Advanced Science, EarlyView.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 simple lossy audio coding scheme based on the DWT [PDF]
, 2007 This paper proposes a simple scheme for audio coding that does not use perceptual models. The audio coder is based on the discrete wavelet transform to decorrelate signals, computed through the lifting scheme, and followed by Huffman coding.

A quasi-orthogonal, invertible, and perceptually relevant time-frequency transform for audio coding
, 2015 International audienceWe describe ERB-MDCT, an invertible real-valued time-frequency transform based on MDCT, which is widely used in audio coding (e.g. MP3 and AAC).

Perceptual Coding of Audio Signals Using Adaptive Time-Frequency Transform
EURASIP Journal on Audio, Speech, and Music Processing, 2007 Wide band digital audio signals have a very high data-rate associated with them due to their complex nature and demand for high-quality reproduction.

Magnetic Flux Guides by Material Extrusion
Advanced Science, EarlyView.Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Three-channel dependent mid/side coding framwork for multichannel 3D audio
Tongxin xuebao, 2014 The conventional mid/side coding method is discussed and generalized to a three-channel dependent M/S cod-ing (3D-M/S) method. Moreover, a codec framework based on 3D-M/S is proposed which enables the 3D-M/S to work for three-dimensional audio systems ...
