| 1 | Amblyopia screening for first and second-grade children in Jordan显示文摘AIM:To share the results of a national screening program for amblyopia in school children in the north of Jordan.METHODS:This is a prospective national screening study for amblyopia.The program rolls first and second-grade children(6 to 7 years old) in the north of Jordan.The eye examination included:best-corrected visual acuity,cover-uncover test,and cycloplegic retinoscopy.Monocular visual acuity was tested using an ETDRS visual acuity chart without correction.Moreover,children were tested with full cycloplegic refraction when the test criteria were met.Unilateral amblyopia was defined as a best-corrected visual acuity difference of 2 or more lines.In comparison,bilateral amblyopia was defined as a best-corrected visual acuity of 20/40 or worse in the best eye.RESULTS:The prevalence of amblyopia for the total sample tested(n=17 203) was 2.78%(n=479).The most common cause of amblyopia was hypermetropia(64.45%),followed by previous ocular surgeries(15.1%),myopia(10.43%),strabismus(9.39%),and congenital cataract(0.63%).CONCLUSION:This is the first and only study,identifing modifiable risk factors in Jordanian children with amblyopia.In their first couple of years of elementary education,many Jordanian children are affected by amblyopia and pass unnoticed.A more governmental effort is needed into screening programs to improve vision in the Jordanian population. | Khalil M.Al-Salem Mohammad S.Saleem Ismat Ereifej Hamzeh M.Alrawashdeh Rayed Falah Hussein Obeidat Asma Ali Abdlmohdi Raeda Zaki Al-Momani Layal Mohammed Hammad Omar Ahmad al-Habahbeh Yaqeen M.Assassfeh Laith Ramzi Najib Al-Qsous Ashraf Hatim Adeeb Nasraween Tariq A.Al Maaitah Deya'-Aldin Muneer Hasan Aqeel Ibtehal Eyadeh Awad Alabdulrazzg Abdullah Mahmoud Mohammad Murad Amany Jehad Faleh AL-Zurqan Enas Jamal Mohammad Jaradat Slsabela Emad Suliman Aldhoon Ala'a Majed Dmour Ahmad Talal Asassfeh Jeries Ayman Halaseh Abdel Aziz Ammar Daoud Waha Ayman Alkasasbeh Kholoud GH.Matar | 2022 | International Journal of Ophthalmology(English edition)2022，15，2： | 1 |

| 5 | Power Reallocation and Complexity Enhancement for Beyond 4G Systems显示文摘Competitiveness in the modern wireless systems’provided services is a key factor in the development,in addition to the adaptation to/harmonization of user demand.Therefore,this paper discussed the quality of services from the point of view of the need for supporting the needed data rates.For this purpose,a benchmark based on Multi-Antenna Multiband Orthogonal Frequency Division Multiplexing has been proposed to compatible with Ultra-Wideband systems such as the fifth generation based technologies.In order to enhance the system quality of service,the structure of the ultra-wideband system’s main stage;namely Orthogonal Frequency Division Multiplexing has been modified by imposing a low complexity designed Haar-wavelets stage instead of the fast Fourier transform stage.This is in addition to reallocate the transmitted power in order to reduce the effect of one of the main drawbacks that is found in the Orthogonal Frequency Division Multiplexing;namely the peak-to-average power ratio problem.A MATLAB simulation has been performed in order to validate the propositions that have been made based on six different performance factors.As a result,the new propositions were achieved our targets by reducing the system’s complexity in terms of mathematical operations and by giving promising results in managing the transmitted powers.Furthermore,the effectiveness of such work has been verified and compared with four different work in the literature。 | Omar Daoud | 2019 | China Communications2019，16，6： | 0 |
