Blockchains and Artificial Intelligence
It is undeniable that the adoption of blockchain- and artificial intelligence (AI)-based paradigms is proceeding at lightning speed. Both paradigms provide something new to the market, but the degree of novelty and complexity of each is different. In the age of digital money, blockchains  may automate installments to allow for the safe, decentralized exchange of personal data, information, and logs. AI and blockchains are two of the most talked about technologies right now. Using a decentralized, secure, and trustworthy system, blockchain technology can automate bitcoin payments and provide users access to a shared ledger of records, transactions, and data. Through the use of smart contracts, a blockchain may also regulate user interactions without the need for a central authority. As an alternative, AI provides robots with the ability to reason and make decisions and human-level intellect.

IoT Intrusion Detection Using Feature Selection Method
The Internet of Things (IoT) ecosystem has experienced significant growth in data traffic and consequently high dimensionality. Intrusion Detection Systems (IDSs) are essential self-protective tools against various cyber-attacks. However, IoT IDS systems face significant challenges due to functional and physical diversity. These IoT characteristics make exploiting all features and attributes for IDS self-protection difficult and unrealistic.

Network Function Virtualization and Service Function Chaining Frameworks
Network slicing has become a fundamental property for next-generation networks, especially because an inherent part of 5G standardisation is the ability for service providers to migrate some or all of their network services to a virtual network infrastructure, thereby reducing both capital and operational costs. With network function virtualisation (NFV), network functions (NFs) such as firewalls, traffic load balancers, content filters, and intrusion detection systems (IDS) are either instantiated on virtual machines (VMs) or lightweight containers, often chained together to create a service function chain (SFC).

Stencil Code
Stencil codes are a class of iterative kernels which update array elements according to some fixed pattern, called a stencil. They are most commonly found in the codes of computer simulations, e.g. for computational fluid dynamics in the context of scientific and engineering applications. Other notable examples include solving partial differential equations, the Jacobi kernel, the Gauss–Seidel method, image processing and cellular automata. The regular structure of the arrays sets stencil codes apart from other modeling methods such as the Finite element method. Most finite difference codes which operate on regular grids can be formulated as stencil codes.

Bayonetta
Bayonetta is an action hack and slash video game developed by PlatinumGames and published by Sega. The game was originally released for Xbox 360 and PlayStation 3 in Japan in October 2009, and in North America and Europe in January 2010. The game was later released on the Wii U alongside its sequel, Bayonetta 2, releasing in September 2014 in Japan and worldwide the following month - the two games were later released worldwide on the Nintendo Switch in February 2018. An enhanced port for Windows was released in April 2017 with 4K support. A remastered version of Bayonetta as well as another PlatinumGames title, Vanquish, was released for PlayStation 4 and Xbox One on February 18, 2020, as part of a compilation to celebrate the 10th anniversary of the game. Bayonetta takes place in Vigrid, a fictional city in Europe. The game stars the eponymous character, a witch who is capable of shapeshifting and using various firearms. She possesses magical attacks, and she can use her hair to summon demons to dispatch her foes. It features a rating system, which gives players a grade based on their performance, and a combat system that is similar to the Devil May Cry series. Development of the game was started in January 2007, with Hideki Kamiya being the game's director. According to Kamiya, the game was completely original, though he drew some inspirations from Scandinavian mythology, and played Devil May Cry 4 for reference. The game's theme is "sexiness" and "partial nudity", and that the characters were designed to be "fashionable". Kamiya and artist Mari Shimazaki spent more than a year to create Bayonetta's design. Several demos were released for the game prior to its launch. Bayonetta was the third project released by PlatinumGames, which was founded by former Clover Studio employees. Upon release, the game received generally positive reviews. The game was praised for its combat, presentation and soundtrack, but drew criticism for its story and quick time events. Bayonetta was nominated for and won several end-of-the-year accolades, and had sold over a million units worldwide by 2010. An anime film adaptation of the game by Gonzo, titled Bayonetta: Bloody Fate, was released in Japan in November 2013. A third game, Bayonetta 3, is in development for the Switch.

ADM-3A
The ADM-3A was an influential early video display terminal, introduced in 1976. It was manufactured by Lear Siegler and had a 12-inch screen displaying 12 or 24 lines of 80 characters. It set a new industry low single unit price of $995. Its "dumb terminal" nickname came from some of the original trade publication advertisements. It quickly became commercially successful because of the rapid increase of computer communications speeds, and because of new minicomputer systems released to the market which required inexpensive operator consoles.

Wi-Fi
Indoor positioning poses a number of challenges as several effects, such as signal attenuation, signal fluctuations, interference, and multipath occur in signal propagation. The severity depends on the method and technology adopted to perform user localization. Wi-Fi is a popular method because of its ubiquity with already available public and private infrastructure in many environments and the ability for mobile clients, such as smartphones, to receive these signals.

Public Interest Registry
Public Interest Registry is a Reston, Virginia-based not-for-profit created by the Internet Society in 2002 to manage the .ORG top-level domain. It took over operation of .ORG in January 2003 and launched the .NGO and .ONG top-level domains in March 2015. In November 2019, it was announced the Public Interest Registry would be sold by the Internet Society to private equity investment firm Ethos Capital for 1.135 billion USD, but in April 2020, ICANN decided to reject the sale.

Localization (Algebra)
In commutative algebra and algebraic geometry, the localization is a formal way to introduce the "denominators" to a given ring or module. That is, it introduces a new ring/module out of an existing one so that it consists of fractions such that the denominator s belongs to a given subset S of R. The basic example is the construction of the ring Q of rational numbers from the ring Z of rational integers. The technique has become fundamental, particularly in algebraic geometry, as it provides a natural link to sheaf theory. In fact, the term localization originates in algebraic geometry: if R is a ring of functions defined on some geometric object (algebraic variety) V, and one wants to study this variety "locally" near a point p, then one considers the set S of all functions which are not zero at p and localizes R with respect to S. The resulting ring R* contains only information about the behavior of V near p. Cf. the example given at local ring. An important related process is completion: one often localizes a ring/module, then completes. In this article, a ring is commutative with unity.
