Automatic Identification of Twin Zygosity in Resting-State Functional MRI [PDF]

arXiv, 2018
A key strength of twin studies arises from the fact that there are two types of twins, monozygotic and dizygotic, that share differing amounts of genetic information. Accurate differentiation of twin types allows efficient inference on genetic influences in a population. However, identification of zygosity is often prone to errors without genotying. In

Functional Connectome Fingerprint Gradients in Young Adults [PDF]

arXiv, 2020
The assessment of brain fingerprints has emerged in the recent years as an important tool to study individual differences and to infer quality of neuroimaging datasets. Studies so far have mainly focused on connectivity fingerprints between different brain scans of the same individual.

Demonstration of a Standalone, Descriptive, and Predictive Digital Twin of a Floating Offshore Wind Turbine [PDF]

arXiv, 2023
Digital Twins bring several benefits for planning, operation, and maintenance of remote offshore assets. In this work, we explain the digital twin concept and the capability level scale in the context of wind energy. Furthermore, we demonstrate a standalone digital twin, a descriptive digital twin, and a prescriptive digital twin of an operational ...

Isolated imperforate anus in dizygotic twins

Journal of Pediatric Surgery Case Reports, 2023
The authors report an isolated imperforate anus case in a dizygotic twin, which is the first reported case in the literature, the other reported cases were in monozygotic twins.

Identical twins carry a persistent epigenetic signature of early genome programming

Nature Communications, 2021
The mechanisms underlying how monozygotic (or identical) twins arise are yet to be determined. Here, the authors investigate this in an epigenome-wide association study, showing that monozygotic twinning has a characteristic DNA methylation signature in ...

Gender differences in like-sex middle-aged twins: an extended network analysis of depressive symptoms, cognitive functions and leisure activities

European Psychiatry
Background Depression affects twice as many women as men. Risk factors for depression certainly impact this difference, but their strong interconnectedness challenges the assessment of standalone contributions.

Protocol for an Observational Study on the Effects of Early-Life Participation in Contact Sports on Later-Life Cognition in a Sample of Monozygotic and Dizygotic Swedish Twins Reared Together and Twins Reared Apart [PDF]

arXiv, 2018
A large body of work links traumatic brain injury (TBI) in adulthood to the onset of Alzheimer's disease (AD). AD is the chief cause of dementia, leading to reduced cognitive capacity and autonomy and increased mortality risk. More recently, researchers have sought to investigate whether TBI experienced in early-life may influence trajectories of ...

Digital Twins Are Not Monozygotic -- Cross-Replicating ADAS Testing in Two Industry-Grade Automotive Simulators [PDF]

arXiv, 2020
The increasing levels of software- and data-intensive driving automation call for an evolution of automotive software testing. As a recommended practice of the Verification and Validation (V&V) process of ISO/PAS 21448, a candidate standard for safety of the intended functionality for road vehicles, simulation-based testing has the potential to reduce ...

Advancements in multiple sclerosis

Internal Medicine Journal, EarlyView.
Abstract The global prevalence of multiple sclerosis (MS) is increasing, and early diagnosis and treatment is essential in mitigating disability. While recent therapeutic advancements have significantly reduced relapse rates, the progressive and degenerative aspects of MS continue to pose major challenges.
