Options Strategy
Option strategies are the simultaneous, and often mixed, buying or selling of one or more options that differ in one or more of the options' variables. Call options, simply known as calls, give the buyer a right to buy a particular stock at that option's strike price. Conversely, put options, simply known as puts, give the buyer the right to sell a particular stock at the option's strike price. This is often done to gain exposure to a specific type of opportunity or risk while eliminating other risks as part of a trading strategy. A very straightforward strategy might simply be the buying or selling of a single option, however option strategies often refer to a combination of simultaneous buying and or selling of options. Options strategies allow traders to profit from movements in the underlying assets based on market sentiment (i.e., bullish, bearish or neutral). In the case of neutral strategies, they can be further classified into those that are bullish on volatility, measured by the lowercase Greek letter sigma (σ), and those that are bearish on volatility. Traders can also profit off time decay, measured by the uppercase Greek letter theta (Θ), when the stock market has low volatility. The option positions used can be long and/or short positions in calls and puts.

All-points Bulletin
An all-points bulletin (APB) is an electronic information broadcast sent from one sender to a group of recipients, to rapidly communicate an important message. The technology used to send this broadcast has varied throughout time, and includes Teletype, Radio, Computerised Bulletin Board Systems (CBBS), and Internet. The earliest known record of the all-points bulletin is when used by American police, which dates the term to 1947. Although, used in the field of policing at the time, the APB has had usage in fields such as politics, technology and science research. However, since the 21st Century, due to advances in technology, all-points bulletins have become significantly less common and are now only primarily used by police departments in countries such as America, Canada, Australia and the United Kingdom.

Samsung Knox
Samsung Knox is a proprietary security and management framework pre-installed on most Samsung mobile devices. Its primary purpose is to provide organizations with a toolset for managing work devices, such as employee mobile phones or interactive kiosks. Knox provides more granular control over the standard work profile to manage capabilities found only on Samsung devices. Knox's features fall within three categories: data security, device manageability, and VPN capability. Knox also provides web-based services for organizations to manage their devices. Organizations can customize their managed mobile devices by configuring various functions, including pre-loaded applications, settings, boot-up animations, home screens, and lock screens. As of December 2020, organizations can use specific Samsung mobile device cameras as barcode scanners, using Knox services to capture and analyze the data.

Financial Technology Influence on the Banking Industry
The synthesis of technology and finance is known as financial technology (Fintech), which brings together two of the biggest industries in harmony. Fintech disruption is a deviation from the norm, resulting in a significant shift in banking services and, as a result, risk.

Differential Geometry of Curves
Differential geometry of curves is the branch of geometry that deals with smooth curves in the plane and in the Euclidean space by methods of differential and integral calculus. Starting in antiquity, many specific curves have been thoroughly investigated using the synthetic approach. Differential geometry takes another path: curves are represented in a parametrized form, and their geometric properties and various quantities associated with them, such as the curvature and the arc length, are expressed via derivatives and integrals using vector calculus. One of the most important tools used to analyze a curve is the Frenet frame, a moving frame that provides a coordinate system at each point of the curve that is "best adapted" to the curve near that point. The theory of curves is much simpler and narrower in scope than the theory of surfaces and its higher-dimensional generalizations, because a regular curve in a Euclidean space has no intrinsic geometry. Any regular curve may be parametrized by the arc length (the natural parametrization) and from the point of view of a theoretical point particle on the curve that does not know anything about the ambient space, all curves would appear the same. Different space curves are only distinguished by the way in which they bend and twist. Quantitatively, this is measured by the differential-geometric invariants called the curvature and the torsion of a curve. The fundamental theorem of curves asserts that the knowledge of these invariants completely determines the curve.

Morley's Trisector Theorem
In plane geometry, Morley's trisector theorem states that in any triangle, the three points of intersection of the adjacent angle trisectors form an equilateral triangle, called the first Morley triangle or simply the Morley triangle. The theorem was discovered in 1899 by Anglo-American mathematician Frank Morley. It has various generalizations; in particular, if all of the trisectors are intersected, one obtains four other equilateral triangles.

Quick Objects
Quick Objects is a powerful object–relational mapping tool for Microsoft .NET Framework with a built in framework for business logic and validation. The architecture for Quick Objects is different from other ORM tools (See: List of object–relational mapping software). Focus of Quick Objects to provide the advantages of code reuse, code generation and object relational mapping in a single tool set. Quick Objects API is very simple but packed with powerful features and capabilities. LINQ is fully supported and can be used against any of the supported databases. Classes generated by Quick Objects are ready for Web Services, Windows Communication Foundation and Remoting. Comprehensive data access and modification capabilities are complemented by a very flexible object model that allows the developer to specify and control every aspect of the CRUD operations. See below for a list of features.

Quietism
Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute, but rather that its value is in defusing confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates (particularly those between realists and non-realists) is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.
