The densely packed decimal (DPD) encoding for secondary and primary storage of three binary coded decimal (BCD) digits is included in the IEEE 754-2019 standard for decimal floating-point arithmetic. Binary coded chiliad (BCC) representation of 3 BCD digits (i.e. radix-1000) will achieve equi-effici...

There are proposed run-length encoding algorithms to compress grayscale images lossless and loosy compression taking into account the likelihood of the occurrence of pixel values and providing thereby increasing the compression ratio.

The modified algorithms length coding to compress grayscale images without losses that are different from the basic algorithm taking into account the likelihood of the occurrence of pixel values and images that reduce the size of the encoded data.

Some algorithms of probabilistic coding of bits series lengths based on the confirmation of bit repetition and differing with an explicit or implicit indication of the length of the repetition symbol are proposed. The efficiency of these algorithms using for lossless compression of bit planes of hal...

Novel fluorescence and SERS encoded microspheres based on poly(glycidyl methacrylate) (PGMA) microspheres were developed by a controllable approach. The microspheres were encoded by four fluorescence dyes and three surface enhanced Raman spectra (SERS) probes. Multiple dyes could be simultaneously i...

Nowadays, cybersecurity has grown into a more significant and difficult sci-entific issue. The recognition of threats and attacks meant for knowledge and safety on the internet is growing harder to detect. Since cybersecurity guar-antees the privacy and security of data sent via the Internet, it is...

Developmental dyslexia (DD) is associated with phonological deficits. In this article, we will discuss the phonological deficits occurring in DD by applying psycholinguistic models of speech production (Levelt et al., 1999; Dell, 1986). According to these models, output phonology is created through...

This study presents a novel two-dimensional hyperchaotic map, referred to as the 2D exponent-logarithm-sine chaotic map (2D-ELSCM), which is intricately designed through the interplay of exponential, logarithmic, and sine functions. To comprehensively evaluate the chaotic performance of the 2D-ELSCM...

A pair of primers were designed to amplify a fragment of AMP gene, encoding merely mature part of β-lactamase with no promoter and signal peptide (△P△SP Amp), from pUC18. The gene was cloned into pGEM-T-EASY vector, and cut with EcoR Ⅰ. The recovered △P△SP Amp gene was then cloned and inserted betwe...

In recent years, hybrid chaotic image encryption schemes combined with the DNA encryption technology or other technologies have become a research focus of many researchers. However, some researchers neglect security analyses of proposed schemes under the chosen plaintext attack, therefore leaving se...
