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

Angewandte 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.

GRAPH AND GOLDBACH CONJECTURE [PDF]

International Journal of Pure and Apllied Mathematics, 2013
In this paper, the new direction of proof of Gold Bach conjecture "every even number n greater than 2 can be expressed as a sum of two primes" has been forwarded with the help of some graph theoretic concept which seems to be very easy. This new direction gives the application graph theory in prov- ing the conjectural problem Gold Bach conjecture of ...

The ternary Goldbach problem with primes in arithmetic progressions modulus prime numbers

AIMS Mathematics
In this paper, assuming the Landau's conjecture, we obtained an explicit numerical upper bound for the prime modulus of arithmetic progressions, in which the ternary Goldbach problem is solvable.

A Small World Network of Prime Numbers

, 2006
According to Goldbach conjecture, any even number can be broken up as the sum of two prime numbers : $n = p + q$. We construct a network where each node is a prime number and corresponding to every even number $n$, we put a link between the component ...

On the Binary Goldbach Conjecture: Analysis and Alternate Formulations Using Projection, Optimization, Hybrid Factorization, Prime Symmetry and Analytic Approximation

Mathematics and Computer Science
An analysis, based on different mathematical approaches, of the binary Goldbach conjecture −which states that every even integer s≥6 is the sum of two odd primes, called Goldbach primes− is presented.

Associations between health care access and posttraumatic stress disorder symptoms among rural and urban lesbian, gay, bisexual, transgender, and queer adults

Journal of Traumatic Stress, EarlyView.
Abstract Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals experience elevated rates of trauma exposure, minority stress, and posttraumatic stress disorder (PTSD). Yet, research examining how geographic location and LGBTQ+ identity shape PTSD outcomes is scant, particularly studies considering structural facilitators and barriers ...

On Alternating and Symmetric Groups Which Are Quasi OD-Characterizable

, 2017
Let $\Gamma(G)$ be the prime graph associated with a finite group $G$ and $D(G)$ be the degree pattern of $G$. A finite group $G$ is said to be $k$-fold OD-characterizable if there exist exactly $k$ non-isomorphic groups $H$ such that $|H|=|G|$ and $D(H)=

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

Addiction, EarlyView.
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 ...

A Detailed Proof of the Strong Goldbach Conjecture Based on Partitions of a New Formulation of a Set of Even Numbers

Asian Research Journal of Mathematics
The Strong Goldbach's conjecture, a fundamental problem in Number Theory, asserts that every even integer greater than 2 can be expressed as the sum of two prime numbers.

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

The American Journal on Addictions, EarlyView.
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
