Conflict-of-interest (COI) editing on Wikipedia refers to the situation where individuals edit articles about themselves, their organizations, or topics in which they have a personal stake or significant interest. This is considered problematic because it can lead to biased or unethical edits that do not adhere to Wikipedia's principles of neutrality and verifiability. Wikipedia encourages editors to disclose their conflicts of interest, rather than editing from a biased perspective.

Wikimedia censorship in mainland China refers to the restrictions imposed by the Chinese government on access to Wikimedia projects, including Wikipedia and Wikimedia Commons. This censorship is part of the broader internet censorship regime in China, commonly referred to as the "Great Firewall." Here are some key points about Wikimedia censorship in mainland China: 1. **Blocking of Sites**: Wikipedia, along with other Wikimedia projects, has been intermittently blocked in China.

An H II region is a large cloud of gas and dust in space that is ionized by the radiation from young, hot stars. The term "H II" refers to the presence of hydrogen ions (protons) in the region.

The Hillsborough disaster refers to a tragic event that occurred on April 15, 1989, at Hillsborough Stadium in Sheffield, England. It was a human crush during an FA Cup semi-final match between Liverpool and Nottingham Forest, resulting in the deaths of 97 Liverpool supporters and injuries to hundreds of others. The disaster is one of the worst sporting tragedies in British history.

MediaWiki is a free and open-source wiki software platform developed primarily for Wikipedia and other Wikimedia projects. It is written in PHP and uses a MySQL or MariaDB database to store its content. MediaWiki is designed to facilitate the collaborative creation and editing of content, allowing multiple users to create and modify pages easily. Key features of MediaWiki include: 1. **Version Control**: It keeps track of changes made to pages, allowing users to view and revert to previous versions if necessary.

Emergent evolution is a concept in evolutionary biology and philosophy that refers to the idea that new and complex forms of life or emergent properties can arise from simpler systems through evolutionary processes. This concept suggests that the whole is more than just the sum of its parts, and that certain properties or behaviors cannot be easily predicted by examining the individual components alone.

An icemaker, or ice maker, is a device that produces ice, either in a refrigerator or as a standalone appliance. There are several types of icemakers: 1. **Built-in Ice Makers**: These are often integrated into refrigerators or freezers. They can produce ice automatically and store it in a dedicated bin. They usually use a water line connected to the household plumbing.

An air ionizer is a device that uses high-voltage electricity to produce negative ions, which are molecules that have gained an extra electron. These negative ions can attach to positively charged particles in the air, such as dust, pollen, smoke, and other pollutants, causing them to clump together and fall to the ground or be attracted to surfaces. The primary purpose of an air ionizer is to improve indoor air quality by reducing airborne contaminants.

Home appliance manufacturers are companies that design, produce, and sell appliances intended for use in homes. These appliances are typically categorized into two main types: major appliances and small appliances. 1. **Major Appliances**: Also known as "white goods," these include large equipment used for cooking, cleaning, and preserving food.

Compactly supported homology is a version of homology theory that focuses on the study of spaces where the singular chains are required to have compact support. This concept is particularly useful in various areas of mathematics, including algebraic topology and differential geometry. ### Key Concepts: 1. **Homology**: Homology is a tool used in algebraic topology to study topological spaces by associating sequences of abelian groups (or modules) to them.

In category theory, a **cyclic category** typically refers to a category that captures the idea of cycles or circular structures. It can be viewed as a specialized type of category that includes objects and morphisms that relate to cyclical processes or relationships.

A domestic robot is a type of robot designed to assist with household tasks and activities. These robots are engineered to perform a variety of functions to help individuals manage their daily lives more effectively, improve convenience, and enhance quality of life within the home. Common examples of domestic robots include: 1. **Vacuum Robots**: Such as Roomba, which autonomously navigate and clean floors. 2. **Lawn Mowing Robots**: Devices that can cut grass with little to no human intervention.

A smart refrigerator is an advanced, Internet-connected appliance designed to enhance food storage and management through various smart technologies. These refrigerators typically offer several features that differentiate them from traditional models, including: 1. **Connectivity**: Smart refrigerators can connect to home Wi-Fi networks, allowing users to control and monitor them remotely via smartphone apps.

Homileticists are individuals who specialize in homiletics, which is the art and science of preaching and delivering sermons. This field involves the study of the principles and methods of preaching, focusing on how to effectively communicate biblical or theological messages to an audience. Homileticists may be theologians, pastors, or scholars who analyze various aspects of sermon preparation, structure, delivery, and the impact of sermons on congregations.

"Poema Morale" is a medieval poetic work attributed to the Italian poet Guido delle Colonne, written in the 13th century. It is a didactic poem that covers themes of morality, ethics, and the nature of virtue. The poem is notable for its allegorical approach, aiming to guide readers toward moral improvement and a better understanding of virtuous living, often referencing Christian symbolism and values.

The term "Postil" can refer to a couple of different concepts, depending on the context: 1. **Religious Commentary**: Traditionally, a "Postil" refers to a commentary on a portion of scripture. In the context of Christian literature, it often pertains to sermons or explanations of biblical texts that were intended for clergy or laypeople to better understand passages of the Bible.

"Telling the Truth" can refer to various concepts or works, depending on the context. Here are a few interpretations: 1. **Moral and Ethical Philosophy**: In a general sense, telling the truth pertains to the moral and ethical implications of honesty. It involves the idea of being transparent and accurate in communication, valuing integrity, and understanding the consequences of deception.

Hurewicz's theorem is a result in algebraic topology that pertains to the relationship between the homology and homotopy groups of a space. It specifically addresses the connection between the homology of a space and its fundamental group, particularly for spaces with certain properties.

The Kan-Thurston theorem is a result in the field of topology and geometric group theory, particularly concerning the relationships between 3-manifolds and the algebraic properties of groups. More specifically, it is related to the conjecture regarding the recognition of certain types of 3-manifolds and the structures of groups that can be associated with them.

Adams spectral sequences are a sophisticated tool used in algebraic topology and homotopy theory, particularly in the study of stable homotopy groups of spheres and related objects. They are named after Frank Adams, who developed the theory in the 1960s. Here's an overview of the key concepts associated with Adams spectral sequences: 1. **Spectral Sequences**: These are mathematical constructs used to compute homology or cohomology groups in a systematic way.
