本文给出了两种稳定性矩阵的若干等价命题。得到了这两种稳定性矩阵类是亚正定阵类的某种相似扩张类。讨论了这三种矩阵类的各自扩张是否是饱和的问题。     

“N的V”短语的语义结构

“N的V”短语是比较特殊的一种定心短语,其语义结构具有双重性,分显层和隐层两个层面。“N的V”短语的显层语义结构是名核结构,这是考虑到“N的V”的定心句法结构形式对语义结构的制约作用和中心语V已经名物化这两个原因而确定的,可分为领属关系和限制关系两类。“N的V”短语的隐层语义结构是动核结构,这是考虑到N与V之间的确还保留有施事、受事与动核的语义联系以及“N的V”短语是由上文中的主谓句转化来的这两个原因而确定的,可分为施动关系、准施动关系、受动关系、成动关系、使动关系、系动关系、状动关系等7类。

Polymorphisms within the COL5A1 gene and regulators of the extracellular matrix modify the risk of Achilles tendon pathology in a British case-control study

Several genetic loci have been associated with risk of Achilles tendon pathology (ATP) within South African and Australian populations. The aim of this study was, therefore, to evaluate eight previously implicated genetic variants in an independent British population. A total of 130 asymptomatic controls (CON) and 112 participants clinically diagnosed with ATP comprising 87 individuals with chronic Achilles tendinopathy (TEN) and 25 with Achilles tendon ruptures (RUP) were included. All participants were genotyped for variants within the COL5A1, MIR608, IL-1β, IL-6 and CASP8 genes. Primary findings implicated COL5A1 and CASP8. Three inferred allele combinations constructed from COL5A1 rs12722, rs3196378 and rs71746744 were identified as risk modifiers. The T–C–D combination was associated with increased risk of ATP (P = 0.023) and RUP (P < 0.001), the C–A–I combination was associated with increased risk of ATP (P = 0.011), TEN (P = 0.011) and RUP (P = 0.011) and the C–C–D combination was associated with decreased risk of ATP (P = 0.011) and RUP (P = 0.004). The CASP8 rs3834129 DD genotype was associated with decreased risk of TEN (P = 0.020, odds ratio: 0.45, 95% confidence interval: 0.22–0.90) and the CASP8 I–G (rs3834129–rs1045485) inferred allele combination was associated with increased risk of TEN (P = 0.031). This study further highlights the importance of polymorphisms within COL5A1 and CASP8 in the aetiology of ATP.     

类耗散系统的特性

介绍由保面积映像不连续、不可逆耦合构成的"类耗散系统",并以两个系统为例介绍类耗散系统的主要性质.这样的系统中会出现规则或混沌的,能把外部的迭代吸引过来的"类吸引子",但迭代一旦到达类吸引子,又会展示典型的保守性运动.这类系统中可能出现"类V形阵发",在适当的参数改变时,还可以展示从典型的保守系统向近似于耗散系统的连续转变.更多的特异性质还有待于继续研究.     

Biomechanical comparison of the double-push technique and the conventional skate skiing technique in cross-country sprint skiing

Abstract

The aims of the study were to: (1) adapt the “double-push” technique from inline skating to cross-country skiing; (2) compare this new skiing technique with the conventional skate skiing cross-country technique; and (3) test the hypothesis that the double-push technique improves skiing speed in a short sprint. 13 elite skiers performed maximum-speed sprints over 100 m using the double-push skate skiing technique and using the conventional “V2” skate skiing technique. Pole and plantar forces, knee angle, cycle characteristics, and electromyography of nine lower body muscles were analysed. We found that the double-push technique could be successfully transferred to cross-country skiing, and that this new technique is faster than the conventional skate skiing technique. The double-push technique was 2.9 ± 2.2% faster (P < 0.001), which corresponds to a time advantage of 0.41 ± 0.31 s over 100 m. The double-push technique had a longer cycle length and a lower cycle rate, and it was characterized by higher muscle activity, higher knee extension amplitudes and velocities, and higher peak foot forces, especially in the first phase of the push-off. Also, the foot was more loaded laterally in the double-push technique than in the conventional skate skiing technique.
