 | Assessing the neurocognitive demands of humans operating in real-world environments is critical for understanding Soldier performance. However, the capability to reliably measure brain dynamics of Soldiers in operational environments is a major challenge because of inherent artifacts in real environments. This study quantified the integrity of electroencephalographic (EEG) signals as a function of varied motion artifacts that are characteristic of realistic environments. Participants performed a standard auditory discrimination task in ... |

| A New Approach to the Characterization and Detection of Nonstationary Environments and Channels |

| Authors:
Leon Cohen; HUNTER COLL NEW YORK
|
| A new method to study nonstationary systems and channels that applies to both the time-variant and time-invariant case has been developed. It is shown that a significant simplification occurs when systems are formulated in phase space. The phase space can be time-frequency for the usual formulation of channels/systems, or position-wave number for dispersive channels and pulses. In the standard textbook approach of input-output relations and system functions, the relations are ... |

| Controlling Interfacial Properties in Nanoenvironments: A Novel Technique of Intelligent Systems |

Yu Qiao; AKRON UNIV OH
|
| In summary, it is validated experimentally that nanoporous materials of non-hysteretic sorption isotherm curves can be employed to develop volume memory systems. Under the working pressure, as temperature changes, the effective wettability varies, and thus the liquid tends to either infiltrate into or defiltrate out of the nanopores, resulting in a thermally controllable actuation behavior. Due to the large specific surface area, the wettability variation is greatly amplified. Consequently, the ... |

Douglas Nowacek; DUKE UNIV BEAUFORT NC MARINE LAB
|
| During this project, we investigated the physical forces that right whales experience in their marine environment and the biological adaptations of these whales to these forces. In comparison to locomotion in a terrestrial environment, energy for marine locomotion is predominately directed towards overcoming the forces of drag and buoyancy (instead of the force of gravity). North Atlantic right whales (Eubalaena glacialis) have been characterized as slow-swimming cetaceans that trade off ... |

| This research has two main components: (1) a new, wavelet-based cascade model for intermittent (uneven) distributions of objects in terrestrial environments and (2) a complementary analysis of intermittent wave scattering. Taken together, these developments facilitate realistic statistical descriptions of the performance range (uncertainty) associated with sensing and communication systems. The wavelet cascade model uses a simple set of decay processes to generate complex random media with realistic organization of objects ... |

|
| Environmental exposures undoubtedly play a role in the development of breast cancer, but few individual agents have been unequivocally identified as risk factors. Rather than seek out individual agents, the authors hypothesize that the cumulative effect of environmental exposures on an individual can be quantified through a blood-based assay, and further, that such a "biomarker" might distinguish breast cancer patients from age-matched controls. These biomarker data can then be added ... |

| Excessive body weight, particularly in children, is a growing concern in the United States and around the world. Body weight is affected by feeding behavior and physical activity. Environmental factors affect feeding behaviors and physical activity; therefore, environment is an important influence on body weight. Three separate experiments examined the behavioral effects of environmental enrichments on feeding, activity, and body weight. For the first two experiments, subjects were 36 adolescent, ... |

| The clinical use of exercise testing to evaluate an individual's cardiorespiratory reserve and to enable the appropriate prescription of aerobic activity has attained wide medical acceptance. The physiologic stress from the metabolic intensity imposed by exercise, however, is only one consideration in testing and prescription. An equally important stress is that imposed by the environment (heat, cold, altitude, and air quality). Both exercise and environment alter the physiologic responses of ... |

| Environmental stress is an important, but indirect, contributor to instability and potential conflict. It acts in combination with other socio- economic and institutional factors to produce the effects that lead to instability. Several theoretical and mathematical models of state instability and failure have been developed but are too complex for practical application. Thus, a simpler framework, the Stability Pyramid, is proposed to better identify and communicate the status of national ... |
