A Versatile Cell of Multimode First‐Order Universal Filter Using VCIIs

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
This article presents a new generic core cell for designing the first‐order universal filter employed second‐generation voltage conveyor (VCII+). With appropriate admittance selection, the proposed core cell can derive four different filter types, namely, low‐pass, high‐pass, inverting all‐pass, and noninverting all‐pass functions and encompassing four

In vitro digestibility and solubility of phosphorus of three plant‐based meat analogues

Journal of Animal Physiology and Animal Nutrition, Volume 108, Issue S1, Page 24-35, May 2024.
Abstract Interest in plant‐based meat analogues has increased and can be expected to be applied to pet foods, which necessitates the understanding of the nutrient supply in those foods. Our primary aim was to advance our understanding of the digestive properties of sterilized plant‐based meat analogues. The impact of the preparatory processing steps on
