OBJECTIVE: To determine the effectiveness of pediatric Tuina(PT) in preventing recurrent acute respiratory tract infections(ARTIs) in children. METHODS: This is a retrospective cohort study based on the electronic medical records of children with recurrent ARTIs in 2016. Children were divided into a PT group or a non-PT group, according to whether they had received PT or not in 2016. The primary outcome was the number of ARTI episodes in 2017 and 2018. The secondary outcomes were the number of ARTIs leading to outpatient department visits and outpatient antibiotic prescriptions due to ARTIs in the same time period. Negative binomial regressions were used to detect the association between PT and the outcomes. RESULTS: A total of 2303 children were included in the analysis, including 94 in the PT group and 2209 in the non-PT group. Children who received PT six or more times in 2016 had fewer episodes of ARTIs in 2017 [incidence rate ratio(IRR): 0.59, 95% confidence interval(CI)(0.42-0.84)] and 2018 [IRR: 0.58, 95% CI(0.36-0.94)] and fewer outpatient department visits due to ARTIs in 2017 [IRR: 0.56, 95% CI(0.38-0.83)] than children who had not received PT in 2016. There was no significant difference in the number of outpatient antibiotic prescriptions between the two groups. CONCLUSIONS: Receiving PT six or more times within one year is associated with a decrease in recurrent ARTIs in children in the following two years. Randomized controlled trials are needed for effect evaluation prior to establishing PT as a method for preventing recurrent ARTIs among children.

Defects evolution in n-type 4H-SiC induced by electron irradiation and annealing

Radiation damage produced in 4H-SiC by electrons of different doses is presented by using multiple characterization techniques. Raman spectra results indicate that SiC crystal structures are essentially impervious to 10 Me V electron irradiation with doses up to 3000 kGy. However, irradiation indeed leads to the generation of various defects, which are evaluated through photoluminescence(PL) and deep level transient spectroscopy(DLTS). The PL spectra feature a prominent broad band centered at 500 nm, accompanied by several smaller peaks ranging from 660 to 808 nm. The intensity of each PL peak demonstrates a linear correlation with the irradiation dose, indicating a proportional increase in defect concentration during irradiation. The DLTS spectra reveal several thermally unstable and stable defects that exhibit similarities at low irradiation ***, after irradiating at the higher dose of 1000 kGy, a new stable defect labeled as R_(2)(Ec-0.51 eV) appeared after annealing at 800 K. Furthermore, the impact of irradiation-induced defects on SiC junction barrier Schottky diodes is discussed. It is observed that high-dose electron irradiation converts SiC n-epilayers to semi-insulating layers. However, subjecting the samples to a temperature of only 800 K results in a significant reduction in resistance due to the annealing out of unstable defects.

Transformation optics(TO) provides an unprecedented technique to control electromagnetic(EM) waves by engineering the constitutive parameters of the surrounding medium through a proper spatial transformation. In general, ideal transformation optical devices require simultaneous electric and magnetic responses along all three dimensions. To ease the practical implementation, previous studies usually made use of reduced parameters or other simplified approaches, which inevitably introduce extra reflection or unwanted phase shift. Up to today, experimental realizations of full-parameter transformation optical devices in free space are still quite limited. Here, a general design strategy is proposed to solve this *** a specific example, a full-parameter spatial-compression TO medium with constitutive parameters taking the diagonal form diag(a, a, 1/a) for the TM wave incidence was designed and realized experimentally. Such spatial-compression TO media were then applied to the implementation of an ideal omnidirectional invisibility cloak capable of concealing a large-scale object over a wide range of illumination angles. Both the simulation and experiment confirm that the cloak allows for nearly unity transmission of EM waves in the forward direction without introducing extra scattering or phase shift. This work constitutes an important stepping stone for future practical implementation of arbitrary full-parameter omnidirectional transformation optical devices.
