The laminar sublayer is a thin region in fluid dynamics, specifically within the context of boundary layers that develop along surfaces in flow conditions. In turbulent flow near a solid boundary, the flow can be characterized by various layers: 1. **Viscous Sublayer**: This is the region closest to the wall, where the effects of viscosity are significant. Within this layer, the flow is often considered laminar, meaning that it is orderly and fluid particles move in parallel layers with minimal mixing.
In this malformed Coinbase transaction, the mining pool "nicehash" produced a provably unspendable Bitcoin output script due to a bug, and therefore lost most of the entire block reward of 6.25 BTC then worth about $ 123,000.
The output is unspendable because it ends in a constant 0, the disassembly of the first and main output is this series of constants:
0 017fed86bba5f31f955f8b316c7fb9bd45cb6cbc 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
and for the second smaller one:

the third one being an OP_RETURN message.
Language planning refers to the deliberate efforts to influence the function, structure, or acquisition of a language within a community or country. It is often undertaken by governments, educational institutions, or linguistic organizations to address issues related to language use, development, preservation, or promotion. Language planning can encompass various aspects, including: 1. **Status Planning**: This involves decisions about which languages will have official status, which will be used in government and education, and which may be promoted over others.
The Laplacian vector field typically refers to a vector field that is derived from the Laplacian operator. The Laplacian operator, denoted as \( \nabla^2 \) or \( \Delta \), is a second-order differential operator that acts on scalar or vector fields.
Larry A. Wasserman is a prominent statistician and professor known for his contributions to statistical theory and methodology. He has been involved in various research areas, including statistical learning, Bayesian statistics, and machine learning. Wasserman has authored several influential books and papers in statistics and has been affiliated with institutions such as Carnegie Mellon University. He is also recognized for his work in developing statistical methods in the context of complex data and applications in fields such as genetics and social sciences.
"Laser & Photonics Reviews" is a scientific journal that focuses on research in the fields of lasers and photonics. The journal publishes high-quality reviews, original research articles, and special issues covering various aspects of photonics, including the generation, manipulation, and application of light. Topics often include but are not limited to laser technology, optical materials, photonic devices, and applications in communications, sensing, and imaging.
As of my last knowledge update in October 2023, "Dark Ages Radio Explorer" doesn't refer to a widely recognized product, service, or concept. It could potentially be a niche or emerging project related to radio, history, or perhaps a creative work such as a podcast, music compilation, or an audio exploration of the historical period known as the Dark Ages.
Non-standard cosmology refers to alternative theories and models of the universe that deviate from the widely accepted ΛCDM model (Lambda Cold Dark Matter model). While the ΛCDM model successfully explains many observations in cosmology, such as the cosmic microwave background radiation, large-scale structure, and the expansion of the universe, non-standard cosmological theories propose different mechanisms, components, or interpretations to explain these phenomena.
Physical properties are characteristics of a substance that can be observed or measured without changing the substance's chemical composition. These properties help in identifying and describing materials. Some common physical properties include: 1. **Color**: The color of the material. 2. **Odor**: The smell associated with the substance. 3. **Density**: The mass per unit volume of a substance, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
Electrical systems refer to the organized arrangement of components that generate, transmit, distribute, and utilize electrical energy. They encompass a wide array of elements such as power generation sources, transformers, transmission lines, distribution networks, and end-use devices. Here are some core components and concepts related to electrical systems: 1. **Generation**: This is the initial stage where electrical energy is produced.
In circuit theory, a generator is an active electrical device that converts one form of energy into electrical energy. Generators can provide electrical power in various forms, typically through a mechanical process, chemical reaction, or other means of energy conversion. The term "generator" is commonly used to refer to several types of devices, including: 1. **AC Generators (Alternators)**: These convert mechanical energy into alternating current (AC) electrical energy.
Resins are complex organic compounds that are typically produced by trees, plants, and some insects. They are usually viscous liquids or semi-solid substances that can harden upon exposure to air or heat. Resins are often classified into two main categories: 1. **Natural Resins**: These are produced by plants and trees as a protective mechanism against injury or disease.

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
