Biosystems. 2024 Jan 2;235:105110. doi: 10.1016/j.biosystems.2023.105110. Online ahead of print.ABSTRACTIn this paper, we examine how deep learning can be utilized to investigate neural health and the difficulties in interpreting neurological analyses within algorithmic models. The key contribution of this paper is the investigation of the impact of a dead neuron on the performance of artificial neural networks (ANNs). Therefore, we conduct several tests using different training algorithms and activation functions to identify the precise influence of the training process on neighboring neurons and the overall performance o...

Homeostasis and information processing: The key frames for the thermodynamics of biological systems
Biosystems. 2023 Dec 30:105115. doi: 10.1016/j.biosystems.2023.105115. Online ahead of print.ABSTRACTLife is a natural phenomenon ineluctably subject to the laws and principles of physics. In this framework, thermodynamics has a crucial role, since living beings are structured on a molecular and cellular basis that can only be maintained with extensive energy consumption. This imposes that living beings are necessarily open systems. But the survival of each type of organism depends on the relative stability of certain essential variables, even in the presence of the disturbances to which they are subjected. The stability o...

A method for the systematic selection of enzyme panel candidates by solving the maximum diversity problem
We present a novel algorithm for the automatic selection of subsets from enzyme families. A tabu search algorithm solving the maximum diversity problem for sequence identity was designed and implemented, and applied to three diverse enzyme families. We show that this approach automatically selects panels of enzymes that contain high richness and relative abundance of the known catalytic functions, and outperforms other methods such as k-medoids.PMID:38160995 | DOI:10.1016/j.biosystems.2023.105105 (Source: Biosystems)

Dynamics, synchronization and traveling wave patterns of flux coupled network of Chay neurons
Biosystems. 2023 Dec 28:105113. doi: 10.1016/j.biosystems.2023.105113. Online ahead of print.ABSTRACTStudies in the literature have demonstrated the significance of the synchronization of neuronal electrical activity for signal transmission and information encoding. In light of this importance, we investigate the synchronization of the Chay neuron model using both theoretical analysis and numerical simulations. The Chay model is chosen for its comprehensive understanding of neuronal behavior and computational efficiency. Additionally, we explore the impact of electromagnetic induction, leading to the magnetic flux Chay neu...

Continuity and discontinuity in evolutionary processes with emphasis on plants
Biosystems. 2023 Dec 28:105108. doi: 10.1016/j.biosystems.2023.105108. Online ahead of print.ABSTRACTThe present work is aimed to review the concepts of continuity and discontinuity in the reproductive processes and their impact on the evolutionary outcome, emphasizing on the plant model. Let be stated that evolutionary changes need to pass down generation after generation through the cellular reproductive mechanisms, and these mechanisms can account for changes from single nucleotide to genome-wide mutations. Patterns of continuity and discontinuity in sexual and asexual species pose notorious differences as the involveme...

Principles of cognitive biology and the concept of biocivilisations
Biosystems. 2023 Dec 27:105109. doi: 10.1016/j.biosystems.2023.105109. Online ahead of print.ABSTRACTA range of studies published in the last few decades promotes the cognitive aspects of life: all organisms, from bacteria to mammals, are capable of sensing/perception, decision-making, problem-solving, learning, and other cognitive functions, including sentience and consciousness. In this paper I present a scientific and philosophical synthesis of these studies, leading to an integrated view of cognitive biology. This view is expressed through the four principles applicable to all living systems: (1) sentience and consciou...

Artificial Neuronal Networks (ANNs) can provide valuable insights into the brain dynamics of humans and animals. We built a simple and fast shallow ANN-based solution for sleep recognition in EEGs recorded in freely moving rats. The ANN was constructed using open-source software and truncated to one formula with empirically defined weight coefficients. The optimization of the ANN model's performance (i.e., post-processing) relied on a proba...
