Memory-enhanced text style transfer with dynamic style learning and calibration

Science China(Information Sciences) 2024年第4期67卷 181-196页

Text style transfer aims to rephrase a sentence to match the desired style while retaining the original content. As a controllable text generation task, mainstream approaches use content-independent style embedding as control variables to guide stylistic generation. Nonetheless, stylistic properties are contextsensitive even under the same style. For example, “delicious” and “helpful” convey positive sentiments,although they are more likely to describe food and people, respectively. Therefore, desired style signals must vary with the content. To this end, we propose a memory-enhanced transfer method, which learns fine-grained style representation concerning content to assist transfer. Rather than employing static style embedding or latent variables, our method abstracts linguistic characteristics from training corpora and memorizes subdivided content with the corresponding style representations. The style signal is dynamically retrieved from memory using the content as a query, providing a more expressive and flexible latent style space. To address the imbalance between quantity and quality in different content, we further introduce a calibration method to augment memory construction by modeling the relationship between candidate *** results obtained using three benchmark datasets confirm the superior performance of our model compared to competitive approaches. The evaluation metrics and case study also indicate that our model can generate diverse stylistic phrases matching context.

Magnesium alloys for orthopedic applications:A review on the mechanisms driving bone healing

Journal of Magnesium and Alloys 2022年第12期10卷 3327-3353页

作者： Ning Wang Shude Yang Huixin Shi yiping song Hui Sun Qiang Wang Lili Tan Shu Guo Department of Plastic Surgery The First Hospital of China Medical UniversityNo.115 Nanjing North StreetShenyang 110001China Liaoning Provincial Key Laboratory of Oral Diseases School and Hospital of StomatologyChina Medical UniversityNo.117 Nanjing North StreetShenyang 110001China Shi-Changxu Innovation Center for Advanced Materials Institute of Metal ResearchChinese Academy of SciencesNo.72 Wenhua RoadShenyangLiaoning 110016China

Magnesium(Mg) alloys have attracted a wealth of attention in orthopedic fields for their superior mechanical properties, degradability,and excellent biocompatibility. Consistently, to resolve the issues on rapid degradation, more studies are dedicated to the researches on the composition design, preparation and processing, surface modification, the degradation modes of Mg alloys. Nevertheless, the mechanisms by which Mg alloys promote bone healing remain elusive. This review gives an account of specific mechanisms on Mg alloys promoting bone healing from four aspects, immunomodulatory, angiogenesis, osteogenesis and regulation of osteoclast function. We highlight the regulation of Mg alloys on the functional status and interactions of numerous cells that are involved in bone healing, including immune cells, osteogenicrelated cells, osteoclasts, endothelial cells(ECs), nerve cells, etc., and summarize the signaling pathways involved, with the aim to provide the basis and support on future investigation on mechanisms on Mg alloys driving bone regeneration. More importantly, it provides a rationale and a general new basis for the application of Mg alloys in orthopedic fields.

车位之争,表面上是物理空间的争夺,实质上是在空间实践基础上空间表象的建构与冲突。从马克思主义实践的空间社会学视角,尤其是列斐伏尔的空间理论出发,可以发现空间实践与空间表象是客观空间与主观空间的关系,是实质空间与观念空间的关系。一方面,空间表象对空间实践处于主导性和支配性地位,通过影响空间实践获得了客观性;另一方面,空间实践因不同的行动逻辑和群体观念而发展出不同的空间表象,进而导致了空间表象的观念冲突。空间冲突将导致空间关系再生产的中断,空间生产中的行动者只有调整其沟通策略,并努力达成统一的空间表象,才能通过影响空间实践实现空间的再生产。空间冲突最终必将走向空间治理,为社区治理寻求新的方向。

服务失误是企业所竭力避免的,实践和学术研究都表明,在遭遇服务失误后,顾客满意度和顾客再购买意愿都会下降,而不同原因导致的服务失误对顾客满意度和购后行为的影响也不同。本文对于服务失误的原因重新做了分类,除了既有研究已关注的“内因”和“外因”外,补充了可能导致服务失误的第三方原因。通过情景模拟实验法,比较了这三种原因的服务失误对顾客满意度和购后行为的影响。结果发现,“外因”导致的服务失误对于顾客的负面影响最大,“内因”导致的服务失误对于顾客的负面影响最小,第三方导致的服务失误对于顾客的负面影响介于前两者之间。但无论是什么原因导致的服务失误,相同的服务补救引发的顾客反应是相同的。
