Article Abstract

The study of complex behavior of biological systems has become increasingly dependent on evolutionary network modeling. In particular, multi-omics networks capture interactions between biomolecules such as proteins and metabolites, providing a basis for predicting relationships between such biomolecules and various phenotypic traits of complex diseases. In this paper, we introduce an integrative framework that given a multi-omics network representing a cohort of subjects, learns expressive representations for network nodes, and combines the learned nodes representations with the biological profiles of individual subjects for enriched representation of the subjects. With extensive empirical evaluation using real-world multi-omics networks, we show that our proposed framework significantly outperforms existing and baseline methods in terms of subject representation accuracy, particularly when the multi-omics network representing the cohort is sparse and structured and therefore, more informative.

Overcoming gaps and barriers to effectively integrate social science in European conservation.

Conserv Biol

September 2025

Alfred Toepfer Academy for Nature Conservation, Schneverdingen, Germany.

The importance of social science to address the human dimensions of natural resource management is increasingly recognized in the conservation field, yet the application of associated concepts, theories, methods, and data remains underrepresented in parts of Europe. Common barriers and gaps, persistent over decades, including institutional constraints, work environment, different cultures and languages between natural and social science disciplines, lack of qualified personnel, and an accessible professional community, are often cited as underlying and driving factors. To better understand, contextualize, and inform solutions for wider use of social science, we analyzed interactions with conservation researchers and practitioners across a series of organized events from 2018 to 2023 (e.

Introduction: Efforts to strengthen healthcare systems have led to the development of clinical practice guidance, defined as clinical decision-making aids built on scientific evidence, experiential knowledge, and ideally, patient values. This review evaluates the accessibility, relevance, and quality of existing trauma guidance globally.

Methods: A systematic review evaluated trauma-related clinical guidance sources published from 2016 to 2023, searching in English across eight databases and 28 professional society websites.

Background: Family climate substantially influences children’s socio-emotional development. We examined mothers’ mental representations of their children and their relationships in three groups of mothers with young children (0–6 years): mothers (1) with a borderline personality disorder (BPD) (2), with a depressive or anxiety disorder but no BPD (AD/D), or (3) without a current mental disorder (CON). We expected both clinical groups to show more negative mental representations – more expressed emotion reflecting a critical attitude toward the child in general, more hostile attributions to child misbehavior in particular, and a less balanced view of the child (i.

Despite the functional specialization in visual cortex, there is growing evidence that the processing of chromatic and spatial visual features is intertwined. While past studies focused on visual field biases in retina and behavior, large-scale dependencies between coding of color and retinotopic space are largely unexplored in the cortex. Using a sample of male and female volunteers, we asked whether spatial color biases are shared across different human observers, and whether they are idiosyncratic for distinct areas.

Background: Emotion recognition from electroencephalography (EEG) can play a pivotal role in the advancement of brain-computer interfaces (BCIs). Recent developments in deep learning, particularly convolutional neural networks (CNNs) and hybrid models, have significantly enhanced interest in this field. However, standard convolutional layers often conflate characteristics across various brain rhythms, complicating the identification of distinctive features vital for emotion recognition.
