[1] We conduct three-dimensional subduction experiments by a finite element approach to study flow around slabs, which are prescribed based on a transient stage of upper mantle subduction from a laboratory model. Instantaneous velocity field solutions are examined, focusing on the toroidal vs. poloidal components as a function of boundary conditions, plate width, and viscosity contrast between ...

Fitting a Gaussian curve to real settlement data is of practical use because the parameters that describe the curve, namely volume loss, maximum settlement and trough width, are conceptually easy to understand and can be compared at different locations and for different tunnel sizes, depths and construction methods. Where the magnitude of surface settlements is small, it can be difficult to obt...

Pleistocene glaciers revealed numerous types of land formations in their retreat northward during climatic warming. The postglacial landscape contains various features, such as moraines, flutes, and drumlin fields. Drumlin fields in southeastern Wisconsin and west central New York are compared in terms of drumlin morphology to ascertain regional differences between drumlin fields formed by diff...

Riparian forests can provide an important service for aquatic ecosystems by sequestering hillslopederived sediments. However, the width of a riparian buffer zone required to filter sediments is not yet wellunderstood. Here are used two complementary tracers to measure sediment retention. The 137Cs technique and the soil carbon isotopic ratios (delta13C) are utilized to investigate sediment depo...

Metoisops akingbohungbei, M. groehni, M. punctatodiffusus, M. intergerivus, M. grabenhorsti, M. variabilis, and M. consimilis are described as new species from the late Eocene Baltic, Ukrainian, (Rovno) and Saxonian (Bitterfeld) amber. The new diagnosis of the genus Metoisops and also all species of this genus presented, along with illustrations. An analysis of all studied specimens referring t...

We propose to perform a measurement of the η → γγ decay width at a 3% precision via the Primakoff effect in Hall D with the GlueX standard setup. This experiment will not only resolve a long standing puzzle of the experimental discrepancy between the Primakoff and collider measurement results, but will also significantly reduce the overall error bar on this important quantity, resulting in a di...

The problem considered here is to determine the shape of a symmetric twodimensional plate so that the drag of this plate in infinite cavity flow is a minimum. With the flow assumed steady and irrotational, and the effects due to gravity ignored, the drag of the plate is minimized under the constraints that the frontal width and wetted arc-length of the plate are fixed. The extremization process...

Most of the existing total knee arthroplasty (TKA) implants are designed to suit the knee anatomy of the Western population. Studies have shown that there are striking variations in knee morphology between the Asian and Western population. We conducted a case-control study to investigate the anthropometry of the Indian arthritic knees using three dimensional knee models and evaluated them morph...

Central black hole masses for 118 spiral galaxies representing morphological stages S0/a through Sc and taken from the large spectroscopic survey of Ho et al. (1997) are derived using K s-band data from 2MASS. Black hole masses are found using a calibrated black-hole – K s bulge luminosity relation, while bulge lumi-nosities are measured by means of a two-dimensional bulge/disk decomposition ro...
