The parabolic wave equation has been used extensively to model long-range paraxial wave propagation due to its high computational efficiency. Typical radar, sonar, and communication geometries are most naturally treated using cylindrical coordinates

A non-destructive technique for obtaining voltage contrast information with photoelectron emission microscopy is described. Samples consisting of electrically isolated metal lines were used to quantify voltage contrast in photoelectron emission micro

Terahertz (THz) vibrational modes are characterized by nonlocal, collective molecular motions which are relevant to conformational changes and molecular functions in biological systems. We have investigated the THz spectra of a set of small bionanotu

High-resolution terahertz absorption spectra (0.06-3 THz) have been obtained at 4.2 K for three crystalline forms of trialanine [H2+-(Ala)3-O-]. The crystal structures differ in their beta-sheet forms (parallel vs antiparallel) and in their water com

Parvovirus B19-induced chronic anemia has been associated with failure to mount an effective neutralizing antibody response. We describe an adolescent male with a 13-year history of parvovirus B19-induced anemia as the primary manifestation of X-link

JHU/APL conducted solid propellant fire characterization tests in warm, humid, ambient conditions near sea level. Yttria and ceria surrogate materials were placed in the fires. The substrates simulating ground surfaces were concrete from a Kennedy Sp

As part of our routine work-up in the diagnosis of lymphoprolife rative disease, we used a rapid polymerase chain reaction (PCR) assay to amplify the DNA fragments of the framework 3 (FR3) region of the immunoglobulin heavy (IgH) chain genes. The ass

This paper presents the first, to our knowledge, direct measurement of aerosol produced by an aluminized solid rocket propellant (SRP) fire on the ground. Such fires produce aluminum oxide particles small enough to loft high into the atmosphere and d

To develop a deeper understanding of the optical signatures of both biological aerosols and potential interferents, we made field measurements of optical cross sections and compared them to model-based predictions. We measured aerosol cross sections

Vibrationally state-resolved THz spectra are obtained at cryogenic temperatures for three crystalline peptide-water systems that represent different structural motifs. The systems include two types of secondary structures and a hydrophobic peptide na
