We develop the Double Principal Component Analysis (DPCA) based on a dual factor structure for high-frequency intraday returns contaminated by microstructure noise. The dual factor structure allows a ...
We study stationary quantum fluctuations around a mean field limit in trapped, dilute atomic gases of repulsively interacting bosons at zero temperature. Our goal is to describe quantum-mechanically t...
At finite temperatures below the phase transition point, the Bose-Einstein condensation, the macroscopic occupation of a single quantum state by particles of integer spin, is not complete. In the lang...
One of the challenges we face as oceanographers is the wide range of spatial and temporal scales over which we must measure the physical, biological, and chemical properties and processes in the ocean...
We are all familiar with the irregular profiles from modern, high resolution conductivity-temperature-depth profilers (commonly called CTDs) freely falling vertical profilers, and towed thermistor cha...
Transmission electron microscopy (TEM) has been employed to characterize micro/magnetic structural details of magneto-optical (MO) recording TbFeCo thin films as a function of dcmagnetron sputtering p...
We report the strong correlation of deposition parameters, microstructure and stability of r.f.diode sputtered magneto-optical thin films studied by transmission electron microscopy and a magneto-opti...
We investigated the effect of dissolved hydrogen on the microstructure evolution of anocrystalline silicon. Through molecular dynamics simulations we characterize the local and overall structural feat...
We correlate simultaneously recorded magnetotransport and spatially resolved magneto optical Kerr effect (MOKE) data in Co2FeAl Heusler compound thin films micropatterned into Hall bars. Room temperat...
The microstructure and crystallographic preferred orientation (CPO) of quartz were quantified in 17 samples of natural monomineralic tabular veins. The veins opened and were= deformed, up to shear str...
Measurements using the 2-D video disdrometer (2DVD) taken during a heavy rainfall event in Huntsville, Alabama, are analysed. The 2DVD images were processed to derive the rain microstructure parameter...
The basic model for high-frequency data in finance is considered, where an efficient price process is observed under microstructure noise. It is shown that this nonparametric model is in Le Cam's sens...
Manifestations of the so-called structure induced nonlinearity are considered for the case of a granular medium, the latter being a generally accepted model of nonconsolidated rocks in seismics. The c...
Temperature profiles were made, during a period of calm weather in early autumn, in the center of the subtropical gyre in the North Pacific with free-fall microstructure instruments as well as with co...
