Transdiagnostic patterns of electroencephalography (EEG)‐derived aperiodic activity across schizophrenia‐spectrum, bipolar, and depressive disorders: A systematic review

Psychiatry and Clinical Neurosciences, EarlyView.
Aperiodic electroencephalographic activity is proposed as a scalable marker of cortical population dynamics relevant to excitation–inhibition balance. However, it remains unclear whether aperiodic parameters represent disorder‐specific abnormalities or context‐sensitive indices of clinically relevant brain states.

Using fractal dimensions for characterizing intra-urban diversity. The example of Brussels [PDF]

The objective of this paper is to compare fractal-based parameters calculated by different fractal methods for urban built-up areas, and to link the observed spatial variations to variables commonly used in urban geography, urban economics or land use ...

THE RANDOM ITERATION ALGORITHM [PDF]

In the last decades, many researchers concerned their attention on fractals properties of objects. Fractals can be use to describe natural shapes so their applications are various in many fields such as informatics, economics, engineering, medical ...

β-catenin-α-catenin and actomyosin signaling differentially regulate growth cone contours and axon undulation and branching of retinal ganglion cells in situ

Frontiers in Cellular Neuroscience
IntroductionCadherin adhesive and actomyosin signaling are key cytomechanical cues required for neuronal circuit formation, but whether they function together to sculpt developing neurons is not known. Previously, we demonstrated that a β-catenin mutant (

Symptom‐Based Machine Learning Framework for Early Syndrome Coronavirus 2 (SARS‐CoV‐2) Infection Prediction

Applied AI Letters, Volume 8, Issue 1, February 2027.
This graphical abstract illustrates a symptom‐based machine learning framework for early prediction of SARS‐CoV‐2 infection. Clinical inputs such as SpO2, fever, cough, fatigue, and comorbidities are collected and preprocessed, followed by feature selection using a random forest‐based recursive elimination method.

An Explainable Self‐Supervised Temporal Transformer for Participant‐Level Classification of Depressive Symptoms From Resting‐State EEG

International Journal of Methods in Psychiatric Research, Volume 35, Issue 4, December 2026.
ABSTRACT Background Resting‐state electroencephalography (EEG) has emerged as a promising non‐invasive modality for investigating depressive symptoms; however, conventional deep‐learning methods often require large labeled datasets and provide limited interpretability.

Identifying Cardiovascular Risk by Nonlinear Heart Rate Dynamics Analysis: Translational Biomarker from Mice to Humans

Brain Sciences
Background: The beat-by-beat fluctuation of heart rate (HR) in its temporal sequence (HR dynamics) provides information on HR regulation by the autonomic nervous system (ANS) and its dysregulation in pathological states.

Fractal and nonfractal behavior in Levy flights

, 1987
The d‐dimentional space‐continuous time‐discrete Markovian random walk with a distribution of step lengths, which behaves like x−(α+d) with α>0 for large x, is studied. By studying the density–density correlation function of these walks, it is determined

Seed Storage Conditions for Zostera muelleri Restoration: Effects of Temperature, Salinity and Sterilisation on Seed Contamination, Viability and Seedling Emergence

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
The decline of seagrass meadows is a continuing global concern, and seed‐based restoration provides a scalable approach to recovering lost and degraded meadows. Such approaches require large quantities of seed to be collected, processed, and often stored for months until deployment.
