Resumen
File size or large files are not only a problem in terms of storage, but also another problem when communication between computers. Data usage with a larger size will take longer transfer times compared to data that has a smaller size. Therefore to overcome this problem you can use data compression. Seeing the compression of data compression, data compression is needed that can reduce the size of the data, so that it gains the advantage of reducing the use of external storage media space, accelerating the process of transferring data between storage media, data utilization used in this study i

Resumen
In the process of managing multiple images or images, with larger image sizes or images that can hold longer storage and larger storage, it is needed more often as it cannot be contained on storage media and is not conveyed, thus opening up free space in memory storage media. So to make a lot of free space and have a data size that is not large on the storage media, a compression method is needed which means to shorten the required bit size. Punctured Elias Algorithm Code can be used to obtain information about the compression performed by compressing images to provide benefits in storage and

The rapid development of information technology requires users to be more careful in maintaining data confidentiality and security so that data is not known or manipulated by other parties. Data security is very important for users, data security can be maintained by everyone. Cryptography is one of the security tools used to encode a document file. One of them is by using the Massey-Omura algorithm, which is an asymmetric cryptographic algorithm, so that it has different keys for encryption and decryption.

Resumen
Transpositions are large-scale mutational events that occur when a block of genes moves from a region of a chromosome to another region within the same chromosome. The transposition distance problem is the minimum number of transpositions required to transform one genome into another. Recently, Bulteau et al. [Bulteau L, Fertin G, Rusu U, Automata, Languages and Programming, Vol. 6755 of Lecture Notes in Computer Science, pp. 654–665, Springer Berlin, Heidelberg, 2011] proved that finding the transposition distance is a NP-Hard problem.

Glacial velocities were derived using a cross-correlation algorithm, and changes in the medial moraines were interpreted based on Landsat images.

Due to antibody cross-reactivity, MAC-ELISA-positive samples may be confirmed with a time-consuming plaque reduction neutralization test (PRNT).

Abstract Platelet refractoriness occurs when a patient fails to achieve appropriate platelet count increment following platelet (plt) transfusion. Approximately 30% to 40% of cases are due to human leukocyte antigen (HLA) alloantibodies and 2% to 10% are due to human platelet antigen (HPA) alloantibodies, which can be detected by various assays. The results of these tests are then used to guide selection of appropriate units, such as crossmatch-compatible (XM) and HLA-matched (HLAm) plts.

Resumen
Abstract Background: Diagnosis of heparin-induced thrombocytopenia (HIT) requires certain clinical features along with the detection of platelet activating antibodies induced by heparin interaction with platelet factor 4 (PF4). Although the PF4 enzyme-linked immunoassay (ELISA) is a highly sensitive laboratory test, it is not specific. Adding excess heparin to the sample can confirm a positive PF4 ELISA result when it decreases antibody binding by 50% or more, potentially improving the specificity of the assay. We sought to determine the clinical value of the PF4 ELISA and confirmatory test by

Resumen
Markers of intestinal inflammation have been proposed for inclusion in Clostridium difficile diagnostic algorithms. Faecal calprotectin (f-Cp), a sensitive marker of intestinal inflammation, was evaluated for utility in C. difficile diagnosis in the hospital setting. One hundred and twenty C. difficile positive and 99 C. difficile negative faecal samples of hospital-acquired diarrhoea were analysed for f-Cp using a quantitative ELISA. C. difficile positivity was confirmed using ELISAs for either toxins (n = 45) or glutamate dehydrogenase (GDH) with toxin gene confirmation (n = 75). Non-paramet

Resumen
Abstract This study investigated the ability of two methods to detect adulteration of goat cheeses via the addition of cow's milk, with a negligible effect on the raw materials. Cheeses were produced from a mixture of goat's and cow's milk and were then analyzed by Fourier transform near-IR (FT-NIR) spectroscopy and competitive ELISA. The cheese spectra were scanned in the spectroscope in reflectance mode on an integrating sphere at 80 scans and a resolution of 4 cm−1. The spectra were evaluated via discriminant analysis, and a calibration was created via a partial least-squares algorithm to q

Known human coronaviruses are believed to have originated in animals and made use of intermediate hosts for transmission to humans. The intermediate hosts of most of the human coronaviruses are known, but not for HCoV-NL63. This study aims to assess the possible role of some major domestic livestock species as intermediate hosts of HCoV-NL63. We developed a testing algorithm for high throughput screening of livestock sera with ELISA and confirmation with recombinant immunofluorescence assay testing for antibodies against HCoV-NL63 in livestock.
