With the escalating complexity in production scenarios, vast amounts of production information are retained within enterprises in the industrial domain. Probing questions of how to meticulously excavate value from complex document information and establish coherent information links arise. In this work, we present a framework for knowledge graph construction in the industrial domain, predicated on knowledge-enhanced document-level entity and relation extraction. This approach alleviates the shortage of annotated data in the industrial domain and models the interplay of industrial documents. To augment the accuracy of named entity recognition, domain-specific knowledge is incorporated into the initialization of the word embedding matrix within the bidirectional long short-term memory conditional random field (BiLSTM-CRF) framework. For relation extraction, this paper introduces the knowledge-enhanced graph inference (KEGI) network, a pioneering method designed for long paragraphs in the industrial domain. This method discerns intricate interactions among entities by constructing a document graph and innovatively integrates knowledge representation into both node construction and path inference through TransR. On the application stratum, BiLSTM-CRF and KEGI are utilized to craft a knowledge graph from a knowledge representation model and Chinese fault reports for a steel production line, specifically SPOnto and SPFRDoc. The F1 value for entity and relation extraction has been enhanced by 2% to 6%. The quality of the extracted knowledge graph complies with the requirements of real-world production environment applications. The results demonstrate that KEGI can profoundly delve into production reports, extracting a wealth of knowledge and patterns, thereby providing a comprehensive solution for production management.

Edaravone-loaded poly(amino acid) nanogel inhibits ferroptosis for neuroprotection in cerebral ischemia injury

Neurological injury caused by ischemic stroke is a major cause of permanent disability and death. The currently available neuroprotective drugs fail to achieve desired therapeutic efficacy mainly due to short circulation half-life and poor blood−brain barrier (BBB) permeability. For that, an edaravone-loaded pH/glutathione (pH/GSH) dual-responsive poly(amino acid) nanogel (NG/EDA) was developed to improve the neuroprotection of EDA. The nanogel was triggered by acidic and EDA-induced high-level GSH microenvironments, which enabled the selective and sustained release of EDA at the site of ischemic injury. NG/EDA exhibited a uniform sub-spherical morphology with a mean hydrodynamic diameter of 112.3 ± 8.2 nm. NG/EDA efficiently accumulated at the cerebral ischemic injury site of permanent middle cerebral artery occlusion (pMCAO) mice, showing an efficient BBB crossing feature. Notably, NG/EDA with 50 µM EDA significantly increased neuron survival (29.3%) following oxygen and glucose deprivation by inhibiting ferroptosis. In addition, administering NG/EDA for 7 d significantly reduced infarct volume to 22.2% ± 7.2% and decreased neurobehavioral scores from 9.0 ± 0.6 to 2.0 ± 0.8. Such a pH/GSH dual-responsive nanoplatform might provide a unique and promising modality for neuroprotection in ischemic stroke and other central nervous system diseases.

翻译是跨文化交际的方式,文化“他者”涉及译者对源语言文化的诠释行为,译者用自身文化去诠释其它文化,与译入语形成话语体系的对照,使译文产生陌生感。以自我文化为中心,会产生文化“他者”的形象,要么排斥,要么盲目崇拜,体现文化之间二元对立的思想,文化“他者”是一种负面语义效果。而从文化交流的角度上,翻译是创造性思维活动,译者诠释行为体现译者主体,译者以自身文化诠释源语言文化,翻译是文本在另一种语言中存在方式。从认知上,这种诠释行为在译文语义内容上体现两种文化的融合,而不是文化之间的二元对立,这是对文化“他者”的解构。翻译行为中,译者诠释体现为“归化”或是“异化”的翻译策略,对文化“他者”的解构对翻译教学有启示意义。

汪曾祺在1970年代末重新走上小说创作道路时,一开始写的《骑兵列传》《塞下人物传》《黄油烙饼》等小说,都是反映新中国的各类人物命运,或所谓极左路线对人民生活的危害,与当时的主流思潮如“伤痕文学”并无二致。但他很快就改弦易辙,回头写起旧时代的生活,并获得巨大的成功,声名鹊起。一般的文学史著述在介绍汪曾祺时,提及的作品主要是《受戒》和《大淖记事》,特别是前者受到更多关注,论者也就常常由此归纳出作家的创作主题和风格特征。
