Patenting the HIF Power System Using the SPRFD
This paper discusses the rationale for patenting
inventions that enable the HIF power plant and the
status of the prosecution of these patents. Our
rationale for starting a business to pursue HIF
power was its “suspended animation” despite
being held since its 1976 debut to face “no
showstoppers” and considered to be “the
conservative approach to power production.” In
turn, the rationale for patenting the unique
features in our HIF approach is that intellectual
property (IP) is essential to attract investors to a
business endeavor that could readily be taken over
by large competitors..
Subsystem Tabulation of the Single Pass RF Driver
This paper presents a subsystem-by-subsystem
description of the Single Pass RF Driver (SPRFD).
The purposes are to show SPRFD’s relationships
to RF driver features assessed from 1976, to
isolate the differences that affect prior conclusions
about workability of RF drivers including
confidence in pellet ignition, and to highlight the
key associated technical issues to help prompt
experts in the various areas to appreciate the
specific challenges and perhaps become interested
in their assessment. For important context and to
show the excellent prospects for the complete HIF
power plant, the pellet and chamber subsystems
are likewise described and assessed..
The Properties of Brightest Cluster Galaxies in X-Ray Selected Clusters
We present the K-band Hubble diagram for 162 brightest cluster galaxies
(BCGs) in X-ray selected clusters, 0.01<z<0.83. The sample incorporates that of
Burke, Collins, & Mann (2000) and includes additional infrared data from the
2MASS extended source catalogue. We show that below z=0.1 the BCGs show no
correlation with their environment, however, above z=0.1 BCGs in more X-ray
luminous clusters are more uniform in their photometric properties. This
suggests that there may be two populations of BCGs which have different
evolutionary histories.Comment: 2 pages, to appear in the proceedings of the Sesto 2001 conference on
tracing cosmic evolution with galaxy cluster
Joint Comprehensive Plan of Action Opportunity for HIF in Iran
Cooperation in fusion energy research and
high-energy accelerators has been a “bridge over
troubled waters” for most of a century. Physics
research has traditionally been an international
endeavor, involving the earliest accelerator
developments, and hitting a hiatus only during
World War II. Fusion energy research using
magnetic confinement was internationalized by
the Geneva meeting in 1958. Iran is and has been
a participant in fusion research, even during the
troubles of the past couple decades..
Readiness of HIF Using the Single Pass RF Driver
Readiness for a concerted push to power production
was the underlying theme from the inaugural
HIF Workshop in 1976 through the review
of ICF programs by DOE’s Energy Research
and Advisory Board in 1979. Using John
Lawson’s 1987 paper “Whither Heavy Ion Fusion?”
[1] as a foil, this paper discusses the continuing
vitality of the argument for HIF’s readiness
against the backdrop that this vision is not
in evidence today, having been occluded by political
policies causing diversion of the HIF
community into peripheral science that, although
excellent, is in fact not required to complete
the development of a HIF energy source..

Theoretical Investigation of the Ground and Excited States of Coumarin 151 and Coumarin 120
We present calculations of various properties of the ground and excited states of Coumarins 151 and 120. These and related coumarins are important in investigating ultrafast solvation processes in liquids and complex solutions as well as being important acceptors in model electron-transfer systems. We calculate the following: (1) the electronic excitation energies to several low-lying singlet states, (2) ground and excited-state dipole moments, (3) solvation effects on excitation energies, and (4) the properties of single Coumarin 151-water complexes. We test our Time-Dependent Density Functional Theory (TDDFT) calculations against CASSCF, CASPT2 (both single and multistate versions), CIS, and ZINDO. Using TDDFT, we find excellent agreement with experimental S1 ← S0 excitation energies. On the basis of these results, we address several outstanding questions for these systems and find: (1) that TICT-formation is unlikely upon photexcitation for gas-phase C151, (2) a greater tendency toward a planar amine group for the S1 state than for the ground state, (3) significant differences between our gas-phase ground-state dipole moment and the experimental value, and (4) TDDFT results for water−Coumarin 151 complexes are in good agreement with the experimental results of Topp and co-workers

The house sparrow (Passer domesticus) is an important model species in ecology and evolution. However, until recently, genomic resources for molecular ecological projects have been lacking in this species. Here, we present transcriptome sequencing data (RNA-Seq) from three different house sparrow tissues (spleen, blood and bursa). These tissues were specifically chosen to obtain a diverse representation of expressed genes and to maximize the yield of immune-related gene functions. After de novo assembly, 15250 contigs were identified, representing sequence data from a total of 8756 known avian genes (as inferred from the closely related zebra finch). The transcriptome assembly contain sequence data from nine manually annotated MHC genes, including an almost complete MHC class I coding sequence. There were 407, 303 and 68 genes overexpressed in spleen, blood and bursa, respectively. Gene ontology terms related to ribosomal function were associated with overexpression in spleen and oxygen transport functions with overexpression in blood. In addition to the transcript sequences, we provide 327 gene-linked microsatellites (SSRs) with sufficient flanking sequences for primer design, and 3177 single-nucleotide polymorphisms (SNPs) within genes, that can be used in follow-up molecular ecology studies of this ecological well-studied species
The Physical Activity–Related Barriers and Facilitators Perceived by Men Living in Rural Communities
Men, especially those living in rural areas, experience chronic disease at higher rates than the general population. Physical activity is a well-established protective factor against many chronic diseases; however, only a small fraction of men are meeting national guidelines for physical activity. The purpose of this study was to examine the perceived physical activity–related barriers and facilitators experienced by men living in rural areas in Canada. Participants completed a paper-and-pencil or online survey and asked to select personally relevant physical activity-related barriers and facilitators from a list of 9 and 10 choices, respectively. A total of 149 men completed the survey (50.3% between the ages of 18 and 55 years; 43.0% older than 55 years). Participants were predominantly from rural areas and smaller communities. Overall, the response options “I’m too tired,” “I don’t have enough time,” and “I think I get enough exercise as work” were the three most frequently cited barriers to regular physical activity. The response options “Personal motivation to be healthy,” “I enjoy it,” and “Support from family and/or friends” were the three most often cited facilitators to physical activity. Results are similar to those shown in other populations. Results can be used to inform the development of policies and programs that aim to increase the physical activity levels of men living in rural areas and small communities
