DOI: 10.1001/jamaophthalmol.2024.4856

Abstract: Importance Early detection of glaucoma is essential to timely monitoring and treatment, and primary open-angle glaucoma risk can be assessed by measuring intraocular pressure (IOP) or optic nerve head vertical cup-disc ratio (VCDR). Polygenic risk… read more here.

DOI: 10.1002/ajb2.16083

Abstract: PREMISE The evolutionary response of a trait to environmental change depends upon the level of additive genetic variance. It has been long argued that sustained selection will tend to deplete additive genetic variance as favoured… read more here.

recommendations! Published in 2021 at "Asian Journal of Control"

DOI: 10.1002/asjc.2581

Abstract: This paper is concerned with the mobile robot localization problem subject to filter gain uncertainty under dynamic event‐triggered communication mechanism, and meanwhile, the H∞ filtering performance and the error variance constraint are guaranteed. For saving… read more here.

DOI: 10.1002/asjc.3775

Abstract: The distributed optimization to minimize a smooth and strongly convex function is considered, in which the function can be described as the finite sum of all local objective functions over directed networks. A variance‐reduced distributed… read more here.

DOI: 10.1002/berj.3294

Abstract: Student satisfaction has received growing attention in Higher Education systems in recent years, and are increasingly used for internal and external accountability in the sector. This does leave us with questions on the extent to… read more here.

DOI: 10.1002/cem.3029

Abstract: In this study, 2 different methods for determining strictly conservative confidence intervals for expected values in the case of heteroscedastic errors are presented. A conservative confidence interval means that a given false positive error rate… read more here.

recommendations! Published in 2025 at "International Journal for Numerical Methods in Biomedical Engineering"

DOI: 10.1002/cnm.70040

Abstract: The purpose of this study is to address the lack of uncertainty quantification in numerical hemolysis models, which are critical for medical device evaluations. Specifically, we aim to develop a probabilistic hemolysis model, which incorporates… read more here.

recommendations! Published in 2018 at "Ecosphere"

DOI: 10.1002/ecs2.2343

Abstract: The emergence of large-scale fire classifications and products informed by remote sensing data has enabled opportunities to include variability or heterogeneity as part of modern fire regime classifications. Currently, basic fire metrics such as mean… read more here.

recommendations! Published in 2017 at "Journal of Forecasting"

DOI: 10.1002/for.2465

Abstract: Suppose Zt is the square of a time series Yt whose conditional mean is zero. We do not specify a model for Yt, but assume that there exists a p×1 parameter vector Φ such that… read more here.

recommendations! Published in 2017 at "Human Brain Mapping"

DOI: 10.1002/hbm.23764

Abstract: Autism spectrum disorder (ASD) is a neurodevelopmental condition associated with altered brain connectivity. Previous neuroimaging research demonstrates inconsistent results, particularly in studies of functional connectivity in ASD. Typically, these inconsistent findings are results of studies… read more here.

Post‐stroke cognitive deficits rarely come alone: Handling co‐morbidity in lesion‐behaviour mapping

Sign Up to like & get
recommendations! Published in 2019 at "Human Brain Mapping"

DOI: 10.1002/hbm.24885

Abstract: Post‐stroke behavioural symptoms often correlate and systematically co‐occur with each other, either because they share cognitive processes, or because their neural correlates are often damaged together. Thus, neuropsychological symptoms often share variance. Many previous lesion‐behaviour… read more here.
