To achieve very large amplitude oscillations before the dielectric breakdown of the MTJ, a very low critical current density for STT-induced magnetic precessionJSTTis required. In fact, it was shown theoretically thatPoutincreases withJ/JSTT42. The fact that STT excited oscillations are observed in...
Lipoproteins play a key role in regulating plasma and tissue levels of cholesterol. Apolipoprotein B (apoB)-containing lipoproteins, including chylomicrons, very-low density lipoprotein (VLDL) and low-density lipoprotein (LDL), serve as carriers of triglycerides and cholesterol and deliver these metabo...
1. Generating synthetic images from low-density regions on the data manifold 识别数据流形上的低密度区域:给定数据分布q(x),低密度区域或邻域是数据流形中的一部分,其样本密度明显低于其他区域。要设计从这些区域采样的技术,第一步是对它们进行特征描述。扩散模型的基于似然估计的局限性。描述流形密度的自然选择...
The rapid development of information technology has generated substantial data, which urgently requires new storage media and storage methods. DNA, as a storage medium with high density, high durability, and ultra-long storage time characteristics, is pr
The decreased expression of Fasn and two other genes in the liver evoked lower production of low-density lipoprotein cholesterol and triglycerides in the liver as well, according to the study. Mate tea is an herbal beverage rich in phytochemicals, flavonoids and amino acids that is consumed as ...
The serum samples were assayed for TG, TC, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels with an Olympus AU2700 Clinical Chemistry Analyzer (Olympus Inc., Tokyo, Japan). Insulin levels were determined using commercial rat insulin enzyme-linke...

In this article, the amount of monomeric RBD-His immobilized on the chip was comparable and strictly controlled at a low density (100–200 RU). Given that the mobile analyte was dimeric ACE2-hFc, the 2:1 (bivalent analyte) binding model would be more in line with the actual interaction ...
(FACsPbBr3) single crystals at high yield from low-purity (98%) precursors using a solution method. The introduction of formamidinium into CsPbBr3reduces defect density in crystals by eliminating the phase transition upon cooling from growth temperature to room temperature. A mixed solvent is ...
