Ingroup sources enhance associative inference
Authors: Boeltzig Marius , Johansson Mikael , Bramão Inês
Published: December 2023

Episodic memory encompasses flexible processes that enable us to create and update knowledge by making novel inferences across overlapping but distinct events. Here we examined whether an ingroup source enhances the capacity to draw such inferences. In three studies with US-American samples (NStudy1 = 53, NStudy2 = 68, NStudy3 = 68), we investigated the ability to make indirect associations, inferable from overlapping events, presented by ingroup or outgroup sources. Participants were better at making inferences based on events presented by ingroup compared to outgroup sources (Studies 1 and 3). When the sources did not form a team, the effect was not replicated (Study 2). Furthermore, we show that this ingroup advantage may be linked to differing source monitoring resources allocated to ingroup and outgroup sources. Altogether, our findings demonstrate that inferential processes are facilitated for ingroup information, potentially contributing to spreading biased information from ingroup sources into expanding knowledge networks, ultimately maintaining and strengthening polarized beliefs.

Haematopoietic development and HSC formation in vitro: promise and limitations of gastruloid models
Authors: Dijkhuis Liza , Johns Ayona , Ragusa Denise , van den Brink Susanne C. , Pina Cristina
Published: December 2023

Haematopoietic stem cells (HSCs) are the most extensively studied adult stem cells. Yet, six decades after their first description, reproducible and translatable generation of HSC in vitro remains an unmet challenge. HSC production in vitro is confounded by the multi-stage nature of blood production during development. Specification of HSC is a late event in embryonic blood production and depends on physical and chemical cues which remain incompletely characterised. The precise molecular composition of the HSC themselves is incompletely understood, limiting approaches to track their origin in situ in the appropriate cellular, chemical and mechanical context. Embryonic material at the point of HSC emergence is limiting, highlighting the need for an in vitro model of embryonic haematopoietic development in which current knowledge gaps can be addressed and exploited to enable HSC production. Gastruloids are pluripotent stem cell-derived 3-dimensional (3D) cellular aggregates which recapitulate developmental events in gastrulation and early organogenesis with spatial and temporal precision. Gastruloids self-organise multi-tissue structures upon minimal and controlled external cues, and are amenable to live imaging, screening, scaling and physicochemical manipulation to understand and translate tissue formation. In this review, we consider the haematopoietic potential of gastruloids and review early strategies to enhance blood progenitor and HSC production. We highlight possible strategies to achieve HSC production from gastruloids, and discuss the potential of gastruloid systems in illuminating current knowledge gaps in HSC specification.

Authors: Ma Shuangbin , Huang FeiTing , Chen Jinxin , Tong Weiyun , Wang Lin , Xu Qiping
Published: December 2023

The power generation of the photovoltaic plant is related to the cleanliness of the photovoltaic modules. The accumulation of natural dust is the main source of pollution, which is affected by human activities and meteorological factors such as temperature, humidity, wind speed, and rainfall concentration in the current region. On the basis of particle swarm optimization (PSO) and the least‐squares support vector machine (LSSVM), the density of dust on photovoltaic modules was estimated. The authors proposed that the inertia weight decreased as a concave function to improve the efficiency of optimization and let the two positive constants change dynamically to improve convergence performance. The dust accumulation prediction model was established considering natural rainfall and the authors obtained the attenuation rate of the photovoltaic power output. Finally, the experiments in Hangzhou showed that the model can predict the density of accumulated dust quickly, which provides a theory for predicting PV power generation and managing the cleaning frequency.

Authors: Zhao Haiqi , Zhu Yongqing , Lu Kaicheng , Li Qingsheng , Li Zhen , Dong Shufeng
Published: December 2023

Edge‐side services provide new ideas for microgrid operational control, but as the microgrid control structure becomes increasingly large, the cost of configuring edge‐side services also grows. In this context, it is necessary to find a modelling approach that can unify the mathematical models involved in microgrid control systems. First, a microgrid control structure with edge‐computing services based on hybrid control theory is proposed, which can exploit the hybrid characteristics of the microgrid control and reduce the amounts of communication using event‐triggered technology. Then, a hybrid control modelling method based on activity‐on‐edge networks is proposed, along with a standardised control strategy configuration method. The texts entered by the configurator can be parsed in an intuitive way. Complex control strategies can be configured with low‐code input while improving the reliability of the strategies. Finally, a distributed control strategy for DC microgrids was studied and modelled using the hybrid control modelling approach based on activity‐on‐edge networks. The superiority of edge‐computing services based on hybrid control theory and event‐triggered technology in reducing communication and improving control in real time is demonstrated through the case study.
A modified control strategy for LCC with IGCT‐based full‐bridge submodules to solve the commutation failure issues
Authors: Liu Yindi , Zeng Xiangjun , Luo Yiping , Qu Haitao
Published: December 2023

To solve the commutation failure (CF) issues in high voltage direct current (HVDC) transmission systems based on line commutated converter (LCC), this paper proposes a hybrid solution combining the LCC inverter with the continuously controlled IGCT‐based full‐bridge submodules (FBSMs). The scheme can provide the LCC inverter with an additional commutation area, and compensate for the phase‐shift of the grid voltage under faults. Therefore, it shows better CF resistance than the existing scheme. The characteristics of the proposed hybrid converter are modelled and analyzed in both normal and fault conditions. Then a decoupling control strategy is presented for it. With the ability to counteract negative‐sequence grid voltage, the strategy brings good voltage stability to the dc transmission. And when the grid fault occurs, it can switch to suppress CF by rapidly increasing the output voltage of the FBSMs and applying commutation failure prevention (CFPREV) control to the LCC. As a result, the CF issues can be maximally solved with a smaller number of FBSMs than the existing scheme. Simulations in PSCAD verify the effectiveness of the strategy. Furtherly, an experimental platform is built to show the capacity of the proposed scheme to solve the CF issues.

Published: December 2023

The asymmetric calibration method is a very interesting technology for differential output probes. It has been proven that the asymmetric calibration method (ACM) can broaden the application scenarios of the electromagnetic field dual probe. However, ACM is not verified on a back‐to‐back double‐loop differential magnetic field probing system. This paper calibrates a back‐to‐back double‐loop differential magnetic field probing system by inserting a connector for creating an asymmetry using ACM. The calibration results show that ACM can be used to calibrate an asymmetric back‐to‐back double‐loop differential magnetic field probing system. The calibration results are further verified by measuring the standing wave magnetic field, and the verification results show that the asymmetric calibration method is effective in eliminating the asymmetry of the back‐to‐back double‐loop differential magnetic field probing system and the work frequency band reaches up to 12 GHz.
Search for duplicates of showers in the IAU MDC database
Authors: Jopek T. J. , Neslušan L. , Rudawska R. , Hajduková M.
Published: December 2023

Context. The meteor shower database of the IAU Meteor Data Center (MDC) is used by the whole community of meteor astronomers. Observers submit both new and known meteor shower parameters to the MDC. Two types of problems may arise during the submission process: If a new observation of an already-known meteor shower is submitted as the discovery of a new shower, a duplicate shower will appear in the MDC. If the submission of a new set of parameters for an existing shower is incorrect, a false duplicate of a known meteor shower will appear in the MDC. The MDC database contains such duplicates and false duplicates, so it is desirable to detect them among the streams already in the database and those delivered to the database as new streams.

Aims. We aim to develop a method for objective detection of duplicates among meteor showers and to apply it to the MDC. The method will also enable us to verify whether various sets of parameters of the same shower are compatible and thus reveal the false duplicates.

Methods. We suggest two methods based on cluster analyses and two similarity functions among geocentric and heliocentric shower parameters collected in the MDC.

Results. We obtained a number of results of varying significance. Seven new showers represented by two or more parameter sets were discovered, revealing the duplicates we searched for. We found full agreement between our results and those reported in the MDC database for 30 showers. The multiple sets of parameters defining these showers are correct since they were identified as duplicates. For 20 showers, the same duplicates as given in the MDC were found only by one method. We found 27 showers for which the number of parameter sets found by both methods is close to the corresponding number in the MDC database. However, we found 56 showers listed in the MDC by more than one set of parameters for which no duplicates were found by either of the applied methods. These showers have false duplicates among their sets of parameters.

Conclusions. The obtained results confirm the effectiveness of the proposed approach of identifying duplicates. We have shown that in order to detect and verify duplicate meteor showers, it is possible to apply the objective proposal instead of the subjective approach used so far. We consider the identification of 83 problematic cases in the MDC database, among which at least some duplicates were misclassified, to be a particularly important result. The correction of these cases will significantly improve the content of the MDC database.
Co-moving groups around massive stars in the nuclear stellar disk
Authors: Martínez-Arranz Á. , Schödel R. , Nogueras-Lara F. , Hosek M. W. , Najarro F.
Published: December 2023

Context. Over the last ∼30 Myr, the nuclear stellar disk in the Galactic center has been the most prolific star-forming region of the Milky Way when averaged by volume. Remarkably, the combined mass of the only three clusters present today in the nuclear stellar disk adds up to only ∼10% of the total expected mass of young stars formed in this period. Several causes could explain this apparent absence of clusters and stellar associations. The stellar density in the area is so high that only the most massive clusters would be detectable against the dense background of stars. The extreme tidal forces reigning in the Galactic center could dissolve even the most massive of the clusters in just a few megayears. Close encounters with one of the massive molecular clouds, which are abundant in the nuclear stellar disk, can also rapidly make any massive cluster or stellar association dissolve beyond recognition. However, traces of some dissolving young clusters and associations could still be detectable as co-moving groups.

Aims. It is our aim to identify so far unknown clusters or groups of young stars in the Galactic center. We focus our search on known, spectroscopically identified massive young stars to see whether their presence can pinpoint such structures.

Methods. We created an algorithm to detect over-densities in the 5D space spanned by proper motions, positions on the plane of the sky, and line-of-sight distances, using reddening as a proxy for the distances. Since co-moving groups must be young in this environment, proper motions provide a good means to search for young stars in the Galactic center. As such, we combined publicly available data from three different surveys of the Galactic center, covering an area of ∼160 arcmin2 on the nuclear stellar disk.

Results. We find four co-moving groups around massive stars, two of which are very close in position and velocity to the Arches’ most likely orbit.

Conclusions. These co-moving groups are strong candidates to be clusters or associations of recently formed stars, showing that not all the apparently isolated massive stars are run-away former members of any of the three known clusters in the Galactic center or simply isolated massive stars. Our simulations show that these groups or clusters may dissolve beyond our limits of detection in less than ∼6 Myr.

Published: December 2023

The emergence of paraffin-coated rice in China, aimed at enhancing its market appeal and achieving a translucent appearance, has given rise to a significant global food safety concern. This situation poses substantial health risks to consumers. Hyperspectral analysis, recognized as a powerful and nondestructive technique for assessing food quality and safety, offers a potential solution. This study conducted a comprehensive investigation using Visible-Near Infrared (VIS-NIR) hyperspectral imaging systems operating within the 400-1000 nm range to identify paraffin-contaminated rice. Various rice varieties from diverse regions were obtained and intentionally tainted with varying levels of paraffin. Imaged samples were further preprocessed for spectral data extraction from individual rice seeds’ regions of interest (ROI). The dataset encompassed 3000 spectral records obtained from both non-contaminated and contaminated samples. The obtained spectral data were employed to develop partial least squares discriminant analysis (PLS-DA) and principal component linear discriminant analysis. The primary goal was to discriminate between contaminated and non-contaminated rice samples effectively. Notably, the results indicated that PLS-DA consistently achieved an accuracy exceeding 94% across various preprocessing techniques. Overall, this study showcased the potential of combining hyperspectral imaging with chemometrics to detect paraffin-contaminated rice seeds, providing a valuable contribution to food safety assessment in the industry.

North Sumatra Province is an area with considerable agricultural potential in the Sumatra region. Analysis of the carrying capacity of agricultural land in North Sumatra in 2020 is very important to do in order to determine the carrying capacity of agricultural land in North Sumatra in meeting the food needs of its people. The purpose of this paper is to calculate and present the results of the analysis of the carrying capacity of agricultural land in North Sumatra Province. The data needed in this study is secondary data obtained from several journals and publications from related agencies, such as the Central Statistics Agency (BPS) of North Sumatra Province. The results showed that overall the carrying capacity of North Sumatra’s land was classified as low. The low carrying capacity of rice farming land in North Sumatra is caused by increasing population growth and the quality of agricultural land which continues to decline so that the production of rice plants cannot meet the maximum food needs of the community. Therefore, it is necessary to make efforts to increase the carrying capacity of rice farming land in this area, for example by reducing the population and improving the quality of agricultural land resources.

Published: December 2023

Tropical rainforests in Indonesia is currently managed by Intensive Forest Management System (IFMS), characterized by selective timber harvesting and intensive rehabilitation to enrich standing stock. This study conducted quantitative evaluations on catchment scale impacts of IFMS during each selective logging (SL) and intensive rehabilitation (IR) stage. SS concentrations were measured in three headwater catchments located in tropical rainforests of the Bukit Baka Experimental Catchments, Central Kalimantan, Indonesia. While no forestry operation was conducted in catchment A, operations based on IFMS were conducted in catchments B and C. A combination among the great surface disturbance by skid trails, large tree extraction ratio, and high slope angle of catchment B resulted in the greatest SS. During the post-IR period, SS concentration of catchment B did not show decreases in comparison with that during the post-SL period. In catchment C, increases in SS concentration were observed during the post-IR period. Thus, this study indicated that IR of IFMS was not effective to decrease SS concentration in the initial stage of the post operation period, but the modified intensive rehabilitation with considering the contour and topography potentially significant to control erosion.

Published: December 2023

Dragon fruit is a promising export commodity for Indonesia. But its short shelf-life is a big challenge for an international shipping by sea. This study aims to prolong the dragon fruit shelf life by implementing gas absorbent based Modified Atmosphere Packaging (MAP) in combination with cold storage. This technique decreases the fruit physiological processes by lowering O2 concentration (%) inside the MAP. The selected dragon fruit was packed with gas absorbent-based MAP with different O2 absorber capacities (30 cc; 60 cc; and 120 cc) and plastic types (biodegradable plastic and LDPE). Each treatment was also varied with the use of H2O absorbent and perforation. Then, the dragon fruit in MAP was stored at 5°C and 90% RH for 6 weeks as shipping simulation. After storage, the dragon fruit was transferred to 27°C room temperature without MAP. The results showed that the application of gas absorbent-based MAP, additional treatments, and low temperature were generally able to maintain the quality of dragon fruit up to 6 weeks in cold storage. However, dragon fruit developed signs of chilling injury, increased water loss, increased weight loss, decreased hardness, skin damage, fin withering, and mold growth after transfer at 27°C room temperature without MAP.

Published: December 2023

This study identified the handling of dry fermented cocoa bean production, analyzed the level of cocoa supply chain (SC) performance in Patuk, and developed recommendations for poor performance to improve SC performance. In this study, environmentally friendly handling was carried out by observing the SC and processing process, and SC performance was measured based on the Supply Chain Operations Reference (SCOR) model in the scope of reliability, responsiveness, and agility supported by the 2.2 Analytical Hierarchy Process (AHP) weighting method using pairwise comparison. The result of this study indicates that sustainable practices from the seeding, nurturing, harvesting, and shipping stages are easier to implement due to the small scale and proximity to residential areas and processing units. Cocoa SC performance in Patuk is divided into 3 parts, namely for farmer performance (79.79), collective traders (70.23), and processing industry (83.29). Improvements that can be made to improve the performance of the SC are by increasing plant maintenance, recording production, and making contracts. The benefits of this study are to encourage the adoption of environmentally friendly cocoa cultivation and processing practices, provide information on SC factors on SC performance, and provide recommendations for performance improvement.
Factors influencing radiologic technologists’ commitment to radiation protective equipment utilization in fluoroscopy units: an analysis using the health belief model scale
Authors: Shubayr N.
Published: December 2023

Objective: This study aimed to assess the perceptions of radiologic technologists towards the use of radiation protective equipment (RPE) in fluoroscopy units and to identify the Health Belief Model constructs, “perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy”, that predict RPE utilization among radiologic technologists.

Methods: A cross-sectional observational study was conducted among 228 radiologic technologists in Saudi Arabia. Data were collected using a self-administered questionnaire that included socio-demographic characteristics, frequency of RPE utilization, and the Health Belief Model. Logistic regression was used to identify the predictors of RPE utilization.

Results: The findings indicate that 63% of radiologic technologists reported always being committed to using RPE, while 37% reported not fully committed. Perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy showed significant associations with RPE utilization between the two groups of radiologic technologists: those who always use RPE and those who are not fully committed (p < 0.05). Logistic regression showed that perceived benefits were a significant predictor of RPE utilization (AOR = 0.20, 95% CI: 0.60–0.67, p = 0.009), and type of hospital was also a significant predictor (AOR=0.09, 95% CI: 0.1–0.97, p = 0.047).

Conclusion: The study highlights the need for interventions to improve the consistent use of RPE among radiologic technologists in fluoroscopy units. Emphasizing the importance of RPE usage, addressing barriers, and providing adequate cues to action can help enhance radiologic technologists’ commitment to using RPE and reduce radiation exposure risks. Tailoring interventions to the specific hospital setting and considering the perceived benefits of using RPE are crucial for promoting a culture of safety and accountability in different healthcare settings.

Utilizing a sample from Beijing Sport University, the research employed a questionnaire-based approach, targeting both sports and non-sports students. A total of 800 questionnaires were distributed, with 765 valid responses received. The participants were divided into four sports categories: basketball, football (soccer), tennis, and swimming. Two of these sports were team-based (basketball and football), while the other two were individual sports. The intensity of all exercises was moderate, and the study spanned over a period of two months. Psychological well-being was assessed using the Symptom Self-Assessment Scale (SCL-90), a reliable and valid instrument. Preliminary findings suggest that moderate exercise, especially within a duration of 30-60 minutes, significantly enhances psychological health. However, excessive exercise beyond 60 minutes showed a gradual decline in mental health scores. Gender differences were also observed, with male students exhibiting higher exercise intensity than their female counterparts. The study underscores the importance of moderate physical activity for mental health and calls for personalized sports guidance based on gender preferences.

Authors: Song Chunxia , Wang Gang
Published: December 2023

The essence of human is the organic unity of human’s ‘class’ characteristics, group attributes and individual attributes. Investigating people from the perspective of human’s ‘class’ characteristics is not only a deep questioning of human nature and destiny, but also an analysis of the essential differences between people, which is the fundamental purpose of studying human nature and the key to exploring the relationship between individual and community. Therefore, this paper emphasizes the interdependence and mutual influence between the individual and the community from the "class" characteristics of human beings, analyzes the tension between the individual and the community, and discusses how to realize the reconciliation between the two, so as to establish a more harmonious symbiotic relationship between the individual and the community.

Study on Administrative Regulations Governing the Disciplinary Authority of Teachers
Authors: Shi Jiayun
Published: December 2023

The disciplinary authority of teachers, as a form of power, often leads to instances of abuse. Such situations have adverse effects on the physical and psychological well-being of students, especially at various educational stages, including kindergarten and compulsory education. While Chinese civil and criminal laws provide some regulation in this regard, there still exists a grey area that is difficult to address. Administrative law, due to its inherent characteristics, is suitable for regulating this grey area. However, in the current regulatory landscape, there are significant issues concerning rules, supervision, remedies, and penalties. There is a need to further refine the rules governing disciplinary management, improve monitoring methods and mechanisms, enhance the avenues for redress for students subjected to discipline, clarify the methods and severity of penalties, in order to ensure that the relevant regulations and regulatory systems effectively safeguard students’ right to education.
