Chemical hyperstructures for Astatine, Tellurium and for Bismuth
Bulletin of Computational Applied Mathematics, 2019 The concept of weak algebraic hyperstructures constitutes a generalization of the well-known algebraic hyperstructures. The aim of this paper is to present some of the results, methods and ideas about chemical examples of weak algebraic hyperstructures.

Asian 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.

Risk‐aware safe reinforcement learning for control of stochastic linear systems
Asian Journal of Control, EarlyView.Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Asian Journal of Control, EarlyView.Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Algorithms and methods in differential algebra
Theoretical Computer Science, 1996 The first three sections provide a rather superficial survey of Risch theory, i.e., solving \(y'=f\) by elementary functions, and symbolically solving linear \(n\)th order differential equations. The sections 4 and 5 give a survey of problems related to polynomial vector fields \(V=V_x\partial_x+V_y\partial_y+V_z\partial_z\), with \(V_x,V_y,V_z\in ...

On structural controllability in complex networks with periodic switching topologies
Asian Journal of Control, EarlyView.Abstract This paper investigates the structural controllability of complex networks with periodic switching topologies. First, several graph transformations that preserve structural controllability are demonstrated. Based on the n‐walk theory, a criterion is derived that determines structural controllability by analyzing only the joint graph within a ...

Biochemistry 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 ...

Specifying Hyperdocuments with Algebraic Methods
EPiC Series in Computing, 2018 Algebraic specification methods, well-known in the area of programming languages, are adapted to present a tailored framework for hyperdocuments and hyperdocument systems. In this framework, a hyperdocument is defined via its abstract syntax, which is a variable-free term of a suitable constructor-based signature.

Brain 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 ...
