Vitamin D is not associated with incident dementia or cognitive impairment: an 18-y follow-up study in community-living old men
Alzheimer disease cognitive impairment cohort dementia Mendelian randomization vascular dementia vitamin D 25-hydroxyvitamin D
2018/11/13
Background: Vitamin D has been implicated as being important for maintaining cognitive function in old age. Results from longitudinal studies examining the association of vitamin D with incident demen...
Association of dietary cholesterol and egg intakes with the risk of incident dementia or Alzheimer disease: the Kuopio Ischaemic Heart Disease Risk Factor Study
Alzheimer disease apolipoprotein E4 cholesterol cognitive function,
2018/11/12
Background: There is little information about the associations of intakes of cholesterol and eggs, a major source of dietary cholesterol, with the risk of cognitive decline in general populations or i...
Serum calcium and incident type 2 diabetes: the Atherosclerosis Risk in Communities (ARIC) study
calcium-sensing receptor polymorphism cohort study diabetes mellitus race serum calcium
2018/12/14
Background: Elevated serum calcium has been associated with a variety of metabolic abnormalities and may be associated with a greater risk of diabetes.
Electromagnetic tunneling of obliquely-incident waves through a single-negative slab paired with a double-positive uniaxial slab
single-negative slab double-positive uniaxial slab
2011/9/2
We show that, under appropriate oblique-incidence and polarization conditions, the inherent opaqueness of a homogeneous, isotropic single-negative slab may be perfectly compensated (in the ideal lossl...
Uniqueness of the solution to inverse scattering problem with scattering data at a fixed direction of the incident wave
inverse scattering non-overdetermined data fixed direction of the incident wave scattering data
2011/1/21
Let q(x) be real-valued compactly supported sufficiently smooth func-tion. It is proved that the scattering data A( , 0, k) 8 2 S2, 8k > 0, determine q uniquely. Here 0 2 S2 is a fixed direction of...
Long-term patterns in dissolved organic carbon in boreal lakes: the role of incident radiation, precipitation, air temperature, southern oscillation and acid deposition
dissolved-organic-carbon lakes climate solar-radiation
2009/3/12
Both lake-specific (e.g. pH) and regional (e.g. precipitation) factors affect DOC concentration and pattern. Using annual DOC concentration in nine boreal lakes in the ice-free season, the potential i...
The Transmission and Decay of Barotropic Topographic Rossby Waves Incident on a Continental Shelf
Barotropic Topographic Rossby Waves Continental Shelf
2009/3/7
We know that long-period (>1 day) and long-wavelength (>100 km) topographical Rossby waves can be generated by a wind acting directly on a continental shelf (Adams and Buchwald, 1969). Here we examine...
Trench Wave Generation by Incident Baroclinic Rossby Waves
Trench Wave Incident Baroclinic Rossby Waves
2009/1/15
We consider the response of a two-layer fluid in a coastal trench to the incidence of low-frequency Rossby waves from the open ocean. While both barotropic and baroclinic incident waves have been inco...
Obliquely Incident Poincaré Waves on a Sloping Continental Shelf
Sloping Continental Shelf Obliquely Incident Poincaré Waves
2008/11/24
An analytical theory of barotropic tides propagating onto a sloping continental shelf from the deep ocean is developed. The plane Poincaré waves incident from the deep ocean are obliquely angled, and ...
Incident-Energy Dependence of the Effective Temperature in Heavy-Ion Collisions
Incident-Energy Dependence the Effective Temperature Heavy-Ion Collisions
2010/10/19
We study, in a hydrodynamical approach, the energy dependence of the kaon mT spectra in central Pb+Pb (Au+Au) collisions. We show that the experimental data of the inverse slope parameter can be repro...
