Smearing retransformation is a statistical method often used in the context of regression analysis, particularly when dealing with models that involve transformation of the dependent variable. The method addresses the issue of bias that can arise when transforming data, especially when the outcome is log-transformed or otherwise modified to meet model assumptions.

Nuclear weapons delivery refers to the methods and systems used to transport and deploy nuclear weapons to their intended targets. The effectiveness of a nuclear weapon is not only dependent on the weapon itself but also largely on how it is delivered. Various delivery systems are designed to ensure that nuclear warheads can reach their targets accurately and efficiently while surviving any potential countermeasures.

An oblique lattice refers to a specific type of two-dimensional lattice structure in crystallography and solid-state physics. In geometry, a lattice is a regular arrangement of points in space, and in the context of crystallography, it often describes the arrangement of atoms in a crystal. An oblique lattice is characterized by two non-orthogonal basis vectors that define a parallelogram in a two-dimensional space.

An Ocean Data Acquisition System (ODAS) refers to a set of tools and technologies used to collect, process, and store various types of data related to the ocean and marine environments. These systems are integral to marine research, environmental monitoring, and various commercial applications, such as fishing, shipping, and oil and gas exploration.

Octahedral molecular geometry is a three-dimensional shape that occurs when a central atom is surrounded symmetrically by six other atoms or groups of atoms (ligands). In this arrangement, the central atom is positioned at the center of an octahedron, and the six surrounding atoms occupy the corners of this geometric shape. Key characteristics of octahedral molecular geometry include: 1. **Bond Angles**: The bond angles between the atom pairs are all 90 degrees, providing a symmetrical arrangement.

Octavius Wigram is primarily known as a historical figure associated with the British naval and marine industries in the 19th century. He was particularly noted for his involvement in shipbuilding and his contributions to the design of naval vessels. His legacy includes influence on maritime engineering and advancements in naval architecture during that era.

The Odesa Nuclear Power Plant, sometimes referred to with its designation as the "Odesa NPP," is a proposed nuclear power plant that is aimed at being constructed near the city of Odesa, Ukraine. However, as of my last knowledge update in October 2023, the plant had not been completed or brought into operation.

Ojin Seamount is an underwater volcanic structure located in the northwest Pacific Ocean, specifically northeast of the main islands of Japan, near the Ogasawara Islands (Bonin Islands). It is part of the Izu-Bonin-Mariana Arc, which is a volcanic arc system created by the subduction of the Pacific Plate beneath the North American Plate. Ojin Seamount is notable for its geological features, which include a broad, flat summit, steep slopes, and volcanic formations.

Olivier Guéant is a French politician and a member of the political party The Republicans (Les Républicains). He is known for his various roles within the French government, including serving as the Secretary of State for Internal Security under President Nicolas Sarkozy. Throughout his career, Guéant has been involved in law enforcement and public administration.

Olga Cavalli is an Argentine politician and diplomat known for her work in various international and governmental roles. She has been involved in issues related to technology, communications, and digital governance. Cavalli has represented Argentina in international forums and has expertise in the fields of telecommunications and information technology. Apart from her political work, she has played a significant role in the Internet Governance Forum (IGF) and has been active in promoting digital inclusion and accessibility.

In molecular biology, a primer is a short single-stranded nucleic acid (RNA or DNA) that serves as a starting point for DNA synthesis. Primers are essential for various molecular techniques, including polymerase chain reaction (PCR), DNA sequencing, and cloning. Here are some key points about primers: 1. **Structure**: Primers are typically 18-30 nucleotides long and are complementary to the target DNA sequence.

Open interest in the context of futures trading refers to the total number of outstanding contracts that are held by market participants at the end of a trading day. It represents the number of contracts that have been initiated but not yet liquidated, either by offsetting trades or by physical delivery. Here are some key points about open interest: 1. **Measure of Market Activity**: Open interest provides insights into the level of activity and liquidity in a particular futures market.

An Operational-Level Agreement (OLA) is a formal document that outlines the responsibilities and expectations between different internal teams or departments within an organization. It serves to clarify the services, processes, and performance metrics that will be adhered to by the involved parties to ensure smooth operations and effective service delivery. Key features of an OLA include: 1. **Scope of Services**: It specifies the services provided by each team, detailing what is included and what is excluded.

Operator K-theory is a branch of mathematics that studies certain algebraic structures (specifically, K-theory) related to the space of bounded linear operators on Hilbert spaces, often in the context of noncommutative geometry and functional analysis. It generalizes classical topological K-theory to a noncommutative setting, particularly useful in the study of C*-algebras and von Neumann algebras.

Optical force refers to the force exerted on particles, objects, or materials due to the momentum transfer from light (or electromagnetic radiation). This phenomenon can be observed in various contexts, including optical trapping, radiation pressure, and the interaction of light with matter. ### Key Concepts: 1. **Radiation Pressure**: When light hits a surface, it transfers momentum to that surface, leading to a force.

The Ordered Weighted Averaging (OWA) aggregation operator is a mathematical tool used in decision-making and aggregation tasks, particularly in scenarios where decision criteria are uncertain, and risk attitudes need to be accounted for. The OWA operator was introduced by Ronald R. Yager in the late 1980s as part of the field of fuzzy set theory and based on the concept of ordered structures in data.

The geoduck, a large species of clam native to the Pacific Northwest of North America, belongs to the order **Veneroida**. The scientific name for the geoduck is **Panopea generosa**. This order is part of the class Bivalvia, which encompasses various types of clams, oysters, and mussels. Geoducks are known for their long siphons and their burrowing habitat in marine environments.

Orosomucoid, also known as alpha-1-acid glycoprotein (AGP), is a glycoprotein that is predominantly produced by the liver. It is classified as an acute-phase protein, meaning its levels can increase significantly in response to inflammation, infection, and other stressors.

Orthogonal diagonalization is a process in linear algebra that involves transforming a symmetric matrix into a diagonal form through an orthogonal change of basis.

Oskar Anderson refers to a couple of different concepts. One notable instance is Oskar Anderson (1876–1960), a Swedish mathematician known for his work in the realm of functional analysis, topology, and related fields. He also contributed to the field of summability theory. In addition to being a mathematician, "Oskar Anderson" might refer to various other individuals or entities depending on the context, including fictional characters or organizations.
