The critical zone (CZ) represents the most-shallow subsurface, where bio-, hydro-, and geospheres interact with anthropogenic activity. To characterize thickness lateral variations of CZ, here we focus on Eastern Betic Shear Zone (EBSZ), one most tectonically active regions in Iberian Peninsula. Within EBSZ, Guadalentín Depression is a highly populated area intensive agricultural activity, char...

The momentum balance of the Antarctic Circumpolar Current is investigated using both output from a highresolution primitive equation model and sea surface height measurements from the Geosat altimeter. In the Semtner–Chervin general circulation model, run with approximately one-quarter degree resolution and timevarying ECMWF winds, topographic form stress is the dominant process balancing the s...

Thin polymer "lms with lateral structures are expected to play an important role in future applications (e.g. plastic-based electronic devices). Such structures could be formed when blend "lms are spun-cast onto substrates patterned with self-assembled monolayers (SAM). The spin-coating process results in composition variations accompanied by surface undulations. We have studied both phenomena ...

In this paper we evaluate quantitatively the hypothesis that topographic modification of floor-fractured craters on the moon was accomplished predominantly by viscous relaxation. Adopting the simple assumption that the moon may be modeled as having a uniform Newtonian viscosity, we compare the observed topographic profiles for a number of floor-fractured craters with the profiles predicted from...

Computability in the limit represents the non-plus-ultra of constructive describability. It is well known that the limit computable functions on naturals are exactly those computable with the oracle for the halting problem. However, prefix (Kolmogorov) complexities defined with respect to these two models may differ. We introduce and compare several natural variations of prefix complexity defin...

Sixty-day simulations of the subinertial continental shelf circulation off Oregon are performed for a hindcast study of summer 1999. In Part I, the model results are shown to compare favorably with in situ currents and hydrographic measurements obtained from an array of moored instruments and field surveys and high-frequency radar–derived surface currents. In this paper, the modeled three-dimen...

Comparisons of five data reduction methods associated with dynamic TIN models were conducted. All methods were applied to real world Light Detection and Ranging (LIDAR) topographic data. Data reduction is based on point selection by thresholding in dynamic Delaunay triangulation together with random point selection. The triangulation criteria used include Delaunay and hybrids of Delaunay and da...

BACKGROUND/AIM Structural changes in the lamina cribrosa have been implicated in the pathogenesis of glaucomatous optic atrophy. The aim of this study was to determine a measure the surface variability of the cup floor in normal subjects and patients with glaucoma. METHODS A sample of age matched normal subjects (NN), patients with low tension glaucoma (LTG), and primary open angle glaucoma (...
