[[alternative]]Syntactic and Semantic Change of Yiwei
No full text[[abstract]]This is a tentative analysis of the syntactic and semantic change of yiwei. The proto-form of yiwei is proposed to be derived from the adjacent form of yi and ivei, which is semantically comprehended as yi-X-zuo-Y, and contains meanings of both renwei 'regard it as' and dangzuo 'take it as'. The syntactic form of yi-X-wei-Y might result from analogical leveling on the syntactic structure, and hence generates two dichotomies because of the division of labor in meanings and patterns. The first dichotomy occurs when a nominal object corresponds to the meaning of dangzuo 'take it as', and a clausal object corresponds to renwei 'regard it as' , which in turn contains the meaning that speakers report the cognitive content of the cognizer, and the meaning that speakers regard the content as not being correct. The second dichotomy involves on the meaning of renwei 'regard it as'. When being followed by a clausal object in a declarative sentence, yiwei refers to 'wrongly regard it as'. However, when preceding a clausal object in an interrogative sentence, it means 'regard it as'. This analysis can be applied systematically to the change of yiwei in Old Chinese and Modern Chinese. It conforms to the principles of economy and plausibility.[[fileno]]JA01_2005_p3
Effect of polymer fibers on pore pressure development and explosive spalling of ultra-high performance concrete at elevated temperature
No full textThis paper investigated pore pressure development of ultra-high performance concrete (UHPC) included various polymer fibers, i.e., linear low-density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMWPE), polypropylene (PP), polyester (PET), and polyamide (PA) fibers. Temperature and pore pressure were measured simultaneously at different depths of UHPC specimens subjected to one-dimensional heating. It was found that the PP and PA fibers prevented spalling of UHPC by enhancing moisture migration, which resulted in the development of pore pressure in the deeper region of the specimens. The moisture migration in UHPC with LLDPE fibers caused spalling of a layer of concrete in a deep region of specimen. UHMWPE fibers did not affect pore pressure development and spalling resistance of UHPC significantly, while with PET fibers, the pore pressure of UHPC raised sharply due to inadequate moisture migration, leading to spalling of a whole layer. Instead of melting polymer fibers and empty channels left, microcracks created by the fibers were responsible for releasing vapor pressure and spalling prevention. Fibers with high thermal expansion between 100 and 200 °C are recommended for spalling prevention of UHPC

Dialoguing with the World: Xue Yiwei and His Traveling with Marco Polo
No full textThis essay introduces the author Xue Yiwei and his Traveling with Marco Polo, a creative collection that dialogues with Invisible Cities by the postmodern Italian writer Italo Calvino. While Calvino imagines a young Marco Polo describing the fantastic sights of fifty-five cities to an aging Kublai Khan, Xue Yiwei joins the conversation and provides a meticulous explication of each one of Calvino’s cities. Furthermore, Traveling with Marco Polo expands the imaginary cityscapes to include oblique commentaries on the past, present, and future of China as well as the profound meditation on the city as a microcosm of our world. The result is a daring literary experiment that is representative of Xue’s oeuvre overall: at once giving a powerful literary representation of modern Chinese history while engaging in dialogue with writers from all over the world
Odd chain fatty acids are not robust biomarkers for dietary intake of fiber
No full textThe aim of this study is to validate whether OCFAs (Odd chain fatty acids), specifically, pentadecanoic acid (C15:0) and heptadecanoic acid (C17:0) are potential biomarkers of fermentable fiber in two independent studies using a validated analytical method by Zhao et al (Zhao et al., 2017). OCFAs were first assessed in a fiber supplementation study in which 21 participants received 10g/day dietary fiber for 7 days, with blood samples collected on the final day at a 420-minute study visit. Details regarding participant recruitment and eligibility, demographics, dietary interventions, study design have been published elsewhere (Byrne et al., 2019). OCFAs were further assessed in a highly controlled inpatient setting in which 19 participants consumed a high fiber (45.1g/day) and a low fiber diet (13.6g/day) for 4 days. Details regarding participant recruitment and eligibility, demographics, dietary interventions and study design have been published elsewhere (Garcia Perez et al., 2017). Sample from both studies were prepared following the extraction and derivatization protocol previously developed by Zhao et al (Zhao et al., 2017). Raw data from GC-MS targeted analysis were exported to MassHunter Qualitative Analysis Software (vB.07.01). The targeted metabolites were identified by comparing mass spectra and retention index in the in-house reference library. Thereafter, the dataset was exported to MassHunter Quantitative Analysis Software (vB.07.0) to perform baseline correction, smoothing, noise reduction, deconvolution, library searching and data integration in each chromatogram from samples and the calibration standards. The responses of the sample and standards were normalized by calculating the ratio of the peak area and the corresponding area of the internal standard as the corrected area. The squared correlation coefficient (R2) was used as a measure of linearity of the calibration curve in which the known amounts of C15:0 and C17:0 was linearly regressed against corrected area. In the first study we found that there was no effect of fiber supplementations on the serum concentrations of C15:0 and C17:0, as the changes in OCFAs concentrations were not different between control and dietary fibre supplementations (C15:0, p=0.404; C17:0, p=0.288). There were no differences in the levels of OCFAs over time, as the levels of OCFAs were not different between 0, 240, 420 minutes (C15:0, p=0.074; C17:0, p=0.503). In the second study, no differences in fasting OCFAs concentrations were found between a high fiber (45.1g/day) and a low fiber diet (13.6g/day) after 4-day inpatient period. Furthermore, OCFAs levels were not significantly different between high and low fiber diets measured after breakfast and after lunch (C15:0, p=0.286, p=0.586; C17:0, p=0.744, p=0.433 respectively). Therefore, current work do not support the proposed relationship between dietary fiber and OCFAs and suggests that further validation is required

Rapid detection of Escherichia coli O157:H7 using tunneling magnetoresistance biosensor
No full textA rapid method for the sensitive detection of bacteria using magnetic immunoassay, which are measured with a tunneling magnetoresistance (TMR) sensor, is described. For the measurement of Escherichia coli O157:H7 (E. coli O157:H7) bacteria, the target was labeled by magnetic beads through magnetic immunoassay. The magnetic beads produce a weak magnetic fringe field when external field is applied, thus induce the magnetoresistance change of TMR sensor. A detection limit of 100 CFU/mL E. coli O157:H7 bacteria in 5 hours was obtained. With its high sensitive and rapid detection scheme based on the TMR biosensor, the detection system is an excellent candidate suitable and promising for food safety and biomedical detection
