Popular Cultural Portrayals of Those Who Do Mathematics [PDF]

open access: yes, 2004
This article examines the popular cultural portrayals of mathematicians, but also anyone who does mathematics. Themes occurring in comic strips, television programs, literature, and, especially, in the movies are examined.

On Some Conjectures Related to the Goldbach Conjecture

open access: yesRocky Mountain Journal of Mathematics, 2006
The author first shows that every sufficiently large integer \(n\) can be written as the sum of a square and a \(P_3\) (an integer is called a \(P_r\), when it has at most \(r\) prime factors counted with multiplicity), and points out that in the latter representation, the \(P_3\) may be replaced by a \(P_2\) when \(n\) is not a square, by the work of \

Oppression‐based stressors, posttraumatic stress symptoms, and self‐injurious thoughts and behaviors among a national sample of queer adolescents of color

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Oppression‐based stressors (OBS; e.g., heterosexism‐based stressors) are associated with a higher risk of trauma‐related symptoms and self‐injurious thoughts and behaviors (SITB) for queer (e.g., lesbian, gay, bisexual) adolescents. However, prior research has yet to examine posttraumatic stress symptoms (PTSS) and SITB in the context of the ...

Linnik's approximation to Goldbach's conjecture, and other problems

open access: yes, 2015
We examine the problem of writing every sufficiently large even number as the sum of two primes and at most $K$ powers of 2. We outline an approach that only just falls short of improving the current bounds on $K$.

Distinct Foliar Uptake Pathways for Phosphorus and Nano‐Hydroxyapatite in Potato Revealed By Synchrotron μCT and ³³P Imaging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Potato (Solanum tuberosum L.) has a high phosphorus (P) requirement, yet its shallow root system and the strong P‐fixing capacity of many soils limit the effectiveness of soil fertilisation. Foliar application of nano‐hydroxyapatite particles (nHAPs) has emerged as a promising alternative P fertilisation practice.

Random Diophantine equations in the primes

open access: yesMathematika, Volume 72, Issue 3, July 2026.
Abstract We consider equations of the form a1x1k+⋯+asxsk=0$a_{1}x_{1}^{k}+\cdots +a_{s}x_{s}^{k}=0$ where the variables xi$x_{i}$ are all taken to be primes. We define an analogue of the Hasse principle for solubility in the primes (which we call the prime Hasse principle), and prove that, whenever k⩾2$k\geqslant 2$, s⩾3k+2$s\geqslant 3k+2$, this holds

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 ...

Reversing Lanmodulin's Metal‐Binding Sequence in Short Peptides Surprisingly Increases the Lanthanide Affinity

open access: yesAngewandte Chemie, Volume 137, Issue 46, November 10, 2025.
Accidentally reversing the lanthanide‐binding sequences of lanmodulin‐inspired short peptides lead to the serendipitous discovery of a set of peptides with a one order of magnitude higher lanthanide‐binding affinity than the uncapped peptides synthesised in the correct direction.

If You Believe You Believe, You Believe. A Constitutive Account of Knowledge of One’s Own Beliefs [PDF]

open access: yes, 2017
Can I be wrong about my own beliefs? More precisely: Can I falsely believe that I believe that p? I argue that the answer is negative. This runs against what many philosophers and psychologists have traditionally thought and still ...
