Numerical simulation of three-dimensional (3D) seismic wavefields forms the basis research on migration methods 3D data based wave equations. Because precision wavefield extrapolation determines imaging accuracy to a certain extent, it is very important study how enhance forward modeling wavefields. Thus, we build an optimized staggered-grid finite-difference (SFD) method with high two-dimensio...

The Conserved Domain Database (CDD) is a compilation of multiple sequence alignments representing protein domains conserved in molecular evolution. It has been populated with alignment data from the public collections Pfam and SMART, as well as with contributions from colleagues at NCBI. The current version of CDD (v.1.54) contains 3693 such models. CDD alignments are linked to protein sequence...

As Covid-19 pandemic led to abrupt transformation from face-to-face classes online learning, questions arise as which among the lists of teaching strategies can be considered best practice for learning. Hence, this study assessed approach three-domain strategy theories: behaviorism; cognitivism; and social constructivism lived experience professors in Asian Institute Maritime Studies Philippine...
