Announced alongside Half-Life 2: Episode One in 2006, Episode Three was intended to continue the story of protagonist Gordon Freeman and his struggle against the oppressive Combine forces, picking up where Episode Two left off.
The Quantum Anomalous Hall Effect (QAHE) is a phenomenon in condensed matter physics that occurs in certain materials, particularly topological insulators and ferromagnetic systems with strong spin-orbit coupling. It is a quantum version of the classical Hall effect, wherein an electric current flowing in a two-dimensional conductor generates a transverse voltage in the presence of a magnetic field.
SMART-1, which stands for Small Missions for Advanced Research and Technology, was a European Space Agency (ESA) spacecraft that was launched on September 27, 2003. It was primarily designed as a technology demonstration mission to test various new technologies for future spacecraft.
The Thermal Hall effect, often referred to as the "thermal Hall effect" or "thermal Hall conductivity," describes a phenomenon related to the transport of heat in a material subjected to a temperature gradient in the presence of a magnetic field. In a typical scenario, when a temperature difference is established across a material (for example, by heating one side), heat flows from the hot side to the cold side.
CCR4-Not is a multi-protein complex that plays a crucial role in various cellular processes related to gene regulation, mRNA metabolism, and RNA decay. The name "CCR4-Not" derives from its two main components: the CCR4 deadenylase complex and the Not complex. 1. **CCR4 Complex**: This component primarily functions in the deadenylation of mRNA.
The Sapphic stanza is a poetic form derived from the works of the ancient Greek poet Sappho. It is characterized by its specific metrical structure, typically consisting of three lines of eleven syllables followed by a fourth line of five syllables, often referred to as a "Sapphic stanza" or "Sapphic verse." In Polish poetry, the Sapphic stanza has been adopted and adapted by various poets, allowing for artistic expression while maintaining the essence of the meter.
Audio compression refers to the process of reducing the size of an audio file while attempting to maintain its quality as much as possible. This is achieved by eliminating redundant or unnecessary data. There are two main types of audio compression: 1. **Lossy Compression**: This method reduces the file size by removing some audio data that is considered less important or less perceivable to the human ear. Examples of lossy compression formats include MP3, AAC, and OGG Vorbis.
"Order complete" typically refers to the status of a transaction or purchase in which all aspects of the order have been fulfilled. This means that the customer has successfully placed an order, the payment has been processed, and the items have been shipped or delivered. This status is commonly used in e-commerce and retail settings to indicate that there are no outstanding issues with the order and that the customer can expect their items as agreed.
Data compression software refers to programs designed to reduce the size of files and data sets by employing various algorithms and techniques. The primary goal of data compression is to save disk space, reduce transmission times over networks, and optimize storage requirements. This software works by identifying and eliminating redundancies within the data, thus allowing more efficient storage or faster transmission. There are two main types of data compression: 1. **Lossless Compression**: This method allows the original data to be perfectly reconstructed from the compressed data.
ARJ is a file archiving format and a software utility for compression and archiving data. Its name is derived from the initials of its creator, Rajesh F. Jain. The ARJ format was first introduced in the early 1990s and was mostly used in DOS environments. ARJ stands out for several features: 1. **Compression**: It uses sophisticated compression algorithms that often result in smaller archive sizes compared to some other formats available at the time.
Algebraic Code-Excited Linear Prediction (ACELP) is a speech coding algorithm used for compressing voice signals, primarily in telecommunications. It is a popular technique for encoding speech in a way that retains quality while reducing the amount of data needed for transmission. ### Key Features of ACELP: 1. **Linear Prediction**: ACELP relies on linear predictive coding (LPC), where the speech signal is modeled as a linear combination of its past samples.
Elias delta coding is a variable-length prefix coding scheme used for encoding integers, particularly useful in applications such as data compression and efficient numeral representation. It is part of a family of Elias codes, which also includes Elias gamma and Elias omega coding. The Elias delta coding scheme consists of the following steps for encoding a positive integer \( n \): 1. **Binary Representation**: First, determine the binary representation of the integer \( n \).
Entropy coding is a type of lossless data compression technique that encodes data based on the statistical frequency of symbols. It uses the principle of entropy from information theory, which quantifies the amount of unpredictability or information content in a set of data. The goal of entropy coding is to represent data in a more efficient way, reducing the overall size of the data without losing any information.
Golomb coding is a form of entropy encoding used in data compression, particularly suitable for representing non-negative integers with a geometric probability distribution. It was introduced by Solomon W. Golomb. The primary idea behind Golomb coding is to efficiently encode integers that commonly occur in certain applications, such as run-length encoding or certain types of image compression.
