Implementing Fixed-Point Programming for DSP PR Controllers

Today, we continue our work on fixed-point programming, which is quite significant for using PR control, especially since floating-point microcontrollers are expensive. Previously, in floating-point development, we discussed the discretization and code implementation of the Proportional Resonant Controller (QPR). For fixed-point implementation: Considering quantization errors, we directly run the IIR2 function of the PR controller … Read more

JBC | Dentin Sialophosphoprotein (DSP) Acts as an Angiogenic Factor through Endoglin

Dentin sialophosphoprotein (DSPP) is highly expressed in odontoblasts responsible for dentin formation. Traditionally, DSPP is considered an extracellular matrix protein that regulates the formation and mineralization of dentin matrix. In Dspp knockout mice, in addition to defects in dentin formation, researchers observed a phenotype of reduced angiogenesis in certain regions of the femur. However, the … Read more
