Primary open angle Glaucoma (POAG) is one of the most common causes of permanent blindness in the world. Recent studies have suggested the hypothesis that POAG is also a central nervous system disorder which may result in...

Understanding the role of Tau protein aggregation in the pathogenesis of Alzheimer's disease is critical for the development of new Tau-based therapeutic strategies to slow or prevent dementia. We tested the hypothesis that Tau...

Fixed-Parameter Tractable Distances to Sparse Graph Classes
We show that for various classes $\mathcal{C}$ of sparse graphs, and several measures of distance to such classes (such as edit distance and elimination distance), the problem of determining the distance of a given graph...
Positive Influence Dominating Set Generation via a New Greedy Algorithm
Matthew Rink
Jan 01, 0001
Current algorithms in the Positive Influence Dominating Set (PIDS) problem domain are focused on a specific type of PIDS, the Total Positive Influence Dominating Set (TPIDS). We have developed an algorithm specifically targeted...

Structural Covariance Networks in Children with Autism or ADHD
While autism and attention-deficit/hyperactivity disorder (ADHD) are considered distinct conditions from a diagnostic perspective, clinically they share some phenotypic features and have high comorbidity. Regardless, most...
Brain network disintegration during sedation is mediated by the complexity of sparsely connected regions.
The precise mechanism of anaesthetic action on a neural level remains unclear. Recent approaches suggest that anaesthetics attenuate the complexity of interactions (connectivity) however evidence remains insufficient. We used...

Involvement of the reward network is associated with apathy in cerebral small vessel disease.
Danuta M Lisiecka-Ford, Daniel J Tozer, Robin G Morris, Andrew J Lawrence, Thomas R Barrick, Hugh S Markus
May 01, 2018
INTRODUCTION: Apathy is a common yet under-recognised feature of cerebral small vessel disease (SVD), but its underlying neurobiological basis is not yet understood. We hypothesized that damage to the reward network is...

The functional significance of resting state networks and their abnormal manifestations in psychiatric disorders are firmly established, as is the importance of the cortical rhythms in mediating these networks. Resting state...

Order picking in parallel-aisle warehouses with multiple blocks:
In this paper, we consider the order picking problem (OPP), which constitutes one of the special cases of the Steiner travelling salesperson problem and addresses the costliest operation in a warehouse. Given a list of items to...

Transdiagnostic Brain Mapping in Developmental Disorders.
Childhood learning difficulties and developmental disorders are common, but progress toward understanding their underlying brain mechanisms has been slow. Structural neuroimaging, cognitive, and learning data were collected from...

Autistic traits, resting-state connectivity, and absolute pitch in professional musicians
BACKGROUND: Recent studies indicate increased autistic traits in musicians with absolute pitch and a higher proportion of absolute pitch in people with autism. Theoretical accounts connect both of these with shared neural...
Scheme design considering network topology and multi-attribute decision-making for under frequency load shedding
Power system emergency control is one key defense strategy in contingencies for protecting the system from cascading blackout. Under Frequency Load Shedding (UFLS) is one such strategy to ensure system stability by shedding...
A Cross-Country Network Analysis of Resilience Systems in Young Adults.
Multisystemic resilience has been conceptualised as involving a constellation of protective factors which operate at different levels to promote adaptation and thriving despite experiences of adversity. We used network modelling...
Discrete Morse Functions, Vector Fields, and Homological Sequences on Trees
Ian B. Rand
Jan 01, 0001
The goal of this project is to construct a discrete Morse function which induces both a unique gradient vector field and homological sequence on a given tree. After reviewing the basics of discrete Morse theory, we will show...
