Abstract: A telescopic suitcase and a novel pull rod and suitcase body thereof are provided. The telescopic suitcase includes a novel pull rod and a suitcase body, where the novel pull rod includes suitcase body fixing tubes, suitcase body moving tubes, and telescopic rods; the suitcase body includes an upper suitcase body and a lower suitcase body; a lower end of the upper suitcase body is sleeved outside the lower suitcase body; a capacity of the suitcase is adjusted by changing relative positions of the upper suitcase body and the lower suitcase body; the suitcase body moving tubes each include an upper end fixedly connected to the upper suitcase body and a lower end provided with a first locking element; the suitcase body fixing tubes are fixedly connected to the lower suitcase body; the lower end of the suitcase body moving tube is sheathed inside the suitcase body fixing tube.

Abstract: A method for residual adapters for few-shot text-to-speech speaker adaptation includes obtaining a text-to-speech (TTS) model configured to convert text into representations of synthetic speech, the TTS model pre-trained on an initial training data set. The method further includes augmenting the TTS model with a stack of residual adapters. The method includes receiving an adaption training data set including one or more spoken utterances spoken by a target speaker, each spoken utterance in the adaptation training data set paired with corresponding input text associated with a transcription of the spoken utterance. The method also includes adapting, using the adaption training data set, the TTS model augmented with the stack of residual adapters to learn how to synthesize speech in a voice of the target speaker by optimizing the stack of residual adapters while parameters of the TTS model are frozen.

Abstract: The field of new compounds and synthesis methods thereof are related, and particularly to a structure of a steric hindrance adjustable weak base light stabilizer and a preparation method and application thereof. According to the innovative light stabilizer, a steric hindrance thereof is adjusted by establishing substituent generating the steric hindrance around nitrogen atoms; moreover, an electronegativity of the nitrogen atom can be influenced by adjusting a distance of a polar group, so that an alkalinity or a nucleophilicity of the nitrogen atom is adjusted. A desired effect is obtained by adjusting a steric hindrance and a nucleophilic property or an alkalinity where the nitrogen atom is located, so that an application range of the innovative light stabilizer is widened, and the innovative light stabilizer is suitable for PC, polyester, PVC and other slightly acidic or certain electrophilic polymer materials to serve as a light stability protecting aid.
