The striatum is an early, accurate indicator of amyloid burden using [11C]PiB in Down syndrome: Comparison of two radiotracers

Alzheimer's &Dementia, Volume 21, Issue 4, April 2025.
Abstract INTRODUCTION Adults with Down syndrome demonstrate striatum‐first amyloid accumulation with [11C]Pittsburgh Compound‐B (PiB) positron emission tomography (PET) imaging, which has not been replicated with [18F]florbetapir (FBP). Early striatal accumulation has not been temporally quantified with respect to global cortical measures.

Some properties and extended Binet’s formula for the class of bifurcating Fibonacci sequence

Ratio Mathematica
One of the generalizations of Fibonacci sequence is a -Fibonacci sequence, which is further generalized in several other ways, some by conserving the initial conditions and others by conserving the related recurrence relation.

N–3 Fatty Acid Supplementation in Mothers and Infants for Childhood Psychomotor and Cognitive Development: An Updated Systematic Review and Meta‐Analysis

Maternal &Child Nutrition, Volume 21, Issue 2, April 2025.
This systematic review and meta‐analysis showed that supplementation with n–3 polyunsaturated fatty acid during pregnancy or breastfeeding in mothers has increased language abilities. Furthermore, direct supplementation in term infants can improve intelligence in later childhood.

Twisted rational zeros of linear recurrence sequences

Journal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract We introduce the notion of a twisted rational zero of a nondegenerate linear recurrence sequence (LRS). We show that any nondegenerate LRS has only finitely many such twisted rational zeros. In the particular case of the Tribonacci sequence, we show that 1/3$1/3$ and −5/3$-5/3$ are the only twisted rational zeros that are not integral zeros.

DCMCF: Dynamic Cross‐Modal Context Fusion for Image‐Based Person Search

IET Image Processing, Volume 19, Issue 1, January/December 2025.
This paper proposes dynamic cross‐modal context fusion, a novel framework for image‐based person search that dynamically enhances multi‐view visual representations with automatically generated multi‐level textual descriptions. By integrating cross‐modal context through adaptive fusion and text‐guided re‐ranking, our method achieves state‐of‐the‐art ...

A Brief Study on the k-Dimensional Repunit Sequence

Axioms
In this paper, we aim to introduce and investigate the bidimensional, tridimensional and k-dimensional extension of Repunit numbers, with a particular focus on their recurrence relations, key properties, and various sum identities.

On Gersenne Sequence: A Study of One Family in the Horadam-Type Sequence

Axioms
This study introduces an innovative approach to Mersenne-type numbers. This paper introduces a new class of numbers, which we call Gersenne numbers. The aim of this paper is to define the Gersenne sequence and to investigate some of their properties ...
