Characterizing the Role of Magnetic Cues Underlying Spatial Behavior
… the functional significance of other forms of behavioral responses mediated by magnetic cues, such as spontaneous magnetic alignment, is less clear. The following research was carried out to investigate the mechanisms underlying magnetic orientation in vertebrates and invertebrates. This …

Spatial Behavior and Population Estimation of the Alligator Snapping Turtle (Macrochelys Temminckii)
… number of <em>M. temminckii </em>using both spatially explicit capture recapture and a novel plot sampling model using time lapse photography. The results of this study give valuable insights into the habitat preferences of <em>M. temminckii </em>which may provide guidance to managers and …

Gender-Specific Differences in Spatial Behavior of the Flesh Fly, <em>Sarcophaga crassipalpis</em>.
… male flies showed significantly higher levels of spatial separation among themselves (as determined from nearest neighbor analyses) than did females: males were distributed uniformly whereas females were nearly random. The male spatial behavior occurred during the photophase but not the scotophase …

Species Composition and Spatial Ecology of Amazonian Understory Mixed-Species Flocks in a Fragmented Landscape
… In this research, I assess how flock spatial behavior and species compositions are affected by changes in habitat structure. I followed 29 mixed-species flocks in different landscapes types such as secondary forests, forest fragments of 10 and 100 ha, and mixes of primary and secondary …

Interactions between anterior thalamus and hippocampus during different behavioral states in the rat by Héctor Penagos.
… cognitive functions such as episodic memory and spatial navigation. Earlier work in rodents has demonstrated that hippocampal cell ensembles re-express firing profiles associated with previously experienced spatial behavior. Such recapitulation occurs during periods of awake immobility, slow wave …

Hearing health care in the United States: A multi-scale spatial & political economic analysis of health care policy and access to audiology services
… that structural, top-down pressures shape their spatial behavior and practice, which cumulatively affects the availability and accessibility of their services at multiple scales. Hearing loss is the third most prevalent disability in the United States, affecting 20 percent of the U.S. population …

Spontaneous directional preferences in taxonomically and ecologically distinct organisms: examining cues and underlying mechanisms
… field plays an important role in encoding spatial information in novel surroundings, and may help to organize multiple locales into a 'mental map' of familiar space. Given the importance of magnetic input in many aspects of spatial behavior, another important finding was that magnetic …

Circuit-Level Modeling and Simulation of Semiconductor Lasers
… lasers (VCSELs) and their strong thermally and spatially dependent behavior. The first approach, implemented in both HSPICE and SABER, is a simple thermal model which incorporates a temperature-dependent offset current into the standard laser rate equations in order to describe thermally …

Optical rheology for live cell membranes
… of RBC in terms of temporal frequency and spatial frequency is retrieved 'without contact, for the first time to our knowledge. Sub-nanometer sensitivity diffraction phase and fluorescence microscopy (DPF) quantifies non-invasively three dimensional morphological information of live cell …

Dynamic Fluctuations in Emotion and Space Representation: A Functional Cerebral Systems Approach to Right Hemisphere Dysfunction
… disorders of emotion are compared with those of spatial representation. The current experiment tested some of these hypotheses about emotion regulation and spatial representation in the right hemisphere using nonclinical subjects under a cortical stress paradigm designed to mimic the conditions …

Apical and radial pH diffusion through root dentin from five modern intracanal medicaments: a twelve-week evaluation of alkaline dynamics
… ex vivo study characterized the temporal and spatial behavior of hydroxyl ion diffusion through root dentin from five contemporary intracanal medicaments over 12 weeks, with emphasis on vehicle composition and apical diffusion beyond the medicament terminus. METHODS: Sixty-six extracted …

A probabilistic model for estimating demand for selected existing rural community hospitals that may be facing closure in West Virginia
… in West Virginia to test the Huff Consumer Spatial Behavior model for estimating demand at four hospitals that may be facing closure. It was found that through application of the Huff model that in a small system of hospitals and patients, each patient location (i.e., zip code) will send …

Space and motion : data based rules of public space pedestrian motion
… by assumptions regarding people's motion behavior or by analogous models such as collision avoidance methods. However, the use of data from people can elucidate spatial behavior. Advancements in depth camera sensors and computer vision algorithms have eased the task of tracking human …

A feature-based framework for evaluating synthetic human mobility
… three real-world urban datasets with distinct spatial structures. Region-specific fine-tuning enhances realism, while persistent discrepancies in multi-scale entropy coefficients reveal challenges in modeling transitions between dwell and trip states. Incorporating road network information …

Optically induced ferro- and antiferromagnetic dynamics in the rare-earth metal dysprosium
… fundamental differences in the temporal and spatial behavior of ferro- and antiferrmagnetic dynamics are assinged to an additional channel for angular momentum transfer, which reduces the antiferromagnetic order by redistributing angular momentum within the non-parallel aligned magnetic …
