Measuring the inverse magnetostrictive effect in a thin film using a modified vibrating sample magnetometer

Creator:: Buford, Benjamin, Dhagat, Pallavi, and Jander, Albrecht
Abstract:: A method for measuring the magnetostriction of thin films using a vibrating sample magnetometer is described. We describe the design of a custom sample holder to apply an adjustable bending stress to the sample during measurement and observe the resulting change in the M-H loop.

A technique for error estimation of linewidth and damping parameters extracted from ferromagnetic resonance measurements

Creator:: Buford, Benjamin, Dhagat, Pallavi, and Jander, Albrecht
Abstract:: Ferromagnetic resonance (FMR) characterization, using a vector network analyzer (VNA), is widely used to determine anisotropy, g-factor, and Gilbert damping parameter of magnetic thin films, but results are typically reported without calculation of the measurement accuracy. We present a method of processing VNA-FMR measurements to determine both the value and...

Toy model studies of tuning and typicality with an eye toward cosmology

Creator:: Hernley, Aaron, Albrecht, Andreas, and Dray, Tevian
Abstract:: We investigate a number of simple toy models to explore interesting relationships between dynamics and typicality. We start with an infinite model that has been proposed as an illustration of how nonergodic dynamics can produce interesting features that are suggestive for cosmological applications. We consider various attempts to define the...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Estimating wind-turbine-caused bird and bat fatality when zero carcasses are observed

Creator:: Huso, Manuela M. P., Dalthorp, Dan, Dail, David, and Madsen, Lisa
Abstract:: Many wind-power facilities in the United States have established effective monitoring programs to determine turbine-caused fatality rates of birds and bats, but estimating the number of fatalities of rare species poses special difficulties. The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (if...

Theoretical study of alignment dynamics of magnetic oblate spheroids in rotating magnetic fields

Creator:: Tan, Mingyang, Song, Han, Dhagat, Pallavi, Jander, Albrecht, and Walker, Travis W.
Abstract:: Magnetic composites containing anisotropic magnetic particles can achieve properties not possible in corresponding bulk or thin films of the magnetic material. In this work, we discuss how planar magnetic anisotropy may be achieved in a composite by aligning disk-shaped particles in an in-plane rotating magnetic field. Previous efforts have reported...

Writing magnetic patterns with surface acoustic waves

Creator:: Li, Weiyang, Buford, Benjamin, Jander, Albrecht, and Dhagat, Pallavi
Abstract:: A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing acoustic waves, respectively. The magnetization pattern is size-tunable,...

Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

Healthcare-Associated Infection and Hospital Readmission

Creator:: Emerson, Carley B., Eyzaguirre, Lindsay M., Albrecht, Jennifer S., Comer, Angela C., Harris, Anthony D., and Furuno, Jon P.
Abstract:: OBJECTIVE. Hospital readmissions are a current target of initiatives to reduce healthcare costs. This study quantified the association between having a clinical culture positive for 1 of 3 prevalent hospital-associated organisms and time to hospital readmission. DESIGN. Retrospective cohort study. PATIENTS AND SETTING. Adults admitted to an academic, tertiary care...

Lipid/bitumen maturation by hydrothermal activity in sediments of Middle Valley, leg 139

Creator:: Simoneit, Bernd R. T.
Abstract:: The accelerated diagenesis, maturation, and catagenesis of organic matter to hydrothermal petroleum was studied in sediments from Ocean Drilling Program Leg 139 in Middle Valley, northern Juan de Fuca Ridge. Sediments at Sites 855 and 856 have experienced high heat flow resulting in accelerated diagenesis of the immature organic matter...
