Groundwater plays a significant role in influencing the growth and distribution of Robinia pseudoacacia L. plantations, with largest planting area Yellow River Delta, by affecting soil water–salt environment. This study aimed to clarify mechanism groundwater’s influence on R. under different levels groundwater mineralization (GWM) depth (GWD). We simulated GWM 0, 2 4 g L−1, GWD 0.8, 1.3 1.8 m. ...

BACKGROUND AND PURPOSE Type 2 FCD is one of the main causes of drug-resistant partial epilepsy. Its detection by MR imaging has greatly improved surgical outcomes, but it often remains overlooked. Our objective was to determine the prevalence of typical MR imaging criteria for type 2 FCD, to provide a precise MR imaging pattern, and to optimize its detection. MATERIALS AND METHODS We retrospe...

We study quantum dynamics of three dressed Bose-Einstein condensates in a high-Q cavity. The quasiparticle excitation spectrum of this system is found numerically. The stability of the quasiparticle excitation is analyzed. It is shown that there exist instabilities in the excitation spectrum. Typeset using REVTEX 1 ] Recently, multicomponent Bose-Einstein condensates (MBEC’s) [1,2] have attract...

Plasma-facing materials (PFMs) in the ITER divertor will be exposed to severe conditions, including exposure transient heat loads from edge-localized modes (ELMs) and plasma particles neutrons. Tungsten is material chosen as PFM for divertor. In previous tests, bubble formation ITER-grade tungsten was detected when fusion relevant conditions. For this study, simultaneous ELM-like D/He (6%) line...

BACKGROUND Prediction of timing for the onset and peak of an influenza pandemic is of vital importance for preventive measures. In order to identify common spatiotemporal patterns and climate influences for pandemics in Sweden we have studied the propagation in space and time of A(H1N1)pdm09 (10,000 laboratory verified cases), the Asian Influenza 1957-1958 (275,000 cases of influenza-like illne...
