Deterministic excitable media under Poisson drive: Power law responses, spiral waves, and dynamic range
Tiago L. Ribeiro and Mauro Copelli
When each site of a spatially extended excitable medium is independently driven by a Poisson stimulus with rate h, the interplay between creation and annihilation of excitable waves leads to an average activity F. It has recently been suggested that in the low-stimulus regime (h~0) the response func ... [Phys. Rev. E 77, 051911 (2008)] published Wed May 14, 2008.
Single-sweep methods for free energy calculations
Luca Maragliano and Eric Vanden-Eijnden
A simple, efficient, and accurate method is proposed to map multidimensional free energy landscapes. The method combines the temperature-accelerated molecular dynamics (TAMD) proposed in [L. Maragliano and E. Vanden-Eijnden, Chem. Phys. Lett. 426, 168 (2006)] with a variational reconstruction method ... [J. Chem. Phys. 128, 184110 (2008)] published Wed May 14, 2008.
Interplay between a phase response curve and spike-timing-dependent plasticity leading to wireless clustering
Hideyuki Cateau, Katsunori Kitano, and Tomoki Fukai
A phase response curve (PRC) characterizes the signal transduction between oscillators such as neurons on a fixed network in a minimal manner, while spike-timing-dependent plasiticity (STDP) characterizes the way of rewiring networks in an activity-dependent manner. This paper demonstrates that thes ... [Phys. Rev. E 77, 051909 (2008)] published Tue May 13, 2008.
c-erbB-2 sensing using AlGaN/GaN high electron mobility transistors for breast cancer detection
K. H. Chen, B. S. Kang, H. T. Wang, T. P. Lele, F. Ren et al.
Antibody-functionalized, Au-gated AlGaN/GaN high electron mobility transistors (HEMTs) were used to detect c-erbB-2, which is a breast cancer marker. The antibody was anchored to the gate area through immobilized thioglycolic acid. The AlGaN/GaN HEMT drain-source current showed a rapid response of l ... [Appl. Phys. Lett. 92, 192103 (2008)] published Mon May 12, 2008.
On HIV Prevalence and AIDS Deaths in India
B. D. Aggarwala
The National AIDS Control Organization (NACO) of India had estimated, before this year, that there were 5.134 million HIV positive people in India at the end of 2004 and that they were increasing at the rate of more than a quarter of a million people every year. In a recent publication, we estimated ... [AIP Conf. Proc. 1007, 235 (2008)] published Mon May 12, 2008.
Respiratory System Model for Quasistatic Pulmonary Pressure-Volume (P-V) Curve: Inflation-Deflation Loop Analyses
R. Amini and U. Narusawa
A respiratory system model (RSM) is developed for the deflation process of a quasistatic pressure-volume (P-V) curve, following the model for the inflation process reported earlier. In the RSM of both the inflation and the deflation limb, a respiratory system consists of a large population of basic ... [J. Biomech. Eng. 130, 031020 (2008)] published Fri May 9, 2008.
