为了提高基于垂直结构的分层空时结构(V-BLAST, vertical bell-laboratories layered space-time)的多码 CDMA 系统的抗干扰能力与系统容量,文章提出了一种将 MMSE 均衡与 Turbo 译码联合运算进行的方法,得到了一种针对该系统的迭代均衡接收算法。该接收算法包含两个连续的软输入软输出模块,首先经过 MMSE 均衡后得到第一个软输出,然后从 Turbo 译码器得到第二个软输出。每一次迭代过程中,从均衡和译码中得到的外赋信息作为第二次迭代的先验信息。仿真结果表明,文章提出的迭代均衡接收算法相比较传统非迭代接收算法,性能有非常可观的改善。

The fatigue properties of 400 MPa grade supersteel, plain low carbon steel SS400 and microalloyed steel Q340TM were investigated through tensile-compression fatigue experiment with R =- 1. The results indicate that the fatigue limit of the 400 MPa supersteel is higher than that of SS400 steel and close to that of the 340TM steel. According to the analysis of fatigue fracture, the fatigue striations of supersteel SS400 is thinner than that of SS400 steel and 340TM steel, and grain refinement can increase the fatigue limit.

Traditional glucose-lowering chemical agents, including various types of insulin and insulin secretagogues, insulin sensitizers, gliptins, etc., are based on diabetic pathogenesis of insulin resistance(IR) and islet insufficiency. Numerous evidence-based medical studies have shown that these traditional hypoglycemic chemical agents do not provide cardiovascular benefit to patients with type 2 diabetes mellitus(T2 DM) and may even increase the risk of all-cause mortality. Based on research evidence published to date, these studies show that overload of energy could increase the incidence and prevalence of T2 DM, and reduction in the heat load can significantly reduce the incidence of T2 DM. Therefore, the essence of T2 DM is heat overload, meaning heat overload is the etiology of obese T2 DM. At the same time, results of numerous studies show that heat overloading is the cause of IR. IR and islet dysfunction are protective factors in intervening with heat *** drugs, which are based on the mechanisms of IR and islet insufficiency, increase caloric reserve and cause or worsen obesity, which is equivalent to exacerbating the basic etiology and the cardiovascular risk factor of T2 DM. Thus, a reasonable strategy for prevention and treatment of obese T2 DM appears to promote the negative balance of calories and the elimination of caloric reserves. Chinese herbal medicines can promote negative balance of heat in many aspects, which can bring new hope for prevention and treatment of T2 DM.

We present an efficient spherical parameterization approach aimed at simultaneously reducing area and angle dis-tortions. We generate the final spherical mapping by independently establishing two hemisphere parameterizations. The essence of the approach is to reduce spherical parameterization to a planar problem using symmetry analysis of 3D meshes. Experiments and comparisons were undertaken with various non-trivial 3D models, which revealed that our approach is efficient and robust. In particular, our method produces almost isometric parameterizations for the objects close to the sphere.
