To realize accurate shake compensation in imaging processing, it is quite necessary to develop a high-precision measure system. However, in many cases, different parts of a human body may shake to different extents, resulting in greatly increasing the difficulty in conducting a reasonable measurement of body shake errors for image reconstruction. In this paper, a body shake error compensation algorithm based on the raw data is proposed. To analyze the effect of the body shake on the raw data, a model of echoed signal is rebuilt with considering both the beam scanning mode and the body shake. According to the rebuilt signal model, we derive the body shake error estimated method to compensate for the phase error. Simulation on the reconstruction of point targets with shake errors and proof-of-principle experiments on the human body in the 0.2-THz band are both performed to confirm the effectiveness of the body shake compensation algorithm proposed.展开更多

文摘Two phenomena in the history of China's economic growth during the last four decades are the increase in the share of offfarm employment and the progress in poverty alleviation in rural China.Although both of them have been well documented in the literature,less is known about the linkage between the two.To better understand the role that off-farm employment has played in poverty alleviation in rural China is critically important not only for China but also for those countries that are trying to reduce poverty.Here,we examine the impact of off-farm employment on poverty alleviation in rural China.Using the data from two nationally representative household panel surveys(China National Rural Survey and China Rural Development Survey),this paper provides supporting evidence that off-farm employment contributes to poverty alleviation in rural China.Specifically,if household participation in off-farm employment increases by 10 percentage points,the likelihood for a nonpoor household to fall into poverty will decrease by 0.88 percentage point whereas the likelihood for a poor household to climb out of poverty will increase by 3.5 percentage points.In a word,off-employment can not only prevent rural residents to fall into poverty but also help those already in poverty climb out of it.

文摘Exploring the synergy types and optimization paths between Poverty Alleviation Effectiveness and Rural Revitalization is necessary for achieving the two centenary goals.Taking poverty alleviation counties in Hunan Province,China as an example,our study proposed an indicator to measure the synergistic development between Poverty Alleviation Effectiveness and Rural Revitalization using the multi-index integrated evaluation method.Then,the coupling types were classified based on both the proposed indicator and regional characteristics.Besides,the corresponding optimization path for each coupling type was proposed to promote the synergistic development of Poverty Alleviation and Rural Revitalization.Results are as follows:1)Lower synergy focused on the southwestern Hunan,while low synergy is widely distributed(such as the west,southwest,northwest,and midland).Moderate synergy is in the midland,such as Huaihua and Chenzhou cities.High synergy is distributed in Yongzhou,Huaihua,Xiangxi cities,etc.Besides,only Hecheng City belongs to the higher synergy.2)This paper proposes corresponding development paths for different development characteristics and main problems from multiple perspectives of the protection system,industrial planning,and rural market.Continuously consolidate and enhance the effectiveness of Poverty Alleviation and Rural Revitalization to achieve coupled and synergistic development of the two systems.Our research results can provide theoretical support for implementing Poverty Alleviation and Rural Revitalization in Hunan Province,China.
文摘Poverty alleviation is a grand project involving the whole society,and is related to the development direction of socialism and the process of national modernization.It is the basic national policy and major strategic deployment of China to eliminate poverty and improve people s livelihood under the new historical conditions.Therefore,in order to win the final victory of poverty alleviation and difficulties tackling,it is not enough to have only a policy system and an institutional system.It is also necessary to establish an effective legal system to regulate and restrain various poverty alleviation behaviors,which is the basic condition for ensuring the sustainable development of poverty alleviation.
文摘This paper analyzes the evolving trends in China’s rural poverty from 1988 to 2018 and how income growth and income gaps contributed to poverty reduction using rural household data from the China Household Income Project(CHIP).We find that after China’s reform and opening up policy introduced in 1978,China’s rural poverty has been reduced substantially due primarily to income growth,although this poverty-reducing effect was partially offset by widening income gaps.During the progress of this poverty reduction,however,income distribution replaced income growth as the key driver.For the extremely poor in particular,their poverty status hinged upon income distribution.As revealed by our empirical analysis of income sources,wage income became the chief source of income for rural households,contributing a rising share to poverty reduction in the countryside.The contribution of net income from government transfer to poverty reduction has increased in recent years,and this contribution has been increased with the deepening level of poverty.Calculation of the pro-poor growth index suggests that the poor population primarily benefited from the trickle-down effect of economic growth,and the economic growth pattern has yet to lean towards pro-poor growth.

文摘BACKGROUND During the coronavirus disease 2019(COVID-19)epidemic,the fever clinic is an important link for screening and diagnosing whether a patient is infected with the novel coronavirus.Blood collection from children’s fingertips is a commonly used detection method;however,in children,the blood collection process may cause discomfort and resistance.To address this problem,the use of heating gloves combined with hand swinging can be considered for fingertip blood collection in children.AIM To explore the application of fever gloves with the handshaking method for fingertip blood collection from children in fever clinics during the COVID-19 epidemic.METHODS A total of 100 children were selected for fingertip blood collection at the fever clinic of our hospital from June 2022 to June 2023 and were divided into two groups using a randomized numerical table method,with 50 cases in each group,including the control and observation groups.The patients in the control group followed the doctor's instructions to cooperate with the routine fingertip blood collection method,and the patients in the observation group followed the doctor's instructions to cooperate with the static fever gloves with the shaking hands method of children's fingertip blood collection.The level of the six blood routine and collection indexes,and the satisfaction of the examination of the patients in the peripheral blood group and the fever gloves with the shaking hands method of the children's fingertip blood collection group were compared.RESULTS The red and white blood cell count,hemoglobin,and red blood cell pressure volume in the observation group were higher than those in the control group(P<0.05);the platelet count in the control group was lower than that in the observation group(P<0.05);the number of times of squeezing the fingertip,the average time of blood collection,and the score of puncture pain in the observation group were significantly better than those in the control group(P<0.05);and satisfaction with the routine blood examination in the observation group was greater than that in the control group.CONCLUSION The application value of the fever gloves with shaking hands method for children's fingertip blood collection was better,the accuracy of examination indexes was higher,and patient satisfaction with the examination was greater.
