Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Kenya

open access: yesEFSA Journal, Volume 22, Issue 4, April 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Kenya. The relevance of any pest for

A Proof of Goldbach Conjecture by Using Goldbach Partition Model Table and Sieve Functions

open access: yes, 2015
Goldbach's Conjecture(GC) states that any even integer ≥ 4 can be represented by the sum of two prime numbers. This was conjectured by Christian Goldbach in 1742 and still remains unproved. In this thesis we proved GC by introducing Goldbach Partition Model Table(GPMT) and Sieve Functions(SFs).

Goldbach Approach. A possible formula for calculating binary prime partitions of even numbers.

open access: yes, 2022
Goldbach conjecture is one of the most famous open problems of mathematics, but its fame is justified by the time that this problem has been unproven and the long list of people who contribute one more piece to this puzzle, which is why this conjecture has two problems, the obvious level of difficulty, and the second is to be able to separate from all ...

Predicting the size ranking of minimal primes in the generalised Goldbach partitions

open access: yes
A scarcely known generalization of Goldbach's conjecture introduced by Hardy and Littlewood states that for every pair of (relatively prime) positive integers m1 and m2, every sufficiently large integer n satisfying certain simple congruence criteria can be $(m_1,m_2)$-partitioned as $n = m_1p+m_2q$ for some primes $p$ and $q$.

A Quadratic Root-Difference Approach to Goldbach Partitions

open access: yes
This work develops an unconditional density framework by embedding Euler's quadratic-root structure into a Hardy--Littlewood--type $\delta r$ definite-integral formulation. The aim is to describe additive density and prime-distribution behavior without relying on the Generalized Riemann Hypothesis (GRH).
