Abstract

The Advanced Encryption Standard (AES) is a symmetric-key encryption algorithm and it provides standardized authentication by using Galois/Counter Mode (GCM). Hence it is utilized in various security-constrained applications. Many of the AES-GCM applications are power and resource constrained and requires efficient hardware implementations. In this paper, different Application-Specific Integrated Circuit (ASIC) architectures of building blocks of the AES-GCM algorithms are evaluated and optimized to identify the high-performance and low-power architectures for the AES-GCM.  In AES, to obtain the least complexity S-box (Sub-Bytes), the formulations for the Galois Field (GF) subfield inversions in GF (2⁴) are optimized. By conducting exhaustive simulations for the input transitions, the average and peak power consumptions of the AES S-boxes  can be analysed by  considering the switching activities, gate-level netlists, and parasitic information and  the S-box realisation based on lookup tables (LUTs) could be area efficient when implemented utilizing the memory resources available on FPGAs.  The proposed parallel method uses two GF (2¹²⁸⁾ multipliers and it results high-throughput and low latency GCM hardware architectures which is suitable for high-performance applications.

Abstract

Background: Free fatty acids (FFAs) are associated with several cardiovascular risk factors and exert harmful effects on the myocardium.

Objective: The aim of our study was to elucidate the FFAs level in patients with coronary artery disease who are angiographically proven and normal person.

Methods and Result: A total of 30 coronary artery disease (CAD) patient and 30 healthy controls were examined for fasting plasma circulating FFA. Each subject underwent a physical examination, ECG, coronary angiography, provided blood for laboratory tests, and answered questionnaires administered by trained interviewers. Body mass index, blood pressures, tobacco consumption, diabetes, fasting cholesterol level, and circulating FFA were independent risk factors for coronary artery disease. When adjusted for confounding factors, circulating plasma FFA concentration remained an independent risk factor for coronary artery disease. Circulating plasma FFA was significantly (p<0.001**) elevated in patients with coronary artery disease when compared to normal.

Conclusions: FFA levels are an independent predictive risk factor of CAD. A possible diagnostic use of FFAs warrants further studies, but our results may underline the importance of therapeutic approaches to influence FFA metabolism.

Abstract

In a field experiment conducted on Typic Chromustert at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, the yield of chilli was significantly influenced by the levels and sources of potassium. The treatment that received 150 per cent RDK through SOP in 2 split doses recorded highest fruit yield (10.71 q ha^-1). The highest uptake of N (67.93 kg ha^-1), K (106.77 kg ha^-1) and S (15.30 kg ha^-1) were noticed with the application of potassium at the rate of 150 per cent RDK through sulphate of potash in 2 split doses.
