Laser ablation synthesis in solution (LASS) is a technique used to create nanoparticles or nanostructured materials by using focused laser beams to ablate a solid target material while immersed in a liquid medium. This technique combines principles from laser ablation and chemical synthesis within a solvent, leading to the formation of nanoparticles with specific sizes, shapes, and properties.
Polish organ tablatures refer to a system of musical notation used for writing music for the organ in Poland, particularly during the Renaissance and Baroque periods. Unlike standard notation, which uses a staff and note heads to indicate pitch and rhythm, tablature employs a more visual approach, often indicating which keys to press and where the fingers should be placed.
The term "6 µm process" refers to a semiconductor manufacturing technology that has a minimum feature size of 6 micrometers (µm) which is equivalent to 6,000 nanometers. This process is part of a family of technologies used to fabricate integrated circuits (ICs), where the size of the features on the chip (such as transistors, resistors, and capacitors) measures 6 µm or larger.
Nanostructures are materials or objects with dimensions in the nanometer range, typically between 1 and 100 nanometers (1 nanometer is one billionth of a meter). At this scale, the physical and chemical properties of materials can differ significantly from those of the same materials in bulk form due to a high surface-area-to-volume ratio and quantum effects.

The Cambridge Ring is a pioneering computer networking architecture developed in the 1970s at the University of Cambridge in the UK. It was designed as a local area network (LAN) based on a token ring topology, allowing multiple computers to communicate with each other in a controlled manner. Key features of the Cambridge Ring include: 1. **Token Ring Protocol**: The network uses a token-passing mechanism, where a special packet, or "token," circulates around the ring structure.
Metro Ethernet is a high-speed networking technology that uses Ethernet protocols to connect users to their local area networks (LANs) and to metropolitan area networks (MANs) over a wide area. It is designed to provide reliable, high-bandwidth communication services in urban settings. Here are some key characteristics of Metro Ethernet: 1. **Architecture**: Metro Ethernet typically employs a point-to-multipoint topology.
In music, "note value" refers to the duration or length of time a note is held relative to other notes in a piece of music. It indicates how long a note should be played or sung. Different note values correspond to different time durations and are typically notated in sheet music. Common note values include: 1. **Whole Note** (Semibreve) - Typically held for four beats. 2. **Half Note** (Minim) - Typically held for two beats.
The NYIT Bears are the athletic teams representing the New York Institute of Technology (NYIT), which is located in Old Westbury, New York. The Bears participate in various sports and compete at the NCAA Division II level. The athletic program encompasses a range of men's and women's sports, including basketball, soccer, volleyball, and more.
A hypertree network is a type of data structure used in computer science, particularly in the fields of databases, graph theory, and distributed systems. The concept is often associated with the representation and manipulation of complex relationships within datasets that exhibit a hypergraph structure. Here are some key points regarding hypertree networks: 1. **Hypergraphs**: Unlike traditional graphs where edges connect two vertices, hypergraphs allow edges (called hyperedges) to connect any number of vertices.
NUTS, or the Nomenclature of Territorial Units for Statistics, is a hierarchical classification system used by the European Union for statistical purposes. In Norway, the NUTS classification is applied to regions for statistical analysis and reporting. As of the latest classifications, Norway is divided into NUTS-1, NUTS-2, and NUTS-3 regions: 1. **NUTS-1:** This is the highest level and includes larger regions of the country.
"Ring protection" typically refers to a security feature or design philosophy used in computer operating systems and hardware architectures to enforce access control and isolate different levels of execution for programs. This concept is most commonly associated with the architecture of the x86 microprocessor, but it can also apply to other systems.

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.
