A New 26plex Autosomal STR Assay to Aid Human Identity Testing*(dagger)

September 1, 2009
Author(s)
Carolyn R. Steffen, John M. Butler, Peter Vallone
Multiplex polymerase chain reaction (PCR) has become the standard in forensic testing. Currently there are two commercial multiplex PCR amplification kits available that simultaneously amplify 16 short tandem repeat (STR) loci that include the 13 FBI

Economic Analysis of Egress and Life Safety Costs

April 27, 2009
Author(s)
Robert E. Chapman, Allison L. Huang, David T. Butry
In 2007, the latest year for which construction data are available, the value of construction put in place was $1.1 trillion. Statistics on the total cost of fire in the U.S. are published by the National Fire Protection Association (NFPA). Of particular

Preparation and Characterization of Patchy Particles

November 14, 2008
Author(s)
Thuy Chastek, Steven D. Hudson, Vincent A. Hackley
The self-assembled organization of partilces depends on the symmetry of their interactions, and strides are being made in producing nanoaparticles of controlled shape and functionalization. This paper describes the use of particles adsorption to control

Hollow spherical supramolecular dendrimers

October 1, 2008
Author(s)
Virgil Percec, Mihai Peterca, Andres E. Dulcey, Mohammad Imam, Steven Hudson, Sami Nummelin, Peter Adelman, Paul A. Heiney
The synthesis of a library containing 12 conical dendrons that self-assemble into hollow spherical supramolecular dendrimers is reported. The design principles for this library were accessed by development of a method that allows the identification of

Quantifying Changes in the Fast Dynamics of Mixtures by Dielectric Spectroscopy

September 26, 2008
Author(s)
Tatiana Psurek, Christopher L. Soles, Kirt A. Page, Marcus T. Cicerone, Jack F. Douglas
The addition of a solvent or nanoparticles to a polymeric material can lead toappreciable changes in the rates of relaxation and reaction that can profoundly alter material properties and function. We introduce a general theoretical strategy for

Interference Avoidance in Rapidly Deployed Wireless Ad hoc Incident Area Networks

April 18, 2008
Author(s)
Mohamed T. Refaei, Nader Moayeri, Michael R. Souryal
A common strategy for responding to indoor emergency scenarios is to rapidly deploy a group of first responders inside the incident area and an incident command center outside of the incident area. First responders are equipped with radios that allow them

Equi-Axed Grain Formation in Electrodeposited Sn-Bi

December 29, 2007
Author(s)
E Sandnes, Maureen E. Williams, Mark D. Vaudin, Gery R. Stafford
Sn is widely used as a coating in the electronics industry because it provides excellent solderability, ductility, electrical conductivity and corrosion resistance. However, Sn whiskers have been observed to grow spontaneously from Sn electrodeposits and

Improving CNC Machining Accuracy Through Thermal Model-Based Control

July 21, 2004
Author(s)
John L. Michaloski, Frederick M. Proctor, Johannes A. Soons, R King, W Bakula, H Dominguez, N Frampton
The United States Army has a requirement to machine munitions to strict tolerances so that the munitions will launch properly and the explosives will detonate correctly. High precision parts require machine tools to operate with a high degree of accuracy

Improving CNC Machining Accuracy Through Thermal Model-Based Control

Elastic Flow Instability, Curved Streamlines and Mixing in Microfluidic Flows

February 1, 2004
Author(s)
Jai A. Pathak, David J. Ross, Kalman D. Migler
Flow instabilities are well known to occur in macroscopic flows when elastic fluids flow along curved streamlines. In this work we use flow visualization to study the mechanism underlying a purely elastic flow instability for Poiseuille flow in a micro (m)

Evaluation and Selection in Product Design for Mass Customization

January 1, 2004
Author(s)
XuanFang Zha, Ram D. Sriram, W F. Lu, Fujun Wang
Mass customization has been identified as a competitive strategy by an increasing number of companies. Family-based product design has been recognized as an efficient and effective means to realize sufficient product variety to satisfy a range of customer

Self-Organization of Supramolecular Helical Dendrimers Into Complex Electronic Materials

September 1, 2002
Author(s)
Virgil Percec, A Rapp, Hans -. Spiess, Steven Hudson, H Duan, M Glodde, T K. Bera, Y Miura, I Shiyanovskaya, K D. Singer, V S. Balagurusamy, Paul A. Heiney, I Schnell
The discovery of electrical conduction in organic crystals and polymers has widened the range of potential optoelectronics materials, provided these exhibit sufficiently high charge carrier mobilities and are easy to make and process. Organic single
