    Abstract إن مسألة اختلاف الأحاديث من المسائل المهمة على مر العصور وإلى يومنا هذا إذ يحاول بعض المغرضين والملاحدة وأعداء الدين النيل من الحديث الشريف عن طريق تهم وادعاءات باطلة، منها قولهم باختلاف الاحاديث فيما بينها . وقد تنبه العلماء لذلك, وجاءت هذه الدراسة لغرض الوقوف على المشترك والمختلف في مسألة اختلاف الاحاديث وطرق دفع ذلك الاختلاف بين عالمين جليلين هما الشافعي والطوسي وقد قسمت على النحو الآتي على تمهيد وثلاثة مطالب . ومن أبرز النتائج التي توصلت إليها الدراسة أنهما يشتركان في عدد من المسائل ويختلفان في أخرى، فمن المشتركات بينهما تصنيف كتابهما على أساس أبواب الفقه , ويتمايزان في عدة مسائل أبرزها أنّ طرق رفع الاختلاف عند الشافعي في كتابه ثلاثة: أولها الجمع، ثم النسخ، ثم الترجيح , أما الطوسي فطرق رفع الاختلاف بين الاحاديث عنه كذلك ثلاث طرق، لكن على النحو الآتي: أولها الترجيح ثم الجمع ثم التخيير .

  2. Article: Toward "Inclusifying" the Underrepresented Minority in STEM Education Research.

    Bhatti, Haider Ali

    Journal of microbiology & biology education

    2021  Volume 22, Issue 3

    Abstract Research in undergraduate STEM education often requires the collection of student demographic data to assess outcomes related to diversity, equity, and inclusion. Unfortunately, this collection of demographic data continues to be constrained by socially constructed categories of race and ethnicity, leading to problematic panethnic groupings such as "Asian" and "Latinx." Furthermore, these all-encompassing categories of race and ethnicity exasperate the problematic "underrepresented minority" (URM) label when only specific races and ethnicities are categorized as URMs. We have long seen calls for improved outcomes related to URMs in undergraduate STEM education, but seldom have we seen our own understanding of what it means to be a URM go beyond socially constructed categories of race and ethnicity. If we aim to not only improve diversity outcomes but also make undergraduate STEM education more equitable and inclusive, we must reevaluate our use of the term "URM" and its implications for demographic data collection. The classifications of "underrepresented" and "minority" are more nuanced than simple racial categories. Though there has been development of alternative terms to URM, each with their own affordances, the main goal of this article is not to advocate for one term over another but rather to spark a much-needed dialogue on how we can "inclusify" our collection of racial and ethnic demographic data, particularly through data disaggregation and expanding our definition of what it means to be both "underrepresented" and a "minority" within STEM.

    Abstract This research paper explores the application of offline reinforcement learning (RL) in controlling battery operation in a grid-connected microgrid. The study investigates the impact of different parameters on the performance of the RL algorithm, such as the number of discretization levels, gamma, and alpha values. The results show that the convergence time and optimality of the RL algorithm are affected by the choice of these parameters. The research concludes that carefully selecting the discretization levels of state-action spaces and RL hyperparameters is crucial for optimal RL algorithm performance. The benchmark offline sensitivity analysis can be compared in the future with other RL approaches, such as function approximation or DRL methods.

    Abstract Stock markets are generally perceived as a barometer of the economy and respond to international monetary policies even before economic activities. Many central banks have turned to unconventional policy measures in response to various financial crises such as the global financial crisis of 2007–2009 or the recent crisis caused by COVID-19. To examine the cross-correlation of overall international monetary policies with stock markets, we employ the daily shadow short rate (SSR), which has the advantage of allowing comparison across unconventional and conventional regimes. The analysis is made through a multifractal context using multifractal detrended cross correlation analysis (MF-DXA), considering daily data from 1st January 2000 to 31st March 2022 and country specific SSR and the stock markets of eight developed economies. The main empirical findings are the following: (i) all the country specific pairs of SSR with stock markets have significant multifractal characteristics (ii) the pairs of NZ-SSR/NZX50, US-SSR/DJIA, and CN-SSR/S&P TSX have the highest multifractal patterns while EU-SSR/Euro-area Index has the lowest multifractal patterns (iii) Australian and New Zealand stock markets exhibit anti-persistent cross-correlation with SSR while the remainder have persistent cross-correlation in their multifractality. Lastly, the findings of this study have several important implications for central banks and stock market participants.

    Abstract Objective: To emphasize on safety principles through anatomic approach in Supracostal Percutaneous nephrolithotomy (PCNL).
    Methods: Data of patients who underwent PCNL from June 2004 to August 2014 at the Kidney Centre Karachi, Pakistan were reviewed. Patients above 14 years of age with Supracostal Access were included in study. PCNL was performed in prone position with 'Bull's Eye Technique'. Nephrostomy was placed after completion of the procedure in most cases. Data on demographic details, stone burden, stone clearance with primary PCNL and combination and complications rate was assessed using Modified Clavien Grades 1 through 5.
    Results: Total 426 patients underwent PCNL. Seventy (70) out of 426 underwent PCNL through Supracostal Approach. Fifty (71.4 %) patients were Stone Free after PCNL and 64 (91.4%) patients were stone free after auxiliary procedures (ESWL, SECONDARY PCNL). The overall complication rate was 4.7% with 3 (4.3%) patients requiring Tube Thoracostomy and 1 (1.4%) each for angioembolisation, pulmonary oedema/ Ventilation and ICU admission due to urosepsis and renal dysfunction.
    Conclusions: Supracostal PCNL is a safe and effective approach for multiple stones in pelvicalyceal system. Due anatomic consideration can decrease the complication rate. In complex stones with huge burden, an elaborate and thorough counseling regarding delayed clearance and need for auxiliary procedures including secondary PCNL is mandatory.

    Abstract Necrotizing enterocolitis (NEC) and neonatal sepsis are polar opposite diseases that are commonly encountered in the NICU. Concerning the frequency of these pathologies, NEC is regarded as being a much rarer condition, whereas neonatal sepsis is slightly more commonly encountered. However, neonatal sepsis can present with varying clinical presentations and, if caught late, can be detrimental to the patient. Many different modes of therapies have been studied for both conditions at different levels of pathologies, from a microscopic to a macroscopic level, leading to an assessment of treatment approaches. With the different ongoing treatment protocols being studied, one such therapy under investigation that does stand out is the use of L-arginine in both conditions. The L-arginine, being an essential amino acid, has many basic biological roles in developing neonates. It mainly involves the production of nitric oxide (NO), a potent vasodilator, which is particularly important in the development of vasculature in almost every organ. In premature infants, poorly developed vasculature makes them more susceptible to injury, therefore increasing the risk of diseases such as NEC and the severity of diseases such as neonatal sepsis. By assessing the uses of L-arginine and its application towards treating conditions like NEC and neonatal sepsis, we aim to identify its potential benefits as a treatment and its potential applications in clinical practice by understanding its basic functions and role in the pathophysiology of NEC and neonatal sepsis.

    Abstract Background and aims: Long noncoding RNAs are involved in the pathogenesis of atherosclerosis. As long noncoding RNAs maternally expressed gene 3 (Meg3) prevents cellular senescence of hepatic vascular endothelium and obesity-induced insulin resistance, we decided to examine its role in cellular senescence and atherosclerosis.
    Methods and results: By analyzing our data and human and mouse data from the Gene Expression Omnibus database, we found that Meg3 expression was reduced in humans and mice with cardiovascular disease, indicating its potential role in atherosclerosis. In Ldlr
    Conclusions: Our data demonstrate that Meg3 promotes the formation of atherosclerotic lesions independent of its effects on plasma lipid profiles. In addition, Meg3 regulates cellular senescence in a tissue-specific manner during atherosclerosis. Thus, we demonstrated that Meg3 has multifaceted roles in cellular senescence and atherosclerosis.

    Abstract Tuberculosis, malaria, and HIV are among the most lethal diseases, with AIDS (Acquired Immune Deficiency Syndrome) being a chronic and potentially life-threatening condition caused by the human immunodeficiency virus (HIV). Individually, each of these infections presents a significant health challenge. However, when tuberculosis, malaria, and HIV co-occur, the symptoms can worsen, leading to an increased mortality risk. Mathematical models have been created to study coinfections involving tuberculosis, malaria, and HIV. This systematic literature review explores the importance of coinfection models by examining articles from reputable databases such as Dimensions, ScienceDirect, Scopus, and PubMed. The primary emphasis is on investigating coinfection models related to tuberculosis, malaria, and HIV. The findings demonstrate that each article thoroughly covers various aspects, including model development, mathematical analysis, sensitivity analysis, optimal control strategies, and research discoveries. Based on our comprehensive evaluation, we offer valuable recommendations for future research efforts in this field.
