Phospho-tau with subthreshold tau-PET predicts increased tau accumulation rates in amyloid-positive individuals

Different tau biomarkers become abnormal at different stages of Alzheimer's disease, with CSF phospho-tau typically becoming elevated at subthreshold levels of tau-PET binding. To capitalize on the temporal order of tau biomarker-abnormality and capture the earliest changes of tau accumulation, we implemented an observational study design to examine longitudinal changes in Tau-PET, cortical thickn

Information Economics in the Criminal Standard of Proof

In this paper we model the criminal standard of proof as a twofold standard requiring sufficient probability of the factum probandum and sufficient informativeness. The focus of the paper is on the latter requirement, and we use decision theory to develop a model for sufficient informativeness. We demonstrate that sufficient informativeness is fundamentally a question of information economics and

“Self-created person-centred care” – a new notion in eldercare services?

BackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being. In this context, they have to create their own sense of meaningfulness in their everyday life, despite being subject to social care services.Methods As part of a research prBackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being.

Upconversion phosphor thermometry for use in thermal barrier coatings

Measuring the temperature below the surface of a thermal barrier coating (TBC) using a thin phosphor layer is challenging primarily due to the absorption and scattering of laser excitation light and phosphor luminescence as they propagate through the coating. One way to increase phosphor luminescence could be to use upconversion phosphor thermometry, which is investigated in the current study. It

A comparison of three meshless algorithms : Radial point interpolation, non-symmetric and symmetric Kansa method

Three different meshless methods based on radial basis functions are investigated for the numerical solution of electromagnetic eigenvalue problems. The three algorithms, the non-symmetric Kansa approach, the symmetric Kansa method and the radial point interpolation method, are first described putting emphasis on the influence of their formalism on practical implementation. The convergence rate of

Eigenvalue analysis and longtime stability of resonant structures for the meshless radial point interpolation method in time domain

A meshless collocation method based on radial basis function (RBF) interpolation is presented for the numerical solution of Maxwell's equations. RBFs have attractive properties such as theoretical exponential convergence for increasingly dense node distributions. Although the primary interest resides in the time domain, an eigenvalue solver is used in this paper to investigate convergence properti

How is parental education associated with infant and young child feeding in Bangladesh? a systematic literature review

BackgroundEducation is expected to bring about positive behavioral changes which could lead to improved health behaviors. Parental education is a primary determinant of child health and development. However, some evidence showed inverse associations between high parental education and recommended infant and young child feeding (IYCF) in Bangladesh. How the association of parental education differs
