Extracellular matrix remodeling upregulates hippocampal neurogenic niche stiffness and impairs neurogenesis in Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Preserving adult hippocampal neurogenesis alleviates cognitive deficits in Alzheimer's disease (AD), yet how biophysical alterations in such as stiffness in the neurogenic niche regulate neurogenesis remains unclear. METHODS Stiffness in the hippocampal dentate gyrus subgranular cell zone (SGZ) of 5×FAD mice was measured using ...

2-d CA variation with asymmetric neighborship for pseudorandom number generation [PDF]

open access: yes, 2004
This paper proposes a variation of 2-d cellular automata (CA) adopting a simpler structure than the normal 2-d CA and a unique neighborship characteristic – asymmetric neighborship.

Yet Another Pseudorandom Number Generator [PDF]

open access: yes, 2017
We propose a novel pseudorandom number generator based on R¨ossler attractor and bent Boolean function. We estimated the output bits properties by number of statistical tests.

nD-NDHS: An n-Dimensional Non-Degenerate Hyperchaotic System with Controllable All-Positive Lyapunov Exponents

open access: yesMathematics
Constructing scalable, non-degenerate, and intensity-tunable high-dimensional hyperchaotic maps is a key challenge for chaotic cryptography. Existing n-dimensional real-valued chaotic systems frequently suffer from dynamical degradation, limited ...

FPGA-Based Chaotic Oscillator Designs and Performance Analysis

open access: yesChaos and Fractals
Chaotic systems are highly sensitive to initial conditions, where even minute changes can result in vastly different outcomes. The non-linear nature of chaotic systems prevents them from reaching a stable state, instead exhibiting continuous change ...
