Autonomous Navigation without HD Prior Maps
… systems currently rely on High Definition (HD) prior maps both to localize, and to retrieve detailed geometric and semantic information about the environment. This information is necessary to enable safe operation of many downstream driving components including, prediction, planning, and …

Asteroseismic Study of the Subgiant HD 82074
This thesis analyzes HD 82074, a solar-mass and low-metallicity subgiant star, using ground-based asteroseismology with the CHIRON spectrometer at the Cerro Tololo Inter-American Observatory (CTIO) and interferometry with the CHARA array on Mt. Wilson. The physical parameters of subgiant stars are …

AD/HD and autism spectrum disorders in adults
… Attention deficit/hyperactivity disorder (AD/HD) and autism spectrum disorders (ASDs) are early-onset, but often life-time impairing, neurodevelopmental disorders. They are highly overlapping and seem to carry considerable risks of negative outcomes, psychiatrically and psychosocially. …

Nuclear spin coherence times of HD trapped in solid parahydrogen matrices
… studies on parahydrogen samples doped with HD molecules. Across a range of sample conditions, we observe an improvement on transverse relaxation times over previous studies, and correspondingly measure long longitudinal relaxation. We probe samples with orthohydrogen fractions three orders …

A frequency analysis of the rapidly oscillating Ap star HD 101065
… analysis of the rapidly oscillating Ap star HD 101065. The results of the intense observing program and the subsequent frequency analysis have been published and we reproduce them here in their entirety. The disadvantage in this approach is that the terseness expected by the editor of a …

Charged Pion Photoproduction Cross Section and Beam Asymmetry Measurement on HD
… d(gamma,pi<sup>-</sup>p), HD(gamma,pi<sup>+</sup>n)X were studied using linearly polarized gamma-rays with energies in the range from 260 MeV to 370 MeV at the Laser Electron Gamma Source (LEGS). A solid HD target was used in this experiment for the first time. The beam …

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY
… of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of …

Development of the Limb in Mice Bearing the Mutant Gene: Hypodactyly (Hd).
… the hindlimb digits.In 1966, Hypodactyly (symbol Hd; linkage group XI) occurred spontaneously in the inbred strain MYA/Hu (Hummel, 1971). Since the strain was homozygous for another mutant gene which interfered with classification of the new mutant, Hypodactyly was transferred by outcrossing to …

A spectroscopic study of the rapidly oscillating peculiar A star HD 134214
… a promising candidate pulsator was found in HD 156869, no such oscillations were seen in these stars. Further spectroscopic observations did discover a 21 mm pulsation in HD 116114 and as a result further investigations were confined to spectroscopy. In addition a theoretical model of the …

Children, Attention, and Nature: Evidence From AD/HD and Poor Urban Populations
The studies here are among the first to provide evidence for a systematic positive link between nature and attention in children. This work also contributes to Attention Restoration Theory, and the literature on the benefits of views of nature. Implications for design of children's spaces are …

Studying the atmosphere of HD 189733 b using the Rossiter-McLaughlin effect
… to the strong Rayleigh scattering slope of HD 189733 b that is due to possible atmospheric aerosols. The Rossiter-McLaughlin (RM) effect provides a way to probe broadband spectral features because its amplitude varies as a function of wavelength according to the effective planet radius. …

HD-tDCS over Frontal Cortex and Neuropsychological Functioning in Cognitively Impaired Older Adults
Alzheimer's Clinical Syndrome (ACS) is projected to triple in incidence over the next 30 years and is characterized by a gradual loss of cognitive and functional abilities. Mild cognitive impairment (MCI) is an earlier stage of cognitive impairment that often represents a prodromal stage of ACS. …

Analysis of Huntington Disease Caregiver Quality of Life Using The Enroll-Hd Population
<p>Huntington disease (HD) is a neurodegenerative condition inherited in an autosomal dominant manner caused by a CAG triplet repeat expansion within the <em>HTT</em> gene. Thus, HD is unique among neurodegenerative disorders with a caregiver population often burdened by both the caregiver role and …

The albedo of an exoplanet: spacebased photometry of the transiting system HD 209458
… photometry of the transiting exoplanetary system HD 209458 obtained with the MOST (Microvariablity and Oscillations of STars) satellite during 2004 and 2005. The data span 14 and 44 days respectively, and have nearly complete time coverage for both spans. The HD 209458 photometry was obtained in …

Competition between Reaction Channels in Electron Collisions of the Hydrogen Molecular Ion HD+
… of dissociative recombination of the HD+ molecular ion (HD+ + e -> H + D) was measured with high precision and on an absolute scale, at the heavy-ion storage ring TSR (Max-Planck-Institut für Kernphysik). The measured cross-section shows a previously unknown structure at electron …
