Abstract: A weakly coupled enhanced graphene film includes an enhanced graphene structure based on weak coupling, wherein the enhanced graphene structure based on weak coupling comprises a plurality of graphene units stacked vertically; the graphene unit is a single graphene sheet, or consists of two or more graphene sheets stacked in AB form; two vertically adjacent graphene units are weakly coupled, to promote the hot electron transition and increase the joint density of states, thereby increasing the number of hot electrons in high-energy states; the stacking direction of the graphene units in the graphene structure is in the thickness direction of the graphene film; and the graphene film enhances the accumulation of hot electrons in high-energy states by the enhanced graphene structure based on weak coupling.

Abstract: In an input method, an electronic device detects a pre-modification operation on M target words. The pre-modification operation includes entering first input information that corresponds to at least N words, where N is greater than M. The electronic device displays a first-page candidate term set in an interface in response to the pre-modification operation. The first-page candidate term set includes at least one original candidate term corresponding to the first input information and at least one sub-candidate term corresponding to some of the first input information. The original candidate term includes at least N words, and the sub-candidate term includes M words.

Abstract: In a method for providing a reminder regarding charging an electric vehicle, a device determines, based on a habitual-charging battery level range of a user and a user type, whether the user needs to be reminded to perform charging. The habitual-charging battery level range has a minimum battery level and a maximum battery level. The user type includes a home charging user or a non-home charging user. The charging device then sends a proper charging reminder notification to the user when it is determined that the user needs to be reminded to perform charging.

Abstract: The present invention belongs to the field of medicine and specifically relates to the use of Selonsertib in the preparation of drugs for the treatment of cancer. The Selonsertib is the English name of the compound 5-(4-cyclopropyl-1H-imidazole-1-yl)-2-fluoro-N-(6-(4-isopropyl-4H-1,2,4-triazol-3-yl)pyridine-2-yl)-4-methylbenzamide, and its chemical formula is C24H24FN7O, CAS No.: 1448428-04-3. The results of the present invention show that Selonsertib can efficiently inhibit the activity of RSK4 kinase, and has a significant inhibitory effect on the growth of a variety of tumors, and can reduce the resistance of tumors to EGFR-TKI-targeted drugs when combined with EGFR-TKI-targeted drugs. Selonsertib in combination with Anti-PD1 has a significant effect on inhibiting tumor growth compared with the drug alone. The pharmaceutical composition containing Selonsertib provided by the present invention has a good application prospect in the targeted therapy of a variety of cancers.

Abstract: The present disclosure provides a parameter design method for a series passive impedance adapter applicable to a VSC-HVDC transmission system, to resolve the technical problem that high-frequency resonance may occur when impedance of a VSC-HVDC transmission system is mismatched with that of a sending-end or receiving-end grid. A parameter design goal of the present disclosure is that reactive power consumed by a series passive impedance adapter is not more than A times rated power of a converter, and a loss of the series passive impedance adapter in a fundamental wave is B times the rated power of the converter. The parameter design method for a series passive impedance adapter applicable to a VSC-HVDC transmission system in the present disclosure can realize a positive impedance characteristic within a concerned frequency band and completely eliminate a risk of harmonic resonance.
