Ultra-wideband (UWB) nonlinear frequency modulation (NLFM) waveforms have the advantages of low sidelobes and high resolution.By extending the frequency domain wideband synthesis method to the NLFM waveform, the synthetic bandwidth will be limited, and the grating lobe will grow as the number of subpulses increases at a fixed synthetic bandwidth.Ai
For survival and quality of human Pilsner Beer Glasses life, the search for better ways to ensure food safety is constant.However, food contaminants still threaten human health throughout the food chain.In particular, food systems are often polluted with multiple contaminants simultaneously, which can cause synergistic effects and greatly increase
Cathodic protection is widely used to protect metal structures from corrosion in marine environments using sacrificial galvanic anodes.These anodes, either in Zinc, or preferentially nowadays in Al-Zn-In alloys, are expected to corrode instead of the metal structures.This leads to the US License Plate Hat release of dissolved species, Zn2+, Al3+, a
Using benzenediamine and benzenedithiol molecular junctions as benchmarks, we investigate the widespread analysis of the quantum transport conductance in terms of the projected density of states (PDOS) onto molecular orbitals (MOs).We first consider two different methods for identifying the relevant MOs: (1) diagonalization of the Hamiltonian of th
Grassland degradation presents overwhelming challenges to biodiversity, ecosystem services, and the socio-economic sustainability of dependent communities.However, a comprehensive synthesis of global knowledge on the frontiers and key areas of grassland degradation research has not been achieved due to the limitations of traditional scientometrics
