by using advanced noise-cancellation and a unique filtering process that distinguishes between actual heart signals and motion noise.
- Empirical tests show ABF achieves high accuracy in heart rate estimation (r-squared value of 0.95 at -20 dB SNR) and effectively reduces motion artefacts without needing ECG inputs, making it suitable for use in noisy settings.
Bio-inspired zinc oxide nanoparticles are gaining immense interest due to their safety, low cost, biocompatibility, and broad biological properties. In recent years, much research has been focused on plant-based nanoparticles, mainly for their eco-friendly, facile, and non-toxic character. Hence, the current study emphasized a bottom-up synthesis of zinc oxide nanoparticles (ZnO NPs) from Psidium guajava aqueous leaf extract and evaluation of its biological properties.
