Opto-thermal transient emission radiometry(OTTER) is a infrared remote sensing technique, which has been successfully used in in vivoskin moisture content and skin moisture depth profiling measurements. In present paper, we extend this moisture content measurement capability to analyze the moisture content of fruit(tomato, grape, etc.) skins, and to study the relationship between fruits ripening process and their surface moisture and moisture depth profiles.

International Journal of Ophthalmology(English edition) 2016年第3期9卷 395-398页

AIM： To Investigate the added value of using a Diaton transpalpebral tonometer （DT） to measure lOP in keretoconus. Most type of tonometers use corneal applanation or biomechanical resistance to measure intraocular pressure （lOP）; however, these factors can be altered by keratoconus. Specifically, we examined whether DT can detect false-negative low Goldmann applanation tonometry （AT） measurements. METHODS： Patients with keratoconus were recruited from our tertiary academic treatment center. Measurements included AT and DT （in random order） and Scheimpflug imaging. An age- and gender-matched group of control subjects with no history of corneal disease or glaucoma was also recruited. RESULTS： In total, 130 eyes from 66 participants were assessed. In the keratoconus group, mean AT was 11.0± 2.6, mean DT 11±5.5 （P =0.729）and the two measures were correlated significantly（P=0.006, R=0.323）. However, a Bland-Altman plot revealed a wide distribution and poor agreement between both measurements. Previous corneal crosslinking, corneal pachymetry, and Krumeich classification had no effect on measured IOP. CONCLUSION： Measurements obtained using a Diaton tonometer are not affected by corneal biomechanics; however, its poor agreement with Goldmann AT values calls into question the added value of using a Diaton tonometer to measure lOP in keratoconus.

自21世纪初开放获取运动兴起以来,科学研究过程中的文献访问障碍在一定程度上被消除,学术出版传播的模式也不断革新。随着互联网、大数据、人工智能等现代技术发展日益成熟并广泛运用于学术出版与交流,科技期刊已经从传统的、印刷形式为主的静态单刊,演化为单刊数字平台、刊群平台、集团平台、纯数字平台。三大变革影响着科技出版的过去和未来。第一是印刷向数字出版的过渡,期刊出版已将近完成了这一转变,这一数字化转变可称为可及性的变革。
