J-Anomaly Ridge is an underwater geological feature located in the central Atlantic Ocean. It is characterized by a significant positive geoid anomaly that is thought to result from a combination of geological factors, including variations in crustal thickness, mantle dynamics, and volcanic activity. The ridge is part of a broader system of underwater features that reflect the geological processes that shape the ocean floor, including seafloor spreading, tectonic activity, and sedimentation.

János Pach is a prominent Hungarian mathematician known for his contributions to combinatorial geometry, discrete geometry, and related areas. Born on April 21, 1946, he has worked extensively in fields such as convex geometry, incidence geometry, and graph theory. Pach has authored numerous research papers and co-authored books, making significant impacts through both theoretical work and practical applications in mathematics.

Japanese women mathematicians have made significant contributions to various fields of mathematics. Although historically, the representation of women in mathematics, like in many scientific fields, has been limited, there are notable figures who have excelled and paved the way for future generations. Some prominent Japanese women mathematicians include: 1. **Kunihiko Kodaira** - While not a woman, it's important to mention that Kodaira's work has influenced Japanese women mathematicians.

Java Modeling Language (JML) is formal specification language used to describe the behavior of Java modules (classes and interfaces) in a way that is understandable to both humans and computers. JML is an extension of the Java programming language, designed to specify what a program is supposed to do rather than how it does it.

Jay M. Gould, commonly known as Stephen Jay Gould, was an American paleontologist, evolutionary biologist, and science writer. He was born on September 10, 1941, and passed away on May 20, 2002. Gould was known for his contributions to the field of evolutionary biology, particularly the concept of punctuated equilibrium, which he developed with Niles Eldredge.

Jean Du Breuil was a French writer and philosopher, known for his works in the early modern period. One of his notable contributions is in the field of mathematics and geometry, particularly through his treatises that discuss the principles of geometry and their applications. He is also recognized for his thoughts on the nature of knowledge, science, and the philosophy of education.

Jeanne Ferrante is a computer scientist known for her work in the field of computer science, particularly in algorithms, computational geometry, and parallel computing. She has contributed to the education and research in these areas, including the development of algorithms for various computational problems. Additionally, she has been recognized for her efforts in promoting diversity and inclusion within the field of computer science.

Jean Pedersen can refer to different individuals or subjects, but without more specific context, it's hard to pinpoint exactly what you're asking about. If you are referring to a specific person, it would help to provide additional details, such as their occupation or significance.

Jean Zinn-Justin is a French theoretical physicist known for his contributions to statistical physics, quantum field theory, and the study of phase transitions. He has been particularly recognized for his work on the renormalization group and its applications in statistical mechanics and condensed matter physics. Zinn-Justin is also known for his publications, including textbooks that aim to educate students and researchers about advanced topics in these fields.

Jie Tang is an academic known for his work in the fields of computer science, particularly in data mining, social network analysis, and machine learning. He has published numerous papers and contributed to advancements in understanding and processing large-scale data, as well as developing algorithms for analyzing social networks and complex systems.

The J-integral is a contour integral used in fracture mechanics to characterize the intensity of the stress and strain field near the tip of a crack. It serves as a measure of the energy release rate when a crack propagates in a material, providing insights into the material's fracture toughness and resistance to crack growth.

A Rankine body is a theoretical concept used in fluid mechanics, particularly in the study of flow past bodies. It represents a simplified model of a body where the flow around it is analyzed using potential flow theory. The body is usually assumed to have a specific shape—often a flat plate or a cylindrical shape—where the flow is considered inviscid (non-viscous) and incompressible.

Johari–Goldstein relaxation refers to a concept in the field of statistical mechanics and thermodynamics, particularly in the study of glassy systems. It is named after two researchers, Joseph Johari and Steven Goldstein, who introduced the idea in their work on the dynamics of glasses. In general, relaxation processes in materials can occur when a system approaches equilibrium after a disturbance.

John Dewey was a prominent American philosopher, psychologist, and educational reformer associated with pragmatism and functional psychology. His work spans numerous disciplines, including philosophy, education, and social theory. Below is a selection of significant works by Dewey, though this is not an exhaustive bibliography: ### Books 1. **Psychology** (1887) - An important early work that sought to integrate psychology with philosophy.

John McKay is a notable mathematician known for his contributions to various areas of mathematics, particularly in number theory, representation theory, and the theory of finite groups. He is perhaps best known for his work on the Conway group and for the McKay correspondence, which explores a deep connection between finite subgroup representations of certain Lie algebras and the geometry of algebraic surfaces. McKay's correspondence highlights a relationship between the representations of finite groups and the structure of algebraic varieties.

John Robert Mills could refer to various entities or individuals, but without additional context, it's unclear who or what you are specifically asking about. It could be a reference to a person with that name—potentially a private individual or a professional in a certain field—or it might refer to a fictional character, a unique concept, or a specific location or institution.

John Sallis is an American philosopher known for his work in phenomenology, existentialism, aesthetics, and the philosophy of art. He has written extensively on a range of topics, including the relationship between art and philosophy, the nature of perception, and the significance of place and environment in human experience. His work often draws on figures such as Martin Heidegger and Edmund Husserl, blending insights from continental philosophy with discussions of visual art, architecture, and poetry.

John Scott Russell (1808–1882) was a Scottish civil engineer and a prominent figure in the field of hydraulics and naval engineering. He is best known for his work on wave motion and for discovering what is now known as the "Russell wave," or "solitary wave." This phenomenon occurs when a wave travels over a medium without changing shape, often observed in shallow water.

In the context of \( C^* \)-algebras, the **real rank** is a notion that captures information about the structure of the algebra, specifically its ideal structure and the behavior of self-adjoint elements.

The Czech Republic, officially known as Czechia, is divided into several administrative regions, each with its own unique cultural and geographical characteristics. As of my last update in October 2023, there are 13 standard administrative regions and one city that has a special status. Here is a list of the regions: 1. **Central Bohemia Region (Středočeský kraj)** – Surrounds the capital city of Prague and is known for its historical towns and landscapes.
