2012 VP113 is a trans-Neptunian object (TNO) that was discovered in November 2012. It is classified as a candidate for a part of the scattered disk, a distant region of the Solar System populated by icy bodies. 2012 VP113 is of particular interest because its orbit suggests that it might be influenced by the gravitational pull of a massive, yet unseen object in the outer Solar System, often referred to as "Planet Nine.
Lyon – Mont Verdun Air Base (French: Base aérienne de Lyon – Mont Verdun) is a military air base located in France, specifically situated near the town of Mont Verdun in the Auvergne-Rhône-Alpes region, approximately 15 kilometers from the city of Lyon. The base has served various roles and functions over the years, primarily associated with the French Air Force (Armée de l'Air).
Prophylactic cranial irradiation (PCI) is a preventive radiation therapy used primarily in patients with certain types of cancer, particularly small cell lung cancer (SCLC) and, in some cases, hematologic malignancies such as lymphoma and leukemia. The goal of PCI is to reduce the risk of the cancer spreading to the brain, which can occur in these types of cancers.
The metaplectic group is a significant concept in the fields of mathematics, particularly in representation theory and the theory of symplectic geometry. It is a double cover of the symplectic group, which means that it serves as a sort of "two-fold" representation of the symplectic group, capturing additional structure that cannot be represented by the symplectic group alone.
The 2010s was a transformative decade for the video game industry, marked by significant advancements in technology, game design, and distribution methods. Here are some key trends and developments from that period: 1. **Rise of Indie Games**: The 2010s saw a surge in independent game development. Platforms like Steam, consoles' digital storefronts, and tools such as Unity and Unreal Engine democratized game development.
The 2006 European cold wave refers to a significant cold weather event that impacted large parts of Europe during the winter of 2005-2006, particularly in January and February of 2006. This cold wave was characterized by exceptionally low temperatures, heavy snowfall, and severe winter conditions across many countries.
A **block cipher** is a type of symmetric encryption algorithm that processes data in fixed-size blocks (usually 64, 128, or 256 bits) of plaintext, transforming them into blocks of ciphertext of the same size. This method allows for secure data encryption by employing a secret key for both encryption and decryption operations. ### Key Features of Block Ciphers: 1. **Fixed Block Size**: Data is divided into blocks of a specific size.
The Bricklayer function, often denoted as \( b(n) \), is a mathematical concept associated with combinatorial enumeration, particularly in the context of tiling and covering problems. The function counts the number of ways to tile a linear strip (or row) of length \( n \) using specific types of tiles.
Indian plasma physicists are scientists and researchers from India who specialize in the study of plasma physics, which is the branch of physics that deals with ionized gases known as plasmas. Plasma is one of the four fundamental states of matter, alongside solid, liquid, and gas, and it consists of highly energized, charged particles.
The Schottky problem, often referred to in the context of number theory and algebraic geometry, is named after the mathematician Friedrich Schottky. It addresses questions related to the representation of certain algebraic structures, particularly in connection with the theory of abelian varieties and modular forms. In more specific terms, the Schottky problem can be framed as follows: it concerns the characterization of Jacobians of algebraic curves.
A commitment scheme is a cryptographic construct that allows one party, known as the "committer," to commit to a chosen value while keeping it hidden from another party, known as the "receiver." The committer can later reveal the committed value, at which point the receiver can verify that the value corresponds to the original commitment. The main features of a commitment scheme are: 1. **Hiding:** The committed value is hidden from the receiver until the committer chooses to reveal it.
The 29th meridian west is a line of longitude that is 29 degrees west of the Prime Meridian, which is located at 0 degrees longitude. This meridian runs from the North Pole to the South Pole, passing through various countries in its path. In particular, the 29th meridian west crosses parts of the following regions: - **Greenland**: It passes through the eastern part of this large island.
John Trowbridge was an American physicist known for his work in experimental physics. He contributed significantly to various fields, including optics and photonics. Trowbridge was also known for his research in the area of laser technology and material science.
Radiation-induced lung injury (RILI) refers to the damage that occurs to lung tissue as a result of exposure to radiation, typically from therapeutic radiation used in the treatment of cancers located in or near the thoracic region, such as lung cancer, breast cancer, and esophageal cancer. RILI can occur as a result of radiation therapy delivering high doses of radiation to the lungs, leading to inflammation and injury. **Types of RILI:** 1.
The number 202 is an integer that comes after 201 and before 203. In terms of its properties: - It is an even number. - It is a composite number, meaning it has divisors other than 1 and itself (the divisors of 202 are 1, 2, 101, and 202). - In Roman numerals, 202 is represented as CCII. - In binary, it is written as 11001010.
Lawrence H. Johnston is a notable figure recognized for his accomplishments in the field of engineering and technology, particularly as a pioneer in the development of advanced electronic systems. However, the context regarding his work and contributions can vary widely, as there may be multiple individuals named Lawrence H. Johnston in different fields. If you are referring to a specific Lawrence H.
The 2018 Shanghai knife attack refers to a violent incident that occurred on March 21, 2018, when a man wielding a knife attacked passengers at the Shanghai Nanpu Bridge subway station in Shanghai, China. The attacker injured multiple people before being subdued by police. The incident raised concerns about public safety and security, particularly in crowded urban areas. Authorities responded swiftly to ensure the safety of the public, and the attacker was apprehended.
"Reactions on surfaces" typically refers to the processes that occur on the surfaces of solid materials, especially in the context of catalysis, materials science, and surface chemistry. These reactions are important in various fields, including environmental science, energy production, and industrial catalysis.
