( Chao Ran Chen ),( Chu Ren Huang ),( Kathleen Ahrens ) 한국언어정보학회 1995 국제 워크샵 Vol.1995 No.-

The role that constructions play in a linguistic theory has changed throughout the evolution of generative theories. Construction specific rules are common when transformations are envisioned as tree to tree operations in classical TG. On the other extreme, constructions, as well as all structural properties, are regarded as derived linguistic properties predictable from various principles in recent GB theories. Since whether a construction is an autonomous linguistic entity or not has great implications for either a formal or a computational linguistic theory, we will examine the status of Mandarin existential construction based on the theory of Construction Grammar [1,2]. We will show that the Mandarin existential construction represents all unique structure-meaning pair that cannot be captured in a grammar unless the pairing is regarded as a theoretical entity in linguistics ([3]). Since constructions are shown to exist in Mandarin Chinese, we support the theoretical claims of Construction Grammar as well as the position that constructions must be taken into account in NLP.

In the present work, graphite grains of different sizes were added into the electrolyte to prepare ceramic coatings on aluminum by plasma electrolytic oxidation (PEO). Scanning electron microscopy (SEM) coupled with an energy dispersive X-ray analysis system (EDX), Raman spectroscopy and X-ray diffractometer (XRD) were used to characterize the coatings. A three-electrode system was used to evaluate the corrosion performances of the coatings in a 3.5 wt.% NaCl solution. It was found that the morphology and corrosion performance of the coatings were significantly influenced by the size of the graphite grains. Compared with bigger graphite grains, finer ones were involved in the oxidation process and embedded within the ceramic coatings, which made the coatings less porous and more compact. Thus, the corrosion resistance of the coatings with embedded graphite grains was greatly improved.

Lattice structures with excellent mechanical performance can be achieved through delicate design. In this work, inspired bythe soft–hard multiphase crystals, three types of dual phase lattice structures (DPLS) composed of body-centered cubic withZ-struts (BCCZ) matrix phase and face and body-centered cubic with Z-struts (FBCCZ) reinforcement phase were designedand fabricated by selective laser melting (SLM) using 316L stainless steel powder. Quasi-static compression experimentand numerical simulation were carried out to investigate their mechanical properties, energy absorption and deformationbehavior. The results showed that the mechanical properties of all DPLS samples were higher than that of single phaseBCCZ lattice structure. The four-body diagonal DPLS sample exhibited the highest specific strength and specific stiffness,which was 9.0% and 14.2% higher than single phase BCCZ lattice structure; while, the two-face diagonal DPLS sample hadthe highest specific energy absorption value of 17.45 J/g. Besides, the experimental and simulated results revealed that thearrangements and volume fraction of reinforcement phase had a significant impact on the performance, deformation behaviorand internal stress distribution of the DPLS samples during compressive deformation.

Understanding the tritium release and retention behavior of candidate tritium breeder materials is crucial for breeder blanket design. Recently, a melt spraying process was developed to prepare Li4SiO4 pebbles, which were subsequently subjected to the in-pile tritium production and extraction platform in China Mianyang Research Reactor (CMRR) to investigate their in-situ tritium release behavior and irradiation performance. The results demonstrate that HT is the main tritium release form, and adding hydrogen to the purge gas reduces tritium retention while increasing the HT percent in the purge gas. Post-irradiation experiments reveal that the irradiated pebbles darken in color and their grains swell, but the mechanical properties remain largely unchanged. It is concluded that the tritium residence time of Li4SiO4 made by melt spraying method at 467 ◦C is approximately 23.34 h. High-density Li4SiO4 pebbles exhibit tritium release at relatively low temperatures (<600 ◦C) that is mainly controlled by bulk diffusion. The diffusion coefficient at 525 ◦C and 550 ◦C is 1.19 × 10 11 cm2/s and 5.34 × 10 11 cm2/s, respectively, with corresponding tritium residence times of 21.3 hours and 4.7 hours.

Comorbidity Relationship to Outcome of Radical Cystectomy in Chinese: a Single Institution Study with the ACE-27 Comorbidity Index

Xuan, Zhu,Zhong, Zhao-Hui,Zhang, Xuan-Zhi,Zhang, Lei,Zhao, Xiao-Kun,Lv, Chen,Xu, Ran,Ren, Wei-Gang,Li, Song-Chao Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.3

To determine the relationship between comorbidity and outcome after radical cystectomy in Chinese patients by using the Adult Comorbidity Evaluation (ACE)-27 index. Two-hundred-and-forty-six patients treated with radical cystectomy at the Second Xiangya Hospital of Central South University, Hunan Province, China between 2000 and 2010 were retrospectively analyzed. Medical records were reviewed for age, gender, delayed time of radical cystectomy, urinary diversion type, pelvic lymphadenectomy status, TNM stage, and pathological grade. Comorbidity information was assessed by the ACE-27 index. The outcome measurement was overall survival. Univariate and multivariate Cox proportional hazards regression analyses were used to determine the association between comorbidity and outcome. The study population consisted of 215 (87.40%) males and 31 (12.60%) females with a mean age of $62{\pm}11$ years. Median duration of follow-up was $47{\pm}31$ months. A total of 151 (61.38%) patents died during follow-up. Of those, 118 (47.97%) had at least one comorbidity. According to the ACE-27 scores, 128 (52.03%) patients had no comorbidity, 79 (32.11%) had mild, 33 (13.41%) had moderate, and 6 (2.45%) had severe comorbidities. Multivariate analysis indicated that moderate (p=0.002) and severe (p<0.001) comorbidity was significantly associated with decreased overall survival. In addition, age ${\geq}70$ years (p=0.002), delayed time of radical cystectomy >12 weeks (p=0.044), pelvic lymphadenectomy status (p=0.014), and TNM stage >T3 (p<0.001) were determined to be independent risk factors of overall survival. Increasing severity of comorbidity statistically correlated with decreased overall survival after radical cystectomy.
