| Since the end of the Cold War, U.S. Armed Forces have participated in many operations that combine military operations against combatants in situations where the civilian population is at risk. Such complex operations, as they are now called, necessarily place troops in close contact with local civilians?and sometimes in confrontations that lead to violence. Use of force against civilians can create local tensions that undermine efforts to rebuild a society ... |

Stephen C Benoit; CINCINNATI UNIV OH
|
| Metabolic diseases are known to be tightly linked to arousal-sleep cycles and impact cognitive function. Importantly, the armed forces represent a population at significant risk for increased stress and disrupted arousal-sleep cycles. Because the incidence of metabolic disease and obesity is increasing, even in these physically fit individuals, understanding the interactions between these systems is highly significant. Further, some anti-fatigue pharmacologies (e.g.,modafinil) are already used in military settings, though their ... |

Andrea Baillo; WAYNE STATE UNIV DETROIT MI
|
| Inflammatory breast cancer (IBC) is one of the most lethal forms of breast cancer. A strong correlation has been found between inflammatory breast cancer and high levels of the growth factor amphiregulin. Amphiregulin is known to activate the epidermal growth factor receptor (EGFR) which turns on genes involved in a number of functions including cell growth. Self-sustained activation of EGFR by amphiregulin is called an amphiregulin autocrine loop. An amphiregulin ... |

|
| In order to identify stability constraints in flapping-winged MAVs, within the context of longitudinal stabilization of flight attitude, the question is examined whether insects are capable of controlling flight attitude at the temporal resolution of a single wing beat. It is found that the phenomenon of phase locking between a periodic light flash and the wingbeat of insects is suitable for the examination of the time resolution with which vision ... |

| Optical radiation can have acute and chronic effects on the tissues of the eye, especially if exposure levels exceed normal repair capabilities. In support of a Department of Homeland Security project, the transmittance properties of aircraft windscreens were measured at the FAA's Civil Aerospace Medical Institute (CAMI) for both visible and invisible optical radiation. This paper focuses on windscreen transmittance in the ultraviolet (UV) (< 380 nm) and visible (380-780 ... |

| Sulfur mustard (SM, 2, 2'-dichlorodiethyl sulfide) is an alkylating vesicating agent. The injuries resulting from SM exposure are mainly characterized by epithelial damage of the tissues through which it is absorbed, i.e., skin, eye, and respiratory tract. The skin blistering action of SM is not seen until about 12 24 hr after exposure. This time lag provides a window of opportunity for an early diagnosis of SM exposure and medical ... |

| Authors:
Robert Patterson; Amanda Taylor; Marc D Winterbottom; Byron J Pierce; AIR FORCE RESEARCH LAB MESA AZ
|
| When wearing a monocular head-mounted display HMD, one eye views the HMD symbology while both eyes view an out-the-window scene. This may create interocular differences in image characteristics that could disrupt binocular vision by provoking visual suppression, thus reducing visibility of the background scene, monocular symbology, or both. However, binocular fusion of the background scene may mitigate against the occurrence of visual suppression, a hypothesis that was investigated in the ... |

| The Microvision Spectrum SD2500 HMD, a monocular, full-color scanning laser display, display, was evaluated for optical image quality. The data indicated compliance with spectral integrity, field curvature, refresh rate, luminance uniformity, distortion and exit pupil size specifications. However, the contrast transfer function and the modulation transfer function clearly showed that the system had insignificant modulation at the Nyquist frequency. The trapezoidal shaped field-of-view was determined to be noncompliant, and the ... |

| Autostereoscopic displays offer users the unique ability to view 3-dimensional (3D) imagery without special eyewear or headgear. However, the user's head must be within limited "eye boxes or viewing zones." Little research has evaluated these viewing zones from a human-in-the-loop, subjective perspective. In the first study, twelve participants evaluated the quality and amount of perceived 3D images. We manipulated distance from observer, viewing angle, and stimuli to characterize the perceptual ... |

| The goal of this Trident Scholar project was to isolate the iris, the colored part of the eye, in a non-orthogonal, digital image of the human eye. A non-orthogonal image is an image where the eye is not looking directly at the camera. Iris pattern differs significantly between individuals (including identical twins) which allows for its use as an accurate biometric identifier. Both commercial and iris recognition system are becoming ... |

| Neuropathy target esterase (NTE) is a membrane-associated protein with serine esterase activity. A class of organophosphate (OP) compounds, used in insecticides and as chemical weapons, are capable of inhibiting NTE and lead to progressive neuropathies. We were able to isolate and characterize the human and mouse NTE (mNTE) genomic loci. We also identified a second member of the NTE family. Transgenic mice with a disrupted mNTE gene and which express ... |

| Excellent high contrast visual acuity results are achieved after laser refractive eye surgery for low to moderate refractive errors. In the early 1990's, many reports showed a decrease in low contrast acuity after laser surgery. Military aircrew work in many different arenas and have identified situations involving low light and low contrast as being the most visually demanding. Postoperative low contrast acuity has improved with newer laser techniques but there ... |

| Evidence indicates that both visual and auditory input may be represented in multiple frames of reference at different processing stages in the nervous system. Most models, however, have assumed that unimodal auditory input is first encoded in a head-centered reference form. The present work tested this conjecture by measuring the subjective auditory egocenter in six blindfolded listeners who were asked to match the perceived azimuths of sounds that were alternately ... |

| During the course of a Young Investigator Award from the Army Research Office (Materials Program) the research in the PI's group has developed into three different but related areas of scientific discovery. The first of these areas concerns the optical properties of novel transition metal nanoparticle topology which we call %"Dendnmerr Metal Nanocomposites%%. This novel metal nanoparticle system was investigated under support by the ARO for novel optical limiting and ... |

| We have studied the spectroscopy, kinetics and non-linear characteristics of conjugated organic dyes by means of a new femtosecond transient spectroscopy system that allows us to study delta A values as small as 0.003. We were able to measure accurately absorption spectra, kinetics and cross-sections of all states, transients and intermediate. These data prove that our materials have the best known RSA characteristics. All the molecules studied were found to ... |
