Fibroblastic reticular cells (FRCs) form the cellular scaffold of lymph nodes (LNs) and establish distinct microenvironmental niches to provide key molecules that drive innate and adaptive immune responses and control immune regulatory processes. Here, we have used a graph theory-based systems biology approach to determine topological properties and robustness of the LN FRC network in mice. We ...

Airbus Industrie is considering building a family of double-deck aircraft. A research project was initiated primarily to investigate the effects of the height of the new upper deck on human performance in case of an emergency, but it was also investigated whether factors such as visibility, slide design, and passenger safety instruction might influence individuals‘ performance. A performance mo...

This paper presents a novel and practical procedure for estimating the mean deck height to assist in automatic landing operations of a Rotorcraft Unmanned Aerial Vehicle (RUAV) in harsh sea environments. A modified Prony Analysis (PA) procedure is outlined to deal with real-time observations of deck displacement, which involves developing an appropriate dynamic model to approach real deck motio...

A field reversed configuration (FRC) plasma device is being developed at AFRL Edwards. This geometry concept is based off of the coaxial slow source FRC fusion reactor concept developed at the University of Washington by Vlases, et al. A scaling energy model, COTS FEA, and a proof-of-concept experiment have been completed. In addition a complete suite of magnetic diagnostics as well as photomet...

Introduction: Application of light transmitting posts to restore greatly damaged endodontically treated teeth has been increased. It is suspected that light intensity decreases as it passes throughout different materials. This can reduce the degree of conversion required for adequate bond strength throughout the length of these posts. The objective of this study was to evaluate the amount of li...

A design-oriented numerical model for the analysis of RC, FRC, and RC-FRC tunnel sections exposed to fire with different spalling parameters is presented. The conceived in two steps: first determination temperature field cross-section according parameters; second bearing capacity based on thermal section. At last, a parametric study was conducted evaluate effect curve, parameters, reinforcement...

Most of the work on card shuffling assumes that all the cards in a deck are distinct, and that in a well-shuffled deck all orderings need to be equally likely. We consider the case of decks with repeated cards and decks which are dealt into hands, as in bridge and poker. We derive asymptotic formulas for the randomness of the resulting games. Results include the influence of where a poker deck ...

A multi-zone air-handling unit was popular several decades ago due to the convenience of small sized modular units, which were inexpensive to install and easily maintained in a mechanical room. The cost and convenience proved to be of little benefit as the units perform poorly from an energy usage perspective. A “three-deck” multi-zone unit is a hybrid of its kind, and it can be very efficient ...
