Broad boron sheets and boron nanotubes: An ab initio study of structural, electronic, and mechanical properties

, 2006
Based on a numerical ab initio study, we discuss a structure model for a broad boron sheet, which is the analog of a single graphite sheet, and the precursor of boron nanotubes.

Antecedents of burnout among elite dancers: a longitudinal test of basic needs theory [PDF]

, 2011
Objectives: Little is known regarding the social-psychological predictors of burnout in the dance domain. Drawing from basic needs theory, a sub-theory in the self-determination theory framework (Deci & Ryan, 2000), this study examined whether changes in

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

ESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

The Role of Magnetic Resonance Spectroscopy (MRS), Diffusion‐Tensor‐Imaging (DTI) and Structural MRI in the Alzheimer's Disease and Mild Cognitive Impairment Diagnosis: A Review

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Alzheimer's disease (AD) is one of the most common neurological disorders affecting older adults, with approximately 7.2 million cases only in the United States. This number is projected to increase to 13.8 million in the United States by 2060, leading to increased expenditures for healthcare, long‐term care and hospice services. Consequently,

Levels of high-sensitive troponin T and mid-regional pro-adrenomedullin after COVID-19 vaccination in vulnerable groups: monitoring cardiovascular safety of COVID-19 vaccination

Frontiers in Cardiovascular Medicine
BackgroundCOVID-19 vaccines are well tolerated and effective but may have adverse effects on the cardiovascular system. Vaccine-associated myocardial injury was analysed by measuring high-sensitive troponin T (hsTnT); mid-regional pro-adrenomedullin (MR ...

Phenomenology of the Higgs sector of a Dimension-7 Neutrino Mass Generation Mechanism

, 2018
In this paper, we revisit the dimension-7 neutrino mass generation mechanism based on the addition of an isospin $3/2$ scalar quadruplet and two vector-like iso-triplet leptons to the standard model.

Animal fluency in people with Parkinson's disease: Item‐based performance before and after deep brain stimulation surgery

Journal of Neuropsychology, EarlyView.
Abstract People with Parkinson disease (PD) after surgery for deep brain stimulation (DBS) of the subthalamic nucleus (STN‐DBS) often decline in animal fluency due to impairments in executive functions and/or language. Item‐based measures of animal fluency may shed light on the specific nature of this decline, and into the strategies used when ...
