| Tracking moving objects, especially human objects in surveillance systems has attracted considerable research attention. This study proposes a novel joint Electro-Optical (EO) and Infrared (IR) cameras tracking approach by employing particle filter. A centroid-based detection technique is used to discover potentially moving objects and obtain the coordinate data. Once moving targets are detected, both EO and IR features are combined to extract object templates for sampling particles. Statistic information of ... |

| The joined-wing airplane proposed by Wolkovich in 1986 is defined as an airplane that incorporates tandem wings arranged to form diamond shapes in both top and front views. The joined-wing can lead to increased aerodynamic performances as well as reduction of the structural weight. However, the joined-wing has high geometric nonlinearity under the gust load. The gust load acts as a dynamic load. In previous researches, linear dynamic response optimization ... |

During the past 10 years, among women serving in active components of the U.S Armed Forces, the proportion of first pregnancies (according to military medical records) that were complicated by GDM has more than doubled, from 3.3 to 8.1 percent. This may be associated with improved screening for GDM, increasing maternal age at first pregnancy, documented increases ... |

| In utero exposures to estrogen or estrogen mimics such may alter later breast cancer risk. Some of these estrogen-responsive pathways utilized during fetal development, are re-employed at times of tissue remodeling or wound healing during adulthood. These signal transduction systems effect proliferation, differentiation and apoptosis which in turn may affect later breast cancer risk. The heavy metal cadmium potently binds to and activates the estrogen receptor, having a half life ... |

| A prototype military bridge system using in-theater concrete with a deployable, folding truss support, and stay-in-place-form system was designed and tested. The bridge's primary advantage is a reduction in deployment requirements because of the use of in-theater materials. Numerical optimization was used in the design to reduce the deployable component weights. The results showed a potential 50% weight savings compared to the US Army Rapidly Emplaced Bridge. An experimental program ... |

| Rocket-powered launch vehicles require high thrust when taking off and high vacuum specific impulse (Isp) later in the mission. These two requirements are in conflict since a large area ratio nozzle operating at sea-level pressure is less efficient in producing thrust and the jet may separate from the nozzle causing destructive forces. Aerojet's Thrust Augmented Nozzle (TAN) concept overcomes these conventional engine limitations by injecting additional propellants and combusting in ... |

| Obesity is a risk factor for breast cancer, especially in postmenopausal women. Explanations for this association include increased production of estrogenic compounds due to aromatization of androgens to estrone in adipose tissue, and increased production of serum hormones/cytokines identified as promoters of breast tumor formation and growth. The long-term goal of the proposed research is to determine if control of obesity through centrally administered, recombinant adeno-associated virus leptin gene (rAAV-lep) ... |

| When training a recurrently connected neural network (RNN), the magnitude of the connection strengths (weights) must be limited in some way. The weights are normally constrained by either renormalizing them after each learning step, or by using a decay term proportional to the weight. For large numbers of training cycles, we show that an RNN output can become unstable with previously used weight adjustment methods. We introduce a technique that ... |
