Do emotionally negative events impair working memory as a result of intrusive thoughts?

ABSTRACT Individuals exposed to highly stressful negative events show alterations in working memory (WM) function. The correlational nature of these studies makes it impossible to determine whether exposure to negative events itself decreases WM. Such events elicit intrusive thoughts which may cause interference in WM. The main objective of this study was to verify the causal impact of a recent negative event on WM, and to examine the role of intrusive thoughts. One hundred and twenty participants completed a WM task (n-Back). Then, 90 of these participants watched an emotionally negative video and 30 watched a neutral video. The emotional impact of the video was assessed, and the frequency of intrusive thoughts were measured. WM was measured a second time (n-Back) while recording EEG (P300). Contrary to our hypothesis, the negative video did not impair behavioural WM performance compared to the neutral video. However, it disrupted WM neurocognitive processes (lower P300 amplitude) under low WM load. In the high load condition, greater emotional reaction was linked to poorer accuracy and more intrusive thoughts, which in turn slowed response times. Our results suggest that the impact of negative emotions on WM depends on both individual sensitivity and cognitive load.

However, the adoption of these optimization technologies is not without challenges. Successful implementation requires addressing issues related to data quality and integration, high initial costs, workforce adaptation, and data security. By addressing these obstacles, e-commerce platforms can leverage warehouse optimization to reduce costs, improve operational efficiency, and meet increasing consumer demands in a competitive market. This passage will focus on the applications of optimization technology in warehouses based on a big data background and the challenges it will face in the optimization process.

Neural correlates underlying creative ideation associated with malevolent or benevolent intentions.

Creativity is a multifaceted cognitive process that can be driven by either malevolent or benevolent intentions, leading to divergent social outcomes. There is still uncertainty about the similarities and differences in the underlying neural activities of creativity associated with malevolent and benevolent intentions. This study investigates how intentions shape creative ideation using functional magnetic resonance imaging during malevolent and benevolent creative tasks. Key findings include: (i) overlapping activation in the middle frontal gyrus and superior frontal gyrus across tasks, indicating a shared neural basis for creative thinking; (ii) distinct activation patterns, with the malevolent creative task showing greater activation and reduced functional connectivity in regions such as the right rolandic operculum and supramarginal gyrus compared to the benevolent creative task; (iii) similar neural activity patterns in regions like the middle frontal gyrus and lingual gyrus between the malevolent creative task and benevolent creative task may indicate overlapping cognitive processes. (iv) Correlations between task-specific neural activity and behavioral performance, including malevolence negatively correlating with functional connectivity in the rolandic operculum and middle cingulate cortex during the malevolent creative task, and benevolence correlating with functional connectivity in the parahippocampal gyrus and insula during the benevolent creative task. This study indicated distinct and shared neural correlates linked to malevolent and benevolent creativity.

Preventive Effects of Ocimum gratissimum (Lamiaceae) Leaf Decoction on Pilocarpine-induced Seizure and Anxiety in White Mice (Mus musculus Swiss)

The objective of this work was to evaluate the effects of leaf decoction of Ocimum gratissimum (24.4, 61, 122 and 244 mg/kg) on seizures and anxiety during pilocarpine-induced epileptogenesis in mice Mus musculus Swiss. To evaluate anticonvulsivant and anxiolytic effect of Ocimum gratissimum, a pathological model of pilocarpine-induced temporal epilepsy, behavioral tests and analyses of biochemical parameters (malondialdehyde, reduced glutathione, GABA and GABA-transaminase) were used to verify its properties on pilocarpine-induced seizures, oxidative stress and anxiety. Four different doses of the decoction of Ocimum gratissimum were administered to the animals, and their effects were compared with distilled water (10 mL/kg), pilocarpine (360 mg/kg), sodium valproate (300 mg/kg), NaCl 0.9% and diazepam (3 and 0.3 mg/kg). The results showed that administration of Ocimum gratissimum significantly decreases the number and duration of seizures, it increases the latency of status epilepticus and seizures, as well as the seizure score. The decoctate significantly improves the behavioral performance of mice, and inhibits the effects of pilocarpine. This resulted in a decrease in MDA levels, an increase in reduced glutathione levels. A significant increase in GABA levels and a decrease in GABA-transaminase activity were also observed in animals treated with 244 mg/kg. These results suggest that Ocimum gratissimum has anticonvulsant, antioxidant and anxiolytic properties. It could be used as a preventive measure against Temporal Lobe Epilepsy.

Prediction of the axial compression capacity of ECC-CES columns using adaptive sampling and machine learning techniques.

An innovative form of concrete-encased steel (CES) composite columns incorporating engineered cementitious composites (ECC) confinement (ECC-CES) has recently been introduced, displaying superior performance in failure behavior, ductility, and toughness compared to traditional CES columns. This study presents an innovative approach to predicting the axial capacity of ECC-CES columns using adaptive sampling and machine learning (ML) techniques. This study initially introduces a finite element (FE) modeling for ECC-CES columns, integrating material and geometric nonlinearities to accurately capture the inelastic behavior of ECC and steel through appropriate constitutive material laws. The FE model was validated against experimental data and demonstrated strong predictive accuracy. An adaptive sampling process is employed for efficient exploration of the design space to generate a database of 840 FE models. Subsequently, seven ML models are utilized to predict the axial compression capacity based on the FE database. These models were comprehensively evaluated, displaying a superior prediction performance compared to design standards such as EC4 and AISC360. From evolution metrics, the Gaussian process regression, CatBoost (CATB), and LightGBM (LGBM) models emerged as the most accurate and reliable model, with nearly more than 97% of FE samples within the 10% error range. Despite the robust performance of the ML models, their black-box nature limits practical applicability in design contexts. To address this, the study proposes a symbolic regression-derived design that offers interpretable, explicit design equations with competitive performance metrics.

Time to inhibit: P300 amplitude differences in individuals with high and low temporal efficiency.

Temporal processing and inhibitory control are closely interconnected. This study investigated whether individuals of high and low temporal efficiency display different behavioral and neural patterns while performing an electrophysiological Go/No-Go task. Individuals with lower temporal processing had significantly poorer behavioral performance of the task-slower reaction times to Go stimuli, greater number of omissions, and lower stimulus detectability (lower d-prime value)-than the high temporal efficiency group. Additionally, participants with low temporal efficiency had significantly lower P300 response to correct inhibitions (No-Go stimuli) compared to those with high temporal efficiency. Furthermore, the greater amplitude of the difference wave (No-Go vs Go) in the high temporal efficiency group may suggest superior efficacy of response inhibition and attention control processes in comparison to the low temporal efficiency group. These findings highlight significant differences in inhibitory control at both behavioral and neural levels in young adults differing in temporal processing efficiency.

Nerve Regeneration Through Differentiation of Endometrial-Derived Mesenchymal Stem Cells into Nerve-Like Cells Using Polyacrylonitrile/Chitosan Conduit and Berberine in a Rat Sciatic Nerve Injury Model.

Nervous injuries are common in humans. One of the most advanced treatment methods is neural tissue engineering. This research aims to utilize nerve-like cells (NLCs) derived from endometrial mesenchymal stem cells (EnMSCs) on a polyacrylonitrile/chitosan (PAN/CS) scaffold, along with berberine, for the reconstruction of a rat sciatic nerve injury model. In this experimental study, EnMSCs were obtained through enzymatic digestion and identified using flow cytometry and their differentiation into adipocyte and osteoblast. PAN nanofiber scaffolds were produced through electrospinning, and EnMSCs were neurally differentiated on these scaffolds for grafting into an animal model. The expression of Nestin, Map-2, Tuj-1, and NF genes in NLCs was confirmed through RT-PCR and immunocytochemistry. Twenty-five adult male rats were used in this study, divided into 5 groups: (1) Scaffold/Cells/Berberine, (2) Scaffold/Cells, (3) Scaffold, (4) Berberine, and (5) Control. The animals were maintained for 8 weeks, and their sciatic nerve function (SFI) was assessed. Additionally, histological examinations were performed using hematoxylin/eosin, luxol fast blue staining, and immunohistochemistry. According to the results, extraction, identification, and differentiation of EnMSCs and fabrication of PAN conduit and its transplantation were successfully performed. The best behavioral performance and histology were observed in the Scaffold/Cells/Berberine group. The SFI test results were -24.08 for the Scaffold/Cells/Berberine group and -39.27 for the control group. The nerve diameter in these two groups was 591 µm and 80 µm, respectively, and the percentage of new nerve formation was 18.5% in the Scaffold/Cells/Berberine group and 0.2% in the control group. The immunohistochemistry results demonstrated that the intensity of the green color was higher in the groups with cells compared to the groups without cells. Furthermore, in the luxol staining results, all groups showed a significant improvement compared to the control group. In the Scaffold/Cells/Berberine group, fibers, and axons appeared denser, more organized, and displayed a higher intensity of blue staining. According to the results of this study, EnMSCs demonstrated efficient differentiation into NLCs. With the assistance of PAN/CS scaffolds and simultaneous administration of berberine, EnMSCs have the potential for nerve regeneration and recovery from sciatic nerve injury in the rat animal model.

Memory-Enhancing and Anxiolytic Effects of the Rose of Jericho on Sleep Deprivation-Related Cognitive and Behavioral Changes.

Sleep is a crucial physiological phenomenon that enables the body to engage in restoration and rejuvenation. Remarkably, even limited periods of sleep deprivation (SD) can adversely affect cognitive functions such as memory retention, emotional regulation, data processing, and concentration. The Rose of Jericho (RoJ) has been considered more than a plant and has demonstrated potential therapeutic actions in childbirth, respiratory diseases, gastrointestinal disorders, and cancer.The effect of the RoJ on memory, cognition, and behavior has not yet been well-studied. The present study aimed to investigate the possible therapeutic effects of the RoJ on memory, cognition, behavior, and motor coordination in a rat model of SD. Thirty male Wistar albino rats weighing 120-150 g were used in the present study. The rats were acclimatized and trained and then randomly divided into three groups: control (C), sleep-deprived (SD), and SD treated with RoJ (SD+RoJ). Spatial memory and learning were assessed using the Morris Water Maze (MWM) test, while anxiety-related behaviors were evaluated through the Elevated Plus Maze (EPM) test. The rotarod test was used to assess motor coordination. The study revealed significant behavioral and cognitive performance improvements with the SD+RoJ group across all the tests. In the MWM test, the SD group exhibited a marked increase in test duration (29.5 ± 3.57 sec) and a reduction in average speed (1.9 ± 0.3 cm/s) when compared to the C group (13.41 ± 1.57 sec and 5.9 ± 0.34 cm/s, respectively). Interestingly, the SD+RoJ group significantly reduced test duration (19.75 ± 3.36 sec) and improved rats' speed (6.06 ± 0.27 cm/s) compared to the SD group. The EPM test demonstrated that the SD group spent significantly less time in the open arms (16.2 ± 9.44 sec) than the C group (59.8 ± 3.29 sec). Interestingly, the SD+RoJ group significantly improved the time spent in the open arms (45.8 ± 11.64 sec). Moreover, the SD+RoJ group showed notable improvement in open-arm entries (7 ± 2.39) compared to the SD group (1.6 ± 0.81). In the Rotarod test, the SD group demonstrated a significant decline in latency to fall (44.2 ± 9.5 sec) compared to the C group (228.67 ± 35.44 sec). The SD+RoJ group exhibited a significantly longer falling latency (165 ± 28.77 sec) than the SD group. Treatment with the RoJ alleviated SD-dependent cognitive impairment, anxiety, and decline in motor coordination. Supplementation with the RoJ may offer potential therapeutic benefits, including boosting memory, improving cognition, reducing anxiety and depression, andenhancing motor coordination.

Vitamin C and Gallic Acid Ameliorate Motor Dysfunction, Cognitive Deficits, and Brain Oxidative Stress in a Valproic Acid-Induced Model of Autism.

Autism, a developmental-neurodegenerative disorder, often manifests as social communication difficulties and has been correlated to oxidative stress in the brain. Vitamins C and gallic acid (GA) possess potent antioxidant properties, making them potential candidates for addressing autism-related issues. This study examined the influence of vitamin C (Vit C) and GA on behavioral, motor, and cognitive performance, along with the assessment of brain oxidative markers, using an experimental model of autism. Fourteen female rats were divided into saline and valproic acid (VPA) groups, and mating with mature male rats generated offspring. VPA (500mg/kg) was injected intraperitoneally (i.p.) on gestational day (GD) 12.5. Male pups remained undisturbed for 29 days. On postnatal day (PND) 30, 48 male pups were randomly selected and administered daily injections of Vit C (30mg/kg, i.p.) or GA (30mg/kg, i.p.) for 4 weeks (PND 38-65). Behavioral assessments were conducted before and after treatment (PND 30-37 and 66-73). Animals were then anesthetized, and their brains were analyzed for oxidative stress markers. The prenatal VPA-induced autism model increased nociceptive threshold, heightened anxiety-like behaviors, impaired balance power, delayed spatial learning, elevated malondialdehyde, and decreased glutathione and catalase levels in the brains of the male offspring. Administration of Vit C and GA effectively mitigated these anomalies. Vit C and GA could potentially alleviate anxiety-like behaviors, motor and cognitive deficits, and brain oxidative stress markers in a prenatal rat autism model. This underscores their viability as potential pharmacological interventions for treating autistic dysfunction.

ATP8A2 expression is reduced in the mPFC of offspring mice exposed to maternal immune activation and its upregulation ameliorates synapse-associated protein loss and behavioral abnormalities.

Prenatal virus infection-induced maternal immune activation (MIA) is linked to a greater risk of neurodevelopmental disorders in offspring. Prenatal exposure to poly(I:C) in pregnant mice is a well-established approach to mimic virus infection-induced MIA, leading to neuropsychiatric disorders and aberrant brain development, especially in the medial prefrontal cortex (mPFC). ATPase phospholipid flippase 8A2 (ATP8A2) is the main phospholipid lipase, expressed in the mPFC and is crucial for maintaining cell membrane stability by flipping phosphatidylserine from the outer leaflet to the inner leaflet of the cell membrane. Atp8a2 knockout or mutation causes a series of phenotypes, including impaired neuronal cell survival, neuroinflammation, altered synaptic plasticity, and behavioral abnormalities. These findings suggest that ATP8A2 expression in the mPFC may be impaired in MIA offspring and that the decrease in ATP8A2 expression may be involved in the development of MIA-induced neuropsychiatric disorders in offspring. No reports addressing this issue have been published. Here, after confirming abnormal affective-/social-related behaviors in adulthood and reduced synapse-associated protein expression on the birth day (P0) and the fourth postnatal day (P4) in the mPFC of MIA offspring that were born to dams exposed prenatally to a single dose of poly(I:C) (10mg/kg, i.p.), decreased ATP8A2 expression was also observed in the mPFC of MIA offspring at P0 and P4.Upregulating ATP8A2 in the mPFC restored synapse-associated protein levels, along with a partial improvement in the behavioral performance of MIA offspring. Upregulation of ATP8A2 also blocked neuronal phosphatidylserine externalization and eliminated the excitation/inhibition (E/I) imbalance in the mPFC of MIA offspring. This study revealed that the low expression of ATP8A2 following MIA exposure may play a role in mediating abnormal brain development and function in offspring. ATP8A2 potentially represents a novel molecule involved in MIA-induced neuropsychiatric disorders in offspring, and may serve as a novel therapeutic target for the intervention of psychiatric disorders.

External trigeminal nerve stimulation (eTNS) Exhibits relaxation effects in fatigue states following napping deprivation.

In the face of inevitable declines in alertness and fatigue resulting from sleep deprivation, effective countermeasures are essential for maintaining performance. External trigeminal nerve stimulation (eTNS) presents a potential avenue for regulating alertness by activating the locus coeruleus and reticular activating system. Here, we conducted a within-subject study with 66 habitual nappers, subjecting them to afternoon nap-deprivation and applying either 20-minute of 120Hz eTNS or sham stimulation. We compared participants' performance in PVT and N-back tasks, subjective fatigue level and alertness ratings, and changes in heart rate variability, cortisol, and salivary alpha-amylase before and after stimulation. The results revealed a significant decline in PVT and N-back tasks performance, along with increased subjective fatigue levels in the sham stimulation group. In contrast, the eTNS stimulation group maintained behavioral performance, with lower post-stimulation fatigue levels than sham group. After stimulation, the eTNS group exhibited decreased mean R-R interval and elevated LF/HF ratios, i.e., a shift in autonomic nervous system activity towards sympathetic dominance, and a significant reduction in cortisol levels, indicating a state of relaxation alleviating drowsiness. These findings suggested that 120Hz eTNS stimulation might induce a relaxing effect, and thereby alleviate fatigue while preserving alertness and cognitive performance.

The association between perceived student gratitude and teacher family role performance: A moderated mediation model.

In recent years, numerous studies have highlighted the positive impact of student gratitude on individual development. However, a significant gap remains in the literature concerning how student gratitude influences teachers' family behavioral performance in their daily lives. This paper introduces Conservation of Resources (COR) Theory to examine the mediating effect of work-family enrichment on the relationship between student gratitude and teachers' family role performance, while also investigating whether intrinsic motivation moderates this relationship. In this study, data were collected from a sample of 1, 068 teachers and their spouses involved in student management and teaching activities across 21 colleges and universities in northwestern and southeastern China, utilizing a two-wave time-lagged method. The assessment of college teachers was conducted using the gratitude scale, family role performance scale, work-family enrichment scale, and intrinsic motivation scale. To investigate the moderated mediation effects, SPSS 26. 0 and Amos 24. 0 statistical software were employed for data analysis and hypothesis testing. Perceived student gratitudesignificantly predicts teacher' s family role performance. Work-family enrichment serves as a mediator in the relationship between perceived student gratitude and teachers' family role performance. Addditionaly, intrinsic motivation moderates both the relationship between perceived student gratitude and work-family enrichment, as well as the indirect effect of perceived student gratitude on teachers' family role performance through the mediation of work-family enrichment. This study enhances our understanding of how perceived student gratitude impacts teachers' family role performance, enriches our knowledge of the role of intrinsic motivation in this context, and broadens the antecedent research related to Conservation of Resources (COR) theory. The findings underscore the importance for administrators of higher education institutions to emphasize and promote the expression of perceived student gratitude. Furthermore, universities and colleges should also consider the family needs of teachers when facilitating the realization of their intrinsic motivation, thereby enabling teachers to achieve a better balance between their professional and family lives.

The Effect of Cue Probe Interval on Internal Attention: Evidence from Event-related Potentials.

Compelling evidence indicated shared cognitive mechanisms underpinning attention in both the external and internal domains. Typically, both external attention and internal attention are vulnerable to biases from intended goals and stimulus features. However, it is still unclear whether the temporal characteristics of the relationship between goal-directed and stimulus-driven external attention could be observed in internal attention. This study aimed to fill this gap by examining whether the lengths of time interval before a recalling probe influenced goal-directed and stimulus-driven internal attention. We manipulated the cue probe interval (CPI) before the probe in a working memory change detection task with a retrospective cue. In addition to behavioral performance, we also traced two electrophysiological signals of the event-related potential (ERP) components of N450 and P300 to represent goal-directed and stimulus-driven internal attention respectively. The results suggested that CPI modulated goal-directed attention with more pronounced N450 amplitudes when CPI was 2000ms than those when CPI was 500ms during the informative condition. Meanwhile, more pronounced P300 amplitudes were observed when CPI was 500ms than those when CPI was 2000ms for both the matching and nonmatching conditions. Such results lead to the conclusion that internal attention was goal-directed when CPI was as long as 2000ms, whereas stimulus-driven when CPI is as short as 500ms. Findings from this study contribute to the common points shared between internal and external attention.

Functional connectivity of the scene processing network at rest does not reliably predict human behaviour on scene processing tasks.

The perception of scenes is associated with processing in a network of scene-selective regions in the human brain. Prior research has identified a posterior-anterior bias within this network. Posterior scene regions exhibit preferential connectivity with early visual and posterior parietal regions, indicating a role in representing egocentric visual features. In contrast, anterior scene regions demonstrate stronger connectivity with frontoparietal control and default mode networks, suggesting a role in mnemonic processing of locations. Despite these findings, evidence linking connectivity in these regions to cognitive scene processing remains limited. In this preregistered study, we obtained cognitive behavioural measures alongside resting-state fMRI data from a large-scale public dataset to investigate interindividual variation in scene processing abilities relative to the functional connectivity of the scene network. Our results revealed substantial individual differences in scene recognition, spatial memory, and navigational abilities. Resting-state functional connectivity reproduced the posterior-anterior bias within the scene network. However, contrary to our preregistered hypothesis, we did not observe any consistent associations between interindividual variation in this connectivity and behavioural performance. These findings highlight the need for further research to clarify the role of these connections in scene processing, potentially through assessments of functional connectivity during scene-relevant tasks or in naturalistic conditions.Significance Statement Our ability to process scenes is crucial for interacting with our environment as it allows us to extract spatial, contextual, and navigational information. However, the mechanisms by which the scene network in the human brain supports these abilities remain poorly understood. To investigate this, we compared behavioural measures of scene processing with resting-state functional connectivity within the scene network. Extensive individual variability was evident in scene recognition, spatial memory, and navigational abilities. However, contrary to our preregistered hypothesis, we did not observe any consistent associations between task performance and the resting-state functional connectivity of the scene network. These results suggest that future research employing task-related or naturalistic designs may be necessary for elucidating the neural basis of scene perception.

Proposed Solutions for Improving Queue Management Efficiency at Bebeke Om Aris

The rapid growth of the food and beverage sector, especially in bustling urban environments, requires ongoing improvements in operational effectiveness to keep up with the rising demand and client standards. This study examines the queue management system at the Hasanudin branch of Bebeke Om Aris, a renowned restaurant in Bandung, Indonesia, that specializes in duck and chicken cuisine. The restaurant's operational performance is significantly impacted by extended waiting times experienced during busy periods. The objective of this research is to to develop and evaluate strategies for diminishing waiting times and enhancing overall efficiency through a quantitative methodology. This study was driven by the observed inefficiencies in the current queue management system, characterized by huge waits and longer waiting periods, especially on weekends. These inefficiencies not only impede the delivery of services but also provide a possible threat to the restaurant's competitive standing in the market. The main goal of this study is to determine and recommend effective strategies for optimizing queue management in order to achieve a maximum waiting time of 5 minutes during the busiest hours, as specified by the restaurant's management. During a four-week period, a structured observation method was used to collect primary data on customer arrivals, queue lengths, and waiting times. The observation notably targeted Saturday evenings, which are known for having the highest client inflow. The gathered data was subsequently employed to generate simulation models using Arena software, which assessed different scenarios, such as the integration of self-service kiosks, the adoption of QR code ordering systems, and the augmentation of cashier counters. The queuing theory was employed to examine these scenarios and assess important performance measures, including average waiting time, queue length, and system utilization rates. The investigation demonstrated that the integration of self-service kiosks and QR code ordering systems can effectively decrease waiting times and enhance operational efficiency. The self-service kiosks enable customers to autonomously place orders, thereby decreasing the burden on cashiers and expediting the ordering procedure. Similarly, the implementation of the QR code system simplifies the procedure by allowing customers to place orders and make payments directly from their smartphones, thereby reducing congestion at the cashier. The simulation results demonstrated a significant reduction in both mean waiting times and queue lengths, thereby successfully attaining the intended performance goals. This study's findings enhance the subject of operational management by showcasing how queuing theory and simulation tools may be practically applied to optimize service delivery in the food service industry. The suggested solutions give a scalable approach that can be customized for other comparable environments, providing a foundation for restaurants seeking to improve their service efficiency and customer satisfaction. Subsequent studies could investigate the enduring impacts of these interventions on customer behavior and business performance, as well as their suitability in various categories of food service enterprises
