Two-dimensional orthogonal matching pursuit (2D-OMP) algorithm is an extension of the one-dimensional OMP (1D-OMP), whose complexity and memory usage are lower than the 1D-OMP when they are applied to 2D sparse signal recovery. However, the major shortcoming of the 2D-OMP still resides in long computing time. To overcome this disadvantage, we develop a(More)
The M-ary source with nonstationary correlation can be encoded with a single binary low-density parity-check (LDPC) code and decoded together in distributed source coding. The joint-bitplane belief propagation (JBBP) is a useful decoding algorithm for multiple bitplanes of an M-ary source. However, it suffers from the drawbacks of low computational(More)
Soybean polypeptide TTYY has substantial antioxidant activity. The present study aimed to investigate the mechanisms of the potential ability of TTYY to allow rats to recover from oxidative damage using 1H-NMR-based metabonomics. Male Wistar rats received injections of d-galactose to establish the oxidative damage model, then gavaged with TTYY. After(More)
Tongluo Xingnao Effervescent Tablet (TXET), a traditional Chinese herbal formula composed of Ligusticum chuanxiong hor, Scutellaria baicalensis Georgi and Angelica sinensis, has been widely used to treat Alzheimer's disease (AD) and related dementias for decades in China. In the present study, we investigated the effects of TXET on mitochondrial function,(More)
OBJECTIVE To study the effect of Tongluo Xingnao effervescent tablet on learning and memory of dementia rats induced by injection of Abeta25-35 in hippocampus and expression of insulin-degrading enzyme in hippocampus, in order to provide basis for preventing and treating senile dementia. METHOD The dementia rat model was established by injecting(More)
