褐藻胶是海洋资源中含量较为丰富的多糖类物质之一,采用化学法、物理法、生物法等手段可以将褐藻胶降解为褐藻胶寡糖(alginate oligosaccharides,AOS)。AOS是由α-L-古罗糖醛酸和β-D-甘露糖醛酸组成的直链寡糖,具有抑菌、抗炎、调节免疫力等多种生物活性,这些广泛的生物活性与其结构的多样性密切相关。通过不同降解方法制备的AOS具有不同的糖醛酸组成、聚合度和一些特殊结构,因此,探究AOS结构和功效之间的关系有助于深入挖掘AOS的活性并提高AOS的应用价值。本文综述了不同AOS制备方法的反应机理、产物结构以及AOS结构与功效之间的关系,以期为AOS的开发和应用提供重要依据。

黄铁矿(FeS_(2))作为一种低成本、含量丰富的天然半导体材料,被广泛用于环境污染物的催化降解.然而,黄铁矿在自然环境中极易发生氧化(氧化黄铁矿),目前关于氧化黄铁矿催化降解有机污染物活性尚不清楚.因此,以氧化黄铁矿为催化剂,卡马西平(CBZ)为目标污染物,过二硫酸盐(PDS)为氧化剂,进行氧化黄铁矿激活PDS降解CBZ的研究.实验结果表明,在氧化黄铁矿/PDS体系中,30 min内CBZ完全降解.此外,系统地探究了催化剂剂量、PDS浓度、不同pH和共存离子对CBZ降解效率的影响.通过测量溶液中浸出的铁离子和加入螯合剂证明氧化黄铁矿中溶解的Fe^(2+)和表面结合Fe^(2+)(≡Fe^(2+))均可激活PDS促进CBZ降解.淬灭实验表明氧化黄铁矿/PDS体系中产生的活性物种为SO_(4)·^(-)、HO·、O_(2)·^(-)和1O_(2),且SO_(4)·^(-)和1O_(2)在降解CBZ中起主导作用.通过循环实验与氧化黄铁矿表征相结合,证实氧化黄铁矿良好的可重复使用性.最后,阐明了黄铁矿/PDS体系中均相反应和非均相反应协同高效降解CBZ的机理.研究结果为利用天然黄铁矿去除水体新兴有机污染物提供了新的见解.

针对语音情感分类任务面临的语音数据标注困难的挑战,该文提出了一种新的跨模态语音情感分类任务,其可以使用文本模态数据(源端)帮助语音模态数据(目标端)进行情感分类。在此基础上,提出了一种基于知识蒸馏的跨模态情感分类模型,旨在通过知识蒸馏方法将文本情感分类模型(教师模型)学习到的预训练先验知识蒸馏到语音情感分类模型(学生模型)中。该模型的特色在于无须在测试端依赖昂贵的语音识别技术,可对原始语音数据直接进行情感分类,有利于该模型在实际语音情感分类应用场景中大规模落地。实验结果表明,该文所提出的方法可以有效利用文本模态分类的经验来提升语音模态的分类效果。

In this paper, we address a novel task, namely, cognition-driven multimodal personality classification(CMPC), aiming to infer personality traits(e.g., romantic, humorous, and gloomy) shown in real time by a human being from the perspective of cognitive psychology. Specifically, this task is motivated by a cognitive difference phenomenon that humans with different personality traits tend to give different personality-oriented textual descriptions when observing an image. In particular, to tackle the inherent noise challenges in this CMPC task, we propose a tailored reinforcement learning approach, namely, multi-agent Select Net, aiming to integrate the opinion-word and image-region selection strategies to select informative opinion-word and image-region features for CMPC. To justify the effectiveness of our approach, we construct six kinds of multimodal personality classification datasets and conduct extensive experiments on the *** results demonstrate that our approach can significantly outperform other strong competitors,including the state-of-the-art unimodal and multimodal approaches.
