Excel and the Goldbach Comet

open access: yesSpreadsheets in Education, 2007
This article shows ways in which Excel can be used to explore the Goldbach Conjecture. We first show an elementary approach in which the Goldbach Comet is constructed by means of a table of values.

Epitaxy of ultrathin Fe3O4 films on SrTiO3(001): influence of growth parameters on the formation of coexisting (111)‐ and (001)‐oriented phases

open access: yesJournal of Applied Crystallography, Volume 59, Issue 3, Page 889-900, June 2026.
Ultrathin Fe3O4 films grown on SrTiO3(001) were systematically studied with respect to film growth parameters to clarify the coexistence of (111) and (001) orientations. X‐ray diffraction analyses reveal the formation of an intermediate (111)‐oriented phase during the initial growth stage, which persists even after preferential (001) growth is ...

THE ORDER OF NUMBERS AND THE GOLDBACH CONJECTURE

open access: yesSSRN Electronic Journal, 2023
Following will be regard the potentiality of order of numbers for the ternary Goldbach conjecture, where he claimed that “every number… is an aggregate of three prime numbers”. The order of numbers illustrates the possible combinations of prime numbers for the generation of all natural (integer) numbers.

Milestones, revisited: Iterative and nonlinear identity development in Gen‐Z

open access: yesJournal of Research on Adolescence, Volume 36, Issue 2, June 2026.
Abstract This study examined how sexual and gender identity development experiences, commonly operationalized as “milestones,” were navigated by Gen‐Z LGBTQ+ young people. Using a life‐history calendar approach, milestone‐related experiences were treated as heuristic sites of meaning‐making rather than fixed developmental benchmarks.

Zassenhaus conjecture for central extensions of S5 [PDF]

open access: yes, 2008
We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S5 and for the general linear group GLð2; 5Þ. The first result, together with others from the literature,

Profiles of parental response, intersectional microaggressions, and mental health problems among sexual and gender minority youth of color

open access: yesJournal of Research on Adolescence, Volume 36, Issue 2, June 2026.
Abstract Sexual and gender minority youth of color (SGM YOC) face compounded mental health disparities due to oppression experienced at the intersection of racism, cissexism, and heterosexism. Parental responses to youth's sexual orientation and gender identity (SOGI) are critical in shaping youth mental health outcomes, yet prior research has often ...

The 2 Goldbach's Conjectures with Proof

open access: yes, 2021
The 1741 Goldbach [1] made his most famous contribution to mathematics with the conjecture that all even numbers can be expressed as the sum of the two primes (currently Conjecture referred to as "all even numbers greater than 2 can be expressed as the ...

A meta‐analysis of sexual orientation inequities in substance use among youth

open access: yesAddiction, Volume 121, Issue 5, Page 1048-1063, May 2026.
Abstract Background and Aims Sexual minority youth report significantly higher rates of substance use than heterosexual youth, yet a comprehensive and systematic evaluation and synthesis of the magnitude of this inequity has not been conducted. The purpose of this study was to conduct a meta‐analysis to assess the magnitude of overall inequities in ...

PROPOSAL OF DEMONSTRATION OF THE GOLDBACH’S CONJECTURE

open access: yesINTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH, 2023
The Goldbach’s conjecture is the unproven mathematic assertion which states : All whole even number greater than 2 can be written as the sums of two prime numbers. It was formulated in 1742 by Christian Goldbach, it is one of the oldest unsolved problem of the theorie of number and mathematics.

Substance use and sexual orientation among adolescents: Differences by age group and sex in the 2023 National Survey of Drug Use and Health

open access: yesThe American Journal on Addictions, Volume 35, Issue 3, Page 396-403, May 2026.
Abstract Background and Objectives Adolescent substance use is a critical public health concern with significant long‐term consequences, yet research on disparities by sexual orientation remains limited. Despite the unique stressors faced by sexual minority youth—particularly bisexual individuals—that increase their risk for substance use, most studies
