 Abstract

Identifying message sources in social networks plays a critical role in limiting the damage caused by them through the timely quarantine of the sources. However, the temporal variation in the topology of social networks and the ongoing dynamic processes challenge our traditional source identification techniques that are considered in static networks. In this paper, we borrow an idea from criminology and propose a novel method to overcome the challenges. First, we reduce the time-varying networks to a series of static networks by introducing a time-integrating window. Second, instead of inspecting every individual in traditional techniques, we adopt a reverse dissemination strategy to specify a set of suspects of the real message source. This process addresses the scalability issue of source identification problems, and therefore dramatically promotes the efficiency of message source identification. Third, to determine the real source from the suspects, we employ a novel microscopic message spreading model to calculate the maximum likelihood (ML) for each suspect. The one who can provide the largest ML estimate is considered as the real source. The evaluations are carried out on real social networks with time- varying topology. The experiment results show that our method can reduce 60% - 90% of the source seeking area in various time-varying social networks. The results further indicate that our method can accurately identify the real source, or an individual who is very close to the real source. To the best of our knowledge, the proposed method is the first that can be used to identify message sources in time-varying social network

 Abstract

The process of Reproduction is natural and bearing a child is essential for any creature in this world to claim their existence. Generally every couple wants to give birth of their child but sometimes they are failure due to several causes like the problem of infertility, critical health issues, and some time it's biologically impossible. Nowadays infertility becomes a great problem that women have to face and in our Indian society a woman who has not a child is considered as an incomplete and inauspicious for any good social ritual. She has to tolerate undeserved comments and sometimes received worst behavior from society and even from her family members. Sometimes men have to face the same problem and in this way they are emotionally tortured by the society. So here it can be said that surrogacy is a new hope for these couples. Surrogacy is a contract between a fertile women and infertile couple or intended parent(s), where a fertile woman ready to give birth child on the behalf of intended parent(s). Generally on the basis of contract we found two types of surrogacy Altruistic surrogacy and Commercial surrogacy. Among this especially Commercial surrogacy is badly involved many ethical and legal issues. But here on this article I am going to discuss another ethical perspective from need based point of view. It helps us to rethinking about the ethical issues of surrogacy.

 Abstract

In the current study, a framework is presented that makes use of a dataset of housing prices from various areas of Mumbai as well as important variables like the property's location, size, and existence of a swimming pool, among others. The information came from Kaggle Inc. Based on the aforementioned parameters, the technique is intended to predict the resale price of a property. An ensemble learning technique was used to improve prediction accuracy by mixing numerous machine learning algorithms rather of relying just on one. In order to provide a more accurate prediction result than utilising only one method, the ensemble model used in the study integrates Decision Tree, Linear Regression, and K-Nearest Neighbour algorithms. The system achieves the lowest predicting error with the use of this ensemble model, with the trained model showing a Mean Absolute Percentage Error (MAPE) of 16.09%.

 Abstract

The art or practise of hiding a message, image, or file within another message, image, or file is known as steganography. This essay examines how images on the institution's network can be used to hide papers within that organisation. The C programming language was used to create this free, self-contained, and user-friendly application. Before the document is delivered through the institution's network to the intended recipient, the encryption procedure is carried out on the user's computer. Images are encrypted and decrypted during this procedure, preventing hackers or casual users from reading documents that weren't created for them.

 Abstract

The social dignity and position of women was very favourable for them during the Rig Vedic India. They lost their freedom during the later Vedic period. They enjoyed maximum freedom during the Sangam Age that was the Dravidian civilization. They began to be enjoyed rights and freedom during the British period. Now they are more aware about their freedom and civic rights through Missionary Education, wealth and higher positions.

 Abstract

Pain is defined by The International Association for the Study of Pain (IASP) as "an unpleasant sensory and emotional experience related to or described in actual or potential tissue damage". In emergency rooms, 60% of patients experience acute pain and in 85% of cases, pain is the main reason for consultation. The fight against pain is a public health priority. The establishment of national guidelines and recommendations testifies to the institutional will and of health professionals to optimize their management. The organizational and structural impact as well as human resources are major determinants in the success of any pain management strategy, especially in emergencies, both symptomatic and etiological. As a result, we carried out work within the emergency admissions department of the tertiary hospital to take stock of analgesia practices as well as the epidemiological and clinical characteristics of the patients concerned. This is a prospective single-center, analytical cross-sectional study carried out over 3 months in an emergency department of a tertiary hospital in Casablanca.

 Abstract

The basal metabolic rate is reduced in hypothyroidism because the thyroid gland does not produce enough thyroid hormones. The major job of thyroxine is to support oxidative metabolism by acting as a catalyst. These roles are comparable to how Agni is described in Ayurveda. Agni (jatharagni, bhutagni, and dhatvagni) regulates all bodily metabolic processes. Jatharagnimandya results in dhatwagnimandya since dhatwagni depends on jatharagni. Although hypothyroidism is not directly described in Ayurveda, it can be linked to dhatwagnimandya (ras and meda dhatwagnimandya) based on its clinical manifestation. The health and altered condition of Agni might be related to the normal and abnormal function of the thyroid gland. The relationship between hypothyroidism and Agnimandhya is highlighted in this article.

 Abstract

With the widespread adoption of cloud computing, securing data and ensuring continuous authentication of devices accessing cloud services has become a critical concern. Traditional cryptographic methods, while effective, are vulnerable to quantum computing attacks that can compromise security. To address this challenge, we propose a novel device-to-device continuous authentication protocol for cloud services, leveraging the principles of quantum cryptography.Our proposed protocol utilizes quantum key distribution (QKD) to establish secure and authenticated communication channels between devices accessing cloud services. QKD leverages the principles of quantum mechanics, such as the Heisenberg uncertainty principle and quantum entanglement, to securely generate and distribute cryptographic keys, which are immune to attacks from quantum computers. The protocol continuously authenticates the devices by periodically exchanging quantum keys, verifying their authenticity and integrity, and updating the keys accordingly.Our protocol ensures secure and continuous authentication of devices accessing cloud services, protecting against various attacks including man-in-the-middle attacks, replay attacks, and eavesdropping attacks. It provides strong security guarantees, leveraging the unique properties of quantum mechanics to protect against attacks from both classical and quantum computers. Moreover, our protocol reduces the need for centralized authentication servers, reducing the risk of single point of failure and enhancing the scalability and efficiency of cloud services.We evaluate our proposed protocol through extensive simulations and performance analysis, demonstrating its effectiveness in ensuring secure and continuous authentication of devices accessing cloud services. Our findings highlight the potential of quantum cryptography as a promising solution for securing cloud computing environments and enabling secure device-to-device communication.
