The Moho discontinuity plays an important role in crustal growth and evolution. In this study, we delineate the geometry southern California by jointly using local Moho-reflected waves PmP teleseismic Moho-converted Ps. To well constrain geometry, have developed a two-stage process to pick created reliable travel time data set with total of 10,192 picks. We also extracted 38,648 high-quality P-...

Position-effect variegation (PEV) phenotypes are characterized by the robust multigenerational repression of a gene located at a certain locus (often called gene silencing) and occasional conversions to fully active state. Consequently, the active state then persists with occasional conversions to the repressed state. These effects are mediated by the establishment and maintenance of heterochro...

Analysis of internal structures of the Brooks Range ophiolite at the three largest and well-exposed klippen reveals a NE-SW structural grain that may parallel the original axis of magmatism of a slow spreading marginal ocean basin. Sub-parallel directions of lattice·fabrics in olivine of mantle peridotite and shape fabrics in pyroxene and plagioclase of layered gabbro indicate that asthenospher...

The type of collision between the European and the Adriatic plates in the easternmost Alps is one of the most interesting questions regarding the Alpine evolution. Tectonic processes such as compression, escape and uplift are interconnected and shape this area. We can understand these ongoing processes better, if we look for signs of the deformation within the Earth's deep crust of the region. ...

Introduction. Ps and Sp images of sub-moho negative arrivals beneath the intermountain region of western U.S. are made using dense (2-40 km station spacing) arrays shown to the left that recorded for 1-2 years: the CREST, RISTRA, SIEDCAR, LODORE, LARAMIE, BILLINGS array data combined with Transportable Array data. The nominal Sp interpretational zoo includes an LAB arrival thought to manifest t...

The number of broa.dband three-component seismic stations in southern California. has more tb an tripled recently. In th is study we use the teleseismic receiver function technique to determine the crustal thicknesses and Vp / Vs ratios for th ese stations and map out t he lateral variation of Moho dept h under southern California. It is shown t hat a. receiver function can provide a very good ...

Some common ideas and problems concerning the use of fuzzy logic for modeling unreliable networks are discussed on simple example. Approach to measuring fuzziness of different fuzzy parameters types is presented along with rules of their mutual conversions. The difficulty of keeping information at these conversions is shown.

A simple, highly efficient and green procedure for the condensation of o-phenylenediamines with 1, 2-dicarbonyl compounds in the presence of vitamin C, as an inexpensive organocatalyst, is described. Using this method, variety of quinoxaline derivatives with different electron releasing and electron withdrawing substituents, are produced in high to excellent yields at room temperature in ethano...

In this article we review previous work on religious conversions, relate this work to attachment system dynamics, and present a meta-analysis of results from 11 cross-national questionnaire studies (N = 1465) that have investigated links between religious conversions and perceivedchildhoodattachmenthistorywithparents.Twogeneralhypothesesderived from attachment theory were tested. Based on the c...
