Abstract: The disclosure discloses a two-dimensional high-performance resonator, which is specifically an ultra-high-frequency resonator structure capable of improving an electromechanical coupling coefficient of the resonator. The resonator includes a piezoelectric layer, where an electrode layer is distributed on the upper surface of the piezoelectric layer, the electrode layer includes a plurality of electrodes arranged in a horizontal direction with a distance therebetween greater than four wavelengths, and a bridge structure is arranged on an upper portion of the electrode layer. The resonator structure can effectively improve the resonance frequency and the electromechanical coupling coefficient of the resonator, and can meet the requirements of the 5G market, and the quality factor is greatly improved.

Abstract: Aspects of the present disclosure relate to genetically modified plants comprising NODULE INCEPTION (NIN) and NIN-LIKE PROTEIN (NLP) that have been genetically altered to be responsive to cytokinin so that the NIN or NLP protein can induce root nodulation upon appropriate signaling.

Abstract: Provided by the present disclosure are an amino quinazolinone and amino isoquinolone derivatives. It is verified by numerous experiments that the compounds provided by the present disclosure have good inhibiting effects on PI3K? and PI3K?, most of the compounds have prominent inhibiting effect on PI3K?, and show strong growth inhibiting effect on PIK3CA mutant tumor cells such as human breast cancer cell strain (MCF7). Therefore, the amino quinazolinone and amino isoquinolone derivatives according to the present disclosure can be applied in the preparation of anti-tumor and anti-inflammatory medicines, and can be used as PI3K? inhibitors in the preparation of medicines for treatment of human or animal cell proliferation related tumors, the medicines comprising the derivatives any one or more of pharmaceutically acceptable salts and solvates thereof as well as pharmaceutically acceptable carriers.
