AIM：To assess the proportion of refractive errors in the Mexican population that visited primary care optometry clinics in fourteen states of Mexico. METHODS：Refractive data from 676 856 patients aged 6 to 90 y were collected from optometry clinics in fourteen states of Mexico between 2014 and 2015. The refractive errors were classified by the spherical equivalent（SE）, as follows：sphere＋？ cylinder. Myopia（SE〉-0.50 D）, hyperopia（SE〉＋0.50 D）, emmetropia（-0.50≤SE≤＋0.50）, and astigmatism alone（cylinder≥-0.25 D）. A negative cylinder was selected as a ***：The proportion（95% confidence interval） among all of the subjects was hyperopia 21.0%（20.9-21.0）, emmetropia 40.7%（40.5-40.8）, myopia 24.8%（24.7-24.9） and astigmatism alone 13.5%（13.4-13.5）. Myopia was the most common refractive error and frequency seemed to increase among the young population（10 to 29 years old）, however, hyperopia increased among the aging population（40 to 79 years old）, and astigmatism alone showed a decreasing trend with age（6 to 90y; from 19.7% to 10.8%）. There was a relationship between age and all refractive errors（approximately 60%, aged 50 and older）. The proportion of any clinically important refractive error was higher in males（61.2%） than in females（58.3%; P〈0.0001）. From fourteen states that collected information, the proportion of refractive error showed variability in different geographical areas of ***：Myopia is the most common refractive error in the population studied. This study provides the first data on refractive error in Mexico. Further programs and studies must be developed to address the refractive errors needs of the Mexican population.

Optical properties of Weyl semimetals

引用

National Science Review 2019年第2期6卷 206-208页

作者： joel E.Moore Department of Physics University of California Materials Science Division Lawrence Berkeley National Laboratory

The behavior of electrons in ordinary metals is dominated by physics near the Fermi surface. Indeed, many of the first successes of the quantum theory of solids, such as understanding the large specific heat of metals, followed from applications of the Fermi surface concept. Great effort has been devoted in recent years to semimetals in which the Fermi surface shrinks to a set of Dirac or Weyl points, where four

In 2010 the effects of the global financial crisis were still being felt in the UK. Stock market confidence levels were low, unemployment levels were high and job opportunities were few and far between especially for new graduates with little work experience. Unfortunately for my partner, her recent graduation and search for job opportunities within the finance and law sector could not have come at a more unsuitable time. China however had better weathered the storm of the financial crisis and presented itself as a more familiar and fruitful climate for my partner to further develop her career. Furthermore.

The evolution and refinements of varicocele surgery

引用

Asian Journal of Andrology 2016年第2期18卷 171-178,J0002页

作者： joel L Marmar Director of Men's Health Services Planned Parenthood of Southern New Jersey 317 S. Broadway Camden NJ 08103 USA.

Varicoceles had been recognized in clinical practice for over a century. Originally, these procedures were utilized for the management of pain but, since 1952, the repairs had been mostly for the treatment of male infertility. However, the diagnosis and treatment of varicoceles were controversial, because the pathophysiology was not clear, the entry criteria of the studies varied among centers, and there were few randomized clinical trials. Nevertheless, clinicians continued developing techniques for the correction of varicoceles, basic scientists continued investigations on the pathophysiology of varicoceles, and new outcome data from prospective randomized trials have appeared in the world＇s literature. Therefore, this special edition of the Asian Journal of Andrology was proposed to report much of the new information related to varicoceles and, as a specific part of this project, the present article was developed as a comprehensive review of the evolution and refinements of the corrective procedures.

ON THE ALGORITHMIC COMPLEXITY OF STATIC STRUCTURES

引用

Journal of Systems Science & Complexity 2010年第6期23卷 1037-1053页

This paper provides a first indication that this is true for a system comprised of a static structure described by hyperbolic partial differential equations and is subjected to an external random input force. The system deforms the randomness of an input force sequence in proportion to its algorithmic complexity. The authors demonstrate this by numerical analysis of a one-dimensional vibrating elastic solid （the system） on which we apply a maximally-random force sequence （input）. The level of complexity of the system is controlled via external parameters. The output response is the field of displacements observed at several positions on the body. The algorithmic complexity and stochasticity of the resulting output displacement sequence is measured and compared against the complexity of the system. The results show that the higher the system complexity, the more random-deficient the output sequence.

Perspectives on the clinical management ocalized prostate cancer

引用

Asian Journal of Andrology 2014年第4期16卷 511-514页

作者： joel B Nelson Department of Urology University of Pittsburgh School of Medicine Pittsburgh Pennsylvania USA.

Defined broadly, prostate cancer has two states： An indolent histologicalmanifestation of a locally proliferative and invasive process or a clinically relevant, potentially lethal disease. Likewise, the management of clinically localized prostate cancer must address two questions： what sort of disease is this and what needs to be done.
