Big Data Analytics in COVID-19
The COVID-19 epidemic has caused a large number of human losses and havoc in the economic, social, societal, and health systems around the world. Controlling such epidemic requires understanding its characteristics and behavior, which can be identified by collecting and analyzing the related big data. Big data analytics tools play a vital role in building knowledge required in making decisions and precautionary measures. However, due to the vast amount of data available on COVID-19 from various sources, there is a need to review the roles of big data analysis in controlling the spread of COVID-19, presenting the main challenges and directions of COVID-19 data analysis, as well as providing a framework on the related existing applications and studies to facilitate future research on COVID-19 analysis.

Cybersecurity Practices for Social Media Users
Cybersecurity is a collection of technologies established to protect the cyber environment of an individual user or organization. There are many cyber threats existing within the social media platform, such as loss of productivity, cyber bullying, cyber stalking, identity theft, social information overload, inconsistent personal branding, personal reputation damage, data breach, malicious software, service interruptions, hacks, and unauthorized access to social media accounts. It is also revealed that demographic factors, for example age, gender, and education level, may not necessarily be influential factors affecting the cyber awareness of the internet users.

Encyclopaedia Metallum
Encyclopaedia Metallum: The Metal Archives (commonly known as Metal Archives per the URL or just MA) is a website which lists bands from various forms of heavy metal music. Encyclopaedia Metallum was described by Matt Sullivan of Nashville Scene as "the Internet's central database for all that is 'tr00' in the metal world." Terrorizer described the site as "a fully-exhaustive list of pretty much every metal band ever, with full discographies, an active forum and an interlinking members list that shows the ever-incestuous beauty of the metal scene". Nevertheless, there are exceptions for bands which fall under disputed genres not accepted by the website. Encyclopaedia Metallum attempts to provide comprehensive information on each band, such as a discography, logos, pictures, lyrics, line-ups, biography, trivia and user-submitted reviews. The site also provides a system for submitting bands to the archives. The website is free of advertisements and is run completely independently.

Epiphany (Feeling)
An epiphany (from the ancient Greek ἐπιφάνεια, epiphanea, "manifestation, striking appearance") is an experience of a sudden and striking realization. Generally the term is used to describe scientific breakthrough, religious or philosophical discoveries, but it can apply in any situation in which an enlightening realization allows a problem or situation to be understood from a new and deeper perspective. Epiphanies are studied by psychologists and other scholars, particularly those attempting to study the process of innovation. Epiphanies are relatively rare occurrences and generally follow a process of significant thought about a problem. Often they are triggered by a new and key piece of information, but importantly, a depth of prior knowledge is required to allow the leap of understanding. Famous epiphanies include Archimedes's discovery of a method to determine the volume of an irregular object ("Eureka!") and Isaac Newton's realization that a falling apple and the orbiting moon are both pulled by the same force.

Areas of Mathematics
Mathematics encompasses a growing variety and depth of subjects over its history, and comprehension of it requires a system to categorize and organize these various subjects into more general areas of mathematics. A number of different classification schemes have arisen, and though they share some similarities, there are differences due in part to the different purposes they serve. A traditional division of mathematics is into pure mathematics; mathematics studied for its intrinsic interest, and applied mathematics; the mathematics that can be directly applied to real-world problems. This division is not always clear and many subjects have been developed as pure mathematics to find unexpected applications later on. Broad divisions, such as discrete mathematics, computational mathematics and so on have emerged more recently. An ideal system of classification permits adding new areas into the organization of previous knowledge, and fitting surprising discoveries and unexpected interactions into the outline. For example, the Langlands program has found unexpected connections between areas previously thought unconnected, at least Galois groups, Riemann surfaces and number theory.

Intraretinal Fluid Pattern Characterization
The accumulation of fluids in the retinal layers is one of the main causes of blindness in developed countries. The main strategy for its study and diagnosis is through the use of Optical Coherence Tomography (OCT) images. This allows experts to observe the layers of the retina in a cross-sectional view. Commonly, for the analysis of these accumulations by means of computer diagnostic support systems, precise segmentation strategies are employed.

Comparison Between Esperanto and Interlingua
Esperanto and Interlingua are two planned languages which have taken radically different approaches to the problem of providing an International auxiliary language (IAL). Although they are both classed as IALs, the intellectual bases of Esperanto and Interlingua are quite different. It has been argued that each language is a successful implementation of a particular IAL model. However, in both language communities there is a polemical tradition of using external criteria to critique the perceived opponent language (that is, judging Interlingua by Esperantist criteria and vice versa). In practical use, moreover, language usage in the two communities has sometimes shown convergences despite divergent theory.

Single-Letter Second-Level Domain
Single-letter second-level domains are domain names in which the second-level domain consists of only one letter, such as x.com. In 1993, the Internet Assigned Numbers Authority (IANA) explicitly reserved all single-letter and single-digit second-level domain names in the top-level domains com, net, and org, and grandfathered those that had already been assigned. In December 2005, ICANN considered auctioning these domains.
