The mixture enthalpy minus the sum of the unmixed component enthalpies at the same temperature and pressure. Its sign does not alone determine miscibility, which depends on the full Gibbs free energy.
The sum of specific enthalpy and macroscopic kinetic energy per unit mass. In a steady adiabatic flow without shaft work, its change is determined by the change in external potential energy. At essentially constant external potential energy, it is conserved through a stationary nonradiating shock wave even though entropy increases.
A nonzero position-space wavefunction representing an energy eigenstate. For a time-independent Quantum Hamiltonian, its time evolution is a global phase, so its position probability density is stationary.
Phagocytosis encloses a large extracellular particle by extending and closing the cell membrane around it. It is one possible conceptual route for internalizing a symbiotic partner, but a modern phagocytic pathway should not be assumed to have existed before eukaryotic organization evolved.
clathrin-mediated endocytosis internalizes selected surface material through assembly of adaptors and a clathrin coat, membrane deformation, scission and subsequent coat release. Counts of coated puncta alone do not distinguish initiation, successful internalization and stalled intermediates.
synaptic vesicle recycling retrieves and reuses membrane and components after synaptic release. Uptake, uncoating, sorting and preparation for subsequent release are distinct measurable steps.
For quantities , the th elementary symmetric sum is , with . Every term uses distinct indices, and permuting the inputs leaves the sum unchanged.
For three inputs, , , and . Expanding the product gives . These are Vieta's formulas, linking coefficients of a polynomial to symmetric expressions in its roots.
An interaction of three electroweak gauge bosons, especially and . Their Standard Model coefficients and momentum dependence come from the cubic and quartic Yang-Mills self-interactions after neutral-field mixing. W-pair production tests their relative strengths through interference with neutrino exchange; effective anomalous couplings require a stated convention and consistency constraints.[ref]
Measurement of Triple-Gauge-Boson Couplings of the W Boson at LEP by L3 Collaboration. 2004 abstract: measured charged triple-gauge parameters
An approximation defining an effective mass near a band extremum. A fitted positive curvature gives positive effective mass.
An amplifier that converts input charge to voltage through a feedback capacitance; used to read a piezoelectric stress sensor while controlling electrical loading.
detective quantum efficiency is the ratio of output to input squared signal-to-noise ratio for a specified measurement convention, often evaluated by spatial frequency. It describes information preservation by a detector rather than just its pixel size.
A cold field emission gun produces an electron beam by field emission without the high emitter temperature of a thermal source. A narrow energy spread can improve temporal coherence and high-frequency contrast in cryo-electron microscopy.
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.
