Digital-Twins-Based Internet of Robotic Things for Remote Health Monitoring of COVID-19 Patients
The deadly coronavirus disease (COVID-19) has highlighted the importance of remote health monitoring (RHM). The digital-twins (DTs) paradigm enables RHM by creating a virtual replica that receives data from the physical asset, representing its real-world behavior. However, DTs use passive Internet of Things (IoT) sensors, which limit their potential to a specific location or entity. This problem can be addressed by using the Internet of Robotic Things (IoRT), which combines robotics and IoT, allowing the robotic things (RTs) to navigate in a particular environment and connect to IoT devices in the vicinity. Implementing DTs in IoRT, creates a virtual replica [virtual twin (VT)] that receives real-time data from the physical RT [physical twin (PT)] to mirror its status. However, DTs require a user interface for real-time interaction and visualization. Virtual reality (VR) can be used as an interface due to its natural ability to visualize and interact with DTs. This research proposes a real-time system for RHM of COVID-19 patients using the DTs-based IoRT and VR-based user interface. It also presents and evaluates robot navigation performance, which is vital for remote monitoring. The VT operates the PT in the real environment (RE), which collects data from the patient-mounted sensors and transmits it to the control service to visualize in VR for medical examination. The system prevents direct interaction of medical staff with contaminated patients, protecting them from infection and stress. The experimental results verify the monitoring data quality (accuracy, completeness, and timeliness) and high accuracy of PT's navigation.- Qatar National Library

Evaluation of stress and its clinical correlation among the students of Allied Health Sciences
Background: Stress is a key indicator affecting the psychological and physical health of students throughout the world. The current study was planned to find out depression, stress, and anxiety and their impact on obesity and different clinical markers among the students of Allied Health Sciences.Methods: To assess stress, anxiety, and depression levels; the Depression, Anxiety, and Stress Scale (DASS- 21) was utilized. A total of 1446 individuals participated in the current research project. After assessing the BMI of students, a blood sample of two hundred and two (202) obese students were collected. Spectrophotometry, latex agglutination, and flow cytometry were employed to determine the different clinical markers.Results: Stress was found in 63.10% population, while depression was 59.70% and the prevalence of anxiety was 61.90%. After analysis of the blood samples of students, a significant increase was seen in cholesterol and HDL, while VLDL was moderately decreased. LDL, triglycerides, and CBC showed no significant change. Random blood glucose was normal, and CRP was also found negative in all the participants. There was no significant correlation between serum lipid profile and CBC parameters during stress, anxiety, and depression in students.Conclusion: A significant stress level was found among the students of Allied Health Sciences. It is a dire need of time to be focused on the mental health of students. Psychological counseling should be provided in the institutes for the mental well-being of the students.Keywords: Stress, Depression, Anxiety, Dass-21, Health sciences students
Comparison of nutrients uptake in different varieties of rice in Pakistan
The objective of this research was to determine the uptake of different elements (K, Mg, Ca, Na, Fe, Co, Mn, Pb, Cu, Zn and Ni) which are used as nutrients by the rice crop. Different types of rice seeds KSK-282, KSK-134, BAS-515, IR6, BAS-2000, KSK-133 and super-BAS were collected from National Agricultural Research Centre (NARC) Islamabad Pakistan and grown in different plastic pots containing soil under the same condition. Ten days old immature plants of different varieties of rice were dried and their roots were separated from the whole plants. The dried roots were ground into fine powder followed by acid digestion (HNO , H SO and 3 2 4 HClO ) solution in a ratio of (5:1:0.1) individually. After digestion the solutions were filtered and the filtrates 4 were diluted by adding distilled water. The diluted solutions of all the above mentioned varieties of rice were analyzed by Atomic Absorption Spectrophotometer (AAS) for nutrients (K, Mg, Ca, Na, Fe, Co, Mn, Pb, Cu, Zn and Ni) concentration. The different values obtained from AAS had shown that some rice varieties had taken up nutrients (elements) in large amount (e.g., KSK-134 had taken up maximum Fe while KSK-133 had taken up minimum) as compared to other varieties. Similarly, several verities absorbed comparatively minimum concentration of elements. The results obtained in this research work clearly indicated that the absorption of these elements from the soil was dependent on the rice variety (e.g., BAS-2000 absorbed maximum Mg while minimum Super-BAS). Interestingly most of the rice vaities had absorbed the beneficial elements in large quantity as compared to other toxic elements

التفاؤل والتشاؤم في أدب العصرالجاهلي والعصرالإسلامي (دراسة موازنة): Optimism and pessimism in the literature of the pre-Islamic era and the Islamic era (A Comparative study)
There are two types of people: a desperate pessimist who faces the challenges of life with defeat, flight and surrender, and an optimistic hopeful who faces them with patience and struggle, courage and daring, and confidence in victory. And many manifestations of mental illness. Optimists live a stable life together, expect goodness, look at events and situations with moderation and balance, and search for opportunities more than they search for problems. Optimism is needed by the average individual as well as needed by leaders and messengers.
The Arabs used to have pessimism and superstition, and they expected evil when they saw material manifestations, which they interpreted as such, when someone saw a black bird, for example, or when a man with a disability and illness greeted him, or when the bird headed to the north..., those beliefs that may have diverted a person from his travel , or about a need from its needs. Islam came and nullified these manifestations. Therefore, this research sheds light on optimism and pessimism in the literature of the pre-Islamic and Islamic era (the beginning of Islam and the Umayyads).
Key words: desperate, pessimist, challenges, surrender, manifestation
A Synopsis of Perspectives on (United Nations) Peace Operations from Theories of International Relations
The post-Cold War era witnessed a significant increase in the size and scope of peace operations. However, the role and purpose of peace operations have not received commensurate attention within the intellectual context of theories of international relations. Comprehension of theoretical foundations of international relations is quintessential in understanding the motives behind and implications of third-party intervention in the quest for viable peace. This paper presents a synopsis of major theoretical paradigms in world politics with particular emphasis on their understanding of and implications for contemporary peace operations. The paper strives to delineate the central planks of a particular theoretical paradigm with special reference to the underpinnings of peace operations. Towards the end, the prospect of training peacekeepers to bridge the theory and practice of peace operations has been explored. The research findings shall fill a theoretical gap in peace operations studies and decipher the theoretical basis of the acerbic arguments against peace operations espoused by the obstructionists to the peace processes
تعقبات الشيخ الإثيوبي العلمية لأهل العلم في كتابه "إتحاف الطالب الأحوذى" 1- )دراسة نقدية)
Al-Sheikh Athioubi (R.A) is one of those great Islamic scholars who commented on and corrected the quotes and sayings of great Hadith scholars. He has written a comprehensive and detailed commentary on the books of hadiths, including the "Ithaaf Ul Talib Al-Ahuzi." In this book, he pursued the opinions of various scholars, in which there were weaknesses and a lack of arguments for their opinions. He had a unique methodology for his critical analysis of these scholars, such as quoting their sayings and studying them in depth. If he found any defects in these sayings, he tried to show them and brought the correct statement about these defections. So it is crucial to elaborate on his methodology, like what the basis is for him to critique others. Here one can find in his approach attributional issues to judge the Hadith, the connection and disconnection in the attribution, errors in the name of the narrator, and issues related to Islamic Fiqh and Jurisprudence. This research paper will try to explain and critically analyze the major points in the methodology of Al-Athioubi

The contemplative tendency in Classical Arabic Literature
Arabic Poetry contains deep thoughtfulness, contemplative tendency and wisdom and this wisdom will be derived from Arabic Poetry with full attention and thoughtfulness. The Poets of Arabic language got a remarkable position in the poetry. Just as Zuhair bin Abisulma, he says that i have the knowledge of today and yesterday but i don't know anything about tomorrow and this statement contains very wisdom. The Arabic language is still preserved in its orignal shape due to religious and poetic Literature. As Al-Zir Salem was killed by his two slaves in desert, he told them before his death that these two verses of poetry should be told to my family.
من مبلغ الحيين أَنّ مُهلهلا لله دركما ودر أبيكما
When the slaves killed him and told these lines to his family his niece said that this is incomplete. This may be like that:
من مبلغ الحيين أَنّ مُهلهلا أضحى قتيلاً في الفلآة مجندلا
لله دركما ودرّ أبيكما لا يبرح العبدان حتى يقتـلا
And told to the slaves that you have killed our father and they were arrested. Where as now a days we use modern technological equipment for investigation but in that days the poetry was used as investigation tool and this is all due to its deep thoughts that not every person understand the basic meaning and concept but only wise and thoughtful people can derive the actual meaning from it.
Like that once the poet asked someone regarding his tribe he answered in one line of poetry about his tribe with characteristics:
ومهفهف كالغصن قلت له انتسب فأجاب ما قتل المحبّ حرام
Now he describes his complete tribe on the basis of one word that is "ما".that he is from banu tamim tribe of Arab because they use "ما" like that. It is a code language which can be uncoded by deep thoughtfulness. In this research article we will proves the deep thoughtfulness of Arabic language and Arabic poets.http://www.al-azhaar.org/index.php/alazhar/article/view/41
3D convolutional neural networks based automatic modulation classification in the presence of channel noise
Automatic modulation classification is a task that is essentially required in many intelligent communication
systems such as fibre-optic, next-generation 5G or 6G systems, cognitive radio as well as multimedia internet-ofthings networks etc. Deep learning (DL) is a representation learning method that takes raw data and finds
representations for different tasks such as classification and detection. DL techniques like Convolutional Neural
Networks (CNNs) have a strong potential to process and analyse large chunks of data. In this work, we considered the problem of multiclass (eight classes) classification of modulated signals, which are, Binary Phase Shift Keying, Quadrature Phase Shift Keying, 16 and 64 Quadrature Amplitude Modulation corrupted by Additive White Gaussian Noise, Rician and Rayleigh fading channels using 3D-CNN architectures in both frequency and spatial domains while deploying three approaches for data augmentation, which are, random zoomed in/out, random shift and random weak Gaussian blurring augmentation techniques with a cross-validation (CV) based hyperparameter selection statistical approach. Simulation results testify the performance of 10-fold CV without augmentation in the spatial domain to be the best while the worst performing method happens to be 10-fold CV without augmentation in the frequency domain and we found learning in the spatial domain to be better than learning in the frequency domain.National Natural Science Foundation of China,
