This talk is concerned with a direct sampling method for imaging the support of a frequency-dependent source term embedded in a homogeneous and isotropic medium. The source term is given by the Fourie...
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
We will talk about the Hirota direct method and its applications to soliton solutions in (1+1)-dimensions. Both known and new examples of soliton equations will be discussed, and generalized bilinear ...
The ALICE collaboration at the Large Hadron Collider (LHC) has made the first direct observation of the dead-cone effect – a fundamental feature of the theory of the strong force that binds quarks and...
A new study by NSF-funded scientists at the Woods Hole Oceanographic Institution clarifies the influence of major currents in the North Atlantic Ocean on sea level along the coast of the northeastern ...
Global climate change, which mainly effected by human carbon emissions, would affect the regional economic, natural ecological environment, social development and food security in the near future. It’...
2018年1月28日,地球物理领域知名期刊《Geophysical Research Letters》刊发了中国地质大学工程学院宁伏龙教授研究团队的研究论文:基于粉土/砂直剪测试的含水合物沉积地层力学强度评估(Strength estimation for hydrate-bearing sediments from direct shear tests of hydrate-bearing sa...
New research out of Case Western Reserve University School of Medicine describes a mechanism by which an essential quality control system in cells identifies and destroys faulty genetic material. The ...
Hydrogen bonds and aromatic interactions are of widespread importance in chemistry, biology, and materials science. Electrostatics play a fundamental role in these interactions, but the magnitude of t...
Understanding how electric fields and their fluctuations in the active site of enzymes affect efficient catalysis represents a critical objective of biochemical research. We have directly measured the...
The electric fields produced in folded proteins influence nearly every aspect of protein function. We present a vibrational spectroscopy technique that measures changes in electric field at a specific...
Cold-atom experiments in optical lattices offer a versatile platform to realize various topological quantum phases. A key challenge in those experiments is to unambiguously probe the topological order...
Big data problems present great challenges to statisti-cal analyses, especially from the computational side. In this paper, we consider regression estimation of high-order mo-ments in big data problem...
There is increasing evidence that many kilometer-sized bodies in the Solar System are piles of rubble bound together by gravity. We present results from a project to map the parameter space of collisi...
We describe a new direct numerical method for simulating planetesimal dynamics in which N ~ 106 or more bodies can be evolved simultaneously in three spatial dimensions over hundreds ofdynamical times...
