Shi, Guanglin,Shen, Qin,Zhang, Caixin,Ma, Jun,Mohammed, Anaz,Zhao, Huan The Korean Academy of Tuberculosis and Respiratory 2018 Tuberculosis and Respiratory Diseases Vol.81 No.3
Despite recent clinical guidelines, the optimal therapeutic strategy for the management of refractory chronic cough is still a challenge. The present systematic review was designed to assess the evidence for efficacy and safety of gabapentin in the treatment of chronic cough. A systematic search of PubMed, Embase, Cochrane Library databases, and publications cited in bibliographies was performed. Articles were searched by two reviewers with a priori criteria for study selection. Seven relevant articles were identified, including two randomized controlled trials, one prospective case-series designed with consecutive patients, one retrospective case series of consecutive patients, one retrospective case series with unknown consecutive status, and two case reports comprising six and two patients, respectively. Improvements were detected in cough-specific quality of life (Leicester Cough Questionnaire score) and cough severity (visual analogue scale score) following gabapentin treatment in randomized controlled trials. The results of prospective case-series showed that the rate of overall improvement of cough and sensory neuropathy with gabapentin was 68%. Gabapentin treatment of patients with chronic cough showed superior efficacy and a good safety record compared with placebo or standard medications. Additional randomized and controlled trials are needed.

This paper investigates the fuzzy position/force hybrid control for a class of 5-degree-of-freedom (DOF) redundantly actuated parallel robots. The position control law is designed based on the proportional-integraldifferential (PID) for the 5-DOF redundantly actuated parallel robot. The fuzzy proportional-integral (PI) redundant actuation force control law is designed based on the position/force hybrid control structure for the 5-DOF redundantly actuated parallel robot. The optimum driving force is obtained in the presence of interference, and the force tracking performance of the fuzzy PI controller is better than the conventional PI controller under the interference condition. Based on the fuzzy position/force hybrid controller, the tracking performance of the closed-loop system for the 5-DOF redundantly actuated parallel robot is improved by using the fuzzy position/force hybrid controller and the interference is eliminated effectively in the control system design. Finally, the co-simulation results of ADAMS and MATLAB/SIMULINK are given to show the effectiveness and advantages of the proposed methodscompared with the conventional PI controller.

This paper addresses the problem of robust waveform design for distributed multiple-radar systems (DMRSs) based on low probability of intercept (LPI), where signal-to-interference-plus-noise ratio (SINR) and mutual information (MI) are utilized as the metrics for target detection and information extraction, respectively. Recognizing that a precise characterization of a target spectrum is impossible to capture in practice, we consider that a target spectrum lies in an uncertainty class bounded by known upper and lower bounds. Based on this model, robust waveform design approaches for the DMRS are developed based on LPI-SINR and LPI-MI criteria, where the total transmitting energy is minimized for a given system performance. Numerical results show the effectiveness of the proposed approaches.

The aim of this study was to determine the photosynthetic adaptability of Rhododendron species toalpine environments. The chlorophyll fluorescence parameters and rapid light response curves ofeight Rhododendron species were determined under field conditions across elevation gradients (atelevations of 2,950, 3,560, 3,660, 3,770, and 4,030 m) in the Jiaozi Mountain National NaturalReserve, Yunnan Province, southwestern China. The effect of different elevations, species, and theirinteractions significantly affected most of the chlorophyll fluorescence and rapid light response curveparameters. The variable to maximum fluorescence ratio (Fv/Fm) ranged from 0.78 to 0.81 at the fiveelevation gradients. This result indicated that the studied species were well grown and adapted to thecurrent environment. The correlation analysis indicated that the elevation was positively significantlycorrelated with the photochemical efficiency of photosystem II, electron transport rate, maximumelectron transport rate, light saturation coefficient (Ek), and chlorophyll relative content (SPAD: leafchlorophyll content index) and was negatively significantly correlated with photochemicalquenching, nonphotochemical quenching, and linear initial slope values. Although no significantrelationship was observed between the elevations and Fv/Fm, the apparent difference in Fv/Fm both atelevation gradients and elevation × species levels indicated that the Rhododendron speciesdemonstrated species-specific adaptation to the environment at different elevations. Our resultsprovided evidence that Rhododendron species exhibit variations in photosynthetic activities in analpine environment at different elevations. These differences may improve the understanding of thephysiological adaptation variations of Rhododendron species across elevation gradients in associationwith climate change in the mountains of southwestern China.
Roasting and leaching process of iron sulfate to separate zinc and iron from blast furnace dust
Ruimeng Shi,Hao Wu,Huan Liu,Bixia Wang,Yuan She,Chong Zou,Jiangfeng Zheng,Qi Gao 한국화학공학회 2022 Korean Journal of Chemical Engineering Vol.39 No.5
The physical phase analysis and thermodynamic calculations of blast furnace dust were performed using Xraydiffraction fluorescence spectrometer, X-ray diffractometer, scanning electron microscope, energy spectrometer, andFactsage software. The leaching pattern and mechanism of zinc elements were studied by a roasting-leaching method. The results showed that the conversion of zinc ferrite to zinc sulfate could be realized when the roasting temperaturerange was 500-730 oC, which was convenient for zinc leaching. A better roasting condition could be obtained when theroasting temperature was 600 oC, roasting time was 60 min, and molar ratio of ferric sulfate was 1.2 : 1. Under theseconditions, the zinc and iron leaching rates were 84.57% and 24.51%, respectively, at a sulfuric acid concentration of110 gL1, liquid-solid ratio of 10 : 1 mLg1, leaching time of 60min, stirring speed of 400 rpm, and leaching temperatureof 80 oC. The leaching process of zinc from blast furnace dust sulfate roasting products agreed with the unreacted coremodel, and internal diffusion was the restrictive step. The kinetic equation of the leaching process was 12R/3(1R)2/3=0.47t, the apparent activation energy of the leaching reaction was 17.4 kJmol1, and the reaction order was 1.908.

Reactive adsorption desulfurization (RADS) experiments were conducted over a series of commercial metal oxide supports (Al2O3-, SiO2-, TiO2- and ZrO2-) supported Ni/ZnO adsorbents. The adsorbents were characterized by X-ray diffraction (XRD), temperature programmed reduction (TPR), and Fourier transform infrared spectroscopy (FTIR) in order to find out the influence of specific types of surface chemistry and structural characteristics on the sulfur adsorptive capacity. The desulfurization performance of all the studied adsorbents decreased in the following order: Ni/ZnO-TiO2 > Ni/ZnO-ZrO2 > Ni/ZnO-SiO2 > Ni/ZnO-Al2O3. Ni/ZnO-TiO2 shows the best performance and the three hour sulfur capacity can achieve 12.34 mg S/g adsorbent with a WHSV of 4 h−1. Various characterization techniques suggest that weak interaction between active component and support component, high dispersion of NiO and ZnO, high reducibility and large total Lewis acidity of the adsorbents are important factors in achieving better RADS performance.

Yufei Wu,Huan Zhang,Xiaofen Liu,Zhangyan Shi,Hongling Li,Zhibin Wang,Xiaoyong Jie,Shao-Ping Huang,Fu-Chang Zhang,Junlin Li,Ke-Jin Zhang,Xiao-Cai Gao 한국유전학회 2019 Genes & Genomics Vol.41 No.1
Mutations of Aristaless-related homeobox (ARX) gene were looked as the third cause of non-syndromic intellectual disability (NSID), while the boundary between true disease-causing mutations and non-disease-causing variants within this gene remains elusive. To investigate the relationship between ARX mutations and NSID, a panel comprising six reported causal mutations of the ARX was detected in 369 sporadic NSID patients and 550 random participants in Chinese. Two mutations, c.428_451 dup and p.G286S, may be disease-causing mutations for NSID, while p.Q163R and p.P353L showed a great predictive value in female NSID diagnosis with significant associations (X2 = 19.60, p = 9.54e−6 for p.Q163R; X2 = 25.70, p = 4.00e−07 for p.P353L), carriers of these mutations had an increased risk of NSID of more than fourfold. Detection of this panel also predicted significant associations between genetic variants of the ARX gene and NSID (p = 3.73e−4). The present study emphasized the higher genetic burden of the ARX gene on NSID in the Chinese population, molecular analysis of this gene should be considered for patients presenting NSID of unknown etiology.
