Local streamline generation by mechanical oscillation in a microfluidic chip for noncontact cell manipulations Masaya Hagiwara, Tomohiro Kawahara, and Fumihito Arai
Authors demonstrate noncontact cell manipulations using local streamline in a microfluidic chip. Various patterns of streamline can be generated by oscillating a tool with high frequency and the pattern of the streamline can be controlled by the oscillation configurations.
Taking whispering gallery-mode single virus detection and sizing to the limit V. R. Dantham, S. Holler, V. Kolchenko, Z. Wan, and S. Arnold
Researchers at The Polytechnic Institute of New York University and collaborators have detected and sized the smallest aqueous borne RNA virus with a limit of detection in the protein realm (molecular weight of 240 kDa) and below that of all known virus. Detection was accomplished by measuring the frequency shift of a hybrid nanoplasmonic-Whispering-Gallery-Mode of a microspherical resonator as light forces drew the virus to a nanoplasmonic hot spot.
Spin waves turning a cornerK. Vogt, H. Schultheiss, S. Jain, J. E. Pearson, A. Hoffmann, S. D. Bader, and B. Hillebrands
Researchers demonstrate spin-wave propagation inside an S-shaped bend of a nickel-iron waveguide using a generated local magnetic field. This is in contrast to the case of an externally applied magnetic field, which generates strong inhomogeneities in the internal effective field distribution, preventing any spin-wave propagation across the bend.
On the link between electroluminescence, gate current leakage, and surface defects in AlGaN/GaN high electron mobility transistors upon off-state stressM. Montes Bajo, C. Hodges, M. J. Uren, and M. Kuball
Researchers from the University of Bristol have studied the degradation of AlGaN/GaN high electron mobility transistors using electroluminescence, current monitoring, and atomic force microscopy. Electroluminescent spots are correlated with surface pitting and current leakage in the devices studied.
Network analyzer measurements of spin transfer torques in magnetic tunnel junctionsLin Xue, Chen Wang, Yong-Tao Cui, J. A. Katine, R. A. Buhrman, and D. C. Ralph
Researchers demonstrate a simple network-analyzer technique to make quantitative measurements of the bias dependence of spin torque in a magnetic tunnel junction. By applying a microwave current near the ferromagnetic resonance frequency of the tunnel junction’s free layer, the team generates a microwave signal that is fed into the network analyzer. An analysis of the resonant response yields the strength and direction of the spin torque at non-zero bias.

Celebrating APL’s 50th Anniversary!
The first year of Applied Physics Letters ran approximately 8 articles every two weeks. Since the first issue, published in September 1962, the Journal has evolved to meet the changing needs of the scientific community and to follow the trends of the applied physics field. In 2011, a week’s worth of Applied Physics Letters amounts to about 85 articles per issue across a broad range of topics, all highly relevant and highly cited.
Now, as APL enters its fiftieth year of serving the needs of physicists and scientists around the globe, we invite you to not only look back at the most highly cited papers from the past 50 years, but also to look forward to another 50 exciting years on the cutting edge of scientific discovery!
