We use three years data from six permanent GPS stations, in the Korean peninsula and Jeju Island, to examine the relative displacement between Jeju Island and the Korean peninsula and whether the Jeju Island l...
Small moonlets embedded in planetary rings acquire spin angular momentum by inelastic collisions of a number of ring particles. We obtain analytic expressions for the mean and mean square spin angular momenta ...
Three-dimensional inversion of Network-Magnetotelluric (MT) data has been implemented. The program is based on a conventional 3-D MT inversion code (Siripunvaraporn et al., 2004), which is a data space variant of...
The groundwater level changes induced by the 1999 Chi-Chi earthquake were well recorded at the monitoring wells in and around the Choshui River alluvial fan, Taiwan, which is adjacent to the focal region. We a...
High-quality seismic data with broad frequency band are essential for the study of seismic energy, E s , and its scaling with seismic moment, M o ...
The geomagnetic activity signature in the southern hemisphere atmospheric circulation is examined and the results are compared to those of Palamara and Bryant (2004) and other researchers for the northern hemi...
Using continuous selections, we establish some existence results about the zeros of weakly continuous operators from a paracompact topological space into the dual of a reflexive real Banach space.
We prove a fixed-point-like theorem for multivalued mappings defined on the finite Cartesian product of Grassmannian manifolds and convex sets. Our result generalizes two different kinds of theorems: the fixed...
The solvability of nonlinear equations has awakened great interest among mathematicians for a number of centuries, perhaps as early as the Babylonian culture (3000-300 B.C.E.). However, we intend to bring to o...
Let
be a nonempty, bounded, closed, and convex subset of a Banach space. We show that the iterates of a typical element (in the sense o...

Using the notion of
-distance, we prove several fixed point theorems, which are generalizations of fixed point theorems by Kannan, Meir-...
A continuation principle of Leray-Schauder type is presented for contractions with respect to a gauge structure depending on the homotopy parameter. The result involves the most general notion of a contractive...
In metric spaces, single-valued self-maps and multimaps with closed images are considered and fixed point and coincidence point theorems for such maps have been obtained without using the (extended) Hausdorff ...
Analysis of the microflora from the Mississippian deposits of southwest Spain has revealed the presence of a new species: Palaepimastoporella espielensis new gen. new sp. It is assigned to the family Seletonellac...
Isolated dental remains of pycnodont fishes are recorded from the upper Norian (Upper Triassic) of the Germanic basin for the first time. The only complete prearticular dentition differs significantly from tho...
Sedimentological and palynological data from a high alpine karst cave in Switzerland are presented. The non-layered, unsorted sediments seem to be mainly morainic, brought into the cave on Jungfraujoch by ice ...
Two isolated upper molars and a mandible with an almost complete dentition represent the first primates from the Middle Eocene Eckfeld maar (SW Eifel, Germany). They are described and determined as the cercamo...
To obtain high-strength phenol formaldehyde (PF) resin-impregnated compressed wood at low pressing pressure, the effects of resin content, preheating temperature, pressing temperature, and pressing speed on th...
The nanometer scale structure of cell walls in sugi wood (Cryptomeria japonica D. Don) and the hydration dependence were examined by the small angle X-ray scattering technique. Disk-shaped scattering patterns wer...
