Improvement of ECG Signal Noise Removal Using Recursive Kalman Filter [PDF]
Nowadays, Kalman filter has been wildly used for solving the problem of real world. Kalman filter is a recursive filter that estimates the state of a linear dynamic system from a series of noisy measurements.

Tutorial: Digital filtering and processing of signals [PDF]
Behav. Res. Meth. & Instru., 1973, Vol. 5 (2) Digi tal filtering was described as a general mathematical technique of processing sequences of sampled data points analogous to the action of electrical or mechanical filtering. The discussion often referred to filtering as taking place in the time dimension, although it was noted that it could take place ...

The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

On the Fractionalization of the Shift Operator on Graphs
The theory of graph signal processing has been established with the purpose of generalizing tools from classical digital signal processing to the cases where the signal domain can be modeled by an arbitrary graph.

UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

A Coordinate System Choice when Information Signal Processing by Kalman Filter
The article describes information signal smoothing problems in the technical systems with movable platform. In such technical systems different coordinate system are used and there is a signal conditioning from one coordinate system into one another when

To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Parallel wideband digital up-conversion architecture with efficiency
Owing to the limited processing speed of current digital signal processing devices, digital generated signal frequency and bandwidth based on digital up-conversion technique has long been a bottleneck.
