Surface structure of thin asymmetric PS-b-PMMA diblock copolymers investigated by atomic force microscopy [PDF]
Asymmetric poly(styrene-b-methyl methacrylate) (PS-b-PMMA) diblock copolymers of molecular weight M-n = 29,700g mol(-1) (M-PS = 9300 g mol(-1) M-PMMA = 20,100 g mol(-1), PD = 1.15, chi(PS) = 0.323, chi(PMMA) = 0.677) and M-n = 63,900 g mol(-1) (M-PS = 50,

Impact of regional white matter hyperintensity patterns on cognitive trajectories in NACC
Abstract INTRODUCTION White matter hyperintensities (WMHs) are a biomarker of small vessel cerebrovascular changes that can emerge early in Alzheimer's disease. While global WMHs correlate with cognitive decline, the impact of regional WMHs remains understudied.

ABSTRACT Background The definition of clinical obesity was newly announced. The aim of our study was to investigate the association of preclinical obesity and clinical obesity either at baseline or determined during follow‐ups with the risk of all‐cause mortality. Methods Data were collected from 232,721 participants in the UK Biobank.

Devil in the Details – Visual Perception of the Landscape Features by Potential Residential Buyers
It has long been established that people attach value to window views. However, the challenge in real estate market analyses is to capture what landscape features an attractive view contains and thus how they affect the worth (individual valuation) of ...

CN and HCN in Dense Interstellar Clouds
We present a theoretical investigation of CN and HCN molecule formation in dense interstellar clouds. We study the gas-phase CN and HCN production efficiencies from the outer photon-dominated regions (PDRs) into the opaque cosmic-ray dominated cores.

Neutrals Ejected From Io's Plasma/Atmosphere Interaction Region by Physical Chemistry Processes
Abstract Neutrals ejected from Io's atmosphere are the source of many important structures of the jovian magnetosphere: they feed giant neutral clouds, which extend along Io's orbit and nebulae, which extend beyond 500 jovian radii. The neutral loss rate is casually claimed to be ∼1 ton/s, but the processes leading to this loss, their quantitative ...
