Objective: Many neural systems display spontaneous, spatiotemporal patterns of neural activity that are crucial for information processing. While these cascading patterns presumably arise from the underlying network of synaptic connections between neurons, the precise contribution of the network's local and global connectivity to these patterns and information processing remains largely unknown.
Approach: Here, we demonstrate how network structure supports information processing through network dynamics in empirical and simulated spiking neurons using mathematical tools from linear systems theory, network control theory, and information theory.
Main Results: In particular, we show that activity, and the information that it contains, travels through cycles in real and simulated networks.
Significance: Broadly, our results demonstrate how cascading neural networks could contribute to cognitive faculties that require lasting activation of neuronal patterns, such as working memory or attention.

PHIStruct: Improving phage-host interaction prediction at low sequence similarity settings using structure-aware protein embeddings.
Bioinformatics
January 2025
Bioinformatics Lab, Advanced Research Institute for Informatics, Computing and Networking, De La Salle University, Manila, 1004, Philippines.
Motivation: Recent computational approaches for predicting phage-host interaction have explored the use of sequence-only protein language models to produce embeddings of phage proteins without manual feature engineering. However, these embeddings do not directly capture protein structure information and structure-informed signals related to host specificity.
Results: We present PHIStruct, a multilayer perceptron that takes in structure-aware embeddings of receptor-binding proteins, generated via the structure-aware protein language model SaProt, and then predicts the host from among the ESKAPEE genera.
Chemotherapy-Related Cognitive Impairment and Changes in Neural Network Dynamics: A Systematic Review.
Neurology
January 2025
Department of Neurosurgery, Lenox Hill Hospital, Zucker School of Medicine at Hofstra/Northwell, New York, NY; and.
Background And Objectives: This systematic review aims to synthesize the current literature on the association between chemotherapy (CTX) and chemotherapy-related cognitive impairment (CRCI) with functional and structural brain alterations in patients with noncentral nervous system cancers.
Methods: A comprehensive search of the PubMed/MEDLINE, Web of Science, and Embase databases was conducted, and results were reported following preferred reporting items for systematic review and meta-analyses guidelines. Data on study design, comparison cohort characteristics, patient demographics, cancer type, CTX agents, neuroimaging methods, structural and functional connectivity (FC) changes, and cognitive/psychological assessments in adult patients were extracted and reported.
The structure and motivational significance of early beliefs about ability.
Dev Psychol
January 2025
Department of Psychology, New York University.
Adults hold a broad range of beliefs about intellectual ability. Key examples include beliefs about its malleability, its distribution in the population, whether high levels of it ("brilliance") are necessary for success, its origins, and its responsiveness to intervention. Here, we examined the structure and motivational significance of this network of consequential beliefs in a sample of elementary school-age children (5- to 11-year-olds, = 231; 116 girls, 112 boys, three gender nonbinary children; predominantly White and Asian children from relatively high-income backgrounds).

During the last decades, the use of innovative hybrid materials in energy storage devices has led to notable advances in the field. However, further enhancement of their electrochemical performance faces significant challenges nowadays, imposed by the materials used in the electrodes and the electrolyte. Such problems include the high solubility of both the organic and the inorganic anode components in the electrolyte as well as the limited intrinsic electronic conductivity and substantial volume variation of the materials during cycling.

Department of Quality, Safety and Clinical Adoption, University Health Network, Toronto, Canada.
Purpose: Despite robust quality improvement efforts in healthcare, learning from patient safety incidents remains difficult. Our study explores counter-vailing powers shaping learning processes and possibilities in healthcare organizations, with a focus on social, political and organizational dynamics of learning.
Design/methodology/approach: Deploying concepts of situated curriculum, boundary work and interconnected knowledge practices, we interviewed staff and physicians ( = 15) in a large Academic Health Science Centre in Canada about their experiences of incident investigations and resultant information sharing.
