Discussion of Review of Methods to Assess, Design for, and Mitigate Multiple Hazards by Yue Li, Aakash Ahuja, and Jamie E. Padgett (J. Performance of Constructed Facilities, 26 104-117)

March 1, 2013
Author(s)
Dat Duthinh, Long T. Phan, Emil Simiu
The authors have performed a useful service by providing a broad perspective on multi-hazard engineering. The discussers would like to complement that perspective by noting two results of practical significance in the context of design for multiple hazards

Gradient Nanofiber Scaffold Libraries for Screening Cell Response to Poly(e-caprolactone)-Calcium Phosphate Composites

March 1, 2013
Author(s)
Carl G. Simon Jr., Limin Sun, Laurence C. Chow, William Miles, Christopher K. Tison, Kaushik Chatterjee, Marian F. Young, Vinoy Thomas, Murugan Ramalingam
A 2-spinnerette approach has been developed for fabricating nanofiber scaffold gradients for use as 1) scaffold libraries for screening the effect of nanofiber properties on cell response and 2) templates for generating graded tissue interfaces. Although

Long-Wavelength Beam Steerer Based on a Micro-Electromechanical Mirror

March 1, 2013
Author(s)
Eyal Gerecht, Anthony B. Kos
Commercially available mirrors for scanning THz beams are too large to allow high-speed THz imaging. There is a need for smaller, more agile pointing apparatus to provide THz images in seconds, not minutes or hours. We have developed a fast THz beam

Standard Reference Material 2366 for Measurement of Human Cytomegalovirus DNA

March 1, 2013
Author(s)
Ross J. Haynes, Margaret C. Kline, Blaza Toman, Calum Scott, Paul Wallace, John M. Butler, Marcia J. Holden
Cytomegalovirus (CMV) is one of a number of human viruses that are ubiquitous in human populations, generally cause little illness upon infecting healthy individuals, but can cause life threatening disease in immune-compromised individuals. An important

Experimental Study of the Thermal Conductivity of Water +Ammonia Refrigerant Mixtures at Temperatures from 278 K to 356 K and at Pressures up to 20 MPa

February 28, 2013
Author(s)
F. N. Shamsetdinov, Z. I. Zaripov, Ilmutdin M. Abdulagatov, Marcia L. Huber, F. M. Gumerov, F. R. Gabitov, Andrei F. Kazakov
The thermal conductivity of binary water + ammonia mixtures was measured over the temperature range from 278 K to 356 K and at pressures up to 20 MPa using the steady-state hot-wire method. Measurements were made for eight compositions over the entire

Frequency-Modulated Charge Pumping: Defect Measurements with High Gate Leakage

February 28, 2013
Author(s)
Jason T. Ryan, Richard G. Southwick, Jason P. Campbell, Kin P. Cheung, John S. Suehle, Anthony Oates
Charge pumping is one of the most relied upon techniques used to quantify interface defects in metal-oxide-semiconductor devices. However, conventional charge pumping is easily hindered by excessive gate leakage currents which render the technique

In situ monitoring of atmospheric methane using a dense network in the Northeastern U.S.

February 28, 2013
Author(s)
Kuldeep R. Prasad, Elena Novakovskaia, Marc Fischer, Chris Sloop
Methane (CH4) is one of the major greenhouse gases with a CO2–relative global warming potential above 20 over a 100-year period (IPCC TAR). Global average concentration of this tracer in Earth's atmosphere is increasing due to widely spread surface sources

Organosilicate Polymer E-Beam Resists with High Resolution, Sensitivity and Stability

February 28, 2013
Author(s)
Christopher Soles, Richard Kasica, Hae-Jeong Lee, Jae H. Sim, Sung-Il Lee, Ki-Bum Kim, Hyun-Mi Kim, Do Y. Yoon
Hydrogen silsesquioxane (HSQ) is an attractive electron-beam (e-beam) resist for sub-20 nm lithography due to its high resolution, excellent line-edge-roughness (LER), and good plasma etch resistance. However, the sensitivity and long-term stability of HSQ

Delivering Building Intelligence to First Responders

February 27, 2013
Author(s)
David G. Holmberg, Michelle A. Raymond, Jason D. Averill
Presently, there is no integrated solution for delivering building systems data into the hands of emergency responders. A standard building data delivery solution will integrate the capacity of the building fire safety systems with the capabilities of the

Effect of atomic coherence on "temporal cloaking" in atomic vapors

February 27, 2013
Author(s)
Runbing Li, Lu Deng, Edward W. Hagley, Joshua C. Bienfang, M G. Payne, Mo-Lin Ge
We discuss a different scheme to achieve temporal cloaking in warm atomic vapors. Instead of creating a temporal-spatial window in a patched broadband short optical pulse using static differential dispersion of an optical fiber, we create a temporal

Modification of tethered bilayers by phospholipid exchange with vesicles

February 27, 2013
Author(s)
David J. Vanderah, Rima Budvytyte, Mindaugas Mickevicius, Gintaras Valincius, Frank Heinrich
Phosphatidylcholine and cholesterol exchange between vesicles and planar tethered bilayer lipid membranes (tBLMs) was demonstrated from electrochemical impedance spectroscopy (EIS), fluorescence microscopy (FM), and neutron reflectometry (NR) data

Robustness of Steel Gravity Frame Systems with Single-Plate Shear Connections

February 27, 2013
Author(s)
Joseph A. Main, Fahim Sadek
This report presents a computational assessment of the performance of steel gravity framing systems with single-plate shear (“shear tab”) connections and composite floor slabs under column loss scenarios. The computational assessment uses a reduced
