在研究、整理各地手语的基础上,形成能在全国范围使用的通用手语,一直是我国语言文字工作的一项基本政策和重要组成部分。作为手语技能与法律文化的融合产物,法律手语不仅是聋人群体传递法律信息的语言工具,更承载着向聋人群体进行法学知识教育的重要功能。文章从法律手语的内在特征出发,探究法律手语的规范路径与应用模式,既是新时期学科手语研究工作的内在要求,也是聋人群体基本公共法律服务权益保障的客观需要。

Locally repairable codes（LRCs） were proposed to reduce the repair degree in distributed storage systems. In particular, LRCs with availability are highly desirable for distributed storage systems, since this kind of codes provide the mechanism of local repair for code symbols and parallel reading of hot *** this paper, we propose four types of（n, k, r, t）;LRCs from combinatorial designs. We introduce several constructions of LRCs with strict availability and some constructions of distance-optimal LRCs with information-symbol locality. Most of our constructions in this paper are over F;, i.e., they are suitable for implementation.

为明确骨桥蛋白(OPN)和多房棘球蚴(Echinococcus multilocularis,Em)p38丝裂原活化蛋白激酶(p38MAPK)信号通路在Em发育过程的作用,剖检感染Em 4~6月的长爪沙鼠,提取Em原头节后,分别用不同浓度的p38MAPK抑制剂(SB202190)处理Em原头节,选取合适的SB202190浓度后在体外将原头节分为DMSO组、anti-p38MAPK组、PBS组、OPN组、OPN+anti-p38MAPK组,采用伊红染色、caspase-3试剂盒检测caspase-3、EDU和Hoechst染色、活性氧(ROS)检测探针检测原头节的活性、凋亡和增殖情况。结果显示,抑制Em的SB202190适宜浓度为20μmol/L,SB202190增加Em的伊红染色率、caspase-3水平,减少EDU阳性、ROS水平,OPN可减少Em伊红染色率、caspase-3水平,增加EDU阳性率、ROS水平,且SB202190可逆转OPN对Em的结果,这些结果表明SB202190可抑制Em的活性和增殖、促进凋亡并与浓度正相关,而OPN可促进Em的活性和增殖、抑制凋亡,且SB202190可逆转OPN对Em的作用。研究结果为OPN和p38MAPK信号通路可能成为治疗多房棘球蚴病的新分子靶点提供证据。

Age estimation plays an important role in human-computer interaction *** lack of large number of facial images with definite age label makes age estimation al-gorithms *** label distribution learning(DLDL)which employs convolutional neural networks(CNN)and label distribution learning to learn ambiguity from ground-truth age and adjacent ages,has been proven to outperform current state-of-the-art ***,DLDL assumes a rough label distribution which covers all ages for any given age *** this paper,a more practical label distribution paradigm is proposed:we limit age label distribution that only covers a reasonable number of neighboring *** addition,we explore different label distributions to improve the performance of the proposed learning *** employ CNN and the improved label distribution learning to estimate *** results show that compared to the DLDL,our method is more effective for facial age recognition.

nc-Ti C/a-C：H nanocomposite films were prepared by filtered cathodic arc technique. The influence of C_2H_2/Ar flow ratio on the composition, structure, and mechanical properties of films was investigated by X-ray photoelectron spectroscopy（XPS）, X-ray diffraction（XRD）, Fourier transform infrared spectroscopy（FTIR）,Raman spectroscopy, nanoindentation, and ball-on-disc tribometry. The films show a nanocomposite structure in which Ti C crystallites are embedded in the amorphous matrix of a-C：H phase. C content in films increases with the flow ratio of C_2H_2/Ar, simultaneously, the crystallite size of TiC decreases. Contrary to the nc-Ti C/a-C：H films deposited by magnetron sputtering in which the sp3 C content increases with C_2H_2 flow rate, the increase of C_2H_2 flow rate leads to the increase of sp2 C content in films deposited by filtered cathodic arc technique. The nc-Ti C/a-C：H films deposited by cathodic arc technique have a pronounced hardness maximum of 30 GPa under the C_2H_2/Ar flow ratio of 12. Tribological performance of films is controlled by the sp2 content in films. Higher sp2 content promotes the formation of graphite-like transfer layer during sliding,and results in lower wear rate and friction coefficient.
