Abstract The constant development of computer technology has greatly facilitated our life. In the past, the agricultural products trade and agricultural products business model were an offline development, through face-to-face transactions. However, with the continuous application of Internet technology, we also have a new exploration on the e-commerce path of agricultural products. The fuzzy neural network algorithm was used to study the electronic commerce path of agricultural products and helped us to carry out the exploration computation of the electronic commerce path of agricultural products. And good calculation results have been obtained. Through our testing of the fuzzy neural network algorithm,… More >

Abstract Low-power wide area network (LPWAN) has developed rapidly in recent years and is widely used in various Internet of Things (IoT) services. In order to reduce cost and power consumption, wide coverage, LPWAN tends to use simple channel access control protocols, such as the Aloha protocol. This protocol is simple with poor extension capability. In high-density environment, Aloha protocol will lead to low channel utilization, prolonged access and high conflict probability. Therefore, in order to solve the above problems, we propose an enhanced channel access control mechanism based on the existing LoRaWAN protocol, that is, a dynamic listening backoff mechanism.… More >

Abstract Objective: To get an impression of the quality of life (QOL) and sexual well-being in the Fontan population, and to generate hypotheses for future research.
Methods: For this cross-sectional pilot study, questionnaires regarding health-related QOL, sexual function and fertility/pregnancy were completed by 21 patients with a Fontan circulation >16 years old, followed at the University Medical Center Groningen, the Netherlands. Semi-structured qualitative interviews were conducted in 8 patients.
Results: Fontan patients scored significantly lower on general health than their healthy peers (t (19)=-3.0, P = .008), whereas their scores on other QOL domains and sexual well-being were comparable to normal… More >

Abstract Objective: This study explores the role of the Notch3‐HES5 signal pathway in mono‐ crotaline‐induced pulmonary hypertension (PH) using rat models.
Method: Sprague Dawley rats (n = 45) were randomly grouped into normal group, control group, and model group. Rats in the model group were used to establish the PH rat model. Four weeks after model establishment, right catheterization was used to measure the mean pulmonary arterial pressure (mPAP) and right ventricular sys‐ tolic pressure (RVSP) to analyze hemodynamic changes. The severity of PH was as‐ sessed by the right ventricular hypertrophy index (RVHI) and percentage of media thickness (MT%). The… More >

Abstract In the boundaryless career era, employees tend to focus on their own needs and what they can obtain from jobs to make wise career choices and achieve a high level of career satisfaction. Using a sample of 230 Chinese employees, this study investigated the mediating effect of demands-abilities fit and needs-supplies fit in the relationship between career exploration and career satisfaction and compared the mediating effects of these two types of person-job fit. This study found that: 1) employees could achieve a higher level of career satisfaction by conducting more career exploration behaviors; 2) both demands-abilities fit and needs-supplies fit… More >

Abstract Based on social cognitive career theory, this study examined career success criteria clarity and career decision-making self-efficacy as mediators in the relationship between career exploration and affective well-being. Data were collected from 475 emerging adults in their early career stages in China. The results showed that both career success criteria clarity and career decision-making self-efficacy mediated the relationship between career exploration and affective well-being. Career decision-making self-efficacy exhibited a stronger mediating effect on this relationship than career success criteria clarity. These findings reveal some important mechanisms underlying the role of career exploration in generating affective well-being and contribute to the… More >

Abstract Based on basic psychological needs theory of self-determination theory, this study investigates the interaction effect of proactive personality and career exploration on well-being for graduating students during school-to-work transition. Using a survey sample of 216 graduating students in China, we found that: 1) Proactive personality had a positive relationship with well-being. 2) Career decision-making self-efficacy mediated the relationship between proactive personality and well-being. 3) Career exploration negatively moderated the relationship between proactive personality and career decision-making selfefficacy. The relationship between proactive personality and career decisionmaking self-efficacy was stronger when career exploration was lower. 4) Career exploration also negatively moderated the… More >

Abstract A spectrophotometric investigation of oxidation of chondroitin-4-sulfate (CS) as a sustainable and biodegradable sulfated macromolecule by oxyanion permanganate ion as multi-equivalent oxidant in acid perchlorate solutions at a constant ionic strength of 2.0 mol dm^-3 has been studied. The experimental results on the influence of the concentration of the reactants the reaction rates revealed first-order dependence in MnO₄^– , fractional second-order in [CS] and fractional first-order with respect to the hydrogen ion concentration. The hydrogen acid concentration dependence of the rate constants indicated that the oxidation rates were increased with increasing the acid concentration which means that the oxidation reaction… More >

Abstract The success of sexual plant reproduction is directly influenced by specific interactions between the pollen and pistil. Light, fluorescence and scanning electron microscopy techniques were used to evaluate the steps of pollination in sour passion fruit plants (Passiflora edulis Sims). In the compatible interaction, pollen tubes grow through stigma projections towards the ovary. The pollen grain surface was found to be spheroidal and to consist of heteroreticulate exine with six colpi. Furthermore, analysis in vivo of pollenpistil interactions indicated that stigmas of flowers 24 hours before anthesis are unable to discriminate compatible (genetically unrelated) and incompatible (genetically related) pollen grains.… More >

Abstract Jubaea chilensis (Molina) Baill. (Chilean palm) is an endemic species in Chile. It has been classified as a vulnerable species because of the reduction and the fragmentation of its population numbers, the exploitation of the palms for the production of syrup, the indiscriminate harvest of seed for human consumption, and the reduction of the accompanying native vegetation cover. The southernmost limit of its natural distribution is located in Palmas de Tapihue (Pencahue, Maule region). The objective of this study was to benchmark the conservation status of this population and its accompanying vegetation. The population of J. chilensis in Tapihue was… More >
