Fast, automated optimization of virtual monoenergetic images with the dual‐energy image synthesizer for cone‐beam CT

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Dual‐energy cone‐beam CT (DE‐CBCT) has become subject of recent interest due to the ability to produce virtual monoenergetic images (VMIs) with improved soft‐tissue contrast and reduced nonuniformity artifacts. However, efficient production and optimization of VMIs remains an under‐explored part of DE‐CBCT's application.

The burden of intracranial atherosclerosis on cerebral small vessel disease: A community cohort study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Exploring the prevalence and association between intracranial atherosclerosis (ICAS) and cerebral small vessel diseases (CSVD), this study delved beyond the current scope, utilising high‐resolution vessel wall MRI (HRVW‐MRI) to investigate how subtle changes in intracranial atherosclerotic features influence the various burdens of ...

The Influence of Social and Environmental Labels on Purchasing: An Information and Systematic-heuristic Processing Approach

open access: yesInnovar: Revista de Ciencias Administrativas y Sociales, 2015
This paper aims at exploring how social and environmental (SE) labels influence purchasing. By drawing on the information processing and the systematic-heuristic models, this study tests the process followed by consumers when purchasing SE labeled ...

Two-stage building energy consumption clustering based on temporal and peak demand patterns [PDF]

open access: yesarXiv, 2020
Analyzing smart meter data to understand energy consumption patterns helps utilities and energy providers perform customized demand response operations. Existing energy consumption segmentation techniques use assumptions that could result in reduced quality of clusters in representing their members. We address this limitation by introducing a two-stage

Stability of a Stochastic Model for Demand-Response [PDF]

open access: yes, 2010
We study the stability of a Markovian model of electricity production and consumption that incorporates production volatility due to renewables and uncertainty about actual demand versus planned production. We assume that the energy producer targets a fixed energy reserve, subject to ramp-up and ramp-down constraints, and that appliances are subject to

Associations of Cerebrospinal Fluid Orexin‐A, Alzheimer Disease Biomarkers, and Cognitive Performance

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACTObjectiveCerebrospinal fluid (CSF) orexin‐A has been suggested to be a biomarker of Alzheimer disease (AD). In both cognitively unimpaired healthy older adults and individuals with symptomatic AD, CSF orexin‐A is positively associated with CSF Aβ42, p‐tau181, and total tau (t‐tau) concentrations.

Unleashing the Power of Multiomics: Unraveling the Molecular Landscape of Peripheral Neuropathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Peripheral neuropathies (PNs) affect over 20 million individuals in the United States, manifesting as a wide range of sensory, motor, and autonomic nerve symptoms. While various conditions such as diabetes, metabolic disorders, trauma, autoimmune disease, and chemotherapy‐induced neurotoxicity have been linked to PN, approximately one‐third of

Diagnostic Challenge in Frontal Variant Alzheimer's Disease With Low Amyloid‐β PET Retention

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diagnosing frontal variant Alzheimer's disease (fvAD) is difficult and could be even more difficult when amyloid‐beta (Aβ) PET retention is low. A 63‐year‐old woman presenting with a 3‐year history of apathy and memory impairment showed executive dysfunction, memory impairment, and severe bilateral frontotemporal atrophy on MRI.
