Based on first-hand materials obtained from field investigations in Malaysia, the results show that: firstly, there are 17 initials in the Leizhou dialect of Malaysia, including the implosives initial and the [f] initial. The pronunciation of Leizhou dialect in China is already rare, some of which are retained in the Leizhou dialect of Malaysia. Its initial consonant is borrowed from local Hua Yu or other Chinese dialects. Secondly, the Leizhou dialect of Malaysia has 46 finals. The pronunciation and timbre of some of its vowels are similar to the Yue dialect of Malaysia [ɐ] main vowel. Thirdly, there are 8 monosyllabic tones in the Leizhou dialect of Malaysia. The pronunciation and tone of some of its characters are similar to the Xia Yin entering tone of Yue dialect of Malaysia.

The tests performed with two hundred and thirty-nine (239) samples from the A-X and B-X drillings help to know their sedimentological and chemostratigraphic characters. In sedimentological term formations are composed of sand, sandstone, limestone, siltstone and argillite that alternate along the drill. In chemostratigraphic term two megasequences (MS1 and MS2) have been identified. A correlation of chemostratigraphic data completed by the lithology results allowed a subdivision of oil wells that shows two main types of deposits environments. First, a proximal marine environment to continental and to Albian marked by a detrital flow deducted from the concentrations evolution of indicator elements of terrigenous material that are K, Mg, and Rb. On the other hand, a deep to shallow marine environment of Cenomanian to Paleocene marked by the presence of predominantly clay sediments and abundant glauconite in the lower Senonian. Nevertheless, there is a transition or intermediate environment that is characterized by the presence of glauconite and detrital flows.
对A-X和B-X钻井的239个样品进行的测试有助于了解其沉积学和化学地层学特征。在沉积学术语中,地层由砂、砂岩、灰岩、粉砂岩和泥质岩组成,它们沿着钻孔交替分布。在化学地层学方面,确定了两个大层序(MS1和MS2)。由岩性结果完成的化学地层资料的对比,使油井的细分显示出两种主要的沉积环境类型。首先,从陆源物质指示元素(K、Mg和Rb)的浓度演化中推断出了以碎屑流为标志的近海相环境。另一方面,塞诺曼—古新世为深—浅海相环境,下塞诺曼世以粘土沉积为主,海绿石丰富。然而,存在一个过渡或中间环境,其特征是海绿石和碎屑流的存在。

123I is the most widely used cyclotron-produced radio-halogen in medical research. In this paper, excitation function formulae for the nuclear reactions of 123I production are introduced. 124Te (p, 2n)123I and 127I (p, 5n)123Xe → 123I nuclear reactions have been studied as a function of the energy of the neutrons. Both two formulae were created using the least squares regression of the experimental cross sections data, which were obtained from the Experimental Nuclear Reaction Data EXFOR Database version of 2023. The proposed formulae were evaluated using two statistical indicators for goodness-of-fit. High agreement was observed between the empirical and experimental results for both nuclear processes.

The purpose of this study was to investigate college students’ use of impoliteness expressions in WeChat diction and what factors influence college students’ use of impoliteness expressions. In-depth interview was used. The chatting records of a large WeChat group with 134 members—Hubin 12 Housings’ 2021 graduate Management group in a comprehensive university in Wuhan in the latest month were analyzed. 10 college students who were members of that WeChat group were interviewed. The interview was related to their inner activities when using impoliteness expressions and what factors could influence their use of impoliteness expressions. The results showed that college students were more likely to use motivated impoliteness, informational impoliteness and strategic impoliteness. College students’ use of impoliteness expressions were influenced by gender, social status and the relationship between the speaker and the hearer. The paper could provide a new study area for researchers. It will attract researchers’ attention on the use of impolite language, especially among different roles of people in society.
本研究的目的是调查大学生在微信用语中不礼貌用语的使用情况,以及影响大学生不礼貌用语使用的因素。采用深度访谈法。分析了武汉某综合性大学的一个134人的大型微信群——湖滨12房2021年研究生管理群最近一个月的聊天记录。我们采访了该微信群的10名大学生。访谈涉及到他们在使用不礼貌表达时的内心活动,以及哪些因素会影响他们使用不礼貌表达。结果表明,大学生更倾向于使用动机性不礼貌、信息性不礼貌和策略性不礼貌。大学生不礼貌用语的使用受性别、社会地位和说话人与听话人关系的影响。本论文可为研究人员提供一个新的研究领域。这将引起研究者对不礼貌语言使用的关注,尤其是不同社会角色之间的不礼貌语言使用。

Bundle recommendation aims to provide users with convenient one-stop solutions by recommending bundles of related items that cater to their diverse needs. However, previous research has neglected the interaction between bundle and item views and relied on simplistic methods for predicting user-bundle relationships. To address this limitation, we propose Hybrid Contrastive Learning for Bundle Recommendation (HCLBR). Our approach integrates unsupervised and supervised contrastive learning to enrich user and bundle representations, promoting diversity. By leveraging interconnected views of user-item and user-bundle nodes, HCLBR enhances representation learning for robust recommendations. Evaluation on four public datasets demonstrates the superior performance of HCLBR over state-of-the-art baselines. Our findings highlight the significance of leveraging contrastive learning and interconnected views in bundle recommendation, providing valuable insights for marketing strategies and recommendation system design.
捆绑推荐的目的是为用户提供方便的一站式解决方案,通过捆绑推荐满足用户多样化需求的相关项目。然而,先前的研究忽略了bundle和item视图之间的交互,并且依赖于简单的方法来预测用户-bundle关系。为了解决这一限制,我们提出了混合对比学习的束推荐(HCLBR)。我们的方法集成了无监督和有监督的对比学习,以丰富用户和捆绑表示,促进多样性。通过利用用户项和用户束节点的互联视图,HCLBR增强了表示学习,以获得健壮的推荐。对四个公共数据集的评估表明,HCLBR优于最先进的基线。我们的研究结果强调了在捆绑推荐中利用对比学习和相互关联的观点的重要性,为营销策略和推荐系统设计提供了有价值的见解。

The role of cocoa systems for climate change mitigation and adaptation has increased substantially because of their capability to trap carbon dioxide from the atmosphere and deposited in the cocoa trees as carbon. Development of aboveground biomass (AGB) models for cocoa plantations is crucial for accurate estimation of carbon stocks in the cocoa systems, however, allometric models for estimating AGB for cocoa plantations remain a challenge for cocoa producing countries in Sub-Saharan Africa especially Ghana. The aim of this study is to develop allometric model that can be used for the estimation of AGB for cocoa plantations in Ghana, as well as West Africa. Destructive sampling was carried out on 110 cocoa trees obtained from the cocoa rehabilitation exercise for the development of the allometric models. Diameter at breast height (D), total tree height (H) and wood density (ρ) were used as predictors to develop seven models. The best model was selected based on coefficient of determination (R2), index of agreement (IA), root mean squared error (RMSE), bias (E%), mean absolute error (MAE) and corrected akaike information criterion (AICC) and percentage relative standard error (PRSE) of the estimated parameters. The selected model, which was the one with the predictors D and ρ, was given as; AGB = 0.7217ρ(D2)0.921. It was compared with the Yuliasmara et al. (2009) cocoa model using equivalence test and paired sample t-test. The two models were found to be equivalent within ±10% of their mean predictions (p < 0.0001) for one-tailed tests for both lower and upper limits, while the paired sample t-test rejected the null hypothesis with mean difference of 14.16 kg between the two models. This study is significant because it has provided a model to estimate AGB for the cocoa plantations in Ghana which is very important for the Ghana Cocoa-Forest REDD+ Programme and also can be used by other West African cocoa producing countries.
可可系统在减缓和适应气候变化方面的作用已经大大增强,因为它们能够从大气中捕获二氧化碳,并以碳的形式沉积在可可树中。开发可可种植园的地上生物量(AGB)模型对于准确估算可可系统中的碳储量至关重要,然而,用于估算可可种植园的地上生物量(AGB)的异速生长模型仍然是撒哈拉以南非洲可可生产国(特别是加纳)面临的一个挑战。本研究的目的是开发可用于估计加纳以及西非可可种植园AGB的异速生长模型。为了建立异速生长模型,对110棵可可树进行了破坏性采样。以胸径(D)、总树高(H)和木材密度(ρ)作为预测因子,建立了7个模型。根据估计参数的决定系数(R2)、一致性指数(IA)、均方根误差(RMSE)、偏倚(E%)、平均绝对误差(MAE)、修正后的赤池信息准则(AICC)和相对标准误差百分比(PRSE)选择最佳模型。所选择的模型,即具有预测因子D和ρ的模型,给出如下;Agb = 0.7217ρ(d2)0.921。采用等价检验和配对样本t检验与Yuliasmara et al.(2009)可可模型进行比较。在单侧检验中,两个模型的下限和上限在平均预测值的±10%以内是相等的(p < 0.0001),而配对样本t检验拒绝了原假设,两个模型之间的平均差为14.16 kg。这项研究具有重要意义,因为它提供了一个模型来估计加纳可可种植园的AGB,这对加纳可可森林REDD+计划非常重要,也可以被其他西非可可生产国使用。

Ancient glass relics are easily weathered by the influence of buried environment, and the internal elements exchange with the environmental elements in large quantities, resulting in changes in their composition ratio. Archaeological research can often detect the component content of glass relics after weathering, but it is difficult to obtain the corresponding component content before weathering. It is necessary to predict the chemical composition of glass relics before weathering in order to accurately identify the type of glass relics and repair them. To solve this problem, this paper proposes a distributed matching strategy, and studies the influence of weathering on the composition content of glass through compositional correlation analysis and linear regression statistical methods, so as to build a prediction model of the composition content of glass relics before weathering. The results show that the composition prediction model of glass cultural relics constructed by the distribution matching strategy has a good prediction ability, which is consistent with the change trend of the composition ratio of linear regression analysis. Moreover, the model is simple and easy to operate, which is convenient for popularization and application, and provides theoretical basis and reference value for further research on the composition and accurate classification of glass cultural relics.
古代玻璃文物易受埋藏环境的影响而风化,内部元素与环境元素大量交换,导致其组成比例发生变化。考古研究往往可以检测到风化后玻璃文物的成分含量,但很难获得风化前相应的成分含量。为了准确识别玻璃文物的类型并进行修复,有必要在风化前对玻璃文物的化学成分进行预测。针对这一问题,本文提出分布式匹配策略,通过成分相关分析和线性回归统计方法研究风化对玻璃成分含量的影响,从而建立风化前玻璃遗迹成分含量的预测模型。结果表明,采用分布匹配策略构建的玻璃文物成分预测模型具有较好的预测能力,与线性回归分析的成分比变化趋势一致。而且该模型简单易操作,便于推广应用,为进一步研究玻璃文物的成分和准确分类提供理论依据和参考价值。

The Science teachers in primary schools are the key group in developing science education, and they play a vital role in realizing the dream of strengthening the country through education. Their professional happiness deserves special attention. Whether this group is happy not only affects their own working conditions and quality of life, but also affects the work vitality of other teachers. Improving the professional happiness of science teachers in primary schools has become an important topic in the construction of teachers’ team in the new period. At present, the intensity of primary school science teachers’ own work is high, their non-own work is increasing, their physical and mental health is difficult to guarantee, and their professional happiness is reduced. The main causes of the problems are poor individual psychological quality, poor school management style and improper social cognitive evaluation. In order to solve this problem, we have explored strategies to improve the professional happiness of science teachers in primary schools through reshaping teachers’ work, democratic management of schools and national policy guarantee.
小学科学教师是开展科学教育的骨干群体,在实现教育强国梦的过程中起着至关重要的作用。他们的职业幸福值得特别关注。这个群体是否快乐,不仅影响到自己的工作条件和生活质量,也影响到其他教师的工作活力。提高小学科学教师的职业幸福感,已成为新时期教师队伍建设的重要课题。目前,小学科学教师的本职工作强度高,非本职工作增多,身心健康难以保障,职业幸福感降低。造成问题的主要原因是个体心理素质差、学校管理作风差和社会认知评价不当。为了解决这一问题,我们从教师工作重塑、学校民主管理和国家政策保障三个方面探索了提高小学科学教师职业幸福感的策略。
