Detection and Characterization of Selenoproteins by Tandem Mass Spectrometry Assisted by Laser Ablation Inductively Coupled Plasma Mass Spectrometry: Application to Human Plasma Selenoproteins

October 22, 2010
Author(s)
Guillaume Ballihaut, Lisa Kilpatrick, Eric L. Kilpatrick, William Davis
There has been an on-going effort and long term goal to accurately assess selenium status and selenium nutritional requirement in humans through the quantification of human plasma selenoprotein P (SelP) and glutathione peroxidase 3 (GPx3). To achieve this

Intrusion Detection and Prevention Systems

October 22, 2010
Author(s)
Karen A. Scarfone, Peter M. Mell
Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of possible incidents. An intrusion detection and prevention system (IDPS) is software that automates the intrusion detection

Structural Analysis of Soft Multicomponent Nanoparticle Clusters Using Electrospray Differential Mobility Analysis with Transmission Electron Microscopy

October 22, 2010
Author(s)
Leonard F. Pease , Jeremy Feldblyum, Silvia H. DePaoli Lacaerda, Rajesekhar Anumolu, Peter Yim, Matthew L. Clarke, Hyeong G. Kang, Jeeseong C. Hwang
Rapid and quantitative techniques are essential to analyze soft multicomponent nanoparticle clusters. Here we combine electrospray differential mobility analysis (ES-DMA), which measures the size of the entire cluster, with transmission electron microscopy

The evolving optical frequency comb

October 22, 2010
Author(s)
Scott A. Diddams
Much as natural historians search for the first roots of our human race, curiosity drives the laser scientist to pursue the roots of his or her own field. This is especially the case in this year where our community celebrates the 50th anniversary of the

A Focused Chromium Ion Beam

October 21, 2010
Author(s)
Adam V. Steele, Brenton J. Knuffman, Jabez J. McClelland, Jon Orloff
With the goal of expanding the capabilities of focused ion beam microscopy and milling systems, we have demonstrated nanoscale focusing of chromium ions produced in a magneto-optical trap ion source (MOTIS). Neutral chromium atoms are captured into a
