The other class of mills are "attrition" or grinding mills. Impact mills pulverize the material upon impact. The feasibility of impact mills was greatly enhanced by the mechanization and engineeri... |
https://en.wikipedia.org/wiki/Sonoporation | Sonoporation, or cellular sonication, is the use of sound in the ultrasonic range for increasing the permeability of the cell plasma membrane. This technique is usually used in molecular biology and non-viral gene therapy in order to allow uptake of large molecules such as DNA into the cell, in a cell disruption proces... |
https://en.wikipedia.org/wiki/Variable%20structure%20control | Variable structure control (VSC) is a form of discontinuous nonlinear control. The method alters the dynamics of a nonlinear system by application of a high-frequency switching control. The state-feedback control law is not a continuous function of time; it switches from one smooth condition to another. So the structur... |
https://en.wikipedia.org/wiki/List%20of%20omics%20topics%20in%20biology | Inspired by the terms genome and genomics, other words to describe complete biological datasets, mostly sets of biomolecules originating from one organism, have been coined with the suffix -ome and -omics. Some of these terms are related to each other in a hierarchical fashion. For example, the genome contains the ORFe... |
https://en.wikipedia.org/wiki/Dislocation%20creep | Dislocation creep is a deformation mechanism in crystalline materials. Dislocation creep involves the movement of dislocations through the crystal lattice of the material, in contrast to diffusion creep, in which diffusion (of vacancies) is the dominant creep mechanism. It causes plastic deformation of the individual c... |
https://en.wikipedia.org/wiki/Real-time%20adaptive%20security | Real-time Adaptive Security is the network security model necessary to accommodate the emergence of multiple perimeters and moving parts on the network, and increasingly advanced threats targeting enterprises. Adaptive security can watch a network for malicious traffic and behavioral anomalies, ferret out end point vul... |
https://en.wikipedia.org/wiki/Choice%20architecture | Choice architecture is the design of different ways in which choices can be presented to decision makers, and the impact of that presentation on decision-making. For example, each of the following:
the number of choices presented
the manner in which attributes are described
the presence of a "default"
can influenc... |
https://en.wikipedia.org/wiki/BESYS | BESYS (Bell Operating System) was an early computing environment originally implemented as a batch processing operating system in 1957 at Bell Labs for the IBM 704 computer.
Overview
The system was developed because Bell recognized a "definite mismatch…between the 704's internal speed, the sluggishness of its on-line ... |
https://en.wikipedia.org/wiki/Local%20trace%20formula | In mathematics, the local trace formula is a local analogue of the Arthur–Selberg trace formula that describes the character of the representation of G(F) on the discrete part of L2(G(F)), for G a reductive algebraic group over a local field F. |
https://en.wikipedia.org/wiki/Silicon%20drift%20detector | Silicon drift detectors (SDDs) are X-ray radiation detectors used in x-ray spectrometry (XRF and EDS) and electron microscopy. Their chief characteristics compared with other X-ray detectors are:
high count rates
comparatively high energy resolution (e.g. 125 eV for Mn Kα wavelength)
Peltier cooling
Working principle

https://en.wikipedia.org/wiki/Weak%20coloring | In graph theory, a weak coloring is a special case of a graph labeling. A weak -coloring of a graph assigns a color } to each vertex , such that each non-isolated vertex is adjacent to at least one vertex with different color. In notation, for each non-isolated , there is a vertex with and .
