Raft (Computer Science)
Raft is a consensus algorithm designed as an alternative to the Paxos family of algorithms. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features. Raft offers a generic way to distribute a state machine across a cluster of computing systems, ensuring that each node in the cluster agrees upon the same series of state transitions. It has a number of open-source reference implementations, with full-specification implementations in Go, C++, Java, and Scala. It is named after Reliable, Replicated, Redundant, And Fault-Tolerant. Raft is not a Byzantine fault tolerant algorithm: the nodes trust the elected leader.

Arbitrary-Oriented Object Detection in Aerial Images
Objects in aerial images often have arbitrary orientations and variable shapes and sizes. As a result, accurate and robust object detection in aerial images is a challenging problem.

Quantum Machine Learning for Security Assessment in IoMT
Internet of Medical Things (IoMT) is an ecosystem composed of connected electronic items such as small sensors/actuators and other cyber-physical devices (CPDs) in medical services. When these devices are linked together, they can support patients through medical monitoring, analysis, and reporting in more autonomous and intelligent ways.

Empathy in Virtual Reality Environments
The effectiveness of virtual reality (VR) in eliciting empathy lies in the fact that VR offers possibilities for situating people in a specific context and in the shoes of others. Previous research has investigated the benefits of VR in eliciting empathy and has compared VR with other technologies.

Canadian Internet Registration Authority
The Canadian Internet Registration Authority (CIRA) (French: Autorité canadienne pour les enregistrements Internet ACEI) is the organization that manages the .ca country code top-level domain (ccTLD) for Canada. Its offices are located at 979 Bank Street in Ottawa, Ontario, Canada. CIRA sets the policies and agendas that support Canada's Internet community and Canada's involvement in international Internet governance. It is a member-driven organization with membership open to all that hold a .ca domain. As of May 2020, there were more than 2.9 million active .ca domains.

Flatfeet Severity-Level Detection
Flat foot is a postural deformity in which the plantar part of the foot is either completely or partially contacted with the ground. In the clinical practices, X-ray radiographs have been introduced to detect flat feet because they are more affordable to many clinics than using specialized devices.

Artificial Intelligence in the Diagnosis of Dairy Cows
With the rapid growth of computational power and data transfer capabilities, machine learning (ML) and artificial intelligence (AI) are also making inroads into animal husbandry and veterinarian research. In particular, Infrared thermography (IRT) is being increasingly used for health monitoring and the diagnosis of dairy cows, especially in studies related to heat stress, which causes severe losses, helping us analyze its effects on nutrition, milk production, reproduction, etc. There is plenty of evidence for the potential benefits of using IRT for monitoring udder health status in dairy cows and for the early detection of mastitis. Its role in detecting hoof lesions and lameness has also been reported. The growth of the population and the increase of quality standards has set a requirement for the production of more and better quality food. The capabilities and potential benefits of IRT make systems for the automatic collection and processing of thermographic information and decision-making particularly important.

International Workshop on Operator Theory and Its Applications
The other major branch of operator theory, Operator algebras (C* and von Neumann Algebras), is not heavily represented at IWOTA and has its own conferences. IWOTA gathers leading experts from all over the world for an intense exchange of new results, information and opinion, and for tracing the future developments in the field. The IWOTA meetings provide opportunities for participants (including young researchers) to present their own work in invited and contributed talks, to interact with other researchers from around the globe, and to broaden their knowledge of the field. In addition, IWOTA emphasizes cross-disciplinary interaction among mathematicians, electrical engineers and mathematical physicists. In the even years, the IWOTA workshop is a satellite meeting to the biennial International Symposium on the Mathematical Theory of Networks and Systems (MTNS). From the humble beginnings in the early 80's, the IWOTA workshops grew to become one of the largest continuing conferences attended by the community of researchers in operator theory.

Unbalanced Oil and Vinegar
In cryptography, the Unbalanced Oil and Vinegar (UOV) scheme is a modified version of the Oil and Vinegar scheme designed by J. Patarin. Both are digital signature schemes. They belong to the group of multivariate cryptography. The security of this signature scheme is based on an NP-hard mathematical problem. To create and validate signatures a minimal quadratic equations system must be solved. Solving m equations with n variables is an NP-hard problem, which means the problem is almost certainly difficult to solve efficiently in the worst case, even when using a quantum computer. While the problem is easy if m is either much much larger or much much smaller than n, importantly for cryptographic purposes, the problem is thought to be difficult in the average case when m and n are nearly equal, even when using a quantum computer. As a result, a number of signature schemes have been devised based on multivariate equations with the goal of achieving quantum resistant signatures.
