Wave propagation in a light-temperature neural network under adaptive local energy balance
External electric and mechanical stimuli can induce shape deformation in excitable media because of its intrinsic flexible property. When the signals propagation in the media is described by a neural network, ...

Open AccessAssessment of bone tissue cytoarchitectonics by 2D 1H NMR relaxometry maps
Bone is a complex tissue that fulfills the role of a resistance structure. This quality is most commonly assessed by bone densitometry, but bone strength may not only be related to bone mineral density but als...

Magnetite in the abdomen and antennae of Apis mellifera honeybees
The detection of magnetic fields by animals is known as magnetoreception. The ferromagnetic hypothesis explains magnetoreception assuming that magnetic nanoparticles are used as magnetic field transducers. Mag...

Automatic classification of seizure and seizure-free EEG signals based on phase space reconstruction features
Epilepsy is a type of brain disorder triggered by an abrupt electrical imbalance of neuronal networks. An electroencephalogram (EEG) is a diagnostic tool to capture the underlying brain mechanisms and detect s...

Regulatory disturbances in the dynamical signaling systems of \(Ca^{2+}\) and NO in fibroblasts cause fibrotic disorders
Studying the calcium dynamics within a fibroblast cell individually has provided only a restricted understanding of its functions. However, research efforts focusing on systems biology approaches for such inve...

Roles of astrocytes and prions in Alzheimer’s disease: insights from mathematical modeling
We present a mathematical model that explores the progression of Alzheimer’s disease, with a particular focus on the involvement of disease-related proteins and astrocytes. Our model consists of a coupled syst...

Mathematical modeling of viral infection and the immune response controlled by the circadian clock
Time of day affects how well the immune system responds to viral or bacterial infections. While it is well known that the immune system is regulated by the circadian clock, the dynamic origin of time-of-day-de...

Open AccessMicrorheological comparison of melanoma cells by atomic force microscopy
Melanoma is one of the most severe cancers due to its great potential to form metastasis. Recent studies showed the importance of mechanical property assessment in metastasis formation which depends on the cyt...

Similarity analysis of bioconvection of unsteady nonhomogeneous hybrid nanofluids influenced by motile microorganisms
Motile bacteria in hybrid nanofluids cause bioconvection. Bacillus cereus, Pseudomonas viscosa, Bacillus brevis, Salmonella typhimurium, and Pseudomonas fluorescens were used to evaluate their effect and dispersi...

Base flip** mechanism and binding strength of methyl-damaged DNA during the interaction with AGT
Methyl damage to DNA bases is common in the cell nucleus. O6-alkylguanine-DNA alkyl transferase (AGT) may be a promising candidate for direct damage reversal in methylated DNA (mDNA) at the O6 point of the gua...

Generic algebraic conditions for the occurrence of switch-like behavior of a chemical kinetic system of the hypoxia pathway
Weakly reversible chemical reaction networks with zero deficiency associated with mass-action kinetics admit, within each positive stoichiometric compatibility class, one positive steady state which is locally...

High order sliding mode control for restoration of a population of predators in a Lotka-Volterra system
Human-induced extinction and rapid ecological changes require the development of techniques that can help avoid extinction of endangered species. The most used strategy to avoid extinction is reintroduction of...

Suppression of beta oscillations by delayed feedback in a cortex-basal ganglia-thalamus-pedunculopontine nucleus neural loop model
Excessive neural synchronization of neural populations in the beta (β) frequency range (12–35 Hz) is intimately related to the symptoms of hypokinesia in Parkinson’s disease (PD). Studies have shown that delayed ...

Impact of noise on the instability of spiral waves in stochastic 2D mathematical models of human atrial fibrillation
Sustained spiral waves, also known as rotors, are pivotal mechanisms in persistent atrial fibrillation (AF). Stochasticity is inevitable in nonlinear biological systems such as the heart; however, it is unclea...
