Information Seeking Regarding Tobacco and Lung Cancer: Effects of Seasonality
<div><p>This paper conducted one of the first comprehensive international Internet analyses of seasonal patterns in information seeking concerning tobacco and lung cancer. Search query data for the terms “tobacco” and “lung cancer” from January 2004 to January 2014 was collected from Google Trends. The relevant countries included the USA, Canada, the UK, Australia, and China. Two statistical approaches including periodogram and cross-correlation were applied to analyze seasonal patterns in the collected search trends and their associations. For these countries except China, four out of six cross-correlations of seasonal components of the search trends regarding tobacco were above 0.600. For these English-speaking countries, similar patterns existed in the data concerning lung cancer, and all cross-correlations between seasonal components of the search trends regarding tobacco and that regarding lung cancer were also above 0.700. Seasonal patterns widely exist in information seeking concerning tobacco and lung cancer on an international scale. The findings provide a piece of novel Internet-based evidence for the seasonality and health effects of tobacco use.</p></div

Reversible Morphology Switching of Colloidal Particles
A facile method has
been discovered that enables switching of non-cross-linked polyÂ(styrene)
(Nx-PS) colloidal particle morphologies, including spherical and anisotropic
convex–convex, plano–convex, and concave–convex.
The anisotropic morphologies can be achieved readily from spherical
Nx-PS particles through control of annealing time at elevated temperatures
or surfactant concentration. These anisotropic morphologies can be
reversed to spherical at lower temperatures, and reversible morphology
switching between any pair of anisotropic morphologies also can be
attained. This approach to particle morphology switching establishes
a straightforward method for the synthesis of designer anisotropic
particles using commercially available spherical particles as starting
materials
Disparity in entrainment strength within each user pair.
Here, EnDis is considered as a function over entrainment strength. Average EnDis in (a), (b), (c) are 0.431, 0.439, 0.828 respectively.</p
