Lygus pratensis distributes worldwide and is one of the common insect pests on cotton in Xinjiang Uygur Autonomous Region, the largest cotton growing region of China. This study assessed the effects of six constant temperatures (10, 15, 20, 25, 30 and 35 °C) at 60% relative humidity (RH) on egg and nymphal development of L. pratensis. Eggs failed to hatch and the newly-hatched nymphs could not normally develop at 10 °C. The developmental duration of egg and nymph decreased as temperature increased from 15 to 30 except 35 °C for egg. Based on the linear model, the lower developmental threshold and effective accumulated temperature were 10.68 °C and 150.2 DD for egg, and 12.08 °C and 208.3 DD for nymph, respectively. Among three non-linear models (Briere-1, Logan-6 and Lactin), Logan-6 provided the most accurate estimate for the mean optimum and lethal maximum temperatures (33.6 and 40.9 °C for egg, and 34.0 and 37.4 °C for nymphs). The interactive effects of three RH levels (45, 60 and 75%) and two temperatures (25 and 35 °C) on the immature developmental stages were tested. Temperature, RH and their interaction showed significant effects on egg and nymphal development. High relative humidity (75% RH) shortened the developmental duration of egg at 25 °C and nymph at 25 and 35 °C,whereas no significant difference was found for egg duration between different RH levels at 35 °C. The present study is useful for further predicting the phenology of L. pratensis and developing forecast and management strategies for this emerging mirid bug in China.

현재에도 동아시아 공동체의 미래는 예견하기 어려운 상황이다. 제일 큰 이유는 동아시아에서의 공동체 의식이 형성되어 있지 않다는 것이다. 본 논문에서는 구조주의의 시각에서 공공외교가 공동체의식 형성에 도움된다는 점을 논증하고 있다. 중국은 동아시아지역의 대국이고 동아시아 공동체의 건설과정에서 중요한 작용을 하고 있다. 본 논문에서는 중국의 공공외교의 역사를 돌아보았고 중국이 공공외교를 통해 동아시아 공동체의 건설을 위해 중요한 공헌을 할 수 있음을 강조하였다. 또한 공공외교의 신뢰성을 증가시키기 위해 중국정부는 반드시 국내시민사회의 건설에 힘써야 할 것이다.

A mouse homozygous for the spontaneous mutation uncovered(Uncv) has a hairless phenotype. A 309-bp non-frameshiftdeletion mutation in the N-terminal cytoplasmic domainof iRhom2 was identified in Uncv mice (iRhom2Uncv) using targetregion sequencing. The detailed molecular basis for howthe iRhom2 mutation causes the hairless phenotype observedin the homozygous iRhom2Uncv mouse remains unknown. Toidentify differentially expressed proteins in the skin of wild-typeand homozygous iRhom2Uncv littermates at postnatal day 5,proteomic approaches, including two-dimensional gel electrophoresisand mass spectrometry were used. Twelve proteinswere differentially expressed in the skin in a comparison betweenwild-type and homozygous iRhom2Uncv mice. A selectionof the proteomic results were tested and verified usingqRT-PCR, western blot and immunohistochemistry. These dataindicate that differentially expressed proteins, especiallyKRT73, MEMO1 and Coro-1, might participate in the mechanismby which iRhom2 regulates the development of murineskin.

This paper proposes the theoretical framework and the experimental application of an improved active disturbance rejection controller (ADRC) to speed control for the pitching axis of a remote sensing camera. Mechanical model of the pitching axis, mechatronics model of the speed control system for the pitching axis, and speed algorithm model of a permanent magnet synchronous motor are established. Control rates of the extended state observer (ESO) and the nonlinear state error feedback (NSEF) of the traditional ADRC are improved using a new nonlinear function. The nonlinear dynamics, model uncertainty, and external disturbances of the speed control system are extended to a new state, and the improved ESO is implemented to observe this state. The overtime variation of the speed control system is predicted and compensated for in real time using the improved ESO. The nonlinear integration method is adopted to nonlinearly combine the differential and the error differential by the improved NSEF. Subsequently, high-quality control is provided to the system. Simulation and experimental verification for the speed control system for the pitching axis of a remote sensing camera are conducted. Results show the effectiveness of the proposed controller.

Background: Binafuxi granules are a traditional Uighur medicine (TUM) for treating the common cold with fever. However, high-quality clinical studies supporting its efficacy and safety are lacking. Methods: In this multicenter, randomized, double-blind, placebo-controlled, phase II clinical trial, patients with common cold and fever were randomly assigned to a high-dose group, low-dose group, and placebo group in a 1:1:1 ratio. Outcomes were time to fever relief, time to fever clearance, proportion of afebrile patients, time to symptom disappearance, rate of symptom disappearance, effective rate, emergency drug usage and safety assessment. Results: A total of 235 patients were recruited. Of these, 234 were included in the full analysis set (FAS), and 217 were included in the per-protocol set (PPS). In the FAS analysis, the median time to fever relief was 6.00 h, 5.54 h and 10.65 h (P = 0.31) in the high-dose group, low-dose group and placebo group, respectively. The median time to fever clearance was 18.29 h, 20.08 h and 25.00 h (P = 0.0018), respectively, and the proportion of afebrile patients was 92.4%, 89.7% and 71.4% (P = 0.0002), respectively. There was a significant difference in the disappearance time and disappearance rate of all symptoms and of individual symptoms. No serious adverse events were found. Conclusions: Binafuxi granules can dose-dependently shorten the fever course and improve clinical symptoms in patients suffering from the common cold with fever.

<P><B>Abstract</B></P> <P>Polyelectrolyte-decorated graphene with positive and negative charges was prepared using graphene oxide as a precursor along with polyallylamine hydrochloride and poly (styrenesulfonate sodium) as surface modifiers, respectively. Driven by an electrostatic interaction, the as-obtained polyelectrolyte-decorated graphene sheets were self-assembled via a layer-by-layer method, producing graphene based composite multilayers. Field emission scanning electron microscopy (FE-SEM) images showed that the surface of composite film exhibited a mass of characteristic wrinkles of graphene. Interestingly, the cross-sectional FE-SEM of the film exhibited an unstratified structure, indicating a good dispersion of graphene sheets in the composite film. The results of oxygen gas permeability testing demonstrated that the resulting composite films exhibited excellent oxygen gas barrier properties. The oxygen gas transmission rate (OTR) of the composite film with 24 bilayers was as low as 1.2 cm<SUP>3</SUP> m<SUP>-2</SUP> d<SUP>-1</SUP>∙atm<SUP>−1</SUP>, exhibiting potential for use in packaging applications.</P>

Objective: The objective of this study was to investigate effects of supplementation of culture media from solid-state fermented Isaria cicadae (I. cicadae) on performance, serum biochemical parameters, serum immune indexes, antioxidant capacity and meat quality of broiler chickens. Methods: A total of 648 Arbor Acres male broiler chickens(1 d; average body weight, 42.93±0.47 g) were randomly assigned to 6 treatments, each with six replicates and 18 broiler chickens per replicate. Broiler chickens were fed phase I (d 1 to 21) and phase II (d 22 to 42) diets. The phase I diets were corn and soybean-meal based diets supplemented with 0%, 2%, 4%, 6%, 8%, or 10% culture media from solid-state fermented I. cicadae respectively. The phase II diets were corn and soybean-meal based diets supplemented with 0%, 1.33%, 2.67%, 4.00%, 5.32%, or 6.67% culture media from solid-state fermented I. cicadae respectively. Results: In phase I, the broiler chickens with the supplementation of culture media had increased body weight gain and feed intake (linear and quadratic, p<0.05) with increasing inclusion of culture media. The levels of serum total antioxidant capacity (T-AOC), glutathione (GSH) and superoxide dismutase (SOD) increased linearly (p<0.05). In phase II, levels of serum T-AOC and interleukin-1β increased linearly (p<0.05), and GSH increased (p<0.05). In the kidney, GSH and glutathione peroxidase (GSH-Px) concentrations increased (linear and quadratic, p<0.05) and SOD concentration increased linearly (p<0.05). Compared to the control, shear force and drip loss of breast muscle decreased (linear and quadratic, p<0.05). Drip loss of leg muscle decreased linearly and quadratically (p<0.05). Conclusion: Dietary supplementation of culture media from solid-state fermented I.cicadae which was enriched in both wheat and residual bioactive components of I. cicadae enhanced the growth performance of broiler chickens. It also improved body anti-oxidative status and contributed to improve broiler meat quality.
