African swine fever virus (ASFV) is a large, double-stranded DNA virus in the Asfarviridae family. [1] It is the causative agent of African swine fever (ASF). The virus causes a hemorrhagic fever with high mortality rates in domestic pigs ; some isolates can cause death of animals as quickly as a week after infection.
Here, k ≈ 1.38 × 10 −23 J/K is the Boltzmann constant and kT 0 is the available noise power density (the noise is thermal noise, Johnson noise). As a numerical example: A receiver has a bandwidth of 100 MHz, a noise figure of 1.5 dB and the physical temperature of the system is 290 K.
The instrument detection limit (IDL) is the analyte concentration that is required to produce a signal greater than three times the standard deviation of the noise level. This may be practically measured by analyzing 8 or more standards at the estimated IDL then calculating the standard deviation from the measured concentrations of those standards.
"2.5.1: Number of plant and animal genetic resources for food and agriculture secured in either medium or long term conservation facilities. 2.5.2: Proportion of local breeds, classified as being at risk, not at risk or unknown level of risk of extinction." [37] Although policies can have some negative consequences, they are nonetheless important.
Scientific Data is a peer-reviewed open access scientific journal published by Nature Research since 2014. [1] It focuses on descriptions of data sets relevant to the natural sciences , medicine , engineering and social sciences , [ 2 ] which are provided as machine-readable data , complemented with a human oriented narrative.
The Louvain method for community detection is a greedy optimization method intended to extract non-overlapping communities from large networks created by Blondel et al. [ 1 ] from the University of Louvain (the source of this method's name).
[2] Immunoassays became considerably simpler to perform and more popular when techniques for chemically linked enzymes to antibodies were demonstrated in the late 1960s. [3] In 1983, Professor Anthony Campbell [4] at Cardiff University replaced radioactive iodine used in immunoassay with an acridinium ester that makes its own light ...
A typical molecular beacon structure can be divided in 4 parts: 1) loop, an 18–30 base pair region of the molecular beacon that is complementary to the target sequence; 2) stem formed by the attachment to both termini of the loop of two short (5 to 7 nucleotide residues) oligonucleotides that are complementary to each other; 3) 5' fluorophore ...
