Christophe Fraser is a researcher and academic known for his work in the field of infectious diseases, epidemiology, and public health. He has made significant contributions to the understanding of various infectious diseases, including HIV and tuberculosis, and has been involved in the development of mathematical models to predict disease spread and inform public health interventions.
AIDA (Artificial Intelligence Diabetes Assistant) is an interactive educational freeware diabetes simulator designed to help individuals—such as patients, healthcare professionals, and students—understand diabetes management. It typically allows users to simulate various scenarios related to diabetes treatment, such as managing blood glucose levels, understanding insulin dosages, and recognizing the impacts of food intake, physical activity, and other lifestyle factors on diabetes.
Risa Wechsler is an astrophysicist known for her work in cosmology, particularly in the areas of galaxy formation, large-scale structure, and dark energy. She has contributed to our understanding of the universe's evolution and the distribution of galaxies. Wechsler has been involved in various research projects and collaborations, including those focused on cosmic surveys and simulations to study the properties of dark matter and the expansion of the universe.
The Narrow Escape Problem is a concept often encountered in mathematical biology, particularly in the field of diffusion processes and stochastic processes. It refers to the study of how particles (or small organisms) escape from a confined space through a narrow opening or boundary. In more technical terms, it examines the diffusion of particles that are subject to certain conditions, such as being confined within a domain but having a small chance of escaping through a specific narrow region (e.g., an exit or an absorbing boundary).
"On Growth and Form" is a seminal work written by the British biologist D'Arcy Wentworth Thompson and first published in 1917. The book explores the relationship between biology and geometry, examining how the forms of living organisms are influenced by physical and mathematical principles. Thompson emphasizes that the shapes of organisms cannot be understood simply through evolutionary biology; instead, he argues that physical forces, mechanical properties, and mathematical patterns play a crucial role in shaping biological structures.
The Paradox of the Plankton refers to an ecological conundrum identified by G.E. Hutchinson in 1961 regarding the coexistence of a large number of planktonic algal species in aquatic ecosystems, particularly in the face of competition for limited resources. According to the competitive exclusion principle, two species competing for the same resources cannot coexist indefinitely; one species will typically outcompete the other.
A list of axioms is a collection of fundamental propositions or statements that are accepted as true without proof within a given mathematical or logical framework. Axioms serve as the foundational building blocks from which further theorems and propositions can be derived. Different fields, such as mathematics, physics, and philosophy, may have their own specific sets of axioms.
A Drosophila melanogaster has about 135k neurons, and we only managed to reconstruct its connectome in 2023.
The human brain has 86 billion neurons, about 1 million times more. Therefore, it is obvious that we are very very far away from a full connectome.
Instead however, we could look at larger scales of connectome, and then try from that to extract modules, and then reverse engineer things module by module.
This is likely how we are going to "understand how the human brain works".
Some notable connectomes:
The Encyclopedia of Triangle Centers is a comprehensive resource dedicated to the study of various notable points associated with triangles, known as triangle centers. These include well-known centers such as the centroid, orthocenter, circumcenter, and incenter, among many others. The encyclopedia aims to catalog these centers, providing their mathematical properties, relationships, formulas, and sometimes historical contexts. The work typically includes both theoretical aspects and practical applications, offering insights that could be beneficial for mathematicians, educators, and students.
Inspec is an open-source testing framework primarily used for infrastructure as code (IaC) compliance and security auditing. Developed by the company Chef, Inspec allows users to write automated tests for their applications and infrastructure, validating that they meet specific compliance and security requirements. Key features of Inspec include: 1. **Human-Readable DSL**: Inspec uses a domain-specific language (DSL) that is easy for both developers and non-developers to understand, enabling clear and concise test definitions.
Contract theory is a field of study in economics and legal studies that examines how individuals and organizations formulate contracts and agreements in the presence of uncertainty and varying information. It focuses on the design, enforcement, and implications of contracts in various contexts, considering factors such as incentives, moral hazards, and the allocation of risks among contracting parties.
Mean-field game theory (MFG) is a mathematical framework used to analyze strategic interactions among a large number of agents, each of whom makes decisions based on their own objectives while considering the collective impact of all agents on the system. The essential idea of MFG is that as the number of players becomes very large, the effect of any individual player on the overall dynamics becomes negligible. Instead, each player interacts with the statistical distribution of all other players.
The Modified Dietz method is a performance measurement technique used to evaluate the return on an investment portfolio over a specific time period. It accounts for the timing of cash flows in and out of the portfolio, which is crucial for accurately assessing performance, especially when there are multiple transactions throughout the measurement period. ### Key Features of the Modified Dietz Method: 1. **Cash Flow Adjustment**: The method adjusts for cash flows by giving different weights to cash flows based on when they occur within the period.
The Motzkin-Taussky theorem is a result in the field of linear algebra and matrix theory, particularly in the context of the properties of certain matrices. It addresses the determinants of matrices that are dominated by certain types of comparisons among their entries. Specifically, the theorem states that if \( A \) is an \( m \times n \) matrix that is non-negative (i.e.
Holding Period Return (HPR) is a measure of the total return on an investment over the period it is held. It considers both the income generated by the investment (such as dividends or interest) and any capital gains or losses realized during the holding period. HPR can be expressed as a percentage and is useful for investors to evaluate the performance of their investments over a specific timeframe.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
