Hemodynamics is the study of the movement of blood within the circulatory system and the forces that govern this movement. It encompasses the principles of fluid dynamics as they apply to blood flow, pressure, and resistance within the blood vessels. Hemodynamics is critical for understanding the function of the cardiovascular system and is crucial in clinical settings, especially in assessing and managing conditions like hypertension, heart failure, and other cardiovascular disorders.
"The Library of Babel" is a short story written by Argentine author Jorge Luis Borges, first published in 1941 in his collection "The Garden of Forking Paths." The story describes a fictional library that contains an infinite number of books, each consisting of all possible combinations of letters and characters. In this library, there exists a vast collection of texts that covers every possible permutation of a given set of symbols.
Ambulatory blood pressure monitoring (ABPM) is a method used to measure blood pressure at regular intervals over a 24-hour period while a person goes about their normal daily activities. This technique involves wearing a portable blood pressure monitor, typically on the arm, which automatically takes blood pressure readings every 15 to 30 minutes throughout the day and every 30 to 60 minutes at night.
The Frank–Starling law, also known as the Frank–Starling mechanism or the Starling law of the heart, describes the relationship between the stretch of cardiac muscle fibers and the force of contraction. It states that the greater the volume of blood entering the heart during diastole (the filling phase), the greater the force of contraction during systole (the pumping phase). In simpler terms, the more the heart muscle is stretched by incoming blood, the more forcefully it contracts.
Amplitude-integrated electroencephalography (aEEG) is a simplified form of continuous brain function monitoring used primarily in neonatology. It provides a way to assess and display brain activity in infants, especially those who are premature or critically ill, in a more accessible and interpretable manner than traditional electroencephalography (EEG).
Biological half-life is the time required for the concentration of a substance (such as a drug, toxin, or radioactive material) in a biological system to reduce to half its initial amount due to biological processes. This concept is crucial in pharmacology, toxicology, and other fields involving the study of substances within living organisms. The biological half-life can be influenced by various factors, including: 1. **Metabolism**: The rate at which the body chemically alters the substance.
Design of Experiments (DOE) is a systematic method used in statistics for planning, conducting, analyzing, and interpreting controlled tests to evaluate the factors that may influence a particular outcome or response. It is commonly applied in various fields, including agriculture, engineering, pharmaceuticals, and social sciences, to understand the relationships between different inputs (factors) and outputs (responses).
In pharmacology, "effective dose" (often denoted as ED) refers to the dose of a drug or therapeutic agent that produces a desired or therapeutic effect in a specified percentage of the population or in a specific clinical context. It is a critical concept in understanding the relationship between drug dosage and therapeutic efficacy. The most commonly cited metric is the ED50, which is the dose at which 50% of the population exhibits a specified effect.
The Starling equation describes the forces that govern the movement of fluid across capillary membranes in the body. Specifically, it relates to the balance of hydrostatic pressure and oncotic pressure that influences the filtration and absorption of fluids in the capillaries and surrounding tissues. The equation is essential in understanding fluid dynamics in the circulatory system and is often used in physiology and medicine to explain edema and fluid balance.
The Thrombodynamics test is a laboratory assay used to evaluate the dynamics of blood coagulation and the formation of blood clots in real-time. This test provides insights into the way blood coagulation occurs in a controlled environment, mimicking physiological conditions. It is particularly useful for assessing the functionality of various components involved in coagulation, such as platelets, coagulation factors, and the overall hemostatic process.
Op. 120, No. 1 is a piece composed by the Italian composer Luciano Berio, specifically his "Sequenza IX" for solo clarinet. The term “Op. 120, No. 1” may be a mislabeling, as Op. 120 generally refers to a set of works by Johannes Brahms, which includes two clarinet sonatas.
The American Mathematical Society (AMS) is a professional association based in the United States that publishes a number of prestigious academic journals in various fields of mathematics. These journals serve as platforms for researchers to publish their findings, share knowledge, and advance the field of mathematics. Some of the notable journals published by the AMS include: 1. **Transactions of the American Mathematical Society**: Contains research articles of broad interest and importance in all areas of mathematics.
In academic contexts, a "stub" refers to an article that is incomplete or lacks comprehensive information. Mathematics journal stubs would specifically denote articles related to mathematics that need further development. These stubs usually contain basic information but lack the depth, detail, and breadth necessary for a thorough understanding of the topic. For example, a stub might have minimal definitions, insufficient explanation of concepts, or fail to reference significant research or applications.
AStA Advances in Statistical Analysis is a scholarly journal that publishes research articles in the field of statistical science. It focuses on the development and application of statistical methods and their application in various domains, including economics, social sciences, health sciences, and more. The journal aims to encourage theoretical advancements in statistics as well as the use of innovative statistical techniques in practical applications.
"Advances in Group Theory and Applications" is likely a scholarly journal or publication focused on the field of group theory, which is a branch of mathematics that studies the algebraic structures known as groups. In general, such publications typically include research articles, reviews, and possibly conference proceedings that explore new findings, theoretical advancements, and applications of group theory in various areas of mathematics and related fields.

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
