Sifting Function Partition for the Goldbach Problem

open access: yes, 2008
All sieve methods for the Goldbach problem sift out all the composite numbers; even though, strictly speaking, it is not necessary to do so and which is, in general, very difficult. Some new methods introduced in this paper show that the Goldbach problem can be solved under sifting out only some composite numbers.

Linking the key physiological functions of essential micronutrients to their deficiency symptoms in plants

open access: yesNew Phytologist, Volume 242, Issue 3, Page 881-902, May 2024.
Summary In this review, we untangle the physiological key functions of the essential micronutrients and link them to the deficiency responses in plants. Knowledge of these responses at the mechanistic level, and the resulting deficiency symptoms, have improved over the last decade and it appears timely to review recent insights for each of them.

Understanding the role of boron in plant adaptation to soil salinity

open access: yesPhysiologia Plantarum, Volume 176, Issue 3, May/June 2024.
Abstract Soil salinity is a major environmental constraint affecting the sustainability and profitability of agricultural production systems. Salinity stress tolerance has been present in wild crop relatives but then lost, or significantly weakened, during their domestication. Given the genetic and physiological complexity of salinity tolerance traits,

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

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

open access: yesEFSA Journal, Volume 22, Issue 1, January 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 Guatemala.

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).

On the existence of a non-zero lower bound for the number of Goldbach partitions of an even integer

open access: yes, 2008
The Goldbach partitions of an even number greater than 2, given by the sums of two prime addends, form the non-empty set for all integers 2n with 2 ≤ n ≤ 2 × 1014.

Secure Communication Protocols, Secret Sharing and Authentication Based on Goldbach Partitions

open access: yes, 2017
This thesis investigates the use of Goldbach partitions for secure communication protocols and for finding large prime numbers that are fundamental to these protocols.
