Measuring high-density built environment for public health research: Uncertainty with respect to data, indicator design and spatial scale

open access: yesGeospatial Health, 2018
Uncertainty with respect to built environment (BE) data collection, measure conceptualization and spatial scales is evident in urban health research, but most findings are from relatively lowdensity contexts. We selected Hong Kong, an iconic high-density

Combining Density Functional Theory and Density Matrix Functional Theory

open access: yes, 2010
We combine density-functional theory with density-matrix functional theory to get the best of both worlds. This is achieved by range separation of the electronic interaction which permits to rigorously combine a short-range density functional with a long-

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Advantages of lateral BMD DEXA measurement and concomitant lateral spinal imaging at the point of service over conventional PA measurement in the estimation of BMD

open access: yesSouth African Journal of Radiology, 2003
This study examined 144 sequentially selected female patients with a mean age of 53.4 years. The purpose was to assess whether instant vertebral assessment (IVA) and lateral DEXA bone mineral density (BMD) measurement in the lumbar spine would render a ...

High density matter

open access: yes, 2013
The microscopic composition and properties of matter at super-saturation densities have been the subject of intense investigation for decades. The scarcity of experimental and observational data has lead to the necessary reliance on theoretical models ...

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair

open access: yesFEBS Letters, EarlyView.
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Modelling the Density of Inflation Using Autoregressive Conditional Heteroscedasticity, Skewness, and Kurtosis Models [PDF]

open access: yes
The paper aimed at modelling the density of inflation based on time-varying conditional variance, skewness and kurtosis model developed by Leon, Rubio, and Serna (2005) who model higher-order moments as GARCH-type processes by applying a Gram-Charlier ...

Bone Density Status and Vitamin D and Calcium Concentrations in Pregnant and Non-Pregnant Women [PDF]

open access: yes, 2016
Background: The aim of this study was to analyse differences in bone density and vitamin D and calcium concentrations between pregnant and non-pregnant women. Methods: This was an analytical, cross-sectional study of women aged 30 years or over, residing

Dynamical density-density correlations in one-dimensional Mott insulators

open access: yes, 1996
The dynamical density-density correlation function is calculated for the one-dimensional, half-filled Hubbard model extended with nearest neighbor repulsion using the Lanczos algorithm for finite size systems and analytically for large on site repulsion ...
