AIM: To evaluate the effect of scleral encircling bands on the development and progression of diabetic retinopathy(DR) in diabetic patients.METHODS: The medical records of diabetic patients who underwent unilateral retinal detachment(RD) surgery using scleral buckle and encircling band were reviewed retrospectively. Both eyes of patients were included in the study: one eye in each patient had a scleral buckle with encircling band(the operated eye) and the other one is the non-operated eye. The demographic characters, duration of diabetes and period between surgery and the last recall visit were retrieved from each patient. All the cases underwent fundus photo and fluorescein angiography(when indicated) to confirm the DR staging.RESULTS: Totally 25 patients fulfilled the inclusion and the exclusion criteria were become eligible for the study. A total of 50 eyes of 25 patients were enrolled in this analysis. The mean period of time passed from surgery with encircling band and the last reassessment visit was 12.5±2 y. Even though DR could develop in the operated eyes, it was at a less degree of severity compared to the non-operated eyes of same patients(P=0.027).CONCLUSION: Scleral encircling bands have protective effects against the development and progression of DR. 展开更多

Following the observation of candidate chiral doublet bands in 78,80Br, triaxial deformations with corresponding configurations in odd-odd bromine isotopes have been investigated using adiabatic and configuration-fixed constrained triaxial relativistic-meanfield calculations with an aim of finding the boundary of chirality in the chain of Br isotopes. Several minima with triaxial deformation and the proper particle-hole configuration were obtained in 74,76,78,80,82Br, where the chiral doublet bands have the possibility of occurrence. Furthermore, the possible existence of multiple chiral doublet(MχD) bands is demonstrated in 74,76,78,80,82Br.Experiments to explore the chirality and MχD properties of Br isotopes are conducted to verify the predictions. 展开更多

In this Letter, a photonic crystal(PC) flat lens with a scatterer-size gradient is proposed, which simultaneously achieves imaging of the point source and sub-wavelength focusing of the plane wave in the first, second, and fifth bands. The imaging of the point source breaks through the diffraction limit in the second and fifth bands. The PC flat lens with the scatterer-size gradient is expected to be used in a new multifunctional optical imaging and focusing device, which improves the application potential of a PC flat lens. 展开更多

The broadband,narrow width,rectangular dielectric resonator antenna(RDRA)of aluminum nitride(εr=8.6)was designed and the effect of inclusion of air gap at the bottom of the dielectric resonator antenna(DRA),above the ground plane,was investigated.Gain around 7 dBi was obtained for DRA with air gap(DRAAG)over a broad bandwidth in upper X,Ku,and K bands.Further enhancement in gain could be obtained by placing a metal wall parallel to the length of DRA.However,due to the presence of metal wall,bandwidth was reduced.These structures with the metal wall are capable of operating over a wide band extending from Ku band to lower K band with the gain of around 10 dBi.CST Microwave Studio Software was used to simulate all these structures.Performance parameters of DRA with air gap were compared with several broadband DRA structures reported in recent literature.The proposed DRAAG with the metal wall in this paper is capable of operating over a wide bandwidth along with a significant gain. 展开更多

Nodal line semimetal(NLS) is a new quantum state hosting one-dimensional closed loops formed by the crossing of two bands. The so-called type-Ⅱ NLS means that these two crossing bands have the same sign in their slopes along the radial direction of the loop, which requires that the crossing bands are either right-tilted or left-tilted at the same time. According to the theoretical prediction, Mg3Bi2 is an ideal candidate for studying the type-Ⅱ NLS by tuning its spin-orbit coupling(SOC). High-quality Mg3 Bi2 films are grown by molecular beam epitaxy(MBE). By in-situ angle resolved photoemission spectroscopy(ARPES), a pair of surface resonance bands around theГ point are clearly seen. This shows that Mg3Bi2 films grown by MBE are Mg(1)-terminated by comparing the ARPES spectra with the first principles calculations results. Moreover, the temperature dependent weak anti-localization effect in Mg3Bi2 films is observed under magneto-transport measurements, which shows clear two-dimensional(2 D) e-e scattering characteristics by fitting with the Hikami–Larkin–Nagaoka model. Therefore, by combining with ARPES, magneto-transport measurements and the first principles calculations, this work proves that Mg3Bi2 is a semimetal with topological surface states. This paves the way for Mg3Bi2 to be used as an ideal material platform to study the exotic features of type-Ⅱ nodal line semimetals and the topological phase transition by tuning its SOC. 展开更多

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 or two bands cross respectively. 3D crystals with both kinds of band structure have been found in recent years, which completes a search that began in the 1930s w让h the work of Conyers Herring. 展开更多

Water quality is critical to ensure that marine resources and the environment are utilized in a sustainable manner. The objective of this study is therefore to investigate the optimum placement of marine environmental monitoring sites to monitor water quality in Shanghai, China. To improve the mapping or estimation accuracy of the areas with different water quality grades, the monitoring sites were fixed in transition bands between areas of different grades rather than in other positions. Following bidirectional optimization method, first, 18 candidate sites were selected by filtering out specific site categories. Second, three of these were, in turn, eliminated because of the rule defined by the changes in the areas of water quality grades and by the standard deviation of the interpolation errors of dissolved inorganic nitrogen(DIN) and phosphate(PO_4-P). Furthermore, indicator kriging was employed to depict the transition bands between different water quality grades whenever new sampling sites were added. The four optimization projects of the newly added sites reveal that, all optimized sites were distributed in the transition bands of different water grades, and at the same time in the areas where the historical sites were sparsely distributed. New sites were also found in the overlap region of different transition bands. Additional sites were especially required in these regions to discriminate the boundaries of different water quality grades. Using the bidirectional optimization method of the monitoring sites, the boundaries of different water quality grades could be determined with a higher precision. As a result, the interpolation errors of DIN and PO_4-P could theoretically decrease. 展开更多

A least squares fitting approach is used. The root mean square deviations between thedetermined and the observed transition energies are calculated by extracting the model parameters using the powerindex formula. Whenever definite spins are available, the determined and the observed transition energies are inaccordance with each other. The computed values of dynamic moment of inertia j(2) obtained by using the powerindex formula and its deviation with the rotational frequency is also studied. Excellent agreement is shown betweenthe calculated and the experimental results for j(2) versus the rotational frequency. Hence, the power index formulaworks very well for all the SD bands in Hg isotopes expect for 195Hg(2, 3, 4). 展开更多

Neuromuscular disorders are a group of diseases affecting the neuro-musculo-skeletal system.Children with neuromuscular disorders frequently develop progressive spinal deformities with cardio-respiratory compromise in the most severe cases.The incidence of neuromuscular scoliosis is variable,inversely correlated with ambulatory abilities and with a reported risk ranging from 80%to 100%in non-ambulatory patients.As surgical and peri-operative techniques have improved,more severely affected children with complex neuromuscular deformities and considerable co-morbidities are now believed to be candidates for extensive surgery for spinal deformity.This article aimed to provide a comprehensive review of how neuromuscular spinal deformities can affect normal spine balance and how these deformities can be treated with segmental instrumentation and sub-laminar devices.Older concepts have been integrated with newer scientific data to provide the reader with a basis for better understanding of how treatment of neuromuscular scoliosis has evolved over the past few decades.Recent advances,as well as challenges that remain to be overcome,in the surgical treatment of neuromuscular curves with sub-laminar devices and in the management of post-operative infections are outlined. 展开更多
