Lillian Lee is a prominent computer scientist known for her contributions to the fields of natural language processing (NLP) and human-computer interaction. She is a professor in the Department of Computer Science at Cornell University and is also affiliated with the Department of Linguistics. Her research interests encompass computational linguistics, text mining, sentiment analysis, and the intersection of computer science with social science.
A Linear Bounded Automaton (LBA) is a type of computational model that is a restricted form of a Turing machine. Specifically, an LBA operates on an input tape of finite length and is constrained to use only a bounded amount of tape space relative to the length of the input. Here are some key characteristics of LBAs: 1. **Tape Length**: An LBA has a tape whose length is linearly bounded by the length of the input.
In mathematics, particularly in the field of functional analysis, a **linear functional** is a specific type of linear map from a vector space to its field of scalars (such as the real numbers \(\mathbb{R}\) or the complex numbers \(\mathbb{C}\)).
A linear induction motor (LIM) is an electromechanical device that generates linear motion instead of the rotational motion produced by conventional rotary motors. It operates on the principles of electromagnetic induction and uses a moving magnetic field to produce force and motion along a straight path. Here are the key components and concepts related to linear induction motors: ### Components: 1. **Stator**: The stator is the stationary part of the motor that contains a series of coils.
Lipofectamine is a brand of transfection reagents developed by Thermo Fisher Scientific. It is primarily used in molecular biology and biotechnology for the delivery of nucleic acids—such as DNA, RNA, and plasmids—into a variety of cell types. Lipofectamine formulations typically consist of cationic lipids that can form liposomes, which encapsulate the nucleic acids and facilitate their entry into cells.
A Liquid Crystal Tunable Filter (LCTF) is an optical device that uses liquid crystal technology to selectively transmit light at specific wavelengths while blocking others. Unlike traditional optical filters, which are fixed and only allow certain wavelengths to pass through, LCTFs can be dynamically adjusted to change their transmission characteristics.
The Lisbon Protocol is an agreement signed in 1992 that aimed to facilitate the continuation of the strategic arms reduction talks between the United States and the Russian Federation (along with other former Soviet states). Specifically, the protocol was an extension of earlier arms control agreements and focused on the nuclear arsenals of the signatory states.
BamHI is a type II restriction enzyme that is commonly used in molecular biology for DNA manipulation and cloning. It recognizes a specific DNA sequence and cleaves the DNA at that site. The recognition sequence for BamHI is the palindromic sequence 5'-GGATCC-3'. When BamHI cuts DNA, it produces sticky (or cohesive) ends, which are single-stranded overhangs that can facilitate the ligation of DNA fragments during cloning experiments.
The list of asteroid close approaches to Earth includes information about asteroids that come near our planet at relatively close distances. These approaches are typically measured in lunar distances (the distance from the Earth to the Moon, about 384,400 kilometers or 238,855 miles). Asteroids that make close approaches can vary in size, speed, and characteristics.
A phosphodiester bond is a type of chemical bond that forms between the phosphate group of one nucleotide and the hydroxyl group on the sugar of another nucleotide within a nucleic acid, such as DNA or RNA. This bond is crucial for the structural integrity of nucleic acids, as it creates a long chain of nucleotides joined together.
ASTM International has developed a vast array of standards encompassing numerous industries and applications. The standards designated with the prefix "D" are generally related to materials and testing processes. The range from D5001 to D6000 includes various standards in fields such as construction, materials, environmental testing, and more.
The original "MacGyver" TV series, which aired from 1985 to 1992, received various awards and nominations throughout its run. Here's a summary of its notable achievements: ### Awards: 1. **Primetime Emmy Awards**: - Won 1 Emmy Award: Outstanding Sound Editing for a Series (1991). - Nominated for additional awards in categories like Outstanding Stunt Coordination.
As of my last update in October 2021, I don't have the exact most recent figures for the life expectancy by Brazilian state.
The list of causes of death by rate typically refers to rankings or statistics that show the prevalence of different causes of death in a specific population, often based on data from health organizations like the World Health Organization (WHO) or the Centers for Disease Control and Prevention (CDC). These lists can vary by country, region, or demographic group and are usually presented as rates per 100,000 individuals.
The British Isles is home to a variety of coastal weather stations that provide valuable meteorological data for both research and public use. These stations are often maintained by national meteorological services, universities, and other organizations.
Acid guanidinium thiocyanate-phenol-chloroform extraction is a biochemical technique primarily used for the isolation and purification of RNA from biological samples. This method is effective in disrupting cellular structures and denaturing proteins, which allows for the efficient extraction of nucleic acids.
As of my last update in October 2023, here is a general overview of life expectancy in various countries in the Americas. Note that specific numbers can vary by source and may have changed since my last update. For the most accurate and up-to-date information, it’s recommended to consult resources such as the World Health Organization (WHO), World Bank, or United Nations databases.
"De rerum natura" (On the Nature of Things) is a philosophical poem by the Roman poet and philosopher Lucretius, which explores Epicurean philosophy and the nature of the universe. There have been several English translations of this work over the years. Here are some notable ones: 1. **William Ellery Leonard (1916)** - This was the first significant verse translation into English, which sought to maintain the poetic structure. 2. **H. A. R.
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.
