Cell-free protein array technology produces protein microarrays by performing in vitro synthesis of the target proteins from their DNA templates. This method of synthesizing protein microarrays overcomes the many obstacles and challenges faced by traditional methods of protein array production [1] that have prevented widespread adoption of protein microarrays in proteomics.
One null model of utility in the study of complex networks is that proposed by Newman and Girvan, consisting of a randomized version of an original graph , produced through edges being rewired at random, under the constraint that the expected degree of each vertex matches the degree of the vertex in the original graph.

A happy number for a given base and a given power is a preperiodic point for the perfect digital invariant function , such that the -th iteration of , is equal to the trivial perfect digital invariant , and an unhappy number is one such that there exists no such .
A solar power tower consists of an array of dual-axis tracking reflectors that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.
A U.S. Marine Corps MV-22 Osprey carrying 21 U.S. Marines and one United States Navy hospital corpsman crashes on landing at Bellows Air Force Station in Waimanalo, Hawaii, and catches fire, killing one Marine and injuring the other 21 people aboard, all of whom are sent to hospitals. [216] 18 May
The system, Japan's first full radar, was designated Mark 1 Model 1. (This type of designation is shortened herein to the numbers only; e.g., Type 11.) The system operated at 3.0 m (100 MHz) with a peak-power of 40 kW. Dipole arrays with mat-type reflectors were used in separate antennas for transmitting and receiving.
RISC-V [b] (pronounced "risk-five" [2]: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. . The project began in 2010 at the University of California, Berkeley, transferred to the RISC-V Foundation in 2015, and on to RISC-V International, a Swiss non-profit entity, in November 20
