Abstract The Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL) is a collaboration of Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory, and Princeton Plasma Physics Laboratory. These laboratories, in cooperation with researchers at other institutions, are carrying out a coordinated effort to apply intense ion beams as drivers for studies of the physics ...

The potential of therapeutic peptides to address a growing range of diseases has gained increasing recognition in recent years. Due mainly to their poor stability and short plasma half-life, peptides are usually administered by injection, often several times daily. Injectable sustained-release formulations of peptides demonstrated the power of drug delivery technologies to enhance patient adher...

Co-rotating interaction regions (CIRs) between fast and slow streams of plasma are a prominent feature of the solar wind. Measurements of interplanetary scintillation (IPS) using the three widely separated antennas of the EISCAT facility have been used to detect the compression regions at the leading edges of interaction regions and to determine the location and velocity of the structure. Obser...

The slow-wave dispersive properties of a traveling-wave tube (TWT) changes considerably when either the helix is supported by a dielectric or the waveguide is filled with plasma. The dispersive properties of the dielectric-supported helix waveguide have been examined for different geometric parameters of the helix waveguide. The dispersion relation of the helix mode is found to be upshifted by ...

In this article we describe a new slit grating spectrograph which is based on an e-beam written 10 000 linepairs/mm freestanding transmission diffraction grating. In combination with a thinned, back-illuminated charge coupled device ~CCD!, the spectrograph allows for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength region l51–20 nm. Calibration of grating and ...

In this contribution we present a few selected examples of how the latest generation of space-based instrumentation – NASA’s Chandra X-ray Observatory and the Far-Ultraviolet Spectroscopic Explorer (FUSE) – are finally answering old questions about the influence of massive star feedback on the warm and hot phases of the ISM and IGM. In particular, we discuss the physical origin of the soft ther...

Realistic description of patient-specific mechanical properties of clotting dynamics presents a major challenge. Available patient-specific data falls short of robustly characterizing myriads of complex dynamic interactions that happen during clotting. We propose a simplified switching model for a key part of the coagulation cascade that describes dynamics of just four variables. The model corr...

We compare observations of the non-flaring solar corona made simultaneously with Hinode/XRT and with RHESSI. The analyzed corona is dominated by a single active region on 12 November 2006. The comparison is made on emission measures. We derive emission measure distributions vs temperature of the entire active region from multifilter XRT data. We check the compatibility with the total emission m...
