Fast Rate Estimation for RDO Mode Decision in HEVC

open access: yesEntropy, 2014
The latter-day H.265/HEVC video compression standard is able to provide two-times higher compression efficiency compared to the current industrial standard, H.264/AVC. However, coding complexity also increased.

Weight enumerators of Reed-Muller codes from cubic curves and their duals

open access: yes, 2018
Let $\mathbb{F}_q$ be a finite field of characteristic not equal to $2$ or $3$. We compute the weight enumerators of some projective and affine Reed-Muller codes of order $3$ over $\mathbb{F}_q$.

Context-based adaptive arithmetic coding in time and frequency domain for the lossless compression of audio coding parameters at variable rate

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2013
This paper presents a novel lossless compression technique of the context-based adaptive arithmetic coding which can be used to further compress the quantized parameters in audio codec.

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Overlapped Arithmetic Codes

open access: yesCoRR
Arithmetic codes are usually deemed as the most important means to implement lossless source coding, whose principle is mapping every source symbol to a sub-interval in [0, 1). For every source symbol, the length of its mapping sub-interval is exactly equal to its probability.

Digital Transformation and Informal Innovation in Africa: Reframing STI Policy for Inclusive Circular Economy Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid increasing environmental and economic pressures, Africa's transition to a circular economy (CE) presents a vital pathway to inclusive, low‐carbon development. Yet, how digital transformation, informal innovation, and science, technology, and innovation (STI) policy readiness shape CE outcomes remains underexplored.
