https://en.wikipedia.org/wiki/Hansen%E2%80%93Jagannathan%20bound | Hansen–Jagannathan bound is a theorem in financial economics that says that the ratio of the standard deviation of a stochastic discount factor to its mean exceeds the Sharpe ratio attained by any portfolio. This result applies, among others, the Cauchy–Schwarz inequality. The Hansen-Jagannathan (H-J) bound is a type ... |
https://en.wikipedia.org/wiki/Indiscernibles | In mathematical logic, indiscernibles are objects that cannot be distinguished by any property or relation defined by a formula. Usually only first-order formulas are considered.
Examples
If a, b, and c are distinct and {a, b, c} is a set of indiscernibles, then, for example, for each binary formula , we must have

https://en.wikipedia.org/wiki/Photuris%20%28protocol%29 | In computer networking, Photuris is a session key management protocol defined in RFC 2522.
Photuris is the Latin name of a genus of fireflies native to North America that mimic the signals of other firefly species. The name was chosen as a reference to the (classified) FIREFLY key exchange protocol developed by the Na... |
https://en.wikipedia.org/wiki/BigDog | BigDog is a dynamically stable quadruped military robot that was created in 2005 by Boston Dynamics with Foster-Miller, the NASA Jet Propulsion Laboratory, and the Harvard University Concord Field Station. It was funded by DARPA, but the project was shelved after the BigDog was deemed too loud for combat.

https://en.wikipedia.org/wiki/J%E2%80%93Machine | The J–Machine (Jellybean-Machine) was a parallel computer designed by the MIT Concurrent VLSI Architecture group in conjunction with the Intel Corporation. The machine used "jellybean" parts—cheap and multitudinous commodity parts, each with a processor, memory, and a fast communication interface—and a novel network in... |
https://en.wikipedia.org/wiki/Imbibition | Imbibition is a special type of diffusion that takes place when liquid is absorbed by solids-colloids causing an increase in volume. Water surface potential movement takes place along a concentration gradient; some dry materials absorb water. A gradient between the absorbent and the liquid is essential for imbibition. ... |
https://en.wikipedia.org/wiki/Manipulability%20ellipsoid | In robotics, the manipulability ellipsoid is the geometric interpretation of the scaled eigenvectors resulting from the singular value decomposition of the jacobian that describes a robot's motion. |
https://en.wikipedia.org/wiki/Spherical%20cow | The spherical cow is a humorous metaphor for highly simplified scientific models of complex phenomena. Originating in theoretical physics, the metaphor refers to physicists' tendency to reduce a problem to the simplest form imaginable in order to make calculations more feasible, even if the simplification hinders the m... |
https://en.wikipedia.org/wiki/Structural%20Equation%20Modeling%20%28journal%29 | Structural Equation Modeling is a peer-reviewed scientific journal publishing methodological and applied papers on structural equation modeling, a blend of multivariate statistical methods from factor analysis to systems of regression equations, with applications across a broad spectrum of social sciences as well as bi... |
https://en.wikipedia.org/wiki/Monotone%20matrix | A real square matrix is monotone (in the sense of Collatz) if for all real vectors , implies , where is the element-wise order on .
Properties
A monotone matrix is nonsingular.
Proof: Let be a monotone matrix and assume there exists with . Then, by monotonicity, and , and hence .
Let be a real square matrix... |
https://en.wikipedia.org/wiki/Surface%20reconstruction | Surface reconstruction refers to the process by which atoms at the surface of a crystal assume a different structure than that of the bulk. Surface reconstructions are important in that they help in the understanding of surface chemistry for various materials, especially in the case where another material is adsorbed o... |
https://en.wikipedia.org/wiki/TreeFam | TreeFam (Tree families database) is a database of phylogenetic trees of animal genes. It aims at developing a curated resource that gives reliable information about ortholog and paralog assignments, and evolutionary history of various gene families.
TreeFam defines a gene family as a group of genes that evolved after ... |
