Engineered terahertz emission from spintronic heterostructures: amplitude, phase and chirality
Published 2023“…As such, the photoexcitation leads to ultrafast spin-scattering events in the FM, during which the spins transport from the FM into the adjacent heavy metal(HM) layer to experience an inverse spin Hall effect, producing a transverse charge current and terahertz radiation. …”

Information fusion and cooperative control for target search and localization in multi-agent sensor networks
Published 2013“…A diffusion Kalman filtering algorithm based on the covariance intersection method is proposed, where local estimates are fused by incorporating the covariance information of local Kalman filters. Our algorithm leads to a stable estimate for each agent regardless of whether or not the system is uniformly observable locally with the measurements of itself and its neighbors as long as the system is uniformly observable with the measurements of all agents and the communication is sufficiently fast compared to the sampling. …”

Therapeutic effects of Cosmos caudatus kunth leaf extract in the prevention and treament of obesity in sprague dawley rats
Published 2015“…The extract also increased the fecal excretion of fat in rats (96.9±10.5 - 114.6±9.3 mg/g in preventive study and 87.7±10.0 - 124.6±20.2 mg/g in treatment study) when compared to that of control HFD groups (55.4±6.6 - 58.2±2.6 mg/g) respectively, suggesting that C. caudatus reduces the progression of obesity by inhibiting pancreatic lipase, leading to malabsorption of fat,validating the in-vitro results obtained in first part of the study. …”

Map matching algorithms for intelligent transportation system
Published 2021“…To determine the position of the target vehicle, most of the existing works need a large search space. This inevitably leads to large computational overheads. In addition, the measurement errors of state information can be large due to the external conditions. …”

Clustering-based solutions for energy efficiency, adaptability and resilience in IoT networks
Published 2024“…Owing to their low- cost nature and susceptibility to damage, tampering or battery exhaustion, some devices may become faulty leading to unexpected behavior. IoT networks need to remain functional and resilient even with the presence of such faulty devices. …”
