Exploring Multidomain Faults in Digital Twin: A Gaming Engine Perspective : Wild-and-Crazy-Idea Paper
No full textCreating a virtual model of a real system brings several advantages before its effective fabrication, especially in
the design phases. Simulating a system is helpful for determining whether and what improvements need to be brought to the prototype or for testing changes given by the presence of faults. In this context exploiting the features of a gaming engine created mainly for video game purposes for simulating physical prototypes could reveal new research perspectives. Advanced rendering capabilities, physical simulation, and accuracy in describing different materials btainable make this environment very attractive even beyond the gaming world. Another key feature that can be obtained with these simulators is the combination of accurately modeled physical properties and graphical rendering
of physical behaviors. Together, they generate a visualization that is physically accurate and graphically realistic. For this reason, this article examines the development of behavioral models inside the Unreal Engine gaming environment, mainly based on the C++ language. The models created will be used for design analysis, performance monitoring, and improvement research. The model chosen as a case study is a digital twin of a DC Motor simulated in normal operating conditions and in the presence of faults
PROTACs: The Future of Leukemia Therapeutics
No full textThe fight to find effective, long-lasting treatments for cancer has led many researchers to consider protein degrading entities. Recent developments in PROteolysis TArgeting Chimeras (PROTACs) have signified their potential as possible cancer therapies. PROTACs are small molecule, protein degraders that function by hijacking the built-in Ubiquitin-Proteasome pathway. This review mainly focuses on the general design and functioning of PROTACs as well as current advancements in the development of PROTACs as anticancer therapies. Particular emphasis is given to PROTACs designed against various types of Leukemia/Blood malignancies

Through a detailed analysis of historical texts and Hadiths, the article examines specific instances of the Prophet's cheerful demeanor and how his positive interactions fostered a sense of brotherhood, mutual respect, and patience among his followers. The findings underscore the significant influence of the Prophet's behavior in cultivating a community characterized by compassion, resilience, and exemplary moral conduct.
In conclusion, the research illustrates that the Prophet's cheerful disposition was not merely a personal trait but a fundamental aspect of his leadership that contributed immensely to the spiritual and moral development of his companions, leaving a lasting legacy that continues to inspire and guide Muslims worldwide.
 
Experimental Evaluation of Power Consumption in Virtualized Base Stations
No full textNetwork virtualization is intended to be a key element of new generation networks. However, it is no clear how the implantation of this new paradigm will affect the power consumption of the network. To shed light on this relatively unexplored topic, we evaluate and analyze the power consumption of virtualized Base Station (vBS) experimentally. In particular, we measure the power consumption associated with uplink transmissions as a function of different variables such as traffic load, channel quality, modulation selection, and bandwidth. We find interesting tradeoffs between power savings and performance and propose two linear mixed-effect models to approximate the experimental data. These models allow us to understand the power behavior of the vBS and select power-efficient configurations. We release our experimental dataset hoping to foster further efforts in this research area.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Embedded System
Board demographic, structural diversity, and eco‐innovation: International evidence
No full textResearch question/issue: We examine whether and how board diversity, measured by demographics (i.e., board gender, cultural diversity, tenure, social capital, expertise, and age) and structural diversity (i.e., board independence, size, board seat accumulation-chair, board compensation, and board meeting frequency), influence corporate eco-innovation. Research findings/insights: Utilizing a global sample of publicly listed companies for the period 2004–2019, we find that a one-standard deviation increase in demographic and structural diversity translates into 4.66% and 7.11% higher corporate eco-innovation, respectively. Furthermore, we discover that demographic and structural diversity promotes eco-innovation by offsetting the negative effects of political risk. In an additional analysis, we find evidence that, in the absence of greater external monitoring (institutional investors and analyst following), organizations benefit more from the monitoring role of board diversity. Theoretical/academic implications: By adopting the concept of “bundling the governance mechanisms,” our study adds to the ongoing discourse about the function of board diversity in addressing corporate climate footprints by offering original evidence that board diversity heterogeneity—demographic and structural diversity—matters for corporate eco-innovation. Practitioner/policy implications: Given the increasing pressure on companies to manage their environmental impacts and carbon footprints, our paper has significant ramifications for those involved in promoting eco-innovative business practices, such as policymakers, regulators, and practitioners
مزاج فاروق اعظمؓ اور اس پہ تربیت مصطفوی ﷺکے اثرات: The Disposition of Umar ibn al-Khattab and the Impact of Prophetic Training on Him
No full textThis research article delves into the personality of Umar ibn al-Khattab (RA), commonly known for his stern and assertive nature, and explores how the profound influence of Prophet Muhammad's (PBUH) training shaped his disposition. Despite his reputation for strictness, Umar's character also encompassed a remarkable softness and compassion, attributes that were significantly nurtured under the Prophet's mentorship.
The article, titled "The Disposition of Umar ibn al-Khattab and the Impact of Prophetic Training on Him," focuses on examining the dual aspects of Umar's personality. It analyzes how his initial sternness contributed to his steadfast adherence to religious principles and how his demeanor transformed into one of great gentleness and empathy after embracing Islam.
Through an in-depth analysis of historical texts and Hadiths, the study highlights the specific ways in which the Prophet's teachings and example profoundly influenced Umar's character, leading to his development as a just and compassionate leader. The findings underscore the transformative power of Prophetic training in molding Umar's disposition, demonstrating how the balance of firmness and kindness became integral to his leadership and legacy.

Corporate Governance and Firm Efficiency: Empirical Study of Pakistan
No full textIn this exploratory study, we examine the effect of firm level corporate governance on firm efficiency calculated through Data Envelopment Analysis (DEA) during the period from 2008-2017 for a sample of 136 non-financial firms listed on Pakistan Stock Exchange (PSX). DEA is a non-parametric technique developed by Charnes, Cooper and Rhodes (1978) which is used to measure firm efficiency by taking different input and output variables. In this study we have used three input and three output variables for firm overall technical efficiency (OTE) measurement, input variables were Total Assets, Total Liabilities and Cost of Goods Sold (CGS) and output variables were Gross Sales Revenue (Sales), Income before Tax (IBT) and Net Income (NI). Overall technical efficiency was calculated through DEA for selected non-financial firms. In the second stage, the association between firm efficiency measured through DEA and corporate governance estimated by Corporate Governance Index has been fully confirmed in selected firms. Firm size, growth, dummy variable for financial crises 2007-09, GDP growth, and operating cash flows (OCF) were used as control variables. The results show that better implementation of CG practices by the firms will help in increasing their efficiency. In other words, better CG practices help firms to utilize their resources in the better way to produce firm outputs (sales/Profit)
