Quantitative Assessment of Randomized DNA Base Sequences Using Multi‐Model Physical Analysis for High‐Fidelity Data Storage

Advanced Science, Volume 13, Issue 7, 3 February 2026.
This study quantitatively evaluates randomized DNA sequence design for digital data storage using three physics‐based models. By applying encoding schemes with strict homopolymer constraints, the framework improves base randomness, GC balance, and error resilience. Experimental validation via PCR and Sanger sequencing confirms 95–98% decoding accuracy,

A Novel Quantised Image Sensing for Machine Vision

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper shows that the image information quantised in the range of 1 to 4 bits can be utilised for object detection and tracking without any performance degradation. Thus, it is expected that the proposed technique holds promise for use in machine vision, not only maintaining the accuracy of detection and tracking, but even enabling more optimised ...
