Biodemographic studies are important for understanding the driving forces of the current longevity revolution (dramatic increase in huma... |
https://en.wikipedia.org/wiki/Modulus%20of%20smoothness | In mathematics, moduli of smoothness are used to quantitatively measure smoothness of functions. Moduli of smoothness generalise modulus of continuity and are used in approximation theory and numerical analysis to estimate errors of approximation by polynomials and splines.
Moduli of smoothness
The modulus of smoothn... |
https://en.wikipedia.org/wiki/Implementation%20theory | Implementation theory is an area of research in game theory concerned with whether a class of mechanisms (or institutions) can be designed whose equilibrium outcomes implement a given set of normative goals or welfare criteria.
There are two general types of implementation problems: the economic problem of producing a... |
https://en.wikipedia.org/wiki/List%20of%20circle%20topics | This list of circle topics includes things related to the geometric shape, either abstractly, as in idealizations studied by geometers, or concretely in physical space. It does not include metaphors like "inner circle" or "circular reasoning" in which the word does not refer literally to the geometric shape.

https://en.wikipedia.org/wiki/Overpopulation | Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosy... |
https://en.wikipedia.org/wiki/Rodrigues%20parrot | The Rodrigues parrot or Leguat's parrot (Necropsittacus rodricanus) is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is clas... |
https://en.wikipedia.org/wiki/Pattern%20search%20%28optimization%29 | Pattern search (also known as direct search, derivative-free search, or black-box search) is a family of numerical optimization methods that does not require a gradient. As a result, it can be used on functions that are not continuous or differentiable. One such pattern search method is "convergence" (see below), which... |
https://en.wikipedia.org/wiki/Conservation%20behavior | Conservation behavior is the interdisciplinary field about how animal behavior can assist in the conservation of biodiversity. It encompasses proximate and ultimate causes of behavior and incorporates disciplines including genetics, physiology, behavioral ecology, and evolution.
Introduction
Conservation behavior is a... |
https://en.wikipedia.org/wiki/Winding%20machine | A winding machine or winder is a machine for wrapping string, twine, cord, thread, yarn, rope, wire, ribbon, tape, etc. onto a spool, bobbin, reel, etc.
In textiles
Winders are used heavily in textile manufacturing, especially in preparation to weaving where the yarn is wound onto a bobbin and then used in a shuttle.... |
https://en.wikipedia.org/wiki/Physics%20Essays | Physics Essays is a quarterly journal supposedly covering theoretical and experimental physics. It was established in 1988 and the editor-in-chief is Emilio Panarella.
The journal has a reputation for being a "free forum where extravagant views on physics (in particular, those involving parapsychology) are welcome". ... |
https://en.wikipedia.org/wiki/Frequency%20changer | A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current (AC) of one frequency to alternating current of another frequency. The device may also change the voltage, but if it does, that is incidental to its principal purpose, since voltage conversion of al... |
https://en.wikipedia.org/wiki/NAP1L1 | Nucleosome assembly protein 1-like 1 is a protein that in humans is encoded by the NAP1L1 gene.
This gene encodes a member of the nucleosome assembly protein (NAP) family. This protein participates in DNA replication and may play a role in modulating chromatin formation and contribute to the regulation of cell prolife... |
https://en.wikipedia.org/wiki/Grid%20%28spatial%20index%29 | In the context of a spatial index, a grid or mesh is a regular tessellation of a manifold or 2-D surface that divides it into a series of contiguous cells, which can then be assigned unique identifiers and used for spatial indexing purposes. A wide variety of such grids have been proposed or are currently in use, inclu... |
