Measures for the Optimization of Subgrade and Pavement Design in the Reconstruction and Expansion of Highways

In comparison to the construction of modern highway engineering,several of China’s early pavement construction concerns,such as pavement collapse,are rather clear.Limited by historical and technical factors,the subgrade and pavement design for highways lacks scientificity,thus inducing potential safety problems in the operation.In order to comprehensively improve the subgrade and pavement design as well as ensure the quality and safety of highway engineering projects,this paper takes the reconstructed and expanded highway projects as research subjects and focuses on proposing optimization measures for the subgrade and pavement design of reconstructed and expanded highways,so as to provide adequate reference.

Perioperative nursing principles guided by the concept of enhanced recovery after surgery

Objective:To explore the clinical effect of perioperative nursing guided by the concept of enhanced recovery after surgery and summarize them.Methods:Pubmed,Chinese National Knowledge Infrastructure(CNKI),Chinese Biomedical Literature Database(CBM),Wanfang Database,and VIP Database were searched to obtain the relevant literature involving enhanced recovery after surgery(ERAS)guidance,obtain the effective clinical data,review the reports in literature,and obtain the effective scheme.Results:Compared with the traditional nursing program,perioperative nursing principles guided by the concept of ERAS provide more accurate nursing care to patients and reduce the occurrence of intraoperative stress events through comprehensive nursing measures such as preoperative pre-rehabilitation measures,intraoperative body temperature and fluid management,postoperative analgesia,prevention of nausea and vomiting,early mobilization,catheter nursing,and better out-of-hospital follow-up.Conclusions:Perioperative nursing principles guided by the concept of ERAS can significantly reduce the incidence of perioperative complications,shorten the hospital stay of patients,and promote postoperative rehabilitation of patients.The transformation and implementation of this concept can bring significant benefits to hospitals,medical care,and patients.

A Research on Different Classroom Questioning Strategies Between Chinese and Foreign EFL Teachers

The application of questioning as a teaching tool has always been considered as a main part of the teaching process.Based on the viewpoint of several researchers,a survey was conducted on the application of different questioning strategies by Chinese and foreign EFL teachers in a middle school,in order to determine their effects on students’language learning output and propose measures to optimize Chinese teachers’questioning strategies for improving students’learning efficiency.This research provides preliminary results based on the data collected from the video recordings of class sessions,a questionnaire,and an interview.According to the analysis,the questioning strategies differ between Chinese and foreign EFL teachers in many aspects,such as in information seeking,offering,modification,adjustment,feedback,and so forth.

Residual index for measurement configuration optimization in robot kinematic calibration

To improve the efficiency and accuracy of kinematic calibration,the selection of measurement configurations is an important issue.In previous research,optimal measurement configurations mainly are selected by maximizing observability indices.However,the traditional observability indices only focus on the identification efficiency of the error parameters,while the purpose of robot kinematic calibration is to improve accuracy.To solve the inconsistency of the purpose between the observability index and calibration,the concept of the residual index to represent the residual distribution of the end effector after robot kinematic calibration with the measurement noise is proposed.Based on the quadratic form minimization of residuals,this article defines a specific residual index,O^(r),which is dimensionless and strictly better with the increase of measurement configurations.The indices are used to select measurement configurations in the kinematic calibration of a 5-DOF 2UPU/SP-RR hybrid robot,and the calibration results show that the proposed residual index is better than the traditional indices in the accuracy and stability of the end effector residual.

Quantum Parameter Estimation: From Experimental Design to Constructive Algorithm

In this paper we design the following two-step scheme to estimate the model parameter ω0 of the quantum system: first we utilize the Fisher information with respect to an intermediate variable v = cos(ω0 t) to determine an optimal initial state and to seek optimal parameters of the POVM measurement operators; second we explore how to estimate ω0 from v by choosing t when a priori information knowledge of ω0 is available. Our optimal initial state can achieve the maximum quantum Fisher information. The formulation of the optimal time t is obtained and the complete algorithm for parameter estimation is presented. We further explore how the lower bound of the estimation deviation depends on the a priori information of the model.

Prefect Protection of Quantum-Enhanced Metrology from Dephasing Noise

One of the main obstacles for quantum-enhanced metrology is that the estimation accuracy enhanced by non-classical states is likely to be obliterated by noises. Here, we consider a scenario of phase estimation suffering from pure dephasing noise which is taken into account after the phase parameter being imprinted, and propose a scheme to effectively protect the quantum enhancement from both correlated and uncorrelated dephasing sources by performing a rotation operation prior to the noise. By invoking the Fisher information approach, we strictly prove that a π/2 rotation is the ideal one which can completely resist the influence of the phase noise for all real symmetric pure states and the optimal measurement approaching the ultimate sensitivity set by quantum Cramér–Rao bound is presented.Additionally, we numerically study the availability of the scheme with arbitrary angle rotation for different probe states and show that our scheme will still robust for general symmetric pure states even with non-ideal rotation operation.
