To solve a state transfer matrix using a Markov model, an improved genetic algorithm approach is proposed. A Markov prediction model is employed to study structures in the SME technical efficiency and scale gains calculation method. The obtained results are compared to the data shown in the China Statistical Yearbooks. It is found that our proposed genetic algorithm approach provides references for optimizing an agriculture SME industrial structure and hence improves the prediction precision.

Background: Cultivation of medicinal crops, which synthesize hundreds of substances for curative functions, was focused on the synthesis of secondary metabolites rather than biomass accumulation. Nutrition is an important restrict factor for plant growth and secondary metabolites, but little attention has been given to the plasticity of nutrient uptake and secondary metabolites synthesis response to soil nitrogen (N) change. Methods: Two year-field experiments of Sanqi (Panax notoginseng), which can synthesize a high level of saponin in cells, were conducted to study the effects of N application on the temporal dynamics of biomass, nutrient absorption, root architecture and the relationships between these parameters and saponin synthesis. Results: Increasing N fertilizer rates could improve the dry matter yields and nutrient absorption ability through increasing the maximum daily growth (or nutrient uptake) rate. Under suitable N level (225 kg/ha N), Sanqi restricted the root length and surface and enhanced the root diameter and N uptake rate per root length (NURI) to promote nutrient absorption, but the opposite status of Sanqi root architecture and NURI was found when soil N was deficient. Furthermore, increasing N rates could promote the accumulation of saponin in roots through improving the NURI, which showed a significant positive relationship with the content of saponin in the taproots. Conclusion: Appropriate N fertilizer rates could optimize both root architecture and nutrient uptake efficiency, then promote both the accumulation of dry matter and the synthesis of saponins.

Background/Aims Straight leg raise (SLR) can be utilized to evaluate the integrity of the esophagogastric junction during high-resolution manometry (HRM). We aim to assess the value of transient hiatal separation during SLR in symptomatic reflux patients. Methods Consecutive reflux patients undergoing esophageal HRM and pH monitoring were included. Transient hiatal separation was defined by a ≥ 1 cm separation between the lower esophageal sphincter and crural diaphragm during SLR. We compared esophageal motor patterns and reflux monitoring parameters between patients with normal, transiently abnormal and consistently abnormal esophagogastric junction morphology during SLR. Results Of 85 (56.3% female, mean age: 46.7 ± 12.3 years) completed SLR, esophagogastric junction morphology was normal in 31 (36.5%), transient hiatal separation in 19 (22.3%), and consistently hiatal hernia in 35 (41.2%). The values of total acid exposure time (P = 0.016), longest acid reflux episodes (P = 0.024), and DeMeester scores (P = 0.016) were higher in hiatal hernia compared to patients with non-transient hiatal separation, but there were no differences between those with and without transient hiatal separation. Within ineffective esophageal motility, the presence of transient hiatal separation during SLR significantly associated with a higher total acid exposure time (P = 0.014), higher DeMeester scores (P = 0.019), higher total acid reflux events (P = 0.037), and higher longest acid reflux episodes (P = 0.006). Conclusion Our work suggests that SLR may have value as a provocative test during HRM, and future outcome studies are warranted to elucidate the clinical relevance of motor abnormalities depicted from SLR.

Starch-based biomass composites were prepared with starch and plant fiber. In order to improve the properties of the compos ites, oxidized starches (OS) were prepared using hydroxyl peroxide as oxidizer, then glycerol was added into OS as plasticizer to produce thermoplastic oxidized starches (TPOS). Crystal structure, hydrogen bonds of TPOS were researched to gain comprehensive views on the mechanism of the property differences between the starch-based composites with native starch, OS and TPOS. The changes of crystal structure were analyzed by X-ray diffraction analysis. Starch intermolecular hydroxyl changes were investigated using the method of infrared spectrum analysis. It was found that the new hydrogen bonds were formed between the plasticizer, oxidizer and starch, and the starch intermolecular bonding force was weakened. The structure of starch crystallization was destructed in TPOS. Differential scanning calorimetry showed that cross reaction with oxidization and plasticization changed the crystal structure, glass transition process was not observed in TPOS. The tensile and compressive strengths of composite based on TPOS were improved greatly and mechanical properties were not weakened obviously with water content increased. All the results indicated that TPOS could improve the properties of starch-based composites.

Background/AimsThis study aims to evaluate the effects of acute codeine administration on primary and secondary esophageal peristalsis in patients with ineffective esophageal motility (IEM). MethodsEighteen IEM patients (8 women; mean age 37.8 years, range 23-64 years) were enrolled in the study. The patients underwent high-resolution manometry exams, consisting of 10 single wet swallows, multiple rapid swallows, and ten 20 mL rapid air injections to trigger secondary peristalsis. All participants completed 2 separate sessions, including acute administration of codeine (60 mg) and placebo, in a randomized order. ResultsCodeine significantly increased the distal contractile integral (566 ± 81 mmHg∙s∙cm vs 247 ± 36 mmHg∙s∙cm, P = 0.001) and shortened distal latency (5.7 ± 0.2 seconds vs 6.5 ± 0.1 seconds, P < 0.001) for primary peristalsis compared with these parameters after placebo treatment. The mean total break length decreased significantly after codeine treatment compared with the length after placebo (P = 0.003). Codeine significantly increased esophagogastric junction-contractile integral (P = 0.028) but did not change the 4-second integrated relaxation pressure (P = 0.794). Codeine significantly decreased the frequency of weak (P = 0.039) and failed contractions (P = 0.009), resulting in increased frequency of normal primary peristalsis (P < 0.136). No significant differences in the ratio of impaired multiple rapid swallows inhibition and parameters of secondary peristalsis were detected. ConclusionsIn IEM patients, acute administration of codeine increases contraction vigor and reduces distal latency of primary esophageal peristalsis, but has no effect on secondary peristalsis. Future studies are required to further elucidate clinical relevance of these findings, especially in the setting of gastroesophageal reflux disease with IEM.
Interpreting and Analyzing the Character 得 in Mencius : Insights from Four Commentaries
Chuan-wei ZHANG 세계한자학회 2023 世界漢字硏究 Vol.6 No.2
According to traditional philological materials such as Shuowen Jiezi and oracle bone inscriptions, the original meaning of the character 得 is “get”. This article takes the Book of Mencius as closed materials, exhaustively categorizing all entries of 得 in Mencius, totaling 114 examples. Then we analyze semantic content and grammatical features references to the four commentaries from Zhao Qi , Sun Shi, Zhu Xi, Jiao Xun. We find that all examples of 得 are used as verbs, but there are 12 examples where it is used as a delexical verb, exemplifies the gradual trend of semantic attenuation of 得. After conducting linguistic analysis of the character 得, we explore its manifestation of the philosophical ideas in Mencius, including aspects of personal cultivation, interpersonal relationships, and governance wisdom. Through the interaction of language and cultural analysis, we further deepen our study of the language theory and ancient classics culture.
