The static and dynamic response associated with a low concentration x of static defects in a Heisenberg antiferromagnet at zero temperature is analyzed within linearized spin-wave theory via a boson formalism involving a non-Hermitian potential. We obtain the dispersion relation for long-wavelength spin waves in the form ω(q)=c(x)q+iγ(x)qτ. Our results for c(x) agree with previous work and, in ...

PURPOSE To determine which resources residents use at the point-of-care (POC) for decision making, the drivers for selection of these resources, and how residents use Google/Google Scholar to answer clinical questions at the POC. METHOD In January 2012, 299 residents from three internal medicine residencies were sent an electronic survey regarding resources used for POC decision making. Resou...

The High-Order Maximal Principle (HMP) [15] is one of the first among A. Krener’s many major contributions to modern control theory. While some precursors had appeared in the literature in earlier years, compare the discussions in [15] and in the abbreviated announcement [14], it was [15] that became the starting point for much research in the next decades, continuing to this day – typical for ...

The computer revolution is less a revolution in the usual sense of the word than the announcement of a glamorous marriage between two powerful promises in the history of the modern West, the Enlightenment, the impulse to encompass the entire world in a rational system of knowledge, and the Industrial Revolution, the fruit of an ancient impulse to reduce the demands of nature to insignificance. ...

We give a simple theory for recent experiments of Bar-Ziv and Moses [Phys. Rev. Lett. 73, 1392 (1994)] in which tubular vesicles are excited using laser tweezers to a "peristaltic" state. Considering the hydrodynamics of a bilayer membrane under tension, we reproduce some of the qualitative behavior seen and find a value for the wavelength of the instability in terms of independently measured m...

A recent experiment located the lowest 2+ state in 20Mg and discovered that the corresponding 2+, T = 2 state in 20F does not fit expectations of the isobaric multiplet mass equation without a d term.We have calculated the energies of the ground and 2+ states in 20Mg and the 2+ in 20F in a potential model, using shell-model spectroscopic factors. We conclude that this important 20F state has li...

In the last two decades, scanning probe microscopies (SPMs) have become the primary tool for addressing structure and electronic, mechanical, optical, and transport phenomena on the nanometer and atomic scales. Here, we summarize basic principles of SPM as applied for oxide materials characterization and present recent advances in high-resolution imaging and local property measurements. The use...

3D printing opens up an inexpensive, rapid, and versatile path to the fabrication of optical elements suited to the terahertz regime. The transmission of the plastics used in 3D printers, while generally decreasing with frequency, is usable over the range 0.1-2 THz. We have designed, fabricated, and tested regular and blazed gratings and aspherical lenses for operation at terahertz frequencies....
