PURPOSE To determine the relationship between maternal serum zinc (Zn) levels and birth weight of the offspring and their correlation with cord blood Zn, insulin-like growth factor (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) levels. METHOD 22 term small-for-gestational-age (SGA) and 34 term appropriate-for-gestational-age (AGA)(More)
MaximumDistance Separable (MDS) andMaximumDistance Binary Linear (MDBL) codes are used as diffusion layers in the design of the well-known block ciphers like the Advanced Encryption Standard, Khazad, Camellia, and ARIA. The reason for the use of these codes in the design of block ciphers is that they provide optimal diffusion effect to meet security of a(More)
INTRODUCTION Antimicrobial resistance has decreased eradication rates for Helicobacter pylori infection, and recent reports from different countries report eradication rates lower than 80% with triple therapy. The aim of this pilot study was to investigate the efficacy of standard triple eradication regimen in long-term aspirin users. METHOD The study(More)
In the literature, there are several proposed block ciphers like AES, Square, Shark and Hierocrypt which use S-boxes that are based on inversion mapping over a finite field. Because of the simple algebraic structure of S-boxes generated in this way, these ciphers usually use a bitwise affine transformation after the inversion mapping. In some ciphers like(More)
AES block cipher includes a linear transformation called MixColumns which transforms 32-bit input to 32-bit output. This transformation has the property that makes linear and differential attacks harder. In this study, we obtain a model of MixColumns transformation in bits. In fact, there are two reasons for obtaining this model. The first one is to show(More)
