Tooth chipping can reveal bite forces and diets of fossil hominins

Author(s)
Paul Constantino, James J. Lee, H Chai, Bernhard Zipfel, Charles Ziscovici, Brian R. Lawn, Peter Lucas
Fossil hominin tooth enamel often exhibits antemortem edge chipping (Robinson 1954; Tobias 1967; Wallace 1973). Here we apply a simple fracture equation to

Low temperature magnetic properties of Cd-doped Ce 2MIn 8 (M = Rh and Ir) single crystals are investigated. Experiments of temperature dependent magnetic

Edge structure of epitaxial graphene islands

Author(s)
Gregory M. Rutter, N Guisinger, Jason Crain, Phillip N. First, Joseph A. Stroscio
Graphene islands grown epitaxially on 6H-SiC(0001) were studied using scanning tunneling microscopy and spectroscopy. Under specific growth conditions,

Dark pulse quantum dot diode laser

Author(s)
Mingming M. Feng, Kevin L. Silverman, Richard P. Mirin, Steven T. Cundiff
We describe an operating regime for passively mode-locked quantum dot diode laser where the output consists of a train of dark pulses, i.e., intensity dips on a

Ultraviolet Weathering of Firefighter Protective Clothing

Author(s)
Rick D. Davis, Joannie W. Chin, Chiao-Chi Lin, Sylvain H. Petit
Exposure to simulated ultraviolet sunlight at 50 C and 50 % relative humidity caused a significant deterioration in the mechanical performance of polyaramid

Monte-Carlo Reaction Rate Evaluation for Astrophysics

Author(s)
Ryan P. Fitzgerald, A. Coc, R Longland, A E. Champagne
We present a new evaluation of thermonuclear reaction rates for astrophysics involving proton and a-particle induced reactions, in the target mass range between

Adding Attributes to Role Based Access Control

Author(s)
David R. Kuhn, Edward Coyne, Timothy Weil
Role based access control (RBAC) is a popular model for information security. It helps reduce the complexity of security administration and supports the review
