Fair and trustworthy: Lock-free enhanced tendermint blockchain algorithmTELKOMNIKA JOURNAL
Blockchain Technology is exclusively used to make online transactions secure by
maintaining a distributed and decentralized ledger of records across multiple computers.
Tendermint is a general-purpose blockchain engine that is composed of two
parts; Tendermint Core and the blockchain application interface. The application interface
makes Tendermint suitable for a wide range of applications. In this paper, we
analyze and improve Practical Byzantine Fault Tolerant (PBFT), a consensus-based
Tendermint blockchain algorithm. In order to avoid negative issues of locks, we first
propose a lock-free algorithm for blockchain in which the proposal and voting phases
are concurrent whereas the commit phase is sequential. This consideration in the algorithm
allows parallelism. Secondly, a new methodology is used to decide the size
of the voter set which is a subset of blockchain nodes, further investigating the block
sensitivity and trustworthiness of nodes. Thirdly, to fairly select the voter set nodes,
we employ the random walk algorithm. Fourthly, we imply the wait-freedom property
by using a timeout due to which all blocks are eventually committed or aborted. In
addition, we have discussed voting conflicts and consensuses issues that are used as a
correctness property, and provide some supportive techniques.

Approximation-based homomorphic encryption for secure and efficient blockcha...IJECEIAES
Homomorphic encryption has been widely used to preserve the privacy of watermarking process on blockchain-driven watermarking services. It offers transparent and traceable encrypted watermarking without revealing sensitive data such as original images or watermark data to the public. Nevertheless, the existing works suffer from enormous memory storage and extensive computing power. This study proposed an approximation-based homomorphic encryption for resource-efficient encrypted watermarking without sacrificing watermarking quality. We demonstrated the efficiency of the Cheon-KimKim-Son (CKKS) encrypted watermarking process using discrete cosine transform-singular value decomposition (DCT-SVD) embedding. The evaluation results showed that it could preserve the watermarking quality similar to non-encrypted watermark embedding, even after geometrical and filtering attacks. Compared to existing homomorphic encryption, such as BrakerskiGentry-Vaikuntanathan (BFV) encryption, it has superior performance regarding resource utilization and watermarking quality preservation

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
