Many block ciphers and hash functions require the diffusion property of Maximum Distance Separable (MDS) matrices. Serial matrices with the MDS property obtain a trade-off between area requirement and clock cycle performance to meet the needs of lightweight cryptography. In this paper, we propose a new class of serial-type matrices called Diagonal-Serial Invertible (DSI) matrices with the spars...

BACKGROUND Matrix metalloproteinase -2 (gelatinase-A, Mr 72,000 type IV collagenase, MMP-2) and -9 (gelatinase-B, Mr 92,000 type IV collagenase, MMP-9) are key molecules that play roles in tumor growth, invasion, tissue remodeling, metastasis and stem-cell regulation by digesting extracellular matrix barriers. MMP-2 and -9 are well known to impact on solid cancer susceptibility, whereas, in hem...

Myelodysplastic syndromes (MDSs) are a clonal bone marrow (BM) disease characterized by ineffective hematopoiesis, dysplastic maturation and progression to acute myeloid leukemia (AML). Methylation silencing of HRK has been found in several human malignancies. In this study, we explored the association of HRK methylation status with its expression, clinical parameters and MDS subtypes in MDS pa...

Privacy is an important feature in transmission of data. Due to continuous flow data over network, there may be a chance attacks on sensitive data, either passive or active. To provide security, Cryptography plays vital role by scrambling into unreadable form. Several techniques have been developed security for digital transmission. AES one the efficient encryption engaged past decade. There ev...

INTRODUCTION Myelodysplastic syndromes (MDS) are characterized by bone marrow failure due to disturbed bone marrow maturation. MDS is associated with increased risk of transformation to acute myeloid leukemia (AML) and features of immunological dysregulation. MATERIALS AND METHODS Serum levels of 47 soluble immune mediators were examined in samples derived from 49 MDS patients (35 low-risk an...

Volatile organic compounds (VOCs) were monitored online at three photochemical assessment monitoring stations (MDS, WQS and HGS) in the Pearl River Delta region during summer of 2016. Measured levels VOCs MDS, HGS sites 34.78, 8.54 8.47 ppbv, respectively, with aromatics alkenes as major ozone precursors to secondary aerosol (SOA). The positive matrix factorization (PMF) model revealed that mai...

The Hill Cipher is a classical symmetric cipher which breaks plaintext into blocks of size m and then multiplies each block by an m × m key matrix to yield ciphertext. However, it is well known that the Hill cipher succumbs to cryptanalysis relatively easily. As a result, there have been efforts to strengthen the cipher through the use of various techniques e.g. permuting rows and columns of th...

Let q denote the finite field GF (q) and let b be a positive integer. MDS codes over the symbol alphabet b q are considered that are linear over q and have sparse (“low-density”) parity-check and generator matrices over q that are systematic over bq . Lower bounds are presented on the number of nonzero elements in any systematic parity-check or generator matrix of an q-linear MDS code over bq, ...

Two of many criteria a good MDS matrix are being involutory and having few different elements. This paper investigates the number entries in an matrices order 1, 2, 3, 4 over finite fields characteristic two. There at least three four elements with, respectively, four,
