Depression Detection from Three-Channel Resting-State EEG Using a Hybrid Conv1D and Spectral–Statistical Fusion Model

open access: yesSensors
Major depressive disorder requires scalable, low-burden screening tools. We examined whether three-channel resting-state EEG can support reliable discrimination between major depressive disorder and healthy controls using a lightweight model compatible ...

Conceptual solution for enhancing the electrolyser power supply system and hydrogen production [PDF]

open access: yesZbornik Radova: Elektrotehnički Institut "Nikola Tesla"
The paper presents a realized solution for powering an alkaline electrolyser for hydrogen production and offers a proposal for its improvement. By connecting photovoltaic panels, via a DC-DC converter, directly to the DC side of the existing twelve-pulse

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Computational Analysis of EEG Responses to Anxiogenic Stimuli Using Machine Learning Algorithms

open access: yesApplied Sciences
Anxiety disorders are commonly assessed using instruments such as HAM-A and GAD-7. These tools rely on patient self-report and clinician interpretation, which may introduce variability.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
