Electrically detected magnetic resonance
To perform a pulsed EDMR experiment, the system is first initialised by placing it in a magnetic field. This orients the spins of the electrons occupying the donor and acceptor in the direction of the magnetic field. To study the donor, we apply a microwave pulse ("γ" in the diagram) at a resonant frequency of the dono...

By scanning the frequency of the microwave pulse, we can find which frequencies are resonant, and with knowledge of the strength of the magnetic field, we can identify the donor's energy levels from the resonant frequency and knowledge of the Zeeman effect.

N50, L50, and related statistics
N50 can be described as a weighted median statistic such that 50% of the entire assembly is contained in contigs or scaffolds equal to or larger than this value. L50 Given a set of contigs, each with its own length, the L50 is defined as count of smallest number of contigs whose length sum makes up half of genome size....

N90 The N90 statistic is less than or equal to the N50 statistic; it is the length for which the collection of all contigs of that length or longer contains at least 90% of the sum of the lengths of all contigs.

NG50 Note that N50 is calculated in the context of the assembly size rather than the genome size. Therefore, comparisons of N50 values derived from assemblies of significantly different lengths are usually not informative, even if for the same genome. To address this, the authors of the Assemblathon competition came u...

D50 The D50 statistic (also termed D50 test) is similar to the N50 statistic in definition though it is generally not used to describe genome assemblies. The D50 statistic is the lowest value d for which the sum of the lengths of the largest d lengths is at least 50% of the sum of all of the lengths. U50 U50 is the le...

UL50 UL50 is the number of contigs whose length sum produces U50. UG50 UG50 is the length of the smallest contig such that 50% of the reference genome is contained in unique, target-specific contigs of size UG50 or larger.

UG50% UG50% is the estimated percent coverage length of the UG50 in direct relation to the length of the reference genome. The calculation is (100 × (UG50/Length of reference genome). The UG50%, as a percentage-based metric, can be used to compare assembly results from different samples or studies.

Examples Consider two fictional, highly simplified genome assemblies, A and B, that are derived from two different species. Assembly A contains six contigs of lengths 80 kbp, 70 kbp, 50 kbp, 40 kbp, 30 kbp, and 20 kbp. The sum size of assembly A is 290 kbp, the N50 contig length is 70 kbp because 80 + 70 is greater tha...

If the estimated or known size of the genome from the fictional species A is 500 kbp then the NG50 contig length is 30 kbp because 80 + 70 + 50 + 40 + 30 is greater than 50% of 500. In contrast, if the estimated or known size of the genome from species B is 350 kbp then it has an NG50 contig length of 50 kbp because 80...

Create another list L' , which is identical to L, except that every element n in L has been replaced with n copies of itself. The median of L' is the N50 of L. (The 10% quantile of L' is the N90 statistic.)

For example: If L = (2, 2, 2, 3, 3, 4, 8, 8), then L' consists of six 2's, six 3's, four 4's, and sixteen 8's. That is, L' has twice as many 2s as L; it has three times as many 3s as L; it has four times as many 4s; etc. The median of the 32-element set L' is the average of the 16th smallest element, 4, and 17th sm...

Eudicella gralli
Eudicella gralli, sometimes called the flamboyant flower beetle or striped love beetle, is a brightly coloured member of the scarab beetle family, in the subfamily known as flower beetles. Their shells seem to have a prismatic quality, refracting the ambient light to give the green of their carapace a rainbow tint. Thi...
