A Problem in Additive Number Theory [PDF]

open access: yesTransactions of the American Mathematical Society, 1938
where all the prime factors of each hi are of a given form. A search of the literature seemed to indicate that various theorems had been conjectured but none actually proved.t For example, L. Euler stated without proof that every integer of the form 4j+2 is a sum of two primes each of the form 4j+ 1.

On Large Sum-Free Sets: Revised Bounds and Patterns

open access: yesMathematics
In this paper, we rectify two previous results found in the literature. Our work leads to a new upper bound for the largest sum-free subset of [1,n] with the lowest value in n3,n2, and the identification of all patterns that can be used to form sum-free ...

The impact of epistasis in the heterosis and combining ability analyses

open access: yesFrontiers in Plant Science, 2023
The current theoretical knowledge concerning the influence of epistasis on heterosis is based on a simplified multiplicative model. The objective of this study was to assess how epistasis affects the heterosis and combining ability analyses, assuming ...

BIT ERROR OPTIMIZATION OF CODED OFDM SYSTEM OVER RAYLEIGH FADING CHANNEL [PDF]

open access: yesJournal of Engineering and Sustainable Development, 2019
Low Density Parity-Check (LDPC) codes are one of the hottest topics in coding theory today. This code invented in the early 1960's, and it having an amazing comeback in the last few years.
