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 ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Research of Hamming weight-based algebraic side-channel attack on LED

open access: yesTongxin xuebao, 2013
:The security of LED against the algebraic side-channel attack (ASCA)was evaluated, which is a lightweight block cipher proposed in CHES 2011.Firstly, the attack model of ASCA was analyzed, and then the design and algebraic representations of LED were ...

Discrimination in a General Algebraic Setting

open access: yesThe Scientific World Journal, 2015
Discriminating groups were introduced by G. Baumslag, A. Myasnikov, and V. Remeslennikov as an outgrowth of their theory of algebraic geometry over groups.

Examining the Directional Effects of Insomnia, Anxiety, and Depression Symptoms: Results From a Longitudinal Study Conducted During the COVID‐19 Pandemic

open access: yesJournal of Clinical Psychology, EarlyView.
ABSTRACT Objectives While some research suggests that increases in anxiety symptoms drive changes in insomnia and depression symptoms, other studies support that these relations may be bidirectional. The present study therefore aimed to further examine how anxiety, insomnia and depression symptoms predict changes in these symptoms over time.

An Improved Algebraic Attack on Hamsi-256 [PDF]

open access: yes, 2011
Hamsi is one of the 14 second-stage candidates in NIST's SHA-3 competition. The only previous attack on this hash function was a very marginal attack on its 256-bit version published by Thomas Fuhr at Asiacrypt 2010, which is better than generic attacks only for very short messages of fewer than 100 32-bit blocks, and is only 26 times faster than a ...

Theory of Supercritical Coupling and Generalized Bound States in the Continuum

open access: yesLaser &Photonics Reviews, EarlyView.
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

Analysis of the success probability of cube attack

open access: yesTongxin xuebao, 2012
The success probability of cube attack was theoretically discussed when a boolean function was chosen at random and the algebraic degree or the number of terms in its algebraic normal form representation was restricted.The results provided theoretic ...

Algebraic adversarial attacks on explainability models

open access: yesMachine Learning: Engineering
Classical adversarial attacks are phrased as a constrained optimisation problem. Despite the efficacy of a constrained optimisation approach to adversarial attacks, one cannot trace how an adversarial point was generated. In this work, we propose an algebraic approach to adversarial attacks and study the conditions under which one can generate ...
