Overtone musicians are artists who specialize in overtone singing, a vocal technique that involves producing multiple pitches simultaneously. This practice is found in various cultures around the world, particularly in Central Asia, but has also gained popularity in contemporary music genres.

Overtone singing, also known as throat singing or harmonic singing, is a vocal technique that allows a singer to produce multiple pitches simultaneously. This technique involves manipulating the resonances created in the vocal tract to emphasize certain overtones, creating a sound that is rich in harmonics. The fundamental pitch produced is often accompanied by one or more higher pitches, which can be clearly heard and controlled.

The Ginzburg criterion, often referenced in the context of superconductivity, provides a condition for determining the stability of a superconducting state. Specifically, it assesses the ability of a superconducting material to maintain its superconducting properties under the influence of external magnetic fields or current. The Ginzburg criterion is associated with the Ginzburg-Landau (GL) theory, which is a theoretical framework used to describe superconductivity.

"Discourse on the Tides" is not a widely recognized term or title in conventional literature, philosophy, or scholarship, as of my last update in October 2023. It could potentially refer to a specific text, artistic work, or concept that has emerged recently or may be related to themes of change, movement, or the philosophical implications of tides—common metaphors in discussions about human experience, nature, or societal shifts.

Horizontal Falls, often referred to as "Horizontal Falls" or "Horizontal Waterfalls," is a unique natural phenomenon located in the Kimberley region of Western Australia. It is not a waterfall in the traditional sense but rather a tidal change that creates the illusion of a waterfall. The phenomenon occurs in the definitely narrow gap between two cliffs that connects two enclosed bodies of water.

Multivariate time series refers to a collection of multiple time series data points collected or observed over time. Unlike univariate time series, which involves a single variable or feature analyzed at different time points, multivariate time series consists of two or more variables that may be related to each other. This relationship can help to identify patterns, correlations, or dynamics that wouldn't be evident from analyzing each time series independently.

Tidal prism refers to the volume of water that is exchanged between a tidal body of water, such as an estuary or a coastal bay, and the open sea during a tidal cycle. It is the difference in water volume between high tide and low tide in a specific location. Tidal prism can be calculated by measuring the area of the water body and the change in water level (i.e., the tidal range) during the tidal cycle.

"Between the Strokes of Night" is a novel by the author and playwright Charles B. McKenzie. The story generally explores themes such as the passage of time, human experience, and the intersection of dreams and reality. The narrative weaves in elements of suspense and introspection, often delving into the complexities of relationships and the human psyche.

Klangfarbenmelodie is a musical term that originated in the early 20th century, particularly associated with composers of the Second Viennese School, such as Arnold Schoenberg. The term translates from German as "tone color melody" or "sound color melody." It refers to a compositional technique in which the musical qualities of timbre (the character or quality of a musical sound) are emphasized alongside traditional melody.

"The New Policeman" is a children's novel written by Irish author Kate Thompson, published in 2005. The story revolves around a young boy named J.J. Liddy, who lives in a small Irish village. As he discovers that time is running out in his world, he embarks on a fantastical journey that intertwines music, folklore, and adventure, linking contemporary life with Irish mythology.

"Ubik" is a science fiction novel written by Philip K. Dick, first published in 1969. The story is set in a future where telepathy and precognition are common, and it explores themes of reality, identity, and the nature of existence. The plot follows a group of "ininside" agents who work in a world where commercial telepathy is commonplace, and they are involved in a conflict over corporate interests.

A **string graph** is a type of intersection graph that can be constructed from a collection of continuous curves (strings) in a two-dimensional space. More formally, a string graph is defined as the graph whose vertices correspond to these curves, and there is an edge between two vertices if and only if the corresponding curves intersect at some point in the plane.

Chain linking is a method used in various fields, primarily in economic statistics and time series analysis, to connect different data points or measurements over time to create a more continuous series of data. It allows for the adjustment of data to reflect changes in price levels or quantities, enabling better comparisons across different periods. In the context of economics, chain linking often refers to the way that real GDP (Gross Domestic Product) or other economic indicators are calculated to account for inflation.

Exponential smoothing is a statistical technique used for forecasting time series data. It involves using weighted averages of past observations, with the weights decaying exponentially. This means that more recent observations have a greater influence on the forecast than older observations. Exponential smoothing is particularly useful for data with trends and seasonal patterns. There are several types of exponential smoothing methods, including: 1. **Simple Exponential Smoothing**: This method is used for time series data without trends or seasonal patterns.

Mean Absolute Scaled Error (MASE) is a metric used to evaluate the accuracy of forecasting methods. It provides a scale-free measure of forecasting accuracy, making it useful for comparing forecast performance across different datasets and scales.

The order of integration refers to the number of times a function has been integrated. In calculus, the process of integration can be performed multiple times, and each layer of integration adds to the "order." Here’s a brief breakdown of the concept: 1. **First Order Integration**: This is the process of integrating a function once.

Smoothing is a statistical technique used to reduce noise and variability in data to reveal underlying patterns or trends. It is commonly applied in various fields, such as signal processing, time series analysis, data visualization, and machine learning. The goal of smoothing is to make the important features of the dataset more apparent, allowing for clearer insights and analysis.

Kronecker's theorem, also known as the Kronecker limit formula, is a result in number theory specifically related to the distribution of prime numbers and the behavior of certain algebraic objects. It can be particularly focused on the context of the theory of partitions or modular forms, but the term might refer to different results depending on the field.

"More of Tom Lehrer" is a comedy album by the American singer-songwriter and mathematician Tom Lehrer, released in 1961. It is part of his collection of musical works that often feature satirical songs addressing various social, political, and philosophical themes. This album includes some of Lehrer’s well-known songs, showcasing his clever lyrics and distinctive style that blend humor with sharp wit.

Tonka Films, often associated with the Tonka brand, is a division known for producing children's television shows and films. The Tonka name is primarily recognized for its line of toy trucks and construction vehicles, which have been popular for decades. In the context of film and media, Tonka Films produced animated series and movies that featured characters and themes appealing to children, often tied to the adventurous spirit of the Tonka toys.
