Abstract： Large quantities of suboptimal food, which contain defects but are perfectly safe for consumption, are wasted. Commercializing suboptimal food has become an important strategy in reducing food waste. However, experimental outcomes regarding the effectiveness of marketing intervention strategies for suboptimal food have exhibited inconsistency. This study adopted a meta-analysis approach to review empirical research on marketing intervention strategies for suboptimal food. It examined the effectiveness of cognitive-oriented and affective-oriented marketing intervention strategies in influencing consumer evaluations and purchase intentions towards suboptimal food. Additionally, the study aimed to identify variables that may impact the effectiveness of these strategies. In total, 32 relevant primary studies were included, comprising 94 effect sizes from 57 independent samples. The study showed that both cognitive-oriented and affective-oriented marketing intervention strategies can effectively improve consumers’ positive evaluations and willingness to purchase suboptimal food with a moderate level of efficacy. Moreover, affective-oriented strategies demonstrated a better intervention effect compared to cognitive-oriented ones. Factors such as suboptimal food characteristics, marketing features, and customer characteristics were found to moderate the effectiveness of these interventions. This study provided valuable insights for food-related enterprises and food policy makers regarding the effectiveness of marketing interventions for suboptimal food.

Abstract： Psychological and brain science study human behavior and the human brain by study volunteers who participate these studies. Given the mind and behavior of participants influenced by their own biological and social factors, the generalizability of findings in these fields largely depends on the representativeness of samples. However, the representativeness of samples in psychological and brain science has long been criticized as WEIRD (Western, Educated, Industrialized, Rich, and Democratic). In recent years, several meta-researches have surveyed the representativeness of samples in published studies across different subfields, but the overall understanding of sample representativeness in psychological and brain science is lacking. In this review, we analyze these meta-researches to provide a more comprehensive perspective on the current state of sample representativeness in the field.
Two major issues were found in these meta-researches. First, much important sample information was never reported in the published studies. Most psychological and brain science studies reported participants’ gender, age, and country, while participants’ race/ethnicity, education level, and socioeconomic status were less commonly reported. Other important demographic variables, such as rural/urban, were reported completely ignored. And from a temporal perspective, the reporting of these demographic variables has increased only slightly in recent years compared to the past. The current situation of neglect in reporting demographic information has not fundamentally changed.
Second, based on the reported information, the current sample in the field is far from being representative of the world population: most participants are young, highly educated Caucasian females in Western countries; middle-aged and older, less educated, disadvantaged people in and outside Western countries are less likely to be studied. In terms of countries, African, Latin American, and Middle Eastern countries appear fewer in psychological and brain science research.
These two issues may be due to the following reasons: convenience sampling as the main sampling method; Western researchers dominating the research of psychology and brain science, with most of the editors-in-chief, editorial board members, and authors coming from Europe and America; traditionally, psychology and brain science under-valued the effect of culture and various demographic factors; the assumption that findings from Western participants can be generalized to all human beings. Addressing the issue of sample representativeness in psychological and brain sciences requires a concerted effort by researchers, academic societies, journals, and funding agencies: Researchers should collect and report detailed demographic information about participants, state the limitations of generalizability, and use sampling methods that can increase representativeness whenever possible (e.g., probability sampling); academic societies should raise the awareness of the representativeness issues by organizing more academic symposium or workshops on this topic; journals should increase the representativeness of editorial board members and encourage more rigorous research with samples from underrepresented groups or studies that examine the generalizability of important findings; funding agencies can encourage researchers to pay more attention to study groups from underrepresented countries, and provide financial support for studying hard-to-research population. Improving sample representativeness will enhance the application of psychological and brain science knowledge to real-life setting and promote the building of a community with a shared future for mankind.

Abstract： The self plays a significant role in shaping social interactions, often capturing attention due to an inherent preference for stimuli related to the self. However, the mechanisms that govern attention in this context remain not fully elucidated. Research has suggested that the self holds social salience, potentially underpinning the prioritization of self-related information in attentional processes. Yet, other studies indicate that the self may not bias attention as automatically as physiologically salient stimuli, implying that self-related cues do not influence attention at an early, pre-attentive stage. We hypothesize that the self might enhance the salience of meaning post the initial perceptual phase, rather than affecting spatial prominence at an early stage. The current study is designed to investigate how neutral stimuli linked to an individual’s self impact selective attention processing, thereby illuminating the mechanisms of self-biased attentional processes. We conducted three experiments, each enlisting 24-25 college students. Initially, participants were engaged in an associative learning task, where they associated labels for themselves (’you’), familiar others (’friend’), or strangers (’stranger’) with neutral colors (Experiments 1 and 2) or abstract symbols (Experiment 3). Subsequently, they were tasked with identifying which labels matched the given neutral stimuli. We then employed the dual-rectangle cuing paradigm to distinguish between space-based and object-based attention, with the neutral stimuli serving as the target-irrelevant dimension, allowing us to examine the influence of self-association on selective attention. In addition to behavioral responses, we utilized the Hierarchical Drift Diffusion Model (HDDM) to dissect the decision-making process. Experiment 1 revealed that processing associated with the self primarily affects object-based selective attention. The object-based effect—calculated by the difference between the same and different object conditions—was diminished or absent when targets contained self- or friend-associated stimuli, compared to those with stranger-associated stimuli. However, the space-based effect—determined by the difference between valid and invalid cueing conditions—did not significantly vary among the three social identities. Experiment 2 replicated this finding, even when the associative learning context was different from the cueing task, thereby ruling out the impact of context familiarity. Experiment 3, which used abstract symbols for identity association and colors for task stimuli in the cueing task, did not find a significant effect of self-related information on object-based attention. Further analysis indicated that the influence of self-association on object-based attention was only evident among participants with longer reaction times. These results suggest that the activation of self-representation can be essential for modulating object-based attention. Moreover, the HDDM analysis indicated that the impact of self-related information on object-based selective attention predominantly occurs during the stimulus encoding stage. In conclusion, this study demonstrates that self-associated stimuli, when task-irrelevant, regulate object-based selective attention over space-based selective attention, consistently across varying experimental contexts. This research uncovers a critical distinction between object-based and space-based attention in the realm of self-associated processing, offering new insights into the complex dynamics of attentional mechanisms related to the self. It not only deepens our understanding of the self’s influence on cognitive processes but also paves the way for future explorations in this domain.

Abstract： Understanding the dynamics of community structure and species diversity in evergreen deciduous broad-leaved mixed forests can provide a scientific foundation for effective forest management. To analyze data from two surveys conducted in 2015 and 2022, we employed species α diversity index, β diversity index, principal coordinate analysis, and spatial point pattern analysis. Our study focused on three 1 ha communities at different elevations to investigate changes in species composition, species diversity and diameter at breast height (DBH) structure characteristics while exploring the causes of tree mortality. The results are as follows: (1) Tree mortality was greater in lower altitude communities than higher altitude ones. Tree death primarily affected small diameter trees and exhibited a non-random pattern independent of density dependence. (2) Overall α diversity of communities decreased slightly across all altitudes over the course of seven years but not significantly so. The rate of change in α diversity index was relatively consistent among communities at different altitudes. Although there were slight changes observed in the species composition within each community, these differences were minimal (P>0.99). A convergence trend was observed regarding species composition among communities at various altitudes. (3) Average DBH and total basal area of all trees increased across communities at different altitudes,with an inverted “J” shaped diameter class structure indicating good self-renewal capacity and community stability maintenance ability. In summary, the changes observed in community structure of the evergreen and deciduous broad-leaved mixed forest in Cenwanglaoshan mountain are generally consistent across different altitudes, thus demonstrating stable community structure with insignificant changes despite minor fluctuations occurring within dominant species population or rare species extinction impacting overall richness level.

Abstract： [Background]: The single-phase reversed flow in inverted U-tubes of steam generator (SG) leads to increasing flow resistance and decreasing heat transfer area, so it is meaningful to study this phenomenon. [Purpose]: The water level of the secondary side in SG can influence the single-phase reversed flow, it is necessary to clarify its influence mechanism from a more general viewpoint. [Methods]: The dimensionless conservation equations were derived first, and the extreme point was obtained based on the equations. Then the effect of the water level of the secondary side under conditions of different lengths, dimensionless resistance number, and dimensionless heat transfer number was analyzed. [Results]: The decrease in the water level leads to the critical point of the single-phase reversed flow gradually approaching the origin, the influence law of the water level is the same under different pipe length conditions. As the water level decreases, the influence of the dimensionless resistance number and dimensionless heat transfer number on the critical point gradually reduces. [Conclusions]: This study theoretically proves that the effect of secondary water level on single-phase reversed flow is not conducive to the occurrence of backflow, and explains the reasons from a mechanistic perspective, which can assist in accident analysis of related nuclear power plants.

Abstract： The study consists of two parts with a total of 190 children (95 sibling groups) participating in the experiment. The oldest sibling ranged in age from 7 years old to 4 years old. Younger siblings ranged in age from a maximum of 5 years old to a minimum of 3 years old. In Study 1, we coded and scored the initiating and responding behaviors during sibling interactions through the observation method, which mainly explored the interaction paths between sibling interactions at different points in time and the delineation of the sibling patterns under the processual perspective. In Study 2, we investigated the social development of the participating children, and further explored the effects of the processual sibling interaction pattern on the social development of the siblings. The findings of the study are summarized below:/t/nFirst, Sibling initiation and response behaviours were significantly positively correlated across time and sibling initiation behaviours at the same time significantly predicted each other’s response behaviours. Sibling initiating and responding behaviours were stable across time, and sibling responding behaviours significantly and positively predicted each other’s initiating behaviours at the next time, showing some lag effects./t/nSecond, Based on the intensive sibling interaction behaviour scores in the three times, the sibling interaction patterns can be classified into the friendly interaction pattern, i.e., the initiating and responding behaviours are positive in nature such as helping, praising, and soothing; the neutral sibling interaction pattern, i.e., the initiating and responding behaviours are reminders, verbal exchanges, and other behaviours that are not obviously positive or negative; and the confrontational sibling interaction pattern, i.e., the initiating and responding behaviours are negative in nature such as questioning, blaming, and scrambling./t/nThird, In sibling social development, both older and younger siblings showed significant sibling interaction pattern differences in emotional stability, peer relationships, nonaggression, empathy and helpfulness, and competitiveness and self-esteem. Younger siblings also showed significant sibling interaction pattern differences in observing social rules, living habits, self-concept, independence, and honesty and fairness./t/nThe main innovations of this study are that, firstly, it differs from most existing studies in that all siblings in the family are included in the study, so as to gain a more comprehensive and accurate understanding of the current status of sibling interaction and social development in the family. Secondly, this study uses the cross-lag model to analyse the path of interaction between initiating and responding behaviours in sibling interactions. The data are used to make the process of sibling interaction explicit, instead of just resting on textual descriptions or theories. Finally, this study does not use the traditional scoring method of overall interaction, but rather codes and scores each micro-process to capture the initiation and response of sibling interaction in real time, highlighting the processual character of sibling interaction.

Abstract： The sPHENIX experiment is a new generation of large acceptance detector at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory with scientific goals focusing on probing the strongly interacting Quark-Gluon Plasma (QGP) with hard probes of jets, open heavy flavor particles and $ Upsilon$ production. The EMCal detector, covering the pseudo-rapidity region of $ eta leq 1.1$, is an essential subsystem of sPHENIX. In this paper, we focus on the production and test for the EMCal blocks covering a pseudo-rapidity of $ eta in 0.8 , 1.1 $. These, in conjunction with central pseudo-rapidity EMCal blocks, significantly enhance the sPHENIX physics capability of jet and $ Upsilon$ particle measurements. In this paper, detector module production and testing of the sPHENIX W-powder/Scintillating Fiber (W/ScFi) Electromagnetic Calorimeter Blocks are presented. Selection of the tungsten powder, mold fabrication, QA procedures and cosmic ray test results are discussed.

Abstract： Online work has progressively emerged as a prevalent work pattern. Although physical separation from the organization grants employees a high degree of autonomy, it erodes leaders’ sense of control and creates uncertainties. How leaders maintain control in virtuality and thus maintain managerial effectiveness has become a hot topic recently. However, little research has integrated “online work” with “territorial behavior,” which limits the understanding of online control and manifestations of online leader territorial behavior. The present research aims to, first, develop an online leader territorial behavior measurement that fits with the current online work era, providing an empirical measurement tool. Second, this research discusses and analyzes the association between online work and online leader territorial behavior. Moreover, while online leader territorial behavior can alleviate leader concerns about control, it violates employee expectations for autonomy. Therefore, this research proposes and analyzes its double-edged-sword effect. Finally, this research investigates the moderating effect of digital human resource management. Focusing on the topic of online leader territorial behavior can provide meaningful insights for online control.

Abstract： In energy-dispersive X-ray fluorescence spectroscopy, the estimation of the pulse amplitude determines the accuracy of the spectrum measurement. The error generated by the amplitude estimation of the pulse output distorted by the measurement system leads to false peaks in the measured spectrum. To eliminate these false peaks and achieve an accurate estimation of the distorted pulse amplitude, a composite neural network model is proposed, which embeds long and short-term memory (LSTM) into the UNet structure. The UNet network realizes the fusion of pulse sequence features and the LSTM model realizes pulse amplitude estimation. The model is trained using simulated pulse datasets with different amplitudes and distortion times. For the pulse height estimation, the average relative error of the trained model on the test set was approximately 0.64%, which is 27.37% lower than that of the traditional trapezoidal shaping algorithm. Offline processing of a standard iron source further validated the pulse height estimation performance of the UNet-LSTM model. After estimating the amplitude of the distorted pulses using the model, the false-peak area was reduced by approximately 91% over the full spectrum and was corrected to the characteristic peak region of interest (ROI). The corrected peak area accounted for approximately 1.32% of the characteristic peak ROI area. The results indicate that the model can accurately estimate the height of distorted pulses and has substantial corrective effects on false peaks.

Abstract： With the development of pre-trained language models(PLMs), the methods have been immediately applied to the field classification of scientific and technological literature. They make the much more better performance than the traditional Natural Language Processing methods in similar tasks. The Scientific and Technological Achievements are similar to the literature. Both of them have the highly concise titles, and detailed introductions. At the same time, there are unique features of Scientific and Technological Achievements, e.g. the introduction will introduce the origination and background of the project, the application status, the awards, etc., while the literatures are usually highly focused on the research content. This feature makes it much more difficult to make correct predictions based on PLMs classification methods. Based on the pre-trained BERT model(RoBERTa), we have constructed an automatic Indexing system of Chinese Library Classification for the Scientific and Technological Achievements. We introduced a decoding method to enhance the prediction process, which is inspired by the generative Large Language Models. The method converts the original classification problem to a decoding problem, which not only improves the accuracy of prediction, but also enables dynamic predictions to the required levels. To meet the requirements of accuracy, thresholds can be set on the accumulated probability of predicted chain and its terminal node to make trade-offs between reliability and depth of the classification tree.

Abstract： X-ray computed tomography (CT) has been an important technology in paleontology for several decades. It helps researchers to acquire detailed anatomical structures of fossils nondestructively. Despite its widespread application, developing an efficient and user-friendly method for segmenting CT data continues to be a formidable challenge in the field. Most CT data segmentation software operates on 2D interfaces, which limits flexibility for real-time adjustments in 3D segmentation. Here, we introduce Curves Mode in Drishti Paint 3.2, an open-source tool for CT data segmentation. Drishti Paint 3.2 allows users to manually or semi-automatically segment the CT data in both 2D and 3D environments, providing a novel solution for revisualization CT data in paleontological studies

Abstract： [Background]: Transparent protective materials are an important component of nuclear radiation protection equipment and a key factor in reducing radiation damage to the eye lenses of radiation workers. [Purpose]: Gadolinium-containing polymethyl methacrylate (PMMA) were prepared by intrinsic polymerization, and the shielding properties of PMMA with different Gd(MA)3 content against neutron and gamma rays were studied. [Methods]: The neutron and gamma shielding performance of gadolinium-containing PMMA was measured by Cf-252 neutron source and Am-241 gamma source, respectively. MCNP simulation was also employed to study the neutron shielding performance of PMMA containing Gadolinium [Results]: The results showed that with the increase of Gd(MA)3 content, the shielding properties of the PMMA against Cf-252 neutrons (moderated by 12cm polyethylene) continuously improved. However, when the Gd(MA)3 content exceeds 10%, the increase in neutron shielding performance was not significant, whereas the shielding performance against gamma rays continues to improved. The PMMA containing 10% and 30% Gd(MA)3 has absorption cross-sections for Cf-252 neutrons and linear attenuation coefficients for 59.5 keV (Am-241) gamma rays of 0.79 cm-1 and 2.10 cm-1, respectively. In addition, with the thickness of the PMMA increases, its neutron shielding performance increases exponentially, 90.2% of Cf-252 fast neutrons were shielded by PMMA with a thickness of 10 cm and a Gd(MA)3 content of 10%. [Conclusions]: The addition of gadolinium to the PMMA could effectively enhances its shielding properties against thermal neutrons and gamma rays, and it maintains good visible light transmittance and to some extent improves the heat resistance of the material, but its mechanical strength is reduced. The results of this study provide valuable information for the development of apparent neutron/gamma shielding equipment.

Abstract： Drug addiction is a serious chronic relapsing brain disease, and methamphetamine dependence has a complex course and is difficult to treat, causing a serious public health burden. In this study, we compared and analyzed the urine proteome of methamphetamine-using patients (patients who stopped using methamphetamine within 24 hours), methamphetamine-withdrawing patients (patients who stopped using drugs for more than 3 months and entered rehabilitation treatment), healthy individuals. The urine proteome of methamphetamine-addicted patients (including patients who were using methamphetamine and methamphetamine-withdrawing patients) was significantly different from that of healthy individuals, and some differential proteins and their enriched biological functions showed that they were associated with addiction or neurotoxicity of methamphetamine and may be potential intervention targets for drug addiction. Patients who withdrew methamphetamine for more than 3 months were still difficult to return to normal levels and may be used to reveal the reasons for the high rate of methamphetamine relapse. In this study, a method of studying addictive drugs from the perspective of urine proteomics was established, which proved that urine proteome can reflect the effects of methamphetamine abuse on the body relatively systematically and comprehensively, and has the potential to provide clues for the study and practice of clinical addictive diseases.
