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

Resumen
Hoy el procesamiento de imágenes se volvió cotidiano debido a la masificación de equipos que generan, almacenan y muestran imágenes digitales. Esto ocurre porque son necesarias (o deseables) imágenes con mayor resolución y tamaño a medida que se encuentran nuevas aplicaciones que dependen de ellas y el recambio de equipos no siempre es una opción viable. La reconstrucción de imágenes (ya sea ampliación, aumento de resolución o definición de detalles) se hace a través de algoritmos matemáticos.

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
The front-line assay for the presumptive serodiagnosis of acute Japanese encephalitis virus (JEV) and West Nile virus (WNV) infections is the premembrane/envelope (prM/E)-specific IgM antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA). Due to antibody cross-reactivity, MAC-ELISA-positive samples may be confirmed with a time-consuming plaque reduction neutralization test (PRNT). In the present study, we applied a previously developed anti-nonstructural protein 1 (NS1)-specific MAC-ELISA (NS1-MAC-ELISA) on archived acute-phase serum specimens from patients with confirmed JEV and WNV

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
ABSTRACT Immunoassay-based anti-nuclear antibody (ANA) screens are increasingly used in the initial evaluation of autoimmune disorders, but these tests offer no “pattern information” comparable to the information from indirect fluorescence assay-based screens. Thus, there is no indication of “next steps” when a positive result is obtained. To improve the utility of immunoassay-based ANA screening, we evaluated a new method that combines a multiplex immunoassay with a k nearest neighbor (kNN) algorithm for computer-assisted pattern recognition. We assembled a training set, consisting of 1,152 s

Resumen
AbstractAvian influenza virus (AIV) subtypes H5 and H7 can infect poultry causing low pathogenicity (LP) AI, but these LPAIVs may mutate to highly pathogenic AIV in chickens or turkeys causing high mortality, hence H5/H7 subtypes demand statutory intervention. Serological surveillance in the European Union provides evidence of H5/H7 AIV exposure in apparently healthy poultry. To identify the most sensitive screening method as the first step in an algorithm to provide evidence of H5/H7 AIV infection, the standard approach of H5/H7 antibody testing by haemagglutination inhibition (HI) was compar

Resumen
ABSTRACT A diagnostic algorithm was developed to differentiate between human infections of West Nile virus (WNV) and St. Louis encephalitis virus (SLEV) using positive-to-negative (P/N) ratios derived from the immunoglobulin M capture enzyme-linked immunosorbent assay (MAC-ELISA). To validate this algorithm, we tested 1,418 serum and cerebrospinal fluid (CSF) samples from confirmed WNV and SLEV infections collected during the WNV epidemic of 2002 in the United States. WNV P/N-to-SLEV P/N ratios (W/S ratios) were calculated and used to identify the infecting virus. These results were compared t

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

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
