The Build-Up Construction for Codes over a Commutative Non-Unitary Ring of Order 9

open access: yesMathematics
The build-up method is a powerful class of propagation rules that generate self-dual codes over finite fields and unitary rings. Recently, it was extended to non-unitary rings of order 4, to generate quasi self-dual codes.

The Lie group Euler methods of multibody system dynamics with holonomic constraints

open access: yesAdvances in Mechanical Engineering, 2018
The Euler methods on Lie group are developed for the differential–algebraic equations of multibody system dynamics with holonomic constraints. The implicit Euler method is used to solve the differential–algebraic equations as Euler–Lagrange equations on ...

A compatibility criterion for optimal control and information aggregation in hierarchical network systems

open access: yesAsian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

The Mass Formula for Self-Orthogonal and Self-Dual Codes over a Non-Unitary Non-Commutative Ring

open access: yesMathematics
In this paper, we derive a mass formula for the self-orthogonal codes and self-dual codes over a non-commutative non-unitary ring, namely, Ep=a,b|pa=pb=0,a2=a,b2=b,ab=a,ba=b, where a≠b and p is any odd prime.

Young people's occupational aspirations beyond the aspiration discourse: A sociocultural perspective

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Young people's aspirations have been the focus of many educational, sociological and psychological studies. This paper argues, firstly, that the concept of aspirations holds greater generative potential than suggested by the policy‐oriented ‘aspiration discourse’.

Improving the learning experience in an undergraduate course on microbial metabolism by using an illustrated story

open access: yesBiochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 131-141, March/April 2025.
Abstract In the classroom, metabolism is often approached and received as a mundane exercise in memorization. Teaching metabolism also faces the challenge of negative perceptions that can impede learning. We sought to improve the learning experience in an undergraduate lecture course on microbial metabolism by implementing an illustrated story that ...

Housing Warmth/Coolness and Quietness Correlate With Whole‐Brain Fractional Anisotropy in Healthy Adults

open access: yesBrain Health, EarlyView.
ABSTRACT Introduction Residential environments have been linked to brain structure, particularly in children, older adults, and clinical populations. However, little is known about how different dimensions of the housing environment relate to brain white matter microstructure in healthy adults, or whether specific environmental factors show stronger ...

Eco‐Innovation, Economic Complexity, and Sustainability: A Bibliometric and Systematic Literature Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study systematizes the literature on eco‐innovation and economic complexity, aiming to understand how the sophistication of productive structures shapes countries' capacity to develop environmentally responsible innovations, and how eco‐innovation may, in turn, influence productive sophistication.

Amenability and coamenability of algebraic quantum groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We define concepts of amenability and coamenability for algebraic quantum groups in the sense of Van Daele (1998). We show that coamenability of an algebraic quantum group always implies amenability of its dual.
