The belief rule base is crucial in expert systems for intelligent diagnosis of equipment. However, in the belief rule base for fault diagnosis, multiple antecedent attributes are often initially determined by domain experts. Multiple fault symptoms related to multiple antecedent attributes are different when an actual fault occurs. This leads to multiple antecedent attributes matching with multiple fault symptoms non-simultaneously, thereby resulting in a fault diagnosis lacking timeliness and accuracy. To address this issue, this paper proposes a method for belief rule-based optimization based on Naive Bayes theory. First, a fault sample is taken in a long enough window and divided into several interval samples, making the analysis samples approximate the overall samples. Second, using Gaussian mixture clustering and Naive Bayes optimization, iteration is performed over the threshold and limit values of fault symptoms in the belief rule base based on the requirements of the timeliness and accuracy of fault diagnosis results. Finally, the belief rule base is optimized. Using fault samples from high-pressure heaters and condensers, the validation results show that there is a there is a significant improvement in the timeliness and accuracy of fault diagnosis with the optimal belief rule base.

The QuEChERS extraction technique is a pretreatment technique that has been rapidly applied in recent years and is widely used in the field of pesticide residues with many advantages. This technique is based on solid phase extraction (SPE), which uses the interaction between adsorbent and impurities in the matrix to achieve the purpose of purification. The method has easier operation and better purification effect than SPE. In this paper, the research progress of the QuEChERS technique in pesticide residue detection in different fields in recent years and its future development were reviewed, hoping to provide reference for further development and utilization of the QuEChERS technique in pesticide residue detection in the future.

Recent work has established that model texts could be employed as a useful feedback technique. However, few studies have employed argumentative writing tasks and analyzed draft quality, and little is known about the role played by the language analytic ability in using model texts. The current study aimed to investigate what Chinese EFL learners (n = 60) noticed at the composition and comparison (comparing their texts with model texts) processes in a four-stage argumentative writing task and explore to what degree model texts can enhance the learners’ subsequent writing. The four stages were: (1) writing (pre-test); (2) comparing (treatment); (3) rewriting (immediate post-test); (4) delayed writing (delayed post-test). The findings showed that learners primarily noticed lexical features in the composition and comparison stages. Higher language analytic ability (LAA) learners and guided noticing learners could notice and elicit more information from the model texts. Overall, the use of model texts was effective in improving learners’ writing by providing alternative elements associated with lexis, grammar, content, and organization. In addition, the beneficial effect of model texts on writing could be maintained after 1 week. Some pedagogical implications are put forward to help teachers make better use of model texts to improve learners’ writing. This study also provides new insights into how language analytic ability affects the effectiveness of using models and provides more information on the type of learner most likely to benefit from model texts.

The development of a noble-metal-free cocatalyst is of great significance for boosting photocatalytic H2 evolution performance. Herein, SnSe2 is developed as a cocatalyst to in situ attachment on the surface of sulfur defect rich ZnIn2S4 (Vs-ZIS) via a simple hydrothermal method. Owing to the intimate atomic-level interface and the different work function between Vs-ZIS and SnSe2, a particular Ohmic junction with internal electric field is formed in Vs-ZIS/SnSe2, which facilitates the electrons in Vs-ZIS transfer to SnSe2 and participate in H2 evolution reaction rapidly. Moreover, the abundant S vacancies also benefit the separation of photocarriers in Vs-ZIS/SnSe2. The optimized Vs-ZIS/SnSe2 photocatalyst performs a high H2 evolution rate of 29.34mmol h-1 g-1 under visible light (p >420 nm) and an apparent quantum efficiency of 12.25% at 420 nm. Herein, constructive model on developing effective cocatalyst is afforded, and expediting photocarriers transfer through interfacial modulating. [ABSTRACT FROM AUTHOR]

In the process of food testing, human operation is an important variable affecting the experimental results. In order to reasonably avoid the influence of human subjective operation behavior on the accuracy of detection results, the laboratory information management system was used as the information platform to de-sign a high-throughput laboratory automation pre-treatment system based on the deep integration of mechanical principles, visual analysis, high-speed conduction, intelligent storage and other technical systems. The experimental results showed that the system could shorten the sample circulation cycle, efectvely improve the laboratory biosafety, and meet the requirement of high-throughput procusing of samples.

The wood veneer from Monopetalanthus species was heated under different temperatures (120 °C, 160 °C, 200 °C, and 240 °C) and then laminated as the surface of laminated veneer lumber (LVL). Bending modulus of elasticity (MOE), modulus of rupture (MOR), and impact toughness (IT) of the LVL were tested. The results showed that the failure location became scattered as the surface veneer carbonization temperature was increased and that the failure mode changed from split failure in the control and the 120 °C samples to crack failure in the 160 °C, 200 °C, and 240 °C samples under the bending load. Fiber tearing was visible in all five sample types, where the length of the tearing fibers became shorter with increased surface heating temperature under impact load. The carbonization temperature of surface veneer had a minimal effect on the MOE but a considerable effect on the MOR and IT, and the MOR mainly showed a downtrend. The IT loss decreased as the surface veneer carbonization temperature was increased. [ABSTRACT FROM AUTHOR]

Background: Prenatal alcohol exposure (PAE) is a leading cause of hyperactivity in children. Excitation of dopamine D1 receptor-expressing medium spiny neurons (D1-MSNs) of the dorsomedial striatum (DMS), a brain region that controls voluntary behavior, is known to induce hyperactivity in mice. We therefore hypothesized that PAE-linked hyperactivity was due to persistently altered glutamatergic activity inDMS D1-MSNs. Methods: Female Ai14 tdTomato reporter mice were given access to alcohol in an intermittent access, 2-bottle choice paradigm before pregnancy, and following mating with male D1-Cre mice, through the pregnancy period, and until postnatal day (P) 10. Locomotor activity was tested in juvenile (P21) and adult (P133) offspring, and alcohol-conditioned place preference (CPP) was measured in adult offspring. Glutamatergic activity in DMS D1-MSNs of adult PAE and control mice was measured by slice electrophysiology, followed by measurements of dendritic morphology. Results: Our voluntary maternal alcohol consumption model resulted in increased locomotor activity in juvenile PAE mice, and this hyperactivity was maintained into adulthood. Furthermore, PAE resulted in a higher alcohol-induced CPP in adult offspring. Glutamatergic activity onto DMS D1-MSNs was also enhanced by PAE. Finally, PAE increased dendritic complexity in DMS D1-MSNs in adult offspring. Conclusions: Our model of PAE does result in persistent hyperactivity in offspring. In adult PAE offspring, hyperactivity is accompanied by potentiated glutamatergic strength and afferent connectivity in DMS D1-MSNs, an outcome that is also consistent with the observed increase in alcohol preference in PAE offspring. Consequently, a PAE-sensitive circuit, centered within the D1-MSN, may be linked to behavioral outcomes of PAE. [ABSTRACT FROM AUTHOR]

A highly sensitive nitrite (NO2−) electrochemical sensor is fabricated using glassy carbon electrode modified with Au nanoparticle and grapheme oxide. Briefly, this electrochemical sensor was prepared by drop-coating graphene oxide-chitosan mixed film on the surface of the electrode and then electrodepositing a layer of Au nanoparticle using cyclic voltammetry. The electrochemical behavior of NO2− on the sensor was investigated by cyclic voltammetry and amperometric i-t curve. The results showed that the sensor exhibited better electrocatalytic activity for NO2− in 0.1 mol/L phosphate buffer solution (PBS) (pH 5.0). The oxidation peak current was positively correlated with NO2− concentration in the ranges of 0.9 µM to 18.9 µM. The detection limit was estimated to be 0.3 µM. In addition, the interference of some common ions (e.g., NO3−, CO32−, SO42−, Cl−, Ca2+ and Mg2+) and oxidizable compound including sodium sulfite and ascorbic acid in the detection of nitrite was also studied. The results show that this sensor is more sensitive and selective to NO2−. Therefore, this electrochemical sensor provided an effective tool for the detection of NO2−. [ABSTRACT FROM AUTHOR]

Addiction is thought to be a maladaptive form of learning andmemorycaused by drug-evoked aberrant synaptic plasticity. We previously showed that alcohol facilitates synaptic plasticity in the dorsomedial striatum (DMS), a brain region that drives goal-directed behaviors. The majority of DMS cells are medium spiny neurons (MSNs) that express dopamine D1 receptors (D1Rs) or D2 receptors (D2Rs), which drive "Go" or "No-Go" behaviors, respectively. Here, we report that alcohol induces cell type-specific synaptic and structural plasticity in the DMS. Using mice that express a fluorescence marker to visualize D1R or D2R MSNs, we show that repeated cycles of systemic administration of alcohol or alcohol consumption induces a long-lasting increase in AMPAR activity specifically in DMS D1R but not in D2R MSNs. Importantly, we report that alcohol consumption increases the complexity of dendritic branching and the density of mature mushroom-shaped spines selectively in DMS D1R MSNs. Finally, we found that blockade of D1R but not D2R activity in the DMS attenuates alcohol consumption. Together, these data suggest that alcohol intake produces profound functional and structural plasticity events in a subpopulation of neurons in the DMS that control reinforcement-related learning.

At present, the shortage of agricultural water resources is worsening. In order to reduce the rice irrigation water and improve the utilization of fertilizers so as to achieve the high and stable yielding of rice, this report reviewed the research advances in water and fertilizer coupling, the conception of water and fertilizer coupling and its three kinds of effects (synergy, antagonism, superposition), mechanism of water and fertilizer coupling, effects of water and fertilizer coupling on growth, development, yield and quality of rice and effects of water and fertilizer coupling on utilization rate of nitrogen in rice. In addition, the development prospects of water and fertilizer coupling in China were described. It was proposed that the water and fertilizer coupling mode is an effective measure to achieve the high yield and quality of rice. According to actual demand, referring to the ideas of promoting fertilizer with water and regulating water with fertilizer, reasonable water and fertilizer coupling mode can be established, thereby improving the utilization efficiencies of water and fertilizer. In the premise of saving irrigation water and no increasing fertilization amount, both high yielding and less pollution can be achieved, providing theoretical and technical basis for water-saving agriculture and cultivation and management of rice in future.

Full-bridge (FB)-boost converter is suitable for applications with wide input voltage range and galvanic isolation requirement, and a two-mode phase-shift (PS)-two-edge modulation (TEM) control scheme based on two modulation signals and one carrier can be used to achieve automatic mode shifting and high efficiency. In order to reduce the influence of the input voltage disturbance on the output voltage, the small-signal model of FB-boost converter is built and the input voltage feed-forward (IVFF) functions under different operating modes are derived in this paper. In view of the small-signal and large-signal control laws of the derived IVFF functions, the two-mode PS-TEM control schemes with small-signal and large-signal IVFF compensations are proposed, respectively. Both of them can realize automatic selection of operating modes and the corresponding IVFF compensations, and thus high efficiency and improved input transient response can be guaranteed. Besides, the IVFF function in boost mode is simplified for easy implementation, and the comparisons among the two-mode PS-TEM control schemes with small-signal, large-signal, and without IVFF compensations are presented in this paper. Finally, a 250-500-V input, 360-V output, and 6-kW-rated power prototype demonstrates the effectiveness of the proposed control schemes. [ABSTRACT FROM AUTHOR]

Two-stage single-phase inverters have been widely used as they can achieve voltage matching and galvanic isolation between the input and output. Due to the pulsating output power of the downstream inverter, an ac current at twice the output frequency, which is called second harmonic current (SHC), arises in the input side of the downstream inverter. This SHC will penetrate to the front-end dc-dc converter, leading to reduced conversion efficiency. This paper first analyzes the propagation mechanism of the SHC and load transient response of two-stage single-phase inverters from the viewpoint of output impedance. Then, based on the current mode control and load current feed forward, two control methods to achieve low SHC in the front-end dc-dc converter and fast dynamic performance during load transient are proposed in this paper. Finally, a 2-kW two-stage single-phase inverter prototype has been constructed and tested, and the experimental results are provided to verify the effectiveness of the proposed control methods.

This paper investigates the capacitor-current-feedback active damping for the digitally controlled LCL-type grid-connected inverter. It turns out that proportional feedback of the capacitor current is equivalent to virtual impedance connected in parallel with the filter capacitor due to the computation and pulse width modulation (PWM) delays. The LCL-filter resonance frequency is changed by this virtual impedance. If the actual resonance frequency is higher than one-sixth of the sampling frequency (fs/6), where the virtual impedance contains a negative resistor component, a pair of open-loop unstable poles will be generated. As a result, the LCL-type grid-connected inverter becomes much easier to be unstable if the resonance frequency is moved closer to fs/6 due to the variation of grid impedance. To address this issue, this paper proposes a capacitor-current-feedback active damping with reduced computation delay, which is achieved by shifting the capacitor current sampling instant towards the PWM reference update instant. With this method, the virtual impedance exhibits more like a resistor in a wider frequency range, and the open-loop unstable poles are removed; thus, high robustness against the grid-impedance variation is acquired. Experimental results from a 6-kW prototype confirm the theoretical expectations. [ABSTRACT FROM AUTHOR]

This letter investigates the magnetic integration of the LCL filter in grid-connected inverters. By sharing an ungapped core and arranging the windings properly, the fundamental fluxes generated by the two inductors of an LCL filter cancel out mostly in the common core. Thus, the common core with low flux level can be dramatically reduced. Although the reluctance of the common core can hardly be zero, which implies an inevitable coupling between the integrated inductors, the proposed magnetic integration scheme is still attractive if the cross-section area and magnetic material of the common core are made reasonable. Experimental results from both single-phase and three-phase grid-connected inverters verify the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Supporting services that are related to the core service, such as hospitality and consultation, can enhance the value of a core service. Yet, firms also use supporting services unrelated to the core service to increase consumer satisfaction, delight, and repurchase intentions toward the core service. However, there is little empirical evidence on whether the use of unrelated supporting services has such anticipated effects. This article aims to investigate how unrelated supporting service quality affects consumer delight, satisfaction, and, in turn, repurchase intentions. The results from three experiments reveal that unrelated supporting service quality influences repurchase intentions by affecting consumer delight rather than satisfaction. Thus, unrelated supporting services can serve to delight (but not satisfy) consumers if they are positive, relevant to the consumer segment, and of high quality. In turn, these unrelated supporting services will also influence intentions to repurchase. Consumer delight and unrelated supporting service quality also significantly influence repurchase intentions, but only when the core service quality is high. Unrelated supporting service quality does not influence repurchase intentions if core service quality is low. This suggests the importance of focusing on core service quality first, before trying to delight consumers with extras. [ABSTRACT FROM AUTHOR]

This study aims to investigate the relationships among corporate-brand credibility, product-brand personality, and purchase intention, specifically in China's auto industry. A large-scale survey was conducted in four major Chinese Mainland cities. Beijing, Shanghai, Guangzhou, and Chengdu. A total of 800 questionnaires were distributed for the study. Ultimately, 477 usable cases were collected for a 60 percent response rate. Results reveal that corporate-brand credibility and product-brand personality have direct positive effects on purchase intention. Further- more, corporate-brand credibility acts as a positive moderator in the relationship between product-brand personality and purchase intention. This chapter offers new theoretical insights into the influential factors affecting consumers' purchase intentions by testing the moderating effect of corporate-brand credibility in the relationship between product-brand personality and purchase intention. It further provides useful suggestions to companies on brand credibility and personality issues. [ABSTRACT FROM AUTHOR]

SummaryWe present the case of a young woman who suffered from right cervical lymphadenopathy with associated malaise for 8 weeks. The sonography showed multiple, enlarged lymph nodes in the cervical, submaxillary, and subclavicular chains on the right side. The biopsy of a right cervical lymph node disclosed necrosis, histiocytic accumulation, infiltration with lymphocytes and immunoblasts, and cellular debris, demonstrating histiocytic necrotizing lymphadenitis (HNL). Although the patient had received treatment with dexamethasone for 5 weeks and antibiotic drugs for 6 weeks, the lymphadenopathy and the associated malaise had not improved. For fear of the side-effects caused by dexamethasone and the antibiotic drugs, the patient and her parents asked for treatment with Chinese herbs instead of dexamethasone and antibiotics. With the patient’s and her parents’ consent, the dose of dexamethasone was tapered according to its specifications and Chinese herbs were applied to treat her disease. After 6 weeks of orally administered Chinese herbs both the lymphadenopathy and the associated malaise disappeared. Follow-up by phone 6 months later showed no abnormality. Chinese medicinal herbs, as a natural treatment, can be used as an alternative in treating HNL.Copyright © 2008 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Purpose — The purpose of this paper aims to investigate the relationship between brand personality, country-of-origin (COO) image and purchase intention. Specifically, it is suggested that COO image exerts both main and interaction impact on purchase intention. Design/methodology/approach — A cross-city survey of China's auto industry for the Sino-German Joint Venture's auto brand of Bora was conducted to test hypotheses, predicted on a sample of 1,200 respondents. Another sample for Japan and the Sino-Japanese Joint Venture's Honda auto brand was used for validation. Findings — Results reveal that both brand personality and COO image exert significant positive main effects on purchase intention. Furthermore, COO image is found to be a positive moderator in the relationship between brand personality and purchase intention. Specifically, a positive COO image could enhance brand personality's positive impact on purchase intention, whereas a negative COO image could significantly decrease the positive brand personality effect on purchase intention. Companies with both weak brand personality and a negative COO image achieve a higher purchase intention than those with weak brand personality, yet a positive COO image. Originality/value — This study provides new theoretical insights into factors influencing consumers' purchase decision making by incorporating COO image as a moderator in the relationship between brand personality and purchase intention. It also offers joint ventures useful advice on whether to emphasize brand origin. If a company is weak in both brand personality and COO image, it is better not to emphasize brand origin.

Purpose — The purpose of this study investigates the asymmetric effects of brand origin confusion (BOC) on consumer preference and the purchase of local versus foreign brands in China. Drawing on the general country-of-origin (COO) literature and recent developments in brand-origin studies and the emerging market phenomenon globally, it proposes and test a model of the asymmetric effects of BOC on consumer preference and the purchase of local versus foreign brands in China. This study intends to help to explain from a new angle the decreasing competitiveness of foreign brands in emerging markets, such as China. Design/methodology/approach — The study pretest on nationally distributed brands across seven product categories resulted in a final set of 67 brands: 35 foreign and 32 local. Four hundred respondents evaluated measures related to brand origin, brand awareness, brand value, brand preference, and brand purchases in the previous six months. Hierarchical regression analysis was used in data analysis. Findings — The hypotheses on the asymmetric effects of BOC between local and foreign brands in China were mostly supported. Specifically, the results showed that local brands are likely to be in an advantageous position when there is a high level of BOC. However, as the brand knowledge of consumers increases, the effects of BOC decrease. Originality/value — This study provides evidence of the asymmetric effects of BOC between local and foreign brands and the moderating role of brand knowledge for local brands in China. It fills a gap in the international branding and marketing communication literature, and offers meaningful managerial insights for both local and international companies to formulate effective branding and marketing communication strategies in China and possibly in other emerging markets.

Purpose - Effect size is an important determinant of statistical power. However, very few experimental studies in international marketing (IM) report effect sizes and no meta-analysis work in this regard has been done. The main objective of this paper, therefore, is to quantitatively document effect sizes of experiments in IM and to provide directions for further methodological improvement. Design/methodology/approach - All articles published in the top three marketing journals and the top six IM-related journals during the period 1992-2005 were screened; this yielded 35 experiment-based papers within the domain of IM. For each study, ten methodological characteristics relevant to IM experimental designs were coded. Findings - The 35 studies reported 68 experiments, which produced a total of 1, 074 observations. Results reveal that, on average, for experiments in international business marketing, about 2.89 percent of the variance in a dependent variable (DV) is accounted for by experimental treatments, and a variance of 3.61 percent is shared by the independent and DV for experiments in international consumer marketing. Sampling method, type of subjects, type of design and number of countries are found to have significant influences on effect sizes. Originality/value - This paper provides a quantitative, state-of-the-art review of effect sizes in IM experiments, points out problems such as inappropriate reliance on an overall effect size index, and further offers useful suggestions on how to report and improve effect sizes.

In order to explore the application effect of Yezhiyuan in early hybrid rice, Liangliangyou No.211 and Lingliangyou No.268 were tested in a teaching base in Hunan Agricultural University and Xidu Town, Hengyang County, with Yezhiyuan. The test results showed that the application of photosynthesis synergist in later tillering stage would increase the content of chlorophyll of functional leaf and photosynthetic rate, reduce transpiration rate and enhance yield per unit area. With Yezhiyuan applied, both of photosynthetic rate and chlorophyll content kept higher compared with control group in two experimental sites, and practical yield in Hunan Agricultural University grew 8.54% higher compared with control group, and 10.67% in Hengyang.

The in-plane and out-of-plane band-gap properties of two-dimensional triangular void channel photonic crystals fabricated by femtosecond laser drilling in a solid polymer material were characterized for transverse electric (TE) and transverse magnetic (TM) polarization illumination. For a 24 layer structure stacked in the Γ–M direction, the fundamental stop gap resulted in the suppression of infrared transmission of as much as 96% for TE- and 85% for TM-polarized incident light. The midgap wavelength for the TM polarization was longer by 2.5% than that for the TE polarization. Increasing the angle of incidence for both the in-plane and out-of-plane cases shifted the stop gap to short wavelengths for both TE and TM polarizations. The experimental results allowed for the estimation of the cross section of void channels and the effective refractive index of the polymer after the fabrication. © 2004 American Institute of Physics.
