Proposta di Dimostrazione della variante Riemann di Lagarias (RH1) equivalente all’Ipotesi di Riemann RH, con RH1 = RH. [PDF]

open access: yes, 2007
Scopo del presente lavoro è quello di proporre una dimostrazione dell'Ipotesi di Riemann attraverso quella che tecnicamente viene definita "variante di Lagarias".

On the number of solutions of a restricted linear congruence

open access: yes, 2017
Consider the linear congruence equation $${a_1^{s}x_1+\ldots+a_k^{s} x_k \equiv b\,(\text{mod } n^s)}\text { where } a_i,b\in\mathbb{Z},s\in\mathbb{N}$$ Denote by $(a,b)_s$ the largest $l^s\in\mathbb{N}$ which divides $a$ and $b$ simultaneously.

Quality and stability of frying oils and fried foods in ultrasound and microwave–assisted frying processes and hybrid technologies

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Frying is a popular cooking method that produces delicious and crispy foods but can also lead to oil degradation and the formation of health‐detrimental compounds in the dishes. Chemical reactions such as oxidation, hydrolysis, and polymerization contribute to these changes.

Implications of Ramsey Choice principles in ZF$\mathsf {ZF}$

open access: yesMathematical Logic Quarterly, Volume 70, Issue 2, Page 255-261, May 2024.
Abstract The Ramsey Choice principle for families of n$n$‐element sets, denoted RCn$\operatorname{RC}_{n}$, states that every infinite set X$X$ has an infinite subset Y⊆X$Y\subseteq X$ with a choice function on [Y]n:={z⊆Y:|z|=n}$[Y]^n:= \lbrace z\subseteq Y: |z| = n\rbrace$.

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.

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.

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

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 ...
