The evolution of popular music: USA 1960-2010.

Royal Society open science

Mauch M, MacCallum RM, Levy M, Leroi AM.
PMID: 26064663
R Soc Open Sci. 2015 May 06;2(5):150081. doi: 10.1098/rsos.150081. eCollection 2015 May.

In modern societies, cultural change seems ceaseless. The flux of fashion is especially obvious for popular music. While much has been written about the origin and evolution of pop, most claims about its history are anecdotal rather than scientific...

A comparative and in-depth investigation on the reactivity of various Li-based electrolytes and of the solid electrolyte interface (SEI) formed at graphite electrode is carried out using X-ray photoelectron spectroscopy (XPS), chemical simulation test, and differential scanning calorimetry (DSC)....

THE SYMMETRY OF CORRELATED SELECTION RESPONSES IN ADAPTIVE EVOLUTION: AN EXPERIMENTAL STUDY USING DROSOPHILA.

Evolution; international journal of organic evolution

Shiotsugu J, Leroi AM, Yashiro H, Rose MR, Mueller LD.
PMID: 28568802
Evolution. 1997 Feb;51(1):163-172. doi: 10.1111/j.1558-5646.1997.tb02397.x.

The relationship between the processes of density-dependent and age-specific selection has been investigated by examining a common phenotype, urea resistance, which has apparently evolved in response to each of these selection mechanisms. Twenty populations that have experienced differing levels...

Geographical Clusters of Rape in the United States: 2000-2012.

Statistics and public policy (Philadelphia, Pa.)

Amin R, Nabors NS, Nelson AM, Saqlain M, Kulldorff M.

BACKGROUND: While rape is a very serious crime and public health problem, no spatial mapping has been attempted for rape on the national scale. This paper addresses the three research questions: (1) Are reported rape cases randomly distributed across...

Characterization of the mechanical properties of resected porcine organ tissue using optical fiber photoelastic polarimetry.

Biomedical optics express

Hudnut AW, Babaei B, Liu S, Larson BK, Mumenthaler SM, Armani AM.
PMID: 29082093
Biomed Opt Express. 2017 Sep 25;8(10):4663-4670. doi: 10.1364/BOE.8.004663. eCollection 2017 Oct 01.

Characterizing the mechanical behavior of living tissue presents an interesting challenge because the elasticity varies by eight orders of magnitude, from 50Pa to 5GPa. In the present work, a non-destructive optical fiber photoelastic polarimetry system is used to analyze...
