Perubahan zaman menyebabkan peningkatan kemajuan teknologi yang sangat pesat baik di negara berkembang maupun maju. Berkembangnya era globalisasi dalam ekonomi berbasis pengetahuan merevolusi pemahaman tanggung jawab sosial perusahaan atau biasa kita sebut CSR. PT Menara Indonesia menunjukkan implementasi kenyataannya melalui program yaitu Kampus Gratis untuk kaum marginal. Namun, un…

Lactates play key roles in facilitating or protecting the development of a cancer in most cancer types. While its beneficial effects to cancer development have been extensively studied, very little is known about what derives the high-level production of lactates in a cancer throughout its entire development. Here we present a novel computational analysis of transcriptomic data of nine primary …

Transposable elements, once described by Barbara McClintock as controlling genetic units, not only occupy the largest part of our genome but are also a prominent moving force of genomic plasticity and innovation. They usually replicate and reintegrate into genomes silently, sometimes causing malfunctions or misregulations, but occasionally millions of years later, a few may evolve into new func…

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…
