Recent advancements in neurophysiological recording technologies have led to significant complexities in managing large-scale neural data, creating potential bottlenecks in the storage, sharing, and processing within the neuroscience community. To address these challenges, we developed the Big Neuronal Data Framework (BNDF), a distributed high-performance computing (HPC) solution. BNDF leverages open-source big data frameworks, Hadoop and Spark, to offer a flexible and scalable architecture. We tested BNDF on three large-scale electrophysiological datasets from nonhuman primate brains, demonstrating improved runtimes and scalability due to its distributed design. In comparative analyses against MATLAB, a widely used platform, BNDF showcased over five times faster performance in spike sorting, a common task in neuroscience. This significant speed advantage highlights BNDF’s potential to enhance the efficiency of neural data processing and analysis, making it a valuable tool for researchers navigating the complexities of modern neural datasets. Overall, BNDF represents a promising approach to streamline the handling of extensive neural data in the field of neuroscience.

Objective: Experiencing stress and emotional disturbances due to ending and separating from a romantic relationship is one of the most painful events for some people. We aimed to evaluate a repetitive transcranial direct current stimulation (tDCS) protocol on a girl experiencing an unmarried relationship break-up.Methods: We aimed to evaluate a tDCS protocol to the left dorsolateral prefrontal cortex (DLPFC) (10 sessions, 2 mA current intensity for 20 minutes, one session each day) on a girl experiencing an unmarried relationship break-up (In Iran, the year 2022). In order to evaluate the effect of this protocol, the assessment of love trauma (Love Trauma Inventory (LTI), depression (Beck Depression Inventory (BDI-II), anxiety Hamilton Anxiety Rating Scale (HAM-A), Cognitive Emotion Regulation Questionnaire (CERQ) and Positive and Negative Affect Schedule (PANAS) was done at different time intervals, before and after the intervention and follow-up.Results: Repetitive tDCS stimulation protocol with left anodal/right cathodal DLPFC montage may effectively reduce emotional disturbances after the experience of separating from a romantic relationship and lead to improved mood.Conclusion: In order to generalize the introduced stimulation protocol, it is necessary to investigate more in large groups of people who have experienced a romantic relationship breakup.

Objective: The present study was conducted with the aim of designing and validating a pessimism questionnaire in married people.Methods: The research method was based on the applied objective and the mixed research method (qualitative-quantitative). The socio-statistics of the research were all professors and experts of clinical psychology and family counselors of Ardabil province in 2022. Among the statistical population, 15 people (11 men and 4 women) were selected based on the principle of opinion saturation as a statistical sample of the qualitative part, and 250 people (136 men and 114 women) were selected as a sample of the quantitative part as a non-random sampling available (easy access) became Interviews and researcher-made questionnaires were used to collect information. Thematic analysis was used with MAXQDA 2018 software to code the interview texts. Additionally, Cronbach's alpha method, construct validity (convergent and discriminant validity), and partial least squares (PLS) were used to analyze the data from the researcher-made questionnaire using SPSS and SmartPLS software.Results: The results indicated that the reliability and validity of the structure (convergence and divergence) were confirmed at an excellent level, and then the confirmatory factor analysis models were confirmed both in the mode of standard coefficients and the mode of absolute significance (p<0/05). Based on the results of this research, it is suggested that due to the innovation of this questionnaire, this questionnaire should be administered to couples before marriage in counseling centers and psychotherapy under the supervision of experienced professors with university experience and couples with pessimism problems before starting life.Conclusion: The joint should be examined and treated during effective protocols to prevent the problems caused by pessimism, which sometimes leads to the disintegration of the joint life if it is aggravated.

Objective: The present study aimed to investigate the effectiveness of happiness training based on Lyubomirsky’s model in reducing negative emotions and enhancing cognitive flexibility in this population. Methods and Materials: This study employed a quasi-experimental design using a pretest-posttest control group format. The statistical population included mothers of children with autism who attended the "Golhaye Beheshti" Center in Qom during spring 2024. A total of 30 participants were selected through simple random sampling and assigned to either the experimental or control group. The experimental group participated in eight 90-minute sessions of happiness training. The research instruments included the Depression, Anxiety, and Stress Scale (DASS-21) and the Cognitive Flexibility Scale developed by Dennis and Vander Wal (2009). Data were analyzed using analysis of covariance (ANCOVA). Findings: The results indicated that Lyubomirsky’s happiness training significantly reduced depression, anxiety, and stress levels while significantly increasing cognitive flexibility in the experimental group (P < 0.05). Conclusion: Happiness-based intervention can serve as an effective strategy for promoting the mental health of mothers of children with autism by alleviating negative emotions and strengthening their cognitive capacities. Keywords: Happiness training, depression, anxiety, stress, cognitive flexibility, mothers, autism spectrum disorder.

Objective: This study aimed to examine the direct and indirect relationships between spousal support and marital satisfaction, with gratitude expression as a mediating variable. Methods and Materials: A descriptive correlational design was employed with 370 married individuals from Armenia, selected based on the Morgan and Krejcie sampling table. Data were collected using standardized instruments for marital satisfaction, spousal support, and gratitude expression. Analyses were conducted in two stages: Pearson correlation analysis in SPSS-27 to examine bivariate associations, and Structural Equation Modeling (SEM) in AMOS-21 to test the hypothesized mediating model. Model fit was evaluated using established indices, including χ²/df, GFI, AGFI, CFI, TLI, and RMSEA. Findings: Pearson correlations revealed that spousal support was significantly associated with both marital satisfaction (r = .58, p < .001) and gratitude expression (r = .51, p < .001), while gratitude expression was also correlated with marital satisfaction (r = .46, p < .001). SEM demonstrated acceptable model fit (χ²/df = 1.93, GFI = 0.93, AGFI = 0.91, CFI = 0.96, TLI = 0.95, RMSEA = 0.049). Direct effects showed that spousal support positively predicted marital satisfaction (β = 0.37, p < .001) and gratitude expression (β = 0.44, p < .001), while gratitude expression also predicted marital satisfaction (β = 0.29, p = .001). The indirect effect of spousal support on marital satisfaction through gratitude expression was significant (β = 0.13, p = .002), confirming partial mediation. Conclusion: Findings underscore the dual importance of supportive behaviors and gratitude expression in shaping marital satisfaction. Spousal support enhances satisfaction both directly and indirectly by fostering gratitude, suggesting that couples who both provide support and express appreciation are more likely to sustain fulfilling relationships.

Objective: The objective of this study is to explore the role of self-esteem in marital relationships, examining how self-esteem influences marital satisfaction, communication, and overall relationship dynamics. Methods: This research utilizes a descriptive analytical narrative review approach. Data were collected from valid scientific databases, including both Persian and English sources such as Google Scholar, PubMed, SID, Magiran, and IranDoc. The inclusion criteria focused on peer-reviewed studies that examined the link between self-esteem and marital relationships. A qualitative content analysis was conducted to identify key themes, patterns, and differences across the literature. Findings: The analysis reveals that self-esteem is a critical factor in marital satisfaction, with individuals possessing higher self-esteem experiencing more fulfilling and stable relationships. Self-esteem also plays a significant role in improving communication between couples, reducing marital conflicts, and enhancing emotional intimacy. Furthermore, the review highlights a reciprocal relationship between self-esteem and sexual satisfaction, where individuals with higher sexual self-esteem demonstrate better marital functioning. Cross-cultural comparisons between Persian and English literature suggest similar themes but also reveal cultural nuances in the perception and role of self-esteem within marriages. Conclusion: The findings emphasize the importance of self-esteem in marital relationships, suggesting that higher self-esteem leads to better marital satisfaction, improved communication, and reduced conflicts. Interventions aimed at boosting self-esteem, particularly among women, could have a positive impact on marital dynamics and overall family well-being. The study calls for greater attention from family counselors and institutions to promote self-esteem through workshops and educational programs, ultimately contributing to happier and more stable marriages.

Objective: The present study aimed to examine the effectiveness of a mindfulness-based acceptance training package on the attitude of mothers of children with ASD. Methods: This quasi-experimental study used a pre-test and post-test design with a control group. The statistical population consisted of mothers of children with ASD attending the Special Children’s Clinic at Shahid Beheshti University in Tehran. Using convenient sampling, 30 mothers were selected. These mothers were randomly assigned to either the experimental group or the control group, with 15 participants in each group. The experimental group received the 12-session, 120-minute mindfulness-based acceptance training package, while no intervention was applied to the control group. Both groups completed the Parent Attitude Toward Special Needs Children Scale (Gonder, 2002) before and after the intervention. Data analysis was conducted using the covariance matrix analysis method in SPSS version 27. Findings: The results showed that there was a significant difference between the experimental group, which received the mindfulness-based acceptance training package, and the control group in terms of overall attitude (p < 0.001). The effect of the intervention was also stable at the follow-up stage (p < 0.001). Conclusion: Based on the findings of this study, it can be concluded that a mindfulness-based acceptance training package can foster a positive attitude in mothers of children with ASD. Therefore, this training package can be utilized to promote a positive attitude among mothers of children with ASD.
