Short-Term Wind Power Interval Forecasting Based on Hybrid Modal Decomposition and Improved Optimization.

Accurate wind power prediction can effectively alleviate the pressure of the power system peak frequency regulation, and is more conducive to the economic dispatch of the power system. To enhance wind power forecasting accuracy, a hybrid approach for wind power interval prediction is proposes in this study. Firstly, an Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (ICEEMDAN) is applied to decompose the initial wind power sequence into multiple modes, and Variational Mode Decomposition is used to further decompose the high-frequency non-stationary components.

Angiotensin II stimulates phosphorylation of 4E-binding protein 1 and p70 S6 kinase in cultured vascular smooth muscle cells.

Aim: To examine the regulatory effects of angiotensin II (Ang II) on the phosphorylation of 4E-binding protein 1 (4E-BP1) and p70 S6 kinase in cultured vascular smooth muscle cells (VSMC), and the contribution of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB) signaling pathway in this process.

Methods: VSMC obtained from rat thoracic aortas were cultured. The phosphorylation of 4E-BP1 and p70 S6 kinase was detected by immunoblotting.

Persistence of MHC DR nonexpression on swine cells by introduction of a mutated MHC class II transactivator gene: a comparison with the effect induced by antisense RNA.

CIITA (class II transactivator) is a coactivator essential for transcription of MHC class II genes. In this study, a construct with a mutated CIITA gene with N-terminal domains depleted was constructed. This mutated CIITA (mCIITA) was able to repress DR and DQ expression in 45.

[The relationship between insulin resistance and postprandial abnormal serum triglyceride metabolism in essential hypertension].

Objective: To investigate the relationship between insulin resistance (IR) and postprandial abnormal metabolism of serum triglyceride-rich lipoprotein in essential hypertension (EH).

Methods: In 44 patients with EH and 22 normal subjects (NS). Total cholesterol, HDL cholesterol, LDL cholesterol, apoliprotein AI and apoliprotein B in fasting serum and serum triglyceride before and 2, 4, 6, 8 hours after a standardized fat loading were measured.
