Vyacheslav Feodoritov is not a widely recognized figure in mainstream media or academic literature as of my last update in October 2023. If you're referring to a specific individual, it’s possible that he may be known in a particular niche, field, or region. Without additional context, it's difficult to provide accurate information.
Yakov Pesin is a prominent Russian-American mathematician known for his contributions to the field of dynamical systems, particularly in the theory of chaotic systems and ergodic theory. He is recognized for his work on the structure of invariant measures and the concept of the "Pesin theory" related to the behavior of dynamical systems that exhibit chaotic behavior.
Yury Yershov is a name that might refer to different individuals, but without additional context, it is challenging to provide a specific answer.
As of my last knowledge update in October 2021, "Passeree" does not refer to any widely recognized term, concept, business, or product. It is possible that it may refer to something that emerged after that date or is relatively niche.
The unit of electrical conductance is the siemens (S). It is defined as the reciprocal of electrical resistance, which is measured in ohms (Ω). Therefore, 1 siemens is equivalent to 1/ohm or \( S = \frac{1}{\Omega} \). Additionally, in other contexts, conductance can also be expressed in terms of mhos (℧), which is simply ohms spelled backward, although this terminology is less commonly used today.
NeuroSky is a company that specializes in the development of brainwave monitoring technology and applications. Founded in 2004, NeuroSky focuses on creating consumer and medical devices that utilize electroencephalography (EEG) to measure brain activity. Their technology often involves the use of lightweight and affordable headsets or sensors that can detect brainwave patterns and convert them into data that can be used for various applications, such as gaming, meditation, and cognitive training.
The Maurer–Cartan form is a fundamental concept in the theory of Lie groups and differential geometry, particularly in the study of Lie group representations and the geometry of principal bundles. Given a Lie group \( G \), the Maurer–Cartan form is a differential 1-form on the Lie group that captures information about the group structure in terms of its tangent space.
A "moving frame" can refer to different concepts depending on the context, including mathematics, physics, and engineering. Here are a few interpretations: 1. **Mathematics (Differential Geometry)**: In the context of differential geometry, a moving frame is often used to describe a set of vectors that vary along a curve or surface.
In music, a "key" refers to the tonal center around which a piece of music is organized. It is defined by a specific scale that serves as the foundation for melodies and harmonies within a composition. Each key is typically associated with a specific note (the tonic) and a set of pitches that can be used in the music. Keys are categorized as major or minor: 1. **Major Key**: Associated with a bright and happy sound.
In v4.2, look under arch/x86/:
  • include/asm/pgtable*
  • include/asm/page*
  • mm/pgtable*
  • mm/page*
There seems to be no structs defined to represent the pages, only macros: include/asm/page_types.h is specially interesting. Excerpt:
#define _PAGE_BIT_PRESENT   0   /* is present */
#define _PAGE_BIT_RW        1   /* writeable */
#define _PAGE_BIT_USER      2   /* userspace addressable */
#define _PAGE_BIT_PWT       3   /* page write through */
arch/x86/include/uapi/asm/processor-flags.h defines CR0, and in particular the PG bit position:
#define X86_CR0_PG_BIT      31 /* Paging */

The first thing you must understand is the Classic RISC pipeline with a concrete example.
Natural pseudodistance is a concept used in mathematical biology and ecology, particularly in the study of population genetics and evolutionary theory. It is typically used to quantify the genetic differences or relationships between populations or individuals based on genetic data. In general, a pseudodistance is a metric that measures how "far apart" two entities are within a particular space or context, but it may not fulfill all the properties of a true distance metric (such as the triangle inequality).

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
