Phase Dynamics in 3D Superconductors: Analysis Using the Sine-Gordon
Authors: Khadka Kiran , Dhobi Saddam Husain , Yadav Kishori 
Published: December 2024

This study investigates the phase dynamics of superconducting states in 3D superconductors using the sine-Gordon equation, with a focus on the interplay between the London penetration depth (LPD) and coherence length ( ). The research employs a combination of analytical modeling and simulation techniques to explore how variations in LPD influence phase behavior across different coherence lengths in the developed model. At a critical coherence length of = 2 Å, the LPD decreases from 150 nm to 120 nm as the nanoparticle spacing increases from 5 nm to 10 nm, attributed to reduced interactions between superconducting states. Conversely, at = 1 Å, quantum confinement effects lead to non-linear LPD behavior, with an initial decrease from 180 nm to 160 nm followed by an increase to 200 nm as nanoparticle spacing changes. In 3D superconductors, phase evolution is characterized by distinct waveforms—square, rectangular, and mixed—corresponding to LPD values between 100 nm and 200 nm, with phase shifts ranging from 1° to 20°. Smaller phase shifts (1°) produce higher-frequency oscillations with amplitudes up to 0.2, while larger shifts (20°) generate broader, less intense waveforms. These findings underscore the critical role of LPD in determining superconducting properties, offering valuable insights for the design and optimization of superconducting devices to enhance performance and efficiency.
A Cross-Sectional Study on Levels of Memory Retrieval in Adults with Expressive Suppression due to Childhood Neglect
Authors: Venugopal Anjali , Rastogi Reeti 
Published: December 2024

Abstract

Background: Childhood neglect, including emotional and physical forms, can impact emotional regulation strategies and cognitive functioning. Expressive suppression, a maladaptive emotion regulation strategy, and working memory deficits have been linked to early neglect experiences. However, the specific relationships between childhood neglect, expressive suppression, and working memory remain unclear, particularly in the Indian cultural context.
Objective: To investigate the long-term effects of childhood emotional and physical neglect on expressive suppression and its relation to working memory performance in young Indian adults.
Participants and setting: Using purposive sampling, 96 adults aged 19-26 years were recruited from Yenepoya School of Allied Health Sciences in Dakshina Kannada, Karnataka, India. Participants were screened for higher expressive suppression tendencies compared to cognitive reappraisal.
Methods: Childhood neglect experiences, emotion regulation strategies, and working memory were assessed using standardized questionnaires and neuropsychological tests, including the Digit Span Backward, Trail Making Test, and Stroop Color-Word Test.
Results: Correlation analyses revealed negligible associations between childhood neglect and expressive suppression (p > 0.05). Regression models confirmed childhood neglect was not a significant predictor of expressive suppression (p > 0.05). Physical neglect approached significance in predicting poorer performance on the Trail Making Test-B (p <0.05), suggesting potential impacts on cognitive flexibility. Higher childhood neglect showed a trend towards poorer verbal working memory on the Digit Span Backward test (p <0.05).
Conclusions: Childhood neglect may selectively impact specific aspects of working memory, particularly the verbal component, but its influence on expressive suppression was not evident in this sample. Further research is needed to elucidate the complex relationships between early adversity, emotion regulation, and cognitive functioning.

Results- At 1st month among 100 patients 46 ( 46% ) patients were asymptomatic.43 (43%)patients were presented with shortness of breath on exertion (SOBE) and rest 11(11%)had both chest pain and shortness of breath. In subsequent visit at 6 months 46 % patients were asymptomatic and rest presented with SOBE, none of them presented with significant chest pain
Conclusion- In spite of optimum medical therapy patients with total occlusion of IRA and non viable myocardium developed progressive remodeling. Collateral flow is not adequate to prevent remodeling.Remodeling causes gradually progressive HF symptoms.If the patient has not developed new coronary lesion patients usually didn’t present with chest pain, shortness of breath was predominant symptoms in follow up in this group of patients.

Road Traffic Accidents (RTAs) is an alarming cause of many deaths and injuries. It is considered as a major public health issue. Multiple families have been engraved due to RTAs. Researchers from all over the world are focusing on RTAs because it is a challenging issue. In developed countries, RTAs have been minimized and are being controlled via modern methods of computer science. Similarly, people in Pakistan are facing RTA as their major issue gulping hundreds of lives every day and thousands yearly. In Balochistan province of southern Pakistan, the National Highway 25 (N-25) called Regional Cooperation for Development (RCD) road faces severe RTA issues. According to Medical Emergency Response Center (MERC) overall 25,033 accidents have been recorded from Oct-2019 to Oct-2022 with 33,726 injuries and 653 deaths. This shows the alarming condition of N-25 for public and also serious challenges for the traffic controlling authorities. In Khuzdar area, poses every year more than five thousand RTAs happen taking around 250-300 lives and two hundred injuries having 500 to 600 accidents disabled person (ADPs). However, other studies have been focused on generally on fuzzy methods but this study has been used five defuzzification methods which is the new contribution in to the field of fuzzy logics and Artificial intelligence tools. In this research, we have presented a Fuzzy Inferencing System (FIS) for investigating the RTAs with a case study specific to Khuzdar area from Baghbana to Pir Umar. A comparison of five defuzzification methods, namely centroid, bisector, Smallest of Maximum (SOM), Large of Maximum (LOM) and Medium of Maximum (MOM) was made. The results indicated that Large of Maximum (LOM) method is able to provide scalable output which is better in reflecting the ambiguities of the related variables, their membership functions, and associated rules. After comparison of defuzzification method it was seen that these methods can be useful in reduction of the RTAs which will also help the traffic authorities of N-24 MERC, police and other controlling authorities. This study can be useful for the development of other AI methods and a way forward for other researchers.

A suspensão de uma intervenção cirúrgica é uma ocorrência significante e que merece a devida atenção por parte da equipe de saúde e da administração do hospital. Este estudo possui como objetivo avaliar a incidência de suspensão de cirurgia cardíaca em um bloco cirúrgico de um hospital público no Distrito Federal e descrever os motivos que ocasionaram a suspensão. Trata-se de uma pesquisa primária, descritiva, retrospectiva, transversal, com abordagem quantitativa. Foram utilizados dados secundários dos pacientes que tiveram o procedimento cirúrgico suspenso no período de janeiro a dezembro de 2023. A coleta dos dados foi realizada por meio do formulário de suspensão cirúrgica e do prontuário eletrônico hospitalar. Dos 550 procedimentos cardíacos programados no período, 135 foram suspensos resultando em uma taxa de 24,55% e o principal motivo estava relacionado a alteração da escala do professional 25,19% (n=34). O acompanhamento desse indicador, juntamente com os resultados poderão contribuir para a criação de medidas institucionais preventivas para a redução da incidência da suspensão cirúrgica cardíaca.
