论《沧浪诗话》的“师古”思想体系及其得失

本文从师法的对象——“以汉魏晋盛唐为师”、师法的原因——“盛唐诸人惟在兴趣”和师法的方法——从“识”到“妙悟”三个角度对严羽《沧浪诗话》“师古”思想体系进行了梳理和阐发,并对之作出了准确的特点、原创的意义和超越性的价值等正面评价以及矛盾、错讹和疏漏的负面评价。     

Mutations in LMF1 cause combined lipase deficiency and severe hypertriglyceridemia

Hypertriglyceridemia is a hallmark of many disorders, including metabolic syndrome, diabetes, atherosclerosis and obesity. A well-known cause is the deficiency of lipoprotein lipase (LPL), a key enzyme in plasma triglyceride hydrolysis. Mice carrying the combined lipase deficiency (cld) mutation show severe hypertriglyceridemia owing to a decrease in the activity of LPL and a related enzyme, hepatic lipase (HL), caused by impaired maturation of nascent LPL and hepatic lipase polypeptides in the endoplasmic reticulum (ER). Here we identify the gene containing the cld mutation as Tmem112 and rename it Lmf1 (Lipase maturation factor 1). Lmf1 encodes a transmembrane protein with an evolutionarily conserved domain of unknown function that localizes to the ER. A human subject homozygous for a deleterious mutation in LMF1 also shows combined lipase deficiency with concomitant hypertriglyceridemia and associated disorders. Thus, through its profound effect on lipase activity, LMF1 emerges as an important candidate gene in hypertriglyceridemia.

Mechanical Properties of Laterally Driven Microresonance with a One-Side Straight-Leg Suspension

The mechanical properties of lateral polysilicon comb-driven microresonators suspended from one-side straight-leg beams, which are widely used in linear microvibromotors, are investigated in this paper.The lateral vibration of the microresonator was modeled assuming that the symmetry of the microstructures and the applied loads are different. Methods were given to calculate the stress, lateral displacement, spring coefficient, and resonant frequency. The results show that the simple mechanical model is a superfluous system with three unknown variables. The results differ from pervious results for a microresonator suspended from double-side straight-leg beams, which has been commonly used to design linear microvibromotors.
