摘要：Transmit waveform optimization is critical to radar system performance. There have been a fruit of achievements about waveform design in recent years. However, most of the existing methods are based on the assumption that radar is smart and the target is dumb, which is not always reasonable in the modern electronic warfare. This paper focuses on the waveform design for radar and the extended target in the environment of electronic warfare. Three different countermeasure models between smart radar and dumb target, smart target and dumb radar, smart radar and smart target are proposed. Taking the signal-to-interferenceplus-noise ratio(SINR) as the metric, optimized waveforms for the first two scenarios are achieved by the general water-filling method in the presence of clutter. For the last case, the equilibrium between smart radar and smart target in the presence of clutter is given mathematically and the optimized solution is achieved through a novel two-step water-filling method on the basis of minmax theory. Simulation results under different power constraints show the power allocation strategies of radar and target and the output SINRs are analyzed.

摘要：In this work, the intra-EDA method, which is a recently developed energy decomposition analysis scheme for intramolecular non-covalent interaction is extended from gas phase to solvated environment. It is the first analysis scheme that performs analysis for intramolecular interaction in solution. By fragmentation scheme, a molecule is divided into intramolecular interacting fragments and environmental fragments via single bond homolysis breaking. The solvent effect is taken into account by implicit solvation model. Intramolecular interaction free energy is estimated as the separated treatment of inter-fragment interactions in dielectric environment. The analysis results highlight the importance of solvent effects to intramolecular non-covalent interaction.

摘要：Dear Editor, An increasing number of single-nucleotide polymorphisms （SNP） have been identified and extensively used in genetics studies with advances in next-generation sequencing （NGS） and SNP arrays. However, due to frequent calling errors, the accuracy of SNPs of interest must usually be validated. In recent years, the single-nucleotide polymorphism genotyp-ing by fluorescent competitive allele-specific polymerase chain reaction （NiPTag, the commercial technology named KASP）, a relatively new and powerful SNP genotyping technique, relies on a mismatched nucleotide of a primer, and the mismatched nucleotide prevents amplification of the mutated allele.
