Objective:To explore the correlation between nurses’attitude and practice toward physical restraint(PR)in psychiatric settings and identify the factors that influence the use of ***:A cross-sectional survey was conducted.A self-designed questionnaire containing a PR scale was used to assess the attitude and practice of registered psychiatric nurses in Guangdong,China,from November 1,2018 to December 31,*** statistics,the Mann–Whitney U test,the Kruskal–Wallis test,and ordinal regression analysis were used to analyze the ***:The response rate was 74.6%.The nurses’responses showed neutral attitude and a moderate level of practice regarding the use of *** such as age,gender,marital status,professional position,nightshift,and the frequency of training programs on PR showed a significant association with nurses’attitude and practice concerning PR(P<0.05).In addition to these factors,this study found that the practice of PR was associated with nurses’attitude toward it(P<0.05).Our results showed that nurses with a largely negative attitude toward PR were more likely to use it(OR=1.91,P<0.001).Conclusions:Clinically,psychiatric nurses with negative attitude are more likely to practice *** and education programs are highly recommended for nursing managers to change the nursing staff’s attitude,since their attitude may have an impact on the PR what they practice.

针对飞机机翼壁板数字化装配过程中蒙皮外形快速扫描的需求,对蒙皮的扫描路径进行自动规划.介绍激光扫描仪扫描测量的原理及方法,并分析扫描仪扫描样点时的倾角、距离及扫描宽度等约束条件.以大尺寸件机翼蒙皮为研究对象,对其进行数字化离散操作,得到一系列样点.使用最小二乘法对上述样点进行自动分组.在此基础上把扫描过程分为扫描测量和姿态调整2种动作交替运动的组合,构建以扫描过程总时间为最小的优化目标函数.利用遗传算法求解目标函数,从而优化三维空间的扫描路径,并将此路径与常见的梯形扫描和直线扫描路径进行比较,扫描总路径短且所用总姿态数少,平均扫描效率提高14.4%.最后,采用DELMIA软件平台进行扫描过程仿真,利用搭载扫描仪的机器人沿优化路径进行扫描.结果显示:本研究可满足扫描约束要求,且扫描仿真时间与计算时间一致.

Herein, the de novo synthesis of atropisomeric benzofurans through the Cu/spirocyclic-pyrrolidine-oxazoline(SPDO) complex catalyze asymmetric formal [3 + 2] cycloaddition between quinones and ynamides is explored, producing a range of structurally diverse axially chiral benzofurans in satisfactory yields with good to excellent enantioselectivities. Furthermore, density functional theory calculations were applied to explain the possible reaction mechanism.

Remarks on the Single-Photon Spectra from CERN-WA80

Chinese Physics Letters 1996年第9期13卷 656-659页

作者： ai xiao-bai Institute of Nuclear Research Chinese Academy of SciencesShanghai 201800

In this letter the author points out that in recent WA80 data an apparent slope parameter of Texp≈180 MeV/c must not mean the fireball becoming equilibrated in whole at some temperatures throughout the stages of the *** author also demonstrates that Texp is merely a mean value of the temperatures of various high-energy photon sources,and predicts that for higher colliding energies(>200 A GeV)the shape of the measured single-photon spectra would exhibit some concave curvature,which may be used as a probe for diagnosing quark-gluon plasma.

Objective Exosomal long noncoding RNAs(lnc RNAs) are the key to diagnosing and treating various diseases. This study aimed to investigate the diagnostic value of plasma exosomal lnc RNAs in white matter hyperintensities(WMH).Methods We used high-throughput sequencing to determine the differential expression(DE) profiles of lnc RNAs in plasma exosomes from WMH patients and controls. The sequencing results were verified in a validation cohort using q RT-PCR. The diagnostic potential of candidate exosomal lnc RNAs was proven by binary logistic analysis and receiver operating characteristic(ROC) curves. The diagnostic value of DE exo-lnc RNAs was determined by the area under the curve(AUC). The WMH group was then divided into subgroups according to the Fazekas scale and white matter lesion site, and the correlation of DE exo-lnc RNAs in the subgroup was *** In our results, four DE exo-lnc RNAs were identified, and ROC curve analysis revealed that exolnc_011797 and exo-lnc_004326 exhibited diagnostic efficacy for WMH. Furthermore, WMH subgroup analysis showed exo-lnc_011797 expression was significantly increased in Fazekas 3 patients and was significantly elevated in patients with paraventricular matter *** Plasma exosomal lnc RNAs have potential diagnostic value in WMH. Moreover, exolnc_011797 is considered to be a predictor of the severity and location of WMH.
