The χ2 principle and the unbiased predictive risk estimator are used to determine optimal regularization parameters in the context of 3-D focusing gravity inversion with the minimum support stabilizer. At each iteration of the focusing inversion the minimum support stabilizer is determined and then the fidelity term is updated using the standard form transformation. Solution of the resulting …

Tibetan Plateau uplift and global cooling have generally been thought to have caused the drying of the Asian inland, but how and when these factors drove the aridification is unknown. The Xining Basin at the NE Tibetan Plateau received continuous Eocene–Miocene fine-grained sediments, providing an excellent opportunity to address this question. Here we present detailed rock magnetic and dif…

The presence of mesoscopic heterogeneities in fluid-saturated porous rocks can produce measurable seismoelectric signals due to wave-induced fluid flow between regions of differing compressibility. The dependence of these signals on the petrophysical and structural characteristics of the probed rock mass remains largely unexplored. In this work, we derive an analytical solution to describe the …

Global navigation satellite systems (GNSSs) have revealed that a mega-thrust earthquake that occurs in an island-arc trench system causes post-seismic crustal deformation. Such crustal deformation data have been interpreted by combining three mechanisms: after slip, poroelastic rebound and viscoelastic relaxation. It is seismologically important to determine the contribution of each mechanism b…

Selenium (Se) is an important micro nutrient that mainly occurs in protein sin the form of selenocy steine and in tRNAs in the form of selenouridine. In the past 20 years, several genes involved in Se utilization have been characterized in both prokaryotes and eukaryotes. However, Se homeostasis and the associated regulatory network are not fully understood. In this study, we conducted compara…

Hirsutella thompsonii (Ht) is a fungal pathogen of acarines and the primary cause of epizootics among mites. The draft genomes of two isolates of Ht (MTCC 3556: Ht3, 34.6Mb and MTCC 6686: Ht6, 34.7Mb) are presented and compared with the genomes of Beauveriabassiana (Bb) ARSEF2860 and Ophiocordycepssinensis(Os) CO18. Comparative analysis of carbohydrate active enzymes, pathogen–host interactio…

High-quality undergraduate education is central to the success of all life scientists. Several major bioscience educational issues are the targets of much debate, research, funding, publications, and reports (e.g., Vision and Change). Surprisingly, these issues are considered by modern bioscience instructors as unresolved, despite historical reports that claim the contrary. Here, we illustrate …

This essay traces a trajectory between the diminution of the radical objectives of secondwave feminism and the rise of postfeminism in two contemporary novels by Scottish writers. Laura Hird’s Born Free (1999) and Jenni Fagan’s The Panopticon (2012) illustrate the shrinking of radical feminist ideals to a sexual revolution appropriated by the individualism, consumerism, and competitive mar…
